First claim

What is claimed is:

1. A tube clamp for bioprocessing, comprising:
a first clamp member having a first end joined to a second end by a crescent shaped body comprising:
an interior having a groove extending along the crescent shaped body and including a lower surface joined to a sidewall and a top surface joined to the sidewall by a tapered surface, wherein the tapered surface is angled at forty-five degrees relative to the lower surface and the top surface;
an exterior surrounding the interior, the exterior including an exterior surface joined to an exterior sidewall by an exterior taper, the exterior taper is angled at forty-five degrees relative to the exterior surface and the exterior sidewall and the exterior sidewall is joined to the top surface;
a closure region joined to the first end; and
an attachment region joined to the second end; and

a second clamp member having a first end joined to a second end by a crescent shaped body comprising:
an interior including a groove extending along the crescent shaped body and including a lower surface joined to a sidewall and a top surface joined to the sidewall by a tapered surface, wherein the tapered surface is angled at forty-five degrees relative to the lower surface and the top surface;
an exterior surrounding the interior, the exterior including an exterior surface joined to an exterior sidewall by an exterior taper, the exterior taper is angled at forty-five degrees relative to the exterior surface and the exterior sidewall and the exterior sidewall is joined to the top surface;
a closure region joined to the first end; and
an attachment region joined to the second end.

2. The tube clamp for bioprocessing of claim 1 , wherein the closure region of the first clamp member includes two equally spaced apart prongs and each prong has a first end and a second end,
wherein the first ends are joined to the crescent shaped body and the second ends extend outwardly to create an opening,
wherein each prong includes a plurality of protrusions projecting off of an engagement surface.

3. The tube clamp for bioprocessing of claim 2 , wherein the closure region of the second clamp member includes two equally spaced apart prongs and each prong has a first end and a second end,
wherein the first ends are joined to the crescent shaped body and the second ends extend outwardly to create an opening and a cross member joins the second ends to enclose the opening,
wherein the first and second clamp members move relative to one another to form an open configuration and a closed configuration and in the closed configuration the engagement surface of the first clamp member comes into physical contact with an engagement surface of the second clamp member.

4. The tube clamp for bioprocessing of claim 3 , further comprising:
a screw having a first end and a second end, wherein the first end includes threads and at least one flat surface and the second end includes a head having a taper;
wherein the opening of the second clamp member includes a wide region that tapers to a narrow region and the narrow region includes at least one flat surface;
wherein the first end of the screw projects through the narrow region, the two flat surfaces are in physical contact to restrict horizontal movement and the taper of the head extends through the wide region and abuts the narrow region and cross member to restrict lateral movement of the screw.

5. The tube clamp for bioprocessing of claim 4 , further comprising a screw receiver having a first end and a second end, including:
a barrel surrounding an interior disposed on the second end of the screw receiver, wherein an opening on the second end accepts the screw and a set of complimentary grooves within the interior engages the threads of the screw to secure the first and second clamp members into the closed configuration; and
a handle disposed on the first end of the screw receiver and joined to the barrel.

6. The tube clamp for bioprocessing of claim 5 , wherein the handle further includes an uneven surface for gripping and the uneven surface includes a plurality of elongated channels.

7. The tube clamp for bioprocessing of claim 5 , wherein a disk having a plurality of openings extends laterally away from the barrel.

8. The tube clamp for bioprocessing of claim 7 , further comprising a securing member in physical contact with at least one of the plurality of openings on the disk and the cross member of the second clamp member.

9. The tube clamp for bioprocessing of claim 8 , wherein the securing member is a cable tie positioned to maintain the first and second clamp members in a closed position by drawing the at least one of the plurality of openings toward the cross member.

10. The tube clamp for bioprocessing of claim 5 , wherein the opening on the first clamp member includes a wide region and a narrow region that are joined by a shelf and a diameter of the barrel fits into the wide region and abuts the shelf in the closed configuration.

11. The tube clamp for bioprocessing of claim 1 , wherein the attachment region of the first clamp member includes a base surrounding an opening and the attachment region of the second clamp member includes a base having a projection extending therefrom, wherein the projection extends into the opening to allow the first and second clamp members move from an open configuration to a closed configuration.

12. The tube clamp for bioprocessing of claim 1 , further comprising:
wherein the closure region on the first clamp member includes a projection having a concave surface and the closure region on the second clamp member includes a projection and a bar cavity;
a first latch member including a body having a first end and a second end, the first latch member including a bar joined to the second end to engage the bar cavity, a convex surface joined to the first end to engage the concave surface, a projection opening to accept the projection on the first clamp member, and two projections extending outwardly from the body;
a second latch member including a body having a first end and a second end, the second latch member including two hooks surrounding two openings for engaging the protrusions on the first latch member, wherein actuating the first end of the second latch member causes the hooks to rotate about the protrusions.

13. The tube clamp for bioprocessing of claim 1 ,
wherein the closure region of the first clamp member includes an abutment joined to a hook by a surface and a barb extends from the hook toward the abutment, and
wherein the closure region of the second clamp member includes an abutting surface and a barb receiver that is joined to a hook protrusion,
wherein the abutment presses against the abutting surface, the hook engages the hook protrusion, and the barb receiver interlocks with the barb to maintain the closed configuration.

14. The tube clamp for bioprocessing of claim 13 , wherein the attachment region of the first clamp member includes an abutting surface and a barb receiver that is joined to a hook protrusion, and
wherein the attachment region of the second clamp member includes an abutment joined to a hook by a surface and a barb extends from the hook toward the abutment,
wherein the abutment presses against the abutting surface, the hook engages the hook protrusion, and the barb receiver interlocks with the barb to maintain the closed configuration.

15. A tube clamp for bioprocessing, comprising:
a first clamp member, comprising:
a first end joined to a second end by a crescent shaped body; and
a closure region joined to the first end;

a second clamp memb
