Abstract
Abstract A clamp for regulating the flow of parenteral solutions is disclosed which includes a clamp body having a channel for accommodating a length of administration set tubing so that a portion of the tubing is compressed to a closed position while at least one side of the tubing is left uncompressed to provide a passageway for the solution. A cam member or platen is moveably mounted on the clamp body for applying an adjustable compressive force against the uncompressed side of the tubing to vary the area of the passageway and the rate of flow of the solution.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
158 words
In a clamp for regulating the flow of fluid through a length of flexible tubing the combination which comprises: (a) a clamp body defining a surface for supporting the flexible tubing, opposing walls extending from the support surface for providing a passageway for the tubing, and a top surface extending above and overlying a portion of the support surface which extends between the walls for permanently compressing the portion of the tubing positioned between the top and support surfaces into a closed position while allowing the uncompressed portion of the tubing to form an open channel for the flow of fluid therethrough; and (b) platen means moveably mounted on the clamp body and arranged to exert an incremental compressive force on the portion of the tubing forming the open channel to thereby control the size of channel and regulate the flow of fluid therethrough, said permanently compressed tubing portion being independent of the movement of said platen means.
Claim 2
Dependent Claim
158 words
In a clamp for regulating the flow of fluid through a length of flexible tubing the combination which comprises: (a) a clamp body defining a surface for supporting the flexible tubing, opposing walls extending from the support surface for providing a passageway for the tubing, and a top surface extending above and overlying a portion of the support surface which extends between the walls for permanently compressing the portion of the tubing positioned between the top and support surfaces into a closed position while allowing the uncompressed portion of the tubing to form an open channel for the flow of fluid therethrough; and (b) platen means moveably mounted on the clamp body and arranged to exert an incremental compressive force on the portion of the tubing forming the open channel to thereby control the size of channel and regulate the flow of fluid therethrough, said permanently compressed tubing portion being independent of the movement of said platen means.
Claim 3
Dependent Claim
29 words
The tubing clamp of claim 1 wherein the top surface abuts one wall so that the side of the tubing remote from said one wall forms the open channel.
Claim 4
Dependent Claim
29 words
The tubing clamp of claim 1 wherein the top surface extends over the central portion of the tubing so that each side of the tubing forms an open channel.
Claim 5
Dependent Claim
68 words
The tubing clamp of claim 1, wherein the platen means comprises a cam member pivotably mounted on the clamp body, the cam member having a lever extending from the clamp body and a cam surface extending above the support surface for engaging the tubing, the distance between the cam surface and support surface and the size of the open channel being regulated by the position of the lever.
Claim 6
Dependent Claim
45 words
The tubing clamp of claim 4, wherein the top surface abuts one wall so that the side of the tubing remote from said one wall forms an open channel and wherein the cam surface engages the side of the tubing which forms the open channel.
Claim 7
Dependent Claim
41 words
The tubing clamp of claim 4, wherein the top surface extends over the central portion of the support surface so that each side of the tubing forms an open channel and wherein the cam surface engages each side of the tubing.
Claim 8
Dependent Claim
120 words
In a clamp for incrementally regulating the flow of fluid through a flexible tubing the combination which comprises: (a) a clamp body defining a channel for accomodating a length of the flexible tubing including means for permanently compressing to a substantially closed position a portion of the tubing while allowing at least one side of the tubing to provide a passageway for the flow of fluid therethrough; and (b) means moveably mounted on the clamp body for applying a regulated compressive force to said one side of the tubing to thereby control the area of the passageway and the rate of liquid flowing through the tubing, said permanently compressed tubing portion being independent of the movement of said movable means.
Claim 9
Dependent Claim
120 words
In a clamp for incrementally regulating the flow of fluid through a flexible tubing the combination which comprises: (a) a clamp body defining a channel for accomodating a length of the flexible tubing including means for permanently compressing to a substantially closed position a portion of the tubing while allowing at least one side of the tubing to provide a passageway for the flow of fluid therethrough; and (b) means moveably mounted on the clamp body for applying a regulated compressive force to said one side of the tubing to thereby control the area of the passageway and the rate of liquid flowing through the tubing, said permanently compressed tubing portion being independent of the movement of said movable means.
Claim 10
Dependent Claim
19 words
The clamp of claim 7 wherein the compressing means is arranged to compress the other side of the tubing.
Claim 11
Dependent Claim
36 words
The clamp of claim 7, wherein the compressing means is arranged to compress the center portion of the tubing while allowing both sides of the tubing to provide a passageway for the flow of fluid therethrough.
Claim 12
Dependent Claim
25 words
The clamp of claim 8, wherein the means moveably mounted on the clamp body is a platen which engages said one side of the tubing.
Claim 13
Dependent Claim
24 words
The clamp of claim 9, wherein the means moveably mounted on the clamp body is a platen which engages each side of the tubing.
Claim 14
Dependent Claim
72 words
The clamp of claim 7, wherein the clamp body defines an elongated channel having a bottom support surface a pair of opposing upstanding walls and a top surface extending over a portion of the bottom surface while allowing a portion of the tubing to extend between the top surface and at least wall, the compressing means comprising the top surface and the portion of the bottom surface extending below said top surface.
Claim 15
Dependent Claim
34 words
The clamp of claim 12, wherein the top surface extends from one wall to allow the side of the tubing remote from said one wall to provide a passageway for the flow of fluid.
Claim 16
Dependent Claim
35 words
The clamp of claim 12, wherein the top surface extends over the central portion of the bottom support surface to allow both sides of the tubing to provide a pasageway for the flow of fluid.
