  • Patent number: 8162887
    Abstract: An injection device comprises a syringe extendible against a spring bias from a retracted position in a housing to a projecting injecting position. A spring biased plunger has collapsible elbows which, when the plunger is released, initially engage the end of the syringe to drive it to the projecting position, whereupon arresting of the syringe movement causes the elbows to collapse inside the syringe to allow the plunger to engage and drive the bung.
    Type: Grant

  • Publication number: 20080027300
    Abstract: An oximetry probe assembly includes fluid seal assembly taking the form of a manually actuated plunger which moves relative to a barrel having a seal placed therein. Depression of the plunger causes the seal to be deformed so as to permit insertion of an oximetry probe through the seal and advancement towards a central venous catheter. When the plunger is released, the seal is compressed against the barrel and the sheath of the oximetry probe to thereby form a fluid-tight seal. The plunger and barrel are preferably configured as a one-handed grasping assembly whereby the user may hold the plunger and barrel with one hand, press the plunger with the thumb, and advance the oximetry probe through the fluid seal assembly with the other hand.

  • Publication number: 20060259004
    Abstract: A method and system for handling hazardous materials contained in a vial includes an isolation enclosure having an opening selectively sealable about the vial, a bag body portion, and a cap portion. A latching extraction element is attached to the cap portion and has a preceding engaging member to secure the vial to the isolation enclosure, an extraction member to be inserted into the vial and remove material therefrom, and a primary engaging member to secure the vial to the extraction member. A valve is mounted outside the isolation enclosure and controls the flow of fluid from the vial. An adaptor having a reseal member permits flow when coupled to the valve and restricts flow when uncoupled from the valve. Once uncoupled, the adaptor is removably associated with a second valve located remotely from the isolation enclosure, allowing fluid to pass into the second valve.

  • Patent number: 4568366
    Abstract: An in-line set filter for parenteral solution sets and the like which comprises a tubular housing having first and second ends. A bundle of filter tubes is positioned within the housing, the filter tubes preferably being folded so that all ends of the filter tubes occupy a single zone in communication with the first housing end. The zone is filled with potting compound with the filter tube ends communicating through the potting compound and open to the exterior. A flow access port is laterally positioned in a side wall between the second end and the potting compound but closer to the potting compound. The second end defines an open aperture occluded by a porous hydrophobic filter to permit venting while preventing loss of aqueous liquid.
