    Abstract: 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; a lever actuatable between a closed position and an open position; 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; and 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: A pump for pumping fluid, the pump comprising a tube platen; a plunger configured for actuation toward and away from the tube platen when the tube platen is disposed opposite to the plunger; a bias member configured to urge the plunger toward the tube platen; an inlet 5 valve upstream of the plunger configured for actuation between an occluding position and a non-occluding position; an outlet valve downstream of the plunger configured for actuation between an occluding position and a non-occluding position; an actuator mechanism configured to control the actuation of the plunger, the inlet valve and the outlet valve, wherein the actuator mechanism is configured to mechanically engage and disengage from 10 the plunger, wherein when the actuator mechanism is disengaged from the plunger, the actuator mechanism is configured to mechanically discharge the bias member such that the plunger is a sole force driving the plunger toward the tube platen, wherein the actuator mechanism is configured to engage the plunger to lift the plunger away from the tube platen to thereby mechanically charge the bias member; a pressure sensor disposed adjacent to at 15 least one of the inlet valve, the outlet valve, and the plunger; a position sensor configured to estimate a position of the plunger; and a processor coupled to the position sensor to receive the estimated position of the plunger therefrom. The processor is configured to detect an anomaly based in part on the estimated plunger position when: the inlet valve is in the occluding position, the outlet valve is in the occluding position, the actuator mechanism is 20 mechanically disengaged from the plunger thereby making the bias member the sole source of actuation force of the plunger toward the tube platen, and the bias member urges the plunger toward the tube platen. The processor is further coupled to the pressure sensor to receive a pressure signal from the pressure sensor, the processor is configured to, using the pressure signal, to determine a downstream occlusion exists if a subtraction of a filtered 25 value of a sequential series of sequential trough-to-trough pressure values of a plurality of cycles from a trough-to-trough value is greater than a predetermined threshold.

    Abstract: Se da a conocer una bomba para tratar un paciente que incluye un émbolo apretado por resorte apretado hacia el accionamiento contra un tubo; un árbol de leva configurado para accionar el émbolo basado en resorte; una palanca que puede accionarse entre una posición cerrada y una posición abierta; un árbol acoplado a la palanca, teniendo el árbol un eje central en el centro a lo largo de la longitud del árbol, el árbol acoplado a la palanca para rotar alrededor del eje central según el accionamiento de la palanca; y una leva de elevación acoplada de manera pivotante al árbol, en la que la leva de elevación pivota alrededor de un eje de leva de elevación, el eje de leva de elevación de la leva de elevación es paralelo al eje central del árbol, y la leva de elevación se engrana con el émbolo basado en resorte para elevar el émbolo apretado por resorte del árbol de leva a medida que el árbol rota según el accionamiento la palanca hasta la posición abierta.
