Problems solved by technology

[0002] Babies under the age of three basically do not have cognitive ability, so in order to avoid danger when they are sick and need to measure body temperature, oral surface mercury thermometers cannot be used; mercury thermometers can only be placed in the armpit or anus, and the thermometer is placed under the armpit. The temperature is often not accurate enough, the comfort is poor when placed in the anus, and the baby is easy to resist, which is not conducive to the normal measurement
[0003] Now there is also a non-contact infrared thermometer that can measure body temperature by irradiating the eardrum. However, due to the characteristics of infrared radiation measurement, the distance between the probe of the thermometer and the eardrum is different every time the measurement is performed, resulting in inaccurate measurement results. affect the doctor's diagnosis

Embodiment 1

[0015] Example 1: Reference figure 1 , the high-precision thermometer of the present invention includes a body 1, a probe 3 is provided at the front end of the body 1, a filter 2 is provided on the probe 3, and a movably connected retaining ring 4 is also provided on the probe 3, and the retaining ring 4 can be pivoted on the probe 3. The retaining ring 4 is provided with radially evenly distributed screw holes, and screws are arranged in the screw holes for fixing the position on the probe 3 of the retaining ring 4. Near the bottom of the probe 3, a filter infrared emitter 6 and Filter infrared detector 5; the front of the middle part of the body 1 is provided with a display screen 7 and a switch button 8, the side of the middle part of the body 1 is provided with a temperature sensor 9, and the filter infrared detector 5 is sequentially connected to the main control IC, analog signal amplification circuit, and filter circuit and the A / D circuit, the A / D circuit and the tempe...

Embodiment 2

[0017] Example 2: Reference figure 1 , On the basis of Embodiment 1, the battery of the ear thermometer is connected to the power measurement circuit, and the power measurement circuit is connected to the low battery alarm module and the microprocessor. When the battery power is insufficient, the temperature measurement will not be performed, and a reminder will be issued to remind the user to charge the battery or replace the battery.

Embodiment 3

[0018] Example 3: Reference figure 1 , On the basis of Embodiment 1 or 2, the microprocessor is connected to the data storage module, and the data storage module is connected to the display screen; the body 1 is provided with a USB data line slot, and the USB data line slot is connected to the data storage module. Past data can be displayed and printed for reference by doctors.

Abstract

The invention discloses a high precision clinical thermometer comprising a thermometer body. The front end of the thermometer body is provided with a probe, the probe is provided with a filter and is movably provided with a baffling ring, and the bottom of the probe is provided with a filter infrared emitter and a filter infrared detector; the middle of the front surface of the thermometer body is provided with a display screen and a switch button, and the middle of the side of the thermometer body is provided with a temperature sensor; the filter infrared detector is connected to a main control IC, an analog signal amplifying circuit, a filter circuit and an A / D circuit sequentially, the A / D circuit is connected to a temperature sensor connected to a micro processor, and the micro processor is provided with a correction module used for correcting the temperature measured by the filter infrared detector when the temperature measured by the temperature sensor and the standard temperature of the thermometer body are different. The thermometer is capable of measuring the temperature of an infant conveniently, and the measurement result is precise.
