38 results about "Positive expiratory pressure" patented technology

Positive Expiratory Pressure (PEP) Positive Expiratory Pressure, or PEP, is a small device that a patient exhales into, using a mask. PEP is also called PEP Therapy, PEP Mask or TheraPEP. The PEP device creates pressure in the lungs and keeps your airways from closing.

Oscillating Positive Expiratory Pressure Device

A respiratory treatment device comprising at least one chamber, a chamber inlet configured to receive exhaled air into the at least one chamber, at least one chamber outlet configured to permit exhaled air to exit the at least one chamber, and an exhalation flow path defined between the chamber inlet and the at least one chamber outlet. A restrictor member positioned in the exhalation flow path is moveable between a closed position, where a flow of exhaled air along the exhalation flow path is restricted, and an open position, where the flow of exhaled air along the exhalation flow path is less restricted. A vane in fluid communication with the exhalation flow path is operatively connected to the restrictor member and is configured to reciprocate between a first position and a second position in response to the flow of exhaled air along the exhalation flow path.

Oscillating positive respiratory pressure device

An oscillating positive respiratory pressure apparatus and a method of performing oscillating positive respiratory pressure therapy. The apparatus includes a housing having an interior chamber, a chamber inlet, a chamber outlet, an exhalation flow path defined between the inlet and the outlet, and a restrictor member rotatably mounted within the interior chamber. The restrictor member has an axis of rotation that is substantially perpendicular to the flow path at the inlet, and includes at least one blocking segment. Rotation of the restrictor member moves the at least one blocking segment between an open position and a closed position. Respiratory pressure at the chamber inlet oscillates between a minimum when the at least one blocking segment is in the open position and a maximum when the at least one blocking segment is in the closed position. By exhaling into the apparatus, oscillating positive expiratory pressure therapy is administered.

Oscillating positive expiratory pressure device

An oscillating positive expiratory pressure apparatus having a housing defining a chamber, a chamber inlet, a chamber outlet, a deformable restrictor member positioned in an exhalation flow path between the chamber inlet and the chamber outlet, and an oscillation member disposed within the chamber. The deformable restrictor member and the oscillation member are moveable between an engaged position, where the oscillation member is in contact with the deformable restrictor member and an disengaged position, where the oscillation member is not in contact with the deformable restrictor member. The deformable restrictor member and the oscillation member move from the engaged position to the disengaged position in response to a first exhalation pressure at the chamber inlet, and move from the disengaged position to an engaged position in response to a second exhalation pressure at the chamber inlet.

Passive respiratory therapy device

A respiratory therapy device including a housing and an interrupter valve assembly. The housing is sized for handling by a patient and defines a patient breathing passage extending from a patient end and through which a patient inhales and exhales air. The interrupter valve assembly is carried by the housing and includes a control port, a valve body, and a drive mechanism. Expiratory airflow is released from the patient breathing passage through the control port. The valve body is sized to at least partially obstruct fluid flow through the control port. The drive mechanism moves the valve body relative to the control port in response to the expiratory airflow such that the valve body repeatedly transitions between a position of maximum obstruction and a position of minimum obstruction relative to the control port to create an oscillatory positive expiratory pressure effect.

Vibratory positive expiratory pressure device

ActiveCN103118730ARespiratorsVibration massageMedicineAirway clearance
A method of providing airway clearance therapy to a patient includes receiving an expiratory airstream from the patient in a chamber, causing a back pressure to be created in the chamber (10) in response to receiving the expiratory airstream, causing a one-way valve, such as a magnetic duckbill valve (26), located downstream of the chamber to open only in response to the back pressure being at least equal to a certain predetermined level, causing a vibratory effect to be generated downstream of the one-way valve, for example using a vibratory ball check valve (32), when the one-way valve is open and in response to the expiratory air-stream passing therethrough, and delivering a percussive sensation to the patient through the chamber responsive to the vibratory effect.

Positive expiratory pressure devices with flutter valve

A positive pressure airway device for providing resistance in an air pathway for a patient exhaling. The device includes a central tube region, a inspiratory air passageway for passing air into the central tube region when a patient breathing through the device inhales, and an expiratory air passageway for passing air out of the central tube region when a patient breathing through the device exhales, A valve in the expiratory air passageway allows air to flow out only when a patient using the device exhales with an expiratory air pressure greater than a selected pressure, and includes a stopper and a coil spring with an interior portion that is free from any structure that would inhibit the “side-to-side” movement of the spring within the housing. The stopper has a cone-shaped air-stopping surface providing a valve angle that is different from, and is preferably slightly less than, the valve-seat angle.

Ventilation nasal plug with positive expiratory pressure

The invention discloses a ventilation nasal plug with positive expiratory pressure. The ventilation nasal plug comprises a casing, wherein two through-holes are formed in the casing; a silicone tube is arranged at each through-hole; a one-way inlet valve is arranged at the bottom of the casing; and a one-way pressure adjustable outlet valve is arranged at the front end of the casing. During the use, the silicone tubes are inserted into nares of a treated patient and then are fixed through a fixing band in a knotting manner behind the head. During inspiration, the one-way inlet valve is opened, and inspiratory resistance is about zero. During expiration, the one-way inlet valve is closed, and air is restrictively expired through the one-way pressure adjustable outlet valve, so that expiratory phase in-airway positive pressure is established, and the pressure range can be adjusted by setting the one-way pressure adjustable outlet valve. The ventilation nasal plug with positive expiratory pressure can be used comfortably; and for a mask claustrophobia patient and other patients who cannot accept mask treatment, sleep is affected less, the nasal plug is easy to carry, and the patient compliance is good.

As for the expiratory positive pressure nasal / face mask with remote monitoring function, the pressure sensor and the temperature sensor respectively detect pressure data and temperature data of the exhaled gas in the gas outlet pipe. When there is no pressure data or the temperature data remains unchanged, the first processor sends a pulse signal to the hypoglossal nerve electrode through a pulse transmitter to stimulate the jaw tongue muscle. The image acquisition device collects the image information of the front of the expiratory positive pressure nasal / face mask in real time and monitors the image information remotely.
