Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus.

The present invention provides laryngeal mask airway for sedative endoscopy, including: a laryngeal mask/endoscope guide unit which is positioned in a larynx region inlet through a patient's oral cavity and guides a supply of air to a respiratory tract and insertion of an endoscope into an esophagus; an airway unit which is connected to the laryngeal mask/endoscope guide unit to supply air to the patient's respiratory tract and to allow the patient's breathing state to be visually checked; a mouthpiece unit which is installed outside the airway unit and fixed between the patient's teeth to protect a tube of the airway and an endoscopic probe inserted into the oral cavity; and an indication end which is positioned at a portion of the mouthpiece positioned outside the oral cavity and moves in accordance with the patient's breathing state to allow spontaneous breathing to be checked, such that the patient's safe airway may be ensured, the insertion of the endoscopic probe and the procedure may be smoothly performed, the patient's spontaneous breathing is easily checked even in a dark space, and as a result, the endoscopy may be safely performed.

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.

A breathing apparatus includes a mouthguard that fits on a user’s upper teeth, a breathing channel with an airway protruding from a central portion of the mouthguard, and a motor housed within the breathing apparatus operated by a circuit board.

Provided is an endoscope holder capable of turning or swinging an endoscope inserted into a body with the endoscope fixed at a predetermined insertion position. An endoscope holder (1) includes a holder main body (3) having an insertion hole (2), gripping members (7a) and (7b) configured to pinch an endoscope E inserted into the insertion hole (2), first elastic members (12a) and (12b) configured to urge in a direction in which the gripping members (7a) and (7b) are separated from each other, a pressing member (13) configure to press the gripping member (7a) toward the gripping member (7b), a switching mechanism (17) configured to hold or release a pressing state, rollers (10) provided in gripping members (7a) and (7b), and a second elastic member (15) configured to swingably support the gripping member (7b).

A bite block includes a main body and a mouthpiece extending outward from the main body and configured to be positioned in a mouth of the subject when the bite block is in use. The mouthpiece can include a main channel configured to receive an endoscopic tube and a sampling channel configured to receive orally exhaled gases from the subject. The bite block can include a gas delivery channel configured to direct gases into the subject's mouth, the gas delivery channel extending through a portion of the main body and through a portion of the main channel such that the gas delivery channel is in fluid communication with the main channel. The bite block can include a recess extending along a portion of the first surface of the main body proximate the gas delivery channel and configured to receive a portion of a gas delivery tube.

A lower jaw thrusting (LJT) mandibular protracting oral airway device including an elongate member with a distal end and a proximal end defining an air passageway channel. The elongate member includes a lip flange, a curved main body, and a bite block. The lip flange is located at the proximal end and has an outwardly projecting surface. The curved main body extends to the distal end. The bite block is disposed between the lip flange and the curved main body. The bite block includes an upper dorsal surface having a first bite portion for maxillary incisor teeth engagement and a lower ventral surface having a second bite portion for mandibular incisor teeth engagement. The bite block includes a mandibular flange projecting downwards from the lower ventral surface located distal to the second bite portion for mandibular incisor teeth engagement and proximal to the first bite portion for maxillary incisor engagement.

A micro, single piece, tubeless, cordless, directly inserted oral, nasal or hybrid sleep apnea treatment/anti-snoring device having controlled positive air-flow using a vibrationally isolated micro-blower to maintain an individual's upper airway unobstructed (pharynx area) with or without lower jaw, mandibular advancement is disclosed.

In endotracheal tube positioning device for providing fixed positioning and slidable repositioning of a patient's endotracheal tube within a patient's oral cavity includes a neckband, slide track member, a bracket for securement of the tube, and a flexible overlay strip. The slide track member, bracket, and overlay strip are affixed to the neckband. The device permits slidable side-to-side adjustment of the secured endotracheal tube within the patient's oral cavity without having to remove or detach the neckband from around the patient's neck. The bracket can be secured to the endotracheal tube by with an adhesive backed tape or a tube securement strap having engagement elements mating with an adhesive backed patch adhered to the endotracheal tube.
