For ease of description, only the parts relevant to this utility model are shown in the figure.

[0029] It should be noted that if the directional indications (such as up, down, front, back, etc.) involved in this utility model are only used to explain the relative positional relationship between the components in a certain specific posture, the directional indications will change accordingly if the specific posture changes; if the descriptions of "first", "second", etc. involved in this utility model are used for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0030] Depend on Figures 1 to 6 As can be seen, the excrement collection and sealing device of this utility model includes an annular support base 10, a lifting drive mechanism 11 for driving the annular support base 10 to rise / fall, a sealing and cutting structure disposed on the lower side of the annular support base 10, and a clamping structure 30 disposed between the annular support base 10 and the sealing and cutting structure. It also includes a garbage bag structure 40 detachably installed on the annular support base 10 for holding excrement; the garbage bag structure 40 includes an annular bottom cover 41 and an mounting bracket fixed to the inner side of the annular bottom cover 41. The cylindrical body 42 and the stacked cylindrical bag body 45 fitted onto the mounting cylindrical body 42 also include an annular upper cover 43 opposite to the annular bottom cover 41 and a connecting ring 44 fixed to the inner side of the annular upper cover 43, for fitting with the mounting cylindrical body 42 to confine the stacked cylindrical bag body 45 between the annular bottom cover 41, the mounting cylindrical body 42, and the annular upper cover 43. Furthermore, the inner side of the stacked cylindrical bag body 45 is clamped between the connecting ring 44 and the mounting cylindrical body 42 to prevent the stacked cylindrical bag body 45 from falling off. Specifically, the lifting drive mechanism 11 is an electric cylinder, and the output shaft of the lifting drive mechanism 11 is fixedly connected to the annular support seat 10. Of course, the lifting drive mechanism 11 can also be an electric push rod.

[0031] like Figure 5 As shown, the annular support base 10 includes an annular support plate 12 and a positioning ring 13 fixed to the inner side of the annular support plate 12. The output part of the lifting drive mechanism 11 is fixedly connected to the annular support plate 12. Typically, the lifting drive mechanism 11 is provided on opposite sides of the annular support base 10.

[0032] For ease of understanding, combined with Figure 5 The production and use of garbage bag structure 40 are explained as follows:

[0033] 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 45. The stacking direction is from the inside to the outside. The stacked tubular bag 45 is fitted onto the mounting cylinder 42, and the ring-shaped top cover 43 is fixed to the mounting cylinder 42 by fitting it between the connecting ring 44 and the mounting cylinder 42, thus forming the garbage bag structure 40.

[0034] In use, the mounting cylinder 42 of the garbage bag structure 40 is fitted onto the positioning ring 13 of the annular support base 10. The annular support plate 12 of the annular support base 10 can support the garbage bag structure 40. Then, the outermost layer of the stacked cylindrical bag body 45 is pulled along... Figure 5 The direction of the middle arrow passes through the garbage bag structure 40 and the ring support 10 from above, and stretches downward to the sealing and cutting structure. The sealing and cutting structure seals the cylindrical bag body at the lower side, so that the cylindrical bag body part between the sealing and cutting structure and the ring support 10 forms a garbage bag with a sealed lower side, which is used to hold excrement. After sealing, the sealing and cutting structure separates from the cylindrical bag body.

[0035] During discharge, the clamping structure 30 clamps the cylindrical bag between the sealing and cutting structure and the annular support 10. Then, the lifting drive mechanism 11 drives the annular support 10 and the garbage bag structure 40 placed on the annular support 10 to rise. Since the clamping structure 30 clamps the cylindrical bag between the sealing and cutting structure and the annular support 10, the cylindrical bag on the garbage bag structure 40 can be pulled out when the annular support 10 and the garbage bag structure 40 rise. Then, the clamping structure 30 releases the clamp between the sealing and cutting structure and the annular support 10. The cylindrical bag body; after excretion, the lifting drive mechanism 11 drives the annular support seat 10 and the garbage bag structure 40 to descend. The garbage bag part containing the excrement descends to the lower side of the sealing and cutting structure, and then the sealing and cutting structure seals it. After sealing, the sealing area is cut into upper and lower parts, so that the excrement is sealed inside a sealed garbage bag. The lower edge of the cylindrical bag body after cutting is also sealed for easy use next time. After the cylindrical bag body of the garbage bag structure 40 is used up, a new garbage bag structure 40 can be directly replaced.

[0036] This invention relates to an excrement collection and sealing device that can seal and store excrement, thus solving the problem of strong odor and unsanitary conditions in the surrounding environment after excretion by disabled persons.

[0037] In this utility model, the sealing and cutting structure includes a fixed heat-sealing seat 21 provided on the lower side of the annular support 10, a heat-sealing slide seat provided corresponding to the fixed heat-sealing seat 21, a sealing translation drive mechanism 23 for driving the heat-sealing slide seat to slide in a direction close to / away from the fixed heat-sealing seat 21, and a movable heat-sealing seat 22 provided on the side of the heat-sealing slide seat close to the fixed heat-sealing seat 21. An elastic buffer mechanism is provided between the movable heat-sealing seat 22 and the heat-sealing slide seat. It also includes a cutter fixed to the heat-sealing slide seat. The movable heat-sealing seat 22 is provided with a seam opening for the cutter to pass through. Typically, the sealing translation drive mechanism 23 is an electric cylinder or an electric push rod. During sealing, the sealing translation drive mechanism 23 drives the heat sealing slide and the movable heat sealing seat 22 to slide towards the fixed heat sealing seat 21 until the movable heat sealing seat 22 contacts the fixed heat sealing seat 21, thus heat sealing the cylindrical bag held between the two. After sealing, the sealing translation drive mechanism 23 drives the heat sealing slide to continue moving, which can push the cutter to continue moving towards the fixed heat sealing seat 21 until the cutter passes through the seam of the movable heat sealing seat 22 and cuts off the middle of the heat-sealed part.

[0038] Specifically, the fixed heat sealing base 21 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 22 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 correspondingly arranged with the upper fixed heat sealing plate, and the lower movable heat sealing plate is correspondingly arranged with 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 each electrically connected to the electrical control device.

[0039] The elastic buffer mechanism includes guide rods fixed at intervals to the movable heat-sealing seat 22. 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 22 and the heat-sealing slide. Typically, two guide rods are spaced apart.

[0040] 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.

[0041] In this invention, the clamping structure 30 includes a fixed clamping bar disposed on the lower side of the annular support 10, a movable clamping bar disposed corresponding to the fixed clamping bar, and a clamping drive mechanism for driving the movable clamping bar to slide in a direction close to / away from the fixed clamping bar. In use, the cylindrical bag body passes between the movable clamping bar and the fixed clamping bar. Typically, the clamping drive mechanism is an electric cylinder.

[0042] In this invention, the excrement collection and sealing device also includes a container (not shown in the figure) that is slidably installed on the lower side of the sealing and cutting structure for collecting garbage bags sealed with excrement. A window is provided on the left or right side of the bed frame 70 for the container to slide out, so that caregivers can easily remove the garbage bags.

[0043] Depend on Figure 6 As can be seen, the health care bed of this utility model includes a bed frame 70, a bed board 80 laid on the upper side of the bed frame 70, a drain hole 81 provided on the bed board 80, a support structure and an electrical control device provided at the drain hole 81; an excrement collection and sealing device is provided on the lower side of the drain hole 81, and the lifting drive mechanism 11, the clamping structure 30 and the sealing and cutting structure are electrically connected to the electrical control device.

[0044] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the support structure includes a left support structure 50a and a right support structure 50b provided on the left and right sides of the bed frame 70. The left support structure 50a and the right support structure 50b respectively include a support pad and a push-pull drive mechanism 56 for driving the support pad to flip downward to disengage from the drain hole 81 or flip upward to support the drain hole 81. The push-pull drive mechanism 56 is electrically connected to the electric control device. Typically, the push-pull drive mechanism 56 is an electric cylinder or an electric push rod.

[0045] For ease of understanding, when a disabled person lies flat on the rehabilitation bed, the side corresponding to the upper body of the disabled person is the head side of the bed frame 70, the side corresponding to the lower body of the disabled person is the foot side of the bed frame 70, the side corresponding to the right hand of the disabled person is the right side of the bed frame 70, and the side corresponding to the left hand of the disabled person is the left side of the bed frame 70.

[0046] When the disabled person lies flat on the rehabilitation bed, their buttocks are located at the excretion hole 81. The support pads of the left support structure 50a and the right support structure 50b can be flipped upwards to block the excretion hole 81 and support the disabled person's buttocks at the excretion hole 81. During excretion, the push-pull drive mechanism 56 of the left support structure 50a and the right support structure 50b drives the support pads to flip downwards and disengage from the excretion hole 81.

[0047] Specifically, the bed frame 70 includes a left and right frame spaced apart, multiple upper crossbeams connecting the upper sides of the left and right frames, multiple lower crossbeams connecting the lower sides of the left and right frames, and a base plate 60 laid on the lower crossbeams; typically, the main body of the lifting drive mechanism 11 is fixed to the base plate 60. Alternatively, the left and right frames can be formed from uprights, with the upper crossbeams fixed between the upper sides of the two uprights and the lower crossbeams fixed between the lower sides of the two uprights.

[0048] For safety purposes, a left side panel is provided on the left side of the bed frame 70, a right side panel is provided on the right side of the bed frame 70, a headboard is provided on the head side of the bed frame 70, and a footboard is provided on the foot side of the bed frame 70.

When the output shaft of the push-pull drive mechanism 56 retracts, it can pull the support pads downwards and flip them over. After the support pads flip, they can pull the support pads and the support slides 53 to slide along the guide rails 52, which can increase the distance between the support pads of the left support structure 50a and the right support structure 50b, thus preventing obstruction of the excrement collection sealing device.

[0050] For ease of installation, the left support structure 50a and the right support structure 50b also include a first bracket 51 and a second bracket 58 respectively fixed to the base plate 60.

The guide rail 52 is fixed to the first bracket 51, and the main body of the push-pull drive mechanism 56 is rotatably mounted on the second bracket 58. Specifically, the first bracket 51 and the second bracket 58 of the left support structure 50a and the first bracket 51 and the second bracket 58 of the right support structure 50b are respectively fixed to the base plate 60. Of course, the guide rail 52 can also be directly fixed to the bed frame 70, in which case the first bracket 51 and the second bracket 58 are no longer needed.

[0051] like Figure 2 and Figure 4As shown, to facilitate limiting the rotation angle of the support pad, a limiting plate 531 fixed to the support slide 53 is provided on the side of the support pad away from the drain hole 81. 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 part, and the support pad has a threaded hole. The threaded part 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. Of course, 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 70. Usually, the limiting rod 57 is a bolt, but a threaded rod can also be used. To facilitate the rotation of the threaded rod, an internal hexagon countersunk hole is provided at the end of the threaded rod.

[0052] Specifically, the guide rail 52 includes two parallel guide shafts. The support slide 53 has mounting through holes corresponding to each guide shaft, and a sleeve fitted onto the guide shaft is fixed in each mounting through hole.

[0053] 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 81, the soft pad 55 passes through the drain hole 81. 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.
