Subcutaneous negative pressure drainage apparatus for abdominal incision

Abstract

The invention discloses a subcutaneous negative pressure drainage apparatus for abdominal incision. The subcutaneous negative pressure drainage apparatus comprises a negative pressure drainage ball, a connecting tube, a piston, a hanging ring, a first negative pressure drainage tube, a second negative pressure drainage tube, side holes and a puncture needle, wherein the connecting tube is directly arranged on one side of the negative pressure drainage ball; one end of the connecting tube is connected with the piston; the other side of the negative pressure drainage ball is connected with the first negative pressure drainage tube and the second negative pressure drainage tube; the first negative pressure drainage tube is communicated with the negative pressure drainage ball; multiple side holes are formed in the second negative pressure drainage tube; the puncture needle is fixedly connected to the other end of the second negative pressure drainage tube. The subcutaneous negative pressure drainage apparatus disclosed by the invention has the beneficial effects of being capable of reducing the occurrence rate of abdominal incision effusion and incision infection, alleviating the pain, shortening the length of stay, reducing the hospitalization cost and alleviating the workload of doctors.

Description

technical field [0001] The invention belongs to the field of abdominal surgery, in particular to a subcutaneous negative pressure drainage device for abdominal incision. Background technique [0002] There are tens of millions of general surgery and obstetrics and gynecology operations in the country every year, and there are tens of millions of cases of abdominal surgery for patients with abdominal wall obesity, multiple operations or patients with diabetes. However, in abdominal surgery, for patients with abdominal obesity, multiple operations or patients with diabetes, problems such as abdominal wall subcutaneous fluid, fat liquefaction, and incision infection are prone to occur. [0003] The current Braun negative pressure drainage device used in thyroid surgery has the following disadvantages: the diameter of the drainage tube is small, and it is easy to block the side hole; the length of the negative pressure in the drainage tube is relatively short; and the cost is hi...
