The invention discloses a design method of a
waist pillow for
lying conservative treatment of a patient suffering from
lumbar disc herniation, and belongs to the field of
medical rehabilitation assistive devices. In order to solve the problems that an existing
waist pillow is difficult to adapt to individual
waist curvature difference and insufficient or excessive support exists, the method is based on ergonomics, the physiological bending forms of
sacrum, fifth
lumbar vertebra, fourth
lumbar vertebra and nearby waists are researched, and a
mathematical formula is constructed to design the curved surface of the contact surface of the waist pillow and the waists. The height and the bending degree of the waist pillow are adjusted through the parameter b, the bending degree of the waist pillow towards the head side and the bending degree of the waist pillow towards the foot side are adjusted through a, and accurate attachment of the waist pillow and the waist is achieved. The method adapts to
wood processing and plastic mold standardized production, a special waist pillow can be customized for a patient, products of different models can be produced in batches according to waist shape data of people,
intervertebral disc pressure is effectively reduced, the
treatment effect is improved, and the method has the advantages of customization accuracy and production efficiency.
