Abstract

The invention relates to the technical field of medical instruments, and particularly discloses an angiography catheter and an angiography device.The angiography catheter comprises a catheter end, a catheter body and a reinforcing structure, and the reinforcing structure is arranged on the side, back to the catheter end, of the catheter body, so that the hardness of the catheter body is different, the catheter body detours in a blood vessel conveniently, and the angiography effect is improved. A liquid outlet is formed in the catheter end, the catheter body is connected to the side, opposite to the liquid outlet, of the catheter end, and a liquid passing cavity communicated with the liquid outlet is formed in the catheter body, so that a contrast agent or other medicine can flow through the liquid passing cavity, flow out of the liquid outlet and reach the diseased region. Therefore, radiography is carried out on the diseased region, and diagnosis of doctors is facilitated. Therefore, by arranging the reinforcing structure, pushing of the catheter end is guaranteed, meanwhile, the side, facing the catheter end, of the catheter body is convenient to bend in a blood vessel in a circuitous mode, collision to the blood vessel is reduced, discomfort of a patient is reduced, and the radiography efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an angiography catheter and an angiography device. Background technique [0002] As an interventional medical tool, angiography catheters are widely used in vascular diseases. When an angiography catheter is used, it needs to penetrate deep into the blood vessel, so it is usually made of an antibacterial composite polymer material. One end of an angiography catheter is extended to the lesion site through an artery and vein, and is used to deliver a contrast agent to produce an imaging effect, which is convenient for doctors to observe and diagnose the lesion site. [0003] However, due to the same overall hardness, some angiography catheters are not easy to detour in the venous blood vessels, and are easy to scratch the blood vessel wall, which brings discomfort to the patient. [0004] Therefore, the angiography catheter is not easy to detour in the blood vessel, which...
