<p>Especially during emergencies, there is a need for laryngeal mask heads with a ventral respiration chamber (3) that has a cuff (4) which surrounds the respiration chamber and which can be adjusted in size without having to be inflated. To meet said need, the laryngeal mask head comprises non-pneumatic means (6, 7) to adjust the size in the medial-lateral direction and ventral-dorsal direction (12), which is preferably implemented by open, resilient grooves (10, 20) extending in the same direction as the cuff (4).</p> |
