A new proposal of tailored bioinstrumentation using rapid prototyping and three-dimensional CAD--first trial to develop individually designed cuff-units for continuous blood pressure measurement.

The concept of tailored bioinstrumentation using rapid prototyping and three-dimensional CAD (3D-CAD) was proposed. This concept is to make individually designed and fabricated sensor unit to attach human body. Within the proposed concept, cuff-units for continuous blood pressure measurement were individually designed using 3D-CAD and fabricated automatically. As the result, blood pressure wave forms can be obtained using the finally developed cuff units. Using rapid prototyping device, the design and fabrication process were accelerated without any artisan-like high skilled persons.
