- ABSTRACT A disposable sealed container as it is formed is aseptically filled with water for inhalation therapy.
- a first duct fashioned integrally with the container has an integral breachable seal to provide an opening for passing oxygen under pressure through the water when the container comprises a humidifier reservoir for operating in a first mode and for removing water when the container comprises a nebulizer reservoir for operating in a second mode.
- a second duct fashioned integrally with the container has an integral breachable seal to provide an opening through which wetted oxygen is forced outwardly when the container operates in its first mode and through which atmospheric air is drawn when the container operates in its second mode.
- a first fitting selectively mounted on said first duct has a seal breaching element and an inlet end for passing oxygen from a pressure source into the container and enables its operation in said first mode.
- a second fitting selectively mounted on said first duct has a seal breaching element and a Venturi-like section for drawing and atomizing water from said container and enables its operation in said second mode.
- the present disclosure relates to inhalation therapy. Particularly it relates to humidifiers and nebulizers of thetype used in inhalation therapy.
- Inhalation therapy is an art of treating with oxygen having a high moisture content.
- the moisture may be provided by humidification of oxygen or atomization of water.
- Apparatus known as humidifiers are adapted for effecting the former by discharging into the atmosphere oxygen which has been broken into bubbles and has been forced under pressure through a volume of water.
- Apparatus known as nebulizers are adapted for effecting the latter by discharging into the atmosphere water which has been broken into a mist of fine drops.
- a conventional humidifier comprises a water container of glass fabrication with an upper closure.
- a metal oxygen supply tube extends through the closure. It carries a radial perforated plate at its lower end for breaking up oxygen, introduced under pressure through the tube, into bubbles. As the bubbles rise through the water, they become moisture coated for discharge into the atmosphere.
- a conventional nebulizer of the type with which this disclosure is concerned comprises a water container of glass fabrication with an upper closure.
- a Venturi tube which may be of rigid plastic fabrication is associated with the closure. It utilizes oxygen under pressure to atomize water in the container and force the atomized water through a tube opening into the atmosphere.
- Disposable humidifiers and nebulizers are provided by manufacturers in completed condition with sterile water. Therefore, an institution, such as a hospital, is required to have an inventory of humidifiers and nebulizers, each with its water container, if it is to satisfy all requirements. Because of the high cost attendant using con ventional inhalation therapy apparatus, many institutions use reusable humidifiers and nebulizers. But this practice creates a burden on trained personnel, already in short supply. Moreover, whether it produces the desired economy is highly disputable.
- a container for inhalation therapy apparatus. It comprises a body having a chamber definsaid chamber and a lower end portion fluidly connected with said chamber below the normal liquid level.
- a second duct is integrally connected to said body above the normal liquid level in the chamber and has a passage fluidly connected to said chamber.
- a breachable seal defines a penetrable sterile barrier integrally fashioned with each of said ducts for isolating a BRIEF DESCRIPTION OF THE DRAWINGS
- FIG. 1 is a view of a container embodying the invention and being partially elevational and partially sectional;
- FIG. 2 is a view according to the section line 2-2 on FIG. 1;
- FIG. 3 is a view of an upper portion of said container in section and adapted as a humidifier
- FIG. 4 is a view similar to FIG. 3, however, showing said container adapted as a nebulizer.
- a container generally designated 10 is shown vertically oriented. It is comprised of a body 12 having therein a chamber 14 which defines a reservoir for water 16. Body 12 has a bottom 18, and at its upper end a restricted neck 20 forms a transition component atop of which there is a small head 22 from which a nose-like duct 24 extends. An external thread 26 is fashioned on the wall of duct 24, and its passage 28 has an axis which is disposed normally to the vertical axis of body 12.
- Another duct 30 has a passage 32 which is vertically disposed on an extends along the outside of body 12.
- a vertical section 34 of the wall defining said body is integral with or common to the wall defining duct 30 and said section separates the upper portion of passage 32 from chamber 14.
- the bottom of section 34 is spaced upwardly from bottom 18 and thereby generates a channel 36 through fluid-passage which the lower end portion 38 of passage 32 is fluidly connected to chamber 14. Accordingly, water 16 will have a common level in chamber 14 as well as duct 30.
- the last duct has an upper end portion 40 which extends outwardly from body 12 and is spaced apart from head 22 and duct 24 to which said upper end portion is normally disposed.
- A. thread 42 fashioned externally of said upper end portion comprises means enabling operation of container 10 selectively as a reservoir for a humidifier and a reservoir for a nebulizer, as will become more fully apparent from ensuing description.
- a pair of tearable or rupturable membranes 44 and 46 disposedat the outer ends of ducts 24 and 30 comprise breachable sealing means which completely close ducts 24 and 30 and wholly isolate water 16 from the atmosphere.
- Membrane 44 when breached enables passage of: (a) humidified oxygen from chamber 14 to the atmosphere in the direction of arrow 48 (FIG. 3) when container 10 functions as a humidifier reservoir and (b) atmospheric air into chamber 14 in the direction of arrow 50 (FIG. 4) when the container functions as a nebulizer.
- Membrane 46 when breached enables passage of: (a) oxygen in the direction of arrows 52 and 54 when the container functions as a humidifier reservoir and (b) oxygen and water, respectively, in the directions of arrows 56 and 58, and a combination thereof in the direction of arrow 60, when the container functions as a nebulizer reservoir.
- Preferred container is fashioned of a semirigid plastic such as polypropylene. However, the particular material is not limiting on the invention.
- the container is blow molded, ducts 24 and 30 and wall section 34 as well as membranes 44 and 46 being integrally fashioned with body 12 as part of the molding process.
- the container will be sterile filled with water to a desired level during the molding process, using known art for plastic container formation and simultaneous filling and modified, of course, to accommodate the present container design. Further description of the molding and filling process is omitted as its details do not form a part of the present invention.
- An oxygen coupling means generally designated 62 (FIG. 3) enables use of container 10 as a reservoir for a humidifier. It comprises a fitting or cup-shaped female 64 concentric about a vertical axis and with an internal thread 66 for mating with thread 42.
- An axially' elongated oxygen tube 68 has a preferably fixed lower end portion extending through the top wall 70 of the female. In the illustrated embodiment said lower end portion is fashioned as a piercing, tearing or breaching element 72 disposed within said female. Accordingly, as said female is threaded on the thread 42 of duct 30,
- membrane 46 will be torn or breached and its passage 32 will become fluidly connected with a vertical passage 74 which extends through said oxygen tube.
- Oxygen coupling means 62 comprising a second internally threaded female fitting 76 for fluidally connecting duct 30 to a supply source (not shown) for providing oxygen under'pressure.
- Fitting 76 has a stepped internal axial bore 76 whereby there is generated a medial internal annular shoulder 80 and a lower annular lip 82.
- the passaged upper end portion 88 of oxygen tube 68 extends through the center of pop out plug 84 in sealed engagement therewith.
- the association is frictional such that said pop out plug and the oxygen tube may be relatively rotated under manual force.
- the top of the oxygen tube is sealingly held in frictional engagement in the stepped central hole 90 of a compressible sealing member 92, which is mounted on shoulder 80 in vertically spaced association with the pop out plug.
- the parts are proportioned such that a male member (not shown) on which fitting 76 is adapted to be mounted will press sealing member 92 against shoulder 80 upon assembly.
- the parts also are proportioned such that oxygen 1 with a meter pressure of 50 lbs. p.s.i. when introduced into passage 32 through passage 74. will force its wayto the bottom of chamber 14. There it will form a large bubble and pass upwardly through water 16 in said chamber for removal therefrom to the atmosphere in humidified condition through passage 28, provided that membrane 44 has been breached.
- V v oxygen 1 with a meter pressure of 50 lbs. p.s.i.
- a horizontally passaged catheter adapter or fitting 94 having an internal thread 96 for mating thread 26 is threadedly engaged on duct 24.
- An inwardly projecting breaching member 98 which may be fashioned integrally with adapter 94, is arranged and proportioned such that, as said adapter is threaded on said last duct, membrane 44 will be torn, ruptured or breached for en abling escape of humidified air from chamber 14 in the direction of arrow 48, as aforesaid.
- a Venturi-like structure generally designated 100 (FIG. 4) enables use of container 10 as a reservoir for a nebulizer. It comprises a T-shaped body having a section 102, shown vertically oriented, and a fluid outlet section 104, shown horizontally oriented. The latter has a wide horizontal passage 106 opening to atmosphere and may be externally threaded as at 108 to enable connection to a member such as a tube or fitting (not shown) for further directing fluid output.
- Body section 102 is generally vertically passaged having an upper passage 1 l0 and a lower passage 112 which are disposed in parallel though superposed association.
- a short horizontal passage 114 of relativelysmall diameter in axial alignment with and fluidly connected to the inner end of opening 106 fluidly connects passages and 1 12.
- Passage 110 is defined by the tubular upper end portion 116 of body section 102.
- a fitting 118 which may be of identical construction to fitting 76 is mounted on the outermost end part of said upper end portion for fluidly connecting structure 100 to an oxygen supply source (not shown). Accordingly, further description of fitting 118 is omitted.
- Passage 112 is defined by the lower end portion 120 of body section 102.
- the lowermost part of said body section is fashioned as a female or receptacle 122 with which passage 112 fluidly communicates.
- a thread 124 fashioned internally of said receptacle is proportioned for mating with thread 42 whereby assembly 100 may be mounted on duct 30.
- a breaching tool 126 which projects into receptacle 122 defines the lowermost part of passage 112. The tool is proportioned such that it will breach, tear or rupture membrane 46 when assembly 100is threadedly mounted atop duct 30. Thereby fluid communication can be established between passage 32 and opening 106 through passages 112 and 114.
- Body section 102 comprises a Venturi tube in which the lower end portion of passage 1 10 is fashioned as at 128 such that oxygen introduced therein under pressure in the direction of arrow 56 through fitting 118 will be directed at right angles through passage section 114 and expelled through outlet section 104 in the direction of arrow 60.
- oxygen movement will cause water 16 to be drawn up passage 32 in the direction of arrow 58, through passage 112, into passage 114 down-stream of its juncture with section 1 10 and broken up into a spray of fine droplets which will be expelled with the oxygen, provided membrane 44 is breached.
- a fitting 130 which may be of identical construction to fitting or adapter 94, is mounted on duct 24. Accordingly, further description of fitting 130 is omitted. However, in this case, passage of fluid is in the direction of arrow from container 10.
- a liquid container for inhalation therapy apparatus comprising:
- a body having a walled chamber with a body collectively constituting a reservoir for a liquid; said reservoir having a predetermined amount of liquid therein;
- a first duct having a passage with an upper end portion disposed above the normal level of said liquid and a lower end portion fluidly connected with said chamber below the normal level of said liquid and a major longitudinal portion of said duct being integral externally with respect to a wall of said body;
