A bi-directionally articulable endotracheal tube includes an articulator with a lever, pivoted on a bite block that, via two attached diametrical wires threaded through the tube wall, controls an articulee with two asymmetric notches sequestrated by three nested, specialized cuffs. A connector having an oval cross-section can effectively house and stopper a video stylet whose flexible tip is nimbly responsive to the articulator. The endotracheal tube can be partially styletted for routine intubation in a direct or video laryngoscopy, or video styletted as a ubiquitous alternative to intubative fiber optic bronchoscope and in combination with a video laryngoscope for dual imaging intubation.

Provided herein is an endotracheal tube, and an intubation system comprising said endotracheal tube and a stylet for guiding an endotracheal tube during intubation. The endotracheal tube has a body comprising a flexible hollow tube with a distal end for insertion into a patient's trachea during intubation, and an opposite proximal end. The endotracheal tube comprises one or more internal projections, said internal projections projecting radially inwardly from an internal wall surface of a distal tip portion of the endotracheal tube, wherein the internal projections are tapered in at least one direction.

An apparatus for monitoring EMG signals of a patient's laryngeal muscles includes an endotracheal tube having an exterior surface and a first location configured to be positioned at the patient's vocal folds. A first electrode is formed on the exterior surface of the endotracheal tube substantially below the first location to receive EMG signals primarily from below the vocal folds. A second electrode is formed on the exterior surface of the endotracheal tube substantially above the first location to receive EMG signals primarily from above the vocal folds. The first and second electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient.

A breathing gas delivery pipe, a nasal catheter, and a ventilation therapy device. The breathing gas delivery pipe is used for delivering gas to a patient interface, and comprises a gas delivery pipe body (1); and the gas delivery pipe body (1) comprises a gas delivery channel (2) and a heat preservation structure used for preserving heat of the gas delivered in the gas delivery channel (2). In this way, the heat preservation structure preserves the heat of the gas delivery pipe body (1), so that the temperature drop in the gas delivery channel (2) can be effectively slowed down or avoided, thereby temperature drop of the gas delivered in the gas delivery channel (2) is further slowed down or avoided, and the generation of condensed water in the gas delivery channel (2) is avoided.

A ventilation catheter and airway management system is described to create conditions that tend to clear secretions during the normal conduct of ventilation by having an exclusive outflow channel and/or to use a programed cuff leak combined with PEEP to protect the airway. The secretion clearing endotracheal tube may include separate inflow and outflow paths as part of a double lumen, to facilitate breathing when placed in a patient. The double lumen portion intersecting to form a single lumen for protrusion into the intratracheal region allowing the new inspiratory fluid from the airway management system to flow into a patient and the used inspiratory fluid from the patient to flow back to the airway management system. A pharyngeal suction component removes fluid from the intratracheal region via periodic suctioning.

A treatment method includes an indwelling step of indwelling a medical appliance in a trachea T of a patient, the medical appliance having a plurality of types of metals disposed side by side on a side surface of a pipe body, and the medical appliance generates a current between adjacent metals out of the plurality of types of metals when in contact with a foreign substance or saliva having flown into the trachea.

An apparatus for monitoring EMG signals of a patient's laryngeal muscles includes an endotracheal tube having an exterior surface. Conductive electrodes are formed on the endotracheal tube. The conductive electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient. At least wireless sensor is formed on the endotracheal tube, and is configured to wirelessly transmit information to a processing apparatus.

A tracheostomy tube (1) has a shaft (10) with a neck flange (17) dividing the shaft into a patient end (18) and a machine end (19). The shaft is of a silicone material reinforced by a coil (30) embedded within it. The coil (30) comprises multiple closed loops (32) that are longer along the patient end portion than the machine end portion such that the closed ends of the loops contact one another along the machine end portion for maximum strength but leave a longitudinal gap (33) along the patient end portion. An inflation line (14) extends within the wall of the shaft along the gap (33) along the patient end portion (18) and extends externally of the shaft on the machine side of the neck flange (17). The patient end of the inflation line opens into an inflatable sealing cuff (13) extending around the shaft close to the patient end.

A tracheostomy tube has a shaft (10) with a patient end and a connector (14) at its machine end. The shaft is integrally moulded with a boss (15) located between its ends, the boss having two outwardly projecting retaining lugs (20) and two longitudinal alignment ribs (19). A mounting flange (30) is separately moulded of a deformable silicone and has a central collar (31) with two recesses (38) shaped to receive the lugs (20) on the shaft (10), and two alignment slots (36) to receive the ribs (19) on the shaft. The shaft (10) is threaded through the collar of the flange, which is deformed outwardly to enable the lugs (20) enter the collar and locate in the recesses (38). A bonding substance is applied to the shaft or collar to bond the flange on the shaft.

A cuffed tracheal tube has a shaft (10) with an inner component (30) having an inflation lumen (23) extending along a rib (33) along the outside of the component. The rib (33) terminates a short distance rearwardly of the patient end (14) of the inner component. The inflation lumen (23) is closed by an outer layer (51) applied over the inner component (30) and covering the patient end of the rib. Two closely spaced openings (54) through the rib (33) are spaced in the inflatable region of a silicone sealing cuff (13) secured around the patient end of the shaft.
