Description

A quantitative analyzer for colloidal gold test card markings Technical Field

[0001] This utility model relates to the field of colloidal gold detectors, and more specifically, to a quantitative detector capable of identifying colloidal gold test cards. Background Technology

[0002] Currently, colloidal gold test strips or test cards are widely used in food safety testing as rapid detection tools. Existing detection methods generally involve inserting the colloidal gold test card into a detector, which then extracts the results. One example is a laser-induced long-wave infrared colloidal gold test strip quantitative detection device, which includes an infrared imaging module, a plate locking mechanism, a test strip mounting base, a laser clamping plate, a platform support, an outer envelope structure, a data acquisition and transmission module, and a linear laser. The infrared imaging module can be adjusted within the platform support to achieve the optimal imaging position and angle. The linear laser is fixed perpendicular to the test strip mounting base, covering and heating the detection area of ​​the colloidal gold test strip. The infrared imaging module performs thermal imaging of the detection area and transmits the data to a controller, which processes the data and outputs the results.

[0003] However, in current laboratory testing, if a single testing personnel tests multiple colloidal gold test cards in a day, and accidentally mixes up a completed test card with an untested one and inserts it into the testing instrument again, it can easily lead to errors in the results or output incorrect reports. Summary of the Invention

[0004] To overcome the problem in the prior art that it is impossible to confirm whether a test card has been tested, this utility model provides a quantitative detector that can mark colloidal gold test cards, and can mark the test card at the same time as testing it.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a quantitative detector for marking colloidal gold test cards, comprising a housing, a mounting base installed inside the housing with its inlet extending outside the housing, a heater installed inside the housing for heating the test card, a thermal imaging device located above the mounting base with its acquisition port facing the mounting base, a processor installed inside the housing, a display installed on the top surface of the housing, and a marking mechanism installed inside the housing; the processor is electrically connected to the heater, the thermal imaging device, and the display; the marking mechanism includes a marking component and a liquid container; the marking component includes a marking box containing liquid-retaining cotton and a marking pad covering the marking box, the liquid-retaining cotton being in contact with the inner surface of the marking pad, and the marking pad being located at the end of the mounting base away from the inlet; the liquid container is connected to the marking box.

[0006] In the above technical solution, the detection card is inserted into the mounting base through the inlet, and a heater heats the detection area of ​​the detection card on the mounting base. After heating, the thermal imaging device collects the photothermal response signal, generates a thermal image, and transmits it to the processor, which displays the result on the monitor. The liquid tank contains marking ink, which flows into the marking box and is absorbed by the ink reservoir, allowing the marking pad to print the mark. When the detection card is inserted into the mounting base, as the detection card moves to the end of the mounting base, it contacts the marking pad, and the marking pad prints the mark on the end of the detection card.

[0007] Furthermore, the mounting base includes a base plate and side plates mounted on both sides of the base plate, the base plate and the side plates forming a cavity for accommodating the detection card; the marking pad extends into the cavity and is located at the end of the base plate away from the inlet. The marking pad extends into the cavity, ensuring that when the detection card is inserted into the mounting base, the detection card will inevitably contact the marking pad and be marked. Simultaneously, when the detection card is obstructed by the marking pad, it indicates that the action has been completed.

[0008] Furthermore, the shape of the marking pad conforms to the shape of the cavity. Since the shape of the cavity conforms to the shape of the test card, and the marking pad conforms to the shape of the cavity, there is more contact surface between the test card and the marking pad, making the markings on the test card more visible.

[0009] Furthermore, the liquid cartridge is located above the marking box. The ink in the liquid cartridge can flow into the marking box under the influence of gravity.

[0010] Furthermore, the top of the liquid container abuts against the inner top surface of the housing; the top of the liquid container is provided with a liquid filling port; the housing is provided with an injection port communicating with the liquid filling port; a rubber stopper for sealing the injection port is installed at the injection port. By opening the rubber stopper, the liquid container can be removed, and ink can be added to the liquid container through the injection port and the liquid filling port, facilitating subsequent ink addition.

[0011] Furthermore, at least one of the side plates is equipped with a clamping mechanism for holding the test card. The clamping mechanism can fix the test card after it is inserted into the mounting base, making the position of the test card more stable.

[0012] Furthermore, the clamping mechanism includes an elastic element connected to the side plate at one end and a clamping plate connected to the other end of the elastic element. The clamping plate includes a vertical portion and a bent portion located at one end of the vertical portion. The vertical portion is parallel to the side plate, and the bent portion is located near the inlet and bends towards the side plate. The bent portion forms an inclined surface that facilitates the insertion of the detection card. When the detection card is inserted, the elastic element is compressed, and the clamping plate moves towards the side plate. Simultaneously, the elastic potential energy generated by the elastic element presses the detection card through the clamping plate, thereby fixing the detection card within the mounting base.

[0013] Furthermore, the heater is a laser heater; the heater is mounted on the side wall of the housing and located on one side of the mounting base, with the laser emission port of the heater facing the mounting base.

[0014] Furthermore, the thermal imaging device is a thermal imager and is installed on the inner top surface of the housing.

[0015] Furthermore, the housing is divided into a detection cavity and an electrical cavity; the mounting base, the heater, the thermal imaging device, and the marking mechanism are all located in the detection cavity, while the processor is located in the electrical cavity. Since the heater generates heat, placing the processor in the electrical cavity reduces the impact of heat on the processor.

[0016] Compared with existing technologies, the advantages are: by using a marking mechanism, a mark is left on the test card while it is being tested. Even if the operator accidentally mixes up the test card that has been quantitatively tested with the test card that has not been quantitatively tested, the marked card can be quickly identified by checking the mark.

[0026] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0027] Example 1

[0028] Figures 1-4 show an embodiment 1 of a quantitative analyzer for colloidal gold test card marking, including a housing 100, a mounting base 200 installed inside the housing 100 with its inlet extending outside the housing 100, a heater 300 installed inside the housing 100 for heating the test card, a thermal imaging device 400 located above the mounting base 200 with its acquisition port facing the mounting base 200, a processor 500 installed inside the housing 100, a display 600 installed on the top surface of the housing 100, and a device mounted on the housing 500. The marking mechanism is located inside the housing 100; the processor 500 is electrically connected to the heater 300, the thermal imaging device 400 and the display 600 respectively; the marking mechanism includes a marking assembly 700 and a liquid tank 800; the marking assembly 700 includes a marking box 720 containing liquid storage cotton 710 and a marking pad 730 covering the marking box 720, the liquid storage cotton 710 is attached to the inner surface of the marking pad 730, and the marking pad 730 is located at the end of the mounting base 200 away from the inlet; the liquid tank 800 is connected to the marking box 720.

[0029] Specifically, the mounting base 200 includes a base plate 210 and side plates 220 mounted on both sides of the base plate 210. The base plate 210 and side plates 220 form a cavity for accommodating the detection card. The marking pad 730 extends into the cavity and is located at the end of the base plate 210 away from the inlet. The marking pad 730 extends into the cavity, ensuring that when the detection card is inserted into the mounting base 200, the detection card will inevitably contact the marking pad 730 and be marked. Furthermore, when the detection card is obstructed by the marking pad 730, it indicates that the operation has been completed.

[0030] In this embodiment, the shape of the marking pad 730 fits the shape of the cavity. The shape of the cavity fits the shape of the test card, and after the shape of the marking pad 730 fits the shape of the cavity, the test card and the marking pad 730 have more contact surface, and the markings on the test card can be more clearly seen.

[0031] The ink cartridge 800 is located above the marking box 720. Ink in the ink cartridge 800 flows into the marking box 720 by gravity. The top of the ink cartridge 800 abuts against the inner top surface of the housing 100; a filling port is provided on the top of the ink cartridge 800; the housing 100 has an injection port connected to the filling port; a rubber stopper 900 is installed at the injection port to seal it. By opening the rubber stopper 900, the ink cartridge 800 can be removed, and ink can be added to the ink cartridge 800 through the injection port and filling port, facilitating subsequent ink additions.

[0032] The working principle or workflow of this embodiment is as follows: The detection card is inserted into the mounting base 200 through the inlet, and the heater 300 heats the detection area of ​​the detection card on the mounting base 200. After heating, the thermal imaging device 400 collects the photothermal response signal, generates a thermal image, and transmits it to the processor 500. The processor 500 displays the result on the display 600.

[0033] In modern laboratories, after testing test cards, the completed test cards are sometimes not discarded but placed in a designated area. However, due to operator error, a tested test card may be mistakenly placed in the untested test card storage area, or it may be accidentally pushed into the untested test card storage area. Although some test cards have barcodes for identification, it is not immediately possible to tell whether a test card has been tested with the naked eye. Therefore, it is still possible to test test cards repeatedly or to find a completed test card in the untested test card storage area.

[0034] In this embodiment of the detector, the liquid tank 800 contains marking ink. The ink flows into the marking box 720 and is absorbed by the ink reservoir, allowing the marking pad 730 to print a mark. When the test card is inserted into the mounting base 200, as the test card moves to the end of the mounting base 200, it contacts the marking pad 730, and the marking pad 730 prints a mark on the end of the test card. The operator can visually determine whether the test card has completed the test by checking for the presence of a mark.

[0035] The beneficial effects of this embodiment are: by using a marking mechanism, a mark is left on the test card while it is being tested. Even if the operator accidentally mixes up the test card that has been quantitatively tested with the test card that has not been quantitatively tested, the marked card can be quickly picked out by checking the mark.

[0036] Example 2

[0037] Figures 2-4 show an embodiment 2 of a quantitative analyzer for marking colloidal gold test cards. Based on embodiment 1, the difference is that, as shown in Figure 4, at least one side plate 220 is equipped with a clamping mechanism for holding the test card. This clamping mechanism can fix the test card after it is inserted into the mounting base 200, making the position of the test card more stable.

[0038] In this embodiment, the clamping mechanism includes an elastic member 230 connected to the side plate 220 at one end and a clamping plate 240 connected to the other end of the elastic member 230. The clamping plate 240 includes a vertical portion 241 and a bent portion 242 located at one end of the vertical portion 241. The vertical portion 241 is parallel to the side plate 220, and the bent portion 242 is located near the inlet and bends in the direction of the side plate 220. The bent portion 242 forms an inclined surface that facilitates the insertion of the detection card. When the detection card is inserted, the elastic member 230 is compressed, and the clamping plate 240 moves towards the side plate 220. At the same time, the elastic potential energy generated by the elastic member 230 presses the detection card through the clamping plate 240, thereby fixing the detection card in the mounting base 200.

[0039] The remaining features and working principles of this embodiment are consistent with those of Example 1.

[0040] Example 3

[0041] Embodiment 3 of a quantitative analyzer for colloidal gold test card markings differs from Embodiments 1 and 2 in that the heater 300 is a laser heater 300; the heater 300 is mounted on the side wall of the housing 100 and located on one side of the mounting base 200, with the laser emission port of the heater 300 facing the mounting base 200. The thermal imaging device 400 is a thermal imager and is mounted on the inner top surface of the housing 100.

[0042] The remaining features and working principles of this embodiment are consistent with those of Embodiment 1 or 2.

[0043] The thermal imager in this embodiment can also be an infrared thermal imaging device, and the laser heater 300 is an infrared laser heater 300.

[0044] Example 4

[0045] Embodiment 3 of a quantitative analyzer capable of marking colloidal gold test cards differs from Embodiments 1 and 2 in that, as shown in Figure 2, the housing 100 is divided into a detection chamber 110 and an electrical chamber 120. The mounting base 200, heater 300, thermal imaging device 400, and marking mechanism are all located in the detection chamber 110, while the processor 500 is located in the electrical chamber 120. Since the heater 300 generates heat, placing the processor 500 in the electrical chamber 120 reduces the impact of heat on the processor 500.

[0046] In this embodiment, the processor 500 is a Raspberry Pi 4b module. The display 600 is an LCD screen.

[0047] The remaining features and working principles of this embodiment are consistent with those of Embodiment 1 or 2.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
