A CPAP system for supplying humidified gases to a user is disclosed in which various interfaces are described for gas delivery. A mask cushion including a deformable cushion and thin sheath is described.

The endoscope herein described has a unique steering capability allowing the highly flexible distal end of the shaft of the device to be moved to a full range angular positions without rotating the device on its long axis, thus enabling the device to be steered within the cavity of interest. The relative lengths of the control cables used to move the distal end of the bendable shaft can be changed whenever the flexible or malleable shaft is to be re-shaped to a new configuration thus preventing the distal end or the steering mechanism from assuming an undesired angular position. When used as an endotracheal device, a novel tongue retractor is described which forms an internal conduit, allowing passage of the bendable shaft of the endotracheal intubation device and an endotracheal tube therethrough. Methods for performing a tracheal intubation and changing the relative lengths of the cables are disclosed.

Medical devices which are compatible with a camera for ventilating, intubating, and extubating a patient under continuous visualization. Methods for ventilating, intubating and extubating a patient with the medical devices.

A method for use in an endotracheal intubation procedure, the method including: inserting an intubation guide into a mouth of a subject, the intubation guide including an elongate body defining a passageway configured for receiving a blade portion of an intubation device; covering the mouth of the subject with a ventilation mask including: a ventilation port connected to a ventilator, and an intubation port for receiving the blade portion of the intubation device; ventilating the subject using the ventilation mask; and while ventilation of the subject continues: inserting the blade portion of the intubation device into the passageway through the intubation port; positioning a distal tip of the blade portion proximate to the larynx of the subject; and advancing an endotracheal tube along the blade portion of the intubation device through the intubation port and the intubation guide into a trachea of the subject.

A shielded intubation guide for use in an endotracheal intubation procedure, the shielded intubation guide including: an elongate body defining a passageway extending between a proximal opening and a distal opening for receiving a blade portion of an intubation device, the shielded intubation guide being configured for insertion into a mouth of the subject so that the proximal opening is positioned proximate to the mouth and the distal opening is positioned in an airway of the subject; and a shield around the proximal opening for substantially reducing emissions from the mouth, the shielded intubation guide allowing endotracheal intubation to be performed by: inserting the blade portion of the intubation device into the passageway; positioning a distal end of the blade portion proximate to the larynx of the subject; and advancing an endotracheal tube along the blade portion through the passageway into a trachea of the subject.

The invention relates to a mouthpiece for a product dispensing device including a product dispensing duct defining a longitudinal axis and including a connection opening designed to be connected to a dispensing member of the product dispensing device, and a dispensing opening designed to open freely into the mouth of a user, and a lingual cavity designed to receive at least one end of the tongue of the user, including a lingual opening allowing the tongue to be inserted into the lingual cavity and a contact surface designed to form a target for one end of the tongue of the user.

The invention also relates to a product dispensing device and to a method for dispensing a product.

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.

A respiratory interface, such as a mouthpiece, having a vestibular shield overlapping a user's teeth and gums, a gases passageway extending through the vestibular shield allowing for the passage of the gases through mouthpiece and an extra oral seal associated with the gases passageway, wherein the passageway in use causes gases to be diffused when exiting from the gases passageway. Mouthpiece may have an adjustment mechanism to alter distance between the vestibular shield and the extra-oral seal. The interface may include an elbow having a vent.

Systems and methods for measurement of end tidal carbon dioxide, including a device having a body and a tubular gas line. The body is adapted to be attached to a patient airway and has a first gas line securing portion which has an aperture through it and is adapted to secure the gas line to the body. The tubular gas line is secured in the aperture. The tubular gas line has a proximal portion extending from a proximal end of the aperture and has a proximal end which is adapted to be connected to an end tidal CO2 monitor. The tubular gas line also has a distal portion extending from a distal end of the aperture and having a distal end which provides an inlet for end tidal CO2 exhaled by a patient.

Oral airway devices comprising a tubal body formed by a wall which has a length between a distal end and a proximal end, the tubal body being curved into an arch, the wall having two hollow channels which are passages in the tubal body, a first channel and a second channel, wherein the two channels are laterally aligned, wherein the first channel is the passage located peripherally in the tubal body and wherein the second channel is the passage located centrally or substantially centrally in the tubal body and is compatible with a camera insertable and removable from the second channel; and wherein the tubal body does not comprise an endotracheal tube (ETT) lumen.
