Description

TECHNICAL FIELD

[0001] The present application relates to a detection device and method for determining a clinical physiological index, in particular a method for identifying the type of detection plate in a detection device for rapid determination of a biochemical index. BACKGROUND

[0002] At present, more and more products that can realize on-site sampling and obtain detection results immediately are researched and applied in clinical, and such detection is commonly referred to as point-of-care testing (POCT).

[0003] For example, a test paper for judging hormone levels, such as human chorionic gonadotropin (HCG), luteinizing hormone (LH), and follicle-stimulating hormone (FSH). Such test papers generally include a support pad, on which a sample pad, a marker pad, a detection pad, and a water absorption pad are sequentially arranged from upstream to downstream, and they are stacked together. The urine dropped on the sample pad flows through the sample pad, the marker pad, the detection pad, and the water absorption pad in turn, and the hormone in the sample is fixed in the area by the binder on the detection pad. The color depth of the detection pad in the test paper is linearly related to the concentration of the sample to be detected, so as to judge the level of the corresponding hormone in the sample. In addition to the determination of hormone levels, there are also drug detection, allergen analysis, HBV, HCV, HIV, malaria, dengue fever, influenza, Middle East respiratory syndrome, SARS, and 2019-nCoV infectious virus test papers. With the improvement of people's living standards and the emphasis on self-health management, the detection of blood glucose, uric acid, blood ketone, cholesterol, lactic acid, and other indicators in blood is also increasing, and corresponding test papers suitable for instant detection by electrochemical method, photochemical method, etc. are produced. For the instant detection of urine routine, various combination methods appear, such as urine four-in-one test paper, urine eleven-in-one test paper, urine fourteen-in-one test paper, etc. The test paper can be directly used for detection, or the test paper can be assembled in a shell.

[0004] When the test paper completes the detection, the detection result can be known by naked eye observation or read by electronic equipment. For the test paper observed by naked eye, people can distinguish the detection items through the markers arranged on the test paper or the test paper shell. The current common method for reading the result by using an instrument is that one item of test paper corresponds to one specific instrument. For example, a woman needs to know her HCG, LH or FSH hormone level at home, and she not only needs to prepare HCG, LH and FSH test papers, but also needs to correspondingly prepare HCG detector, LH detector and FSH detector at home. This not only causes the waste of detection hardware resources, but also makes the detection process cumbersome, because the tester needs to ensure that the test paper being used and the detector being prepared for measurement correspond to each other. At present, some manufacturers integrate the detection of HCG, LG and FSH on one test paper, and use one detector to complete the result reading. However, this "one paper for multiple uses" method can simplify the operation process of the tester, but when the tester only needs to detect one or two detection items, it will increase the cost of the tester; and the number of detection items that can be integrated on the test paper is limited, so "one paper for multiple uses" is not suitable for obtaining a large number of detection results. Some manufacturers preset a detection item selection module on the detector, and the tester needs to manually select the test item corresponding to the test paper; although this method realizes "one machine for multiple uses", but because the step of manually selecting the detection item by the tester is added, the operation is more complicated, and the manual misoperation brings the misjudgment of the detection result.

[0005] Therefore, it is very necessary to improve the scheme to simplify the detection operation process and make "one machine for multiple uses" more convenient. SUMMARY

[0006] In order to improve the deficiencies in the prior art, the present application provides a simple and effective method for identifying the type of detection board, which triggers the detection switch of the analyzer through the identification module on the detection board to generate a corresponding signal to identify the type of detection board, thereby realizing the function of "one machine for multiple uses" and avoiding human misoperation.

[0066] The present invention will be described in detail below 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 exclude other specific implementation plans that can be produced by combining the prior art with the present invention by those skilled in the art.

[0067] 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 that indicates the test plate type. Identification module 15 is used to trigger a detection switch in an analyzer 20 to identify the test plate type. Specifically, identification module 15 determines the test plate type based on the presence and location of a recessed portion; that is, the plate type is determined by whether the recessed portion does not trigger the detection switch and / or the non-recessed portion triggers the detection switch. The test strip 13 includes a support pad 131, on which are stacked a sample loading pad 132, a marking pad 133, a detection pad 134, and an absorbent pad 135, arranged in order from upstream to downstream. After a liquid sample is applied to the sample loading pad, the sample flows through the sample loading pad, marking pad, detection pad, and absorbent pad in sequence. The test strip is mounted between the upper and lower plates, with a portion of the sample loading pad located outside the upper and lower plates to receive the liquid sample. The test plate may also include a cover 16 to cover and protect the exposed sample loading pad.

[0068] The identification module includes a recessed portion, a non-recessed portion, or a combination of these. The number and combination of recessed and non-recessed portions in the identification module are used to identify the type of test board, thereby achieving the purpose of identifying the test type of the test board. The identification module is provided with at least one recessed portion and / or at least one non-recessed portion.

[0069] The recessed and non-recessed parts of the identification module can be arranged in various ways, including but not limited to: 1. Both identification modules are non-recessed parts, i.e. both identification modules are one or more non-recessed parts; 2. Both identification modules are recessed parts, i.e. both identification modules are one or more recessed parts; 3. Both identification modules include recessed and non-recessed parts, and the recessed and non-recessed parts are one or more, etc.

[0070] 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, especially on the shell of the detection plate, i.e. on the shell formed by the upper plate and the lower plate cover. The identification module is arranged at the front end or side of the detection plate shell, and can also be arranged at the front end and side at the same time. The front end described here includes the upper surface and lower surface of the front end of the shell, and also includes the part protruding from the front end of the shell. In the example shown in Figures 1 to 6 The front end or side of the detection plate refers to the front end or side of the end of the detection plate in contact with the analyzer.

[0071] The identification module can be arranged in various ways, including but not limited to: 1. Including two identification modules, the identification modules are arranged at different positions of the detection plate; for example, two identification modules are arranged at the front end or two side walls of the upper plate; one of the identification modules is arranged as a recessed part, and the other identification module is arranged as a non-recessed part; or both identification modules are arranged as recessed parts; or both identification modules are arranged as non-recessed parts. 2. Including two identification modules, one identification module is located at the upper right corner of the front end of the upper plate and is arranged as 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 arranged as 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 arranged as 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 arranged as a recessed part. 3. Including one or more identification modules, wherein one identification module includes at least one non-recessed part and a recessed part, and 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 detection switch of the analyzer earlier than the other recessed part. 4. Including four identification modules, arranged at the front end and both sides of the detection plate.

[0072] In one design scheme, as shown in Figure 27 and Figure 28 The detection plate includes an identification module 15 located at the front end of the upper plate 11, and the identification module has the following two arrangement modes: the first mode is that the front end of the upper plate is not arranged as a recessed part, i.e. both identification modules are non-recessed parts 151, Figure 28 as shown; the second mode is that the front end of the upper plate is arranged as a recessed part 152, as shown in Figure 27 .

[0073] In another design scheme, as shown inFigures 4 to 6 The detection board shown includes two identification modules 15 located at the front end of the upper plate 11. The two identification modules have the following three setting modes: the first mode is that there is no recessed portion at the front end of the upper plate, that is, both identification modules are non-recessed portions. Figure 4 As shown; the second mode is that there is a recessed portion in the upper right corner of the upper plate (the first identification module), and there is no recessed portion in the upper left corner (the second identification module), Figure 5 As shown; the third mode is that there is no recessed portion in the upper right corner of the upper plate (first identification module), and there is a recessed portion in the upper left corner (second identification module) Figure 6 As shown; wherein, the second mode and the third mode are settings in which the positional relationship between the recessed portion and the non-recessed portion is changed when the identification module is provided with a recessed portion and a non-recessed portion.

[0074] The analyzer 20 used in conjunction with the detection plate, such as Figures 7 to 10 As shown, it includes an upper cover 21, a lower cover 22, and a circuit board 23 assembled between the upper and lower covers. The circuit board 23 is fixed in the analyzer via a base 24. The upper cover and the lower cover are assembled together to form the shell of the analyzer, and a detection board insertion port 28 is formed at the front end. The other side of the base 24 relative to the circuit board is provided with a slot 25 for inserting the detection board. A detection switch 26 for distinguishing the type of detection board is installed on the circuit board, and a through hole 241 is provided on the base 24 at a position relative to the detection switch. After the circuit board is assembled to the base, the button 27 of the detection switch 26 installed on the circuit board passes through the through hole 241 and extends into the slot 25. When the detection board is inserted into the slot of the analyzer, the identification module 15 of the detection board 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 non-recessed detection board shell will touch the detection switch button 27 and press the button down to trigger the detection switch 26 to turn on; if the identification module is set as a recessed part relative to the detection switch, the recessed detection board shell will not touch the detection switch button, and the button will not trigger the switch to turn on because it is pressed down by the detection board.

[0075] The shape of the button 27 can be set to be sloped, hemispherical, rectangular or cube, etc. For example, the side of the button facing the detection board is a slope structure, which is more conducive to the detection board pushing and pressing the button after it is pushed into the slot and contacts the button.

[0076] The analyzer 20 can be provided with a separate power switch. In one design, the test board type detection switch 26 can also serve as the analyzer power-on function. The non-recessed portion of the test board identification module 15 triggers the detection switch 26 in the analyzer, causing the analyzer to power on and identify the test board type. Specifically, when the detection switch 26 is triggered, the analyzer 20 powers on and starts up. Simultaneously, the activated analyzer 20 can determine the type of test board based on the triggering of the detection switch.

[0077] The analyzer 20 can also include a detection plate ejection assembly, which includes an ejecting connecting block 291 and an ejecting button 292 mounted in the analyzer housing.

[0078] In some designs, one identification module on the detection plate corresponds to one detection switch on the analyzer. For example, two identification modules are provided on the detection plate, and two detection switches are provided on the analyzer, with a one-to-one correspondence between the positions of the two.

[0079] The following will be further described with an example of distinguishing hCG detection plates, FSH detection plates and LH detection plates by using identification modules 15 of different modes provided on the detection plates.

[0080] As shown in FIG. 1, the detection plate stores test papers for analyzing the content of hCG in urine. Figure 4 In the example shown in FIG. 1, the non-recessed part is a part of the upper surface of the upper plate 11 extending horizontally to the front end of the upper plate. Figure 4

[0081] As shown in FIG. 2, the detection plate stores test papers for analyzing the content of LH in urine. Figure 5 In the example shown in FIG. 2, the right recessed part 152 (first identification module) is provided at the upper right corner of the front end of the upper plate, and the non-recessed part 151 (second identification module) is provided at the upper left corner of the front end of the upper plate.

[0082] As shown in FIG. 3, the detection plate stores test papers for analyzing the content of FSH in urine. Figure 6 In the example shown in FIG. 3, the left recessed part 153 is provided at the upper left corner of the front end of the upper plate, and the non-recessed part 151 is provided at the upper right corner of the front end of the upper plate.

[0083] The depth of the recessed part is set to at least ensure that the bottom of the recessed part does not touch the detection switch button.

[0084] ​The type of the detection plate can be determined by whether the detection switch of the analyzer is pressed by the identification module of the detection plate. The analyzer and the detection plate type detection switch will be described in detail below. The tester can also determine the type of the detection plate currently used by directly observing the detection plate identification module without the analyzer. The position of the recess or non-recess on the detection plate identification module of the detection plate determined by the tester directly observing the detection plate can not correspond to the analyzer detection switch.

[0085] For example, when the instrument detects or the human eye observes that all the identification modules of the detection plate are non-recesses, it is determined that the detection plate is an HCG detection plate; or when it is detected or observed that the identification module of the detection plate is provided with only one right recess, it is determined that the detection plate is an LH detection plate; or when it is detected or observed that the identification module of the detection plate is provided with only one left recess, it is determined that the detection plate is an FSH detection plate; or when it is detected or observed that the identification module of the detection plate is provided with both a right recess and a left recess, it is determined that the detection plate is an E2 (estradiol) detection plate.

[0086] The skilled in the art can set different numbers of identification modules on the detection plate according to the number of relevant detection items, set different numbers of recesses on the identification modules, and set the positions of the identification modules and the recesses on the detection plate; and correspondingly, set different numbers of detection switches on the analyzer at the corresponding positions to correspond to the identification modules. The corresponding relationship between the identification modules and the detection categories can also be completed by the number of recesses, or the position of the recesses, or the arrangement and combination of the number of recesses and the position of the recesses. The recesses can be designed as other structures with similar functions, such as notches.

[0087] The following will take the LH detection plate shown in Figure 5 as an example to further illustrate the cooperation of the detection plate identification module and the analyzer detection switch to determine the type of the detection plate.

[0088] As shown in the analyzer circuit board shown in Figures 11 to 17 , two detection switches are arranged side by side, which are a first detection switch 261 and a second detection switch 262. In order to more clearly express the cooperation between the detection plate identification module and the analyzer detection switch, Figure 11 and Figure 12The mounting member for mounting the circuit board to the analyzer housing is omitted in the example figures, for example, the base is not drawn in these figures. When the detection board with the right recess is inserted into the analyzer, the identification module is at the right recess 152 (first identification module) relative to the analyzer, the bottom wall of the recess does not contact the first button 271, so the first button 271 cannot be pressed downward during the process of inserting the detection board into the analyzer, and thus the first detection switch 261 cannot be triggered by the first button to be turned on, so the signal of the first detection switch 261 to the single-chip microcomputer is always a high-level signal (signal 1). The second detection switch 262 of the identification module is at the non-recess 151 (second identification module) relative to the second button 272 of the analyzer, the wall of the non-recess contacts the second button 272, so the second button 272 can be pressed downward during the process of inserting the detection board into the analyzer, and thus the second detection switch 262 can be triggered by the second button 272 to change the pin of the single-chip microcomputer connected thereto from high level to low level, thereby generating a falling edge signal (signal 2). After the analyzer obtains the unchanged first detection switch 261 and the falling edge signal of the second detection switch 262, it can be determined that the inserted detection board is an LH detection board.

[0089] The detection board type identification module 15 can also be arranged at the side of the detection board, and the type of the detection board is determined by whether the side wall has a recess and the position of the recess, for example Figures 18 to 21 The setting modes of the recess include but are not limited to that the two side walls of the detection board are not provided with a recess, or one side wall of the detection board is provided with a recess and the other side wall is not provided with a recess, or both side walls are provided with a recess, etc. Figure 18 and Figure 19 The identification module of the detection board shown in FIG. 13 is not provided with a recess, and the buttons of the detection switches are correspondingly arranged on the inner side of the detection switches. During the process of inserting the detection board 1 into the analyzer, the first detection switch 261 and the second detection switch 262 are pressed to the switch buttons by the identification module of the detection board and are triggered. Figure 20 and Figure 21 The detection board identification module shown in FIG. 14 is provided with a recess 154 on one side, and is provided with a recess on the other side. During the process of inserting the detection board 1 into the analyzer, the first detection switch 261 is pressed to the switch button by the identification module of the detection board and is triggered, and the second detection switch 262 is not pressed by the identification module of the detection board and is not triggered.

[0090] Figure 22 and Figure 23The working principle of the analyzer of the present application for recognizing the type of detection plate. The circuit is composed of two circuits: the first circuit includes resistor R1, capacitor C1, detection switch S1, VCC power supply terminal, signal ground and P0.0 terminal of the single-chip microcomputer; the second circuit includes resistor R2, capacitor C2, detection switch S2, VCC power supply terminal, signal ground and P0.1 terminal of the single-chip microcomputer. When the detection switch S1 or S2 is not pressed by the key, the voltage of P0.0 and P0.1 of the single-chip microcomputer is consistent with the VCC voltage, and the detection switch provides a high-level signal (signal 1) to the single-chip microcomputer. When the detection switch S1 or S2 is pressed by the key, the P0.0 and P0.1 of the single-chip microcomputer connected to the detection switch are connected to the signal ground, and the voltage of P0.0 and P0.1 is pulled down by the signal ground, thereby changing from high level to low level, and generating a falling edge signal (signal 2) to the single-chip microcomputer.

[0091] The power supply of the analyzer can be selected from a button cell, an alkaline battery, a rechargeable lithium battery, a solar cell, a switching power supply and the like.

[0092] The analysis method for analyzing the analyte in the sample by using the detection plate and the analyzer of the present application comprises the following steps: inserting the detection plate into the analyzer; at least one detection switch is triggered, and the triggered detection switch generates an external trigger signal to the single-chip microcomputer. After receiving the trigger signal, the single-chip microcomputer generates an external interrupt to wake up the single-chip microcomputer. The single-chip microcomputer woken up from hibernation will preferentially process the interrupt program triggered by the detection switch, and determine the type of test paper in the interrupt program. If the detection plate is ejected from the analyzer after the single-chip microcomputer is woken up or the detection plate is not installed correctly, loose or the like, the button is not pressed. Then the detection switch generates a rising edge signal to the single-chip microcomputer, thereby triggering the detection plate position monitoring program of the single-chip microcomputer to inform the single-chip microcomputer that the position of the detection plate is abnormal. In the detection plate position monitoring program, the single-chip microcomputer monitors the pressing state of the switch, thereby determining whether the test paper strip is installed in place or whether other types of test paper strips are replaced. Adding the sample to the test paper; the analyzer retrieves the corresponding algorithm according to the type of the detection plate to judge the test result of the test paper; and the analyzer gives the detection result.

[0093] The detection plate and the analyzer cooperate as an example, and the sample analysis method is specifically described in combination with Figures 4 to 6 and Figure 22 and Figure 23

[0094] Step 1: Take out the analyzer and the detection plate, and insert the detection plate into the slot from the insertion port of the analyzer.

[0095] Step 2: As the detection plate is inserted, the non-recessed part of the detection plate recognition module will press the keys of the detection switches S1 and / or S2, and the detection switch whose key is pressed will be triggered by the key, and the trigger information of the triggered switches S1 and S2 is transmitted to the single-chip microcomputer.​

[0096] When the detection plate shown in Figure 4 is inserted into the analyzer, the button of the first detection switch S1 and the button of the second detection switch S2 on the circuit board are pressed by the detection plate, the single-chip microcomputer receives the signal combination that S1 and S2 are both triggered, and after signal analysis, the single-chip microcomputer judges that the detection plate inserted in the analyzer at present is used for detecting HCG.

[0097] When the detection plate shown in Figure 5 is inserted into the analyzer, the button of the first detection switch S1 (261) on the circuit board is not pressed by the detection plate, the button of the second detection switch S2 (262) is pressed by the detection plate, the single-chip microcomputer receives the signal combination that S1 is not triggered and S2 is triggered, and after signal analysis, the single-chip microcomputer judges that the detection plate inserted in the analyzer at present is used for detecting LH.

[0098] When the detection plate shown in Figure 6 is inserted into the analyzer, the button of the first detection switch S1 on the circuit board is pressed by the detection plate, the button of the detection switch S2 is not pressed by the detection plate, the single-chip microcomputer receives the signal combination that S1 is triggered and S2 is not triggered, and after signal analysis, the single-chip microcomputer judges that the detection plate inserted in the analyzer at present is used for detecting FSH.

[0099] Step 3: The analyzer starts the test program corresponding to the type of the detection plate.

[0100] Step 4: The test is ended, and the test result is displayed.

[0101] If the single-chip microcomputer is in a sleep state before the detection plate is inserted, the signal that the detection switch is triggered will first wake up the single-chip microcomputer, and then the single-chip microcomputer analyzes the trigger signal of the detection switch to distinguish the detection type of the detection plate.

[0102] If the single-chip microcomputer is in a wake-up state before the detection plate is inserted, the single-chip microcomputer will directly analyze the trigger signal of the detection switch to distinguish the detection type of the detection plate.

[0103] An optional and non-essential step is that the analyzer displays the detection type of the detection plate on the display screen 30 of the analyzer.

[0104] Different designs of the detection plate and the analyzer, some analysis systems have added samples on the detection plate before the detection plate is inserted into the analyzer, and other analysis systems add samples to the detection plate after the detection plate is inserted into the analyzer and the type of the detection plate is confirmed.

[0105] When Figures 4 to 6 the detection plate is inserted into the analyzer, the detection plate will generate Figure 26Two signals of signal 1 and signal 2 are shown. When the concave part of the detection plate recognition module matches the detection switch of the analyzer, the analyzer will generate signal 1 and transmit it to the single-chip microcomputer, and signal 1 will not generate a rising or falling signal, that is, signal 1 is a constant high-level signal. When the non-concave part of the detection plate recognition module matches the detection switch of the analyzer, the analyzer will generate signal 2 and transmit it to the single-chip microcomputer, and when the switch key is pressed by the non-concave area of the recognition module, a falling signal 2 will be generated.

[0106] When the detection switch has the function of starting the analyzer, the recognition module on the detection plate needs to include a non-concave part to generate signal 2, and the single-chip microcomputer is awakened by the change of the signal falling of signal 2. If the recognition module on the detection plate is all concave, the switch of the analyzer cannot be pressed, so the analyzer cannot rely on the recognition module alone to determine whether the test paper has been inserted and to wake up the start. The analyzer needs to add an additional start switch.

[0107] In order to better realize the function of the detection switch as a start switch, in the optimization design of the detection plate as shown in Figure 24 , a non-concave part 151 and a concave part 154 are sequentially arranged on a recognition module, and the non-concave part 151 contacts the detection switch earlier than the concave part 154. Figure 24 During the insertion of the detection plate into the analyzer, the front end of the detection plate recognition module 15 will first press the key of the detection switch 26, and then the detection plate will continue to be inserted into place, and the detection switch will be located at the concave part 154 of the detection plate as shown. Figure 24 The detection switch 26 pressed by the non-concave part 151 will pop out. During the entire insertion process, the analyzer generates a pulse signal that first changes from high level to low level and then changes from low level to high level and transmits it to the single-chip microcomputer, as shown in Figure 26 signal 3. The analyzer detects the falling signal of signal 3 and determines that the detection plate has been inserted and wakes up the analyzer. Then, the analyzer detects the rising signal of signal 3, and the analyzer determines that the detection plate has been inserted into place. At the same time, the analyzer determines the type of the detection plate matched according to the falling signal of signal 3 first and then the rising signal of signal 3. For example, we can set Figure 24 the detection plate shown in the figure for drug detection.

[0108] The detection plate shown in Figure 25 includes two recognition modules, of which the first recognition module includes a concave part 152 at the upper right corner, and the second recognition module sequentially includes a non-concave part 151 and a concave part 154 at the upper left corner, and the non-concave part 151 contacts the detection switch earlier than the concave part 154. Figure 25In the process of inserting the detection plate into the analyzer, the first identification module, i.e. the upper right corner only includes a recess, so the detection switch will not be pressed, and the analyzer detects that the detection switch of the first identification area produces a signal 1 signal. At the same time, the analyzer detects that the detection switch corresponding to the non-recess 151 and another recess 154 in the upper right corner of the second identification module produces a signal 3 signal. When the analyzer single-chip microcomputer detects the two groups of signals with differences, it is judged that the type of the detection plate matched therewith. For example, we can set Figure 25 The detection plate shown is used for analyzing estradiol.
