Designing, prototype making and evaluating a mechanical aid device for patient transfer between bed and stretcher

Introduction. The present study aimed at designing, prototype making and evaluating a new assistive device to improve patient transfer conditions. Methods. A new aid device for patient transfer was designed and its prototype was made. Comfort and perceived physical exertion of users and stability and applicability of the device were examined. The test subjects included 37 healthcare workers from a hospital with patient transfer experience. The data collection tools consisted of visual analog scales (VAS) and Borg's rating physical effort scale. The rapid entire body assessment (REBA) method was applied to evaluate working posture. Results. The results showed that in 70% of the wards, patient transfer was performed manually more than five times per shift. While using the newly designed device, the mean (SD) of the users' comfort, and the clients' comfort and safety, was measured as 8.59 (0.87), 8.46 (0.92) and 8.67 (0.71), respectively, as reported by VAS. The results revealed a significant reduction in the users' rating of perceived exertion (p
