In many large hospitals, ICU wards or departments requiring real-time temperature monitoring often utilize temperature monitoring systems as a key component for temperature diagnosis.

[0003] Existing body temperature sensing components often use NTC thermistors to measure human body temperature. NTC thermistors are prone to accuracy errors, have a slow response speed, and take a long time to stabilize the temperature value. They cannot meet the accuracy, response speed, and temperature stabilization time requirements of body temperature sensing components required by medical staff. Utility Model Content

The heat conductor has a first surface and a second surface facing each other, the first surface being provided with the IC temperature sensor, and the second surface being provided for contact with the human body.

[0006] In one embodiment, the body temperature sensing component further includes a protective member, which covers the surface of the IC temperature sensor exposed to the heat conductive member.

[0007] In one embodiment, a portion of the protection member covers the surface of the IC temperature sensor exposed to the heat conductor, and another portion of the protection member covers at least a portion of the first surface of the heat conductor, so that the IC temperature sensor is disposed on the first surface of the heat conductor.

[0008] In one embodiment, the protective member is configured as a heat conductive member made of epoxy resin.

[0009] In one embodiment, the wiring harness is a single-shield wiring harness.

[0010] In one embodiment, the wiring harness includes an outer sheath, a shielding layer, and a wire, which are sequentially arranged from the outside to the inside.

[0023] like Figure 1-3The present application provides a body temperature sensing component that can be used to measure the body temperature of a human body surface. The body temperature sensing component includes an IC temperature sensor 10, a wiring harness 20, a connecting plug 30, and a heat conducting member 40.

[0024] One end of the wiring harness 20 is electrically connected to the IC temperature sensor 10, specifically to a pin on the IC temperature sensor 10. A connector plug 30 is electrically connected to the other end of the wiring harness 20. Specifically, the connector plug 30 may be connected to an electrode terminal provided on the connector plug 30. The connector plug 30 is used to connect to a monitoring device to transmit the temperature signal measured by the IC temperature sensor 10 to the monitoring device. The monitoring device processes the temperature signal and outputs the measured body temperature on a display, allowing medical personnel to diagnose the patient based on the measurement results.

[0025] The heat conductor 40 has a first surface 41 and a second surface relative to each other. The first surface 41 is provided with the IC temperature sensor 10, and the second surface is used for contacting the human body. The first surface 41 of the heat conductor 40 is used to fix the IC temperature sensor 10. The heat conductor 40 can be fixedly connected to the wiring harness 20 to ensure the stability of the IC temperature sensor 10. The second surface of the heat conductor 40 can ensure that the body temperature sensing component is well fitted with the human body surface when measuring the human body surface temperature, which is convenient for measurement. The heat conductor 40 can be made of a material with high thermal conductivity efficiency to prevent the heat loss of the heat conductor 40 during heat transfer from being high, resulting in inaccurate temperature measurement. For example, in one embodiment, the heat conductor 40 is configured as a metal heat conductor 40. The metal material can be 304 stainless steel, which has strong corrosion resistance and is easy to clean and disinfect during use, greatly improving the durability and service life of the body temperature sensing component.

[0026] The body temperature sensing component of the present application uses an IC temperature sensor 10 to measure human body temperature. The IC temperature sensor 10 integrates an analog-to-digital converter (ADC) and digital signal processing circuitry, allowing for digitized temperature processing. It is typically factory-calibrated to correct temperature readings and improve accuracy. Compared to existing NTC thermistors, IC temperature sensors typically have a linear output, making them easier to calibrate and accurately calculate. The IC temperature sensor 10 provides a digital output rather than an analog output, communicating via a digital interface (such as I2C or SPI), reducing noise and distortion that may be introduced during analog signal transmission. NTC thermistors typically require external circuitry for signal conditioning and conversion, which can introduce some uncertainty and additional errors. The IC temperature sensor 10 used in the present application is an integrated circuit for temperature measurement with adjustable sensitivity and calibration coefficients. The IC temperature sensor 10 offers highly accurate, low-power temperature measurement, excellent accuracy of ±0.1K, and high thermal conductivity, providing more accurate, precise, and rapid temperature measurement with shorter temperature stabilization times.

[0027] In one embodiment, the heat conductor 40 is in the shape of a disk or a sheet. The disk-shaped or sheet-shaped heat conductor 40 facilitates the second surface of the heat conductor 40 to fit well on the human body surface, which is beneficial to improving the accuracy of measurement.

[0028] In one embodiment, the body temperature sensing component further includes a protective member 50, which covers the surface of the IC temperature sensor 10 exposed to the heat conductive member 40. By covering the surface of the IC temperature sensor 10 exposed to the heat conductive member 40 with the protective member 50, the IC temperature sensor 10 can be effectively protected, thereby effectively ensuring the reliability, pressure resistance, and service life of the body temperature sensing component.

[0029] In one embodiment, the protective member 50 is configured as a thermally conductive member 40 made of epoxy resin. Medical-grade epoxy resin can be used, which is inherently non-toxic, can be sterilized at high temperatures, and does not volatilize toxic substances, meeting the requirements of medical materials GB14233.1 and GB16886.1. Furthermore, after curing, the high hardness of the epoxy resin effectively protects the IC temperature sensor.

[0030] In one embodiment, a portion of the protective member 50 covers the surface of the IC temperature sensor 10 exposed from the thermal conductor 40, and another portion of the protective member 50 covers at least a portion of the first surface 41 of the thermal conductor 40, thereby positioning the IC temperature sensor 10 on the first surface 41 of the thermal conductor 40. In other words, the protective member 50 also serves to secure the thermal conductor 40 and the IC temperature sensor 10 together. The protective member 50 may secure the thermal conductor 40 and the IC temperature sensor 10 together by vulcanization.

[0031] In one embodiment, the wiring harness 20 is a single-shielded wiring harness 20. Furthermore, the wiring harness 20 includes a jacket, a shielding layer, and wires, which are arranged in sequence from the outside to the inside. One end of the wire is electrically connected to the IC temperature sensor 10, and the other end of the wire is electrically connected to the connector 30. By using a single-shielded wiring harness 20 with strong anti-interference properties, it can shield against ionic interference from other devices and accurately transmit signals.

[0032] In one embodiment, if Figure 1 and Figure 2 As shown, the connecting plug 30 has a plug portion 31, which is used to connect to the socket of the monitoring device. The side walls of the plug portion 31 have protrusions 311 and / or grooves, and the socket corresponds to the structure of the plug portion 31, so that when the plug portion 31 is plugged into the socket, there is only one positive plugging direction. By providing the protrusions 311 and / or grooves on the side walls of the plug portion 31, there is only one positive plugging direction when the plug portion 31 is connected to the socket. This can prevent the connecting plug 30 from being inserted backward, causing the body temperature sensor component to be unusable, and has an excellent fool-proof design. The PIN pins of the connecting plug 30 can be made of brass with a gold-plated surface, which can effectively ensure signal transmission performance. In addition, the plug portion 31 can also be provided with a self-locking function to improve the reliability of the body temperature sensor component, so that the stability of the signal is guaranteed when the body temperature sensor component is connected to the monitoring device.

[0033] The present application also provides a body temperature monitoring system, comprising a body temperature sensing component and a monitoring device, wherein the body temperature sensing component is the body temperature sensing component involved in any of the above embodiments. The monitoring device is used to be electrically connected to the body temperature sensing component to obtain body temperature information collected by the body temperature sensing component.

[0034] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
