Acupoint Catgut-embedding therapy (ACET) is considered an advanced method for the treatment of juvenile pseudomyopia. However, the existing test methods of ACE monofilaments cannot meet the desire for accurate measurement and convenient operation. This paper presents a study of the compression behaviors of ACE monofilaments developed for the human body. To investigate a convenient and accurate test method for monofilaments, different materials, including polypropylene (PP), polylactic acid (PLA) and polyglycolide acid (PGA), were designed to a curved rod shape based on the three-point bending model used in this work. Variables, including the number of winding laps, the diameter of the compression platens and the compression rate of specimens, were discussed by the platform compression method. Properties such as radial force, the compression modulus and recovery ratio were also tested and analyzed. The results revealed that the winding lap of 25r was selected as the most suitable number according to the principles of stability and accuracy. The diameter of the compression platen should be larger than the outer diameter of the specimens, due to which the diameter of 5mm was less than expected in this work. Meanwhile, the average value of the maximum radial force (F) was PP (98.35 cN)>PLA-1 (84.67 cN)>PGA (63.68 cN)>PLA-2 (39.24 cN)>PLA-3 (20.15 cN). The compression rate of 50% should be selected as the optimum parameter. In conclusion, this test method of monofilaments was successfully developed and has a potential application for the characterization of compression behaviors of ACE monofilaments for the human body.
