What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12582812B2 to Adavation LLC for a novel medical connector. The patent describes a male or female medical tubing or syringe connector that can be selectively locked in either a threaded configuration for secure attachment or a breakaway configuration. The breakaway functionality is designed to disengage via a pulling force, preventing patient harm if tubing becomes snagged.

This patent grant is primarily an intellectual property matter and does not impose new regulatory obligations on medical device manufacturers. However, it signifies a new technological development in medical device safety and connectivity. Companies involved in the manufacturing of medical tubing, syringes, or connectors should be aware of this patented technology, particularly concerning breakaway mechanisms and dual-mode (threaded/friction-fit) engagement, as it may impact future product development and design choices.

Abstract

A male or female orientated medical tubing or syringe connector that can be selectably locked in a threaded configuration or a breakaway configuration. The male connector includes opposing threaded sections and opposing non-threaded sections. The opposing threaded sections allow for the male connector's fully or partially threaded female counterpart to be screwed into place on attachment and unscrewed on detachment. The opposing unthreaded sections of the male connector allow for its partially threaded female counterpart to be engaged via a friction fit connection that does not require a screwing action. The male connector's opposing unthreaded sections also allows for its partially threaded female counterpart to be disengaged via a pulling force in the opposite direction of the male connector, which does not require an unscrewing action. This “breakaway” functionality helps to prevent patient harm if the patient's tubing becomes snagged.
