Abstract: In a press-type medical nebulizer and a pressing means thereof, the nebulizer includes a medicament container having an intake channel and a medical spray generator. The pressing means includes a base, a pressing element and a switching element. The base has a gas-delivering tube, a gas-releasing hole and a trough. The pressing element comprises an operating arm pivotally connected into the trough and a valve for closing the gas-releasing hole. The switching element is slidingly provided on the operating arm to be selectively engaged into the trough for fixing the operating arm. When the switching element is engaged into the trough, the switching element causes the valve to close the gas-releasing hole, so that the pressurized gas can continuously flow through the gas-delivering tube and enter the intake channel. By this arrangement, the user needs not to press the pressing means repeatedly, which is convenient and labor-saving.
