ABSTRACT:
The device comprises a base plate and a cover plate held in spaced, parallel relation by a pair of spaced, parallel side walls. A rectangular rib, which extends between the sidewalls approximately midway between the base and cover plates, has therein a central, circular opening which registers coaxially with like openings in the base and cover plates. A cocking bar, which is reciprocable between the side walls beneath the rib, has a central opening movable into and out of registry with the opening in the rib. In use, the cocking bar is shifted to offset its opening slightly from the opening in the rib; and a syringe is inserted, needle-down, through the openings in the cover plate, rib and cocking bar, but with the lower end of the syringe barrel or housing seated on a marginal portion of the cocking bar around its now-offset opening. A resilient member is placed over a shoulder on the upper end of the syringe housing, so that when the opening in the base plate is positioned over the spot into which the needle is to be inserted, the operator needs only to shift the cocking bar slightly to register its opening with that in the rib. The lower end of the syringe thus slides off the retaining portion of the cocking bar and is urged suddenly down to project its needle through the opening in the base plate and into the operator's body.
