Guiding steel wire guiding method and device in subclavian vein catheterization

Abstract

Provided is a guiding steel wire guiding method in a subclavian vein catheterization. At first, magnetic materials are arranged on a guiding steel wire, and in the process that the guiding steel wire is propelled from the tail end of a needle cylinder to the top end of the needle cylinder, a magnet guide device is utilized to absorb the top end of the guiding steel wire and is arranged outside a guiding steel wire top end path arranged in advance. A guiding steel wire guiding device comprises a puncture needle cylinder, wherein a syringe needle is arranged at the top end of the needle cylinder, a piston is arranged in the needle cylinder and provided with a guiding steel wire channel, the guiding steel wire is arranged in the guiding steel wire channel, the top end of the guiding steel wire penetrates through an inner cavity of the needle cylinder and a needle hole in the syringe needle, the magnet guide device is arranged on the outer side of the top end of the guiding steel wire, and an interval is arranged between the magnet guide device and the top end of the guiding steel wire. According to the guiding steel wire guiding method and the guiding steel wire guiding device, the guiding steel wire can avoid entering abnormal parts of jugular veins and the like, the success rate of subclavian vein puncture is obviously improved, and pain and financial burdens of patients are lightened. Therefore, the method is safe, noninvasive, economical, and environment-friendly.

Description

technical field [0001] The present invention relates to articles for human life, in particular to a medical device, in particular to a puncture device, in particular to a guide wire guiding method and device in subclavian vein catheterization. Background technique [0002] Central venous catheterization is an important means to quickly, safely and effectively establish deep venous access to rescue critically ill patients. It has been widely used in perioperative blood transfusion, intravenous hypertrophic nutrition therapy, central venous pressure measurement, insertion of pulmonary artery catheter, and placement of pacing catheter through vein. The commonly used puncture sites are femoral vein, internal jugular vein (Internal Jugular Vein, IJV), subclavian vein (Subclavian Vein Catheterization, SVC). Among them, the subclavian vein approach has the advantages of fixed position, less irritative vein wall collapse in shock state, less restriction of patient's activities, les...
