ABSTRACT:
A breakable syringe with a safety sleeve has a syringe body (10), a needle (13) with a needle base (12), a safety sleeve (20), and a breaking device. The needle (13) is attached to the syringe body (10) by inserting the needle base (12) into the syringe body (10). The safety sleeve (20) slidably sleeves the syringe body (10) and clamps the breaking device with the syringe body (10). By sliding the safety sleeve (20), the safety sleeve (20) can be selectively positioned at different locations to expose or enclose the needle (13) by the multiple engaging devices and even to urge the breaking device to break the syringe body (10). Therefore, the needle (13) of the syringe is conveniently enclosed and the syringe can be immediately broken after use.
