20080208159 | FLUID CONTAINER WITH ACCESS PORT AND SAFETY CAP - An access port for a medical fluid container is provided and in one embodiment includes a shell and a perforator located within the shell, the perforator including an end configured to pierce a medical fluid container. The access port also includes a safety cap, the safety cap initially preventing the perforator from rotating relative to the plane of the container or piercing the container film. The safety cap is manually removable to enable the perforator to pierce the medical fluid container. The shell includes a pair of hinged moving arms and members hinged to the arms. The members push the perforator towards the medical fluid container when the arms are pushed downwardly. | 08-28-2008 |
20090270832 | NEEDLELESS PORT ASSEMBLY FOR A CONTAINER - A needleless access port is assembled from parts sealed to a flexible container, such as a container for intravenous infusion, parenteral nutrition or transfusion. The port includes a lower housing for sealing to the container, the lower housing having an upright tower for mounting an upper housing. The upper housing has at least one connector or valve and a sleeve for mounting to the tower. The sleeve includes connectors so the upper housing can be mounted in a first, upper resting position, and a second lower, active position, for adding liquid to the container or for removing liquid from the container. Even after assembly to a container, the upper housing may be removed and the lower housing may be used instead with a standard IV spike set. | 10-29-2009 |
20100004619 | PORT ASSEMBLY FOR USE WITH NEEDLELESS CONNECTOR - A port assembly includes a valve housing with an inlet opening, a valve disposed in the valve housing to control access through the inlet opening, and a base joined to the valve housing and having a bore therethrough. The bore has a closed end defined by a frangible barrier, and a pushrod is disposed in the bore between the valve and the frangible barrier, axial movement of the pushrod causing rupture of the frangible barrier. The port assembly may be used in a fluid container that includes a receptacle for retaining a fluid, and at least one conduit in communication with the receptacle. The at least one conduit is defined, at least in part, by a port assembly. | 01-07-2010 |
20100049160 | PORT ASSEMBLY FOR USE WITH NEEDLELESS CONNECTOR - A port assembly includes a housing with an opening and a bore therethrough, a slit septum disposed in the bore to control access through the opening, a base joined to the housing and having a membrane attached thereto, a perforator having a first end abutting the slit septum and a second end aligned with the membrane, and a resilient member disposed between the perforator and the base. The port assembly may be used in a fluid container that includes a receptacle for retaining a fluid, and at least one conduit in communication with the receptacle. The at least one conduit may be defined, at least in part, by the port assembly. | 02-25-2010 |
20100133278 | CONTAINERS AND METHODS FOR MANUFACTURING SAME - A container is provided comprising a body defined, at least in part, by a film, the body including at least one side seal, at least two chambers separated, at least in part, by a peelable seal, and the film including a sealant layer having a bimodal thermal behavior such that the side seal is a permanent seal and the peelable seal can, at least in part, be separated. | 06-03-2010 |

20110100631 | FLOODING FLUID AND ENHANCING OIL RECOVERY METHOD - The invention relates to an enhancing oil recovery method by injecting into a subterranean oil formation an aqueous flooding fluid comprising at least one injecting galactomannan polymer substituted by at least one sulfonation agent. The invention also relates to an flooding fluid having better injectivity properties than existing flooding fluids. | 05-05-2011 |
20110127196 | Viscous Hydrocarbon Treatment Method by In-situ Asphaltene Inerting - The invention concerns a method for treating viscous hydrocarbon containing asphaltenes, which consists in performing the following steps: precipitating at least part of the asphaltenes by adding into the hydrocarbon an appropriate solvent; adding into the hydrocarbon polymerization products adapted to encapsulate the precipitated asphaltenes to inert same. | 06-02-2011 |
20130213650 | OPTIMIZED CHEMICAL ENHANCED RECOVERY METHOD - The invention relates to an enhanced recovery method that optimizes the stages of pumping, transport and surface treatment of the production effluent. The method of the invention comprises the following stages:
