Description

  The present invention relates to a care bed and a head-gudge up attachment that are effective for preventing an error when a care recipient eats and drinks while depositing in a bed.

  Patent documents 1 and 2 disclose an invention related to bed up. Here, "gudge up" is an industry term and means the function of raising the back of the bed and raising feet.

  Patent Document 1 discloses a motorized care bed. The care bed is composed of several sections that support the mattress. Specifically, (i) head bottom corresponding to the human head, (ii) back bottom corresponding to the back, (iii) hip corresponding to the human body part lying on the mattress It consists of five sections: the center bottom, (iv) the thigh bottom corresponding to the thigh, and (v) the leg bottom corresponding to the lower leg. The five sections are bendably connected between the sections adjacent to each other.

  The electric caring bed is based on a lying posture in which the above five sections are in a horizontal position to form a flat surface, and a back-raising posture and a foot-raising posture are formed by raising the back bottom and the thigh bottom. Further, by raising the head bottom against the back bottom raised, the care recipient can take a reclining posture in which the desired head and neck angle is maintained with the upper body in the bed.

  Patent document 2 similarly discloses a bed in which a bottom is composed of several sections. Specifically, Patent Document 2 proposes raising the back height. The back raised reach disclosed in Patent Document 2 has a back bottom frame, and the back bottom is fixed to the back bottom frame. Also, the back bottom frame has a non-displaceable fixed shaft, and the head bottom is pivotally supported on this shaft. And, the back lift gage up has a plurality of links linked to each other, and by the action of the plurality of links, it is possible to change the posture to the back up position and adjust the rising angle of the head bottom with respect to the back bottom it can.

  Of course, in dietary assistance, the assistant needs to pay close attention to the aspiration of the care recipient. In order to prevent aspiration, it is effective to optimize the attitude of the care recipient in the bed. That is, it is effective to optimize the anteflexion and the angle of the head and neck of the care recipient when receiving the dietary assistance in the state where the care recipient has the upper body in the reclining posture.

  Since the position of the spindle of the head bottom is fixed, the assistant adjusts the forward bending angle of the head and neck of the care recipient according to the position of the pillow. The needs of the carers vary in size and condition. Because of this, the assistant changes the position of the pillow below the head of the care recipient and listens to the situation of the care recipient afterward. If the care recipient can not lift his head freely with his or her own power, it is practically difficult to fine-tune the pillow placement position.

  As described above, there is a risk that an aspiration may be induced if the head and neck region of the care recipient is not properly flexed. Aspiration causes the development of aspiration pneumonia.

  An object of the present invention is to provide a care bed and a head, a gage-up attachment, which can optimize an anteflexion angle of the head and neck of the care recipient only by the operation of a care person according to the physical size of the care recipient. To provide.

  Hereinafter, preferred embodiments of the present invention will be described based on the attached drawings.

  FIG. 1 shows a care bed 100 of the embodiment. The care bed 100 has a bottom 4 located below the mattress 2 and supporting the mattress 2, which bottom 4 is composed of several sections as before. The bottom 4 is a head bottom 4H corresponding to the human head, a back bottom 4B corresponding to the back, a central bottom 4C corresponding to the buttocks, a thigh corresponding to a human body part lying on the mattress 2 It consists of 5 sections of the thigh bottom 4F corresponding to and the lower leg bottom 4L corresponding to the lower leg.

  Among the above-described sections, the features of the present invention are included in the head bottom 4H, so the features of the present invention will be specifically described below. First, the outline of the care bed 100 will be described. First, the bed 100 can adjust the rising angle of the head bottom 4H with respect to the back bottom 4B. That is, the head bottom 4H can be rocked and raised about the pivot axis Pa, and the rise angle can be adjusted. The nursing bed 100 secondly displaces the pivot axis Pa of the head bottom 4H. The direction of displacement of the pivot axis Pa is the longitudinal direction of the bed 100. That is, the pivot axis Pa can be displaced in the direction of the height of the care recipient Tdc lying on the bed 100.

  The rising of the head bottom 4H and the displacement of the pivot axis Pa may be operated by an actuator, typically an electric motor, but the bed 100 preferably has manual first and second handles 10, 12 It is good to have The first handle 10 is used to adjust the rising angle of the head bottom 4H. The first handle 10 is disposed on one end face of the bed 100 on the head side. The helper Hp can adjust the rising angle of the head bottom 4H while operating the first handle 10. In this adjustment operation, the workability of the assistant Hp can be improved by adopting the lever-shaped first handle 10.

  The second handle 12 is used to adjust the displacement position of the pivot axis Pa of the head bottom 4H. The second handle 12 is disposed on both sides of the bed 100 adjacent to the head bottom 4H. The helper Hp can displace the pivot axis Pa of the head bottom 4H while operating one of the second handles 12.

  The essential parts of the care bed 100 of the embodiment will be described in detail with reference to the drawings after FIG. 2. FIG. 2 shows a back raising reach 20 including a back bottom 4B and a head bottom 4H. FIG. 2 is a perspective view of the back raising reach 20. As shown in FIG. FIG. 3 is an exploded perspective view of the back raising reach 20. FIG. 4 is a side view of the back raising reach 20.

  With reference to FIGS. 2 and 3, back raising gap-up portion 20 has back raising frame 22 extending along the outline of a rectangular shape in a front view, and back bottom 4B is integrally incorporated in back raising frame 22. ing. As in the prior art, the back-raising gauge-up unit 20 can rise relative to the central bottom 4C, and its drive source is typically an electric motor.

  The backrest frame 22 has first and second two cross members 24 and 26. Referring to FIG. 3, the back raising frame 22 has a pair of guide rails 28 extending in the height direction of the lying care recipient Tdc, and the pair of guide rails 28 extend in parallel to one another. Each guide rail 28 extends between the top cross member 22 a (FIG. 3) of the back raising frame 22 and the second cross member 26. The head bottom 4H is assembled to the back raising frame 22 through the pair of guide rails 28.

  In the following description, the height direction of the lying care recipient Tdc is referred to as the “longitudinal direction”, and in this longitudinal direction, the care recipient's head direction is referred to as the “head direction”, and the care recipient's legs The direction of is called "leg direction".

  Referring to FIG. 3, the head bottom 4H is attached to the slide frame 30, and the slide frame 30 constitutes a part of the head / gage up mechanism 32. The slide frame 30 has a head frame main body 34 and a pair of sliders 36, and each slider 36 is engaged with each of the guide rails 28 described above. The pair of sliders 36 can be moved in the longitudinal direction by being guided by the pair of guide rails 28 described above.

  The head frame body 34 has its leg direction end 34 a connected to the slider 36 via a pivot axis Pa. The pivot axis Pa extends in the width direction of the bed 100. The head frame body 34 can swing by this pivot axis Pa. The head frame main body 34 constitutes a part of the head bottom 4H. Therefore, the head bottom 4H can rise relative to the back raising frame 22 about the pivot axis Pa. In other words, the head bottom 4H can be in a fallen posture located in the same plane as the back raising frame 22 and a posture rising up around the leg direction end 34a (pivot axis Pa) of the head bottom 4H. The angle of this rising posture can be adjusted arbitrarily. This point will be described later.

  The back-raising gauge-up portion 20 has a cross member 40 connected to the head direction end of the pair of sliders 36 (FIG. 3), and the cross member 40 extends from one end to the other end in the width direction of the bed 100 ing. The second handle 12 described above is installed at one end and the other end of the cross member 40 (FIG. 3). The proximal end of the gas spring 44 is attached to the longitudinal middle portion of the cross member 40 via an extension member 42 (FIG. 4). Both ends of the cross member 40 are fixed to the back raising frame 22 (FIG. 5).

  Referring to FIG. 3, the head frame body 34 has a cross member 46 at a position adjacent to its leg direction end 34a, and a swing link 48 is attached to a longitudinal middle portion of the cross member 46. . The free end of the gas spring 44 described above is connected to the swing link 48. As is well known, the gas spring 44 starts the extension operation by the internal gas pressure when the lock is released. In addition, it has a function of shortening when pressed with a force larger than this gas pressure. With the above configuration, the gas spring 44 constitutes a part of the head / gage up mechanism 32 and serves as a drive source for assisting the operation of raising the head frame main body 34, ie, the head bottom 4H.

  5 to 7 are diagrams for explaining the details of the back-raising reach 20, and FIG. 5 is a perspective view of the back-up reach 20 seen obliquely from below. FIG. 6 is a perspective view in which a part of the head bottom 4H of the back-raising gap-up unit 20 is removed, and FIG. 7 is a perspective view of the head bottom 4H as viewed from the rear side.

  Referring to FIG. 7, the first handle 10 described above is constituted by a lever handle pivoting about one end, and the first handle 10 is a top cross located at an end in the head direction of the head frame main body 34. It is attached to the member 34b. The first handle 10 is connected to the gas spring 44 via a wire 50 and is biased in the release direction by a spring (not shown).

  When the assistant performs an operation of gripping the first handle 10, the operation is transmitted to the lock mechanism part of the gas spring 44 by the wire 50, and the lock of the gas spring 44 is released. Thereby, the biasing force of the gas spring 44 acts on the head bottom 4H, and the rising operation of the head bottom 4H can be assisted. In addition, the head bottom 4H can be laid down by shortening the gas spring 44 against the biasing force of the gas spring 44 by exerting a force in the direction of pushing down the head bottom 4H by the assistant. Then, when the first handle 10 is released, the gas spring 44 is immediately locked. Thus, the head bottom 4H can be fixed in position at the rising angle when the first handle 10 is released.

  Referring to FIG. 1, the bed 100 has a second handle 12, and as described above, the position of the pivot axis Pa can be adjusted by operating the second handle 12. FIG. 8 is a view for explaining the second handle 12 and the lock mechanism 52 linked thereto.

  As described above, the second handle 12 is disposed at both ends of the cross member 40 fixed to both sides of the back raising frame 22 (FIG. 5). A lock member 54 is disposed at an intermediate portion between one end and the other end of the cross member 40. The lock member 54 is disposed to face one of the guide rails 28 of the pair of guide rails 28. The lock member 54 is pivotable about a shaft 54a, and can take a lock position where the lock member 54 engages with the side surface of the guide rail 28 and a release position away from the side surface of the guide rail 28. The locking member 54 is optionally fixed with a rubber 56 on the surface engaging with the guide rail 28. When the locking member 54 is in the locked position, the locking member 54 is locked to the guide rail 28 via the rubber 56.

  Referring to FIG. 8, the locking member 54 has a spring 58 biased in the locking direction. The second handle 12 has a handle shape. The second handle 12 is linked to the locking member 54 via a wire 60. As described above, the second handle 12 is disposed in a pair on the left and right. The handle-shaped second handle 12 is attached at one end thereof to the back raising frame 22 via the shaft 12a. The lock member 54 can be operated by operating one of the pair of left and right second handles 12.

  FIG. 8 illustrates the second handle 12 in an upright state. When the second handle 12 takes the upright position shown in FIG. 8, the lock member 54 can form a locked state engaged with the guide rail 28. Thereby, the position of the pivot axis Pa of the head bottom 4H can be fixed.

  FIG. 9 is a view for explaining the operation when the second handle 12 on the right side is tilted among the pair of second handles 12. When the second handle 12 on the left side is turned down instead of the right side, substantially the same action is exerted. When one of the pair of second handles 12 is turned down, it is necessary to operate the second handle 12 against the biasing force of the spring 58. In other words, the second handle 12 is returned to the upright position by the spring 58 by releasing the force applied to knock down the second handle 12.

  When the second handle 12 is turned over, the lock member 54 swings away from the guide rail 28. That is, when the second handle 12 is turned down, the lock by the lock member 54 is released. By releasing the lock, the position of the pivot axis Pa can be adjusted. That is, the longitudinal position of the head bottom 4H can be adjusted. When the head bottom 4H can be adjusted to a desired position, the position of the head bottom 4H can be fixed by releasing the hand from the second handle 12.

  Adjustment of the care bed 100 in accordance with the physical size of the care recipient Tdc will be described with reference to FIGS. 10 and 11. FIG. 10 is a diagram associated with a relatively tall carer Tdc (eg, height 165 cm), and FIG. 11 is a diagram associated with a relatively short carer Tdc (eg, height 145 cm).

  The back elevation angle of the care bed 100, that is, reclining, is adjusted using an electric motor as in the prior art. Even in the same care recipient Tdc, the inflection point of the head and neck changes slightly depending on the position of the bed 100 lying down. The head and neck inflection point is unique for each carer Tdc whose height is different. As can be clearly understood by comparing FIG. 10 with FIG. 11, the position of the pivot axis Pa is different. In general, a pillow PL is placed under the head of the care recipient Tdc. In this state, the second handle 12 is operated to release the lock, and the longitudinal position of the pivot axis Pa is adjusted. Since the second handle 12 has a handle shape, by moving the second handle 12 in the longitudinal direction with the hand holding the second handle 12, it can be adapted to the care recipient Tdc who is in bed. The pivot axis Pa can be positioned at the desired position.

  Adjustment of the bending angle of the head neck of the care recipient Tdc can be performed by operating the first handle 10 to adjust the rising angle of the head bottom 4H. Since the gas spring 44 assists the rising operation of the head bottom 4H, the burden on the assistant Hp can be reduced. In addition, when the head bottom 4H stands too much, the gas spring 44 is shortened by applying a force to the head bottom 4H to push down the head bottom 4H, and the rising angle of the head bottom 4H becomes smaller. When the appropriate rise angle is reached, the head bottom 4H can be released, and the release angle of the head bottom 4H can be fixed simply by releasing the hand from the first handle 10.

  Therefore, the caretaker Tdc in a state in which the body is entrusted to the bed 100 is finely adjusted while the rise angle of the head bottom 4H and the position of the pivot axis Pa are adjusted while watching the actual eating. It is possible to optimize the flexion angle of the head and neck.

  12 to 14 show the head reach up attachment of the embodiment. The illustrated head reach up attachment 200 has substantially the same structure as the back lift reach up unit 20 described above.

  The head reach up attachment 200 has a base 202 in place of the back raising frame 22 described above. The base 202 is substantially the same as the above-described back raising frame 22, but its longitudinal length is small and does not have substantially the function of the back bottom 4B. That is, the lower end cross member of the base 202 is configured by the second cross member 26 (FIG. 3) of the back raising frame 22 described above.

  210 shown in FIG. 12 shows the bottom of a conventional care bed. 210B is a conventional back bottom, 210C is a conventional center bottom, 210F is a conventional thigh bottom, and 210L is a conventional lower leg bottom.

  The head-gage-up attachment 200 of the embodiment is used by attaching the base 202 to the back bottom 210B. By fixing the base 202 to the back bottom 210B of the conventional care bed using the fixture 220, the head-gage up attachment 200 is attached to the conventional care bed. FIG. 13 shows the head-gage-up attachment 200 secured to the back bottom 210B of a conventional care bed. Thus, the head bottom 4H can be raised about the pivot axis Pa, and the pivot axis Pa can be displaced in the longitudinal direction, as in the case of the care bed 100 of the embodiment described above (FIG. 14) .
