Description

Technical Field

[0001] The invention relates to the field of nursing beds for defecation and urination, and in particular to a nursing bed for defecation and urination and a method. Background Art

[0002] With the continuous advancement of medical technology and the intensification of the aging trend of the population, nursing beds for both defecation and urination, as important medical equipment, play an increasingly important role in medical institutions and home care. Most traditional nursing beds only provide basic lying functions, and for patients who need to stay in bed for a long time, especially those with incontinence or mobility difficulties, their excretion and cleaning problems have always been the difficulties and pain points in nursing. In order to solve these problems, a series of nursing beds for both defecation and urination with richer functions and more humanized designs have gradually emerged on the market. On the basis of retaining basic functions, nursing beds have added advanced functions such as automatic turning over, lifting, and automatic replacement of bedpans, aiming to improve the comfort and quality of care for patients. Among them, some high-end nursing beds are also equipped with intelligent sensing systems and flushing devices, which can automatically detect the patient's excretion needs and handle them accordingly, reducing the burden on caregivers.

[0003] The existing two-defecation nursing bed still has certain deficiencies in the design of the flushing device. Although some nursing beds are equipped with flushing devices, they can only simply flush the bedpan and cannot fully clean the patient's body. This not only affects the patient's comfort, but may also pose a potential threat to the patient's skin health. In addition, the current flushing system has a poor cleaning effect on the bedpan itself. At present, when cleaning the bedpan, it mostly relies on the water spray element embedded in the bedpan for flushing. However, with the installation of the water spray element, there will be a cleaning dead angle at its installation position, resulting in poor cleaning effect at the installation position of the water spray element. Reducing the installation of the water spray element on the bedpan requires increasing the cleaning range of a single water spray element, which requires increasing the water pressure and is more likely to cause splashing and overflowing problems, affecting the hygiene and safety of the two-defecation nursing bed. Summary of the invention

[0004] The purpose of the present invention is to provide a two-toilet nursing bed and method in view of the defects existing in the prior art, wherein a human body flushing component and a cover flushing component are installed on the bedpan to clean the patient's body on the bedpan and the bedpan cover of the bedpan, and a basin flushing component is installed on the side of the bedpan cover away from the contact with the human body. After the bedpan cover is closed to block the opening at the top of the bedpan, the bedpan is flushed with the basin flushing component. By distributing the nozzles on the circumferential side of the bedpan cover, the bedpan cover and the bedpan can be cleaned in all directions, avoiding the problem of cleaning dead corners. The nozzles adjust their directions as the bracket and the bedpan cover rotate, ensuring uniformity and comprehensiveness of cleaning. Since the nozzles are distributed on the circumferential side of the bedpan cover instead of being concentrated inside the bedpan, even if the water pressure is increased, no obvious splashing and overflowing problems will occur, and the risk of splashing and overflowing can be further reduced by accurately controlling the water spraying amount and water spraying time of the nozzles.

DETAILED DESCRIPTION

[0030] Example 1 In a typical embodiment of the present invention, Figure 1 -, shown in 12, a defecation and urination care bed is provided.

[0031] In this embodiment, Figure 1 As shown, the nursing bed for defecation and bowel movement includes an auxiliary turning system 1, a back-lifting system 2 and a flushing system 3. The auxiliary turning system 1 and the back-lifting system 2 are both used to adjust the posture of the user carried thereon through the bed board 6. The flushing system 3 can receive and process the defecation of the user while lying in bed, and can realize self-cleaning of the flushing system 3.

[0032] Specific, combined Figure 1-Figure 12The nursing bed for both toilet and urination includes a bed frame 4, a floating frame 5, a bed board 6, a bedpan 301 and a flushing assembly. The bed frame 4 serves as the basic supporting structure of the entire nursing bed and provides a platform for installation and fixing of other components. The floating frame 5 is rotatably mounted on the bed frame 4 and rotated by the drive of the telescopic rod 102, thereby driving the rotation of the bed board 6 and the bedpan 301. The nursing bed is allowed to adjust its angle when necessary, which is convenient for the care and cleaning of the patient. The bed board 6 is laid and connected to the floating frame 5, and is provided with holes for the installation of the bedpan 301. The bed board 6 provides a comfortable lying surface for the patient. The bedpan 301 is installed below the hole of the bed board 6 to form a cavity 304 with an opening at the top. The bedpan 301 is a collection device for excrement, and its design needs to consider easy cleaning and avoidance of leakage. The bedpan cover 306 is rotatably connected to the bedpan 301, and is used to flip and probe into the cavity 304 or block the opening of the cavity 304. The design of the bedpan cover 306 needs to ensure sealing to prevent the spread of odor and germs. The flushing assembly includes a cover flushing assembly 302 and a body flushing assembly 303, which are installed in the bedpan 301 and on the bedpan cover 306, respectively, and are used to clean the bedpan cover 306 and the patient's body. In addition, a nozzle is provided on the side of the bedpan cover 306 that is away from the human body, which is used to flush the bedpan 301 when the bedpan cover 306 is closed. The nozzles are distributed on the circumferential side of the bedpan cover 306, connected to the bedpan cover 306 through a bracket, and the direction can be adjusted by rotating the bedpan cover 306. The design of the nozzle must ensure uniformity and comprehensiveness of cleaning, while avoiding the risk of splashing and overflow.

[0033] Although the nursing bed in the prior art has the function of assisting the user to turn over, in actual use, the connecting frame is driven by a single-sided turning electric push rod, resulting in poor smoothness when driving the floating frame 5 to turn over. In addition, the single-sided turning electric push rod has poor ability to maintain the posture of the floating frame 5 after the floating frame 5 has turned over, and the floating frame 5 is prone to shaking.

[0034] Based on this, Figure 4-Figure 5 As shown, this embodiment utilizes the auxiliary turning system 1 to drive the floating frame 5 to rotate relative to the bed frame 4 through the telescopic movement of the telescopic rod 102, thereby realizing the auxiliary turning of the user. The two ends of the floating frame 5 are rotatably connected to the support rod 103 through the support, and the bottom of the support rod 103 is fixed to the bed frame 4, which enhances the overall stability of the nursing bed. The support rods 103 on both sides are used to constrain the floating frame 5 in both the forward and reverse directions to improve the stability of the floating frame 5, so as to improve the posture maintenance ability of the telescopic rod 102 on the floating frame 5, thereby reducing the shaking of the floating frame 5, reducing the risk of use, and ensuring the safety of the user during the turning process.

[0035] like Figure 4As shown, the auxiliary turning system 1 includes a bed frame 4, a floating frame 5, a bed board 6 and a telescopic rod 102. Among them, the bed frame 4 is a frame structure, which includes a bed side rod 101 located on both sides and a support rod 103 located at both ends, and a limiter 107 is provided on the bed side rod 101. The bed frame 4 provides a stable support foundation for the entire nursing bed. The floating frame 5 is a frame structure, located between the bed side rods 101 on both sides of the bed frame 4, and the two ends are rotatably mounted on the support rod 103. The rotation axis of the floating frame 5 is parallel to the connecting line at the two ends of the bed frame 4, so that the floating frame 5 can rotate smoothly relative to the bed frame 4. The two sides of the floating frame 5 are rotatably connected to the bed frame 4 through the telescopic rod 102, and the floating frame 5 can be driven by the driving force from both sides, which improves the smoothness and stability of the rotation.

[0036] like Figure 5 As shown, the bed board 6 includes a lower body bed board 6 and an upper body bed board 6, the lower body bed board 6 is installed on the floating frame 5, the upper body bed board 6 includes a back bed board 201 and a back side board 202, the back bed board 201 is hinged with back side boards 202 on both sides, the back bed board 201 is connected to the floating frame 5 through a connecting rod mechanism, so that the upper body bed board 6 can rotate relative to the floating frame 5; the lower body bed board 6 includes a lower body middle board 109 and a lower body side board 108 hinged on both sides of the lower body middle board 109, the lower body middle board 109 and the back bed board 201 together serve as the middle board 109, and the lower body side board 108 and the back side board 202 together serve as the side board 108.

[0037] In the description of the auxiliary turning system 1 of this embodiment, for the sake of convenience, the bed board 6 is described as a middle board 109 and side boards 108 hinged on both sides of the middle board 109. The middle board 109 is laid on and connected to the floating frame 5, and flips along with the flipping of the floating frame 5, so as to adjust the inclination angle of the body of the user thereon, and the side boards 108 are overlapped with the limiting pieces 107 on the corresponding side bed side bars 101 and can move relatively.

[0038] When the user needs to be assisted to turn over, the telescopic rod 102 starts to work. One end of the telescopic rod 102 is connected to the bed frame 4, and the other end is rotatably connected to the floating frame 5. Through the telescopic movement of the telescopic rod 102, the floating frame 5 is driven to rotate around its rotation axis relative to the bed frame 4. When the telescopic rod 102 on the same side of a side plate 108 is shortened and the telescopic rod 102 on the opposite side is extended, the limiter 107 overlapped by the side plate 108 can support one side of the side plate 108, limit the movement range of the side plate 108 to prevent the side plate 108 from falling, and make the side plate 108 tilt; while the other side plate 108 follows the middle plate 109 and the floating frame 5 to tilt. The rotation axis of the side plate 108 relative to the middle plate 109 is parallel to the rotation axis of the floating frame 5, so that the bed board 6 can be turned over accordingly with the rotation of the floating frame 5.

[0039] like Figure 5As shown, when the floating frame 5 rotates to the required angle, the telescopic rod 102 stops working. At this time, the user's side body is stressed, which relieves the pressure on the user's back and reduces the occurrence of bedsores. At the same time, the user can turn over with the help of medical staff. The side plate 108 remains in the same relative position under the restriction of the limiter 107 to ensure the safety of the user. The floating frame 5 is driven to rotate by the telescopic rods 102 on both sides at the same time, thus avoiding the problem of poor smoothness caused by unilateral driving. The support rods 103 on both sides constrain the floating frame 5 in both the forward and reverse directions, thus improving the stability of the floating frame 5, thereby enhancing the telescopic rods 102's ability to maintain the posture of the floating frame 5. By reducing the shaking of the floating frame 5, the probability of squeezing injury due to shaking at the gap between the bed board 6 and the fixed bed frame 4 is reduced, thereby reducing the risk of use.

[0040] like Figure 5 As shown, one side of the side plate 108 is hinged to the middle plate 109, and the side plate 108 can rotate at a certain angle relative to the middle plate 109 to adapt to the flipping action of the floating frame 5. The other side of the side plate 108 away from the middle plate 109 is provided with a load-bearing wheel 111, which enables the side plate 108 to move smoothly along the stopper 107 when the floating frame 5 flips, while maintaining contact with the middle plate 109 and the bed side rod 101, and still has load-bearing capacity when the side plate 108 is tilted to prevent the user from slipping.

[0041] like Figure 5 As shown, the limiter 107 is a guide groove plate extending to the inner side of the bed frame 4 to form a cantilever structure, providing a running track for the load-bearing wheel 111, avoiding the problem of the load-bearing wheel 111 being offset and sliding, and ensuring the stability and safety of the side plate 108 during the flipping process. The guide groove plate is separated from the floating frame 5, avoiding collision and interference with the floating frame 5, ensuring the smoothness of the flipping process, and avoiding the problem of jamming and obstruction.

[0042] Along the axial direction of the bed side bar 101, a plurality of load-bearing wheels 111 are sequentially installed on the side plate 108 at intervals, which increases the contact points between the side plate 108 and the stopper 107, and improves the stability and reliability of the movement of the side plate 108. The bed side bar 101 is provided with a plurality of stoppers 107 corresponding to the load-bearing wheels 111 on the same side side plate 108, ensuring that each load-bearing wheel 111 has a corresponding track to follow, thereby enhancing the stability and safety of the structure.

[0043] like Figure 4 and Figure 5 As shown, both ends of the floating frame 5 are rotatably connected to the support rod 103 through the support, so as to meet the requirement of the floating frame 5 to flip relative to the support rod 103, and realize the flipping function of the bed board 6. The support is located below the floating frame 5, providing a stable support point for the floating frame 5.

[0044] like Figure 4 As shown, the bottom of the support rod 103 is fixed to the bed frame 4, ensuring the stability and firmness of the support rod 103. The side of the support rod 103 is connected with a rib fixed to the bed frame 4, which enhances the strength and stability of the support rod 103 and prevents shaking or deformation caused by the flipping action.

[0045] One end of the telescopic rod 102 is connected to the side frame of the floating frame 5 through a hinge, and the other end is connected to the bed frame 4 through a hinge, allowing the telescopic rod 102 to flexibly adjust the length and angle when driving the floating frame 5 to flip. The telescopic rod 102 is tilted relative to the support rod 103, and the telescopic rod 102 can generate a larger torque when driving the floating frame 5 to flip, thereby improving the flipping efficiency. The telescopic rods 102 on both sides of the support rod 103 are connected to the same end of the floating frame 5, ensuring that the telescopic rods 102 on both sides can work together to maintain the stability and coordination of the flipping of the floating frame 5.

[0046] In this embodiment, the telescopic rod 102 can adopt a linear telescopic element such as an electric cylinder or a hydraulic cylinder. The telescopic rods 102 on both sides of the support rod 103 can move in coordination to improve the smoothness of the floating frame 5 during the flipping process and jointly maintain the stability of the floating frame 5 after the flipping adjustment.

[0047] A crossbeam 112 is connected between the two sides of the bed frame 4, which not only enhances the overall strength and stability of the bed frame 4, but also provides additional support points for the support rod 103 and the telescopic rod 102. The crossbeam 112 is located below the floating frame 5, avoiding direct contact with the floating frame 5 and reducing interference during the flipping and use of the floating frame 5.

[0048] like Figure 5 As shown, a toilet hole 3053 is provided on the middle plate 109 of the bed plate 6, which is convenient for the user's excretion needs. A toilet bowl 301 is arranged under the toilet hole 3053 to collect excrement, keeping the bed plate 6 clean and hygienic.

[0049] The auxiliary turning function of the bed board 6 is realized, meeting the turning needs of long-term bedridden users. The stability and safety of the bed board 6 are improved, preventing the user from slipping or getting injured during the turning process. The structural design of the bed board 6 is optimized, and the turning efficiency and comfort are improved.

[0050] refer to Figure 4 and Figure 5 The working process of the auxiliary turning system 1 is as follows. Turning process: When the user needs to be assisted to turn over, the telescopic rod 102 is activated to push the floating frame 5 to turn left or right around its rotation axis (ie, the axis of the support rod 103 ).

[0051] When the floating frame 5 turns over, the middle plate 109 tilts accordingly, driving the user to tilt to one side.

[0052] The side panels 108 slide along the guide grooves under the action of their own weight and the load-bearing wheels 111. The side panels 108 on the lower side form a certain angle (similar to a V-shaped angle) with the middle panel 109 under the support of the side frame of the floating frame 5, playing a protective role to prevent the user from sliding off the side of the bed board 6. Figure 5 shown.

[0053] At the same time, under the load-bearing effect of the side frame of the floating frame 5, the side panel 108 on the higher side remains coplanar with the middle panel 109 and tilts along with the middle panel 109 and the floating frame 5, maintaining relatively smooth movement to avoid safety risks caused by the width of the space for the user to lie down and sleep being too small or empty.

[0054] Reset process: After the turning over is completed, the telescopic rod 102 moves in the reverse direction, driving the floating frame 5 to return to the horizontal state.

[0055] The side plate 108 on the lower side is also restored to a horizontal state consistent with the middle plate 109 under the guidance of the load-bearing wheel 111 and the guide groove plate, and the side plate 108 on the other side remains coplanar with the middle plate 109 and restores to a horizontal state, as shown in FIG. 4 .

[0056] The auxiliary turning system 1 effectively prevents the risk of the user sliding off the side of the bed board 6 during turning over by designing the side panels 108 and the guide groove panels, thereby improving safety. The floating frame 5 is rotatably connected to the bed frame 4 through the telescopic rod 102, so as to realize flexible turning over actions and meet the needs of different users.

[0057] The auxiliary turning system 1 in this embodiment is simplified in structure and working mode, but still has the functions of assisting turning and protection. Moreover, the relative movement and support of the side plate 108 are realized by the design of the load-bearing wheel 111 and the guide groove plate, and the support rods 103 on both sides are used to constrain the floating frame 5 in both the forward and reverse directions, thereby improving the stability of the floating frame 5 and improving the posture maintenance ability of the telescopic rod 102 on the floating frame 5, thereby reducing the shaking of the floating frame 5 and reducing the risk of use.

[0058] The main function of the nursing bed with back-lifting protection function in the prior art is to assist the user lying on the bed to change from a lying position to a sitting position, by driving the back-lifting frame to rotate around the rotating shaft 212 through the back-lifting power unit, thereby driving the back bed board 201 to rotate and lift upward relative to the hip bed board 6; however, when the inclination angle of the back bed board 201 is small (such as the commonly used inclination angle of 30°), the groove formed by the back side panel 202 after rotating relative to the back bed board 201 is shallow, resulting in poor protection capability.

[0059] In this embodiment, Figure 2 and Figure 3As shown, the back-lifting system 2 is provided with a wedge block 210 on the back side panel 202 to cooperate with the pulley 208 at the end of the side bracket 207. The pulley 208 increases the distance from the back side panel 202 during the movement along the wedge block 210, thereby increasing the flipping amount of the back side panel 202 relative to the back bed board 201, and increasing the depth of the groove formed by the back bed board 201 and the back side panel 202, thereby improving the protective capability.

[0060] like Figure 2 As shown, the back-lifting system 2 mainly includes a floating frame 5, a bed board 6 and a back-lifting assembly, and the floating frame 5 serves as the basic supporting structure of the entire back-lifting system 2. The bed board 6 includes a lower body bed board 6 and an upper body bed board 6. The lower body bed board 6 is installed on the floating frame 5, and the upper body bed board 6 includes a back bed board 201 and a back side board 202. The back bed board 201 is hinged with a back side board 202 on both sides, so that the back side board 202 can rotate relative to the back bed board 201. The back bed board 201 is connected to the floating frame 5 through a connecting rod mechanism, so that the upper body bed board 6 can rotate relative to the floating frame 5, thereby changing the angle between the back bed board 201 and the lower body bed board 6.

[0061] like Figure 2 As shown, the back-lifting assembly is a driving assembly that drives the upper body bed board 6 to rotate relative to the lower body bed board 6. The back-lifting assembly includes a main bracket 203 and a side bracket 207 connected to the main bracket 203. One end of the main bracket 203 is rotatably connected to the floating frame 5, and the other end is abutted against the back bed board 201 through a roller 209. When the main bracket 203 rotates relative to the floating frame 5, the roller 209 at the end can roll along the back bed board 201, thereby pushing the back bed board 201 to rotate relative to the lower body bed board 6, thereby achieving the action of lifting the user's back. One end of the side bracket 207 is connected to the main bracket 203, and the other end is abutted against the wedge block 210 of the back side board 202 through a pulley 208. When the main bracket 203 rotates, it can not only push the back bed board 201 to rotate through the roller 209, but also push the back side board 202 to rotate relative to the back bed board 201 through the side bracket 207 and the pulley 208. In particular, a wedge block 210 is provided on the back side plate 202 to cooperate with the pulley 208 at the end of the side bracket 207. The pulley 208 runs along the wedge block 210 on the moving path, which can increase the rotation range of the back side plate 202 relative to the back bed board 201. The driving member 211 is connected to the main bracket 203, and is used to drive the main bracket 203 and the side bracket 207 to rotate relative to the floating frame 5.

[0062] like Figure 3As shown, the wedge block 210 is used as a structure for guiding the movement of the pulley 208, so that when the back bed board 201 is rotated and lifted, the back side board 202 can rotate with a larger amplitude relative to the back bed board 201, thereby increasing the depth of the groove formed by the back bed board 201 and the back side board 202. The increase in the depth of the groove can provide better support and protection by using the back side board 202 during the user's back lifting process, reducing the risk of the user slipping off the bed. The entire design not only ensures the comfort and stability of the user during the back lifting process, but also provides sufficient flexibility to meet the needs of different users.

[0063] The connecting rod mechanism is a double rocker mechanism, and the floating frame 5 serves as the frame of the double rocker mechanism. The connecting rod of the double rocker mechanism is respectively hinged to the floating frame 5 and the back bed board 201, and the back bed board 201 serves as the connecting rod of the double rocker mechanism. The upper body bed board 6 can retreat relative to the lower body bed board 6 when rotating and lifting, thereby increasing the gap between the upper body bed board 6 and the lower body bed board 6.

[0064] In the process of raising the back of a traditional nursing bed, the change in the angle between the back bed board 201 and the lower body bed board 6 may cause pressure on the user's abdomen. In this embodiment, by using a double rocker mechanism as a connecting rod mechanism, the upper body bed board 6 can be moved back relative to the lower body bed board 6 when rotating and raising, thereby increasing the gap between the upper body bed board 6 and the lower body bed board 6, effectively reducing the pressure on the user's abdomen.

[0065] like Figure 2 As shown, the connecting rod includes a first connecting rod and a second connecting rod, and the double rocker mechanism is provided with two groups of symmetrically distributed to improve stability and balance. The first connecting rod and the second connecting rod corresponding to the two groups of double rocker mechanisms are respectively hinged to different positions of the floating frame 5 and the back bed board 201 to form a stable quadrilateral structure. One end of the first connecting rod and one end of the second connecting rod are respectively rotatably connected to different positions of the floating frame 5, and the other end of the first connecting rod and the other end of the second connecting rod are respectively rotatably connected to different positions of the back bed board 201.

[0066] like Figure 2 As shown, the first connecting rods corresponding to the two sets of double rocker mechanisms are located between the second connecting rods corresponding to the two sets of double rocker mechanisms, and a stabilizing rod is connected between the first connecting rods corresponding to the two sets of double rocker mechanisms to enhance the stability of the structure.

[0067] The main support 203 includes a rotating shaft 212, a back-lifting rod and a crank arm 215. The back-lifting rod and the crank arm 215 are respectively connected to the rotating shaft 212. Both ends of the rotating shaft 212 are rotatably installed on the floating frame 5. The end of the crank arm 215 away from the rotating shaft 212 is connected to the driving member 211, and receives the action of the driving member 211, so that the rotating shaft 212 can be adjusted to rotate relative to the floating frame 5, thereby adjusting the back-lifting rod connected to the rotating shaft 212 to swing. A roller 209 is installed at the end of the back-lifting rod away from the rotating shaft 212, and the swing of the back-lifting rod drives the roller 209 to push the back bed board 201 to rotate.

[0068] The driving member 211 is connected to the main support 203 and is used to drive the main support 203 to rotate relative to the floating frame 5. The driving member 211 can be a linear telescopic power device such as a telescopic electric cylinder or a hydraulic cylinder. The crank arm 215 and the back-lifting rod are respectively distributed radially along the rotating shaft 212. The driving member 211 is a telescopic rod 102. One end of the driving member 211 is hinged to the floating frame 5, and the other end is hinged to the crank arm 215. The telescopic action of the driving member 211 is converted into the rotation of the rotating shaft 212, which can realize the driving of the crank arm 215 and the main support 203, thereby completing the back-lifting action.

[0069] like Figure 2 As shown, the rotating shaft 212 is the core component of the main support 203. When the floating frame 5 is arranged horizontally, the axis of the rotating shaft 212 is also horizontally distributed. The rotating shaft 212 plays the role of connecting and supporting the back-lifting rod and the crank arm 215. The two ends of the rotating shaft 212 are respectively rotatably installed on the floating frame 5, so that the main support 203 can rotate relative to the floating frame 5. One end of the back-lifting rod is connected to the rotating shaft 212, and the other end is installed with a roller 209. The wedge block 210 is installed on the side of the back side plate 202 facing the floating frame 5. The back bed board 201 is provided with a guide rail for the roller 209 to abut. The shape and position design of the guide rail ensure that the roller 209 can smoothly drive the back bed board 201 to perform the back-lifting action during the rolling process. The roller 209 cooperates with the guide rail on the back bed board 201. When the main support 203 rotates, the roller 209 rolls on the guide rail, thereby driving the back bed board 201 to perform the back-lifting action.

[0070] like Figure 3 As shown, the crank arm 215 is connected to the rotating shaft 212, but is spaced apart from the back-lifting rod in the axial direction of the rotating shaft 212 and is located at different circumferential positions of the rotating shaft 212. One end of the crank arm 215 away from the rotating shaft 212 is connected to the driving member 211, and the rotation of the crank arm 215 and the entire main bracket 203 is driven by the telescopic movement of the driving member 211.

[0071] The side bracket 207 is connected to the main bracket 203 and has a cantilever structure. A pulley 208 is installed at the end of the side bracket 207. The function of the pulley 208 is to cooperate with the wedge block 210 on the back side panel 202. When the main bracket 203 rotates, the pulley 208 slides on the wedge block 210, thereby pushing the back side panel 202 to rotate, forming a side protection for the user. The wedge block 210 is installed on the side of the back side panel 202 facing the floating frame 5. Its shape design allows the pulley 208 to generate a certain thrust when it slides on it, pushing the back side panel 202 to rotate.

[0072] like Figure 2 As shown, by designing the wedge block 210 and the connecting rod mechanism, a smooth, comfortable and stable back-lifting process is achieved, which can enhance the user experience and make the user feel more at ease and comfortable when receiving care. By optimizing the back-lifting process, the user can be more relaxed when receiving care, which is beneficial to the user's rehabilitation and recovery.

[0073] By designing the cooperation between the roller 209 and the guide rail, and the telescopic rod 102 driving the crank 215, the back-lifting action is smooth and controllable, which helps to reduce the impact and discomfort on the user's body during the back-lifting process. By designing the cooperation between the side bracket 207 and the wedge block 210, when the main bracket 203 rotates, the side bracket 207 can automatically push the back side plate 202 to rotate, forming a side protection for the user, increasing the safety of the nursing bed and the user's experience.

[0074] Traditional nursing beds lack side protection during the back-lifting process, and users are prone to slipping off the two sides of the back bed board 201, causing accidents. In this embodiment, by designing the back-lifting assembly and the back side panels 202, the back side panels 202 can automatically rotate inward and lift up to form a protective structure during the back-lifting process, effectively preventing the user from slipping off.

[0075] Combination Figure 2 and Figure 3 , the overall working process of the lifting system 2: The overall working process of the back-lifting system 2 is mainly centered around its back-lifting function. When the user lying on the back needs to be assisted to lift up, the driving member 211 (such as an electric push rod) in the back-lifting assembly is activated to drive the main support 203 to rotate relative to the floating frame 5. One end of the main support 203 is rotatably connected to the floating frame 5, and the other end is abutted against the back bed board 201 through the roller 209. As the main support 203 rotates, the roller 209 rolls on the back bed board 201, thereby pushing the back bed board 201 to rotate and lift relative to the lower body bed board 6.

[0076] At the same time, the side bracket 207 connected to the main bracket 203 also moves accordingly. One end of the side bracket 207 is connected to the main bracket 203, and the other end is abutted against the wedge block 210 of the back side board 202 through the pulley 208. As the main bracket 203 rotates, the pulley 208 of the side bracket 207 moves on the wedge block 210. This movement process not only ensures that the side bracket 207 can move along the predetermined path of the back side board 202, but also through the abutment and push of the pulley 208, the back side board 202 is rotated and lifted inward relative to the back bed board 201. In the process of rotating and lifting the back bed board 201, the back side board 202 also forms a protective structure synchronously, which effectively prevents the user from sliding off the side of the back bed board 201 during the back-raising process or in the sitting state.

[0077] In addition, the nursing bed also uses a double rocker mechanism to connect the floating frame 5 and the back bed board 201, so that the upper body bed board 6 can retreat relative to the lower body bed board 6 when rotating and lifting, thereby increasing the gap between the upper body bed board 6 and the lower body bed board 6. Not only does it achieve decompression of the user's abdomen during the back lifting process, but it also improves the user's comfort and safety.

[0078] In the prior art, a nursing bed with a function of cleaning the toilet bowl 301 after defecation can solve the cleaning problem of the user, and can automatically flush the inner wall of the toilet bowl 301 and the user's defecation area, but the matching position of the nozzle and the toilet bowl 301 has an uneven structure, which is easy to hide dirt, and the nozzle body is blocked, resulting in incomplete cleaning. When cleaning the toilet bowl 301, the toilet bowl cover 306 is easily contaminated by splashing, increasing the risk of cross infection.

[0079] Based on this, Figure 6-Figure 8 As shown, the flushing system 3 of this embodiment includes a human body flushing component and a cover flushing component 302 installed on the bedpan 301, and the output ends thereof can be respectively extended and retracted relative to the bedpan 301 to reach into the bedpan 301 or be pulled out of the bedpan 301 to clean the body of the patient on the bedpan 301 and the bedpan cover 306 of the bedpan 301. A basin flushing component 307 is installed on the side of the bedpan cover 306 away from the contact with the human body. After the bedpan cover 306 is closed to block the top opening of the bedpan 301, the basin flushing component 307 is used to flush the bedpan 301, thereby reducing splashing when flushing the bedpan 301 and reducing residual dirt.

[0080] like Figure 8As shown, the flushing system 3 mainly includes a toilet bowl 301, a toilet bowl cover 306, a body flushing assembly 303, a cover flushing assembly 302 and a basin flushing assembly 307. The toilet bowl 301 is provided with a cavity 304 with a top opening, and the toilet bowl 301 is rotatably connected to the toilet bowl cover 306. The toilet bowl cover 306 can adjust its position by flipping. When the toilet bowl cover 306 flips to the bottom of the opening of the cavity 304, it can penetrate into the cavity 304, and the upper opening can be used for the user to defecate. When the toilet bowl cover 306 flips in the opposite direction and rotates to the opening position of the cavity 304, it can block the opening of the cavity 304. The body flushing assembly 303 includes a first telescopic member and a first nozzle 309 installed at the output end of the first telescopic member, which can penetrate into the cavity 304 through the side wall of the toilet bowl 301, spray water to clean the human body at the capacity opening, and can also retract outside the toilet bowl 301 through the side wall of the toilet bowl 301 for storage, thereby reducing the attachment of dirt when other flushing components are working. The lid flushing assembly 302 includes a second telescopic member and a second nozzle 311 installed at the output end of the second telescopic member. The second nozzle 311 faces the toilet lid 306 inserted into the cavity 304 and can penetrate through the side wall of the toilet 301 into the cavity 304 or retract outside the toilet 301. When the second nozzle 311 is in the cavity 304, it can spray water to clean the toilet lid 306. The toilet flushing assembly 307 is provided with a third nozzle 313, which is installed on the side of the toilet lid 306 away from the human body, and is used to flush the toilet 301 when the toilet lid 306 is closed to reduce splashing during flushing.

[0081] Through the telescopic parts of the body flushing component 303 and the cover flushing component 302, the user's body and the toilet cover 306 in the toilet bowl 301 are fully cleaned, avoiding the problem of dirt and grime hidden due to the uneven matching position of the nozzle and the toilet bowl 301. By installing the toilet bowl flushing component 307 on the side of the toilet bowl cover 306 away from the contact with the human body, flushing is performed after the toilet bowl cover 306 is used to block the top opening of the toilet bowl 301, which effectively reduces the splashing when flushing the toilet bowl 301, and reduces the risk of residual dirt and cross infection. The cleaning efficiency and cleaning quality are improved, ensuring the health and safety of users and caregivers. The splashing and residual dirt during the flushing process are reduced, and the risk of cross infection is reduced. It has a wide range of applications and is suitable for the treatment and cleaning of various dirt.

[0082] like Figure 8As shown, the basin flushing assembly 307 is provided with a third nozzle 313, which is installed on the side of the toilet cover 306 away from the human body, and can follow the toilet cover 306 to flip to the top of the cavity 304, and the first nozzle 309, the second nozzle 311 and the third nozzle 313 are respectively connected to the pressure water source. The first nozzle 309 is used to spray and clean the user's body after defecation. The second nozzle 311 is used to spray and clean the toilet cover 306 after the human body is cleaned. The third nozzle 313 is used to flush and clean the first nozzle 309, the second nozzle 311 and the toilet 301 cavity 304 to ensure the cleanliness of the entire system.

[0083] During use, since the bedpan cover 306 can be triggered to open by the patient's initial defecation, dirt is also attached to the bedpan cover 306 body, and after the bedpan cover 306 is opened, dirt is easily splashed and attached to the bedpan cover 306 during the patient's defecation process. In this regard, in this embodiment, a cover flushing component 302 is configured to cooperate with the bedpan 301, which can be extended into the bedpan 301 when in use to flush and clean the bedpan cover 306. Since the output end of the cover flushing component 302 is higher than the height of the bedpan cover 306 when it is in the open state, the bedpan cover 306 can be cleaned at an oblique downward spray angle.

[0084] like Figure 7 As shown, the lid flushing assembly 302 is arranged on the side of the toilet bowl 301. After the toilet bowl lid 306 is opened, it can be output toward the toilet bowl lid 306 for flushing. At this time, the toilet bowl lid 306 is located inside the toilet bowl 301, which can achieve accurate and comprehensive flushing and reduce the overflow of flushing water. The toilet bowl lid 306 in a drooping state can achieve gravity drainage for easy drying. It is understandable that the surface of the toilet bowl lid 306 can be made of a hydrophobic layer for easy flushing and cleaning.

[0085] like Figure 8 As shown, the toilet bowl 301 serves as the main structure, and two openings are provided on the side wall of the toilet bowl 301, namely a first opening 315 for the first nozzle 309 to pass through and a second opening 314 for the second nozzle 311 to pass through. The two openings enable the nozzles to directly clean the inside of the toilet bowl 301.

[0086] The first stopper 310 cooperates with the first opening 315, and the second stopper 312 cooperates with the second opening 314, to block the two openings when the nozzle is not in use, to prevent water or other substances from overflowing from the openings. The stopper is connected to the toilet bowl 301 by rotation, and a reset spring is provided at the connection position to ensure that the stopper can automatically return to the position of blocking the opening when no force is applied. The reset spring can be a torsion spring. When the telescopic member drives the nozzle to push the stopper, the stopper can be opened to allow the nozzle to probe into the cavity 304 for operation.

[0087] like Figure 6 As shown, the bedpan cover 306 is used to cover the opening portion of the bedpan 301 to provide privacy and sanitation protection. The bedpan cover 306 is connected to the bedpan 301 through a cover bracket 308, and one end of the cover bracket 308 is rotatably mounted on the bedpan 301, so that the bedpan cover 306 can be easily opened and closed.

[0088] Specifically, when not in use, the toilet cover 306 is usually in a closed position, that is, covering the opening of the toilet 301. At this time, the cover bracket 308 serves as a bridge connecting the toilet 301 and the toilet cover 306, and its end away from the toilet cover 306 is installed on the side wall of the toilet 301 using a rotating member (such as a hinge, a rotating shaft 212, etc.). The cover bracket 308 can also be equipped with a rotating driving member 211, such as an electric motor, a servo motor, a rotary cylinder, etc., to drive the cover bracket 308 to rotate and drive the toilet cover 306 to rotate and adjust the position.

[0089] like Figure 6 and Figure 8 As shown, when the user needs to open the toilet lid 306, the lid bracket 308 is driven by the rotating driving member 211, so that the lid bracket 308 can rotate around its rotation axis. As the lid bracket 308 rotates, the toilet lid 306 gradually falls from the opening of the toilet 301 until it reaches a fully opened state. The process of closing the toilet lid 306 is the opposite of the opening process. The lid bracket 308 is turned by the rotating driving member 211, so that the toilet lid 306 gradually rises along the trajectory of the lid bracket 308, so that the toilet lid is smoothly buckled on the opening of the toilet 301 from the bottom, and a tight closure is achieved.

[0090] The first nozzle 309, the second nozzle 311 and the third nozzle 313 are all provided with a plurality of nozzles and are connected to a pressure water source respectively. These nozzles clean the toilet bowl 301 and its surroundings by spraying water. In particular, the second nozzle 311 is located obliquely above the toilet bowl cover 306 that extends into the cavity 304, and its spraying area covers the side of the toilet bowl cover 306 that contacts the human body, ensuring that the toilet bowl cover 306 is fully cleaned.

[0091] After the toilet cover 306 blocks the opening at the top of the toilet chamber 304, the third nozzle 313 is a rotating nozzle suspended at the top of the chamber 304, and the third nozzle 313 has a wider spraying range or a more flexible cleaning method. The toilet cover 306 is provided with a hydrophobic layer, which helps to reduce the retention of water on the toilet cover 306, improve the drainage efficiency, reduce the residue of clean water on the toilet cover 306, keep it dry and improve the comfort.

[0092] By installing the basin flushing assembly 307 on the side of the toilet cover 306 that is away from the human body, and using the toilet cover 306 to block the top opening of the toilet 301 during flushing, the splashing when flushing the toilet 301 is effectively reduced. The design of the first opening 315 and the second opening 314, as well as the matching cover, further reduce the risk of dirt residue and cross infection caused by the flushing process. The cleaning problem of the toilet 301 and its surrounding area is solved. By introducing multiple nozzles, especially the second nozzle 311 for cleaning the toilet cover 306, and the rotation cleaning method of the third nozzle 313, the toilet 301 and its surrounding area are fully and efficiently cleaned. At the same time, the design of the cover prevents the overflow of water or other substances when the nozzle is not in use, thereby improving the safety and convenience of use.

[0093] like Figure 6 As shown, a telescopic spray rod can be used for the first telescopic part and the second telescopic part. The spray rod adopts a telescopic design, is driven by a stepper motor, supports multi-stage telescoping, and can adjust the length and angle of the spray rod according to the user's body shape and defecation situation to ensure the cleaning effect; the nozzle of the first nozzle 309 is designed to cover a circular area of ​​170mm diameter on the buttocks, and has a fixed-point flushing function for the buttocks and anus. The water outlet pressure and flow rate of the first nozzle 309 can be adjusted by the control system to meet the needs of different users.

[0094] In addition, the spray rod is equipped with an automatic self-cleaning function, which can automatically clean the spray rod and nozzle after each use to avoid cross infection. This function complies with the requirements of the GB / T 34549-2024 "Smart Toilet" standard to ensure the hygiene of the system. In order to meet the needs of female users, the body flushing component 303 also has a feminine wash function. The first nozzle 309 can be extended to the appropriate position for cleaning under the drive of the spray rod, and automatically recovered after the cleaning is completed. The extension and recovery time are controlled within seconds and seconds respectively to ensure the cleaning effect and safety.

[0095] In other optional embodiments, the first telescopic member and the second telescopic member both adopt a multi-stage telescopic design, that is, they include one or more telescopic sleeves, which can be nested in each other and perform telescopic movement under the action of external force. The connection between the sleeves may be threaded, snap-on or sliding, etc., to ensure stability and reliability during the telescopic process. The telescopic movement is usually powered by a drive device such as a motor, a cylinder or a hydraulic cylinder. The drive device transmits power to the telescopic sleeve through a transmission mechanism such as a gear, a chain, or a belt, thereby realizing the telescopic movement. The movement of the telescopic member is usually controlled by one or more sensors and a controller. The sensor is used to detect parameters such as the position and speed of the sleeve, and feed this information back to the controller. The controller accurately controls the drive device according to a preset algorithm and logic to achieve accurate control of the telescopic movement.

[0096] like Figure 8 As shown, the third nozzle 313 adopts a water flow self-driven rotating nozzle, that is, the kinetic energy generated when the water flows through the nozzle is used to drive the rotation of the rotating part. When the water flows into the nozzle body, it will impact the blades or turbine structure inside the rotating part, thereby generating a rotational torque. The rotating part begins to rotate under the action of the rotational torque, and drives the water outlet to rotate together. Since the direction of the water outlet changes with the rotation of the rotating part, the spraying range will also be expanded accordingly. In order to achieve precise control of the spraying range and spraying pattern, the third nozzle 313 can also be equipped with an adjustment device. The adjustment device can adjust parameters such as the speed, pressure and direction of the water flow, thereby achieving precise adjustment of the spraying effect.

[0097] Combination Figure 6-Figure 8 , the working method of the flushing system 3 includes: When the user is not defecating, the toilet bowl cover 306 blocks the top opening of the chamber 304 and contacts the human body for auxiliary support; When the user defecates, the toilet lid 306 flips over to open the opening at the top of the chamber 304, so that feces passes through the opening and falls into the chamber 304; After defecation, the first nozzle 309 of the body washing component 303 reaches into the toilet bowl 301 to spray and clean the user's body. After the body is cleaned, the toilet bowl cover 306 is sprayed and cleaned through the second nozzle 311. The toilet bowl cover 306 is turned over after cleaning and draining to block the top opening of the cavity 304. The third nozzle 313 operates to flush and clean the first nozzle 309, the second nozzle 311 and the chamber 304 of the toilet bowl 301. After cleaning, the first nozzle 309 and the second nozzle 311 retract outside the toilet bowl 301 to wait for the user to defecate next time.

[0098] After defecation is completed and the chamber 304 of the toilet bowl 301 is flushed and cleaned, the dirt in the toilet bowl cover 306 is discharged by flushing.

[0099] Specifically, flushing and cleaning are basic means to maintain a sanitary environment. In the use scenario of a two-defecation nursing bed, since it involves the treatment of human excrement, the flushing and cleaning steps are particularly important. Multiple flushing and cleaning can ensure that the dirt is completely removed and reduce the possibility of residue and bacterial growth. Through multiple flushing and cleaning, dirt, residues and bacteria in the system can be removed, thereby keeping the system clean and sanitary. A clean environment helps reduce the spread of bacteria and viruses, thereby reducing the risk of cross-infection. A clean and sanitary environment is the basis for protecting the health of users and can reduce diseases and discomfort caused by hygiene problems.

[0100] In the working method of the flushing system 3, the actual operation process includes the following steps: Preliminary flushing after defecation: After the user has a bowel movement, a preliminary flushing is first performed to discharge most of the feces and dirt in the cavity 304.

[0101] Body flushing component 303 cleaning: After the initial flushing, the first nozzle 309 of the body flushing component 303 reaches into the toilet bowl 301 to spray and clean the user's body, aiming to remove residues and bacteria on the human body and ensure the cleanliness and comfort of the user.

[0102] Cleaning of the toilet lid 306: After the human body is cleaned, the second nozzle 311 sprays and cleans the toilet lid 306. The toilet lid 306 may have dirt or bacteria left after contacting the human body, so it needs to be cleaned.

[0103] Deep cleaning of the toilet bowl 301 cavity 304: After the toilet bowl cover 306 is cleaned, the third nozzle 313 works to deeply rinse and clean the first nozzle 309, the second nozzle 311 and the toilet bowl 301 cavity 304. This step is intended to remove all residues and bacteria to ensure the cleanliness of the entire system.

[0104] Dirt discharge in the toilet bowl cover 306: After all flushing and cleaning steps are completed, the dirt in the toilet bowl cover 306 is discharged by flushing. The cleanliness of the interior of the toilet bowl cover 306 is ensured, and the possibility of bacterial growth is reduced.

[0105] Through multiple flushing and cleaning steps, the entire two-defecation nursing bed system can maintain a high degree of cleanliness and hygiene. This not only reduces the risk of cross infection, but also protects the health of users. At the same time, the clean environment also helps to improve the comfort and satisfaction of users, thereby enhancing the overall user experience.

[0106] The current nursing bed with an automatic bedpan 301 system, although the automatic opening of the bedpan cover 306 and the automatic falling of excrement into the bedpan 301 are realized, there are problems in cleaning the bedpan 301. The water spray element embedded in the bedpan 301 is easy to form a cleaning dead angle at the installation position, and the cleaning effect of these positions is poor, affecting the sanitation and safety of the bedpan 301. In order to reduce the cleaning dead angle, it is necessary to increase the cleaning range of a single water spray element, but this usually requires increasing the water pressure, and increasing the water pressure is easy to cause splashing and overflowing problems, further affecting the sanitation and safety of the nursing bed.

[0107] like Fig. 9 and Fig.10As shown, in this embodiment, the toilet bowl cover 306 is designed in detail, and the bowl flushing component 307 also includes a fourth nozzle 3063. The third nozzle 313 and the fourth nozzle 3063 for cleaning the toilet bowl 301 are integrated and installed on the cover body 3062 of the toilet bowl cover 306, thereby reducing the number of nozzles set inside the toilet bowl 301, thereby reducing the cleaning dead corners on the inner wall of the toilet bowl 301. The fourth nozzle 3063 and the third nozzle 313 that move with the cover body 3062 can adjust their directions and work within the range of the toilet bowl 301, thereby solving the problems of cleaning dead corners and splashing and overflowing, and improving the cleaning effect and hygienic safety of the toilet bowl 301.

[0108] like Fig.10 As shown, the bedpan cover 306 mainly includes a cover body 3062, a cover bracket 308 and a defecation identification element 3061. The cover body 3062 is used in combination with the bedpan 301 of the two-defecation nursing bed. The cover body 3062 can block the opening of the bedpan 301, and can also leave the opening position of the bedpan 301 to open the opening of the bedpan 301. When the cover body 3062 blocks the opening of the bedpan 301, it can contact the user's body and carry the user's body part. The cover bracket 308 is connected to the cover body 3062, and the cover body 3062 is installed at the position of the bedpan 301 of the two-defecation nursing bed through the cover bracket 308. The cover bracket 308 drives the cover body 3062 to complete the required rotation and flipping actions to achieve blocking or opening the opening of the bedpan 301.

[0109] Combination Fig.10 and Figure 8 The cover body 3062 is rotatably mounted on the external toilet bowl 301 through the cover bracket 308, and the direction can be adjusted as the cover bracket 308 rotates. One side of the cover body 3062 is a detection surface for detecting the presence of excrement. A feces storage tank is provided on the detection surface for temporarily storing excrement. The feces storage tank is also connected to a urinary catheterization tank, which can guide excrement outside the range of the feces storage tank into the feces storage tank. A feces identification element 3061 is also installed in the feces storage tank for identifying the type of excrement. In addition to installing the third nozzle 313 on the side of the cover body 3062 away from the user's body, a plurality of fourth nozzles 3063 are distributed around the detection surface on the circumferential side of the cover body 3062, and the fourth nozzle 3063 can adjust the direction as the cover body 3062 is rotated by the cover bracket 308. A water supply pipeline is embedded inside the cover body 3062, and the fourth nozzle 3063 is connected to the water supply pipeline, which is in turn connected to an external pressure water source. The external pressure water source supplies water to the water supply pipeline, so that the water passes through the water supply pipeline and is discharged through the fourth nozzle 3063 to form a water jet to flush and clean the action position.

[0110] like Fig. 9As shown, by distributing the fourth nozzle 3063 on the circumferential side of the cover body 3062, the toilet cover 306 and the toilet bowl 301 can be cleaned in all directions, avoiding the problem of cleaning dead corners. The fourth nozzle 3063 adjusts its direction as the cover bracket 308 and the cover body 3062 rotate, which can ensure the uniformity and comprehensiveness of cleaning. Since the fourth nozzle 3063 is distributed on the circumferential side of the cover body 3062, instead of all the water spraying elements being concentrated inside the toilet bowl 301, the number of water spraying elements arranged inside the toilet bowl 301 is reduced, and the requirement of covering the cleaning range inside the toilet bowl 301 can be met. At the same time, the risk of splashing and overflowing can be further reduced by accurately controlling the water spraying amount and water spraying time of the fourth nozzle 3063.

[0111] By cleaning in all directions and avoiding cleaning dead corners, the bedpan cover 306 can significantly improve the cleaning effect of the bedpan 301 and maintain the hygiene and safety of the bedpan 301. Through the reasonable layout of the fourth nozzle 3063, the fourth nozzle 3063 on the cover body 3062 can clean the inner wall of the bedpan 301 in the bedpan 301, reduce the distance from the fourth nozzle 3063 to the target cleaning position, reduce pressure loss, and improve the water jet cleaning effect. After the cover body 3062 cooperates with the opening of the bedpan 301 to seal, it can also isolate the inside of the bedpan 301 from the outside world, so that when cleaning the inside of the bedpan 301, the problem of splashing and overflow can be effectively reduced, and the hygiene and safety of the two-defecation nursing bed can be further guaranteed.

[0112] The improvement of cleaning effect and the reduction of splashing and overflow can significantly improve the user experience and make the defecation and urination care bed more comfortable, convenient and safe.

[0113] The feces storage tank is the main collection area for feces before the cover 3062 is opened, and the feces storage tank is located near the center of the cover 3062. Among them, the cover 3062 is a gourd-shaped plate structure with a narrow front end and a wide rear end. It is manufactured using PU foam molding technology and has embedded antibacterial components to effectively inhibit bacterial growth and ensure hygiene and safety. It is not only easy to clean, but also improves the strength and durability of the bedpan cover 306. The gourd-shaped cover 3062 has a relatively smooth curved surface, which reduces the hiding space for dirt and bacteria, making cleaning more convenient, keeping the equipment clean and hygienic, preventing cross infection, and ensuring the health of the user. In addition, the cover 3062 can better fit the curve of the human body, effectively disperse pressure, reduce the sense of pressure on the user's body, and reduce discomfort.

[0114] The urinary catheter is connected to the fecal storage tank and is distributed on both sides of the fecal storage tank. The urinary catheter is distributed obliquely. From the end of the cover 3062 to the fecal storage tank, the depth of the urinary catheter relative to the detection surface gradually increases. The inclined urinary catheter is used to guide the urine to flow to the fecal storage tank to prevent the urine from spreading everywhere. The two sides of the fecal storage tank are connected with urinary catheters, which extend to the end of the cover 3062. The urinary catheter and the fecal storage tank are distributed on the connecting line at both ends of the cover 3062 to ensure that the excrement can fall smoothly into the fecal storage tank, so as to be easily identified by the defecation identification element 3061, thereby triggering the action of opening the cover 3062.

[0115] like Fig. 9 As shown, in the direction perpendicular to the line connecting the two ends of the cover body 3062, the width of the feces storage tank is greater than the width of the urinary catheterization tank, and the feces storage tank is smoothly connected to the urinary catheterization tank, so that the feces storage tank has a basic containing function and reduces the overflow of excrement.

[0116] The defecation identification element 3061 includes a temperature sensor and a humidity sensor for detecting defecation activities. The temperature sensor and the humidity sensor are installed in the feces storage tank, and the humidity sensor is installed in the urine catheter tank, which can identify urine more quickly.

[0117] The defecation identification element 3061 is installed on the cover 3062 and placed near the excretion organ, and the detection range is set (such as ℃ to ℃). When the excrement (especially feces) is discharged, its temperature is different from the temperature of the surrounding environment. The temperature sensor can capture this temperature change, which is used as a basis for identifying the defecation activity. The humidity sensor is used to detect the moisture content in the excrement. Since there is a significant difference in humidity between feces and urine, the humidity sensor can be used to distinguish between feces and urine. For feces, the humidity is relatively low, but still higher than the surrounding environment. When feces are discharged, the humidity sensor can detect the change in humidity. For urine, the humidity is higher and is usually in liquid form. Therefore, the humidity sensor installed in the urinary catheter can identify the discharge of urine more quickly. Specifically, a temperature sensor and a humidity sensor are installed in the fecal storage tank and the urinary catheter respectively. The temperature sensor and humidity sensor in the fecal storage tank are used to detect the discharge of feces, while the humidity sensor in the urinary catheter is specifically used to detect urine.

[0118] When the defecation identification element 3061 detects excrement, it generates corresponding electrical signals, which are collected and transmitted to the processing unit (such as a microcontroller) for further processing. The processing unit analyzes and judges based on the received signals (such as temperature, humidity, etc.) to determine whether defecation activity has occurred, and further distinguishes whether it is defecation or urination. Once the processing unit determines that defecation activity has occurred and identifies whether it is defecation or urination, the system will trigger the corresponding alarm or feedback mechanism. For example, the cover 3062 is opened so that the excrement on the cover 3062 and the user's subsequent excretion can enter the toilet bowl 301; for incontinent users or the elderly, the system can automatically send an alarm message to the caregiver to prompt them to clean and care.

[0119] like Figure 7 and Fig.10 As shown, one end of the cover bracket 308 is connected to the side of the cover body 3062 away from the detection surface, and the other end extends to the outside of the cover body 3062, connected to the toilet bowl 301, and is configured with a corresponding driving element. The driving element drives the cover body 3062 to rotate and adjust the position through the cover bracket 308. The driving element can be a servo, an electric motor, a rotary cylinder, etc.

[0120] The fourth nozzle 3063 is installed on the circumferential side of the cover 3062 for spraying water for cleaning. A plurality of fourth nozzles 3063 are installed on the circumferential side of the cover 3062, and adjacent fourth nozzles 3063 are spaced apart. The output ends of the fourth nozzles 3063 face away from the cover 3062. The fourth nozzles 3063 are divided into multiple groups, and each group is connected to the same water supply pipeline through a control valve. By accurately controlling the spraying amount and spraying time of the fourth nozzle 3063, the risk of splashing and overflowing can be further reduced, and the use hygiene of the two-defecation nursing bed can be maintained.

[0121] By dividing the plurality of fourth nozzles 3063 into a plurality of groups and connecting them to the same water supply pipeline through control valves, more flexible water spray control can be achieved. In the actual cleaning process, some groups of fourth nozzles 3063 can be selectively opened or closed as needed, so as to more accurately cover the area to be cleaned. This group control method avoids the problem of waste of resources and poor cleaning effect caused by opening all fourth nozzles 3063 at the same time, and improves the cleaning efficiency.

[0122] Specifically, in order to achieve accurate control of the water spraying amount and water spraying time of the fourth nozzle 3063, an intelligent control system is adopted, and an intelligent control system such as a PLC (programmable logic controller) or a single chip microcomputer is introduced to accurately control the fourth nozzle 3063. Through programming setting, the water spraying amount, water spraying time and water spraying interval of each fourth nozzle 3063 or each group of fourth nozzles 3063 can be accurately adjusted.

[0123] A flow sensor may also be installed on the water supply pipeline to monitor the flow of water in real time to ensure that the water spray volume of the fourth nozzle 3063 meets the preset requirements. A pressure sensor 3055 may be installed to monitor the water supply pressure to avoid unstable water spraying caused by pressure fluctuations.

[0124] According to actual needs, the shape, size and water outlet design of the fourth nozzle 3063 are optimized to reduce the risk of splashing and overflowing. For example, a fan-shaped or conical water outlet can be used to make the water flow more evenly and gently sprayed. A variety of water spray modes are set in the intelligent control system, such as gentle mode, strong mode, etc., to meet the cleaning needs in different scenarios. According to actual needs, the most suitable water spray mode is selected to reduce the risk of splashing and overflowing. The group configuration control method also helps to enhance the cleaning effect. In actual applications, different fourth nozzle 3063 combinations and water spray modes can be selected according to different cleaning needs. For example, for stubborn stains or difficult-to-clean areas, a fourth nozzle 3063 combination with a larger water spray intensity can be selected for key cleaning; and for some more sensitive or easily damaged areas, a fourth nozzle 3063 combination with a smaller water spray intensity can be selected for gentle cleaning. The flexible control method makes the cleaning process more flexible and diverse, and can better meet the cleaning needs in different scenarios.

[0125] like Fig. 9 As shown, the water supply pipeline is a channel distributed inside the cover body 3062, which can maximize the use of the space inside the cover body 3062. It avoids the space occupation problem caused by the external placement of the traditional water supply pipeline, making the entire device more compact and small, and suitable for installation in the toilet 301 with limited space. The water supply pipeline is built into the cover body 3062, which can simplify the installation and maintenance process. During installation, there is no need to worry about the layout and connection of the pipeline, just install the cover body 3062 in the designated position. The water supply pipeline is not easily disturbed or damaged by the external environment, which improves the durability and service life of the equipment. At the same time, since the water supply pipeline is integrated with the cover body 3062 structure, it can also reduce the leakage problem caused by loose or damaged pipelines.

[0126] Combination Fig. 9 and Fig.10 , the working method of the bedpan cover 306 includes: The cover body 3062 is installed on the bedpan 301 of the two-toilet nursing bed through the cover bracket 308. The cover bracket 308 rotates to drive the cover body 3062 to flip and block the opening of the bedpan 301. The cover bracket 308 rotates in the opposite direction to drive the cover body 3062 to rotate to the side of the bedpan 301 below the opening of the bedpan 301. When the cover 3062 blocks the opening of the toilet bowl 301, it can support the user. When the defecation identification element 3061 identifies urination or defecation, the cover bracket 308 drives the cover 3062 to flip so that the opening of the toilet bowl 301 is opened; After use, water is delivered into the water supply pipeline, and water is sprayed on the inner wall of the toilet bowl 301 through the fourth nozzle 3063 to clean the inner wall of the toilet bowl 301; After the cover body 3062 and the toilet bowl 301 are cleaned, the cover bracket 308 rotates to drive the cover body 3062 to flip and block the opening of the toilet bowl 301, waiting for the next defecation to be identified.

[0127] When the fourth nozzle 3063 sprays water to clean the inner wall of the toilet bowl 301, the cover bracket 308 drives the cover body 3062 to rotate and adjust the angle, and repeatedly swings to clean the inner wall of the toilet bowl 301.

[0128] Through the design of the cover bracket 308 and the cover body 3062, the opening of the toilet bowl 301 is automatically blocked and opened, which improves the convenience and hygiene of use. The introduction of the defecation recognition element 3061 can automatically identify urination or defecation and trigger corresponding actions, such as the flipping of the cover body 3062, which improves the intelligence level of the device. Through the design of the water supply pipeline and the fourth nozzle 3063, the inner wall of the toilet bowl 301 is sprayed with water for cleaning, which reduces the trouble of manual cleaning and health hazards.

[0129] Specifically, the working method of the bedpan cover 306 is described in detail: Initial state: the cover 3062 is firmly mounted on the bedpan 301 of the two-defecation nursing bed through the cover bracket 308, and is in a state of blocking the opening of the bedpan 301. At this time, the cover 3062 can support the user to ensure his stability and safety on the bedpan 301.

[0130] Defecation identification: When the user defecates, the defecation identification element 3061 (such as a temperature sensor and a humidity sensor) will immediately detect the defecation activity. It can accurately identify whether it is defecation or urination, thereby providing an accurate signal for subsequent cleaning actions.

[0131] The cover 3062 flips and the opening of the toilet bowl 301 is opened: Once the defecation identification element 3061 sends a signal, the cover bracket 308 will immediately start and drive the cover 3062 to flip. This action is quick and smooth, ensuring that the user will not experience any interference or discomfort. With the flipping of the cover 3062, the opening of the toilet bowl 301 is completely opened, facilitating the discharge of excrement.

[0132] Excrement and collection: When the opening of the toilet bowl 301 is open, the user's excrement will be smoothly discharged into the toilet bowl 301. The toilet bowl 301 is designed with a reasonable collection structure to ensure that the excrement will not splash or leak.

[0133] Water spray cleaning: After use, the system will supply water to the water supply pipeline. The water is sprayed out through the fourth nozzle 3063 at a proper pressure and angle to cover the entire inner wall of the toilet bowl 301. The residues and stains on the inner wall of the toilet bowl 301 can be completely removed to ensure the hygiene and cleanliness of the toilet bowl 301.

[0134] Angle adjustment of the cover 3062 and repeated cleaning: During the water spray cleaning process, the cover bracket 308 will drive the cover 3062 to adjust its angle. This action enables the fourth nozzle 3063 to more fully cover the inner wall of the toilet bowl 301, ensuring that every corner can be thoroughly cleaned. By repeatedly swinging the cover 3062 and the fourth nozzle 3063, the inner wall of the toilet bowl 301 can be cleaned in all directions.

[0135] The cover 3062 is reset and waits for the next defecation: After cleaning, the cover bracket 308 will drive the cover 3062 to flip back to the initial position again to block the opening of the toilet bowl 301. At this time, the whole system is in a standby state, waiting for the signal of the next defecation recognition.

[0136] The current nursing bed for both defecation and urination can flush and clean the human body and the toilet bowl 301, but only considers the problem of flushing and cleaning, but does not deal with the problem of water leakage that may occur during the flushing process. This may cause water to leak out during flushing, wet the mattress around the toilet bowl 301, cause pollution, and further affect the hygienic use of the nursing bed.

[0137] In this regard, in this embodiment, a toilet seat 305 is installed on the toilet bowl 301. Fig.11 and Fig.12 As shown, the problem of water leakage during flushing and cleaning is solved, while the comfort of users is improved.

[0138] like Fig.11 As shown, the toilet seat 305 mainly includes a toilet seat body 3051, an airbag 3052 and a pressure sensor 3055. The toilet seat body 3051 is a main bearing structure, which can cooperate with the toilet bowl 301 on the two-container nursing bed, and is buckled on the top opening of the toilet bowl 301. The toilet bowl 301 body is provided with a toilet hole 3053 for the user to excrete, so that the excrement passes through the toilet hole 3053 and falls into the toilet bowl 301. The toilet hole 3053 is a through hole structure, and the airbag 3052 is arranged at the edge of the opening facing the human body, so that the airbag 3052 is distributed in a strip shape, and the opening of the toilet hole 3053 away from the human body faces the toilet bowl 301.

[0139] like Fig.12As shown, the airbag 3052 is divided into a fixed area and a contact area 3054. The fixed area is connected to the toilet seat body 3051 along the edge of the opening at one end of the toilet seat 305, and plays the role of fixing the airbag 3052. The contact area 3054 is distributed relative to the fixed area. When the air pressure in the airbag 3052 is adjusted, the airbag 3052 can be expanded or contracted. When the air pressure in the airbag 3052 is maintained, the shape of the airbag 3052 is also maintained. When the airbag 3052 is expanded, the fixed area keeps the airbag 3052 connected to the toilet seat body 3051, so that the contact area 3054 is far away from the fixed area. The contact area 3054 can protrude from the surface of the toilet seat body 3051, forming a structure that fits the human body or fits the fixed area. When the airbag 3052 shrinks, the contact area 3054 gradually approaches the fixed area until it fits the fixed area, and the whole is flush with the surface of the toilet seat body 301.

[0140] By adjusting the air pressure in the airbag 3052, the distance between the contact area 3054 and the fixed area can be changed, so that the contact area 3054 can remain close to the human body or be stored in the fixed area. When the airbag 3052 is inflated, the contact area 3054 fits the human body, forming a limiting area to block the flow of water, preventing water from flowing along the body to outside the opening range of the toilet bowl 301. When the pressure of the airbag 3052 is reduced to shrink the airbag 3052, the contact area 3054 is stored under the surface of the toilet seat body 3051, flush with the surface of the toilet seat body 3051, reducing the discomfort caused to the human body by the protrusion.

[0141] The problem of water leakage during flushing and cleaning is solved by introducing the airbag 3052 structure and configuring the fixed area and the contact area 3054. The airbag 3052 can fit the human body when inflated, forming a limiting area to block the flow of water, effectively preventing water from leaking out, and avoiding the problem of wetting the mattress around the toilet bowl 301 and causing pollution.

[0142] like Figure 6 As shown, after the bedpan 301 is installed on the two-toilet nursing bed, a urine shield needs to be installed on the rear end of the bedpan 301 to meet the patient's urination and defecation needs in a supine position. A nozzle can be installed on the urine shield to spray water or output dry air to clean or dry the patient's body. When spraying water to clean the patient's body, the water attached to the body will flow along the legs to the outside of the opening range of the bedpan 301. In this embodiment, the airbag 3052 connected to the toilet seat body 3051 is expanded to fit the patient's body, so that the fitting position encloses a limited area to block the flow of water. After the water flows to contact the airbag 3052, it is blocked by the airbag 3052 and flows downward into the bedpan 301, preventing the water from flowing along the body to the outside of the opening range of the bedpan 301, thereby reducing the pollution caused by water leakage.

[0143] It can be understood that in this embodiment, after the toilet seat body 3051 is installed on the toilet bowl 301, other positions on the surface of the toilet seat body 3051 where the airbag 3052 is not installed serve as bearing positions, and the airbag 3052 is used together with the mattress of the two-defecation nursing bed to bear the user. In the standby state, the airbag 3052 is tightened and fits the toilet bowl 301 body, which minimizes the contact with the human buttocks and ensures the comfort of lying in bed; in the defecation state, the airbag 3052 is inflated and fits tightly with the buttocks, providing defecation support and waterproof and anti-fouling effects for the buttocks. The surface of the airbag 3052 is not easy to stick to dirt, and can be scrubbed and cleaned, and can be dried.

[0144] Since the position where the airbag 3052 contacts the user's body is relatively long, different areas of the human body need to provide different support forces to ensure comfort. In this regard, in the present embodiment, the airbag 3052 is designed to have a structure containing multiple chambers. Each chamber is connected to the pressure gas source through a sub-control valve to achieve independent control. The chamber is connected to the sub-control valve through an air pipe to achieve gas input and output. In order to achieve the air pressure change in the chamber of the airbag 3052, an air pressure sensor is connected in series on the air pipe to monitor the air pressure change in the chamber in real time. The air pressure sensor sends the collected air pressure information to the controller, and the controller regulates the airbag 3052 based on this information.

[0145] The chamber is connected to the sub-control valve through an air pipe to realize the input and output of gas. A pressure sensor is connected in series on the air pipe to monitor the pressure change in the chamber in real time. By dividing the airbag 3052 into multiple chambers and independently controlling them through the sub-control valve, precise adjustment of different areas can be achieved to improve the user's comfort and support. The introduction of the pressure sensor can monitor the pressure change in the airbag 3052 in real time, ensure the stability and safety of the airbag 3052, and avoid safety problems caused by excessively high or low pressure.

[0146] Multiple chambers are divided in sequence along the strip distribution direction of the airbag 3052 to form a multi-stage structure. Adjacent chambers are separated by diaphragms to ensure the independence and sealing of the gas.

[0147] The air pressure sensor is a component that can sense and measure gas pressure. The air pressure sensor is used to monitor the air pressure changes in the internal chamber of the airbag 3052. When the user's posture changes, his center of gravity also shifts, and the external pressure applied to different positions of the airbag 3052 also changes. When the air pressure in the airbag 3052 changes, the air pressure sensor can capture this change in real time and convert it into an electrical signal for output and send it to the controller.

[0148] The controller is used to determine the state of the airbag 3052 based on the received air pressure information. For example, when the air pressure is lower than the preset value, the controller may determine that the airbag 3052 needs to be inflated; and when the air pressure is higher than the preset value, it may determine that the airbag 3052 needs to be deflated. Based on the judgment result, the controller will issue instructions to the inflation or deflation system of the airbag 3052. These instructions can be used to control the airbag 3052 through actuators such as sub-control valves. During the control process, the controller may also continuously obtain feedback information through the air pressure sensor to adjust the accuracy and execution effect of the instructions. For example, if the air pressure in the airbag 3052 is still lower than the preset value after inflation, the controller will increase the duration or intensity of the inflation instruction to keep the airbag 3052 in close contact with the user's body.

[0149] like Fig.11 As shown, the airbags 3052 are distributed along the toilet seat body 3051 to form a U-shaped structure, covering most of the area of ​​the toilet seat 305. At the opening position at one end of the toilet hole 3053, the part without the airbags 3052 forms a mounting portion for mounting a urine shield. The design of the U-shaped airbags 3052 can better adapt to the shape of the toilet seat 305 and the user's posture, improving the comfort and convenience of use. At the same time, the setting of the mounting portion also facilitates the installation of accessories such as a urine shield, increasing the functionality and practicality of the product.

[0150] When the airbag 3052 is stored, its side can be folded and placed between the contact area 3054 and the fixed area to reduce the occupied space. In the different stages of non-defecation, defecation and post-defecation cleaning, as well as washing and drying the airbag 3052, the airbag 3052 adapts by expanding or contracting.

[0151] When the airbag 3052 is in the storage state, the side of the airbag 3052 is folded and stored in the space between the contact area 3054 and the fixed area, making the entire airbag 3052 structure more compact and not occupying additional space. When the airbag 3052 is not in use, the surface of the toilet seat 305 remains flat, and the bulge of the airbag 3052 will not cause discomfort to the user or affect the appearance. After the side of the airbag 3052 is folded and stored, the contact area with the external environment is reduced, thereby reducing the risk of contamination. When the airbag 3052 is cleaned and dried, the folded and stored structure of the airbag 3052 makes the cleaning process simpler and more convenient, and the squeezing effect during the contraction process can more easily remove stains and residual moisture. When the airbag 3052 is stored, the side of the airbag 3052 is folded between the contact area 3054 and the fixed area, reducing the wear and deformation caused by frequent expansion and contraction, thereby improving the durability and service life of the airbag 3052. It also helps maintain the shape and elasticity of the airbag 3052, ensuring that it can expand quickly and effectively and fit the human body when needed.

[0152] like Fig.11As shown, on the surface of the toilet seat body 3051, a plurality of pressure sensors 3055 are arranged in sequence around the toilet hole 3053. These pressure sensors 3055 are also connected to the controller to monitor the user's usage status and comfort. The pressure sensors 3055 can sense the pressure distribution of the contact surface between the user and the toilet seat 305 in real time. When the user lies flat and the body contacts the toilet seat 305, the weight and posture will cause different pressure distribution patterns. These pressure data are captured by the sensor and converted into electrical signals, which are then processed and analyzed by the electronic system.

[0153] The pressure sensor 3055 surrounds the vent 3053. According to the principle of ergonomics, the sensor is arranged at key stress points, such as the buttocks and the thigh root, to obtain more comprehensive pressure distribution data. The sensor converts the captured pressure data into an electrical signal and transmits it to the data acquisition module via wired or wireless means. The data acquisition module amplifies, filters and digitally processes the received electrical signal to extract useful pressure distribution information. The analysis results are presented to users or product developers in an intuitive manner (such as charts, reports, etc.), providing data support for product optimization and personalized customization.

[0154] Based on the analysis results, the shape, material, and layout of the airbag 3052 of the toilet seat 305 can be optimized, and the pressure of the airbag 3052 chamber at the corresponding position can be adjusted according to the pressure distribution to improve the comfort and support of the toilet seat 305 for defecation and urination care.

[0155] The working method of toilet ring 305 includes: When not defecating, the air pressure in the airbag 3052 is reduced to shrink the airbag 3052, and the contact area 3054 is accommodated in the fixed area, and the surface of the contact area 3054 is flush with the surface of the toilet seat body 3051; During defecation and post-defecation cleaning, the air pressure in the airbag 3052 is increased to expand the airbag 3052, and the contact area 3054 gradually moves away from the fixed area, so that the airbag 3052 protrudes from the surface of the toilet seat body 3051, and the contact area 3054 fits the user's body to block the leakage of water; After the human body is cleaned, the airbag 3052 is cleaned and dried, and the air pressure in the airbag 3052 is reduced to shrink the airbag 3052 and return to the storage state.

[0156] After the airbag 3052 is inflated, the contact area 3054 can form a U-shaped curve to adapt to the user's body surface, and form a closed curve in combination with the external urine shield to prevent the leakage of cleaning water.

[0157] The airbag 3052 is flush with the surface of the toilet seat body 3051 in the stored state, which does not cause discomfort or foreign body sensation to the user. When it is needed, the airbag 3052 can expand quickly and fit the human body to form an effective limiting area to block the flow of water, thereby improving the comfort and satisfaction of the user.
