ABSTRACT:
A safety syringe including a hollow barrel member having a substantially cylindrical shaped plunger receiving cavity formed therethrough, the plunger receiving cavity terminating in a plunger receiving opening at a first end thereof and a cavity bottom member having a needle mounting portion at a second end thereof, the needle mounting portion being centrally oriented on the cavity bottom member and secured thereto by a breakaway plastic bridge seal, the needle mounting portion having a fluid port member having a cavity facing opening including at least one plunger engagement member extending from a defining sidewall thereof; and a plunger member having a plunger shaft a plunger bulb in connection with an end thereof that has a needle portion engagement member adapted to engage the plunger engagement member when the needle portion engagement member is inserted into the cavity facing opening. The resulting engagement between the needle portion engagement member and the plunger engagement member is of sufficient strength to allow a force generated by pulling on the plunger to cause the needle engagement portion to break free from the cavity bottom member by breaking the bond created by the breakaway bridge seal between the needle portion and the cavity bottom member.
