Document Type and Number:
Japanese Patent JP7282750
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide an injection needle and an injection device which are capable of adjusting the puncture depth of a needle. The present invention is equipped with: a needle; a needle base holding the needle such that the needle protrudes from the distal end side; and an adjuster provided on the outer periphery of the needle base so as to be movable in the axial direction of the needle base. By adjusting the axial-direction position of the adjuster, the protrusion length of the needle can be adjusted. Consequently, the puncture depth of the needle can be adjusted, and there is no need to prepare a plurality of type of injection needles having different protrusion lengths.
