在医疗和护理中，需要测量体温来进行日常健康管理。特别是，它对于预防脊髓损伤患者的体温调节失败和早期发现卧床老人的肺炎的重要性已得到充分认识。然而，市售的腋下和口腔温度计对于此类患者以及操作这些设备的护理人员来说都很麻烦，因为需要将生物传感器连接到患者的身体上。本文描述了开发非侵入式体温测量系统的新尝试。当护理人员帮助患者改变姿势以防止压疮时，当床单与患者身体接触时会测量温度。在该方法中，三个传感器模块（每个模块包含热敏电阻、电阻敏感压力传感器和隔热材料）安装在床单中，并位于受试者的左肩胛骨、腹腔神经丛和腰部下方。可以根据压力传感器检测到受检者躺在床上后立即升温的速率变化来估计体温。从原型床系统获得的体温与市售腋窝温度计测量的 9 名成年人（20-98 岁）的体温进行比较，表明所提出的方法可能对体温测量有用。然而，为了详细、持续地分析健康状况，需要改进传感器模块的定位。
In medical and nursing care, body temperature measurement is required for daily health management. In particular, its importance has been well-recognized for the prevention of thermoregulatory failure in patients with spinal cord injuries and for early detection of pneumonia in bedridden elderly. However, commercially available axillary and oral thermometers are cumbersome for such patients as well as for the care staff who operates the devices, because of the need to attach the biological sensor to the patient’s body. This paper describes a new attempt at developing a non-intrusive system for measuring body temperature. While the care staff helps the patient change posture to prevent pressure ulcers, temperature is measured when the bed sheet makes contact with the subject’s body. In this method, three sensor modules, each comprising a thermistor, a resistance-sensitive pressure sensor and a heat insulating material, are installed in the bed sheet and positioned under the subject’s left scapula, celiac plexus, and waist. The body temperature can be estimated from the rate variation of temperature increase immediately after the pressure sensor detects that the subject has laid down on the bed. Comparison of the body temperature obtained from the prototype bed system and that measured by a commercially available axillary thermometer in nine adults (aged 20-98 years) demonstrated that the proposed method may be useful for body temperature measurement. However, improvement in positioning the sensor modules is needed for detailed and continuous analysis of health condition.
