Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a lifting structure for a nursing bed commode. Background Technology

[0002] Nursing beds are mostly used by people in the recovery period or those with limited mobility. They are assistive devices that can help patients recover, reduce their pain, and improve the efficiency of patient care.

[0003] Adding a defecation function to the nursing bed allows patients to defecate normally while in bed, alleviating the discomfort caused by getting in and out of bed to defecate. To achieve this, a bedpan needs to be installed in the bed frame. When in use, a bedpan is placed below the bedpan; when not in use, the bedpan is closed by a sealing structure.

[0004] Most nursing beds nowadays use independent support and height adjustment structures to allow the support at the commode opening to be moved out and the bedpan to be moved up. The two structures are used independently, which is inconvenient to operate and the overall structure is relatively complex, making production and maintenance difficult. Summary of the Invention

[0005] The purpose of this invention is to provide a lifting structure for a nursing bed commode, so as to alleviate the technical problems of the existing technology where the independent support structure and height adjustment structure are used independently, which is inconvenient to operate, and the overall structure is relatively complex, making production and maintenance difficult.

[0006] The present invention provides a lifting structure for a nursing bed commode, comprising: a mounting component, a guide component, a drive component, a support component, and a lifting component.

[0007] The mounting bracket is used to connect the bed frame, and the surface of the mounting bracket has a toilet hole.

[0008] The guide assembly has a rotating guide and a pushing guide, which are connected and communicate with each other.

[0009] The drive assembly includes a transmission component that is adapted to the guide assembly.

[0010] The support component is connected to the drive assembly via transmission.

[0011] The lifting assembly includes a moving end and a holding part. The moving end is located between the rotating guide and the pushing guide so that the moving end can be driven to move when the transmission part moves along the pushing guide. The holding part is connected to the moving end in a transmission manner to move closer to or further away from the toilet hole.

[0012] When the support is placed in the toilet hole, the transmission component is located on the side of the rotation guide that is away from the push guide, and the holding component is away from the toilet hole.

[0013] Furthermore, the guiding components include: a first track and a second track.

[0014] The first track includes a turning section and a straight section, with the turning section and the straight section set at an angle.

[0015] The second track is parallel to the straight segments of the first track and is spaced apart.

[0016] The transmission component has a first transmission end and a second transmission end, the first transmission end moves along a first track, and the second transmission end moves along a second track.

[0017] The mobile terminal is located at the junction of the turning section and the straight section.

[0018] Furthermore, the bedpan lifting structure also includes an auxiliary slide.

[0019] The auxiliary slide is located on the mounting component.

[0020] The drive assembly also includes a movable shaft, which is located in an auxiliary slide and is connected to the transmission component.

[0021] The support is located on the moving shaft.

[0022] Furthermore, the drive component also has a rotating end.

[0023] The rotating end is connected to the moving shaft via a transmission.

[0024] When the support is placed in the urinal hole, the rotating end, the first transmission end and the second transmission end are arranged sequentially along the moving direction of the transmission component, and the rotating end, the first transmission end and the second transmission end form a triangular structure, with the position of the first transmission end higher than that of the transmission end and the second transmission end.

[0025] Furthermore, the lifting assembly includes a folding frame.

[0026] The mobile device is located on the folding shelf.

[0027] The folding frame has a fixed end, which is located on the side of the folding frame closer to the moving end, and the fixed end is rotatably connected to the mounting component.

[0028] The container is located on the side of the folding frame away from the moving end, and the direction of movement of the container is at an angle to both the horizontal and vertical directions.

[0029] Furthermore, the mobile device is equipped with a card slot.

[0030] The snap-fit ​​part is adapted to the moving shaft.

[0031] When the transmission component moves along the push guide, the moving shaft engages with the locking part to push the moving end to move.

[0032] Furthermore, the folding frame includes a first rotating arm and a second rotating arm.

[0033] One end of the first rotating arm is a fixed end.

[0034] One end of the second rotating arm is a movable end, and the second rotating arm is arranged to cross the first rotating arm and is hinged at the intersection.

[0035] The other end of the first rotating arm and the other end of the second rotating arm are both located on the container and slide in cooperation with the container.

[0036] Furthermore, the length of the second rotating arm is greater than the length of the first rotating arm.

[0037] When the support is placed in the urinal, the container is located below one end of the mounting component.

[0038] Furthermore, the guide components also have overlapping sections.

[0039] The overlapping part is located on the side of the rotating guide that is away from the pushing guide and is connected to the rotating guide.

[0040] The mounting piece is equipped with an overlap piece, which is located on one side of the toilet hole.

[0041] When the support is placed in the urinal hole, the transmission component is located at the overlapping part, and the bottom surface of the end of the support overlaps with the top surface of the overlapping part.

[0042] The transmission component moves from the overlapping part to the rotation guide part and then moves toward the pushing guide part. The support component moves along the overlapping part and then flips toward the side of the mounting component closer to the holding part.

[0043] Furthermore, both the drive assembly and the guide assembly are located below the mounting component.

[0044] The drive end of the drive assembly is rotatably connected to the mounting component, and the axis of the rotatable connection is perpendicular to the extension direction of the guide assembly.

[0045] Beneficial effects: In this invention, the mounting component connects to the bed frame of the nursing bed, allowing the bedpan lifting structure to be stably mounted on the bed frame. The drive component outputs power and, through the transmission component, switches the gears of the bedpan lifting mechanism. The guide component guides the movement of the transmission component, enabling it to flip under the guidance of the rotating guide. This allows the support component to flip along with the movement of the transmission component, thus filling or disengaging from the urinal. Driven by the drive component, the transmission component connects with the moving end of the lifting component when it moves to the push guide. This allows for smooth connection of the drive to the lifting component after the support component flips to disengage from the urinal. Driven by the moving end, the container holding the bedpan moves toward the urinal. When the transmission component moves to the end of the push guide, the bedpan carried by the container connects with the urinal for use. This invention achieves the flipping and storage of the support and the movement control of the container by cooperating with a separate transmission component and a guide assembly. The two actions are smoothly connected and in a reasonable sequence, making operation very convenient. The overall structure is simple and can reduce the difficulty of production and maintenance.

[0056] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0057] See Figures 1 to 5 The nursing bed commode lifting structure provided in this embodiment includes an installation component 100, a guide component 200, a drive component 300, a support component 400, and a lifting component 500.

[0058] Mounting member 100 is used to connect to the bed frame, and a toilet hole 101 is formed on the surface of mounting member 100.

[0059] Combination Figure 7The guide assembly 200 has a rotating guide portion 201 and a pushing guide portion 202, which are connected and communicate with each other. The drive assembly 300 includes a transmission member 310, which is adapted to the guide assembly 200. The support member 400 is drivenly connected to the drive assembly 300. The lifting assembly 500 includes a moving end 510 and a holding member 520. The moving end 510 is located between the rotating guide portion 201 and the pushing guide portion 202, so that when the transmission member 310 moves along the pushing guide portion 202, it can drive the moving end 510 to move. The holding member 520 is drivenly connected to the moving end to move closer to or further away from the toilet hole 101.

[0060] Specifically, the bedpan lifting structure provided in this embodiment has an initial position, a first position, and a second position.

[0061] Please refer to it again. Figure 1 When the bedpan lifting structure is in the initial position, the support 400 is located in the urinal hole 101, the transmission 310 is located on the side of the rotation guide 201 away from the push guide 202, and the holding part 520 is away from the urinal hole 101.

[0062] When shifting from the initial gear to the first gear, the transmission member 310 moves from the rotation guide 201 toward the push guide 202, thereby causing the support member 400 to flip toward the side of the mounting member 100 closer to the holding member 520.

[0063] Combination Figure 2 , Figure 2 In the middle, the lifting structure of the commode bed is in the first position, that is, the transmission component 310 is located at the junction of the rotation guide 201 and the push guide 202. At this time, the support component 400 completes the flipping action, and the position of the holding component 520 remains unchanged.

[0064] When shifting from the first gear to the second gear, the transmission component 310 moves along the push guide 202 to drive the moving end 510 to move, and the holding component 520 moves toward the toilet hole 101.

[0065] Combination Figure 3 , Figure 3 In the middle, the lifting structure of the bedpan is in the second position, that is, the transmission component 310 is located at the end of the push guide 202 away from the rotation guide 201. At this time, the support component 400 completes the flipping action and moves to the side of the mounting component 100 under the drive of the transmission component 310, and the holding component 520 moves up so that the bedpan can be moved up into the toilet hole.

[0066] In this embodiment, the mounting component 100 is installed on the bed frame of the nursing bed, so that the bedpan lifting structure can be stably installed on the bed frame. The drive component 300 drives the support component 400 and the holding component 520 to move through the transmission component 310, so as to realize the gear switching of the bedpan lifting mechanism.

[0067] During the movement of the transmission member 310, the guide component 200 can guide the movement of the transmission member 310, so that the transmission member 310 can achieve a flipping action under the guidance of the rotation guide 201, so that the support member 400 can follow the movement of the transmission member 310 to flip, thereby achieving filling or disengagement from the toilet hole 101.

[0068] Driven by the drive assembly 300, the transmission member 310 connects with the moving end 510 of the lifting assembly 500 when it moves to the push guide 202, so that the drive of the lifting assembly 500 can be smoothly connected after the drive support member 400 flips to disengage from the toilet hole 101.

[0069] The transmission component 310 enters the push guide 202 and pushes the moving end 510 to move. Driven by the moving end 510, the container 520 holding the bedpan moves toward the toilet hole 101. When the transmission component 310 moves to the end of the push guide 202, it stops moving. At this time, the bedpan carried by the container 520 is connected to the toilet hole 101 so that the patient on the bed can use it.

[0070] After the bedpan is used, the control drive assembly 300 causes the transmission component 310 to move back to its original position. The moving end 510 follows the transmission component 310 back to its original position, and the holding component 520 moves back to its initial position under the drive of the moving end 510. When the transmission component 310 moves again to the junction of the rotating guide 201 and the pushing guide 202, the holding component 520 falls back to its initial position. Subsequently, the transmission component 310 moves back to its original position along the rotating guide 201, so as to drive the support component 400 to flip back into the toilet hole 101 to support the patient.

[0071] In this embodiment, the rotation and storage of the support 400 and the movement control of the container 520 are achieved by the cooperation of the separate transmission component 310 and the guide component 200. The two actions are smoothly connected and in a reasonable sequence, making the operation very convenient. The overall structure is simple and can reduce the difficulty of production and maintenance.

[0072] Combination Figure 4 ,to Figure 6 In this embodiment, the guide component 200 includes a first track 210 and a second track 220. The first track 210 includes a turning segment 211 and a straight segment 212, with the turning segment 211 and the straight segment 212 arranged at an angle. The second track 220 is parallel to and spaced apart from the straight segment 212 of the first track 210.

[0073] The transmission component 310 has a first transmission end 311 and a second transmission end 312. The first transmission end 311 moves along the first track 210, and the second transmission end 312 moves along the second track 220. The moving end 510 is located at the junction of the turning section 211 and the straight section 212.

[0074] Specifically, in this embodiment, both the first track 210 and the second track 220 are disposed below the end of the mounting member 100. The steering segment 211 is inclined upward relative to the horizontal plane from away from and towards the straight segment 212. The straight segment 212 is parallel to the horizontal plane. The second track 220 is a straight track and is parallel to and spaced apart from the straight segment 212. In this embodiment, the first end of the transmission member 310 is provided with a first connecting portion that inserts into the first track 210 in the horizontal direction, and the second end of the transmission member 310 is provided with a second connecting portion that inserts into the second track 220 in the horizontal direction.

[0075] In this structure, when the drive assembly 300 drives the transmission member 310 to switch from the initial gear to the first gear, the second transmission end 312 remains stationary, and the first transmission end 311 moves with the first connecting part in the turning section 211 of the first track 210 so that the first transmission end 311 rotates around the second transmission end 312. Under this action, the support member 400 follows the movement of the transmission member 310 to achieve flipping.

[0076] When the drive assembly 300 drives the transmission member 310 to switch from the first gear to the second gear, the first connecting part is located at the intersection of the turning section 211 and the straight section 212, and the second connecting part is located within the second track 220. The drive assembly 300 continues to drive the transmission member 310 to move, and the first connecting part enters the straight section 212. At the same time, the second connecting part moves in a straight line synchronously with the first connecting part. The first connecting part pushes the moving end 510 to move along the straight section 212 to drive the container 520 to move toward the toilet hole 101 until it reaches the designated position (in this embodiment, the designated position of the first connecting part is the end of the straight section 212 away from the turning section 211, and the designated position of the second connecting part is the end of the second track 220). The container 520 reaches the preset position, and the toilet bowl on the container 520 can be aligned with and connected to the toilet hole 101.

[0077] In addition, in this embodiment, the rotation angle of the support member 400 is 90°, and after the support member 400 rotates to 90° (i.e., rotates to the correct position), the support member 400 moves along the straight section 212 and the second track 220 together with the transmission member 310 and the moving end 510, so as to avoid the support member 400 from staying in the original position and colliding with the lifting component 500 and the toilet.

[0078] In this embodiment, the commode lifting structure of the nursing bed also includes an auxiliary slide 110. The auxiliary slide 110 is disposed on the mounting member 100. The drive assembly 300 also includes a moving shaft 320, which is disposed in the auxiliary slide 110 and is connected to the transmission member 310 for transmission. The support member 400 is disposed on the moving shaft 320.

[0079] Specifically, in this embodiment, there are two auxiliary slides 110 symmetrically arranged at both ends of the mounting member 100. The two auxiliary slides 110 are arranged in parallel. In this embodiment, the two ends of the moving shaft 320 are respectively provided with moving wheels. The two moving wheels are respectively arranged in the two auxiliary slides 110 and can move along the extension direction of the auxiliary slides 110.

[0080] In this embodiment, one end of the movable shaft 320 is connected to the transmission member 310 so that the movable shaft 320 can move together with the transmission member 310. One end of the support member 400 is sleeved on the movable shaft 320. The movable shaft 320 can support the support member 400 and can rotate around the movable shaft 320 when the support member 400 rotates.

[0081] In this embodiment, the conveyor also has a rotating end 313. The rotating end 313 is connected to the moving shaft 320 in a transmission connection. In the initial gear position, the rotating end 313, the first transmission end 311, and the second transmission end 312 are arranged sequentially along the moving direction of the conveyor, and the rotating end 313, the first transmission end 311, and the second transmission end 312 form a triangular structure, with the position of the first transmission end 311 higher than that of the second transmission end 312.

[0082] The rotating end 313 of the transmission component is connected to the moving shaft 320 so that the moving shaft 320 can move with the transmission component 310. The rotating end 313, the first transmission end 311 and the second transmission end 312 form a triangular structure, which is relatively stable and not easily deformed by the thrust.

[0083] Specifically, the drive assembly 300 in this embodiment further includes a drive motor, the output end of which is connected to a lead screw assembly 330. The drive structure of the lead screw is hinged to the mounting member 100, so that the lead screw assembly 330 can rotate when driving the first transmission end 311 to move along the steering section 211, thereby achieving continuous drive of the transmission member 310. A rotating shaft is inserted into the moving structure of the lead screw assembly 330, and the other end of the rotating shaft passes through the rotating end 313, so that the moving structure of the lead screw assembly 330 and the rotating end 313 are rotatably connected through the rotating shaft and can move synchronously.

[0084] In this structure, the moving structure of the drive motor drives the lead screw assembly 330 to move, thereby driving the rotating end 313 of the transmission component 310 to move.

[0085] Furthermore, in this embodiment, the transmission component 310 has a bent structure, with the rotating end 313 and the second transmission end 312 located on both sides of the first transmission end 311, respectively.

[0086] In this embodiment, the lifting assembly 500 includes a folding frame. A movable end 510 is disposed on the folding frame. The folding frame has a fixed end, which is disposed on the side of the folding frame near the movable end 510 and is rotatably connected to the mounting member 100. A holding member 520 is disposed on the side of the folding frame away from the movable end 510, and the moving direction of the holding member 520 forms an angle with both the horizontal and vertical directions.

[0087] In the initial position, the container 520 is located below one end of the mounting member 100. In the second position, the container 520 is opposite to the toilet hole 101.

[0088] In this embodiment, the movement of the container 520 is achieved through a folding frame. The fixed end of the folding frame is located on the mounting member 100 and rotatably connected to the mounting member 100. When switching from the initial position to the first position, the folding frame does not move. When switching from the first position to the second position, the moving end 510 of the folding frame moves in conjunction with the transmission member 310, and the folding frame folds to pull the container 520 toward the toilet hole 101. Similarly, when switching from the second position back to the first position, the moving end 510 and the transmission member 310 move to reset, and the folding frame extends to lower the container 520 back to its original position.

[0089] In this embodiment, the mobile end 510 is provided with a locking part. The locking part is adapted to the moving shaft 320. When moving from the first position to the second position, the moving shaft 320 cooperates with the locking part to push the mobile end 510 to move.

[0090] Combination Figure 8 Specifically, in this embodiment, the engaging part is a slot. In the initial and first positions, the slot opening is tilted upwards. When switching from the first position to the second position, the bottom end of the moving shaft 320 can abut against the slot wall to push the moving end 510 to move. During the movement of the moving end 510, the folding frame folds, and the slot rotates under the folding action so that the slot opening gradually rotates upwards. When in the second position, the moving shaft 320 can just enter the slot.

[0091] In this embodiment, the folding frame includes a first rotating arm 530 and a second rotating arm 540. One end of the first rotating arm 530 is a fixed end. One end of the second rotating arm 540 is a movable end 510. The second rotating arm 540 and the first rotating arm 530 are arranged crosswise and hinged at the intersection. The other ends of the first rotating arm 530 and the other ends of the second rotating arm 540 are both provided on the holding member 520 and slide in cooperation with the holding member 520.

[0092] Specifically, in this embodiment, the top end of the first rotating arm 530 is the fixed end, the top end of the second rotating arm 540 is the moving end 510, and the holding component 520 is provided with a sliding groove extending in the horizontal direction. The bottom ends of the first rotating arm 530 and the bottom ends of the second rotating arm 540 are both provided with sliders to achieve sliding cooperation with the sliding groove.

[0093] In this embodiment, the length of the second rotating arm 540 is greater than the length of the first rotating arm 530. When the support member 400 is disposed in the toilet hole 101, the holding member 520 is located below one end of the mounting member 100.

[0094] In this embodiment, because the length of the second rotating arm 540 is greater than the length of the first rotating arm 530, the angle between the second rotating arm 540 and the holding member 520 is smaller than the angle between the first rotating arm 530 and the holding member 520 when the folding frame is extended. The holding member 520 is located on one side of the hinge point. In this embodiment, when the telescopic frame is retracted to its final position (i.e., in the second position), the commode can be accurately moved to the toilet hole 101. In the initial position (i.e., when the folding frame is extended), the holding member 520 is located below one end of the mounting member 100. With this structure, the commode is easier to remove and place in this position, and it does not need to be placed under the bed when changing it, making it more convenient to use.

[0095] In this embodiment, the guide assembly 200 also has an overlapping portion 203. The overlapping portion 203 is provided on the side of the rotation guide portion 201 away from the push guide portion 202 and is connected to the rotation guide portion 201. The mounting member 100 is provided with an overlapping member 102, which is located on one side of the toilet hole 101.

[0096] In the initial gear position, the transmission member 310 is located at the overlapping portion 203, and the bottom surface of the end of the support member 400 overlaps with the top surface of the overlapping member 102. When moving from the initial gear position to the first gear position, the transmission member 310 moves from the overlapping portion 203 to the rotation guide portion 201 and moves toward the push guide portion 202. The support member 400 moves along the overlapping member 102 and, after disengaging from the overlapping portion 203, flips toward the side of the mounting member 100 closer to the holding member 520.

[0097] Specifically, in this embodiment, the overlapping portion 203 is disposed on the side of the rotating segment away from the straight segment 212, and the overlapping portion 203 extends horizontally away from the side of the straight segment 212.

[0098] In the initial state, the support member 400 is located in the urinal hole 101 and needs to support the patient. At this time, the first connecting part is located at the end of the overlapping part 203 away from the straight segment 212. The end of the support member 400 away from the moving axis 320 is in an overlapping state with the overlapping part 203 in the urinal hole 101. The overlapping part 203 can support the end of the support member 400, thereby improving the force-bearing capacity of the support member 400 and preventing the support member 400 from collapsing downward under pressure when supporting the patient, which would cause discomfort to the patient.

[0099] In this embodiment, the drive assembly 300, the first track 210, and the second track 220 are all located below the mounting member 100. The drive end of the drive assembly 300 is rotatably connected to the mounting member 100, and the axis of the rotatable connection is perpendicular to the extension direction of the first track 210 and the second track 220.

[0100] Specifically, in this embodiment, the drive motor and lead screw assembly 330 are located on one side of the first track 210 and the second track 220. The drive motor and lead screw assembly 330 are rotatably connected to the mounting member 100. The driving direction of the lead screw assembly 330 is the same as the extension direction of the first track 210 and the second track 220. The drive motor and lead screw assembly 330 are rotatably connected and positioned below the mounting member 100. In this embodiment, the output shaft of the drive motor is connected to the lead screw assembly 330 to achieve transmission. The lead screw assembly 330 is rotatably connected to the mounting member 100, and the axis of the rotation shaft at the rotatable connection extends horizontally and is perpendicular to the first track 210 and the second track 220. In this structure, the end of the lead screw assembly 330 away from the transmission member 310 can rotate around the rotation axis. When the moving end of the lead screw assembly 330 drives the transmission member 310 to move along the rotation guide 201, the lead screw assembly 330 can rotate slightly along the rotation axis so that the moving end of the lead screw assembly can follow the transmission member 310 to move along the inclined rotation guide 201, thereby enabling the support member 400 to perform a flipping action.

[0101] The bedpan lifting structure provided in this embodiment is applied to a nursing bed.

[0102] The bedpan lifting structure is located in the middle of the nursing bed. The mounting part 100 of the bedpan lifting structure is set along the width of the nursing bed. When the patient is resting, the patient lies on the nursing bed with the bedpan hole 101 close to the patient's waist. The support part 400 can support the patient. At this time, the holding part 520 is located below one end of the width of the nursing bed. Medical staff and relatives can place or remove the bedpan on the holding part 520 at the bedside.

[0103] When a patient needs to use the bedpan, the drive motor can be operated to retract the folding frame via the lead screw assembly 330, causing the support member 400 to flip. Subsequently, the container 520 containing the bedpan moves to the toilet hole 101 for use. After use, the drive motor can be operated again to extend the folding frame to its initial state, and the container 520 containing the bedpan moves back to its original position.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
