A reservoir configured to retain a volume of liquid for use in an apparatus for humidifying a flow of pressurised air comprises a base portion and a lid portion. The reservoir may be configured to improve its level of thermal contact to the heater plate using the flow of pressurised air. The reservoir may be configured to improve thermal contact between the reservoir and the heater plate by pre-compression upon engagement of the reservoir with the humidifier. The reservoir may comprise a removable intermediate portion, which may include the inlet tube and/or the outlet tube, for improved access for cleaning. The reservoir may also be configured to prevent overfilling. Overfill prevention features in the reservoir may include defined flow egress paths and/or formation of air locks.

The present invention relates to a turbine ventilator having a fast response to the required inhalation of a subject connected to the ventilator. The turbine ventilator (1000) comprises: a first valve (3) connectable to at least one breathing orifice of the subject; an inspiratory reservoir (6) having an adjustable volume, said inspiratory reservoir being fluidically connectable to said first valve; a turbine unit (1) fluidically connectable to the inspiratory reservoir, said turbine unit being fluidically connectable via said first valve to the at least one breathing orifice of the subject; and a control unit (9) configured to control said first valve for controlling a flow or pressure from the inspiratory reservoir and/or turbine unit to the subject based on setpoints.

A system for pressurizing liquid is described herein. The system may include a liquid reservoir and a pump coupled to the liquid reservoir, the pump to draw liquid from the liquid reservoir. A compliant volume coupled to the pump receives liquid from pump. The compliant volume is composed of an elastic material to increase pressure of the liquid. A valve coupled to the compliant volume receives pressurized liquid from the compliant volume.

A gas supply apparatus with improved control is provided. The gas supply apparatus provides gas at an outlet junction. The apparatus includes a gas mixer for gasses from primary and secondary supplies to a given ratio. The apparatus also includes a gas reservoir supplied by the gas mixer. A tertiary supply valve is also included and connected in parallel with the reservoir. The tertiary supply valve is adapted to connect the outlet junction to a tertiary gas supply when gas is not being supplied to a mixer by the primary and/or secondary supply.

A device and method for adjusting a tidal breath delivered to a patient. The device includes a moving frame which is configured to move over a stationary frame that is nested within the moving frame itself. Disposed between the moving frame and the stationary frame is a compressible bellows which delivers a tidal breath to the patient each time the moving frame is passed over the stationary frame. The specific volume of the tidal breath that is delivered may adjusted according to the estimated weight of the patient, thereby preventing over inflation of the patient's lungs while undergoing treatment. To adjust the tidal breath volume, the user quickly changes the relative position of a slide adjuster which dictates the range of possible movement between the moving frame and the stationary frame, thereby limiting the volume of air/oxygen which may be drawn into the bellows.

A catheter connector assembly which may be included with a corporeal drainage system, and a method of draining fluid from a bodily cavity. The catheter connector assembly may include a catheter connector and a drainage line connector. The catheter connector may include a connector body with a coupling feature, a deformable sealing element, and a retaining member. The drainage line connector may include a drainage line body first and second hinge clips, and an actuator. The actuator is designed to deform the deformable sealing element when the drainage line connector is coupled to the catheter connector.

A water reservoir includes a reservoir base configured to hold a predetermined maximum volume of water to be used for humidification of pressurized breathable air, a reservoir lid pivotally connected to the reservoir base to allow the water reservoir to be movable between an open position and a closed position, the reservoir lid comprising an inlet and an outlet, and a seal configured to sealingly engage the reservoir lid and the reservoir base when the water reservoir is in the closed position, wherein the reservoir base includes an overfill protection element having an egress path for water at a predetermined location.
