Abstract

Objective To develop a medical wheelchair scale tailored for clinical settings, addressing the challenges of traditional scale measurements for patients with mobility impairments, bedridden individuals, and postoperative wheelchair users, thereby enhancing the convenience, accuracy, and safety of clinical weight assessment.
Methods Based on clinical application pain points, a medical wheelchair scale was designed to integrate wheelchair adaptation, precise weighing, safety protection, and user-friendly operation. The structure comprises a weighing load-bearing module, a wheelchair positioning and fixation module, and a data display and transmission module, enabling direct wheelchair measurement through structural optimization.
Results This medical wheelchair scale allows for non-transfer weighing of wheelchair-bound patients, with measurement errors controlled within clinically acceptable limits. The positioning and fixation structure ensures safety during measurement, while the operational workflow aligns with the clinical habits of healthcare professionals.
Conclusion   The structural design of the medical wheelchair scale meets practical clinical needs. It holds significant application value in departments requiring wheelchair-based weight measurement, such as hemodialysis rooms, wards, or physical examination centers. This solution improves clinical weight assessment efficiency, reduces the workload of healthcare personnel, and ensures patient safety during medical visits.
