Abstract
A stethoscope head is combined with a watch having a sweeping second hand. A watch support member 30 extends from the stethoscope housing 20. The watch 32 rests upon the watch support member 30. A watch housing 38 encases the watch 32 and is secured to the watch support member 30. The watch support member 30 may be made of sound-absorbing material. Sound-absorbing material may be interposed between the stethoscope housing 20 and watch support member 30. The watch support member 30 and watch housing 38 may have cooperating threads so that the watch housing 38 may be screwed onto the watch support member 38. The sweeping second hand 34 of the watch may be easily viewed while the stethoscope is used.
