Abstract:
PROBLEM TO BE SOLVED: To provide a needleless injection device that forms an appropriate state of contact between an injection port from which a substance to be injected is injected and an injection object.SOLUTION: A needleless injection device includes an inflatable bag body arranged so as to surround an outer peripheral surface of an injection object, a needleless syringe without an injection needle, and a gas supply device for supplying inflation gas to the bag body. The needleless syringe includes a nozzle part for injecting a substance to be injected toward the injection object surrounded by the bag body, whose injection port is in a state of facing the injection object. The bag body includes a first bag part which is any region other than a region where the needleless syringe is disposed, and is arranged so as to pressurize the injection object by inflation, and a second bag part arranged in a region to sandwich the nozzle part between the injection object and itself so as to press the injection port to the injection object side by inflation.SELECTED DRAWING: Figure 1
