Description

MEDICAL BED {MEDICAL BED}

TECHNICAL FIELD The present invention relates to a medical bed, and more particularly, to an invention relating to a medical bed adapted for a patient.

Generally, a fixed bed in which the shape and height of the bed is fixed is mainly used. However, even in the case of such a fixed bed, a bed used in a hospital or the like can be deformed into a form in which a part of the body such as a head, a leg, and a waist is inclined up and down in consideration of the condition of the patient.

The bed used for a patient having an inconvenient mobility has a structure in which the backrest of the patient is angled upwardly, thereby providing convenience in use. In addition, the mattress located in the leg of the patient is raised by manual operation or an electric driving force As shown in FIG.

Therefore, the patient who is inconvenienced can raise the one side of the mattress so as to watch TV, read and rest, and the angle adjustment structure of the mattress is made in accordance with the ascending and descending of the screw shaft by the rotation of the driving motor, And the operation time of the drive motor is controlled so that the angle can be adjusted to a desired angle and used conveniently.

In addition, although one side of the lower portion of the patient bed as described above is configured to be able to adjust the angle by manual operation as well as the angle by the driving motor, in recent years, due to the inconvenience due to manual operation, It is common to adopt a bed having an automatic angle adjusting structure.

However, in the case of such automatic operation and manual operation patient bed, the operation is performed uniformly without consideration of the patient's height, so that the form or length of the bed folded in the patient's body can not but be adjusted.
