ABSTRACT:
A safety hypodermic syringe includes a hypodermic needle fixedly connected to holder plate and constantly supported by a spring means for making axial movement, which holder plate is normally retained by a clamping means at a ready position for injection. When a plunger is pushed to the front limit, the hypodermic needle becomes released from the constraint of the clamping means and pushed by the spring means to drop and to further follow a rubber plug to be squeezed into the inner chamber of the plunger so as to isolate from outside and to prevent from pricking accident or possible body fluid contact.
