The cover includes a plate for overlying the web and is formed with a plurality of nesting rings arranged in the predetermined spaced relationship for centering over the respective sinks and spaced a predetermined distance therefrom. The applicator includes a finger grip knob formed with a downwardly facing nesting shoulder for nesting on the respective nesting rings and further includes an elongated pick formed on its bottom end with a penetration point of sufficient length to, when the nesting shoulder is nested on one of the respective nesting rings, project into the respective sink to be immersed in the respective allergen.

Disposable allergen container and pick apparatus

A tubular fitment capable of establishing a fluid tight passage defining a connection between first and second confined space defining means, with the tubular fitting when in a first condition permitting the second confined space defining means and a second portion of the tubular fitment to be rotated relative to a first portion of the tubular fitment and the first confined space defining means, and the tubular fitment when in a second condition locking the first and second portions thereof in fixed positions relative to one another.

Tubular fitment

A device which in combination with a vacuum creating source and a pressurized source of a first liquid, permits all or a portion of a number of second liquids to be selectively filtered either singly or concurrently, and the particulates resulting from the filtering operation washed separately with the first liquid prior to the particulates being removed from the device. The device is of such structure that a number thereof may be connected by tubular means end-to-end to permit the separate filtering of any desired number of second liquids and the subsequent washing of the particulates from the second liquids with a first liquid from a pressurized source thereof.

Filtering and particulate washing device

A tray having a number of spaced, individually spaced cavities extending downwardly therein in which tubular containers are removably disposed that contain biological active liquids. The containers have open tops in which resilient stoppers are sealingly disposed. Each stopper has a longitudinal bore therein that terminates on the upper end in a projecting bubble. Each bubble may be severed from the stopper with which it is associated by cutting transversely through the base of the bubble with a sharp sterile instrument such as a razor blade or the like. Immediately upon the bubble being severed, an elongate sterile applicator is removably and sealingly disposed in the bore associated with that bubble The applicator includes a handle from which a tapered shank projects to terminate in a flat first end from which a number of spaced needle like projections extend, with the projections being of a length that is the depth that is desired to have same penetrate into the skin. When the applicator is slidably removed from the bore in a stopper, a predetermined quantity of the biological active liquid will adhere. When the projections are forced into the skin of a patient the adhering liquid is transferred to the patient. The first end of the shank acts as a stop by contact with the skin of the patient. The applicator assures not only that a predetermined amount of liquid will be injected into a patient, but limits the depth to which such injection will be made. The applicator after use is discarded, and a new sterile applicator is inserted in the bore of a stopper to seal the liquid in the container associated with that stopper from contact with the ambient atmosphere.

Antigen injection assembly

A filter holding assembly capable of being used to filter pressurized fluid from a source of the latter, with the assembly capable of being dismantled without the use of hand tools to occupy a minimum of space, and the assembly likewise capable of being transformed without the use of hand tools to a unit in which first and second mating plates support a large diameter filter membrane in a position to be subjected to the pressurized fluid. Particulates in the fluid above a predetermined size are deposited on the membrane, with the balance of the fluid discharging as a filtrate from the assembly. The first and second plates when in mating engagement define a centered confined space in which the membrane and a supporting screen are disposed, and the membrane having the peripheral edge portion thereof in sealing contact with a compressed resilient ring to prevent the pressurized fluid in the centered confined space by-passing the membrane. The filter assembly is particularly adapted for use with a second filter assembly that is supported therefrom, with the large diameter first membrane effecting a primary filtration in which particulates above a predetermined size are removed from the fluid, and the resulting filtrate when subjected to a finer filtration by the second assembly to remove particulates above a predetermined size that have passed through the first membrane.

Filter holding assembly

An elongate, portable, hand-operated assembly adapted to create either a negative or positive pressure within the interior thereof, with the device being capable of having a hypodermic needle removably mounted on either end thereof. The assembly may be actuated to create a negative pressure to draw a liquid that may contain entrained particles of solid material into the interior of the assembly. After the assembly has introduced liquid therein in a desired volume, it may subject the liquid to positive pressure to separate particles of solid material such as protein, bacteria and viruses from the liquid. Liquid free of solid particles, may be discharged from the assembly through a hypodermic needle that is removably secured to the assembly. A magnetically attractable body may rest on the filter within the interior of the assembly. When that body is subjected to a rotating magnetic field, the body moves concurrently with the field, and in so moving, the body removes caked, solid particles from the filter to facilitate the flow of liquid through the latter.
