一般如癱瘓、植物人、中風、脊椎損傷、腦部病變等須長期臥床的病患,必須定時翻身並加以拍打,避免產生壓瘡;由於長期臥床的病人人數逐年增加,但是醫護及照料人員卻無法隨之成長,而定時翻身的照護更需要極大的人力及時間。目前一般使用的病床設計上並不具備側翻功能,因此,期望藉由具側翻功能之多功能病床的研發,有效降低照護人員的人力與節省翻身拍背的時間,使得癱瘓與長期臥床的病人獲得更妥善的照顧。 本研究先針對既有的翻身裝置相關文獻加以蒐集、分類與分析,了解其設計重點、作動原理與優缺點。為了增加側翻病床的實用性,因此透過品質機能展開的應用,以作為訂定設計規範的參考,並篩選出病床設計的瓶頸技術。其次,本研究提出一符合規範的新型設計,且採用創造性機構設計流程,獲得更多可行機構之圖集。最後,對各機構進行運動分析,並利用電腦分析軟體ADAMS,將機構之各尺寸最佳化,驗證與模擬各機構之可行性;最後再根據模擬與分析的結果,挑選出最佳的設計。
Many patients, who are resident with persistent vegetative state (PVS), paraplegia, stroke and spinal cord injure (SCI), need to lie on sickbed chronically and must be turned their bodies regularly to prevent bedsore. While the number of these patients has been increasing annually, there are insufficient nurses to take care of them. The movement of turning and tipping a patient’s body regularly requires a lot of time and manpower. The current sickbed design, however, does not provide such function. Therefore, it is the aim of this research to develop a multi-function sickbed that has the capability of turning patient’s body over, and to reduce the time and manpower required on such medical care. Moreover, it could help these patients get better medical care. Firstly, the information of current multi-function sickbeds had been collected, categorized and analyzed to understand their designing criteria, motions, merits and defects. In order to increase the applicability of the new multi-function sickbed, we apply the technique of Quality Function Development (QFD) to set the requirements and to screen out the bottleneck technique for the design of such sickbed. Then, a new design that satisfies the requirements is presented. By applying the creative mechanism design methodology, we obtain additional mechanism graphs of potential design. The kinematic analysis of this new design is presented. The optimization has been done by ADAMS software to obtain the optimized size of its members. Through the simulation in ADAMS, the feasibility of the new design has been confirmed.
