Abstract

The invention belongs to the field of medical instruments, and discloses a cardiovascular intervention therapy device which comprises a needle tube. A one-way valve is embedded into the front end of the needle tube, a rubber positioning piece is vertically mounted on the one-way valve, a push rod is movably mounted inside the needle tube, a hole plug is arranged inside the push rod, a rubber plugis fixedly mounted at the front end of the push rod and clamped inside the needle tube, a through hole is formed in the front end of the rubber plug, an elastic sealing diaphragm is mounted inside thethrough hole, a guide wire hole is formed in the rear end of the push rod and communicated with the hole plug, a push plate is integrally mounted at the rear end of the push rod, and a conical blockis arranged in the middle of the push plate. The one-way valve is arranged at a needle head of the cardiovascular intervention therapy device, when the needle head is inserted into a blood vessel, a clamping valve flap further clamps a guide wire under reverse thrust of blood pressure, reverse flow of blood is decreased, annular valve flaps are arranged in a needle cylinder and a piston, reverse flow of the blood is reduced to the minimum, surgical safety is greatly improved, pollution to a worktable top is avoided, and bacterial pollution is reduced.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to cardiovascular interventional treatment equipment. 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. . This operation is easy to cause blood to overflow, pollute the doctor's operating surface, easily cause cross infection, and bring great inconvenience to the doctor's surgical work; in addition, the doctor needs to carefully control the position of the puncture device. It is easy to puncture the blood vessel by moving, resulting in operation failure and adding great difficulty to the doctor. [0003] To sum up, the problems in the prior a...
