Definitions

  • FIG. 1A illustrates a crown-centered strap 100 in conjunction with an exemplary nasal respiratory device 104.
  • FIG. 1B illustrates the crown- centered strap 100 of FIG. 1A in conjunction with an exemplary nasal respiratory circuit, which may include, for example, a nasal respiratory device 10 and ventilation bag 112, manual resuscitator, or a continuous or intelligently-controlled gas supply (not shown).
  • the device may include end-tidal sampling 116 and/or instrumentation.
  • the present invention is directed to strap for use with nasal respiratory or other devices that obviates one or more of the problems due to limitations and disadvantages of the related art.
  • this disclosure in one aspect, relates to a strap having a nape strap, that, when worn, passes behind the neck of a patient and lies nominally along and X – Y plane, running behind a nape of a patient’s neck and attaches to the + X and -X face of the face mask.
  • the strap assembly may further include a bridge strap that lies nominally along the Y-Z plane over a nasal bridge of the patient and attaches to the nape strap.
  • the disclosure relates a method for applying a face mask with the strap assembly to a person’s face.
  • FIG. 1A illustrates a crown-centered strap in conjunction with an exemplary nasal respiratory device.
  • FIG. 1B illustrates the crown-centered strap of FIG. 1A in conjunction with an exemplary nasal respiratory.
  • FIGs. 2A, 2B, 2C, and 2D illustrate an example of a nape strap according to principles described herein.
  • FIGs. 3A, 3B and 3C illustrate a head strap as described herein in combination with an example nasal respiratory device and/or respiratory circuit.
  • FIGs. 4A, 4B, 4C and 4D illustrate a nape strap according to principles described herein in combination with an example nasal respiratory device and/or respiratory circuit.
  • FIG. 5 illustrates connectors for use with a nape strap according to principles described herein. DETAILED DESCRIPTION [0018]
  • FIGS. 1A and 1B A nasal respiratory mask/device (such as the XChangeTM device shown in the figures) with a crown-centered head strap 100 configuration and cartesian coordinate system are illustrated in FIGS. 1A and 1B. The views of FIGs.
  • FIG. 1A and 1B show a right strap 120 (on the right side of the patient’s head 101), and a complementary left strap (on the left side of the patient’s head) is not shown.
  • the head strap 100 to a +X and -X face 124 of the nasal respiratory mask 104 is at an angle ⁇ relative to the Y axis centered over the crown of the head 101.
  • the left strap and the right strap 120 are under tension, each providing a force F Strap .
  • FIGs. 2A-2D To reduce the likelihood that a circuit load in the negative Z direction will break the seal, a new strap design is shown in FIGs. 2A-2D.
  • the illustrated strap assembly 203 includes a Nape Strap 228, a bridge strap 234 and a load transmission strap(s) 238.
  • the nape strap 200 that lays nominally along the X – Y plane, running behind the nape of the patient’s neck 205 and attaches to the + X and - X face of the nasal respiratory mask (not shown) by being inserted through a loop slot on each side of the nasal respiratory mask.
  • FIGs. 2A and 2B illustrate a perspective view of a nape strap 200 as worn by a patient 101 according to principles described herein.
  • the nape strap 228 may be attached to the respiratory device 104 via slots and/or rings 240, and folded back over on itself, attaching with hook and loop material (not shown), as illustrated in FIGs. 2A and 2B. In an alternative aspect, the nape strap 228 may connect back to itself via an adhesive, which may be removable/repositionable.
  • FIG. 2D illustrates an example attachment of a bridge strap according to principles described herein.
  • the Bridge Strap 234 lies nominally along the Y-Z plane.
  • the bridge strap 234 attaches to the respiratory device 104, for example, to the gas port 207 via a Device-Bridge Strap Slot interface 250. As illustrated in FIG.
  • the strap slot interface 250 may be a hook 246 that hooks around a profile/circumference the gas port 207.
  • the hook 246 may be further secured to the gas port by a latch or hook (not shown).
  • a slot or other attachment mechanism may be mounted on the nasal respiratory device 104 or the gas port 207 for receiving the hook 246 or other attachment mechanism on the bridge strap 234.
  • the bridge strap 234 may attach to the gas port 207 of the nasal respiratory mask 104 with a strap ring 248 that includes the Device- Bridge Strap Slot interface shown in FIGs. 4A-C.

Abstract

La présente invention concerne un ensemble sangle pour un masque facial qui comprend une sangle de nuque, une sangle de transition et au moins une sangle de transmission de charge. La sangle de nuque repose nominalement sur le plan X - Y, passe derrière la nuque du patient et s'attache aux faces + X et - X du masque respiratoire nasal par insertion dans une fente en forme de boucle de chaque côté du masque respiratoire nasal. La sangle de transition passe au-dessus de la tête du patient et s'attache à la sangle de nuque à l'arrière du cou du patient.
