Description

Handheld bacteriophage micro-acupuncture injector

Technical Field

The utility model relates to a medicine and chemical industry field, especially a hand-held type phage micro-acupuncture syringe.

Background

The bacteriophage is a bacterial virus, can be self-replicated in cells by virtue of a replication system of a host after infecting bacterial cells, and finally releases progeny bacteriophage in a manner of breaking the host. In the medical field, the bacteriophage with the capability of cracking bacteria can be used as a bactericidal preparation to be applied to in-vivo and in-vitro bactericidal treatment, and particularly, some stubborn bacteria with antibiotic resistance are more suitable for the application of bacteriophage bactericides.

When phage bactericides are used for some skin surface infections, topical application is usually carried out by means of smearing and application. Because the bacteriophage has a virus structure and the size of the bacteriophage is usually larger than 100nm, the bacteriophage can not be directly absorbed and entered by epithelial tissues like chemical micromolecule drugs, the contact area of focuses and the killing probability are greatly reduced, and the exertion of the drug effect is seriously influenced. When large-area skin tissue damage infection such as burn and large-area open wound occurs, the focus tissue can be cut through surgical operation, and the wound surface is repeatedly cleaned by using phage bactericidal liquid. However, for some small bacterial tissue infections, such as acne and the like, more elaborate subcutaneous administration is required. Traditionally, the local injection of the infected part is still performed by adopting a common injector, and the mode is time-consuming, labor-consuming and low in working efficiency. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
