A TUBULAR WORKPIECE FOR PRODUCING AN IMPROVED BALLOON CUFF TRACHEOSTOMY TUBE
摘要
<p>There is provided a tubular workpiece for blow-molding into an inflatable balloon component. The tubular workpiece is a raw tube having a lumen and composed of a thermoplastic polymer, the tube having an asymmetric wall thickness such that when the tube is preheated in a mold to a temperature sufficient to soften the material of the tube and inflated with a gas to generally uniformly stretch the material of the tube, the tube forms a balloon component. The balloon may be non-uniform in wall thickness depending on the type of mold used. The balloon may be attached according to conventional means to a hollow tube to produce a tracheostomy device.</p>
