Especially during emergencies, there is a need for laryngeal mask heads with a ventral respiration chamber that has a cuff 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 structures to adjust the size of the mask head in the medial-lateral direction and the ventral-dorsal direction, which are preferably implemented by open, resilient channels extending in the same direction as the cuff.Mevcut buluş dorsal olarak düzenlenmiş bir kapatıcı plakaya ve bununla bağlı bir supraglottik tüpe sahip olan bir larengeal maske başı ile ilgilidir, burada larengeal maske başı bir ventral solunum alanını çevreleyen bir manşete sahiptir.
