Description

Mat for movable bed {MATTRESS FOR MOVABLE BED}

The present invention relates to a mat placed on a nursing movable bed.

In general, a movable bed used for a body reversal support bed or the like tilts a part or the entire surface of a mat surface of a bed on which a patient is loaded to prevent the occurrence of pressure sores, the so-called bedsores of the user, the patient. It reverses and supports position conversion (refer to Unexamined-Japanese-Patent No. 6-14824). Most of these body-turning support beds take the mechanism which inclines toward the mat width direction in the flat state at the time of position conversion support.

However, when the movable bed is moved, the mat placed on the movable bed may be out of position and the patient's position may be out of the correct position. This problem, in addition to disturbing the normal driving of the movable bed, had room for improvement in terms of patient safety.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention is a movable bed mat attached to the bottom part of the movable bed which a bed surface can deform | transform, and the fixture which engages with a bottom part is provided in the mat surface facing the said bottom part. .

According to this configuration, since the mat is prevented from causing positional shift with respect to the bed surface when the movable bed is driven, the patient lying on the side of the bed may want to change position to a safe and correct posture, and also have a good face. This is promised.

Specifically, the movable bed may have a mesh formed at the bottom thereof, and the fastener may be configured to fit the gap between the meshes to fix the mat.

In this case, when the fastener is detachably attached to the bottom of the movable bed, it is preferable to replace the mat and to repair the movable bed.

The fastener is preferably disposed at a position corresponding to the waist of the user lying sideways on the mat on the mat surface, since the mat can be easily stretched and folded during bed operation.

Moreover, as an example of the movable bed applied to this invention, the said movable bed is a bottom part which can bend the bottom surface, the bending mechanism which forms the bending posture which includes at least any one of raising a body and raising a knee by bending a bottom part, and a bottom part An example is provided with an inclination mechanism for inclining the bottom surface laterally, wherein one of the bending mechanism and the inclination mechanism is operable in an operating state of the other mechanism.

1. First embodiment

1-1. Composition of body reversal support bed

1 is a perspective view showing a configuration of a body flip support bed 2 according to a first embodiment of the present invention.

The body flip support bed 2 has the structure which mounted the movable stage 20 on the fixed stage 30, and arrange | positioned the bed frame 10 on this.

 The bed frame 10 is divided into four joint parts including a back, a waist, a thigh, and a calf in accordance with the position of the body when the patient lies on the surface of the bed. Connecting bottom portions 11a to 11d are provided. In these connection bottom parts 11a-11d, the upper body board 11a, the waist board 11b, the thigh board 11c, and the calf board 11d are connected in the same order, respectively.

Since the waist plate 11b is directly attached and fixed to the movable stage 20 by welding or the like, the bed frame 10 does not come out of the movable stage 20. The side members 12Ra to 12Rd and 12La to 12Ld for supporting the side of the body of the patient are connected to the left and right sides of each connection bottom portion 11a to 11d, respectively. The upper body plate 11a and the thigh plate 11c of the bed frame 10 are linear actuators M1 and M2 disposed in the center beam 21a of the movable stage 20 (see bed top view in FIG. 3). Since the axis is connected to the L-shaped connecting members 211 and 212 through the operation of the actuators M1 and M2, the patient is deformed so as to be in a bent posture (the bed state of FIG. 6 is also shown in FIG. 8B). See bed side view).

In addition, although the wire mesh is actually covered on the surface of the connection bottom part 11a-11d and the side members 12Ra-12Rd, 12La-12Ld of this bed frame 10, each drawing below including the said drawing In order to clarify the configuration of the bed, only the frames of the connecting bottom portions 11a to 11d and the side members 12Ra to 12Rd and 12La to 12Ld are shown by omitting the surface made of the wire mesh. In the present invention, the connection bottom portions 11a to 11d and the side members 12Ra to 12Rd and 12La to 12Ld are not limited to the surface configuration of the wire mesh, but may be constituted by connecting the plate members themselves. In FIGS. 5-7 shown as an operation diagram, in order to make the operation | movement of a bed clear, the illustration of some components, such as side member support frames 24R and 24L, is abbreviate | omitted.

Envelope pockets of approximately the same size as those of 12Rc and 12Lc are disposed on the surfaces of the side members 12Ra to 12Rd and 12La to 12Ld corresponding to the vicinity of the thigh of the patient (Fig. 8 (d)). See bed side view]. Also, 12Rd and 12Ld corresponding to the calf of the patient are connected with fan-shaped plates 13R and 13L (13R not shown) at their ends, and they are usually accommodated in the pockets of the 12Rc and 12Lc. When the bed frame 10 is deformed into the bending position, the fan-shaped plates 13R and 13L are exposed from the pockets to support the knee portion of the patient.

The movable stage 20 has a rectangular frame structure by the center beam 21a, the side beams 21R and 21L, and two frames which connect the both ends of each of these three frames in parallel. As shown in the drawings, the side beams 21R and 21L have rollers 200, 201, 202, and 203 that can slide on the roller slide frame 300 of the fixed stage 30 along the y direction in the drawing. 203 is hidden under the bed frame 10].

The side beams 21R, 21L of the movable stage 20 are provided with two bars 22R, 23R, 22L, 23L and connecting portions 231R, 232R, 231L, and 232L respectively corresponding to each of these frames 21R and 21L. Ladder type side member support frames 24R and 24L which are formed are arranged. The areas of the bars 23R, 23L, which the side members 12Rb, 12Lb and the side member support frames 24R, 24L touch each other, are partially formed with recesses, and the side members 12Rb are inserted into the recesses. (See bed top view in FIG. 3), so that the side members 12Ra, 12La and 12Rc, 12Lc, and 12Rb, 12Lb do not interfere with each other in the plate thickness direction when the bed frame 10 is deformed into the bending position. It is designed. In addition, the bars 22R and 22L and the frames 21R and 21L are connected by the connecting members 236Ra, 236La, 236Rb and 236Lb, and the bars 22R and 22L are connected to the frames 21R and 21L by this connection. It is moved as a rotating bar rotatable in the axial direction in a fixed state. Then, when the side member support frames 24R and 24L rotate the bed plane to the vertical direction (z direction) around the rotation bars 22R and 22L, the side members 12Ra to 12Rd of the bed frame 10, 12La to 12Ld) is pushed up can cause this.

2 (a) to 2 (c) are schematic diagrams of the actuator operation of the bed section in the vicinity of the waist plate 11c of the movable stage 20 and the bed frame 10. FIG. As shown in the figure, in addition to the actuators M1 and M2 for the deformation of the bed frame 10, the movable bed 20 has a connecting member (from the left and right directions, i.e., both sides in the y direction) of the center beam 21a. 236Ra and 236La are symmetrically arranged linear actuators M3R and M3L, and L-shaped members 235R and axial ends of each of the actuators M3R and M3L suspended from rotating bars 22R and 22L. 235L). With this configuration, the actuators M3R, M3L extend the shaft so that the L-shaped members 235R, 235L and the bars 23R, 23L rotate about the axis of the rotation bars 22R, 22L, and the side member support frame. 24R and 24L arise from the bed horizontal plane and occur in a direction perpendicular to the bed horizontal plane (operation Fig. 2 (a)-(b)-(c)).

Moreover, stage bars 27R and 27L are provided in the lower surface of side beam 21R, 21L, and are fitted with stage bar support parts 36R and 36L which have a U-shaped cross section by the fixed stage 30 side. The stage bar support portions 36R and 36L have inverted L-shaped hooks therein along the width direction, and the movable stage 20 is fixed in the vertical direction by engaging the hooks around the stage bars 27R and 27L. However, any one of the stage bars 27R, 27L on the stage side side inclined at the time of inclination of the movable stage 20 is spaced apart from the stage bar support portions 36R, 36L.

4 is a perspective view showing the configuration of the fixed stage 30. The fixed stage 30 is provided with the frame 31 of rectangular shape. Then, the pair of short sides of the frame 31 is a roller slide frame 300, the rollers (200, ... ...) of the movable stage 20 can be reciprocated on the frame 300 have. Both side beams 32R, 32L of the fixed stage 30 are slide groove members having an inverted U-shaped cross section, and are arranged with the slide grooves facing each other. End ends of the support arms 354R, 356R, 354L, and 356L connected to the stage bar support parts 36R and 36L are inserted into the side beams 32R and 32L, respectively. Inverted L-shaped rotating arms 351R, 352R, 351L and 352L having one end connected to the side beams 32R and 32L are linked to the support arms 354R, 356R, 354L and 356L, and the rotating arms 351R, 352R and 351L are linked. And 352L, horizontal links 353R and 353L are connected. Further, actuators M4R and M4L are disposed at an angle between the stage bar support portions 36R and 36L and the horizontal links 353R and 353L. Thereby, parallelogram mechanism 35R, 35L which applied the horizontal slide mechanism is formed in the right and left sides of the fixed stage 30. As shown in FIG. In the parallelogram mechanisms 35R and 35L, the rotary arms 351R, 352R, 351L, and 352L are circularly moved about the connecting portions on the side beams 32R and 32L, and the rotary arms 351R, 352R, 351L, and 352L are rotated. Each end of the support arms 354R, 356R, 354L, 356L reciprocates in the side beams 32R, 32L, respectively, while the support arms 354R, 356R, 354L, 356L are vertically regulated. In this case, the movable stage 20 and the bed frame 10 supported by the stage bar bearing parts 36R and 36L can be elevated in the vertical direction from both the left and right sides of the fixed stage 30. Therefore, the body upside down support bed (2) can move up and down in a narrow space due to space saving, and also save space during body position conversion by employing the rollers (200, ...) and the parallelogram mechanism (35R, 35L). It is to be realized. When one of the parallelogram mechanisms 35R and 35L corresponding to each of the side beams 32R and 32L is driven, the position conversion from the supine position to the lateral position is performed, but the parallelogram mechanisms 35R and 35L are simultaneously driven. This realizes the high / low mechanism of the bed.

In addition, the operation of each actuator M1, M2, M3R, M3L is controlled by a motor driver and a CPU included in a control unit (not shown), respectively. Drive setting such as program setting can be performed. In addition, setting by the patient itself can also be performed by providing an infrared type or a corded or wireless remote controller with a cord.

1-2. Movement of the body upside down support bed (from supine to left supine)

The body upside support bed of the above structure is used on the bed frame 10 on the mat. In a typical embodiment, as shown in Fig. 1, the connection bottom portions 11a to 11d and the side members 12Ra to 12Rd and 12La to 12Ld are set in substantially horizontal planes.

When a user (here as an example, a nurse) selects and executes an item related to <conversion of the supine position to the left position of the bend position> in the menu, for example, an actuator (attached to the movable stage 20) M3L) is activated and the shaft is stretched. Then, the L-shaped member 235L and the bar 23L connected to the distal end of the shaft rotate about the rotation bar 22L, so that the side member support frame 24L arises from the bed plane, and is perpendicular to the bed plane. [Actuator operation also; Fig. 2 (a)-Fig. 2 (b)-Fig. 2 (c), the state diagrams of the side members 12La to 12Ld vertically generated; 5 and the bed side view at this time; (C) of FIG. 8].

Subsequently, the shaft end portions of the linear actuators M1 and M2 attached to the center beam 21a of the movable stage 20 are extended to pass through the L-shaped connecting members 21L and 212 to form the upper body plate of the bed frame 10. 11a) and thigh plate 11c are pushed up from the back side to form a bending posture of upper body raising and knee raising (bed perspective view in bending posture; 6, bed section at this time; (A) of FIG. 8 → (b) of FIG. 8]. At the same time, the side members 12La to 12Ld are also deformed to fit the connection bottoms 11a to 11d. At this time, the fan-shaped plate 13L is exposed from the pocket provided in the side member 12Lc, and supports the mat part and the bed part located in the knee part of the patient [bed side view at this time; (C) of FIG. 8 → (d) of FIG. 8].

When the side member raising and the bending posture are provided by the above operation, the actuator M4R on the side beam 32R side of the fixed stage 30 is operated to extend the shaft. As a result, the oblique distance between the stage bar bearing portion 36R and the horizontal link 353R is spaced apart, and the support arms 354R and 356R slide on the slide groove of the side beam 32R to lift the parallelogram mechanism. 35R is activated. At this time, the support arm 354R, 356R, or 354L, 356L lifts the right side of the movable stage 20 in the vertical direction by the circular motion of the rotary arm 351R, 352R, or 351, 352L. At the same time, the right side of the movable stage 20 rises to a position higher than the fixed stage 30, so that the rollers 200,... Of the movable stage 20 roll over the roller slide frame 300, and the bed The frame 10 is inclined to the side beam 32L of the fixed stage 30, that is, to the left side of the bed (bed state diagram at the time of bed inclination; Fig. 7). As a preferable inclination-angle at this time, it is the range of about 30 degrees-70 degrees with respect to a horizontal plane, for example, about 50 degrees.

According to such a deformation of the bed frame 10, the patient in the position change from the supine position to the lateral position, the connection bottoms 11a to 11d and the side members in a state of preliminarily raising the upper body / elbow in the supine position Supported at (12La to 12Ld), the nurse is position-positioned well by the smoothness of touching and rotating along the hand.

Therefore, in the first embodiment, since the patient can change the position to the least posture, the position change can be performed comfortably, and the improvement of physical pain and mental anxiety accompanying the position change as in the past can be expected. .

Furthermore, in the first embodiment, even the caregiver does not require manual labor for heavy labor to change the position of the patient, so that the inexperienced caregiver can appropriately perform the position change of the patient. Therefore, if the body upside support bed 2 of this 1st Embodiment is used, a caregiver can concentrate on nursing with such a fine detail.

1-3. About movable bed mat (mat with fastener) of this invention

Next, the movable bed mat 1 of this invention is demonstrated in detail. Fig. 9 is a configuration example of the body upside support bed 2 and the movable bed mat used therein. As shown in the drawing, the movable bed mat 1 includes a fastener 100 attached to the waist plate 11b of the body upside support bed 2 corresponding to the waist of the patient.

This fastener 100 has a configuration in which convex portions 102 having a total of four T-shaped cross-sectional structures are arranged on the plate 101 as shown in Fig. 10A. The convex part 102 is made of a hard rubber material, and fits in the clearance gap of the mesh covered on the surface of the waist plate 11b of the body upside support bed 2, and fixes the mat side and the bed side.

According to the mat 1 having the fastener 100 as described above, when the bed posture (Fig. 10 (b) + Fig. 10 (c)) is formed as shown in Fig. 10 during bed driving, the mat ( 1) The upper and lower ends extend smoothly in a state where it is well fixed around the fixture 100. Thereby, it becomes possible to form a smooth mat surface by utilizing the elongation of a mat, effectively preventing the occurrence of the position shift of the mat 1 (the occurrence of the position shift in the thrust direction) by the operation of the movable bed. Moreover, the convex part 102 is removable from a mesh surface, and the replacement | exchange of the mat 1 and the repair of the movable bed 2 side become easy.

Here, when the mat is relatively small in extension, the fastener 100 may be provided at a position other than the surface opposite to the bottom portion 11b. In addition, the position provided with the fixing tool 100 is not limited to the above-mentioned position, You may install in multiple numbers.

The fastener is not limited to the above-described configuration, and may be a different configuration (for example, using a magic tape for the bottom having a flat bottom) according to the material and configuration of the bottom.

1-4. Other matter

In the first embodiment, the bed configuration using the parallelogram mechanism is used. However, the movable bed mat of the present invention is not limited to application to the bed configuration using the parallelogram mechanism. do.

The body inversion support bed shown in Fig. 11A is arranged with the linear actuator in vertical position, and the left and right side members are lifted by using the lifting mechanism in the vertical direction, thereby lowering the bottom portion on the movable stage. It is tilted. The body reversing support bed arranges a pair of columnar linear actuators in a fixed frame of a rectangular frame shape, and on it a bed frame supported by a movable frame. Like the first embodiment, the bottom portion is composed of a connecting bottom portion, and is connected by a plurality of joints corresponding to the upper body, the waist, the thigh, and the calf of the non-nursing person, and the portion corresponding to the waist plate is the bottom frame type. It is fixed by the movable frame of. The back of the bottom part is provided with the drive part provided with the actuator mechanism for a bending posture.

The side member is disposed on the columnar linear actuator. The side member has an accommodating groove formed therein, and accommodates a pull-out side member which is divided in the bed length direction and connected to each other. The side member is connected to the movable stage which supports the bottom part via the said pull-out side member. The pull-out side member is pushed toward the storage groove direction by a tension spring or the like, and is automatically stored in the storage groove when the pulling force is weakened.

According to the nursing support bed having such a configuration, during driving, as shown in Fig. 11B, first, a bending posture is formed at the connecting bottom. Thereafter, one of the columnar linear actuators is operated to lower the side member thereon. In connection with this, one side of a movable stage inclines, and the connection bottom part also inclines. In the lower side of the inclined movable stage, the pull-out side member is pulled out from the receiving groove with respect to the connection bottom, and the pull-out sidewall is relatively raised with respect to the connection bottom, that is, the pull-out side member is suspended in the connection bottom. As a result, the angle between the two becomes narrow. At the same time, the side members are in a state of standing up against the bottom surface of the bottom part. As a result, the patient exerts an effect of supporting the body side part with the pull-out side member as it is in a bent posture, and the position is changed as in the first embodiment.

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

The body reversing support bed is a general bed available, it is configured by laying an air mat in which a plurality of air sacs are arranged on the bed surface. And it is characterized in that it is possible to supply / discharge the air independently for each air bag through the air hose using the air pump. A valve is attached to the air hose, and opening and closing is controlled by a control unit (not shown) together with the air pump to control expansion and contraction of each air sac. The bladder is here divided into upper body and waist (two stages of bladder), thigh and calf and both sides of the bed in accordance with the joint of the patient's body.

In a body upside support bed of such a configuration, it is usually used by laying a blanket on an air mat. Then, when the position of the caregiver is changed from the supine position to the lateral position, first, the air sacs of the upper first stage of both sides of the bed are inflated (FIG. 12 (a)-FIG. 12 (b)). Then, the postures in contact with the upper body and waist of the caregiver are inclined in the longitudinal direction, and the inflation posture is formed by inflating the sacs in contact with the thigh and the calf with the knee as the top point (Figs. 12 (c) and 12). (d)]. Then, by contracting the bladder that touches either side of the left or right side, and expanding the bladder of the lower second stage that contacts the upper body and the waist, the positional change to the left and right and right and left can be performed like the bending posture (Fig. 12 ( e) and FIG. 12 (f)].

Moreover, although the example using a general bed was shown here, the bed of the said structural example is excellent in portability, and it has the advantage that it can be directly attached to the floor, such as on a tatami mat carpet, besides the application to various kinds of beds.

The above movable bed mat of the present invention can be used as a mat for nursing support beds and reclining beds.
