Definitions

  • PAIENTEB SREEI 2 BF 2 llllillillll DISPOSABLE HUMIDIFIER BACKGROUND or THE INVENTION This invention relates to an improved system for humidifying oxygen that is administered to a patient.
  • the oxygen which is supplied to hospital patients must be humidified because of the inherently low humidity of the oxygen exiting conventional oxygen tanks.
  • the oxygen is passed through bubblertype humidifiers which add water to the oxygen and the humidified oxygen flows through a nasal cannula to the patient.
  • oxygen as used herein is intended to include all oxygen-containing gases, such as air, substantially pure oxygen, etc.
  • water as used herein is intended to include distilled water, tap water and other water-containing liquids, such as saline solution.
  • Contamination may also result because the first type of humidifier uses water which is obtained from the tap,
  • a second type of oxygen humidifier assembly is similar to the first type described above, but is manufactured as a disposable item for single patient use. Although this type of humidifier eliminates some risk of contamination by providing a single use product, it depends on an open water supply and thus risk of contamination exists.
  • a third type of oxygen humidifier comprises a disposable molded product which incorporates a water resersolution bottle, of the type which is disposable after use and which is normally stored by hospitals in substantial quantity.
  • the intravenous solution bottle contains its own distilled water supply and thus there is no need for the hospital staff to introduce water to the bottle from an open water supply. Further, the intravenous solution 2. midifier bottles because the same bottle is used for both purposes.
  • a further object of the present invention is to provide an oxygen humidifier which significantly avoids risk of contamination, in that it utilizes a single use bottle which is prefilled with sterile water.
  • an oxygen humidifier set which uses, as the water supply, an intravenous solution container having a stopper defining a first opening and a second opening, with an airway tube connected to the wall of the stopper defining the first opening.
  • the airway tube is coaxial with the first opening and extends to the lower portion of the container, and the first and second openings are in communication with the inside of the container.
  • a connector assembly is provided for coupling the intravenous solution container to an oxygen supply.
  • the connector assembly includes an oxygen inlet member and means for coupling the upper portion of the oxygen inlet member to the oxygen supply.
  • the lower portion of the oxygen inlet member comprises an oxygen inlet tube which is adapted for coupling to the first opening for communication therewith.
  • an outlet tube is provided for forming an outlet path for the humidified oxygen.
  • the outlet tube is adapted for insertion into the second opening.
  • a humidified oxygen outlet is provided in communication with the outlet tube, with the humidified oxygen outlet being adapted for coupling to a nasal cannula.
  • the connector assembly carries means which are engageable with the intravenous solution container, for retaining the connector assembly in engagement with the container and for supporting the container.
  • FIG. 4 is a cross-sectional elevation of the connector of FIG. 3, taken along the plane of the line 44 of FIG.
  • FIG. 6 is a perspective view of an oxygen humidifier set of the present invention, coupled to an oxygen sup- Q ply.
  • a plastic connector assembly for coupling a conventional oxygen supply to a standard intravenous solution container having water therein, in order to humidify the oxygen.
  • a standard intravenous solution container having water therein, in order to humidify the oxygen.
  • the container shown therein is a standard intravenous solution bottle,
  • bottles generally are formed of glass and are obtainable in various sizes, such as 250 m1, 500 ml, etc.
  • the bottles are maintained under sterile conditions, since they contain solutions which are intended to be introduced into the human body.
  • Bottle 10 has a bail member 12 connected thereto for suspending. the bottle during intravenous administration. However, the bail member has no utility in connection with the present invention.
  • the mouth of bottle 10 is closed by means of a rubber stopper l4 defining two openings 16 and 18 which communicate with the inside of the bottle.
  • First opening 16 is smaller in diameter than second opening 18 and has a plastic airway tube 20 mounted therein.
  • Airway tube 20 extends downwardly in the bottle 10 to a point adjacent the bottom thereof.
  • the connector assembly 26 which couples the intravenous solution bottle to a conventional supply of oxygen comprises a base 28 carrying an oxygen inlet member 30, an outlet tube 32, a humidified oxygen outlet 34 and a pair of downwardly extending fingers 35.
  • Oxygen inlet member 30 defines a central bore 36 with the that a compression fit of the inlet tube and airway tube.
  • opening 16 With opening 16 is permitted.
  • the lower end of the inlet tube 38 will be adjacent to or in abutting relationship with the upper end of airway tube 20.
  • the compression fit of the tubes in opening 16 aids in providing an effective seal.
  • Outlet tube 32 is greater in length than inlet tube 38 and has a downwardly pointing sharp forward edge 40 which aids in permitting the connector assembly 26 to 4' I be inserted into stopper 14 and further aids in providing an effective seal.
  • Outlet tube 32 has a central bore 42 which communicates with bore 44 of humidified oxygen outlet 34.
  • filter plug 43 interposed in bore 42.
  • Filter plug 43 is utilized to prevent water from being forced out, i.e., to obviate the problem of liquid droplets passing to outlet 34.
  • filter plug 43 is formed of a polyolefin material, such as polypropylene, having a pore size of 300 microns.
  • Humidified oxygen outlet 34 includes a nasal cannula adapter 46 which is connected to the assembly with a frictional fit and it tapers to permit an effective couplingof the assembly to a conventional nasal cannula 47, as shown in FIG. 6.
  • umbrella valve 48 is interposed in communication with bore 42 for safety purposes. For example, if the back pressure exceeds 2 psi, umbrella valve 48 will provide a relief vent as one side thereof is forced upwardly.
  • a plastic nipple 50 is fastened to the top of inlet member 30.
  • Nipple 50 defines a bore 52 which communicates with bore 36.
  • Nipple 50 becomes connected to a conventional oxygen supply by means of threaded coupling 54 which comprises grip wings 56 and an internally threaded bore 58 which threadedly engages a standard externally threaded outlet of a conventional oxygen supply.
  • Coupling 54 defines opening 60 which is greater in diameter than the external diameter of inlet member 30, and thus can slide alonginlet member 30, but is restrained from removal by means of nipple 50.
  • a water-containing standard intravenous solution bottle is selected and the closure is torn in the conventional manner.
  • Connector assembly 26 is then forced into the two-hole stopper, with the oxygen inlet tube 38 entering first opening 16, as described above, and the underside of base 28 resting upon the top of clamping ring 22.
  • a nasal cannula 47 is then frictionally connected to adapter 46 and the assembly is connected to a conventional oxygen supply 72 by threading coupling 54 onto the outlet of the oxygen supply.
