Challenge: no. 2: Measurement of urinary continence in hospitalized patients
Problem: Measuring urine output is still done manually. Even today, a nurse or a doctor has to visit the patient if they want to get information. The way of measuring urine output today is inaccurate. Devices which measure urine volume in urine bags still do not exist.
Solution: Our solution was to create a hardware device which will measure urine output accurately. It sits between the bed and the catheter bag. Data is sent via Wi-Fi and stored in the database where the doctor or nurse can easily see charts and important values without disturbing the patient, especially at night. The device should display actual data, be power efficient and maintenance-free as much as possible.
Impact: The device gives the opportunity to have instant information about the urine volume and at the same time eliminates the repetitive work of doctors and nurses. It’s measurements are also more accurate. The patient is not disturbed during the night.
Feasibility & financials: The design of the device is sophisticated, but still very straightforward. The case can be 3d-printed and the price of the entire hardware is 25 USD, which allows mass production if necessary. It can be attached to any bed thanks to the changeable 3d-printed holders. The device does not rely on any special or unavailable technology which makes it easily usable.
What you have built at the hackathon - text explanation + code (e.g. GitHub link): It was a journey of modeling, 3d-printing, soldering, programming and testing. At first, we tested the weight sensors, then connected an e-ink screen with a battery and finally printed a case for it. Measured weight of urine is sent to InterSystems using the FHIR standard. Actual data are shown on the screen and more data at hackhealth.kovac.top/view, where measurements and charts are. We achieved a 30 day battery life of the device and pretty accurate urine measurements. GitHub: bit.ly/3DCApVq
What you had before the hackathon, please mention open source as well: We decided to choose this challenge before the hackathon, so we prepared all necessary components in advance. Microcontrollers, sensors, 3D printer, soldering iron and a lot of handy stuff. Being well prepared gave us flexibility and it saved a lot of time during the hackathon.
What comes next and what you wish to achieve: In the next step, we would like to enrich our solution with a color sensor for more data (the place for it is already in the case). Then we would like to focus on improving accuracy, power efficiency and data presentation. There is a potential in this device, so we would like to put the equipment into practice and thus facilitate the work of many employees.
