Description

Technical Field

[0001] The utility model relates to the field of test paper scanning detection, in particular to a test paper detector. Background Art

[0002] Colloidal gold immunochromatography is currently the most commonly used rapid analysis technology in biomedical testing. It can be used for a variety of diseases such as viral antigen or antibody detection, hormone detection, and tumor marker detection. With the development of medical technology, colloidal gold test strips are increasingly used in life and hospitals due to their advantages of simple use, convenience, and rapid detection. The test results of colloidal gold test strips are generally judged by the operator through visual observation of the color of the quality control line and measurement line of the test strip. However, in large hospitals, a large number of tests are faced every day. If the test results are visually determined by the test strips, it will not only take a lot of time, but also the quality control line and measurement line of each test strip have different colors. The test results are often unclear, which may lead to inaccurate visual results.

[0003] To this end, the prior art provides a test strip detector, which has multiple scanning stations for loading and scanning the test results of single-strip test strips. In this way, the test strip detector can synchronously read the test results of multiple single-strip test strips, but cannot be used to read the test results of multi-strip test strips, and has a low scope of application. In addition, the test strip detector needs to be manually loaded and unloaded from each scanning station one by one before and after use, which is cumbersome and time-consuming.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The utility model provides a test paper detector, which is used to solve the problem of how to improve the application range and use convenience of the detector for different test papers.

[0036] See also Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a three-dimensional diagram of the test paper detector in the first state in the embodiment. Figure 2 It is a three-dimensional diagram of the second state of the test paper detector in the embodiment, Figure 3 It is a stereoscopic diagram of the driving device, the scanning device and the tray in the embodiment at a first viewing angle. The test paper detector includes a housing 1, a driving device 2 and a scanning device 3.

[0037] The housing 1 has at least two first scanning stations 11 and a second scanning station 12 . The first scanning station 11 is used for placing single-joint test strips 7 , and the second scanning station 12 is used for placing multi-joint test strips 5 or special-shaped test strips 6 .

[0038] The driving device 2 is installed on the shell 1 and includes an abutment member 22, which is used to abut against the single-link test paper 7, and there is friction between the abutment member 22 and the single-link test paper 7, and the friction is used to link the single-link test paper 7 to move into or out of the first scanning station 11.

[0039] The scanning device 3 is installed at the first scanning station 11 and the second scanning station 12 of the housing 1 , and is used to scan the test papers on the first scanning station 11 and the second scanning station 12 .

[0040] When the test paper detector of the above technical solution is in use, the scanning device 3 can synchronously scan the test results of the single-joint test paper 7 on each first scanning station 11, and the test results of the multi-joint test paper 5 or the special-shaped test paper 6 on each second scanning station 12, which greatly improves the applicability of the test paper detector to different test papers; and before and after the test paper detector is used, the driving device 2 can automatically move all the single-joint test papers 7 into or out of the first scanning station 11 through the friction between the abutment 22 and the single-joint test paper 7, without the need to manually install and remove the test papers from each scanning station one by one, the operation is simple and time-saving, and the convenience and efficiency of use of the test paper detector are greatly improved.

[0041] The number of the above-mentioned scanning devices 3 can be one or more. One scanning device 3 can synchronously scan the test papers on all the first scanning stations 11 and all the second scanning stations 12, or multiple scanning devices 3 can scan the test papers on the first scanning station 11 and the second scanning station 12 respectively.

[0042] The above-mentioned scanning device 3 can use an existing test paper scanning device. The existing test paper scanning device uses LED lights and high-precision silicon photocells. Based on the principle that different colors have different absorption rates for a certain band of the spectrum, the test results of the test paper can be read. Specifically, the light emitted by the LED light source is respectively irradiated onto the quality control line and the measurement line of the colloidal gold test paper, and then reflected onto the silicon photocell. The silicon photocell obtains the ratio of the quality control line and the measurement line based on the light intensity reflected by the test paper to obtain the test result of the test paper. Compared with visual inspection, the test paper scanning device greatly improves the accuracy of the reading results.

[0043] See also Figure 1 and Figure 3 As shown, in one embodiment of the housing 1, the housing 1 includes a tray 13, and the tray 13 has a slide 14, the slide 14 is used to place the single-link test paper 7 and limit the moving direction of the single-link test paper 7, and the scanning device 3 faces the notch of the slide 14, and can scan the test result of the test paper in the slide 14 through the notch of the slide 14. The driving device 2 is configured to drive the test paper to move along the slide 14 toward or away from the scanning device 3, so as to move the test paper into or out of the first scanning station 11. In this way, the slide 14 can limit the moving direction of the test paper, and the auxiliary driving device 2 can quickly and accurately move the test paper into or out of the first scanning station 11, so that the scanning device 3 can scan the test result of the test paper.

[0044] See also Figure 1 and Figure 3 As shown, in one embodiment of the tray 13, a positioning structure 4 is provided in the slide slot 14 of the tray 13, and the positioning structure 4 is used to fix the position of the test paper in the slide slot 14, so as to position the test paper on the first scanning station 11. In this way, the length, width and depth dimensions of the slide slot 14 are designed to be larger in the test paper detector, so that the slide slot 14 can accommodate single-link test papers 7 of most sizes on the market, thereby further improving the application range of the test paper detector, and the positioning structure 4 can fix the test paper in the slide slot 14, so as to avoid the test paper from being offset during the scanning process, thereby affecting the accuracy of the scanning device 3 reading the test paper test results.

[0045] See also Figure 5 As shown, Figure 5The figure is a three-dimensional diagram of the tray in the embodiment. In one embodiment of the positioning structure 4, the positioning structure 4 includes a limiting protrusion 41 and at least two elastic arms 42. The elastic arms 42 can be integrally connected or welded to the groove wall and groove bottom of the slide groove 14, and respectively abut the side and bottom surfaces of the test paper. The limiting protrusion 41 can be integrally connected or welded to the groove wall of the slide groove 14, and abut the top surface of the test paper. In this way, the limiting protrusion 41 and the elastic arm 42 cooperate to fix the single-link test paper 7 of different widths and thicknesses in the upper and lower positions and left and right positions in the slide groove 14, further improving the application range of the test paper detector.

[0046] The elastic arm 42 may be disposed only on the bottom of the slide slot 14 and one side wall of the slide slot 14 , or may be disposed on the bottom of the slide slot 14 and two opposite side walls of the slide slot 14 .

[0047] See also Figure 5 As shown, on the basis of the above embodiment, at least two elastic arms 42 are distributed on both sides of the groove wall of the slide groove 14, and the elastic arms 42 of the groove wall of the slide groove 14 are spaced apart along the extension direction of the slide groove 14. In this way, the more elastic arms 42 there are on one side of the groove wall of the slide groove 14, the better the fixing effect of the test paper, especially for the test paper with a longer length. The longer the test paper, the easier it is to deflect. The test paper can be effectively fixed by more than two elastic arms 42 to prevent the test paper from deflecting in the slide groove 14.

[0048] See also Figure 3 As shown, in one embodiment of the driving device 2, the driving device 2 also includes a first motor 21, and the abutment member 22 can be a rotating member such as a driving wheel. The first motor 21 can be installed in the housing 1 by screwing or welding, and is connected to the driving wheel by transmission. The first motor 21 is configured to drive the driving wheel to rotate, and each chute 14 is relatively distributed with at least one driving wheel position. The driving wheel abuts against the test paper on the corresponding chute 14, and the driving wheel is used to drive the test paper to move into or out of the first scanning station 11 along the chute 14. In this way, when the first motor 21 is started, it can drive the driving wheel to rotate, and the driving wheel drives the test paper to move into the first scanning station 11 or return to its original position through the friction between the driving wheel and the test paper, thereby realizing automatic disassembly and assembly of the test paper, which greatly improves the convenience of use of the test paper detector.

[0049] The abutment member 22 can be not only a rotating member such as a driving wheel, but also a linear displacement member such as a slider. In this way, the first motor 21 drives the slider to move, and the slider drives the test paper to move into the first scanning station 11 or return to its original position through the friction between the slider and the test paper.

[0050] In the present embodiment, each slide slot 14 has two driving wheels positioned opposite to each other, and a clearance gap 23 is provided between the two driving wheels for allowing the observation window of the test paper to pass through, thereby preventing the driving wheel from contacting the NC film of the test paper that is exposed through the observation window, thereby affecting the detection result of the test paper; the driving wheels of each slide slot 14 are integrally connected or welded to the same rotating shaft 24, and the motor shaft of the first motor 21 is transmission-connected to the rotating shaft 24 of the driving wheel through a reversing bevel gear set. In this way, when the first motor 21 is started, it can drive the rotating shaft 24 to rotate, thereby driving the driving wheels of each slide slot 14 to rotate synchronously, thereby greatly saving the driving cost.

[0051] See also Figure 4 As shown, Figure 4 2 is a stereoscopic diagram of the driving device, scanning device and tray in the embodiment at a second viewing angle. On the basis of the above embodiment, the driving device 2 further includes a second motor 25 and a screw 26. The second motor 25 can be screwed or welded in the housing 1. The motor shaft of the second motor 25 can be connected to the screw 26 by welding or pin connection. The tray 13 is slidably installed in the housing 1 along the extension direction of the slide 14, and the screw 26 is threadedly connected to the tray 13. In this way, when the second motor 25 is started, it can drive the screw 26 to rotate, and the screw 26 drives the tray 13 to slide along the extension direction of the slide 14, so that the tray 13 is partially moved out of the housing 1 or returned to its original position, so that the user can put the test paper into or take it out of the slide 14. In combination with the first motor 21 and the driving wheel, the test paper and the tray 13 can be moved into or out of the housing 1 together, so that the test paper can be automatically disassembled and assembled at the first scanning station 11.

[0052] The first motor 21 and the second motor 25 may both use existing stepping motors.

[0053] See also Figure 1 As shown, in one embodiment of the housing 1, a scanning window 15 is provided on the top of the housing 1, and the scanning window 15 of the housing 1 is configured as a second scanning station 12, and the scanning range of the second scanning station 12 is greater than the scanning range of the first scanning station 11. Since the scanning range of the second scanning station 12 is large, the test paper does not need to be positioned at the second scanning station 12, and the test paper is directly placed on the top of the housing 1, and the observation window of the test paper is aligned with the scanning window 15 to scan the test result of the test paper. This detection method is more flexible and convenient, and is more suitable for reading the test results of multiple or special-shaped test papers 6 of different sizes and shapes, wherein the scanning window 15 can scan all the observation windows aligned with the scanning window 15, and read multiple test results at one time.

[0054] The test paper detector also includes a controller and a position sensor (not shown in the figure). The controller is electrically connected to the position sensor and the drive device 2. The position sensor corresponds to each chute 14 and is used to sense the position of the test paper in the corresponding chute 14 and send a move-in signal or an in-position signal to the controller, wherein when the controller receives the move-in signal, the drive device 2 is controlled to start and move the test paper into the first scanning station 11. When the controller receives the in-position signal, the drive device 2 is controlled to shut down and keep the test paper in the first scanning station 11. In this way, before the test, when the test paper is outside the first scanning station 11, the position sensor sends a move-in signal to the controller, and the controller controls the drive device 2 to move the test paper into the first scanning station 11. When the test paper moves into or approaches the first scanning station 11, the position sensor sends an in-position signal to the controller, and the controller controls the drive device 2 to shut down, stop moving the test paper, and position the test paper in the first scanning station 11.

[0055] On the basis of the above embodiment, the housing 1 also has a data transmission port (not shown) for connecting to an external terminal device. The controller is electrically connected to the data transmission port, and the controller is also electrically connected to the scanning device 3. The controller controls the driving device 2 to be turned off and controls the scanning device 3 to start, scan the test results of the test paper, and the scanning device 3 feeds back the scanning results to the controller. The controller automatically imports the test paper detection data obtained by scanning into the terminal device through the data transmission port, which is convenient for data processing, viewing and recording; at the same time, the controller controls the driving device 2 to start, move the test paper out of the first scanning station 11, and return it to its original position.

[0056] The test strip detector also includes a label scanning device (not shown in the figure), which can scan the QR code on the test strip. The controller is also electrically connected to the label scanning device, and the controller imports the test strip detection data and the QR code data into the terminal device through the data transmission port for identification and traceability. The label scanning device can use an existing QR code label scanning device.
