Hidden needle type double-blind experimental device for evaluating acupuncture curative effect

Abstract

The invention relates to a hidden needle type double-blind experimental device for evaluating the acupuncture curative effect. The device comprises a base and a needle tube vertically arranged in the center of the base. The device is characterized in that the needle tube is composed of an outer sleeve and an inner sleeve inserted into the outer sleeve, and the inner wall of the outer sleeve is in clearance fit with the outer wall of the inner sleeve; the upper end face of the outer sleeve is flush with the upper end face of the permanent magnet ring; magnetic conductive metal wires are arranged in the pipe wall or on the inner wall of the inner sleeve in the length direction, and the two ends of the magnetic conductive metal wires are flush; the attraction between the permanent magnet ring and the magnetic conductive metal wire enables the inner sleeve to stay at any position of the outer sleeve, and test needles with different lengths can be hidden in the needle tube. The device not only can share the placebo needle and the treatment needle, but also is good in shielding effect and convenient in needle insertion operation.

Description

technical field [0001] The invention relates to a physical therapy device, in particular to an acupuncture device for positioning or stimulating specific reflex points of a human body for physical therapy. Background technique [0002] Randomized controlled clinical trials are currently the most rigorous scientific method for evaluating the clinical effects of medical interventions. A thorny issue facing clinical trials of acupuncture treatment is the design and selection of placebo controls. The ideal placebo needle in acupuncture clinical trials meets the following conditions: (1) it has no or only minimal specific therapeutic effect, which does not affect the accurate evaluation of the effect of acupuncture and moxibustion; (2) all aspects are consistent with the treatment measures Blind research can be achieved successfully; (3) The placebo injection should not affect the necessary manipulation of the treatment needle, and must ensure the realization of the normal therap...

Problems solved by technology

It can be seen from the above-mentioned scheme of this utility model patent application that it obviously has the following defects: 1. "The connection between the needle handle and the bayonet of the corresponding sleeve is through the transition fit connection of the threaded surface", although "the needle can be fixed on the It stays at a high height and will not bounce back or fall", but the needle can only be inserted along the thread by twisting the needle handle, and the needle insertion speed is obviously limited by the thread; 2. The needle handle of the real needle and the fake needle is set Screw threads, false needles are provided with connectors (such as springs) in the middle of the needle body, so the real needles and false needles must be customized, which will undoubtedly increase the cost; Therefore, it is necessary to customize the length of the needle body or the length of the cannula according to the depth of the current acupoint; 4. The real needle must pierce the sticker at the bottom of the cannula during treatment, which will obviously pollute needle body
