Description

  The present invention relates to a fall prevention device attached to a bed, and more particularly to a block-like fall prevention device having a height lower than that of a side fence.

  In general, a nursing bed used in a hospital or the like is provided with a fence (hereinafter referred to as a side rail) formed of metal or the like on both sides in order to prevent a user from falling from the bed. However, since such a conventional fall prevention device is provided up to a position higher than the user's body, there is a problem that the user is given a feeling of pressure and only the fall prevention of the user is considered.

  Therefore, a fall prevention device (hereinafter referred to as a side support) that is a block-shaped soft pad in which a core material such as polyester fiber is covered with a surface material has been proposed (see, for example, Patent Documents 1 to 7). This side support has a lower height than conventional fall prevention devices such as side rails, and has a minimum height that can support it so that it does not fall when the user rolls over. Fall can be prevented without giving a feeling. In addition, this side support is usually attached to the side frame or bottom of the bed, but the side surface is arranged so as to contact the side surface parallel to the longitudinal direction of the mattress, thereby preventing the mattress from shifting due to the user turning over. can do.

JP 2002-200123 A (page 2-3, FIG. 1-2) JP 2002-355148 A (page 2-3, FIG. 1-2) JP 2003-61783 A (page 3-6, FIG. 5-10) JP 2003-62018 (page 3-4, FIG. 3) JP 2003-33255 A (page 3-4, FIG. 1-8) JP 2003-38302 A (page 3-5, FIG. 1-10) JP 2003-52766 A (page 3-5, FIG. 1-12)

  However, the conventional techniques described above have the following problems. Since the side support has a low height, it is assumed that a user sits on the side support. Therefore, in order to ensure the rigidity of the frame, the conventional side support is made up of a strut member formed of a steel pipe or the like and a frame member formed integrally with the strut member, and these are, for example, foamed. The core material is covered with a core material such as a porous urethane resin or polyester fiber, and the outer surface is covered with the core material. Thus, since the conventional side support has a complicated structure, there is a problem that the cost is high.

  In addition, since the conventional side support is integrated with the outer material and the core material, it can not be washed and replaced even if the outer material becomes dirty or damaged, and it can be used repeatedly like rental There is also a problem of being unsuitable. Further, the conventional side support cannot cope with mattresses having different thicknesses, and there is a problem that mattresses to be matched are limited.
