A surgical suction device that uses positive pressure gas is shown and described. The surgical suction device includes an air amplifier. The air amplifier includes a structure defining a generally cylindrical cavity having a first opening at a first end and a second opening at a second end. The cylindrical cavity is defined by an inner wall of the cavity. The air amplifier includes an annular opening in the inner wall near the first end. The annular opening defines a jet opening adapted to allow a pressurized gas to flow out of the annular opening such that a low pressure region is produced at the first end and an amplified flow is produced at the second end. The annular opening is further configured such that the pressurized gas enters the cavity at an angle with respect to the inner wall of the cavity that is towards the second end.

Described are gas flow disruption alarms. The alarms can include a gas inlet; a gas outlet configured to couple to a gas delivery device; and a vibration member between the gas inlet and the gas outlet configured to produce an audible sound when a gas delivery device is removed from the gas outlet.

The present invention relates to a respiratory device with a housing comprising a pneumatic unit and at least one further component, in particular a respiratory gas drive, and at least one measuring unit, and also an expiration unit, an accumulator, a control unit and a cooling fan. The pneumatic unit is designed as a pneumatic conveying line which is removable from the housing and which is formed and arranged from an appliance inlet to an appliance outlet of the housing and comprises a support frame on which are arranged at least one component, in particular the respiratory gas drive, at least one sound unit, at least one flow measurement path, at least one measuring unit and the cooling fan.

Illustrative embodiments of new and useful systems and methods for reduced-pressure therapy are described. One example embodiment is a manually-actuated pump for applying reduced-pressure therapy. The pump generally comprises a charging chamber, a regulated chamber, and a regulator passage between the charging chamber and the regulated chamber. A valve body controls fluid communication through the regulator passage, and a regulator spring may be engaged with the valve body to bias the valve body against a differential between a pressure in the regulated chamber and an ambient pressure. The regulator passage may have a bore size adapted deflect the valve body to cause an audible indication of a leak.

A respiratory therapy (RT) system including one or more acoustic generators (8500) to produce an inaudible acoustic signal. The acoustic generator(s), such as when coupled to a patient interface or air circuit of a respiratory therapy device, may provide inaudible acoustic signals indicative of one or more parameters, such as a flow rate or a pressure of the flow of air, or a type of or useable life of a component (e.g. patient interface). The system may have an acoustic receiver that may detect one or more acoustic signals from the acoustic generator, the RT system, the patient or the environment.

An inhaler device (100) for delivering an airborne medicament to a user is disclosed. The device comprises a housing (110) having a chamber (121) for receiving a source of medicament (140), an air flow passage (131) for communicating an air flow through the housing between a passage inlet (132) and a passage outlet (133), and a sensor (135) disposed in the air flow passage which is configured to sense a rate of flow of air along the passage. The device further comprises an orientation sensor (170) for determining an orientation and movement of the inhaler device during use, a processor (160) communicatively coupled with the sensor and orientation sensor for processing data received from the sensor and orientation sensor, and a storage device (162) for storing the data.

An accessory device for delivering medications from attached press-and-breathe metered-dose inhalers (MDIs), including those medications containing hydrofluoroalkane propellants. The device includes a collapsible flexible bag to which is attached a bidirectional mouthpiece and an adaptor that receives the MDI. The mouthpiece contains a reed that functions as an audible signal. The adaptor positions the MDI at an angle to direct the aerosol spray toward the center of the bag. When triggered, the MDI discharges the aerosolized medication into the center of the bag, which medication may then be inhaled by the user through the mouthpiece. The user's inhalation causes the bag to collapse. The reed emits an audible sound if the user inhales above a pre-determined flow rate. A cap seals a gap between the adaptor and an attached canister, making the device in combination with the MDI into a closed-bag system.

Described are gas flow disruption alarms. The alarms can include a gas inlet; a gas outlet configured to couple to a gas delivery device; and a vibration member between the gas inlet and the gas outlet configured to produce an audible sound when a gas delivery device is removed from the gas outlet.

The present invention provides a training device for training a user to use a pressurised metered dose inhaler (PMDI). The device comprises a body, air expulsion means (e.g. bellows) for expelling air along an air flow path and an actuator for actuation of the air expulsion means. The air flow path comprises a restriction such that upon expulsion of air along the air flow path, an audible signal is generated. The audible signal mimics that generated during use of a PMDI.
