Smart bed system based on motion intention recognition and using method thereof

Abstract

The invention relates to a smart bed system based on motion intention recognition and a using method thereof. The smart bed system is based on the existing mechanical nursing bed, a bed plate partition, a pressure sensor module and a controller are added, and the functions of the existing bed are improved. The pressure sensor module obtains the pressure change data of a user lying in real time, and then the controller recognizes an algorithm relying on the preset intention. The bed surface pressure data is analyzed and identified when the user has the rising and lying intention, an action intention signal is transmitted to a driver, a boosting device of the driver is controlled to enable an electric push rod in the corresponding area to stretch and drive a corresponding bed plate to be lifted or tilt, so that the function of bed plate lifting and angle tilting can be achieved. The sleeping position of the bedridden can be adjusted automatically to relieve the potential health risks ofsores caused by excessive pressure.

Description

Technical field [0001] The invention relates to the field of smart beds, in particular to a smart bed system based on action intention recognition and a use method thereof. Background technique [0002] As our country gradually enters an aging society, there are more and more people at high risk of pressure ulcers. Pressure ulcers not only cause huge physical and psychological harm to patients, but also bring a heavy burden to families and society. The number of people with disabilities caused by various disasters and diseases is increasing year by year, and they have varying degrees of loss of ability, such as walking, vision, hands-on, and language. Traditional nursing beds, whether hand-cranked or electric, are limited to human operation. [0003] In the development of nursing beds, automation, safety, and comfort have become the index parameters for their development. People are also paying more and more attention to them. They can drive the bed up and down or tilt a certain a...

[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
