technical field

The utility model relates to a cell culture appliance, which belongs to the field of biological medical appliances.

Background technique

In medical testing or biochemical laboratories, cells or tissues need to be cultured, and culture utensils are needed. A petri dish is a laboratory vessel used for cell or tissue culture, consisting of a flat disc-shaped bottom and a cover. , generally made of glass or plastic. Cell culture dishes are fragile and fragile, so they should be handled with care and care when cleaning and handling. The cell culture dish in the prior art is inconvenient to take and place and open and close the cover, and it is also inconvenient to use and clean. The invention patent with the patent number CN103320324A discloses a cell culture dish. A dish body flange is arranged on the side wall of the dish body. cleaning. However, after the petri dish is cleaned, in order to reduce the area of the place where it is placed, the bottom of the dish and the lid of the dish are stacked, but because of the water, it is easy to stick together when stacked, and it is not easy to dry.

Utility model content

In order to solve the above-mentioned technical problems, the object of the present invention is to provide a cell culture dish, which is not only convenient to take and place, open and close the cover and clean, but also easier to dry after cleaning, and can also timely remove the water evaporated from the culture medium. Drainage and diversion prevent water from falling on the cultured tissue cells, ensuring the quality of culture and reducing the probability of contamination.

In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a cell culture tool, comprising a dish bottom and a dish cover used in conjunction with the dish bottom, the dish cover includes a cover body and a The cover rim extends downward in the circumferential direction, the cover body includes a central central part and an inclined part between the central part and the cover rim, the central part is provided with a ventilating area with a ventilating port, the The air vent is provided with a filter membrane, and through the setting of the air vent, water vapor can be discharged without accumulating to form water droplets, and will not drip into the cultured cells, ensuring the quality of cell culture.

During the use of the petri dish, especially during the use of tissue culture, due to the moisture in the culture medium and the long cultivation time, under the action of temperature, the inside of the dish lid often has moisture that evaporates from the culture medium , the water is divided into beads, which will drip into the cultured tissue, affecting the culture of tissue cells and increasing the probability of contamination. In this solution, on the one hand, by setting an inclined part on the cover body, after the water is divided into beads, it can flow to the contact gap between the dish cover and the dish bottom along the inclined part; on the other hand, by setting a ventilation area, part of the water vapor passes through the ventilation holes Discharge, will not drip into the cultured cells, to ensure the quality of cell culture and reduce the probability of contamination.

Preferably, an installation groove with a notch facing the air outlet is provided around the edge of the air outlet, and the upper groove wall of the installation groove exceeds the lower groove wall of the installation groove, thereby reducing the probability of contamination.

Preferably, the diameter of the filter membrane is larger than that of the air vent to reduce the probability of contamination.

Preferably, the bottom of the dish includes a bottom and a bottom rim surrounding the bottom of the dish, the lower surface of the bottom of the bottom of the dish is provided with a support, and the support is arranged on the bottom of the bottom of the dish The support ring on the lower surface.

In the above technical solution, by setting a support member on the lower surface of the dish bottom, after cleaning the culture dish, the dish bottom and the dish cover are stacked, which occupies less space. Sticks well and dries more easily.

Preferably, the end of the bottom edge portion is provided with a flow guide portion inclined toward the dish cavity, so that the moisture can flow out along the flow guide portion more easily.

Preferably, the inclination angle of the guide part is 30-50°.

Preferably, side supports are provided on the outer surface of the bottom edge.

Preferably, the side support is a support block oppositely arranged on the outer surface of the bottom edge.

By implementing the above scheme, the utility model has the following beneficial effects: the utility model is not only convenient to take and place, open and close the cover and clean, but also easier to dry after cleaning, and can also discharge and guide the evaporated water in the culture medium, so that the water Do not fall on the cultured tissue cells to ensure the quality of the culture and reduce the probability of contamination.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Example 1:

A kind of cell culture dish as shown in accompanying drawing 1, comprises dish bottom 1 and the dish cover 2 that cooperates with described dish bottom 1, and described dish cover 2 comprises lid body 21 and by described lid body 21 along the circumferential direction The cover edge 22 extending downwards, the cover body 21 includes a middle horizontal central portion 211 and an arc-shaped inclined portion 212 located between the central portion 211 and the cover edge 22 , moisture will flow along the inclined portion 212 It flows to the edge 22 of the cover, and flows out through the gap between the edge 22 of the cover and the bottom 1 of the dish. The dish bottom 1 includes a bottom 11 and a bottom rim 12 surrounding a dish cavity 13 with the bottom 11. The lower surface of the bottom of the dish bottom 1 is provided with a support 101, which is a support arranged on the lower surface of the bottom of the dish bottom 1. lock up. Cooperating with the inclined part 212, the end of the bottom edge part 12 is provided with a guide part 121 inclined to the dish cavity 13, and the water flows out along the guide part 121. The preferred inclination angle of the guide part 121 is 30-50°. The present embodiment is 45°.

In addition, in order to reduce the accumulation of water vapor into water droplets, the central part 211 is provided with a ventilating area 2111 with a ventilating port, and the venting port is provided with a filter membrane 2112 to prevent external pollution sources from entering. The edge of the air vent is provided with a notch towards the installation groove 2113 of the air vent, the upper groove wall of the installation groove 2113 exceeds the lower groove wall of the installation groove, and the filter membrane is installed from the reverse side of the dish cover 2, preventing The pollution effect is better, and the diameter of the filter membrane 2112 is larger than that of the air vent.
