Abstract
An adapter for use with an injection device includes a first end, a second end and a first longitudinal axis extending from the first end and the second end. The adapter also includes a chamber defined by a sidewall between the first end and second end and a nozzle having a passageway extending through the sidewall, the passageway having an input at the chamber, an output at an outer surface of the body and a passageway axis extending from the input to the output, the passageway axis being angularly offset from the longitudinal axis of the channel. A cartridge can include such an adapter.
Claims19
An adapter for use with an injection device, the adapter comprising a body including:
- a first end, a second end and a first longitudinal axis extending from the first end and the second end,
- a chamber defined by a sidewall between the first end and second end,
- a nozzle having an input, an output opening, and a passageway from the input to the output opening, the passageway having an injection axis extending through the input and the output opening and to an outer surface of the body, the output opening and the injection axis being angularly offset from the first longitudinal axis of the body;
- wherein the output opening of the nozzle is spaced from an injection site during injectate delivery to the injection site, and wherein a plunger is configured to fit into a depression of the adapter in which the injectate pools prior to ejection.
A cartridge for administering an injectate to a target underlying a contact surface, the cartridge having a distal end and comprising:
- a housing having an axis extending from a proximal end to a distal end of the housing, the housing having a bore extending along a first longitudinal axis from the proximal end to the distal end, an outer surface, and an opening at the distal end of the housing;
- an adapter disposed at the distal end of the housing, the adapter including a body having:
- a first end, a second end and a second longitudinal axis extending from the first end and the second end and substantially in parallel with the first longitudinal axis;
- a chamber defined by a sidewall between the first end and second end,
- a nozzle having a passageway, the passageway having an input at the chamber, an output opening, and an injection axis extending from the input to the output opening, the injection axis and the output opening being angularly offset from the first longitudinal axis;
- wherein the output opening of the nozzle is spaced from an injection site during injectate delivery to the injection site, and wherein a plunger is configured to fit into a depression of the adapter in which the injectate pools prior to ejection.
