Description

Interlayer cup saucer without residual liquid

Technical Field

The utility model belongs to medical science inspection equipment field specifically is a no raffinate intermediate layer cup saucer.

Background

The filtering type sandwich cup is a patent product, and can be operated by adopting various reagents in the using process, for example, more than 5 different reagents can be adopted in the acid-resistant dyeing process, the requirement on a device for bearing the sandwich cup is very high, the first reagent ensures that residual liquid is as little as possible after negative pressure suction is finished, otherwise, the effect of the next reagent is influenced, and the dyeing result is seriously influenced.

The residual liquid often occurs at the gap where the filter membrane sticking position of the filter sandwich cup body is contacted with the filter screen plate, and the gap cannot be avoided due to the design of the sandwich cup structure, so that the residual liquid is difficult to remove.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the utility model provides a there is not raffinate intermediate layer cup saucer, its main advantage lies in can will filtering formula intermediate layer bottom of cup filter membrane position and remain liquid and fall to minimum.

In order to realize the above purpose, the utility model adopts the technical scheme that: a sandwich cup saucer without residual liquid comprises a supporting barrel, wherein a communicated negative pressure pipe is arranged on the bottom surface or the side wall of the bottom of the supporting barrel; the inside of the supporting barrel is provided with a screen plate which divides the supporting barrel into a placing cavity at the upper end for placing the filtering type interlayer cup and a negative pressure cavity at the lower end; the periphery of the outer diameter of the screen plate is provided with a bulge along the radial direction.

A circle of bosses are arranged on the inner wall of the lower end of the supporting barrel; the screen plate is arranged on the boss.

The edge of the mesh plate is in a gear shape.

The net plate consists of a supporting net and an edge wrapping ring.

The supporting net is a steel wire mesh; the edge wrapping ring is made of plastic materials.

Barrel ears are arranged on two sides of the upper end of the support barrel.

The utility model has the advantages that:

the gear-shaped mesh plate can be composed of a steel wire mesh and a covered plastic ring, the periphery of the covered plastic ring is in a gear shape, so that a gap between the pasting position of the filter membrane of the filtering type interlayer cup body and the filter mesh plate is ensured to be in an open state, and residual liquid can be completely taken away under the action of negative pressure. The steel wire mesh is 80-100 meshes, so that not only is certain strength maintained, but also microscopic observation is not influenced by traces on the filter membrane.

Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

As shown in fig. 1-3, the structure of a specific embodiment of the present invention: a sandwich cup saucer without residual liquid comprises a supporting barrel 1, wherein a communicated negative pressure pipe 4 is arranged on the bottom surface or the side wall of the bottom of the supporting barrel 1; the inside of the supporting barrel 1 is provided with a screen plate 6 which divides the supporting barrel 1 into a placing cavity 5 at the upper end for placing the filtering type interlayer cup and a negative pressure cavity 3 at the lower end; the periphery of the outer diameter of the screen plate 6 is provided with a bulge along the radial direction.

As shown in fig. 1, as a preferred embodiment of the present invention, a circle of bosses 2 is provided on the inner wall of the lower end of the supporting barrel 1; the screen plate 6 is arranged on the boss 2.

As shown in fig. 2, in order to minimize the residual liquid at the bottom of the filtering interlayer, the edge of the mesh plate 6 is in the shape of a gear as a preferred embodiment of the present invention.

As shown in fig. 2, as a preferred embodiment of the present invention, the mesh plate 6 is composed of a supporting mesh 61 and a binding ring 62; the periphery of the edge covering ring 62 is in a gear shape. The teeth of the gear are arc bulges.

As a preferred embodiment of the present invention, in order to lift the filter membrane 8, the supporting net 61 is a steel wire mesh; the edge covering ring 62 is made of plastic.

As shown in fig. 3, in order to facilitate taking out the filtering type sandwich cup, as a preferred embodiment of the present invention, two sides of the upper end of the supporting barrel 1 are provided with barrel ears 9.

The design principle of the utility model is as follows:

1. the bottom of the filtering type interlayer cup 7 is provided with a filtering membrane 8; a cup holder with sandwich layer without residual liquid is composed of a supporting barrel and a screen plate with a boss on its external circumference.

2. The cup support barrel comprises an inner cavity, two cup taking lugs, a negative pressure nozzle and a screen plate platform, wherein the inner cavity comprises a negative pressure cavity and an object placing cavity, the radius difference between the object placing cavity and the negative pressure cavity is the size of the screen plate platform, and the size of the screen plate platform is smaller than the size of the bulge. Injection molded from a flexible material. The material can be silica gel or rubber, and is sealed with the filtering interlayer cup body to facilitate the negative pressure suction of liquid.
