A connector (10) is disclosed for providing a connection, for example, a battery pack (16) and a medical instrument (14). The connector includes a grommet (18), which flexibly secures an internal conductive post (24) and external conductive post (26) to the instrument. Drop-shaped external and internal sections 28 and 32 of grommet 18 cooperatively engage external and internal flanges 54 and 58 on the instrument to restrict rotation of the connector, while a central section 30 of the grommet has a circular cross section to provide a seal between the connector and the instrument in the event the connector does rotate. The external section of the grommet is compressed slightly by the battery pack upon insertion into the instrument. A connector constructed with these features can be easily removed from the instrument for servicing and seals the interior of the instrument as well as connections made to the external post.

Combined defibrillator and ECG monitor and recorder

An enclosure (10) for a device (86) for recording information onto a strip of printing medium (14) is disclosed, and includes a base (11), forming a cavity (84), and first and second covers (12, 13) pivotally secured to the base. The first and second covers move opposedly to each other between open and closed positions to allow replacement of the printing meduim, which is wound onto a spool. The base and a printhead (16) are pivotally coupled to the first cover by cover and printhead links (30, 58), enabling the printhead to move with and remain covered by the first cover when the enclosure is opened. A drive roller (17) is rotatably secured to the second cover and is biased against the printhead for advancement of the printing medium when the enclosure is closed. When the second cover pivots to its open position, the roller is withdrawn from the base, but remains continuously engaged to a drive motor (18) by a series of gears. The first and second cover meet when closed to form a printing medium exit slot, and are locked in their closed position by locking tabs (42) included on the first cover, locking notches (44, 45) included in the base and second cover, and the cooperative action of the cover and printhead links. Lifting of a release flange (50) included on the first cover unlocks the covers, allowing biasing springs (34, 40) to move the covers to their open positions. An ejector arm (52) attached to the second cover ejects the depleted printing medium spool upon opening of the enclosure.

Portable defibrillator/EKG monitor/EKG recorder

An EKG monitor/recorder and defibrillator which are contained in separate housings are mechanically interconnected by a tongue member located on an exterior surface of the housing of the EKG monitor/recorder and a groove member located on an exterior surface of the housing of the defibrillator. The groove member receives the tongue member with a translative, sliding fit to also permit easy disconnection and separation of the EKG monitor/recorder and the defibrillator. Electrical interconnection between the EKG monitor/recorder and the defibrillator is afforded by a pair of novel electrical slide connectors respectively located in the exterior surfaces of the housings in proximity to the tongue and groove members, with each electrical slide connector including a plurality of spaced-apart leaf spring contacts which, in assembly, extend parallel to the direction of translative movement of the EKG monitor/recorder and defibrillator housings. Circuitry is provided within the EKG monitor/recorder and defibrillator for providing EKG monitoring through paddle electrodes of the defibrillator by coupling the paddle electrodes to the EKG monitor/recorder through the pair of electrical slide connectors.
