Embodiment Construction

[0077] It is to be understood that the drawings are intended to show preferred embodiments of the invention. It will be understood that the invention should not be considered limited to all the features shown in these drawings.

[0078] now refer to Figure 1 to Figure 6 , which show various views of a device 10 according to the invention, it can be seen that the device 10 comprises a cover 12 . A ventilation conduit 14 is connected to or formed with the mask such that the distal end of the ventilation conduit opens into a ventilation chamber 16 formed on the laryngeal side of the mask. The ventilation conduit 14 may be a flexible hose. Alternatively, it may be a rigid tube formed to facilitate insertion and positioning of the device into place in the patient. The ventilation catheter 14 enables gas to be provided to the larynx and trachea when the device has been properly inserted into the patient. Gases provided to the larynx and trachea may include anesthetic gases, oxy...

Abstract

A device (10) for maintaining an airway in a patient comprises a mask (12), the mask having a resilient conformable peripheral portion (20, 22) shaped such that the mask (12) forms a seal with the larynx when the mask is positioned in the laryngo pharynx to thereby prevent ingress of extraneous fluids into the larynx, the peripheral portion (20, 22) of the mask defining at least one cavity (32, 34) for providing fluid communication to the oesophagus when the mask is inserted into the laryngo pharynx, and an airway tube (14) connected to or formed with the mask for passing gas to the larynx when the mask is properly inserted into the laryngo pharynx. The airway tube (14) preferably is curved as it leaves the mask.

Description

technical field [0001] The present invention relates to devices for maintaining ventilation in a patient. In a preferred embodiment, the invention relates to a laryngeal mask. Background technique [0002] During surgical procedures under general anesthesia, maintaining continuous ventilation is critical to patient safety. For many years, continuous ventilation during this surgical procedure was achieved by inserting an endotracheal tube into the patient. An endotracheal tube is usually inserted through the mouth or nose into the larynx, past the vocal cords and into the windpipe. Difficulty is often encountered in correct positioning of the endotracheal tube because the endotracheal tube must be inserted through the vocal cords. [0003] British Patent No. 2111394 (which corresponds to US Patent No. 4509514) describes a device for maintaining ventilation in a patient. The device is described as an artificial ventilation device. The device consists of a curved, flexible...
