Abstract
A resettable injection training device for simulating an injection is provided in an embodiment herein. The device may include an outer housing, a safety shield having a proximal end and a distal end, the distal end for engaging with a target surface during an injection simulation, the safety shield comprising a retracted position, an extended unlocked position and an extended locked position, a plunger; and a locking tab for interfacing with the safety shield for interfacing with the safety shield the extended locked position, wherein if the safety shield distal end disengages from the target surface during an injection simulation, the safety shield extends to the extended, locked position until the device is reset.
Claims24
A resettable injection training device for simulating an injection, comprising:
- an outer housing;
- a safety shield comprising a proximal end and a distal end, said distal end for engaging with a target surface during an injection simulation, the safety shield comprising a retracted position, an extended unlocked position and an extended locked position;
- a plunger;
- and
- a locking tab for interfacing with the safety shield for interfacing with the safety shield the extended locked position,
- wherein if the safety shield distal end disengages from the target surface during an injection simulation, the safety shield extends to the extended, locked position until the device is reset.
A resettable injection training device for simulating an injection, comprising:
- an outer housing;
- a safety shield comprising a proximal end and a distal end, said distal end for engaging with a target surface during an injection simulation, the safety shield comprising a retracted position, an extended unlocked position and an extended locked position;
- a plunger;
- an actuation member;
- and
- a locking tab;
- wherein proximal movement of the safety shield followed by activation of the actuation member actuates the device, and wherein an out of sequence operation of the device, comprising activation of the actuation member followed by proximal movement of the safety shield causes resistance during operation.
A resettable injection training device, comprising:
- an outer housing, comprising a proximal end and a distal end;
- a safety shield, comprising a proximal end and a distal end and being slidable relative to the outer housing between an extended unlocked position, a retracted position, and an extended locked position;
- a plunger slidable relative to the outer housing between a retracted position and an extended position;
- an actuation member associated with the proximal end of the inner housing, comprising an unlocked position and a locked position, said actuation member being unlocked when the safety shield is in the retracted position;
- an actuation member collar for locking the actuation member when the safety shield is in an extended locked position or an extended unlocked position;
- a rotatable plunger collar for interfacing with the actuation member and the plunger, such that depression of the actuation member rotates the plunger collar to release the plunger to the extended position;
- wherein a pressure on the safety shield distal end slides the safety shield from the extended unlocked position to the retracted position, rotating the actuation member collar to unlock the actuation member, such that depression of the actuation member releases the plunger to the extended position, and wherein following release of the pressure on the safety shield distal end, the safety shield extends to the extended locked position and the actuation member is reset to its locked position.
