A dressing device for wound infection and dehiscence after heart bypass surgery

Abstract

The invention discloses a dressing device for incision infection and dehiscence after heart bypass surgery, which comprises a connecting tube, a suction tube, a drainage tube and a liquid collecting bottle; the connecting tube, the suction tube and the drainage tube are connected through a three-way joint; The end of the suction tube is connected with the negative pressure center through the liquid collection bottle; the free end of the suction tube is provided with a suction cup, and the bottom of the suction cup is provided with a top layer of sponge; A plurality of side holes are opened on the tube wall; a lavage tube is inserted into the liquid inlet end of the drainage tube, and a plurality of side holes are set on the wall of the lavage tube placed in the drainage tube; the bottom sponge passes through the first half Sealed by a permeable membrane, the top layer of sponge is sealed by a second semi-permeable membrane. The device has the characteristics of fast wound closure, wound reduction, efficient drainage, promotion of new blood vessel formation, acceleration of granulation tissue regeneration, anti-infection, promotion of healing, and no pain.

Description

technical field [0001] The invention relates to the field of medical dressings, in particular to a dressing device for incision infection and dehiscence after heart bypass surgery. Background technique [0002] Heart bypass surgery is one of the most common procedures performed in cardiothoracic surgery. Incision infection and dehiscence is a common complication of heart bypass surgery, with an incidence rate of about 7%. The incision is a median chest incision, which has high tension and poor blood supply; in addition, the sternum split during the operation is fixed by steel wires, which are foreign objects in the wound. Therefore, the wound resistance to infection is extremely poor. [0003] The preferred way to deal with this type of wound is to expose and change the dressing in time, but the traditional dressing change and drainage effect is not good, it is easy to cause the infection to spread to the deep part, invade the sternum and cause osteomyelitis, and even caus...

Problems solved by technology

[0003] The preferred way to deal with this type of wound is to expose and change the dressing in time, but the traditional dressing change and drainage effect is not good, and it is easy to cause the infection to spread to the deep part, invade the sternum, cause osteomyelitis, and even cause chest infection, and the mortality rate is extremely high; even if local infection There is no spread, but because the tension of the wound is too high, the wound will become bigger and bigger for a long time; in addition, the blood supply of the incision is poor, and the growth of granulation tissue is difficult, so the healing is extremely slow
