摘要
A needle free injector system and a method for delivering a formulation using this system are disclosed. The method comprises actuating a needle free injector to pressurize a liquid formulation and force the formulation through an orifice in a skin puncture phase followed by injection of the formulation during a delivery phase. The skin puncture phase is defined by a pressure profile vs. time curve after actuation which has a main pressure peak with a maximum pressure. The delivery phase occurs at a lower pressure than the maximum pressure of the main peak pressure. The device may have one or more orifices and pressurizing the formulation during the puncture phase and delivery phase to extrude the formulation through each orifice is structured so as to improve characteristics of needle free delivery.
