摘要:
A single-use fluid dispenser cartridge, installable or installed into a host fluid dispensing apparatus, is described. The single-use fluid dispenser cartridge is provided with a fluid reservoir, a fill tube assembly, and means for controlling pressure within the cartridge by gating gas into or out of the reservoir and/or the fill tube assembly. The gas gating mean enables, in certain embodiments, use of a fluid reservoir that is "substantially rigid".

A fluid sampling device having a configuration suitable for "single-use disposability while enabling good aseptic sampling. The fluid sampling device comprising a port insert (10) suitable for installation into a port provided in a fluid receptacle, said port insert (10) comprising a body (20) having one or a plurality of shafts (26) therethrough, and sample gating means for selectively opening and closing any of said shaft(s) (26) to enable the flow of fluid through the body (20) through a respective one of the shaft(s) (26) in an "open" position, but not in a "closed" position. The individual shaft(s) (26) are configured to be communicated with a respective sample container via a respective conduit (120).

摘要:
A method for over-molding a tubular filter element 16, at least at one end 16b thereof, with a thermoplastic end cap 12. The over-molding method can be used to manufacture easily and cost-effectively a filter cartridge, of good durability, from an unprecedented range of polymeric materials and components. The thermoplastic over-molding method does not require pre-lamination of said end 16b, and can be performed at temperatures and pressures that do not result in undesirable morphological changes in the tubular filtration medium. Exemplary filter cartridges made through the over-molding method comprise a tubular filtration medium interposed between thermoplastic end caps, the thermoplastic material of the end caps infiltrating the tubular filtration medium, thereby creating mechanical interlock zones at the ends thereof.

A fluid sampling device comprising a port insert (10) having a plurality of shafts (26), each of the plurality of shafts (26) having an inlet opening (24a-24d) an an outlet opening for allowing fluid to flow therethrough, and a sample gating means (36) having a passage (38) for allowing fluid to flow therethrough. The port insert (10) and the sample gating means (36) are rotatable with respect to each other such that the passage (38) of the sample gating means (36) can be sequentially aligned with each of the plurality of shafts (26) of the port insert (10).

A single-use fluid dispenser cartridge, installable or installed into a host fluid dispensing apparatus, is described. The singfe-use fluid dispenser cartridge is provided with a fluid reservoir and a fill tube assembly with bladder means for controlling pressure within the cartridge by accommodating the movement of gas into and out of the fill tube assembly.

A single-use fluid dispenser cartridge, installable or installed into a host fluid dispensing apparatus, is described. The single-use fluid dispenser cartridge is provided with a fluid reservoir, a fill tube assembly connected to said fluid reservoir and bladder means being disposed at an end of said fill tube assembly opposite said connection thereof to said fluid reservoir for controlling pressure within the cartridge by accommodating the movement of gas into and out of the fill tube assembly.
