Abstract: Peristaltic pumps help infuse a patient with a fluid and typically have the benefit of isolating the medical fluid being infused into a patient in while maintaining sterility. A pump for treating a patient is disclosed that includes a spring- biased plunger biased toward actuation against a tube, a cam shaft configured to actuate the spring-based plunger, lever actuatable between a closed position and an open position. The pump also comprises a shaft coupled to the lever, the shaft having a central axis centrally along the length of the shaft, the shaft coupled to the lever to rotate around the central axis in accordance with actuation of the lever. The pump also comprises a lift cam pivotally coupled to the shaft, wherein the lift cam pivots around a lift cam axis, the lift cam axis of the lift cam is parallel to the central axis of the shaft, and the lift cam engages with the spring-based plunger to lift the spring-biased plunger off of the cam shaft as the shaft rotates in accordance with actuating the lever to the open position.

Abstract: Disclosed is a clamp apparatus which comprises a body with a pair of handles operatively coupled to the body; a pair of movable grippers, each coupled to a handle; and a first gear set operatively coupled to the first handle and a second gear set operatively coupled to the second handle, wherein the first gear set operatively engages the second gear set; and at least one bias member operatively engaged with the first handle and the second handle, wherein the at least one bias member is configured to urge the first and second movable grippers toward a clamped position. The clamp apparatus of the invention may provide for improved clamping and error reduction, particularly in the context of securing medical devices.

Abstract: Disclosed herein is a syringe pump, wherein the syringe pump comprises a half nut assembly that engages a motor driven lead screw, where a barrel cam with a projection engages a slot in the half nut cam follower surface so as to make the half nut engage or disengage with the lead screw. Also disclosed are related methods using the syringe pump, such as a method for removing effects of slack in a syringe pump having a syringe loaded on the syringe pump.

Abstract: A method for removing the effects of slack in a syringe pump having a syringe loaded on the syringe pump, the syringe having a barrel and a plunger disposed within the barrel, the method comprising receiving a target flow rate of the syringe loaded on the syringe pump, determining a therapy actuation speed corresponding to the target flow rate, actuating the plunger of the syringe out of the barrel at a first predetermined speed until a force sensor coupled to the plunger measures a force that is less than a first predetermined force threshold, actuating the plunger of the syringe into the barrel at a second predetermined speed greater than the therapy actuation speed until the force sensor coupled to the plunger measures a force that exceeds a second predetermined threshold, and actuating the plunger of the syringe into the barrel at the therapy actuation speed.

Abstract: A method for discharging fluid from a syringe and for mitigating occlusion conditions includes actuating the plunger of a syringe into a barrel. The method monitors fluid pressure within the barrel of the syringe and determines that an occlusion exists when the fluid pressure exceeds a predetermined threshold. The method actuates the plunger out of the barrel by a predetermined amount in response to the detected occlusion and actuates the plunger of the syringe into the barrel until a measured fluid pressure within the barrel of the syringe exceeds another predetermined threshold.
