Standing beds

Standing beds (also known as electric standing beds or assisted standing beds) are indispensable training devices in rehabilitation medicine and long-term care. They are widely used in neurological rehabilitation, orthopedic rehabilitation, geriatric care, and spinal cord injury rehabilitation. Standing beds use electric actuators to gradually raise the bed surface from a horizontal to an upright position, assisting patients who are bedridden for extended periods or who have lower limb dysfunction with standing exercises. The gradual transition from a supine to a standing position effectively promotes blood circulation in the lower limbs, prevents muscle atrophy and osteoporosis, improves respiratory and digestive functions, and reduces the incidence of pressure ulcers. For patients with hemiplegia following a stroke, spinal cord injury, or post-fracture surgery, standing training is a prerequisite and foundation for regaining the ability to walk.

Our electric linear actuator system is a precision drive component specifically designed for posture adjustment in standing beds. By receiving commands from the control system, the actuator precisely controls the angle and speed at which the bed surface is raised. Compared to traditional manual or pneumatic solutions, the electric linear actuator provides a smoother, more controllable, and safer standing training experience.

Key features and benefits

Smooth transitions to ensure patient safety and comfort

During the transition from a horizontal to an upright position on a standing bed, the patient's center of gravity and the distribution of forces on their body are constantly changing. Any jolts or swaying may cause the patient anxiety and fear, or even result in secondary injury. Our electric linear actuator provides constant-speed, jerk-free linear motion throughout the entire process—from a 0° horizontal position to an upright position of over 80°—ensuring a smooth, gradual, and controllable transition. Patients complete the transition from lying down to standing without even realizing it, significantly enhancing their sense of security and compliance.

Progressive angle control—tailored to the training requirements of different rehabilitation stages

Patients at different stages of rehabilitation exhibit significant variations in their tolerance for standing angles. In the early stages, patients' cardiovascular systems have been in a horizontal position for an extended period; sudden upright positioning can lead to a sharp drop in blood pressure (postural hypotension), while the bones and muscles of the lower limbs have not yet adapted to bearing weight. Training must therefore begin at a low angle of 30°, allowing the cardiovascular system to gradually adapt to the redistribution of blood flow in the upright position, while enabling the muscles and bones of the lower limbs to progressively regain their weight-bearing capacity.

Our linear actuators provide precise stroke control and stepless angle adjustment, enabling therapists to incrementally raise the bed surface from 30° to 80° in accordance with the patient's rehabilitation progress.

Multiple safety features safeguard every standing exercise session

As standing exercises involve significant changes to the patient's posture, safety is the top priority. Our electric linear actuators are equipped with multiple safety mechanisms:

● Soft start and stop: speed transitions smoothly at the start and end of operation to prevent inertial impact

● Overload protection: automatically stops in the event of overload to protect both the equipment and the patient

● Power-failure lock: the actuator automatically locks in the event of a sudden power cut, preventing the bed panel from dropping unexpectedly

High load capacity, effortlessly supporting the patient's weight

When the standing bed is in the upright position, the patient's entire body weight is transferred via the bed panel to the actuator system, generating significant thrust requirements and bending moments. Our electric actuators provide ample thrust reserve, effortlessly supporting the standing training needs of patients of varying weights. The actuators use a high-strength transmission structure, ensuring smooth and stable movement even under heavy loads at maximum tilt angles.

Built-in Hall sensors enable precise control for customers

Our actuators feature built-in Hall sensors that provide real-time feedback on stroke position and operational status via pulse signals. Customers' control systems can use this data to accurately monitor the bed panel's real-time angle, enabling intelligent functions such as angle memory, progressive training, and safety alerts. The real-time feedback from the Hall sensors provides a reliable positional reference for the precise control of every standing exercise.

Rehabilitation robots

Rehabilitation robots represent a cutting-edge field at the intersection of rehabilitation medicine and robotics technology. They are widely applied in neurological rehabilitation (stroke, spinal cord injury), orthopedic rehabilitation (post-joint replacement, sports injuries), geriatric rehabilitation, and pediatric rehabilitation. Through precise mechanical drive and intelligent control, rehabilitation robots assist patients in performing repetitive, task-oriented rehabilitation exercises, effectively restoring limb function. Unlike traditional one-to-one manual rehabilitation training, rehabilitation robots can deliver high-intensity, highly consistent, and quantifiable training programs, significantly enhancing the efficiency and effectiveness of rehabilitation.

Rehabilitation robots come in various forms—ranging from lower-limb exoskeletons and upper-limb rehabilitation robots to finger rehabilitation robots and ankle rehabilitation robots. Regardless of the form, electric linear actuators serve as the key executive components for realizing core functions such as joint actuation, posture adjustment, and load regulation. The actuators are supplied as individual components featuring built-in Hall sensors and are integrated into the customer's control system.

Our electric linear actuator system is a precision drive component specifically designed for the various movements performed by rehabilitation robots. The actuator converts the rotational motion of the motor into precise linear motion, driving the robot's joints to perform rehabilitation movements such as flexion, extension, and rotation. Its high precision, low noise, and long service life make it an ideal choice for rehabilitation robot drive solutions.
