First Claim
Patent Images
1. A peristaltic pump selectively movable between an open position and a closed position, comprising:
- a pump body; and
a support structure, wherein said pump body and said support structure are in a facing relationship with each other, at least one of said pump body and said support structure including locating features so that said support structure is at a fixed location with respect to said pump body when said pump is in the closed position and wherein as said support structure moves with respect to said pump body, said pump body moves between said open position and said closed position.

Abstract
A peristaltic pump for pumping fluids through a flexible tube has a pump body, a support structure, a tube retaining mechanism and a linkage mechanism. Locating features make sure that the support structure is at a fixed location with respect to the pump body when the pump is in the closed position. The support structure controls movement of the retaining mechanism. The linkage mechanism applies the necessary force to move the support structure so that the pump is moved from an open position to a closed position.

24. A peristaltic pump comprising:
-
a pump body; and
a support structure, wherein said support structure includes a front face, an arcuate working surface extending away from said front face;
a rear face, a bearing track extending away from said rear face, said bearing track including an arcuate surface, a centerpoint of both said arcuate working surface and said bearing track being coincident with one another; and
an opening, said opening including sloped lateral edges approaching an apex toward a bottom edge of said support structure. - View Dependent Claims (25, 26, 27, 28, 30, 31)

29. A peristaltic pump comprising:
-
a pump body;
a support structure; and
a tube retaining mechanism having a retainer carrier with a fixed retainer, said tube retaining mechanism further having a movable retainer;
selective movement of said movable retainer being determined by selective movement of said support structure.

32. A peristaltic pump comprising:
-
a pump body;
a support structure;
a linkage mechanism, which includes an actuating lever and a link arm, a pivot point permitting said actuating lever to pivot about said link arm;
wherein a first end of said linkage mechanism is selectively connected to said support structure and a second end of said linkage mechanism is selectively connected to said pump body, said pivot point disposed between said first end and said second end; and
wherein when said actuating lever is in a closed position, said linkage mechanism locks said support structure to said pump body to lock said pump. - View Dependent Claims (33, 34, 35, 36)

37. A peristaltic pump comprising:
-
a pump body; and
a support structure, wherein said support structure includes a front face, an arcuate working surface extending away from said front face;
a rear face, a bearing track extending away from said rear face, said bearing track including an arcuate surface, a centerpoint of both said arcuate working surface and said bearing track being coincident with one another; and
an opening, said opening including sloped lateral edges approaching an apex toward a bottom edge of said support structure;
a tube retaining mechanism, said tube retaining mechanism having a retainer carrier with a fixed retainer, said tube retaining mechanism further having a movable retainer;
selective movement of said movable retainer being determined by selective movement of said sloped lateral edges of said support structure; and
a linkage mechanism, said linkage mechanism including an actuating lever and a link arm, a pivot point permitting said actuating lever to pivot about said link arm;
wherein a first end of said linkage mechanism is selectively connected to said bearing track and a second end of said linkage mechanism is selectively connected to said pump body, said pivot point being disposed between said first end and said second end; and
wherein when said actuating lever is in a closed position, said linkage mechanism locks said support structure to said pump body to lock said pump. - View Dependent Claims (38, 39)
