Injection device for hair follicle stem cell culture and application method of injection device

Abstract

The invention discloses an injection device for hair follicle stem cell culture and an application method of the injection device. The injection device for hair follicle stem cell culture used by themethod comprises storage structures, a first driving structure, a housing, a fixing structure, a storing structure, a second driving structure, a falling structure and a pressurizing structure. According to the injection device disclosed by the invention, the condition that the first driving structure is propped to be conveniently driven, is facilitated, so that the two storage structures are driven by the first driving structure to automatically open and close; the second driving structure for sealing the storing structure is arranged on the storing structure; the pressurizing structure for pressurizing digestive medicines is arranged in the storing structure; and the second driving structure is connected to the pressurizing structure, so that the condition that when the injection deviceis not used, the storing structure is sealed by the second driving structure, is facilitated; and when liquid medicines need to be used, the pressurizing structure is driven by the second driving structure for pressurizing to drive the liquid medicines in the storing structure to be drained, the using of the liquid medicines is more convenient and flexible, and besides, the pollution of the liquidmedicines is avoided.

Description

technical field [0001] The invention relates to a culture device, in particular to an injection device for culturing hair follicle stem cells and a use method thereof, and belongs to the technical field of induction and differentiation of hair follicle stem cells. Background technique [0002] Hair follicle stem cells are a kind of hair follicle stem cells in the bulge of the outer root sheath of human hair follicles. Hair follicle stem cells are adult stem cells, which are in a quiescent state in vivo, and show amazing proliferation ability under in vitro culture. Studies have found that hair follicle stem cells have multidirectional Differentiation potential, it can differentiate into epidermis, hair follicles, sebaceous glands, and participate in the process of skin wound healing. During the culture process, it is necessary to use isolate enzyme to digest the isolated hair follicles, and use trypsin to digest the obtained hair follicle bulge. Different conversion directio...

Problems solved by technology

[0003] However, when using the injection device to absorb the digestive medicine inside the storage bottle, it is necessary to open and close the storage bottle frequently, the operation is cumbersome, and it is easy to cause the medicine inside the storage bottle to be polluted. When the amount of medicine to be used is large, Multiple aspirations are required, and it is inconvenient to open the storage box for the storage bottle and the straw of the injection device when the operator holds the culture dish in one hand and the injection device in the other hand
