A catheter for clinical endovascular interventional therapy

Abstract

The invention discloses a catheter for clinical intravascular interventional treatment, which includes a filling tube, the middle part of the filling tube is provided with a filling tube limiting structure, the outer surface of one end of the filling tube is provided with a connecting catheter seat, and the connecting catheter The outer surface of one end of the seat is fixedly connected with the No. 2 connecting conduit port, and the outer surface of one end of the No. 2 connecting conduit port is provided with a protective antifouling structure, and the outer surface of the other end of the filling tube is provided with a connecting outer tube. The outer surface of one end of the outer tube is provided with an expandable balloon, and the outer surface of the front end of the expandable balloon is provided with a catheter main body. The invention can limit the position of the filling tube through the filling tube limit structure, avoiding hindering the work of medical staff, and using the anti-blocking injection device, can avoid the impact of the injected drug on the blood vessel, avoid the discomfort of the patient, and protect the anti-fouling The structure is convenient to ensure the sanitation of the catheter port for the next use.

Description

technical field [0001] The invention relates to the field of clinical medical devices, in particular to a catheter for clinical intravascular interventional treatment. Background technique [0002] A catheter for clinical intravascular interventional therapy is a catheter used in clinical medical treatment for intravascular interventional therapy. It is easy to use and has been widely used. The functional requirements of therapeutic catheters are also increasing. [0003] During use, a catheter for clinical endovascular interventional therapy can complete the following operations: In cardiac interventional surgery, the balloon catheter is inserted into the blood vessel by percutaneous puncture technology under the guidance of medical imaging equipment. For the stenosis area, the balloon is inflated under strict monitoring to expand the stenosis area of ​​the blood vessel, thereby achieving the purpose of restoring the diameter of the lumen and accelerating blood circulation...

AI Technical Summary

Problems solved by technology

[0004] Although the existing catheter for clinical intravascular interventional therapy is simple in structure and easy to use, it has a single function. It is inconvenient to fix the position of the filling tube in the existing catheter for clinical intravascular interventional therapy. It may hinder the treatment work of the medical staff when it is released, and it is inconvenient to a certain extent. When the existing catheter for clinical endovascular interventional therapy is injecting drugs to the patient during the working process, the injection port is easily blocked by the blood vessel. It is inconvenient for the injection of drugs, and it is easy to cause a certain impact on the blood vessel, which has certain adverse effects. The existing catheter for clinical intravascular interventional therapy will be easily infected by dirt at the connection of the two catheter ports during use, and has certain adverse effects. Inconvenience, for this reason, we propose a catheter for clinical endovascular interventional therapy
