The prevention of pressure sores for patients with spinal cord injuries includes pressure relief through the patient shifting position and, thus, weight. We have designed a microprocessor-based device to mount on the seat of a conventional wheelchair. This device has applications in hospital rehabilitation programs for improving patient care and in research to study the cause and prevention of pressure sores. It can use audible alarms, which can be disarmed, to train patients to regularly shift weight. The device stores in its memory data on the interval between and the duration of weight shifts. The contents of this memory can be transmitted to a laboratory microcomputer system and displayed in tabular, graphical, or histogram formats. This device is more versatile than previous timer-based systems, not only because its timer and alarm parameters easily can be reprogrammed, but especially because it can store and play back detailed data on the patient's performance. The device is powered by rechargeable NiCad batteries, which can last several days without recharging.
脊髓损伤患者压疮的预防包括通过患者变换体位从而减轻体重来实现减压。我们设计了一种基于微处理器的装置，可安装在传统轮椅的座位上。该装置可应用于医院康复项目以改善患者护理，也可用于研究压疮的成因及预防。它能使用可解除警报的声音报警器来训练患者定期变换体重。该装置将体重变换的间隔时间和持续时间的数据存储在其内存中。这些内存内容可传输至实验室微型计算机系统，并以表格、图形或直方图格式显示。该装置比以往基于定时器的系统更具通用性，这不仅是因为其定时器和警报参数易于重新编程，更特别是因为它能存储并回放有关患者表现的详细数据。该装置由可充电镍镉电池供电，无需充电可持续使用数天。
