An anesthesiologist or stethoscope mold is a receiver with a ring. Attached is a metal adaptascope with 1 ft. of tubing, more if requested. We recommend a vent for maximum comfort. Either can be made in any material. Lucite is the most popular. If requested we can make a stethoscope mold a full shell with an open sound channel for the stethoscope tip. We can also make this mold with a sound bore and tubing for use with a hearing aid.
