ABSTRACT:
A uridom for use as an external male catheter in a urinary incontinence device is manufactured by thermoplastic processing, using as base material a non-preprocessed compound material based on one or more thermoplastic, polystyrene-based block copolymers, preferably polystyrene polyethylene/butylene polystyrene copolymers, the elasticity of which has been enhanced through addition of a paraffinic process oil.
In the thermoplastic processing a constricted tubular portion at one end of the device is produced by injection moulding in a tool, serving as drainage tube and connected to a tube, whereas a mainly cylindrical, thin-walled body portion (1) is produced integral with said tube portion by a subsequent controlled extrusion and blow moulding operation, during which operation the said tube portion is secured and retained in said tool, whereby not only said tube portion but also an adjacent end portion of the body portion are produced with controlled increased wall thickness as compared with the rest of the body portion.
