Abstract
Description
Technical Field
[0001] This utility model relates to the field of reagent plate technology, specifically to a single-hole multi-connection reagent plate. Background Technology
[0002] A reagent strip is a common testing device used in routine testing. Various tests, such as COVID-19 testing, hepatitis B positive testing, and pregnancy testing, have their corresponding reagent strips. The common structure of a reagent strip consists of a test sample placement area and a test indicator area.
[0003] However, in practical use, traditional reagent strips can usually only monitor and judge a single analyte. This means that when testing the same substance for multiple different purposes, samples need to be taken separately and placed on a dedicated reagent strip, which is inconvenient. In addition, the distance between the test item and the analyte placement area varies for different test items on a few reagent strips, which may result in different amounts of analyte coming into contact with each test item, and thus may affect the corresponding test results. Moreover, the size and position of the analyte placement area in traditional reagent strips are relatively fixed. When performing a single test, a small amount of analyte can be tested, but when performing multiple tests, more test material is needed, thus requiring a larger holding space. In addition, when testing different analytes, the sample taken on one side is prone to excessive liquid, which may lead to overflow. Utility Model Content
[0004] The purpose of this invention is to provide a single-well multi-reagent plate that solves the problems of uneven distribution of analytes affecting detection results and relatively fixed analyte capacity, which can easily lead to overflow or insufficient solution.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-hole multi-connector reagent plate, comprising a box body, a receiving hopper, and connecting cotton pads, wherein a receiving hopper is installed at the top of one end of the box body, a receiving cylinder is provided at the bottom of the receiving hopper, and multiple connecting cotton pads are provided on the side of the box body away from the receiving hopper.
[0006] A central hole is provided at the top center of the container, and a collar is sleeved around the outer wall of the container.
[0007] The bottom center of the container hopper is connected to the top of the container cylinder, and the outer wall of the container cylinder is provided with multiple conduits in a circumferential manner.
[0008] A receiving box is installed at the bottom end of the connecting cotton pad near the conduit, and a detection strip is provided at the end of the connecting cotton pad away from the receiving box.
[0009] Preferably, the top of the box is fitted with a cover plate, and the inside of the cover plate and the top of the detection strip are provided with rectangular holes, and strip-shaped convex mirrors are installed inside the rectangular holes.
[0010] Preferably, the center of the receiving hopper is inclined to the bottom in a perforated shape, and the outer edge of the receiving hopper is tightly fitted with the inner wall of the collar.
[0011] Preferably, the top edge of the collar is inclined away from the receiving hopper, and the top of the cover plate has a through hole corresponding to the collar, with the outer edge of the collar and the through hole inside the cover plate tightly fitted together.
[0012] Preferably, the bottom of the receiving cylinder is closed, the inner diameter of the receiving cylinder is larger than the inner diameter of the central hole, the interior of the receiving cylinder is in communication with the conduit, and the end of the conduit away from the receiving cylinder is inclined to the bottom.
[0013] Preferably, one end of the connecting cotton pad is connected to the receiving box, the inside of the box has a receiving groove corresponding to the receiving box, and the bottom of the outer wall of the connecting cotton pad is fixed to the box.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] 1. The receiving hopper is interconnected with the receiving cylinder through a central hole, allowing materials to easily collect from the hopper into the central hole and then flow into the receiving cylinder, preventing random flow. Furthermore, because the outer wall of the receiving cylinder is surrounded by multiple conduits, when placed horizontally, the material solution inside the receiving cylinder can easily and evenly flow into each conduit, maintaining the same solution concentration in each conduit. Additionally, because the ends of the conduits away from the receiving cylinder slope downwards, backflow of the material solution inside the conduits is effectively prevented. During use, the solution can be stored in a receiving tank, ensuring sufficient solution for different detection strips.
[0016] 2. The top of the container allows for the collection of material solutions. When there is too much material to be tested, the solution can be easily stored in the bottom container. The collar can also be easily pulled upwards to move it upwards, thus blocking the top edge of the container and preventing the material solution from overflowing. This facilitates the placement and addition of more solution for convenient testing. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figure 1-5 The single-well multi-reagent plate shown includes a box body 1, a container 2, and connecting cotton pads 3. The container 2 is installed at the top of one end of the box body 1, and a container cylinder 4 is provided at the bottom of the container 2. Multiple connecting cotton pads 3 are provided inside the box body 1 on the side away from the container 2. A central hole 201 is opened at the center of the top of the container 2, and a collar 202 is sleeved around the outer wall of the container 2. The center of the bottom of the container 2 is connected to the top of the container cylinder 4, and multiple conduits 401 are arranged around the outer wall of the container cylinder 4. A container box 302 is installed at the bottom end of the connecting cotton pad 3 near the conduits 401, and a detection strip 301 is provided at the end of the connecting cotton pad 3 away from the container 2.
[0027] like Figure 1 , Figure 5As shown, a cover plate 101 is snapped onto the top of the box 1. Rectangular holes are opened inside the cover plate 101 and at the corresponding positions on the top of the detection strip 301. A strip-shaped convex mirror 102 is installed inside each rectangular hole. The center of the receiving hopper 2 is inclined to the bottom in a funnel shape. The outer edge of the receiving hopper 2 is tightly fitted with the inner wall of the collar 202. The top edge of the collar 202 is inclined away from the receiving hopper 2. A through hole corresponding to the collar 202 is opened on the top of the cover plate 101. The outer edge of the collar 202 is tightly fitted with the through hole inside the cover plate 101. The material solution is collected through the funnel-shaped top of the receiving hopper 2. At the same time, when there is too much material to be tested, the solution can be easily stored through the receiving box 302 at the bottom. The collar 202 can also be easily pulled to the top, thereby moving the collar 202 to the top and blocking the top edge of the receiving hopper 2 to prevent the material solution from overflowing.
[0028] like Figure 3 , Figure 4 As shown, the bottom of the container 4 is closed, and the inner diameter of the container 4 is larger than the inner diameter of the central hole 201. The inside of the container 4 is connected to the conduit 401, and the end of the conduit 401 away from the container 4 is inclined to the bottom. Multiple conduits 401 are arranged around the outer wall of the container 4. Thus, when placed in a horizontal position, the material solution inside the container 4 can flow conveniently and evenly to the multiple conduits 401 respectively, keeping the solution inside different conduits 401 the same. At the same time, since the end of the conduit 401 away from the container 4 is inclined to the bottom, the reverse flow of the material solution inside the conduit 401 can also be effectively avoided.
[0029] like Figure 2 , Figure 4 As shown, one end of the connecting cotton pad 3 is connected to the receiving box 302. The inside of the box body 1 is provided with a receiving groove corresponding to the receiving box 302. The bottom of the outer wall of the connecting cotton pad 3 is fixed to the box body 1. It reaches the receiving box 302 at the bottom through the conduit 401. The connecting cotton pad 3 connects the detection strip 301 to the receiving box 302, so that detection can be performed. At the same time, during observation, the changes of the detection strip 301 can be easily viewed through the strip convex lens 102 to better reflect its detection status.
[0030] In use, the material or solution to be tested can be conveniently poured into the container 2, allowing the material to pass through the central hole 201 into the container cylinder 4, and then through the conduit 401 into the bottom container 302. The detection strip 301 is connected to the container 302 via the connecting cotton pad 3, enabling testing. During observation, changes in the detection strip 301 can be easily observed through the convex bar 102 to better reflect the testing status. Furthermore, since the container 2 is connected to the container cylinder 4 through the central hole 201 during testing, the material can easily flow from the container 2 towards the center... The solution collected through the orifice 201 flows into the container 4, preventing random flow. Since the outer wall of the container 4 is surrounded by multiple conduits 401, when placed in a horizontal position, the material solution inside the container 4 can easily and evenly flow into the multiple conduits 401 respectively, keeping the solution inside different conduits 401 the same. At the same time, since the end of the conduit 401 away from the container 4 is inclined to the bottom, it can also effectively prevent the material solution inside the conduit 401 from flowing backward. In addition, the solution can be stored in the container 302 during use, so that different detection strips 301 have enough solution for detection.
[0031] During use, the corresponding material solution can be added into the container 2. The material solution can be collected through the top of the funnel-shaped container 2. When there is too much material to be tested, the solution can be conveniently stored through the bottom container 302. At the same time, the collar 202 can be easily pulled to the top, thereby moving the collar 202 to the top edge of the container 2 to prevent the material solution from overflowing. This makes it convenient to put in and add more solution, and facilitates testing.
[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
