Patient lifts are medical devices used to safely transfer patients with limited mobility. They reduce the risk of injury to both patients and caregivers. There are manual lifts, which require physical effort, and powered lifts, which use electricity or batteries for easier operation. Key components include a lift sling for support, a lift arm and frame for movement, a base with wheels for mobility, and a control mechanism for operation. Patient lifts are essential in healthcare settings to improve safety and comfort during patient transfers.
