Body cavity drainage tube suit

Abstract

The invention discloses a body cavity drainage tube suit. The body cavity drainage tube suit comprises a front air bag sleeve, an outer cannula, an air bag inflation tube, a diluent tube, an air pressure adjusting tube and a body cavity wall sheath. According to the body cavity drainage tube suit, the structural design is ingenious and reasonable, due to the arrangement of the front air bag sleeve, the original pressing point contact is replaced with the surface contact of an air bag, the probability that tissue and organs inside a body can be damaged due to the fact that a drainage tube is left inside the body for a long time is greatly reduced, and the occurrence rate of common clinic complications such as digestive tract fistula and massive haemorrhage inside the pleuroperitoneal cavity is decreased obviously; due to the fact that the diluent tube and the air pressure adjusting tube are arranged inside the outer cannula, water and gas needed by the drainage end are provided; due to the arrangement of the body cavity wall sheath, the outer cannula can be rotated independently to achieve a better drainage effect in a drainage process, pain suffered by a patient can be greatly relieved due to the fact that the friction between the body cavity wall and the outer cannula is avoided when the outer cannula is rotated, the drainage tolerance of the patient is improved, damage is small, and the safety and the effectiveness of a drainage operation are effectively improved. In addition, the body cavity drainage tube suit has the advantages of being simple in overall structure, easy to manufacture, low in cost, and is capable of being popularized widely.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a body cavity drainage tube set used for drainage of body cavity fluid or necrotic tissue. Background technique [0002] As we all know, the control of surgical infection is a major focus and difficulty in the current medical field. Thoracic and abdominal drainage is one of the most important and main treatment methods for clinical surgical treatment of surgical infection. The quality of drainage often determines the patient's therapeutic effect and Disease progression and outcome. In patients with surgical infection, such as severe necrotizing pancreatitis and refractory abdominal infection caused by gastrointestinal fistula, which are common in clinical practice, abdominal drainage becomes an extremely critical treatment measure. Therefore, body cavity drainage has an irreplaceable position in modern medicine, especially in the treatment of surgical infection. [0003...

AI Technical Summary

Problems solved by technology

[0004] 1. At present, double-cannula or even triple-cannula are the most used for body cavity drainage, because the outer cannula is hard and can withstand the extrusion of surrounding tissues without deformation. The drainage effect is relatively good, but long-term contact or oppression of organs and tissues in the body cavity Or blood vessels, often produce complications that outweigh the gains, such as long-term compression of the gastrointestinal tract, resulting in local ischemic necrosis and gastrointestinal fistula, compression of large blood vessels and bleeding, etc., so its application range is greatly limited to some extent;

[0005] Soft drainage tubes such as rubber drainage tubes are often squeezed and flattened by surrounding organs or tissues, which greatly reduces the drainage effect

[0006] 2. Drainage in the body cavity often requires a long-term indwelling drainage tube. Since the drainage fluid is mostly necrotic tissue, it is often necessary to rotate the outer cannula during the drainage process to increase the drainage effect, but the rotation process often causes pain and discomfort for the patient, which is unacceptable and can increase drainage. Bleeding orifice infection possible

[0007] 3. After the current drainage tube is placed in place, the drainage tube is relatively constant. When the drainage around the drainage end is exuded or necrotic tissue is drained to a certain extent, the position of the drainage end needs to be changed and the tube needs to be replaced. Multiple intubations are required, which greatly increases the incidence of complications and patient suffering

[0008] 4. At present, the clinical fixation of the body cavity drainage tube is mainly by suturing the skin near the drainage tube and then using the tail thread to go around the tube wall and then tie a knot to prevent the drainage tube from prolapse. However, if the depth of the drainage tube needs to be adjusted Needle stitches need to be re-fixed after the stitches are removed, which increases the pain of the patient and the chance of infection
