A METHOD OF MAKING AN IMPROVED BALLOON CUFF TRACHEOSTOMY TUBE

摘要

the present invention is a differential thickness of the balloon with the manufacturing methods to provide. The method uses a tube made of a thermoplastic polymeric material disposed in the asymmetry of the mold. The material tube is, at a temperature in the mold is pre-heated to soften the material of the pipe material, while still allowing for the longitudinal shrinkage of the tube material, is expanded to a material of the material pipe to the gas so that substantially uniformly increased, the balloon to form. As a result, the completed balloon has differential wall thickness of the upper region has a thickness of about 15 to about 30 , the lower region has a thickness of about 5 to 15 . ;
