DETAILED DESCRIPTION

[0022] In the present application, it should be understood that terms such as “including” or “having” are intended to indicate the presence of the disclosed features, numbers, steps, behaviors, components, parts or combinations thereof in the present specification, but do not exclude the possibility of the presence of one or more other features, numbers, steps, behaviors, components, parts or combinations thereof.

[0023] It should also be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] The present application will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0025] As attached Figure 1a and Figure 1b As shown, the self-starting trigger device of the present application includes an insulating carrier 11 and two electrode structures 12, wherein the two electrode structures 12 are arranged on the insulating carrier 11, and the two electrode structures 12 respectively have exposed first parts 121 above the insulating carrier 11, and the two electrode structures 12 respectively have exposed second parts 122 below the insulating carrier 11, and the two electrode structures 12 are insulated from each other.

[0026] In the test state and in the application state, the second portion 122 of the electrode structure 12 is located below the first portion 121 thereof.

[0027] Specifically, the electrode structure 12 can be a metal wire wound on an insulating carrier 11. In the electronic test pen, the second part 122 of the electrode structure 12 contacts the upper surface of the test paper, and the first part 121 of the electrode structure 12 is electrically connected to the reading circuit in the electronic test pen. When the user drops urine on the test paper, as the test paper gradually becomes wet, the resistance between the two electrode structures 12 will decrease. After the reading circuit detects that the resistance value between the two electrode structures 12 is reduced to a sufficiently small value, it will start the circuit for distinguishing the color of the test paper.

[0028] refer to Figure 2 The present application provides a detection method for the above-mentioned type of self-starting trigger device, so as to detect whether the self-starting trigger device can effectively trigger the start of the reading circuit. The method includes the following steps.

[0029] Step S1 : placing the self-starting trigger device on an insulating water-absorbing material, and making the second parts 122 of the two electrode structures 12 contact with the first area of ​​the insulating water-absorbing material.

[0030] For example, combining Figures 3 to 5 , first place the insulating water-absorbing material in the water-absorbing material placement groove, and then Figure 1b The self-starting trigger device is placed in the automatic trigger device placement slot. At this time, the second parts 122 of the two electrode structures 12 are pressed on the water-absorbing material. Since the water-absorbing material is in a dry state at this time, the resistance between the two electrode structures 12 is very large.

[0031] Step S2, dripping a supporting electrolyte into the second region of the insulating water-absorbing material, and continuously detecting the resistance value between the first portions 121 of the two electrode structures 12.

[0032] Combination Figures 3 to 5 The self-starting trigger device does not cover the entire insulating water-absorbing material. The second area of ​​the insulating water-absorbing material is the exposed area for the test liquid (such as urine) to drip into. If the supporting electrolyte is dripped into the exposed area of ​​the insulating water-absorbing material, as the supporting electrolyte diffuses in the insulating water-absorbing material, the resistance value between the two electrode structures 12 will decrease.

[0033] Step S3: judging whether the self-starting trigger device is qualified according to the curve of the change of the resistance value over time.

[0034] Since the change curve of the resistance value between the two electrode structures 12 over time is obtained, it is possible to analyze whether the self-starting trigger device meets the predetermined design specifications. For example, whether the resistance value between the two electrode structures 12 decreases from a predetermined larger value interval to a predetermined smaller value interval within a predetermined time. Thus, it is possible to analyze whether the self-starting trigger device is qualified.

[0035] In this way, non-destructive and rapid detection of the self-starting trigger device can be achieved.

[0036] In some embodiments, judging whether the self-starting trigger device is qualified according to the curve of the change of the resistance value over time includes:

[0037] In the case where the resistance value decreases monotonically over time and then tends to be stable, it is determined that the self-starting trigger device is qualified.

[0038] Of course, more detailed numerical analysis can be performed to further determine whether the initial value of the resistance value is within the preset numerical range, whether the stable value of the resistance value tends to be stable is within the preset numerical range, and whether the time consumed by the resistance value from the beginning to the stability is within the preset numerical range.

[0039] In some embodiments, the insulating water-absorbing material is in the shape of a long sheet, and the first region is closer to one end of the insulating water-absorbing material in the length direction than the second region.

[0040] In this way, the real scene in in vitro diagnostic equipment such as electronic detection pens can be simulated. That is, the insulating water-absorbing material is used to simulate the test paper, the first area of ​​the insulating water-absorbing material simulates the area in contact with the self-starting trigger device in the test paper, and the second area of ​​the insulating water-absorbing material simulates the area in the test paper that receives urine.

[0041] In some embodiments, the insulating water-absorbing material includes: glass fiber.

[0042] In order to implement the aforementioned test method, the present application also proposes a detection fixture for a self-starting trigger device, referring to Figures 3 to 6 The detection fixture includes: a detection table 21, a pressure head that can move up and down, and two test needles;

[0043] A self-starting trigger device placement groove for placing the self-starting trigger device and a water-absorbing material placement groove for placing insulating water-absorbing material are provided on the upper surface of the detection table 21;

[0044] The two test needles are arranged on the pressure head, and the pressure head is used to press down the self-starting trigger device. When the pressure head moves downward to a set position, the second parts 122 of the two electrode structures 12 are in contact with the insulating water-absorbing material placed in the water-absorbing material groove and the first parts 121 of the two electrode structures 12 are in contact with one of the two test needles respectively.

[0045] Specifically, an insulating water-absorbing material is placed in a water-absorbing material placement groove, and then the self-starting trigger device is placed in the self-starting trigger device placement groove, so that the second part 122 of the two electrode structures 12 is in contact with the insulating water-absorbing material. Then the pressure head is controlled to press down so that the two test needles are in contact with the first part 121 of the two electrode structures 12 in a one-to-one correspondence. Then the supporting electrolyte is dripped into the exposed part of the insulating water-absorbing material. At this time, a device capable of measuring resistance (such as a multimeter or a resistance measuring circuit) can be used to measure the change data of the resistance value between the two electrode structures 12, so as to determine whether the self-starting trigger device meets the predetermined design specifications.

[0046] In some embodiments, the detection fixture also includes a test circuit board 24, on which a power supply circuit 241 and a reference resistor 242 are provided, one of the two test pins is electrically connected to the first power supply output terminal of the power supply circuit 241, the other of the two test pins is electrically connected to the first end of the reference resistor 242, and the second end of the reference resistor 242 is electrically connected to the second power supply output terminal of the power supply circuit 241.

[0047] That is, the two electrode structures 12 and the insulating water-absorbing material they contact are equivalent to a variable resistor, which is connected in series with the reference resistor 242, and the two are connected between a fixed voltage source. The resistance value between the two electrode structures 12 can be calculated by measuring the voltage value across the reference resistor 242.

[0048] For example, if a fixed voltage value is directly applied between the two electrode structures 12 and the current value flowing through the two electrode structures 12 is measured, when the two electrode structures 12 are short-circuited, it is easy to cause a short-term excessive current.

[0049] In some embodiments, the water-absorbing material groove is in the shape of a long strip, so as to match the shape of the long strip of insulating water-absorbing material, and the long strip of insulating water-absorbing material simulates the water absorption process of the long strip of test paper.

[0050] In some embodiments, the self-starting trigger device placement groove is connected to the water absorbing material groove, so that the second parts 122 of the two electrode structures 12 can be in good contact with the insulating water absorbing material.

[0051] In some embodiments, the detection fixture further includes a bracket 25, a handle 26, a limiter 27, a limiter column 28 and a connecting bar 29;

[0052] The bracket 25 is disposed on the detection platform 21 and extends upward;

[0053] The limiting member 27 is disposed on the bracket 25 and has a hollow columnar portion at the lower part thereof, the limiting column 28 is inserted into the hollow columnar portion, and the opening directions of the upper and lower openings of the hollow columnar portion are both vertical directions, so as to limit the movable direction of the limiting column 28 to the vertical direction;

[0054] The first end of the limiting column 28 is fixedly connected to the pressure head, and the second end of the limiting column 28 is rotatably connected to the first end of the connecting strip 29;

[0055] The handle 26 is L-shaped, the second end of the connecting strip 29 is rotatably connected to the bending area of ​​the handle 26, the free end of the short side of the handle 26 is rotatably connected to the upper end of the limiting member 27, and the long side of the handle 26 is a hand grip area;

[0056] The second end of the limiting column 28 is rotatably connected to the first end of the connecting strip 29, the second end of the connecting strip 29 is rotatably connected to the bending area of ​​the handle 26, and the free end of the short side of the handle 26 is rotatably connected to the upper end of the limiting member 27. The rotating shaft is parallel and in a horizontal direction.

[0057] When in use, the user rotates the handle 26, causing the bending area of ​​the handle 26 to rotate (its height in the vertical direction will also change), thereby driving the second end (the upper end) of the connecting bar 29 to rotate (its height in the vertical direction will also change), and the first end (the lower end) of the connecting bar 29 drives the limit column 28 to move up and down (because the limit through hole limits the limit column 28 to only move up and down). In this way, the user can manually control the up and down movement of the pressure head.

[0058] Based on the same inventive concept as the above embodiment, Figure 7 The embodiment of the present application also provides a detection system, including the aforementioned detection fixture, and the detection system also includes: a measurement module 31 and a data processing module 32, the measurement module 31 is used to continuously measure the resistance value between the two test needles, and the data processing module 32 is used to determine whether the self-starting trigger device is qualified according to the change curve of the resistance value over time.

[0059] The measuring module 31 is, for example, a multimeter, and the data processing module 32 is, for example, a computer.

[0060] The measuring module 31 may directly measure the resistance value between the two electrode structures 12 or measure it indirectly.

[0061] For example, when the detection fixture also includes a test circuit board 24, a power supply circuit 241 and a reference resistor 242 are provided on the test circuit board 24, one of the two test pins is electrically connected to the first power supply output end of the power supply circuit 241, the other of the two test pins is electrically connected to the first end of the reference resistor 242, and the second end of the reference resistor 242 is electrically connected to the second power supply output end of the power supply circuit 241, the measurement module 31 is specifically used to measure the voltage across the reference resistor 242 in real time to infer the resistance value between the two test pins 23, and the data processing module 32 is specifically used to determine whether the self-starting trigger device is qualified according to the change curve of the voltage across the reference resistor 242.

If these changes and modifications fall within the scope of the claims of this application and their equivalents, the intention of this application also includes these changes and modifications.
