摘要:
A pharmaceutical delivery apparatus with an automatic syringe retraction following a manually controlled injection. The apparatus includes a housing (28), a syringe carriage (90), a medication-filled syringe (70) held within the carriage, the syringe needle tip being disposed within the housing in a first position and projecting from the housing beyond the housing proximal end for insertion into an injection site in a second position, a manually shiftable plunger (130), means on the carriage and the housing and the plunger for causing the carriage to advance from the first position to the second position and for injecting medicine from the syringe when the plunger is manually plunged proximally toward the housing, and means on the carriage and the plunger for causing the carriage to retract from the second position to a position at which the needle tip is disposed within the housing when the plunger shifts distally.

摘要:
A delay mechanism for staging the operation of an automatic injection apparatus (20) to ensure medication contents are properly delivered prior to the needled syringe (32) of the apparatus being retracted. In one form, the delay mechanism includes a shuttle (50), a follower (110), a locking member, a damping compound, and a driver and a driver biasing element (44). The shuttle is for a needled syringe of the apparatus and includes a first latching element. The follower includes a second latching element and a cammable surface, which second latching element is for cooperating with the first latching element to limit motion of the shuttle relative to the follower in a second direction opposite the first direction. The locking member is movable from a locking position to a release position by engagement with the syringe plunger during an injection, the locking member, when in the locking position, preventing rotation of the follower relative to the shuttle, the locking member, when in the release position, allowing rotation of the follower relative to the shuttle. The damping compound is between the follower and a supporting surface to dampen rotation of the follower relative to the shuttle. The driver is rotatably fixed relative to the shuttle and includes a camming surface. The shuttle allowing retracting of the syringe needle into the housing of the automatic injection apparatus after injection.
