Description

Technical Field

[0001] This utility model relates to the field of HPV screening technology, specifically an auxiliary device that facilitates the placement and scanning of HPV membrane strips. Background Technology

[0002] HPV strips are a detection tool based on immunodiagnostic technologies (such as enzyme-linked immunosorbent assay (ELISA) or immunoblotting). They are mainly used to quickly detect the presence of antibodies against human papillomavirus (HPV) in human samples (such as serum, secretions, etc.) or to directly detect whether the sample contains HPV antigens. When the sample to be tested comes into contact with the strip, if the sample contains the corresponding antibody or antigen, it will specifically bind to the components on the strip, and then the result will be presented through a color reaction, thereby determining whether HPV infection has occurred.

[0003] The scanner uses optical principles to precisely quantify the color-developing area on the membrane strip, converting the depth of the strip color into a numerical signal for scanning and comparison with a preset threshold, thus avoiding human error. It is especially suitable for identifying weak positive results. Many testing strips (such as immunochromatographic test strips) use nitrocellulose or cellulose acetate membranes. These materials have a porous structure and are highly hydrophilic. During the testing process, after absorbing liquid (such as sample or buffer solution), the membrane strip will swell and deform due to water absorption, which may lead to local or overall bending. If the bending causes the membrane strip to bend during subsequent scanning, it may obstruct the detection area, affecting the acquisition of light signals during instrument scanning and causing misinterpretation of results. In other words, the image may be distorted, reflective, or locally blurred during barcode scanning, affecting the image recognition algorithm's interpretation of information. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an auxiliary device for facilitating the placement and scanning of HPV film strips, thus solving the problems mentioned in the background section.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for facilitating the placement and scanning of HPV film strips, comprising a base and a detachable shelf mounted on the top of the base. A support strip is fixedly connected to the top of the shelf, and a clamping assembly for positioning the end of the film strip is also provided on the top of the shelf. The clamping assembly includes a support and a rotating shaft rotatably inserted into the support. A connecting rod is fixedly connected to each end of the rotating shaft, and a pressure strip is fixedly connected to the end of the connecting rod away from the rotating shaft.

[0006] Preferably, the support has a cavity inside, the rotating shaft passes through the cavity, and an elastic compression assembly is fixedly installed at the bottom of the cavity. The elastic compression assembly includes two guide rods fixed to the bottom wall of the cavity and an arc-shaped pressure block slidably sleeved on the two guide rods. The arc-shaped end of the arc-shaped pressure block is always in contact with the rotating shaft. A spring is fixedly connected between the bottom of the arc-shaped pressure block and the cavity, and the spring is sleeved on the guide rod.

[0007] Preferably, each of the four corners of the bottom of the shelf is fixedly connected with a pin, and each of the four corners of the top of the base is provided with a hole, and the pin is inserted into the hole.

[0008] Preferably, a vertically arranged bracket is fixedly connected to the rear side wall of the shelf, and a scanner is fixedly connected to the upper end of the bracket.

[0010] Preferably, the support strip has a flat plate structure.

[0011] (III) Beneficial Effects This invention provides an auxiliary device for facilitating the placement and scanning of HPV film strips, which has the following beneficial effects: 1. In this utility model, the HPV film strip after testing is placed on the support strip, and then the pressure strip is rotated so that the two pressure strips are pressed and fixed to the end of the HPV film strip, so that the HPV film strip is in a relatively flat state. The information of the color band in the detection area can be scanned and recorded by the scanner, ensuring the accuracy and interpretability of the color band in the detection area, improving the clarity of the image, and ultimately improving the accuracy of the test results.

[0012] 2. In this utility model, during the rotation of the pressure bar, the arc-shaped end of the arc-shaped pressure block is always in contact with the rotating shaft due to the elastic support force of the spring, thereby increasing the clamping force on the rotating shaft and ensuring that the pressure bar can maintain its current state at any angle. Secondly, matte silicone is used, and black light-blocking filler is added to control the reflectivity to below 5%, preventing the membrane strip detection area from being affected by reflection or light spots. At the same time, it also avoids damage to the membrane strip due to excessive pressure on the pressure bar. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figure 1 , Figure 3 This utility model provides a technical solution: an auxiliary device for facilitating the placement and scanning of HPV film strips, including a base 5 and a shelf 1 detachably installed on the top of the base 5. A support strip 2 is fixedly connected to the top of the shelf 1, and a pressing component 3 for positioning the end of the film strip is also provided on the top of the shelf 1. The pressing component 3 includes a support 34 and a rotating shaft 33 rotatably inserted on the support 34. A connecting rod 32 is fixedly connected to each end of the rotating shaft 33, and a pressure strip 31 is fixedly connected to the end of the connecting rod 32 away from the rotating shaft 33.

[0017] After the colorimetric detection is completed, the HPV film strip is placed on the support strip 2, and then the pressure strip 31 is rotated. The pressure strip 31 rotates around the pivot 33, so that the two pressure strips 31 are pressed and fixed to the ends of the HPV film strip, making the HPV film strip in a relatively flat state. Then the scanner 8 is started, and the information of the colorimetric strip in the detection area can be scanned and recorded by the lens of the scanner 8, ensuring the accuracy and interpretability of the colorimetric strip in the detection area, improving the clarity of the image, and ultimately improving the accuracy of the detection results. The colorimetric strip in the detection area is set in the middle of the HPV film strip, so the pressure strip 31 will not obstruct the detection area.

[0018] See Figure 4 and Figure 5The support 34 has a cavity 341 inside, and the rotating shaft 33 passes through the cavity 341. An elastic compression assembly 4 is fixedly installed at the bottom of the cavity 341. The elastic compression assembly 4 includes two guide rods 43 fixed to the bottom wall of the cavity 341 and an arc-shaped pressure block 41 slidably sleeved on the two guide rods 43. The arc-shaped end of the arc-shaped pressure block 41 is always in contact with the rotating shaft 33. A spring 42 is fixedly connected between the bottom of the arc-shaped pressure block 41 and the cavity 341. The spring 42 is sleeved on the guide rods 43.

[0019] During the rotation of the pressure strip 31, the arc-shaped end of the arc-shaped pressure block 41 is always in contact with the rotating shaft 33 due to the elastic support force of the spring 42, which increases the clamping force on the rotating shaft 33. This ensures that the pressure strip 31 can maintain its current position at any angle; that is, it ensures that the pressure strip 31 can stably clamp the end of the HPV film strip, so that the film strip is in a flat state. See Figure 2 Each of the four corners of the bottom of the shelf 1 is fixedly connected with a pin 6, and each of the four corners of the top of the base 5 is provided with a socket 501, into which the pin 6 is inserted.

[0020] The shelf 1 and the base 5 can be disassembled through the engagement of the pin 6 and the socket 501. Therefore, after the HPV membrane strip is identified, the shelf 1 and the support strip 2 can be cleaned to thoroughly clean the sample residue, dust or reagent stains on the surface (such as wiping the surface with a 75% ethanol cotton ball) to ensure a clean state and avoid affecting the next use.

[0021] Reference Figure 1 A vertically mounted bracket 7 is fixedly connected to the rear side wall of the shelf 1, and a scanner 8 is fixedly connected to the upper end of the bracket 7.

[0022] The information of the color bands in the detection area can be scanned and recorded by the lens of scanner 8; in addition, for the model of scanner 8, you can choose the HybriMax Reader from KEP Biotech, which scans the color spots with a high-resolution camera and automatically identifies the HPV genotyping results. This is an existing product, so I will not go into details.

[0023] See Figure 4 The connecting rod 32 is perpendicular to the rotating shaft 33 and the pressure strip 31 respectively, and the end of the pressure strip 31 is fixedly connected with matte silicone.

[0024] The flexible material of matte silicone also avoids damage to the membrane strip due to excessive pressure of the pressure strip 31; and black light-shielding filler (such as carbon black, concentration 5%-8%) is added to the surface of matte silicone to control the reflectivity below 5% to prevent the membrane strip detection area from being affected by reflection or light spots.

[0025] See Figure 2Support bar 2 is a flat plate structure.

[0026] The main purpose of the support strip 2 is to support the HPV film strip. The support strip 2 adopts a flat plate structure, which makes the support surface of the flat plate structure fully fit with the bottom surface of the HPV film strip, ensuring that the film strip detection area and the light source lens of the scanner 8 remain relatively perpendicular, that is, the image of the film strip detection area can be normally recognized by the scanner 8.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
