| 摘要 |
The invention provides an auto-destructible syringe comprising a syringe barrel having an inner wall, a proximal end, and a distal end; a plunger slidably disposed within the syringe barrel; stopper means on the inner wall of the syringe barrel for preventing the syringe plunger from moving towards the distal end; grooves on the plunger alignable with the stopper means by axially rotating the plunger relative to the barrel; and cutting means connected to the plunger. When the stopper means are aligned with the grooves, the plunger can move toward the distal end of the syringe barrel. The cutting means cut the barrel when the plunger moves toward the distal end of the syringe barrel perforating the syringe barrel and preventing subsequent use of the syringe.
