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: The invention provides a pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a door having a lever and an interlock, a pressure sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The bias member urges the plunger toward the tube platen. The inlet valve is upstream of the plunger and is configured for actuation between an occluding position and a non-occluding position. The outlet valve is downstream of the plunger and is configured for actuation between an occluding position and a non-occluding position. The actuator mechanism is configured to control the actuation of the plunger, the inlet valve and the outlet valve. The interlock is configured to mechanically engage the lever when the door is in an open position. The pressure sensor is disposed adjacent to at least one of the inlet valve, the outlet valve, and the plunger. The processor is coupled to the pressure sensor to receive a pressure signal from the pressure sensor. The inlet valve, the outlet valve, and the plunger are configured to pump fluid in a plurality of cycles, each cycle having a trough pressure level and a peak pressure level. By measuring variance in pressure levels, the pump is able to determine the presence of downstream occlusion which prevents or restricts pumping of the fluid.

Abstract: Provided is a pump for pumping fluid which includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a pressure sensor, and a processor. The processor is configured to determine a downstream occlusion exists dependent on one or more pressure signals received from the pressure sensor. The plunger is configured to engage and disengage from the actuator mechanism and the pressure sensor is configured to measure the peak pressure level after the plunger disengages from the actuator in each cycle. Such an arrangement permits a pump which provides efficient and accurate notice of downstream occlusion in order to promote patient safety.
