Abstract
The object of the present invention is to provide an injection tool that permits a predetermined dose of drug to be administered accurately at an intended site of a very small range that is located comparatively deep within the body and which develops comparatively high internal pressure, as well as a method for use thereof; in its constitution, the present invention relates to an injection tool characterized by comprising an injection device comprising an injection barrel and an injection needle that is to be mounted at the distal end thereof, a piercing hollow needle having a connector portion that is to be connected to the aforementioned injection device and a needle portion that allows the aforementioned injection needle to be inserted therethrough almost tightly, and an inner needle having a basal portion that is to be fitted tightly in the aforementioned connector portion and a solid needle that is to be inserted almost tightly in the aforementioned needle portion, as well as a method of using an injection tool that is characterized in that a solid needle is inserted almost tightly in the needle portion of a piercing hollow needle having a connector portion that is to be connected to an injection device comprising an injection barrel and an injection needle mounted at the distal end thereof and said needle portion that enables the injection needle of the aforementioned injection device to be inserted therethrough almost tightly and, at the same time, the aforementioned needle portion is allowed to pierce to a predetermined site in the body of interest with an inner needle having said solid needle being fixed in said piercing hollow needle and, subsequently, said inner needle is withdrawn and the injection needle of the aforementioned injection device is passed through said needle portion while, at the same time, the aforementioned injection device is connected to the aforementioned connector portion and, thereafter, the substance to be injected that is held within the aforementioned injection barrel is injected into said body of interest.
