Description

Infant forehead palm of the hand heat release heat measurement instrument

Technical field

This utility model relates to medical treatment and nursing Instrument technology field, is specifically related to a kind of infant forehead palm of the hand heat release heat measurement instrument。

Background technology

Traditional Chinese Medicine is thought: when the endogenous fire such as infant stomach-fire are bigger, its palm of the hand is bigger than Normal Infants with forehead heat。The astute heads of a family are according to this theoretical palm of the hand often paying close attention to child and forehead, once find heat, just adjust diet or simply allow child take the little medicine that keeps healthy, and child would not have a fever flu。But, how the forehead of child and the palm of the hand calculate heat？Heat drinks sweet mung bean soup to what situation？Until what time heat changes the clothes little medicine of point？The result of father and mother's sensation is just different, also everybody？The forehead of infant, feverish sensation over the palm, body temperature can not increase therewith, do not measure during with clinical thermometer, can only say that the body interior of infant produces amount of heat, distributed by the palm of the hand and forehead, in the hope of body heat balance, if the heads of a family be not concerned with or take measures improper, child's interior-heat does not dissipate not out, and next step will cat fever。

Utility model content

This utility model provides a kind of infant forehead palm of the hand heat release heat measurement instrument, to solve the problem that infant body heat cannot carry out accurately detection that prior art exists。

This utility model solves its technical problem and be the technical scheme is that

A kind of infant forehead palm of the hand heat release heat measurement instrument, it is made up of temperature transducer, circuit unit, LCD temperature and time display screen and hand holding handle, circuit unit includes amplifying circuit, A/D change-over circuit and CPU, temperature transducer is connected with the amplifying circuit of circuit unit by wire, amplifying circuit is connected with CPU by A/D change-over circuit, CPU is connected with the key device on LCD temperature and time display screen and hand holding handle respectively, and key device includes SR and on and off switch。

The operation principle of this utility model device is: temperature transducer adopts PT100 film platinum resistor, diaphragm type platinum resistance temperature sensor is the temperature sensor utilizing thin film technique to manufacture, and precision is high, good stability, in order to reduce the error that wire causes further, this device adopts four-wire measurement。Surveyed human body temperature parameter is transferred to circuit unit with electricity form by wire。Circuit unit includes amplifying circuit, A/D change-over circuit, timing circuit, CPU etc.。The faint small-signal of temperature transducer collection is amplified by amplifying circuit；Analog-signal transitions is digital quantity by A/D change-over circuit；Timing circuit completes to measure the time measurement of temperature stabilization times section from starting temperature。

This utility model can scientifically detect child's forehead in palm of the hand heat release heat, and the health evaluation for child provides practical foundation, has simple in construction, easy to use and detect advantage accurately。
