Problems solved by technology

If the seal around the laryngeal entrance provided by the cuff is disturbed, airway patency may be compromised and gastric fluid may be drained
This is particularly problematic when treating pediatric patients (although not exclusively), because even small unintentional movements, such as the proximal end of the airway device, can be critical due to the small size of the airway device and the patient. hood and its seal interfere with

Embodiment Construction

[0078] In the description of the exemplary embodiments described below, like parts will be given the same reference numerals throughout the description.

[0079] For ease of explanation, refer to Figure 1 to Figure 4 , reference sign A denotes the dorsal surface of the device. Reference sign B denotes the ventral surface of the device. In accordance with standard practice, the part of the device 1 which in use extends from the patient is referred to herein as the proximal end (in the sense that it is closest to the user), while the other end is referred to as the distal end. exist figure 2 In , reference sign C indicates the right side, and reference sign D indicates the left side.

[0080] Referring to the drawings, there is shown an artificial airway device 1 for assisting ventilation of the lungs of a patient, the device comprising: an airway tube 2 having an airway tube lumen 3; a mask 4 at one end of the airway tube, the The mask comprises a back plate 5 and has a p...

Abstract

An artificial airway device (1) to facilitate lung ventilation of a patient, comprising an airway tube (2) including a lumen (3), a mask (4) at one end of the airway tube, the mask including a backplate (5) and having a peripheral formation (6) capable of forming a seal around the circumference of the laryngeal inlet, the peripheral formation surrounding a hollow interior space or lumen (7) of themask and the airway tube (2) opening into the lumen of the mask, the device further comprising fixation means (8c) for fixation of the device to a patient when the device is in use, the fixation means being movable with respect to the airway tube to allow for correct positioning of the device with respect to the anatomy of the patient.

Description

technical field [0001] The present invention relates to an improved artificial airway device, in particular to a laryngeal mask suitable for use in the treatment of pediatric patients. Background technique [0002] For at least seven decades, an endotracheal tube, comprising an elongated tube with an inflatable balloon positioned near the distal end of the tube, has been used to establish the airway in unconscious patients. In operation, the distal end of the endotracheal tube is inserted through the patient's mouth into the patient's trachea. Once in place, the balloon is inflated to form a seal with the interior lining of the trachea. After this seal is established, positive pressure can be applied to the proximal end of the tube to ventilate the patient's lungs. Also, the seal between the balloon and the tracheal lining can protect the lungs from aspiration of foreign matter (as the seal prevents material regurgitated from the stomach from being aspirated into the patie...
