DETAILED DESCRIPTION OF THE INVENTION
The present invention basically includes a split mattress composed of a back corresponding part, a waist corresponding part and a leg corresponding part, a undulation drive mechanism for raising and lowering the back corresponding part, and the back corresponding part and the waist corresponding part of the bed main body. A reciprocating drive mechanism for reciprocating between the rear end (the end on the leg portion side of the sleeping person) and the leg corresponding portion enter the lower portion corresponding to the back portion and the waist corresponding portion so as to freely advance and retract. This is a care bed composed of an advancing / retreating drive mechanism, a toilet placed below the leg-corresponding portion, and an underarm support portion used when the care receiver is seated on the toilet or on a wheelchair.
[0011]
Of the divided mattresses, the back corresponding portion and the waist corresponding portion have a function as a general mattress and are connected to each other by a hinge or the like so that the back corresponding portion can be raised and lowered. The back-corresponding part and the waist-corresponding part constitute a moving means in the front-rear direction at the corresponding parts of the both side parts and the bed body, respectively. For example, it can be set as the structure which provides a slide member in each both sides, and these are slidably mounted on the guide rail distribute | arranged to the corresponding | compatible part of the bed main body. Alternatively, a rotatable roller member can be attached to each of both side portions, and these can be slidably mounted on guide rails arranged at corresponding portions of the bed main body.
[0012]
Among the divided mattresses, the leg-corresponding portion includes a rotatable roller member disposed at the front end and the rear end thereof, an endless belt member spanning the roller member, and a sliding member disposed directly below the endless belt member. It is appropriate to configure with a surface member. By configuring in this way, as will be described later, the back corresponding portion is raised to raise the care receiver sleeping on the bed, and in this state, the back corresponding portion and the waist corresponding portion are set to the leg portions of the bed main body. When sliding to the end side, the cared person's leg can smoothly move beyond the leg side end of the bed main body without stagnation on the leg corresponding part. It is.
[0013]
Similarly to the back-corresponding part and the waist-corresponding part, the leg-corresponding part also includes moving means in the front-rear direction at the corresponding parts of both sides and the bed body. For example, it can be set as the structure which provides a slide member in the both sides, and these are slidably mounted on the guide rail distribute | arranged to the corresponding | compatible part of the bed main body. Alternatively, a rotatable rolling roller can be attached to both sides of the roller, and these can be placed on a guide rail disposed on a corresponding part of the bed body so as to be freely rollable. In any case, the above-mentioned guide rail should be arranged at the height position because the leg-corresponding portion needs to move forward and backward under the back-corresponding portion and the waist-corresponding portion.
[0014]
In addition, since the said leg corresponding | compatible part will be located in the position lower than the said back | dorsal corresponding | compatible part and a waist | hip | lumbar part corresponding | compatible part at least by the thickness, when the care receiver is only sleeping, the dent is inconvenient. become. Therefore, it is appropriate to arrange an auxiliary mat or the like to compensate for this dent.
[0015]
The raising / lowering drive mechanism for raising / lowering the back portion corresponding portion is not limited to a specific one as long as it is a mechanism capable of raising / lowering the back portion corresponding portion. For example, a hydraulic or pneumatic cylinder is adopted as the main device, and the lower end of the cylinder body is pinned to a part of a support frame fixed to the waist corresponding portion, and the tip of the rod is connected to the back corresponding portion. It can be configured by pin-bonding to the back surface.
[0016]
As the undulation drive mechanism, when a mechanism using a pneumatic cylinder as described above is formed below the back portion corresponding portion, or similarly, a mechanism having another configuration located below the back portion corresponding portion. In any case, it is necessary to adjust the mutual relationship so as not to cause interference because the leg corresponding part enters the lower part corresponding to the back part so as to freely advance and retreat.
[0017]
For example, even if an undulating drive mechanism using a pneumatic cylinder or the like to be configured below the back corresponding part is installed on both sides of the lower part thereof, and the leg corresponding part enters below the back corresponding part, For example, it is configured to be narrow so as not to contact the undulation drive mechanism.
[0018]
The reciprocating drive mechanism is not limited to that of a specific configuration as long as the back corresponding portion and the waist corresponding portion can be driven to reciprocate. This reciprocating drive mechanism can also be configured to drive the back corresponding portion or the like forward or backward by utilizing the expansion or contraction operation of a hydraulic or pneumatic cylinder. Or, using an electric motor, this is attached to the lower part of the waist corresponding part, etc., and a pinion coupled to the drive shaft of the electric motor via a speed reducer or the like is driven to rotate forward and backward, and this is connected to the back corresponding part etc. The rack can be arranged in the range to be reciprocated in accordance with the direction of the rack, and meshed with the rack so as to reciprocate along the rack. Of course, other configurations can be freely adopted. However, the leg-corresponding portion needs to be installed in a positional relationship that does not hinder downward entry of the back-corresponding portion or the like.
[0019]
The advance / retreat drive mechanism is not limited to that having a specific configuration as long as the leg corresponding portion can be moved back and forth within the predetermined range. This forward / backward drive mechanism can also be configured similarly to the reciprocating drive mechanism. As described above, the positional relationship is a position at a height immediately below the back corresponding part and the waist corresponding part.
[0020]
The toilet is disposed below the leg corresponding portion, and a lower part of the toilet needs to be provided with a toilet tank for receiving the feces excreted by the toilet. In order to prevent odors and the like from being scattered around, it is preferable to provide means for holding the interior of the interior at a negative pressure during the stool. Moreover, it is preferable to provide a water washing means so that the inside of the toilet bowl can be washed after the toilet.
[0021]
  The armpit support portion raises the back corresponding portion of the split mattress, and when it is moved to the rear end side of the bed main body together with the waist corresponding portion, it is raised by the back corresponding portion and moves to the rear end side of the bed main body. The rod-shaped support material is inserted into the armpit of the cared person, and the caring person is raised while supporting the cared person. It can be used to move to the lower part of the toilet to expose the toilet in the lower part, and to lower the rod-like support material of the armpit support part so that the care recipient sits on the toilet, and vice versa. It must be possibleThe
[0022]
Therefore, specifically, the armpit support portion is arranged such that the pair of rod-shaped support members can be directed to the rear end of the bed main body so that the leg corresponding portion side is directed to the armpit. The rod-shaped support material is configured to be able to move up and down in an obliquely upward direction at the rear of the bed body so that the cared person who is supported can stand up outside the rear end of the bed body. is there.
[0023]
  More specifically, the armpit support portion is formed between a pair of support legs that are lifted up and down and retractable from both sides near the rear end of the bed body, and between the upper ends of the support legs. A pair of rod-shaped support members that are connected to each other and are pivotally attached to both ends of the gap, with a gap at an interval exceeding the shoulder width of a person at the center of the coupling member It is sometimes composed of a rod-shaped support material that is configured so that the entirety thereof is placed on the connecting member and can be rotated so as to be parallel to each other above the bed body when used.thingIt is.
[0024]
  Further, the armpit support portion as described above is configured such that each of the pair of support legs and each end of the connecting member are coupled so that the latter is rotatable and detachable in the horizontal direction with respect to the former. In addition, an auxiliary leg extending from the vicinity of both ends of the connecting member to the outside of the rear end of the bed body is provided, and a free wheel is attached to the lower end of the auxiliary leg.It is a thing.
[0025]
Therefore, according to the care bed of the present invention, as described below, when an elderly person or a seriously ill person who cannot get up by himself / herself is laid down, the upper body is raised, the stool is used, or the bed It is convenient that such an operation can be easily assisted when the robot is taken down and moved to a wheelchair or the like.
[0026]
In order to raise the upper body of the cared person sleeping on the care bed of the present invention, the raising / lowering driving mechanism is operated, and the back corresponding portion of the divided mattress is operated upright. As a result, the cared person is pushed up from the back and gradually raises the upper body. Of course, in this case, as necessary, the part of the blanket or futon on the body that is on the upper body is folded back toward the bottom of the foot, or the whole is removed.
[0027]
  When the upper body is raised for stool, the comforter and the like are removed and the auxiliary mat placed on the leg-corresponding portion of the divided mattress is removed, and then the reciprocating drive mechanism is operated. The back corresponding part and the waist corresponding part of the divided mattress are moved to the rear end side of the bed main body. In this way, the cared person is moved to the rear end side of the bed main body, and finally both legs are suspended from the rear end of the bed main body. When such a cared person moves, both legs thereof move to the rear end side of the bed main body on the leg corresponding portion. As described above, this is a roller member that is rotatable. And an endless belt member that spans them, and a smooth surface member that is disposed directly below the endless belt member.ForThe upper side of the belt member moves in the same direction as the legs of the cared person move, so it can be moved easily without excessive friction.TheConvenient.
[0028]
In this way, when the cared person moves to the rear end of the bed main body and the both legs are suspended from the part, or before that, the pair of rod-like support members of the armpit support part is attached to the person. If you turn the bed main body in parallel with the width of the armpit, you can insert each into the armpit of the cared person who has been moved, and raise the upper body of the cared person by these Can be supported. If you prepare a belt for back support, turn it around the back of the cared person, and connect both ends of the belt to the ends of the pair of rod-shaped support materials, making the cared person safer Highly supportable.
[0029]
From the above state, when the rod-like support material of the armpit support portion is raised obliquely upward toward the back of the bed body, the cared person is gradually moved backward while being supported by the armpit. However, it moves to the outside of the rear end of the bed body and stands up.
[0030]
While holding the cared person under the armpit in this way, the reciprocating drive mechanism is operated, the back corresponding portion and the waist corresponding portion of the divided mattress are returned to the predetermined positions, and at the same time or The advancing / retreating drive mechanism is sequentially operated to move the leg mating portion of the split mattress below the back corresponding portion and the waist corresponding portion that have returned to their home positions.
[0031]
Thus, when the leg corresponding part moves downward from the fixed position such as the back corresponding part, the toilet covered with the leg corresponding part appears from below. Here, when the rod-like support member of the armpit support part is lowered, the rod-like support member is lowered obliquely toward the front of the bed main body, contrary to the above-described operation. The cared person descends as he descends and finally sits on the toilet.
[0032]
Therefore, before starting the downward movement of the bar-like support material of the armpit support part, if the care recipient is standing and taking measures such as removing necessary clothes, the bar-like support material is only necessary. By performing the lowering operation, the cared person can be seated on the toilet bowl in a state where stool can be used as described above. In this state, the cared person can perform the defecation operation while being safely protected by the rod-shaped support member and the belt on the back.
[0033]
After the defecation is finished, the rod-shaped support material is moved up, the cared person is raised, the necessary treatment is taken, and the clothes are put on, before and after this, the advance / retreat drive mechanism is operated, The leg mating portion of the split mattress is returned to a fixed position, that is, on the toilet. Needless to say, the flushing means of the toilet should be operated at an appropriate time.
[0034]
After this, or simultaneously with returning the leg corresponding portion to a fixed position, the reciprocating drive mechanism is operated, and the back corresponding portion and the waist corresponding portion of the divided mattress are moved to the rear end side of the bed body, Next, the rod-like support material of the armpit support part is moved down to allow the care recipient to sit on the waist corresponding part located on the leg corresponding part. At this time, if the back corresponding part has been returned to the prone state, the hoisting drive mechanism is operated to stand up again, and if it is kept in the upright state, the upright state is maintained as it is. While maintaining, the belt of the armpit support part that supported the back of the cared person is removed so as to lean against the back corresponding part.
[0035]
In this state, the reciprocating drive mechanism is operated to return the back corresponding part and the waist corresponding part to the fixed positions, and then the hoist driving mechanism is operated to return the back corresponding part to the prone state. In addition, if an auxiliary mat is placed on the leg-corresponding portion, and the comforter that has been removed first is placed on the cared person, all of the operations for defecation from the sleeping state and for returning to the sleeping state Is completed.
[0036]
Next, a case where the care recipient is lowered from the bed and moved to a wheelchair or the like will be described.
In this case, the procedure is the same as that for the above-described stool until the cared person is moved to the rear end of the bed main body and is raised using the armpit support portion at this position. Therefore, the subsequent operation will be described.
[0037]
At this stage, that is, at the stage where the caregiver is raised by inserting the rod-shaped support material of the armpit support portion under both armpits, an appropriate one of the connecting portions between the both ends of the connecting member and the support legs. Solve the bond.
[0038]
Next, when the connecting member is slowly rotated outward about the other supporting leg that maintains the connection, the cared person supported by the pair of rod-like support members of the armpit support portion on both sides is Following this, it slowly moves in that direction, for example, if the connecting member is rotated until it becomes parallel to the length direction of the bed body, the back side of the cared person is behind the bed body. The state can be shifted to a direction orthogonal to the length direction.
[0039]
When the cared person is moved to the back of the bed main body as described above, and the back is turned in the direction perpendicular to the length direction of the bed main body as described above, a wheelchair is placed behind the cared person. It becomes easy to move, and the cared person can sit down easily by simply sitting down on the wheelchair moved to the back.
[0040]
Thereafter, the wheelchair is moved from this position, the connecting member is rotated in the reverse direction, and then the removed end is connected to the corresponding support leg.
[0041]
  In addition, when the above connecting member is rotated, auxiliary legs are formed near both ends of the connecting member, and a free wheel is attached to the lower end of the auxiliary leg.Because it is as a configuration, Its operation becomes stableThe
[0042]

[0061]
Therefore, according to the nursing bed of this embodiment, when the upper body of the elderly person or seriously ill person who cannot get up by himself / herself is laid on this, It is convenient that such an operation can be easily assisted when it is made to move from the bed to a wheelchair or the like.
[0062]
First, when raising the upper body of the care receiver sleeping on the care bed of this embodiment, the undulation drive mechanism 3 may be operated, and the back corresponding portion 2a of the divided mattress 2 may be operated upright. This can be done by extending the pneumatic cylinders 3b, 3b of the undulation drive mechanism 3, as shown by the one-dot chain line in FIG. On the other hand, it goes without saying that the pneumatic cylinders 3b and 3b may be shortened to return to the original lying state.
[0063]
When the back corresponding portion 2a in the divided mattress 2 is thus raised, the cared person is pushed up from the back, and the upper body is gradually raised. Of course, in this case, if necessary, a part of the blanket or futon that is worn on the body is folded back toward the lower part of the upper body, or the whole is removed.
[0064]
When the upper body is raised for stool, the comforter and the like are removed, and the auxiliary mat 2d placed on the leg-corresponding portion 2c of the divided mattress 2 is removed, and then the reciprocation is performed. The drive mechanism 4 is operated to move the back corresponding part 2a and the waist corresponding part 2b of the divided mattress 2 to the rear end side of the bed main body 1.
[0065]
When the electric motor 4c is rotated in a predetermined direction, the waist corresponding portion 2c is moved in the rear end direction of the bed body 1 of the wire 4b via the fixed shafts on the rear of the rolling rollers 8 and 8 on both sides. With the side pulled in this direction and the back corresponding part 2a raised, the back corresponding part 2a and the waist corresponding part 2b are moved until the latter comes into contact with the rear end of the bed main body 1.
[0066]
In this way, the care recipient is moved to the rear end side of the bed main body 1, and finally both legs are suspended from the rear end of the bed main body 1. When such a cared person moves, both legs move so as to slide on the leg corresponding part 2c to the rear end side of the bed body 1, and at this time, the leg parts Since the upper surface of the corresponding portion 2c is composed of an endless belt member 2c2 stretched around the rotatable roller members 2c1 and 2c1, the upper surface moves in the same direction as the leg of the care recipient is moved. As a result, excessive friction or the like does not occur, and it can be moved easily.
[0067]
In this way, when the cared person moves to the rear end of the bed main body 1 and both legs are suspended from the part, or before that, the armpit as shown by a one-dot chain line in FIG. The pair of rod-like support members 7c, 7c of the support portion 7 is rotated in a state of being parallel to the width of the person's armpit and facing the front side of the bed main body 1. Thus, the rod-shaped support members 7c and 7c are inserted into the armpit of the cared person who has been moved, and thus the upper body of the cared person can be reliably supported.
[0068]
Thereafter, the belt 7c1 connected to one of the rod-shaped support members 7c is turned around the cared person's back, and the ring at the other end of the belt 7c1 is connected to the hook portion at the tip of the other rod-shaped support material 7c. To do. Thus, the cared person can be supported with higher safety.
[0069]
From this state, when the rod-like support member 7c of the armpit support portion 7 is lifted obliquely upward toward the rear of the bed body 1, the cared person is supported by the armpit and back, and the upper body gradually moves backward. It moves to the rear end of the bed main body 1 while being moved to stand up. The above-described lifting of the rod-shaped support members 7c and 7c can be performed by driving the lifting / lowering driving means 7d to lift and thereby lifting both the support legs 7a and 7a in the same direction.
[0070]
In the elevating drive means 7d, the electric motor 7d5 is rotationally driven in a predetermined direction, thereby pulling the side of the wire 7d4 that is stretched over the end pulley 7d3 and thereby sliding to the guide cylinder 7d1. The support legs 7a that are freely guided are pulled up through coupling protrusions 7a1 formed at the lower part thereof, and the rod-shaped support members 7c and 7c are raised through the lifting operation of the support legs 7a.
[0071]
The cared person is thus supported under the arm by the rod-shaped support members 7c and 7c and supported by the back by the belt 7c1, and the reciprocating drive mechanism 4 is operated while the rising state is maintained, so that the divided mattress 2 The back corresponding part 2a and the waist corresponding part 2b of the split mattress 2 are returned to the fixed positions by operating the advancing / retreating drive mechanism 5 at the same time or sequentially to return the leg corresponding parts 2c of the divided mattress 2 to the fixed positions. It moves below the corresponding part 2a and the lower part corresponding part 2b.
[0072]
At this time, when the electric motor 4c is rotated in the direction opposite to the predetermined direction in the reciprocating drive mechanism 4, the waist corresponding portion 2c is moved to the front of the rolling rollers 8 and 8 on both sides. The front end direction side of the bed body 1 of the wire 4b is pulled in this direction via a fixed shaft, and the back portion corresponding portion 2a and the waist portion corresponding portion 2b are raised by the former while the back portion corresponding portion 2a is raised. It moves until it touches the front end of 1.
[0073]
At this time, in the forward / backward drive mechanism 5, when the electric motor 5c is rotated in a predetermined direction, the leg corresponding portion 2c is fixed to the front of the rolling rollers 10 and 10 on both sides. The front end direction side of the bed body 1 of the wire 5b is pulled in this direction via the shaft, and the leg corresponding portion 2c is moved until the rear end enters forward from the rear end of the waist corresponding portion 2b that has returned to the fixed position. It is something to be made.
[0074]
Thus, when the leg corresponding part 2c moves below the waist corresponding part 2b and the like returned to the home position, the toilet 6 covered with the leg corresponding part 2c appears from below. Here, when the rod-like support members 7c, 7c of the armpit support portion 7 are lowered, the rod-like support members 7c, 7c are moved obliquely downward toward the front of the bed main body 1, contrary to the above. Therefore, the cared person supported by this and the belt 7c1 descends as it descends, and finally sits on the toilet bowl 6.
[0075]
The lowering of the rod-like support members 7c and 7c as described above is performed by driving the elevating drive means 7d to lower and thereby lowering both the support legs 7a and 7a in the same direction.
[0076]
At this time, the elevating drive means 7d pulls the side of the wire 7d4 that is stretched over the end pulley 7d3 by rotating the electric motor 7d5 in the direction opposite to the predetermined direction, The support leg 7a slidably guided by the guide cylinder 7d1 is pulled down through a coupling protrusion 7a1 formed at the lower portion thereof, and the rod-like support members 7c and 7c are lowered through the lowering operation of the support leg 7a. Is.
[0077]
Therefore, if the care recipient is standing before taking care of standing before the start of the lowering operation of the rod-like support members 7c, 7c of the armpit support portion 7, the rod-like support material will be removed. By lowering 7c and 7c as much as necessary, the cared person can be seated on the toilet 6 in a state where the toilet can be used as described above. In this state, the cared person can perform the defecation operation while being safely protected by the rod-shaped support members 7c and 7c and the belt 7c1 behind.
[0078]
After the defecation is finished, the elevating drive means 7d is driven to move up and the support legs 7a7a are moved up, thereby raising the rod-shaped support members 7c and 7c, thereby raising the cared person. Take necessary measures, put on clothes, and before and after this, the advance / retreat drive mechanism 5 is operated, and the leg corresponding portion 2c of the divided mattress 2 is placed in a fixed position, that is, on the toilet bowl 6 Return. Needless to say, the flushing means of the toilet 6 should be operated at an appropriate time.
[0079]
After this, or at the same time as returning the leg corresponding part 2c to the fixed position as described above, the reciprocating drive mechanism 4 is operated, and the back corresponding part 2a and the waist corresponding part 2b of the divided mattress 2 are moved to the bed. The body 1 is moved to the rear end side, and then the rod-like support members 7c and 7c of the armpit support portion 7 are moved downward to move the care recipient to the waist corresponding portion 2b located on the leg corresponding portion 2c. Sit on top. At this time, since the back corresponding portion 2a is in an upright state, the belt 7c1 supporting the back of the cared person is removed and the back corresponding portion 2a is leaned against the back corresponding portion 2a while maintaining the state. To do.
[0080]
In this state, the reciprocating drive mechanism 4 is operated to return the back corresponding portion 2a and the waist corresponding portion 2b to their home positions, and the raising / lowering driving mechanism 3 is further lowered to lower the back corresponding portion 2a. Return to the state, and then place the auxiliary mat 2d on the leg corresponding part 2c, and in addition, place the comforter etc. removed previously on the cared person, then defecate from the sleeping state, and again The operation to return to the sleeping state is completed.
[0081]
As described above, the back-corresponding portion 2a that has stood up returns to the original prone state by shortening the pneumatic cylinder 3b of the hoisting drive mechanism 3.
[0082]
Next, a case where the care receiver is lowered from the bed and moved to the wheelchair C to be seated will be described.
In this case, the procedure is the same as the above procedure until the cared person is moved to the rear end of the bed body 1 and the armpit support portion 7 is used to stand up at this position. Therefore, the subsequent operation will be described.
[0083]
At this stage, that is, the cared person was raised after inserting the rod-like support members 7c, 7c of the armpit support portion 7 under the both sides, and supporting from the back with the belt 7c1 disposed between the tips. In the step, one of the coupling portions between the both ends of the connecting member 7b and the support legs 7a and 7a is released.
[0084]
Here, as shown in FIG. 5, for example, the coupling of the coupling portion at the right end of the connecting member 7 b is to be released. As shown in FIG. 6, this can be easily performed by removing the inclusion 12 from the connecting hole 7b1 of the connecting portion. When the inclusion 12 is removed, the connecting member 7b can be rotated counterclockwise around the connecting pin 7a1 of the left end support leg 7a. This is because the connecting pin 7a1 of the corresponding support leg 7a can be pulled out from the extracted connecting hole portion 7b1 through the notch portion 7b2.
[0085]
In this way, when the connecting member 7b is slowly rotated counterclockwise around the connecting pin 7a1 of the left support leg 7a maintaining the connection, a pair of rod-like support members 7c of the armpit support portion 7 is provided. , 7c supported by both armpits and back supported by the belt 7c1, the cared person slowly moves in the direction following this, and the connecting member 7b is moved to the bed body as shown in FIG. When it is rotated until it becomes parallel to the length direction of 1, the back side of the cared person can be shifted to a state in which the back side of the caregiver is oriented in the direction orthogonal to the length direction behind the bed body 1.
[0086]
When the cared person is moved to the rear of the bed main body 1 as described above and the back is turned in a direction perpendicular to the length direction of the bed main body 1 as described above, as shown in FIG. The wheelchair C can be easily moved behind the cared person, and the cared person can easily sit on the wheelchair C moved behind by simply sitting down. Needless to say, the belt 7c1 should be removed in advance.
[0087]
Thereafter, the wheelchair C on which the cared person rides is moved from the position, and then the connecting member 7b is rotated in the opposite direction, and the support leg 7a corresponding to the connecting hole 7b1 at the end of the removed side. In addition, the connecting pin 7a1 is introduced, and the inclusion 12 is fitted and connected to the connecting hole 7b1 while the connecting pin 7a1 is rotatably inserted into the central hole.
[0088]
