Intra-abdominal effusion drainage device

Abstract

The invention relates to the technical field of medical instruments, in particular to an intra-abdominal effusion drainage device. The intra-abdominal effusion drainage device comprises a catheter, aconnector and a sterile drainage bag; one end of the catheter is communicated with one end of the connector; the other end of the connector is communicated with the sterile drainage bag; a first anti-reflux structure is arranged on the sterile drainage bag; the catheter is provided with a second anti-reflux structure. The catheter is kept in the abdominal cavity and the outer end of the catheter is communicated with the sterile drainage bag through the connector, the effusion in the abdominal cavity is drained to the sterile drainage bag through the catheter, and when the sterile drainage bagis full, the lower end channel of the sterile drainage bag is opened, and the ascites can be drained. The abdominal cavity puncture is not required to be repeated, and the safety is increased. The anti-reflux structure is arranged on the catheter and the sterile drainage bag, so that the drainage-out peritoneal effusion does not return to the abdominal cavity, and the probability of the ascites backflow secondary abdominal cavity infection is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intraperitoneal fluid drainage device. Background technique [0002] Under normal conditions, there is a small amount of fluid (generally less than 200ml) in the abdominal cavity of the human body, which lubricates the intestinal peristalsis. Any pathological state leads to an increase in the amount of fluid in the peritoneal cavity, and when it exceeds 200ml, it is called ascites. Ascites is only a symptom. There are many causes of ascites. The more common ones are cardiovascular disease, liver disease, peritoneal disease, kidney disease, nutritional disorder, abdominal metastasis of malignant tumor, ovarian tumor, connective tissue disease and adjuvant disease. Ovarian hyperstimulation syndrome after assisted reproduction, etc. [0003] When a large amount of ascites affects the patient's breathing or the patient's abdominal distension is severe and unbearable, tre...

Problems solved by technology

[0004] That is to say, in the prior art, for patients with intraperitoneal effusion, it is basically extracted once when needed, which makes the process both cumbersome and unsafe. Repeated incisions on the patient are prone to complications such as infection
