Definitions

  • This invention relates to a nebulizer apparatus and more particularly, but not exclusively, to a nebulizer apparatus for medical use.
  • the most simplistic method of preparing a medicinal inhalant is by dissolving a medicine in boiling water. The resulting vapour is inhaled by the patient.
  • water can be vaporised and the steam filtered through a separate chamber containing medicinal crystals or fluid.
  • Conventional humidifiers can also be used to inhale medicine by allowing the steam from the humidifier to diffuse with the drug before it is inhaled.
  • An object of the present invention is to provide a useful alternative to nebulizers already available on the market.
  • a nebulizer apparatus comprising a container for a fluid; a heater for heating the fluid; a first end of an outlet pipe connected to the container, for conveying evaporated fluid from the container; and an inlet having a non-return valve for allowing a second fluid to be forced into the container in one direction only.
  • the container to include a closure member.
  • the closure member is in the form of a lid.
  • the lid includes a seal for sealing fluids inside the container.
  • the heater to be an electric heater and to include an electric resistive element.
  • a second end of the outlet pipe to terminate in a mouthpiece; alternatively, to terminate in a mask.
  • the nebulizer apparatus includes a pump for pumping a gas into the container through the inlet and then out through the outlet pipe.
  • a still further feature of the invention provides for the heater to be adjustable.
  • a yet further feature of the invention provides for the fluid in the container to be a medicinal fluid mixture; more particularly, to be a water, salt and medicinal composition mixture.
  • a stand may also be provided for supporting the outlet pipe in a desired position.
  • Figure 1 shows an exploded view of a nebulizer apparatus according to the invention
  • Figure 2 shows a cross-sectional front view of the nebulizer apparatus of Figure 1 ;
  • Figure 3 shows a cross-sectional view of a second embodiment of a nebulizer apparatus according the invention.
  • a nebulizer apparatus is generally indicated by reference numeral 10.
  • the nebulizer 10 consists of a container 12, for receiving a fluid and more particularly a medicinal fluid 13; an electric heater in the form of a metal base plate 14 having a resistive element 18, for transferring heat to the medicinal fluid 13; an outlet pipe 16 connected to the container 12, for conveying vaporised medicinal fluid 13 from the container 12.
  • the heater is electrically powered and an electrical cord 22 and is provided.
  • the heater can be set to operate at different levels using a dial 19.
  • An inlet 24 having a non-return valve is situated in a wall of the container 12.
  • the inlet 24 enables the passage of compressed oxygen (not shown) from a compressed oxygen source (also not shown) into the container 12 from a second pipe, the second pipe being releasably connectable to the inlet 24.
  • the nebulizer 10 may include its own built-in air pump 25 for pumping ambient air or an oxygen through the container 12 and outlet pipe 16.
  • a closure member in the form of a lid 26 has a first thread 30, which is engagable with a corresponding second thread 32 at an open end of the container 12. The lid seals fluids inside the container.
  • medicinal fluid 13 is placed inside the container 12.
  • the lid 26 is screwed onto the container 12 thereby sealing the medicinal fluid 13 inside the container 12.
  • the medicinal fluid 13 is a mixture of water and a medicine and it is envisaged that, in most cases, it will be a mixture of water, salt and a medicinal composition.
  • a heat setting is selected using the dial 19.
  • a heating element 18 heats the base plate 14 according to the selected heat setting.
  • the base plate 14 transfers heat from the heating element 18 to the container 12 thereby heating the medicinal fluid 13.
  • the medicinal fluid 13 is evaporated and escapes from the container 12 through the outlet pipe 16.
  • the evaporated medicinal fluid can be conveyed by the outlet pipe 16 to a mask 36, a sprayer or a mouthpiece.
  • compressed oxygen can be filtered through the medicinal fluid 13.
  • a second pipe is connected to the inlet 24, which enables oxygen from an oxygen source or ambient air to flow into the container 12 and through the medicinal fluid 13.
  • the pump of the nebulizer of figure 3 can be used to pump ambient air or an oxygen rich mixture.
  • the nebulizer will provide a useful and relatively inexpensive alternative to existing machines.
  • the outlet pipe is convenient in that it is flexible and the evaporated medicinal fluid can be aimed and concentrated where required.
  • the container closure means need not be in the form of a screw-on lid but may be a hinged lid that is clamped onto the container thereby sealing it; any gas may be filtered through the medicinal fluid; and the heat transfer means may be comprised of any heat conducting material and need not be a plate.
  • the container may be double-walled and may contain insulation material between the walls to enhance its efficiency.
  • a stand may be provided to support the outlet pipe in a desired position.

Abstract

L'invention concerne un dispositif de nébulisation, notamment un dispositif de nébulisation à usage médical. Le dispositif de nébulisation selon l'invention comprend un réservoir destiné à recevoir un fluide. Un dispositif de chauffage est inclus dans le réservoir et sert à chauffer le fluide de sorte que ce dernier s'échappe par un conduit de sortie relié à une sortie du réservoir. Le réservoir comprend également une entrée munie d'un clapet de non-retour et permettant de filtrer un deuxième fluide, tel qu'un gaz riche en oxygène, à travers le fluide dans le réservoir. Le dispositif comprend également un couvercle obturant une extrémité ouverte du réservoir.
