Abstract: A urine collection system for females comprised of a soft, flexible, sealing member forming a seal around the external urethral ostium, by conformation to and adhesion to the tissue surface. A conduit, or drain, passes through the sealing member leading to collection and storage means for the urine. A positioning or orientation member is provided to achieve alignment of the conduit lumen through the sealing member with the urethral orifice.

Abstract: A mechanical drive system for driving a syringe, or other fluid infusion system, over extended period of times, which drive system also provides manual advance and quick release features. Manual advance and quick release is selectively provided by mechanically decoupling the gear train from the syringe drive mechanism.

Abstract: A high reliability drive arrangement produces a rate-controlled output displacement and is particularly suited for driving a medical infusion apparatus. Energy for producing the output displacement is derived from a wound spring which, in a preferred embodiment, is coupled to an output shaft by a redundant gearing system. First and second drive gears, and their associated pinions on the output shaft, are rotationally displaced with respect to one another to prevent alignment of potentially defective gear teeth and to align the teeth on one gear with the inter-tooth spacings on the other. The output shaft additionally engages a rate-control arrangement which governs the rate of rotation, and consequently, the rate of the displacement. The possibility of uncontrolled rotation is reduced by providing a safety arrangement having a safety gear plate which has fewer teeth than its associated drive gear.

Abstract: This invention discloses compositions useful as dentifrices or oral medicaments and capable of inhibiting microbial mouth infections. The compositions contain an effectiveamount of silver and/or zinc sulfadiazine and a suitable carrier. By inhibiting microbial mouth infections, these compositions reduce or eliminate dental caries, plaque formation, gingival destruction, bone and tooth loss. The compositions of this invention may be in the form of liquids such as mouthwashes, pastes such as toothpastes or solids such as chewing gums or coated dental tapes or flosses.
