    • The present invention provides a pneumatic injector that includes a pressurized gas source, an actuator, a driver, and a dispenser. The dispenser of the injector includes a reservoir for containing a desired amount of a chosen medicament and a needle, such as a hypodermic needle, suitable for subcutaneous, intramuscular, or intra-articular delivery of the chosen medicament. The actuator actuates the transmission of pressurized gas from the pressurized gas source to the driver, and as pressurized gas is delivered to the driver, the driver exerts at least an injection force. The injection force is of sufficient magnitude to expel a chosen medicament through the needle of the dispenser within a desired amount of time. Advantageously, the design of the injector of the present invention is extremely flexible, allowing the injector to the designed to deliver a wide range of medicaments in virtually any human or veterinary context calling for the injection of the subcutaneous, intramuscular, or intra- articular injection of medicament.
    • 本发明提供了一种气动注射器,其包括加压气体源,致动器,驱动器和分配器。 注射器的分配器包括用于容纳所需量的所选择的药物和适合于皮下,肌肉内或关节内递送所选择的药物的针(例如皮下注射针)的储存器。 致动器致动将加压气体从加压气体源传输到驱动器,并且当加压气体被输送到驾驶员时,驾驶员施加至少一个注射力。 注射力足够大,以在期望的时间内通过分配器的针排出所选择的药物。 有利地,本发明的注射器的设计是非常灵活的,允许注射器被设计成在几乎任何人类或兽医背景下递送广泛的药物,其要求注射皮下,肌肉内或关节内注射 的药物。
