Abstract
A disposable spray nozzle capable of accommodating liquid dose installed in a medical compressor nebulizer or connected to a device of other pressure sources, comprises a dose container and a spray nozzle; the dose container has a guide duct and an unsealing section connected to the guide duct disposed at the opening end of the guide duct. The spray nozzle is disposed on the guide duct of the dose container, and has a dose accommodating space in the dose container; a first opening section and a second opening section are disposed on both ends of the dose accommodating space and sealed respectively by a sealing section, such that the dose as well as the disposable spray nozzle can be inserted directly into the guide duct of the dose container. The unsealing section at the end of the guided duct pierces through the sealing section of the first and second opening sections of the spray nozzle, so that the liquid dose seeps out for the nebulizing operation.
