The lubricating coatings that are used in the disposable medical devices decrease the amount of friction and improve their performance.
FREMONT, CA: For the disposable medical equipment, engineers use medical-grade lubricants or coatings that consist of greases, dry powders, and oil so that it becomes easy to move the delicate parts. These coatings decrease the friction and stick to the parts that shear, rock, slide, twist, or pivot. They even solve the issue of stiction that is generally observed in medical devices like cutting tools, hypo tubes, catheters, staplers, and other surfaces to surface assemblies. The lubricating coatings can also decrease the amount of friction on the treated parts, enhancing their performance. Today, there are many complicated medical devices, but without lubricating coating, it will be difficult for them to be commercially available.
Besides, the lubricating coatings are even utilized on the manufacturing equipment and assembly fixtures themselves so that they can increase the speed of producing plastic and metal components. These coatings are also used in surfaces and assembly like metal extrusions, chutes and slides, chains and pulleys, machine window guides and door tracks, and conveyors to offer their best performance. It is also utilized for releasing plastic parts from the injection mold die cavities.
However, every coating is not similar, and here are some primary factors to consider while selecting a lubricating coating for the medical devices.
Excellent solubility and low viscosity
Generally, the lubricating coatings are applied through wiping, dipping, or spraying. The carrier fluid or fluid utilized for dispersing the coating must be engineered so that it can dissolve or scatter the coating when the carrier fluid gets evaporated.
Good materials compatibility
The material of the lubricating coating must also be excellent. Even while using materials like glass, ceramic parts, metal, and plastic, it must be safe.
The lubricating coating must be non-flammable because it has to decrease the risk of fire while being applied. It is essential when such equipment is used in high-volume and high-speed production facilities. There are various mechanical assemble operations that are susceptible to static discharge due to which it is crucial to make it non-flammable for safety in storage and use.
Hostile to bioburden
The device makers must select a lubricating coating, a non-aqueous carrier fluid, to prevent the growth of bacteria and other biologic contamination. Moreover, as pyrogenicaly-inert, it must also be compatible with the EtO (Ethylene Oxide) and radiation sterilization procedures that are commercially utilized.
