It is a kind of equipment that works in hospitals, sanatoriums and similar institutions. It can be arranged on beds or stretchers at a certain height to work for patients who are anesthetized or unable to work automatically. It can rotate 90 degrees in a certain direction to improve patients'physique. It is common in these buildings to drag him from stretcher to bed, or from bed to bed, and to take other similar necessary steps.To this end, he used a special long washcloth, the width of which is equivalent to the trunk of an ordinary patient. It consists of a lower chassis and defines a pair of wheeled corridors, from which a pair of continuous longitudinal corridors are designed. They are interconnected during the long journey, and a pair of upper corridors are supported at the top. These corridors are projected on Valladiso H. Forward horizontally, higher than the height of any conventional bed or stretcher； in these top lengths, the first roller tractor extends horizontally.In the vertical slope mentioned above, the second tractor roller extends horizontally, and both rollers are connected with the same decompression drive motorcycle； there is a third roller between the two tractors, which is also transverse and equal in length, and is installed in the state of free rotation. Arch-criminal. All wheels on the chassis are omnipotent, and there are brakes on the back seat. Two tractors are connected to the motorcycle by chain and gear mechanism. The roller of the previous tractor is installed on the last wheel, adjacent to the free end of the previous wheel, and the next wheel is the tractor.It is mounted at an intermediate height on the rear vertical slope. The free rotation knee joint is installed at the joint between the last and the next voyage.Es un aparato concebido para actuar en hospitales, sanatorios y similares, apto para disponerse a cierta altura sobre una cama o camilla con el objeto de trabajar sobre un paciente anestesiado o que no puede moverse por s
