Abstract
Description
Technical Field
[0001] This utility model relates to a reagent kit, specifically a plasma separation and detection reagent kit. Background Technology
[0002] Clinically, disease diagnosis is usually made by measuring the concentration or presence of certain substances in the blood. Common blood testing methods (such as paper chromatography) require a solid-phase membrane or membrane pad as reagent support, and the color change is then observed to determine the level of the analyte in the blood. Because whole blood contains a large number of red blood cells, giving it a red or dark red color, it is difficult or impossible to directly interpret the test results if whole blood is used. Therefore, in clinical testing, fresh plasma must first be separated from whole blood before testing.
[0003] Currently, all diagnostic reagent kits on the domestic and international markets are prone to scattering after opening due to relatively large usage volumes, easily becoming mixed up with other kits, making them inconvenient to use and manage. Therefore, those skilled in the art have proposed a plasma separation and detection kit to address the problems mentioned above. Utility Model Content
[0004] The purpose of this invention is to provide a plasma separation and detection kit to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A plasma separation and detection kit includes several kit housings and an outer housing. The kit housings are placed inside the outer housing. A guide limiting plate is fixedly connected to the inner side of the outer housing. A squeezing block is fixedly connected to the end of each kit housing. A guide notch is formed between the kit housing and the squeezing block. The guide notch slides with the guide limiting plate. The outer housing has a placement hole for inserting the squeezing block. A thrust assembly for pushing the squeezing block is also connected to the outer housing.
[0007] As a further embodiment of this utility model: two sets of guide limiting plates are provided, symmetrically arranged inside the outer box, and a limiting end plate is fixedly connected between the two guide limiting plates, with placement holes opened between the guide limiting plates and the outer box.
[0008] As a further embodiment of this utility model: the thrust assembly has a sliding push plate, which is slidably connected to the guide limiting plate. A handle assembly is fixedly connected to the sliding push plate, and the handle assembly passes through the outer box and is slidably connected to the outer box.
[0009] As a further improvement of this utility model, a reset spring is fixedly connected between the sliding push plate and the limiting end plate.
[0010] As a further embodiment of this utility model: the handle assembly includes a guide rod and a grip, one end of the guide rod is fixedly connected to the sliding push plate, the other end of the guide rod is fixedly connected to the grip, and the guide rod is slidably connected to the outer box.
[0011] As a further improvement of this utility model, the distance between the limiting end plate and the side of the outer box away from the thrust component is a positive integer multiple of the width of the reagent kit box.
[0012] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure and is easy to use. When in use, by connecting the squeezing block to the reagent kit box, the required number of reagent kit boxes can be taken out by squeezing the block. This allows for better management of multiple sets of reagent kit boxes, avoiding the problems of loss and inconvenience caused by scattered placement of the reagent kit boxes after they are taken out. The utility model has good performance and is worth promoting. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] Example 1, please refer to Figure 1-4 A plasma separation and detection kit includes several kit housings 1 and an outer housing 2. The kit housings 1 are placed inside the outer housing 2. A guide limiting plate 3 is fixedly connected to the inner side of the outer housing 2. A squeezing block 4 is fixedly connected to the end of each kit housing 1. A guide notch 5 is formed between the kit housing 1 and the squeezing block 4. The guide notch 5 is slidably engaged with the guide limiting plate 3. The outer housing 2 has a placement hole 6 for inserting the squeezing block 4. A thrust assembly 7 for pushing the squeezing block 4 is also connected to the outer housing 2.
[0023] In use, this invention places several reagent kits 1 inside the outer casing 2. During use, a pushing force is applied by the pushing component 7, which moves the squeezing block 4. The squeezing block 4 pushes the reagent kits 1 inside the casing to move synchronously, causing the outermost reagent kit 1 to leak out of the outer casing 2. The squeezing block 4 at the end of the reagent kit 1 is then removed and inserted into the placement hole 6. The next time pressure is applied, the reagent kit 1 will be extruded. Initially, a squeezing block 4 needs to be placed inside the placement hole 6 to facilitate the extrusion of the first reagent kit 1. To prevent the squeezing block 4 from falling out of the placement hole 6, the outline size of the placement hole 6 can be slightly smaller than the outer size of the squeezing block 4. The squeezing block 4 is squeezed into the placement hole 6 under external force, thus preventing it from falling out. The return spring 11 can be omitted; instead, the position of the sliding push plate 9 can be adjusted manually by applying a pushing or pulling force.
[0024] Two sets of guide limiting plates 3 are symmetrically arranged inside the outer box 2. A limiting end plate 8 is fixedly connected between the two guide limiting plates 3. A placement hole 6 is opened between the guide limiting plate 3 and the outer box 2. The thrust assembly 7 has a sliding push plate 9, which is slidably connected to the guide limiting plate 3. A handle assembly 10 is fixedly connected to the sliding push plate 9, which passes through the outer box 2 and is slidably connected to it. A return spring 11 is fixedly connected between the sliding push plate 9 and the limiting end plate 8.
[0025] The thrust assembly 7 includes a sliding push plate 9 and a handle assembly 10. The handle assembly 10 applies a thrust, causing the sliding push plate 9 to slide along the guide limit plate 3 and simultaneously push the pressing block 4 to move. The reset spring 11 is provided so that the handle assembly 10 can automatically pop out under the action of the spring force without having to be manually pulled out. Of course, if cost is to be saved, the reset spring 11 can be omitted, and the position of the sliding push plate 9 can be adjusted by manually applying a push-pull force.
[0026] The handle assembly 10 includes a guide rod 12 and a grip 13. One end of the guide rod 12 is fixedly connected to the sliding push plate 9, and the other end of the guide rod 12 is fixedly connected to the grip 13. The guide rod 12 is slidably connected to the outer box 2.
[0027] Example 2: This example improves upon the previous example by setting the distance between the limiting end plate 8 and the side of the outer box 2 away from the pushing component 7 to a positive integer multiple of the width of the reagent kit box 1. This positive integer multiple size setting ensures that the outermost end face of the inserted reagent kit box 1 is flush with the outer box 2, allowing the reagent kit box 1 to be exposed under slight pressure, thus facilitating manual removal.
[0028] Working principle: In use, this utility model places several reagent kits 1 inside the outer box 2. During use, a pushing force is applied by the pushing component 7, which drives the squeezing block 4 to move. The squeezing block 4 pushes the several reagent kit boxes 1 placed inside the box to move synchronously, so that the reagent kit box 1 at the very end leaks out of the outer box 2. Then, the squeezing block 4 at the end of the reagent kit box 1 is removed and inserted into the placement hole 6. When pressure is applied again, the reagent kit box 1 can be squeezed out. In the initial state, a squeezing block 4 needs to be placed inside the placement hole 6 to facilitate the expulsion of the first reagent kit box 1. In order to prevent the squeezing block 4 from falling out of the placement hole 6 after being placed inside the placement hole 6, the outline size of the placement hole 6 can be slightly smaller than the outer size of the squeezing block 4. The squeezing block 4 is squeezed into the placement hole 6 under the action of external force, thereby preventing it from falling out. The thrust assembly 7 includes a sliding push plate 9 and a handle assembly 10. The handle assembly 10 applies a thrust, causing the sliding push plate 9 to slide along the guide limit plate 3 and simultaneously push the pressing block 4 to move. The reset spring 11 is provided so that the handle assembly 10 can automatically pop out under the action of the spring force without having to be manually pulled out. Of course, if cost is to be saved, the reset spring 11 can be omitted, and the position of the sliding push plate 9 can be adjusted by manually applying a push-pull force.
