Description

  The present invention relates to a multi-purpose bed apparatus provided with a function for nursing in a person being treated and cured, a function for care for a care recipient, and a function for physical care and rehabilitation in a healthy person.

  People who are in need of care for patients who are being treated for injuries or illness, or who need care or care recipients (hereinafter abbreviated as “caregivers”) have a long life on the bed, so-called care. Nursing care activities are often carried out in the living conditions on the bed. For this reason, for example, in order to reduce the burden on nurses and care workers (hereinafter abbreviated as nurses, etc.) for nursing and care, for example, a state where the upper body is raised It is well known that a bed having a convenient structure and function such as a structure that supports the bed and a structure that enables defecation while lying on the bed has been devised and used.

  The inventor of the present case has developed various types of bed apparatuses utilizing the experience of medical treatment life, and has successively proposed some of the results. For example, Japanese Patent Application Laid-Open No. 2003-79694 is a device that enables a shower on a bed, and Japanese Patent Application Laid-Open No. 2009-72321 is a device that facilitates excretion on a bed. Japanese Unexamined Patent Publication No. 2009-82388 makes it possible to wash the body in addition to excretion on the bed. Products that implement these inventions are well received.

  However, despite the common purpose of nursing and nursing beds, there are many structural differences due to differences in the requirements of nurses and care workers, which makes the usability slightly different and confusing There was a problem that there was something. For a common purpose, if there is a bed having a common structure, there is no single bed that can respond to a plurality of usage forms.

  The present invention has been made paying attention to the above points, and its object is to provide a multi-purpose bed apparatus that can cope with a plurality of usage forms with a single bed. Another object of the present invention is to provide a multipurpose bed apparatus.

  As a means for solving the above-mentioned problems, the present invention relates to a bed apparatus that can be used for various purposes as a healthy person or as a care recipient, and includes left and right side frames and front and rear connecting members for connecting them. The bed body has a structural strength that bears the entire load including the cared person, equipment and accessories, and the front body side is positioned on the upper body side of the cared person to raise or lift the upper body side. An upper movable floor supported by a point and its driving means, and a lower movable floor and its driving means which are positioned on the lower body side of the care recipient and supported at a plurality of points in the front and rear so as to raise and lower the lower body side. It is equipped.

  The apparatus of the present invention is a bed apparatus that can be used for various purposes as a care recipient or as a healthy person with a single bed. For this purpose, it is located on the upper body side of the cared person and has an upper movable floor supported at multiple points in the front and rear to raise or lift the upper body side, and is located on the lower body side of the cared person And a lower movable floor supported at a plurality of front and rear points so as to raise and lower the lower body side. This is intended to make it easier for the care recipient to take the posture necessary for life on the bed.

  The upper movable floor has left and right floor frames, and the left and right rollers are rotatably arranged between them, with a slight gap between them, and the lower movable floor is composed of left and right floor frames. It is desirable that a plurality of band plate members in the front-rear direction are arranged with a space left and right between them. The roller makes it easy to move the care recipient to a position convenient for hair washing, for example, and to adjust the height of the head. Moreover, the roller in the left-right direction and the belt-like member in the front-rear direction are useful for water treatment in the shower operation.

  The upper movable floor is driven by a link arm pivotally supported at the front of the bed body, the upper movable floor pivotally supported at the rear end of the link arm, and the upper movable floor. It has a rotary arm that supports the floor at the front, and a lift arm that is pivotally supported by the link arm in the vicinity of its pivot point, and the rotary arm and lift arm are driven by a single drive mechanism. Is desirable. The above configuration is one effective means that makes it possible to easily tilt the upper drive floor and raise it without tilting.

  The lower movable floor is composed of two front and rear parts connected at an intermediate hinge part, the front and rear parts are provided so as to be bendable, and are provided with a raising and lowering mechanism for individually raising and lowering the front and rear parts as driving means. It is desirable. With this configuration, the lower back is supported. It becomes possible to choose to weaken the support, and it is possible to prevent congestion, reduce floor rubbing, and improve blood flow.

  The bed main body can be configured such that the front frame is detachable at least at the front end portions of the left and right side frames. By making the front frame removable, it is possible to place a hair-washing wagon etc. directly under the head of the cared person during hair washing work (in that case, the cared person can move the upper movable floor It is assumed that the position of the head is moved by the roller so that the head comes out from the front end of the bed body). At the time of use, the cared person or the like lies on the upper movable floor and the lower movable floor, but at that time, they can also lie directly or lay down with mats.

  One of the features of the multi-purpose bed apparatus of the present invention is that the direction in which the bed is used can be freely determined without strictly defining the pillow side (front part) and the foot side (rear part). There is. Accordingly, in the present invention, the front equal upper body side equal pillow side or the rear equal lower body side equal foot side is a positional relationship in a standard method of use, or for convenience of explanation. Due to the above features, in the present invention, the movement applied to the upper body during standard use can be applied to the lower body by inverting the posture, and conversely, the movement applied to the lower body during standard use can be applied to the posture. It can be flipped and added to the upper body.

  Since the present invention is configured and operates as described above, one bed can be used for a healthy person or a cared person, and can be used for a plurality of usage forms and can be used for various purposes. An advantageous effect that a simple bed apparatus can be provided. In addition, according to the multipurpose bed apparatus of the present invention, it includes daily life such as eating and drinking, exercise of stretching and floating, and vertical movement of legs, etc., in a cared person who mainly lives on the bed. Implementation of rehabilitation, excretion treatment, washing only the buttocks, washing the hair or the entire body, increasing blood flow, preventing congestion and edema, preventing bedsores, and feeling refreshed by extending limbs while lying in bed Can be obtained.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 is a front view showing an example of a multipurpose bed apparatus 10 according to the present invention, and 11 shows a bed body. The bed main body 11 has left and right side frames 12 and 13 extending in the floor direction, a plurality of coupling members 14 for connecting the left and right side frames 12 and 13, and front and rear ends of the side frames 12 and 13 corresponding to the four corners for supporting the bed. The connecting member 14 is provided in at least two front and rear positions (see FIGS. 2 and 3). Moreover, since the drive mechanism 20 of the upper movable floor 21 mentioned later is arrange | positioned among them, although not shown in figure, the attachment structure part bears the role which couple | bonds the left and right side frames 12 and 13. .

  A front frame 17 and a rear frame 18 are detachably attached to the front leg column portions 15 and 15 ′ and the rear leg column portions 16 and 16 ′ by inserting respective lower portions from above. The front frame 17 and the rear frame 18 have the same shape and the same size, have no distinction between the front and the back, and are provided in a fence shape with good ventilation for the purpose of hanging wet towels and the like. Furthermore, by being removable, it is possible to get on and off the stretcher from the front and back rather than from the side of the bed, and for convenience such as washing hair. Reference numeral 19 denotes a wheel shown as a caster, which is provided at the lower part of all the pedestal portions 15, 16, 15 ', 16' and includes a brake or a stopper. However, the wheel 19 can be removed and replaced with a pad-like member (not shown), so that the wheel 19 can be converted from a movable type to a stationary type bed.

  In the bed main body 11 having the above-described configuration, an upper movable floor 21 that is mainly located on the upper body side and a lower movable floor 37 that is mainly located on the lower body side are disposed as portions forming the floor. The upper movable floor 21 has left and right floor frames 21l and 21r, and the rollers 22 in the left and right direction are arranged in a dense manner with a slight gap therebetween so as to be rotatable between them. Can be moved up and down by rotating the shaft as a pivot, and the link arm 25 can be moved up and down on the side frames 12 and 13 with the arm front 24 as a pivot. The link arm 25 is pivotally supported by the rear end portion of the upper movable floor 21 at the rear end portion (see FIG. 2). The roller 22 has a central portion 22a having a small diameter, and when the protrusion of the spinal column is conspicuous on the back of the cared person, the roller 22 can receive it and avoid conflict. The link arm 25 is set shorter than the upper movable floor 21.

  The drive mechanism 20 of the upper movable floor 21 has an electric motor that is a power source 26 and a speed reducer 27 that decelerates the rotational output thereof, and is thus configured as a drive means by the electric motor. The speed reducer 27 has a configuration in which the rotational output is decelerated by a multistage speed reduction mechanism and a strong torque is obtained to push up the upper movable floor 21. The speed reducer 27 in the example of FIG. 4 has 10 speed reduction gears consisting of a to j, and reduces the rotational output of, for example, 1500 rpm to about 6 rpm. In FIG. 4, a to j represent gears, and the portions surrounded by solid lines are integrated, for example, a and j are one gear, b to h and i are two large and small gears. It represents what is united. The gear a is fixed to one shaft 28, but the other gears c, e, g, i and the gears b, d, f, h, j of the other shaft 29 are not fixed. , The shafts 28 and 29 are idle. The gear l meshing with the gear d takes out the rotation of the high speed medium torque (for example, a reduction ratio of about 8: 1), and the gear m meshing with the gear h takes out the rotation of the low speed super large torque (for example, the reduction ratio of about 128: 1). The gear k is set to take out a rotation of a large torque in the middle (for example, a reduction ratio of about 32: 1). The above reduction ratio is an example, and should be changed depending on the motor output and electric power. A rotating handle 30 for manual operation is attached to the shaft 28.

  The output of the speed reducer 27 is taken out by the gear k at an appropriate gear stage and used to raise and lower the link arm 25. That is, the pin 31 is planted on the side surface of the gear k, the lifting arm 33 pivotally supported at the upper end 32 is suspended from the link arm 25, and the pin 31 is engaged with the engaging portion 34 at the lower end. It is provided so that engagement is possible. In addition, the raising / lowering arm 33 is urged | biased by the said engagement direction by the unauthorized means which is not shown in figure. The output of the speed reducer 27 is also used to raise and lower the rotary arm 35 for raising and lowering the upper movable floor. The rotating arm 35 is attached to the gear i at the final stage of the speed reducer 27 at the base, and supports the upper movable floor 21 on the lower surface by a roller 36 attached to the tip.

  The lower movable floor 37 located on the lower body side has left and right floor frames 37l and 37r, and a plurality of strip plate members 38d in the front-rear direction are disposed between them with a space left and right between them. It consists of two front and rear portions connected at the portion 38c, and the front and rear portions 38A and 38B are provided so as to be bendable. The front portion 38A is responsible for the thigh portion, and the rear portion 38B is responsible for the portion below the knee, and is pivotally supported by the left and right floor frames 37l and 37r at the front end portion 39.

  As shown in FIGS. 2 and 5, the lower movable floor 37 includes elevating mechanisms 40 </ b> A and 40 </ b> B for individually elevating and lowering the front and rear portions 38 </ b> A and 38 </ b> B as driving means. Each elevating mechanism 40A, 40B is provided with push-up levers 43, 44 attached to the side frame 12 by shafts 41, 42 and push-up handles 45, 46 for operation thereof. Each push-up lever 43, 44 is a small roll 43a. 44a are in contact with the lower surfaces of the front and rear portions 38A, 38B. The lower movable floor 37 has a slat-like structure that can be easily cleaned.

  In the figure, 47l and 47r are mainly front drop prevention fences for the upper body side, 48l and 48r are mainly rear drop prevention fences for the lower body side, and the upper movable floor 21 has left and right floor frames 21l and 21r and a lower movable floor 37. The left and right floor frames 37l and 37r are detachably provided by being inserted from above. These front drop prevention fences 47l, 47r, 48l, 48r have an arm extension space at the bottom so that the arm of the care recipient can be extended to the left and right. And the pillow leg insertion port 49 which attaches the detachable pillow 50 is formed in the front part and the rear part of the bed main body 11, Moreover, it is comprised so that the front frame 17 can be removed and the hair-washing wagon 51 can approach to a bedside. Yes. 52 is a defecation container part, which is disposed below the lower movable floor 37 and used.

  Next, the operation of the multipurpose bed apparatus 10 of the present invention configured as described above will be described. In FIG. 6 and subsequent figures, there is no mat or cushion between the multi-purpose bed apparatus 10 of the present invention and the user, but this is only described for convenience of explanation and is necessary. As mentioned before, sheets, mats, cushions and the like can be used as mats depending on the situation. The mats are prevented from coming off from side to side and from front to back by rising of the side frame portion of the bed body, a removable pillow or a stopper instead thereof, and a stopper 38d provided at the rear portion 38B of the lower movable floor 37. .

  Here, supplementing the description of the form of the mats, it is better to use a mat that is divided into a plurality of sheets rather than a single-sheet structure, and an example thereof is shown in FIG. Although the mats are partially sag by use and the comfort is impaired, by using the split type, only the mat part where the sag is generated can be replaced to maintain the comfort. To correct the misalignment between the body and mats, turn it upside down and move the split part to the left or right half, and for daily excretion, shower washing, and hair washing, only the mat part at the relevant location. Can be removed. 17A shows the mats 53 having a four-divided structure in the upper, lower, left, and right sides, B shows the mats 54 in an eight-divided structure in which the upper and lower sides of A are further divided into two parts, and C shows the mats 55 having a structure divided into six only in the vertical direction. Therefore, these mats 53, 54 and 55 are best made of sponge having a thickness of several centimeters. As for the hardness of the sponge, it is desirable to prepare a soft one to a hard one, and depending on the purpose, a futon type containing so-called cotton can be used. In any of the mats, the mat portions may be separated and not connected.

  FIG. 6 shows a normal sleeping posture in which both the upper movable floor 21 and the lower movable floor 37 are substantially horizontal and in the same plane, and there is no distinction between a care recipient and a healthy person. Even if the cared person or the like P where the protrusion of the spinal column is remarkable takes the posture of lying on the back, the protrusion is received by the dents of the central portion 22a of the large number of rollers 22, so that there is no feeling of pressure or pain. That's it. The weight of the upper body of the care recipient P is distributed and supported by a number of rollers 22, and is added as an appropriate acupressure effect to the bases of the ribs connected to both sides of the spinal column, thereby accelerating blood flow. The state shown in FIG. 6 is also a working posture for cleaning the lower body after excretion.

  FIG. 7 shows that the upper movable floor 21 is slightly raised while being substantially horizontal by the operation of the lifting arm 33 and the rotating arm 35, and the rear portion of the lower movable floor 37 is lifted by the operation of the rear lifting mechanism 40B. A space S is easily formed between the back of the thigh or the back of the calf. This releases the muscles of the lower body in the above part from the pressure, so that it is easy to form a space between the bottom of the buttocks and the upper surface of the floor, especially when the cared person P is a care recipient, and the diaper is removed and replaced. Make it possible to carry out work easily.

  FIG. 8 shows that the upper movable floor 21 is raised to a relatively shallow angle by the operation of the rotary arm 35 to slightly raise the upper body of the cared person P, and the lower movable floor 37 remains as in FIG. The purpose is to obtain a comfortable sleeping posture. Since the upper movable floor 21 is in a posture to stand up with a shallow inclination and force can be easily applied to the abdomen, it is suitable for the care recipient P to perform excretion, and is also suitable for subsequent cleaning and wiping work. If the upper movable floor 21 is further raised, the cared person P will be in a posture like sitting on a chair, and will be in a state of use suitable for eating and drinking.

  FIG. 9 shows that the rear part 38B of the upper movable floor 21 and the lower movable floor 37 are slightly raised so as to be substantially horizontal and flush with each other, and the front part 38A of the lower movable floor 37 is a front lifting mechanism 40A. As a forward tilted state by the operation of, a dent that accepts the bulge of the buttocks is made to avoid weight compression. As a result, the burden on the lower back (pelvis) can be reduced and recovery from fatigue and reduction or prevention of lower back pain can be expected. Furthermore, the sleeping posture is almost horizontal and the toes are pushed up from the hips, thereby promoting blood flow in the lower body. The above action can be expected in the same manner for the care recipient.

  FIG. 10 shows that the upper part of the upper movable floor 21 is raised to a shallow angle from the state of FIG. 9 to slightly raise the upper body of the cared person P, avoiding pressure on the buttocks and lower back. And it is a posture that can obtain peace of mind. In particular, in the cared person P, the portion 38A in front of the lower movable floor 37 that is in a depressed state eliminates or remarkably reduces body weight, so that the same comfort as in a healthy person can be obtained. .

  FIG. 11 shows the upper movable floor 21 from the state of FIG. 10 such that the upper part of the upper part of the cared person P is slightly warped so that the front part descends to a shallow angle. It is possible to obtain a posture in which the curved portion is pushed up from the back and warped and stretched against the waist. This can be expected to reduce or prevent lower back pain, and can provide comfort by enhancing the blood circulation in the upper body and stretching the back and pelvis. In this state, it is possible to obtain the effect of loosening the muscles of the back and the effect of enhancing blood flow by shifting the position of the back on the roller 22 without using the mats, and changing the position. In particular, in the case of a bedridden cared person P or the like, it is optimal for making muscles of the whole body flexible.

  FIG. 12 is the same state as FIG. 6 and is not particularly necessary for a healthy person, but the mat is removed and a shiatsu effect on the back muscles can be obtained by a large number of rollers 22 to prevent congestion and recover from fatigue. You can expect. However, for the cared person P or the like, the hair-washing wagon 51 can be placed on the pillow and receive a hair-washing service in this posture. That is, the front frame 17 of the bed main body 11 is removed, and the cared person P supports the pillow 50 by placing the back of the neck on the pillow 50, so the nurses do not need to support the weight of the cared person P head. After the body of P such as the cared person is placed at an appropriate position by the roller 22, it is possible to sufficiently engage in washing the hair while ensuring its own work position and posture. Therefore, the hair can be washed with almost no restrictions. However, this is a situation that cannot be expected of those who live on a conventional bed.

  FIG. 13 is a sleeping posture in which the head portion comes to the rear portion of the sleeping posture in the normal usage method shown in FIG. A new mood can be obtained from the difference between the contact sensation given from the roller 22 and the contact sensation given from the sword shape of the front and rear portions 38A, 38B of the lower movable floor 37. Even in this state where the front and rear positions are reversed, the rear frame 18 of the bed main body 11 is removed, and the cared person or the like P places the back of the neck on the pillow 50 and supports it, and also arranges the hair washing wagon 51, as shown in FIG. The hair can be washed in the same way, and the whole body can be washed by shower.

  FIG. 14 shows that all operations such as ascending and descending or changing the angle with respect to the leg portion, the main portion, the back portion and the like can be performed in the same manner even in the state of reverse use. In FIG. 14, the back is lifted almost in parallel by the lower movable floor 37 while maintaining a normal sleeping posture, and it is possible to experience a posture that cannot be obtained by the usage method of FIGS. 6 to 12.

  FIG. 15 shows a posture in which the front part 38A of the lower movable floor 37 is lowered and the rear part 38B is raised to lower the waist of the cared person P, and the upper movable floor 21 is tilted. The leg can be lifted larger than the previous examples, and the congested state of the entire leg can be alleviated. Although healthy people are also effective in recovering leg fatigue, blood flow tends to drop to the head, and supervision that takes this into account is necessary.

  Furthermore, in the multipurpose bed apparatus of the present invention, the bed main body 11 can be tilted, and by combining this with the above-described operation, a more varied operation can be created. FIG. 16 shows an example thereof, and shows a state in which the rotating arm 35 is rotated counterclockwise opposite to the above and the roller 36 is pressed against the floor F and the front portion of the bed main body 11 is pushed up. As a result, the entire body can take a posture inclined from the head to the foot at the same angle (in this case, needless to say, the wheel 19 is fixed by a brake or a stopper), for example, a person with hypotension It is effective in preventing dizziness that tends to occur. The above operation can be automatically performed by the controller 56, and can also be manually operated by the handle 30.
