Abstract: A naso-gastric feeding tube (10) includes a hollow, flexible tube (12) having an open, proximal end (14) permanently secured to a hollow adapter (16), forming an integral unit. A stylet (56) is removably mounted within the stylet port (42) of the adaptor (16). A syringe (72) may be secured to the placement port (44) in order to conduct the placement confirmation test to assure proper insertion of the feeding tube within the patient, eliminating the need for removing and then reinserting the stylet to confirm proper insertion of the feeding tube (10). Additionally, the feeding tube (10) permits delivery of a second prescribed product without disconnecting the tube (10) from the source of the first prescribed product.

Abstract: A flexible collapsible container is filled with fluid by connecting a fluid conduit to a tubular port which communicates through one of the walls of the container to the container interior, and rupturing a sealing diaphragm that closes the bore of the tubular port. One then passes fluid through the conduit to fill the container. Thereafter, one seals either or both the tubular port and plastic wall which carries it to the other, opposed plastic wall of the container with seal line means to close off flow communication between the bore of the tubular port and a major portion of the container interior which contains the fluid. The effect of this is to block flow communication between the bore and the fluid so that the contents of the container remain sealed on disengagement of the fluid conduit from the tubular port.

Abstract: The present invention provides a sterile, unitized, economical device furnishing a fluid path between a plurality of solutions to be compounded and a receiving container. The device includes a plurality of fluid connectors and fluid lines sealingly connected to respective pump fittings which provide individual paths to a common junction block.The common junction block includes a portion for receiving fluid lines and preventing them from crimping thereby maintaining fluid flow. The block also includes an exit port for providing a sealingly sterile connection to the receiving container. Further, a closure is provided to protect the exit port from contamination when the port is not providing fluid communication to the receiving container.

Abstract: A device is described for accurately transferring multiple individual fluids from multiple source containers into a single receiving container. Fluid flows from the multiple source containers through individual fluid conduits to a chamber having a single fluid outlet conduit. The fluid outlet conduit is in fluid communication with a single receiving container. A pressure conduit is in communication with the chamber for alternately creating positive and negative pressures in the chamber to cause fluid to flow from the individual source containers into the chamber, and to cause fluid flow from the chamber into the receiving container in response to commands from a controller.

Abstract: A dispensing arrangement in a fluid line that isolates a region of fluid in the line from pressure effects in the line outside the region. A housing of measuring fluid surrounds the region so that changes in the measurement fluid pressure cause changes in the pressure of the original fluid in the region. Predetermined volume increments of the measurement fluid are displaced, causing changes in the original fluid pressure in the region which are measured by a pressure transducer. The dispensing arrangement also repetitively dispenses fluid into and out of the region in increments monitored by the pressure transducer.

Abstract: In a fluid flow control system a weight comparator compares the weight of fluid in a reservoir with a weight reference that is programmed to decrease at a desired rate. A fluid flow comparator compares the actual fluid flow rate with a programmed fluid flow rate and operates directly on a flow controller to control fluid flow in the system. The weight comparator operates indirectly on the flow controller by recurringly updating the programmed fluid flow rate so that flow is controlled on a current basis by the fluid flow comparator and on a long-term basis by the weight comparator.

Abstract: The flow regulator device comprises an internally threaded plug, a punch, a blade and a body. The body has a substantially parallelepipedal form defining a "C"-like cross section and a tower portion terminating in an externally threaded cylindrical tract, adapted for threadedly engaging the plug. The punch protrudes from the plug and is adapted for acting on the blade. The blade projects internally from the body and is adapted for exerting force on a pipe wherein the flow rate is to be controlled.
