Description
Technical field
The utility model relates to measurement of bldy temperature field, in particular to a kind of ear of the thermistor-type of continuous measurement body temperature
Machine.
Background technique
Body temperature is that the most basic of people is also most important vital sign, and the body temperature of Healthy People is relative constant.Human body
Central temperature is in pulmonary artery position, since this temperature spot is in inside of human body, therefore, it is impossible to carry out actual measurement.In day
Often using upper, the measurement point closest to central temperature is to take second place to be in anus in oral cavity, followed by oxter.Ear-drum is near brain
One internal temperature measuring point of hypophysis theoretically and is closer to the point of human body central temperature, since the point cannot be using contact
Formula clinical thermometer directly measures, and therefore, the past clinically seldom uses.
Currently, medical body temperature measuring instrument is divided into two major classes, respectively mercury clinical thermometer and electronic thermometer, mercury body temperature
Meter has faced comprehensive disabling due to security reason.
Existing electronic thermometer is divided into contact and two kinds contactless, and contact-type electronic clinical thermometer generally uses temperature-sensitive
Resistance measurement, for measuring in anus, the body temperature of in mouth and oxter.Since in anus and oral cavity easily causes cross-infection, face
It is more on bed not use the two measurement points.Transaxillary position is easy to measure, but needs to be in close contact, and time-consuming, therefore for children
It is relatively difficult with patient's measurement in critically ill patient and operation.Contactless electronic clinical thermometer generally uses far infrared thermometric
Technology, measurement position are forehead and ear-drum.Advantage is that time of measuring is short (1-2 seconds), the disadvantage is that environment temperature when instrument works
It is required that harsh (16-40 DEG C), patient's surrounding enviroment factor is also affected to measurement result when measurement, in environment temperature and human body
Continuous work is unable to when temperature difference is larger.Therefore, clinically it is chiefly used in carrying out fever patient primary screening, doctor's root again
Judged according to experience.
