Problems solved by technology

[0003] When medical staff in the Department of Cardiology perform cardiovascular interventional operations on patients, they need to use disposable interventional devices. Commonly used interventional devices have needle tubes and needles, and elastic sealing devices are provided in the needle tubes to prevent blood from flowing out during interventional operations; but When such a device is inserted into the guide wire, the guide wire needs to pierce the sealing device. Due to the need for manual operation, there is a risk of infection, and the safety protection for the patient is not enough

Abstract

The invention discloses a cardiology department intervention device for preventing excessive bleeding. The cardiology department intervention device comprises a syringe needle, a needle cylinder and a push-and-pull rod; the needle cylinder is composed of an inner cylinder and an outer cylinder; the syringe needle is connected to the outer cylinder of the needle cylinder; the inner cylinder is provided with the push-and-pull rod with a piston; a guide wire pipe is arranged on the push-and-pull rod and penetrates the piston; an elastic sealing cover is arranged at the position, on the surface of the piston, of the guide wire pipe; a guide wire is fixed to the elastic sealing cover; in the manufacturing process, the guide wire is placed on the guide wire pipe to be fixed to the elastic sealing cover; time waste caused by the fact that the elastic sealing cover is punctured through the guide wire in the operation process is avoided; pains of patients are reduced; and the operation time is shortened. Meanwhile, the infection risks caused by manual operation are avoided. The cardiology department intervention device is simple in structure, convenient to use, safe in use and suitable for wide popularization.

Description

[0001] technical field [0002] The invention relates to an interventional device for preventing massive bleeding in the department of cardiology. Background technique [0003] When medical staff in the Department of Cardiology perform cardiovascular interventional operations on patients, they need to use disposable interventional devices. Commonly used interventional devices have needle tubes and needles, and elastic sealing devices are provided in the needle tubes to prevent blood from flowing out during interventional operations; but When such a device is inserted into the guide wire, the guide wire needs to pierce the sealing device. Due to the need for manual operation, there is a risk of infection, and the safety protection for the patient is not enough. Contents of the invention [0004] (1) Technical problems to be solved [0005] In order to solve the above problems, the present invention proposes an interventional device for preventing massive bleeding in the D...
