A manual inexsufflator including a standard mechanical ventilator, a medical suction unit, and a piston-like sliding valve mechanism which connects a patient ventilation interface with either the ventilator or the suction unit. By sliding the valve mechanism in and out the user selectively connects the patient to either the ventilator, for purposes of insufflation, or the suction unit, for purposes of exsufflation. The ventilator may generate expiratory positive airway pressure between inexsufflation cycles.

An improved insufflation-exsufflation system with percussive assist for removal of broncho-pulmonary secretions includes a conduit for connection to a patient's airway; a pressure source for providing to the conduit alternating positive and negative pressure fluctuations at a first rate corresponding to patient insufflation-exsufflation; and a control mechanism for varying pressure during positive and negative pressure fluctuations at a second higher rate to periodically decrease the positive pressure during positive fluctuations and decrease the negative pressure during negative fluctuations to provide percussive pulses during at least one of insufflation-exsufflation to clear broncho-pulmonary secretions from the patient's airway.

An MIE apparatus has a blower, a direction valve, an oscillator, and a mask hose connector. The blower is connected to the direction valve, which is connected to the oscillator, which is connected to the hose connector. During insufflation, a direction valve connects exhaust of a blower to an oscillator, causing positive pressure at the hose connector. During exsufflation, the direction valve connects the blower intake to the oscillator, causing negative pressure at the hose connector. The oscillator is a butterfly valve with a 360° rotating disc. During insufflation, the disc is fixed to steadily modulate the airflow. During exsufflation, the oscillator is inactive or in flutter mode. When inactive, the disc is fixed to allow maximum air flow. In flutter mode, the disc continuously rotates so that the air flow rapidly alternates between maximum and minimum.

A method of assisting a patient with airway clearance includes providing a positive pressure insufflation gas flow to the patient during an insufflation phase, following completion of the insufflation phase, causing the patient to enter an expiratory hold condition wherein the patient is prevented from exhaling, providing an abdominal thrust to the patient while the patient is in the expiratory hold condition, terminating the expiratory hold condition, and following termination of the expiratory hold condition, providing a negative pressure exsufflation gas flow to the patient during an exsufflation phase.

The invention provides a nasal mask device. The nasal mask device comprises nostril pipes, breathing cavities and an exhaust portion and involves a filter wearing method. The breathing cavities are communicated with the nostril pipes respectively. A one-way air inlet valve is arranged at the air inlet of each breathing cavity. A one-way exhaust valve is arranged at the air outlet of the exhaust portion. The nasal mask device further comprises nostril rubber sleeves and an adjustment portion arranged between the two breathing cavities. The nostril rubber sleeves are arranged at the ends of the nostril pipes. The adjustment portion is inserted into the breathing cavities in a penetrating mode and connected with the breathing cavities in an airtight mode through soft sealing rings. The nasal mask device is attractive in appearance and not prone to falling when worn, the nose distance can be freely adjusted according to the sizes of noses of people, and people can be prevented from injuries caused when people fall and the nostril pipes go deep into nostrils.

The invention relates to a breathing machine positive end-expiratory pressure control system, circuit and a control method thereof. The control method comprises a PEEP (Positive End Expiratory Pressure) execution part and an electronic PEEP control part, wherein the PEEP execution part is connected with an electronic PEEP part patient respiration pipeline; the electronic PEEP control part is connected with a respiration valve PEEP control port; the drift diameter of the control port can be controlled by regulating the current of a proportional solenoid; a venting air-resistor of which the rear end has the fixed drift diameter is matched with the drift diameter of the proportional solenoid; and the rear end of the body of the proportional solenoid achieves different PEEP pressure set values. The control method comprises the following steps: obtaining the current PEEP pressure; judging whether the PEED pressure is normal; if yes, clearing a regulation record; judging whether PEED pressure is regulated; regulating the current of the proportional solenoid, and returning; judging whether current PEEP pressure is too much or too little; switching on a two-digit three-way solenoid valve, and returning; judging whether the regulation record exists if the current PEEP pressure is too much; if no, regulating the current of the proportional solenoid, and returning; and switching off the two-digit three-way solenoid valve.
