Body temperature holding device with heart rate and respiration rate detecting function for small animals and heart rate and respiration rate measuring system for small animals using the device

摘要

To provide a device for maintaining body temperature having heart rate and respiratory rate detection function for small animals and a heart rate and respiratory rate measurement system for small animals, which are capable of being simply and easily set up without causing the small animals pain. ;A sheet pressure-sensitive sensor (piezoelectric device or the like) (4) is provided over a flat-plate heater (1) to which a heater-current supplying line (2) is connected. The pressure-sensitive sensor (4) is sandwiched between thin insulation sheets (3). A spacer (6) formed of a metallic plate having a hole into which the pressure-sensitive sensor fits is provided between the thin insulation sheet (3, 3). A signal line (5) of the pressure-sensitive sensor (4) is connected to a control device and the heater-current supplying line (2) is connected to a power supply that is capable of being controlled by the control device. With this structure, it is possible not only to maintain the body temperature of a small animal but also to detect the heart rate and respiratory rate of the small animal placed on the pressure-sensitive sensor (4) with the pressure-sensitive sensor (4) and supply the detected values to the control device for measuring and monitoring the heart rate and respiratory rate of the small animal.
