An airway device to be inserted into a patient's throat and to be function as a supraglottic airway device during a positive pressure ventilation and spontaneous ventilation that includes an air tube, an air sac, a tongue lifting means, a pulling unit and a drainage systems. The pulling unit will be pulled by an operator's hand to cause the tongue lifting means upward movement to open up the air sac and lift up the tongue base. The air tube lumen and the air sac are configured to have inflow airflow be divided and follow specific route therefore to deliver the focused airflow to vocal cords opening, and also to let inspired airflow enter desired area of the air sac to expand the air sac to form seals with surrounding tissue. During expiration, the pressure will be relieved. Different design of the drainage system can be configured to drained fluid from upper esophagus or from posterior pharyngeal wall.

An airway management device (10) for a human or animal subject (20) includes an airway tube (101) having a first end for disposal external to the subject (20) and a second end (102) for disposal in a portion of an airway of the subject (20). A light emitting element (108) and a photo-sensing element (109) may be disposed at the second end (102) of the airway tube (101). The light emitting element (108) may be configured to transmit light to tissue adjacent to the light emitting element (108). The photo-sensing element (109) may be configured to receive reflectance spectra (204) from the tissue. The location of the second end (102) of the airway tube (101) may be determined from characteristics of the reflectance spectra (204) of the tissue.

Systems, methods, and devices are disclosed for accurately detecting a position of an endotracheal tube by sensing patient anatomy surrounding the endotracheal tube. Systems of the present disclosure include an endotracheal tube having at least one sensor supported by the endotracheal tube configured to detect surrounding patient anatomy. A signal processing unit can receive data from the sensor and can at least one of (i) identify the detected patient anatomy, for example, vocal cords, (ii) determine a distance between the detected patient anatomy and a known point on the endotracheal tube, and (iii) verify a positioning of the endotracheal tube within a tracheal or esophageal lumen of the patient. In some embodiments, the system can include at least one inflatable component that can extend along an outer surface of the endotracheal tube and support the at least one sensor.

A tracheal tube inserted through the trachea and bronchi of a subject, comprising: a tube body having a through hole on an outer circumferential surface thereof, a bronchial cuff provided on an outer circumferential surface of the tube body and pressing an inner circumferential surface of the bronchus; wherein the bronchial cuff is spaced apart in the axial direction of the tube body and forms a plurality of ventilation spaces; wherein the ventilation spaces are in communication with each other; wherein the through hole communicate with the ventilation space.

An endotracheal tube apparatus with improved deployment and long-term comfort to a patient generally includes a cap mechanism that can direct enriched oxygen towards the patient's lungs while the endotracheal tube apparatus is being inserted in a patient's trachea. Once the endotracheal tube is fully inserted in the trachea, the cap mechanism can be made to redirect the enriched oxygen to inflate an inflatable cuff integrated with the endotracheal tube thereby blocking off the vocal cord region in the patient and stabilizing the endotracheal tube in the trachea. When the cuff is inflated, the cap mechanism can be made to ventilate the patient.

This invention is a device to be used with a system for supplying anaesthetic or respiratory gases into the airway of a human or an animal. This device is a face mask, which includes a main body or shell which is lined with one or more air filled cuffs of which at least one cuff is closely reflecting the airway pressures generated inside the shell during the various phases of the respiratory cycle and is inflated by the gases supplied directly from the anaesthesia or ventilator circuit through a specialised adaptor and a dedicated inflation port. Many other advantages of the invention will be apparent from reading the description which follows in conjunction with the accompanying drawings

Example neurostimulation induced medicine devices and methods of use are described herein. An example endotracheal device can include an elongate tubular member having a proximal end and a distal end, an inflatable cuff arranged between the proximal and distal ends of the elongate tubular member, and an electrode array disposed in proximity to an exterior surface of the inflatable cuff. The inflatable cuff can be configured to expand to contact a subject's tracheal wall. Additionally, the electrode array can include a plurality of flexible electrodes, where a set of the flexible electrodes anatomically align with a region of the subject's tracheal wall for selectively targeting vagus nerve activity.

A medical device for the treatment of one or more sleep apnea disorders such as obstructive sleep apnea in a patient is provided. The device includes a scaffolding element positioned about a distal portion of an elongate shaft. The scaffolding element receives a volume of fluid to expand the scaffolding element to exert a force upon a soft palate and/or base of a tongue of a patient. The scaffolding element provides a helical breathing pathway when inserted into an airway of the patient and transitioned to an expanded state.

A stylet is disclosed for insertion into an endotracheal tube for guiding the tube during intubation. The stylet has a body (3) with a pivotable tip portion (5) at its distal end which is movable in either of two opposing directions away from the axis of the stylet. The tip portion (5) may carry an image acquisition device for video imaging. A control mechanism for controlling the pivot angle of the pivotable tip has a hand-operated actuator (7) at the proximal end of the stylet and flexible control wires (23) extending down the stylet to connect the actuator to the pivotable tip portion (5). Also disclosed is an endotracheal tube (100) usable with the stylet and having a bending portion (103), defined by a concertina or thinned portion, at its distal end to facilitate bending of its tip portion (104) by the stylet tip portion (5).

The invention relates to a medical device (1) for trachea pressure measurement comprising a tracheal tube defining an inner surface (12a) and an outer surface (12b) and having a proximal end (1a) and a distal end (1b), configured to be inserted at least partially into the trachea of a subject or animal to deliver respiratory gases to the subject.

The medical device comprises at least one capacitive pressure sensor (20) arranged at said distal end (1b).
