What is the use process and subsequent effects of angiographic catheter?

The angiographic catheter is a long rubber tube whose main function is to provide a guide for the contrast agent to be smoothly introduced into the blood vessel to produce a contrast effect. Therefore, a contrast catheter should meet the following basic conditions: the inner tube is smooth and can generate high flow rate; the imaging performance is high; the non-traumatic tip must have a very high original shape retention performance and is not easy to deform; the guide wire can be easily passed through, etc.

What are the selection criteria for angiographic catheter?

Selective contrast catheters have different shapes according to the requirements of different parts. For example, the catheters commonly used for several arteries on the aortic arch include Headhunter I, II, and III catheters and Simmon I, II, and III catheters. Catheters; RDC catheters and Simmon I, II, III catheters for renal arteries and veins; Cobra I, II, III catheters and SHK catheters for iliac arteries and veins. Most selective contrast catheters do not have side holes, and their maximum flow rate can reach 7-8ml/s. The selection of catheters used for the treatment of different external vascular sites is basically the same as the aforementioned selective contrast catheter. There is also a thrombolytic catheter used for treatment, which is designed with multiple side holes, and the length of the perfusion section can reach 7.cm, which can directly penetrate into the thrombus. Local perfusion therapy was performed.

What are the raw materials for the production of angiographic catheters?

Angiographic catheters consist of a catheter body, a catheter tip, and a catheter adapter. The manufacturing materials are: catheter body: nylon 12 containing bismuth oxychloride; catheter tip: nylon 12 containing tungsten; catheter seat: vinyl acetate and nylon; catheter body contains 304 stainless steel metal reinforcement mesh, and the outer surface of the catheter contains AQ Hydrophilic coating. The product is sterilized by ethylene oxide and is for single use. angiographic catheters are intended for use during angiographic procedures and are performed by physicians trained and experienced in angiographic techniques.

Angiography will not cause damage to the inner wall of the blood vessel. The catheter that enters the blood vessel during the process of using angiographic catheter should be a very thin and elastic material that can freely shuttle between blood vessels through blood flow. The process of angiography and stenting is an agreed process. Once the heart is stented, long-term maintenance is required. In the later stage of angiography without stenting, there is no need for medication to repair the vessel wall. But not getting the stent does not mean that the blood vessels are not blocked, but the degree of blockage does not exceed 85%. You can take some health care medicines to lubricate and soften blood vessels, and you can also take some blood-thinning medicines, such as aspirin, to keep blood vessels healthy.
