Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
73 words
An assembly for externally securing a catheter at or adjacent to an exit site on a body tissue comprising: a resilient member having a base for attachment to the body tissue and means for retaining the catheter, said retaining means comprising a resilient, radially extending support arm with an open longitudinal circular channel spaced from the base; and a detachably removable and adjustable clamp for uniformly tightening the catheter within the retaining means.
Claim 2
Dependent Claim
73 words
An assembly for externally securing a catheter at or adjacent to an exit site on a body tissue comprising: a resilient member having a base for attachment to the body tissue and means for retaining the catheter, said retaining means comprising a resilient, radially extending support arm with an open longitudinal circular channel spaced from the base; and a detachably removable and adjustable clamp for uniformly tightening the catheter within the retaining means.
Claim 3
Dependent Claim
22 words
The assembly of claim 1 further comprising an adhesive dressing for securing said resilient member at or adjacent to the exit site.
Claim 4
Dependent Claim
32 words
The assembly of claim 1 wherein said adjustable clamp includes two laterally movable arms with interlocking teeth for closing and locking said adjustable clamp and securing the catheter within said resilient member.
Claim 5
Dependent Claim
23 words
The assembly of claim 3 wherein said clamp, when closed, may be opened for removing the catheter by laterally displacing the interlocking teeth.
Claim 6
Dependent Claim
25 words
The assembly of claim 1 wherein the catheter has an outer diameter which is substantially the same as the inner diameter of said retaining means.
Claim 7
Dependent Claim
27 words
The assembly of claim 5 wherein said outer diameter of said catheter is greater than said inner diameter of said retaining means when said assembly is closed.
Claim 8
Dependent Claim
26 words
The assembly of claim 1 wherein said resilient member includes a plurality of openings for suturing said resilient member at or adjacent to the exit site.
Claim 9
Dependent Claim
21 words
The assembly of claim 1 wherein said resilient member is adjacently positioned about one to two inches from the exit site.
Claim 10
Independent Claim
95 words
A system for externally securing a catheter at or adjacent to an exit site on a body tissue comprising: a resilient member having retaining means with an inner diameter that is substantially the same as the outer diameter of the catheter; and a detachably removable and adjustable clamp for uniformly tightening the retaining means to grip the catheter without affecting the inner diameter of the catheter, said adjustable clamp having an inner diameter when closed corresponding with the outer diameter of said retaining means, said clamp being reversible to release the grip on the catheter.
Claim 11
Independent Claim
95 words
A system for externally securing a catheter at or adjacent to an exit site on a body tissue comprising: a resilient member having retaining means with an inner diameter that is substantially the same as the outer diameter of the catheter; and a detachably removable and adjustable clamp for uniformly tightening the retaining means to grip the catheter without affecting the inner diameter of the catheter, said adjustable clamp having an inner diameter when closed corresponding with the outer diameter of said retaining means, said clamp being reversible to release the grip on the catheter.
Claim 12
Dependent Claim
20 words
The system of claim 9 wherein said retaining means is a collar with a channel for concentrically circumscribing the catheter.
Claim 13
Dependent Claim
20 words
The system of claim 9 wherein said retaining means is a radially extending support arm with a longitudinal circular channel.
Claim 14
Dependent Claim
39 words
The system of claim 9 wherein said adjustable clamp includes two laterally movable arms with interlocking teeth for closing and locking said adjustable clamp and securing the catheter within said resilient member and for opening and releasing the catheter.
Claim 15
Dependent Claim
25 words
The system of claim 12 wherein said clamp, when closed, may be unlocked and opened for removing the catheter by laterally displacing the interlocking teeth.
Claim 16
Dependent Claim
76 words
An assembly for externally securing a catheter at or adjacent to an exit site on a body tissue comprising: a resilient member with an upstanding collar having a channel for receiving and concentrically circumscribing the catheter and a flange encircling the collar at its free end, said collar having a concave upper surface extending to the outer edge of the flange; and a detachably removable and adjustable clamp for uniformly tightening the catheter within said channel.
Claim 17
Dependent Claim
76 words
An assembly for externally securing a catheter at or adjacent to an exit site on a body tissue comprising: a resilient member with an upstanding collar having a channel for receiving and concentrically circumscribing the catheter and a flange encircling the collar at its free end, said collar having a concave upper surface extending to the outer edge of the flange; and a detachably removable and adjustable clamp for uniformly tightening the catheter within said channel.
Claim 18
Dependent Claim
70 words
An assembly for externally securing a catheter at or adjacent to an exit site on a body tissue comprising: a resilient member with means for retaining the catheter; and a detachably removable and adjustable locking clamp for gripping the catheter within said retaining means, the clamp having a closed position whereby when the clamp is closed the inner diameter of the catheter is unaffected, and for releasing the catheter therefrom.
Claim 19
Dependent Claim
70 words
An assembly for externally securing a catheter at or adjacent to an exit site on a body tissue comprising: a resilient member with means for retaining the catheter; and a detachably removable and adjustable locking clamp for gripping the catheter within said retaining means, the clamp having a closed position whereby when the clamp is closed the inner diameter of the catheter is unaffected, and for releasing the catheter therefrom.
Claim 20
Dependent Claim
20 words
The assembly of claim 15 wherein said retaining means is a collar with a channel for concentrically circumscribing the catheter.
Claim 21
Dependent Claim
20 words
The assembly of claim 15 wherein said retaining means is a radially extending support arm with a longitudinal circular channel.
