Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
180 words
An intravenous catheter assembly comprising an elongated catheter; a hollow needle movably disposed in said catheter; and a flexible wing assembly including an intermediate housing having an axial bore therethrough, said housing having first recess means on one side thereof contiguous with said bore and second recess means on a second side thereof opposite said first side and contiguous with said bore, and first and second flexible wings extending radially from said housing, said first and second wings being disposed on opposite sides of said housing between said first and second recesses and being movable from a normal position to a hold position to deform said housing; said catheter being removably received in said axial bore of sAid housing such that said flexible wing assembly is movable along said catheter to a plurality of axially displaced positions when said first and second wings are in said normal position and said catheter being gripped by said housing at any of said axially displaced positions when said housing is deformed by said first and second wings being moved to said hold position.
Claim 2
Dependent Claim
180 words
An intravenous catheter assembly comprising an elongated catheter; a hollow needle movably disposed in said catheter; and a flexible wing assembly including an intermediate housing having an axial bore therethrough, said housing having first recess means on one side thereof contiguous with said bore and second recess means on a second side thereof opposite said first side and contiguous with said bore, and first and second flexible wings extending radially from said housing, said first and second wings being disposed on opposite sides of said housing between said first and second recesses and being movable from a normal position to a hold position to deform said housing; said catheter being removably received in said axial bore of sAid housing such that said flexible wing assembly is movable along said catheter to a plurality of axially displaced positions when said first and second wings are in said normal position and said catheter being gripped by said housing at any of said axially displaced positions when said housing is deformed by said first and second wings being moved to said hold position.
Claim 3
Dependent Claim
60 words
The invention as recited in claim 1 wherein said housing has first and second ends, said first recess means includes a first recess centrally disposed between said first and second ends in communication with said axial bore and said second recess means includes second and third recesses disposed adjacent said first and second ends, respectively, in communication with said bore.
Claim 4
Dependent Claim
38 words
The invention as recited in claim 1 wherein said catheter carries a hub on one end thereof and a tubular guard surrounds said catheter and has a U-shaped section at one end thereof removably secured to said hub.
Claim 5
Dependent Claim
26 words
The invention as recited in claim 3 wherein a hub is provided for said needle, said needle including a removable air vent sealing said needle hub.
Claim 6
Dependent Claim
34 words
The invention as recited in claim 1 wherein said first and second wings have adhesive means secured to the undersides thereof whereby said first and second wings may be secured in said hold position.
Claim 7
Dependent Claim
141 words
An intravenous catheter assembly comprising an elongated catheter; a hollow needle movably disposed in said catheter; a gripping assembly including a housing having an axial bore therethrough and first and second wings extending from opposite sides of said housing, said catheter being removably received in said axial bore; and said housing having a plurality of recess means therein contiguous with said axial bore to permit deformation of said housing when said first and second wings are moved, said first and second wings having a normal position and being movable in a first direction from said normal position to a first hold position to deform said housing and grip said catheter and in a second direction from said normal position to a second hold position to deform said housing and grip said catheter, said second direction being opposite to said first direction.
Claim 8
Dependent Claim
141 words
An intravenous catheter assembly comprising an elongated catheter; a hollow needle movably disposed in said catheter; a gripping assembly including a housing having an axial bore therethrough and first and second wings extending from opposite sides of said housing, said catheter being removably received in said axial bore; and said housing having a plurality of recess means therein contiguous with said axial bore to permit deformation of said housing when said first and second wings are moved, said first and second wings having a normal position and being movable in a first direction from said normal position to a first hold position to deform said housing and grip said catheter and in a second direction from said normal position to a second hold position to deform said housing and grip said catheter, said second direction being opposite to said first direction.
Claim 9
Dependent Claim
39 words
The invention as recited in claim 6 wherein said first and second wings have adhesive means secured to the undersides thereof whereby said first and second wings may be secured in either of said first or second hold positions.
