Abstract
Devices for controlling the flow of fluid through plastic tubes, such as tubes which are part of a disposable blood donation tubing set are disclosed. The device has a clamp adapted for attachment with one or more other clamps to allow for easy flow control through two or more tubing segments.
Claims24
A flow control device comprising:
- a first clamp comprising a body having a first end and a second end, said ends adapted for locking engagement with each other, a pair of apertures in said body for receiving a flexible tube, and at least one tubing contacting member for compressing said flexible tube;
- and
- a second clamp, in association with said first clamp, said second clamp comprising a body having a first end and a second end, said ends adapted for locking engagement with each other, a pair of apertures in said body for receiving a flexible tube, at least one tubing contacting member for compressing said flexible tube, and a releasing member for releasing said first clamp from a compressed position,
- wherein said first and second clamps are relatively positioned to allow said releasing member to contact said first clamp.
1 more element
A flow control device comprising:
- a body having a first end and second end, said ends adapted for locking engagement with each other;
- at least two apertures in said body for receiving a flexible tube therethrough;
- at least one tubing contacting member for compressing said flexible tube,
- a connector for mating with a receiving member of an adjacent flow control device;
- and
- a receiving member for mating with a connector of an adjacent flow control device.
3 more elements
A flow control device comprising:
- a body having a first end and a second end wherein said first end comprises a notch and said second end comprises a lip adapted for engagement with said notch, wherein at least a portion of said body including said second end is offset from the remainder of said body, said second end portion further comprising an extension laterally spaced from and axially extending beyond the portion of said lip adapted for engagement with said notch.
A flow control device comprising:
- (a) a first clamp comprising:
- a body having a first end and a second end, wherein said body comprises a notch and slot in proximity to but spaced from said first end and said second end comprises a lip adapted for engagement with said notch, at least two apertures in said body for receiving a flexible tube, and at least one tubing contacting member for compressing a flexible tube;
- and
- (b) a second clamp, adjacent to and in association with said first clamp, said second clamp comprising:
- a body having a first end and a second end, wherein said first end comprises a notch and said second end comprises a lip adapted for engagement with said notch, said lip further comprising an extension adapted for locking engagement with said slot of said first clamp, at least two apertures for receiving a flexible tube, at least one tubing contacting member for compressing a flexible tube;
- and
- wherein said extension is adapted for contact with said first end of said first clamp to release said first clamp lip from said first clamp notch.
4 more elements
A flow control device comprising:
- a first clamp comprising a body having a first end and a second end, said ends adapted for locking engagement with each other, a pair of apertures in said body for receiving a flexible tube, and at least one tubing contacting member for compressing said flexible tube;
- a second clamp, in association with said first clamp, said second clamp comprising a body having a first end and a second end, said ends adapted for locking engagement with each other, a pair of apertures in said body for receiving a flexible tube, at least one tubing contacting member for compressing said flexible tube;
- wherein said first and second clamps are relatively positioned such that engaging said first and second ends of one of said first and second clamps causes disengaging of said first and second ends of said other of said first and second clamps.
A flow control system comprising:
- a first clamp comprising a body having a first end and a second end, said ends adapted for locking engagement with each other, a pair of apertures in said body, a flexible tube defining a flow path and extending through said apertures, and at least one tubing contacting member for compressing said flexible tube to close said flow path;
- a second clamp, in association with said first clamp, said second clamp comprising a body having a first end and a second end, said ends adapted for locking engagement with each other, a pair of apertures in said body, a flexible tube defining a flow path and extending through said apertures of said second clamp, at least one tubing contacting member for compressing said flexible tube to close said flow path;
- wherein said first and second clamps are relatively positioned such that closing one flow path of said first and second clamps causes opening of said other flow path of said first and second clamps.
