Abstract:
A fluid conduit includes a hose and a fitting. The hose has a terminal end having a first portion along which an outer layer is laminated to an inner layer and a second portion along which the inner layer extends from the outer layer. The fitting includes a receiving portion and a coupling portion. The receiving portion has a first inner surface defining a first lumen portion, and is configured to receive the first portion of the terminal end, and for crimping to the hose. The coupling portion has a second inner surface defining a second lumen portion for receiving the second portion of the terminal end. The first lumen portion and the second lumen portion are in fluid communication with each other.
Abstract:
A sterile connector assembly for mounting on a fluid system includes a first connector and a second connector. The first connector includes a stem defining a fluid passage therethrough, a first housing surrounding the stem and defining a first aperture, and a first valve disposed over the first aperture. The second connector includes a second housing configured to matingly engage the first housing. The second housing defines a second aperture and defines a seal structure. The seal structure is configured to engage the stem. The second connector also includes a second valve disposed over the second aperture. The second valve is configured to engage the first valve when the first housing engages the second housing.
Abstract:
A flanged joint system connects two pipes disposed along a common axis. A flange having a mating surface terminates each pipe. A gasket assembly comprising an outer annular, substantially rigid retaining ring and a peripheral alignment rim, an inner deformable annular sealing member is interposed between the mating surfaces of the flanges. The flanges and gasket assembly are aligned in mutually coaxial relationship by receipt of the flanges within the alignment rim. The flanges are clamped together with their mating surfaces in axially aligned, facing relationship. The retaining ring limits the impingement of the flanges and prevents overcompression of the deformable material. The joint is reliable and durable, and permits aseptic processing conditions to be maintained. Servicing and gasket replacement are readily accomplished.
Abstract:
An aseptic coupling device includes a first state in which fluid does not flow through the aseptic coupling device. In addition, the aseptic coupling device includes a second state in which fluid does flow through the aseptic coupling device. The aseptic coupling device can be moved from first, second, and third states to control the flow of fluid through the aseptic coupling device.
Abstract:
The disclosure is directed to a fluid conduit including a hose and a fitting. The hose has a terminal end having a first portion along which an outer layer is laminated to an inner layer and a second portion along which the inner layer extends from the outer layer. The fitting includes a receiving portion and a coupling portion. The receiving portion has a first inner surface defining a first lumen portion, and is configured to receive the first portion of the terminal end, and for crimping to the hose. The coupling portion has a second inner surface defining a second lumen portion for receiving the second portion of the terminal end. The first lumen portion and the second lumen portion are in fluid communication with each other.
Abstract:
A hose coupler that allows flexible hosing to be quickly and easily mated to various pieces of equipment. The hose coupler includes a stem that fits snugly into the end of the hose, a compression sleeve, and a collar that forces the compression sleeve against the hose, thereby reversibly fastening the stem within the end of the hose.
Abstract:
A high gloss sheet or pipes or tubes or connector joints prepared from a metallocene-produced polyethylene having a density of from 0.910 g/cm3 up to 0.966 g/cm3, or up to homopymer densities, and a melt index MI2 of from 0.01 to 20 g/10 min.
Abstract translation:由金属茂生产的聚乙烯制备的高光泽片材或管子或连接器接头,其密度为0.910g / cm 3至0.966g / cm 3,或高达同色差密度,熔体指数 MI2为0.01〜20g / 10min。
Abstract:
An apparatus for establishing aseptic/sterile connections including a substantially flexible, substantially transparent sterile barrier enclosing a terminal end of a conduit and a resilient, deformable support card which further includes an adhesive perimeter covered by a release paper and a rolling membrane with a continuous, removable, yieldable, flexible strip material. A portion of the rolling membrane is removably adhered to the support card and overlies the end of the conduit. A force applied to the free end of the rolling membrane withdraws the entire rolling membrane to expose the end of the conduit so that an aseptic/sterile connection is achieved by adhering opposing support cards together, removing the rolling membrane to create a sterile corridor between a first sterile barrier and a second sterile barrier, and mating the terminal end of a first conduit and a second conduit together.
Abstract:
A connector assembly and a fluid system or device comprise a connector assembly which includes first and second fittings, each fitting having an aperture, and a stem disposed in the aperture of the first fitting. In various embodiments of the invention, the connector assembly may further comprise a socket cooperatively arranged with one of the first and second fittings, at least one resilient sealing member, a sealing layer joined to the socket or covering the resilient sealing member, and/or a deformable locking device. A method for making a connection includes mating a first fitting having an aperture and a second fitting having an aperture without fluid within the first and second fittings, establishing a fluid flowpath through the first and second fittings by advancing a stem having a head through the aperture of the first fitting into the aperture of the second fitting, and establishing fluid flow through the first and second fittings by opening a fluid blocking mechanism.
Abstract:
A connector assembly includes first and second fittings including first and second membrane assemblies, respectively, and a stem member. A fluid delivery system includes a connector assembly, a container for holding fluids and tubing which couples the container to one of the first and second fittings. A method for making a contaminant-free connection comprises mating first and second fittings, and establishing a fluid flow path through the first and second fittings. The systems, assemblies and methods according to the invention may be used, for example, to handle a biological fluid while maintaining the fluid free of viable contaminating microorganisms or preserving its sterility.
