Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
202 words
A removable blade cover system to be used with a speculum of the type including a lower blade and an upper blade, each blade having a concave blade surface and convex blade surface, said concave blade surfaces being in opposing relationship facing each other that can be separated or opened to provide a concave walled viewing channel therebetween for visual examination and treatment of a patient, the blade cover system characterized by: a blade cover having opposite site edges and a flexible one-piece integrally formed elastic hollow sleeve with an open end and an opposite closed end constructed to be placed in covering protective relation over a speculum blade with a concave exterior surface and convex exterior surface closely conforming to substantially the entire length and sides of the respective blade surfaces; a smoke tube disposed along the concave exterior surface of the blade cover with one end exposed to an exterior of said blade cover to retrieve smoke from about said blade cover and another opposite end operably connectable to a vacuum pump; and said smoke tube being integrally formed with and unitary with the concave surface of the blade cover and formed from the same material as the blade cover.
Claim 2

A removable blade cover system to be used with a speculum of the type including a lower blade and an upper blade, each blade having a concave blade surface and convex blade surface, said concave blade surfaces being in opposing relationship facing each other that can be separated or opened to provide a concave walled viewing channel therebetween for visual examination and treatment of a patient, the blade cover system characterized by: a blade cover having opposite site edges and a flexible one-piece integrally formed elastic hollow sleeve with an open end and an opposite closed end constructed to be placed in covering protective relation over a speculum blade with a concave exterior surface and convex exterior surface closely conforming to substantially the entire length and sides of the respective blade surfaces; a smoke tube disposed along the concave exterior surface of the blade cover with one end exposed to an exterior of said blade cover to retrieve smoke from about said blade cover and another opposite end operably connectable to a vacuum pump; and said smoke tube being integrally formed with and unitary with the concave surface of the blade cover and formed from the same material as the blade cover.
Claim 3
Dependent Claim
224 words
A removable blade cover system to be used with a speculum of the type including a lower blade and an upper blade, each blade having a concave blade surface and convex blade surface, said concave blade surfaces being in opposing relationship facing each other that can be separated or opened to provide a concave walled viewing channel therebetween for visual examination and treatment of a patient, the blade cover system characterized by: a blade cover having opposite site edges and a flexible one-piece integrally formed elastic hollow sleeve with an open end and an opposite closed end constructed to be placed in covering protective relation over a speculum blade with a concave exterior surface and convex exterior surface closely conforming to substantially the entire length and sides of the respective blade surfaces; a smoke tube disposed along the concave exterior surface of the blade cover with one end exposed to an exterior of said blade cover to retrieve smoke from about said blade cover and another opposite end operably connectable to a vacuum pump; and a tube mount being disposed on and integrally formed simultaneously with the concave surface of the blade cover, the tube mount extending from said concave exterior surface and having a cavity formed therethrough; and said smoke tube being insertably and removably disposed within the cavity of the tube mount.
Claim 4
Dependent Claim
224 words
A removable blade cover system to be used with a speculum of the type including a lower blade and an upper blade, each blade having a concave blade surface and convex blade surface, said concave blade surfaces being in opposing relationship facing each other that can be separated or opened to provide a concave walled viewing channel therebetween for visual examination and treatment of a patient, the blade cover system characterized by: a blade cover having opposite site edges and a flexible one-piece integrally formed elastic hollow sleeve with an open end and an opposite closed end constructed to be placed in covering protective relation over a speculum blade with a concave exterior surface and convex exterior surface closely conforming to substantially the entire length and sides of the respective blade surfaces; a smoke tube disposed along the concave exterior surface of the blade cover with one end exposed to an exterior of said blade cover to retrieve smoke from about said blade cover and another opposite end operably connectable to a vacuum pump; and a tube mount being disposed on and integrally formed simultaneously with the concave surface of the blade cover, the tube mount extending from said concave exterior surface and having a cavity formed therethrough; and said smoke tube being insertably and removably disposed within the cavity of the tube mount.
Claim 5
Dependent Claim
67 words
A removable blade cover as defined in claim 2 further characterized by: said tube mount being elongated in shape with at least one wall defining an elongated substantially cylindrical cavity passing therethrough; said cavity having one end being sized to receive a tube therethrough with the at least one wall of the tube mount frictionally engaging said tube in a normally fixed position against unwanted accidental motion.
Claim 6
Dependent Claim
21 words
A removable blade cover as defined in claim 2 further characterized by: said smoke tube being a flexible elastic hollow tube.
Claim 7
Dependent Claim
101 words
A removable elastomeric speculum blade cover for removable placement over a blade of a speculum, said blade cover characterized by: a one piece integrally formed sleeve with an open end and an opposite closed end and with a concave exterior surface; a smoke tube disposed along the concave exterior surface, said tube having opposite ends exposed to ambient exterior about said sleeve, one of said ends being operably connectable to a vacuum pump; and said smoke tube being integrally formed with and unitary with the concave surface of the blade cover and formed from the same material as the blade cover.
Claim 8
Dependent Claim
101 words
A removable elastomeric speculum blade cover for removable placement over a blade of a speculum, said blade cover characterized by: a one piece integrally formed sleeve with an open end and an opposite closed end and with a concave exterior surface; a smoke tube disposed along the concave exterior surface, said tube having opposite ends exposed to ambient exterior about said sleeve, one of said ends being operably connectable to a vacuum pump; and said smoke tube being integrally formed with and unitary with the concave surface of the blade cover and formed from the same material as the blade cover.
Claim 9
Dependent Claim
21 words
