Abstract:
1. A bioinjection device for delivering medicament into bone tissue, comprising: a housing having a grip and an elongated barrel extending away from the grip, the barrel having a bore; a trigger pivotally mounted on the housing; a plunger having a distal end, the plunger movable between a first position in which the distal end is retracted within the bore of the elongated barrel and a second position in which the distal end extends beyond the bore; a needle located within the plunger; a retaining member disposed about an opening of the bore, the retaining member receiving a cartridge containing a medicament, wherein the cartridge has opposed forward and rear ends, the rear end being formed from a membranous material so that the needle pierces the membranous material to release the medicament; and a spring-biased actuation mechanism coupling the trigger with the plunger, wherein the plunger moves from the first position to the second position when the trigger is actuated; and wherein the forward end of the cartridge forms an engaging member and the rear end has a recess defined therein so that a plurality of the cartridges are stacked together with the engaging member of one of the cartridges being received within a corresponding recess of an adjacent one of the cartridges.
