Drug delivery device

A drug delivery device for administration to a subject includes a reservoir containing an active pharmaceutical ingredient and a potential energy source. The drug delivery device also includes a trigger operatively associated with the potential energy source, where the trigger is configured to actuate at a predetermined location within the subject. The drug delivery device also includes a rupturable membrane disposed along a flow path extending between the reservoir and an outlet, where the membrane is configured to rupture when the trigger is actuated. Once the trigger is actuated, potential energy from the potential energy source may be released to expel the active pharmaceutical ingredient in the form of a jet through the outlet. 一种用于施用于受试者的药物递送装置包含储器，所述储器容纳活性药物成分和潜在能源。所述药物递送装置还包含触发器，所述触发器与所述潜在能源操作性地相关联，其中所述触发器被配置成在所述受试者体内的预定位置处致动。所述药物递送装置还包含可破裂膜，所述可破裂膜沿着在所述储器与出口之间延伸的流动路径安置，其中所述膜被配置成当所述触发器被致动时破裂。一旦所述触发器被致动，就可以释放来自所述潜在能源的潜在能量，以通过所述出口以射流的形式排出所述活性药物成分。
