Description

Technical Field

[0001] The present invention relates to the technical field of ascites puncture devices, and more specifically, to an adjustable-pressure and anti-leakage ascites puncture and drainage device. Background Art

[0002] Under normal conditions, there is a small amount of fluid (generally less than 200 ml) in the human abdominal cavity, which plays a lubricating role in intestinal peristalsis. Under pathological conditions, it may lead to an increase in the amount of fluid in the abdominal cavity. There are many causes of ascites, and the more common ones are cardiovascular diseases, liver diseases, peritoneal diseases, kidney diseases, malignant tumor peritoneal metastases, etc. A large amount of ascites will cause problems such as dyspnea and abdominal pain. Through abdominal paracentesis, a drainage tube is inserted from the anterior abdominal wall into the peritoneal cavity to drain the ascites out of the body, which can eliminate the diseases such as dyspnea and abdominal pain caused by ascites.

[0003] Most of the existing ascites puncture surgeries use puncture flexible tubes for puncture and drainage. However, the contact pressure between the tissues around the puncture site and the drainage tube is insufficient, resulting in the leakage of ascites between the puncture site and the catheter; at the same time, if too much ascites is drained, due to the sudden drop in abdominal pressure caused by the discharge of a large amount of ascites, it may lead to hypotension or other complications, such as dyspnea, rapid heartbeat, dizziness, and nausea, because the amount of ascites drainage is limited.

[0004] In view of this, we now propose an adjustable-pressure and anti-leakage ascites puncture and drainage device to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an adjustable-pressure and anti-leakage ascites puncture and drainage device, which has a simple structure and is easy to use, can effectively avoid the leakage of ascites, and can adjust the pressure.
