Abdominal puncture drainage device

Abstract

The present invention relates to the field of medical devices and particularly to an abdominal puncture drainage device. The abdominal puncture drainage device comprises a drainage main pipe and a puncture needle arranged in the drainage main pipe, wherein the drainage main pipe is of a hollow structure, an injection branch pipe, a flowmeter, a speed regulation switch and a drainage branch pipe are sequentially arranged on the drainage main pipe, the injection branch pipe is connected with an injector through a one-way valve, the drainage branch pipe is connected with a drainage bag through the one-way valve, the drainage bag is connected with a negative pressure ball through an air pipe, and the negative pressure ball is provided with an air exhaust valve; a tail part of the puncture needle is provided with a heparin cap, the heparin cap is connected with a positioning plate through a cotton thread, a pressing plate is arranged on the positioning plate, and the pressing plate is connected with a positioning ring through a telescopic rod; and after the puncture needle completes puncture by utilizing the positioning plate, the puncture needle is pulled out, and the heparin cap covers a tail part of the drainage main pipe. The abdominal puncture drainage device has characteristics of simple operation, high puncture success rate, less postoperative complications, etc.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an abdominal cavity puncture and drainage device. Background technique [0002] At present, clinically, ascites can be produced when the heart, liver, kidney, etc. have lesions. When the intraperitoneal fluid increases by more than 200ml, it can be regarded as a symptom. While finding the cause and treating symptoms clinically, ascites drainage is also required. Doctors usually implement paracentesis and drainage for patients with peritoneal effusion, and drain the ascites for the patient to relieve the patient's pain. Conventional B-ultrasound-guided abdominal puncture and drainage, the positioning is not accurate, and it is impossible to puncture deep lesions and lesions with narrow or small puncture gaps, and the success rate of the operation is low, resulting in many postoperative complications. difficult; after the puncture is completed, the drainage speed is not easy to gr...
