Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a negative pressure drainage device for assisting drainage during liposuction. Background Art

[0002] With the development of the medical beauty industry, more and more obese people choose liposuction to extract fat in order to achieve the purpose of weight loss. Liposuction is fat suction, also known as liposuction weight loss and body sculpting. It uses an instrument to reach into the subcutaneous fat layer through a small incision in the skin to extract fat fragments to achieve the purpose of absorbing fat. It is suitable for body plastic surgery, and the negative pressure drain is a commonly used medical device in liposuction. The negative pressure drain is used to connect to the drainage tube implanted in the patient's body to drain the patient's fat after the operation to the outside of the body, thereby achieving weight loss.

[0003] Patent CN216257228U discloses a negative pressure drainage device for assisting drainage during liposuction, which includes a negative pressure drainage bottle, a drainage tube A and a drainage tube B. The port of the negative pressure drainage bottle is fixedly connected with a bottle mouth sleeve, and the negative pressure drainage bottle is connected to the drainage tube A through the bottle mouth sleeve. The end of the drainage tube A is connected to a pipe sleeve that can play a non-return effect, and the end of the pipe sleeve is connected to the drainage tube B. The outer surface of the drainage tube B is fixedly sleeved with a collar. During liposuction, the device can evenly suck the surrounding fat because the suction end is in a flat rectangular setting and the port range of the diversion cavity is in a rectangular shape, which can effectively ensure the flatness of the surrounding fat. The baffle strip, the diverter strip A and the diverter strip B have a certain diversion effect, so that the fat can be evenly introduced into the suction end, which can effectively prevent the suction end from being blocked.

[0004] Patent CN210990618U discloses a negative pressure drainer for assisting drainage during liposuction, which includes a first needle tube, a second needle tube, a first drainage tube and a second drainage tube.
