A safety syringe includes a main body, an injection needle and a carrying base. A slot is formed on the main body. The injection needle includes a first needle part configured to connect to an infusion tube for communicating the injection needle to the infusion tube, and a second needle part bent relative to the first needle part. The carrying base is arranged on the main body, for carrying the injection needle. Wherein, when the carrying base is located at an initial position, the second needle part is exposed outside the main body and when an external force applied to the carrying base is greater than a predetermined level, the carrying base is capable of rotating a predetermined angle relative to the main body, for accommodating the second needle part inside the slot.安全注射裝置包含一本體,一注射針,以及一承載座。該本體上形成有一凹槽。該注射針包含一第一針部用以連接於一輸液管,以使該注射針連通於該輸液管,以及一第二針部相對該第一針部彎折。該承載座是設置於該本體上,用以承載該注射針。其中當該承載座位於一初始位置時,該第二針部是外露於該本體;以及當施加於該承載座之一外力大於一預定值時,該承載座係可相對該本體旋轉一預定角度,以使該第二針部被容置於該凹槽中。100‧‧‧安全注射裝置110‧‧‧本體112‧‧‧本體第一端114‧‧‧本體第二端116‧‧‧凹槽120‧‧‧注射針122‧‧‧第一針部124‧‧‧第二針部130‧‧‧承載座132‧‧‧第一承載部134‧‧‧第二承載部140‧‧‧轉軸150‧‧‧外套152‧‧‧套體154‧‧‧握持部
