Our project is a portable hemodialysis machine designed to be lightweight and backpack-sized, allowing patients with kidney failure to receive dialysis anywhere. It includes a compact filtration system with reusable dialysate technology, powered by a rechargeable battery powered by solar panels for easy mobility. The device connects to a mobile app that monitors key information such as battery level, treatment progress, water quality, and filter status, while also sending alerts and data to healthcare providers for remote supervision. This design aims to make dialysis more accessible, convenient, and inclusive, especially for patients in remote or low-resource areas.

# data[].attributes.body
The device should improve access to dialysis for people in remote, low-income, or underserved areas, reducing the need for frequent hospital visits. It promotes health equity, independence, and better quality of life for patients. It’s our responsibility to ensure it’s affordable, safe, and easy to use for all.

# data[].attributes.body
We must ensure patient safety, data privacy, and informed use. The device should meet medical standards, give accurate readings, and alert users to any risks.

Dialysis traditionally uses large amounts of water, power, and disposable materials. The portable system should minimize waste, recycle or regenerate dialysate and use energy-efficient components. End-of-life recycling plans and reduced single-use plastics support sustainable healthcare.

# data[].attributes.body
Access to dialysis remains a major challenge for people with kidney failure, especially in remote or low-income communities. Current machines are large, expensive, and require specialized facilities, limiting independence and equitable access to care. There is a need for a portable, affordable dialysis solution that enables all patients, regardless of location, income, or ability, to manage their treatment safely and live more independently.

# data[].attributes.body
This design is inclusive because it addresses key barriers to healthcare access faced by diverse users worldwide. Its portable, wheelchair-attachable, and trolley-compatible form ensures ease of mobility for people with varying physical abilities. The recyclable water system makes it sustainable and practical for regions with limited water resources, while the solar panel recharge option enables use in areas without reliable electricity and on the go. Paired with an intuitive app for monitoring and remote medical support, the device supports patients from different socio-economic and geographic backgrounds to manage their dialysis safely and independently.
