Modern medicine relies on a number of implantable devices to further patient care efficiently. These devices need to be non-abrasive so that the patient does not experience extreme discomfort at all times when wearing them. A vacuum evaporation system is used during the manufacturing process to solve a number of these complex problems and improve patient care.
The first step to vacuum evaporation involves placing a substrate into a vacuum sealed chamber, along with chemicals to be super heated. The pressure inside the chamber causes the chemicals to boil at room temperature, which breaks the chemicals into particulate matter. As the heat lowers, the particles bounce off the walls of the sputter coater, where the substrate receives a thin film of the chemical.
The process is especially useful when there are concerns of harming the substrate by boiling. The original inventor of this process was Henri Nestle, who used it to create the evaporated milk he needed to make his chocolate.
How these systems go from food preparation to patient care involves industrial usage. This technology is used extensively to treat waste water, which is useful for the environment at large. It is also used in the semiconductors that go into medical imaging systems. Vacuum chambers are used extensively for thin film coating of medical implants, like catheters.
These systems are typically clean, and they have low costs associated with managing them. This makes it cheaper and easier to mass produce devices that save lives.
