Abstract
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.
