Device for forming head of precision medical catheter

Abstract

The invention discloses a device for forming the head of a precision medical catheter. The device comprises a die holder (1), a compressed air interface (2), a heater and a catheter head die (4), wherein the heater consists essentially of a heating module (31), a heating coil (32), a temperature sensor (33) and a radio frequency interface (34); the heating coil (32) is wound on the circumference of the heating module (31); the radio frequency interface (34) is connected with the outer end of the heating coil (32); and the temperature sensor (33) is arranged on the heating coil (32). The device is characterized in that the heating module (31) and the catheter head die (4) are set to be two single parts, the heating module (31) is a cylinder with an inner cavity, the catheter head die (4) is a cylinder with an inner cavity, the catheter head die (4) can be nested in the inner cavity of the heating module (31), and the outer circumference of the catheter head die (4) is in close fit and contact with the inner circumference of the heating module (31). The device has the advantages that the die is changed conveniently, the die is positioned accurately, the installation is easy and convenient, time and labor are saved, and the work efficiency is greatly increased.

Description

Technical field: [0001] The invention relates to the technical field of forming and processing of medical catheters, in particular to a forming and processing device for medical catheters made of polymer materials, specifically a precision medical catheter head forming device. Background technique: [0002] With the development of modern science and medical technology, medical polymer materials have been widely and deeply used in various fields of modern medicine due to their excellent performance. At present, they have become a new industry with high technology content and high added value. potential. Since the reform and opening up, although my country's medical polymer material products have made great progress, the market for high-tech and high value-added medical products such as interventional catheters required by modern medicine is almost eliminated due to factors such as hardware and software levels and funds. Monopoly of imported products. Therefore, it is of grea...

Problems solved by technology

This connection has the following defects and deficiencies: First, when installing the heating module, it must be ensured that the catheter head mold in the heating module is precisely in the middle of the radio frequency coil to ensure that the catheter head mold is heated evenly in all directions. Therefore, during the installation process, it is necessary to repeatedly adjust the position of the mold, which is time-consuming and laborious, and the positioning is quite difficult

If there is a slight deviation, uneven heating will appear, which will affect the product quality, and it is difficult to ensure the consistency of product processing

Second, when one type of product is processed and another type of product mold is replaced, the original processing type product mold, that is, the heating module and heating coil and other auxiliary parts must be disassembled, and another type of product mold must be replaced, so as to enter Difficult another model product mold installation process

Time-consuming and labor-intensive, seriously restricting the improvement of work efficiency
