Document Type and Number:
Japanese Patent JP7368599
Kind Code:
B2
Abstract:
A drug solution injection needle includes: a distal end member being a sharp member and made of metal; a connecting tube having electrical insulating properties connected to a base end side of the distal end member; a metal tube connected to a base end side of the connecting tube; and an insulating layer covering an outer circumferential surface of a base end portion of the metal tube. The connecting tube and/or the distal end member includes at least one hole communicating with a cavity of the drug solution injection needle and open to an outer surface of the connecting tube or the distal end member, and an electrode configured to measure electric potential is formed by a distal end portion of the metal tube not covered by the insulating layer.
