The article discusses a groundbreaking innovation in needle design that addresses the widespread issue of "needle phobia," affecting over 10% of the global population. The conventional cylindrical needle has been reimagined into a conical shape, inspired by the painless proboscis of a mosquito. This new design, introduced by Masayuki Okano and Terumo Corporation, allows for a painless injection experience by facilitating a vortex flow of medicine, resulting in fast and effective administration. The Nanopass 33 needle, launched in 2005, represents a significant advancement in the market, combining a slim diameter of just 0.2 mm with a novel production process that allows for mass manufacturing. This innovation not only enhances patient comfort but also promotes better healthcare access for those with needle phobia. The success of this design signals a shift in manufacturing toward geometrical and mathematical innovations, potentially opening new avenues in various sectors. Ultimately, the painless needle exemplifies how nature-inspired designs can lead to significant improvements in medical technology and patient care.
本文讨论了一项突破性的针头设计创新，旨在解决影响全球超过10%人群的“针头恐惧症”问题。传统的圆柱形针头被重新设计为锥形，灵感来自于蚊子无痛的喙。这种新设计由冈野雅之和德鲁摩公司推出，通过促进药物的涡流流动，使注射过程无痛且快速有效。2005年推出的Nanopass 33针头在市场上代表了一项重要进展，结合了仅0.2毫米的细径和一种新颖的生产工艺，实现了大规模生产。这项创新不仅增强了患者的舒适度，还促进了针头恐惧症患者获得更好的医疗服务。这种设计的成功标志着制造业向几何和数学创新的转变，可能在多个领域开辟新的途径。无痛针头展示了自然启发设计如何带来医疗技术和患者护理的显著改善。
