Multiple key position plug
First Claim
1. In a cable adapted to provide communications between a sensor and a pulse oximeter, said sensor having emitters adapted to transmit at least two wavelengths of optical radiation into a fleshy tissue site and a detector responsive to said radiation after attenuation by pulsatile blood flowing within said fleshy tissue site so as to generate a sensor signal, said pulse oximeter adapted to transmit drive signals via said cable to said emitters and to receive said sensor signal via said cable from said detector so as to calculate a corresponding oxygen saturation measurement, a plug configured to mate with a corresponding socket mounted on said pulse oximeter so as to mechanically and electrically connect said cable to said pulse oximeter, said plug comprising:
- an insulating plug body adapted to mesh with an insulating socket body of said socket;
a plurality of conductive plug contacts disposed within said plug body and adapted to insert into corresponding conductive socket contacts disposed within said socket body; and
a fixed plug key defined by said plug body, said plug key adapted to accommodate a socket key defined by said socket body at any of a plurality of key positions.

Abstract
A plug body is adapted to mesh with a corresponding socket body disposed on a pulse oximeter. Plug contacts are disposed within the plug body and electrically connected to conductors of a cable. The plug contacts are adapted to mesh with socket contacts disposed within the socket body so as to provide electrical communications between a sensor connected at a sensor end of the cable with the pulse oximeter connected at the monitor end of the cable. A fixed plug key of the plug body is adapted to accommodate a socket key of the socket body, where the socket key may be disposed at multiple key positions.

13. A plug disposed on a monitor end of a patient cable, said patient cable having a plurality of conductors extending between said monitor end and a sensor end, said plug comprising:
-
a plug body adapted to mesh with a corresponding socket body disposed on a pulse oximeter;
a plurality of plug contacts disposed within said plug body and electrically connected to said conductors, said plug contacts adapted to mesh with a corresponding plurality of socket contacts disposed within said socket body so as to provide electrical communications between a sensor connected at said sensor end and said pulse oximeter connected at said monitor end; and
a fixed plug key of said plug body adapted to accommodate a socket key of said socket body disposed at any one of a plurality of key positions, wherein said sensor comprises a plurality of emitters responsive to a drive signal communicated from said pulse oximeter so as to transmit light of at least two wavelengths into a tissue site having pulsatile blood flow and a detector responsive to said light after attenuation by said tissue site so as to generate a sensor signal communicated to said pulse oximeter, and wherein said pulse oximeter is adapted to derive an oxygen saturation measurement from said sensor signal. - View Dependent Claims (14, 15, 16)
