Аnalysis of modern technical devices for improving working conditions in rehabilitation centers for people with disabilities

Abstract. The article provides an overview of the design features of modern technical devices used to improve working conditions in rehabilitation centers for people with disabilities. The primary focus is on the analysis of ceiling lifts, which are a key element in ensuring the mobility of patients with limited physical abilities. The design features of ceiling lifts are examined, including their modular system, ceiling mounting, control mechanisms, and safety features. The article also covers other rehabilitation devices used in conjunction with ceiling lifts, emphasizing their functionality, ergonomics, and reliability. The advantages of implementing such systems for optimizing the working conditions of medical personnel and improving the quality of patient care are described. Problem. The lack of domestic developments and manufacturers of such rehabilitation equipment is a major obstacle to providing centers with necessary devices. Most high-quality ceiling lifts and other assistive systems are imported from abroad. This increases the costs of purchasing and maintaining the equipment, making it inaccessible for many rehabilitation centers and hospitals, especially in remote regions of the country. Goal The purpose of this work is an analytical review of the designs of ceiling lifts from leading manufacturers to determine the necessary steps for design, calculation, selection of required components, and production of this type of equipment by domestic manufacturers. Methodology. To address the design of a ceiling lift, we will first analyze scientific papers, patents, and technical documentation to understand existing designs and their advantages and disadvantages. Next, we will employ computer modeling to simulate the lift's operation, identifying potential flaws while ensuring safety and efficiency. Computational and analytical methods will aid in selecting materials and calculating critical parameters, including strength and load on the ceiling mounts. Finally, experimental studies will test the equipment in real-world conditions, verifying its reliability and functionality, leading to the development of a ceiling lift that meets all effectiveness, reliability, and safety requirements. Results. In the course of this work, an analytical review of the designs of ceiling lifts from leading global manufacturers was conducted, allowing for the identification of key technological solutions necessary for effective design and production of this equipment in Ukraine. To achieve high quality and competitiveness of the product, it is important to properly define the stages of the design process, which include: determining the functional requirements (load capacity, range of motion, ergonomic and safety requirements); developing the design and kinematic scheme; selecting materials; creating a control system with remote control capabilities that ensures speed regulation during lifting and emergency stopping; designing mechanisms for safe operation; and conducting market research to localize production and assess economic efficiency under limited funding conditions.
