  • Patent number: 4445626
    Abstract: A cylindrical container for viscous material has a first open base end of a first diameter and a spaced opposite closed base end with an opening therethrough of a second diameter smaller than the first diameter. A cylindrical plunger of a third diameter slightly smaller than the first diameter is coaxially slidably mounted in the container in a snug manner. The plunger has a closed plunger head perpendicular to its axis. A positioning device selectively positions the plunger and the container relative to each other at a plurality of different axial positions. The plunger, at each of the axial positions, forces a predetermined measured amount of the viscous material out of the opening of the container.

  • Patent number: 4392492
    Abstract: Apparatus for storing and dispensing a medicated douche solution includes a sealed unitary packette as one of its components and which has a predetermined volume of liquid douche concentrate stored within a sealed interior volume defined thereby. The packette is formed of thin flexible plastic material and includes a container portion in which the douche concentrate is stored and a dispenser portion integral with the container portion and which is constituted by an elongated, small diameter tubular stem which has a constant transverse cross-section throughout its length and a separable terminal tip portion. The packette is openable through separation of the terminal tip portion from the dispenser portion whereupon the dispenser portion is inserted through an opening of a bottle containing a diluent so as to extend to a significant extent into the interior thereof. The concentrate is dispensed into the diluent by squeezing the container portion of the packette.

  • Patent number: 4364929
    Abstract: Germicidal properties are provided for colloidal lubricating gels without destruction of the physical properties of the colloidal gel by the incorporation therein of an iodophor within strict limits as to the quantities and relative quantities of the iodophor-former, the iodine and the gel-forming colloid. These germicidal colloidal lubricating gels remain stable and retain their germicidal effectiveness. As a result, these compositions can be used for the lubrication of catheters and other instruments to facilitate their insertion into a body cavity and because these compositions do not cause pain or irritation their use reduces the risk of infection and tissue-trauma.

  • Patent number: 4167186
    Abstract: A syringe, particularly a vaginal douche, has a cannula consisting of an elongated hollow tubular body having one open end and an opposed transverse end wall formed with an opening through which a central axis of the cannula body extends. The cannula body has substantially midway between its ends a transverse minimum cross section while tapering only slightly from the transverse end wall toward the minimum cross section. Between its open end and its minimum cross section the cannula body tapers to a substantially greater degree and has the configuration of part of a hollow cone. At its exterior between its minimum cross section and transverse end wall the cannula body is formed with grooves uniformly distributed about the central axis of the cannula body and separated from each other by ribs. Adjacent but inwardly of these ribs the cannula body is formed with additional openings passing therethrough so that a liquid can discharge through the cannula openings.
