[0036] When in use, adjust the tail support 60 and the back support 70 to a horizontal position, and place the support pads of the left support structure 50a and the right support structure 50b on the excretion hole 21. The disabled person lies flat on the rehabilitation bed, with the upper body of the disabled person located at the position of the back support 70, the buttocks of the disabled person located at the excretion hole 21, and the lower legs of the disabled person located at the position of the tail support 60.

[0037] During defecation, the push-pull drive mechanism 56 of the left support structure 50a and the right support structure 50b drives the support pad to flip downwards and disengage from the defecation hole 21. At the same time, the back-lifting drive mechanism 71 drives the back-lifting bracket 70 to rotate upwards to lift the upper body of the disabled person. The flipping drive mechanism 65 drives the tail bracket 60 to flip downwards, and the lower legs of the disabled person follow the tail bracket 60 to descend, so that the disabled person is in a sitting position, which is convenient for the disabled person to defecate. After defecation, the cleaning and translation drive mechanism 46 drives the cleaning device 40 to move to the upper side of the collection device 30 to clean the buttocks of the disabled person. No manual cleaning by caregivers is required. The rehabilitation bed of this utility model solves the problems of the inconvenience of defecation for disabled people in the lying position and the inconvenience of cleaning after defecation.

[0038] In this utility model, the bed frame includes a left frame 11 and a right frame 12 arranged at intervals, multiple upper crossbeams 13 connected between the upper side of the left frame 11 and the upper side of the right frame 12, and multiple lower crossbeams connected between the lower side of the left frame 11 and the lower side of the right frame 12, with a base plate 19 laid on the multiple lower crossbeams.

[0039] Specifically, the tail support 60 is rotatably installed on the upper crossbeam 13 on the tail side of the corresponding bed frame, the back support 70 is rotatably installed between the upper side of the left frame 11 and the upper side of the right frame 12, and the toilet collection device 30 and the cleaning device 40 are respectively installed on the base plate 19.

A limiting rod 57 is provided on the support pad. When the support pad is flipped downwards, the limiting rod 57 can abut against the limiting plate 531. Furthermore, the limiting rod 57 has a threaded portion, and the support pad has a threaded hole. The threaded portion of the limiting rod 57 is installed in the threaded hole. When the limiting rod 57 is rotated, its length passing through the support pad can be adjusted, thereby adjusting the rotation angle of the support pad. As some other embodiments, the limiting rod 57 can also be set on the limiting plate 531, and the limiting rod 57 is set along the left and right direction of the bed frame. Specifically, the limiting rod 57 is a bolt. Of course, the limiting rod 57 can also be a threaded rod with an internal hexagon countersunk hole at the end of the threaded rod.

[0046] like Figure 2 and Figure 4 As shown, the guide slide rail 52 includes two guide shafts arranged in parallel. The support slide 53 is provided with mounting through holes corresponding to each guide shaft, and a sleeve fitted onto the guide shaft is fixed in each mounting through hole.

[0047] Specifically, the support pad includes a mounting plate 54 rotatably mounted on the support slide 53 and a soft pad 55 fixed to the mounting plate 54. When the support pad is flipped upwards to support the drain hole 21, the soft pad 55 passes through the drain hole 21. Typically, the soft pad 55 is made of soft materials such as silicone or rubber. Of course, it can also be made of leather-wrapped foam.

[0048] In some other embodiments, the support pads of the left support structure 50a and the right support structure 50b can also be directly rotatably mounted on the bed frame, the output shaft of the push-pull drive mechanism 56 is rotatably connected to the support pads, and the main body of the push-pull drive mechanism 56 is rotatably connected to the bed frame.

[0049] In this invention, the cleaning device 40 includes a cleaning bracket 41 fixed to the bed frame, a cleaning slide 42 slidably mounted on the cleaning bracket 41 along the head and foot directions of the bed frame, and a rotation drive mechanism 45 fixed to the cleaning slide 42.

It also includes a left cleaning brush roller 43a corresponding to the support pad of the left support structure 50a and rotatably mounted on the cleaning slide 42, and a support pad corresponding to the support pad of the right support structure 50b and rotatably mounted on the cleaning slide. The right cleaning brush roller 43b of the 42 and the buttock cleaning brush roller 43c located between the left cleaning brush roller 43a and the right cleaning brush roller 43b and rotatably mounted on the cleaning slide 42 are provided. The rotation axes of the left cleaning brush roller 43a, the right cleaning brush roller 43b and the buttock cleaning brush roller 43c are arranged in parallel and are connected to the rotation drive mechanism 45. The left cleaning brush roller 43a is used to clean the support pad of the left support structure 50a, the right cleaning brush roller 43b is used to clean the support pad of the right support structure 50b, and the buttock cleaning brush roller 43c is used to clean the buttocks of disabled persons.

[0050] Specifically, the drive mechanism 45 is a motor, with a drive pulley on the motor's output shaft. Driven pulleys are respectively located on the shafts of the left cleaning brush roller 43a, the right cleaning brush roller 43b, and the buttock cleaning brush roller 43c. A transmission belt is wound around the drive pulley of the motor, the driven pulley of the left cleaning brush roller 43a, the driven pulley of the right cleaning brush roller 43b, and the driven pulley of the buttock cleaning brush roller 43c. Of course, transmission can also be achieved by setting gears.

[0051] To facilitate the cleaning of the buttocks of disabled persons, a crankshaft 44 is fixed to one end of the buttock cleaning brush roller 43c. The crankshaft 44 is rotatably mounted on the cleaning slide 42. During cleaning, the buttock cleaning brush roller 43c rotates around the rotation axis of the crankshaft 44. It contacts the buttocks of the disabled person once for each rotation, allowing for intermittent cleaning, which improves cleaning comfort and avoids constant contact with the buttocks of the disabled person, thus preventing skin damage.

[0052] like Figure 2 , Figure 4 and Figure 5 As shown, the left cleaning brush roller 43a, right cleaning brush roller 43b, and buttock cleaning brush roller 43c each include a shaft 431.

Typically, each brush plate has a plurality of notches spaced along the axial direction of the sleeve 433.

[0053] The cleaning device 40 also includes a water supply mechanism and an air blowing mechanism, which are not shown in the figure. The water supply mechanism is connected to the axial holes on the shaft 431 of the left cleaning brush roller 43a, the right cleaning brush roller 43b, and the buttock cleaning brush roller 43c, respectively. The air blowing mechanism is connected to the axial holes on the shaft 431 of the left cleaning brush roller 43a, the right cleaning brush roller 43b, and the buttock cleaning brush roller 43c, respectively.

[0054] After the disabled person defecates, the cleaning translation drive mechanism 46 drives the cleaning device 40 to move to the upper side of the collection device 30. Water is supplied by the water supply mechanism to the axial holes on the shaft 431 of the left cleaning brush roller 43a, the right cleaning brush roller 43b, and the buttocks cleaning brush roller 43c. The water flows out through the elongated hole 432 and multiple cleaning holes 435 corresponding to the elongated hole 432, wetting the cleaning section 434. The rotation drive mechanism 45 drives the left cleaning brush roller 43a, right cleaning brush roller 43b, and buttocks cleaning brush roller 43c to rotate. When the left cleaning brush roller 43a rotates, it cleans the support pad of the left support structure 50a; when the right cleaning brush roller 43b rotates, it cleans the support pad of the right support structure 50b; and when the buttocks cleaning brush roller 43c rotates, it cleans the buttocks of the disabled person. The cleaning part 434 is cleaned by the outflowing water. After cleaning, the air blowing mechanism blows air into the axial holes on the shaft 431 of the left cleaning brush roller 43a, the right cleaning brush roller 43b, and the buttock cleaning brush roller 43c. Air can be blown through the elongated hole 432 and the multiple cleaning holes 435 corresponding to the elongated hole 432. The air blown out of the cleaning hole 435 of the left cleaning brush roller 43a can dry the support pad of the left cleaning brush roller 43a and the left cleaning brush roller 43a itself. The air blown out of the cleaning hole 435 of the right cleaning brush roller 43b can dry the support pad of the right cleaning brush roller 43b and the right cleaning brush roller 43b itself. The air blown out of the cleaning hole 435 of the buttock cleaning brush roller 43c can dry the buttock cleaning brush roller 43c itself and the buttocks of the disabled person.

[0055] To facilitate machining, the axial hole of the shaft 431 is a through hole. During machining, a tube can be directly selected, and then an elongated hole 432 can be machined on the tube. When in use, the end of the through hole away from the cleaning slide 42 can be sealed. Specifically, the ends of the shafts 431 of the left cleaning brush roller 43a and the right cleaning brush roller 43b near the cleaning slide 42 are rotatably mounted on the cleaning slide 42 via bearings, and a rotary pipe joint is installed at the end of the shaft 431 near the cleaning slide 42 for easy connection to the conveying pipeline; for the buttock cleaning brush roller 43c, the end of its shaft 431 near the cleaning slide 42 is fixedly connected to one end of the crankshaft 44, and a mounting shaft parallel to the shaft 431 is fixed at the end of the crankshaft 44 away from the shaft 431. The crankshaft 44 and the mounting shaft are respectively provided with axial holes, and the axial holes of the crankshaft 44 and the mounting shaft are through holes. The axial holes of the mounting shaft, the crankshaft 44, and the shaft 431 are connected. The mounting shaft is rotatably mounted on the cleaning slide 42 via bearings, and a rotary pipe joint is installed at the end of the mounting shaft away from the crankshaft 44. For ease of installation, a four-way valve and a three-way valve are provided at the corresponding cleaning slide 42. The four-way valve has three outlets and one inlet, and the three-way valve has one outlet and two inlets. A main connecting pipe is provided between the outlet of the three-way valve and the inlet of the four-way valve. A branch connecting pipe is provided between the three outlets of the four-way valve and the rotary pipe joints corresponding to the left cleaning brush roller 43a, the right cleaning brush roller 43b, and the mounting shaft of the buttock cleaning brush roller 43c. The water supply pipe of the water supply mechanism and the air blowing pipe of the air blowing mechanism are respectively connected to the two inlets of the three-way valve, and a solenoid valve is connected in series on the water supply pipe and the air blowing pipe.

[0056] Specifically, the water delivery mechanism includes a water tank and a water pump, with a water delivery pipe connected between the outlet of the water pump and the inlet of the three-way valve; the air blowing mechanism includes an air blowing fan, with an air blowing pipe connected between the air blowing port of the air blowing fan and the inlet of the three-way valve.

[0057] The cleaning slide 42 includes a base plate and a vertical plate fixed to the base plate. A guide rail, such as a slide rail slider assembly, is provided between the base plate and the cleaning bracket 41. The left cleaning brush roller 43a, the right cleaning brush roller 43b, and the buttock cleaning brush roller 43c are rotatably mounted on the vertical plate.

[0058] To facilitate the sliding of the cleaning slide 42 and the installation of the cleaning translation drive mechanism 46, a cleaning hinge seat is fixed to the bottom side of the bed frame. Specifically, the cleaning hinge seat is fixed to the base plate 19. The output shaft of the cleaning translation drive mechanism 46 is rotatably connected to the cleaning slide 42, and the main body of the cleaning translation drive mechanism 46 is rotatably mounted on the cleaning hinge seat. Alternatively, the cleaning translation drive mechanism 46 can be directly fixed to the cleaning bracket 41, with its output shaft fixedly connected to the cleaning slide 42.

[0059] In this invention, the waste collection device 30 includes an annular support 31 disposed below the discharge hole 21, a lifting drive mechanism 32 for driving the annular support 31 to rise / fall, and a sealing and cutting structure 33 disposed below the annular support 31. A clamping structure 34 is provided between the annular support 31 and the sealing and cutting structure 33. Specifically, the main body of the lifting drive mechanism 32 is fixed to the base plate 19, and the output shaft of the lifting drive mechanism 32 is fixedly connected to the annular support 31. Typically, the lifting drive mechanism 32 is an electric cylinder or an electric push rod.

[0060] like Figure 7 As shown, the annular support base 31 includes an annular support plate 311 and a positioning ring 312 fixed to the inner side of the annular support plate 311. The output part of the lifting drive mechanism 32 is fixedly connected to the annular support plate 311. Typically, lifting drive mechanisms 32 are provided on opposite sides of the annular support base 31.

[0061] Specifically, the garbage bag structure 90 includes an annular bottom cover 91, an installation cylinder 92 fixed to the inner side of the annular bottom cover 91, and a stacked cylindrical bag 95 fitted onto the installation cylinder 92. It also includes an annular top cover 93 opposite to the annular bottom cover 91 and a connecting ring 94 fixed to the inner side of the annular top cover 93 for fitting with the installation cylinder 92, thus confining the stacked cylindrical bag 95 between the annular bottom cover 91, the installation cylinder 92, and the annular top cover 93. Furthermore, the inner side of the stacked cylindrical bag 95 is clamped between the connecting ring 94 and the installation cylinder 92 to prevent the stacked cylindrical bag 95 from falling off.

[0062] For ease of understanding, combined with Figure 7 The following explains the production and use of garbage bag structure 90:

[0063] During production, long, strip-shaped tubular bags are prepared in advance, such as those with a length of 20m or 30m. The tubular bags are folded and stacked at a certain width, such as 7.5cm or 10cm, to form a ring-shaped stacked tubular bag 95. The stacking direction is from the inside out. The stacked tubular bag 95 is fitted onto the mounting tube 92, and the ring-shaped top cover 93 is fixed to the mounting tube 92 by fitting a connecting ring 94 between the top cover and the mounting tube 92. Consumers purchase the finished product.

[0064] In use, the mounting cylinder 92 of the garbage bag structure 90 is fitted onto the positioning ring 312 of the annular support 31. The annular support plate 311 of the annular support 31 supports the garbage bag structure 90. Then, the outermost layer of the stacked cylindrical bag 95 is pulled along... Figure 7The direction of the middle arrow passes through the garbage bag structure 90 and the annular support 31 from above, and stretches downward to the sealing and cutting structure 33. The sealing and cutting structure 33 seals the lower cylindrical bag body, so that the cylindrical bag body between the sealing and cutting structure 33 and the annular support 31 forms a garbage bag with a sealed lower side, which is used to hold excrement and wastewater after washing. After sealing, the sealing and cutting structure 33 separates from the cylindrical bag body.

[0065] When a disabled person urinates, the push-pull drive mechanism 56 of the left support structure 50a and the right support structure 50b drives the support pad to flip downwards and disengage from the discharge hole 21. The clamping structure 34 clamps the cylindrical bag between the sealing and cutting structure 33 and the annular support seat 31. Then, the lifting drive mechanism 32 drives the annular support seat 31 and the garbage bag structure 90 placed on the annular support seat 31 to rise. Because the clamping structure 34 clamps the cylindrical bag between the sealing and cutting structure 33 and the annular support seat 31, the cylindrical bag on the garbage bag structure 90 can be pulled out when the annular support seat 31 and the garbage bag structure 90 rise. Then, the clamping structure 34 releases the seal. The cylindrical bag between the cutting structure 33 and the annular support 31 allows disabled persons to excrete waste into the garbage bag sealed on the lower side of the annular support 31. After excretion, the lifting drive mechanism 32 drives the annular support 31 and the garbage bag structure 90 to descend. The garbage bag containing the excrement and the wastewater after washing descends to the lower side of the sealing and cutting structure 33, where it is sealed. The sealed area is then cut into upper and lower parts, so that the excrement and the wastewater after washing are sealed inside a sealed garbage bag. The lower edge of the cut cylindrical bag is also sealed for future use.

[0066] Specifically, the sealing and cutting structure 33 includes a fixed heat-sealing seat 331 located on the lower side of the corresponding annular support 31, a heat-sealing slide mounted on the bed frame in a direction close to / away from the fixed heat-sealing seat 331, a sealing translation drive mechanism 333 for driving the heat-sealing slide to slide, and a movable heat-sealing seat 332 located on the side of the heat-sealing slide close to the fixed heat-sealing seat 331. An elastic buffer mechanism is provided between the movable heat-sealing seat 332 and the heat-sealing slide. It also includes a cutter fixed to the heat-sealing slide. The movable heat-sealing seat 332 has a seam opening for the cutter to pass through. Typically, the sealing translation drive mechanism 333 is an electric cylinder or an electric push rod. During sealing, the sealing translation drive mechanism 333 drives the heat sealing slide and the movable heat sealing seat 332 to slide towards the fixed heat sealing seat 331 until the movable heat sealing seat 332 contacts the fixed heat sealing seat 331, thus heat sealing the cylindrical bag held between the two. After sealing, the sealing translation drive mechanism 333 drives the heat sealing slide to continue moving, which can push the cutter to continue moving towards the fixed heat sealing seat 331 until the cutter passes through the seam of the movable heat sealing seat 332 and cuts off the middle of the heat-sealed part.

[0067] The fixed heat sealing base 331 includes a fixed base, with an upper fixed heat sealing plate and a lower fixed heat sealing plate spaced apart along the vertical direction. The movable heat sealing base 332 includes a mounting plate, with an upper movable heat sealing plate and a lower movable heat sealing plate spaced apart along the vertical direction. The upper movable heat sealing plate is corresponding to the upper fixed heat sealing plate, and the lower movable heat sealing plate is corresponding to the lower fixed heat sealing plate. The seam is located at the mounting plate between the upper movable heat sealing plate and the lower movable heat sealing plate. The upper fixed heat sealing plate, the lower fixed heat sealing plate, the upper movable heat sealing plate, and the lower movable heat sealing plate are electrically connected to the electrical control device.

[0068] The elastic buffer mechanism includes guide rods fixed at intervals to the movable heat-sealing seat 332. Each guide rod has a guide hole at a corresponding location on the heat-sealing slide. The guide rod passes through the corresponding guide hole, and a limiting nut is provided at the end of the guide rod passing through the guide hole. It also includes a spring sleeved on the guide rod between the movable heat-sealing seat 332 and the heat-sealing slide. Typically, two guide rods are spaced apart.

[0069] In some other embodiments, the upper fixed heat sealing plate and the lower fixed heat sealing plate are connected as an integral structure, and the upper movable heat sealing plate and the lower movable heat sealing plate are connected as an integral structure.

[0070] The clamping structure 34 includes a fixed clamping block disposed on the lower side of the annular support 31, a movable clamping block disposed corresponding to the fixed clamping block, and a clamping drive mechanism for driving the movable clamping block to slide in a direction close to / away from the fixed clamping block. In use, the cylindrical bag body passes between the movable clamping block and the fixed clamping block. Typically, the clamping drive mechanism is an electric cylinder.

[0071] Furthermore, the waste collection device 30 also includes a container that is slidably installed on the lower side of the sealing and cutting structure 33 along the left and right direction of the bed frame. This container is used to collect garbage bags containing excrement and wastewater. A window is provided on the left or right side of the bed frame for the container to slide out, so that caregivers can easily remove the garbage bags.

The output shaft of the flipping drive mechanism 65 is rotatably connected to the lower connecting frame 63, and the main body of the flipping drive mechanism 65 is rotatably connected to the bed frame.

[0073] During excretion, the flipping drive mechanism 65 drives the connecting frame to flip downwards. Because a parallelogram linkage mechanism is formed between the rotating connections of the upper connecting frame 62 and the support frame 61, the upper connecting frame 62 and the bed frame, the lower connecting frame 63 and the support frame 61, and the lower connecting frame 63 and the bed frame, the support frame 61 remains horizontal throughout the downward flipping process. When flipped to the underside of the bed frame, it can support the person's feet. Figure 9 As shown; after excretion, the flipping drive mechanism 65 drives the connecting frame to flip upwards until the support frame 61 moves to a position basically flush with the upper side of the bed frame, as shown.

The headboard bed section 22 is provided with a groove 224 corresponding to each bed board roller 72, so that the headboard bed section 22 can be lifted when the backrest support 70 is flipped upward.

[0077] Specifically, the groove of the slide 224 faces the left or right side of the bed frame; when the backrest support 70 is in a horizontal state, the bed board rollers 72 are located outside the port of the slide 224; when the backrest support 70 is flipped upward, the bed board rollers 72 rotate synchronously with the backrest support 70 and slide into the interior of the slide 224 from the port of the slide 224.

[0078] In some other embodiments, the groove of the slide 224 may also be positioned facing the bottom side of the bed frame, and the bed rollers 72 are always engaged inside the slide 224.

[0079] In this utility model, such as Figure 10 As shown, the headboard section 22 includes a mounting plate section 221 rotatably connected to the middle bed section 23, a left bed section 222 and a right bed section 223 disposed on the side of the mounting plate section 221 away from the middle bed section 23.

[0081] To facilitate turning over, a turning device 80 is provided between the bed frame and the left bed board 222 and the right bed board 223. When it is necessary to turn over to the left, the turning device 80 drives the right bed board 223 to flip to the left. When it is necessary to turn over to the right, the turning device 80 drives the left bed board 222 to flip to the right.
