Abstract
Abstract A sterile handle cover is disclosed for covering a lamp handle of a surgical lamp to provide a sterile surface for adjustment of the lamp by an operator. The handle cover comprises a grip portion defined by a first and a second end. An end wall is integrally attached proximate the first end of the grip portion to form a hollow container open at the second end. A protector is connected to the second end of the grip portion and extends radially outwardly for protecting the hand of the operator from contacting portions of the surgical lamp proximate the lamp handle. A plurality of ribs are disposed in the grip portion for frictionally engaging the lamp handle of the surgical lamp to maintain the position of the handle cover thereon.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
187 words
A handle protector for covering a lamp handle of a surgical lamp to provide a sterile surface for an operator, comprising: a grip portion having a first and a second end; an end wall integrally attached to said first end of said grip portion to form a hollow container open at said second end; protector means connected to said second end of said grip portion and extending radially outwardly for protecting the hand of the operator from contacting portions of the lamp proximate the lamp handle; said protector means including a first and a second protector; said first protector having a proximal end and a distal end with said proximal end being connected to said grip portion by a first reduced integral wall thickness; said second protector being connected to said distal end of said first protector; said second protector being connected to said distal end of said first protector by a second integral reduced wall thickness connector means; and a plurality of rib means disposed longitudinally in said grip portion by a first reduced integral wall thickness for frictionally engaging the lamp handle of the lamp.
Claim 2
Dependent Claim
187 words
A handle protector for covering a lamp handle of a surgical lamp to provide a sterile surface for an operator, comprising: a grip portion having a first and a second end; an end wall integrally attached to said first end of said grip portion to form a hollow container open at said second end; protector means connected to said second end of said grip portion and extending radially outwardly for protecting the hand of the operator from contacting portions of the lamp proximate the lamp handle; said protector means including a first and a second protector; said first protector having a proximal end and a distal end with said proximal end being connected to said grip portion by a first reduced integral wall thickness; said second protector being connected to said distal end of said first protector; said second protector being connected to said distal end of said first protector by a second integral reduced wall thickness connector means; and a plurality of rib means disposed longitudinally in said grip portion by a first reduced integral wall thickness for frictionally engaging the lamp handle of the lamp.
Claim 3
Dependent Claim
29 words
A handle protector as set forth in claim 1, wherein said second connector means enables said second protector to be movable between a first and a second bistable position.
Claim 4
Dependent Claim
70 words
A handle protector as set forth in claim 1, wherein said second integral reduced wall thickness connector means enables said second protector to be disposed in one of two bistable positions; said first bistable position enabling said second protector to extend in a direction along the direction of said first protector; and said second bistable position enabling said second protector to extend at an angle relative to said first protector.
Claim 5
Dependent Claim
191 words
A handle protector for covering a lamp handle of a surgical lamp to provide a sterile surface for an operator, comprising: a grip portion having a first and a second end; an end wall unitarily attached to said first end of said grip portion to form a hollow container open at said second end; protector means unitarily connected to said second end of said grip portion and extending radially outwardly for protecting the hand of the operator from contacting portions of the lamp proximate the lamp handle; said protector means including a first and a second protector; said first protector having a proximal end and a distal end with said proximal end being connected to said grip portion by a first integral wall thickness. said second protector being connected to said distal end of said first protector; said second protector being connected to said distal end of said first protector by a second integral reduced wall thickness connector means; and a plurality of rib means integrally molded to an interior surface of said grip portion and disposed longitudinally in said grip portion for frictionally engaging the lamp handle of the lamp.
Claim 6
Dependent Claim
191 words
A handle protector for covering a lamp handle of a surgical lamp to provide a sterile surface for an operator, comprising: a grip portion having a first and a second end; an end wall unitarily attached to said first end of said grip portion to form a hollow container open at said second end; protector means unitarily connected to said second end of said grip portion and extending radially outwardly for protecting the hand of the operator from contacting portions of the lamp proximate the lamp handle; said protector means including a first and a second protector; said first protector having a proximal end and a distal end with said proximal end being connected to said grip portion by a first integral wall thickness. said second protector being connected to said distal end of said first protector; said second protector being connected to said distal end of said first protector by a second integral reduced wall thickness connector means; and a plurality of rib means integrally molded to an interior surface of said grip portion and disposed longitudinally in said grip portion for frictionally engaging the lamp handle of the lamp.
Claim 7
Dependent Claim
29 words
A handle protector as set forth in claim 4, wherein said second connector means enables said second protector to be movable between a first and a second bistable position.
Claim 8
Dependent Claim
70 words
A handle protector as set forth in claim 4, wherein said second integral reduced wall thickness connector means enables said second protector to be disposed in one of two bistable positions; said first bistable position enabling said second protector to extend in a direction along the direction of said first protector; and said second bistable position enabling said second protector to extend at an angle relative to said first protector.
