雙頭聽筒 (專業心臟科)｜力圖

【醫療器材】The Cardiology offers acoustical excellence in a traditional design. The solid stainless steel chestpiece with deep bell improves the low frequency response while the diaphragm allows the user to hear both high and low frequency sounds by simply alternating the pressure applied to the chestpiece. Other features include “two tubes in one” design, which means noise from tubes rubbing together is eliminated, non chill rims.
