20130150729 | Sanitary cover sleeve for medical device with electrical contact - 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. | 06-13-2013 |
