This device is an auxiliary device with reasonable design for placebo acupuncture research, so as to make double-blind placebo acupuncture control possible. This new auxiliary acupuncture device includes an acupuncture device and a placebo acupuncture device with exactly the same appearance. Both of them are composed of a hemispherical base and a telescopic tube. Through the rotation of the telescopic tube in the notch of the base, the insertion angle of needles can be adjusted from 15 degrees to 165 degrees. The operation of twisting and lifting and inserting can be carried out through the horizontal rotation and vertical sliding of the telescopic tube. A silicone needle pad is arranged in the base, which can simulate the blocking feeling of skin and muscle during needle insertion. The bottom of the base is attached with hydrogel, which has good fixity. The auxiliary device is applicable to multiple parts of the human body and can effectively reduce the risk of unblinding.
为安慰针刺研究设计合理的辅助装置，使双盲安慰对照成为可能。此新型辅助针刺装置包括外观完全一致的真针刺装置与安慰针刺装置，两者均由半球形底座与伸缩管构成，通过伸缩管在底座槽口内的转动，实现在15°~165°范围内调整进针角度，通过伸缩管的水平转动和垂直滑动可进行捻转和提插手法的操作；底座内部设置有硅胶针垫，能够模拟进针时皮肤、肌肉所产生的阻滞感；底座底部附有水凝胶，具有良好的固定性。该辅助装置适用于人体多个部位，可有效降低盲底泄露的风险。.
