Description

Living tissue storage device

Technical Field

The invention relates to the technical field of living tissue preservation containers, in particular to a living tissue preservation device.

Background

The biopsy is the most important part of the diagnosis of pathology as the final clinical diagnosis, and a clear histopathological diagnosis can be made for the vast majority of the examined cases. In practice, after the biopsy tissue is separated from the human body, the collected specimen needs to be immersed in a preservation solution (such as formalin, etc.) for preservation, and then transferred to a laboratory or a pathology room for observation and study.

In the prior art, in order to avoid pollution, the living tissue is generally filled into a specimen bag, then a proper amount of preservation solution is poured into the specimen bag, and finally the bag opening is sealed. Although this storage method is simple and convenient, it has been found in practice that when a living tissue is stored in a specimen bag, the storage solution is likely to overflow and cause an irritating odor, and that the specimen bag is not fixed in shape and therefore needs to be filled with a large amount of storage solution, which results in waste of the storage solution.

In Chinese patent publication numbers: in the patent CN217446390U, a novel living tissue preservation cup is also provided, which comprises a cup body, a cup cover and a handle arranged at the top of the cup cover, wherein a connecting rod is arranged at the center of the lower surface of the cup cover, and the top end of the connecting rod is connected with the cup cover; the bottom of the connecting rod is provided with a pressing net which is in clearance fit with the inner surface of the cup body so that the pressing net can be taken out or put into the cup body, and the pressing net is provided with meshes. The method can ensure that the living tissues are soaked in 10% formalin solution, and avoid the tissue self-melting or putrefaction caused by the fact that the tissues are attached to the cup wall or the cup cover in the conveying process, which leads to histopathology detection failure.

Although the above-mentioned preservation cup can effectively infiltrate the living tissue into the formalin solution through the arrangement of the pressing net, we find that in the practical application, there are still some disadvantages, such as:

on one hand, a large amount of preservation solution still needs to be poured into the preservation cup, otherwise, when the cup body inclines, the preservation solution can not effectively cover the living tissues, and on the other hand, the preservation solution in the preservation cup still needs to be added manually, so that the problems of easy splashing, troublesome operation and the like exist.

Based on this, we propose a living tissue preservation device.
