Abstract: A pneumatic invalid lift comprises a wedge-shaped inflatable air bag for positioning on a seat surface, and a high volume, low pressure vane-type blower for supplying air to the air bag through a flexible hose connection. Air is discharged from the bag through a small-section outlet nozzle. A remote controlled switch is provided for enabling a person using the air bag to operate the motor whereby the bag is inflated when the motor is running and deflated by exhaust of air through the blower and discharge nozzle when the motor is switched off.
