Abstract: The safety device of the instant invention is equipped with a fluid absorbable material at the portion of the sheath that meets the tip portion of the needle so that, as the sheath is pivoted to a position in substantial alignment with the needle, whatever fluid that has been collected at the needle is absorbed before the needle is fixedly retained by a locking mechanism, either integrated within the needle sheath or to the base and lower portion of the needle sheath, to thereby prevent splattering or aerosolization of contaminated fluid into the environment.

Abstract: A safety device to be used with a winged intravenous infusion assembly has a base that is adaptable to fit over the body of the infusion assembly. Attached to the base is a housing that is pivotable to a position in substantial alignment along the longitudinal axis of the base for enveloping a needle extending from the infusion assembly when the housing is pivoted to the alignment position. Locking mechanisms may be provided in the housing for preventing movement of the housing relative to the needle once the needle is enveloped by the housing. The base can be configured to include a tubular portion that slidably fits over the front end of the infusion assembly or a pair of arms that intimately embrace the body of the infusion assembly. Alternatively, the safety device could be cast from the same mold as the IV infusion assembly so that the molded IV infusion assembly could have directly extending therefrom the safety device.

Abstract: The temperature regulating device of the instant invention accurately regulates the temperature of a fluid to be sent through a conduit for either warming or cooling an infusate that is to be provided to a patient. The heater/cooler that is used for regulating the temperature of the fluid, and the fluid itself, are continuously monitored by a number of sensors, which provide feedback signals to a processor controller, to ensure that the temperature of the fluid is maintained at a desired temperature. The fluid is circulated by a pump which operation is also continuously monitored. A special connector assembly provides the inlet/outlet connection between the device and the fluid conduit. The connector assembly is constructed such that the system would operate only when the connector of the fluid conduit is correctly mated thereto.

Abstract: A hydrophobic electrostatic breathing filter is fabricated by applying a thin layer of adhesive to the pinch ring of a patient side filter housing portion. A hydrophobic membrane is positioned over the adhesively coated pinch ring to effect a hermetic seal between the pinch ring and membrane using the adhesive interface. Electrostatic filter media and scrim are positioned adjacent the pinch ring of a machine side filter housing portion, and the patient and machine side portions of the housing are then welded together to hold the electrostatic filter media/scrim in place adjacent the hermetically sealed hydrophobic membrane by a mechanical clamping force exerted by the pinch rings. The resultant filter includes a hydrophobic membrane which is hermetically sealed across the patient side of the filter housing, and an electrostatic filter media/scrim element which is independent of the hydrophobic membrane and which is mechanically held in place adjacent the hydrophobic membrane.

Abstract: An apparatus for performing a variety of fast and slow operations including mounting operations upon workpieces affixed to workpiece carriers in which the slow operations are carried out at one station and the fast operations are carried out at another. The linear transfer device of the fast station operates at a stroke rate which is greater by a whole number than the stroke rate at the slow operation station, the workpiece carriers are fed in groups equal to this whole number to the slow operation units simultaneously and the slow operation units perform the same slow operation at each of a number of these units equal to that whole number.

Abstract: An assembly machine has a frame defining at least one work station, a transfer mechanism for feeding a succession of workpieces one at a time through the station, and at least one tool at the station movable between an operative position engageable with the workpiece in the station and a retracted position out of engagement with the workpiece in the station. A push-pull operating element has an outer end connected to the tool and an inner end connected to a cam carried on an output of a drive mounted on the frame for displacing the tool between its positions synchronously with feeding of the workpieces through the station. A pneumatic spring mounted on the frame is braced against the tool and has a compartment pressurizable to urge the tool into the operative position. The back compartment is continuously pressurized with a gas under a generally constant pressure.

A blocking element at the holding station can move between a position preventing downstream movement of the holders past the holding station and a position permitting such downstream movement.

Abstract: A needle protection safety package, instead of being enclosed in a pouch or other containment wrappings, has fitted thereto at respective ends thereof caps or sheaths so that both the needle and the end to which a syringe is adapted to mate remain enclosed and sterile. Such an arrangement enables easy transport of the safety needle package and provides convenience for the user at the same time. The safety package is further designed to prevent burring of the tip of the needle as the cap or sheath is removed from the needle portion of the package. A further embodiment of the safety package incorporates a locking mechanism which prevents contact between the needle and the housing as the housing is pivoted to envelop the needle after use.
