Abstract

A clamp is provided. The clamp includes a flexible uniform body. The flexible uniform body includes an aperture configured to allow a tubing to pass through the flexible uniform body. The aperture is configured to allow unrestricted flow of a fluid within the tubing when the tubing is at a first position of the aperture and restrict the flow of the fluid within the tubing when the tubing is at a second position of the aperture. The flexible uniform body includes an engageable coupling mechanism disposed at a first portion of the flexible uniform body. The coupling mechanism is configured to, when engaged, cover at least a portion of a release point of the aperture such that the tubing is locked in place within a pinch point of the aperture.

Claims (30)

1 . A clamp, comprising:

a flexible body including:

an aperture configured to allow a tubing to pass through the flexible body, wherein:

a first end of the aperture comprises a release point configured to allow unrestricted flow of a fluid within the tubing when the tubing is positioned at the first end of the aperture, and

a second end of the aperture comprises a pinch point configured to restrict the flow of the fluid within the tubing when the tubing is positioned at the second end of the aperture; and

an engageable coupling mechanism disposed at a first portion of the flexible body, the coupling mechanism configured to, when engaged, cover at least a portion of the release point of the aperture such that the tubing is locked in place within the pinch point of the aperture.

2 . The clamp of claim 1 , wherein the coupling mechanism, when engaged, couples to a second portion of the flexible body opposite the first portion such that (i) the first portion of the flexible body is folded, at least in part, over the second portion of the flexible body and (ii) the first end of the aperture is covered.

3 . The clamp of claim 1 , wherein the coupling mechanism is a clasp configured to attach to a second portion of the flexible body.

4 . The clamp of claim 1 , wherein a second portion of the flexible body includes a mating hole and the coupling mechanism is configured to couple to the mating hole.

5 . The clamp of claim 1 , wherein the pinch point is configured to receive at least three different sized intravenous tubes.

6 . The clamp of claim 1 , wherein the pinch point is a flexible pinch point configured to receive at least six different sized intravenous tubes.

7 . The clamp of claim 1 , wherein the first portion of the flexible body includes a hinge such that when the engageable coupling mechanism is engaged a portion of the flexible body rotates about the hinge folding over the flexible body.

8 . The clamp of claim 7 , wherein the first portion of the flexible body and a second portion of the flexible body are individual components coupled together via the hinge.

9 . The clamp of claim 1 , wherein the flexible body includes an opening extending from an outer edge of the flexible body to the aperture, the opening configured to receive the tubing.

10 . The clamp of claim 1 , wherein the flexible body is molded.

11 . The clamp of claim 1 , wherein the flexible body is a flexible uniform body.

12 . The clamp of claim 1 , wherein the flexible body is formed on the tubing.

13 . A clamp, comprising:

a flexible body including:

a first area having a first width equal to at least a diameter of a tubing to allow unrestricted flow;

a second area having a second width substantially less than the diameter of the tubing to restrict the flow;

a transition area connecting the first area and the second area whereby a width of the transition area decreases from the first width to the second width; and

an engageable coupling mechanism disposed at a first portion of the flexible body, the coupling mechanism configured to, when engaged, cover at least a portion of the first area such that the tubing is locked in place within the first area or the second area.

14 . The clamp of claim 13 , wherein the coupling mechanism, when engaged, increases a rigidity of the flexible body such that the second width of the second area does not increase when the tubing is disposed in the second area.

15 . The clamp of claim 13 , further comprising an opening extending from an outer edge of the flexible body to the first area, the opening configured to receive the tubing.

16 . The clamp of claim 13 , wherein the coupling mechanism is a clasp configured to attach to a second portion of the flexible body.

17 . The clamp of claim 13 , wherein a second portion of the flexible body includes a mating hole and the coupling mechanism is configured to couple to the mating hole.

18 . The clamp of claim 13 , wherein the flexible body is molded.

19 . The clamp of claim 13 , wherein the flexible body is a flexible uniform body.

20 . The clamp of claim 13 , wherein the flexible body is formed on the tubing.
