Definitions

  • Inhalation therapy has been used very extensively in recent years for treatment of emphysema and other lung and respiratory diseases as well as post operative treatment and cardiac patient care.
  • One form of inhalation therapy involves mixing a breathable gas such as air or oxygen with a liquid.
  • This humidified gas is supplied to a mask, nasal cannula, or tent, where it is breathed by the patient and absorbed by his lungs.
  • a conventional medical humidifier system includes a dry gas source such as a portable oxygen tank or central oxygen supply system of a hospital, coupled with a container of the humidifying liquid. Humidification is accomplished by atomizing the liquid into the gas or bubbling the gas through the liquid.
  • my invention 1 have provided a special adapter with a dry gas inlet passage and a humidified gas outlet passage which adapter snap locks into permanent connection with a bottle cap to provide an inlet-outlet port system for the bottle.
  • the special adapter is supplied to the hospital encased in a sterile chamber of an outer cap of the bottle. Immediately before use a nurse tears off the outer cap, removes a barrier closing off the bottle outlet and then pushes the special adapter into the bottle closure where it locks into permanent connection with the bottle.
  • the adapter is then connected to an oxygen or other dry gas source where the adapter suspendingly supports the bottle while its liquid contents are consumed in the humidifying process.
  • FIG. 1 is a front elevational view partially in section showing the bottle adapter and outer cap combination as supplied to hospitals ready to use;
  • FIG. 2 is an enlarged fragmentary front elevational view of the adapter after it has been connected to the bottle and to a gas supply source;
  • FIG. 3 is an exploded enlarged sectional view showing the various parts of the special adapter
  • FIG 4 is a front elevational view showing the adapter supporting the medical liquid bottle from a flow meter connected to an oxygen tank;
  • FIG. 5 is a front elevational view showing the medical liquid bottle after the outer cap has been removed but before the adapter has been inserted into the closure system.
  • the unit includes a bottle 1 containing a liquid 2 to be consumed in the humidifying process.
  • a neck portion 3 that defines an outlet of the bottle.
  • Permanently bonded to the neck surrounding the outlet is an inner cap 4.
  • This inner cap 4 has a central passage 5 defined by a sleeve 6 which is integrally formed with a top wall 7 of the inner cap.
  • a tear. off barrier film 8 of thermoplastic and metal foil seals off passage 5 and is bonded to sleeve 6. The bond between barrier film 8 and sleeve 6 is sufficiently strong to withstand steam or water immersion sterilization at 240 260 F. and maintain a bacteria-tight seal.
  • the film 8 can be peeled off to open close the bottle so that no liquid can escape before, during, and after sterilization until a nurse or physician peels off the barrier film 8.
  • an outer cap 10 Fitting over the inner cap 4 and the neck portion of the bottle is an outer cap 10 with a large interior hollow chamber 11.
  • This outer cap 10 is permanently bonded to the bottle and has a rip apart tear strap 17 for gaining access to the inner cap. Prior to peeling off tear strip 17 the outer cap forms a protective package for the inner closure 4.
  • Fittinginside hollow chamber 11 is a special adapter 12 which is encased in a flexible protector bag 13.
  • a multistage sieve column 15 submerged in the liquid 2 of bottle 1. Dry gas, such as oxygen, is'supplied through a dry gas supply tube 16 and is humidified in the column.
  • This mixing column is of modular snap together construction and is explained in more detail in my copending patent application entitled Mixing Column for Medical Humidifier and Method of l-lumidifying Inhalable Gases," filed June 19, i972, Ser. No. 264,314.
  • the barrier 8 is peeled off of the inner cap 4 to open up the entrance passage 5 of the inner cap.
  • the adapters lower end is then forced down into passage 5.
  • the bag may be kept on an upper portion of the special adapter to protect it from contamination by the nurses hands as it is shoved into the inner cap passage 5.
  • a screw cap 26 at an upper end of the adapter is then threadingly secured to an oxygen or other dry gas source 21.
  • This dry gas source is shown schematically as a nipple outlet in FIG. 2.
  • the term dry gas is used to distinguish the input gas, such as oxygen, from the humidified gas delivered to a patient.
  • a supply tube 22 is then connected to a tubular side arm 23 of the adapter. Withthis connection as shown in FIG. 2.
  • gas from dry gas source 21 is fed through the adapter 12 and into the bottle 1. Here it is humidified by mixing with the bottles liquid content and is thereafter fed out through tube 22 to a patient.
  • This tube could lead to nasal cannula, oxygen mask, an oxygen tent, etc.
  • the purpose here is to supply humidifled gases directly into the lungs of the patient when it can be absorbed by his body.
  • FIG. 4 The complete inhalation therapy humidified system as connected together is best shown in FIG. 4.
  • an oxygen tank has a dispensing valve 31 which is connected to a regulator 32 and a pressure gauge 33.
  • the regulator is in turn connected to a flow meter 34.
  • the bottom of the flow meter 34 has a nipple 35 which corresponds to the schematic gas supply line 21 in FIG. 2.
  • the special adapter 12 is connected to the nipple 35 and supports the bottle 1 therebelow.
  • the supply tube 22 here is shown connected to a breathing mask 36.
  • the adapter 12 has a body member with a first passage 41 that extends from an upper end 42 to a lower end 43. This passage carries the dry gas from the dry gas source into the liquid supply bottle.
  • Body member 40 also has a second passage 44 that extends upwardly from a bottom end 43 to a mid-portion of the body and there communicates with a passage 45 of a tubular side arm 23.
  • the second passage 44 is annularly disposed between an outer tubular wall 47 and an inner tubular wall 48 which are concentrically located on a common longitudinal vertical axis as shown in FIG. 3.
  • the passage structure of the body member 40 includes an inlet passage 41 for dry gas and an outlet passage 44 for humidified gas.
  • the body member 40 also includes a flexible pressure relief valve system 49 which is described in more detail in my co-pending application entitled Audible Pressure Relief Valve for Medical Humidifier, filed June.
  • a top connecting structure connecting the adapter and attached bottle to a dry gas supply source.
  • This structure includes an upper portion of body member 40 that has an annular flange 50 with a sloping lead-in surface 51 and a retention shoulder 52.
  • a separate element of the connecting structure of adapter 12 is a threaded nut or screw cap 26 with an internal lock flange 54 adjacent one end. This lock flange is separated from an internal wall surface of the lock nut by a space 57 and has a sloping surface 55 that joins with retention surface 56. To assembly the lock nut to the body member 40 the nut is pushed down upon flange 50.
  • the retention surface 56 abuts and slidingly engages shoulder 52 to permanently lock the nut to the body member 40.
  • the lock nut 26, thus, is free to rotate on body member 40.
  • Fitting over an upper end or, mouth of lock nut 26 is a protector cover 60 that includes a series of internal locking ribs 61. These ribs snap over an outer flange 62 surrounding a lip of the locking nut to connect the cover and nut together until removed by a nurse or physician immediately prior to use.
  • a bottom connecting structure of external flange with tapered lead-in surface 71 and an abutting shoulder 72 is a bottom connecting structure of external flange with tapered lead-in surface 71 and an abutting shoulder 72.
  • This bottom connecting structure mates telescopically with the sleeve 6 of inner cap 4 in a snap fit that temporarily expands sleeve 6.
  • the internal mating structure of sleeve 6 of the cap is shown in the lower portion of FIG. 3.
  • a wedge surface 73 of the inner cap extends between to a tapered lead-in funnel portion adjacent a lip 77 and a retention shoulder 74.
  • This shoulder 74 is perpendicular to a longitudinal axis of sleeve 6 so the adapter can be rotated in sleeve 6 without unscrewing therefrom.
  • the cap 4 has a skirt 75 that is permanently bonded to the bottle neck 76.
  • the only entrance to the bottle is through passage 5 of sleeve 6.
  • the adapter body 40 is shoved into 7 passage 5. This does two things. First, it intermeshes and permanently locks the abutting shoulder surfaces 72 and 74 together, while allowing the bottle to be rotated through 360 relative to the adapter to orient the bottles volume indicator for clear viewing. Since the outer cap 4 is permanently connected to the bottle, the adapter 12 is now permanently locked to the bottle and cannot be used for administering a different bottle of liquid.
  • the second thing to occur when the adapter is shoved into passage 5 is a guided telescopic fitment between the dry gas tube 48 of the adapter and a dry gas tube 78 within the bottle.
  • Dry gas tube 78 has an upper lead-in surface 79 that engages with a thinned wall portion 80 of the adapters dry gas tube 48.
  • the tubes 48 and 78 can be axiallyaligned, and telescopically joined at their ends to create a hollow supply line through the adapter 40 and into a lower portion of the bottle where humidification of the gas begins.
  • the adapter is connected to an oxygen tank or an oxygen wall line for suspending the bottle as shown in FIG. 4.
  • the liquid contents of the bottle are then consumed to a recommended level of the bottle.
  • the screw nut or cap 26 is loosened from flow meter 34 and the bottle discarded. If a patient needs therapy from more than one bottle, a replacement bottle of liquid is connected as shown in FIG. 4 in the same manner as described above.
  • An important feature of this structure of the applicants invention is that the nurse is required to use a new sterile adapter with each bottle that is opened. This keeps down risk of cross-contamination between patients, and mixing of different medicaments from bottles that proceed through a common adapter. After a single treatment on a single patient the entire bottle and adapter are discarded.
  • a disposable dry medical gas humidifying assembly including means for connection to said means for dispensing the dry medical gas from the source; and means for administering humidified medical gas to a patient
  • said gas humidifying assembly comprising a disposable container for a medical liquid, said container including connection-andretention means; and an adapter for connecting the dry medical gas source with the medical liquid container comprising a body member having a dry gas passage extending from an inlet adjacent a top portion of the body member to an outlet adjacent a lower portion of the body member, and a humidified gas passage extending from an inlet adjacent a lower portion of the body member upwardly to an exit portion on the body member; first connecting means on the body member at the dry gas passage inlet for connecting the adapter to the medical gas source; second connecting means at the dry gas passage outlet and humidified gas passage inlet for connecting the adapter with the medical liquid container, said second connecting means of the adapter and the connection-and-retention means of said container having interfitting structure including portions that permit the adapter to be manually connected to the container and integrate it as
