The present invention comprises an insufflated air inlet (2a), an outlet (3a) for said insufflated air provided at the lower end of an air conveying tube (3) designed to penetrate the throat of the victim through the mouth, at least a first one-way valve (4) interposed between said air inlet (2a) and air outlet (3a) to allow the flow of air from said inlet (2a) to said outlet (3a) and prevent the flow of a fluid exhaled by the victim in the opposite direction, the body of said valve (4) including an outlet aperture (4a) for the exit of the fluid exhaled by the victim, and characterized in that the upper end of said insufflated air conveying tube (3) comprises a portion (3b) of tube (3) which is configured for internally receiving the body of said valve (4), the wall of said tube (3) including at least one outer hole (6) communicating with the aperture (4a) of the body of the valve (4) to allow discharging the fluid exhaled by the victim to the outside.

An oral device for temporary placement in a patient's oral cavity includes upper and lower jaw braces and a tongue-engaging member. The upper and lower jaw braces are connected so that the lower jaw brace is advanced in an anterior direction relative to the upper jaw brace when the upper and lower jaw braces are closed together. A partial vacuum is drawn in the oral cavity and the vacuum and lower jaw displacement together control the position of the tongue in order to clear the patient's airway to reduce sleep apnea or treat other conditions.

Methods and devices for delivering a dose, such as a medicament, for inhalation. A dose may be stored by a delivery device and dispersed and delivered in a metered fashion to a subject, such as by the subject inhaling via a mouthpiece of the delivery device. One or more chambers of the device may have a toroidal shape and may be arranged to be selectively opened for fluid communication with a flow path of the delivery device, such as by sliding the chamber relative to a portion of the flow path. The flow path may include a restriction that permits air to bypass the chamber, and/or the chamber may be arranged so that fluid entering the chamber interacts with fluid exiting the chamber so as to enhance dispersion of the dose.

Plural tongue gripping projections coupled to upper and lower supports grip and hold the tongue during sleep and minimize the risk of the tongue slipping back and blocking the throat. One or both of the upper and lower supports are biased together. A tongue depressor extends rearwardly and downwardly from a cross member portion of a jaw coupler. A soft palate engager extends rearwardly from the cross member. The tongue grasping device, tongue depressor and soft palate engager cooperatively resist closing of the user's pharyngeal airway. The tongue depressor and soft palate engager are desirably biased apart and supported by flexible supports to permit movement of the rear of the tongue to close the pharyngeal airway during swallowing.

The present invention relates to a device for delivering a supply of gases to a patient. The device includes a patient interface and connecting member. The connecting member is preferably a L-shaped swiveled connector that is capable of being fixed into one of two positions, a first position where the connector is freely rotatable within the patient interface, and a second position where an interference between the interface and connector prevents the free rotation of the connector within the patient interface, The present invention further relates to a connector that has outlet means, which includes at least one outlet vent and a funnel, which in use directs and passes a substantial portion gases expired from the patient through the outlet vent or vents.

Embodiments presented provide for a medical apparatus that allows for administration of a fluid, such as oxygen, to a patient, and to allow a medical professional to quickly and precisely administer such oxygen and/or a gaseous sedative with little waste.

The present disclosure provides generally for a therapeutic oral device for sleep apnea and associated methods for using the device. According to the present disclosure, the device may comprise a hard palate portion, mouth guard portion, and a tongue retainer portion. The hard palate portion may comprise one or more materials. The hard palate portion may also comprise a composite of materials, including but not limited to embedded materials. The mouth guard portion may comprise one or more components that provide stability and maintain the position of the therapeutic oral device within the mouth. The tongue retainer portion may comprise an airway and a predetermined length. A method of use may comprise the utilization of one or more incremental oral devices to overcome a gag reflex. When the oral device is formed from a mold, the mouth guard portion and the hard palate portion may be custom fit to the dimensions of the intended mouth.

This invention relates to apparatus used to alter the temperature and humidity of gases. The apparatus of the present invention comprises an insufflator, humidifier and transportation means connected to delivery means to deliver humidified and heated gases to a body cavity prior to and during a medical procedure. In one form of the present invention the insufflator and humidifier are contained in the one housing, while in another form the humidifier is located proximal and external to the insufflator. The transportation means that delivers the humidified gases to the body cavity comprises a flexible tubing having located within, throughout or around it heating means. The heating means may be a heat conductive wire, a ribbon of PTC material, or a conducting wire extruded into the walls of tubing, where the tubing may be made from a PTC material or flexible plastics.

A sleep apnea syndrome symptom improvement aid 1 includes a sandwiching target 10 sandwiched by front teeth of a patient, a tongue presser 20 extending from the sandwiching target 10 to the vicinity of the soft palate of the patient and including an elastic body configured to press the tongue, and a detector 30 configured to detect at least one of a vital sign or a salivary component of the patient.

A fluid delivery and airway management device including a tubular member dimensioned for introducing a fluid into a trachea of a mammal, the tubular member having a proximal portion, a distal portion, and a middle portion between the proximal portion and the distal portion. The tubular member is dimensioned for positioning of the proximal portion in an oral cavity of a mammal, the middle portion in an oropharynx of the mammal and the distal portion in an esophagus of the mammal. An inflatable oral cavity balloon is positioned at the proximal portion and dimensioned to occlude the oral cavity. An inflatable esophageal balloon is positioned at the distal portion and dimensioned to occlude the esophagus. Apertures may be formed within the middle portion such that a fluid introduced into the tubular member is output through the apertures to a trachea.
