  • Publication number: 20160121065
    Abstract: A breathing assistance apparatus comprises a gas supply device, a mask prevent leakage control box (MPLCB), and a mask. The mask is used to cover user's face, and the mask has a gasbag at one side in contact with the user. The gas supply device connects to a gas inlet of the mask through a tunnel, and outputs treatment gas to the user stably. The MPLCB connects to the mask through a windpipe. The MPLCB pressurizes the gasbag automatically when a leakage is detected in the mask, and the gasbag is then inflated to touch the user's face. Therefore, the inside of the mask can remain airtight, so as to prevent the treatment gas in the mask from deflating out of the mask continually.

  • Publication number: 20160067427
    Abstract: A nebulizer includes a nebulizing circuit, a power circuit, a sampling circuit, a filtering circuit and a controlling circuit. The nebulizing circuit includes a piezoelectric actuator. During operation of the piezoelectric actuator, the liquid is nebulized. The power circuit selectively provides electric power to the nebulizing circuit so as to power the nebulizing circuit. A harmonic signal generated by the piezoelectric actuator at a working frequency is sampled by the sampling circuit. A specified frequency of the harmonic signal is retrieved by the filtering circuit. The controlling circuit controls operations of the power circuit and receiving the specified frequency of the harmonic signal. By comparing the specified frequency with a predetermined frequency, the controlling circuit judges whether the liquid is exhausted. Once the liquid is exhausted, the controlling circuit controls the power circuit to stop providing the electric power to the nebulizing circuit.
