Dressing device for abdominal surgical incision infection dehiscence combined with intestinal leakage

Abstract

The invention discloses a dressing device for abdominal surgical incision dehiscence combined with intestinal leakage, which belongs to the technical field of clinical medical dressings and includes a suction tube, a double sleeve tube, a drainage tube and a liquid collection bottle. The double sleeve tube consists of an outer tube and an inner tube. The outer tube and the inner tube are composed of several side holes; the outer tube and the inner tube of the suction tube, the drainage tube, and the double sleeve are connected through a four-way valve, and the liquid outlet end of the drainage tube extends into the liquid collection bottle , the liquid collection bottle is connected to the central negative pressure device through a connecting pipe; the pipe wall on the liquid inlet side of the suction pipe is covered with a composite sponge layer, and several through holes are opened on the pipe wall; the composite sponge layer is Three layers, covering the tube wall of the suction tube is a polyurethane foam sponge layer, and a layer of polyvinyl alcohol sponge layer is respectively arranged on both sides of the polyurethane foam sponge layer; it also includes a PU semi-permeable membrane for sealing the wound. The dressing device is reliable in sealing and convenient in operation, and can efficiently drain and reduce wounds, so that the wounds can be healed quickly and the pain of patients can be reduced.

Description

Technical field [0001] The invention belongs to the technical field of clinical medical dressings, and in particular relates to a dressing device for infection and dehiscence of abdominal surgical incisions combined with intestinal leakage. Background technique [0002] Incision infection and dehiscence are a common complication after abdominal surgery. If combined with intestinal leakage, wound treatment is extremely difficult and the mortality rate is high. The characteristics of the wound include: ① There is a lot of exudate, mainly including purulent secretions and intestinal juice from the infected wound. The amount of exudation varies according to the severity of intestinal leakage and infection. ②The infection is serious and the causes of infection are more complicated. Early infections are mostly caused by primary diseases. For example, most of the incision infections after suppurative appendicitis are caused by remaining bacteria, and later infections can be combined wit...

AI Technical Summary

Problems solved by technology

④ It is often accompanied by exposure of abdominal viscera. Local infection will cause aggravated tissue edema, resulting in full-thickness tissue dehiscence and exposure of abdominal viscera. The above factors will make healing extremely difficult, and severe incisional hernia will still form after healing

However, conservative dressing change has the following disadvantages: ①The number of dressing changes is too many, and the purulent secretions and intestinal juices of the wound are constantly exuding. Only by changing the dressing several times a day can it be possible to keep the wound clean. The number of dressing changes is 4-8 times

②The drainage is not good. Due to the shortcomings of the traditional dressing (gauze), even if the dressing is changed several times a day, it is difficult to fully drain the large amount of exudate and necrotic tissue in the wound

⑤The wound is getting bigger and bigger. Traditional dressing changes will fill the wound with a lot of gauze, so the wound may become bigger and bigger for a long time, which will also lead to difficulty in healing

⑥It is painful to change the dressing, the gauze will adhere to the new tissue, and the patient will have severe pain when changing the dressing to remove the gauze, which is very painful
