The Hospital & Homecare Sprague has an exclusive design that features an improved valve mechanism that virtually eliminates acoustic leakage and a chest-piece key to facilitate after market service. Comes with five interchangeable chest pieces: two diaphragms (small and large), and three bells (3/4 in., 1 in., and 1-1/4 in.) to offer the most complete diagnostic capability. Also includes three different sized ear-tips for maximum comfort. Double tubing offers improved acoustic separation. Complete with accessory pouch and instructions. Overall stethoscope length is 30 in. Black.
