Abstract
Cartridges have a cartridge body configured to store a formulation, a formulation valve disposed in the cartridge body, and an air valve disposed in the cartridge body. The cartridge is configured to dispense the formulation through the formulation valve when the formulation valve and the air valve are each in an open state, and to not dispense the formulation when the formulation valve and the air valve are in a closed state.
Claims16
A cartridge, comprising:
- a cartridge body configured to store a formulation;
- a formulation valve disposed in the cartridge body;
- and
- an air valve disposed in the cartridge body,
- wherein the cartridge is configured to dispense the formulation through the formulation valve when the formulation valve and the air valve are each in an open state, and to not dispense the formulation when the formulation valve and the air valve are in a closed state, wherein a liquid formulation moves freely within the cartridge body, and the formulation valve is disposed on a side of the cartridge where the liquid formulation accumulates within the cartridge body, wherein the formulation valve and the air valve are biased toward the closed state, wherein the air valve is biased toward the closed state by a spring, and wherein the spring pushes an air valve seat toward an air valve body.

A cartridge, comprising:
- a cartridge body configured to store a formulation;
- a formulation valve disposed in the cartridge body;
- and
- an air valve disposed in the cartridge body,
- wherein the cartridge is configured to dispense the formulation through the formulation valve when the formulation valve and the air valve are each in an open state, and to not dispense the formulation when the formulation valve and the air valve are in a closed state, wherein a liquid formulation moves freely within the cartridge body, and the formulation valve is disposed on a side of the cartridge where the liquid formulation accumulates within the cartridge body, wherein the formulation valve and the air valve are biased toward the closed state, wherein the air valve is biased toward the closed state by a spring, further comprising a cartridge cap that couples with the cartridge body, the cartridge cap contacting the spring.

A system, comprising:
- a nebulizer;
- and
- a cartridge configured for reversible coupling with the nebulizer, the cartridge comprising:
- a cartridge body configured to store a formulation;
- a formulation valve disposed in the cartridge body;
- and
- an air valve disposed in the cartridge body,
- wherein the cartridge is configured to dispense the formulation to the nebulizer through the formulation valve when the formulation valve and the air valve are in an open state, and to not dispense the formulation when the formulation valve and the air valve are in a closed state, wherein a liquid formulation moves freely within the cartridge body, and the formulation valve is disposed on a side of the cartridge where the liquid formulation accumulates within the cartridge body, wherein the formulation valve and the air valve are biased toward the closed state, wherein the air valve is biased toward the closed state by a spring, and wherein the spring pushes an air valve seat toward an air valve body.
