  • the invention concerns a respiration aid for administering gas to a victim, comprising a gas container, a gas inlet for allowing gas to enter into the container, and a gas outlet for allowing gas to be released from the container for administration to a victim.
  • the invention concerns a respiration aid to be operated by laymen.
  • the invention also concerns a method for administering gas to a dummy or test person using a respiration aid.
  • the invention furthermore concerns a method for administering gas to a victim using a respiration aid.
  • Respiration apparatuses are known from practice and usually comprise a balloon unit, provided with an inlet valve, for allowing ambient air into the balloon unit, and provided with a respiration channel for connection with a patient to whom artificial respiration is to be applied, which respiration channel is provided with a check valve for allowing ambient air to flow from the balloon unit via the respiration channel to the patient upon squeezing the balloon unit, and which respiration channel is further provided with an evacuation valve, which at rest is held in an open position by the action of a spring, for evacuating air exhaled by the patient via the respiration channel to the environment.
  • the respiration channel may be connected to a face mask, which is preferably provided over the mouth and nose of the patient using bands or elastic straps.
  • the respiration channel may be connected to a tube which is inserted into the airway, such as a laryngeal mask.
  • An air tight connection is required between the patient and the face mask and/or the inserted tube in order to prevent leakage of the displaced air to the environment.
  • Additional tubing may be provided between the respiration channel and the face mask or inserted tube, allowing the bellows to be placed at a distance from the mouth and nose of the patient.
  • the balloon unit comprises a resilient bellows.
  • the pressure in the bellows is increased and a volume of air enclosed by the bellows is displaced from the bellows via the check valve through the respiration channel to the patient.
  • the increased pressure in the respiration channel forces the evacuation valve against the action of the spring in a closed position.
  • the bellows rebounds to the starting position, closing the check valve while allowing ambient air to be sucked in via the inlet valve.
  • the spring force induces the evacuation valve to return to an open position, allowing the exhaled air to flow from the patient to the environment.
  • Such a manually operated respiration apparatus is known to a skilled person by the name of resuscitator and is used by trained professionals, such as paramedics, for manually applying artificial respiration to persons or animals, for instance during reanimation.
  • a respiration apparatus has a simple construction and can easily be transported. Further, the apparatus has a high reliability, while a minimum of maintenance is required.
  • Such known apparatuses however have an adjustable volume and/or an adjustable maximum inspiration pressure which may make operation by laymen difficult and/or dangerous.
  • Laymen lack the medical knowledge and training required for adjusting the pressure and/or volume settings of such a respiration apparatus.
  • laymen have little or no experience and/or training in feeling the volume which is administered to a victim when operating such a respiration apparatus.
  • Such known respiration apparatuses are not normally available to laymen having no more than Basic Life Support (BLS) qualification and skills, whereas the main concern of these laymen when involved in a resuscitation attempt is the risk of infection during mouth-to-mouth resuscitation.
  • Laymen typically may come into action when there is no professional assistance available, or available yet, and may act on a person being a victim or a casualty for instance from malfunctioning of the own body, e.g. a heart attack, or from an accident.
  • respiration apparatuses have no integrated PEEP function, which is for example required for resuscitation of a drowning victim as described in trauma protocols, or for resuscitation of a neonate with meconium aspiration as described in partus protocols.
  • a goal of the invention is therefore to provide for an alternative respiration aid to be operated by laymen that may solve at least one of the above disadvantages.
  • Another goal of the invention is to provide a respiration aid incorporating the guidelines documented in the protocols of most international resuscitation councils.
  • Another goal of the invention is to provide a respiration aid that may be operated handsfree.
  • a respiration aid according to claim 1. It has been found that by providing a respiration aid with two relatively rigid walls, connected by a pliable wall, the volume of gas being administered can be controlled in a better way. By pressing the two rigid walls towards each other a continuous and relatively even gas release can be obtained, allowing for a better dosing of the volume of gas being administered. In particular, a layman can easily and reliable operate the respiration aid. A laymen only has to bring the two relatively rigid walls together to release gas from the gas container towards the victim, and then simply may let the walls go to let the gas container inflate itself.
  • each time moving the wall together and letting the walls go the same constant predetermined volume and predetermined pressure is obtained. Also, by providing a safety valve to allow an excess pressure to be released from the container, the operation of the respiration aid by a layman may be reliable and safe.
  • the positions of the relatively rigid walls of the gas container are predetermined. In a first position, at least a part of the walls are at a distance of each other. The gas container is then filled with gas. In a second position, the walls are adjacent each other, the gas is then released from the gas container. By moving the walls between the first and the second position a constant predetermined volume and pressure is provided. By repeatedly moving the walls between the first and the second position, each time the same constant predetermined volume and pressure is provided, making the respiration aid suitable for operation by a layman.

  • the walls 3, 4 are adjacent each other, as shown in Fig. 4B, and gas has been released from the gas container 2.

Each time when moving the walls from the first position to the second position by bringing the walls towards each other a constant predetermined volume of gas is released from the gas container to the victim.
  • the gas container is filled with a constant predetermined volume of gas. Therefore, independent of the technique used by the layman to move the walls, e.g. by using a hand, a knee or a foot, the volume filled in the gas container and released by the gas container is the same and remains constant.
  • the predetermined volume is fixed.
  • different sizes of respiration aids may be provided each having a fixed volume for use in different calamities by laymen. It can be understood that for an adult victim a different volume and/or pressure may be required than for a child victim, or that for a drowning victim a different volume and/or pressure may be required than for a victim suffering a heart attack.

  • a coiled spring (not shown) may be provided that is connected to the rigid walls 3, 4, preferably to the centre thereof.

  • the pliable wall 5 may for example be bellows shaped.
  • the pliable wall 5 may comprise relatively flexible material.
  • the pliable wall 5 may for example be a pliable bag that is connected between two rigid walls 3, 4.

  • the safety valve may prevent the victim's lungs from being inflated with too much air, for example when the rigid walls 3, 4 are pressed too hard and/or too fast, which could damage the lungs of the victim.
  • the safety valve is arranged to release some of the pressurised air from the container 2, if the pressure in the container 2 is too high, for example due to resistance in the lungs of the victim. Meanwhile, the lungs of the victim may still be ventilated through the gas outlet 7 A, at a more convenient pressure.
  • the maximum threshold pressure for releasing air from the container 2 may for example be predetermined by the characteristics of the safety valve that is provided in the respiration aid 1. By providing a safety valve with a predetermined pressure threshold, the respiration aid 1 can be operated safely by a layman minimizing the risk of damaging the lungs of the victim.
  • Preferred safety valves may be selected according to the purpose of the respiration aid 1.
