  • Patent number: 5725842
    Abstract: Methods are disclosed for removing retained mucus secretions from the lungs of a human subject. The method includes (1) generating an aerosol suspension of respirable solid, dry particulate amiloride, and (2) delivering by inhalation the aerosol suspension to the respiratory system of the subject. The solid particulate amiloride is comprised of particles of about 1 to 5 microns and is free of liquid amiloride particles. The aerosol suspension of respirable solid particulate amiloride is administered in an amount sufficient to achieve concentrations of amiloride on the airway surfaces of from about 10.sup.-7 to 10.sup.-3 Moles/liter. As a result of the treatment, the secretions are hydrated and more easily transported from the lung via mucociliary action. Methods are also disclosed for the treatment of cystic fibrosis in humans.

  • Patent number: 5678570
    Abstract: A method of treating a subject under cardiac arrest comprises the steps of: blocking the descending aorta of the subject; then withdrawing blood from the subject; oxygenating the blood withdrawn from the subject; and perfusing the aortic arch of the subject with oxygenated blood in an amount effective to deliver oxygen to the heart of the subject. This method enables the subject to continue to receive oxygenating material (i.e., blood in this instance) without the danger of volume overload that would be present if another oxygenated solution were continuously infused.

  • Patent number: 5666492
    Abstract: A computer based pharmaceutical care cognitive services management system and method allows the transformation of a pharmacist from a vendor to a health care provider. The pharmaceutical care cognitive services management system and method captures all of the value added by a pharmacist to a patient encounter by permitting multiple RARs (Reasons, Actions, Results) to be associated with a single SOAP (Subjective, Objective, Assessment, Plan). This system enables the pharmacist to financially recover for each analytical or counseling session and/or service provided to the user associated with a single transaction. The pharmaceutical care cognitive services management system and method also enables the efficient processing of interruptions to cognitive and counseling sessions.

  • Patent number: 5107785
    Abstract: A concrete floatation module adapted for use as a floating dock, breakwater, and the like. The module includes thickened portions of concrete extending lengthwise in a concrete shell preferably in the corner portions of the shell. The shell surrounds a buoyant foam core which may be used as a molding core for the floatation module. The thickened lengthwise extending portions of concrete include integrally molded tubular liners for creating passageways through the module for the passage therethrough of an interconnecting means, such as a steel cable. The tensioned steel cables maintain the modules in compression in an end-to-end relation thereby forming a single monolithic structure. Widthwise extending liners may also be provided to facilitate the interconnecting of laterally extending branches of modules. The floatation modules may be readily formed on-site by integrally molding the buoyant foam core and tubular liners in the concrete shell.

  • Patent number: 5025754
    Abstract: A drinking water distribution system for poultry is disclosed providing poultry such as turkeys and chickens with fresh clean drinking water. The system utilizes gravity feed to distribute water from a reservoir through a conduit to a series of water cups connected to the conduit in open communication with the conduit and extending upwardly therefrom. The conduit and reservoir are suspendingly supported above the floor of the poultry house by cables depending downwardly from overhead portions of the poultry house and connected to a winch so as to be easily raised to a suitable height to accommodate growth of the poultry. The system further monitors the water temperature and if the temperature of the water gets too warm, the system replaces it with water of a lower temperature. The invention further includes an arrangement for periodically purging and cleansing the system by replacing the drinking water with liquid disinfectant for a predetermined dwell period.
