Abstract
A nebulizer comprises a housing, a closed pressure system, at least one pressure relief mechanism and a nebulization mechanism. The housing comprises a nozzle, and the nozzle comprises an outlet portion and an inlet portion communicated with a pressurized gas source. The closed pressure system comprises at least one gas inlet and a gas outlet. The at least one pressure relief mechanism is disposed on the at least one gas inlet. The nebulization mechanism is capable of moving to a nebulization position. An interior pressure in the closed pressure system is changed by the at least one pressure relief mechanism to control the nebulization mechanism for nebulization.
Claims22
A nebulizer, comprising:
- a housing comprising a nozzle, the nozzle comprising an outlet portion and an inlet portion communicated with a pressurized gas source;
- a closed pressure system comprising at least one gas inlet and a gas outlet;
- at least one pressure relief mechanism disposed on the at least one gas inlet;
- and
- a nebulization mechanism capable of moving to a nebulization position;
- wherein an interior pressure in the closed pressure system is changed by the at least one pressure relief mechanism.
A nebulizer in communication with a pressurized gas source and storing a liquid, the nebulizer comprising:
- a differential pressure forming structure for inputting a pressurized gas from the pressurized gas source and forming a pressure difference at an outlet portion;
- an airtight unit in gas communication with the outlet portion;
- and
- a nebulization mechanism capable of moving relative to the outlet portion of the differential pressure forming structure;
- wherein the airtight unit is configured to actuate the nebulization mechanism in response to the pressure difference.
A breath-actuated nebulization method, comprising:
- providing a nebulizer comprising a housing having a nozzle and receiving a liquid therein;
- introducing a pressurized gas from an inlet portion of the nozzle and producing a pressure difference at an outlet portion of the nozzle;
- removing gas from an airtight unit in the housing via a gas channel by the pressure difference to decrease an interior gas pressure of the airtight unit;
- and
- introducing air into the airtight unit with inspiration to increase the interior gas pressure of the airtight unit such that the liquid is drawn through a liquid channel by the pressure difference.
