WIPO Patent Application WO/2018/139668
Kind Code:
A1
Abstract:
An injection device that comprises a detection unit and a puncturing unit. The detection unit comprises: an electrode that can detect the electrical characteristics of biological tissue; and a first tracking mechanism that tracks the movement of the biological tissue. The puncturing unit can puncture the biological tissue and administer a substance-to-be-administered to the biological tissue through a hollow part that is demarcated inside the puncturing unit. The position of the puncturing unit can be specified on the basis of the position of the electrode. The puncturing unit comprises a second tracking mechanism that tracks the movement of the biological tissue. The second tracking mechanism comprises a needle member and an impelling member that impels the needle member toward the distal-end side of the needle member and can expand and contract in the extension direction of the needle member in association with the movement of the needle member in the extension direction thereof.
