Abstract
A dual fluid cartridge assembly includes a cartridge, a flange, and a piston tube. The cartridge defines a channel and includes an flange. The flange defines a cavity that extends from a cavity opening to a cavity base. The cavity opening is positioned within the channel of the cartridge, and the cavity base is positioned external to the cartridge. The piston tube has an extended end, and is positioned at least partially within the channel. The extended end is positioned within the cavity.
Claims21
A dual fluid cartridge assembly, comprising:
- an outer cartridge that extends in an axial direction from a proximal end to a distal end, the outer cartridge comprising:
- a base wall having an inner edge, the base wall being positioned toward the distal end of the outer cartridge;
- and
- a flange extending at least partially along the inner edge of the base wall, the flange defining a cavity that extends in the axial direction from a cavity opening to a cavity base,
- wherein the cavity base is distal to the base wall in the axial direction;
- and
- a piston tube having an extended end positioned within the cavity.
A dual fluid cartridge assembly, comprising:
- an outer cartridge that extends in an axial direction from a proximal end to a distal end, the outer cartridge comprising:
- a base wall having an inner edge that defines a cartridge outlet, and
- a flange extending at least partially along the inner edge of the base wall, the flange defining a cavity that extends in the axial direction from a cavity opening to a cavity base,
- wherein the base wall is distal to the cavity opening in the axial direction, and wherein the cavity base is distal to the base wall in the axial direction;
- and
- a piston tube having an extended end positioned within the cavity.
A dual fluid cartridge assembly, comprising:
- a cartridge defining a channel;
- a flange coupled to the cartridge, the flange defining a cavity that extends from a cavity opening to a cavity base, the cavity opening being positioned within the channel of the cartridge, the cavity base being positioned external to the cartridge;
- and
- a piston tube having an extended end, the piston tube being positioned at least partially within the channel, and the extended end being positioned within the cavity.
A dual fluid cartridge assembly, comprising:
- an outer cartridge for carrying a first fluid, the outer cartridge comprising:
- a cylindrical outer wall that defines a channel,
- a base wall having an inner edge that defines a cartridge outlet, and
- a flange extending at least partially along the inner edge of the base wall, the flange defining a cavity that extends in an axial direction from a cavity opening to a cavity base,
- wherein the base wall is distal to the cavity opening in the axial direction, and wherein the cavity base is distal to the base wall in the axial direction;
- an upper seal positioned within the channel, the upper seal configured to seal said first fluid in said outer cartridge;
- an inner cartridge for carrying a second fluid;
- and
- a piston tube having an extended end, the piston tube being positioned at least partially within the channel, and the extended end being positioned within the cavity, the piston tube configured to provide a fluid flow path from said inner cartridge to said cartridge outlet.
