Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing. The first step is to prepare the polymer material and the steel wire 1 set in the medical catheter; the second step is to extrude the prepared steel wire 1 into the steel wire guide groove 2 of the extruder, and the extruder Including die head device, described die head device comprises main material guide post 3, described guide post is provided with tapered guide cavity, core 5, mouth plate 4, described core 5 and mouth The templates 4 are provided with annular intervals with uniform thickness, and the annular intervals are connected to the diversion cavity through the diversion channel, and the diversion channel is formed from the diversion cavity to the annular interval. It is tapered and makes the wall thickness of the formed conduit gradually decrease. The core 5 is connected with a steel wire guide tube 6 in the opposite direction of the discharge, and the inner cavity...

Abstract

The invention relates to a processing method for medical treatment instruments, in particular to a processing method for an anesthesia catheter with a steel wire built in a catheter wall. The processing method for the medical catheter with the built-in steel wire is simple in operation and high in degree of automation. The anesthesia catheter with the steel wire built in the catheter wall is obtained through processes of raw material preparing, extrusion molding, scale mark printing, end socket drilling and the like. The processing method has the characteristics that the method is simple in operation, and obtained products are moderate in hardness, safe, reliable and the like.

Description

technical field [0001] The invention relates to a processing method of a medical appliance, in particular to a processing method of an anesthesia catheter with a steel wire embedded in the tube wall. Background technique [0002] The patent number is "ZL201120430889.9", and the patent name is: built-in steel wire type medical catheter, which includes a tube body, which is a hollow tube with openings at both ends; Installed in the tube wall of the tube body; the two ends and the middle of the tube body are transparent. The patented product of this structure is easy to bend and not easy to be damaged by discounts. At the same time, the tube wall is thin and maintains a certain hardness, so that the puncture can be carried out smoothly. However, the patent of this structural form is limited by technology and cannot be mass-produced. This problem needs to be solved urgently. Contents of the invention [0003] The object of the present invention is to overcome the deficienci...
