Catheter retainer

Claim 2

A catheter retainer comprising a pad of adhesive dressing material having one surface for contacting the skin of a wearer and a central opening, a coupling member having a flange permanently affixed to the other surface of said adhesive pad around said opening, said coupling member also including an upstanding rim and an resilient flexible skirt projecting inwardly from the periphery of said rim, and a catheter retainer insert dimensioned to fit within said coupling member rim and be held in place by said resilient skirt, said catheter retainer comprising a member of synthetic plastics material having a central hole wholly or partly defined by a pair of resilient catheter-gripping jaws, and a resilient catch member for holding the jaws in their relatively closed position.

Claim 3

A catheter retainer according to claim 1 in which the insert carries pegs to enable finger manipulation of the jaws.

Claim 4

A catheter retainer according to claim 1 in which said coupling member and said catheter retainer insert are of circular configuration.

Claim 5

A catheter retainer according to claim 1 in which said adhesive pad has a film of polymeric material on the surface which does not contact the body and the flange of said coupling member is welded or adhesively affixed to said polymeric film.

Claim 6

A catheter retainer capable of holding catheters of varying external diameter in position, said retainer being formed from a single piece of plastics material and comprising a disc having a marginal rim portion and a central portion which includes an arcuate hole that merges with a catheter slot, a limb section, and a base pad, one end of said limb being connected to said base pad by an integral hinge thereby enabling said limb to oscillate about said hinge in the plane of the disc, the other end of said limb having a hook which cooperates with a series of notches on said base pad, said catheter slot positioned between opposing walls of said limb and said base pad with a series of catheter gripping jaws on these opposing limb and base pad walls.

Claim 7

A catheter retainer capable of holding catheters of varying external diameter in position, said retainer being formed from a single piece of plastics material and comprising a disc having a marginal rim portion and a central portion which includes an arcuate hole that merges with a catheter slot, a limb section, and a base pad, one end of said limb being connected to said base pad by an integral hinge thereby enabling said limb to oscillate about said hinge in the plane of the disc, the other end of said limb having a hook which cooperates with a series of notches on said base pad, said catheter slot positioned between opposing walls of said limb and said base pad with a series of catheter gripping jaws on these opposing limb and base pad walls.

Claim 8

The catheter retainer of claim 5 wherein said limb and said base pad have upstanding pegs which allow finger manipulation of said limb relative to said base pad.

Claim 9

A catheter retainer capable of holding catheters of varying external diameter in position, said retainer comprising an adhesive dressing one surface of which adheres the retainer to the skin, said dressing having a central opening, a coupling member having a flange permanently affixed to the other surface of said dressing around said central opening, said coupling member also having an upstanding rim and a resilient flexible skirt projecting inwardly from the periphery of said rim, and a catheter retainer insert formed from a single piece of plastics material comprising a disc having a marginal rim portion and a central portion, said marginal rim portion dimensioned to fit between said coupling member rim and said dressing and be held in place by said resilient skirt, said disc central portion including an arcuate hole that merges with a catheter slot, a limb section, and a base pad, one end of said limb being connected to said base pad by an integral hinge thereby enabling said limb to oscillate about said hinge in the plane of the disc, the other end of said limb having a hook which cooperates with a series of notches on said base pad, said catheter slot positioned between opposing walls of said limb and said base pad with a series of catheter gripping jaws on these opposing limb and base pad walls.

Claim 10

A catheter retainer capable of holding catheters of varying external diameter in position, said retainer comprising an adhesive dressing one surface of which adheres the retainer to the skin, said dressing having a central opening, a coupling member having a flange permanently affixed to the other surface of said dressing around said central opening, said coupling member also having an upstanding rim and a resilient flexible skirt projecting inwardly from the periphery of said rim, and a catheter retainer insert formed from a single piece of plastics material comprising a disc having a marginal rim portion and a central portion, said marginal rim portion dimensioned to fit between said coupling member rim and said dressing and be held in place by said resilient skirt, said disc central portion including an arcuate hole that merges with a catheter slot, a limb section, and a base pad, one end of said limb being connected to said base pad by an integral hinge thereby enabling said limb to oscillate about said hinge in the plane of the disc, the other end of said limb having a hook which cooperates with a series of notches on said base pad, said catheter slot positioned between opposing walls of said limb and said base pad with a series of catheter gripping jaws on these opposing limb and base pad walls.

Claim 11

The catheter retainer of claim 7 wherein said limb and said base pad having upstanding pegs which allow finger manipulation of said limb relative to said base pad.
