Testing our product along the development process is an important priority for us. We have conducted functionality tests in the hospital lab, usability tests at nursing homes and technical testing in our workshop. The latest test showed great results in pressure relief!
Using a pressure sensor mat
In cooperation with a helpful pressure sore expert we have been investigating how our movement is actually relieving pressure on the body. There are three zones that are especially prone to pressure sores when lying without movement over time; shoulders, hip and lower legs. By using a pressure sensor mat we were able to measure how the pressure was distributed in these areas when getting turned in our turning mattress.
Here is a test from the most crucial zone, the hip:
Clearly pressure relieving
The first observation is that the red area with the strongest pressure alternates from side to side. However, this is of course expected for any methods of turning. What makes our technology unique is the distribution of pressure relief. It might not be noticed for the common person, so here is a short explanation from the film:
1. Expanding the support area: By making the underlay wider (5 sec) the overall pressure decreases because the body gets an broader support instead of smaller and heavier areas. Thereof the body gets a milder pressure on the part in touch with the mattress than other methods such as manual turning or flat turning mattresses.
2. Relieving pressure in the crucial areas: The most common place to develop pressure sores is actually not on the red areas in the film, but in the lower spine. As the wound occurs where our skeleton is surrounded with a thin skin layer, the buttocks are protected by the thick tissue of the gluteus maximus muscle. By expanding the support area the pressure on the spine is almost absent when turned (7 sec: right side relief / 15 sec: left side relief).
..So this is a very short insight to a long and thorough test. If you are interested in learning more about our findings or want to contribute to testing our technology, do not hesitate to get in touch!
