Description

Specification

TECHNICAL FIELD The present invention relates to a mat laid on a movable bed for nursing care. Technology background

Generally, a movable bed used for a turning support bed or the like is inclined on a part or the whole of the mat surface of the bed on which the care recipient is placed in order to prevent occurrence of so-called bedsores of the care recipient who is the user. The patient is turned over in the tilt direction to support the posture change (see Japanese Patent Application Laid-Open No. 6-14824). Most of such turning support beds have a mechanism for tilting the mat surface from the flat state toward the mat width direction when supporting posture change.

However, when the movable bed moves, the mat laid on the movable bed may be displaced, and the position of the care recipient may be deviated from the correct position. Such problems prevent the normal operation of the movable bed, and there is room for improvement in terms of the safety of the care recipient. Disclosure of the invention

In order to solve the above problems, the present invention is a movable bed mat laid on the floor of a movable bed in which the bed surface is deformable, and the mat surface facing the floor is engaged with the floor. Fittings were provided.

According to such a configuration, when the movable bed is driven, the mat is prevented from being displaced relative to the bed surface, so that the care recipient lying on the bed can safely and correctly posture to the posture conversion. You can hope for a good night's sleep.

Specifically, the movable bed may have a mesh formed on the floor, and the fixture may be configured to be fitted in the gap of the mesh to fix the mat. In this case, it is desirable that the fixture be removable from the floor of the movable bed, as this facilitates replacement of the mat and maintenance of the movable bed.

It is preferable that the fixing tool be disposed on the surface of the mat at a position corresponding to the waist of the user lying on the mat, since the expansion and contraction of the mat becomes easy when the bed is in operation.

As an example of the movable bed to be applied to the present invention, the movable bed may be a floor having a flexible floor and a floor having a bend, including bending at least one of raising and knee lifting. The bending mechanism includes a bending mechanism for forming a posture, and a tilting mechanism for laterally tilting the floor surface of the floor, wherein one of the bending mechanism and the tilting mechanism is configured to be operable in the operating state of the other mechanism. Are listed. Brief description of the drawings

1-1. Configuration of a rollover support bed

FIG. 1 is a perspective view showing the configuration of a turn around bed 2 according to a first embodiment of the present invention.

The turning support bed 2 has a movable stage 20 mounted on a fixed stage 30 and a bed frame 10 disposed thereon.

The bed frame 10 has a total of four joint parts, back, waist, thighs, and knees, in accordance with the position of the surface of the bed, which corresponds to the position of the body when the care recipient is lying on the bed. It is divided, and it has connected floor parts lla to lld formed by movably connecting these. The upper floor plate 11a, the lower back plate lib, the upper thigh plate 11c, and the lower knee plate lid are connected in the same order in the connection floor portions lla to lld. Since the lumbar plate lib is fixed directly to the movable stage 20 by welding or the like, the bed frame 10 never comes off the movable stage 20. And the side members 12Ra-12Rd and 12La-12Ld for supporting a patient's body side are each connected with the left-right both sides of each connection floor part lla-lld. The upper body plate 11a and the thigh plate 11c of the bed frame 10 are the L-shaped connecting member with the axis of the linear motion actuators Ml and M2 (see the bed top view in FIG. 3) disposed on the center beam 21A of the movable stage 20. Since it is connected via 211 and 212, the care recipient is deformed to be in a bent position by the operation of the actuator M1 and M2 (bed state diagram in FIG. 6, bed side view in FIG. 8 (b) See).

In addition, although the wire mesh is actually stretched on the surface of the connection floor part lla-lld of the bed frame 10 and the side members 12Ra-12Rd and 12La-12Ld, the following figures including this figure Here, in order to clearly show the configuration of the bed, the surfaces made of the wire mesh are omitted and only the frames of the connection floor parts 11a to 11d and the side members 12Ra to 12Rd and 12La to 12Ld are illustrated. In the present invention, the connecting floor portions lla to lld, and the side members 12Ra to 12Rd, and 12La to 12Ld are not limited to the surface configuration of the wire mesh, and these are connected to each other by connecting the plate members. Also, let's configure. In FIGS. 5 to 7 which are shown as operation diagrams, in order to clarify the operation of the bed, the illustration of a part of the configuration such as the side member support frames 24R and 24L is omitted.

Of the side members 12Ra to 12Rd and 12La to 12Ld, on the surface of 12Rc and 12Lc corresponding to the vicinity of the patient's thigh, an envelope-type pocket of approximately the same size as the 12Rc and 12Lc is disposed (see FIG. See bed profile in 8 (d)). Further, fan-shaped plates 13R and 13L (13R are not shown) are connected to the end portions of 12Rd and 12Ld which are below the knees of the cared person, and these are usually stored in the pockets of 12Rc and 12Lc. Then, when the bed frame 10 is deformed to the bending posture, the fan-shaped plates 13R and 13L are exposed from the pockets to support the knee portion of the care recipient.

The movable stage 20 has a rectangular frame structure with a center beam 21A, side beams 21R, 21 and two frames connecting both ends of these three frames in parallel. In the side beams 21R and 21L, as shown in the figure, the rollers 200, 201, 202, and 203 (203 is a bed frame 10, which can slide on the roller slide frame 300 of the fixed stage 30 along the y direction in the figure). Hiding below) is placed.

For the side beams 21R, 21L of the movable stage 20, each two bars 22R, 23R, 22 along the respective frames 21R, 21L, and 23L and connections 15 231R, 232R, 231L, 232L, force, Ladder-like 咅 J 咅 15 material support frames 24R and 24L are arranged. The area of the bars 23R, 23L where the side members 12Rb, 12Lb and the side member support frames 24R, 24L are in contact with each other is partially formed in a recess, into which the side member 12Rb fits (see the bed of FIG. 3). When the bed frame 10 is deformed to the bent position, it is designed not to interfere with the side members 12Ra, 12La and 12Rc, 12Lc and 12Rb, 12Lb in the thickness direction. Further, the frame 22R, 22L and the frame 21R, 21L are connected by the connecting rod B materials 236Ra, 236La, 236Rb, 236Lb, and by this connection, the bars 22R, 22L are fixed to the frame 21R, 21L while the shaft is fixed. It moves as a rotatable bar in the direction. And side member support frame 24R, If 24L rotates the bed plane in the vertical direction (z direction) around the rotation bars 22R and 22L, the side members 12Ra to 12Rd and 12La to 12Ld of the bed frame 10 are pushed up, so raise this. Can.

Here, FIGS. 2 (a) to 2 (c) are motion diagrams of the actuator of the schematic bed cross section in the vicinity of the movable plate 20 and the waist plate 11c of the bed frame 10. FIG. As shown in this figure, in the movable bed 20, in addition to the actuators M1 and M2 for deformation of the bed frame 10 described above, the connecting members 236Ra and 236La are symmetrical from the left and right direction of the center beam 21A, that is, from both sides in the y direction. Linear motion actuators M3R and M3L are disposed, and the shaft tips of these actuators M3R and M3L are connected to L-shaped members 235R and 235L that are fixed by hanging from the rotation bars 22R and 22L. . With this configuration, the actuator M3R and M3L are rotated about the axis of the L-shaped member ^ material 235R and 235L and no 23R, 23L force S rotation and 22R and 22L, and the side member support frame. 24R, 24 L Force S Rise from the bed horizontal plane and rise in the direction perpendicular to the bed horizontal plane (Operation diagram 2 (a) → (b) → (c)).

Stage bars 27R and 27L are provided on the lower surface of the side beams 21R and 21L, and are engaged with stage bar receivers 36R and 36L having a U-shaped cross section on the fixed stage 30 side. The stage bar receivers 36R and 36L have inverted L-shaped bumps inside along the width direction, and when the bumps are caught around the stage bars 27R and 27L, the movable stage 20 is vertically moved. Although fixed, when the movable stage 20 is inclined, either of the stage bars 27R, 27L on the side of the inclined stage is separated from the stage bar receivers 36R, 36L.

Here, FIG. 4 is a perspective view showing the configuration of the fixed stage 30. As shown in FIG. The fixed stage 30 is provided with a rectangular frame 31. The pair of short sides of the frame 31 is a sliding frame 300, so that the rollers 200,... Of the movable stage 20 can reciprocate on the frame 300. The two side beams 32R, 32L of the fixed stage 30 are slide groove members having a U-shaped cross section, and the slide grooves are arranged to face each other. The side beams 32R and 32L are each The ends of the support arms 354R, 356R, 354L, 356L connected with the first support 36R, 36S are reciprocably fitted. The support arms 354R, 356R, 354, and 356L are reverse L-shaped rotary arms 351R, 352R, 351L, 352L, whose one ends are connected to the side beams 32R, 32L. And horizontal links 353R and 353L are connected to 352L. Between the stage bar receivers 36R, 36L and the horizontal links 353R, 353L, diagonal grids M4R, 4L are arranged. Thereby, parallelogram mechanisms 35R and 35L to which the horizontal slide mechanism is applied are formed on the left and right sides of the fixed stage 30. In this parallelogram mechanism 35R, 35L, the rotary arms 351R, 352R, 351 and 352 move in a circular motion centering on the connecting part on the side beam 32R, 32L side, and the rotary arms 351R, 352R, 351L, 352L. Support arms 354R, 356R, 354 while being regulated, and each end of 356L Force beam 32R, 32 reciprocate inside, respectively, the support arms 354R, 356R, 354 and 356L swing in the vertical direction Then, the movable stage 20 and the bed frame 10 supported by the stage bar receivers 36R and 36L can be vertically moved from the left and right sides of the fixed stage 30. Therefore, in this turning support bed 2, it is possible to move up and down even in a narrow space and save space even when changing the posture by adopting parallel rollers 35R, 35L with rollers 200, ... It can be realized. If one of the above parallelogram mechanisms 35R and 35L corresponding to the side beams 32R and 32L is driven, the posture change from supine position to lateral position is performed. At the same time, the bed's high / low mechanism is realized.

The operation of each actuator M1, M2, M3R, M3L is controlled by the motor driver and CPU included in the control unit (not shown). For example, manual / automatic setting, program setting by carer by hand controller Drive settings can be made. In addition, the care recipient's own setting can be performed by providing an infrared type or corded wired wireless radio controller or a wireless remote controller.

1-2. Operation of the rollover support bed (conversion from supine position to left side recumbent position) The turning support bed of the above configuration is used by laying a mat on the bed frame 10. In the normal mode, as shown in FIG. 1, the connection floor parts 11a to 11d, the side members 12Ra to 12Rd, and 12La to 12Ld are set substantially in the horizontal plane.

When the user (here, a care giver as an example here) selects an item related to <supine position → left lateral position conversion in bending position> in the menu via the controller and executes this, first, the movable position is moved first The actuator M3L attached to the stage 20 is activated and the axis is extended. Then, the L-shaped member 235L and the bar 23L connected to the tip of the shaft rotate around the rotation bar 22L, and the side member support frame 24L rises from the bed plane and occurs in the direction perpendicular to the bed plane ( Fig. 2 (a) → (b) → (c), the state diagram of the side member 12La to 12Ld which has occurred vertically; Fig. 5 and the bed side view at this time; Fig. 8 ( c)).

Subsequently, the shaft tips of the linear motion actuators Ml and M2 attached to the center beam 21A of the movable stage 20 extend, and the L-shaped connecting members 211 and 212 allow the upper body plate 11a of the bed frame 10 and the thigh plates 11c is pushed up from the back side, and a bending posture in which the upper body is lifted up and knees is formed (a bed perspective view in a bending posture; FIG. 6, a bed sectional view at this time; FIG. 8 (a) → (b) )). Along with this, the side members 12La to 12Ld are also deformed in accordance with the connecting floor portions 1 la to 1 Id. At this time, the fan-shaped plate 13L is exposed from the pocket provided on the side member 12Lc, and supports the mat portion and the futon portion located at the knee portion of the care recipient (bed side view at this time; FIG. 8 (c) → (d).

Then, when the side member is raised by the above operation and the bending posture is adjusted, the actuator M4R on the side beam 32R side of the fixed stage 30 is operated, and the axis is extended. As a result, the oblique distance between the stage bar receiver 36R and the horizontal link 353R is separated, and the support arms 354R and 356R slide on the slide grooves of the side beams 32R and lift up, and the parallelogram mechanism 35R operates. At this time, the support arm 354R, 356R, ί 354, 356L L rotating arm 351R, 352R, or 351L, 352L by the circular motion of the right side of the movable stage 20 vertically Lift in the direction. Along with this, the right side of the movable stage 20 is raised to a position higher than the fixed stage 30, and the rollers 200 of the movable stage 20 roll on the roller slide frame 300, and the bed frame 10 is the side beam of the fixed stage 30. 32 L, that is, sloping in the left direction of the bed (bed state at the time of bed inclination; Figure 7). The preferable inclination angle at this time is, for example, in the range of about 30 degrees to 70 degrees with respect to the horizontal plane, for example, about 50 degrees.

According to such a modification of the bed frame 10, the cared person, in the posture change from the supine position to the lateral position, is in advance in the supine posture while keeping the bending posture of the upper body in the supine position / the knee raising position. While supported by lla to lld and side members 12La to 12Ld, the caretaker applies the hand and is well repositioned with the smoothness such that it rotates along the hand.

Therefore, in the first embodiment, since the care recipient can change the posture with the lightest bending posture, it is possible to easily change the posture, and the physical pain associated with the conventional posture change and the like. I can expect improvement in my mental anxiety.

In addition, in the first embodiment, since the care worker does not require manual labor that requires much labor for repositioning of the care recipient, the care person who has little experience must also appropriately reposition the care recipient. Can. Therefore, using the rollover support bed 2 of this embodiment, it is possible for the carer to concentrate on care that is meticulously.

3. On the movable bed mat (mat with fixture) of the present invention

Next, the movable bed mat 1 of the present invention will be described in detail. FIG. 9 is a configuration example of the turn support bed 2 and a movable bed mat used therefor. As shown in the figure, the movable bed mat 1 is provided with a fixture 100 to the waist plate l i b of the turning support bed 2 corresponding to the waist of the care recipient.

As shown in FIG. 10 (a), the fixture 100 has a configuration in which a total of four T-shaped cross-sectional convexes 102 are disposed on a plate 101. As shown in FIG. The convex part 102 is made of a hard rubber material, and the turn support bed 2's lumbar plate lib It fits in the gap of the mesh stretched on the surface and fixes the mat side and the bed side. According to the mat 1 having such a fixture 100, as shown in FIG. 10 when the bed is driven, the mat 1 is formed when the gear tension (FIG. 10 (b) → (c)) is formed. The upper and lower ends extend smoothly while being fixed well in the vicinity of the fixture 100. As a result, the movement of the movable bed effectively prevents the occurrence of positional deviation of the mat 1 (the occurrence of positional deviation in the thrust direction), and forms a smooth mat surface by utilizing the expansion of the mat. Is possible. The convex portion 120 can be detached from the mesh surface, which facilitates replacement of the mat 1 and maintenance of the movable bed 2 side.

Here, in the case where the extension of the mat is relatively small, the fixture 100 may be provided at a position other than the surface facing the floor l i b. Further, the position at which the fixture 100 is provided is not limited to the above position, and a plurality of positions may be provided.

In addition, the fixing tool is not limited to the above configuration, and may be another configuration (for example, using a magic tape for a floor having a flat floor surface, etc.) according to the material and configuration of the floor. Good.

1-4-Other matters

In the first embodiment described above, the bed configuration uses the parallelogram mechanism. The movable bed mat of the present invention is not limited to the bed configuration using the parallelogram mechanism, and the following may be applied. It may be applied to a movable bed of another configuration.

The turn support bed shown in Fig. 1 (a) has the linear motion actuator arranged vertically, and either the left or right side member is moved up and down using the vertical lift mechanism, thereby the floor on the movable stage. The part is inclined. The turning support bed has a pair of column-type linear motion actuators in a rectangular frame-shaped fixed stage, and a bed frame supported by a movable frame on this. The floor portion is constituted by the connection floor portion as in the first embodiment, and is connected by a plurality of joints respectively corresponding to the upper body, the hips, the thighs, and the knees of the non-carer. Is fixed to the floor frame-like movable frame It is done. The back of the floor is provided with a drive with an actuator mechanism for bending.

Side members are disposed on the column-type linear motion actuators. A storage groove is formed in the inside of the side member, and a pull-out side member which is divided in the longitudinal direction of the bed and connected to each other is accommodated therein. The side member is connected to the movable stage supporting the floor through the pullout side member. The pullout-type side member is urged in the direction of the storage groove by a tension spring or the like, and is automatically stored in the storage groove if the pulling-out force is weakened. According to such a care support bed, as shown in FIG. 11 (b), first, a bending posture is formed in the connecting floor when driving. Thereafter, one of the column type linear actuators is activated to lower the side member thereon. Along with this, one side of the movable stage is inclined, and the connecting floor is also inclined. Then, at the lower side of the inclined movable stage, the pullout side member is pulled out from the storage groove with respect to the connection floor, and the pullout side wall is relatively raised with respect to the connection floor, that is, connection The drawer-type side member is suspended from the floor, and the angle between the two is narrowed. At the same time, the side members rise up against the floor of the floor. As a result, the cared person can be supported by the pullout-type side member with the body side in the bending posture, and the posture can be well repositioned as in the first embodiment.

On the other hand, Fig. 12 is a diagram showing the configuration of another turn support bed.

The turning support bed can be used as a general bed, and is constructed by laying an air mat on which a plurality of air sacs are arranged on the bed surface. And, it is characterized in that air can be supplied / discharged independently to each air sac via air hose by using an air pump. The air hose has a valve, and the air pump and the control unit (not shown) control opening and closing, and the inflation and deflation of each air bladder are controlled. The air sacs are divided into upper body and waist (two layers of air sacs), thighs, below the knees, and both sides of the bed according to the joints of the carer's body, as an example. In this type of turn support bed, a cloth is usually used by laying on an air mat. Then, when changing the posture from the supine position to the lateral position of the carer, first expand the upper first air sac on both sides of the bed (Fig. 12 (a) → (b)). Then, the flexor is formed by tilting the air sac that hits the upper body 'waist in the longitudinal direction in the carer's waist in the longitudinal direction and expanding the air sac that hits the knee and below the thigh and knee (Figure 12 (c) and ( d)). Then, deflate the air sacs that hit either the left or right side wall, and expand the lower air sacs that hit the upper body and lower back, and do the posture change to the left lateral recumbence / right lateral recumbency with the flexion posture. Can be done (Figures 12 (e) and (f)).

In addition, although the example which used the general bed was shown here, the bed of the example of the composition is excellent in portability, and it is applied to various types of beds, and it is possible to use it on the floor such as on a tatami or carpet. There is also a merit that can be laid directly. Industrial applicability

The movable bed mat of the present invention described above can be used as a care support bed and a mat for a recovery bed.
