Description

  The present invention relates to an oscillating nursing bed apparatus that can easily prevent a care recipient from rubbing the floor, and more particularly, to an oscillating nursing bed apparatus that can be driven by the nursing person himself / herself.

  The present inventor has been unable to sleep on his back almost 20 years ago, and cannot sleep unless he is always left or right sideways. After that, when I slept on the bed about 6 years ago, I suddenly thought that it would be the same as hitting the bed if I tilted the bed to the left and right, and I immediately made a prototype and tried it. As a result, I succeeded.

At first, I thought that the bed would not be effective unless it was tilted by 80 to 90 degrees, but it turned out that if the bed was tilted around 30 degrees, the effect would be the same as if it was turned over while repeating the experiment. It was. In addition, it was found that the time required for the bed to tilt back and forth and return to the original position is approximately 5 minutes.
When the present inventor heard in the hospital, in order to prevent bedridden patients from rubbing the floor, it was said that a few nurses are turning over every 3 hours.
The present invention can eliminate such a burden on a caregiver and is very useful for preventing floor rub of a care recipient such as a bedridden patient.

By the way, what was disclosed by patent document 1 is conventionally known as a bed apparatus for care which makes a care receiver turn over, for example.
This nursing bed apparatus is provided with lift cylinders under the left and right portions of the lift bed on which the mats are laid. The lift bed is lifted horizontally by simultaneously raising the left and right lift cylinders, and the toilet bowl is placed under the lift bed. In addition, the right and left lifting cylinders are lifted by only one side, and the lifting bed is tilted sideways so that the care recipient is turned over.

However, the known nursing bed apparatus described in the above-mentioned patent publication has a problem that a hydraulic pump or the like for swinging the bed is indispensable, which increases production costs and cannot be used in a place without a power source. For this purpose, it is conceivable to provide a crank at the end of the bed frame and swing the bed manually, but this causes a new problem that the bed cannot be swung unless the caregiver is accompanied. End up.
SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an inexpensive care bed apparatus that can be used in a place where there is no power source and can be prevented from being rubbed by the care recipient by tilting the bed by himself without the caregiver being accompanied. It is in.

  As a result of earnest research on a technique capable of overcoming the above-described problems of the above-described conventional technology and realizing the above-described object reliably, the present inventor has the following summary configuration. The present invention has been conceived.

That is, the swing type nursing bed apparatus of the present invention supports a head support base for supporting the cared person's head, a torso support base for supporting the cared person's torso, and the care receiver's legs. Leg support bases, and head side walls that are erected on both side ends of each of the support bases and support the head of the cared person in a state where the head support base swings obliquely laterally, A torso side wall that supports the torso of the cared person in a state where the torso support base swings obliquely laterally, and supports the leg of the cared person in a state in which the leg support base swings obliquely laterally A bed having leg side walls; a base that supports the bed so as to be swingable laterally around a horizontal axis extending in the longitudinal direction; and the horizontal axis extending around the bed in the longitudinal direction it comprises a swing mechanism for swinging the YokoMuko, the swing handle position adjusting mechanism, to the rocker Is arranged within the reach of the cared person's hand and swings together with the bed and swings when the cared person's human power is input, and from the swing handle, a transmission mechanism and a speed reduction mechanism der is, the swing handle position adjusting mechanism having a bed driving mechanism for swinging the lateral direction of the bed are input rotation through the said swing handle, to adjust the position relative to the bed It is characterized by being.

  According to the swing type nursing bed apparatus of the present invention, the head support base, the trunk support base, and the legs of the bed supported by the base so as to be swingable in the horizontal direction around the horizontal axis extending in the longitudinal direction. With the support platform supporting at least the head, torso and legs of the cared person lying on his / her back on the bed, the swinging mechanism moves around the horizontal axis extending the bed in the longitudinal direction. Since the head support base, the trunk support base and the leg support base are tilted to the left and right, for example, by about 30 degrees, they are cared in the same way that the cared person turns over. This has the effect of moving the person's pressed part to the opposite side, thereby effectively preventing the care recipient from rubbing the floor. Of course, the cared person may actually turn over by helping the bed tilt.

  In addition, according to the swing type nursing bed device of the present invention, when the bed is swung and the head support base, the trunk support base and the leg support base are inclined sideways, both sides of the head support base are The side wall of the head standing at the end supports the head of the cared person who lies on his back on the bed, and the side wall of the trunk standing on both sides of the torso support base lies on his back on the bed Since the side wall of the leg that supports the to-be-cared person's torso and the leg side walls that are erected on both sides of the leg support base supports the leg of the cared person who lies on his / her back on the bed, The caregiver can tilt the bed with confidence without fear of falling off the bed.

According to the swing type nursing bed apparatus of the present invention, the cared person who lies on his / her back on the bed grabs the swing handle that swings with the bed and is placed within the reach of his / her hand. When rotated, the bed drive mechanism receives rotation from the swing handle that receives the human power of the cared person and rotates through the transmission mechanism and the speed reduction mechanism to swing the bed laterally, such as a hydraulic pump. Because it does not use a swing mechanism, the care bed device can be used in a place without a power source and can be manufactured at low cost, and even if the caregiver is not accompanied, the care recipient can tilt the bed by himself to prevent floor rubbing can do.
Further, according to the swing type nursing bed apparatus of the present invention, since the swing handle position adjusting mechanism for adjusting the position of the swing handle with respect to the bed is provided, even if the cared person using the bed changes The handle can be easily arranged at a position that can be reached in accordance with the extension and physique of the cared person.

  In the swing type nursing bed apparatus according to the present invention, the head support base and the trunk part support base are raised with a horizontal position centered around an end near the leg part support base of the trunk part support base. It is provided with a rising mechanism that swings between positions, and the rising mechanism is disposed within the reach of the cared person's hand and swings together with the bed, and the cared person's human power is input and rotated. And a rising drive mechanism that receives rotation from the rising handle via a transmission mechanism and a speed reduction mechanism and swings the head support base and the trunk support base. preferable.

  According to such a configuration, when a cared person who lies on his / her back on the bed grabs the handle for getting up and is swung together with the bed and is rotated by the arm, the rising drive mechanism is The head support base and the trunk support base are supported by the rotation of the rising handle, which is rotated by inputting the human power of the cared person, via the transmission mechanism and the speed reduction mechanism, and the leg support of the trunk support base. Since it swings between the horizontal position and the rising position around the end near the platform, it can be used in places where there is no power supply, and the care bed device can be used at low cost because it does not use a hydraulic pump, etc. Yes, even if the caregiver is not attending, the care recipient can raise the bed's head support and torso support and tilt it horizontally to prevent floor rubbing. Rukoto can.

  In the swing type nursing bed apparatus of the present invention, the transmission mechanism may be a link mechanism or a gear mechanism having a transmission shaft that rotates independently of the bed swinging around a horizontal axis extending in the longitudinal direction. The transmission shaft with a universal joint may transmit the rotation from the handle to the bed drive mechanism or the rising drive mechanism on the base side. However, the transmission mechanism is a flexible, highly twisted wire in a flexible sheath. A flexible shaft containing a transmission shaft such as this is preferable because the rotation from the handle can be transmitted to the bed drive mechanism or the rising drive mechanism on the base side with a simple configuration.

Furthermore, Oite the swing type nursing bed apparatus of the present invention, the handle for the rising and comprises a rising handle position adjusting mechanism for adjusting the position relative to the bed, and the caregiver changes to beds However, it is preferable because the handle can be easily arranged at a position where the hand can reach in accordance with the extension and physique of the care recipient.

  Furthermore, in the swing type nursing bed apparatus of the present invention, the rising handle of the rising mechanism is supported at a predetermined position with respect to the bed and is disposed within a reach of the cared person's hand. Since the handle position adjusting mechanism that adjusts the position of the rising handle with respect to the bed and the flexible shaft of the transmission mechanism can be omitted, the configuration of the nursing bed device can be further simplified. It can be manufactured at a lower cost.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing an embodiment of the swing type nursing bed apparatus according to the present invention, and FIG. 2 is a plan view showing the swing type nursing bed apparatus of the above embodiment, as seen from the sole side of the cared person. FIG. 3 is a side view showing the center part of the swing type nursing bed apparatus of the above embodiment, and FIG. 4 is a trunk support base and legs of the swing type nursing bed apparatus of the above example. Sectional drawing which shows the cross section in the position between support stands, FIG. 5: is sectional drawing in the position similar to FIG. 4 which shows the rocking | fluctuation type nursing bed apparatus of the said Example in the state which the bed inclined sideways. 6 is a side view at the same position as in FIG. 3, showing the swing type nursing bed apparatus of the above embodiment in a state where the head support base and the trunk support base are obliquely raised. In the figure, reference numeral 1 is a bed extending in a substantially horizontal direction, 2 is a rectangular frame-shaped base, 3 is a gate-type support erected on both short sides of the base 2 Reference numeral 4 denotes a support shaft fixed to both ends of the bed 1 in the extending direction so as to support the bed 1, and reference numeral 5 denotes a support shaft 4 which is rotatably supported to extend the bed 1 in its longitudinal direction. Bearings provided at the upper end portion of the support column 3 so as to be swingable in the horizontal direction around the horizontal axis are shown. Moreover, the code | symbol P shows a care receiver.

  The bed 1 here has two girders 6 that are connected by a plurality of beams to form a ladder-like rocking table, and on the two girders 6 on both outer sides of the girders 6. A trunk floor plate 8 serving as a trunk support base supported by the two square pipes 7 positioned at is placed and placed. In this embodiment, the torso floor plate 8 extends under the head of the cared person P.

  9 is a trunk side plate as a trunk side wall projecting upward from the left end of the trunk floor plate 8 when the bed 1 is viewed from the sole side of the cared person P toward the head. The side plate 9 is shorter than the trunk floor plate 8 and is formed in a state where a part on the pillow side is opened. Also, a trunk side plate 10 as a trunk side wall shorter than the trunk floor plate 8 is projected upward at the right end portion of the trunk floor plate 8, and the trunk side plate 10 is similarly located on the pillow side. Part is opened. The reason is that when the trunk side plates 9 and 10 are formed with the same length as the trunk floor plate 8, the cared person P enters the box and feels very cramped. In the present embodiment, in order to solve the above problems, the trunk side plates 9 and 10 are shortened, and a gap is formed between the trunk side plates 9 and 10 and the head side plates 21 and 22 described later. It is opened sufficiently so that the cared person P can get his arm out of the gap.

  In addition, a leg floor plate 11 as a leg support is spanned and fixed on the two girders 6 on the leg side of the trunk floor plate 8. A leg side plate 12 as a leg side wall protrudes upward. Here, each of the trunk side plates 9 and 10 has a long hole extending in the lateral direction of the bed 1 and is fixed to the trunk floor board 8 with a bolt 13 passing through the long hole.

  Here, the rising mechanism supports the rising handle 81 at a predetermined position with respect to the bed 1 by directly coupling the rising handle 81 to the input shaft of the speed reducer 83 provided on the beam member 31, and the rising handle 81. An umbrella-shaped hand placement member 87 is provided to make it easy to grasp the handle 81 for raising, and a support shaft 85 is drivingly coupled to the output shaft of the speed reducer 83 via a chain transmission mechanism 88 having a tensioner (not shown). The support shaft 85 is rotatably supported by two girders 6. And the edge board 16 located in the left-right side of the trunk | drum floor board 8 is fixed to the girder 6 with the support member which is not shown in figure as a different body from the trunk | drum floor board 8. FIG.

  According to the swing type nursing bed apparatus of this embodiment, in addition to the same effects as the previous embodiment, the handle position adjusting mechanism for adjusting the position of the handle 81 for rising relative to the bed 1 and the flexible shaft of the transmission mechanism Since 82 can be omitted, the configuration can be further simplified and the care bed apparatus can be manufactured at a lower cost. Although not shown in the drawings, in each of the above embodiments, a cover is provided on a movable part such as the handle position adjusting mechanism or the chain transmission mechanism to prevent the clothes of the care recipient P and other foreign objects from being caught.

  Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described examples and can be appropriately changed within the scope of the claims. For example, the transmission mechanism extends in the longitudinal direction. A link mechanism or gear mechanism with a transmission shaft that rotates independently of the bed swinging around the existing horizontal axis, or a transmission shaft with a universal joint. It may be transmitted to the drive mechanism.

  The rising mechanism is provided with a rope, a wire, a chain, or the like for connecting the square pipe 7 and the beam 6 in place of or in addition to the swing limit position setting mechanism 43 to set the upper limit of the rising angle of the trunk floor plate 8. You may restrict | limit to about 80 degree | times.

  Further, a safety belt may be passed to the trunk floor plate 8 in the left-right direction so that the care recipient P does not fall off the bed 1 by mistake. Further, in order to facilitate the defecation processing and urination processing of the cared person on the bed 1, an opening may be provided at the base of the trunk side plates 9, 10, and the trunk side plates 9, 10 can be hinged. It may be a formula or may be removable.

  Thus, according to the swing type nursing bed apparatus of the present invention, the head support base, the trunk support base and the legs of the bed supported by the base so as to be swingable horizontally around the horizontal axis extending in the longitudinal direction. The support mechanism supports at least the head, torso, and legs of the cared person who lies on his / her back on the bed, and the swing mechanism moves around the horizontal axis that extends the bed in the longitudinal direction. The head support base, the torso support base and the leg support base are tilted to the left and right by, for example, about 30 degrees, so that the cared person turns over in the same way. This has the effect of moving the caregiver's pressed part to the opposite side, thereby effectively preventing the caregiver from rubbing the floor. Of course, the cared person may actually turn over by helping the bed tilt.

  In addition, according to the swing type nursing bed device of the present invention, when the bed is swung and the head support base, the trunk support base and the leg support base are inclined sideways, both sides of the head support base are The side wall of the head standing at the end supports the head of the cared person who lies on his back on the bed, and the side wall of the trunk standing on both sides of the torso support base lies on his back on the bed Since the side wall of the leg that supports the to-be-cared person's torso and the leg side walls that are erected on both sides of the leg support base supports the leg of the cared person who lies on his / her back on the bed, The caregiver can tilt the bed with confidence without fear of falling off the bed.

  According to the swing type nursing bed apparatus of the present invention, the cared person who lies on his / her back on the bed grabs the swing handle that swings with the bed and is placed within the reach of his / her hand. When rotated, the bed drive mechanism receives rotation from the swing handle that receives the human power of the cared person and rotates through the transmission mechanism and the speed reduction mechanism to swing the bed laterally, such as a hydraulic pump. Because it does not use a swing mechanism, the care bed device can be used in a place without a power source and can be manufactured at low cost, and even if the caregiver is not accompanied, the care recipient can tilt the bed by himself to prevent floor rubbing can do.
