The present invention provides an improved visual laryngeal mask comprising a snorkel, an end of the snorkel is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. The inner wall of the snorkel longitudinally extends an imaging cavity and a cleaning channel. The imaging cavity has a built-in imaging device, and the imaging cavity and the cleaning channel protrude forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device.

Systems, devices, and techniques are described to position a tube in a trachea of a patient as part of an intubation procedure. An intubation system may include a stylet configured to position a tube in the trachea of the patient. The stylet may include an articulating segment and a support segment. The articulating segment may be configured to move between a first position and a second position in response to input received by the support segment. The movement of the articulating segment may be controllable by a caregiver. The intubation system may include a handle configured to receive an input from the caregiver and cause the stylet to move in response to the input.

A medical appliance for the treatment of one or more sleep disorders such as obstructive sleep apnea in a patient, the appliance comprising: a biasing member for inserting behind and exerting a force upon the patient's soft palate or tongue, wherein the biasing member is inserted in a reduced or minimized form and then expanded or firms once in place to exert the force. The appliance may be nasally inserted or be placed through the mouth. In a particular configuration, both the soft palate and tongue are biased to prevent obstruction of the flow of air in the nasopharyngeal airway.

Disclosed is a laryngoscope insertion section having a curved superior surface, a curved inferior surface, and a channel extending from the proximal end the channel having an inferior surface with a greater curvature than the curvature of the inferior surface. The insertion section is compatible with laryngoscope hardware optimized for indirect viewing, yet enables direct viewing. The distance between the inferior and superior surfaces is at a maximum within the intermediate portion, and enables the dimensions of the proximal and distal portions to be minimized. Thus, the intermediate portion, located in the patient's oral cavity in use, is provided with greatest depth and strength where the greatest forces are received, whereas the distal and proximal portions are of reduced dimensions to minimize trauma to the patient's airway and mouth areas, respectively. Structural features providing the insertion section with improved strength, with a minimum of material and size, are also disclosed.

An intubation apparatus includes an inserting section that has an elongated shape and is to be inserted from a mouth of a subject toward a target site. An intubation tube is formed to extend along a longitudinal direction of the inserting section and is advanceable and retractable with respect to the inserting section. An imaging section is placed at a tip end of the inserting section and takes an in vivo image of the body of the subject. A detecting section detects a target site from the in vivo image based on a feature amount of the target site that is preset. A notifying section is disposed integrally with or separately from the intubation apparatus and notifies an operator who operates the inserting section. A notification controller controls the notifying section to notify of information relating to the target site of the subject based on a result of the detection.

There is provided an endoscope for use in intubation. The endoscope comprises a housing, a display device having a display screen, and an operative member extending from the housing, the operative member being configured to be inserted into a patients airway and to transmit images to the display screen. The housing comprises an actuator coupled to the operative member and a retainer coupled to the display screen, the housing having a handle portion comprising at least the actuator, and the actuator being single-handedly rotatable by a user relative to the retainer, such that the operative member is rotatable relative to the display screen.
