Description

Technical Field

[0001] This invention relates to the field of nursing bed technology, specifically providing a fully automatic bedridden waste disposal system. Background Technology

[0002] With the continued acceleration of global population aging, the number of disabled and semi-disabled elderly people in my country is showing a year-on-year increasing trend. Due to the decline or loss of physical functions, these people have a serious lack of self-care ability and cannot live without the comprehensive care of caregivers. Among the many nursing tasks, excretory care is a high-frequency and tedious core task. Because disabled elderly people are bedridden for a long time, they cannot complete the excretory actions independently, and the timing and frequency of excretion are highly uncertain. They must rely on external assistive tools to meet their excretory needs.

[0003] Most existing bedridden excretion assistance devices can only achieve basic excretion reception functions and cannot automatically separate the patient's buttocks. This results in the anus and perianal area not being fully exposed during excretion, which hinders the smooth discharge of excrement and causes excrement residue. Residual excrement significantly increases the difficulty and workload of subsequent cleaning, not only increasing the workload of caregivers but also potentially causing perianal skin inflammation, infection, and other health problems due to incomplete cleaning. This seriously affects the quality of life of disabled elderly people and fails to meet the refined and humane needs of excretion care in actual nursing scenarios. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides a fully automatic bedridden excretion system. Its purpose is to solve the problem that existing technologies cannot automatically separate the patient's buttocks, resulting in the anus and perianal area not being fully exposed during excretion, thus hindering the smooth discharge of excrement.

[0005] To achieve the above objectives, the present invention provides a fully automatic bedpan excretion system, comprising a bed frame and a toilet installed on the ground. The bed frame has an internal excretion trough and two receiving slots. Two symmetrical baffles are slidably connected inside the excretion trough, with the opposite sides of the baffles slidably inserted into the two receiving slots. A rectangular frame is fixedly connected to the bottom surface of the bed frame, positioned directly above the toilet. Two first movable plates are slidably connected inside the rectangular frame, with the upper surfaces of the first movable plates fixedly connected to the bottom surfaces of the baffles. Two third rectangular columns are slidably connected vertically inside the rectangular frame. A first spring is fixedly connected to the outer surface of each third rectangular column, and a first wedge plate is fixedly connected to the other end of each first spring. A flexible plate is fixedly mounted on the upper surface of the first wedge plate. The baffles have internal clearance grooves for the movement of the flexible plate and the first wedge plate. A drive mechanism is located below the bed frame.

[0006] As a preferred embodiment, the toilet is a smart toilet with washing and drying functions.

[0007] As a preferred embodiment, the drive mechanism includes two support plates fixedly connected to the bottom surface of the bed. A dual-axis motor is fixedly installed on the outer surface of the rectangular frame. Both output ends of the dual-axis motor are fixedly connected to threaded rods. The other ends of the two threaded rods are rotatably installed inside the two support plates, and threaded plates are threadedly connected to the outer surfaces of the two threaded rods.

[0008] As a preferred embodiment, a second connecting rod is fixedly connected to the side of each of the two threaded plates that are close to each other, and the other end of the second connecting rod is slidably inserted into the inside of the rectangular frame and fixedly connected to the first movable plate.

[0009] As a preferred embodiment, the driving mechanism further includes a second movable plate slidably disposed inside the rectangular frame. A second wedge plate, adapted to the first wedge plate, is fixedly connected to the upper surface of the second movable plate, and the inclined surface of the second wedge plate contacts the inclined surface of the first wedge plate.

[0010] As a preferred embodiment, the second movable plate has an internal mounting hole, and a second spring is fixedly connected inside the mounting hole. The other end of the second spring is fixedly connected to a slider, which is horizontally slidably connected inside the baffle.

[0011] As a preferred embodiment, a second rectangular column is fixedly connected to the side of the second movable plate close to the first movable plate, a third wedge plate is fixedly connected to the bottom surface of the second rectangular column, and a fourth wedge plate adapted to the third wedge plate is fixedly connected to the side of the first movable plate away from the second movable plate, and the inclined surface of the fourth wedge plate is in contact with the inclined surface of the third wedge plate.

[0012] As a preferred embodiment, the interior of the rectangular frame is fixedly connected with a vertical plate for blocking the second rectangular column.

[0013] As a preferred embodiment, the bottom surface of the slider is fixedly connected to a guide post, and the other end of the guide post is slidably inserted into the interior of the second rectangular post.

[0014] As a preferred embodiment, the other end of the first rectangular column slides through the through slot and extends to the outside of the first movable plate, and the other end of the first connecting rod slides into the inside of the third rectangular column.

[0015] The purpose of this invention is to provide a fully automatic bedridden excretion treatment system, which has the following beneficial effects: ① By setting up a driving mechanism, the present invention can automatically open the baffle to expose the toilet before excretion, and at the same time open the patient's buttocks to fully expose the anus and perianal area, thereby fundamentally eliminating the obstruction of excrement discharge, ensuring a smooth excretion process, avoiding the problem of excrement residue, and creating good conditions for subsequent cleaning work.

[0016] ② By using a flexible plate that contacts the patient's buttocks, this invention can effectively avoid pressure or friction damage to the patient's skin, ensuring the patient's safety. At the same time, the toilet's washing and drying functions can clean and dry the patient's perianal area in a timely manner after defecation, reducing skin irritation, improving the patient's comfort and experience, and maintaining the patient's cleanliness and health.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] like Figures 1 to 7As shown, this invention provides a fully automatic bedridden excretion system, including a bed 1 and a commode 2 installed on the ground. The commode 2 can accurately receive excrement without requiring the patient to move their body, adapting to bedridden use scenarios. The bed 1 has an excretion trough 3 and two receiving slots inside. The excretion trough 3 provides a channel for excrement to fall. Two symmetrical baffles 5 are slidably connected inside the excretion trough 3, and the sides of the two baffles 5 that are far apart from each other are slidably inserted into the two receiving slots. The baffles 5 are closed when not in the excretion state, which can maintain the integrity of the surface of the bed 1 and avoid discomfort for the patient when lying down. When excretion is required, they slide open into the receiving slots, exposing the excretion trough 3.

[0021] A rectangular frame 4 is fixedly connected to the bottom surface of the bed frame 1, and the rectangular frame 4 is located directly above the toilet bowl 2. The rectangular frame 4 provides installation and movement space for various transmission components, and can guide excrement to fall accurately into the toilet bowl 2 below, preventing excrement from scattering. Two first movable plates 6 are slidably connected inside the rectangular frame 4, and the upper surface of the first movable plates 6 is fixedly connected to the bottom surface of the baffle 5. The movement of the first movable plates 6 can directly drive the baffle 5 to slide synchronously, realizing the opening and closing control of the baffle 5. Two third rectangular posts 26 are slidably connected vertically inside the rectangular frame 4, and the outer surface of the third rectangular posts 26 is fixedly connected to the third rectangular posts 26. A spring 7 is provided, and a first wedge plate 8 is fixedly connected to the other end of the first spring 7. The first spring 7 has an elastic reset function, which can drive the first wedge plate 8 back to the initial position when reset. A flexible plate 9 is fixedly installed on the upper surface of the first wedge plate 8. The flexible plate 9 is made of a soft and skin-friendly material to avoid skin damage when in contact with the patient's buttocks. At the same time, it can conform to the contour of the buttocks to ensure the separation effect. The baffle 5 has a clearance groove inside for the flexible plate 9 and the first wedge plate 8 to move. The clearance groove provides sufficient space for the flexible plate 9 and the first wedge plate 8 to move up and down and left and right, so as to avoid interference with the baffle 5.

[0022] Toilet 2 is a smart toilet with washing and drying functions. This design allows the patient to automatically wash the perianal area after defecation without the need for manual cleaning by caregivers. The toilet 2 keeps the skin dry by washing the perianal area, which not only improves the patient's comfort but also reduces the workload of caregivers and effectively avoids skin problems caused by incomplete cleaning.

[0023] A drive mechanism is provided below the bed body 1. The drive mechanism includes two support plates 19 fixedly connected to the bottom surface of the bed body 1. A dual-axis motor 20 is fixedly installed on the outer surface of the rectangular frame 4. Both output ends of the dual-axis motor 20 are fixedly connected to threaded rods 21. The other ends of the two threaded rods 21 are respectively rotatably installed inside the two support plates 19. The outer surfaces of the two threaded rods 21 are threadedly connected to threaded plates 22. The threaded plates 22 and the threaded rods 21 are tightly threaded together, which can move stably along the axis direction when the threaded rods 21 rotate, thereby driving the subsequent components to move.

[0024] The two threaded plates 22 are fixedly connected to each other on their adjacent sides by a second connecting rod 23, and the other end of the second connecting rod 23 is slidably inserted into the inside of the rectangular frame 4 and fixedly connected to the first moving plate 6. The second connecting rod 23 can accurately transmit the linear movement power of the threaded plate 22 to the first moving plate 6, so that the first moving plate 6 moves synchronously with the threaded plate 22.

[0025] The driving mechanism also includes a second movable plate 11 slidably disposed inside the rectangular frame 4. The second movable plate 11 can move horizontally and vertically within the rectangular frame 4. A second wedge plate 14 adapted to the first wedge plate 8 is fixedly connected to the upper surface of the second movable plate 11, and the inclined surface of the second wedge plate 14 contacts the inclined surface of the first wedge plate 8. The inclined surfaces of the two wedge plates fit precisely, which can convert the vertical power of the second movable plate 11 into the horizontal power of the first wedge plate 8, thereby realizing the horizontal separation action of the flexible plate 9.

[0026] The second movable plate 11 has an installation hole inside, and a second spring 12 is fixedly connected inside the installation hole. The other end of the second spring 12 is fixedly connected to a slider 25. The slider 25 is horizontally slidably connected inside the baffle 5. The sliding cooperation of the slider 25 inside the baffle 5 ensures that the second movable plate 11 can move horizontally synchronously with the baffle 5, while not affecting its vertical movement.

[0027] A second rectangular column 15 is fixedly connected to the side of the second movable plate 11 closest to the first movable plate 6. A third wedge plate 16 is fixedly connected to the bottom surface of the second rectangular column 15. A fourth wedge plate 17, which is adapted to the third wedge plate 16, is fixedly connected to the side of the first movable plate 6 away from the second movable plate 11. The inclined surface of the fourth wedge plate 17 is in contact with the inclined surface of the third wedge plate 16. The inclined surfaces of the third wedge plate 16 and the fourth wedge plate 17 cooperate to convert the horizontal force of the first movable plate 6 into the vertical force of the second rectangular column 15 and the second movable plate 11, realizing the conversion of force direction and providing power for the upward movement of the flexible plate 9.

[0028] The rectangular frame 4 is fixedly connected to a vertical plate 18 for blocking the second rectangular column 15. The vertical plate 18 can block the second rectangular column 15 when it moves to the preset position, so that the second rectangular column 15 and the second moving plate 11 stop moving horizontally, creating conditions for the subsequent fourth wedge plate 17 to squeeze the third wedge plate 16 to achieve vertical movement, and ensuring the orderly connection of the actions.

[0029] The bottom surface of the slider 25 is fixedly connected to the guide post 24. The other end of the guide post 24 is slidably inserted into the guide hole inside the second rectangular post 15. The guide post 24 can play a guiding and limiting role between the slider 25 and the second rectangular post 15, ensuring that the second moving plate 11 moves in a fixed direction when moving vertically, avoiding deviation or tilting, and ensuring the transmission accuracy between the wedge plates.

[0030] The outer surface of the first wedge plate 8 is fixedly connected to the first rectangular post 10 and the first connecting rod 13. The interior of the first movable plate 6 has a through groove adapted to the first rectangular post 10. The other end of the first rectangular post 10 slides through the through groove and extends to the outside of the first movable plate 6. The cooperation between the first rectangular post 10 and the through groove can guide and limit the movement of the first wedge plate 8, preventing it from rotating or deviating. The other end of the first connecting rod 13 is slidably inserted into the interior of the third rectangular post 26. The sliding cooperation between the first connecting rod 13 and the third rectangular post 26 can drive the third rectangular post 26 to move synchronously when the first wedge plate 8 moves up and down. As a preferred solution, the third rectangular post 26 and the rectangular frame 4 can be connected by an elastic element to further increase the power when the third rectangular post 26 is reset downward.

[0031] Working principle When the patient needs to defecate, simply control the dual-axis motor 20 to rotate forward. Since the threads on the two threaded rods 21 are in opposite directions, under the drive of the dual-axis motor 20, the two threaded rods 21 rotate synchronously and drive the two threaded plates 22 to move outward simultaneously along the axis of the threaded rods 21. When the threaded plates 22 move, they drive the first moving plate 6 to slide outward synchronously within the rectangular frame 4 through the second connecting rod 23. The first moving plate 6 is fixedly connected to the baffle 5, which in turn drives the two baffles 5 to slide into the receiving groove of the bed body 1, gradually opening the excretion groove 3. At the same time, the fourth wedge plate 17 on the first moving plate 6 moves outward synchronously with the first moving plate 6, and the second moving plate 11 and the third wedge plate 16 move horizontally synchronously with the baffle 5. The first wedge plate 8 and the flexible plate 9 also move outward and compress the first spring 7.

[0032] When the second rectangular column 15 moves to contact the vertical plate 18, the vertical plate 18 blocks the second rectangular column 15, preventing the second rectangular column 15 and the second moving plate 11 from continuing to move horizontally. At this time, the dual-axis motor 20 continues to drive the first moving plate 6 to move outward. The fourth wedge plate 17 on the first moving plate 6 moves accordingly and presses the inclined surface of the third wedge plate 16. Due to the change in the direction of the force generated by the inclined surface, the third wedge plate 16 is subjected to an upward force, which in turn drives the second rectangular column 15, the second moving plate 11, and the second wedge plate 14, the first wedge plate 8 and the flexible plate 9 associated with the second moving plate 11 to move upward synchronously. During this process, the second spring 12 is compressed.

[0033] When the flexible plate 9 moves upward to contact the patient's buttocks, the second moving plate 11 continues to move upward under the continuous pressure of the fourth wedge plate 17. At this time, the inclined surface of the second wedge plate 14 interacts with the inclined surface of the first wedge plate 8. When the second wedge plate 14 moves upward, it generates a horizontal outward pushing force on the first wedge plate 8, which drives the two first wedge plates 8 and the flexible plate 9 to move outward at the same time and further compress the first spring 7. During the outward movement of the two flexible plates 9, the patient's buttocks can be automatically opened, so that the anus and perianal area are fully exposed, and the patient can defecate smoothly. The excrement falls into the toilet 2 below through the opened excretion channel 3 and rectangular frame 4.

[0034] After defecation, the toilet 2 automatically activates the cleaning function to rinse the patient's perianal area. After rinsing, the drying function is activated to dry the perianal skin, ensuring the patient's cleanliness and comfort. Subsequently, the dual-axis motor 20 is reversed, and the two threaded rods 21 rotate in opposite directions, driving the two threaded plates 22 to move closer to each other. Through the second connecting rod 23, the first moving plate 6 and the fourth wedge plate 17 are pulled inward simultaneously. The squeezing force of the fourth wedge plate 17 on the third wedge plate 16 disappears, and the second spring 12 returns to its elastic deformation, driving the second moving plate 11, the second rectangular column 15, and the third wedge plate 16 to reset downward. At the same time, under the action of gravity and elastic elements, the first wedge plate 8 and the flexible plate 9 reset, and the first moving plate 6 continues to move inward, driving the baffle 5 to slide out of the receiving groove and re-close the excretion groove 3 until all components return to their initial positions, and the bed surface returns to flat so that the patient can lie down normally and wait for the next use.

[0035] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the scope of protection of this invention.
