Abstract
Abstract A catheter hub including a housing having a connection end defining a first fluid passageway and a catheter end defining a second fluid passageway. The housing includes a plurality of hub walls arranged in a geometric configuration. The hub walls define a valve chamber. The catheter hub further includes a valve positioned in the valve chamber for controlling fluid flow through the chamber between the first and second fluid passageways. The catheter hub further includes an actuator for actuating the valve. The catheter hub regulates fluid flow between the first and second fluid passageways.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
112 words
A catheter hub comprising: a housing having a connection end defining a first fluid passageway and a catheter end defining a second fluid passageway, said housing including a plurality of hub walls, with one hub wall forming a bottom of the housing and said bottom being wider than any other said hub wall, said plurality of hub walls defining a valve chamber; a valve positioned in said valve chamber for controlling fluid flow in both directions through said chamber between said first and second fluid passageways wherein the valve is a solid member having a diameter larger than length to form a plug-type valve, and an actuator means for actuating said valve.
Claim 2
Dependent Claim
112 words
A catheter hub comprising: a housing having a connection end defining a first fluid passageway and a catheter end defining a second fluid passageway, said housing including a plurality of hub walls, with one hub wall forming a bottom of the housing and said bottom being wider than any other said hub wall, said plurality of hub walls defining a valve chamber; a valve positioned in said valve chamber for controlling fluid flow in both directions through said chamber between said first and second fluid passageways wherein the valve is a solid member having a diameter larger than length to form a plug-type valve, and an actuator means for actuating said valve.
Claim 3
Dependent Claim
17 words
The invention of claim 1, wherein said catheter end includes a catheter consisting of a polymeric material.
Claim 4
Dependent Claim
14 words
The invention of claim 1, wherein said connection end includes a plurality of threads.
Claim 5
Dependent Claim
17 words
The invention of claim 1, wherein said connection end defines an annular shoulder adjacent said valve chamber.
Claim 6
Dependent Claim
26 words
The invention of claim 1, wherein said housing includes a top and a bottom, at least one of said hub walls being planar at said bottom.
Claim 7
Dependent Claim
19 words
The invention of claim 1, wherein said housing includes a plurality of hub walls arranged in a polygonal configuration.
Claim 8
Dependent Claim
12 words
The invention of claim 6, wherein said polygonal configuration is a hexagon.
Claim 9
Dependent Claim
21 words
The invention of claim 1, wherein said housing includes a valve seat positioned in said valve chamber adjacent said catheter end.
Claim 10
Dependent Claim
29 words
The invention of claim 8, wherein said valve seat includes a plurality of fluid openings to allow for fluid flow between said valve chamber and said second fluid passageway.
Claim 11
Dependent Claim
22 words
The invention of claim 1, wherein said valve comprises resilient material, said valve extending substantially between said first and second fluid passageways.
Claim 12
Dependent Claim
68 words
The invention of claim 4, wherein said valve comprises resilient material having a substantially cylindrical configuration, said valve having an actuator end and a housing end, said actuator end being engaged with said annular shoulder, whereby actuation of said actuator means causes said actuator end to become disengaged from said shoulder to allow fluid flow through said first fluid passageway, said valve chamber and said second fluid passageway.
Claim 13
Dependent Claim
17 words
The invention of claim 11, wherein said actuator end includes an annular seal adjacent said annular shoulder.
Claim 14
Dependent Claim
34 words
The invention of claim 11, wherein said actuator end includes an actuator projection received by said first fluid passageway, a retaining flange positioned on said actuator projections, said actuator means engaging said retaining flange.
Claim 15
Dependent Claim
13 words
The invention of claim 1, wherein said valve includes an integral annular seal.
Claim 16
Dependent Claim
31 words
The invention of claim 1, further including a valve plate and at least one spring positioned within said valve chamber, wherein at least one spring is attached to the valve plate.
Claim 17
Dependent Claim
25 words
The invention of claim 14, wherein the valve further includes an actuator projection having a retaining flange, wherein the actuator means engages the retaining flange.
Claim 18
Dependent Claim
13 words
The invention of claim 10, wherein the resilient material defines an hourglass shape.
Claim 19
Dependent Claim
30 words
The invention of claim 1, wherein the valve is frusto-conical and further includes a spring wall, and the valve chamber further includes a spring positioned adjacent to said spring wall.
Claim 20
Dependent Claim
61 words
The invention of claim 1 wherein the valve is frusto-conical and further includes a face interaction portion and a plurality of opposed support legs having a center baffle position and an annular flange portion, wherein each support leg defines a leg opening, and wherein the valve further includes a center baffle positioned adjacent said leg openings in the center baffle position.
