Abstract
Pinch clamps are provided which generate positive displacement while also preventing rebound. To prevent rebound while providing positive displacement, the upper and lower clamping surfaces may be configured to form a pinch profile along which the tubing is compressed with the pinch point being formed at the distal end of the pinch profile. To further prevent rebound, the lower arm of the pinch clamp can include blocking ribs that interface with the upper clamping surface to prevent distal travelling of the pinch point even if the upper arm is forced into an over-engaged position.
Claims4
A pinch clamp to clamp a medical tubing, comprising:
- a lower arm comprising a lower clamping surface, wherein the lower clamping surface comprises an upwardly protruding proximal portion and an upwardly protruding distal portion, wherein the upwardly protruding proximal portion protrudes upwardly further than the inwardly protruding distal portion;
- an upper arm comprising an upper clamping surface, wherein the upper clamping surface comprises a downwardly protruding proximal portion, a downwardly protruding distal portion, and a recessed portion between the downwardly protruding proximal portion and the downwardly protruding distal portion, wherein the upwardly protruding proximal portion is configured to insert into the recessed portion when the pinch clamp is in an engaged position, wherein the upwardly protruding distal portion is configured to be aligned with the downwardly protruding distal portion when the pinch clamp is in the engaged position;
- and
- a hinge disposed between the lower arm and the upper arm.
