Two Ryodoraku needles, contained in pen cases, as developed by Dr Yoshio Nakatani for application to acupuncture points of high electrical conductivity, from the surgery of a British practitioner c.1996, unsigned, Japanese, 1980-1985.

Ryodoraku is a diagnostic technique within acupuncture. It assesses electrical imbalances within the body. These needles are contained in pen cases. They were developed by Dr Yoshio Nakatani for application to acupuncture points of high electrical conductivity.

Dr Nakatani established a theory that 12 meridians exist in the human body. The acupuncturist taps into these energy pathways to look for electrical fluctuations. They believe these indicate disturbances in the flow and balance of a life force known as qi (chi). TCM practitioners believe a balanced qi is essential for wellbeing.
