Abstract: An adapter tube is provided with a pivotally flexible swivel joint providing an aerosol-conducting airway for use with an inhalation mask with a nebulizer.

Abstract: Cell carrier structures using dynamic flow of cell bearing, washing, or nourishing fluid, from an input reservoir region to an output reservoir region. A common feature of the several structures by which this can be achieved is the presence of channels generally having low height or other cross section, such that the cell bearing fluid readily traverses these channels by capillary action. Optional pumping assistance can also be provided. The capture wells or traps are disposed generally along the length of these channels such that the cells have multiple chances of being captured in a trap or well. The traps or wells are structured such that only a single cell can be trapped in each well or trap, and the disposition of the wells or traps as appendages to the fluid flow channels facilitates the washing or nourishing of the cells while their proliferation or development is being observed.

Abstract: There are provided cell carrier devices for use in cell observation systems, enabling determination of the location of the region under observation by virtue of coding information present in the field of view of the viewing device, even at high magnification. Other embodiments are also disclosed.

Abstract: A disposable sterile handle cover uses a flexible bag, a portion of the open side of which is held snugly by a retaining ring to the inside of a conical skirt. A first set of spikes include variable length spikes protruding from the inner wall, to secure the bag against the handle. A second set of spikes protrude inwardly from the retaining ring and promote stretching and orderly application of the to the handle.

Abstract: A pneumatic nebulizer for the delivery of medications that produces aerosol mist in a downward direction. A gas inlet introduces a high velocity gas that passes through a venturi orifice producing a venture effect. A liquid stored in a reservoir is drawn into the orifice, atomizing forming droplets. The droplets are further atomized by hitting a baffle. The mist formed substantially circumscribes the baffle.

Abstract: The present invention is an aerosol inhalation interface, and a method for its use. The device delivers a flow of aerosol medication to a patient breathing tidally by creating a medication rich environment proximal to the nose and mouth of the patient, while the patient is in a reclining position. The device, which is suspended above the patient's nose and mouth, is comprised of an aerosol generator, which generates medicated particles; a containment region, into which the generator discharges the medicated particles; a downwardly projecting outlet sleeve, which is connected to the containment region and channels the particles from the containment region to create a medication rich environment proximal to the nose and mouth of the patient; and an air movement deflector, which inhibits the dispersion of the particles and disturbance of the medication rich environment.

Abstract: Disclosed is a nebulizer having a downwardly facing aerosol outlet that is structurally configured so as to produce aerosol mist in a downward direction and that delivers a downwardly directed flow of medicated aerosol mist for a period of time. That is to say, a downdraft nebulizer.

Abstract: A head rest support mechanism for a vehicle seat, the head rest being fitted with at least one support rod having a plurality of notches and being supported by the seat back and adapted for vertical adjustment with respect thereto, the support mechanism further including a guiding member fixed to the seat back and comprising a bore slidingly and snugly supporting the support rod. There is a latching spring supported by the guiding member and having one end fixed to the guiding member, another end projecting from the guiding member, and an intermediate, looped, notch engaging portion being normally biased to engage a portion of a notch. The support rod comprises a plurality of notches each lying in a plane which is perpendicular to a longitudinal axis of the rod and a normal of the plane is not perpendicular to the longitudinal axis.

Abstract: An over filling interdiction valve, fitted within a fluid tank, the valve comprising a housing furnished with a first fluid inlet at a bottom end thereof and a first fluid outlet at top end thereof, a float member located within the housing and being displaceable along its longitudinal axis between the first inlet and the first outlet. The float member comprises at its bottom end a second fluid inlet and near its top end a second fluid outlet. Sealing means are associated at a top end of the float member for sealing the first fluid outlet and biasing means are provided within the housing for biasing the float member towards the first fluid outlet.

Abstract: A roll over vent valve comprising:a housing having a fluid inlet and a fluid outlet, the latter comprising a substantially elongated slit-like outlet aperture of the housing bounded by a valve seating. There is furthermore provided a float member located in the housing and axially displaceable within the housing between the inlet and the outlet; an elongated flexible closure membrane strip anchored at one end thereof to an end of the float member adjacent the outlet and at a portion thereof offset with respect to the outlet; spring biassing means located within the housing and bearing on the float member so as to spring bias it in the direction of the outlet; whereby the spring biassing together with buoyancy forces acting on the float member tend to press the membrane strip into sealing engagement with the outlet aperture whilst gravity forces acting on the float member tend to displace the float member away from the outlet so as to progressively detach the strip from sealing engagement with the outlet.
