Description

Technical Field

[0001] This invention relates to the field of temperature recognition and compensation technology, and in particular to a patch-type body temperature measurement method, system, device, and medium for compensating impedance. Background Technology

[0002] Traditional body temperature measurement mainly uses mercury thermometers and infrared thermometers. Both of these temperature measurement tools have drawbacks to varying degrees, such as long measurement time, large measurement error, and the temperature measurement results being significantly affected by ambient temperature.

[0003] Electrostatic temperature measurement is a new method for measuring human body temperature. It uses a thermistor whose resistance changes with temperature to sense human body temperature, and the actual body temperature can be calculated by measuring the resistance of the thermistor.

[0004] However, during the manufacturing process, thermistors may have resistance deviations due to manufacturing issues. This results in different resistance changes with temperature, meaning the relationship between resistance and temperature varies. Since the body temperature patch cannot identify these resistance deviations and perform corresponding impedance compensation, body temperature measurement based on thermistors still has some errors, leading to inaccurate temperature measurements. Summary of the Invention

[0005] In view of this, embodiments of the present invention provide a patch-type body temperature measurement method, system, device, and medium for compensating impedance.

[0006] The first aspect of the present invention provides a patch-type body temperature measurement method with compensated impedance, applied to a body temperature measurement system including a body temperature patch and a host, wherein a thermistor and a sorting resistor are installed in the body temperature patch; the resistance value of the thermistor can change from an initial resistance value to a measurement resistance value corresponding to the specified temperature at different specified temperatures.

[0007] The method includes the following steps:

[0008] After the body temperature patch is applied to the designated location of the target object, the measured resistance value of the thermistor and the marked resistance value of the sorting resistor are obtained.

[0009] The type of thermistor is identified by the marked resistance value of the sorting resistor;

[0010] The actual temperature of the target object is obtained by performing compensation calculations based on the measured resistance value and the type of the thermistor.

[0011] Furthermore, the initial resistance value of the thermistor refers to the resistance value exhibited by the thermistor at the first temperature; the type of the thermistor is determined during the production process of the body temperature patch through the following steps:

[0012] The thermistor is heated or cooled to a first temperature, and the initial resistance value of the thermistor is determined at the first temperature.

[0013] Obtain a preset initial resistance range, divide the initial resistance range into several resistance intervals with equal resistance intervals, and assign an interval number to each resistance interval.

[0014] The initial resistance value of the thermistor is determined to be within a resistance range, which is then defined as the first resistance range. The type of the thermistor is determined by the range number of the first resistance range.

[0015] Furthermore, the marked resistance value of the sorting resistor installed on the body temperature patch is determined during the production process of the body temperature patch through the following steps:

[0017] Determine the marked resistance value corresponding to the category of the thermistor installed on the body temperature patch, and install the resistor with the marked resistance value as a sorting resistor on the body temperature patch.

[0018] Furthermore, the compensation calculation based on the measured resistance value of the thermistor and the type of the thermistor specifically includes the following steps:

[0019] The compensation resistance of the thermistor is calculated using the following formula:

[0020] ω=ω0-c×Δω

[0021] In the formula, ω represents the compensation resistance, ω0 represents the measured resistance, c represents the type of thermistor, and Δω represents the resistance interval of the initial resistance range.

[0022] Obtain a preset resistance-temperature correspondence table, and select the temperature value that is closest to the compensation resistance value as the actual human body temperature output.

[0023] Furthermore, the specified temperature range is 25.0℃ to 45.0℃; the initial resistance of the thermistor ranges from 29614Ω to 30264Ω.

[0024] The second aspect of this invention discloses a body temperature measurement system, including a body temperature patch and a main unit; the body temperature patch is further provided with conductive leads and a pin contact point, and the thermistor and the sorting resistor are electrically connected to the pin contact point respectively through the conductive leads;

[0025] The main unit includes a control circuit, a resistance detection circuit, a power supply circuit, and a pin. The resistance detection circuit is electrically connected to the pin, and the resistance detection circuit and the power supply circuit are respectively electrically connected to the control circuit.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] Common body temperature patches are disposable. The patch contains a temperature sensor, including a thermistor, and displays the target's real-time body temperature via a digital display or remote terminal. The patch is discarded after use. Compared to mercury or infrared thermometers, body temperature patches offer advantages such as ease of wear, high accuracy, and good sealing. However, the temperature measured by thermistors is strongly correlated with the initial resistance value of the thermistor. Due to manufacturing processes and other factors, the thermistor's resistance can deviate during production, leading to measurement errors. Current body temperature patches typically have a measurement error of ±0.5℃, indicating significant room for improvement.

[0042] See Figure 1 This invention provides a patch-type body temperature measurement method with impedance compensation, applied to a body temperature measurement system including a body temperature patch and a main unit. The body temperature patch of the body temperature measurement system is equipped with a thermistor and a sorting resistor; the resistance value of the thermistor can change from an initial resistance value to a measurement resistance value corresponding to a specified temperature at different specified temperatures. Specific methods for installing the thermistor and sorting resistor include surface mounting, through-hole mounting, and mixed mounting. Surface mounting refers to applying solder paste to the body temperature patch and then fixing the resistor on the patch using processes such as reflow soldering; through-hole mounting refers to manually inserting the resistor into a fixed position on the patch; mixed mounting refers to simultaneously using surface mounting and through-hole mounting methods to install the thermistor and sorting resistor.

[0043] The body temperature measurement method in this embodiment includes the following steps:

[0044] S101. After the body temperature patch is applied to the designated position of the target object, obtain the measured resistance value of the thermistor and the marked resistance value of the sorting resistor;

[0045] S102. Identify the type of thermistor by the marked resistance value of the sorting resistor;

[0046] S103. Perform compensation calculations based on the measured resistance value and the type of thermistor to obtain the actual temperature of the target object.

[0047] The patch-type body temperature measurement method provided in this embodiment of the invention uses a sorting resistor on the body temperature patch that corresponds to the type of thermistor. This allows the body temperature measurement system to identify the type of thermistor by obtaining the resistance value of the sorting resistor. Based on the identified thermistor type and the obtained thermistor resistance value, a compensation calculation is performed to obtain the actual measured resistance value. The actual measured resistance value is then converted into the actual temperature of the target object, thereby improving the accuracy of body temperature patch temperature measurement.

[0048] For example, the thermistor used in this embodiment is an NTC (Negative Temperature Coefficient) thermistor. NTC thermistors and PTC (Positive Temperature Coefficient) thermistors are two types of thermistors. The resistance of an NTC thermistor decreases as temperature increases, while the resistance of a PTC thermistor increases with temperature. Because NTC thermistors are more sensitive to temperature changes over a small range than PTC thermistors, this embodiment uses an NTC thermistor for human body temperature measurement.

[0049] The body temperature patch structure used in this embodiment differs from existing body temperature patches. The main difference is that, in addition to the thermistor, a sorting resistor for temperature compensation is also provided. Figure 2 The diagram shows the production process of the body temperature measurement system patch according to an embodiment of the present invention. After the production of the thermistors is completed, the thermistors are divided into multiple categories according to their initial resistance values. For each category of thermistor, a sorting resistor with a corresponding marked resistance value is matched and installed on the body temperature patch.

[0050] The initial resistance of a thermistor refers to the resistance value exhibited by the thermistor at the first temperature; the type of thermistor is determined during the production process of the body temperature patch through the following steps:

[0051] S201. Heating or cooling the thermistor to a first temperature, and determining the initial resistance value of the thermistor at the first temperature;

[0052] S202. Obtain the preset initial resistance range, divide the initial resistance range into several resistance intervals with equal resistance intervals, and assign an interval number to each resistance interval.

[0053] S203. Determine the resistance range in which the initial resistance value of the thermistor is located as the first resistance range, and determine the type of the thermistor by the range number of the first resistance range.

[0054] In this embodiment, the first temperature is set to 37℃. The resistance interval is set to 30Ω. Based on the relevant experimental data of the initial resistance value of the thermistors, the thermistors are divided into 21 categories as shown in Table 1:

[0055]

[0056] For example, if a thermistor exhibits an initial resistance of 30.000 kΩ after being heated to 37°C, then this thermistor would be classified as Class 5. The thermistors produced in this embodiment can be used for temperature measurement in the range of 25.0°C to 45.0°C. Experimental data shows that most of the produced thermistors fall within the range of Class 0 to Class 5, with the maximum deviation not lower than 29.614 kΩ for Class -7 and higher than 30.264 kΩ for Class 13.

[0057] After determining the category of each thermistor, this embodiment indicates the thermistor category by installing a sorting resistor on the temperature patch. The resistance value of the sorting resistor can be sensed by the sorting resistor value detection circuit of the temperature measurement system host, thereby identifying the thermistor category. Since the sorting resistor in this invention serves to mark the thermistor category on the patch, other methods can be used to indicate the thermistor category to the host, such as using a capacitor with a specific farad. Magnetic strips, QR codes, etc., can also be used to record the thermistor category, but corresponding reading devices need to be configured on the temperature measurement system host. Experiments show that using a sorting resistor as the thermistor category marking method is the lowest production cost method.

[0058] In this embodiment, the resistance value of the sorting resistor mark installed on the body temperature patch is determined during the production process of the body temperature patch through the following steps:

[0059] S301. For each type of thermistor, a marked resistance value is assigned to represent that type, and the marked resistance values ​​are different from each other;

[0060] S302. Determine the marked resistance value corresponding to the category of the thermistor installed on the body temperature patch, and install the resistor with the marked resistance value as a sorting resistor on the body temperature patch.

[0061] In this embodiment, the marked resistance value of the sorting resistor can be independent of parameters such as resistance range and resistance interval. Since the sorting resistor value detection circuit needs to confirm the resistance value of the sorting resistor through current input, the marked resistance value can be set to a value with low energy consumption and obvious resistance differentiation, such as 100Ω, 150Ω...1050Ω, etc., represented by an arithmetic sequence.

[0062] In this embodiment, S103 performs compensation calculations based on the measured resistance value and the type of thermistor, specifically including the following steps:

[0063] S103-1. Calculate the compensation resistance of the thermistor using the following formula:

[0064] ω=ω0-c×Δω

[0065] In the formula, ω represents the compensation resistance, ω0 represents the measured resistance, c represents the type of thermistor, and Δω represents the resistance interval of the initial resistance range.

[0066] S103-2. Obtain the preset resistance-temperature correspondence table, and select the temperature value that is closest to the compensation resistance value as the actual human body temperature output.

[0067] In step S103, after determining the type of thermistor by the marked resistance value of the sorting resistor, the required compensation resistance value for the thermistor on this body temperature patch is calculated using the above formula. For example, a body temperature patch with a thermistor having an initial resistance of 30.000kΩ is used to measure human body temperature. The measured resistance is 29700Ω. The calculated compensation resistance value is ω = 29700 - 5 × 30 = 29550Ω. By using 29550Ω as the search condition to consult the preset resistance-temperature correspondence table, the required actual human body temperature value can be obtained.

[0068] It is readily apparent that when the initial resistance of the thermistor is at a low value (-1 to -7), the product of category c and resistance interval Δω will be compensated according to the corresponding category; when the initial resistance of the thermistor is at a high value (1 to 13), the product of category c and resistance interval Δω will be deducted according to the corresponding category; ultimately, the compensated resistance ω is kept at a relatively stable level. This embodiment, by introducing resistance compensation calculations for the thermistor, can balance the initial resistance error caused by manufacturing process errors, ensuring that the calculated compensated resistance value is generally close regardless of the initial resistance value, further improving the temperature measurement accuracy of the body temperature measurement system. Experimental data shows that the temperature measurement accuracy of this embodiment reaches ±0.01℃, significantly better than the ±0.5℃ of the prior art.

In this embodiment of the body temperature measurement system, the body temperature patch, in addition to a thermistor and a sorting resistor, also has conductive leads and a pin contact point; the thermistor and the sorting resistor are electrically connected to the pin contact point via the conductive leads. Compared to common body temperature patches, the body temperature patch in this embodiment has fewer mounting components, therefore it is lighter and easier to wear.

[0070] See Figure 4 The main unit includes a control circuit, a resistance detection circuit, a power supply circuit, and a probe. The resistance detection circuit is electrically connected to the probe, which obtains the resistance values ​​of the thermistor and sorting resistor on the temperature patch.

In some embodiments, the host also includes a voice broadcast circuit, which is electrically connected to the control circuit. After the control circuit calculates the actual human body temperature, it broadcasts the calculated temperature via the voice broadcast circuit. In another embodiment, the body temperature measurement system also includes a terminal with a display screen, and the host also includes a wireless communication circuit, which is electrically connected to the control circuit. The control circuit transmits the calculated actual human body temperature to the terminal and displays it on the display screen via the wireless communication circuit. In yet another embodiment, the host also includes a display screen, which is electrically connected to the control circuit. The control circuit transmits the actual human body temperature to the display screen for display.
