Abstract

<P>PROBLEM TO BE SOLVED: To provide a simple, lightweight and inexpensive bed with less noise capable of preventing a bedsore and assisting turning concerning an aged person or sick person having difficulty in turning a body. <P>SOLUTION: Several bag shape belts enclosing a core material 8 in the center part are disposed over the bed in the same longitudinal direction. One ends of the belts are fixed to a frame on a floor surface in the rear (leg side) part of the bed and the other ends are disposed at a sleeve which is put through a frame on a floor surface in the front (head side) of the bed. The belts are partially wound right-handed and partially wound left-handed around a belt winding roller 6 which is arranged in the lower part of the sleeve so as to be fixed. When the belt winding roller 6 is rotated right-handed or left-handed, the two kinds of belts wound in the opposite rotary directions are simultaneously made to be in mutually opposite tension and loose states. When the belts are alternately arranged by several belts, the bed is used for preventing the bedsore. When the belts are divided with a center as a boundary so as to arrange only the right-handed belts at one side and to arrange only the left-handed belts at the other side, the bed is used for assisting the turning. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention relates to a bed for preventing bedsores and for turning over.

It is said that bed slip occurs at the time of pressure x compression time, and in order to protect elderly people and sick people who can not turn over freely from bed slip, roughly divide the bed floor into several parts, The air mat is divided into several independently sealed compartments, air is injected into these compartments, and the air pressure is divided into compartments. Methods have been developed to change and adjust the. Japanese Patent Laid-Open No. 2003-654 corresponds to the former example, and Japanese Patent Laid-Open No. 11-33062 corresponds to the latter example. Japanese Patent Laid-Open No. 2002-667 discloses an apparatus that looks similar to the present invention using a belt as a floor surface. In addition, an example of a device that has been developed in order to reduce the heavy labor of a caregiver when wiping the body of a non-caregiver from the left and right side and wiping the body or changing sheets is disclosed in Japanese Patent Laid-Open No. 5-317366. It is.

Problems to be solved by the invention

The above-mentioned Japanese Patent Application Laid-Open No. 2003-654 has a complicated structure, a lot of troubles and breakage points, high cost and weight.

The above-mentioned JP-A-11-33062 tends to be deformed so as to match the shape of a lying human body, and although the strength of the compression is reduced, the breathability is lacking and it is steamed. In addition, it takes time to adjust the air, and the accompanying sound is loud and annoying.

The above-mentioned JP-A-2002-667 is divided into a fixed belt and a movable belt, and only the height of the movable belt is adjusted. When the fixed belt supports a cared person, the belt hangs down in a U shape. The body of the non-caregiver who lies down because of the condition is tightened from the left and right and feels cramped. Further, when the movable belt supports the care recipient, the belt is almost horizontal. The unpleasant sensation resulting from the change in the floor surface is great, especially when the cared person is sleeping, and awakens and disturbs deep sleep. In addition, this is also complicated in structure and has many troubles and breakage points, resulting in high costs and weight.

In Japanese Patent Laid-Open No. 5-317366, the floor of the bed is divided in half from the center in the longitudinal direction, and the half of the cared person is tilted inward by lifting the outside of the floor without moving the center. At this time, the cared person's body often slides sideways, and the inclined floor surface itself remains in close contact with the cared person's body, May interfere with nursing care.

Means for solving the problem

In order to solve the above-mentioned problems, the present invention extends a plurality of bag-shaped bands enclosing a core material in the central portion in one longitudinal (longitudinal) direction of the bed, and one end of the belt is located behind the bed (foot). The other end is hung on a sleeve passed through the floor frame in front of the bed (bedside), and a part of it is wound clockwise on the belt take-up roller installed below the sleeve. In addition, a part of the belt is wound around and fixed to the left, and the belt winding roller is rotated clockwise or counterclockwise so that the two belts wound in the opposite direction of rotation are simultaneously opposed to tension and relaxation. When the belts are arranged alternately several times, it becomes a bed slip prevention bed, the belt is divided into right and left with the center as a boundary, only the right-handed belt on one side and the other on the other side. If you have arranged only the left wrapping belt, you can turn over The head.

The invention's effect

The present invention can simultaneously switch the two types of belts in a state where tension and relaxation are opposite to each other in one operation at the same time, and as a bed slip prevention bed, the change in floor shape before and after switching between the two types of belts is In addition, the caregiver is not disturbed to sleep, the caregiver's body is regularly released from the pressure, fresh air can be taken in, and bedsores can be prevented. In addition, as a support bed for changing the arrangement of the band, the caregiver can turn over sideways without slipping at the level difference caused by the switching, and the floor of the band always kept horizontal. As a result, care can be facilitated, and caregivers' heavy labor can be reduced. In addition, since the structure is simple and lightweight, the cost can be reduced.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a side view of a bed slip prevention bed. Several bands 2 and 3 wrapping the core material 8 in one longitudinal (longitudinal) direction of the bed main body 1 are bridged, and one end of each band is located behind the floor (leg) of the bed main body 1 in the vertical (longitudinal) direction. The belt 4 is fixed to the frame 4, and one end of the belt spanning the sleeve 5 passed through the frame on the opposite side (bedside) of the floor is fixed to the belt take-up roller 6 provided at the lower portion of the sleeve 5. At this time, the number and width of bands 2 and 3 are determined according to the condition of the cared person's body, divided into several pieces, and the divided part is in the clockwise direction and the remaining part is in the counterclockwise direction. Install. (This figure shows an example in which bands of 5 cm square are wrapped alternately one by one, but the width, number, position of the bands 2 and 3, the material and shape of the core, and for winding. The installation location of the roller 6 is not particularly limited.) By doing so, when the belt take-up roller 6 rotates to the right, the belt 2 attached in the clockwise direction is strained, and in the counterclockwise direction. The attached band 3 relaxes. When the belt winding roller 6 rotates counterclockwise, the belt 3 attached in the counterclockwise direction is tensioned, and the belt 2 attached in the clockwise direction is relaxed. Therefore, when the belt in tension is used in actual use, the cared person is supported through a mattress and a mattress that are laid on the belt. The band winding roller 6 is manually operated by a handle 7 attached to the roller 6 main body.

Also, instead of this handle operation, by connecting a motor or other driving device or timer, it automatically repeats clockwise and counterclockwise rotation, and automatically reverses the situation of tension and relaxation. Can be created repeatedly.

6, 7, and 8 are cross-sectional views in a state where a non-caregiver is lying on the turning auxiliary bed, FIG. 6 is a stop position after a right rotation, FIG. 8 is a stop position after a left rotation, 7 is a diagram of these intermediate positions. This only changes the arrangement of the band of the bed slip prevention bed (in this figure, as an example, two types of bands are divided into left and right at the center and the right-handed band 2 is arranged on the left side and the left-wound band 3 is arranged on the right side. The operation method is the same as that of the bedsore prevention bed.
