Definitions

  • the present invention relates to an apparatus for resuscitation and a method of use thereof.
  • Cardiopulmonary resuscitation is an emergency procedure that combines chest compressions often with artificial ventilation in an effort to deliver oxygen and artificial circulation to an unresponsive person until medical help arrives. CPR is recommended for persons who are unresponsive with no breathing or abnormal breathing.
  • the artificial ventilation involves the manual provision of air to the subject by exhaling air into the subject's mouth or nose in a mouth-to-mouth or mouth-to-nose engagement.
  • CPR can also be performed on non-human animals, such as, e.g., cats and dogs.
  • the principles are virtually identical to CPR for humans except that it is recommended that artificial ventilation be provided through the non-human animal's nose and not its mouth.
  • CPR or at least artificial ventilation may be provided to a non-human animal if it is not breathing or struggling to breathe.
  • a problem in general with providing artificial respiration to a non-human animal is that it can be difficult to form a suitable engagement or contact with the mouth or nose of the animal due to different shaped anatomy.
  • a further and more common problem with providing artificial respiration to a non- human animal is that a person may be reluctant, or outright refuse, to provide artificial respiration due to a fear or reluctance to directly contact the mouth or nose of the non-human animal and/or the possible risk of infection associated with such direct contact.
  • Embodiments of the present invention provide a resuscitation apparatus for a non- human animal and method of use thereof, which may minimise or overcome at least one of the problems mentioned above, or which may provide the public with a useful or commercial choice.
  • a resuscitation apparatus for non-human animals including:
  • a barrier for location about a snout or muzzle part of the non-human animal said barrier including an opening therethrough;
  • a nose piece positioned over the opening and including one or more air receiving structures for receiving expressed air from a mouth of a rescuer and directing and/or delivering the expressed air into the nasal cavity of the non-human animal.
  • the present invention provides a resuscitation apparatus that may be readily fitted about the snout or muzzle part of a non-human to deliver artificial respiration.
  • the barrier and nose piece of the apparatus shield the rescuer from direct contact with non- human animal body fluids, such as, e.g., saliva, blood or mucus, and any risk of infection associated with such direct contact.

  • the sealing ring (320) and skirt (322) assist in at least partially preventing a flow of expressed air from escaping between the snout of the canine and the barrier (1 10). Additionally, the sealing ring (320) and skirt (322) enable the mask (100) to be comfortably fitted about the snout of the canine.
  • the mask (100) also further includes a filter (330) arranged within the opening (1 14) of the barrier (1 10) for at least partially preventing the egress of canine body fluids, such as, e.g., saliva, blood or mucus, from the nose or mouth of the canine to the mouth of the rescuer.
  • the filter (330) can be of any suitable type known in the art.
  • the filter (330) may be a 3MTM FiltreteTM hydrophobic filter.
  • the barrier (1 10) and the sealing ring (320) including the skirt (322) are permanently connected to the nose piece (130) by a uni-directional locking arrangement (350).

  • the lip (357) extends laterally outwards from the annular body (352) in a direction substantially perpendicular to the sidewall (358) to facilitate in clamping the shaped collar (1 15) of the barrier (1 10) and the sealing ring (320) at least partially against the nose piece (130).
  • the sidewall (358) of the annular body (352) and the inner surface of the sidewall (135) of the nose piece (130) each include retention members extending away from the respective sidewalls (358, 135) and configured to engage with one another to at least partially assist in permanently connecting the barrier (1 10) and the sealing ring (320) including the skirt (322) to the nose piece (130).
  • the sidewall (358) of the annular body (352) includes a resilient angled shoulder (410) extending around the exterior of the annular body (352) and the inner surface of the inner surface of the sidewall (135) of the nose piece (130) includes a corresponding resilient angled shoulder (410) extending around the inner surface.
  • Each angled shoulder (410) includes an angled outwardly facing portion (412) to enable the shoulders (410) to flex or plastically deform over one another when the annular body (352) is pressed into the receiving portion (360) of the nose piece (130).
  • Each shoulder (410) also includes a laterally extending edge portion (414), located on an opposite side of the shoulder (410) to the angled outwardly facing portion (412), to retain the annular body (352) and the nose piece (130) together once they have been pressed together.
  • the annular body (352) includes a second resilient angled shoulder (510) adjacent the lip (357) for, in use, clamping an innermost edge of the sealing ring (320) against the inner surface of the sidewall (135) of the nose piece (130).
  • the inner surface of the sidewall (135) includes a corresponding recessed portion for at least partially receiving the innermost edge of the sealing ring (320).
  • the method may include an initial step of unfolding the barrier (1 10) relative to a remainder of the mask (100).
  • the method includes fitting the barrier (1 10) of the mask (100) about the snout (910) of the canine (900) such that the snout (910) is at least partially accommodated within the barrier (1 10) and the nose piece (130) is located in front of the nose of the canine (900).
  • the air receiving structures (310) of the nose piece (130) may be optionally aligned with the nostrils or nares of the nose of the canine (900).
  • the rescuer may position his or her lips about an external surface (134) of the nose piece (130) and can commence delivering expressed air into the nasal cavity of the canine via the nose piece (130).
  • the rescuer should simultaneously press the mask (100) against the snout (910) of the canine (900) to effect a good seal about the nose of the canine and thereby minimise the escape of expressed air between the barrier (1 10) and the snout (910) of the canine (900).
