Description

  The present invention relates to a nursing bed auxiliary tool and a nursing bed using the same. Specifically, the bed guard of the care bed, the end-sitting aid when the care recipient is seated, and the care bed aid that can be used as a transfer aid when the care recipient is transferred to a wheelchair, etc. It was about the nursing bed.

  Many of the frail elderly who are hospitalized or occupying hospitals and nursing homes are not bedridden, requiring full care, but they can be affected by an accident, illness, old age, etc. There is a lot of time spent on the bed because of the decline. On the bed, the back of the bed is raised or a cushion is sandwiched between the back to make a backrest. It remains. Under such circumstances, the erection of the vertebral column, which is originally used when a person takes a standing position, causes disuse atrophy, and the muscular strength that holds the sitting position, standing position, etc., declines. It is necessary not only to take a sitting position, but particularly to take an edge sitting position.

  In the past, pillows and cushions were placed on the waist of frail elderly, etc., and they were placed in the end sitting position. If you just hit it, it would fall forward and you had to be assisted by an assistant. Therefore, hospitals and nursing care facilities where there are not enough nurses, caregivers, etc. cannot respond, and the posture is changed to maintain a sitting position for frail elderly people or from a sitting position to a standing position. Therefore, there was a problem that appropriate rehabilitation training could not be performed.

  On the other hand, a bed for assisting transfer to a portable toilet or the like has been proposed (see, for example, Patent Documents 1 to 3). These beds rotate a part of a nursing bed assist tool so that it is perpendicular to the side edge of the bed so that frail elderly people can use the portable toilet from the bed for excretion or rehabilitation training. It can be used as a handrail when transferring to a wheelchair or wheelchair. However, this bed rail can only be used as a handrail for transfer, so it cannot be used to allow frail elderly to take an end-sitting position without the assistance of an assistant, etc. There is no bed rail that can safely maintain the position of the end sitting position by itself and the bed using this.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a conceptual diagram showing the overall configuration of a nursing bed assisting tool 1 according to a first embodiment of the present invention. In FIG. 1, a connecting member 11 is a flat plate-like member for fixing the nursing bed assist tool 1 to a side end of a nursing bed (not shown), and is provided at both ends of the bottom surface of the connecting member 11. By fitting the substantially cylindrical projections 111a and 111b into attachment holes (not shown) provided on the upper surface of the side end of the nursing bed, the nursing bed assist tool 1 is placed on the side of the nursing bed. It can be fixed.

  A substantially circular columnar support 12a is erected on one end (on the right side in the drawing) of the upper surface of the connecting member 11, and a substantially circular beam 13a is formed on the upper end of the support 12a. It is fixed in a cantilever shape so as to be substantially perpendicular to. The column 12a is supported so as to be rotatable about a vertical axis (around the center axis of the column 12a) with respect to the connecting member 11, and operates in conjunction with the lock lever 14a provided at the upper end of the column 12a. The lock mechanism (not shown) is configured to be fixed at a predetermined or arbitrary rotation angle. By adopting such a configuration, the nursing bed assisting tool 1 rotates the beam-shaped body 13a around the vertical axis (around the central axis of the support column 12a), and positions the beam-shaped body 13a in at least three states. That is, a state that is substantially parallel to the side end of the bed on the column 12b side (the state shown in the figure), a state that is substantially perpendicular to the side end of the bed inside the bed (the back side in the figure), and the bed It is possible to displace the outer side (front side in the figure) to a state substantially perpendicular to the side edge of the bed and fix it in each state.

  Further, a substantially circular column 12b is erected on the other end (on the left side in the figure) of the upper surface of the connecting member 11, and two substantially circular beams are formed in the substantially central portion of the column 12b. The bodies 13b are fixed in a cantilever manner so as to be substantially parallel to each other and substantially perpendicular to the column 12b. The support column 12b is rotatably supported around the vertical axis (around the center axis of the support column 12b) with respect to the connecting member 11 in the same manner as the support column 12a, and a lock lever 14b provided at the upper end of the support column 12b and A lock mechanism (not shown) that operates in conjunction with this can be fixed at a predetermined or arbitrary rotation angle. By adopting such a configuration, the nursing bed assisting tool 1 rotates the beam-shaped body 13b around the vertical axis (around the center axis of the support column 12b), and positions the beam-shaped body 13b in at least three states.
