[0036] according to Figures 1 to 4 As shown, this utility model exemplifies a reagent storage base capable of storing reagent bottles of various sizes and a reagent kit using it. The reagent storage base includes a base body 10, on which multiple sets of placement slots 11 of different sizes are provided. Each placement slot 11 is filled with a detachable expansion component. In use, the expansion component of the corresponding size can be selected and removed according to the specific size of the reagent bottle 1, so that the placement slot 11 can hold the reagent bottle 1 of the corresponding size. Compared with the prior art, this application overcomes the problems of limited applicability, insufficient scalability, and waste in the prior art by using a modular standardized design for the placement slots 11 and the expansion components in the placement slots 11 can be disassembled and used in different ways, covering common test reagent bottle sizes.
[0037] In this embodiment, the base body 10 has several sets of placement slots 11 for placing reagent bottles of different sizes. The opening of the placement slot 11 is circular, and the diameter of the opening of each set of placement slots 11 is different. The bottom surface of the placement slot is sealed and a reset spring device is provided in the center.
[0038] Specifically, the base body 10 is a rectangular shape made of EVA foam.
[0039] Specifically, the inner wall of the placement groove 11 is provided with a wavy textured structure to increase the friction of its contact surface.
[0040] Specifically, a label plate 12 is provided on the open side of the placement slot for attaching labels.
[0041] Specifically, such as Figure 4As shown, the reset spring device includes a piston plate and a spring 113 connected sequentially from top to bottom. The piston plate is circular and can move up and down along the inner wall of the placement groove. Under the action of the spring 113, the piston plate can move slightly up and down along the placement groove 11. The spring is a slightly elastic spring that connects and supports the piston plate. The entire reset spring device is used to lift the reagent bottle, allowing a portion of the shorter reagent bottle to protrude after being placed in the placement groove, making it easier for personnel to remove. Furthermore, the piston plate can be formed by a support plate 111 and a fixing ring 112 being snapped together. The fixing ring 112 is embedded in the bottom of the support plate 111 to fix one end of the slightly elastic spring.
[0042] In this embodiment, the extension component is embedded in each set of placement slots 11. The extension component can be detachably filled with the space above the reset spring device in the placement slot. Each set of extension components includes a plunger 21 and at least one washer 22. The washer 22 is sleeved between the plunger 21 and the inner wall of the placement slot 11.
[0043] Specifically, the contact surfaces of the expansion component and the placement groove 11, as well as the inner wall of the placement groove 11, can be provided with a wavy textured structure to increase the friction between them. At the same time, the contact surface between the expansion component and the reagent bottle 1 can also be provided with a wavy textured structure, which can also increase the friction of the reagent bottle 1 in the placement cavity when the reagent bottle 1 is placed.
[0044] Specifically, a set of extension components may include a plunger 21 and a washer 22 fitted on the outer layer of the plunger 21, the washer 22 being a hollow cylinder.
[0045] Specifically, a set of extension components may also include a plunger 21 and two washers 22 of different sizes, with the two washers 22 being fitted onto the outer layer of the plunger 21 in ascending order of size, and both washers 22 being hollow cylinders.
[0046] Specifically, the base body 10 has 7 sets of placement slots 11 of different sizes, and each set of placement slots 11 is embedded with an extension component of different sizes. For example, a set of placement slots 11 is filled with a solid plunger 21 with a diameter of 4cm. The solid plunger 21 is covered with a hollow cylindrical washer 22 with an inner diameter of 4cm and an outer diameter of 4.5cm. The washer 22 is covered with another hollow cylindrical washer 22 with an inner diameter of 4.5cm and an outer diameter of 5cm. The second set of placement slots 11 is filled with a solid plunger 21 with a diameter of 3cm. The solid plunger 21 is covered with a hollow cylindrical washer 22 with an inner diameter of 3cm and an outer diameter of 3.5cm. The third set of placement slots 11 is filled with a solid plunger 21 with a diameter of 2.5cm. The fourth set of placement slots 11 is filled with a solid plunger 21 with a diameter of 0.5cm. ... By disassembling and assembling the plunger 21 and the washer 22, each set of placement slots 11 can hold reagent bottles 1 of different sizes to meet various needs.
[0047] Specifically, the diameter of the multiple placement slots 11 ranges from 0.5 to 5 cm. They can be freely combined and disassembled through the expansion components. The reagent storage base can be adapted to reagent bottles 1 with a diameter of 0.5-5 cm and a height of 10 cm or less, covering the specifications of common test reagent bottles 1.
[0048] Specifically, both the base body 10 and the expansion components are made of EVA foam, which facilitates quick assembly and disassembly of the expansion components.
[0049] The expansion component can be detachably filled into the placement slot 11. When placing the reagent bottle 1, the corresponding expansion component is detached according to the diameter of the placed reagent bottle 1.
[0050] Another aspect of this application discloses a reagent kit, including a kit body containing a reagent storage base as described above.
[0051] Specifically, a buffer layer with a thickness of 0.5cm is provided between the reagent storage base and the main body of the box.
[0052] Specifically, the box body is made of 400 single copper laminated with white reinforced pit material.
[0053] The principle of using the reagent kit in this application is as follows: Open the lid of the reagent kit, and according to the diameter of the reagent bottle 1 to be stored, remove the plunger 21 in the corresponding placement slot 11 or remove the plunger 21 and the gasket 22 together. Then, slowly insert the reagent bottle 1 into the empty placement slot 11 until the reagent bottle 1 contacts the reset spring device at the bottom of the reagent kit. Finally, close the lid of the reagent kit.
[0054] In summary, the technical solution of this application has the following beneficial effects:
[0055] 1. The reagent base of this application is designed with placement slots of different diameters, which can accommodate reagent bottles of different sizes, thus overcoming the problem of the placement slots in the prior art being able to accommodate only one type of reagent.
[0056] 2. Through the standardized design of the modular placement slot and the free combination of the expansion components, the applicability is flexible. The expansion components are made of EVA foam and the placement slot is filled with the expansion components. It can be quickly disassembled and assembled. By disassembling and assembling the expansion components, it can be adapted to reagent bottles with a diameter of 0.5-5cm and a height of 10cm, covering common test reagent bottle specifications, and overcoming the defect of the non-adjustable capacity of the placement slot in the existing technology.
[0057] 3. The reagent base and the reagent kit body of this application adopt a physical embedding method, which is convenient for installation. The reagent base and the reagent kit body can be reused, reducing procurement and storage costs. The modular multi-set placement slots of the reagent base reduce manufacturing and usage costs.
[0058] 4. An internal buffer layer is provided between the reagent base and the reagent kit body in this application to ensure stable transportation of the reagent bottle.
[0059] The above are merely exemplary embodiments of this application and are not intended to limit the scope of protection of this application, which is determined by the appended claims.
