Abstract: An infusion pump, suitable for medical applications, has a movable carriage (20) which is arranged gradually to depress the plunger (16) of a syringe (10). The carriage moves along a fixed rod (22) at a rate determined by the rotation of a lead-screw (28). Any excess pressure in the infusion line (11) produces a back-pressure on the plunger which causes an axial force to be exerted on the carriage and thus on the lead-screw. When this force exceeds a predetermined value, indicative of an occlusion of the infusion line, the lead-screw will move axially so compressing a spring (46) and causing a clutch (32) to become decoupled, causing infusion to cease and an alarm to sound.

Abstract: An improved medication infusion pump is provided of the type for receiving and supporting a medication-containing syringe, wherein the pump and syringe include matingly interfitted components to ensure use of the pump with a compatible and correctly installed syringe. The infusion pump comprises a pump housing defining a syringe compartment for receiving and supporting the syringe, in combination with a drive member for engaging and programmably displacing a syringe plunger to administer medication to a patient. In one preferred form, the drive member and plunger include a matingly interfitting tab and notch which are engaged when the syringe is fully and properly positioned within the syringe compartment. In another form, the tab and notch are formed on the syringe plunger and a portion of the pump housing.

Abstract: The present invention provides a syringe and a powered injector for use therewith in which the syringe is attachable to a powered drive member of an injector over a range of relative axial positions of the syringe plunger and the drive member. The syringe comprises a plunger, and a plunger extension connected thereto and extending rearward from the plunger, such that the syringe may be operated manually or by a powered injector. By providing a plurality of cooperating attachment members over a range of axial positions on at least one of the plunger extension or the powered drive member, operative attachment of the plunger and the drive member is made possible at multiple axial positions of the plunger (within the syringe) for each axial position of the drive member over at least a range of possible plunger axial positions. Attachment of the plunger to the drive member at various axial positions of the plunger thus becomes an easier task than previously possible with current powered injector systems.
