Definitions

  • the flared section produces a turbulence and reduction of velocity of the gas issuing from the tube so'as to reduce nasal burn in the patients'nostril.
  • the present invention relates to nasal cannulae which are utilized to introduce fluids, and particular gases such as oxygen, into one or both nasal passages of a patient.
  • My United States Patent 2,931,358 discloses a nasal cannula which is comprised of a pair of narine tubes and a means for holding the outlet ends of the tubes in a nares-insertable position on a patient.
  • the nasal cannula shown and described in my patent represents a substantial stepforward in the art, it does have tube'outlets which are typical of nasal cannula outlets in practice today and in practice prior to the invention disclosed in my patent.
  • nasal cannulae are utilized, there is always present the danger that nasal burn will occur in the nasal passages of a patient. Nasal burn is caused by evaporation drying of the internal walls of a nasal passage.
  • the velocity of the jet, impinging against a portion of an internal nasal passage wall may cause that portion to be so thoroughly dried that the tissue of the wall appears to have been burned with an accompanying buming sensation being sensed by the patient.
  • the present invention substantially eliminates nasal burn.
  • a further object is to provide a cannula which substantially eliminates the occurrence of nasal burn to a patient.
  • An additional object is to provide a nasal cannula which has an internally flared section adjacent its outlet end.
  • Another object is to provide a nasal cannula having an internally flared section adjacent its outlet end wherein the cross sectional area of the internal passage enlarges approximately six times in the flared section.
  • a principal object is to provide a narine tube having an outlet end, with an internally flared section adjacent said outlet end, wherein the tube has an internal diameter of approximately 0.210 inch. 7
  • FIGURE 1 is an illustration of a preferred embodiment of the present invention
  • FIGURE 2 is a cross sectional view of a portion of a conventional narine tube adjacent its'outlet end;
  • FIGURE 3 is a cross sectional view ofa section of a narine tube forming a part of the embodiment of my invention illustrated in FIGURE 1.
  • the velocity of such a jet of fluid when the fluid is a gas such as oxygen tends to quickly evaporate any moisture in its direct path in the tissues of the internal wall of a nasal passage, resulting in the aforementioned nasal burn.
  • a narine tube sufliciently flexible, it is undesirable to increase its diameter to reduce the ejection velocity of a fluid from its distal end.
  • the present invention accomplishes a reduction in the ejection velocity of the flow from the distal end of a narine tube without sacrificing the narrow diameter over most of its length or its flexibility, and thereby substantially prevents the occurrence of nasal burn.
  • a nasal cannula which has a pair of flexible plastic narine tubes 10 and 11. These tubes have respective proximal sections 12 and 13 adjacent their respective proximal ends 14 and 15 which are firmly secured in a double channel connector 16 which is illustrated inserted into the distal end of a fluid supply tube 17 which is connected through a regulator (not shown) to an oxygen tank (not shown).
  • the connector 16 provides a means for operatively joining the two tubes 10 and 11 to a single gas or fluid conveying tube.
  • narine tubes 10 and 11 pass through and are frictionally held in the respective apertures 18, 19, 20 and 21 of a bridge 22 constructed of flexible plastic tubing.
  • a section of flexible plastic tubing flexibly engages the tubes 10 and 11 to provide a slide 25 which may be manually positioned along most the the extent of the tubes 10 and 11 between the connector 16 and the bridge 22. Therefore, the bridge 22 and the slide 25 provide means for holding the outlet ends of said tubes in a nares-insertable position as is more fully described in US. Patent 2,931,358.
  • FIGURE 1 is similar to that illustrated in my US. Patent 2,931,358.
  • a pair of flared sections 26 and 27 form an integral part of the respective tubes 10 and 11 adjacent respective distal ends 28 and 2 9.
  • the ends 28 and 29 have a slightly thickened wall to in- 60 crease resistance to possible collapsing or pinching off of the ends of the tubes.
  • FIGURE 2 illustrates the structure of a conventional section 30 adjacent a distal end 31 which is typical of narine tube in use at the present time.
  • FIGURE 3 being an enlarged cross sectional view of the distal end section 26 of the tube 10, shows an internally flared section 40.
  • a stream 32 of oxygen ejected from the distal end 31 of the conventional tube 30 is straight and characterized by non-turbulence.
  • the stream 32 ejected from the conventional tube 30 may impinge directly upon the internal wall tissue of a patient and evaporate all the moisture from that tissue so that nasal burn results.
  • the flow of oxygen becomes turbulent and is ejected as a slow churning cloud which, when it impinges upon the internal wall tissue of the nasal passage of a patient, is sufficiently slow that it does not remove all of the moisture by evaporation from the tissues.
  • the tube size may be varied, it has been found that an approximate internal diameter of 0.086 inch throughout the length of the tubes and 11 combined with a wall thickness of approximately 0.022 inch provides a very flexible plastic tube.
  • the internal diameter is increased from 0.086 inch to an internal outlet end diameter of approximately 0.210 inch.
  • the internal passage cross-sectional area enlarges almost six times in the flared section.
  • the expansion causes a number of small turbulent eddies to form.
  • the length of the flared section 40 is approximately 1.125 inches and extends from a point where the uniform internal diameter of approximately 0.086 inch ends and runs to the outer end of the section 40 where the internal diameter is equal to approximately 0.210 inch.
  • the internal cross-sectional area of the flared section 40 increases 6 to 1 over a distance of from 12 to 14 times the uniform internal diameter of said tube 10 or 11.
  • the wall thickness of the end 28 is increased from 0.022 inch to a thickness of approximately 0.026 inch at the outlet end 28.
  • the flared end section 27 is identical to the flared end section 26.
  • the internally flared section 40 provides an internal passage whose cross-sectional area enlarges approximately six times in the flared section.
  • This velocity is sufficiently reduced that it cannot evaporate all of the moisture from the tissue and nasal burn is prevented.
  • the outer diameters of the tube ends 28 and 29 are only approximately one quarter of an inch.
  • a cannula has been illustrated and described, which provides a narine tube for each nostril of a patient, only a. single tube may be desired in some applications. Thus, it would not be necessary to join both tubes to a distal end of a gas supply tube such as 17. Further, where only one tube is utilized, the requirement for means of holding the distal end of a tube in a nares-insertable position composed of the bridge 22 and the slide may not be required. All such modifications are intended to be within the scope of the appended claims.
  • a nasal cannula for use in administering gas under pressure through the nasal passages comprising:
  • a nasal cannula for use in administering gas under pressure through the nasal passages comprising a narine tube having an inlet end, an outlet end and an internally flared section adjacent said outlet end, said internally flared section having a length of approximately 1.125 inches, said tube having an internal diameter of approximately 0.086 inch, an internal outlet end diameter of approximately 0.210 inch and a wall thickness of approximately 0.022 inch increasing in said flared section to approximately 0.026 inch at said outlet end.
  • a nasal cannula for use in administering gas under pressure through the nasal passages comprising:
  • narine tubes each having an inlet end, an outlet end and an internally flared section adjacent said outlet end and having a length of approximately 1.125 inches, said tubes having an internal diameter of approximately 0.086 inch and an internal outlet end diameter of approximately 0.210 inch, and
  • a nasal cannula for use in administering gas unde pressure-through the nasal passages comprising:
  • narine tubes each having an inlet end, an outlet end and an internally flared section adjacent said outlet end, said tubes having an internal passage cross-sectional area which enlarges approximately six times in said flared section,
  • said tubes having an internal diama narine tube, having an inlet end, an outlet end and an internally flared section adjacent said outlet end, said tube having an internal passage cross-sectional area which enlarges approximately six times in said flared section,
  • said flared section having a length within the range of twelve to fourteen times the diameter of said internal passage
