摘要： The present invention relates to a microjet drug delivery system for microjet spraying a drug solution stored inside to inject the same into the bodily tissue of a person to be operated, and a microjet injector. The microjet injector comprises: a pressure chamber completely filled with the liquid for propelling pressure, having an accommodation space with one side opened; an elastic film, which is a film member made of an elastic material, arranged so as to form a closed space by closing the opened one side of the pressure chamber; a drug chamber for accommodating a drug solution in a predetermined inner space, provided adjacent to the pressure chamber with interposing the elastic film therebetween; and a microjet nozzle communicating with the inner space of the pressure chamber so as to be formed as a channel for allowing the drug solution stored inside the pressure chamber to be microjet sprayed to the outside. The microjet drug delivery system provided by the present invention comprises: the microjet injector; an energy focusing device for generating bubbles in the liquid for propelling pressure stored in the pressure chamber by applying a concentrated energy to the liquid for propelling pressure; and a connecting adaptor for selectively detachably coupling the microjet injector to the energy focusing device.
