Description

Technical Field

[0001] The utility model relates to the technical field of hair follicle repair devices, in particular to a stem cell exosome hair follicle repair liquid administration device. Background Art

[0002] Stem cell exosomes refer to a type of extracellular vesicles released by stem cells, which contain a variety of bioactive substances, such as proteins, nucleic acids, lipids and cytokines. These substances can transmit information and regulate signals between cells through the release and transmission of exosomes, and have important biological functions and potential clinical application value. Stem cell exosomes are extracellular vesicles released by stem cells and can be prepared by culturing and collecting exosomes in stem cell cultures. Common stem cell sources include mesenchymal stem cells, placental stem cells and umbilical cord blood stem cells. Stem cell exosomes contain rich bioactive substances, such as proteins, nucleic acids, lipids and cytokines. The bioactive substances in stem cell exosomes, such as cytokines and growth factors, have the ability to promote cell proliferation and differentiation. These substances can promote the regeneration and development of hair follicles by interacting with hair follicle cells. Inflammation is one of the common causes of hair follicle degeneration and hair damage. Studies have shown that some components in stem cell exosomes can inhibit inflammatory responses, reduce the infiltration of inflammatory cells and the release of inflammatory mediators, thereby protecting and repairing damaged hair follicles. When using hair follicles, a drug delivery device is required for operation.

[0003] Most of the stem cell exosome hair follicle repair solution delivery devices currently on the market have the following problems when used:

[0004] When the traditional stem cell exosome hair follicle repair liquid dosing device is actually used, the drug delivery device presses the medicine directly on the surface of the hair follicle. The pressed medicine is in the form of water droplets. When the user shakes it, the medicine will slip, making it difficult to stably apply the medicine to the position that needs repair. When the traditional stem cell exosome hair follicle repair liquid dosing device is actually used, the medicine will be uniformly loaded into the inside of the drug delivery device, and it is difficult to control the pressing force according to the dosage value. If the force is too large or too small, it will cause more or less medicine to flow out, which is very inconvenient when administering. Utility Model Content

[0005] 1. Technical issues to be solved
