A mechanical lift, often called a patient lift, is a specialized device designed to safely raise and move individuals with limited mobility. This equipment primarily facilitates transfers between surfaces, such as a bed, wheelchair, or commode, for those who cannot bear their own weight. Using a mechanical lift drastically reduces the physical strain and risk of injury for caregivers. Correct application also minimizes the risk of falls and injury to the patient, preserving their comfort during necessary transfers. Proper training is required for all operators to ensure the device is used effectively and safely.
Pre-Lift Assessment and Preparation
Before any transfer, thoroughly assess the environment and equipment. Clear the immediate area around both the starting and receiving surfaces of obstacles like rugs, wires, or furniture that could impede the lift’s movement. Confirm the receiving surface, whether a chair or a bed, is prepared, with wheel locks engaged and removable components moved out of the transfer path.
The mechanical lift requires a mandatory pre-use check. Verify the integrity of the lift frame and wheels, ensure the wheel locks function, and confirm the battery has sufficient charge for electric models. Crucially, verify that the patient’s weight does not exceed the lift’s or the sling’s maximum safe working load (SWL). Communicate with the patient to explain the process, assess their tolerance for movement, and determine their capacity to assist.
Safe Application of the Sling
Correct sling placement is vital to prevent slippage or discomfort during the lift. When the patient is lying down, gently roll them onto their side using a logrolling technique to maintain spinal alignment. This allows the caregiver to tuck half of the folded sling smoothly underneath the patient’s back, aligning the center with the spine.
Roll the patient back onto the sling, then roll them to the opposite side to pull the remaining material flat. The sling must be centered beneath the patient, extending from the head/shoulder area down to just below the buttocks, based on the sling type. For divided leg slings, position the straps individually under each thigh, ensuring they are not twisted. Cross the straps over each other between the patient’s legs to create a secure, bucket-like seat that prevents sliding during the lift.
Operating the Lifting Mechanism
After positioning the sling, securely attach the straps to the spreader bar or cradle. Use the shortest loop length that achieves the desired seated or reclined angle. For stability, spread the base legs of the mobile lift to their widest position before initiating upward movement. This wider stance increases stability by lowering the center of gravity.
Lift the patient slowly and smoothly using the control pendant or hydraulic pump, ensuring the straps become taut without sudden jerks. Once the patient is raised just clear of the surface, pause to double-check all sling connections and assess the patient’s comfort. The operator must gently guide the patient’s body to maintain balance and prevent contact with the mast. Operators of electric lifts must know the location and function of the emergency stop button and the manual descent lever for controlled lowering during a malfunction.
Concluding the Transfer and Securing the Patient
Maneuver the suspended patient carefully toward the receiving surface, keeping the movement slow and the base open for maximum stability. Guide the patient directly over the center of the chair or bed. Initiate the lowering process with the same smooth, controlled motion used during the ascent. Lower the patient until their full weight is supported by the new surface, ensuring they are positioned comfortably against the backrest or headboard.
Once the patient is safely seated or lying down, release the tension on the sling straps and detach them from the spreader bar. If the sling is not intended to remain, remove it carefully, often requiring a slight forward lean or a brief roll. Perform a comprehensive safety check, ensuring the patient is stable, comfortable, and has access to their call light. Move the lift away, close the base legs, and plug in electric models for charging.
