A puncture cricothyrotomy set includes a tracheal tube and a puncture cannula arranged therein, which has a rotary actuating device with a handle. By moving the handle about its rotational axis, the puncture cannula can be moved from its puncture position into the tracheal tube far enough that the tip section is arranged completely within the tracheal tube.

A ventilator apparatus includes a linear electro-mechanical actuator that interfaces with a self-inflating bag including an inlet configured to receive air and an outlet configured to expend the air. A three-way valve is coupled to the outlet via a first flowmeter, an ambient environment via a second flowmeter, and a patient via an endotracheal tube. The first and/or second flowmeters are coupled to pressure transducer(s). A control unit is coupled to the linear electro-mechanical actuator and the first and second flowmeters and includes a control panel, memory including programmed instructions stored thereon, and processor(s) configured to execute the stored programmed instructions to set an inhalation time and an exhalation time. A current inspiratory pressure and a current tidal volume are obtained from the pressure transducer(s) and/or the first flowmeter. A stroke of the linear electro-mechanical actuator is then controlled to facilitate inspiratory and expiratory phases of a respiratory cycle.

A cuff assembly for a tracheostomy tube includes an outer bladder and an inner cuff. The inner cuff is positioned adjacent to the tracheostomy tube, and the outer bladder is positioned adjacent to the inner cuff. The outer bladder is made with a less elastic material and operates at a higher relative pressure. The inner cuff is made with a more elastic or hyper-elastic material and operates at a lower relative pressure. A secondary airflow opening is formed on a lateral wall of the tracheostomy tube between the cuff assembly and a main distal opening of the tracheostomy tube.

A system (10) configured to facilitate humidification of a pressurized flow of breathable gas delivered to a subject (12) comprises a pressure generator (14), a nebulizer (16), a heater (38), one or more hardware processors (22), and/or other components. The pressure generator is configured to generate a pressurized flow of breathable gas for delivery to an airway (24) within a trachea of the subject. The nebulizer is configured to provide fluid droplets (54) to the breathable gas. The heater is configured to heat a volume of the breathable gas before the droplets are supplied to the breathable gas. The breathable gas received by the subject exhibits a target temperature and humidity level at short distance d from the nebulizer due to one or more of a number of the droplets, an average size of the droplets, a gas flow rate, and/or an amount of heating power.

The present invention relates to a tracheal coupling comprising a patient port 33, an outlet port 36, an inlet port 31 between the patient port and the outlet port, such that flow 34 from the inlet port can go to the patient port or direct to the outlet port, and a flow restriction e.g. 32 between the inlet port and the outlet port, or at the outlet port.

A respiratory ventilation apparatus configured to deliver a respiratory gas to a patient interface is provided. The apparatus may include a gas pressurization unit configured to generate a pressurized respiratory gas, a gas inlet port configured to introduce the respiratory gas into the respiratory ventilation apparatus, a gas outlet port configured to discharge the pressurized respiratory gas to a respiration tube, a detection module configured to detect the pressure of the pressurized respiratory gas, at least one non-volatile memory configured to store a plurality of parameters and a plurality of programs, and one or more controllers. The one or more controllers may be configured to initiate the respiratory ventilation apparatus upon a boot operation, and/or initiate a program that constantly reads information from the detection module, and controls the pressure of the pressurized respiratory gas using the information read from the detection module and at least one parameter.

A method of forming a hose includes: extruding a web of plastics material from a first extruder; helically winding the extruded web about a mandrel or at least one rotating rod to form a wall of the hose; feeding an electrical wire into a second extruder; extruding a bead of plastics material around the electrical wire from the second extruder such that the extruded bead includes the electrical wire at a location within a cross-section of the extruded bead; cooling the extruded bead to cool the plastics material adjacent the location to prevent migration of the electrical wire away from the location; re-heating the extruded bead to cause outer surface portions of the plastics material of the extruded bead to become molten; and helically winding the extruded bead onto and about an external surface of the wall to provide the wall a support helix that incorporates the electrical wire.

A surgical instrument for piercing into a human or animal body. The instrument includes an inner portion which is movably arranged within an needle-like outer portion. The outer portion connects to the inner portion through a spring so as to provide with the outer portion during use a load on the inner portion. The outer portion includes a proximal sleeve that provides a finger grip to a person, likely a surgeon. The sleeve is releasably connectable to the outer portion and the instrument includes a release mechanism for releasing the sleeve from the outer portion, which release mechanism is actuable by motion of the inner portion.

A respiratory ventilation apparatus configured to deliver a respiratory gas to a patient interface is provided. The apparatus may include a gas pressurization unit configured to generate a pressurized respiratory gas, a gas inlet port configured to introduce the respiratory gas into the respiratory ventilation apparatus, a gas outlet port configured to discharge the pressurized respiratory gas to a respiration tube, a detection module configured to detect the pressure of the pressurized respiratory gas, at least one non-volatile memory configured to store a plurality of parameters and a plurality of programs, and one or more controllers. The one or more controllers may be configured to initiate the respiratory ventilation apparatus upon a boot operation, and/or initiate a program that constantly reads information from the detection module, and controls the pressure of the pressurized respiratory gas using the information read from the detection module and at least one parameter.

Systems and methods for a tracheal tube inner cannula having an integrated filter are disclosed. In an example, the technology relates to a tracheal tube inner cannula that includes a proximal segment; a distal segment; a tapered segment attached to the proximal segment and the distal segment. The tapered segment includes a tapered lumen; and an integrated helical filter having a proximal filter diameter and a distal filter diameter, wherein the proximal filter diameter is greater than the distal filter diameter, the integrated helical filter having a ramped surface that wraps around a central axis at an angle such that the ramped surface extends distally through the integrated helical filter, the ramped surface including a coating to trap particulates as air flows through the integrated helical filter.
