A disposable flexible medical device or probe and a reusable connector are provided. The disposable probe comprises a flexible tube of resilient plastic having a central major lumen and two or more minor lumens formed in the walls of the tube. Flexible electrically-conductive wires of undulating configuration extend through the minor lumens for conveying electrical signals from the distal end of the probe within the human body to suitable external monitoring instruments. The proximal end of the probe is formed as a female connector having longitudinally extending contacts on the inside surface of the major lumen, the contacts preferably being formed as an integral part of the wires extending through the minor lumens. A relatively rigid reusable male connector is employed as a coupling means. It includes transversely extending arcuate electrical contacts arranged for engagement with corresponding contacts on the female connector, the arcuate contacts being arranged on a tubular member surrounded by a spaced concentric sheath. It further includes a passage extending therethrough for coupling the major lumen of the disposable probe to an external stethoscope earpiece or other device. A key and slot arrangement is provided for insuring that the male and female connectors are connected in a properly polarized manner and a visible indicator is provided for facilitating such proper connection.

A probe and connector comprising: (a) a disposable probe including a flexible tubular member having a central major lumen, said probe including a distal end and a proximal end; (b) a condition-sensing element disposed at said distal end; (c) a plurality of flexible conductors electrically connected to said sensing element, each of said conductors extending from said distal end to said proximal end of said probe; (d) the proximal ends of said conductors being disposed on the inner wall of said tubular member to form first contacts near the proximal end thereof; (e) said proximal end of said probe being formed to provide a female connector; (f) a relatively rigid reusable male connector having a plurality of second conductors extending therethrough and adapted to be connected to an indicating instrument, the ends of said second conductors being disposed on said male connector to form second contacts, said male connector being removably connected to said female connector with said second contacts engaging respective ones of said first contacts; (g) said first and second contacts being slidably movable relative to each other during engagement and disengagement thereof; and (h) said first contacts extending in a direction transverse of said second contacts, whereby the sliding movement during engagement and disengagement of said first contacts and said second contacts insures wiping action for removing any contamination from said contacts and achieving excellent electrical conduction.
