A gastro-laryngeal mask features softly compliant construction of the distal half of the mask, wherein the mask is of generally elliptical configuration, with an inflatable peripheral cuff to seal and support the mask around the laryngeal inlet. A back cushion is inflatable to engage the back wall of the pharynx and thus to forwardly load the peripheral-cuff seal to the laryngeal inlet. An evacuation tube for external removal of a possible gastric discharge completes an evacuation or discharge passage contained within the mask and opening through the distal end of the peripheral cuff. Special provision is made for assuring integrity of the discharge passage within the flexible distal half of the mask, i.e., assuring against collapse of the distal-end half of the softly compliant evacuation tube in the distal region of the mask, such that inflation of the mask does not compromise viability of the evacuation tube by compressing softly compliant material of the evacuation tube during periods of mask inflation. The special provision also favors such collapse of the mask when deflated as to provide a leading flexible edge for piloting a safe and correct advancing insertional advance of the deflated mask in the patient's throat, in avoidance of epiglottis interference and to the point of locating engagement in the upper sphincter of the oesophagus.

To assess the sensitivity of a subject's pharynx, an open mouthpiece (1) fitted with a thin guide tube (2), having an articulated end (4), is inserted into the subject's mouth. A pipe (9) is inserted into the guide tube, under visual observation through the mouthpiece, until it touches the subject's palate. The position on a measurement scale (11) provided on the pipe facing a second end of the guide tube is noted, and the pipe is withdrawn over a preset distance, for example 1 cm, and fixed in this position onto the guide tube. A variable gas flow is injected into the pipe and reaches the pharyngeal mucous situated facing the pipe. The sensitivity of the subject's pharynx, measured by the threshold of sense perception, is determined by the lowest flow value perceived by the subject.

The present invention is the universal unmedicamental system to treat the snore and obstructive sleep apnea and recover of the normal breathing during sleep. The invention includes the device, which ensures the fixation of the tongue in a putting forward beyond the mouth position. As a result, the tongue's pharyngeal part pushes forward in the mouth, releasing besides the throat and excluding the tongue from a system of obstruction to the air's passing through the throat. This increases the throat's capacity, depriving the other throat's structures of the possibility to provoke the partial or complete obstruction to the air's passing through the throat during the physiological process of breathing in the time of the sleep.

The present invention relates to methods for assessing swallowing motor function in a subject. The methods rely on obtaining intraluminal impedance and pressure measurements from the pharynx and/or esophagus of the subject during clearance of a bolus from the mouth and/or throat of the subject. The intraluminal impedance and pressure measurements are combined to derive a value for one or more pressure-flow variables in the pharynx and/or esophagus of the subject. The value of the one or more pressure-flow variables is compared to a predetermined pharyngeal and/or esophageal reference value for the one or more pressure-flow variables in order to provide an assessment of swallowing motor function in the subject. The intraluminal impedance and pressure measurements can also be combined to generate a swallow risk index for the subject or to generate an obstructive risk index for the subject based on a combination of a value of more than one pressure-flow variable in the pharynx and/or esophagus of the subject. In this way, swallowing motor function in the subject can be assessed by comparing the swallow risk index or obstructive risk index for the subject to a predetermined reference swallow index or predetermined reference obstructive index, respectively. Products which make use of these methods are also encompassed by the present invention.

The invention discloses snore stopping liquid and a preparation process thereof. The snore stopping liquid is prepared by the following components in percentage by weight: 1 to 3 percent of tween80, 0.5 to 15 percent of glycerin, 0.5 to 1.5 percent of sodium chloride, 0.3 to 0.8 percent of sodium edentate, 0.1 to 0.3 percent of potassium sorbate and 80 to 90 percent of purified water.
