A study was carried out jointly by nursing staff and technologists in an attempt to develop a cushion based on scientific principles and measurement that might prevent pressure sores. At each stage in the development clinical trials were carried out, and using the results of these together with the opinions of medical staff and patients who used the cushion the design was suitably modified. Over four years a seat was evolved that was simple to construct and fulfilled the clinical requirements for a wide range of patients while providing maximum relief of high-pressure points. The design was subsequently taken up commercially.
一项由护理人员和技术专家联合开展的研究，旨在基于科学原理和测量方法开发一种可能预防压疮的坐垫。在开发的每个阶段都进行了临床试验，并结合这些试验结果以及使用该坐垫的医护人员和患者的意见对设计进行了适当修改。经过四年的时间，一款易于制作的座椅问世了，它满足了各类患者的临床需求，同时最大程度地缓解了高压点带来的不适。该设计随后投入了商业生产。
