A cardiovascular interventional device

Abstract

A cardiovascular interventional device, comprising an outer tube body, an inner tube body is arranged in the outer tube body, a first through hole is opened in the middle of the top surface of the inner tube body, a second through hole is opened in the middle of the top surface of the outer tube body, and the inside of the first through hole is There is a guide tube, the side of the guide tube is in close contact with the first through hole, the upper end of the guide tube passes through the second through hole and is located at the upper part of the outer tube body, and the side of the guide tube near the lower end is fixed with a ring-shaped first rubber stopper , the outer ring of the first rubber stopper contacts and fits with the inner wall of the inner tube. The invention has a simple and ingenious structure, which can ensure the cleanliness of the operation surface during cardiovascular interventional treatment, avoid cross-infection, and can conveniently inject the required medicine into the blood vessel of the patient during the treatment process, and can avoid the leakage of the medicine and the outflow when injecting the medicine. Contact with blood stains ensures the safety and sanitation of injection, and the invention is easy to use and can be used repeatedly.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a cardiovascular interventional device. Background technique [0002] At present, clinically, when performing cardiovascular interventional treatment for patients, the puncture needle is usually used to directly puncture the blood vessel or a common syringe is used to puncture the blood vessel, and then the syringe is removed from the puncture needle, and then the guide wire is sent into the blood vessel through the puncture needle. , such an operation is likely to cause blood spillage, pollute the doctor's operating surface, and easily cause cross-infection, and it is difficult for the current interventional therapy device to inject the drug needed for the treatment conveniently during the treatment, even if some devices can achieve this function , but it is not very convenient to use, and it is difficult to be safe and hygienic.
