In many medical applications, polycarbonate is the best-in-class material and difficult to substitute in life-saving and life-enhancing applications.
In the neonatal unit, for example, clear, lightweight, shatter-resistant polycarbonate plastic provides a safety barrier that helps protect infants in incubators and allows medical personnel to monitor their health. Polycarbonate plastic provides the sturdy, clear material for the outside of the incubator as well as the housing for heating lamps and the supporting structure around them. The main benefits of polycarbonate include easy sterilization, high heat resistance and its tough and sturdy structure.
In some surgical devices, particularly those used in minimally invasive surgeries (also known as laparoscopic surgery), polycarbonate plastic provides unique benefits because of its ruggedness.
It can be used to make thin-walled parts, which allows smaller-scale medical devices and equipment to be made, and provides greater agility of movement in surgical procedures.
Because polycarbonate plastic withstands gamma rays, medical housings and equipment can be properly sterilized to protect patient health. Other unique benefits include its heat resistance, impact resistance, ignition resistance and design flexibility.
Drugs and Medicine
Polycarbonate plastic is frequently the preferred choice to make drug-delivery devices, from nebulizers to dialysis machines to needle-less safety syringes, because it can be easily sterilized and is durable. As more and more patients today, particularly the elderly, are directly involved in managing their more complicated medicines and medical procedures at home, cost-effective mobile therapy systems are increasingly necessary.
Polycarbonate plastic provides crucial benefits to allow such items as medical injection pumps to perform uniformly and consistently so that patients can self-administer medications with precision dosing. These types of pumps can be used to deliver a variety of medicines from chemotherapy to pain medicines to antibiotics and must be durable to withstand every day wear and tear as well as occasionally being dropped. The unique combination of features - transparency, impact resistance and easy sterilization - provided by polycarbonate are very important attributes for such medical equipment.
Epoxy Resin Medical Applications
Epoxy resins have numerous medical uses. These resins can be used as structural adhesives, in implants, in artificial joints, and in internal electronics, such as pacemakers. Special epoxy resins, nontoxic to cells and to which blood will not stick, are also used to make tubing, such as for intravenous or other types of catheters. Epoxy resins are used in making fiber optic devices, such as endoscopes, for remote examination of internal organs.
Pathological specimens are sometimes embedded in epoxy resins in preparation for microscopy.
Special epoxy resins are used in dentistry, to make models of the inside of the mouth. When exposed to particular wavelengths of light, these substances harden without shrinking or sticking to the teeth.
