Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a Bed for Preventing Pressure Sore Having Lift,

More particularly, the present invention relates to a medical bed, and more particularly, to a lift apparatus for vertically moving up and down on both sides of a bed, lifting a pedestal from a lower side of a patient using a lift apparatus, The present invention relates to a bed for preventing a pressure ulcer which can be easily transferred to a foldable wheelchair or a transferring device for preventing a pressure ulcer or transferring a patient.

A pressure ulcer (bed ulcer) is a disease in which the skin of a patient lying on the bed for a long time is necrotized and inflammation occurs. This occurs when a part of the patient's body lying on the bed touches the surface of the bed for a long time and is constantly pressed. In this way, when a part of the body is pressed for a long time, the circulation of blood to the skin of the area is not smooth, and the air does not pass well, resulting in necrosis of the skin and a pressure ulcer.

Currently, a variety of bed sores prevention or prevention beds have been filed for patent, and it is known that a ventilation is smoothly provided with a net (Patent Laid-Open No. 10-2001-0001177), a flat plate and a steel plate constituting a top plate of a bed are alternately lifted (Japanese Patent Laid-Open No. 10-2003-0020162), which improves the circulation of air by spraying air to the bottom of the bed (Patent No. 10-0476513), and the like .

In the case of the lifting and lowering of the steel plate, the structure including the power system required for driving the steel plate is complicated. In particular, when the steel plate as the movable part is raised and lowered, interference occurs with the fixing part, .

In case of the air circulation type, when the patient can not maneuver at all, contact with the bed for a long time causes the air to be hardly supplied to the pressed body part, and the prevention effect of the pressure ulcer is reduced.

In addition, since the conventional bed for preventing bedsore is constituted by merely focusing on the function of lifting the patient from the bed, there is a problem in that a separate transfer device must be used in order to transfer the patient to another place.

Open Patent No. 10-2001-0001177 (2001.01.05) Registration No. 10-1043453 (June 15, 2011) Open Patent No. 10-2004-0017525 (Feb.
