Polymer Tribology in Safety Medical Devices: Retractable Syringes

We analyze an example of the application of polymer tribology to create a safety medical device, namely a retractable syringe. In service at various stages either lowor high-dynamic friction is needed. Our work focuses on a VanishPoint® nonreusable safety syringe manufactured by Retractable Technologies, Inc., Little Elm, TX. Different medical-grade materials strongly affect the performance of ...

Bio-tribology and Its Applications in Medical Sciences - a Review

Tribology is the science of rubbing, friction and wear. When biological systems especially human joints such as knees, hips etc which continuously move relative to one another are studied, tribology becomes biotribology. To understand the wear performance of the implant and effects of synovial fluid principles of biotribology are required. In this paper few papers are reviewed related to applic...

Wearable Medical Devices

A wearable medical device can be defined as a device that is autonomous, that is noninvasive, and that performs a specific medical function such as monitoring or support over a prolonged period of time. The term ‘‘wearable’’ implies that the support environment is either the human body or a piece of clothing. Handheld and portable devices are therefore not strictly speaking wearable, but this d...
