Sanitary cover sleeve for medical device with electrical contact

摘要

A disposable cover sleeve serves is used to cover an electronic or optical medical device used for patient examination and/or treatment. The cover sleeve provides an environmental barrier for the medical device during patient examination to prevent environmental cross-contamination of different patients examined with the same medical device. The cover sleeve has an integrated device activation means such as a flexible contact bridge. The device activation means has an open and closed position. The open position is not in physical, electronic or magnetic contact with the control electronics of the medical device; whereas, the closed position closes a field or circuit between a first and second contact to selectively actuate or provide input to the control electronics that communicate with the radiation source.

主权项

1. A cover sleeve comprising:
a cover sleeve body having a first closed end, a second open end, an exterior surface and a lumen, wherein the first closed end of the cover sleeve body is designed to provide a close fit to a distal end of a medical device having an illumination source when the medical device is fully inserted into the lumen of the cover sleeve body; and a flexible layer integrally attached to the exterior surface of the cover sleeve body having a contact bridge mounted on an underside of the flexible layer facing the lumen of the cover sleeve body, wherein the contact bridge is positioned to physically contact a first contact and a second contact exposed on an outer surface of the medical device when a force is selectably applied to the flexible layer, wherein the physical contact between the contact bridge and the first and second contacts closes a circuit between the first and second contacts and wherein when the force is not applied to the flexible layer the contact bridge does not physically contact the first and second contacts and the circuit open between the first and second contacts.
