摘　　要：为了减轻医护人员的工作强度及交叉感染的风险,设计了一种针对咽拭子采样的纯扭转软体夹持器。该夹持器采用螺旋气腔结构并设有安全保护装置。设计了螺旋气腔结构形状和排布方式,基于Abaqus有限元分析软件,并结合正交试验法对气腔结构进行优化设计,选出最优腔型在100 kPa负压时,咽拭子在口腔中划过的弧长为13.88 mm,满足口腔尺寸和采样要求。In order to reduce the work strength of medical staff and the risk of cross-infection,a pure torsion software holder for pharynx swab sampling was designed.In the gripper design,the spiral air cavity structure is adopted,and the safety protection device is equipped.The structure shape and arrangement of the spiral air cavity are designed.Based on the Abaqus finite element analysis software and the orthogonal test method,the air cavity structure is optimized,and the optimal cavity type is selected.When the negative pressure is 100 kPa,the displacement of the pharynx swab in the mouth is 13.88 mm,which meets the oral cavity size and sampling requirements.
