摘要:
A device and method for improving hydration of a biomaterial includes a syringe having a cavity therein and a distal opening, an end cap, and a wall operatively coupled to the end cap. The end cap has a distal plate with an inlet and is removably attached to the syringe to cover the distal opening. The wall is positioned proximate to the inlet and at least partially defines a volume in fluid communication with the inlet. An orifice extends through the wall and fluidly connects the volume to the cavity. A flow of a liquid component of biomaterial diffuses through the orifice and is introduced into a particulate component of biomaterial. As such, the liquid component of biomaterial hydrates the particulate component of biomaterial.

An applicator for dispensing a fluid for use during a medical procedure includes a dispensing body for containing the fluid. The dispensing body includes a conduit, and a mixing tip operatively connected to the conduit for receiving the fluid from the dispensing body. The mixing tip includes a tip body having an interior passage. The interior passage includes an inlet at a first end fluidly connected to the conduit for receiving the fluid from the conduit and an outlet in a distal wall at a second end opposite to the first end. An insert body is positioned within the interior passage. A first passage is positioned between the insert body and the tip body and fluidly couples the interior passage with the outlet in the distal wall. A mixing chamber is positioned between the insert body and the distal wall. The mixing chamber includes a static mixing element.

Apparatus and methods for dispensing small beads of a viscous, mixed fluid material formed by first and second viscous fluids. The apparatus includes first (62) and second (64) metering rods for moving in a reciprocating manner, such that the first metering rod (62) extends into a first fluid passageway (52), and the second metering rod (64) extends into a second fluid passageway (54). A mixing passage (80) communicates with the first and second fluid passageways to receive the first and second viscous fluids from the first and second fluid passageways. A dispensing passageway (82) is in fluid communication with the mixing passage, and dispenses a small bead of viscous, mixed fluid material formed by the mixed first and second viscous fluids. A control (104) retracts the first and second metering rods to prevent drooling of the viscous, mixed fluid material from the dispensing passageway after a dispensing cycle.

Systems, feeder devices and methods for moving particulate hot melt adhesive from an adhesive supply (10) to an adhesive melter (12). A feeder device (14) includes a body having an inlet (21) and an outlet (42), and an interior communicating with the inlet (21) and the outlet (42). The inlet (21) is configured to receive particulate hot melt adhesive from an outlet of the adhesive supply (10), and the outlet (42) is configured to provide particulate hot melt adhesive to an inlet of the adhesive melter (12). The feeder device (14) further includes a mechanical agitator (50) positioned in the interior for urging the particulate hot melt adhesive in a flow direction toward the outlet (42).
摘要:
A melter (12) includes a heater unit (20) for melting adhesive, a reservoir (22) for receiving melted adhesive from the heater unit, and a pump (56) in fluid communication with the reservoir and located within a heated housing (252). The heated housing heats the pump during startup and regular operation of the adhesive melter, thereby reducing delays in operation caused by slow warming of adhesive within the pump. The heated housing may be a manifold (54) in fluid communication with the reservoir and with fluid outlets in some embodiments, but the heated housing may also be a separate heat block (352). In either type of embodiment, the pump is configured to be inserted cartridge-style into the heated housing and held in position using a single locking fastener (284).
摘要:
A fluid dispenser and a method for using the fluid dispenser with a syringe barrel holding a fluid including a distribution of composite materials. The fluid dispenser (10) includes a dispensing valve (22) operable to dispense the fluid and a coupling for fluidly connecting the syringe barrel (12) to the dispensing valve (22). The fluid dispenser (10) also includes a support frame (24) for rotatably supporting the syringe barrel (12) and a motorized drive unit (26) configured to rotate the syringe barrel (12). The syringe barrel (12) rotates via the motorized drive unit (26) to distribute the composite materials uniformly within the fluid for dispensing the fluid.
摘要:
A dispenser (120) for dispensing liquid material while attenuating the liquid material or controlling the pattern of the liquid material with process air has a plurality of process air passages for providing process air to one or more liquid dispensing modules or nozzles. The flow rate and/or flow rate of process air to one or more of the modules or nozzles may be separately controlled to be different from the flow rate provided to other modules or nozzles on the dispenser (120). Accordingly, the flow rate provided to each module or nozzle can be optimized to accommodate a particular dispensing nozzle or die.
