Boosting device with dominant pressure adjustment and injection and sucking system

Abstract

The invention discloses a boosting device with dominant pressure adjustment and an injection and sucking system. The boosting device with dominant pressure adjustment is used for assisting an injectorto inject and suck autologous lipid on the basis of dominant pressure adjustment; the injector comprises a work drum, a needle head which is mounted on one side of the work drum, and a core rod whichis moveably embedded into the work drum; skit sides extending in a circumferential direction are arranged on sides, far away from the needle head, of the core rod and the work drum; and the boostingdevice with dominant pressure adjustment comprises a display setting unit and a booster in wireless communication connection with the display setting unit. The boosting device is capable of intelligently sucking lipid of a human body on the basis of pressure adjustment, and injury to the human body can be reduced in the liposuction process; and the lipid can be injected intelligently on the basisof pressure adjustment to implement a cosmetic surgery, the number and part of injected lipid can be adjusted according to pressure variation in the injection process, survival of the lipid in a bodycan be promoted, and the healing speed of wounds can be increased.

Description

technical field [0001] The application belongs to the technical field of biomedical engineering, and in particular relates to a booster device for pressure-led regulation and an injection and suction system. The device can intelligently suck fat based on pressure regulation and reduce the damage to the human body during the liposuction process; at the same time, it can intelligently inject fat based on pressure regulation for cosmetic surgery, which can be applied to treatments such as wrinkle removal, breast augmentation, and nose pad. During the injection process, the amount, location and mode of the injected fat can be adjusted according to the pressure change, which can promote the survival of the fat in the body and accelerate the healing of the wound. Background technique [0002] Treatment of autologous fat in vitro and reinfusion into the body for cosmetic operations such as wrinkle removal and breast augmentation has the advantages of less immune rejection, longer r...

AI Technical Summary

Problems solved by technology

However, there are following defects in actual clinical application: (1) when obtaining autologous fat, the current negative pressure liposuction equipment has certain damage to the human body, and the autologous fat taken out entrains more other connective tissues, which affects the cosmetic effect; 2) When using human autologous fat for cosmetic injection, at present, the injection is performed manually by pushing the needle manually with a syringe. The injection pressure is sensed and controlled by the human touch, and it is impossible to accurately understand the pressure at the injection site in real time. As a result, it is difficult to grasp the quantity, site and mode of injection, which affects the survival rate of the fat at the injection site, and causes problems such as necrosis of the transplanted fat.
