Abstract

A clamp for selectively compressing a portion of tubing, such as an extension leg of a PICC or other catheter, is disclosed. The clamp is able to be opened or closed with a thumb and finger of a single hand of a user and is slidably attached to the tubing so as to enable its placement as desired along the tube. In one embodiment, the tubing clamp comprises a body including first and second body portions hingedly connected to one another in a clamshell configuration, a latch for releasably latching the first and second body portions together, and at least two tube compression members. The tube compression members cooperate to compress and occlude a portion of tubing passing through the tubing clamp when the first and second body portions are latched to one another.

First claim

What is claimed is:

1. A tubing clamp, comprising:
a body including first and second body portions hingedly connected to one another in a clamshell configuration;
a latch for releasably latching the first and second body portions together in a closed position, wherein the latch includes a male latch portion and a female latch portion, wherein the male latch portion is included on the first body portion, the first body portion further including a compliant segment that enables a portion of the first body portion on which the male latch portion is disposed to compliantly deform;
at least two tube compression members that cooperate to compress and occlude a portion of tubing passing through the tubing clamp when the first and second body portions are in the closed position; and
at least two tube retention members designed to receive the portion of the tubing so as to secure the tubing clamp to the tubing, the at least two tube retention members each comprising a closed loop structure, a first of the at least two tube retention members positioned on the first body portion and a second of the at least two tube retention members positioned on the second body portion, the first and second tube retention members moving in opposite directions around a hinged connection when the first and second body portions move between an open position and the closed position.

2. The tubing clamp as defined in claim 1 , wherein the first body portion includes a first tube compression members disposed proximate the first tube retention member.

3. The tubing clamp as defined in claim 1 , wherein the at least two tube compression members comprises a first tube compression member and a second tube compression member, each of the first and second tube compression members including a flat surface for engaging a portion of the tubing, the flat surfaces facing one another when the tubing clamp is latched.

4. The tubing clamp as defined in claim 1 , wherein the at least two tube compression members comprises a first tube compression member and a second tube compression member, the first and second tube compression members including correspondingly shaped surfaces for engaging a portion of the tubing when the tubing clamp is latched.

5. The tubing clamp as defined in claim 4 , wherein the first tube compression member includes a convexly shaped surface and wherein the second tube compression member includes a concavely shaped surface.

6. The tubing clamp as defined in claim 1 , wherein the first and second body portions are integrally formed with one another.

7. The tubing clamp as defined in claim 6 , wherein a living hinge hingedly connects the first and second body portions.

8. The tubing clamp as defined in claim 1 , wherein the compliant segment includes a region of reduced cross-sectional area with respect to adjacent portions of the first body portion.

9. The tubing clamp as defined in claim 1 , wherein the first body portion includes a lip disposed proximate to the male latch portion, wherein a user presses proximate the lip during unlatching of the tubing clamp to cause the lip to assist in separating the first body portion from the second body portion.

10. The tubing clamp as defined in claim 9 , wherein the first body portion further includes gripping portions disposed proximate to the lip.

11. The tubing clamp as defined in claim 1 , wherein a hinge hingedly connects the first and second body portions, the hinge including a hook portion and a rod portion respectively disposed on the first and second body portions.

12. The tubing clamp as defined in claim 1 , wherein a hinge hingedly connects the first and second body portions, the hinge including a plurality of knuckles and a pin passing through the knuckles.

13. The tubing clamp as defined in claim 1 , wherein the first body portion includes a first of the at least two tube compression members disposed proximate the first tube retention member, wherein the at least two tube retention members each include the closed loop structure designed to receive the portion of tubing passing through the closed loop structure of each of the two tube retention members.

14. A method of using a tubing clamp to selectively occlude a portion of tubing, the method comprising:
grasping a clamp body slidably attached to the portion of tubing, the clamp body including first and second body portions hingedly connected to one another via a hinge in a clamshell-like configuration, a latch for releasably latching the first and second body portions together in a closed position, wherein the latch includes a male latch portion and a female latch portion, wherein the male latch portion is included on the first body portion, the first body portion further including a compliant segment that enables a portion of the first body portion on which the male latch portion is disposed to compliantly deform, at least two tube compression members, and at least two retention members, the at least two retention members encircling the portion of tubing and maintaining the portion of tubing in a substantially parallel orientation to an axis of the hinge; and
selectively latching the first and second body portions together via the latch, wherein the at least two tube compression members of the tubing clamp compress and occlude the portion of tubing when the first and second body portions are in the closed position.

15. The method of using the tubing clamp as defined in claim 14 , further comprising selectively unlatching the first and second body portions via the latch, wherein the at least two tube compression members no longer compress and occlude the portion of tubing.

16. The method of using the tubing clamp as defined in claim 15 , wherein the selective latching and unlatching of the first and second body portions is performed manually by a thumb and finger of a single hand of a user.

17. A tubing clamp, comprising:
a body including first and second body portions hingedly connected to one another in a clamshell-like configuration, the first and second body portions each having a convex shape and together providing a continuous outer surface over a perimeter thereof in a closed position, the first body portion including a compliant segment;
a latch for releasably latching the first and second body portions together in the closed position, the latch including a male latch portion disposed on the compliant segment of the first body portion and a female latch member on the second body portion;
first and second tube compression members respectively included on the first and second body portions that cooperate to compress a portion of compliant tubing passing through the tubing clamp when the first and second body portions are latched together so as to occlude the passage of fluids through the tubing;
at least two retention members encircling the portion of compliant tubing and maintaining the portion of compliant tubing in a substantially parallel orientation to an axis of a hinge.

18. The tubing clamp as defined in claim 17 , further comprising at least one tube retention member that enables the tubing clamp to slide along the portion of compliant tubing when the first and second body portions are unlatched.

19. The tubing clamp as defined in claim 18 , wherein the first and second body portions include a thermoplastic and are integrally connected via a living hinge, and wherein the first and second tube compression members each include a flat surface, the flat surfaces aligning when the first and second body portions are latched and cooperating to compress t
