摘要： A fluid delivery monitoring and control apparatus for use in a medication infusion system is designed for use with a disposable fluid pathway that incorporates a sterile cassette (12) containing pumping elements (28, 30, 32) and sensor interfaces. The apparatus comprises a multi-segment drive mechanism (14), controller (18) and monitoring system. Fluid pumping is accomplished by controlling DC motors (36) in the drive mechanism, each of which is coupled to two valves (28,32) and a reciprocating piston (30) for an individual pumping channel in the cassette. The motor is geared down to provide an approximate maximum speed and torque. A cam (38) sequentially actuates an inlet valve (28), piston (30), and an outlet valve (32) in the cassette. A range of fluid delivery rates is achieved by periodically sending pulses to the motor. The output flow rate of the pump is maintained by the digital feedback controller which uses a closed-loop feedback controller (60) to provide accurate regulation. At regular time intervals, the controller computes the motor voltage pulse width based upon feedback information from an encoder (46).

摘要： A system for detecting an occlusion in a fluid line in the downstream or patient side of a disposable cassette containing a fluid pump. The cassette includes a pressure diaphragm (170) and is for installation onto and use with a main pump unit including a pressure transducer (660) for monitoring fluid pressure downstream of the pump. An analog pressure signal is produced by a piezoresistive device (716) and this is converted to a digital signal by a quantizer (758) Control circuitry provides an alarm in the event of a patient-side occlusion using the pressure signal and a predicted pressure rate change signal. The occlusion detection system works when the system is configured as any of a number of different device types, including both a flow controller emulation and several different infusion pump configurations.

摘要： A mechanical drive system for use in driving a disposable cassette containing a reciprocating fluid pump and active valves from a main pump unit. The system uses a single power module cam (580) to drive both the reciprocating pump and the valves to eliminate the possibility of a timing error between the operation of the reciprocating pump and the valves. The power module cam (580) has a cam groove (590) which drives a pump actuator (540) and a bottom can surface (592) which drives two valve actuators (620).
