An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

The present invention concerns a device for injecting a liquid product contained in a bag, the device comprising a housing consisting of two half-shells articulated about an axis of rotation in order to allow the relative movement of the half-shells relative to each other between: —an open position in order to put the bag in place and—a closed position for injecting the liquid product contained in the bag, remarkable in that: —one of the half-shells comprises a deformable bladder—called the “active bladder”—having a volume that varies under the action of a hydraulic ram supplying said bladder with hydraulic fluid, and—the other of the half-shells comprises a deformable damping cushion having a constant volume—called the “passive cushion”.

The problem of infusing air into IV tubing and into a patient from a IV fluid bag inside a pressure infusion cuff is solved by collar embodiments that inhibit the air from being forced into the IV tubing. A collar can include one or more curved arms that create a channel in which that part of the fluid bag is protected against being squeezed by a pressure infusion cuff. A collar allows the fluid bag to be squeezed by the pressure infusion cuff until such time that the fluid level is sufficiently reduced that the collar can inhibit further pressure on the fluid bag by the pressure infusion cuff. Also disclosed is a fluid bag and a pressure infusion cuff that are modified to have a collar incorporated therewith.

Chemical engines and processes for their use and construction are described. The chemical engines can provide powerful and compact devices, especially autoinjectors for the rapid, powered injection of viscous medicines. Novel formulations and designs of chemical engines and delivery technologies employing the chemical engines are described.

A pressurizable fluid supply apparatus may include a bag to hold a fluid. The bag may include a fluid outflow interface and a bladder positioned adjacent to the bag. The bladder may include a plurality of chambers positioned vertically in series. Adjacent chambers may be separated by dividers. The dividers may be configured to allow fluid flow between adjacent chambers under specified conditions. The bladder may further include a pressure inlet positioned at a top of the bladder.

An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion.

The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

In one aspect the present disclosure refers to a measuring arrangement for measuring of a volume change of a liquid medium located inside a liquid reservoir, the measuring arrangement comprising: a gas tight enclosure having an interior volume containing a gas reservoir and containing the liquid reservoir, wherein the liquid reservoir is filled with a liquid medium, a gas inlet in flow connection with the gas reservoir and extending through a boundary of the gas tight enclosure to an exterior of the gas tight enclosure, an outlet connectable with the liquid reservoir and extending through the boundary of the gas tight enclosure, wherein the gas reservoir and the liquid reservoir are hermetically separated by an impenetrable separation wall, and a flow meter arranged in or across the gas inlet to measure an ingress of a gaseous medium through the inlet in response to a withdrawal of the liquid medium from the liquid reservoir through the outlet.

Provided is a system for dispensing fluid. The system includes a housing defining a chamber; an inflatable bag disposed in the chamber and adapted to contain a fluid, the bag being in fluid communication with a flow path for flow of the fluid out of the bag; and a pressure source for inflating the bag to force the fluid from the bag to the flow path at a controlled rate. The bag inflates against an inner surface of the housing such that, prior to the bag being fully inflated, the fluid contained in the bag is forced from the bag at the controlled rate.

A device for injecting contrast agent includes a supply line with a pressure regulator and leading to a soft injection bag in fluid communication with the supply line and with a catheter. The device also includes a pair of clamping plates acting on the injection bag and arranged on opposite sides of the injection bag. The clamping plates can be moves away from and close to each other. The device also includes a pair of inflatable compression bags. The compression bags are inflated with compressed air and act on corresponding clamping to plates to force the clamping plates to move close to each other and thus compress the injection bag. According to a method of the invention, the injection bag is filled from the source through the pressure regulator and a constant volume load container, and a contrast agent is supplied from the injection bag by gradually compressing the injection bag.

A transport device configured to transport an IV product or medication from one location to another in automated fashion. The transport device may comprise a chassis with one or more ports for IV products. A drive mechanism is configured to move the transport device, and instructions for execution can be provided by a controller. Information may be provided to the controller about an IV product, such as its intended destination or use. The controller may also exchange information with a delivery location or device, such as an infusion pump, to verify that the IV product is delivered to the proper destination. The transport device may include a delivery mechanism for off-loading an IV product. The transport device may deliver IV products of various configurations, including configurations in which the product comprises a flexible bag and a container housing for supporting and protecting the fluid bag.
