Abstract
A ventilation assembly (37) for use in ventilation of a subject using a laryngeal mask (5) comprises a head-wearable harness (39) and a pusher (41). The harness is arrangeable on the subject's head (H) for supporting the pusher against the floor of the mouth (15) of the subject (P). The pusher is arranged to displace soft tissue of the floor of the mouth in cranial direction relative to the mandible (29) of the subject for, when the laryngeal mask is installed in the airway of the subject, urging internal soft tissue of the subject against the laryngeal mask in the airway of the subject. A harness for such assembly is also disclosed.
Claims20
A ventilation assembly for use in ventilation of a subject using a laryngeal mask, the assembly comprising a head-wearable harness and a pusher,
- wherein the harness is wearable on the subject's head for supporting the pusher to press against a floor of a mouth of the subject,
- wherein the pusher comprises local elevated portions for providing a pressure in a cranial direction and a recessed portion in between the elevated portions for accommodating a portion of a throat of the subject;
- wherein the pusher is arranged, in use and operably supported by the harness on the subject, so that said elevated portions provide said pressure in the cranial direction between lateral sides of a mandible of the subject to soft tissue of the floor of the mouth of the subject and to displace said soft tissue of the floor of the mouth in the cranial direction relative to the mandible of the subject for urging internal soft tissue of the subject against the laryngeal mask in an airway of the subject as a seal to the mask when the laryngeal mask is installed in the airway of the subject.
A method of ventilating a subject comprising:
- operably installing a laryngeal mask in an airway of the subject, and
- urging internal soft tissue of the floor of the mouth of the subject against the laryngeal mask in the airway of the subject for at least partly sealing the airway and preventing leaks along the laryngeal mask using a pusher comprising local elevated portions for providing a pressure in a cranial direction between lateral sides of a mandible of the subject to the soft tissue of the floor of the mouth of the subject, and a recessed portion in between the elevated portions for accommodating a portion of a throat of the subject to urge the soft tissue of the floor of the mouth of the subject in a cranial direction of the subject relative to the mandible of the subject.
