An infusion apparatus includes a housing and a chamber configured to be connected to the housing. The apparatus further includes a weight sensor coupled to a load connector connected to the housing and an optical sensor disposed in the housing. The weight sensor is configured to generate a first signal based on a measured weight of the fluid container attached to the housing in a weight-bearing configuration. The optical sensor is configured to generate a second signal based on detecting drops of the fluid traversing the chamber. The apparatus also includes a flow control mechanism to control a flow rate of the fluid into an outlet channel. The apparatus includes one or more processing devices configured to perform operations including transmitting a control signal to the flow control mechanism to adjust the flow rate.

An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.

A system for delivering a medicinal fluid to a patient includes a variable volume pressure delivery chamber, a variable volume medication chamber, an optional medication reservoir, a movable delivery element, a fixed reference volume chamber, a pressure source, and a control sub-system. The variable volume pressure delivery chamber is configured to store pressure controllably. The variable volume medication chamber is fluidically isolated from the pressure delivery chamber and is configured to store medicinal fluid. The movable delivery element is disposed between the medication chamber and the pressure delivery chamber. The pressure source is coupled to the pressure delivery chamber. The control system is configured to selectively cause the pressure source to deliver pressure to the pressure delivery chamber causing the movable delivery element to apply pressure to the medicinal fluid in the medication chamber thereby causing the medicinal fluid to exit the medication chamber at an outlet along the fluid communication path to the patient.

A fluid therapy method for an ADHF patient includes setting a urine output rate desired threshold, setting one or more desired negative net gain rates, and optionally setting a total fluid loss goal. The urine output of the patient is monitored and fluid is automatically administered to the patient at increasing rates to equal to or approximately match the patient's increasing urine output rates until the patient's urine output rate reaches the set urine output rate desired threshold. Thereafter, fluid is administered to the patient at rates to achieve the set desired negative net gain rate until the fluid loss goal is reached. Thereafter, until the end of therapy, fluid is administered to the patient at rates equal to or approximately equal to the monitored urine output rates.
