  • Patent number: 11439783
    Abstract: A patient interface device and cushion for the device are respectively disclosed, for preferred CPAP and BiPAP breathing masks. The cushion has a composite structure with an open rounded polygonal profile defining a mask side layer and a slip-resistant fibrous patient side layer, with an intermediate barrier layer positioned between the first and second layers. The layers are integrally bonded together into a three-dimensional conformation defining a J-shaped cross section and an inboard patient side curl opening into an air chamber juxtaposed with one or more of the patient's airways. The body exhibits flexibility between about 4 and about 10 Taber Stiffness Units. Method and apparatus for making the cushion are further described.

  • Patent number: 4907605
    Abstract: An oral nicotine dispenser comprising nicotine or a nicotine salt and a water-insoluble material capable of sorbing nicotine. The dispenser is able to slowly release the sorbed nicotine or nicotine salt in an oral environment. The water insoluble material may consist essentially of paper or a polymeric substance able to absorptively contain nicotine.The water-insoluble material may be a substance such as paper or cellulose acetate. A water-insoluble polymeric substance such as a polyolefin, most preferably polyethylene or polypropylene may be used as the nicotine-holding material.

  • Patent number: 4736755
    Abstract: A method of loading nicotine into porous polymeric items consisting essentially of a polyolefin. The method comprises contacting the items with nicotine or nicotine dissolved in a carrier. The polyolefin item, preferably polyethylene or polypropylene, may be loaded with nicotine by several variations on the basic method. The items may be emplaced in a vessel with nicotine and the vessel then closed for a period of time prior to removal of said items.A preferred method of producing porous polyethylene items loaded with nicotine comprises first emplacing porous polyethylene items in a vessel. A solution comprising between about 1% nicotine and about 10% nicotine and a solvent for nicotine demonstrating an adherence for polyethylene surfaces is prepared. A quantity of this solution sufficient to contact at least a majority of the polyethylene items is added to the vessel.

  • Patent number: 4676259
    Abstract: A nicotine-enhanced smoking article having a first tobacco portion and a second filter portion attached thereto. The filter portion containing filter fibers and a nicotine solution having 5-15%, by weight of total solution, nicotine or a nicotine salt in a solvent. The interaction of the combination products from the first portion with the nicotine solution results in the absorption by the combustion products of nicotine from the solution providing increased nicotine to the user.

  • Patent number: 4655231
    Abstract: An improved snuff containing substantially pure powdered salts of nicotine diluted with powdered organic sugars which is substantially absorbed by the nasal membranes when applied thereto. Flavoring and/or coloring agents are optionally present. The improved snuff is prepared by adding an acid to a nicotine solution, separating the nicotine salt from the solution, diluting the nicotine salt to a usable concentration, and optionally adding flavoring and/or coloring agents to enhance the fragrance and appearance of the improved snuff.
