Wanting to do something to help in the Covid-19 pandemic, after three major pivots caused by actually talking to health personell, I ended up with the idea to design a bed, targeted at Covid-19 patients during the pandemic.
What it does
The bed positions the patient face up, but is able turn the patient face down by rotating the entire bed. This saves about 2 hours of nurse-time per ped, per 24h. This means for each four beds, it frees up one nurse.
The bed solves three problems at the same time:
- How can we expand Intensive Care capacity, fast enough?
- How can we reduce mortality of Covid-19 patients?
- How can we reduce the workload on intensive care nurses?
The bed attempts to solve these three problems by:
- The bed is built everywhere, by any carpenter, maker anywhere in the world. Only drawings and instructions is actually distributed.
- Prone positioning (face down) can reduce mortality of many severe Covid-19 cases by 50%. But prone position in a normal hospital bed (swimmers position) is not ideal, particularly for heavy and/or obese patients. We improve prone positioning by increasing pressure on torso and collarbone, but reducing pressure on abdomen. This improves breathing and oxygenation compared to swimmers positions. Increased turning frequency reduce complications such as pressure ulcers.
- When patients are positioned in prone, they need to be turned around every 12-16 hours. The turning maneuver is executed by nurses, but is difficult and risky. Ideally, a turning maneuver requires 5 intensive care nurses working together in up to 30 minutes. The rotating bed allows one or two nurses to do the turning maneuver in a few minutes.
How I built it
We are working designing the prototype, and hope to have it built quickly using any CNC enabled woodworking facility anywhere in the world.
Challenges I ran into
Our chief challenges are:
- An unknown solution : Using prone for ARDS (Covid-19) was added as a recommendation in 2018. But many hospitals doesn't know this, or have not developed enough experience with prone to use it. This device simplifies prone, but if they are not using it then they will not be interested.
- What is the point of a rotating bed? : If the hospital are not putting patients in prone, what difference does it make if you can rotate the patient in prone? The hospitals need to both understand that proning Covid-19 is important, and experience problems with nurse capacity due to turning.
- Looks : Because it's plywood, it looks like something from the fifties. Some places this means it will not be accepted. We would love to make it from stell and plastic, but it takes more time to build it. So there is a tradeoff, but how is it weighted?
- Hygiene : Will a painted plywood design be acceptable from a hygiene perspective?
What's next for MakerMedical
We need to find more people willing to help develop the concept
