cone flange 64 is shown fixed to the proximal end of the needle cannula 8 the distal end of the biased spring 13 is thrusting on the cannula flat 12 and the proximal end of the biased spring is shown thrusting on the distal end if the spring foundation 65 the barrier module 61 is restraining the biased spring from thrusting the needle cannula into the syringe module 2 or plunger 1 the pop out plunger plug 60 is shown supported laterally and some axially the stop hooks 63 are holding the plug stop 62 to further prevent the pop out plunger plug 60 from popping out under pressure the plunger 1 is shown inside of the syringe module 2 the barrier support 54 is shown in alignment with the frangible ring 77 the barrier support 54 is shown with a slop 84 at the distal end to place a concentrated load on the frangible ring 77 referring to fig4 there is shown an elongated section elevation of the plunger being thrust in a distal direction 38 the distal end of the barrier support 54 has come in contact with the frangible ring 77 and exerted a concentrated load or point load on the frangible ring 77 the frangible ring 77 has broken and the frangible plate no longer restrains the thrust of the biased spring 13 and the biased spring is now thrusting on the spring foundation 65 needle cannula 8 and the cone flange 64 as the cone flange is released it is thrust into.
