Description

Technical Field

[0001] This invention relates to the field of nursing bed technology, specifically to an intelligent dynamic pressure ulcer prevention nursing bed. Background Technology

[0002] In the clinical and home care settings for long-term bedridden patients, pressure ulcer prevention is a core element in ensuring the quality of patient recovery and quality of life. As a key piece of equipment for daily rest, positioning, and rehabilitation care for bedridden patients, the pressure ulcer prevention control capabilities, the ease of disassembly and maintenance of components, and the stability of connections directly affect the efficiency of care work and the safety of patient use.

[0003] Current pressure ulcer prevention and control in nursing beds primarily rely on tilting the entire bed surface and inflating / deflating fixed sections of the air mattress. Pressure adjustment depends on manual operation by caregivers or pre-set cycles, failing to accurately adjust pressure points based on real-time changes in the patient's posture. This makes it difficult to continuously distribute concentrated pressure on specific areas, significantly limiting the precision and intelligence of pressure ulcer prevention care. Furthermore, the bed board and lifting drive components are often assembled using bolts or welding, requiring specialized tools for disassembly and replacement, making the process cumbersome. Conventional snap-fit ​​connections are prone to loosening and displacement under the load of reciprocating bed movement, failing to guarantee long-term stability and reliability. Therefore, this paper proposes an intelligent dynamic pressure ulcer prevention nursing bed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent dynamic pressure ulcer prevention and care bed, which solves the technical problems of significant limitations in the accuracy and intelligence level of pressure ulcer prevention and care, as well as the inability to guarantee a stable and reliable connection status over a long period of time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent dynamic pressure ulcer prevention and care bed, comprising:

[0006] The bed frame and the headboard are set on the side of the bed frame. Cameras are evenly distributed on the side of the headboard, and a main control circuit board is added in the inner cavity of the headboard. A bed base is added to the bottom of the bed frame, and bed legs are installed at the four corners of the bottom of the bed base.

[0007] The electric lifting rods are evenly distributed on the top of the bed base. A plug-in tube is added directly above the lifting end of the electric lifting rod, and an anti-slip handle is rotatably connected to the bottom of the plug-in tube. Side through grooves are opened on both sides of the plug-in tube, and a side clamping plate is rotatably connected to the inner cavity of the side through groove. A torsion spring is added between the rotating end of the side clamping plate and the side through groove, and inclined guide plates are installed on the inner side of the side clamping plate.

[0008] The lead screw is rotatably connected to the center of the inner cavity of the plug-in cylinder via a bearing, and the end of the lead screw is coaxially connected to the anti-slip handle. A tapered slider that is narrow at the top and wide at the bottom is threaded onto the surface of the lead screw, and the tapered slider slides against the inclined surface of the inclined guide plate. The tapered slider slides against the inner wall of the plug-in cylinder.

[0009] A fixed cylinder is installed over the outside of the plug-in cylinder, and the inner wall of the fixed cylinder is provided with a side slot that is compatible with the side card plate. A splicing bed board is installed on the top of the fixed cylinder, and a splicing soft pad is added to the top of the splicing bed board.

[0010] When assembling the splicing bed board and the lifting electric rod, align the fixed cylinder with the top of the plug-in cylinder and insert it. Rotate the anti-slip handle to drive the lead screw to rotate synchronously. When the lead screw rotates, it drives the conical slider to slide upward along the inner cavity of the plug-in cylinder. During the upward sliding of the conical slider, the inclined guide plate pushes the side clamping plates on both sides to rotate outward around the rotating end of the side through groove, so that the side clamping plates are locked into the side clamping grooves on the inner wall of the fixed cylinder, thus completing the locking and fixing of the fixed cylinder and the plug-in cylinder, and realizing the assembly of the splicing bed board and the lifting electric rod.

[0011] To disassemble the bed board, rotate the anti-slip handle in the opposite direction, causing the lead screw to rotate in the opposite direction. This drives the conical slider to slide downwards along the inner cavity of the insertion cylinder. Under the reset force of the torsion spring, the side clamping plate rotates inwards around the rotating end of the side through groove, causing the side clamping plate to disengage from the side clamping groove. This releases the locking limit between the fixed cylinder and the insertion cylinder, allowing the fixed cylinder along with the bed board to be removed from the insertion cylinder.

[0012] After the patient lies on the interlocking soft pad, the camera captures real-time images of the patient's lying posture and the pressure areas on their body. The captured information is transmitted to the main control circuit board. The main control circuit board identifies the pressure points and duration on the patient's body based on the received information, and controls the corresponding lifting electric rod to perform the lifting action. The lifting electric rod drives the plug-in cylinder, fixed cylinder, interlocking bed board and interlocking soft pad to rise and fall synchronously, adjusting the support height of the interlocking soft pad at the corresponding position, changing the pressure area and pressure state of the patient's body, and realizing dynamic pressure ulcer prevention care.

[0013] Preferably, the bed base has vertically oriented through holes at each of its four corners, and electric lifting rods and guide rods are respectively installed on the surfaces of the bed legs. The bed base, through the vertically oriented through holes at its four corners, accommodates the vertical movement of the electric lifting rods and guide rods. The bed legs provide a stable mounting base for the electric lifting rods and guide rods, and the electric lifting rods and guide rods transmit their movements along the vertical direction of the through holes.

[0014] Preferably, the electric lifting rod and guide rod on the bed support legs are positioned opposite each other, and the lifting end of the electric lifting rod and the top of the guide rod are connected to the four bottom corners of the bed frame through through holes. The electric lifting rod outputs lifting driving force, driving the bed frame to complete the vertical lifting adjustment action. The guide rod slides vertically in sync with the lifting action of the bed frame, providing auxiliary guiding support for the lifting action of the bed frame.

[0015] Preferably, the top of the bed base is evenly provided with insertion slots, and insertion blocks are inserted and connected into the inner cavity of the insertion slots. The insertion slots provide limiting space for the insertion and installation of the insertion blocks. The insertion blocks are assembled and positioned with the bed base by inserting into the inner cavity of the insertion slots, and can also be disassembled and separated by detaching from the insertion slots.

[0016] Preferably, the bottom end of the lifting electric rod is connected to the top of the plug-in block, and the cross-section of the inner cavity of the plug-in slot and the entire plug-in block are both square in design. The lifting electric rod completes its assembly and positioning with the bed base as the plug-in block is inserted. The square design of the plug-in slot and the plug-in block restricts the circumferential rotation of the plug-in block, and the lifting electric rod outputs vertical lifting driving force to complete the corresponding action.

[0017] Preferably, each lifting end of the electric lifting pole is equipped with a connecting plate, and the connecting plate is circular in design. The lifting end of the electric lifting pole drives the connecting plate to complete the vertical lifting displacement. The connecting plate provides a load-bearing foundation for the installation and docking of the upper connected components, and transmits the lifting driving force synchronously with the movement of the electric lifting pole.

[0018] Preferably, a fixed side plate is installed on each of the bottom sides of the plug-in tube, and the fixed side plate has a semi-circular design. The fixed side plate provides bottom docking support for the plug-in tube, and the semi-circular design of the fixed side plate is adapted to the contour of the corresponding docking component to complete the docking assembly of the plug-in tube and the lower supporting component.

[0019] Preferably, the bottom of the fixed side plate corresponds to the top edge of the connecting plate, and the fixed side plate and the connecting plate are inserted into each other. The fixed side plate and the connecting plate are assembled and positioned by the insertion connection, and the insertion tube is connected to the lifting end of the lifting electric rod. The lifting action of the lifting electric rod is transmitted to the insertion tube through the connecting plate and the fixed side plate, driving the insertion tube to complete the vertical lifting adjustment.

[0020] Preferably, the modular bed panels are evenly distributed within the inner cavity of the bed frame, and the edges of adjacent modular bed panels are fitted together. The modular bed panels are arranged and assembled within the inner cavity of the bed frame, and adjacent modular bed panels form a continuous load-bearing plane through edge-fitting, providing a stable support foundation for the upper load-bearing structure.

[0021] Preferably, the upper edges of the splicing pads are all chamfered, and the edges of adjacent splicing pads fit together. After the splicing pads are arranged and assembled, the edges of adjacent splicing pads fit together to form a continuous flexible bearing surface, and the chamfered structure of the upper edges forms a smooth transition area, adapting to the user's contact and use needs.

[0022] Compared with the prior art, the present invention provides an intelligent dynamic pressure ulcer prevention and care bed, which has the following beneficial effects:

[0023] This intelligent dynamic pressure ulcer prevention bed uses multiple independently set lifting electric rods to correspond to a single set of spliced ​​bed boards and spliced ​​soft pads. Combined with the real-time monitoring and control of human posture by the camera on the headboard and the main control circuit board, it can realize dynamic zoned lifting and adjustment of the pressure points of the human body, accurately disperse concentrated pressure in local areas of the body, continuously avoid conditions that cause pressure ulcers, and improve the intelligence and accuracy of pressure ulcer prevention care.

[0024] By nesting the plug-in cylinder and the fixed cylinder, combined with the anti-slip rotating handle and the coaxial drive screw driving the conical slider to move, and the push-up inclined guide plate driving the side plate to engage with the side slot, the splicing bed board and the lifting electric rod can be quickly disassembled and assembled without tools. At the same time, relying on the inclined self-locking characteristic of the conical slider, the stable and reliable engagement state is ensured, and loosening and displacement during use are avoided.

[0025] The torsion spring between the side clamp and the side through groove, together with the retraction action of the conical slider, can realize the automatic reset and disengagement of the side clamp without the need for additional unlocking operations, further simplifying the disassembly and assembly steps, while avoiding jamming problems of clamping parts, ensuring smooth and efficient disassembly and assembly operations, and adapting to the rapid operation needs of nursing scenarios.

[0026] The modular design of the bed board and the mattress, combined with a quick-release snap-fit ​​structure, allows for individual replacement of damaged or soiled mattresses and bed boards without disassembling the entire bed. This significantly reduces the complexity of nursing procedures and minimizes bed downtime, meeting the high-frequency use needs of clinical nursing. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides a technical solution: an intelligent dynamic pressure ulcer prevention and care bed, comprising: (See details) Figures 1-6 The bed frame 1 and the headboard 2 set on the side of the bed frame 1, and the headboard 2 is evenly distributed with cameras 3 on the side of the headboard 2, and the main control circuit board is also added in the inner cavity of the headboard 2. The bed base 4 is added to the bottom of the bed frame 1, and the bed support legs 5 are installed at the four corners of the bottom of the bed base 4.

[0036] The lifting electric rod 10 is evenly distributed on the top of the bed base 4. A plug-in tube 12 is added directly above the lifting end of the lifting electric rod 10. An anti-slip handle 14 is rotatably connected to the bottom of the plug-in tube 12. Side through grooves 15 are opened on both sides of the plug-in tube 12. A side clamping plate 16 is rotatably connected to the inner cavity of the side through groove 15. A torsion spring is added between the rotating end of the side clamping plate 16 and the side through groove 15. Inclined guide plates 17 are installed on the inner side of the side clamping plate 16.

[0037] The lead screw 18 is rotatably connected to the center of the inner cavity of the plug-in cylinder 12 via a bearing, and the end of the lead screw 18 is coaxially connected to the anti-slip handle 14. A tapered slider 19, which is narrow at the top and wide at the bottom, is threaded onto the surface of the lead screw 18. The tapered slider 19 slides and fits against the inclined surface of the inclined guide plate 17 and slides and fits against the inner wall of the plug-in cylinder 12.

[0038] The fixed cylinder 20 is covered outside the plug-in cylinder 12, and the inner wall of the fixed cylinder 20 is provided with a side slot 21 that is compatible with the side card plate 16. The splicing bed board 22 is installed on the top of the fixed cylinder 20, and the top of the splicing bed board 22 is provided with a splicing soft pad 23.

[0039] The camera 3 collects real-time images of the patient's lying posture and pressure areas, and the main control circuit board controls the corresponding lifting electric rod 10 to perform actions. This dynamically adjusts the support height of the spliced ​​soft pad 23, changes the pressure areas on the patient's body, avoids long-term pressure on the same area, and realizes intelligent dynamic pressure ulcer prevention care, which greatly reduces the workload of nursing staff.

[0040] Through the insertion and engagement of the plug-in cylinder 12 with the fixed cylinder 20, and the linkage structure of the lead screw 18, the conical slider 19, the inclined guide plate 17 and the side clamping plate 16, the splicing bed board 22 and the lifting electric rod 10 can be quickly locked and disassembled by simply rotating the anti-slip handle 14, without the need for additional tools, which greatly improves the efficiency of equipment assembly and maintenance.

[0041] The tapered slider 19 is driven by the inclined surface of the inclined guide plate 17, and the side plate 16 is automatically reset by the torsion spring. In the locked state, the side plate 16 is stably locked in the side slot 21, which can effectively prevent loosening and displacement during use, and ensure the stability and reliability of the splicing bed board 22 support. The structure is smooth and easy to operate.

[0042] The modular design of the bed board 22 and the soft pad 23, combined with the independently controlled electric lifting rod 10, allows for independent adjustment of the support height of different parts of the patient's body, making it suitable for patients with different nursing needs. When a single component is damaged, it can be disassembled and replaced individually without replacing the entire bed, thus reducing the maintenance cost and difficulty of the equipment.

[0043] Please see Figure 2 The bed base 4 has vertical through holes at each of its four corners, and the bed legs 5 are respectively equipped with electric lifting rods 6 and guide rods 7. The through holes in the bed base 4 provide precise vertical limits for the movement of the electric lifting rods 6 and guide rods 7, preventing deviation during operation. At the same time, the bed legs 5 provide stable mounting support for the lifting-related components, ensuring stable execution of the lifting action.

[0044] The electric lifting rod 6 and guide rod 7 on the bed support 5 are positioned opposite each other, and the lifting end of the electric lifting rod 6 and the top of the guide rod 7 are connected to the four bottom corners of the bed frame 1 through through holes. By using the oppositely positioned electric lifting rod 6 and guide rod 7, the force on the bed frame 1 during the lifting process is balanced, preventing the bed frame 1 from tilting to one side, ensuring the stability of the lifting adjustment process of the bed frame 1, and improving the guiding accuracy of the lifting action.

[0045] Please see Figure 3 and Figure 4 The top of the bed base 4 is evenly provided with insertion slots 8, and insertion blocks 9 are inserted and connected to the inner cavity of the insertion slots 8. Through the insertion and cooperation of the insertion slots 8 and the insertion blocks 9, the relevant components can be quickly disassembled and assembled with the bed base 4 without complicated fixing procedures. At the same time, it provides stable positioning support for the upper components and avoids displacement after assembly.

[0046] The bottom end of the lifting electric rod 10 is connected to the top of the plug-in block 9, and the cross-section of the inner cavity of the plug-in groove 8 and the entire plug-in block 9 are both square. The square plug-in groove 8 and the plug-in block 9 work together to effectively prevent circumferential rotation of the plug-in block 9 after assembly, ensuring the installation stability of the lifting electric rod 10. At the same time, it allows for quick assembly and disassembly of the lifting electric rod 10 and the bed base 4, improving the convenience of assembly and maintenance.

[0047] Please see Figure 5 Each lifting electric pole 10 has a connecting plate 11 installed at its lifting end, and the connecting plate 11 has an overall circular design. The connecting plate 11 enables a smooth connection between the lifting electric pole 10 and the upper component, expands the contact area for transmitting the lifting driving force, avoids stress concentration, and the circular design of the connecting plate 11 is suitable for the installation requirements of various docking structures, thus improving the adaptability of the structure.

[0048] Each bottom side of the plug-in tube 12 is equipped with a fixed side plate 13, and the fixed side plate 13 has a semi-circular design. The fixed side plate 13 provides a stable installation and docking structure for the plug-in tube 12. The semi-circular design of the fixed side plate 13 can form a close fit with the corresponding docking parts, improving the fit and structural stability after assembly and preventing the plug-in tube 12 from shaking.

[0049] The bottom of the fixed side plate 13 corresponds to the top edge of the connecting plate 11, and the fixed side plate 13 and the connecting plate 11 are inserted and connected. Through the insertion and connection of the fixed side plate 13 and the connecting plate 11, the quick assembly and disassembly of the plug-in tube 12 and the lifting electric rod 10 can be achieved without complicated assembly procedures, while ensuring the stable transmission of lifting driving force and improving the convenience of structural assembly and maintenance.

[0050] The interlocking bed panels 22 are evenly distributed within the inner cavity of the bed frame 1, and the edges of adjacent interlocking bed panels 22 are fitted together. Through the fitted arrangement of multiple interlocking bed panels 22, a detachable bed panel load-bearing structure is formed, which facilitates the replacement and maintenance of individual interlocking bed panels 22. At the same time, the fitted design of adjacent edges ensures the flatness of the load-bearing surface, avoids load-bearing gaps, and improves the stability of the support.

[0051] The upper edges of the splicing pads 23 are all chamfered, and the edges of adjacent splicing pads 23 are fitted together. By fitting the edges of adjacent splicing pads 23 together, the flatness of the flexible bearing surface is ensured, avoiding jamming or bumping during use. The chamfered design of the upper edges eliminates sharp corners at the splicing points, improving comfort and safety during use.

[0052] This solution involves inserting the connector 9 into the inner cavity of the connector slot 8 at the top of the bed base 4 to complete the assembly and positioning of the lifting electric rod 10 with the bed base 4. The fixed side plate 13 is then inserted and connected to the connecting plate 11 to complete the docking assembly of the connector cylinder 12 with the lifting end of the lifting electric rod 10. Insert the fixed cylinder 20 into the top of the plug-in cylinder 12, rotate the anti-slip handle 14 to drive the lead screw 18 to rotate synchronously. When the lead screw 18 rotates, it drives the conical slider 19 to slide upward along the inner cavity of the plug-in cylinder 12. During the upward sliding process, the conical slider 19 pushes the side clamping plates 16 on both sides to rotate outward around the rotating end of the side through groove 15 through the inclined guide plate 17, so that the side clamping plates 16 are inserted into the side clamping groove 21 on the inner wall of the fixed cylinder 20, thus completing the locking and fixing of the fixed cylinder 20 and the plug-in cylinder 12, realizing the assembly of the splicing bed board 22 and the lifting electric rod 10. After multiple sets of splicing bed boards 22 and splicing soft pads 23 are assembled in this way, they are arranged in the inner cavity of the bed frame 1 to form a complete bearing plane.

[0053] After the assembly of all bed components is completed, the core control and calculation module of the main control circuit board receives the bed height adjustment command input from the outside, coordinates the operation sequence of each module, and transmits the control command to the drive execution module. After receiving the control command, the drive execution module converts it into an appropriate drive electrical signal and outputs it to the electric lifting rod 6. The electric lifting rod 6 outputs lifting drive force, which drives the bed frame 1 to complete the vertical lifting adjustment along the guide direction of the guide rod 7. The status monitoring and feedback module of the main control circuit board collects the operating status and position information of the electric lifting rod 6 in real time and feeds it back to the core control and calculation module to complete the closed-loop verification and control of the bed height adjustment.

[0054] After the patient lies down on the spliced ​​soft cushion 23, the camera 3 on the side of the headboard 2 collects real-time image information of the patient's lying posture and the pressure area of ​​the body, and transmits the collected information to the main control circuit board. The image acquisition and processing module of the main control circuit board receives the image information transmitted by the camera 3, completes image preprocessing, patient lying posture recognition, body pressure location and pressure duration statistics, and transmits the processed effective data to the core control and computing module.

[0055] After receiving and processing the patient's body pressure data, the core control and calculation module generates a lifting control command for the corresponding position of the electric lifting rod 10 according to the preset pressure ulcer prevention control logic. The control command is then transmitted to the drive execution module. After receiving the control command, the drive execution module converts it into a corresponding drive electrical signal and outputs it to the electric lifting rod 10 at the corresponding position. The electric lifting rod 10 performs the lifting action, driving the plug-in cylinder 12, the fixed cylinder 20, the spliced ​​bed board 22, and the spliced ​​soft pad 23 to rise and fall synchronously, adjusting the support height of the spliced ​​soft pad 23 at the corresponding position, and changing the pressure area and pressure state of the patient's body.

[0056] The status monitoring and feedback module of the main control circuit board collects the operating status and position information of each lifting electric rod 10 in real time and feeds it back to the core control and calculation module. It performs closed-loop verification and correction on the action execution of the lifting electric rod 10 to ensure the accuracy of the support height adjustment. The camera 3 continuously collects image information of the patient's lying posture and the pressure area of ​​the body. The main control circuit board continuously completes data processing and control command output, and cyclically executes the support height adjustment of the spliced ​​soft pad 23 at the corresponding position to achieve continuous dynamic pressure ulcer prevention care. The human-computer interaction and communication module of the main control circuit board displays the equipment operating status and patient pressure care data in real time, supports nursing staff to adjust control parameters, and reserves a data communication interface to complete the transmission of equipment operating data and docking with external systems.

[0057] When it is necessary to disassemble and replace the splicing bed board 22 and splicing soft pad 23, rotate the anti-slip handle 14 in the opposite direction to drive the lead screw 18 to rotate in the opposite direction, drive the conical slider 19 to slide downward along the inner cavity of the plug-in cylinder 12, and the side clamping plate 16 rotates inward around the rotating end of the side through groove 15 under the reset force of the torsion spring, so that the side clamping plate 16 is disengaged from the side clamping groove 21, releasing the locking limit between the fixed cylinder 20 and the plug-in cylinder 12, and removing the fixed cylinder 20 along with the splicing bed board 22 and splicing soft pad 23 from the plug-in cylinder 12 to complete the disassembly of the corresponding parts. When it is necessary to disassemble and maintain the lifting electric rod 10, pull out the plug block 9 from the inner cavity of the plug groove 8 to complete the separation and disassembly of the lifting electric rod 10 and the bed base 4.
