The invention provides a device for inserting an infraglottic airway or an imaging device into a patient, the device comprising an open channel which is curved along its length, a first end of the device comprising a handle portion and a second end of the device being configured, in use, to extend to the opening of the patient's trachea. The invention also provides an infraglottic airway device comprising an endotracheal tube and two annular inflatable cuffs, wherein each cuff is provided with an inflation line through which the cuffs can be inflated or deflated.

A mechanical insufflation-exsufflation device including an air source to provide positive airway pressure (PAP); a patient interface; at least one sensor to sense air pressure and flow at the patient interface; and a controller to control the air source to deliver at least one mechanically assisted cough to the patient in response to at least one of a target breathing flow and a target inhalation time period being sensed by the at least one sensor, and when the at least one of a target breathing flow and a target inhalation time period is not sensed, the controller is configured to control the air source to deliver each in a series of high-level PAP provided over a duration being followed by a low-level PAP provided over a duration, the series of high-level PAP increasing in pressure level and duration from a prior one in the series of high-level PAP.

A pressure indicator for a respiratory treatment device, the pressure indicator including an instrument for measuring pressures, a conduit configured to transmit a pressure within the respiratory treatment device to the instrument, and a pressure stabilizer orifice positioned within the conduit.

A high flow therapy system for delivering heated and humidified respiratory gas to an airway of a patient, the system including a respiratory gas flow pathway for delivering the respiratory gas to the airway of the patient by way of a non-sealing respiratory interface; wherein flow rate of the pressurized respiratory gas is controlled by a microprocessor.

A positive exhalation pressure device increases the pressure gradient in the airways, thereby increasing oxygen saturation levels and decreasing the severity of hypoxia. Various embodiments of the device may be inserted into the nasal and/or oral cavities, or configured as mask devices covering the nasal and/or oral cavities. In some embodiments, the resistance of the device may be varied.

Techniques for blockage removal is provided, which may provide immediate and effective aid to a choking victim. A blockage removal device may comprise a mouthpiece disposed on an inlet. The inlet may be coupled to a chamber configured to hold a vacuum generated by a vacuum pump. A pressure transducer may send information about the vacuum to an electronic control unit (ECU). The ECU may send the information to a solenoid valve, which may open and close at a predetermined setting, instantly exposing or blocking the vacuum.

An everting vine robot intubation device capable of automatically and autonomously intubating the trachea and producing a lumen through which artificial ventilation may be conducted. The device includes an everting primary vine robot attached to a mouthpiece and a smaller diameter everting intubation vine robot associated with the primary everting vine robot. The primary vine robot is shaped and sized to extend to the back of a patient's laryngopharynx when fully actuated and the intubation everting vine robot is shaped and sized to extend from the primary vine robot into the patient's trachea when fully actuated.

Systems and methods for producing oxygen enriched air using vacuum pressure swing adsorption (VPSA) are disclosed. In one implementation, an oxygen concentrator includes a canister system having at least one canister, a pumping system having at least one motor-controlled pump, a set of valves pneumatically coupling the canister system and the pumping system, and a controller. The canister is configured to receive a gas separation adsorbent. The controller is configured to control operation of the pumping system and the set of valves to: selectively pneumatically couple the motor-controlled pump and the canister so as to pressurize the canister and selectively pneumatically couple the motor-controlled pump and the canister so as to evacuate the canister.

A valve assembly attached to a capacitor such that pressurizing the capacitor to a first positive pressure threshold induces the valve assembly to open, the pressurized air is released to the patient, and then as the pressure in the capacitor drops to a second pressure threshold the valve closes and the capacitor begins to build pressure until the first positive pressure threshold is achieved and the process repeats. Relative to the valve assembly and integrated therein, is an incrementally adjustable index knob to vary the rate of a biasing force performing work against the actionable valve face of the diaphragm functional surface to set the performance of the valve assembly, thereby increasing the potential for correct operation across a range of oscillating rates supporting a broad spectrum of patient therapies and types.

An endotracheal tube fastening apparatus and use thereof for the field of medical apparatuses, specifically to the field of useful apparatuses for fastening devices related to advanced life support to a patient. The present invention discloses an endotracheal tube adhesive fastening apparatus, specifically to endotracheal tubes used for patients' intubation during surgical procedures whenever an artificial respiration system is required. The apparatus of the present invention has a shape that allows complete isolation of the oral cavity during the procedure, as well as ensuring tube stability during its fastening and removal, in order to reduce the possibility of injuries to the patient's airways or hypoxia due to accidental extubation.
