Description

Stem cell injection anti-pollution device

Technical Field

The utility model relates to the technical field of stem cell injection, in particular to an anti-pollution device for stem cell injection.

Background

In the field of biological experiments, if research and observation of stem cells are required, the stem cells need to be injected into a culture dish through a syringe for research.

However, if it is desired to inject the stem cells into the culture dish, it is necessary to open the culture dish and then inject the stem cells into the culture dish using a syringe. But this operation causes the stem cells to come into contact with air, thereby easily contaminating the stem cells.

Therefore, there is an urgent need in the market for a stem cell injection contamination prevention device for solving the above-mentioned problems.

Disclosure of Invention

The utility model aims to provide an anti-pollution device for stem cell injection, which is used for solving the technical problems in the prior art, and stem cells in an injector can be directly injected into a culture dish to avoid the contact of the stem cells with air, thereby preventing the stem cells from being polluted.

In order to achieve the above object, the present utility model provides the following solutions:

the utility model discloses an anti-pollution device for stem cell injection, which comprises:

the culture dish is provided with an injection channel on the side wall, the injection channel is positioned in the culture dish, and one end of the injection channel is provided with a sterile diaphragm;

the syringe, the syringe needle outside is equipped with aseptic gum cover, the syringe needle can stretch into in the injection passage, the syringe needle can be impaled simultaneously aseptic gum cover with aseptic diaphragm.

Preferably, the sterile rubber sleeve and the sterile diaphragm are made of rubber.

Preferably, the culture dish comprises an upper cover and a bottom bracket, and the upper cover and the bottom bracket can be detachably connected;

one end of the injection channel is fixed on the side wall of the bottom bracket.

Compared with the prior art, the utility model has the following technical effects:

according to the utility model, the needle head of the syringe extends into the injection channel, and the sterile rubber sleeve and the sterile diaphragm are sequentially pierced, so that the end part of the needle head of the syringe is positioned in the culture dish, and then the syringe is pushed, so that stem cells can be completely injected into the culture dish. Since the culture dish is not opened during the whole process, the stem cells are not contacted with air, so that the stem cells are not polluted.

Drawings

In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the drawings that are needed in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present utility model, and other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.

FIG. 1 is a schematic diagram of a stem cell injection contamination prevention device according to an embodiment of the present utility model;

in the figure: 1-a culture dish; 101-an upper cover; 102-a shoe; 103-an injection channel; 104-a sterile septum; 2-a syringe; 201-sterile rubber sleeve; 100-stem cell injection anti-pollution device.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.

As shown in fig. 1, the present embodiment provides a stem cell injection contamination prevention device 100, including:

the culture dish 1, the sidewall of the culture dish 1 is provided with an injection channel 103, the injection channel 103 is positioned in the culture dish 1, and one end of the injection channel 103 positioned in the culture dish 1 is provided with a sterile diaphragm 104;

the syringe 2, the syringe 2's syringe needle outside is equipped with aseptic gum cover 201, and syringe 2's syringe needle can stretch into in the injection passageway 103, and syringe 2's syringe needle can pierce aseptic gum cover 201 and aseptic diaphragm 104 simultaneously.

In practical use, if stem cells need to be injected into the culture dish 1, the needle of the syringe 2 needs to be inserted into the injection channel 103, and the sterile rubber sleeve 201 and the sterile membrane 104 are sequentially pierced, so that the end of the needle of the syringe 2 is positioned in the culture dish 1, and then the stem cells can be completely injected into the culture dish 1 by pushing the syringe 2.
