Abstract: The present invention relates to an improved test composition for the diagnosis of gastric ulcers, duodenal ulcers, gastritis, gastric lymphoma and gastric carcinoma by the detection of the bacteria Helicobacter pylori and the enzyme catalase associated with such conditions. The new test composition differs from the prior art agar compositions in being an aqueous solution containing hydrogen peroxide, urea, monobasic sodium phosphate and bromthymol blue as an indicator, and in being far more rapid than the prior art test compositions.

Abstract: A molded pick for handling biopsy specimens which includes an elongated shaft having a tapered blunt short barb at one end and a forked device at the opposite end of the shaft, the forked device having a blunt spatula prong as one fork and a sharp tapered point as the other fork.

Abstract: A test kit for the rapid detection of the bacteria Helicobacter pylori in gastric biopsy tissue to diagnose gastric disease is described which includes a chemical test composition for the bacteria, a tray-like means including means to visibly display the test composition, means to handle a biopsy specimen and insert it in the test composition, and indicia to determine the results of the test.

Abstract: A combination plastic relatively rigid bite block and soft nasal cannula intended for one-time use for supplying oxygen to a patient's nostrils during an endoscopic procedure. The cannula is fixed into the bite block by an integral clip portion of the cannula extending downwardly from a manifold portion and adhered to the bite block. Flexible nasal prongs extend upwardly from the manifold into the patient's nostrils to supply supplementary gas separately from air breathed through the patient's mouth.

Abstract: An improved test composition for the diagnosis of gastric disease by detecting the presence of urease associated with H. pylori in a biopsy specimen is described in which the hydrolysis of urea by urease is detected by a combination of at least two dye indicators showing a color change and a positive result at an acid pH, in which the positive color is distinctive from the color of the biopsy specimen, and in which most positive results occur in 2-10 minutes and all occur in no more than 4 hours. Specific compositions are disclosed.

Abstract: A manually compressible reservoir, such as a rubber bulb is provided in which a liquid medication is maintained and from which an outlet conduit extends to a selected body part. The prosthesis includes a piston for storing separately from the reservoir a predetermined dose of medication and which piston is responsive to the manual compression of the reservoir to discharge the predetermined dose and on release to automatically cause the medication to flow from the reservoir to restore a predetermined dose so that repeated operation and delivery of medication is possible.

Abstract: Involved is a device, noteworthy by its compact construction, portability and use of a cooperating pair of constant torque springs to dispense liquid under a uniform force, in which any binding in the slide that is urged through movement by the torque springs is obviated, so that the slide tracks properly during liquid-dispensing service of the device.

Abstract: A device, noteworthy by its compact construction, portability and use of a constant torque spring to dispense liquid under a uniform force, in which binding due to possible rotative movement in the slide that is powered by the torque spring is obviated, so that the slide tracks properly during liquid-dispensing service of the device, This is in contrast to torque spring-operated prior art devices in which special precautions were required to neutralize the turning movement unavoidably resulting when the torque spring assumed its characteristic helical coils during its functioning.

Abstract: Using latent heat of vaporization of a selected evaporative fluid, an abnormally elevated testicular temperature is effectively diminished so as to contribute to obviating male infertility due to poor semen quality. Moreover, the evaporative method employed, and the device using such method, are particularly appropriate in that the cooling effect is achieved over a prolonged period so as to facilitate achieving the desired medical result, whereas merely diminishing the testicular temperature for a short duration would not be medically effective.
