Description

Technical Field

[0001] This invention relates to the field of smart beds, and in particular to a smart nursing bed and its control system. Background Technology

[0002] With the aging population and the intelligent upgrading of the healthcare industry, intelligent nursing beds, as core equipment for the daily care of long-term bedridden patients and people with limited mobility, directly impact the quality of care and the quality of life of users due to their practicality, safety, and intelligence. Currently, most intelligent nursing beds on the market possess basic functions such as posture adjustment and safety protection, but they still have many shortcomings in areas such as multi-module collaborative operation, accuracy of health monitoring, ease of operation, and environmental adaptability, making it difficult to fully meet diverse nursing needs. In particular, existing technologies have not yet formed a complete solution for core pain points such as pressure protection, health risk warning, and convenient operation for long-term bedridden patients. There is an urgent need for an integrated, intelligent, and user-friendly intelligent nursing bed and control system to fill this market gap.

[0003] The current field of intelligent nursing beds suffers from numerous technical deficiencies, making it difficult to fully meet diverse nursing needs: Posture adjustment is mostly based on overall lifting or simple zone adjustment, with poor correlation between support areas, lack of angle feedback and intelligent adaptation algorithms, and an inability to automatically optimize support posture based on pressure distribution. This results in low adjustment precision and a high risk of pressure sores. Physiological parameter monitoring largely relies on contact devices, which are cumbersome to wear. Non-contact products suffer from limitations such as single parameters and insufficient accuracy. Health warnings are triggered based on fixed thresholds, leading to delayed responses and a lack of predictive capabilities. In terms of safety, bed rail lifting control methods are outdated, fall warning functions are limited, and the risk of falling from the bed cannot be accurately identified. Environmental adaptability is poor, and most beds lack integrated local temperature and humidity control and intelligent lighting automatic adjustment functions, resulting in insufficient comfort. Control methods are primarily manual, and even some products supporting remote or voice control suffer from single commands, inaccurate recognition, and a lack of stable remote collaboration functions, preventing caregivers from real-time remote monitoring. Furthermore, many functional modules operate independently, lacking a unified main control unit and collaborative logic, hindering effective data exchange and resulting in a low overall level of integration and intelligence.

[0004] Therefore, there is a need to provide an intelligent nursing bed and control system to solve the above problems. Summary of the Invention

Through a flexible pressure sensor array laid inside the mattress, and heart rate and respiratory monitoring sensors and body movement sensors integrated into the headboard, it achieves real-time collection of multi-dimensional health data such as heart rate, respiratory rate, body movement, and pressure distribution. The monitoring accuracy can reach heart rate ±2 beats / minute and respiratory rate ±1 beat / minute. No additional equipment is required for the user, improving user comfort. The main control unit comprehensively analyzes the multi-parameter data through an intelligent evaluation algorithm, which can accurately determine the user's health status. When health risks such as abnormal heart rate, rapid breathing, or frequent body movement occur, an audible and visual warning is immediately triggered, and warning information is pushed to multiple devices such as the nursing station monitoring terminal and smartphones, enabling early detection and intervention of health risks and solving the problems of delayed warnings and low accuracy in existing technologies.
