Ventilation assistance device

A ventilation assembly for use in ventilation of a subject using a laryngeal mask comprising a head-wearable harness and a pusher,

• wherein the head-wearable harness is arrangeable on a head of the subject for supporting the pusher to press against the floor of the mouth of the subject,
• the pusher is generally U-shaped in a transverse direction, comprising a bridge in a front portion for, in use and operably supported by the head-wearable harness on the subject, accommodating a tissue located at a submental triangle of the subject, and laterally opposing legs extending rearward from the bridge in a rear portion, wherein the bridge extends for ⅓ to ¼ of a pusher length from a front end of the pusher;
• the legs comprise laterally opposite protrusions arranged in a position dorsal to the bridge and wherein the protrusions provide a space between them having a shape generally flaring in a cranial direction in use to displace, in use and operably supported by the harness on the subject, soft tissue of the subject at a left and a right submandibular triangles in the cranial direction relative to a mandible of the subject and surrounding tissue of the subject's the submental triangle, when the laryngeal mask is installed in an airway of the subject, urging internal soft tissue of the subject against the laryngeal mask in the airway of the subject, and
• each protrusion is hollow providing a recess at a bottom side of the pusher, for accommodating an operators' finger so as to facilitate manipulation and placement of the pusher.
