Definitions

  • the present invention relates to an apparatus for removing an object lodged within a trachea of a person.
  • the basic maneuver to dislodge objects lodged within the air passageway of a person is referred to as the Heimlich maneuver.
  • the person conducting the maneuver must stand behind the victim and wrap his/her arms around the choking victim.
  • the person conducting the maneuver places his/her thumb against the victim's upper abdomen, above the naval but below the breast bone.
  • the hands are clasped together and the person pulls forcefully into the abdomen with a quick upward and inward thrust.
  • the purpose is to push air from the lungs up into the windpipes to dislodge the stuck object.
  • the maneuver is repeated several times until the object is dislodged.
  • the person conducting the maneuver must be capable of holding the person up while conducting the maneuver properly. If he or she is not capable, then the choking victim is laid on his/her back as the person conducting the maneuver straddles the choking victim. The heel of the hand is placed on the abdomen of the choking victim with the other hand on top of the first hand to perform a quick forceful push. Once again the procedure attempts to push air out of the lungs and through the windpipe to dislodge the foreign object.
  • Another maneuver is to hold the person's tongue with one hand while reaching in with two (2) fingers to remove the lodged object.
  • the danger is that the lodged object would be pushed further down into the throat.
  • the above maneuvers may be ineffective and are also complicated by the fact that the choking victim may be unconscious and/or unable to position his/her body in the upright position.
  • the present invention specifically addresses the issues identified above, discussed below and those that are known in the art.
  • the apparatus may include a semi-rigid tube that can conform to a shape of the air passageway of the person and not collapse when a vacuum is applied to the tube.
  • an inflatable ring may be attached at the end of the tube.
  • the inflatable ring has a central through hole which is in fluid communication with a lumen of the tube.
  • the tube is also in fluid communication with the vacuum source that applies a vacuum pressure to the tube as well as the lumen of the inflatable ring.
  • the inflatable ring is initially deflated. While deflated, the inflatable ring is inserted through the air passageway of the person choking on an object. Once the ring is positioned within the air passageway of the choking victim, the inflatable ring is inflated to form a seal about an inner surface of the air passageway of the person.
  • the vacuum source applies a vacuum to the tube and the lumen of the inflated ring.
  • the vacuum urges the object stuck in the air passageway of the choking victim through the lumen of the inflated ring and into the tube.
  • the inflatable ring is deflated and removed from the air passageway of the person. The person can now breathe normally.
  • the apparatus may comprise an inflatable ring, a tube, and a vacuum source.
  • the inflatable ring may be sized and configured to be insertable into the air passageway of the person when the ring is deflated. After insertion, the inflatable ring may form a seal with an interior surface defining the air passageway when the ring is inflated.
  • the ring may have a central hole that is in fluid communication with the lower portion of the air passageway of the person when the ring is inserted into the air passage way and inflated.
  • the tube may be in fluid communication with the central hole of the ring.
  • the vacuum source may be attached to and in fluid communication with the tube for providing suction to the lower portion of the air passageway of the person for moving the object from the lower portion of the air passageway, through the central hole and through the tube to remove the object from the lower portion of the air passageway of the person.
  • the ring may define an inner periphery.
  • the apparatus may further comprise a fitting which defines first and second end portions. The first end is attached to the tube and the second end has an opening which matches the inner periphery of the ring to maximize the size of the object that can be removed from the air passage of the person.
  • the ring may have an oval shape.
  • the apparatus may further comprise a mechanical pump in fluid communication with the ring for inflating the ring and a valve disposed between the pump and the ring for maintaining or releasing gas in the ring.
  • the pump may be a bulb.
  • the vacuum source may be a syringe, pump or vacuum.
  • a method of removing an object from a lower portion of an air passageway of a person may comprise the steps of inserting a deflated ring into the air passageway of the person; inflating the ring; forming a seal between the ring and the interior surface of the air passageway; positioning a central hole of the ring to be in fluid communication with a lower portion of the air passageway of the person; and applying a negative pressure to a tube in fluid communication with the central hole of the ring to dislodge and remove the object located at the lower portion of the air passageway.
  • the applying the vacuum step may comprise the step of actuating a syringe, pump or vacuum to induce the negative pressure to the tube.
  • the inflating the ring step may comprise the step of actuating a pump in fluid communication with the ring until the desired seal is established.
  • the method may further comprise the step of closing a valve disposed between the pump and the ring to maintain pressure within the ring.

  • the apparatus 10 may comprise an inflatable ring 18 that may be inserted into the air passageway 14 of the person 16.
  • the inflatable ring 18 has a central lumen 20 which can be positioned in the person's air passageway so as to be in fluid communication with the air passageway 14 of the person 16 when the apparatus 10 is in use.
  • the lumen 20 is in fluid communication with a tube 23 that extends from the inflatable ring 18 and out of the person's mouth.
  • the inflatable ring 18 can form a seal about an interior wall 24 of the air passageway of the person 16. After the seal is formed, a vacuum may be applied to the tube 22 to remove objects lodged in the air passageway (e.g. trachea) of the person and out of the tube 22. After removal, the inflatable ring 18 is deflated and the apparatus 10 is removed from the air passageway of the person. The apparatus or certain components thereof can be thrown away and a new clean apparatus 10 used the next time. Alternatively, the apparatus can be sterilized for subsequent use.
  • the inflatable ring 18 may be fabricated from a flexible latex, plastic, or rubber material.
  • the inflatable ring 18 may have an oval or doughnut shape which forms a circular ring configuration with a central through hole or lumen.
  • the inflatable ring 18 may be sized such that when deflated, the inflatable ring 20 can be inserted through the air passageway of the person.
  • the outer peripheral portion 22 of the inflatable ring 18 forms a generally air tight seal with the inner wall 24 of the air passageway.
  • a pressure differential exists between the downstream and upstream sections of the air passageway with respect to the object 12 lodged in the air passageway 14 (e.g., trachea) of the person 16 to force the object in toward the ring 18.
  • the ring 18 may be connected to a pump 26.
  • the pump 26 may be squeezed repeatedly to force air or other gas into the ring 18 to inflate the same.

  • the second opening 38 receives the tube 22 and forms an airtight seal therebetween.
  • the tube as well as the fitting 32 are semi-rigid so that the tube 22 and fitting 32 do not collapse upon application of a vacuum yet are flexible enough to be bent or flexed to conform to the shape of the air passageway of person 16.
  • a vacuum source 40 may be connected to the proximal end of the tube 22 to provide negative pressure to the lumen 20 of the inflatable ring 18. When the negative pressure is applied, objects lodged within the air passageway are urged toward the lumen 20 of the ring 18 and out of the air passageway.
  • the vacuum source may be a syringe 42, pump 43 or a vacuum 44.
  • the inflatable ring is inserted through the mouth of the person, down through the throat and past the epiglottis until a distal end 50 of the ring 18 is in the base of the throat lying against the upper end of the normally closed oesophagus.

Abstract

La présente invention concerne un tube semi-rigide relié à un anneau gonflable et à une source de vide. Ledit anneau gonflable peut être introduit dans le conduit permettant le passage de l'air formé par la trachée d'une personne, puis gonflé pour former un joint étanche contre la surface intérieure de la trachée de la personne. Un trou traversant situé au centre de l'anneau est en communication fluidique avec le tube, ainsi qu'avec la partie de la trachée de la personne située sous l'anneau. La source de vide applique une dépression au niveau du tube, du trou traversant situé au centre de l'anneau, ainsi que de la partie de la trachée de la personne située sous l'anneau, pour extraire les objets coincés dans la trachée de la personne. Une fois l'objet coincé extrait de la trachée, l'anneau peut être dégonflé et le tube/anneau peut être retiré de la trachée de la personne afin que celle-ci puisse à nouveau respirer normalement.
