Description
Technical field
The invention belongs to medical instruments fields, and in particular to a kind of blood vessel alarm injection needle.
Background technique
With advancing age, wrinkle is increasing as a kind of skin ageing phenomenon, from viewpoints such as beauty, especially
For women, to wrinkle prevent and improved interest significantly improves.Wrinkle is according to its happening part, mechanism etc.
It is different and be substantially divided into big wrinkle, small wrinkle, gauffer wrinkle.Big wrinkle is mainly due to light aging and in forehead, nape etc.
Locate the deep wrinkle generated, small wrinkle is the wrinkle shallower in the ratio of the eye tip, corners of the mouth generation, and gauffer wrinkle is the abdomen etc. in old man
The pleated wrinkle that non-exposed position generates.Liking to be beautiful is the nature of people, and under the trend for pursuing beauty, more and more people start beauty
Hold glossiness, sophistication etc. that medical institutions carry out aesthetic nursing or micro-shaping to improve skin, beauty mechanism passes through in wrinkle
Position injection hyaluronic acid, botulin toxin etc. achieve the purpose that beauty smoothing wrinkle, but one during injecting these substances
Denier misoperation has punctured biggish blood vessel, by filler injected into blood vessel, is easy to cause blood vessel embolism, thus can be to human body
It causes serious injury, can operator has found that can bleeding take appropriate measures in time, be the pass that prevent embolism to occur in time
Where key.
Existing injection device, such as Chinese patent literature data disclose the one of Patent No. CN201720671719.7
Kind cosmetically anti-plug injection device, including injection needle tube and injection needle, the front end of the injection needle tube is equipped with nipple, described
