Abstract
A connector for joining one end of a rigid stethoscope ear tube to a multiple leaf binaural spring within a flexible tube that is attached to the stethoscope chestpiece, having a housing for rotatably supporting one end of the rigid ear tube so that it rotates about its own axis, with the housing and springs positioned inside the flexible tube so that the ear tube and the flexible tube are placed in aural communication. The housing is biased to place a holding force on the ear tube of between 2 and 10 pounds inches torque.
Claims12
A compact connector for joining one end of a rigid stethoscope ear tube to a multiple leaf binaural spring within a flexible y-tube that connects said rigid ear tube to the stethoscope chestpiece, the connector including:
- a housing for rotatably supporting one end of said rigid ear tube so that said ear tube rotates about the axis of said ear tube, said housing having an upper edge, and said housing being connected to the multiple leaf binaural spring so that said ear tube and said flexible y-tube, together with the multiple leaf binaural spring are placed in aural communication;
- and
- biasing means associated with said housing for placing a holding force on said ear tube, to resist a rotating motion of said ear tube within said housing, said force being between 2 and 10 pound inches torque.
