Supreme Cartridge Heaters and the Manufacture of Catheter Tubing

Many people at some stage in their lives will visit their GP with urinary tract complaints, either having difficulty in controlling their bladder function or unable to successfully empty their bladder. This may be a consequence of bladder muscle deterioration, post-operation requirements or because the individual was born with a specific medical condition.

Our bladder plays a vital role in removing waste product from the body. Waste is initially filtered by the kidneys and turned into urine which is passed into the bladder for later excretion out of the body via the urethra. Bladders that cannot effectively carry out this function are likely to develop infections, causing the individual pain and discomfort.

Bladder function failure need not become an embarrassing and life inhibiting condition. Treatment of the condition can be easily managed through urinary catheterisation, either externally or internally fitted depending on individual care needs.

A urinary catheter is, usually, a thin, plastic, flexible piece of tubing that is inserted into the bladder either via the urethra or by a channel surgically made in the patients abdominal wall. Urine passes directly from the bladder through the catheter tubing into an external drainage bag, removing the need for the patient to pass urine themselves.

Catheter tubing is manufactured using the process of profile extrusion. The process requires the melting of raw plastic material (in which cartridge heaters play an intrinsic role), that is then forced through a die to produce long lengths of tubing. The lengths of tube will later be cut to specified lengths along with other finishing stages.
