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.

A flow generator for generating a mixed oxygen air flow, the flow generator including a body having a first inlet, a second inlet, an outlet, and one or more inner surfaces that define a first inner chamber in fluid communication with the first inlet and the second inlet, a second inner chamber in fluid communication with the first inner chamber, and a third inner chamber in fluid communication with the second chamber and the outlet of the body. The flow generator includes a connector disposed in the first inlet and a nozzle disposed within at least a portion of the connector and extending into the first inner chamber. The flow generator further includes an adapter engaged to the nozzle to form a fluid tight path such that the adapter connects to an external oxygen source and transports oxygen into the nozzle.

The invention refers to a head and/or neck-mounted respiratory protection device (10) comprising a body-wearable elongated mount (12) for attaching the respiratory protection device (10) to the head and/or neck of a user, a reservoir (14) for storing a bioactive substance (30), and an aerosol generating device (16) connected to the reservoir (14) to receive the bioactive substance (30). The aerosol generating device (16) is configured for generating an aerosol comprising the bioactive substance (30) and for dispensing said aerosol into a respiration area in front of the mouth and nose of the user in order to provide a sterilising atmosphere therein. The invention further refers to a corresponding method of controlling a respiratory protection device.

Respiration aiding equipment is provided, wherein the respiration aiding equipment includes a main control module, a heating loop and a heating loop protective circuit connected to the heating loop, and the heating loop protective circuit includes an acquisition sub-circuit, a suppression sub-circuit, a protective sub-circuit and a discharge sub-circuit; the acquisition sub-circuit collects input voltage of the protective sub-circuit and sends the input voltage to the suppression sub-circuit; the suppression sub-circuit clamps the input voltage and releases current through the discharge sub-circuit; and the protective sub-circuit performs short-circuit protection when the current is too high. In the present disclosure, the over-voltage protection is realized through the voltage clamp in such a manner of monitoring the voltage of the heating loop and suppressing the input voltage through the suppression sub-circuit, and then the over-current protection is realized through the protective sub-circuit when the circuit current is too high.

A nasal cannula interface is provided for a respiratory support system configured to receive a breathable gases flow, the nasal cannula interface comprising: a. an inlet to receive the gases flow; b. at least one nasal prong configured to receive the gases flow from the inlet, and to be received in, and to deliver the gases flow to, a nare of the patient. The nasal cannula interface may comprise one or more structural features that are configured to help manage, avoid and/or reduce generation of aerosols by the patient during breathing and/or whilst breathing gases from a respiratory support apparatus.

Provided is a filtering facepiece respirator. The respirator includes a mask body having an anterior side portion, a posterior side portion, a middle portion, a first side portion, a second side portion, a top side portion, a bottom side portion and outer edge portions. The respirator further includes a primary port positioned at the anterior middle portion of the mask body and a detachable primary port adapter which is positioned over and engages the primary port. The respirator may further include an oxygen port and oxygen port adapter and a luer port and luer port adapter.

A medical drape which is positioned over the head and upper torso of a patient is disclosed which includes a head flap, a head portion, a torso portion, and two oppositely disposed arm portions. The head flap is of a sufficient length to extend about the backside of the patient's head. The head portion includes oppositely disposed side wings which aid in covering the head of a patient. Each arm portion includes an access slot extending through the arm portion.

An apparatus for delivering a flow of gas having: a controller; a housing defining a gas-flow passage flowing a high concentration oxygen gas; a motor with windings, resilient bearing mounts and an impeller to deliver the gas through the gas-flow passage; a flexible printed circuit electrically connecting the motor to the controller and sensor system; and an elastomeric shield to pneumatically isolate the windings from the gas-flow passage.
