Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bed slip prevention bed that can prevent bed slip that may occur when a seriously ill person or an elderly person who has difficulty moving his / her body sleeps for a long time.
[0002]
[Prior art]
When a severely ill patient or the like who is difficult to turn over by himself / herself has been bedridden for a long time, a so-called bed slip occurs at a portion that is in contact with the bed of the body and is heavy. Such bed slips occur because the subcutaneous tissue is continuously pressed in such heavy ill patients and the like, and the blood flow becomes poor and nutrition is delayed.
[0003]
Therefore, it can be understood that it is only necessary to eliminate the application of weight to a specific part of the body over a long period of time in order to prevent bed slipping in such a seriously ill patient. This can be achieved, for example, by changing the sleeping position to change the part of the body that contacts the bedding such as a bed, or by modifying the bedding such as the bed and changing the contact pressure of the part that contacts the body. It will be good if you get it.
[0004]
If the sleeping position is changed as in the former, for example, if a caregiver does this, this is a considerable amount of hard work. Such a change in body position should be performed at least once every 2 to 3 hours, and preferably about once every 1.2 hours. As described above, such care work itself is a considerable heavy labor, but it is necessary to perform it frequently as described above, and it is said that it is a very heavy work for the caregiver. I must.
[0005]
Therefore, in order to reduce the burden on the caregiver as described above, beds have been proposed that can change the contact pressure of the part in contact with the body of the sleeping person, such as the latter. One type of the bed is, for example, a bed (Japanese Patent Laid-Open No. 7-194659) configured such that a bed having a concave surface with an arc-shaped cross section can be rotated and tilted in the left-right direction. By rotating and tilting, the part of the bedridden body weight applied to the bed is changed, thereby preventing bed slippage. Others of this type are, for example, a rolling bed (Japanese Utility Model Laid-open No. 5-48925) that rolls a flat bed floor surface in the left-right direction, and a sleeping person positioned on the bed bed by rolling the bed floor surface It is intended to prevent bed slipping by releasing the congested site that has been pressed for a long time and promoting blood circulation at the congested site.
[0006]
In other types, a bed upper surface corresponding to a sleeping person's body is divided into a plurality of parts, and a part or all of them can be moved up and down alternately (Japanese Patent Laid-Open Nos. 7-303673 and 8-8-1). 675, Japanese Patent Laid-Open No. 7-8523), a part or the whole of the divided bed upper surface is alternately moved up and down to change the part that hits the bedridden body, release the congested part, and the congested part It is intended to prevent bedsores by encouraging blood circulation.
[0007]
The former type, that is, the one that tilts the sleeping surface of the bed in the left-right direction, is intended to cause the sleeping person to turn over by himself / herself, and the intention can be understood, but the proposal In the configuration, the contact surface with the bed surface of the body cannot be changed reliably, and a sufficient effect cannot be obtained.
[0008]
The latter type, that is, the bed upper surface that hits the sleeping person's body is divided into multiple parts, and each divided surface is raised and lowered alternately, divided appropriately, and raised and lowered by an appropriate height at an appropriate time interval If it is possible, the desired effect will be obtained. However, since it is necessary to divide the upper surface of the bed fairly finely, there is a problem that the structure must be complicated.
[0009]
[Problems to be solved by the invention]
Therefore, the present invention solves the problem of the former type of bed that tilts the sleeping surface of the bed in the left-right direction among the conventional techniques as described above, and by appropriately tilting the upper surface of the bed, a seriously ill patient, etc. It is an object of the present invention to provide a bed for preventing bedsores that can satisfactorily prevent bed slipping and can sleep in a healthier state by properly changing the contact surface of the body with the bed.

This bendable connection can be configured using a hinge or the like. The movable bed part is a member for a user such as a seriously ill patient to go to sleep after placing a futon or the like on the bed, and the upper surfaces of the central and both sides of the bed are provided as necessary. A plurality of pseudo-acupressure protrusions can be formed. These pseudo-acupressure protrusions may be formed directly on the upper surfaces of the central sleeping plate and the both-side sleeping plates, or a sheet-like member constituting the pseudo-acupressure protrusions may be joined thereon.
[0019]
As described above, the width direction moving means is a means for moving the movable bed portion in the width direction. When moving the movable bed portion to the right side, the central bed and the right side are provided. When the side bed is moved to the front end surface of the right side drive unit and the movable bed part is moved to the left side, the central bed and the left side bed are raised to the left side. It is necessary to configure it so that it moves to the front end surface of the drive part until it gets on each.
[0020]
The width direction moving means is not limited to a specific configuration as long as it can operate as described above.
[0021]
Moreover, the said width direction moving means can be comprised by the some branch moving means arranged in the length direction. When the width direction moving means is configured in this way, the start-up drive unit is also configured as a plurality of branch start-up drive units arranged in the length direction, and each branch start-up drive unit is configured as described above. It is appropriate to arrange them alternately with the branch movement means.
[0022]
As described above, when the width direction moving means is constituted by a plurality of branch movement means, for example, the branch movement means includes a base portion arranged to be movable in the width direction and both sides of the base portion. It is composed of two expansion / contraction mechanisms arranged so that when one is extended, the other is shortened. It can combine and it can be set as the structure which couple | bonds both the coupling members to the width direction, and extends upwards, and couple | bonds each upper end with the both ends of the said center bed which is located upwards.
[0023]
As the coupling member, it is appropriate to employ a string-like member or a belt-like member having some elasticity.
[0024]
Further, as described above, the base portion is configured to be freely movable in the width direction, but its specific configuration is free. For example, a roller or a wheel can be arranged in the lower part. Furthermore, the said base part can be comprised so that it can move only to the width direction by arrange | positioning, for example with the said expansion-contraction mechanism in the box-shaped guide member arrange | positioned toward the width direction.
[0025]
For example, the expansion / contraction mechanism can be configured as a bellows-like cylindrical body that expands by introducing air and shortens by discharging air, and a compressed air supply mechanism that draws air in and out can be connected thereto. Of course, other configurations are acceptable.
[0026]
As described above, the start-up drive unit includes a right-side start-up drive unit and a left-side start-up drive unit.
The right side raising drive unit is configured to protrude from the right side so as to raise the central sleeping plate and the right side sleeping plate of the movable sleeping plate portion moved to the right side with the right end of the left side sleeping plate as a fulcrum. Is. Further, the left side raising drive unit is configured to protrude from the left side so that the central bed and the left side bed of the movable bed unit moved to the left side are raised from the left end of the right side bed as a fulcrum. To do.
[0027]
As described above, the start-up drive unit can be configured as a plurality of branch start-up drive units arranged in the length direction. In this case, the right-side startup drive unit and the left-side startup drive unit that constitute each of the branch startup drive units are bellows-like square cylinders that extend by introducing air and shorten by discharging air. Thus, the lower side portion is not expanded and contracted, and only the upper side portion is expanded and contracted, and a bellows-like rectangular tube body is configured, and a compressed air supply mechanism for taking air in and out can be connected thereto. .
[0028]
In the initial state, each of the bellows-like rectangular cylinders is configured to be directed toward the center of the bed and obliquely upward. However, as described above, each of the bellows-shaped rectangular cylinders is configured not to expand or contract its lower side portion. For this reason, when compressed air is supplied to this, only the upper part expands, and the tip end surface gradually declines along with the extension, and when it is fully extended, it is configured to face almost the center of the bed. That is, when this is extended, the end face is in an upright state.
[0029]
Therefore, according to the bed for preventing bedsore according to the present invention, a seriously ill patient who cannot easily turn over by himself / herself is put on a bed with a thin futon on the movable bed, and the bed is separated at an appropriate time interval. The width direction moving means and the rising drive unit are driven, and the movable bed portion is sequentially moved in the width direction.For example, the position is moved back and forth between the center, the right side, the center, and the left side at predetermined time intervals. In the left position, raise the left side bed and the center bed to the upright position with the left edge of the right side bed as a fulcrum, and in the center position, Place the plate horizontally and place the side bedding on both sides on the tip of the right-side riser drive unit and left-side riser drive unit to return to the diagonally upward state. The right end of the left side bed is the fulcrum for the bed and center bed By moving the robot so that it stands up to an almost upright state, the posture can be easily changed to right sideways, upwards, left sides, and the like, without forcibly and helping the seriously ill patients. be able to.
[0030]
Moreover, when changing the direction of the body in this way, for example, when changing the direction of the body to the right, the movable bed part on which the body is placed is moved to the left and the direction of the body is changed to the left Because the movable bed part on which the body is placed is moved to the right side, the body is always located at the center in the width direction of the bed and does not become unstable such as falling from the bed. .
[0031]
This is described in detail as follows.
First, in the initial state of the bed, the central bed of the movable bed part is positioned in the center and is in a horizontal state, and the side bed on both sides is the right side drive unit and the left side in a shortened state. They are in contact with the front end surfaces of the start-up drive parts and are in an obliquely upward state, that is, their upper surfaces are directed upward in the center. Incidentally, since the right side raising drive unit and the left side raising drive unit are respectively arranged obliquely upward toward the center in the width direction as described above, the front end surface thereof is the outer side in the shortened state. It is in the diagonally upward state where becomes higher.
[0032]
Therefore, a seriously ill patient who sleeps with a thin futon or the like on the movable bed part, in the initial state of the bed, the body is slightly due to the central bed and the side bed on both sides of the movable bed part. It is like being surrounded.
[0033]
In this state, for example, when the width direction moving means is operated to move the movable bed portion to the left side, a seriously ill patient sleeping on the left side also moves to the left side. When the left side bed and the central bed on the left side of the movable bed part move until they are placed on the front end surface of the left side rise drive part, the left side rise drive part is then raised and operated. The left side bed and the center side bed rise up with the left end of the right side bed as a fulcrum and become almost upright.
[0034]
When a predetermined time has elapsed, the width direction moving means is operated to move the movable bed part to the right side, and when the central bed part is returned to the center part, naturally, the bed rests on the movable bed part. Seriously ill patients who are back will return to the center. When the movable bed part moves to the central part, the left side rise drive part of the rise drive part is shortened to return to the initial state, and the movable bed part also returns to the initial state.
[0035]
Thereafter, after a predetermined time has elapsed, when the width direction moving means is operated to move the movable bed portion to the right side, seriously ill patients who are sleeping on the same naturally move to the right side. To do. When the right side bed and the center bed on the right side of the movable bed part move until they are placed on the front end surface of the right side rise drive part, the right side rise drive part protrudes and subsequently operates. The right side bed and the center side bed rise with the right end of the left side bed as a fulcrum, and are almost upright.
[0036]
In addition, when a predetermined time has elapsed, the widthwise moving means is operated to move the movable bed portion to the left side, and when the central bed portion is returned to the center portion, naturally, it is placed on the movable bed portion. Seriously ill patients who go to bed will also return to the center. When the movable bed portion moves to the central portion, the right side raising drive portion of the raising drive portion is subsequently shortened to return to the initial state, and the movable bed portion also returns to the initial state.
[0037]
Thereafter, the operation described above is repeated.
As described above, the movable bed part on which a seriously ill patient or the like sleeps through a futon, etc. moves every predetermined time, and when moved to the left side, the left side bed and the central bed are moved to the left side. Because the board stands almost upright, seriously ill patients, etc., are placed on the right side bed and turned to the right, and when returning to the center, seriously ill patients, etc. are on the central bed. When it is moved upward and moved to the right side, the right side bed and the center bed rise almost upright, so seriously ill patients etc. face the left side while resting on the left side bed. It will be in the state. And since the posture is changed every predetermined time in this way, the part that contacts the bed upper surface of the body changes appropriately, and the generation of the part where the blood flow deteriorates for a long time can be avoided. Occurrence can be prevented in advance.
[0038]
As described above, even when changing the orientation of the body in this way, the position on the bed on which the body is placed is always located in the center in the width direction, so that it is unstable such as falling from the bed There is no state.
[0039]
Further, when a plurality of pseudo acupressure protrusions are formed on the upper surfaces of the central and both sides of the movable bed part, the effect of preventing bed slip can be further enhanced by the action.
[0040]
