Dressing device for bile leakage of abdominal incision infection split and merging

Abstract

The invention discloses a dressing device for bile leakage of abdominal incision infection split and merging. The device comprises a suction tube, a drainage tube, a washing pipe, a lavage tube and a liquid collection bottle; the suction tube, the drainage tube and the washing pipe are communicated by a three-way connector; a liquid outlet end of the drainage tube extends into the liquid collection bottle which is connected with central negative pressure by a connecting pipe; the outside of a pipe wall of a liquid inlet end of the suction tube is wrapped with sponge, and the pipe wall arranged in the sponge is provided with a plurality of through holes; a pipe wall of a free end of the washing pipe is provided with a plurality of side holes; the washing pipe is connected with the lavage tube by a double-chamber glass connector; the device further comprises a semipermeable membrane used for closing the surface of a wound. The device has the characteristics of closing the wound rapidly, reducing the surface of the wound, realizing good drainage, quick healing and little suffering, and the like.

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
