Catheter that maintains blood flow by vascular bypass

摘要

The blood in the blood vessel without bleeding can be bypassed by bypassing the blood flow in the blood vessel where the surgery is performed and preventing the occurrence of illness due to stopping the blood flow of the organs fed from the relevant blood vessel. A catheter and vascular repair method that enables vascular repair surgery without impeding flow and maintains blood flow by vascular bypass in the course of vascular surgery performed for surgical procedures involving blood vessels in the human body , One balloon (3) at each position close to both ends thereof, a protective layer (4) located on the balloon (3), and the balloon (3) can be contracted and inflated, and the first path (2 ) And a second path (5), one end of which ends in the balloon (3) and the second path (5). Non-return valve device integrated with the rear end ( And a check valve device (7) for supplying substances such as air and liquid with an injection device for the expansion and contraction of the balloon (3), the first route (2) and the second route (5) ) From the outside, thereby preventing passage blockage when compressed, with varying lengths from the rear end of the balloon (3) to the rear surface of the catheter (1). The first segment (2) and the second segment (5) together with the integral protective segment (6) and the catheter device (1) exiting the blood vessel, or the catheter device (1) It is placed on the main body side of the catheter device (1), placed behind the balloon (3), and wider than the main body of the catheter device (1), so that it moves over the catheter device (1). Movable and open at both ends A cover (8) having a flexible structure, which may have a funnel-like, circular or elliptical shape, or other shape, a clamping device (9) which is used to fix the cover in place, An open tubular at least one third path (10) having one end positioned in the first path (2) and the other end positioned outside the first path (2) for liquid or air A third passage (10) used for pumping, and a connecting device (11) integrated with the outer rear end of the third passage (10) and connecting the external infusion device and the catheter The catheter apparatus (1) characterized by the above-mentioned.
