韓han國guo科ke學xue技ji術shu院yuan研yan究jiu團tuan隊dui開kai發fa了le一yi種zhong由you镓jia製zhi成cheng的de針zhen，這zhe種zhong針zhen的de熔rong點dian高gao於yu室shi溫wen但dan低di於yu體ti溫wen，當dang針zhen進jin入ru體ti內nei時shi會hui變bian軟ruan及ji有you彈dan性xing
，可ke減jian少shao注zhu射she過guo程cheng中zhong的de炎yan症zheng和he損sun傷shang
，同tong時shi還hai可ke降jiang低di意yi外wai刺ci傷shang的de風feng險xian。研yan究jiu成cheng果guo最zui新xin發fa表biao在zai《自然·生物醫學工程》上。

針zhen頭tou和he塑su料liao導dao管guan在zai注zhu射she時shi經jing常chang引yin起qi炎yan症zheng和he並bing發fa症zheng，部bu分fen原yuan因yin是shi它ta們men不bu像xiang身shen體ti的de軟ruan組zu織zhi和he靜jing脈mai那na麼me靈ling活huo。如ru果guo醫yi療liao人ren員yuan在zai使shi用yong後hou不bu小xiao心xin被bei針zhen刺ci傷shang
，用yong過guo的de針zhen頭tou也ye有you傳chuan播bo疾ji病bing的de風feng險xian。

研yan究jiu團tuan隊dui此ci次ci在zai活huo體ti小xiao鼠shu身shen上shang測ce試shi了le镓jia針zhen，並bing測ce量liang了le與yu不bu鏽xiu鋼gang針zhen和he商shang業ye塑su料liao導dao管guan相xiang比bi的de組zu織zhi損sun傷shang和he炎yan症zheng。他ta們men發fa現xian，柔rou性xing針zhen引yin起qi的de炎yan症zheng比bi鋼gang針zhen少shao，而er炎yan症zheng程cheng度du與yu塑su料liao導dao管guan相xiang當dang。他ta們men還hai在zai針zhen上shang添tian加jia了le溫wen度du和he液ye體ti傳chuan感gan器qi，並bing表biao明ming它ta可ke用yong於yu測ce量liang小xiao鼠shu和he豬zhu組zu織zhi中zhong的de體ti溫wen和he注zhu射she過guo程cheng中zhong的de意yi外wai藥yao物wu泄xie漏lou。
