Abstract
Abstract A catheter placement unit adapted to advance a catheter in a sterile state comprising a catheter having a hub, a concentric needle and hub, a sheath, and a catheter container adapted to enclose a relatively long catheter and being adapted to advance the catheter from the container through the needle and sheath without exposing the catheter. The container in its preferred form is constructed of two halves which snap together to enclose the catheter, and snap apart to expose the catheter. The halves are relatively rotatable, and one half has two concentric walls, the outer wall providing frictional force on the catheter coiled therein, and causing the catheter to advance from the container when the said half is rotated relative to the remaining half.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
In the combination including a needle having a hub with a passage extending entirely through the needle hub; a catheter within the passageway, a portion of the catheter extending from said passage at said hub, said portion of the catheter housed within a container, said container constructed of at least two separable parts, one part constructed as a drum with a cylindrical segment and one closed end, another part constructed as a cover for the end of said cylindrical segment opposed said closed end, said other part having an outlet, said catheter wound on said One part and in frictional engagement with the inner surface of said cylindrical segment whereby rotation of said one part relative to said other part causes said catheter to move through said outlet in response to the frictional engagement between said catheter and the inner surface of said cylindrical segment.
Claim 2
Dependent Claim
145 words
In the combination including a needle having a hub with a passage extending entirely through the needle hub; a catheter within the passageway, a portion of the catheter extending from said passage at said hub, said portion of the catheter housed within a container, said container constructed of at least two separable parts, one part constructed as a drum with a cylindrical segment and one closed end, another part constructed as a cover for the end of said cylindrical segment opposed said closed end, said other part having an outlet, said catheter wound on said One part and in frictional engagement with the inner surface of said cylindrical segment whereby rotation of said one part relative to said other part causes said catheter to move through said outlet in response to the frictional engagement between said catheter and the inner surface of said cylindrical segment.
Claim 3
Dependent Claim
36 words
The container of claim 1 wherein rotation of said one part relative to said other part results in greater relative movement between said catheter and said other part than between said catheter and said one part.
Claim 4
Dependent Claim
48 words
The container of claim 2 wherein there is substantially no relative movement between said catheter and said one part upon relative movement between said one and said other parts comprises a drum which also serves as said first half and which is rotatably connected to said second half.
Claim 5
Dependent Claim
16 words
The container of claim 1 wherein said outlet is in direct communication with a needle hub.
Claim 6
Dependent Claim
22 words
The container of claim 1 wherein the catheter is provided with a wire stylet enclosed concentrically therein to render the catheter manipulatable.
Claim 7
Dependent Claim
24 words
The container of claim 1 wherein said outlet has means to free the catheter upon separation of said one part from said other part.
Claim 8
Dependent Claim
18 words
The container of claim 6 wherein said outlet is a tubular member connected tangentially to said other part.
Claim 9
Dependent Claim
23 words
The container of claim 6 wherein the means to free the catheter comprises an outlet having a diameter sufficient to pass the catheter.
Claim 10
Dependent Claim
39 words
The container of claim 6 wherein the means to free the catheter comprises an outlet having two halves adapted to be longitudinally separated to expose an axial slot of sufficient size to pass the catheter radially out said slot.
