Balloon catheter bonding device

Abstract

The invention provides a balloon catheter bonding device. The balloon catheter bonding device solves the technical problems of poor bonding effect and complex operation of an existing balloon catheterbonding device due to the adoption of a hot mold. The balloon catheter bonding device is provided with a machine base, a control mechanism, a hot air bonding mechanism and a balloon catheter fixing mechanism, wherein the control mechanism is provided with a controller; the hot air bonding mechanism is provided with a nozzle, a hot air pipeline and an adjusting device; the hot air pipeline and theadjusting device are connected with the nozzle, and the adjusting device is controlled to the controller to adjust the air volume and temperature of air flowing from the nozzle; the balloon catheterfixing mechanism is provided with a movable support; the balloon catheter is fixed on the movable support; the lower end of the movable support is provided with a movable track along the axial direction of a balloon catheter; the movable support is also provided with an executing mechanism for controlling the movable support to slide on the movable track, and the executing mechanism is connected with the controller; the front end of the nozzle is provided with a U-shaped opening with an outward opening; two side surfaces of the U-shaped opening are arranged up and down; the opposite inner surfaces of the two side surfaces of the U-shaped opening are correspondingly provided with an air outlet, and the balloon catheter is arranged in the U-shaped opening.

Description

technical field [0001] The invention relates to the field of production and processing of balloon catheters, in particular to a balloon catheter bonding device. Background technique [0002] The balloon catheter is mainly composed of a balloon as an expander, an outer tube fixed to the rear end of the balloon, and an inner tube inserted into both the balloon and the outer tube. The inner tube is used for inserting through the guide wire, and the expansion lumen provided between the outer tube and the inner tube can be used for circulating the fluid (contrast medium or saline, etc.) of the expansion balloon. During the production process of the balloon catheter, it is necessary to bond each part of the pipeline components. Since the product needs to enter the human body, the bonding method is mainly thermal bonding. [0003] The current bonding of balloon catheters mainly uses hot mold heating and bonding. The existing bonding devices for balloon catheters are prone to low b...
