Abstract

A flexible tube occluder has a body portion and a slider portion which act to occlude a tube to prevent unwanted flow of fluid to a patient. The body portion and slider portion are engaged such that slider portion can move relative to body portion. The body portion extends the full range of slider portion'"'"'s motion and thus the occluder allows for stable occluding and open positions. The slider portion has a slot of varying size which is used to occlude the tube by pressing the tube within the surface of the slot and to allow free flow of fluid through the tube.

Claims

1. A device for occluding tubing, comprising:

a first member having a body portion defining a periphery and having at least one guide portion, said first member also defining a hole for receiving the tubing to be occluded, wherein said periphery surrounds without intersecting said tubing; and

a second member slidably secured to the first member and being retained by said at least one guide portion, said second member slidable between an occluding position and a non-occluding position such that the second member cooperates with the first member to alternately occlude and non-occlude the tubing corresponse to the movement of the second member, wherein the second member in both the occluding position and the non-occluding position is retained within an area defined by the periphery of the first member body portion, thereby protecting the second member from unintended actuation.

2. The device of claim 1, wherein the second member defines an elongated slot having a tapered opening with wider and narrower ends for receiving a tube to be occluded therethrough, wherein said wider end is aligned with said first member hole in the non-occluding position and said narrower end is aligned with said first member hole in the occluding position.

3. The device of claim 1, wherein:

said first member body portion comprises a body member having two opposed ends and two opposed sides; and

said at least one guide portion comprises a rail member extending downward from each said side of the body member and surrounding a part of the second member, thereby slidably retaining said second member.

4. The device of claim 3, wherein said first body portion includes at least one stop member positioned to prevent movement of the second member beyond the periphery of the first member.

5. The device of claim 1, wherein said first member body portion includes surface defining a plane in which said hole and said periphery lie, and wherein said second member includes an actuating member extending away from said plane.

6. The device of claim 5, wherein said actuating member extends substantially perpendicularly to the plane.

7. A device for selectively preventing fluid flow through a flexible tube having an outer diameter, comprising:

a first member having first and second end and defining a first member periphery and a first opening lying within said periphery for receiving the tube therein; and

a second member defining a second opening for receiving the tube therein, said second member being movable relative to the first member thereby defining a range of motion, wherein said second member is contained within said first member periphery over said range of motion of the second member and the second member is movable relative to the tube such that said movement causes the second member to alternate between an open position wherein fluid can flow through the tube and an occluding position wherein the tube is occluded by the second member,

wherein the first member further comprises at least one guide wherein the second member is movable along said at least one guide over the range of motion and said at least one guide secures the second member to the first member for sliding movement there between.

8. A device for selectively preventing fluid flow through a flexible tube having an outer diameter, comprising:

a first member having first and second end and defining a first member periphery and a first opening lying within said periphery for receiving the tube therein; and

a second member defining a second opening for receiving the tube therein, said second member being movable relative to the first member thereby defining a range of motion, wherein said second member is contained within said first member periphery over said range of motion of the second member and the second member is movable relative to the tube such that said movement causes the second member to alternate between an open position wherein fluid can flow through the tube and an occluding position wherein the tube is occluded by the second member,

wherein the first member comprises a first end portion made of a clear material and a second end portion made of an opaque material such that the second member is visible to an observer when in the first end portion.

9. A tube occluder, comprising:

a body member defining a body member periphery and including a fitment element lying within said body member periphery for securing a tube therein such that a periphery projection of said body member periphery onto a plane would surround a fitment projection of a portion of said fitment element which is connected to said body member onto said plane; and

a slider member having an opening for receiving the tube therethrough movable relative to the body member thereby defining a range of motion for the slider member, said slider member movement causes said slider member to cooperate with the body member to selectively occlude the tube; and

means for limiting the range of motion of said slider member such that a slider member projection of said slider member onto said plane is within said periphery projection.

10. The tube occluder of claim 9, wherein the fitment element comprises means for guiding the tube to the body member and the slider member.

11. The tube occluder of claim 10, wherein the means for guiding the tube comprises means for retaining the tube in the fitment element and the slider member opening.

12. The tube occluder of claim 9, wherein the slider member opening comprises a tapered slot.

13. The tube occluder of claim 12, wherein the slot comprises means for contacting and compressing the tube.

14. The tube occluder of claim 12, wherein the slot comprises means for allowing free flow through the tube.

15. The tube occluder of claim 9, wherein said slider member has a surface defining said opening, said tube occluder further comprising a grip extending away from said surface such that the slider member and the grip are retained within said body member periphery.

16. A device for occluding tubing, comprising:

a first member defining a hole for receiving tubing and having a first surface through which said hole extends and which has at least one edge which defines an enclosed perimeter;

a second member slidably connected to said first member and positioned within said perimeter of said first surface such that said first surface covers said second member, said second member defining a slot having a first end which slidably aligns with said hole and receives said tubing in a non-occluded form and a second end which is more narrow than said first end and which alternatively slidably aligns with said hole and occludes said tubing; and

means for restricting the travel of said second member to within said perimeter of said first surface.

17. The device of claim 16 wherein said first surface is planar.

18. The device of claim 16 wherein said means for restricting includes at least two edges of said first member.

19. The device of claim 16 further comprising at least one guide portion connected to said first member and slidably connected to said second member, and wherein said means for restricting includes at least two stops positioned at opposite ends of said at least one guide portion.
