Embodiment Construction

[0057] The present invention may be contained within any suitable housing, such as that shown in FIG. The opposite end has a release mechanism 20 for releasing the spring 14 which deploys and empties the contained syringe.

[0058] figure 2 The key building blocks for the preferred embodiment of the preferred housing are shown schematically.

[0059] The drive spring 30 engages a first engagement element 32 which itself provides power to a second engagement element 34 . The drive spring 30 thus acts here as a movement-generating means for the injection device. Alternatively, motion generating components such as pneumatic pistons operated by compressed gas tanks or actuators of electromagnetic coils in electric devices may be used. The second engagement element 34 is arranged to engage the dispensing piston 18 of the syringe 4 in the device. Thus, when the engagement elements 32, 34 are released by a suitable release mechanism, the drive spring 30 drives the first engageme...

Abstract

An injection device including a housing for containing a syringe (4) having a dispensing piston (18) to expel the contents of the syringe through the needle (8), a resilient member (40) for biassing the syringe and the needle inwardly off the housing, a first coupling element (32) moveable towards said one end so as to move the needle of the syringe out of the opening and to move the dispensing piston of the syringe towards the end of the surface, a mechanism operable to release the syringe such that the needle moves inwardly off the housing,; a drive coupling for extending from said first coupling element to the dispensing piston of the syringe so as to transfer movement of said first coupling element to the dispensing piston wherein the mechanism is triggered to release the syringe and includes components to delay release of the syringe until a predetermined period after being triggered such that it can be ensured that the dispensing piston reaches the end surface before the syringe is released.

Description

technical field [0001] The present invention relates to an injection device, and more particularly, to an injection device that automatically retracts the needle of the syringe after dispensing the contents of the syringe. Background technique [0002] There are devices that are spring loaded to automatically extend the needle of the syringe from the device, dispense the contents of the syringe and then automatically retract the needle. Such a device is described in WO 95 / 35126. [0003] As shown in FIG. 1 of the accompanying drawings, the device comprises a housing 2 housing a syringe 4 . The housing 2 comprises an opening 6 through which the needle 8 of the syringe 4 can protrude. Return spring 10 biases syringe 4 away from opening 6 . The device also comprises a drive element 12 biased by a spring 14 to drive an adapter 16 and thereby move a dispensing piston 18 of the syringe 4 . In use, the release mechanism 20 releases the drive element 12 so that the syringe 4 is ...
