Description

Technical Field

[0001] This utility model belongs to the field of nursing equipment, specifically relating to a buttock-opening mechanism, a nursing device for assisting excretion, and a nursing bed. Background Technology

[0002] With the accelerating aging of the population, the number of disabled elderly people in my country is increasing year by year. Due to the decline and loss of physical functions, disabled elderly people are unable to take care of themselves and require daily care from caregivers. However, caregiving work is complicated and chaotic, and the difficulty and burden of care are relatively large.

[0003] Because most disabled elderly people are bedridden for extended periods and unable to perform excretion independently, and the timing and frequency of their bowel movements are unpredictable, they often require external assistance. Currently, assisted excretion methods are relatively simple, mostly involving placing bedpans, diaper pads, or other similar devices under the elderly person to collect waste. However, this method requires frequent changes of these devices, leading to a heavy workload and cumbersome procedures for caregivers, placing a significant burden on them. Furthermore, leakage during changes can easily occur, contaminating bed sheets, blankets, clothing, and the elderly person's body, causing discomfort and adding extra cleaning work.

[0004] Currently, while some related excretory care devices or beds are available on the market, their main function is to align the elderly person's excretory organs with the corresponding collection structure, allowing the elderly person to complete excretion on their own, followed by collection, cleaning, and treatment of the excrement. However, these devices and beds generally have a significant drawback: they do not consider the situation where disabled elderly people cannot separate their buttocks independently. This results in the elderly person excreting without full exposure of the anus and perianal area, affecting not only the smoothness of excretion but also increasing the difficulty of subsequent cleaning, failing to meet the excretory care needs of disabled elderly people. Therefore, there is an urgent need for a buttock-opening mechanism or care device that can solve the above problems. Utility Model Content

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to the following embodiments.

[0026] Example 1: See attached Figure 1In a first aspect, this embodiment provides a buttock-opening mechanism, including a guide rail 1, a controller, and two buttock-opening units. Each buttock-opening unit includes a panel assembly 2 and a movable support structure 3. The panel assembly 2 is detachably mounted above the movable support structure 3. The panel assembly 2 includes at least a flexible panel 21 for close contact with the user's buttocks. The movable support structure 3 includes at least a horizontal movement component 31. Both horizontal movement components 31 are slidably connected to the guide rail 1 and can slide in the left-right direction. The controller is used to synchronously drive the two horizontal movement components 31 to move away from or closer to each other, indirectly driving the two flexible panels 21 to simultaneously open or close the user's left and right buttock flaps to expose or cover the user's anus and surrounding area. As can be seen from the above structure, the two buttock-opening units are used to open the user's left and right buttock flaps respectively. The buttock-opening unit includes a panel assembly 2 and a movable support structure 3, wherein the panel assembly 2 is detachably mounted above the movable support structure 3, facilitating the disassembly, cleaning, or replacement of different models of the panel assembly 2 to accommodate users with different buttock sizes and shapes. The panel assembly 2 includes at least a flexible panel 21, which has a certain deformation capability. Specifically, the flexible panel 21 may have a recessed portion that can contact and fit snugly against the user's buttocks. The movable support structure 3 includes at least two horizontal movement components 31; both horizontal movement components 31 are slidably connected to the guide rail 1 and can slide in the left-right direction. The controller is electrically connected to the two horizontal movement components 31 respectively and can actively control the two horizontal movement components 31 to move away from or towards each other in the horizontal left or right direction, adjusting the distance between the two flexible panels 21 that are already snugly against the user's buttocks, thereby opening or closing the user's buttocks, thus exposing or covering the user's anus and surrounding area. The connection between the controller and the two horizontal movement components 31 can be wired or wireless, or a terminal can be used for connection and control. Since the connection method and control-related technology are existing technologies, they will not be described in detail in this utility model. When the buttocks need to be opened, the caregiver can ensure that the user's buttocks are tightly fitted against the recesses of the two flexible panels 21. Then, using the controller, the two horizontal movement components 31 are moved away from each other, indirectly causing the two flexible panels 21 to open the user's left and right buttocks, exposing the anus and surrounding area to assist with defecation. During defecation, a urinal or other excretion care tools can be used to collect and process excrement, while also keeping the anus and surrounding area continuously exposed to air, facilitating cleaning and thorough drying by the caregiver. After the procedure, the caregiver can use the controller again to bring the two horizontal movement components 31 closer together, closing the user's left and right buttocks. Furthermore, before using the buttocks opening mechanism of this invention, the caregiver can adjust the distance between the two flexible panels 21 to adjust the user's buttock position, further ensuring comfort.This invention allows the user's anus and perianal area to be fully exposed through a buttock-opening operation, ensuring smooth defecation and facilitating subsequent cleaning. Different models and sizes of flexible panels 21 can be replaced as needed to accommodate different users' buttock sizes.

[0027] Example 2: See attached Figures 1-3 Based on Embodiment 1, it also includes a base plate 4; the guide rail 1 is disposed on the base plate 4; the horizontal motion component 31 includes a first moving component 311 and a horizontal motor 312; the first moving component 311 is slidably connected to the guide rail 1; the bottom of the horizontal motor 312 is fixedly connected to the base plate 4, and the output end of the horizontal motor 312 is driven and connected to the first moving component 311; the controller is electrically connected to the horizontal motor 312. From the above structure, it can be seen that the base plate 4 serves as the carrier for the fixed installation of the guide rail 1, so that the guide rail 1 is fixedly connected above the base plate 4. The first moving component 311 is slidably connected to the guide rail 1, and can move along the length direction of the guide rail 1, i.e., attached to... Figure 2 The horizontal motor 312 drives the first moving part 311 to move in the left and right directions. Specifically, the bottom of the horizontal motor 312 is fixed to the base plate 4, and the horizontal motor 312 fixes its own position to ensure the stability of the output power. The horizontal motor 312 can be a horizontal stepper motor, which uses its built-in flange drive plate to convert the rotational motion into linear motion. The output end of the horizontal motor 312 is connected to the drive of the first moving part 311 to drive the first moving part 311 to move linearly to the left or right horizontally. The controller is electrically connected to the horizontal motor 312 and is used to indirectly drive the two first moving parts 311 to move relatively closer or further apart in the horizontal direction by controlling the start, stop, rotation direction and speed of the two horizontal motors 312 in the two pivoting units.

[0028] The movable support structure 3 further includes a vertical motion component 32; the vertical motion component 32 includes a second moving part 321, a guide component, and a vertical motor 322; the second moving part 321 is movably connected above the first moving part 311 through the guide component; the guide component is used to guide the second moving part 321 to move vertically; the bottom of the vertical motor 322 is fixedly connected to the base plate 4, and the output end of the vertical motor 322 passes through the first moving part 311 and is driven and connected to the second moving part 321; the controller is electrically connected to the vertical motor 322. As can be seen from the above structure, this utility model indirectly drives the panel assembly 2 to move vertically by driving the second moving part 321 to rise and fall, in order to adapt to users of different body types and meet the height requirements required for the user's buttocks to fit against the flexible panel 21 under the same or different usage scenarios, so that the two flexible panels 21 can fit tightly against the user's left and right buttocks and ensure smooth subsequent buttock-bending operations. Specifically, the bottom of the vertical motor 322 is fixedly connected to the base plate 4, thus fixing its position and ensuring the stability of its power output. The vertical motor 322 can be a vertical stepper motor, which uses its built-in flange drive plate to convert rotary motion into linear motion. The output end of the vertical motor 322 passes through the first moving part 311 and is connected to the second moving part 321 to drive the second moving part 321 to move vertically up and down. Furthermore, a guide assembly provides vertical guidance when the second moving part 321 moves vertically, preventing deviation or swaying during lifting and lowering, and ensuring the stability of the equipment. The controller is also electrically connected to the vertical motor 322 and indirectly drives the two second moving parts 321 to move vertically synchronously by controlling the start, stop, rotation direction, and speed of the two vertical motors 322 in the two lifting units.

[0029] The guiding assembly includes two vertical guide rods 323 and two linear bearings 324. The two vertical guide rods 323 are symmetrically arranged on the front and rear sides of the top surface of the first moving member 311. The vertical guide rods 323 pass through the second moving member 321 upwards and continue to extend. The two linear bearings 324 are symmetrically arranged on the front and rear sides of the top surface of the second moving member 321. The linear bearings 324 have guide holes. The guide holes correspond one-to-one with the vertical guide rods 323, and the vertical guide rods 323 fit into them. From the above structure, it can be seen that the linear bearings 324 are fixed on the top surface of the second moving member 321, and the guide holes in the linear bearings 324 are passed through by the corresponding vertical guide rods 323. After passing through the second moving member 321 and the vertical guide rods 323, the vertical guide rods 323 continue to extend vertically upwards. When the second moving part 321 is lifted and lowered under the drive of the vertical motor 322, the two linear bearings 324 will also lift and lower synchronously with the second moving part 321. At this time, the vertical guide rod 323 will guide and restrict the second moving part 321 to slide vertically upward or downward along it, so as to avoid the second moving part 321 from deviating or shaking during lifting and lowering, thereby ensuring the stability of the panel assembly 2 during lifting and lowering.

[0030] The system also includes multiple photoelectric sensor switches 33; these switches 33 are mounted on the vertical motor 322 and / or the horizontal motor 312; the controller is also electrically connected to the multiple photoelectric sensor switches 33. As can be seen from the above structure, the photoelectric sensor switches 33 in this invention can determine whether the first moving member 311 and / or the second moving member 321 has returned to their initial horizontal and / or vertical positions before use after completing the hip-bending operation by detecting whether the light from the light-sensing components mounted on them is blocked. When the first moving member 311 and / or the second moving member 321 returns to their initial positions, the light from the photoelectric sensor switches 33 is blocked, and a blocking signal is sent to the controller, causing the controller to stop the vertical motor 322 and / or the horizontal motor 312, thus completing the reset.

[0031] The panel assembly 2 further includes a bracket 22 and a first strong magnet 23; the flexible panel 21 is detachably disposed above the bracket 22; the top surface of the flexible panel 21 is coated with a silicone gel layer; the top of the bracket 22 matches the shape of the flexible panel 21, and the bottom is fitted with the first strong magnet 23; the movable support structure 3 further includes a support rod 34; the support rod 34 is disposed on the top surface of the second moving part 321 and extends upward; the top of the support rod 34 is also provided with a second strong magnet 341; the second strong magnet 341 has opposite magnetic poles to the first strong magnet 23, and the connection between the bracket 22 and the support rod 34 is achieved through magnetic attraction with the first strong magnet 23. As can be seen from the above structure, the flexible panel 21 is detachably disposed above the bracket 22, making it convenient for caregivers to disassemble, clean, or replace the flexible panel 21 individually to maintain its cleanliness and hygiene. The top surface of the flexible panel 21 is coated with a silicone gel layer. This silicone gel layer is skin-friendly and possesses elasticity and adhesiveness, ensuring a tight fit and adhesion between the flexible panel 21 and the user's buttocks during use, facilitating subsequent buttock-bending operations. The top of the bracket 22 matches the shape of the flexible panel 21, facilitating its installation. A first strong magnet 23 is fitted to the bottom of the bracket 22, magnetically engaging with a second strong magnet 341 at the top of the support rod 34, thus connecting the bracket 22 and the support rod 34. Furthermore, by disengaging the magnetic engagement between the first strong magnet 23 and the second strong magnet 341, the panel assembly 2 and the support rod 34 can be quickly disassembled. Caregivers can choose to replace only the flexible panel 21 or replace the flexible panel 21 along with the bracket 22 for cleaning, depending on their needs.

[0032] Preferably, the panel assembly 2 is further connected to a negative pressure adsorption mechanism; the negative pressure adsorption mechanism is used to provide negative pressure adsorption force to the flexible panel 21. Specifically, the negative pressure adsorption mechanism includes a pipe and a vacuum pump, one end of the pipe is connected to the top wall of the flexible panel 21, and the other end is connected to the vacuum pump. After the flexible panel 21 is in contact with the user's buttocks, the vacuum pump is turned on, which provides a downward negative pressure adsorption force to the flexible panel 21, thereby increasing the adsorption force on the user's buttocks skin and ensuring the success rate of the buttock-bending operation.

[0033] Preferably, the horizontal sliding range of the first moving part 311 driven by the horizontal motor 312 in the horizontal direction is preferably 0mm-40mm, and the vertical lifting range of the second moving part 321 driven by the vertical motor 322 in the vertical direction is preferably 0mm-30mm. This range setting can meet the needs of users with different body types, such as users who are thin, overweight, or have a large distance between their buttocks. The limitation on the maximum horizontal sliding distance can also prevent excessive buttock bending, preventing unnecessary damage to the user's buttock muscles and skin due to excessive traction, and ensuring safety during use. The limitation on the maximum height is to prevent the buttocks from being positioned too high, which would cause discomfort to the user and ensure comfort during use.

[0034] Example 3: See attached Figures 1-4 This embodiment provides a nursing device for assisting excretion. This device employs the buttock-opening mechanism provided in Embodiment 2 and includes a housing 5 and an excretion host 6. The housing 5 is hollow inside, partially accommodating the movable support structure 3, allowing the panel assembly 2 to be supported above the housing 5 via the movable support structure 3, with the flexible panel 21 exposed. The excretion host 6 is connected to the central area of ​​the top of the housing 5. The excretion host 6 has an excretion groove 61. Two flexible panels 21 are symmetrically arranged on the left and right sides of the excretion groove 61. As can be seen from the above structure, the housing 5 serves as the mounting base for the excretion host 6 and the buttock-opening mechanism. Its hollow interior partially accommodates the movable support structure 3, allowing the panel assembly 2 to be supported above the housing 5 via the movable support structure 3, while exposing the flexible panel 21 outside the housing 5 for easy contact with the user's buttocks. Specifically, the movable support structure 3, except for the support rod 34 connected to the panel assembly 2, is located inside the housing 5. The controller can also be located inside or outside the housing 5 according to actual installation requirements. The excretion unit 6 is existing technology and can integrate existing functions such as collecting and processing excrement and cleaning the genitals according to actual needs. In use, the user's anus and surrounding area are aligned and placed into the excretion trough 61. However, ordinary excretion units 6 do not have a buttock-opening function. Therefore, this invention symmetrically arranges two flexible panels 21 on the left and right sides of the excretion trough 61. In use, the two flexible panels 21 are first tightly fitted to the user's left and right buttocks, respectively. Then, the controller drives the movable support structure 3 to move away horizontally, thereby causing the two flexible panels 21 to open the user's left and right buttocks horizontally, fully exposing the anus and surrounding area and aligning it with the excretion trough 61, ensuring accurate excretion positioning and a smooth excretion process. After excretion, the buttocks remain open, and this area remains exposed to the excretion trough 61, facilitating cleaning by the excretion unit 6 and improving cleanliness.

[0035] The base plate 4 is connected to the bottom of the outer shell 5; it also includes a displacement slide rail 7; the lower side of the base plate 4 is slidably connected to the displacement slide rail 7, and can reciprocate along the length of the displacement slide rail 7. As can be seen from the above structure, the base plate 4 is connected to the bottom of the outer shell 5, which on the one hand provides an installation base for the movable support structure 3, and on the other hand, the lower side of the base plate 4 is slidably connected to the displacement slide rail 7, which can drive the entire device to reciprocate along the length of the displacement slide rail 7. The displacement slide rail 7 can be placed or fixed in the required position and remain stationary, such as on a bed or on the ground. While meeting the usage requirements, there is no need to move the entire device back and forth. It can be moved away by bringing the sliding device closer to the user or after use.

[0036] Preferably, a recessed area 51 is provided on each of the left and right sides of the top surface of the outer shell 5; the two recessed areas 51 correspond one-to-one with the two flexible panels 21. As can be seen from the above structure, the recessed area 51 is concave downwards. To accommodate the horizontal displacement requirements of the flexible panel 21, the side away from the main exhaust unit 6 can penetrate through the left or right side wall of the outer shell 5, forming a lateral open structure. This allows the flexible panel 21 to move smoothly into or out of the recessed area 51 during horizontal movement without being obstructed by the outer shell 5, ensuring smooth movement. In addition, the recessed area 51 can also be provided with a waist-shaped hole through which the support rod 34 can pass and move horizontally, further ensuring that the movable support structure 3 can move smoothly horizontally and / or vertically.

[0037] Example 4: See attached Figures 1-6 This embodiment provides a nursing bed that uses the auxiliary excretion nursing device as provided in Embodiment 3.

[0038] A nursing bed includes a bed frame and a nursing device for assisting with excretion; the nursing device for assisting with excretion is installed on the bed frame. As can be seen from the above structure, the aforementioned nursing device for assisting with excretion can be conveniently used simply by being installed on the bed frame. Depending on the usage requirements, the installation method of the nursing device for assisting with excretion can adopt existing and conventional installation methods such as detachable installation or fixed installation. Specific technical means can be found in existing technologies, and therefore will not be elaborated here.

[0039] Preferably, the system also includes a modular mattress 8 composed of several mattress pieces; these pieces have the same or different dimensions; the modular mattress 8 fits onto the bed frame, with a gap 9 provided to accommodate a nursing device for assisting with excretion. As can be seen from the above structure, this installation method can be used in practice. Without altering the bed frame structure, a modular mattress 8 composed of multiple mattress pieces is added, leaving a gap 9 to match the shape of the nursing device for assisting with excretion. The device is then placed inside to complete the installation. Because the mattress pieces have the same or different dimensions, it can flexibly adapt to various bed sizes, making it widely applicable and highly practical. It can be easily adapted to both ordinary family beds and beds used in nursing homes, providing convenience for users, especially disabled elderly people, in their excretion care.
