Abstract

Abstract A cover for a pre-cordial stethoscope provides protection for the stethoscope and reduces external noise contamination. The cover fits closely on the stethoscope body and includes a slot for receiving a tubular fitting which extends from the stethoscope body to transmit the monitored sounds. A shell presenting an internal vacuum chamber may be interposed between the cover and stethoscope body for enhanced noise suppression. Different embodiments of the cover are provided for adult and infant pre-cordial stethoscopes.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 122 words
A protective cover for a pre-cordial stethoscope having a cylindrical body presenting a cavity open at a bottom of a body and a tubular fitting on the body communicating with the cavity, said cover comprising: a discoidal top having a size to span the stethoscope body and having a circular outer edge; a generally cylindrical side wall extending from the edge of said discoidal top, said side wall terminating in a circular lower edge and being cooperable with said top to substantially cover the stethoscope body when applied thereto; and said top and wall being formed from a relatively soft material and the cavity in the stethoscope body remaining open at the bottom when the cover is applied to the stethoscope body.
Claim 2
Dependent Claim 122 words
A protective cover for a pre-cordial stethoscope having a cylindrical body presenting a cavity open at a bottom of a body and a tubular fitting on the body communicating with the cavity, said cover comprising: a discoidal top having a size to span the stethoscope body and having a circular outer edge; a generally cylindrical side wall extending from the edge of said discoidal top, said side wall terminating in a circular lower edge and being cooperable with said top to substantially cover the stethoscope body when applied thereto; and said top and wall being formed from a relatively soft material and the cavity in the stethoscope body remaining open at the bottom when the cover is applied to the stethoscope body.
Claim 3
Dependent Claim 40 words
The cover of claim 1, including a slot in said side wall extending from the lower edge thereof at a location to accommodate extension of the tubular fitting through said slot when the cover is applied to the stethoscope body.
Claim 4
Dependent Claim 17 words
The cover of claim 1, including a rigid disk secured to said discoidal top to stiffen same.
Claim 5
Dependent Claim 40 words
The cover of claim 3, including a slot in said side wall extending from the lower edge thereof at a location to accommodate extension of the tubular fitting through said slot when the cover is applied to the stethoscope body.
Claim 6
Dependent Claim 19 words
The cover of claim 1, including means for providing a vacuum chamber between the cover and the stethoscope body.
Claim 7
Dependent Claim 56 words
The cover of claim 1, including a hollow shell having a discoidal top between said discoidal top of the cover an the stethoscope body and a cylindrical side wall between the side wall of the cover and the stethoscope body, said shell presenting a vacuum chamber within the top and side wall thereof for suppressing noise.
Claim 8
Dependent Claim 41 words
The cover of claim 6, including mating slots in said side walls of the cover and shell at a location to accommodate extension of the tubular fitting through the slots when the cover and shell are applied to the stethoscope body.
Claim 9
Dependent Claim 133 words
In combination with a pre-cordial stethoscope having a cylindrical body presenting a cavity open at a bottom of the body and a tubular fitting projecting sidewardly from the body and communicating with the cavity, a protective cover comprising: a discoidal top spanning the stethoscope body and having a circular outer edge; a generally cylindrical side wall extending from said edge of the top and encircling the stethoscope body but leaving the cavity open at the bottom of the body, said side wall and top being formed integrally from a relatively soft material and said side wall terminating in a circular lower edge extending around the stethoscope body; and a slot in said side wall extending from the lower edge thereof at a location to receive the tubular fitting in extension through the slot.
Claim 10
Dependent Claim 133 words
In combination with a pre-cordial stethoscope having a cylindrical body presenting a cavity open at a bottom of the body and a tubular fitting projecting sidewardly from the body and communicating with the cavity, a protective cover comprising: a discoidal top spanning the stethoscope body and having a circular outer edge; a generally cylindrical side wall extending from said edge of the top and encircling the stethoscope body but leaving the cavity open at the bottom of the body, said side wall and top being formed integrally from a relatively soft material and said side wall terminating in a circular lower edge extending around the stethoscope body; and a slot in said side wall extending from the lower edge thereof at a location to receive the tubular fitting in extension through the slot.
Claim 11
Dependent Claim 17 words
The cover of claim 8, including a rigid disk secured to said discoidal top to stiffen same.
Claim 12
Dependent Claim 19 words
The cover of claim 8, including means for providing a vacuum chamber between the cover and the stethoscope body.
Claim 13
Dependent Claim 56 words
The cover of claim 8, including a hollow shell having a discoidal top between said discoidal top of the cover and the stethoscope body and a cylindrical side wall between the side wall of the cover and the stethoscope body, said shell presenting a vacuum chamber within the top and side wall thereof for supporting noise.
Claim 14
Dependent Claim 41 words
The cover of claim 11, including a slot in the side wall of said shell at a location to register with the slot in the side wall of the cover and to receive the tubular fitting in extension through both slots.
Claim 15
Dependent Claim 115 words
A protective cover for a pre-cordial infant stethoscope having a discoidal body with an open bottomed cavity therein and a laterally projecting tubular fitting communicating with the cavity, said cover comprising: a discoidal top having a size to span the stethoscope body and having a circular outer edge; an annular lip on the outer edge of said discoidal top projecting in a direction to encircle the stethoscope body when applied thereto, said top and lip being formed integrally from a relatively soft material and said lip terminating in an edge located above the tubular fitting to prevent the cover from interfering with the fitting; and means for adhesively securing said top to the stethoscope body.
