Applications in Medical Materials
Due
to its excellent chemical inertness, non-toxicity, heat-resistance and
low-friction, PTFE is widely applied in biotechnology engineering, especially
in the scientific studies of Cardiovascular, Neurology, plastic surgery
and periodontosis. It can be used as the materials of medical devices and
artificial organs.
There
are PTFE tubes, bottles, filter papers, and filter fabrics among medical
devices. Expanded PTFE is used to
disinfect, to filter serum and virus and to separate bacteria from injection
drugs.
Expanded
PTFE can be produced into artificial blood vessels, heart valves, dialysis
membrane of artificial lung and reparative membrane of the Cardiac, all of
which are used as a substitute for human organ.
Expanded
PTFE is a six-surface crystal, and its molecules are put in order regularly. When
it is stretched, the mating surface between sliced crystals will slide under
the effect of force and heat, and small fibers and spaces will be formed. Therefore,
artificial blood vessel made of Expanded PTFE is not easy to be blocked,
possessing the performance of thrombus resistance.
The catheter
of gastro scope forceps made of expanded PTFE and rubber plastic film can be
deformed randomly. There is no foreign-body reaction, which will reduce the
pains of the patient.
