摘要：
A needle-free transdermal transport device for transferring a substance across a surface of a biological body includes a reservoir for storing the substance, a nozzle in fluid communication with the reservoir and a controllable electromagnetic actuator in communication with the reservoir. The actuator, referred to as a Lorentz force actuator, includes a stationary magnet assembly and a moving coil assembly. The coil assembly moves a piston having an end portion positioned within the reservoir. The actuator receives an electrical input and generates in response a corresponding force acting on the piston and causing a needle-free transfer of the substance between the reservoir and the biological body. The magnitude, direction and duration of the force are dynamically controlled (e.g.,servo-controlled) by the electrical input and can be altered during the course of an actuation cycle. Beneficially, the actuator can be moved in different directions according to the electrical input.一種用於將一物質傳送經過生物體之表面的免針頭經皮膚輸送裝置，包括有一個用於儲存該物質的儲存槽、一個與該儲存槽流體相連通的噴嘴和一個與該儲存槽相連通的可控制電磁式致動器。被稱為是羅倫玆力致動器的致動器包括有一個固定磁鐵組件和一個移動線圈組件。線圈組件是移動一個具有一被安置於該儲存槽內之末端部位的活塞。致動器接收到一個電氣輸入，以及回應地產生一個作用於活塞上的相對應作用力，並且導致該物質以免針頭之方式而被傳送於儲存槽與生物體之間。作用力的大小、方向和持續時間是藉由電氣輸入而被動態地控制住(例如是伺服控制)，並且是能夠於一作動循環之過程中被改變。有利之處是，致動器能夠依照電氣輸入而被移動於不同方向。
