Syringe with Spinal Needle -
This is a large capacity syringe with a long needle attached. In some abortion procedures it is used to drain off amniotic fluid from the mother's uterus and replace it with either a saline or urea solution. However, its more common use is for injecting chemical agents (digoxin, potassium chloride, etc.) into the heart of the baby.
In both instances, these chemicals serve two purposes. First, their use greatly reduces the chance that the baby might be born alive. And second, these chemicals soften the child's corpse and make it easier to rip apart and/or remove.
