TEMPERATURE, PULSE AND RESPIRATION DETECTION APPARATUS

摘要

A temperature, pulse and respiration detector having a non-disposable sensor and a disposable cover. The sensor comprises a probe having a thermistor mounted at one end for insertion into the body to sense temperature. The sensor also comprises a thermistor spaced from the end of the probe and housed within the body of the sensor for sensing respiration. Pulse is sensed by a photoelectric detector mounted in the sensor body. The disposable cover has at least one opening which associates with the respiration-sensing thermistor so that the thermistor is exposed to respiration and at least one radiation transmitting portion which associates with the photoelectric detector. In normal use, the patient places the probe in his mouth while holding the sensor in his hand so that his finger is over the photoelectric detector. The patient's temperature is sensed by the thermistor in his mouth, his respiration by the respiration-sensing thermistor in the sensor body and his pulse rate derived from the changes in the radiation transmission characteristics of his finger sensed by the photoelectric detector.
