病床改良手柄让患者活动自如

IPL利用全新的设计方式,大大削减了医院病床患者辅助手柄所需的部件数目。

在1985年至2006年期间,美国FDA共收到约691份因医院病床系统引起的压伤报告——其中413例死亡。患者常因陷入病床护栏、床垫或床板之间或周围的空隙而造成被困事故,这是老年患者(特别是身体虚弱,无法控制身体动作或神志不清的患者)面临的最严重威胁。

鉴于上述被困事故,FDA于2006年发布了旨在减少被困事故的医院病床系统尺寸和评估指南。制定新指南的目的在于提供一种更安全、行动更自如的环境,以提高患者的生活质量,增强患者的自主性,同时提升护理者的安全。为此,一家面向急性后期照护市场的病床生产公司——Joerns Healthcare(维斯康星州Stevens Point;www.joerns.com)开始重新设计其Deluxe辅助病床手柄,以达到上述指南的要求,并期望通过减小风险改善患者护理。该公司与注塑产品制造商IPL Inc.(加拿大魁北克,Saint-Damien;www.ipl-plastics.com)合作完成了新产品的设计。

在设计过程中,IPL的技术销售人员和工程团队在有限元分析、快速原型设计及完整产品开发等方面提供了有力的支持和丰富的理论知识。 例如,手柄的最初设计构思是在焊接好的铁框上用螺丝将两块塑料壳固定在一起。 但IPL提出了一个更先进的设计理念,具体体现为三种做法。

首先,服务供应商采用嵌入式成型方法置入一根重要的铁管,使得客户可将这款重新设计的手柄用于现有的Joerns病床上(包括 EasyCare 5、7和9;UltraCare 700-系列;以及UltraCare XT型号)。然后,采用气辅技术在铁管上使用塑料进行二次成型,形成无缝式辅助设计。最后,IPL再次进行二次成型,在重要区段加盖一层更软的材料,以改善患者的舒适度,同时确保抓握牢固。

“这三种技术以独特的方式合而为一,形成了这款更牢固的患者辅助手柄,且手感更柔软、更舒适,”Joerns Healthcare公司工程总监David Genske说道。“Joerns Healthcare公司通过将部件数从37减少到11,最大程度减少了装配、库存管理、检修等工作及其成本,制造出了一种适用于长期护理市场的安全且符合人类工程学的辅助手柄。”
