Abstract: A laryngeal mask including a rigid hollow tube essentially in the form of a “J”, and which has a lengthwise opening along its entire length, and a flexible tube, also essentially in the form of a “J”, configured to be housed in the lengthwise opening of the rigid hollow tube, and which can be separated from it. This provides a configuration for a laryngeal mask that can change from having rigid properties to flexible ones at the doctor's will, without the need to interrupt the patient's supply of oxygen at any time.

Abstract: A device (1) for the ventilation of a human being or animal which comprises a dome (2) having a cavity (2a), which dome (2) is attached to a laryngeal ring (3) for sealing the human being or animal's internal airways, at least one oxygen tube (4) that connects to the cavity (2a) of the dome (2), for allowing oxygen or gases to enter or leave the human being or animal's internal airways and at least one laryngeal aspiration tube (5), different from the oxygen tube (4), that also connects to the cavity (2a) of the dome (2), for allowing air and/or secretions to leave the human being or animal's internal airways.

Abstract: A laryngeal mask that comprises a first element which is a rigid hollow tube essentially in the form of “J”, and which has a lengthwise opening along its entire length, and a second element that comprises a flexible tube, also essentially in the form of a “J”, intended to be housed in the lengthwise opening of the first element, and which can be separated from it. This provides a configuration for a laryngeal mask that can change from having rigid properties to flexible ones at the doctor's will, without the need to interrupt the patient's supply of oxygen at any time.
