Design and development of integrated high-thermal insulated placebo warming acupuncture device
The paper introduces an innovative integrated high-thermal insulated placebo warming acupuncture device.The device includes a true warming moxibustion unit and a sham warming moxibustion unit
both of which are visually identical and consist of isolation bowl
aluminum nitride plate and tripod
with the tripod equipped with sterile double-sided silicone rubber pads. During the operation of warming acupuncture technique
the true warming acupuncture moxibustion unit generates heat conduction
and th
e needle tip can be inserted into the skin
while the sham unit provides thermal insulation and its blunt needle tip is lifted immediately after contacting the skin
which merely simulates the sensation of skin penetration
so as to obtain the blinding of subjects
and simultaneously isolate the effects of acupuncture and moxibustion.Twenty healthy subjects were recruited and divided into the true warming moxibustion group (10 cases) and the sham warming moxibustion group (10 cases). The true warming moxibustion unit and the sham warming moxibustion unit were respectively used for moxibustion at the Shousanli (LI10) point on the right side. YM-HW-I medical infrared thermography system was used to capture infrared thermal images of the right upper limb of the healthy subjects to observe the changes in the surface temperature of the area where Shousanli (LI10) is located. The results showed that compared with baseline (before warming acupuncture operated)
in the true warming moxibustion group
the temperature at the right Shousanli (LI10)increased during the initial 9 minutes following the operation
and the mean temperature in the area within a diameter of 1 cm rose from the first 1 minute to 8 minutes after needling (
P
<
0.05). In the sham warming moxibustion group
except that the temperature at the acupoint and the mean temperature in the area within the diameter of 1 cm was elevated after the first 3 minutes following needling and after the first 4 minutes respectively (
P
<
0.05)
the increase of temperature at the other time points was not significant (
P
>
0.05). These findings indicate that the sham warming moxibustion device can effectively isolate most of the heat generated during moxibustion combustion
block the photothermal effects of moxibustion and basically eliminates its therapeutic effects
thereby meeting the design requirements of placebo warm needling device.
