Abstract: The subject invention is an implant for relieving abnormally high intraocular pressures with the anterior chamber of an eyeball which is associated with the disease called glaucoma. The implant includes a base plate which is formed of a thin, flexible, preferably rubber material such as silicone rubber. Mounted on the base plate is a housing with the housing including an internal chamber. The housing has an open front end covered by a canopy which is mounted on the base plate. The rear end of the housing is attached to a tube. Aqueous humor is to be conducted through the tube, through the porous block and then through the access opening into the ambient. The housing is mounted within a mounting pocket formed within the base plate.

Abstract: A flow control valve for a flexible walled tubing to control and regulate the rate of flow of a fluid through the tubing which comprises a pair of movable fingers which are pressed against a thermally deformed flaccid section of the tubing to vary the cross-sectional size of the bore within the tubing thereby controlling the volume of flow of the fluid through the tubing. This flow control valve is particularly useful in administering liquids for intravenous feeding and other medical purposes.

Abstract: The surgical stylet formed as an elongated, thin member which includes a metallic core which is capable of being bent and remain stationary in any particular desired configuration. A rigid plastic is extruded over the core with the fore end of the core being exposed. The fore end of the core includes an enlarged section. The outermost tip of the fore end is smoothly contoured. A second exterior covering is located about the fore end and extends a short distance beyond the tip. The second exterior covering is formed of a plastic substantially softer than the first covering. The second exterior covering is secured to the fore end with the enlarged section of the fore end to facilitate this securement. The thickness of both the first and second exterior coverings may be such so as to permit the including of longitudinal passageways through the coverings. Within each passageway there is to be located a thin wire member which is capable of being manually moved within the passageway.

Abstract: In combination with an instrument for taking tissue specimens which comprises a pair of movable jaws. One jaw is capable of being located within a cavity of the other jaw. The tissue specimen is to be located within the cavity. Also located within the cavity is a biasing means in the form of a leaf spring which is to exert a continuous bias upon the tissue specimen and, upon opening of the jaws, the tissue specimen is automatically moved to the upper end of the cavity to facilitate its removal therefrom.

Abstract: A disposable diagnostic swab assembly which takes the form of an elongated tubular member having an internal chamber which is permanently closed at the inner end and is openable at the outer end by the removal of a cap. A culture medium containing breakable pouch is located within the internal chamber at the inner end. An elongated swab is attached to the cap with the tip of the swab being located directly adjacent the pouch. The pouch is to be breakable by applying localized pressure upon the tubular member in the area of the pouch which causes the culture medium to saturate the tip of the swab. A glass slide section may also be attached to the tubular member with access to the glass slide being permitted to facilitate usage thereof.

Abstract: The drug detection device which is composed of a pair of members interconnected together to form an internal enclosed chamber. An elongated swab having an absorbent tip is located within the internal enclosed chamber. One of the members of the housing has attached a pair of separate compartments which are interconnected by a frangible seal and further being interconnected to the internal chamber by a frangible seal. Within each of these compartments there is to be located a different substance and upon breaking of the frangible seal between the compartments, the substances within these compartments are to be intermixed. Upon the breaking of the frangible seal to the internal chamber, the tip of the swab will then become in contact with the intermixed substances. The other member of the housing has attached at its closed end a third compartment and within this third compartment is to be located a third substance.

Abstract: A sponge disposal tray for use in conjunction with medical surgical procedures which comprises a plurality of containers which are normally closed by a thin sheet material access cover. The access cover includes a plurality of access openings with a single access opening connecting with a single container. Each access opening comprises a pair of crossed slits which is normally closed but openable upon insertion of a single sponge into a container. A removable sealing cover is to be adhesively secured to the frame and to completely cover said access cover. The frame may include a sponge storage compartment. Also the bottom surface of each of the containers may include an adhesive layer to facilitate frictional connection of the tray to a supportive surface.
