The invention relates to a respiratory therapy device (1) for treating the musculature of respiratory tracts, lung functions and/or mucous deposits in the lungs, nose and/or throat of a patient (2), consisting of a hollow body (3) in which at least one through-channel (4, 5) is provided, a mouthpiece or nosepiece (6) which is inserted into the hollow body (3) and which is connected to the patient (2) during the duration of the treatment by the respiratory therapy device (1), and consisting of at least one vibration body (11, 12) which is arranged in the interior of the hollow body (3) and which is caused to vibrate in an oscillating manner by the inhalation and/ or exhalation of the patient (2), wherein an oscillating, resistive and/or threshold-typical air pressure vibration occurs, the individual resistances during the inhalation and exhalation being adjustable specific to the patient and a modification or repositioning of the respiratory therapy device (1) not being required. This is solved in that a retaining body (13) is inserted into the hollow body (3), into which retaining body at least one opening (14) is integrated, in that a freely oscillating tongue (15) is fixed to the hollow body (13) in the region of the opening (14), by means of which tongue the opening (14) of the retaining body (13) is closed or opened in regions according to the air flows (7, 8) prevailing in the interior of the hollow body (3), in that the end face (9) of the hollow body (3) opposite the mouthpiece (6) is open, in that a stenosis (18) is inserted into said end face (9), into the shell surface (19) of which stenosis at least two passage openings (20) are provided through which the air flows (7, 8) flow into the interior of the hollow body (3) or vice versa, in that the passage openings (20) of the stenosis (18) have different cross-sectional areas than air passages for the air flows (7, 8) and that the stenosis (18) is rotatably mounted in the hollow body (3), such that one of the passage openings (20) can be selected or adjusted as an air passage by rotating the stenosis (18).

The present invention refers to a respiratory assistance device that provides respiratory support to patients when they are unable to do it on their own or have difficulties in doing so, where it is made up of a series of electronic, mechanical and control arrangements to execute such actions, providing a constant flow of air/oxygen to the patient.

A ventilator is provided that dynamical adjusts the pressure, flow, and volume of the delivered gas to a patient as the condition of the patient changes. The ventilator adjusts the flow and mixing of gases through flow control valves. The ventilator includes at least two banks of valves, each bank having a plurality of valves, where each valve in the bank has a specific orifice size that is different from at least one other valve in the respective bank of valves. In one example, the ventilator further includes an exhalation valve assembly having an exhalation valve housing and exhalation valve base coupled together to retain a flexible exhalation tube. The exhalation valve assembly including at least two pistons extending at least partially through the exhalation valve assembly to contact the exhalation tube and, when actuated, impart pressure on the walls of flexible exhalation tube to restrict or completely close the flow of air through the flexible exhalation tube.

Disclosed is a fluid trap for use with, or comprising part of, a respiratory therapy system, and in particular comprising part of, or configured to be connected to, a breathing limb, such as an expiratory limb, of a respiratory therapy system. The fluid trap comprises a container configured to contain fluid received from an inlet; a closure, the closure and container being configured to be removeably mounted together to close the container; and a valve configured to be removeably mounted on at least one of the container and the closure, and configured to be in a closed condition which prevents fluid from flowing through the inlet when the closure is not mounted on the container, the valve being further configured to be in an open position which allows fluid from the inlet into the container when the closure is mounted on the container.

The invention relates to a protective cover (1) for a medical ventilator (20) adapted for use in a contaminated environment, in particular an NRBC environment, having a peripheral casing (2) defining an internal compartment (3) designed to accommodate a medical ventilator (20). The peripheral casing (2) has a plurality of connection interfaces (4, 5, 6, 7) sealably attached to said peripheral casing (2). Each connection interface (4, 5, 6, 7) has at least one internal gas passage with at least one gas inlet and at least one gas outlet. A sealing device is arranged in the internal gas passage of at least one connection interface (4, 5, 6, 7) for sealing said internal gas passage.

Systems and methods for novel ventilation that allows the ventilator to detect a patient intention to cycle exhalation are provided. Further, systems and methods for cycling exhalation based on a muscle pressure are provided.

A method includes emitting an acoustic signal into an airway of a user. The method further includes, detecting an acoustic reflection of the acoustic signal caused by one or more physical features within the airway of the user. The method also includes analyzing acoustic data associated with the acoustic reflection. The method also further includes characterizing an occurrence of the physical obstruction in the airway of the user. The characterization is based, at least in part, on the analyzed acoustic data. The characterization is indicative of an apnea event or a hypopnea event in the user, wherein the apnea event comprises an obstructive apnea event, a central apnea event or a mixed apnea event, and further distinguishes between the occurrence of the obstructive apnea event, the central apnea event, the mixed apnea event or the hypopnea event in the user.

A method includes receiving first data associated with a first sleep session of a user. The method also includes determining a first set of sleep-related parameters associated with the first sleep session of the user based at least in part on the first data. The method also includes receiving second data associated with a second sleep session of the user. The method also includes determining a second set of sleep-related parameters associated with the second sleep session of the user based at least in part on the second data. The method also includes receiving third data associated with a variable condition. The method also includes causing one or more indications associated with the variable condition and the first sleep session, the second sleep session, or both to be communicated to the user.

A medical breathing gas delivery system design employs a manifold delivering gas in a controlled fashion to patients which includes two inhaled gas one-way valves, at least one pressure sensor for patient airway pressure monitoring, and one controlled exhalation pressure proportional control valve which may be overridden by patient exhaled pressure or if there is a power loss. The manifold is connected to a controlled source of breathing gas which may, for example, be a variable-speed fan, or a pressure-based gas flow controller with dynamic self-calibration employing a fast-acting valve and a pressure sensor, either of which yield predictable gas flow control with a minimum of components. The manifold exhalation pressure control valve and gas flow source may, for example, be controlled with a computer system which adjusts the valve power waveforms to attain the time-varying flow and pressure curves required by clinicians, then stores and displays the waveforms to enable long-term trend monitoring and alarm generation. Accurate gas mixing using the pressure-based gas flow control yields automatically calibrated mixes which are of use for patients in, for example, intensive care ventilation and in anesthesia machines for operating rooms.

A passive valve for use as a fixed leak valve. The valve includes a body having an internal chamber, first and second body ports in fluid communication with the chamber with the first port configured for fluid communication with a patient connection and the second body port configured for fluid communication with a ventilator, a body passageway in fluid communication with the chamber and with ambient air exterior of the body, and a check valve seal positioned to seal the body passageway to permit the flow of gas within the chamber through the body passageway to the exterior of the body and to prevent the flow of ambient air exterior of the body through the body passageway into the chamber. In alternative embodiments, the valve is incorporated into the patient connection or constructed as a separate part connectable to the patient connection.
