Description

Technical Field

[0001] The utility model belongs to the field of aseptic devices, and in particular relates to an aseptic device for preparing stem cells. Background Art

[0002] Sterile devices are usually used in fields such as medical, laboratory or food industry to maintain a sterile environment and prevent microbial contamination. These devices can be sterile workbenches, sterile rooms, incubators and other equipment. They eliminate microorganisms in the air by filtering the air or using ultraviolet rays to ensure the cleanliness of the working environment.

[0003] When culturing stem cells, the existing sterile incubator has an access structure that often uses a limited pulling method to access the culture dish containing stem cells. Therefore, it is very easy for the carrier plate to fall out of the incubator due to excessive pulling during use, thereby damaging the cultured stem cells or causing secondary infection. When accessing the culture dish, it is often necessary to pull it manually, and the temperature in the incubator will be adjusted according to the needs of stem cell culture, which may cause damage to the user's palm.

[0004] Therefore, in order to address the problem that when the above-mentioned sterile device is used to culture stem cells, it is very inconvenient to access the culture dish containing stem cells due to its imperfect access structure, a sterile device for stem cell preparation is developed. By adding an electric telescopic structure, a limit-limiting anti-drop structure and a double parallel outward movement structure to the sterile device, the convenience of users in accessing the culture dish can be greatly improved, the stability of the device can be improved, and the safety of the device when in use can also be improved.
