A kind of acne therapeutic equipment for dermatology
Technical field
The present invention relates to beautifying skin the field of medical instrument technology, specifically, refer to a kind of acne for dermatology
Therapeutic equipment.
Background technique
Acne can be described as acne vulgaris again, be that blackhead occurs for a long time for a kind of skin, (white or milky are broken for Whiteheads
The thorn-like papule of rice shape), whelk, skin bellding, again or stay the situation of scar;Most people have the experience of long acne, and are permitted
The mode of more people's processing is to squeeze affected part with finger, by acne or intrafollicular purulence blood by extruding in hair follicle, however, the hand of people
Refer to that often germ (nail slot is especially true) and skin surface can be there are many germs, if the case where not cleaning really with there are many
It is directly squeezed under even with finger and is very easy to cause to infect and cause chafing honeycomb tissue scorching.
Therefore, occur on the market it is many squeeze or pull out the utensils of acne instead of finger, such as one kind be commonly called as acne stick or
The utensil of youth stick mainly squeezes affected part with a ring, to generate average pressure around affected part, by acne or purulence blood
It is extruded by hair follicle, such utensil sometimes cannot squeeze out completely acne, and purulence shape object can retain for a long time, seriously in skin
Formation acne, even if oneself light detumescence, can also leave blackhead, if it is the people more than subcutaneous fat, due to powder in skin
Pierce it is small in size, it is red and swollen after skin be difficult to turn up the extruding to be formed to acne, in extrusion process, if failing to carry out skin
Disinfection in time, it is likely that even it is scorching to cause affected part inflammation honeycomb tissue occur.
