Abstract

The invention discloses a negative-pressure drainage device, which comprises a drainage tube, a negative-pressure device, a connecting tube and a drainage bag, wherein the front end of the drainage tube is provided with a side hole, and the back end of the drainage tube is connected with the negative-pressure device; the negative-pressure device comprises a negative-pressure tube, a piston and a piston rod; the center of the piston rod is provided with an axially-perforated through hole; the front end of the through hole passes through the top end of the piston, and is communicated with the negative-pressure tube; the back end of the through hole is connected with the drainage bag through the connecting tube; and both the drainage tube and the connecting tube are provided with clips. During replacement of drainage liquid in the negative-pressure tube in the device, the clip of the drainage tube is fastened, the clip of the connecting tube is released, and the piston is pushed, so thatthe drainage liquid can flow from a pipeline in the piston into the drainage bag; the entire process is performed in an enclosed cavity gap, so that the infection rate is lowered greatly; and the negative-pressure drainage device is convenient to use, and is sanitary.

Description

technical field [0001] The invention relates to the field of medical surgical instruments, and more specifically relates to a negative pressure drainage device. Background technique [0002] After surgery, postoperative hemorrhage and fluid accumulation often occur in the surgical site of the body, and drainage is usually required to improve wound healing efficiency. When some parts have excessive bleeding or need negative pressure suction, indwelling negative pressure drainage is required. In addition, negative pressure drainage devices are often used in the field of plastic and cosmetic surgery, the main purpose is to drain the parts or cavities that may bleed after surgery, and reduce postoperative complications, such as breast augmentation, breast reduction surgery, rhytidectomy , Dilator implantation, shaping after external ear reconstruction, skin flap surgery, etc. [0003] At present, some negative pressure drainage devices used clinically need to be connected to t...
