DETAILED DESCRIPTION OF THE EMBODIMENTS

[0065] The present invention will be described below in detail in conjunction with specific drawings. These specific embodiments are only limited enumeration without departing from the spirit of the present invention, and do not exclude other specific embodiments derived from the combination of the prior art and the present invention by a person of ordinary skill in the art.

[0066] As shown in FIGS. 1 to 6, the detection device 1 includes an upper plate 11, a bottom plate 12, test strip 13 assembled between the upper and bottom plates, a test result reading window 14, and an identification element 15 indicating the type of the detection device, the identification element 15 being used to trigger a detection switch in an analyzer 20 to identify the type of the detection device. Specifically, the identification element 15 identifies the type of the detection device through the presence or absence of a recessed portion and the position of the recessed portion, that is, it identifies the type of the detection device in a way that 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 supporting pad 131, a sample addition pad 132, a label pad 133, a detection pad 134 and a water absorbing pad 135 superposed together and disposed on the supporting pad in sequence from upstream to downstream. After a liquid sample is added to the sample addition pad, the sample flows past the sample addition pad, the label pad, the detection pad and the water absorbing pad sequentially. The test strip is mounted between the upper plate and the bottom plate, and a part of the sample addition pad is located outside the upper and bottom plates to receive the liquid sample. The detection device may further include a cover 16 to cover and protect the sample addition pad exposed to the outside.

[0067] The identification element includes a recessed portion, a non-recessed portion, or a combination of the recessed portion and the non-recessed portion. The type of the detection device is identified through the number and combination of the recessed portion and non-recessed portion in the identification element, and thus to achieve the purpose of identifying the detection type of the detection device. The identification element is provided with at least one recessed portion and/or at least one non-recessed portion.

[0068] The recessed portion and non-recessed portion in the identification element are arranged in many ways, including but not limited to: first, the identification element includes only the non-recessed portion(s), that is, the identification element is one or more non-recessed portions; second, the identification element includes the recessed portion(s), that is, the identification element is one or more non-recessed portions; third, the identification element includes both the recessed portion(s) and the non-recessed portion(s), that is, one or more recessed portions and non-recessed portions are provided, etc.

[0069] The number of the identification element(s) may be one or at least two, for example, two, three, four, etc. The identification element is located on the detection device, particularly on the housing of the detection device, i.e., the identification element is located on the housing formed by closure of the upper plate and the bottom plate. The identification elements are disposed at the front end or on broadside of the housing of the detection device, or are disposed at the front end and on the broadside of the housing simultaneously. The front end described here includes the upper and bottom surfaces of the housing, and also includes the part protruding from the front end of the housing.

[0070] There are many ways of combination of the identification elements, including but not limited to: 1, two identification elements are comprised, which are disposed at different positions on the detection device, respectively; for example, the two identification elements are disposed at the front end or two side walls of the upper plate, wherein one of the identification elements is set as a recessed portion, and the other one is set as a non-recessed portion; or the two identification elements are both set as recessed portions; or the two identification elements are both set as non-recessed portions. 2. Two identification elements are comprised; one identification element is located in the upper right corner of the front end of the upper plate and is set as a recessed portion, and the other identification element is located in the upper left corner of the front end of the upper plate and is set as a non-recessed portion; or, one identification element is located in the upper right corner of the front end of the upper plate and is set as a non-recessed portion, and the other identification element is located in the upper left corner of the front end of the upper plate and is set as a recessed portion. 3. One or more identification elements are comprised, wherein one identification element includes at least one non-recessed portion and one recessed portion, wherein said non-recessed portion is closer to the front end of the detection device than the recessed portion, and the non-recessed portion contacts a detection switch of the analyzer earlier than the recessed portion. 4. Four identification elements are comprised, which are disposed at the front end and two sides of the detection device, respectively.

[0071] In one design solution, as shown in FIGS. 27 and 28, the detection device includes an identification element 15 at the front end of the upper plate 11, there are two setting modes for the identification element: the first mode is that the front end of the upper plate is provided with no recessed portion, i.e., the identification element only includes the non-recessed portion 151, as shown in FIG. 28; the second mode is that the whole front end of the upper plate is set as a recessed portion 152, as shown in FIG. 27.

[0072] In another design solution, as shown in FIGS. 4 to 6, the detection device includes two identification elements 15 located at the front end of the upper board 11. There are three setting modes for the two identification elements: the first mode is that the front end of the upper plate is provided with no recessed portion, that is, both the two identification elements are non-recessed portions, as shown in FIG. 4; the second mode is that there is a recessed portion (the first identification element) in the upper right corner of the upper plate, and there is no recessed portion (the second identification element) in the upper left corner, as shown in FIG. 5; the third mode is that there is no recessed portion (the first identification element) in the upper right corner of the upper plate, and there is a recessed portion (the second identification element) in the upper left corner, as shown in FIG. 6, wherein the second mode and the third mode are the setting way that in the case where the identification elements are set as one recessed portion and one non-recessed portion, the position relationship between the recessed portion and the non-recessed portion is changed.

[0073] The analyzer 20 used in cooperation with the detection device, as shown in FIGS. 7 to 10, includes an upper cover 21, a bottom cover 22, and a circuit board 23 assembled between the upper and bottom covers. The circuit board 23 is fixed in the analyzer through a base 24, the upper cover and the bottom cover are assembled together to form the housing of the analyzer, and a detection device insertion port 28 is formed at the front end. The other side of the base 24 opposed to the circuit board mounting side is provided with a slot 25 for insertion of the detection device. The detection switch 26 used to identify the type of the detection device is mounted on the circuit board, and the base 24 is provided with a through hole 241 at a position corresponding to the detection switch, and after the circuit board is assembled to the base, the button 27 for the detection switch 26 mounted on the circuit board extends through the through hole 241 into the slot 25. After the detection device is inserted into the slot of the analyzer, the identification element 15 of the detection device is located above the button 27 for the detection switch 26. If the part of the identification element 15 corresponding to the detection switch 26 is set as a non-recessed portion, the non-recessed portion of the housing of the detection device will touch the button 27 for the detection switch and press the button to trigger the detection switch 26 to switch on; and if the part of the identification element corresponding to the detection switch is set as a recessed portion, the recessed portion of the housing of the detection device will not touch the button for the detection switch, and the button will not be pressed to trigger the switch to switch on as it is being pressed by the detection device to descend.

[0074] The shape of the button 27 can be set as a slope, a hemisphere, a rectangle or a square, or the like. For example, the side of the button facing the detection device is of a slope surface structure, which is more beneficial for the detection device to push and press the button after it is pushed into the slot and contacts the button.

[0075] The analyzer 20 can be provided with a power-on switch individually. In one design solution, said detection switch 26 for the type of the detection device may also have the function of powering on the analyzer. The detection switch 26 in the analyzer is triggered by the non-recessed portion of the identification element 15 of the detection device to enable the analyzer to power on and identify the type of the detection device. That is, after the detection switch 26 is triggered, it causes the analyzer 20 to power on and start up, and meanwhile the analyzer 20 after starting up can determine the type of the detection device based on the triggering situation of the detection switch.

[0076] The analyzer 20 may further include a detection device ejection assembly. The detection device ejection assembly includes an ejection connection block 291 and an ejection button 292 mounted in the housing of the analyzer.

[0077] In some design solutions, one identification element on the detection device corresponds to one detection switch on the analyzer. For example, two identification elements are disposed on the detection device, and correspondingly, two detection switches are disposed on the analyzer, and the identification elements are in one-to-one correspondence with the switches in position.

[0078] Further specific illustration will be made below with an example of using the different modes of identification elements 15 disposed on the detection device to distinguish an hCG detection device, an FSH detection device and an LH detection device.

[0079] The test strip for analyzing the hCG content in urine is stored in the detection device as shown in FIG. 4. No recessed portion is disposed at a position on the identification element 15 of this detection device corresponding to the button 27 for the detection switch 26 of the analyzer, i.e., the identification element at the front end of the upper plate is wholly a non-recessed portion 151. In the example of FIG. 4, said non-recessed portion is the part of the upper surface of the upper plate 11 that extends horizontally to the front end of the upper plate.

[0080] Test strip for analyzing the LH content in urine is stored in the detection device as shown in FIG. 5. A right recessed portion 152 (first identification element) is disposed at a position on the identification element 15 of this detection device corresponding to the button 271 for the first detection switch 261 of the analyzer, i.e., a recessed structure is disposed in the upper right corner of the front end of the upper plate; no recessed portion is disposed at a position on the identification element 15 of this detection device corresponding to the button 272 for the second detection switch 262 of the analyzer, i.e., a non-recessed portion 151 (second identification element) is disposed at the upper left corner of the front end of the upper plate.

[0081] Test strip for analyzing the FSH content in urine is stored in the detection device as shown in FIG. 6. A left recessed portion 153 is disposed at a position on the identification element 15 of the detection device corresponding to the button for the second detection switch of the analyzer, i.e., a left recessed structure is disposed in the upper left corner of the front end of the upper plate, and no recessed portion is disposed at a position on the identification element 15 of the detection device corresponding to the button for the first detection switch of the analyzer, i.e. a non-recessed portion 151 is disposed in the upper right corner of the front end of the upper plate.

[0082] The depth of the recessed portion is set to ensure at least the bottom of this recessed portion does not touch the button for the detection switch.

[0083] The type of the detection device can be determined by whether the detection switch of the analyzer is pressed by the identification element of the detection device. The analyzer and the detection switch for the type of the detection device will be described in detail below. The tester can also determine the type of the detection device currently in use by directly observing the identification element of the detection device, instead of using the analyzer. As for the detection device of which the detection type is determined by direct observation of the tester, the position of the recessed portion or non-recessed portion of the identification element may not correspond to the detection switch of the analyzer.

[0084] For example, when it is detected by an instrument or observed by human eyes that the identification element of the detection device is wholly non-recessed portions, it determines that the detection device is an HCG detection device; or when it is detected or observed that the identification element of the detection device is only provided with one right recessed portion, it determines that the detection device is anLH detection device; or when it is detected or observed that the identification element of the detection device is only provided with one left recessed portion, it determines that the detection device is an FSH detection device; or when it is detected or observed that the identification element of the detection device is provided with both the right and left recessed portions, it determines that the detection device is an E2 (estradiol) detection device.

[0085] The person skilled in the art can provide different number of identification elements on the detection device, different number of recessed portions on the identification elements, and positions of the identification elements and recessed portions on the detection device according to the number of relevant detection items; and accordingly, different number of detection switches are disposed at corresponding positions on the analyzer to correspond to the identification elements. It is also possible to complete the correspondence between the identification elements and the detection types by the number of the recessed portions, the positions of the recessed portions, or the arrangement and combination of the number of the recessed portions and the positions of the recessed portions. The recessed portion may be designed as other structure with similar functions, such as a notch.

[0086] The LH detection device in FIG. 5 is taken as an example below to further illustrate the identification element of the detection device cooperating with the detection switch of the analyzer to determine the type of the detection device.

[0087] Two detection switches are provided side by side on the circuit board of the analyzer shown in FIGS. 11 to 17, which are a first detection switch 261 and a second detection switch 262, respectively. In order to more clearly express the cooperation between the identification element of the detection device and the detection switch of the analyzer, mounting pieces for mounting the circuit board in the housing of the analyzer are omitted in the example drawings (FIGS. 11 and 12), for example, the base is omitted in these drawings. When the detection device with a right notch is inserted into the analyzer, the part of the identification element corresponding to the second button 271 for the second detection switch 261 of the analyzer is a right recessed portion 152 (first identification element), and the bottom wall of the recessed portion will not contact the first button 271, and the first button 271 will not be pressed to descend in the process of inserting the detection device to the analyzer, so that the first detection switch 261 cannot be triggered by the first button to switch on, and thus the signal given to the singlechip by the first detection switch 261 is always a high level signal (signal 1). The part of the identification element corresponding to the second button 272 for the second detection switch 262 of the analyzer is a non-recessed portion 151 (second identification element), the plate wall of the non-recessed portion will contact the second button 272, and the second button 272 will be pressed by the non-recessed portion to descend in the process of inserting the detection device into the analyzer, so the second detection switch 262 will be triggered by the second button 272 to convert high level at a pin of the singlechip connected with the second detection switch 262 to low level, thus generating a falling edge signal (signal 2). The analyzer can determine that the inserted detection device is an LH detection device after obtaining no change of the first detection switch 261 and the falling edge signal of the second detection switch 262.

[0088] The identification element 15 for the type of the detection device can also be disposed on the broadside of the detection device to determine the type of the detection device through the presence or absence of the recessed portion on the side wall and the position of the recessed portion, as shown in FIGS. 18 to 21. The setting modes of the recessed portion include but not limited to the follows ways: neither of the two side walls of the detection device is provided with a recessed portion; or one side wall of the detection device is provided with a recessed portion and the other side wall is provided with no recessed portion; or the two side walls are each provided with a recessed portion, etc. The identification element of the detection device as shown in FIGS. 18 and 19 is provided with no recessed portion, and the button for the detection switch is correspondingly mounted to the inner side face of the detection switch. In the process of inserting the detection device 1 into the analyzer, the first detection switch 261 and the second detection switch 262 are triggered by the identification elements of the detection device press the buttons for the switches. As shown in FIG. 20 and FIG. 21, the identification element of the detection device is provided with a recessed portion 154 on one side and is not provided with a recessed portion on the other side. In the process of inserting the detection device 1 into the analyzer, the first detection switch 261 will be triggered by the fact that the button for the switch is pressed by the identification element of the detection device, while the second detection switch 262 will not be triggered since it is not pressed by the identification element of the detection device.

[0089] FIG. 22 and FIG. 23 are the working principle of an analyzer of the present invention to identify the type of a detection device. The circuit consists of two branch circuits: a first circuit including a resistor R1, a capacitor C1, a detection switch S1, a VCC power supply terminal, a signal ground and the P0.0 terminal of a singlechip; a second circuit including a resistor R2, a capacitor C2, a detection switch S2, a VCC power supply terminal, a signal ground and the P0.1 terminal of the singlechip. When the detection switch S1 or S2 is not pressed by the button, the voltage across P0.0 and P0.1 of the singlechip is kept in line with the VCC voltage, and the detection switch provides a constant high level signal (signal 1) to the singlechip. When the detection switch S1 or S2 is pressed by the button, P0.0 and P0.1 of the singlechip to which it is connected will be connected to the signal ground, while the voltage across P0.0 and P0.1 will be pulled down by the signal ground and changed from high level to low level, thus generating a falling edge signal (signal 2) to the singlechip.

[0090] The power source of the analyzer can be selected from button cells, alkaline cells, rechargeable lithium cells, solar cells, switching power sources, etc.

[0091] An analysis method for analyzing an analyte in a sample using the detection device and analyzer described in the present invention, includes the following steps: inserting the detection device into the analyzer; triggering at least one detection switch, the triggered detection switch generates an external trigger signal to give to the singlechip. After receiving this trigger signal, the singlechip generates an external interruption to wake up the singlechip. The singlechip waked up from dormancy gives priority to process the interrupt program triggered by the detection switch to determine the type of test strip in the interrupt program. If the button is not pressed as the detection device ejects the analyzer after the singlechip is waked up or as the detection device is incorrect in mounting position or loosen, the detection switch generates a rising edge signal given to the singlechip, so that the detection device position monitoring program of the singlechip is triggered to inform the singlechip of the abnormal position of the detection device. The singlechip monitors the pressed state of the switch in the detection device position monitoring program to determine whether a test strip is mounted in place and whether it is replaced with a test strip of another type. The sample is added to the test strip; the analyzer selects a corresponding algorithm to read the test result of the test strip according to the type of the detection device; and the analyzer gives the detection result.

[0092] The sample analysis method is specifically illustrated by taking the cooperation of the detection device and the analyzer described in FIGS. 4 to 6 as an example in combination with FIGS. 22 and 23.

[0093] Step 1: the analyzer and the detection device are taken out, and the detection device is inserted into the slot through the insertion port on the analyzer.

[0094] Step 2: with the insertion of the detection device, the non-recessed portion of the identification element of the detection device will press the button for the detection switch S1 and/or S2, the detection switch for which the button is pressed is triggered, and the trigger information of triggering the switches S1 and S2 is transmitted to the singlechip.

[0095] When the detection device shown in FIG. 4 is inserted, the buttons for the first detection switch S1 and the second detection switch S2 on the circuit board are pressed together by the detection device, and the singlechip receives a combination of signals that S1 and S2 are both triggered. After signal analysis, the singlechip determines that the detection device currently inserted into the analyzer is for detecting HCG.

[0096] When the detection device shown in FIG. 5 is inserted, the button 271 for the first detection switch S1 (261) on the circuit board is not pressed by the detection device, while the button 272 for the second detection switch S2 (262) is pressed by the detection device, and the singlechip receives a combination of signals that S1 is not triggered and S2 is triggered. After signal analysis, the singlechip determines that the detection device currently inserted into the analyzer is for detecting LH.

[0097] When the detection device shown in FIG. 6 is inserted, the button for the first detection switch S1 on the circuit board is pressed by the detection device, while the button for the second detection switch S2 is not pressed by the detection device, and the singlechip receives a combination of signals that S1 is triggered and S2 is not triggered. After signal analysis, the singlechip determines that the detection device currently inserted into the analyzer is for detecting FSH.

[0098] Step 3: the analyzer starts a test program corresponding to the type of the detection device.

[0099] Step 4: the test ends and the test result is displayed.

[0100] If the singlechip is in a dormant state before insertion of the detection device, the signal indicating the detection switch is triggered will wake up the singlechip first, and then the singlechip will analyze the trigger signal for the detection switch, thus distinguishing the detection type of the detection device; and

[0101] If the singlechip is already in a wake-up state before the detection device is inserted, the singlechip will directly analyze the trigger signal for the detection switch, thus distinguishing the detection type of the detection device.

[0102] The analyzer displays the detection type of the detection device on the display screen 30 of the analyzer is an optional and non-essential step.

[0103] Detection devices and analyzers vary in design. For some analysis systems, a sample has already been added to the detection device before the detection device is inserted into the analyzer; and for other analysis systems, a sample is added to the detection device after the detection device is inserted into the analyzer and the device type is confirmed.

[0104] When the detection device described in FIGS. 4 to 6 is inserted into the analyzer, two signals, i.e., signal 1 and signal 2 as shown in FIG. 26, are generated. When the recessed portion of the identification element of the detection device cooperates with the detection switch of the analyzer, the analyzer generates signal 1 and transmits it to the singlechip, wherein signal 1 does not generate a rising or falling signal, i.e., signal 1 is a constant high level signal. When the non-recessed portion of the identification element of the detection device cooperates with the detection switch of the analyzer, the analyzer generates signal 2 and transmits it to the singlechip, and when the button for the switch is pressed by the non-recessed region of the identification element, a falling signal 2 is generated.

[0105] When the detection switch also has the function of powering on the analyzer, the identification element on the detection device needs to include the non-recessed portion to generate signal 2, and the singlechip wakes up to the power-on function through the change of signal falling of signal 2. If the identification elements on the detection device are both recessed portions, the switch of the analyzer cannot be pressed, so the analyzer cannot determine whether the test strip is already inserted and wake up the power-on function by solely relying on the identification elements, the analyzer needs to add an additional power-on switch.

[0106] In order to better realize the detection switch having the function of the power-on switch, in the optimized design of the detection device in FIG. 24, the non-recessed portion 151 and the recessed portion 154 are disposed on one identification element in sequence, and the non-recessed portion contacts the detection switch earlier than the recessed portion 154. When the detection device described in FIG. 24 is inserted into the analyzer, the foremost end of the identification element 15 of the detection device will first press the button for the detection switch 26. Subsequently, insertion of the detection device continues until it is inserted in place, the detection switch is precisely located in the recessed portion 154 of the detection device shown in FIG. 24, and the detection switch 26 which was previously pressed by the non-recessed portion 151 will be ejected again. Throughout the insertion process, the analyzer generates a pulse signal that changes from high level to low level and then from low level to high level and transmits it to the singlechip, signal 3 as shown in FIG. 26. The analyzer detects the falling signal of signal 3, and then determines that the detection device is already inserted and the analyzer is waked up. Immediately after that, the analyzer detects the rising signal of signal 3, and then determines that the detection device is already inserted in place. At the same time, the analyzer determines the matched type of the detection device based on the fact that signal 3 appears first as a falling signal and then as a rising signal. For example, we can set the detection device shown in FIG. 24 for drug detection.

[0107] The detection device shown in FIG. 25 includes two identification elements, wherein the first identification element includes a recessed portion 152 in the upper right corner, and the second identification element has a non-recessed portion 151 and a recessed portion 154 in the upper left corner in sequence, and the non-recessed portion 151 contacts the detection switch earlier than the recessed portion 154. In the process of inserting the detection device described in FIG. 25 into the analyzer, the first identification element, i.e., the upper right corner only includes a recessed portion, so that the detection switch will not be pressed, and the analyzer detects a signal that what is generated by the detection switch in the first identification area is signal 1. At the same time, the analyzer detects a signal that the detection switch, to which the second identification element (i.e., the non-recessed portion 151 and the other recessed portion 154 in the upper right corner) corresponds, generates signal 3. When the singlechip on the analyzer detects the two groups of signals with differences, it thus determines the matched type of the detection device. For example, we can set the detection device shown in FIG. 25 for analysis of estradiol.
