Abstract
A needle-free injection device including an outer housing, and an inner housing. The inner housing is moveable within the outer housing between a syringe loading position and a firing position. The needle-free injection device also includes a syringe mount to receive a needle-free syringe at one end of the inner housing. The syringe mount includes an interlocking structure cooperating with the inner housing and outer housing to prevent placement of the needle-free syringe into engagement with the syringe mount unless the inner housing is in the syringe loading position.
Claims20
A needle-free injection device comprising:
- an outer housing;
- an inner housing, the inner housing being moveable within the outer housing between a syringe loading position and a firing position;
- a syringe mount configured to receive a needle-free syringe at one end of the inner housing;
- and
- an eject button in mechanical communication with the syringe mount such that activation of the eject button causes the syringe mount to release a mounted needle-free syringe.
A needle-free injection device comprising:
- a syringe mount configured to receive a needle-free syringe, the syringe mount comprising a socket sized to receive the needle-free syringe and at least one pawl adjacent to the socket and configured to grip the needle-free syringe;
- and
- an ejection mechanism in mechanical communication with the syringe mount such that activation of the ejection mechanism causes the syringe mount to release a mounted needle-free syringe.
A needle-free injection device comprising:
- a syringe mount configured to receive a needle-free syringe;
- and
- an ejection mechanism in mechanical communication with the syringe mount such that activation of the ejection mechanism causes the syringe mount to release a mounted needle-free syringe, the ejection mechanism including:
- an ejection spring;
- and
- an eject button, wherein activation of the eject button causes the ejection spring to decompress to eject a mounted needle-free syringe from the syringe mount.
