Embodiment Construction

[0030] As mentioned in the background art, the prior art adopts butt joint technology to realize the connection between the head and the body of the insertion tube with different materials, which results in high cost of the PICC catheter. In order to solve the above problems, the present invention proposes to use different colloids alternately and uninterrupted extrusion molding technology to realize the connection between the insertion tube head and the body with different hardness, and the cost of extrusion molding technology is low.

[0031] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] The following firstly introduces the manufacturing method of the PICC catheter and the extruder used in one embodiment.

[0033] In one embodiment, the manufacture of this PICC catheter adopts such ...

Abstract

Provided is a preparation method of a PICC conduit. Differing from the scheme of using two types of materials to form a PICC conduit in a butt joint mode, the preparation method of the PICC conduit adopts a technique of colloid extrusion molding. Discharging of a first colloid and developing glue and discharging of a second colloid and the developing glue are controlled separately; since the hardness of the solidified first colloid is pretty high, the solidified first colloid can be utilized to form a PICC embedding pipe body with high hardness; since the hardness of the solidified second colloid is pretty low, the solidified second colloid can be utilized to form a PICC embedding pipe tip with low hardness; the connection of the embedding pipe body and the tip can be achieved through alternate and continuous feeding of the two colloids, and meanwhile, the production cost is pretty low.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for making a PICC catheter. Background technique [0002] PICC (Peripherally Inserted Central Catheter, a catheter from the peripheral vein to the superior vena cava) catheterization can directly deliver the nutrient solution or drug solution to the central vein with large blood flow and fast flow rate during radiotherapy and chemotherapy, thus avoiding the need for drug solution Stimulation of peripheral veins with small blood flow and slow velocity has gradually been widely used in postoperative clinics in recent years. [0003] In use, the PICC catheter is inserted together with the needle. Specifically, the PICC catheter includes an insertion tube suitable for being inserted into the human body and an indwelling tube suitable for being located outside the human body. There is a metal guide wire in the insertion tube. After the insertion tube enters the human...
