Brief Discussion on Adhesive Application in Medical Equipment Industry

Medical grade adhesives have been widely used in the medical device assembly industry. Basically all medical devices or diagnostic equipment may use medical grade adhesives. For medical device manufacturers, when deciding to choose an adhesive, they usually need to go through a lot of testing and verification to determine the performance of the adhesive.

>>>Standards and regulations
In the field of medical device manufacturing, people will pay more attention to the selection criteria of adhesives and the requirements for good bonding performance. Therefore, the medical device industry also has several important standards and regulations.

>>>Toxicity and biocompatibility
Adhesives used in medical devices need to be tested for their effects on cells (cytotoxicity), blood components (hemolysis), nearby tissues and overall biological systems.

>>>The toxicological properties and biocompatibility are generally tested according to the following guidelines:
(1) United States Pharmacopoeia(USP)-Class VI Standard
(2) International Standards Organization (ISO)-ISO-10993
Generally speaking, products are tested by independent laboratories, and the results are provided to equipment or adhesive manufacturers in the form of standard certification.

>>>Anti-sterilization
Most disposable and reusable medical devices need to be sterilized before they can be used.

Some products, such as endoscopes and surgical instruments, may require multiple sterilization cycles. The adhesive must withstand these processes without affecting the realization of the main functions.
