An endotracheal tube interface apparatus including a enclosed space structure having integrated surrounding walls, a rearward wall and an internal volume, a first hollow stem disposed on the rearward facing wall and a second hollow stem disposed on the sidewall of the enclosed space structure, the first hollow stem accepting an endotracheal tube, the second hollow stem supporting an oxygen delivery tube, both first and second stems open to the internal volume of the enclosed space. The enclosed space structure may slide over the outside surface of the oral end of an endotracheal tube, inserted through the first hollow stem and wherein oxygen is delivered from a machine through an oxygen delivery tube attached over the second hollow stem, the oxygen entering the endotracheal tube after the internal volume of the enclosed space structure is pressurized.

A mouthpiece includes an outer portion comprising a first side, a second side, a first pillar coupled to the first side and configured to rotate about a first axis, a second pillar coupled to the second side and configured to rotate about a second axis, a first upper gum support coupled to the first pillar and configured to rotate about a third axis that is perpendicular to the first axis, a first lower gum support coupled to the first pillar and configured to rotate about a fourth axis that is perpendicular to the first axis, a second upper gum support coupled to the second pillar and configured to rotate about a fifth axis that is perpendicular to the second axis, and a second lower gum support coupled to the second pillar and configured to rotate about a sixth axis that is perpendicular to the second axis.

An endotracheal tube is disclosed that allows a patient to speak while intubated. The endotracheal tube includes a balloon for seating against the trachea and a collapsible portion proximal to the balloon that aligns with the vocal cords. The collapsible portion may be held open by an inner tube which translates within the endotracheal tube. Suction and balloon inflation conduits span the collapsible portion so that suction and balloon inflation may be performed while the patient is speaking. A small distal tube that bypasses the balloon provides some airflow while the patient speaks.

An attachment for a tracheal cannula, the attachment surrounding a cavity, the attachment being open both in a coupling area of the attachment as well as in an orifice area of the attachment, differing in location from the coupling area, for providing an access to the cavity, the attachment having in the coupling area a latching formation, which is designed for the releasable connection to a mating latching formation of the tracheal cannula, the coupling area surrounding a section of the cavity, the section of the cavity surrounded by the coupling area being centrally penetrated by a virtual coupling axis, the coupling axis defining an axial direction along its path, defining a plurality of radial directions orthogonally to its path and defining a circumferential direction running around it, the coupling area having at least one support section, on which the latching formation and a force application area are situated in such a way that by exerting an actuating force on the force application area in the radial direction toward the coupling axis, the support section is displaceable between two positions of different radial distance of the latching formation situated on the support section from the coupling axis; the force application area and the latching formation displaceable by an exertion of force on the force application area of the same support section are situated along the coupling axis at an axial distance from each other.

A stimulation device may include a tube, where the tube defines a lumen therein and a gas outlet. The gas outlet may be configured to allow gas to pass from the lumen to an exterior of the tube. The stimulation device may also include one or more first electrodes associated with the tube, one or more second electrodes, and a nasal cavity interface proximal of the gas outlet and the one or more first electrodes.

A sedation device has a housing divided internally into a ventilator chamber and an associated evaporator chamber which overlap and are separated by a filter mounted between the chambers and forming a common gas-permeable dividing wall between the chambers. An inlet port is provided at one end of the ventilator chamber at a top of the housing for connection to a patient ventilator in use. An outlet port on the evaporator chamber can be connected via a breathing tube to a patient. An evaporator is mounted within the evaporator chamber for delivery of a volatile sedative into the evaporator chamber during use.

An endotracheal safety device comprising an endotracheal tube having a proximal end and a distal end, the endotracheal tube defining a lumen between the proximal end and the distal end, an endotracheal sleeve assembly having a proximal end and a distal end, the endotracheal sleeve assembly defining a lumen between the proximal end and the distal end, the endotracheal sleeve assembly configured to be movable over the endotracheal tube, and an adapter having a proximal end and a distal end, the distal end of the adapter configured to be received by the proximal end of the endotracheal sleeve assembly.

Breathing tubes for use with a spirometer. The breathing tubes include a body having an oval interior cross-sectional shape and are configured to engage interior surfaces of the spirometer, so as to ensure the proper orientation of the body within the spirometer.

One aspect of the invention relates to an intubation aid (10). The intubation aid (10) comprises an elongated main part (12), and the intubation aid (10) is provided with an operating device (26). The main part (12) is designed to be curved in a first region (18) of the main part (12), and the main part (12) is additionally designed to be curved in a second region (20) of the main part (12), said second region being separated from the first region (18) and being arranged adjacently to the free end (16) of the main part (12). The main part (12) additionally comprises a positioning device (24) which is designed to limit a translational displacement of a tube (46) placed on the intubation aid (10) in at least one direction. A second aspect of the invention relates to an intubation aid which can be placed on an endoscope.
