Dressing device for infected dehiscent incisional wound after heart bypass surgery

Abstract

The invention discloses a dressing device for an infected dehiscent incisional wound after heart bypass surgery. The dressing device comprises a connecting tube, a suction tube, a drainage tube and a liquid collecting bottle, wherein the connecting tube, the suction tube and the drainage tube are communicated through a tee junction; the free end of the connecting tube is communicated with a negative pressure center through the liquid collecting bottle; the free end of the suction tube is provided with a sucker; the bottom of the sucker is provided with a top layer of sponge; the tube wall of the free end of the drainage tube is coated with a bottom layer of sponge, and the tube wall of the drainage tube arranged in the bottom layer of sponge is provided with a plurality of side ports; liquid inlet end of the drainage tube is internally provided with a lavage tube in an inserting manner, and the tube wall of the lavage tube arranged in the drainage tube is provided with a plurality of side ports; the bottom layer of sponge is sealed by a first semipermeable film; the top layer of sponge is sealed by a second semipermeable film. The dressing device has the characteristics that the wound can be rapidly closed, the wound surface is lessened, efficient drainage is realized, the formation of new vessels can be promoted, the regeneration of granulation tissues is quickened, anti-infection and healing promoting of the wound are realized, no pain occurs and the like.

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
