Problems solved by technology

This process has several disadvantages: 1. The manual operation is cumbersome, because the glue has been glued, so the worker must wear gloves to operate, the convenience of the whole operation is very poor, and the efficiency is low; 2. The glue is uneven, because the manual threading During the process, it is difficult to avoid touching the glue on the metal wire, resulting in uneven glue; 3. The waste of glue is large. The core wire is dipped in glue and then threaded, and there will be dripping problems in the process, and the loss of glue will increase.

Abstract

The invention provides a preparation device and a preparation method for medical guide wires. The preparation device for medical guide wires comprises an automatic glue supply mechanism. The center ofthe automatic glue supply mechanism is provided with a through pore canal. The automatic glue supply mechanism comprises an insertion portion inserted into one end of a thin pipe and a glue supply portion exposed out of the thin pipe. The glue supply portion is provided with a glue injection port communicated with the pore canal, and during the movement of a core wire penetrating through the porecanal and into the thin pipe, glue is injected from the glue injection port of the glue supply portion to apply glue to the surface of the moving core wire. The core wire coated with the glue moves towards the inside of the thin pipe, so that the glue fills the gaps between the core wire and the inner wall of the thin pipe. The invention can realize simultaneous gluing and threading, and the gluebetween the thin pipe and the core wire of the prepared medical guide wire is more uniform.

Description

technical field [0001] The invention relates to the field of medical guide wires, and more particularly, to a preparation device and method for medical guide wires. Background technique [0002] The preparation method of the medical guide wire is to penetrate a metal wire in the middle of the tube, and fill the gap between the metal wire and the tube with glue, and completely bond and fix the two; the current process is to soak the metal wire in the glue first, The wire is then manually inserted into the inside of the tube. This process has several disadvantages: 1. The manual operation is cumbersome, because the glue has been glued, so the worker must wear gloves to operate, the convenience of the whole operation is very poor, and the efficiency is low; 2. The glue is uneven, because the manual threading During the process, it is difficult to avoid touching the glue on the metal wire, resulting in uneven glue; 3. The waste of glue is large. If the core wire is dipped in gl...
