Catheter for clinical intravascular interventional treatment

Abstract

The invention discloses a catheter for clinical intravascular interventional treatment. The catheter for clinical intravascular interventional treatment comprises a filling pipe. A filling pipe limiting structure is arranged in the middle of the filling pipe. A connection catheter seat is arranged on the outer surface of one end of the filling pipe. The outer surface of one end of the connection catheter seat is fixedly connected with a second connection catheter opening, a protection and antifouling structure is arranged on the outer surface of one end of the second connection catheter opening, a connection outer-pipe is arranged on the outer surface of the other end of the filling pipe, an inflatable bone tamp is arranged on the outer surface of one end of the connection outer-pipe, anda catheter body is arranged on the outer surface of the front end of the inflatable bone tamp. According to the catheter for clinical intravascular interventional treatment, the filling pipe limitingstructure is arranged so that the position of the filling pipe can be limited, and the work of medical staff is prevented from being obstructed; an anti-blocking drug injection device is arranged so that the impact of an injected drug on blood vessels can be avoided, and a patient is prevented from feeling uncomfortable; and the protection and antifouling structure is arranged, the sanitation of an end opening of the catheter is conveniently ensured, and the next use is facilitated.

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
