Abstract:
A gas exhaust control method applied to a respiratory assistance apparatus includes the following steps of: applying gas to a face mask of the respiratory assistance apparatus; detecting a pressure in the face mask; when the pressure in the face mask is lower than a preset pressure range, shrinking a perforation size of an exhaust structure of the face mask by a driving unit of the respiratory assistance apparatus; and when the pressure in the face mask is higher than the preset pressure range, expanding the perforation size of the exhaust structure of the face mask by the driving unit. A respiratory assistance apparatus applied with the gas exhaust control method is also disclosed.
Abstract:
A nebulization system comprises a power adapter and a nebulizer. The nebulizer comprises a nebulization module for placing a liquid and a nebulization driving device. The nebulization driving device comprises a battery unit, an input terminal, a voltage detection unit, a voltage adjustment unit, a control unit and a driving unit. The input terminal is coupled to the power adapter and the battery unit. The voltage detection unit detects whether an input voltage of the input terminal is larger than a predefined value. The control unit controls the voltage adjustment unit to adjust the input voltage to a first/second operating voltage as an output voltage respectively if the input voltage is larger/smaller than the predefined value. The first operating voltage is larger than the second operating voltage. The driving unit drives the nebulization module to nebulize the liquid according to the output voltage of the voltage adjustment unit.
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.
Abstract:
Present disclosure relates to a nebulizer and a method for operating the same. The nebulizer includes a nebulizing circuit, a power providing circuit, a selection interface and a control circuit. The nebulizing circuit includes a piezoelectric actuator. The selection interface is configured to select between a first parameter set and a second parameter set, wherein the first and the second parameter sets are set corresponding to a first solution and a second solution respectively. When the first parameter set is selected, the control circuit controls the power providing circuit to drive the nebulizing circuit with a first voltage, and the first solution is nebulized in a first particle size. When the second parameter set is selected, the control circuit controls the power providing circuit to drive the nebulizing circuit with a second voltage, and the second solution is nebulized in a second particle size.
Abstract:
