Abstract
Abstract A device for inserting a catheter into a mammalian body, comprising a housing member for storing a flexible catheter, a hollow needle connected to the catheter and supported on the housing member so as to form an extension of a side of the housing member, and at least one driven roller within said housing member for engaging and moving the catheter through the needle. An end of a removable shield for the needle is inserted in an opening in the housing member for rotating the driven roller.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
206 words
A device for inserting a catheter into a mammalian body, comprising: a housing member for antiseptic storage of said catheter, a hollow needle supported on said housing member so as to form an extension of a side thereof, said needle being openable along its length for removal of said catheter, 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, drive means interiorly adjacent said housing 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; and 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
Independent Claim
206 words
A device for inserting a catheter into a mammalian body, comprising: a housing member for antiseptic storage of said catheter, a hollow needle supported on said housing member so as to form an extension of a side thereof, said needle being openable along its length for removal of said catheter, 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, drive means interiorly adjacent said housing 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; and 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
44 words
The device of claim 1 wherein one of said rollers is an idler roller and the other of said rollers is a driven roller, said rollers being positioned in said housing such that said catheter is receivable between said rollers to form said nip.
Claim 5
Dependent Claim
37 words
The device of claim 1 wherein each said roller has a said second portion, and wherein said drive means includes a pair of gears in meshing engagement, said rollers being connected to said gears for rotation therewith.
Claim 6
Dependent Claim
14 words
The device of claim 4 further including means for rotating one of said gears.
Claim 7
Dependent Claim
32 words
The device of claim 3 wherein said housing member has a base member and a removable cover, said cover having an opening therein adapted to receive means for actuating said driven roller.
Claim 8
Dependent Claim
59 words
The device of claim 6 wherein said driven roller has a recess therein adjacent said opening, and said means for actuating said driven roller comprises a removable shield for said needle, said shield having a tip complementary in shape to the shape of said recess, whereby said shield is adapted for a press-fit into said recess through said opening.
Claim 9
Dependent Claim
39 words
The device of claim 1 wherein said housing member has a base member and a removable cover, wherein said needle has a clamping member thereon, and wherein said base member has an extension adapted to receive said clamping member.
Claim 10
Dependent Claim
59 words
The device of claim 8 wherein said needle is slotted and scored parallel along its length to thereby define two halves of said needle, and wherein said clamping member comprises a pair of wing-like members which are unitary one with each of said halves, whereby said needle may be opened into said halves for removal of said catheter therefrom.
Claim 11
Dependent Claim
28 words
The device of claim 9 including a removable shield for said needle, and wherein said extension of said base member includes a portion adapted to support said shield.
Claim 12
Dependent Claim
47 words
The device of claim 8 wherein said housing is adapted to hold a member which is adapted for epidermal fixing of the distal end of a catheter to a patient, said member being removable from said housing member together with said catheter upon removal of said cover.
Claim 13
Dependent Claim
14 words
The device of claim 4 wherein said second portions are defined by said gears.
Claim 14
Dependent Claim
53 words
The device of claim 6 including a pair of projections mounted on said cover and positioned to extend into said base member, the lengths of said projections being such as to align said catheter between the ends of said projections and said base member so as to guide said catheter to said needle.
Claim 15
Independent Claim
288 words
A device for inserting a catheter into a mammalian body, comprising: a housing member for antiseptic storage of said catheter, a hollow needle supported on said housing member so as to form an extension of a side thereof, said needle being openable along its length for removal of said catheter, said housing member having a base member and a removable cover therefor and defining a passage for antiseptically moving a flexible catheter to said hollow needle, said passage being adjacent the entrance to said hollow needle, said housing member further defining a first chamber adapted to receive said flexible catheter and a second chamber adapted to antiseptically enclose said pair of rollers, and drive means 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 to form a nip for said catheter between the rims of said rollers, said drive means further including a pair of gears in meshing engagement, said rollers being connected to said gEars for rotation therewith, said gears being defined by a second portion on each said roller of diameter greater than the diameter of the portion of the rollers that engage and move said catheter, said second portions being positioned to align said catheter between said second portions and the base member of said housing, whereby said catheter is guided smoothly to said needle; said device further including a pair of projections mounted on said cover and positioned to extend into said base member, the lengths of said projections being such as to align said catheter between the ends of said projections and said base member so as to guide said catheter to said needle.
Claim 16
