Abstract:
1. A system for delivering a fluid at a desired flow rate 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 associated with the delivery channel for operatively delivering the fluid to the delivery point at an adjustable output rate; a flow sensor located along the delivery channel for sensing a flow of the fluid in the delivery channel, the flow sensor comprising a positive displacement flow sensor, the flow sensor comprising: a controller for controlling the pump; an optical reader associated with the flow sensor for generating a flow rate signal; and a wireless communication channel between the reader and the controller, the reader configured for providing the flow rate signal indicative of the flow rate via the wireless communication channel to the controller and the controller configured for receiving the flow rate signal via the wireless communication channel and causing adjustments to the adjustable output rate of the pump in response thereto.
