AI Technical Summary

Technical Problem

Existing disposable medical lung abscess interventional puncture negative pressure drainage devices use a large amount of materials, increasing manufacturing costs, and their shape is unstable during use, making them inconvenient to handle and place.

Method used

A negative pressure drainage device including a top cover, a container bag, and a bottom plate was designed. It adopts a support rod and float structure. The support rod can be flipped and snapped into the card holder to provide support. The float automatically stops the suction function by sealing the bottom ring with buoyancy. The support rod can be folded and stored for easy carrying.

Benefits of technology

The result is a compact structure for the drainage device, which is easy to operate and store, provides stable support, has a good sealing effect with the float, reduces material usage, and lowers manufacturing costs.

Abstract

The utility model belongs to the field of negative pressure drainage apparatuses, particularly relates to a medical disposable negative pressure drainage apparatus for lung abscess interventional puncture, and aims to solve the problems that an existing negative pressure drainage apparatus for lung abscess interventional puncture is high in material consumption, high in manufacturing cost and inconvenient to take and place due to the fact that the existing negative pressure drainage apparatus cannot be supported in shape when in use, and comprises a top cover, a containing bag and a bottom plate. An air suction vertical pipe is arranged at the top of the top cover, an injection connecting pipe is arranged at the top of the top cover, a liquid outlet valve is arranged on one side of the bottom of the containing bag, supporting rods are arranged on the two sides of the containing bag, the two supporting rods are supported between the top cover and the bottom plate, and scale marks are arranged on the sides, away from each other, of the two supporting rods. The supporting rod can be folded and stored, the overall structure is compact and convenient to carry and store, the blocking quality can be guaranteed through the design of the arc-shaped angle of the floating block, and therefore the overall structural design is more reasonable, all parts are connected more tightly, and operation is easier.
