Description

Cell culture device

Technical Field

The utility model relates to the technical field of cell culture, in particular to a cell culture device.

Background

Cell culture (cellcell) refers to a method for simulating in vivo environment (sterility, proper temperature, pH value, certain nutritional conditions, etc.) in vitro to make it survive, grow, reproduce and maintain the main structure and function. Cell culture is an essential process for both the whole bioengineering technique and one of the biological cloning techniques, and is itself a large-scale cloning of cells. Taking certain tissue cells from a body under a sterile environment (according to the purpose of an experiment), inoculating the tissue cells into a culture vessel after certain treatment (such as digestion, cell dispersion, separation and the like), inoculating tissue blocks into the bottom of the culture vessel, sticking the tissue blocks onto the bottom after several hours, adding a culture medium, and immediately putting the cells into an incubator after the cells enter the culture vessel so as to enable the cells to enter a growth state as early as possible. The cells being cultured should be observed at regular intervals, including whether the cells are growing well, whether the morphology is normal, whether there is contamination, whether the pH of the medium is too acidic or too basic (indicated by phenol red indicator), and also the culture temperature and CO2 concentration should be checked at regular intervals. The usage rate of the culture dish in the cell culture experiment is higher than that of the culture bottle, and the culture dish is more convenient for the blowing operation of the cells and the cell collection is more thorough. The culture dish consists of a flat disc-shaped bottom and a lid.

When the cells are cultured, the cells absorb and generate gas so as to change the gas and liquid environment in the culture dish. In the prior art, a gap exists between a culture body and a culture dish cover, so that gas exchange during cell culture is facilitated, but the gap is large, and fungi in the air easily enter a culture dish to cause cell pollution; liquid is easy to leak from the gap by shaking in the moving process of the culture dish, and pollution is also caused. In addition, the culture body and the culture dish cover of the culture dish are separated, so that the culture dish cover is easy to open to cause cell pollution when the culture dish is moved; when a plurality of culture dishes are operated, the culture dish cover is easy to cover by mistake, and cell pollution can be caused. There is therefore a need for further improvements in cell culture dishes to address the problems described above.

SUMMERY OF THE UTILITY MODEL

The present invention provides a cell culture apparatus that solves the problems set forth in the background art described above.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a cell culture device, includes the culture dish body, the top of culture dish body is equipped with the top cap, fixedly connected with connecting piece between the one end of top cap and the outside one end of culture body, and ventilative mouthful has been seted up at the top of top cap, fixedly connected with filtration membrane in the ventilative mouthful.

As a preferable technical scheme of the utility model, a first magnetic sheet is embedded on the outer side of the culture dish body, and a second magnetic sheet corresponding to the first magnetic sheet is embedded on the inner side wall of the top cover.

As a preferable technical scheme of the utility model, the handle is fixedly connected to the outside of the top cover.

As a preferred technical scheme of the utility model, the top end of the culture dish body is fixedly connected with a silica gel pad.

As a preferred technical scheme of the utility model, the connecting piece is made of silica gel.

The utility model has the following advantages: according to the utility model, the culture dish body and the top cover are respectively provided with the first magnetic sheet and the second magnetic sheet, so that the culture dish body and the top cover can be tightly connected, and the air-permeable port and the air filtering membrane are arranged, so that dust, water vapor, bacteria and viruses in the air can be isolated, a good culture environment can be maintained, and cells in the culture dish can be effectively prevented from being infected.

Drawings

FIG. 1 is a schematic view of the structure of a cell culture apparatus.

FIG. 2 is a cross-sectional view of a top cover in the cell culture apparatus.

In the figure: 1. a culture dish body; 2. a top cover; 3. a connecting member; 4. a ventilation opening; 5. a handle; 6. a first magnetic sheet; 7. a second magnetic sheet; 8. an air filtration membrane; 9. a silica gel pad.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
