Description

Technical Field

[0001] This invention relates to a detection device for measuring clinical physiological indicators, and in particular, a detection device for rapidly measuring biochemical indicators. Background Technology

[0002] Currently, an increasing number of products that can achieve on-site sampling and provide immediate test results are being researched and applied in clinical practice. These types of tests are often referred to as point-of-care testing (POCT).

[0003] For example, there are test strips used to determine hormone levels, such as human chorionic gonadotropin (HCG), luteinizing hormone (LH), and follicle-stimulating hormone (FSH). These test strips typically include a support pad, on which, from upstream to downstream, are stacked a sample pad, a labeling pad, a detection pad, and an absorbent pad. Urine dripped onto the sample pad flows sequentially through these pads, and the hormones in the sample are immobilized in that area by a binding agent on the detection pad. The color depth of the detection pad in the test strip is linearly correlated with the concentration of the sample being tested, thus determining the level of the corresponding hormone in the sample. Besides hormone level determination, there are also test strips for drug testing, allergen analysis, and testing for infectious viruses such as HBV, HCV, HIV, malaria, dengue fever, influenza, Middle East Respiratory Syndrome (MERS), SARS, and 2019-nCoV. With the improvement of people's living standards and increased emphasis on personal health management, the testing of indicators such as blood glucose, uric acid, blood ketones, cholesterol, and lactic acid in the blood is becoming more and more common. This has led to the development of test strips suitable for point-of-care testing using electrochemical and photochemical methods. For point-of-care urinalysis, various combination methods have emerged, such as urine quadruple test strips, urine eleven-piece test strips, and urine fourteen-piece test strips. Test strips can be used directly for testing or can be packaged in a casing.

[0004] After the test strip completes the test, the results can be observed visually or read electronically. For test strips that require visual inspection, the test items can be distinguished by the markings on the test strip or its casing. When using instruments to interpret the results, currently, each test strip is typically paired with a specific instrument. For example, a woman who needs to know her HCG, LH, or FSH hormone levels at home would need not only HCG, LH, and FSH test strips, but also corresponding HCG, LH, and FSH analyzers at home. This not only wastes hardware resources but also makes the testing process cumbersome, as the user needs to ensure that the test strip and the analyzer are compatible. Currently, some manufacturers integrate the detection of HCG, LH, and FSH onto a single test strip and use a single analyzer for result interpretation. However, while this "one-sheet-for-multiple-uses" approach simplifies the testing process, it increases costs for testers who only need to perform one or two tests. Furthermore, the number of tests that can be integrated onto a single test strip is limited, making this approach unsuitable for obtaining a large number of results. Some manufacturers have pre-set test item selection modules on their testing instruments, requiring testers to manually select the corresponding test items for the test strip. While this method achieves "one machine for multiple uses," it increases the complexity of operation by adding the step of manual selection, and also increases the risk of misinterpretation of results due to human error.

[0005] Therefore, an improvement plan is urgently needed to simplify the testing process and make "one machine for multiple uses" more convenient. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a simple and effective detection board with identification information. The type of this detection board is easily identified by the analyzer used to detect it, allowing for detection during the identification process, thus achieving multi-functionality. Furthermore, the identification information on this detection board is easily observed manually and can be used for secondary checks to prevent errors.

[0007] One of the objectives of this invention is to provide a simple and effective detection board with identification information, including an upper plate and a lower plate, which are assembled together to form a housing of the detection board. An identification module for identifying the type of the detection board is provided on the housing. The identification module includes a recessed portion, a non-recessed portion, or a combination of a recessed portion and a non-recessed portion.

[0008] Preferably, it includes at least two identification modules, which are respectively set at different positions on the detection plate.

[0009] Furthermore, the identification module is located at the front end or side of the detection board housing; or the identification module is located at both the front end and side of the housing.

[0010] Furthermore, in the two recognition modules, one recognition module is set as a recessed part and the other recognition module is set as a non-recessed part; or both recognition modules are set as recessed parts; or both recognition modules are set as non-recessed parts.

[0011] Furthermore, one recognition module is located at the upper right corner of the front end of the upper plate and is set as a recessed part, while the other recognition module is located at the upper left corner of the front end of the upper plate and is set as a non-recessed part; or, one recognition module is located at the upper right corner of the front end of the upper plate and is set as a non-recessed part, while the other recognition module is located at the upper left corner of the front end of the upper plate and is set as a recessed part.

[0012] Furthermore, the identification module includes at least one non-recessed portion and one recessed portion, wherein the non-recessed portion contacts the analyzer's detection switch earlier than the recessed portion.

[0013] Furthermore, the identification module is used to trigger the detection switch in the analyzer to identify the detection board type.

[0014] Furthermore, the detection board type is identified by whether the detection switch is triggered by the recessed portion or the non-recessed portion.

[0015] Furthermore, one identification module on the detection board corresponds to a detection switch on the analyzer.

[0016] Furthermore, test strips are provided between the upper and lower plates of the test plate.

[0017] Test strips can employ various detection methods suitable for point-of-care testing, such as photochemical and electrochemical methods, to determine hormone levels, drugs, allergens, physiological indicators in urine, HBV, HCV, HIV, malaria, dengue fever, influenza, Middle East Respiratory Syndrome (MERS), SARS and 2019-nCoV, blood glucose, uric acid, blood ketones, cholesterol, lactic acid, etc.

[0018] The present invention also provides another analyzer for reading the identification information of the detection board described in the present invention, including an upper cover, a lower cover and a detection board insertion port, a circuit board assembled between the upper and lower covers, and a detection switch for determining the type of the detection board mounted on the circuit board; the position of the detection switch in the analyzer corresponds to the position of the identification module of the detection board inserted into the analyzer.

[0019] Furthermore, the non-recessed portion of the detection board's identification module triggers the detection switch in the analyzer to power on the analyzer and identify the detection board type. Even further, the detection board type is identified by whether the detection switch is triggered by a recessed portion or a non-recessed portion.

[0020] Furthermore, when the detection board is inserted into the analyzer, the non-recessed part of the detection board recognition module will touch the button of the detection switch and press the button down to trigger the detection switch; the recessed part of the detection board recognition module will not touch the button of the detection switch.

[0021] Preferably, the circuit board includes two detection switches, each corresponding to one of the two identification modules on the detection board.

[0022] Preferably, the surface of the detection switch facing the detection plate has a sloping structure.

[0023] Furthermore, the detection switch also functions as an analyzer power-on function.

[0024] Furthermore, the circuit board is fixed inside the analyzer via a base. A through hole is provided on the base at the position relative to the detection switch. After the circuit board is assembled onto the base, the button of the detection switch passes through the through hole of the base.

[0025] On the other hand, this invention also provides a method for identifying the type of detection board. The method uses an identification module on the detection board to trigger the analyzer's detection switch, generating a corresponding signal to identify the type of detection board. This achieves multi-functionality with a single device, avoiding human error. Furthermore, it is easy to operate and convenient to use.

[0026] The present invention provides a method for identifying the type of a detection board, comprising a detection board and an analyzer. The detection board comprises a housing formed by assembling an upper plate and a lower plate, and an identification module is provided on the housing. The analyzer comprises an upper cover, a lower cover, and a detection board insertion port, a circuit board assembled between the upper and lower covers, and a detection switch for determining the type of the detection board mounted on the circuit board. The analyzer identifies the type of the detection board by generating a signal corresponding to whether the detection switch of the analyzer is triggered by the identification module.

[0027] Furthermore, the identification module is configured with non-recessed and / or recessed portions. By having the detection switch not triggered by the recessed portion and / or the detection switch triggered by the non-recessed portion, the analyzer generates a signal corresponding to whether the detection switch is triggered or not, thereby identifying the detection board type.

[0028] Furthermore, when the detection switch is not pressed open by the recessed area, the analyzer generates signal 1; when the detection switch is pressed open by the non-recessed area, the analyzer generates a decreasing signal 2; when the detection switch is first pressed open by the non-recessed area, and then the detection switch closes after losing the pressure of the non-recessed area, the analyzer generates a signal 3 that first decreases and then increases.

[0029] Furthermore, the analyzer is powered on or woken from sleep mode by being triggered by the detection switch of the identification module.

[0030] Furthermore, when the detection switch is pressed open by the non-recessed part, it simultaneously powers on the analyzer or wakes it from sleep mode.

[0031] Furthermore, the detection switch includes a first detection switch and a second detection switch.

[0032] Furthermore, the detection board includes two recognition modules; the two recognition modules correspond to the first detection switch and the second detection switch respectively; one recognition module is located at the upper right corner of the front end of the upper board and is set as a recessed part, and the other recognition module is located at the upper left corner of the front end of the upper board and is set as a non-recessed part; or, one recognition module is located at the upper right corner of the front end of the upper board and is set as a non-recessed part, and the other recognition module is located at the upper left corner of the front end of the upper board and is set as a recessed part.

[0033] Furthermore, the detection board is inserted into the analyzer, causing the recessed or non-recessed part of the identification module to advance to the detection switch. Upon detecting that the first and / or second detection switches are pressed, the analyzer's microcontroller detects the type of the detection board. When both the first and second detection switches are pressed, two descending signals 2 are emitted, indicating the detection board is of the first type. Alternatively, when the first detection switch is pressed but the second detection switch is not pressed, a first descending signal 2 is emitted, indicating the detection board is of the second type. Alternatively, when the first detection switch is not pressed but the second detection switch is pressed, a second descending signal 2 is emitted, indicating the detection board is of the third type. Alternatively, when neither the first nor the second detection switch is pressed, signal 1 is emitted, indicating the detection board is of the fourth type.

[0034] Furthermore, if the analyzer's microcontroller is in sleep mode before the detection board is inserted, the signal triggered by the first or second detection switch will wake up the microcontroller first. Then, the microcontroller analyzes the trigger signal of the detection switch to determine the detection type of the detection board. If the microcontroller is already in wake-up mode before the detection board is inserted, the microcontroller will directly analyze the trigger signal of the detection switch to determine the detection type of the detection board.

[0035] Furthermore, another identification module is included, comprising a non-recessed portion and a recessed portion, wherein the non-recessed portion contacts the detector switch of the analyzer earlier than the recessed portion; the analyzer is provided with a detector switch corresponding to the identification module; when the detection board moves forward in the analyzer, when the detector switch is pressed first and then closed, a signal 3 is emitted that first descends and then rises, indicating that the detection board is of another type.

[0036] The beneficial effects of this invention are as follows: By cooperating with the detection switch on the analyzer and the identification module mounted on the detection board, the analyzer can automatically identify the type of detection board being used without requiring the user to select the type, achieving multi-functionality. This reduces user operation steps during the detection process, lowers the rate of human error, and is easy to operate and use. Furthermore, this invention can utilize a single switch system to simultaneously identify different detection board types and enable analyzer wake-up. This significantly reduces hardware resource costs and provides a better user experience. In addition, the identification module mounted on the detection board can not only cooperate with the analyzer to achieve multi-functionality but also allow for manual identification of the corresponding detection board type, providing secondary error prevention and ensuring accurate acquisition of test results.

[0065] The present invention will now be described in detail with reference to the accompanying drawings. These specific embodiments are merely limited examples without departing from the spirit of the present invention, and do not preclude other specific implementation schemes arising from the combination of prior art and the present invention by those skilled in the art.

[0066] like Figures 1 to 6 The test plate 1 shown includes an upper plate 11, a lower plate 12, a test strip 13 mounted between the upper and lower plates, a test result reading window 14, and an identification module 15 indicating the test plate type. The identification module 15 is used to trigger the detection switch in the analyzer 20 to identify the test plate type. Specifically, the identification module 15 determines the test plate type by the presence and location of a recess; that is, by the recess not triggering the detection switch and / or by a non-recessed portion triggering the detection switch. The test strip 13 includes a support pad 131, on which a sample application pad 132, a marking pad 133, a detection pad 134, and an absorbent pad 135 are sequentially arranged from upstream to downstream, stacked together. After the liquid sample is applied to the sample application pad, the sample flows sequentially through the sample application pad, the marking pad, the detection pad, and the absorbent pad. The test strip is mounted between the upper and lower plates, with a portion of the sample application pad located outside the upper and lower plates to receive the liquid sample. The test plate may also include a cover 16 for covering and protecting the exposed sample application pad.

[0067] The identification module includes recessed portions, non-recessed portions, or a combination of recessed and non-recessed portions. The type of the detection board is identified by the number and combination of recessed and non-recessed portions in the identification module, thereby achieving the purpose of identifying the detection type of the detection board. The identification module is provided with at least one recessed portion and / or at least one non-recessed portion.

[0068] There are various ways to set the recessed and non-recessed parts in the recognition module, including but not limited to: First, the recognition module consists entirely of non-recessed parts, that is, the recognition module consists entirely of one or more non-recessed parts; Second, the recognition module consists entirely of recessed parts, that is, the recognition module consists entirely of one or more recessed parts; Third, the recognition module includes both recessed and non-recessed parts, and the recessed area and non-recessed area are one or more, etc.

[0069] The identification module can be one, or at least two, such as two, three, four, etc. The identification module is located on the detection plate, specifically on the outer shell of the detection plate, that is, on the shell formed by the upper and lower plates. The identification module is disposed at the front end or side of the detection plate shell, or simultaneously at the front end and side. The front end described here includes the upper and lower surfaces of the front end of the shell, as well as the portion protruding from the front end of the shell. (In...) Figures 1 to 6 In the example shown, the front end or side of the detection plate refers to the front end or side of the detection plate that contacts the analyzer.

[0070] There are various ways to combine the identification modules, including but not limited to: 1. Two identification modules, which are respectively set at different positions on the detection plate; for example, the two identification modules are set at the front end or two side walls of the upper plate; one identification module is set with a recessed part, and the other identification module is set with a non-recessed part; or both identification modules are set with recessed parts; or both identification modules are set with non-recessed parts. 2. Two identification modules, one identification module is located at the upper right corner of the front end of the upper plate and is set with a recessed part, and the other identification module is located at the upper left corner of the front end of the upper plate and is set with a non-recessed part; or, one identification module is located at the upper right corner of the front end of the upper plate and is set with a non-recessed part, and the other identification module is located at the upper left corner of the front end of the upper plate and is set with a recessed part. 3. One or more identification modules, wherein each identification module includes at least one non-recessed part and one recessed part, wherein the non-recessed part is closer to the front end of the detection plate than the recessed part, and the non-recessed part contacts the detector switch of the analyzer earlier than the other recessed part. 4. Four identification modules, respectively set at the front end and both sides of the detection plate.

[0071] In a design scheme, such as Figure 27 and Figure 28 As shown, the detection board includes an identification module 15 located at the front end of the upper plate 11. The identification module has the following two configuration modes: the first mode is that there is no recess at the front end of the upper plate, that is, all identification modules are non-recessed parts 151. Figure 28 As shown; the second mode is that the entire front end of the upper plate is set as a recessed part 152, as shown. Figure 27 As shown.

[0072] In another design scheme, such as Figures 4 to 6The detection board shown includes two recognition modules 15 located at the front end of the upper plate 11. The two recognition modules have the following three configuration modes: The first mode is that there is no recess at the front end of the upper plate, that is, both recognition modules are non-recessed. Figure 4 As shown; the second mode has a recessed area in the upper right corner of the upper plate (first recognition module), but no recessed area in the upper left corner (second recognition module). Figure 5 As shown; the third mode has no recess in the upper right corner of the upper plate (first recognition module), but has a recess in the upper left corner (second recognition module). Figure 6 As shown; among them, the second and third modes are settings that change the positional relationship between the recessed part and the non-recessed part when the recognition module is set with a recessed part and a non-recessed part.

[0073] The analyzer 20 used in conjunction with the detection plate, such as Figures 7 to 10 As shown, the analyzer includes an upper cover 21, a lower cover 22, and a circuit board 23 mounted between the upper and lower covers. The circuit board 23 is fixed inside the analyzer via a base 24. The upper and lower covers are assembled together to form the outer shell of the analyzer, forming a detection board insertion port 28 at the front end. The base 24 has a slot 25 for inserting the detection board on the opposite side of the circuit board mounting. A detection switch 26 for identifying the type of detection board is mounted on the circuit board. A through hole 241 is provided on the base 24 at a position relative to the detection switch. After the circuit board is mounted on the base, the button 27 of the detection switch 26 mounted on the circuit board extends through the through hole 241 into the slot 25. When the detection board is inserted into the slot of the analyzer, the detection board identification module 15 is located above the button 27 of the detection switch 26. If the identification module 15 is set as a non-recessed part relative to the detection switch 26, the outer shell of the non-recessed detection plate will touch the button 27 of the detection switch and press the button down to trigger the detection switch 26 to open; if the identification module is set as a recessed part relative to the detection switch, the outer shell of the recessed detection plate will not touch the button of the detection switch, and the button will not trigger the switch to open due to being pressed down by the detection plate.

[0074] The shape of button 27 can be sloping, hemispherical, cuboid, or cube. For example, the side of the button facing the detection plate can be a sloping structure, which makes it easier for the detection plate to push and press down the button after it is pushed into the slot and comes into contact with it.

[0075] The analyzer 20 can be equipped with a separate power-on switch. In one design, the detection board type detection switch 26 can also function as the analyzer's power-on function. The non-recessed portion of the detection board identification module 15 triggers the detection switch 26 in the analyzer to power on and identify the detection board type. That is, when the detection switch 26 is triggered, the analyzer 20 is powered on and started, and the started analyzer 20 can determine the type of detection board based on the triggering of the detection switch.

[0076] The analyzer 20 may also include a detection plate ejection assembly, which includes an ejection connector 291 and an ejection button 292 installed in the analyzer housing.

[0077] In some designs, one identification module on the detection board corresponds to one detection switch on the analyzer. For example, the detection board may have two identification modules, and correspondingly, the analyzer may have two detection switches, with their positions corresponding one-to-one.

[0078] The following example, using the identification module 15 with different modes set on the detection board to distinguish between the hCG detection board, the FSH detection board, and the LH detection board, will be used to further illustrate the point.

[0079] like Figure 4 The detection plate shown contains test strips for analyzing hCG levels in urine. The identification module 15 of this detection plate does not have a recessed portion relative to the button 27 of the analyzer's detection switch 26; that is, the identification module at the front of the upper plate is entirely non-recessed 151. Figure 4 In one example, the non-recessed portion is the portion of the upper surface of the upper plate 11 that extends horizontally to the front end of the upper plate.

[0080] like Figure 5 The detection plate shown contains test strips for analyzing LH levels in urine. The identification module 15 of the detection plate has a right recess 152 (first identification module) at the position of button 271 of the first detection switch 261 of the analyzer; that is, a recessed structure is provided at the upper right corner of the front end of the upper plate. The identification module 15 of the detection plate does not have a recess at the position of button 272 of the second detection switch 262 of the analyzer; that is, a non-recessed portion 151 (second identification module) is provided at the upper left corner of the front end of the upper plate.

[0081] like Figure 6 The detection plate shown contains test strips for analyzing FSH levels in urine. The identification module 15 of the detection plate has a left recess 153 relative to the button position of the second detection switch of the analyzer; that is, a left recessed structure is provided at the upper left corner of the front end of the upper plate. The identification module 15 of the detection plate does not have a recess relative to the button position of the first detection switch of the analyzer; that is, a non-recessed part 151 is provided at the upper right corner of the front end of the upper plate.

[0082] The depth of the recess should be set such that the bottom of the recess does not touch the detection switch button.

[0083] The type of the detection board can be determined by whether the detection switch on the analyzer is pressed by the detection board's identification module. The analyzer and the detection board type detection switch will be described in detail below. Alternatively, the tester can determine the type of detection board by directly observing the detection board's identification module, without using the analyzer. For detection boards where the tester directly determines the detection type, the position of the recessed or non-recessed portion on the identification module may not correspond to the position of the analyzer's detection switch.

[0084] For example, if the instrument detects or the human eye observes that all the identification modules of the detection plate are non-recessed, then the detection plate is determined to be an HCG detection plate; or if the detection plate identification module has only one right recess, then the detection plate is determined to be an LH detection plate; or if the detection plate identification module has only one left recess, then the detection plate is determined to be an FSH detection plate; or if the detection plate identification module has both a right and a left recess, then the detection plate is determined to be an E2 (estradiol) detection plate.

[0085] Those skilled in the art can, based on the number of relevant testing items, set different numbers of identification modules on the testing plate, different numbers of recesses on the identification modules, and determine the positions of the identification modules and recesses on the testing plate; correspondingly, a different number of detection switches are set at corresponding positions on the analyzer to correspond to the identification modules. The correspondence between identification modules and testing categories can also be established through the number of recesses, the positions of recesses, or combinations of the number and positions of recesses. The recesses can be designed as other structures with similar functions, such as notches.

[0086] The following is based on Figure 5 Taking the LH detection board shown as an example, this further illustrates how the detection board identification module works in conjunction with the analyzer's detection switch to determine the type of detection board.

[0087] like Figures 11 to 17 The analyzer circuit board shown has two detection switches arranged side-by-side: a first detection switch 261 and a second detection switch 262. The diagram is provided to more clearly illustrate the interaction between the detection board's identification module and the analyzer's detection switches. Figure 11 and Figure 12The example diagrams omit the mounting components for installing the circuit board onto the analyzer housing; for example, the base is not shown in these diagrams. When the right-side-missing detection board is inserted into the analyzer, the identification module relative to the analyzer has a right-side recess 152 (first identification module). The bottom wall of the recess does not contact the first button 271. Therefore, the first button 271 will not be pressed down during the insertion of the detection board, and thus the first detection switch 261 cannot be triggered by the first button. Consequently, the signal from the first detection switch 261 to the microcontroller remains a high-level signal (signal 1). The second button 272 of the second detection switch 262 relative to the analyzer is a non-recessed portion 151 (second identification module). The wall of the non-recessed portion contacts the second button 272. During the insertion of the detection board into the analyzer, the second button 272 is pressed down by the non-recessed portion, triggering the second detection switch 262 and changing the connected microcontroller pin from high to low, thus generating a falling-edge signal (signal 2). Once the analyzer receives the signals from the first detection switch 261 (unchanged) and the falling edge of the second detection switch 262, it can determine that the inserted detection board is an LH detection board.

[0088] The detection board type identification module 15 can also be set on the side of the detection board, and the type of the detection board can be determined by whether there is a recess in the side wall and the location of the recess. For example, Figures 18 to 21 As shown. The configuration of the recessed portion includes, but is not limited to, no recessed portion on either side wall of the detection plate; or a recessed portion on one side wall of the detection plate and no recessed portion on the other side wall; or recessed portions on both side walls, etc. Figure 18 and Figure 19 The identification module of the detection board shown does not have a recessed portion, and the button of the detection switch is correspondingly installed on the inner side of the detection switch. During the process of inserting the detection board 1 into the analyzer, the first detection switch 261 and the second detection switch 262 are triggered by the identification module of the detection board pressing the switch button. Figure 20 and Figure 21 The detection board identification module shown has a recessed portion 154 on one side and a recessed portion on the other side. During the insertion of the detection board 1 into the analyzer, the first detection switch 261 is pressed by the identification module of the detection board and triggered, while the second detection switch 262 is not pressed by the identification module of the detection board and is therefore not triggered.

[0089] Figure 22 and Figure 23This invention describes the working principle of an analyzer for identifying the type of detection board. The circuit consists of two circuits: the first circuit includes resistor R1, capacitor C1, detection switch S1, VCC power supply terminal, signal ground, and the P0.0 terminal of the microcontroller; the second circuit includes resistor R2, capacitor C2, detection switch S2, VCC power supply terminal, signal ground, and the P0.1 terminal of the microcontroller. When detection switch S1 or S2 is not pressed, the voltages of P0.0 and P0.1 of the microcontroller are consistent with the VCC voltage, and the detection switch provides a constant high-level signal (signal 1) to the microcontroller. When detection switch S1 or S2 is pressed, the microcontroller's P0.0 and P0.1 terminals are connected to signal ground, and the voltages of P0.0 and P0.1 are pulled low by signal ground, changing from high to low, thus generating a falling edge signal (signal 2) to the microcontroller.

[0090] The analyzer can be powered by button batteries, alkaline batteries, rechargeable lithium batteries, solar cells, switching power supplies, etc.

[0091] An analytical method for analyzing analytes in samples using the detection plate and analyzer described in this invention includes the following steps: inserting the detection plate into the analyzer; triggering at least one detection switch, which generates an external trigger signal to the microcontroller. Upon receiving this trigger signal, the microcontroller generates an external interrupt to wake up. The microcontroller, awakened from sleep mode, prioritizes processing the interrupt program triggered by the detection switch, determining the test strip type within the interrupt program. If the detection plate pops out of the analyzer after the microcontroller wakes up, or if the detection plate is incorrectly positioned or loose, causing the button not to be pressed, the detection switch generates a rising edge signal to the microcontroller, triggering the microcontroller's detection plate position monitoring program and informing the microcontroller of the abnormal detection plate position. In the detection plate position monitoring program, the microcontroller monitors the switch's pressing state to determine whether the test strip is properly installed or whether a different type of test strip has been used. Adding the sample to the test strip; the analyzer retrieves the corresponding algorithm based on the detection plate type to interpret the test results of the test strip; the analyzer outputs the test results.

[0092] by Figures 4 to 6 Taking the detection board and analyzer as an example, and combining them... Figure 22 and Figure 23 Please provide a detailed explanation of the sample analysis methods.

[0093] Step 1: Take out the analyzer and the test plate, and insert the test plate into the slot from the analyzer's insertion port.

[0094] Step 2: As the detection board is inserted, the non-recessed part of the detection board identification module will press the button of detection switch S1 and / or S2. The detection switch that is pressed is triggered by the button, and the trigger information of the trigger switches S1 and S2 is transmitted to the microcontroller.

[0095] When insert Figure 4 The detection board shown has its first detection switch S1 and second detection switch S2 on the circuit board pressed together. The microcontroller receives the signal combination that both S1 and S2 are triggered. After signal analysis, the microcontroller will determine that the detection board currently inserted into the analyzer is used to detect HCG.

[0096] When insert Figure 5 The detection board shown has its first detection switch S1 (261) button 271 not pressed by the detection board, and the second detection switch S2 (262) button 272 pressed by the detection board. The microcontroller receives the signal combination that S1 is not triggered and S2 is triggered. After signal analysis, the microcontroller will determine that the detection board currently inserted into the analyzer is used to detect LH.

[0097] When insert Figure 6 The detection board shown has its first detection switch S1 button pressed, while the detection switch S2 button is not pressed. The microcontroller receives the signal combination of S1 being triggered and S2 not being triggered. After signal analysis, the microcontroller will determine that the detection board currently inserted in the analyzer is used to detect FSH.

[0098] Step 3: The analyzer starts the test program corresponding to the type of test board.

[0099] Step 4: The test ends and the test results are displayed.

[0100] If the microcontroller is in sleep mode before the detection board is inserted, the signal triggered by the detection switch will wake up the microcontroller first. Then the microcontroller analyzes the trigger signal of the detection switch to determine the detection type of the detection board.

[0101] If the microcontroller is already in a wake-up state before the detection board is inserted, the microcontroller will directly analyze the trigger signal of the detection switch to determine the detection type of the detection board.

[0102] An optional, non-essential step is for the analyzer to display the detection type of the detection plate on the analyzer's display screen 30.

[0103] Different designs of the detection plate and analyzer result in different analytical systems. In some systems, the sample is already added to the detection plate before it is inserted into the analyzer, while in others, the sample is added to the detection plate after it has been inserted into the analyzer and the type of detection plate has been confirmed.

[0104] when Figures 4 to 6 The detection plate inserted into the analyzer will produce Figure 26The diagram shows two signals, signal 1 and signal 2. When the recessed part of the detection board's identification module engages with the analyzer's detection switch, the analyzer generates signal 1 and transmits it to the microcontroller. Signal 1 does not generate a rising or falling signal; that is, signal 1 is a constant high-level signal. When the non-recessed part of the detection board's identification module engages with the analyzer's detection switch, the analyzer generates signal 2 and transmits it to the microcontroller. When the switch button is pressed by the non-recessed area of ​​the identification module, a falling signal 2 is generated.

[0105] When the detection switch also functions as the analyzer's power-on function, the identification module on the detection board needs to include a non-recessed portion to generate signal 2. The microcontroller is then activated by the decrease in the signal level of signal 2. If all identification modules on the detection board are recessed portions, the analyzer's switch cannot be pressed. Therefore, the analyzer cannot rely solely on the identification module to determine whether the test strip has been inserted and to activate the analyzer; an additional power-on switch is required.

[0106] To better realize the function of the detection switch as both a power switch and a power-on switch, in such cases... Figure 24 In the optimized design of the detection board, a non-recessed portion 151 and a recessed portion 154 are sequentially arranged on a recognition module. The non-recessed portion contacts the detection switch earlier than the recessed portion 154. When Figure 24 During the insertion of the detection board into the analyzer, the front end of the detection board identification module 15 will first press the button on the detection switch 26. Then, as the detection board continues to be inserted until it is fully inserted, the detection switch will be positioned... Figure 24 The detection switch 26, previously pressed by the non-recessed portion 151, will pop out again in the recessed portion 154 of the detection board. Throughout the insertion process, the analyzer generates a pulse signal that transitions from high to low and then back to high, and transmits it to the microcontroller, such as... Figure 26 Signal 3 is shown. The analyzer detects the falling signal of signal 3, determines that the detection board has been inserted, and wakes up the analyzer. Immediately afterwards, the analyzer detects the rising signal of signal 3, and determines that the detection board is fully inserted. Simultaneously, the analyzer determines the type of detection board that matches the signal based on the sequence of falling and rising signals in signal 3. For example, we can set... Figure 24 The test panel shown is used for drug detection.

[0107] by Figure 25 The detection board shown includes two recognition modules. The first recognition module includes a recessed portion 152 located in the upper right corner, and the second recognition module has a non-recessed portion 151 and a recessed portion 154 sequentially arranged in the upper left corner. The non-recessed portion 151 contacts the detection switch earlier than the recessed portion 154. Figure 25During the insertion of the detection board into the analyzer, the first identification module, i.e., the upper right corner, only includes a recessed portion; therefore, the detection switch will not be pressed, and the analyzer detects that the detection switch in the first identification area generates signal 1. Simultaneously, the analyzer detects that the detection switches corresponding to the non-recessed portion 151 and another recessed portion 154 in the upper right corner of the second identification module generate signal 3. When the analyzer's microcontroller detects these two sets of differing signals, it determines the type of detection board that matches them. For example, we can set... Figure 25 The test plate shown is used to analyze estradiol.
