Abstract
The present invention relates to an improved needleless hypodermic injection device (10). Accordingly, the needleless hypodermic injection device (10) includes: (a) an injector (12) having a housing (13) formed by first and second housing sections; (b) a spring injector mechanism (14) in associated with a piston (16) disposed within the injector (12); (c) a trigger (20) having a stopper (22) and in associated with a return spring (23) pivotally mounted to the injector (12); (d) a safety lock (30) slidably attached to the injector (12) to prevent undesired release movement of the trigger (20); wherein the piston (16) is in associated with a compression spring (15) and is capable to provide two different setting of spring loaded force for both low and height doses injection.
