Negative pressure drainage device for breast surgery

Abstract

The invention discloses a negative pressure drainage device for breast surgery. The device comprises a shell I and a shell II, both the left side and the right side of the shell I are provided with through holes and are fixedly connected to a one-way valve I and a one-way valve II respectively through the through holes, the inner wall of the shell I is slidably connected to a piston, the left sideof the shell II is provided with a through hole and is fixedly connected to the surface, close to the right side, of the one-way valve II through the through hole in a sealing way, and the upper surface of the shell II is fixedly connected to a double-shaft motor. According to the invention, the matching use of the structures solves the problems that: in the practical use process, traditional negative pressure devices can hardly provide a stable negative pressure environment for tissue fluid, once the tissue fluid drainage is too high, the drainage effect is poor, the drainage efficiency is reduced, the backflow phenomenon is easy to occur, secondary pollution is generated, solid substances in the tissue fluid are easy to block a drainage tube, medical accidents are easily caused if the drainage tube is not treated in time, and inconvenience is brought to the use.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a negative pressure drainage device used in breast surgery. Background technique [0002] Current research proves that negative pressure drainage therapy can accelerate the blood circulation of the wound, significantly promote the entry of new blood vessels into the wound, stimulate the growth of granulation tissue, fully drain, reduce edema, reduce pollution, inhibit bacterial growth, and directly accelerate wound healing, or Creating conditions for surgical repair is an efficient, simple, and economical pure physical therapy that promotes wound healing; however, in actual use, because traditional negative pressure devices are difficult to provide a stable negative pressure environment for interstitial fluid, once the interstitial fluid is drained excessively, The drainage effect will become poor, resulting in reduced efficiency, easy backflow, and secondary pollution;...

[0002] Current research proves that negative pressure drainage therapy can accelerate the blood circulation of the wound, significantly promote the entry of new blood vessels into the wound, stimulate the growth of granulation tissue, fully drain, reduce edema, reduce pollution, inhibit bacterial growth, and directly accelerate wound healing, or Creating conditions for surgical repair is an efficient, simple, and economical pure physical therapy that promotes wound healing; however, in actual use, because traditional negative pressure devices are difficult to provide a stable negative pressure environment for interstitial fluid, once the interstitial fluid is drained excessively, The drainage effect will become poor, resulting in reduced efficiency, easy backflow, and secondary pollution; moreover, the solid matter in the interstitial fluid will easily block the drainage tube. inconvenient
