TECHNICAL FIELD

[0001] The utility model relates to handrail technical field, concretely is intelligent handrail device that can adjust with mattress and have rotation function. BACKGROUND

[0002] The intelligent medical bed handrail is a medical bed accessory integrating modern technology, aiming to improve the convenience and safety of patient care. Its main functions include automatic adjustment of height, angle and direction to adapt to the needs of different patients, especially for the elderly and patients with difficulty in movement. Intelligent handrails are usually equipped with sensors to detect the posture and activity of patients and timely feedback abnormal conditions to help nursing staff provide more timely intervention. Some intelligent handrails also integrate remote control and voice control functions to further improve the convenience of operation. At the same time, the handrail design takes into account the comfort and ergonomics, making the patient more safe and comfortable during use.

[0003] When a patient with epilepsy or a child hits the bed handrail in an unconscious state, the impact force will be transmitted to the bed structure through the handrail. The size of this impact force is affected by several factors, including the mass of the impact object, the impact speed, and the duration of the impact. According to Newton's second law (F = ma), the impact force (F) is the product of mass (m) and acceleration (a). If the patient or child's activity is more violent, or the impact speed is faster, the impact force will increase. These impact forces are directly transmitted to the bed structure, which may cause the bed to lose balance or vibrate instantaneously, affecting the safety of the patient and the normal use of the bed. According to the principle of conservation of energy, the kinetic energy generated by the impact force will be converted into stress inside the bed. The bed structure may lose stability. When the impact force exceeds the designed load capacity of the bed, the bed may quickly deform or tilt, leading to instability. Even instability or tilting.

[0004] In view of this, we propose an intelligent handrail device that can adjust with the mattress and has a rotating function. INVENTION CONTENTS
