Abstract
The invention discloses a high-precision temperature measure instrument which comprises a body. A probe is arranged at a far end of the body, an infrared temperature sensing unit and a position sensing light source are arranged on the probe, a display screen and a switch button are arranged on the front face of the body, the infrared temperature sensing unit is sequentially connected with a master control IC, an analog signal amplification circuit, a filter circuit and an A/D circuit, and the A/D circuit is connected with a microprocessor. A temperature sensor is arranged on the back face of the near end of the body and connected with the microprocessor, and a rectification module is arranged on the microprocessor and used for rectifying the temperature measured by the infrared temperature sensing unit when the temperature measured by the temperature sensor is different from a set standard temperature value of a thermometer. The high-precision temperature measure instrument can measure the temperature of infants conveniently, and the measured results are accurate.
Description
Technical field
The present invention relates to a kind of high accuracy body temperature measuring instrument.
Background technology
Baby below three one full year of life does not possess cognitive competence substantially, thus when sick need take temperature time in order to avoid danger, oral thermometer mercury clinical thermometer can not be used; Mercury clinical thermometer can only be placed in oxter or anus, and clinical thermometer is placed on oxter, measures the temperature that obtains often not accurate enough, and when being placed on anus, comfortableness is poor, and baby is easy to resistance, and what be unfavorable for measuring normally carries out.
Also there is a kind of contactless infrared thermometer now, can by irradiating eardrum position take temperature, but due to the feature of infrared radiation measurement, when measuring at every turn the probe of clinical thermometer and the distance of eardrum all different, cause the result of measurement inaccurate, affect the diagnosis of doctor, and the eardrum of baby is thinner tender, neglectful maloperation probably damages the eardrum of baby.
Summary of the invention
The object of this invention is to provide a kind of high accuracy body temperature measuring instrument, can carry out the measurement of bldy temperature of baby easily, measurement result is accurate.
For achieving the above object, the technical scheme that one embodiment of the present of invention are taked is:
Comprise body, body distal end is provided with probe, probe is provided with infrared temperature sensing unit and location sensitive light source, body front is provided with display screen and shift knob, infrared temperature sensing unit connects master control IC, amplifying circuit of analog signal, filter circuit and A/D circuit successively, and described A/D circuit connects microprocessor.The body proximal end back side is provided with temperature sensor, temperature sensor connects microprocessor, microprocessor is provided with correction module, when the standard temperature value that the temperature recorded and thermometer set has a deviation, calibrates the temperature that infrared temperature sensing unit records for Tc sensor.
Preferably, body is provided with battery, and described battery connects electric quantity of power supply measuring circuit, and electric quantity of power supply measuring circuit connects low electricity alarm module and microprocessor.
The beneficial effect that high accuracy body temperature measuring instrument of the present invention produces is:
1. body distal end is provided with probe, and probe is provided with location sensitive light source, and gauger can be made when measuring to aim at the distance of measuring point and adjustment probe and measuring point accurately, and measurement result is more accurate.
2. when electricity is not enough, can affect the accuracy of measurement result, therefore, arrange battery and connect electric quantity of power supply measuring circuit, electric quantity of power supply measuring circuit connects low electricity alarm module and microprocessor.When battery electric quantity is not enough, does not carry out the measurement of body temperature, and send prompting, remind user of service to battery charging or change battery.
3. the body proximal end back side is provided with temperature sensor, temperature sensor connects microprocessor, microprocessor is provided with correction module, when the standard temperature value that the temperature recorded and thermometer set has a deviation, calibrates the temperature that infrared temperature sensing unit records for Tc sensor.
Accompanying drawing explanation
Figure 1 shows that the schematic diagram of an embodiment of a kind of high accuracy body temperature measuring instrument of the present invention.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with the specific embodiment of the invention and corresponding accompanying drawing, technical solution of the present invention is clearly and completely described.
Embodiment 1: with reference to figure 1, high accuracy body temperature measuring instrument of the present invention comprises body 1, body 1 far-end is provided with probe 5, probe 5 is provided with infrared temperature sensing unit and location sensitive light source, body 1 front is provided with display screen 4 and shift knob 2, infrared temperature sensing unit connects master control IC, amplifying circuit of analog signal, filter circuit and A/D circuit successively, and described A/D circuit connects microprocessor.
Embodiment 2: with reference to figure 1, on the basis of embodiment 1, the body 1 near-end back side is provided with temperature sensor 7, temperature sensor 7 connects microprocessor, microprocessor is provided with correction module, when the standard temperature value that the temperature recorded for Tc sensor and thermometer set has a deviation, the temperature that infrared temperature sensing unit records is calibrated.
Embodiment 3: with reference to figure 1, on the basis of embodiment 1 or 2, the battery of high accuracy body temperature measuring instrument connects electric quantity of power supply measuring circuit, and electric quantity of power supply measuring circuit connects low electricity alarm module and microprocessor.When battery electric quantity is not enough, does not carry out the measurement of body temperature, and send prompting, remind user of service to battery charging or change battery.
Embodiment 4: with reference to figure 1, on the basis of embodiment 1 or 2 or 3, microprocessor connection data memory module, data memory module connects display screen 4; Body 1 is provided with USB data line slot and function key 3, USB data line slot connection data memory module, microprocessor is by the data genaration trend curve of data memory module, show on the display screen 4 or printed by printer, understand baby's Temperature changing trend, do diagnosis reference for doctor.How many doctors, when seeing fever patient, it is of concern that temperature trend, instead of spends, now so after fever, can record the body temperature recorded at set intervals, so that doctor can grasp the state of an illness more rapidly and accurately.
Embodiment 5: with reference to figure 1, on any one basis of embodiment 1 ~ 4, body 1 is provided with sound switch button 6, when baby sleep soundly, button is placed in mute state, carries out measurement of bldy temperature to baby, can not affect the sleep of baby.
High accuracy body temperature measuring instrument of the present invention holds easy to operate and quick and convenient, only needs the head of thermometer to aim at forehead, just can in seconds, readout value.Thermometric does not need plug to baby's ear, crying and screaming of baby can not be caused disorderly dynamic, more do not need the protective sleeve changing probe, simple and convenient more effective.
Display screen 4 screen display color can help the body temperature determining baby: green representative is normal, and not have to generate heat, yellow has slight fever, redness is high temperature.
Above-mentioned embodiment is used for explaining and the present invention is described, instead of limits the invention, and in the protection domain of spirit of the present invention and claim, any amendment make the present invention and change, all fall into protection scope of the present invention.
