<p>A stethoscope normally includes two tubular members which are pivotally mounted together and which have ear pieces on one end; and the headset is normally mounted on the head of the doctor or other user by using two hands, one on each of the two pivoted tubular members, and placing the ear pieces in the ears. A spring is normally connected to the other end of the head set and this spring will normally bias the tubular members and ear pieces toward one-another so that the head set will stay on the user's ears by itself. In accordance with the present disclosure, the two tubular members of the headset are provided with extensions which extend in the direction away from the ear pieces beyond the spring or the pivot point so that the ear pieces may be opened and the headset held with one hand as it is being put on or taken off from the ears of the user.</p> |
