Abstract
Abstract Device for holding and positioning plastic tubing of an intravenous fluid administration set. Device comprises a generally flat, foldable, elongate structure having two outwardly extending arms connected via an intermediate flexible portion having on opposite sides thereof substantially parallel longitudinal recesses which, when the arms are folded against one another, form a longitudinal channel, generally circular in cross section and capable of holding plastic tubing via friction fit. In preferred embodiments, device includes means for irreversibly locking the arms together in a spring-like manner and a tamper prevention and indication means.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
103 words
A device for holding and positioning plastic tubing of an intravenous fluid administration set, the device comprising a generally flat, elongate and foldable polymer structure having two outwardly extending arms connected via an intermediate flexible portion adapted to serve as a hinge for the two arms, the flexible portion having on opposite sides thereof substantially parallel longitudinal recesses which, when the arms are folded against one another, form a longitudinal channel, generally circular in cross section and capable of holding plastic tubing via a relatively tight, but non-fluid-flow-reducing friction fit, the arms including means for irreversibly locking the arms in a closed position.
Claim 2
Independent Claim
103 words
A device for holding and positioning plastic tubing of an intravenous fluid administration set, the device comprising a generally flat, elongate and foldable polymer structure having two outwardly extending arms connected via an intermediate flexible portion adapted to serve as a hinge for the two arms, the flexible portion having on opposite sides thereof substantially parallel longitudinal recesses which, when the arms are folded against one another, form a longitudinal channel, generally circular in cross section and capable of holding plastic tubing via a relatively tight, but non-fluid-flow-reducing friction fit, the arms including means for irreversibly locking the arms in a closed position.
Claim 3
Dependent Claim
48 words
The device of claim 1 wherein at least one arm includes a projection adapted to be inserted into a slot in the opposite arm when the arms are folded together, the projection and opening in the opposite arm being located between the flexible portion and the locking means.
Claim 4
Dependent Claim
68 words
The device of claim 1 wherein at least one arm has a distal end and a proximal end adjacent the flexible portion, the thickness near the distal end being greater than the thickness at the proximal end, the thickness difference adapted to provide a compressed spring-like force between the arms and tending to push the arms apart when they are folded against each other in a locked position.
Claim 5
Dependent Claim
52 words
The device of claim 1 wherein at least one arm includes a scored portion of reduced thickness adapted to provide means for breaking that arm if an attempt is made to defeat the locking means by pulling the arms apart after they have been folded against one another in a locking relationship.
Claim 6
Independent Claim
150 words
A device for holding and positioning plastic tubing of an intravenous fluid administration set, the device comprising a generally flat, elongate and foldable structure having two outwardly extending arms connected via an intermediate flexible portion of reduced thickness, the flexible portion adapted to serve as a hinge for the two arms, the flexible portion having on adjacent sides thereof substantially parallel longitudinal recesses which, when the arms are folded against one another, form at least one longitudinal channel, generally circular in cross section and capable of holding plastic tubing in a relatively tight, but non-fluid-flow-reducing friction fit; the arms each including barb-like projections adapted to be irreversibly inserted into openings in the opposite arm when the arms are folded together; the arms comprising proximal ends connected to the flexible portion and outwardly extending distal ends, the thickness of the distal ends being greater than the thickness of the proximal ends.
Claim 7
Independent Claim
150 words
A device for holding and positioning plastic tubing of an intravenous fluid administration set, the device comprising a generally flat, elongate and foldable structure having two outwardly extending arms connected via an intermediate flexible portion of reduced thickness, the flexible portion adapted to serve as a hinge for the two arms, the flexible portion having on adjacent sides thereof substantially parallel longitudinal recesses which, when the arms are folded against one another, form at least one longitudinal channel, generally circular in cross section and capable of holding plastic tubing in a relatively tight, but non-fluid-flow-reducing friction fit; the arms each including barb-like projections adapted to be irreversibly inserted into openings in the opposite arm when the arms are folded together; the arms comprising proximal ends connected to the flexible portion and outwardly extending distal ends, the thickness of the distal ends being greater than the thickness of the proximal ends.
