Safety housing based implant/medicament injecting system

A safety housing based implant/medicament injecting system comprising:

• a housing comprising a cylindrical barrel with a housing cap at a front end of the cylindrical barrel and an opening defined in the housing cap;
• a needle assembly fully accommodated within the housing and supported by a spring positioned between the housing cap and a front end of the needle assembly, said needle assembly includes
• a needle hub comprising a cannula at the front end of the needle assembly;
• a label holder at a back end of the needle assembly;
• an implant/medicament container positioned in an axially symmetric manner between the label holder and the needle hub;
• and
• a plunger rod guide running through the implant/medicament container;
• a plunger means comprising a plunger and a plunger rod, said plunger means is configured for:
• an initial forward motion of the plunger to eject the cannula through the opening, wherein a safety clip at a back end of the housing operatively couples the plunger and the plunger rod with the label holder of the needle assembly and a first engagement means engages the needle hub with the housing at an end of the initial forward motion of the plunger;
• and
• a subsequent continuing forward motion to inject the implant/medicament through the ejected cannula when a seal releasing means operates on the safety clip for removal of the safety clip which disengages the label holder from the plunger, wherein the plunger rod guide enabling the plunger rod to move through said plunger rod guide and push the implant/medicament towards the needle hub;
• a first disengagement means for disengaging the first engagement means;
• and
• a second engaging means to permanently arrest the needle assembly in the housing after use;
• wherein the safety clip comprising a first end coupled with both the housing and the label holder and a second end externally coupled with the plunger by using a positive lock.
