Novel cardiovascular intervention therapeutic apparatus

Abstract

The invention discloses a novel cardiovascular intervention therapeutic apparatus, which comprises a syringe, wherein a check valve is connected to the left end of the syringe, a primary stage of annular valve flap is arranged in a guide thread hole in the left side of the syringe; a handle is arranged on the right side of the syringe; a syringe needle is connected to the left end of the check valve; a rubber locating sheet is connected to the middle of the check valve; a piston mechanism is arranged in the inner cavity of the syringe in a matched mode; the piston mechanism is connected to a push rod mechanism by virtue of a clamping groove; and the push rod mechanism sleeves inside the syringe by virtue of a locating ring. By virtue of the check valve on the syringe needle of the cardiovascular intervention therapeutic apparatus, a guide thread is further clamped by the clamped valve flap under the reverse thrust of blood pressure as the syringe needle is inserted in a blood vessel, so that the reverse outflow of blood is relieved; meanwhile, by arranging two stages of annular valve flaps in the syringe and the piston, the reverse outflow of the blood is minimized, so that the safety of an operation is greatly improved, the pollution of a working platform is avoided and bacterium pollution is relieved; and the therapeutic apparatus conforms to actual situations, and the therapeutic apparatus is convenient for popularization and promotion.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a novel cardiovascular interventional treatment device. Background technique [0002] In cardiovascular interventional treatment, the puncture needle is first inserted into the patient's blood vessel, and then the guide wire is sent into the blood vessel through the puncture needle. However, during the puncture, blood flows out along the puncture needle hole, which increases the complexity of the operation and the workload of the medical staff. In addition, after the puncture needle is inserted into the patient's blood vessel, the puncture needle cannot be accurately positioned, which increases the pain of the patient. To this end, we propose a new type of cardiovascular interventional therapy device. Contents of the invention [0003] The purpose of the present invention is to provide a new type of cardiovascular interventional therapy device to solve the problems raised in ...

AI Technical Summary

Problems solved by technology

However, in the process of puncture, blood flows out along the puncture needle hole, which increases the complexity of the operation and the workload of medical staff.

In addition, after the puncture needle is inserted into the patient's blood vessel, the puncture needle cannot be accurately positioned, which increases the pain of the patient.
