A volumetric fluid dispensing device can include a fluid reservoir having at least one flexible wall and a dispensing reservoir oriented above the fluid reservoir. The dispensing reservoir can have an overflow return fluidly connected to the fluid reservoir such that the dispensing reservoir holds a measured volume of fluid. A reservoir conduit can be fluidly connected to the fluid reservoir and the dispensing reservoir to allow excess fluid to return from the overflow to the fluid reservoir. A dispensing conduit can also be fluidly connected to the dispensing reservoir to allow fluid to exit the dispensing reservoir. A mechanical wall actuator can be operatively associated with the walls for controllably flexing at least a portion of the walls sufficient to force fluid from the fluid reservoir to the dispensing reservoir via the reservoir conduit.

Volumetric is fluid dispensing devices, systems, and methods

The present invention is directed to an integrated cartridge assembly for delivery of the biocompatible fluids to a subject, in which the device comprises an integrated cartridge including a fluid reservoir for housing the biocompatible fluid, a dispenser permanently and fluidically connected to the fluid reservoir, and configured for dispensing the biocompatible fluid to a manifold which is fluidically and removably connectable to the cartridge.

Replaceable supplies for IV fluid delivery systems

Bioactive agents are dosed by a jet dispenser using inkjet technology, such as that used in printing devices. A controller may control delivery of one or more drugs, timing of drug administration, or change drug regimens in response to a changing medical condition of a patient or information received from other nodes in a healthcare system. In a healthcare system, smart devices coupled to healthcare nodes can be in communication with the controller for controlling the administration of bioactive compositions from the jet dispenser.

System and methods for administering bioactive compositions

Methods of creating an internal channel of a fluid-ejection device are provided. One method includes encapsulating a channel core in an element of the fluid-ejection device that corresponds to the internal channel and dissolving at least a portion of the channel core.

Methods for creating channels

Bioactive agents are dosed by a jet dispenser using inkjet technology, such as that used in printing devices. The jet dispenser dispenses precise amounts of bioactive agent into a fluid manifold, in which the bioactive agent can be mixed with an infusion liquid for infusing into a patient. A controller may control delivery of one or more drugs, timing of drug administration, or change drug regimens in response to a changing medical condition of a patient. A drop detector can be used to detect various characteristics of the droplets of the bioactive agent dispensed by the jet dispenser and provide a feedback signal to the controller to determine whether a detected characteristic satisfies a predetermined condition. Methods for administering bioactive agents using a jet dispenser also are disclosed.

Apparatus and methods for administering bioactive compositions

A fluid-ejection assembly that includes a substantially-rigid substrate and an ejection head configured to be positioned in a fixed relationship relative to the substantially-rigid substrate. The ejection head is configured to eject a fluid based on an ejection signal received via a conductive pattern defined on the substrate.
