Novel drainage catheter with developing rings

Abstract

The invention relates to a novel drainage catheter with developing rings. The novel drainage catheter comprises the developing rings and a drainage catheter assembly, wherein the drainage catheter assembly comprises a front part and a back part; a front end part is arranged at the front end of the drainage catheter assembly; a tail end tip is arranged at the tail end of the drainage catheter assembly; the developing rings are respectively arranged at the front end of the drainage catheter assembly and a part, being 50 to 100 mm away from the tail end tip, of the drainage catheter assembly; each developing ring is tightly matched with the outer wall of the drainage catheter assembly. The novel drainage catheter has the beneficial effects that the developing rings can be clearly displayed in real time by ultrasound equipment and other imaging equipment, so that a doctor can track the position of the novel drainage catheter during catheterization, the problem that the drainage tube is not catheterized in a proper drainage area or complications are caused by repeated puncture after detaching of the drainage tube is solved, the one-time success rate of catheterization can be greatly improved, the incidence of the complications is lowered, and the pain of a patient is relieved; the structure is simple and reliable; the production is easy; the cost is low; the use is safe, convenient and reliable.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device that can be clearly and real-time displayed with the assistance of ultrasound and other imaging equipment, so that doctors can track the position of the drainage tube in real time when placing the tube, and avoid the problem that the drainage tube is not placed in the correct drainage area or falls off. A new type of drainage catheter with a developing ring that causes complications due to repeated puncture of the tube. Background technique [0002] Drainage tube is a commonly used consumable. There are many types of drainage tubes used clinically, which can be used for pleural effusion, peritoneal effusion, pericardial effusion, bile, digestive juice, postoperative encapsulated effusion, cystic fluid, urine , pus and other liquid drainage. Its purpose is to guide the fluid accumulated between human tissues or body cavities to the outside of the body, relieve tissue compr...

Problems solved by technology

[0004] So far, many kinds of drainage tubes have been developed around the world, and many methods have been thought of to make them real-time displayed through ultrasound and other images, but the actual effect is often not ideal, and there are many restrictions in use, or it is inconvenient, or the operation takes a long time. , or unable to manufacture, etc.
