Development of a stairlift for the elderly patients in the hospitals

Abstract

The objective of the study is to develop a stairlift as a means of transportation in the hospitals for the mobility of elderly patients and elderly visitors when going up and downstairs in the hospital. Care and service activities in hospitals are mostly done on the 2nd floor or the 3rd floor of the hospital. The mobility of the patients and the hospital visitors to go up and down to the 2nd or 3rd floor of the hospital mostly uses the lifts elevator. Sometimes hospitals have limitations in providing lifts elevators because they are expensive and require a large space. To solve this problem, a stairlift can be a solution to the mobility of the patients up and down from the 2nd floor or 3rd floor of the hospital, especially for elderly patients. A stairlift is a chair that moves up and down the stairs using a rail or track. The methodology used in this study is a literature study, design, prototype making, strength test of the guide rails, speed test of the stairlift, and REBA analysis. Stress analysis of the stairlift guide rails is slightly above 100 MPa, but still, below the allowable stress for the material, it is 160 MPa. The deflection analysis of guide rails meets ASME A18.1 standards, which is below 6 mm. The stairlift speed test meets ASME A18.1 standards, which is below 0.2 m/s. REBA analysis shows the ergonomic value of the stairlift passengers on action level 1 with a score of 3 (Low-risk level).
