发明名称 Self-destructing hypodermic syringes and hypodermic plunger devices
摘要 A self-destructing hypodermic device to allow one-time use only of the device. The device includes a syringe casing, a syringe tip, and a syringe plunger; all cooperating and functioning to allow solutions or medications to be drawn into the casing, and then intravenously injected into a user. At least some part or portion of the casing, plunger, and tip is comprised of a material which self destructs, at least partially, upon contact with the medication or solution intravenously injected, rendering the device unusable after one use. In one embodiment, the self-destructing portion of the casing, plunger, or tip is comprised of a material which is at least partially soluble in the medications or solutions intravenously injected by the device. Optionally, a tip cover can be used which can grip the syringe tip after use, to assist in disabilitating the device after one use.
