Internally fixed drainage tube

Abstract

The invention discloses an internally fixed drainage tube, A technical scheme comprise a drainage assembly and an airbag assembly, A drainage assembly includes a drainage bag and a drainage tube, At least one drainage hole is arrange at one end of that drainage tube away from the drainage bag, the airbag assembly includes an abdominal airbag, a first air injector connected to the abdominal cavityair bag, Press airbag, third gas injector, An abdominal wall airbag and a second air inject member, An abdominal cavity balloon is arrange between that abdominal wall balloon and the pressing balloon,A first connecting pipe is connected between the abdominal cavity air bag and the first air injector, A second connecting pipe is connected between the abdominal wall airbag and the second air injector. The pressing balloon and the third air injector are connected with a third connecting pipe, and the drainage pipe can be fixed without suturing the skin, so that the patient is free from pain caused by suturing the skin, and the drainage pipe improves the tightness between the incision and the drainage pipe, and prevents air from entering the abdominal cavity to breed bacteria and form intractable infection.

Description

technical field [0001] The invention relates to the field of medical instruments, and more specifically relates to an internally fixed drainage tube. Background technique [0002] Drainage tubes are widely used in clinical work. Most of the drainage tubes currently used are made of soft polyvinyl chloride. During the operation, an incision is usually made on the abdominal cavity, and then the drainage tube is placed in the incision, and the abdominal wall tissue is sutured with silk thread to fix the drainage tube. Cutting of the abdominal wall by sutures, weak knotting of sutures, or improper care can easily cause the drainage tube to slip or shift, leading to poor drainage and abnormal drainage of the drainage tube, which interferes with the doctor's judgment on the progress of the disease and affects the decision-making of treatment. At present, the outside of the drainage tube is fixed by skin sutures, but there is no way to fix the inside. Because the airtightness of t...

Problems solved by technology

Most of the drainage tubes currently used are made of soft polyvinyl chloride. During the operation, an incision is usually made on the abdominal cavity, and then the drainage tube is placed in the incision, and the abdominal wall tissue is sutured with silk thread to fix the drainage tube. Cutting of the abdominal wall by sutures, weak knotting of sutures, or improper care can easily cause the drainage tube to slip or shift, leading to poor drainage and abnormal drainage of the drainage tube, which interferes with the doctor's judgment on the progress of the disease and affects the decision-making of treatment. At present, the outside of the drainage tube is fixed by skin sutures, but there is no way to fix the inside. Because the airtightness of the suture is not high, the air in the abdominal wall enters the subcutaneous along the gap between the drainage tube and the abdominal wall tissue, which may cause subcutaneous emphysema or blood accumulation. Bacteria, leading to intractable infection in the later stage, seriously affecting the recovery of patients and easily increasing medical expenses. At the same time, due to the stretching of the sutures on the abdominal wall, patients have obvious postoperative pain
