Sealed backpressure attachment device for nebulizer |
摘要 |
An attachment for use with a nebulizer for delivery of aerosol medication to respiratory airways of a user has an elongated conduit provided with a one-way valve for admitting ambient air on one of its ends and a mouthpiece-on its opposite end. A calibrated pressure exhalation valve allows escape of exhaled gas once the pressure in the conduit exceeds a pre-determined setting of the valve. The outlet valve is spring-loaded and allows for various calibrations. The conduit is attachable to a nebulizer and facilitates build-up of positive pressure in the user's sealed airways to help maintain the airways distended for more effective delivery of the medication. |
