A respiratory obstruction removal device, which includes a face mask and a negative pressure generating device. The negative pressure generating device includes a grip section, an extendable tubular body, and an annular interface, connected in sequence. The extendable tubular body has a variable volume cavity. The face mask includes an upper part that fits with the annular interface, a lower part that corresponds to a face of a patient, and a connecting body that links the upper and lower parts. The respiratory obstruction removal device also includes a first one-way valve located on the annular interface and a second one-way valve for unidirectional expulsion of gas to the outside. The grip portion and the extendable tubular body are detachably connected. This design is efficient and easy to carry and transport, suitable for emergency use in different scenarios.

An applicator apparatus has a delivery tube with differently curved tube sections along the length of the delivery tube so as to be tailored for airway topicalization during video laryngoscopy. The apparatus aims to enhance the precision and effectiveness of airway topicalization, particularly in scenarios where conventional applicators encounter challenges due to the acute angle of the laryngoscope blade. By conforming to the shape of the video laryngoscope, a sigmoidal shape of the delivery tube facilitates precise targeting of glottic structures and the posterior pharynx. This innovation is particularly beneficial for short procedures requiring endotracheal intubation, as proper topicalization is known to reduce coughing and bucking on extubation, mitigating potential surgical complications and minimizing the aerosolization of respiratory particles and viruses.

Various embodiments provide an endotracheal tube having 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. Some embodiments comprise 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. Some embodiments comprise at least one internal projection projecting radially inwardly from an internal wall surface of a distal tip portion of the endotracheal tube, wherein the internal projection comprises a radiopaque portion. Some embodiments comprise an endotracheal tube body which comprises a polymeric material comprising a helically wound, meshed or braided reinforcement structure embedded therein, the helically wound, meshed or braided reinforcement structure being formed from one or more filaments, and wherein one or more properties of the reinforcement structure vary along the length of the endotracheal tube such that the bending flexibility and/or the mechanical strength of the endotracheal tube varies along the length of the endotracheal tube. Some embodiments comprise a pair of longitudinally spaced locally thinned circumferential wall portions provided at a distal end region of the endotracheal tube. Also described are intubation systems including such endotracheal tubes.

An endobronchial tube is provided that includes a medical tube comprising an endotracheal portion and a bronchial portion having a common single lumen extending between a proximal end and a distal end of the tube, a first endotracheal inflatable cuff for sealing against a trachea of a patient, a second endotracheal inflatable cuff positioned distal to the first endotracheal inflatable cuff for sealing against the trachea of the patient; a bronchial inflatable cuff positioned near a distal end of the medical tube after the first endotracheal inflatable cuff and the second endotracheal inflatable cuff, for sealing the left main stem bronchi of the patient, an intraluminal balloon blocker positioned along an inner surface of the bronchial portion for sealing the common single lumen at the distal end of the bronchial portion, and an aperture positioned between the endotracheal portion and the bronchial portion.

A removal-resistant securement device suitable for use with a conventional tracheostomy tube and other devices, and a tracheostomy tube including the securement device are provided. The securement device has a body including an enlarged shield portion, and laterally disposed strap portions. The body is elongated sufficiently to pass over the neck/body part, through the tracheostomy tube/device, and to allow the strap portions to wrap back around the neck and over the shield. End portions of the strap(s) include mechanical or other fasteners for securely mating the ends of the strap portions, preferably at a point overlying a nape of the neck for a tracheostomy device. The shield portion may be larger in size than the straps to reduce pressure on the skin, and to facilitate arrangement of the fastener(s) over the shield portion, so that it can act as a physical barrier between the fastener(s) and the skin.

Provided is a tracheostomy tube structure, which includes a temperature-controllable and deformable wire embedded in the wall of a flexible tube. The wire deforms in response to temperature changes, thereby altering the diameter of the tube. This allows the tracheostomy tube to be inserted with a reduced diameter, enhancing patient comfort during the procedure. After the tracheostomy tube is in place, the tube can expand to a larger diameter as the wire deforms, preventing the accumulation of sputum that could lead to biofilm formation and addressing the issue of sputum accumulation in the space between the tracheostomy tube and the trachea, thereby facilitating better breathing for the patient.

An endotracheal lung suction system includes an endotracheal tube defining a tube lumen, a suction assembly, and an inner suction catheter. The endotracheal tube comprises an inflation connector and an implantation balloon adjacent the distal tube end and fluidically connected to the inflation connection and through which the balloon inflates. The suction assembly comprises a proximal valve and a distal endotracheal tube connector fluidically connected to an interior of the tube lumen. The inner suction catheter passes through and slides within the suction assembly, the endotracheal tube connector, and through the tube lumen to extend slidably out from and back into the distal tube end. The inner suction catheter comprises a distal, inflatable, hollow, inner-suction-catheter securing device and a catheter body defining a main lumen extending through the inner suction catheter and a catheter-securing inflation lumen extending through the inner suction catheter parallel to the main lumen.

An airway management system, comprising: a breathing circuit connector component, an inner tube component, and a connecting tube, further comprising: a laryngeal mask component and a telescopic tube component; or, an endotracheal tube component, the breathing circuit connector component comprises a breathing circuit connector; a plurality of cavities is provided in the laryngeal mask airway tube of the laryngeal mask component; a plurality of cavities is provided in a endotracheal tube of the endotracheal tube component; and one end of the breathing circuit connector is connected to a laryngeal mask connector of the laryngeal mask component, or an endotracheal tube connector of the endotracheal tube component, or the laryngeal mask connector and an inner tube connector of the inner tube component, or the endotracheal tube connector and the inner tube connector, or a telescopic tube machine end connector of the telescopic tube component and the inner tube connector.

A tracheal intubation assistance device and a method for real-time confirming a position correctness of an endotracheal tube are provided. The method for real-time confirming the position correctness of the endotracheal tube includes providing the tracheal intubation assistance device, performing an image capture step, performing a region selection step, and performing an image interpretation step. The tracheal intubation assistance device includes an infrared temperature sensor and a processor. The infrared temperature sensor is configured to capture a thermal image of a workspace including the endotracheal tube and a subject, and the processor is configured to compare a first temperature range of a first sampling region with a second temperature range of a second sampling region to confirm the position correctness of the endotracheal tube.
