Seroperitoneum drainage tube

Abstract

The invention relates to the field of medical instruments, in particular to a seroperitoneum drainage tube. The anti-embedding drainage tube can prevent tissue in the abdominal cavity from being transferred into drainage holes during use after being put in the body of a patient. The anti-embedding drainage tube comprises a hard drainage tube with the drainage hole formed in the tube wall. The harddrainage tube is further sleeved with a layer of soft drainage tube with the drainage hole, a drainage gap is formed between the hard drainage tube and the soft drainage tube, and the drainage hole in the hard drainage tube is staggered from the drainage hole in the soft drainage tube. The tissue in the abdominal cavity can be effectively prevented from being transferred into the drainage holes,even when the tissue is transferred into the drainage holes, the amount of the transferred tissue is also small, pulling-out of the drainage tube is barely affected, and therefore no new pain is caused to the patient when the drainage tube is pulled out.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a drainage tube for peritoneal effusion. Background technique [0002] Peritoneal drainage is a commonly used technique in general surgery. It is used to drain the fluid in the abdominal cavity to the outside of the body, so as to reduce the adverse reactions of the human body and promote the recovery of the body. At present, the peritoneal drainage devices routinely used in clinical work are mainly hard or soft silicone drainage tubes of various specifications and models and plasma tubes made of rubber. Due to design or material problems, this drainage device has the following problems: [0003] (1) Intra-abdominal tissue is easily embedded and extubation is difficult: the abdominal drainage tube widely used in clinical practice has several drainage holes. Therefore, when the drainage tube is placed, tissues such as the greater omentum, intestinal fat, and even the edematous...

AI Technical Summary

Problems solved by technology

[0003] (1) Intra-abdominal tissue is easily embedded and extubation is difficult: the abdominal drainage tube widely used in clinical practice has several drainage holes. Therefore, when the drainage tube is placed, tissues such as the greater omentum, intestinal fat, and even the edematous intestinal wall in the abdominal cavity are easy to "transfer" into the drainage hole, and because the material of the drainage tube is too hard or too soft, the embedded tissue is easy to enter. It is not easy to come out, which often leads to difficulty in extubation. When it is forcibly pulled out, it will bring pain to the patient and inconvenience to the clinical work.

[0004] (2) The material and drainage effect of the existing products are not good: the material of the existing clinical drainage tube is too hard or too soft

Common drainage tubes made of silicone material are hard, not easy to bend in actual use, and are easy to rub against abdominal viscera; while plasma drainage tubes made of rubber are soft and easy to be compressed, resulting in poor drainage
