Conversion insert for abdominal drainage tube

Abstract

The invention relates to a conversion insert of an abdominal cavity drainage tube, which comprises a tube body with a through hole, an inclined disc is arranged on the outer wall of the tube in the radial circumferential direction, and the inclined disc divides the tube body into a drainage tube. Tube connection hole and drainage bag connection hole, the end face of the inclined plane disc faces the drainage tube connection hole, and the inclined plane disc is provided with an air intake hole, a negative pressure suction hole and a flushing hole, the air intake hole, The negative pressure suction hole, the flushing hole and the through hole of the pipe body communicate with each other, the angle between the axis of the air inlet hole, the negative pressure suction hole and the flushing hole and the axis of the pipe body is 45°, and the slope The end face of the disc is perpendicular to the axis of the air inlet, the negative pressure suction hole and the flushing hole. The invention can directly change the single-chamber drainage tube inserted in the actual operation into a double-chamber negative pressure flushing drainage tube, which can not only achieve smooth drainage, but also avoid the pain of patients caused by improper insertion again.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a conversion insert for an abdominal drainage tube. Background technique [0002] Since the history of human surgery, "incision and drainage" has been the basic operation method. Whether it affects the operation effect and disease prognosis; the indications for surgical drainage can be divided into two categories: therapeutic and preventive. Therapeutic drainage includes limited abscess and pathological effusion, digestive fistula, and in order to reduce tension and compression, such as gas , fluid volume or tissue edema, etc., preventive drainage is suitable for secondary infection, bleeding, gastrointestinal fistula, fluid accumulation, gas accumulation, etc. after surgical treatment. [0003] In clinical medicine, because the material of the single-lumen drainage tube is soft and has few tubes, and the material of the double-lumen drainage tube is hard and has many ...

AI Technical Summary

Problems solved by technology

[0003] In clinical medicine, because the material of the single-lumen drainage tube is soft and has few tubes, and the material of the double-lumen drainage tube is hard and has many bifurcated nozzles, in actual use, it is difficult to determine whether the gastrointestinal tract, pancreas and other organs have When there is a fistula, the surgeon is more inclined to use a single-lumen drainage tube at the beginning of the operation, which is convenient for the operation. However, when the single-lumen abdominal drainage tube is passively drained, it is easy to have poor drainage, especially when the drainage fluid is viscous. At the same time, once the gastrointestinal tract, pancreas and other organs are found to have fistulas, it is necessary to switch to double-chamber negative pressure irrigation and drainage in time, and when switching to use, the original drainage tube must be pulled out and then inserted into double-chamber negative pressure irrigation and drainage. However, this method often cannot be placed at the fistula, which affects the normal operation and quality of the operation. At the same time, if the re-insertion is not in place, it is easy to increase the pain of the patient.
