Description
Decubitus is caused by unchangeable sitting postures for durable times. Especially immobile people are very sensitive to decubitus. Unchanging pressure points, shear forces and a weak tissue will develop wounds. By alternating the pressure points, the veins have time to recover themselves, thus stimulating the blood-flow and the healing process.
The seating system is an anti-decubitus cushion with an alternating pressure system (pump-unit).

 

Rows of bellows into the cushion alternately inflate and deflate with air.
A short term solution is developed with an improved pump which is smaller, lighter and cheaper as the previous version. Also a future system is developed in which the pump is integrated in the cushion.
