Abstract

The invention relates to the technical field of negative pressure drainage equipment, and particularly relates to an anti-blocking negative pressure drainage device for surgical operation. The anti-blocking negative pressure drainage device comprises a stent, wherein a drainage assembly is arranged above the stent and comprises a storage device, a drainage bag is arranged in a pressure bottle, a guide device is arranged at a suction port and comprises a guide pipe and a drainage pipe connected with the guide pipe, a pressurizing connector is arranged on the drainage pipe, a pressurizing air bag is connected to the outside of the pressurizing connector, and a first one-way valve is arranged at the joint of the pressurizing connector and the pressurizing air bag. The inside of the drainage pipe is pressurized through the pressurizing air bag, the drainage pipe is extruded from inside to outside after pressure intensity is increased, the diameter of the drainage pipe is increased, macromolecular substances can pass through the drainage pipe, and blocking is avoided.

Description

Technical field [0001] The present invention relates to the technical field of negative pressure drainage devices, and more particularly to a surgical anti-blocking negative pressure drainage device. Background technique [0002] The negative pressure attraction is to produce the negative pressure state of its attractive head by a certain method, and the substance outside the suction head is extruded to the suction head, thereby completing the tool of "attracting" effect, and can carry out the surgery during the implementation of surgery through a negative pressure drainage device Waste liquid for unified collection, and convenient operation. [0003] A Negative Pressure Director. The negative pressure drainer of the present invention includes a drain ball and a drain tube attached to the drain ball, the drainage tube, which is provided, and a sharp portion is provided on the filter. The present invention has a simple structure, easy to use, allows the drain to quickly enter the ...
