Abstract:
1. A system for delivering a fluid at a desired pulsatile flow profile from a reservoir to a delivery point associated with a patient, the system comprising: a delivery channel between the reservoir and the delivery point through which the fluid is delivered to the patient; a pump including an actuator, the pump associated with the delivery channel for operatively delivering the fluid to the delivery point at an adjustable output rate; a flow sensor physically separate from the pump and located along the delivery channel upstream or downstream from the pump for sensing a flow of the fluid in the delivery channel and for generating a flow rate signal indicative of a rate of flow of the fluid in the delivery channel, the flow sensor comprising a positive displacement flow sensor including: a controller for controlling the pump, the controller causing adjustments to the output rate of the pump as a function of the flow rate signal such that the output flow rate has a generally pulsatile characteristic corresponding to the desired pulsatile flow profile.
