    • A system for injecting a fluid medicament into a patient includes a drive mechanism, and a cassette loaded with a pre-filled hypodermic syringe. When the cassette is loaded, the syringe is held firmly inside and the cassette can be selectively engaged with the drive mechanism. The drive mechanism has two motors. A first motor initially moves the hypodermic syringe from a position inside the cassette where its needle is concealed, to a position where the needle extends from the cassette for insertion into a patient for an injection. With the needle inserted, a second motor pushes the syringe stopper to expel a fluid medicament from the syringe. After an injection, the first motor withdraws the syringe back into concealment inside the cassette, to again firmly hold the syringe on the cassette. The cassette and syringe, in combination, can then be removed from the drive mechanism and discarded.
    • 用于将流体药物注射到患者体内的系统包括驱动机构和装有预填充的皮下注射器的盒。 当盒子被装载时,注射器被牢固地保持在内部,并且盒子可以选择性地与驱动机构接合。 驱动机构有两个电机。 第一马达首先将皮下注射器从其中隐藏的针的盒内部的位置移动到针从盒延伸以插入患者以进行注射的位置。 在针插入的情况下,第二马达推动注射器止动器以从注射器排出流体药物。 注射后,第一台电机将注射器放回盒内的隐藏状态,再次将注射器固定在盒式磁带上。 组合的盒式磁带和注射器然后可以从驱动机构移除并被丢弃。
