Embodiment Construction

[0029] turn to Figure 15 A to Figure 15 C, shows a typical stethoscope of the prior art in which the stethoscope diaphragm is held in place to the stethoscope body by a ring 12 with a mating threaded closure. Two different diaphragms that may fit within the ring 12 are shown. The movement of the diaphragm 10 is limited by its rigid axially outer suspension. It is essentially the short, stiff tube that connects the larger diaphragm surface 10 to the stethoscope body. Diaphragm 14 uses a viscoelastic annular suspension 16 as a means of enhancing its ability to move in concert with body vibrations. Diaphragms 10 and 12 may be made of copper to create a stethoscope with antimicrobial properties. However, the diaphragm 10 would require a copper or copper-plated compression ring and, if made of harder copper, would have limited movement and output due to its connection to the stiff short tube of the stethoscope body. The diaphragm 12 would be ineffective due to the non-copper...

Abstract

In a first embodiment, a stethoscope with a body; a diaphragm; and an integral annular axially compliant suspension is disclosed. The annular axially compliant suspension fits around the diaphragm andinside an inner perimeter of the body. Optionally, a reticulated foam pressure pad with an annular suspension is sealed on the interior or outer diameter of the body and the diaphragm is a very thinfoil, preferably made from copper, in order to provide antimicrobial properties. In a second embodiment, a stethoscope with a body and a diaphragm has a flexible enclosure containing an incompressibleliquid suspended in the stethoscope body is disclosed. A reticulated foam pressure pad with an annular suspension is sealed on the interior or outer diameter of the body. Optionally, the diaphragm has a cap over a top end of the suspended flexible enclosure, preferably made from copper in order to provide antimicrobial properties.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Application No. 62 / 570,302, filed October 10, 2017, and U.S. Provisional Application No. 62 / 645,553, filed March 20, 2018. The entire contents of the aforementioned applications are hereby incorporated by reference as if fully set forth herein. Background technique [0003] As a diagnostic means, a stethoscope is used to amplify sounds originating from the body emanating from the heart, lungs, stomach, etc. of a human or animal. Using a stethoscope, the listener can hear normal and abnormal airway, heart, pleural, arterial, venous, uterine, fetal, and intestinal sounds. Most stethoscopes have the following parts: eartip, ear tube, catheter, earpiece, stem, chest piece, diaphragm, and bell. Sound from the body is passively amplified and transmitted to the air volume via the bell or diaphragm. Diaphragm mechanisms are the preferred choice for most diagnostic applications. [0004] Diaphr...
