Guide wire importer capable of avoiding secondary puncture

Abstract

A guide wire importer capable of avoiding secondary puncture comprises a needle cylinder, a push rod, a piston, a hollow tube, a sealing gasket A, a guide core, a sealing gasket B and a pressure cap. The piston is arranged at the front end of the push rod. The front end of the push rod and the piston are movably arranged in the needle cylinder. Through holes are axially formed in the center of the piston and the center of the push rod. The pressure cap is provided with a guide wire hole and is fixed into an assembly cavity in the tail end of the push rod. The sealing gasket A, the guide core and the sealing gasket B are sequentially assembled in a cavity formed by the assembly cavity and the pressure cap. According to the scheme, the two sealing gaskets at the rear portion of the guide wire importer capable of avoiding secondary puncture are adjusted, the guide wire importer capable of avoiding secondary puncture can be used for extracting liquid without pulling a guide wire out, and whether a catheter is put in place or not can be judged; accordingly, there is no need to conduct verification through another injector; once it is found that the catheter is not in place, the ingoing depth of the catheter can be adjusted again, secondary puncture and secondary catheter implantation are avoided, the pain of a patient is relieved, the operating time is effectively shortened, and the operating cost is lowered.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a guide wire introducer for avoiding secondary puncture. Background technique [0002] At present, the process of implanting the guide wire introducer used in medical clinics into the catheter is to first implant the guide wire into the human body through the guide wire implanter, and then insert the guide wire into the catheter. Afterwards, the sealing effect is lost. In order to judge whether the front end of the catheter is in place, generally, after pulling out the guide wire, insert a syringe at the end of the catheter outside the body to extract body fluids, and judge according to the state of the extracted body fluids. If the catheter is not in place, you need to repeat the procedure. Puncture and catheter placement not only increase the pain of the patient, but also delay the operation time and increase the operation cost. Contents of the invention [0003] The purpose o...
