An intelligent bed system based on action intention recognition and its application method

Abstract

The present invention is an intelligent bed system based on action intention recognition and its use method. The intelligent nursing bed system is based on the existing mechanical nursing bed, adding bed board partitions, pressure sensor modules, and controllers, and improving its functions. Through the pressure sensor module, the pressure change data of the user lying down is obtained in real time, and then the controller relies on the preset intention recognition algorithm to analyze and identify the bed surface pressure data when the user has the intention to get up and lie down, and transmit the action intention signal To the driver, control the booster device of the driver, make the electric push rod in the corresponding area expand and contract, drive the corresponding bed board to lift or tilt, realize the functions of bed board lifting and angle inclination, and automatically adjust the sleeping position of the bedridden person, which can relieve excessive pressure. Potential health hazards such as sores.

Description

technical field [0001] The invention relates to the field of intelligent beds, in particular to an intelligent bed system based on motion intention recognition and a method for using the same. Background technique [0002] As my country gradually enters an aging society, there are more and more people at high risk of pressure ulcers. Pressure ulcers not only cause great physical and psychological harm to patients, but also bring heavy burdens to families and society. The number of handicapped people caused by various disasters and diseases is also increasing year by year, and they have different degrees of loss of abilities, such as walking, vision, hands and language. No matter the traditional nursing bed is hand-operated or electric, it is limited to the conditions of human operation. [0003] In the development process of nursing beds, automation, safety, and comfort have become the index parameters of its development, and people are paying more and more attention to the...

Problems solved by technology

[0004] The intelligent pressure sore measurement and control turning bed researched by the Second Affiliated Hospital of Nantong University (Chen Chunmei, Wang Lihua, Gu Haiyan, etc. Development of intelligent measurement and control pressure sore turning bed. China Medical Equipment, 2012, 27(1)) is placed on the patient's pressure part Put a special constant temperature and pressure measuring water pad to obtain the pressure of the patient's local tissue, measure the pressure distribution of the human body on the nursing bed through the pressure sensor, and propose an alarm signal based on the pressure-time safe area curve to remind the medical staff to prevent the patient from developing pressure sores. However, the cost of the special constant temperature and pressure measurement water cushion is relatively high. In addition, in this study, only an alarm signal is sent out after the safety range is exceeded, and it cannot automatically assist the patient to turn over, because it is impossible to automatically control the patient's posture on the nursing bed without knowing the patient's posture. The nursing bed completes the turning action, so there are still some limitations
