A dressing device for abdominal incision infection dehiscence combined with bile leakage

Abstract

The invention discloses a dressing device for abdominal incision infection dehiscence combined with bile leakage, comprising a suction tube, a drainage tube, a flushing tube, a lavage tube and a liquid collection bottle; the suction tube, the drainage tube and the flushing tube are connected through a three-way joint The liquid outlet end of the drainage tube extends into the liquid collection bottle, and the liquid collection bottle is connected to the central negative pressure through the connecting pipe; the pipe wall of the liquid inlet end of the suction pipe is covered with a sponge, and several channels are opened on the pipe wall placed in the sponge. There are several side holes on the wall of the free end of the irrigation tube, and the irrigation tube is connected to the irrigation tube through a double-chamber glass joint; it also includes a semi-permeable membrane for sealing the wound. The device has the characteristics of quickly closing the wound, reducing the wound surface, good drainage, fast healing, and less pain.

Description

technical field [0001] The invention relates to the field of medical dressings, in particular to a dressing device for abdominal incision infection dehiscence combined with bile leakage. Background technique [0002] Infection and dehiscence of surgical incision is a common complication of biliary tract surgery. If combined with bile leakage, wound treatment is extremely difficult. The characteristics of the wound include: ① Excessive exudate. It mainly includes purulent secretions and bile from infected wounds, and the amount of exudation varies according to the severity of bile leakage and infection. ②A lot of necrotic tissue. Bile is extremely irritating, and the leaked bile irritates the skin and subcutaneous tissue, resulting in a large amount of necrotic tissue in the wound. ③ The mortality rate is extremely high. The stimulation of bile can aggravate tissue edema, lead to full-thickness rupture of the abdominal wall, leakage of abdominal viscera, infection of the ...

Problems solved by technology

[0003] The traditional way is to change the dressing of the wound, but because the wound has a lot of exudate and necrotic tissue, it is only possible to keep the wound clean after changing the dressing several times a day, usually 4-10 times per day, which will This leads to a huge workload for doctors and great pain for patients.

In recent years, some people advocate placing a drainage tube at the outer opening of the bile leak to fully drain the bile. However, in the early stage of the wound, the sinus tract has not yet formed, so it is difficult to find the bile leak, and it is difficult to fully drain it; in the middle stage of the wound, although the sinus tract has been formed However, due to the large amount of necrotic tissue in the wound, it is also difficult to find the bile leak; in the later stage of the wound, after the bile leak is found, a drainage tube is placed, but there will still be bile leaking around the tube wall, making it difficult to achieve complete drainage
