  • Patent number: 10342902
    Abstract: An occlusion clearing device and system for removing material from an artificial tube in situ includes a clearing stem having aspiration and irrigation conduits, where the irrigation conduit is disposed interior to, and terminates within the aspiration conduit. Material enters the clearing stem through aspiration, and irrigation is provided within the aspiration conduit to assist in aspiration through the clearing stem. A handset includes aspiration and irrigation tubing connecting to sources therefor, and further includes valves to control the flow through the tubing and conduits. These valves may be operated simultaneously with an actuator located on the handset, which may be done with one hand. A coupler at the operative end allows the clearing stem to gain access to the artificial tube for clearing while maintaining a closed system with a ventilator. Reciprocating motion may be generated and provided to the clearing stem to aid in occlusion removal.

  • Publication number: 20190192385
    Abstract: An occlusion clearing device for a patient has a housing with a motor(s) that generates repetitive motion, which is reciprocating, rotational or both. A clearing stem including a sheath that has a lumen, wherein aspiration is conducted through the sheath lumen. A wire is located in the sheath lumen and receives repetitive motion from the controller. The sheath terminates in a sheath end having at least one sheath opening. The wire terminates in a wire tip, which may be flat, helical, or tubular. The wire tip is positioned within the sheath end, in proximity to the sheath opening(s), and movement of the wire tip and/or sheath end relative to each other creates shearing forces that break up an adjacent occlusion.

  • Patent number: 6552163
    Abstract: A poly(ethylene oxide) polymer having low and high molecular weight fractions is fractionated by dissolving the polymer in a solvent for the low molecular weight fraction. A good separation of the low and high molecular weight fractions can be obtained. When the poly(ethylene oxide) polymer contains a metal cyanide catalyst, this process also provides a good separation of the catalyst from the low molecular weight fraction. In this instance, the catalyst remains active and the high molecular weight fraction containing the catalyst can be recycled into subsequent polymerization processes.

  • Patent number: 5873981
    Abstract: A is a process for removing water from an alkanesulfonic acid such as methanesulfonic acid or ethanesulfonic acid by mixing an azeotropic excess of a phenolic compound with water and the alkanesulfonic acid, then boiling off substantially all of the water, and leaving as a remnant substantially all the alkanesulfonic acid and some of the phenol. This process is particularly useful for recycling an alkanesulfonic acid for a reaction which requires the phenolic compound as one of the reagents. One such reaction is the alkanesulfonic acid catalyzed condensation reaction of a phenolic compound with an .alpha.haloketone to form a chlorinated intermediate of a dihydroxy-.alpha.-alkylstilbene such as 4,4'-dihydroxy-.alpha.-alkylstilbene (DHAMS).

  • Patent number: 5723692

  • Patent number: 5578737
    Abstract: Compounds having acidic protons and a molecular structure which can delocalize the electron density of the conjugate base (target compounds) are chlorinated by contacting such compounds with a perchloroalkane and aqueous base in the presence of a phase transfer catalyst which is an tetraalkylammonium hydroxide. Chlorinated products, preferably gem-dichloro compounds, are produced. The gem-dichloro compounds are useful for alkylation of aromatic compounds. For instance fluorene is chlorinated to form 9,9-dichlorofluorene which is reacted with such compounds as phenol or aniline to form such compounds as 9,9-bis(hydroxyphenyl)fluorene, 9,9-bis(aminophenyl)fluorene, or 9-aminophenyl-9-chlorofluorene.
