A method of monitoring and analysing temperature distribution in a patient's bed during bed rest and sleep is described. The system consists of 16 temperature sensors, a solid-state recorder and a personal computer. The temperature sensors are attached on the surface of a bed mat. The temperature of the 16 measurement points are recorded and stored on a multichannel solid-state recorder, where a programmable read-only memory (PROM) is used as the memory device. The PROM is detachable from the recorder, and the temperature data is read by a computer. A two-dimensional temperature distribution pattern is obtained by interpolating the temperature between measured points. The system was effective for long-term temperature monitoring without patient discomfort, and it proved reliable and easy to use. The temperature distribution and changes in the distribution indicated body movement and hence periods of sleep.
描述了一种在患者卧床休息和睡眠期间监测和分析其床位温度分布的方法。该系统由16个温度传感器、一个固态记录器和一台个人计算机组成。温度传感器附着在床垫表面。16个测量点的温度被记录并存储在多通道固态记录器上，其中可编程只读存储器（PROM）用作存储设备。PROM可从记录器上拆卸下来，温度数据由计算机读取。通过对测量点之间的温度进行插值获得二维温度分布模式。该系统对于长期温度监测有效，且不会给患者带来不适，并且证明其可靠且易于使用。温度分布及其变化表明了身体的活动，从而显示出睡眠周期。
