Description

Technical Field

[0001] The present application relates to the technical field of medical detection equipment, and in particular to a dynamic temperature measuring device for a dry biochemical analyzer. Background Art

[0002] A dry biochemical analyzer is an analyzer that uses solid phase carrier reagents for clinical chemistry tests. It quantitatively measures the concentration of specific components in a sample by reflectance photometry. The principle of a dry biochemical analyzer is to add a body fluid sample (serum, urine, etc.) to a dry reagent sheet, and the analyte in the sample reacts biochemically with the components of the reagent sheet, causing the color of the reagent sheet to change. After adding the sample, the reflected light density of the reagent sheet at a specific wavelength is periodically measured within a fixed reaction time, and finally a reaction curve of the sample over the entire reaction time is drawn.

[0003] To ensure that the analyte in the sample can fully react with the components of the reagent sheet, the reagent sheet needs to reach a temperature range of 37±0.2℃. In addition, during the whole machine test of the dry biochemical analyzer, the reagent sheet needs to be illuminated by a specific light source excited by the optical module to measure the reflected light density of a specific wavelength. Therefore, for a dry biochemical analyzer with a fixed photometric position, the reagent sheet needs to be moved to the photometric position for photometry. Since there is a certain difference in the temperature of the reagent sheet when the incubation tray is in a static state and a rotating state, in order to simulate the temperature change of the reagent sheet during the rotation of the incubation tray, it is necessary to measure the dynamic temperature of the reagent sheet so that it reaches a temperature range of 37±0.2℃ to meet the test requirements.

[0004] Existing temperature measurement methods include contact and non-contact. The former has relatively high temperature measurement accuracy but requires wiring and has low operational flexibility, while the latter does not require wiring but may have low temperature measurement accuracy.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0027] It should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] Among the current temperature measurement methods, contact temperature measurement uses temperature sensors, longer temperature measurement lines and multi-channel thermometers to measure the temperature of the object being measured. The multi-channel thermometer uploads the temperature data detected by the temperature sensor to the host computer through the data bus. The temperature measurement accuracy of this method can meet the actual needs, but this method has the following problems:

[0029] 1. Connecting the temperature measurement line is cumbersome. The temperature sensor probe needs to be glued to the surface of the incubation plate by means of sticky points. The sticky points are corrosive and can easily cause varying degrees of contamination to the surface. After the temperature measurement is completed, the sticky points are difficult to clean because they are tightly attached to the surface. The sticky points on the sensor surface are also not easy to remove. Usually, a knife or other sharp tools are needed to clean them. In the cleaning process, the sensor itself may be damaged to a certain extent. After repeated use, the possibility of sensor damage or poor accuracy will increase. This situation is usually an invisible manifestation, that is, the operator continues to use the temperature measurement without being sure that the sensor has poor accuracy due to repeated use before, which will inevitably affect the accuracy of the temperature measurement results;

[0030] 2. The lead wires of commonly used temperature sensors are very thin, and they may be easily torn off due to improper operation during the above sticking process, which will cause some rework in the temperature measurement work, undoubtedly increasing the workload;

[0031] 3. In general, the temperature measurement line is long, which will have an adverse effect on the sensor resistance error, thereby reducing the temperature measurement accuracy;

[0032] 4. Commonly used multi-channel thermometers can generally test a limited number of temperature points at the same time due to the limitation of the number of analog acquisition channels. If you want to test more than ten or even more temperature points, you need multiple multi-channel thermometers. There are certain measurement differences between different multi-channel thermometers, which will have an adverse effect on temperature measurement and it is difficult to ensure the consistency of temperature measurement. If you use a multi-channel thermometer to measure temperature, multiple rounds of testing are required, and the total temperature measurement time will be seriously extended.

[0033] Currently, common wireless temperature measurement devices include handheld thermal imagers, temperature guns, etc. The temperature measurement accuracy of ordinary thermal imagers or temperature guns can only reach about ±0.5℃ or even lower. Thermal imagers or temperature guns with higher accuracy may achieve a temperature measurement accuracy of within ±0.2℃. However, during the rotation of the incubation tray, after the incubation tray is pressed by the pressing mechanism, the infrared imaging of the thermal imager or temperature gun can only measure the surface temperature of the pressing mechanism. The position on the surface of the incubation tray corresponding to the placement of the card plate is blocked by the pressing mechanism, and the corresponding position on the surface of the incubation tray cannot be directly measured. In other words, it is obviously not feasible to measure the temperature of the corresponding position on the surface of the incubation tray by an ordinary thermal imager or temperature gun.

[0034] In order to overcome the many difficulties or shortcomings of the above contact or non-contact temperature measurement methods, the present application is based on a dynamic temperature measurement device for a dry biochemical analyzer, which can effectively solve the above problems.

[0035] For details, please refer to Figure 1 As shown, the embodiment of the present application provides a dynamic temperature measurement device for a dry biochemical analyzer, comprising: a plurality of card boards 103 and a main control board 102 wirelessly connected to the plurality of card boards 103, the main control board 102 being connected to a host computer;

[0036] Multiple card plates 103 are respectively arranged in the holes and grooves on multiple reagent sheets at corresponding positions on the surface of the incubation tray 105. A card pressing mechanism is also provided on the incubation tray 105 to simultaneously press the multiple card plates 103 from above so that the card plates 103 and the hole and groove surfaces of the incubation tray are tightly attached. The card plates 103 are used to detect the temperature of the surface of the incubation tray and feed it back to the host computer through the main control board 102.

[0037] The incubation tray surface on the incubation tray 105 is used as the detected object, and the card board 103 performs online real-time temperature detection on the incubation tray surface one by one.

[0038] The card board 103 and the main control board 102 are used in conjunction with each other. The card board 103 detects the temperature of the surface of the incubation plate and feeds the detected temperature back to the main control board 102. The main control board 102 then transmits it to the host computer for processing and display.

[0039] The card board 103 and the main control board 102 are connected wirelessly. Specifically, Figure 2 As shown, a wireless communication module 114 and a first main controller 112 are provided on the main control board 102, a wireless communication chip 203 is provided on the card board 103, and the first main controller 112 is connected to the wireless communication chip 203 and the wireless communication module 114 respectively to realize the wireless connection between the wireless communication chip 203 and the wireless communication module 114.

[0040] The wireless communication chip 203 on the card board 103 transmits the signal to the wireless communication module 114 of the main control board 102 through the first main controller 112 , thereby realizing the function of wirelessly transmitting the signal from the card board 103 to the main control board 102 .

[0041] The wireless communication module 114 on the main control board 102 has the function of wireless communication with multiple wireless communication chips 203, and its basic working principle is to achieve wireless communication connection through the transmission and reception of radio frequency signals. The main controller on the main control board 102 can control the wireless communication module 114 to pair with the wireless communication chips 203 on multiple card boards 103 through USART communication. The wireless communication chip 203 can send the temperature measurement data to the wireless communication module 114 in real time through wireless communication, read the temperature data inside the module regularly through USART communication, and upload it to the host computer for display through the reserved communication interface.

[0042] When the card board 103 and the main control board 102 are used together, the card board 103 is charged through the main control board 102. The main control board 102 is provided with a plurality of charging sockets 108, and the card board 103 is provided with a charging plug 109. The plurality of card boards 103 can be connected to the plurality of charging sockets 108 through any charging plug 109 to charge the plurality of card boards 103.

[0043] The main control board 102 is also provided with a plurality of communication interfaces to support the connection of different external communication devices. For example, the main control board 102 reserves a CAN communication interface 101, an RS485 communication interface 107, and an RS232 communication interface 110 for use by the operator, and has a plurality of charging sockets 108 for charging the card board 103, and a charging plug 109 is provided on the card board 103 to charge the card board 103 after docking with the charging socket 108.

[0044] Figure 1 In the figure, the card plate 103 is placed at a corresponding position on the surface of the incubation tray 105, and the card pressing mechanism 106 presses the card plate 103 to the corresponding position on the surface of the incubation tray 105 to prevent the card plate 103 from shaking or being thrown out when the incubation tray 105 rotates. The rotation of the incubation tray 105 is controlled by the dry biochemical analyzer itself.

[0045] When the dynamic temperature measuring device of the dry biochemical analyzer provided in the embodiment of the present application performs a temperature measuring operation, the card board 103 used for temperature measurement is first inserted into the charging socket 108 on the main control board 102 through the charging plug 109 thereon, and then the main control board 102 is powered, and then the main control board 102 charges the small supercapacitors 205 on each card board 103 through the relevant circuit. After all the card boards 103 are fully charged, the power supply of the main control board 102 is first disconnected, and then the card board 103 is removed from the main control board 102;

[0046] Then, the temperature calibration tooling that has been calibrated by the measurement unit is used to uniformly calibrate the temperature of the card board 103 to ensure the accuracy of its temperature measurement;

[0047] Then remove the card pressing mechanism 106 from the incubation tray 105, and put the card board 103 on the incubation tray 105 in order according to the numbers above, with the device side of the card board 103 facing up and the bottom surface close to the surface of the reagent sheet of the incubation tray 105 to avoid gaps during temperature measurement that may lead to inaccurate measurement;

[0048] The card pressing mechanism 106 is used to press the card plate 103 to prevent the card plate 103 from shaking or being thrown out during the rotation of the incubation tray 105;

[0049] After the host computer is connected to the main control board 102, the wireless communication module 114 (Wi Fi) on the main control board 102 will be paired with all the card boards 103 for wireless connection;

[0050] After all the card boards 103 are successfully connected to the main control board 102, check whether the temperature data uploaded by each card board 103 of the host computer is basically consistent and basically close to the room temperature. If normal, the dynamic temperature measurement operation can be performed;

[0051] Operate the dry biochemical analyzer to rotate the incubation tray 105, and the real-time temperature of the surface of the incubation tray 105 detected by all the card plates 103 in the rotating state can be checked on the host computer;

[0052] After the test has been completed for a certain period of time and the temperature is substantially stable, the temperature detection data uploaded by all the card boards 103 are exported in the host computer, and this round of temperature measurement is completed.

[0053] Therefore, the dynamic temperature measuring device of the dry biochemical analyzer provided in the embodiment of the present application is provided with multiple card plates 103 on the multiple reagent sheets at the corresponding positions on the surface of the incubation disk 105, and the multiple card plates 103 are pressed by the card pressing mechanism on the incubation disk 105. The card plates 103 are used to detect the temperature of the surface of the incubation disk, and are fed back to the host computer through the main control board 102. The dynamic temperature measuring device of the dry biochemical analyzer provided in the embodiment of the present application has the characteristics of small size, light weight, strong operability, good data transmission stability, etc., and can perform dynamic temperature measurement when the incubation disk 105 is rotating. It can be recycled for many times and has good maintainability. At the same time, it also avoids the unfavorable factors such as line resistance error, poor contact, and signal interference of the wired temperature sensor 204, and the temperature measurement error can also reach the required ±0.2°C of the instrument. The dynamic temperature measuring device of the dry biochemical analyzer provided in the embodiment of the present application can not only shorten the temperature measurement time under the condition of the rotating state, but also ensure the accuracy of the test results.

[0054] For further information, please refer to Figure 2 The main control board 102 is provided with a first voltage stabilizer 111 and a first charging circuit 115. The first charging circuit 115 is respectively connected to the plurality of charging sockets 108, and the first voltage stabilizer 111 is used to access a DC adapter.

[0055] For example, the DC adapter 24V power supply transmits electric energy to the charging socket 108 through the first regulator 111 (LDO regulator) and the first charging circuit 115, and the charging plug 109 on the card board 103 is plugged into the charging socket 108 to charge the card board 103. After being fully charged and unplugged, the card board 103 can maintain normal operation for more than 1 hour, which can meet the power demand of a dynamic temperature measurement cycle of the card board 103. Figure 3 In the embodiment, the second charging circuit 212 on the card board 103 has over-current and under-voltage protection functions, which can provide certain protection for the main components. The third regulator 213 (LDO regulator) on the card board 103 can provide stable and reliable voltage for the main components such as its second main controller 202.

[0056] The main control board 102 is provided with a power supply input terminal 104 and a second voltage stabilizer 113 in sequence. The second voltage stabilizer 113 is connected to the first main controller 112 and the wireless communication module 114 respectively.

[0057] The dynamic temperature measuring device of the dry biochemical analyzer is powered by a DC voltage supplied to the main control board 102 by an external adapter through the power input terminal 104. The DC voltage is converted into DC voltages of different levels by different second regulators 113 (LDO regulators) to power the first main controller 112, the wireless communication module 114, the external devices, etc. thereon.

[0058] On this basis, if Figure 6 As shown, the card board 103 includes a wireless communication antenna board 210 and a temperature detection board 208 attached to the bottom of the wireless communication antenna board 210, and the top plane 206 of the wireless communication antenna board 210 is provided with an antenna coil 201, and the two end points of the antenna coil 201 are respectively connected to the two first soldering pads 207 of the wireless communication antenna board 210, and the two first soldering pads 207 are connected to the two second soldering pads 209 on the temperature detection board 208 in a one-to-one correspondence.

[0059] The card board 103 is composed of a wireless communication antenna board 210 and a temperature detection board 208. The total thickness of the wireless communication antenna board 210 is about 2 mm. The middle area of ​​the wireless communication antenna board 210 is hollowed out to form a hollow area 211, the purpose of which is to accommodate the temperature detection board 208 and to make room for the components with a certain height on the temperature detection board 208. The total thickness of the temperature detection board 208 is about 0.8 mm. After the two boards are glued together, the total thickness is controlled to be about 3 mm. Figure 4 shown.

[0060] Figure 4 An antenna coil 201 (indicated by a dotted box) is distributed on the upper surface of the wireless communication antenna board 210. The coil is routed on the top plane 206 around the card board 103 by etching the circuit board. The two ends of the coil are connected to the two first solder pads 207 at the bottom of the wireless communication antenna board 210 through internal routing. At the same time, two second solder pads 209 for the wireless communication circuit are left at corresponding positions on the surface of the temperature detection board 208. The above four solder pads need to be soldered before the two boards are glued together.

[0061] like Figure 5 As shown, the temperature detection board 208 is provided with a temperature sensor 204, a second main controller 202, and a wireless communication chip 203 which are connected in sequence. The second main controller 202 transmits the signal transmitted by the temperature sensor 204 through the temperature detection circuit 214 to the wireless communication chip 203, and sends it to the main control board 102 through the wireless communication chip 203.

[0062] The temperature detection board 208 is affixed with main components such as the main controller 202, the wireless communication chip 203, the embedded ultra-thin temperature sensor 204, and the small super capacitor 205. The highest height of the above components will not be higher than the top plane 206 of the wireless communication antenna board 210, so as to avoid the components being damaged by force when the card pressing mechanism 106 presses (presses onto the top plane 206) the card board 103. The small super capacitor 205 provides the main components on the temperature detection board 208 with the required power supply voltage through the second charging circuit 212 and the third voltage regulator 213.

[0063] The temperature detection board 208 is also provided with a small super capacitor 205, a second charging circuit and a third voltage regulator 213 which are connected in sequence. The third voltage regulator 213 is connected to the second main controller 202 and the wireless communication chip 203, and the small super capacitor 205 is connected to the charging plug 109.

[0064] The main controller 202 has a high-precision AD converter that converts the resistance voltage signal of the embedded temperature sensor 204 into a digital signal, and obtains temperature data through relevant calculations on the signal. The data is transmitted to the wireless communication chip 203 via USART communication and then sent to the main control board 102 via wireless communication.
