Introductions For Medical Beauty Nine Needle

The utility model relates to the technical field of medical instruments, in particular to a nine-hole injection needle for medical beauty,  which has the technical scheme key points that: the syringe comprises a syringe barrel, a piston seat, a base and a syringe needle, wherein the piston seat is accommodated in the syringe barrel, and one end of the piston seat extends outwards of the syringe barrel and is provided with a pressing part; the base is detachably connected to one end, far away from the pressing part, of the needle cylinder, nine accommodating cavities are formed in the base and communicated with the inner cavity of the needle cylinder; the needle head is inserted into the opening of the containing cavity. The utility model has the advantages of accurate injection, uniform injection, high safety and high efficiency.

At present, most of the common water-light injection needles are single needles, and high-end injection products such as hyaluronic acid, collagen, botulinum toxin, PRP autologous cells and the like which are lost due to aging of a human body are injected into the dermis layer of the skin by utilizing the negative pressure principle, so that sufficient water is absorbed and stored in the skin to wake up the cell regeneration function, the withered and broken cells of the skin are restored, and the firmness, smoothness and elasticity of the skin are reconstructed in a short period. The structure of single needle formula is comparatively conventional, during the injection, the needle contact skin can lead to the skin to sink the back just can pierce through the skin in the twinkling of an eye during single needle injection, and according to the difference in injection region, the degree of sinking is different, lead to unable accurate control injection depth, there is certain potential safety hazard, on the other hand, because what single needle syringe needle adopted is the punctiform injection, inefficiency, require higher to the operator, still can lead to the regional interior injection point of injection that needs to inject and distribute unevenly, injected liquid medicine can not be evenly absorbed by the skin, cause certain influence to final effect.

Therefore, a water light injector with accurate injection, uniform injection and high safety is needed.
