Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
197 words
A hand-holdable device for antiseptically inserting a catheter into a vessel a predetermined distance, said device comprising: a housing member for antiseptic storage of said catheter, said housing member having a first side, a hollow needle supported in said housing member, said housing member defining a passage for antiseptically moving a flexible catheter to said hollow needle, said passage being adjacent the entrance to said hollow needle, and drive means interiorly adjacent said first side for engaging and moving said catheter through said passage and said needle; said drive means comprising a pair of rollers positioned to rotate on parallel, spaced apart, axes and to form a nip for said catheter between the rims of said rollers, at least one of said rollers having a second portion opposite said housing side of diameter greater than the diameter of the portion of the roller that engages and moves said catheter; wherein a catheter receiving space is defined by said nip, said second portion and said housing side aligned with said passage and said needle, whereby said catheter is prevented from binding therein, said catheter is maintained adjacent said nip and said catheter is guided smoothly to said needle.
Claim 2
Dependent Claim
197 words
A hand-holdable device for antiseptically inserting a catheter into a vessel a predetermined distance, said device comprising: a housing member for antiseptic storage of said catheter, said housing member having a first side, a hollow needle supported in said housing member, said housing member defining a passage for antiseptically moving a flexible catheter to said hollow needle, said passage being adjacent the entrance to said hollow needle, and drive means interiorly adjacent said first side for engaging and moving said catheter through said passage and said needle; said drive means comprising a pair of rollers positioned to rotate on parallel, spaced apart, axes and to form a nip for said catheter between the rims of said rollers, at least one of said rollers having a second portion opposite said housing side of diameter greater than the diameter of the portion of the roller that engages and moves said catheter; wherein a catheter receiving space is defined by said nip, said second portion and said housing side aligned with said passage and said needle, whereby said catheter is prevented from binding therein, said catheter is maintained adjacent said nip and said catheter is guided smoothly to said needle.
Claim 3
Dependent Claim
31 words
The device of claim 1 wherein said housing member defines a first chamber adapted to receive said flexible catheter and a second chamber adapted to antiseptically enclose said pair of rollers.
Claim 4
Dependent Claim
42 words
The device of claim 1 wherein each of said rollers has a second portion of diameter greater than the portions of the rollers which engage and move said catheter, said second portions being spaced apart to permit removal of said catheter therebetween.
Claim 5
Dependent Claim
27 words
The device of claim 1 further including a pair of gears in meshing engagement, said rollers being attached one to each of said gears for rotation therewith.
Claim 6
Dependent Claim

The device of claim 1 wherein said needle has a slot defined along the length thereof to allow removal of a catheter therefrom.
Claim 10
Dependent Claim
44 words
The device of claim 1 wherein said needle is provided with an enlarged end portion, said housing member defines a chamber adapted to receive said enlarged end portion, said device having a slot defined in said needle and end portion along the length thereof.
Claim 11
Dependent Claim
26 words
The device of claim 1 wherein said housing member has a slot extending along the length thereof to permit removal of a catheter in said housing.
Claim 12
Dependent Claim
