[0012] When the present invention is used, the new non-contact infrared body temperature collector is set according to the design requirements and actual needs. First, the medical staff starts the power button, the electrical connector in the body temperature collector is connected to the external power supply, and the voltage is adjusted by the forward low-voltage dropout regulator to ensure the stability of the input voltage. During the charging process, the charging indicator light emitting diode LED3 lights up, and after charging is completed, the LED3 light emitting diode goes out; after starting the body temperature collector, a dialog box of "Please enter the operator account and password" pops up on the display module, and the medical staff enters their own HIS account and password according to the instructions to log in to the body temperature collection system; then, the patient information in the QR code on the patient's wristband or bedside card is identified by the information recognition module, and the body temperature is collected after the medical staff verifies that the patient information is correct; then, the collector lens end is aimed at the patient's temperature measurement part, and the temperature measurement trigger, that is, the button switch KEY1, is pressed to start the body temperature collector and measure the body temperature. During the measurement, the buzzer is turned on. The active buzzer FM in the circuit will make a "beep" sound, and the infrared body temperature acquisition module will start to collect body temperature. After the measured body temperature is processed by the multi-function power management SOC system-level chip, the body temperature will be displayed on the LCD display, that is, the display module in the circuit, including the patient's name, bed number, hospitalization number, body temperature, and temperature measurement time. The patient's body temperature will be broadcast through the speaker connected to the voice module, and the above information will be stored in the storage module; finally, after the medical staff confirms that the information is correct, they click on data upload, and the collected data and the executor's signature will be uploaded to the corresponding patient's electronic medical record in the HIS system (host computer) through the wireless communication module. If the upload fails due to poor network or other reasons, the medical staff can connect the power interface USB1 via a data cable to upload the collected data and the executor's signature to the corresponding patient's electronic medical record in the HIS system.

[0013] The storage module in the main control circuit system of the non-contact infrared body temperature collector of the present invention has the function of storing hundreds of data. Medical personnel can query the historical data of the patient's body temperature through the up key, i.e., the key switch KEY2 in the circuit, and the down key, i.e., the key switch KEY3 in the circuit.

[0014] The infrared body temperature acquisition module in this main control circuit system includes an optical focusing lens, a thermopile infrared temperature sensor, a signal amplifier, and an analog-to-digital converter (A / D conversion module). When the optical focusing lens of the body temperature collector is close to and aimed at the temperature measurement site, light of various wavelengths emitted from the human body is focused by the optical lens and filtered by a filter, leaving only infrared light. This infrared light irradiates and heats the thermopile, thereby generating a potential difference across the thermopile, that is, converting the optical signal into an electrical signal. The amplifier amplifies the electrical signal and converts it into a digital signal through analog-to-digital conversion (A / D conversion) or into a frequency signal through modulation and demodulation. Then, through compensation correction, parameter calibration, and algorithm modeling, it can be converted into a medical-grade high-precision temperature value, which is displayed on the liquid crystal display of the display module.

[0015] The ultrasonic ranging module in this main control circuit system uses a piezoelectric ceramic element to emit ultrasonic pulses. The sound waves triggered by this begin to propagate, then hit the object, reflecting and partially absorbing the sound waves. The ceramic element with the same voltage receives the reflected waves. The transmission time difference Δt between the transmitted wave and the received sound wave provides the distance between the body temperature collector and the patient, and accurate body temperature information is collected based on the optimal temperature measurement distance.

[0016] The voice module in this main control circuit system is connected to the speaker by a voice chip. The voice chip has a single-chip microcomputer core and can be repeatedly erased and burned, and can drive the speaker.

[0017] The storage module in the main control circuit system receives and stores the patient information, operator information and patient temperature collected by the information identification module and the body temperature acquisition module.

[0018] The wireless communication module in this main control circuit system transmits the data in the storage to the electronic medical record of the corresponding patient in the HIS system through the Internet of Things.

[0019] The present invention measures the patient's body temperature through infrared rays and stores the above data in a storage module. After the operation is completed, the patient information, body temperature data, operator name and other information are uploaded to the patient's medical record through the Internet of Things through the wireless communication module, and finally the patient's body temperature collection and entry are completed.

[0020] The non-contact infrared body temperature collector of the present invention is connected to the Internet of Things system. After the thermopile infrared sensor of the infrared body temperature collection module receives the energy emitted by the human body surface, it converts the infrared energy into an electrical signal. The amplifier amplifies the sensor electrical signal and converts it into a digital signal through analog-to-digital conversion (A / D conversion). Then, through single-chip microcomputer compensation correction, parameter calibration and algorithm model, it can be converted into a medical-grade high-precision temperature value. After the temperature measurement is completed, the Internet of Things system transmits its temperature data, patient information, and measurement personnel information to the HIS system (host computer) in real time.

[0021] The present invention utilizes the above-mentioned technical solutions. First, the contactless IC reader / writer in the information recognition module recognizes patient information stored in a QR code on a patient's wristband or bedside card. Second, the ultrasonic ranging module converts human body temperature into an electrical signal using an infrared electric push temperature sensor, which is then converted into a digital signal through analog-to-digital conversion, ultimately converting it into high-precision temperature data, completing the patient's body temperature acquisition. Third, after completing the temperature measurement, the main body temperature collector stores the temperature data, patient information, and operator information in a single-chip microcomputer. Historical data can also be accessed using the up and down keys, and the temperature measurement information can be uploaded to the HIS system. This effectively addresses the problem that existing temperature measurement devices in medical institutions cannot recognize patient information, store data after measurement, or upload information, and their structural design still has room for innovation and improvement. Actual operational test results have also demonstrated that the device has a novel and practical structure, can recognize patient information, accurately and quickly measure body temperature, automatically store temperature data, and promptly upload measured temperature information. It enables real-time monitoring of the temperature of both personnel and patients, and is easy to use. It is suitable for temperature measurement in medical institutions and other institutions.
