Nurse Jackie

This thread isn't really hitting the heights that the title suggested.... :D

THe grey thing in the middle where the two tubes meets is just a sealed box joing the tubes. Not in to the modern stethoscopes, but the old ones consisted of a mere membrane at one end to transfer the sounds of the heart/lungs etc. Normally the membraned side is used for higher frequency noise such as heart and lungs, and the bell is is used for lower sounds like bowels moving.

The sound carries up the hollow tubes, and in to the ears.
