Description
Technical field
This utility model is related to technical field of medical instruments, specifically a kind of high-performance electronic clinical thermometer.
Background technology
Temperature signal is transformed into the signal of telecommunication by NTC sensor by electronic clinical thermometer, will measured through MCU signal processing
Temperature be displayed on liquid crystal display screen.Every kind of MCU has a stabilization time to NTC probe samplings, and such as conventional has 8 seconds/16
Second, when, in 8 seconds/16 seconds, rate of temperature change is less than 0.1 DEG C, MCU can provide buzzerphone, represent that measurement terminates to read survey
Value.
As shown in figure 1, common clinical thermometer NTC sensor 1 is sealed in inside steel bushing 3 by epoxy resin 2, steel bushing 3 is
Measurement head, 2 poor thermal conductivity of epoxy resin, pyroconductivity are low, and reasonable heat-conducting type epoxy resin thermal conductivity typically exists at present
1.0-1.5 (W/m.K, 25 DEG C), causes heat transfer rate slow, and heat balance time is long.
Based on above-mentioned situation, if measurement head pyroconductivity is low, heat balance time is long, and entrance MCU that can early is thermally-stabilised
Time, such as 37 degree of body temperature, when measuring 36.2 degree, because pyroconductivity is low, into heat-stable time, buzzer report
It is alert, cause measured value to be significantly less than actual body temperature value, so there is the low phenomenon of electronic clinical thermometer measured value, cause consumer
Generally believe that electronic clinical thermometer accuracy of measurement is low.So it is huge to improve measurement head conduction of heat meaning so as to MCU can be coordinated to realize
Body temperature is measured quick and precisely.
Utility model content
This utility model overcomes clinical thermometer poor thermal conductivity present in above-mentioned prior art, and the low technology of pyroconductivity is asked
Topic, there is provided a kind of good heat conductivity, heat balance time are short, can fast and accurately measure the high-performance electric daughter of human body temperature
Temperature meter.
What the technical solution of the utility model was realized in：
A kind of high-performance electronic clinical thermometer, including clinical thermometer body and the measurement head of clinical thermometer body head is arranged on,
Sensor is provided with measurement head, described sensor is fixed on measurement head inwall.
Preferably, described sensor is affixed on measurement head inwall by heat-conducting glue.Only using few inside measurement head
Amount fluid sealant is bondd with inwall, has both been saved glue, has been improve heat conductivility again.
Traditional two-wire system sensor is uncompensated, and anti-electromagnetic interference capability is poor；Preferably, also including heat conduction compensation
Block；Clinical thermometer is originally provided with wiring board in vivo, and sensor is connected with wiring board by lead, and a part for the lead is wrapped in be led
On thermal compensation block.Thus, conduction of heat of the sensor in measurement head is further improved, asking for sensor transmissions line compensation is solved
Topic, improves the ability of electromagnetism interference.
Lead is caused to disengage in order to prevent heat conduction compensation block from tampering, preferably, described heat conduction compensation block and measurement head
Clinical thermometer body head is fixed on by fluid sealant in the lump.
In order that more rule is stable；Preferably, lead is wound on heat conduction compensation block in a spiral form.
Coordinate with measurement head for convenience, preferably, heat conduction compensation block is cylinder.
Preferably, heat conduction compensation block is cellular ferrite.
Preferably, described sensor is NTC sensor.
The principle of the present utility model and beneficial effect for employing above-mentioned technical proposal be：
This utility model employs new packing forms, is directly fixed on sensor with the excellent heat-conducting glue of heat conductivility
On measurement head inwall, heat conductivility is greatly increased, mean coefficient of heat conductivity >=25 (W/m.K, 25 DEG C), and heat conductivility increases 10-20
Times, heat balance time is short, can fast and accurately measure human body temperature.
Further say, be also provided with a heat conduction compensation block, lead is wrapped on heat conduction compensation block with helical wire form, is entered
One step improves the capacity of heat transmission of measurement head, while compensating to lead transmission, further increases the anti-electromagnetism of sensor
The ability of interference.
