Medical Devices
The precision electronic components in the cardiac pacemaker and the defibrillator implanted in the body require Parylene protection to prevent the erosion of body fluids, and at the same time provide good insulation for the metal parts.
The surfaces of the casing and the intubation required in endoscopic surgery are also coated with a layer of Parylene for selective insulation and lubrication effect.
The surface of the brain signal excitation electrode can be selectively coated with Parylene to obtain the desired smooth surface and partial insulation; the Parylene coating on the inner and outer surfaces of the needle can be used to close the fine pores on the surface and further obtain a smooth surface to reduce the adhesion of contaminating components.
In addition to insulation protection for the sensors, Parylene is also used as a protective material for harsh environment. The ultra-thin properties of Parylene provide good protection for sensors without changing the appearance, size, elasticity and weight of the sensor. At the same time, it provides good protection for the sensors. Sensors protected by Parylene include automobile sensors, corrosion environment sensors, biomedical sensors, acoustic sensors, etc.
This kind of metal artificial rehabilitation equipment needs to use parylene to solve the problems caused by the pores on the metal surface, and at the same time to protect the corrosion of body fluid, the human body tissue grows well on its surface and forms a perfectly normal appearance tissue.
The lubricity is improved by surfacial depositof Parylene, and the precise linear internal mold for injection molding also needs to be coated with Parylene, the Parylene coating on the surface can reduce the friction coefficient and is advantageous to demoulding. In addition, the good homomorphism of Parylene also helps to ensure the dimensional accuracy of the internal mold.
