  • Patent number: 7472705
    Abstract: A method and apparatus for delivering a medicine to a patient via the patient's respiratory system with control and efficiency. A nebulization catheter is positioned in the patient's respiratory system so that a distal end of the nebulization catheter is in the respiratory system and a proximal end is outside the body. In a first aspect, the nebulization catheter may be used in conjunction with an endotracheal tube and preferably is removable from the endotracheal tube. The nebulization catheter conveys medicine in liquid form to the distal end at which location the medicine is nebulized by a pressurized gas or other nebulizing mechanism. The nebulized medicine is conveyed to the patient's lungs by the patient's respiration which may be assisted by a ventilator. By producing the aerosol of the liquid medicine at a location inside the patient's respiratory system, the nebulizing catheter provides for increased efficiency and control of the dosage of medicine being delivered.

  • Patent number: 6079413
    Abstract: An improved system for delivery of an aerosolized medicine to a patient's respiratory system. The system uses a pressurized canister that contains a mixture of a medicine and a propellant which may be in a liquid state. The canister has an outlet from which the mixture can exit. The system includes an extension catheter that connects at a proximal end to the outlet of the canister. The extension catheter has a length such that a distal end can be positioned either in an endotracheal tube or deep in the respiratory tract of the patient while the proximal end of the extension catheter is connected to the canister which is located outside the patient's body. The extension catheter includes at least one lumen extending therethrough for conveying the medicine and liquid propellant mixture from the canister to a distal exit orifice where an aerosol can be generated as the propellant evaporates. The aerosolized medicine is carried by the patient's inhalation and delivered to the lungs.

  • Patent number: 5988160
    Abstract: A mask is provided for the inhalation of medication, such as asthmatic medication. The mask is molded of a resilient plastic or rubber material and has a central through opening and includes an open front portion adapted to receive an aerosolization chamber which receives medication from a metered dose inhaler. A sidewall expands outwardly from the open front portion and is adapted to fit sealingly on a face covering the mouth and nose. The sidewall is provided with an extension to accommodate the nose. A one-way exhalation valve is provided in the mask, preferably at the far end of the nose accommodating extension for conveying exhaled air to the outside, and preventing entrance of outside air therethrough into said mask.

  • Patent number: 5627324
    Abstract: A peak flow meter is provided comprising an elongated body having a longitudinal direction and a predetermined cross sectional shape and a growing area. The body has an open entering end and an open exit end. The body is circumferentially continuous substantially from end to end. A piston and an indicator are mounted in said body for movement longitudinally thereof upon exhalation into the open entering end. The indicator is pushed along said body for movement by the piston longitudinally of said body. The indicator is of low mass so as not to overshoot, and is returned to rest by shaking a weight against it. A logarithmic scale is provided along said body against which the position of said indicator can be read.
