Embodiment 1

[0011] Embodiment 1: An air bag 6 is fixed on the front periphery of the catheter 1 , and the inflatable tube 3 is connected to the air bag 6 .

[0012] The funnel-shaped pleura 4 and the expansion valve 5 connected at fixed intervals on the front periphery of the catheter 1 are fixed and closed between the funnel-shaped pleura 4 and the expansion valve 5 roots connected to the outer peripheral wall of the catheter 1 .

[0013] Correspondingly, an inflation hole 7 is opened on the outer wall of the conduit 1, and the front end of the inflation tube 3 is opened on the inflation hole 7.

[0014] The end of the inflation tube 3 is connected to the rear wall of the conduit 1 and connected to the air valve 2 .

[0015] The front end of the catheter 1 has a wedge-shaped oblique opening. A side hole 8 is opened on the front end wall of the conduit 1 . The rear part of the conduit 1 is connected with a control valve 9 .

[0016] The thickness or hardness of the swelling valve 5 is ...

Abstract

The invention discloses a medical valve plugging device, which relates to a catheter auxiliary device for guaranteeing human organ pipes smooth, such as the windpipes, the bronchus, the stomach tubes, the nephridium or the blood vessels and the like. The periphery of the front part of a catheter (1) is fixed with an air bag (6). An inflation tube (3) is switched in the air bag (6). By the design of the small supporting air bag (6), an expansion valve (5) and a lung membrane (4) are used to replace the original inflation or water jacket bag mode to make the plugging effect of a pipe (10) more reasonable and effective. The wider expansion valve (5) and lung membrane (4) enlarges the contact area and reduces the pressure on the mucous membrane so as to obviously reduce the compression on themucous membrane and effectively protect the visceral organs. And the reasonable change of the structure makes the operation safer, simpler and more convenient and makes the application prospect wide.

Description

technical field [0001] The invention relates to a novel medical catheter auxiliary device, which is a catheter auxiliary device to ensure the blockage or unblocking of human organ pipelines such as trachea, bronchi, gastric tube, renal tube or blood vessels, especially a medical valve occlusion device. Background technique [0002] In the known technology, inflatable cuffs are generally used to block all pipelines of human organ pipelines such as trachea, bronchi, stomach tube, kidney tube or blood vessels in clinical medicine, but due to the unsatisfactory working conditions of the airbags in the prior art, clinical application not effectively. [0003] The incidence and severity of all human pipeline lesions are not only related to the time of catheterization, but also closely related to other factors, such as the shape and pressure of the cuff, and the histocompatibility of catheter and cuff materials. The higher the balloon pressure The wall mucosal injury is more serio...
