Abstract:
An assembly for a fluid transfer system includes: a connector (106) having a proximal end (112) and an opposite distal end (114) connected by an inner passage (116); and a container (110) having an internal fluid reservoir (124). The connector is coupled to the internal fluid reservoir of the container to form a series fluid connection between the inner passage and the internal fluid reservoir, and the connector and the container are made of a biodegradable material.
Abstract:
A coupling device includes a main body (220) defining a fluid flow passage (230), and a valve member (240)moveable between an unconnected state and a connected state. The coupling device also includes a magnet (265) coupled to the valve member, and a sensor (275) coupled to the main body, the sensor being configured to sense a change in a magnetic flux of the magnet as the valve member moves between the unconnected state and the connected state to determine a connection state of the coupling device.
Abstract:
A coupler (211) includes a main body (210) including a first end (212) and a second end (214), and a flow passage (216) between the first and second ends to allow fluid flow therethrough. The coupler can also include a frame member (240), and a radio frequency identification tag (230) coupled to the frame member (240). The frame member (240) is configured to be molded into the main body (210) so that the radio frequency identification tag (230) is incorporated into the main body (210).
Abstract:
An antenna for radio frequency communication, such as for a reader circuit that is configured to be coupled to a coupler of a system for controlling fluid dispensing. The antenna can include a printed circuit board with an aperture and a plurality of windings disposed circumferentially about the aperture. The antenna can also include a U-shaped core having first and second legs coupled by a third leg, the third leg being coupled to the printed circuit board, and the first and second legs extending generally parallel with respect to opposite sides of the printed circuit board over the plurality of windings.
Abstract:
A connector apparatus designed for use in a bioprocessing assembly, and a method for coupling a piece of bioprocessing equipment to a media source in a sterilized environment. The connector apparatus includes a coupler including an end and at least one outlet, and a connector valve connectable at a first end to a fluid source, the connector valve including a valve member, the valve member being partially disposed within the coupler. The connector apparatus further includes a flow passage being actuatable from a closed configuration to an open configuration when the coupler and the connector valve are engaged, as well as being actuatable from an open configuration to a closed configuration. A clip member attached to the coupler allows the valve member to be moved from the closed configuration to the open configuration, and from the open configuration to the closed configuration.
Abstract:
A closure valve used in a fluid dispensing assembly. The closure valve contains a housing, poppet, sleeve, and a biasing member. The closure valve provides simplified sealing structures for preventing product leakage and spill. The sealing structures being integrally molded sealing structures.
Abstract:
A high flow low spill quick coupling valve assembly (40) is used to connect to pressurized large diameter fluid lines. The valve assembly includes a female coupling (44) and a male coupling (42), each of which defines a fluid passageway. Both male and female coupling valves are fluid pressure balanced to minimize the connecting force used to lock the valve assembly and the disconnecting force used to unlock the valve assembly. The fluid spillage or leakage is minimized. All spring members (80, 104) in the valve assembly are isolated from the fluid passageways. The valve assembly also includes a plurality of static seals between inner and outer bodies of the male coupling and between an inner body and a fluid conduit adaptor of the female coupling, or between the end surfaces of the inner and outer bodies of the male coupling and between the end surfaces of the inner body and the fluid conduit adaptor of the female coupling. The static seals are deformed, once the coupling valve assembly is assembled, to form a seal. Preferably, the entire valve assembly is made of plastic material except for the spring members which are disposed outside the fluid passageways.
Abstract:
A shutoff valve (26) including a plunger (28) slidably mounted in a housing (30). The plunger (28) being slidable between an open and a closed position. The plunger (28) having a front end and a back end and defining a path flow of fluid therethrough. A back end (32) of the plunger (28) having inclined surfaces (50). Projections (34) extend from the back end (32) of the housing (30) and cooperate with the inclined surfaces (50) to bias the plunger (20) into the closed position.
Abstract:
This document describes fluid handling couplings. For example, this document describes fluid handling couplings that include manually openable valves and that are configured for aseptic fluid handling usage. In some embodiments, the valves are manually openable by rotation of a collar of the fluid handling couplings.
