A Reflection

Hey everybody!

 

It’s been several weeks since I left Malawi, and I already miss the country. I miss the friends I made, the food I ate, and the fantastic culture I saw daily. 

Week eight and our final week was chaotic, fun, and bittersweet. We worked diligently and after hours almost every day to complete our project. In the end, Tatyana and I finished our training model to teach neonatal nasopharyngeal suctioning, and we were so lucky to have the chance to show nurses at the Queen Elizabeth Central Hospital our device and get their feedback. Seeing their reactions to our two months of hard work was incredibly rewarding and helped show me that I could make a difference through global health. Talking with them, we also realized some areas for improvement, and in the fall semester, I will continue working on this model. 

On our last day, we presented our devices and the project prompts we created for future teams after our needs-finding assessment. Seeing everyone share their work and unique experiences with the internship was amazing. 

Back in Houston, I am filled with a strange feeling–perhaps because I got used to daily life there or because my perspective has changed since the beginning of the summer. I thought I had an idea of what global health was about, but living in Malawi where I talked with people working in the hospital and shadowed physicians, I saw a completely different side of global health. I feel motivated to continue down the path of global health, as an engineer, physician, or anything else. 

My journey won’t end this summer just because this internship has. It’s just starting.   

I’m also including a reflection quote I wrote about the impact this internship has had on me. 

“Working with Rice360 partners at the MUBAS design studio and Queen Elizabeth Central Hospital (QECH) taught me firsthand what global health is about–beyond what I could have learned in a classroom. I’m proud–that after starting with no real engineering experience–in just two months, I learned the necessary skills and built a training model for neonatal nasopharyngeal suctioning, which I got the chance to show NICU nurses at QECH. Their positive reaction to my device was uniquely rewarding, as it taught me I could have a real impact on global health. My experiences in Malawi through the Rice360 Summer Internship were simply transformative. The friendships I made, the conversations with engineers, nurses, and doctors, and the harrowing struggles I witnessed of patients fighting every day have deeply inspired me to commit to the shared calling called Global Health.”

Goodbye Malawi

At the end of last month, we had to say goodbye to everyone and to Malawi as the internship had come to an end. It was hard to believe that it was over while having farewell dinner with the team on our last Saturday there.

Little time paired with a lot to do for the group projects made the last few days of the internship quite intense. After making some changes to the electronic components as well as the envisioned mechanical user interface from our compression therapy device project (see my previous posts for more info), we converted the circuitry developed on a few breadboards into two manual prototyping printed circuit boards (PCBs) and finalized it. Soldering all of this was a challenging process due to the space limitations, the narrow room for maneuvering as well as the need for debugging and redoing several things. We also designed and 3D printed a new box to house all of the electronics, and placed the PCBs as well as other separate electronic components inside it. While we did not incorporate the leg cuffs into this prototype, we did explore a couple of different manufacturing techniques with a local fabric, which if developed and proven successful, could help in our efforts to make a device that can be manufactured as locally as possible. Due to the tight timeline and new debugging challenges to overcome, we did not obtain all of the functionality that we had desired and which was already reflected in the user interface of the prototype. However, we did develop and implement all of the hardware components and had working PCBs which provided key functionalities to the device.

Overall, in building the existing open source device in Malawi, we adapted the design mostly due to limitations in the available materials as well as developments to the device which we wanted to incorporate. Of course, work still has to be done to finish as well as to optimize the device, but going through the process allowed us to explore the challenges and possibilities of making a device in Malawi and to learn from it.

This is what the prototype of the box looked like:

Box housing the electronic components. The side of the box also contained a switch and a charging inlet. In case you are wondering… the 3D printing of the box lid failed several times so we could not get a perfect version.

 

Lastly, the Friday before leaving, we had presentations on both our group projects as well as smaller needs-finding based personal projects. Ranken and I presented about our compression therapy device after Sanjay and Tatyana had talked about their project. Then, we all talked about our personal ones, with the topics discussed relating to maternal and neonatal health as well as prosthetics and orthotics. These research topics might become future projects for other teams, so stay tuned 🙂

Looking back, with the work done and experiences had during these two months, I have been able to develop practical engineering skills, learnt to use what is available to me and work around what is not, and gotten a better understanding of the needs and design requirements of a setting like Malawi. One does not have to go very far to find needs there and while not everything is an engineering problem, one of my biggest takeaways from this experience was seeing the direct positive impact that bioengineering can make in a setting where the resources are low but the needs are high. It is thus great to know that there are people at Rice working on developing global health technologies to help tackle medical needs in low resource settings.

I want to thank everyone who helped to make this internship possible.

Goodbye, Paula 🙂

A New Direction

Hey everybody,

After researching and developing prototypes for the forearm ROM goniometer, we shifted the focus to the nasopharyngeal suctioning training model. Meeting with clinical mentors, we found a distinct, meaningful direction to continue this project, which previous intern teams had worked on. We completed redesigned the training model from the inside out. From creating internals that were accurate to a neonate’s to placing sensors on critical points of suctioning, we aimed to update the training model into a product that can truly teach anyone wanting to learn the procedure.

And it’s been going well! Our mentors have applauded the accuracy of our training model, and the electronics have been developing as smoothly as hot solder. The weeks ahead are promising, and we look forward to showing our mentors a final prototype.

In the meantime, the school has officially opened for MUBAS, with students flowing in ready to learn and, of course, design. We’ve met all sorts of student designers, from those creating novel neonatal incubators to AI-powered vein finders. Everyone seems full of inspiration and determination, which has led to a quite powerful environment in which to work.

Of course, during the weekends, we relaxed by visiting Majete National Park and Mt. Mulanje! We had a wonderful experience, seeing all sorts of animals and swimming in the waterfall’s super cold lake. I look forward to more progress and adventures.

Muli bwanji? (‘How are you?’)

not to be confused with Mulanje, where we went hiking last week Monday! Mount Mulanje is a massif not too far away from Blantyre containing a peak called Sapitwa, which is the highest peak in Malawi. MUBAS organized the trip for the day 🙂 We did not climb that high of course (as it takes a few days), but we hiked for a bit and got to the Likhubula Falls with its ‘Dziwe La Nkhalamba’ (‘Old man’s pool’). The hike as well as the waterfalls were so beautiful. See it for yourself!

After the hike, a big part of the remaining of last week was working on the group projects. Having  tested different fabrics and done work on the gathering of materials the previous week, last week Ranken and I focused our work majorly on the electric circuitry of the compression therapy device project that we are working on (see my last post for more information on the project). We are still making changes and improving the circuits up to this day, but we made good progress last week! Overall, this has been a very iterative process so far with quite a bit of debugging as well as some reconsiderations and changes. We have also had to figure out some materials along the way and to work around what is available. With the help of the TA, we now have a pretty functional simplified system and are currently modifying the Arduino code to make sure that all the components work together as we want them to. Below is a picture of me from last week at the MUBAS design studio working on the electronics of the device.

We also continued gathering information pertaining to needs-finding last week, in particular through conversations with medical professionals of different departments from QECH. It is incredible to see and hear the amount of things that engineering could do to make a positive impact here in Malawi within the medical field!

On Friday, we also had presentations with Hillary both about our group as well as our individual site projects (if I have not introduced him so far, Hillary is the Design Studio Manager). This was a good way to compile what we have done so far as well as to get feedback for the remaining two weeks.

Lastly, this weekend, besides doing some work, I went to visit The Mandala House which has an art gallery called La Caverna Art Gallery inside as well as a very nice outside area. I really enjoyed the visit! I added a couple of pictures below:

Until next time, once more!

 

Already half way? No way!

Hi again!

It’s been a bit since my last post, but I can’t believe we are already half way through the internship! It’s gone by so quick! Let me tell you a few things that we did last week.

Like I already mentioned, Ranken and I are working on the deep vein thrombosis (DVT) compression therapy device project. DVT is a common issue that can result in complications which are life-threatening, and the idea of the project was to make a low-cost but also portable and easy-to-use compression therapy device. The project has taken a bit of a turn though, and it has now a more technical focus. After quite a bit of research, we found an existing open-source device which seems quite promising, so we are working on building it. We will of course be adjusting it to the requirements of the site where needed, and it will likely also need some more modifications along the way due to material options, further investigation, other design choices, etc. As we go, we want to make sure that we are tackling the problem appropriately, and to continue with the research on both the condition and the therapy.

More about the project below though! Let me tell you some other things first…

Later last week, Sanjay and I also got the chance to meet with one of the Rice360 student teams’ sponsors. To add some context, Queen Elisabeth Central Hospital (QECH) is the only place in Malawi where one can get an electroencephalogram (EEG). This hospital happens to be right next to MUBAS, the university where we go every day. This past year, a student team from Rice worked on making an intuitive EEG acquisition device. The idea of the project is to facilitate EEG acquisition in settings like Malawi such that this technology can reach a lot more people. We thus met with the sponsor in person to gather some feedback so that the project can be continued in the future.

After a long day of work, we were also able to attend a very nice event 🙂 Together with eight other students from the lodge, we went to one of the Sounds of Malawi Acoustic Sessions which take place in the Jacaranda Cultural Center and Maison de la France here in Blantyre. We were able to enjoy a concert by Angie Tigris, a famous Malawian singer. It was a lot of fun!

We continued with the workshops this past week as well. But going back to the project, we also got the chance to check out a commercial compression therapy device that they had at MUBAS to get a better idea of how these devices work. Below is a picture of one of the cuffs and the tubing from the device.

However, the primary focus of the project has been on figuring out the materials, which is more challenging than it seems. We have been talking with a few different people, looking for several options, and for example, yesterday, Ranken and I went around Blantyre (and even to Limbe!) visiting different fabric stores. We wanted to check out what fabrics were available locally to see if we could use any for our project. We went to five different shops! I am now regretting not having taken any pictures because they were very colorful…

Below is a very nice picture I took yesterday afternoon instead though, I hope you like it 🙂

Until next time!

A Week of Learning

Hey everybody! Week three has just finished, and the theme of the week felt like learning. From research to exploring Malawi’s history, I was thrilled by what I learned every week.

At the beginning of the week, Tatyana and I were assigned the task of designing a low-cost, intuitive device for measuring forearm range of motion (ROM). The project’s aim was to overcome training obstacles by creating a more accurate and user-friendly goniometer. By the end of last week, Tatyana and I had completed our research and wrote a comprehensive literature review detailing the gap in physiotherapy engineering development in Malawi. Fueled by the potential of the project, we quickly brainstormed and constructed a low-fidelity prototype of one of our designs.

As we approach the next week, the direction of the device is still to be determined. However, the project is full of promise, and we are eager to see where it leads us.

After completing the literature review, we received permission to work on a neonatal upper airway suctioning training model. This model had been worked on in the past and was considered complete. However, after speaking with Nest360 staff who oversee newborn care, it became clear that some common mistakes made by nurses were not accounted for in the device, necessitating additional functional aspects.

While working on our technical projects, Paula and I continued collecting data on the Rice360 devices related to quicker bacterial meningitis diagnosis. We interviewed a doctor and a chief technician from the pediatric ward and gained valuable insights into the current status and future directions of these devices.

On the weekend, we also had some fun exploring a local café that doubles as an art gallery and visiting Independence Arch, a monument symbolizing Malawi’s independence from Great Britain in 1964. We even found a United States Apollo Lunar Module replica at MUBAS! Each week brings new challenges and learning opportunities, and I am excited to continue sharing my experiences with you all.

Moni nonse! Hello everyone! (again)

Moni nonse! (hello everyone! in Chichewa). In case you did not know, Chichewa is the most commonly spoken of the many languages in Malawi.

I’m back! From Lilongwe 🙂 We returned last Wednesday and after a pretty long trip, we resumed a more regular internship schedule at MUBAS on Thursday. That day we had the first of our two workshops for the week: a review of the Engineering Design Process. We went over the key steps of what an engineer should do when it comes to taking on a new project and we ended the day with low-fidelity prototyping. For this workshop, we were given the assignment as a mock project of designing a low cost, easy-to-use and portable handwashing station to be used in Malawi with a particular focus on preventing recontamination of the hands. Sanjay worked with Tatyana, and I worked with Ranken. I don’t believe I have introduced them yet! Sanjay is my fellow Rice360 intern from Rice, and Ranken and Tatyana are the interns from MUBAS. Below are some pictures of us with our cool prototypes!

On Friday, we then had a workshop on Intellectual Property. There are no prototypes for this one, but it did open some interesting discussions! We also got introduced to our site projects: Tatyana and Sanjay will be working on a low-cost forearm range of motion (ROM) measurement device, and Ranken and I will be working on a low-cost deep venous thrombosis (DVT) compression therapy device.

After a busy week, we also got the chance to meet on Sunday and start to check out what Blantyre has for us. We visited the Blantyre Market (although we will need to pay at least one more visit as it was Sunday and most places were closed). We did get to see, for example, some handmade baskets, as well as some woodwork and paintings closeby. Below is a picture of a painting I got! We also went to the Museum of Malawi, visited the MUBAS Chichiri campus, and more!

Painting I got in town

Before I go, I want to tell you one more thing! Yesterday (besides working on the projects) we visited the Rice360 office here in Blantyre for the first time! We had the chance of hearing about some of the challenges faced as well as some possible future work that could improve newborn and maternal care. It was a great opportunity, and we were also able to get a glimpse of the neonatal care facility.

I am very excited to see where this internship will take me next!

¡Hasta pronto!

The First Jump

When a swimmer stands on the edge of a 90-foot-tall diving board, they have two options: to hesitate or embrace the jump. Our team’s first day of the internship started with what felt like being told to stand on a diving board that tall. Looking down to see what we had to accomplish, we couldn’t help but feel intimidated and uncertain, but with a job to be done, we recognized we only had one choice: to embrace the jump.

With the Nest360 Phase 2 Launch happening in the capital city of Lilongwe the next week, MUBAS wanted to showcase the work of past and present Rice-MUBAS interns. With just 7 days, we had been tasked to quickly familiarize ourselves with a variety of coding and UI software and to apply them on the device being constructed for the launch that previous interns worked on. While some might feel the dive frustrating, our team considered the challenge uniquely refreshing. We independently learned, applied skills, and found solutions to our problems, leading to tremendous personal growth. But we weren’t entirely alone; we had each other and the support of the MUBAS TAs and our mentor Mr. Hillary. Suffice to say that the first week of this internship was defined by our preparation of medical devices for presentation at the Nest360 launch.

As mentioned, our team, comprising Paula, Ranken, Tatyana, and myself, was entrusted with continuing the work of past members of this internship. Paula and Ranken focused on a crucial project, creating a dashboard for a smart syringe pump. This device aimed to provide a low-cost alternative to automated large dose IV infusions. On the other hand, Tatyana and I took on the task of assembling the electronics and programming a drip rate monitor and controller device. We meticulously assembled the sensors, displays, and Arduino, and coded the user interface and back-end logic. Our work was a testament to our technical skills and dedication to the project.

Our devices were ready to be shown, and we were ready to present. I also brought with me to Malawi medical devices created by several student teams at Rice for needs-finding. These devices included two different diagnostic tools for Bacterial Meningitis and an Intuitive EEG Acquisition device. With the teams’ consent, I took them to Lilongwe to be presented alongside the work of MUBAS, the Malawi University of Science & Technology (MUST), and Rice360’s Malawi research office.

On the morning of Tuesday, June 11, 2024, the Vice President of Malawi, Dr Saulos Chilima, was confirmed dead in a fatal plane crash the previous day. The people of Malawi describe Dr. Chilima as a “great patriot who has served the nation selflessly.” All mourn his death, and I express my condolences to Dr. Chilima’s family and the country of Malawi. To respect Dr. Chilima’s life and impact, the celebration of Nest360’s Phase 2 Launch in Malawi was postponed.

To continue the exchange of engineering development, we students of MUBAS, MUST, and the Rice360 offices met to present our work to the leadership of Rice, MUBAS, MUST, KHUeS (Medical College), and the Rice360 advisory board. The showcase proved to be an insightful and educational dialogue, continuing the body of work for global health medical devices.

Reflecting on the week and our Lilongwe showcase, I would say I pushed my limits and accomplished more than I thought possible. As we embraced the dive, our splash was brilliant. However, with another week looming, I guess the cycle continues. Its time to drag ourselves out of the water, climb to the top, and get ready to jump again.

A Short 33 Hour Flight Later

They call Malawi the warm heart of Africa. Ironically, with Malawi being in Winter, the temperatures are actually cooler than Houston’s around this time of year, but the people have been nothing but kind and gentle. From the students to adults to even the food, Malawi has provided an environment evidently warm. 

Just one week ago, I arrived in Blantyre, Malawi, to participate in the Rice360 Summer Internship Program for Global Health. Over the next two months, I’ll be working with the Malawi University of Business and Applied Sciences (MUBAS) alongside two MUBAS interns and a fellow Rice Intern. During my stay, I hope to accomplish many goals toward empowering local healthcare settings through engineering medical devices. The next series of weeks will have its highs and lows, of which I will update you all on my progress and personal adventures. In the meantime, however, I’d like to introduce myself. 

My name is Sanjay Senthilvelan. I am a rising sophomore at Rice University, majoring in Biochemistry and Chemistry and minoring in Global Health Technologies. I’d say my interest in global health originates from my family background. As Indian immigrants, my parents told me stories from their childhood of witnessing patients being failed by hospitals paralyzed by a lack of resources. When we traveled to visit family in the country, I saw what my parents spoke about firsthand. 

This experience of mine is a large reason why I want to become a doctor and why I took a global health intro class during my very first semester at Rice. I learned a more empathetic and robust perspective on global health when I had deep conversations with the professor and TAs (one of whom had gone to Malawi last year!). The semester furthered my interests, leading me to take an appropriate design for global health engineering class that spring, a leadership role in the Rice Global Health club, and compete to place 3rd in the annual Rice Global Health design-a-thon. At every step, I learned more and grew an appreciation for the work of engineers and the doctors and nurses on the ground. 

I hope to continue that learning and admiration while I’m in Malawi, where I’ll try to embody the charming Malawian warmth as I work hard to further Rice360 and MUBAS’s efforts.

This is a picture of Paula and I with Ranken and Tatyana (the MUBAS interns) at a KFC (yeah, KFC!!!) a short walk from MUBAS.

Hello, my name is Paula! (Malawi 2024 Intern Introduction)

 

Hello! I am one of the two Rice360 interns in Malawi this year! I’m excited to tell you about my experience these next two months, but first, let me introduce myself!

My name is Paula and I’m from Spain. I graduated from Rice this year with a major in Bioengineering. I am interested in medical device design and in global health. I have also lived in different places throughout my life, so I love meeting new people and learning about other cultures. Moving often also makes me really appreciate the time I can spend with friends and family. Besides that, I also like being creative and always enjoy a good mystery.

During high school, I had the chance of participating in an ‘Immersion Programme’ in Zambia which had a long-lasting influence on me. While I had already wondered how someone like me could make a change in a limited resource setting before having then, it was not until I got to Rice that I learned about global health and the impact that engineering could have in places like these. I am so happy to have the opportunity to be here (yes, I am writing from Malawi already!) and to learn and experience this firsthand.

In this internship, I will be working on different projects, including one assigned by the host (the Malawi University of Business and Applied Sciences (MUBAS)) and a personal one, as well as getting feedback for different Rice360 technologies. I will also be doing needs-finding to identify different areas or situations where possible future projects could make a positive impact. With these experiences, I hope to learn as much as possible about design in resource-constrained settings, develop my intuition and creativity in doing so, and earn and develop different engineering skills. I also hope to contribute as much as possible in the development of global health technologies.

For quite a long time leading up to the internship, I worked on preparing everything needed for the trip. Other than the long list of items that you can likely already imagine, this included for example learning as much as possible about the Rice360 projects and obtaining supplies. But as I mentioned, I am already in Malawi 🙂 I arrived on Monday after a very long trip and have been writing this entry for the past few days. Below is a picture taken from the plane right after landing in Blantyre!

Picture from the plane after landing in Blantyre

When we arrived, we were welcomed at the airport by our two fellow interns and the Design Studio Manager from MUBAS. On Tuesday, we familiarized ourselves with MUBAS, got introduced to a lot of people, started learning about the work for the next few days, and got help from the MUBAS interns with some other arrival tasks.

Views from the lodge when going for breakfast the first morning (Tuesday)

Next Tuesday is the NEST Program Phase 2 Launch in Lilongwe, so the Design Studio has been very busy working on some projects. To help with that, we were tasked, in pairs, with creating a User Interface for one of the projects. We have been focused on this work since Wednesday. It has thus been a very busy start, but I have gotten to learn new things already!

I feel like I will be able to gain a lot from this experience, both as an engineering and a citizen of this world, and I hope that I can also contribute to a positive impact through my work here. I only have a few pictures for now, but I wanted to share one more of a sunset from the lodge:

Until next time!
