Dressing device for wound infection disruption and merged intestinal leakage of abdominal operation

Abstract

The invention discloses a dressing device for wound infection disruption and merged intestinal leakage of an abdominal operation, and belongs to the technical field of clinical medical dressings. The dressing device comprises a suction tube, a double cannula, a drainage tube, a liquid collecting cylinder and a PU (poly urethane) semi-transparent film for sealing a wound, wherein the double cannula consists of an inner tube and an outer tube, and a plurality of side holes are respectively formed in the outer tube and the inner tube; the suction tube, the drainage tube, and the outer tube and inner tube of the double cannula are connected by a cross valve, the liquid outlet end of the drainage tube extends into the liquid collecting cylinder, and the liquid collecting cylinder is connected with a center negative pressure device through a connecting tube; the exterior of the tube wall at the liquid inlet end of the suction tube is coated with composite sponge layers, and a plurality of through holes are formed in the tube wall; the number of composite sponge layers is three, the composite sponge layer for coating the tube wall of the suction tube is a PU foam sponge layer, and polyvinyl alcohol sponge layers are respectively arranged at both sides of the PU foam sponge layer. The dressing device has the advantages that the sealing is reliable, the operation is convenient and rapid, the drainage efficiency is high, the wound is reduced, the wound can be quickly healed, and the pain of a patient is 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 wound infection and dehiscence combined with intestinal leakage in abdominal surgery. Background technique [0002] Incision infection and dehiscence is a common complication after abdominal surgery. If intestinal leakage is combined, wound treatment is extremely difficult and the mortality rate is high. The characteristics of this wound include: ① Excessive exudate, mainly including purulent secretion and intestinal fluid from infected wound, the amount of exudate varies according to the severity of intestinal leakage and infection. ② Severe infection, the cause of infection is more complicated, early infection is mostly caused by primary disease, such as suppurative appendicitis postoperative incision infection is mostly caused by leftover bacteria, late infection can be combined with intestinal bacteria. ③ There is a lot of...

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
