Bed actuators are devices used to adjust beds in hospitals and homes. They can be powered by electric motors, hydraulic or pneumatic systems. Hospitals use multiple sets of actuators to adjust beds for patient comfort and transport. Personal beds are simpler and cheaper, and can be used for tasks like lifting a person into a sitting position. Electric motors are the most common power source, but hydraulic and pneumatic systems are necessary for heavier patients and beds. They are more expensive and require more maintenance.
A bed actuator is a device used to raise and lower beds or to adjust parts of the bed. These actuators are most often used by hospitals, so patients can lift themselves easily. The power source that operates a bed actuator can be an electric motor or a hydraulic or pneumatic system; motors are simpler, although hydraulic and pneumatic systems are best for heavier patients and more frequent use.
The primary users of a bed actuator are hospitals and other healthcare settings. These facilities use beds with actuators to easily position patients for comfort or to adjust their bodies for easy transport by medical staff. Hospital beds often use multiple sets of actuators to adjust the bed to different positions.
Personal beds using a bed actuator are typically much less complex than hospital versions and much cheaper. They can be used for simple tasks such as lifting a person into a sitting position or elevating a person’s legs and feet for more comfort. Elderly or disabled people can use actuator sets to lower and raise the entire bed so that they can get in and out of bed more easily.
Most commonly, a bed actuator uses one or more small electric motors for power. It is not uncommon for a bed actuator to be rated for more than 600 pounds (272 kilograms) for a single bed. The electric motor usually turns an actuator arm’s screws through a bolt, causing the arm to expand and push up the payload. Instead, the motor causes the screws to unwind and the bed height to decrease. The motorized actuator also prevents damage to the bed or injury to the occupant in the event of a failure; if a failure occurs, the bed will remain as is.
Some forms of bed actuator use hydraulic and pneumatic systems. These are quite rare, but are necessary when lifting heavier patients and when paired with heavy beds. They work on the concept of using controlled compressed air or liquids to lift heavier loads that could strain or damage the electric motors and rotating parts of a mechanical actuator. This type of bed actuator is also a little more expensive and requires more effort to maintain and lasts about as long as the least expensive electric motor actuator.
