技术领域Technical Field
本实用新型属于医疗器械设备自动化控制领域，具体说是一种可远程控制与监测的智能翻身护理床控制系统。The utility model belongs to the field of automatic control of medical equipment, in particular to an intelligent turning nursing bed control system capable of remote control and monitoring.
背景技术Background Art
智能翻身护理床是一些生活无法自理以及残障、失能人士的理想护理设备，与一般的护理床相比，不但具备多种常见的姿态调节功能，还增加了翻身调节功能，同时还具备远程控制与状态监测，以及定时自动调节姿态等功能。既减少护理人员的体力负担，也降低了被护理者的意外风险。The intelligent turning nursing bed is an ideal nursing device for people who cannot take care of themselves, or who are disabled or incapacitated. Compared with ordinary nursing beds, it not only has a variety of common posture adjustment functions, but also has a turning adjustment function, as well as remote control and status monitoring, as well as timing automatic posture adjustment functions, etc. It not only reduces the physical burden of nursing staff, but also reduces the risk of accidents for the person being cared for.
目前国内外的电动护理床功能比较单一，常见的只能通过护理床上的手控器、对护理床姿态进行床旁手动控制，这就限制了电动护理床的使用场景，同时对于无法进行控制操作的失能使用者，在控制护理床时只能由护理人员在床旁边进行陪伴操作。因此设计一种可实现远程控制护理床姿态调节并进行实时状态监测，集中监控多个护理床的使用状态及使用者的身体状态，并根据使用者平时姿态调节习惯的数据收集及分析，定制定时自动姿态调节，对于减少护理人员工作量及丰富电动护理床的使用场景具有十分重要的意义。At present, the functions of electric nursing beds at home and abroad are relatively simple. Commonly, the posture of the nursing bed can only be manually controlled by the hand controller on the nursing bed, which limits the use scenarios of electric nursing beds. At the same time, for disabled users who cannot perform control operations, the nursing bed can only be controlled by nursing staff beside the bed. Therefore, a device that can realize remote control of nursing bed posture adjustment and real-time status monitoring, centrally monitor the use status of multiple nursing beds and the physical condition of users, and customize timed automatic posture adjustment based on data collection and analysis of users' usual posture adjustment habits is of great significance for reducing the workload of nursing staff and enriching the use scenarios of electric nursing beds.
