A patient transfer trolley of the type which is used to transfer patient from a hospital bed to another location such as an operating theatre or an ambulance or a treatment room. The invention is concerned with a type of trolley which is on wheels and has an endless belt driven by rollers for transferring the patient. The invention provides such a transfer trolley which operates with the minimum inconvenience to the patient and the minimum apparent motion as far as the patient is concerned. The trolley has one or more driven wheels (31) and is so arranged that as the endless belt (23) is moved to move the patient, the driven wheels (31) are rotated simultaneously so as to move the trolley at substantially the same speed as the endless belt is moving but in the opposite direction. Thus the patient effectively remains stationary because the movement of the endless belt is exactly compensated for by the movement of the trolley as a whole and the patient is gently moved onto the bed or on the trolley according to the direction of movement of the endless belt. The driven wheel or wheels of the trolley are completely separate from the wheels on which the trolley is normally moved. The height of the endless belt is adjustable. |
