Description

Technical Field

[0001] The utility model belongs to the field of biochemical experiment instruments, in particular to an ELISA plate dehydration device. Background Art

[0002] When conducting an ELISA experiment, after washing the ELISA plate, it is necessary to remove the water droplets on the ELISA plate. Currently, most people do this by placing the plate upside down on absorbent paper to absorb water, or by spinning it dry. If absorbent paper is used to absorb water, it is easy to cause sample contamination in the holes. If spinning is used for dehydration, the spun water droplets may contaminate other experimental materials. Although the document number is CN208007650U "An ELISA Experiment Clapping Box", which places the ELISA plate in a box and claps it so that the water droplets on the ELISA plate splash out and are absorbed by the absorbent paper for dehydration, there is still a possibility of contamination.

The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0031] Example 1

[0032] like Figure 1As shown, this embodiment provides an ELISA plate dehydration device, including a base box 1, a clamping plate 2 and a plurality of elastic members 3. The base box 1 is horizontally arranged with its box opening facing upward, the clamping plate 2 is horizontally arranged above the middle of the base box 1, and the plurality of elastic members 3 are vertically arranged at the edge of the lower end of the clamping plate 2 and are circumferentially spaced at the lower end of the clamping plate 2, and the lower end of each of the elastic members 3 is connected to the inner bottom wall of the base box 1, and the lower end of the clamping plate 2 is used to detachably clamp the ELISA plate 7, so that the ELISA plate can be inverted at the lower end of the clamping plate and clamped by the clamping plate, and then the clamping plate is pulled upward to make the elastic member in a stretched state, and then the clamping plate is instantly released, so that the clamping plate jumps up and down under the action of the plurality of elastic members to splash the water droplets on the clamping plate to be collected by the base box.

[0033] like Figure 1 and Figure 2 As shown, in the above technical solution, a "T"-shaped slot 21 is recessed at the lower end of the clamping plate 2, and one end of the slot 21 passes through the corresponding side of the clamping plate 2. The slot 21 is used for the ELISA plate 7 to be inserted upside down. It has a simple structure and makes it convenient to clamp the ELISA plate at the lower end of the clamping plate.

[0034] See Figure 2 As shown, the two sides of the lower end of the card slot 21 in the above technical solution are expanded in an "eight" shape, so that when the water droplets on the ELISA plate splash downward, they will not collide with the clamping plate and rebound.

[0035] like Figure 3 and Figure 4 As shown, in the above technical scheme, the lower end of the clamping plate 2 is located on both sides of the card slot 21 and is provided with multiple elastic members 3, and the multiple elastic members 3 on the same side are spaced apart along the length direction of the card slot 21, and its structure is simple, so the setting of the elastic members does not affect the plugging and unplugging of the ELISA plate, wherein it also includes multiple guide rods 4, multiple guide rods 4 are vertically arranged and pass through the edge of the clamping plate 2, and the lower ends of the guide rods 4 are connected to the inner bottom wall of the bottom box 1, and the clamping plate 2 can slide up and down relative to the multiple guide rods 4, so that the clamping plate can only move up and down under the action of the guide rods, which can improve its stability of up and down movement. Specifically, four guide rods 4 are provided, and one guide rod 4 is provided at each of the four corners of the clamping plate 2, so that the stability of the guide rods when sliding up and down is good.

[0036] See Figure 1As shown, in the above technical solution, an enlarged portion 41 is provided on the guide rod 4 below the clamping plate 2, and the horizontal heights of the plurality of enlarged portions 41 are consistent to limit the downward movement of the clamping plate 2, so that the clamping plate moves downward until it hits the enlarged portion, thereby making the water droplets on the ELISA plate splash out more effectively.

[0037] In this embodiment, the upper end of the guide rod extends out of the bottom box, and the enlarged portion 41 is located inside the bottom box.

[0038] In this embodiment, the elastic member may be a spring, and when no force is applied to the clamping plate, the clamping plate is located above the base box under the support of the elastic member, so that the end of the slot can be exposed outside the base box, thereby facilitating the insertion of the ELISA plate into the slot.

[0039] When the ELISA plate is dehydrated, a moisture-absorbing cotton towel can be placed on the inner bottom wall of the bottom box in advance, so that the moisture-absorbing cotton towel can absorb the water droplets splashed from the ELISA plate in time.

[0040] When the ELISA plate in this embodiment is inserted into the slot, the sample wells in the middle of the ELISA plate are all located in the open area at the lower end of the slot (only the edges of the ELISA plate are inserted into the slot).

[0041] Example 2

[0042] like Figure 5 As shown, the embodiment 1 is different in that the embodiment further includes a handle bar 5 vertically arranged in the middle of the upper end of the clamping plate 2, so that the handle bar can be used as a handle to drive the clamping plate to overcome the elastic force of the elastic member to move upward.

[0043] The above technical solution also includes a top box 6, the box opening of the top box 6 faces downward, and the box opening of the top box 6 is detachably connected to the box opening of the bottom box 1. A hole 61 is provided in the middle of the upper end of the top box 6 for the handle rod 5 to pass through, so that the ELISA plate can be dehydrated in the box chamber formed by the top box and the bottom box during dehydration, which can prevent water droplets from splashing.

[0044] In the above technical solution, the upper end of the guide rod 4 protrudes out of the bottom box 1, and when the top box 6 is docked with the bottom box 1, the upper end of the guide rod 4 is close to the inner top wall of the top box 6, so that the top box can limit the upward movement of the clamping plate.

[0045] In this embodiment, the top box can be moved upward along the handle rod until it is separated from the handle rod, and the box opening of the top box is a stepped box opening, which can be docked with the box opening of the bottom box and clamped, so that the bottom box and the top box have a certain bite force when docked (not easily loosened).
