Abstract
A rotary type of peristaltic pump having the rotor member mounted on one side thereof and including a swing arm rotatably mounted along the side of the peristaltic pump such that the swing arm is movable between a fluid delivery set loading open position and a pair of closed positions which automatically align and stretch a portion of the fluid delivery set around the rotor member to allow for the convenient loading of the fluid delivery set on the peristaltic pump and to ensure that the fluid delivery set is properly aligned about the rotor member of the peristaltic pump. A latch member on the swing arm provides a secondary position wherein the flow of fluid through the fluid delivery set is prevented.
Claims20
A fluid infusion device for delivering fluid to a patient comprising:
- a housing assembly;
- an infusion control means operatively associated with said housing assembly;
- and
- a swing arm including an actuatable latch means associated therewith, said swing arm bring operatively mounted on said housing assembly and adapted to be rotatable about said infusion control means between an open position wherein a fluid delivery set may be operatively inserted thereon and a plurality of closed positions wherein said latch means is generally adjacent said housing assembly, said latch means being operatively movable between a first position wherein said latch means engages said housing assembly to retain said swing arm in one of said closed positions and another position of said latch means wherein said swing arm is releasable from said one of said closed positions.
A fluid infusion device for delivering fluid to a patient comprising:
- a housing assembly;
- an infusion control means operatively associated with said housing assembly;
- and
- a swing arm including an actuatable latch means associated therewith, said swing arm being operatively mounted on said housing assembly and adapted to be rotatable about said infusion control means between an open position wherein a fluid delivery set may be operatively inserted thereon and a closed positions wherein said fluid delivery set is operatively positioned about said infusion control means, said latch means being operatively movable between a first positions wherein said latch means engages said housing assembly to retain said swing arm in said closed positions and another position wherein said swing arm is releasable from said closed position;
- and
- wherein said swing arm is movable between first and second closed positions and the flow of fluid through said fluid delivery set is prevented in said first closed position and operation of said infusion control means is enabled in said second closed position.
A fluid infusion device for delivering fluid to a patient, comprising:
- a housing assembly including an infusion control means operatively associated therewith;
- a fluid delivery set adapted to be operatively mounted adjacent said infusion control means;
- a swing arm including a latch means operatively associated with said swing arm wherein said swing arm is operatively mounted on said housing assembly and adapted to be rotatable about said infusion control means between an open position wherein said delivery set is adapted to be received on said swing arm and said housing assembly and a plurality of closed positions wherein said latch means is generally adjacent said housing assembly;
- and
- wherein said latch means is movable between a first positions wherein said swing arm is retained in one of said closed positions and a second position wherein said swing arm is releasable from said one of said closed positions.
A fluid device for delivering fluid to a patient, comprising:
- a housing assembly including an infusion control means operatively associated therewith;
- a fluid delivery set including first, second and third portions thereon and adapted to allow the controlled flow of fluid therethrough;
- a swing arm including a latch means operatively associated therewith wherein said swing arm is operatively mounted on said housing assembly and adapted to be rotatable about said infusion control means between an open position wherein said first and third portions of said delivery set are adapted to be operatively mounted on said swing arm and said housing assembly and a plurality of closed positions wherein said latch means is generally adjacent said housing assembly;
- and
- wherein said latch means is biased to remain in a first position wherein said swing arm is retained in said on of said closed positions and said latch means is movable to a second positions wherein said swing arm is releasable from sad one of said closed positions.
