Abstract
Abstract An intravenous catheter placement system in which a puncture needle and insertion catheter are disposed in guide passages formed in an easily handled blade-like body member. The body member is provided with guide track means cooperable with the needle in a manner to permit complete withdrawal and disposal of the needle after venipuncture to leave only the pliable insertion catheter remaining in the patient's vein. The needle may be either slotted to allow insertion of the catheter within the needle or provided with a pliable external sheath insertable with the needle and remaining after needle withdrawal to guide a small diameter insertion catheter for threading into the punctured vein. A catheter clamping means is provided to releasably retain the catheter against longitudinal movement in the body member which may be fixed to the exterior of the patient's body by a strap connected to the body or by taping.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
95 words
Catheter placement apparatus comprising: a body member with front and rear ends having a linear guiding passage extending longitudinally therein and a smoothly curved guiding passage merging with said linear guiding passage within said body member and opening through the rear end of said body member in essentially parallel relationship to said linear guiding passage; a venipuncture needle slidable received in said linear guiding passage, said needle having a puncture point at one end projecting from said body member at the front end and a hub block fixed at the opposite end of said needle;
Claim 2
Dependent Claim
95 words
Catheter placement apparatus comprising: a body member with front and rear ends having a linear guiding passage extending longitudinally therein and a smoothly curved guiding passage merging with said linear guiding passage within said body member and opening through the rear end of said body member in essentially parallel relationship to said linear guiding passage; a venipuncture needle slidable received in said linear guiding passage, said needle having a puncture point at one end projecting from said body member at the front end and a hub block fixed at the opposite end of said needle;
Claim 3
Dependent Claim
24 words
an insertion catheter positioned in said curved guiding passage and being normally slidable through said curved guiding passage and into said linear guiding passage.
Claim 4
Dependent Claim
24 words
an insertion catheter positioned in said curved guiding passage and being normally slidable through said curved guiding passage and into said linear guiding passage.
Claim 5
Dependent Claim
58 words
The apparatus recited in claim 1, wherein said needle is formed with a slot extending from said puncture point to an opening established as a terminal enlargement in said slot, said opening being initially positioned at the merger of said linear and curved guiding passages, said catheter extending through said opening and within said needle along said slot.
Claim 6
Dependent Claim
51 words
The apparatus recited in claim 1, wherein said needle is a closed tube from said puncture point to said hub block and including a pliable sheath extending from said body member toward said puncture point on the exterior of said needle and concentric therewith, said sheath being insertable with said needle.
Claim 7
Dependent Claim
27 words
The apparatus recited in claim 3, including an elastomeric seal to close the end of said passageway adjacent to said hub block upon withdrawal of said needle.
Claim 8
Dependent Claim
39 words
The apparatus recited in claim 4, wherein said hub block is formed of a transparent material and with a chamber at the end of said needle extending within said hub block to provide a flashback indication of venipuncture completion.
Claim 9
Dependent Claim
29 words
The apparatus recited in claim 3, further comprising a gasket in said curved guiding passage, said catheter extending through said gasket and being slidable with respect to said gasket.
Claim 10
Dependent Claim
16 words
The apparatus recited in claim 6, wherein the material of said gasket comprises closed cell foam.
Claim 11
Dependent Claim
41 words
The apparatus recited in claim 1 wherein said body member has a flat blade-like shape, the apparatus further comprising a fastening strap connected to said body member for attaching said body member inmovably to a surface to which venipuncture is made.
Claim 12
Dependent Claim
138 words
Apparatus for inserting a catheter comprising: a rigid body member having front and rear ends; a linear guiding passage extending through said body member for receiving a hollow needle; a curved guiding passage formed in said body member, said curved guiding passage merging with said linear guiding passage within said body member and extending from the rear end thereof in an essentially parallel spaced relation with respect to said linear passage; releasable catheter clamping means supported by said body member at the rear end thereof about said curved guiding passage to lock a catheter in said curved passageway against lonigitudinal movement with respect to said body member; and means defining a needle tracking guideway in said body member by which the linear and angular orientation of a hollow needle may be fixed with relation to said body member.
Claim 13
Dependent Claim
138 words
Apparatus for inserting a catheter comprising: a rigid body member having front and rear ends; a linear guiding passage extending through said body member for receiving a hollow needle; a curved guiding passage formed in said body member, said curved guiding passage merging with said linear guiding passage within said body member and extending from the rear end thereof in an essentially parallel spaced relation with respect to said linear passage; releasable catheter clamping means supported by said body member at the rear end thereof about said curved guiding passage to lock a catheter in said curved passageway against lonigitudinal movement with respect to said body member; and means defining a needle tracking guideway in said body member by which the linear and angular orientation of a hollow needle may be fixed with relation to said body member.
Claim 14
Dependent Claim
67 words
The apparatus recited in claim 9, wherein said releasable clamping means comprises boss means at the rear end of said body having external lugs and internal tapered surface concentric with said curved guiding passage, and an internally threaded clamp engageable with said lugs and having externally tapered flexible jaws movable by said internal tapered surface into clamping engagement with a catheter positioned within said curved guiding passage.
Claim 15
Dependent Claim
22 words
The apparatus recited in claim 10, wherein said clamp supports a sterile envelope to enclose a catheter extending within said curved passageway.
Claim 16
Dependent Claim
178 words
Catheter placement apparatus comprising: a body member with front and rear ends having a linear guiding passage extending longitudinally therein and a smoothly curved guiding passage merging with said linear guiding passage within said body member and opening through the rear end of said body member in essentially parallel relation to said linear guiding passage; a venipuncture needle slidably received in said linear guiding passage, said needle having a puncture point at one end projecting from said body member at the front end and a hub block fixed at the opposite end of said needle; means defining a hub block track in said body member to accommodate linear movement of said hub block towards said rear end of said body member for withdrawal of said needle from said body member in constant angular orientation; an insertion catheter positioned in said curved guiding passage; and means to clamp said catheter releasably against longitudinal movement in said body member, said catheter being slidable through said curved guiding passage and said linear guiding passage except when clamped by said clamping means.
Claim 17
Dependent Claim
