Definitions

  • ABSTRACT A flexible nasal cannula adapted for the intake of therapeutic gas from either the right or left side of a patient, wherein the top and bottom wall sections of the cross tube are tapered from the ends to the mid point of the cross tube.
  • This invention relates to nasal cannulas. More specifically, it relates to flexible'nasal cannulas adaptable for use from either the right or left side of a patient.
  • FIG. 1' is a cross'sectional view of, the nasal cannula of thisinvention.
  • FIG. 2 is a cross sectional view of the cannula of FIG. I through the lines 2-2.
  • FIG. .3 is a cross sectional view of the cannula of FIG. l through the lines-3-3.
  • FIG. 4- is a top view of the cannula of FIG. 1.
  • FIG. 5 is a fragmented view of a-preferred embodiment of the cannula of this invention.
  • this invention provides a flexible nasal-cannula adapted forv the intake of therapeutic gases from either the. right'or left side of; apatient, which corn prises. across tube in flow communication' with nostril; conduits, whereinthe top and bottom IWKIIJ-SCCIIOI'IS of the cross tube are taperedfrom both'ends'to the mid section of' the cross tube.
  • FIG. I-there isdepicted' a nasal cannula lo'ofthis'invention, having a cross-tube II, nostril conducts I2 and 13 with orifices l4.and'l6.
  • the flexibility of the cannula of this invention is providedv by a tapering: of the upper'section A and 'thebottom section Bofthe wallof the-cross tube 11, such that the thickness of section A and section B varies from'the end .I7-t0 the mid-'section1l8of'the cross tube 11: This isillustrated in FIG. l-at land in FIGS. 2 and 3. In FIG.
  • the thickness of'the upper section A of thewall of" cross tube 1-1 is greater than that'of the lower section I ⁇ , while in FIG. 3 the thickness of wall' sections Aand B:of the cross tube are reversed, such that section B isthicker than section A.
  • This variation in thickness of sections A and B through'cross tubell is shown in crosssection in FIG. I, by the-area designated as Z.
  • the thickness of'side wall section-C of crosstube is not ti'i pcrcd and is a constant dimension from end [7 to the mid point I8, and also the inside diameter of-thebore thickness of wall sections A and B vary along their respective lengths from end 17 to mid section 18 bya ratio of about 3 to I for section A and about I to 3 for section B. That is section A is about 3 times as thick at end I7 as it is at mid section 18, and section B is about one-third as thick at end 17 as it is a mid section 18.
  • a gas inlet tube may be in flow communication with bore 19 at either end of cross tube 11.
  • the inlet gas tube 21 is shown in phantom at the left side of cannula 10 in flow connection with bore I9 of cross tube 11.
  • the open end of bore I9 may be closed with a plug 22, shown in phantom in a closed and open relationship with bore 19 on the right side of cannula l0.
  • Plug 22 may be attached to a strap tab 23 or may be unattached to cannula 10.
  • FIG. 5 A preferred embodiment of the flexible nasal cannula of this'invention is shown in FIG. 5, whereinwthe right end'of the bore 19 of cross tube 11 of cannula 10 is sealed. It is understood that either end of bore I9 of cross tube Il may be sealed and that the right endis shown sealed in FIG. 5 for purpose of illustration and not limitation.
  • Strap tabs 23 and 24 are illustrative of the type of tabs that may be incorporated into the cannula 10, and other strap tabs will become apparent to those skilled in the art. The only limitation upon'the type of strap tab that may be used is that it should not interfere with 'the flexibility of the cannula.
  • FIG. 4 The flexibility of the cannula of this invention is illustrated in FIG. 4 where in the curvature of the cannula 10 in relation to a patients face is shown in phantom.
  • section A being thinner than section B at the mid section of cross tube II e.g. between conduits I2 and 13, allows the conduits I2 andl3 to incline toward each other where the cannula I0 is curved'to fit a patient in the manner shown in phantom in FIG. 4.
  • the conduits l2 and 13 thus adjust to fit the nasal passages of a patient.
  • the nasal cannula of this invention may beprepa re 'd from polymeric material such as polyvinylchloride.”
  • A'flexible nasal cannula comprising in combination a cross tube, a pair of generally parallel upstanding nostril conduits in flow communication with said cross tube, a strap tab mounted at about each end of said cross tube, a plug mounted on one of said straptabs'at' oneend ofsaid-cross tube, said 'plug b'eingremovablly and sealingly inserted in said one end, an inlet tube in flow communication with said cross tube end opposite.
  • said cross tube having upper, lowerv and sidewall sections, said nostril conduits extending from said upperwall section.
  • said cross tube having said upper and lower sections of its walls tapered from each end to the midsection, such that the thickness of the upper section is greater at the ends than at the mid-. section and the thickness of the lower section is greater at the midsection than at the ends, and the side walls of said cross tube are of uniform thickness from end to end.
  • a flexible nasal cannula comprising in combination a cross tube having a closed end, a pair of generally parallel upstanding nostril conduits in flow communication with said cross tube, a strap tab mounted' at about each end of said cross tube, an inlet tube in flow 4 is greater at the ends than the midsection and the thickness of the lower section is greater at the midsection than at the ends, and the side walls of said cross tube are of uniform thickness from end to end.
