Signal coupling for humidifier container |
摘要 |
A hermetically sealed unitary liquid container of a thermoplastic material suitable for use in inhalation therapy is disclosed as having a signal coupling. A cupshaped female connector is adapted to be threaded onto a gas inlet coupling of the container. A stem portion of the female connector defines a signal gas passageway and a flat land. A flexible elastic sleeve occludes the signal gas passageway and lies continuous with the land. When a pressure buildup is experienced within the container, gas pressure will force gas out through the signed gas passageway, and past the sleeve, while generating an audible signal, e.g., a whistling sound.
