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 fluid infusion device includes a housing having a reservoir chamber that receives a fluid reservoir. The fluid reservoir has a first end and a second end. The fluid infusion device includes a connector system having a first body section coupled to a second body section. The first body section defines a bore in communication with a chamber and a counterbore of the second body section to define a fluid flow path. The chamber of the second body section is in fluid communication with a vent subsystem defined through the second body section. The vent subsystem terminates in an outlet, and the vent subsystem is to direct gas in the fluid flow path through the second body section to the outlet. The fluid infusion device includes at least one ring disposed within the reservoir chamber that cooperates with the connector system to securely couple the connector system to the housing.

A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

A fluid delivery system is disclosed which comprises at least one supply station for supplying at least one fluid, a pressurizing unit for pressurizing said at least one fluid, an inlet fluid circuit in fluid communication with said at least one supply station and with a pump module of said pressurizing unit and an outlet fluid circuit in fluid communication with said pump module for discharging the fluid from the chamber. The chamber is provided with a piston reciprocating therein, thereby defining first and second variable-volume sub-chambers. The fluid delivery system further comprises a recirculation fluid circuit fluidically connecting said first and second variable-volume sub-chambers, and an actuator associated to said recirculation fluid circuit for managing the passage of said at least one fluid between said first and second variable-volume sub-chambers in both directions. A method of operating the fluid delivery system is also disclosed.

A system for controlled delivery of a medical fluid may include an elastomeric pump, a valve member fluidly coupled to the elastomeric pump at one side and a catheter at an opposite side for delivering the medical fluid to a patient, and tubing fluidly coupling the elastomeric pump and the valve member. The elastomeric pump may include an elastomeric membrane and a shell surrounding the elastomeric membrane. The pressure of the medical fluid may be greater than a pressure of the vein to keep the vein open. The valve member may be movable between an initial closed position, a fully open position where the medical fluid is delivered to the vein of the patient at a predetermined fluid flow rate, and at least one intermediate open flow position where the medical fluid is delivered to the vein of the patient at a flow rate below the predetermined fluid flow rate.

An implantable perfusion device (2) comprises a tubular transmission line (4) with an inlet end (6), an outlet end (8) and a flow restriction element (10) located therebetween, whereby an inlet section (12) of the transmission line is defined between the inlet end and the flow restriction element and whereby an outlet section (14) of the transmission line is defined between the flow restriction element and the outlet end. Moreover, the device comprises a perfusion chamber (16) containing a load of biologically active cells and is provided with a fluid entrance (18), a fluid exit (20) and a chamber volume (22) formed therebetween. The fluid entrance comprises at least one first microchannel platelet (24) and the fluid exit comprises at least one second microchannel platelet (26), each one of the microchannel platelets comprising at least one array of microchannels (28) defining a fluid passage between respective external and internal platelet faces, the microchannels having an opening of 0.2 to 10 μm. The fluid entrance (18) of the perfusion chamber is in fluid communication with the inlet section (12) of the transmission line; and the flow restriction element (10) is configured to establish a predetermined pressure excess in the inlet section (12) versus the outlet section (14).

A device for coupling to a fluid connector of an IV administration set to resist contamination of the fluid connector and IV administration set and permit priming of the IV administration set. The device including a cover body having a cavity for receiving the fluid connector, a priming passage for priming fluid from the IV administration set through the fluid connector, and a coupling tab extending from the cover body, the coupling tab permitting the cover body to be coupled to a length of an IV line or other portion of the IV administration set to resist contamination and permit priming of the IV administration set.

A drug delivery system includes a delivery container including a container body adapted to accommodate a drug therein, a supply line, a flow rate sensor, and a flow controller. The delivery container further includes an outlet port and is constructed from a resilient material. The container body is adapted to exert an urging force on the drug to expel the drug from the outlet port. The supply line is operably coupled to the outlet port to deliver the drug to a user.
