Elastic acupuncture needle: a set of one-piece elastic double-blind placebo acupuncture
a set of clinical device used in randomized controlled trials of acupuncture is developed
which may potentially obtain the double-blind placebo control. This kind of acupuncture device consists of a real needle and a sham one (placebo needle) with a identical appearance. Either of the needle is composed of an integrated cap-type handle and needle body
and a sterile double-sided adhesive pad is designed on the bottom for fixation. A spring with miniature low profile
is built in sham needle. During operation
the real needle can be normally inserted
while the sham one be retracted because of the elasticity generated by the pressure on the skin
but
deqi
can still be felt by patients whenever the force difference between the skin and the spring reaches a certain balance. The rubber pad designed in this acupuncture needle can simulate the "resistance" felt by operators during needle insertion so that the double blinding is actualized in terms of the appearance and sensations.
