Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor-rubbing prevention bed which can change the posture of a bedridden sick person by moving the bed mattress in a wavy manner in order to prevent the sick person from rubbing the floor.

[0002]

[Prior Art]

 For sick people who are bedridden for a long period of time and are unable to turn themselves, especially elderly sick people, the floor rubs if left untouched, so the caregiver (nurse) sometimes changes the sick person's posture. There was a need.

[0003]

[Problems to be solved by the device]

 When a caregiver changes the posture of a sick person to prevent sickness from rubbing on the floor, he must be careful with his physical condition because he cannot move on his own. It was a heavy work to do mentally.

Therefore, the present invention has been made based on the above-mentioned circumstances, and for preventing floor rubbing of a bedridden sick person, it is possible for a caregiver to easily change the posture of the sick person for floor rubbing prevention. The purpose is to provide a bed.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a floor scrub prevention bed according to the present invention comprises a plurality of elevating members dispersed in a frame of a bed, and a mattress is placed on each elevating member. It is characterized in that a displacement sensor for detecting the amount of elevation is attached to the controller, and a control device for operating the respective elevation members in cooperation while referring to the detection data of each displacement sensor is provided.

[0006]

[Advantage] In the present invention, a large number of lifting members dispersed in the frame of the bed are raised and lowered by a control device in cooperation with each other, and the mattress laid across the plurality of lifting members is wavy. Prevent the patient from rubbing on the floor by changing the posture of the sick person on the mattress and providing gaps between the mattress and the sick person.

[0007]

【Example】

 Hereinafter, the floor-rubbing prevention bed according to the present invention will be described in detail. In the bed of the present invention, a large number of lifting members 3 are installed upright in a frame 2 of the bed 1, a mattress 4 is placed over each lifting member 3, and the lifting amount of each lifting member 3 is adjusted. A displacement sensor 6 for detecting is attached, and a control device 5 for operating each elevating member 3 in cooperation with each other while referring to the detection data of each displacement sensor 6 is provided.

In this embodiment, an air cylinder is used as the lifting member 3, and the cylinder body 7 of each air cylinder 3 is fixed in the frame 2 of the bed 1. The air cylinder 3 may be arranged in any suitable manner as long as it is appropriately dispersed in a plane. For example, the air cylinders 3 may be arranged in a grid pattern as shown in FIG. 2 or in a staggered pattern.

The control device 5 is installed at a position where a caregiver can easily operate, such as a side of a bed, and a small compressor (not shown) for supplying air to each air cylinder 3 prevents noise from being offensive to the sick person. Moreover, it is desirable to place it in an inconspicuous position.

In this control device 5, the position of the push-up pad 8 of each air cylinder 3 is constantly grasped by the detection signal of the displacement sensor 6 attached to each air cylinder 3. As the displacement sensor 6, for example, a magnetic sensor that magnetically detects the position of the piston 11 is used. Normally, the upper end of the push-up pad 8 of each air cylinder 3 is aligned at a constant height (the lowest position), and the sick person lies on the mattress 4 placed on each air cylinder 3 horizontally.

In addition, the control device 5 refers to the detection data of the displacement sensor 6 attached to each air cylinder 3 in accordance with a pre-installed program, and supplies and exhausts the exhaust gas 9 at the tip end side and the base end side of each air cylinder 3. , 10 and a compressor (not shown) are individually opened and closed at appropriate times by controlling solenoid valves (not shown) so that each air cylinder 3 is controlled to move up and down in cooperation with each other. There is.

The manner in which each air cylinder 3 moves up and down in cooperation can be appropriately changed or added by modifying the program incorporated in the control device 5. For example, each air cylinder can be fed forward from the left side of the bed to the right side or in the reverse direction. 3 or when the push-up pad 8 of the center air cylinder 3 is low and the push-up pads 8 of the air cylinders 3 on both sides extend as high as possible. The mattress 4 on the air cylinder 3 is moved in a wavy manner by alternately repeating the state in which the push-up pad 8 of the air cylinder 3 is extended higher.

Therefore, the caregiver of the bedridden sick man operates the control device 5 to move the mattress 4 in a wavy manner by a large number of air cylinders 3, so that the sick man on the mattress 4 may be turned over by himself. By changing the posture and creating an appropriate gap between the mattress 4 and the sick person, it is possible to prevent bedridden sick people from rubbing the floor. This control device 5 is provided with a safety device for preventing malfunction so that anyone can easily use it by a simple switch operation.

Further, in each of the air cylinders 3 described above, the air supply / exhaust port 9 on the front end side is blocked while the air supply / exhaust port 9 on the front end side is blocked in a state where an appropriate amount of air is contained in the cylinder body 7. By sending air from 10 to the cylinder body 7 at an appropriate delivery pressure, it can be used as an air cushion (air spring) instead of the sprinkling of the bed 1.

The air cushion composed of the air cylinders 3 described above has a softness of the air cushions by adjusting the air pressure sent from the air supply / exhaust port 10 on the proximal side of the air cylinder 3 into the cylinder body 7. That is, the spring constant can be set arbitrarily. Therefore, the softness of the air cushion can be adjusted according to the mood of the user (physical condition of the sick person) to provide comfortable sleeping at any time, and it is also effective for preventing bed rub for bedridden sick people.

A hydraulic cylinder may be used as the lifting member 3 instead of the air cylinder. When a hydraulic cylinder is used, the structure is almost the same as that of the air cylinder described above, the mattress 4 can be moved in a wavy manner, and the softness of the cushion of the bed can be arbitrarily adjusted.

In addition, it is also possible to use, as the elevating member 3, a mechanism that mechanically moves up and down by a motor, such as a ball screw. When using a ball screw, as shown in FIG. 4, each ball screw 3 is provided with an elevating motor 13 for rotating the vertical rotating shaft 12 in the forward and reverse directions, and a nut that moves up and down in accordance with the forward and reverse rotation of the rotating shaft 12. A push-up pad 8 is attached to 15 via a support member 16, and the displacement sensor 6 measures the rotation of the rotary shaft 12 or moves up and down along the guide frame 14 of the ball screw 3 (the push-up pad 8 and Any one of the nut 15 and the supporting member 16) for measuring the position is attached, and the control device 5 refers to the measurement data of the displacement sensor 6 and operates the lifting motors 13 according to a pre-installed program. Try to control in coordination.

[0018]

[Effect of the device]

 The floor-rubbing prevention bed according to the present invention has a plurality of lifting members distributed upright in the frame of the bed as described above, and a mattress is placed over each lifting member, and the lifting amount is adjusted on each lifting member. Since a displacement sensor for detection is attached and a control device that operates each elevating member in cooperation with reference to the detection data of each displacement sensor is provided, the caregiver can operate the elevating member only by operating the control device. The mattress can be waved through the bed to change the posture of the sick person on the bed, and an appropriate gap can be created between the mattress and the sick person to easily prevent the bedridden sick person from rubbing the floor.
