Description

Technical Field

[0001] The invention relates to the technical field of special nursing beds, in particular to an intelligent auxiliary lateral turning bed. Background Art

[0002] Due to skin damage, burn patients often need medical staff to turn them over during the nursing process. On the one hand, this prevents patients from maintaining the same posture for a long time, which can prevent local body tissues from being continuously compressed and blood circulation from being blocked, which can easily cause pressure sores. Regular turning can change the body's point of force, disperse the pressure, and reduce the risk of pressure sores. On the other hand, the wounds of burn patients are easily invaded by bacterial pathogens, and medical staff need to check the wounds regularly to prevent the infection from worsening.

[0003] The turning operation is usually done manually by medical staff, which is not only labor-intensive, but may also cause great pain to the patient due to improper operation. Therefore, there are some turning beds in the prior art to assist medical staff in turning the patient over and improve the work efficiency of medical staff. For example, the prior art "A medical bed for applying medicine on the side of burn patients" (Announcement No.: CN114869620B) is a method in which a motor is set on the medical bed, and a worm gear structure is used to drive the positioning seat to rotate, and then the positioning seat rotates and contacts the force-bearing roller, thereby driving the turning bed board to swing and turn up the patient's back to facilitate medical staff to apply medicine. However, the prior art still has the following technical problems:

[0004] 1. Poor comfort. The existing technology is to drive the turning bed board to swing to turn the patient over, but the bed board itself is relatively hard and flat, which is difficult to accurately fit the human body curve. The skin of burn patients is sensitive and fragile. This relatively stiff turning method may cause uneven force on the patient's body, especially on the burn wound area, which is prone to pain due to uneven pressure, and may even cause the wound to tear and aggravate the injury.

[0005] 2. Inconvenient nursing operation. The existing technology relies on the bed board to push the patient to turn over, which requires the bed board to be in contact with the patient and provide support. When medical staff want to check the wound surface, the bed board will block the wound surface and affect the medical staff's wound care. If the turning angle of the bed board is readjusted, the patient's body position will not be supported. It may be necessary for multiple medical staff to hold the patient to easily care for the wound, which is very inconvenient. Summary of the invention

[0006] The present invention provides an intelligent auxiliary lateral turning bed, which can solve the problems in the prior art that the turning bed easily causes pain to the patient during the turning operation, is not comfortable, and causes inconvenience in wound care operation.

[0007] The present application provides the following technical solution: an intelligent assisted side-turning bed, comprising a bed body, a cushion located above the bed body, and a turning cloth located above the cushion, wherein a turning mechanism is also provided on the bed body;

[0008] The turning mechanism comprises columns fixed around the bed, arc-shaped guide rails fixed on the columns, a slider slidably connected to the arc-shaped guide rails, a rope chain fixed on the slider, and a driving motor fixed at the other end of the rope chain, wherein the driving motor is located at the top of the column;

[0009] The sliders are fixed on the four corners of the turning cloth, the inner arc surface of the arc-shaped guide rail faces the turning cloth, the ends of the turning cloth are fixed with knots, and the other ends of the knots are fixed on the ends of the bed body.

[0010] Beneficial effects:

[0011] 1. Improve comfort. The present invention sets arc-shaped guide rails around the bed body, and the sliders are fixed around the turning cloth. The driving motor drives the slider to slide along the arc-shaped guide rails through the rope chain, which will drive one side of the turning cloth to be lifted. The traction force of the turning cloth when it is lifted upward can turn the patient over. Since the natural turning action of a person is a smooth curved motion process, and the design of the arc-shaped guide rails can make the traction force of the turning cloth on the patient's body make the motion trajectory of the turning process smoother. Compared with the stiff and direct turning of the bed board in the prior art, the turning cloth in the present invention can fit the body curve, so that the traction force can be evenly distributed on the patient's body, and the patient's body position is gradually changed with the arc motion, which effectively disperses the pressure on the body. All parts of the patient's body can be evenly supported during the turning process, reducing the pain and discomfort caused by local pressure concentration, and greatly improving the comfort of turning over.

[0012] 2. Improve safety. The knot at the end of the turning cloth is used to fix the center of the turning cloth on the bed, so that the turning cloth will not slide relative to the patient when being pulled by the driving motor, reducing the friction between the turning cloth and the patient's skin, greatly reducing the risk of skin damage, and the arc-shaped movement of the turning cloth is relatively gentle, which can reduce the pressure on the wound, so that the patient's wound is better protected during the turning process, which is conducive to the patient's wound healing and physical recovery; the driving motor can also control the traction speed of the turning cloth, which can better keep the patient's body stable when turning over, reduce the possibility of slipping, and ensure the safety of the patient.

[0013] 3. Improve the convenience of nursing operations. For medical staff, when checking and caring for patients' wounds, they need to have enough space to adjust their body posture and position. However, after the bed board in the prior art is rigidly turned over, its edges and angles may limit the body movements of medical staff, so that when medical staff check the patient's wound, the bed board blocks the medical staff's line of sight or the range of motion of their arms, making it impossible to fully and carefully observe and treat the wound. The turning cloth in the present invention is soft in texture and can fit the patient's body curve closely. When medical staff need to check or treat the wound on the side of the patient's body, the turning cloth can be deformed according to the medical staff's movements, thereby avoiding the medical staff's arms and not blocking the medical staff's line of sight and operating space, so that medical staff can more conveniently approach the wound for detailed observation and treatment.

[0014] Furthermore, the turning cloth is filled with air bags.

[0015] Beneficial effects: The airbag has good elasticity and flexibility, and can be adaptively adjusted according to the patient's body contour and pressure distribution. When the patient lies on the turning cloth, the airbag will provide uniform support to various parts of the body, effectively disperse body pressure, and reduce the risk of pressure sores caused by local pressure concentration. Especially for patients who have been bedridden for a long time, this uniform support can greatly improve their comfort and relieve physical fatigue. In addition, during the turning process, the airbag can play a role in buffering and shock absorption, reducing the impact of the turning action on the patient's body. Compared with the turning method in the prior art, the present invention can make the patient turn over more smoothly and gently, reducing the discomfort and pain caused by the turning action to the patient.

[0016] Furthermore, both end surfaces of the arc-shaped guide rail are provided with slide grooves, and the sliding block is provided with protrusions of corresponding shapes, and the protrusions are located in the slide grooves.

[0017] Beneficial effects: The slide groove can ensure that the slider can only move along the arc path set by the arc guide rail, prevent the slider from offset, shaking or derailment, make the movement of the turning cloth more stable and precise, and ensure that the turning action is carried out according to the preset trajectory. When multiple sliders around the bed body move in coordination, the slide groove can keep each slider in its own accurate position and trajectory, so that the lifting and lowering of the turning cloth around are more synchronized and uniform, so as to better turn the patient over and avoid twisting, uneven pulling of the turning cloth due to inconsistent slider movement.

[0018] Furthermore, a strip-shaped cavity is provided in the middle of the arc-shaped guide rail, the strip-shaped cavity extends into the column, and the rope chain is located in the strip-shaped cavity.

[0019] Beneficial effects: The strip-shaped cavity is used to accommodate the rope chain, preventing the rope chain from being exposed to the outside, and preventing the rope chain from causing scratches, entanglement and other dangers to the surrounding personnel during operation, thereby reducing safety hazards. In addition, there may be various debris, dust, etc. in the ward environment. The exposed rope chain is easily entangled with debris, affecting its normal operation and may even cause failures. The strip-shaped cavity provides a relatively closed space for the rope chain, which can block foreign matter from entering, ensure the smooth movement of the rope chain, and improve the reliability and stability of the equipment.

[0020] Furthermore, a guide wheel is provided on the column, and a ring groove is provided on the guide wheel, and the middle part of the rope chain is wound in the ring groove.

[0021] Beneficial effects: The guide wheel can change the direction of the rope chain so that the pulling force of the driving motor can be reasonably transmitted according to the design requirements, and accurately drive the slider to slide on the arc guide rail along the pre-planned path, thereby effectively lifting the turning cloth and turning the patient over.

[0022] Furthermore, a radially arranged through hole is also provided in the middle of the slider, and the rope chain passes through the through hole and is wound around and fixed on the slider.

[0023] Beneficial effects: The rope chain is passed through the through hole and wrapped around and fixed, which can make the pulling force generated by the driving motor be transmitted to the slider more accurately, effectively reducing the loss and deviation in the process of pulling force transmission, so that the slider can accurately move on the arc guide rail according to the pulling direction and strength of the rope chain, thereby realizing the smooth lifting of the turning cloth and the smooth turning of the patient. When installing or repairing the equipment, the method of passing the rope chain through the through hole and wrapping it around and fixing it is relatively simple, which is convenient for operators to perform installation and disassembly operations.

[0024] Furthermore, a control console is provided on the column, a controller is provided in the control console, and the controller is electrically connected to the driving motor.

[0025] Beneficial effects: The control console serves as the operating hub of the entire turning bed, and the controller is integrated into it, so that medical staff can control the drive motor in a centralized location, greatly improving the convenience of operation; at the same time, the controller in the control console can set a variety of preset turning programs, such as timing the drive motor to work at a certain time interval to drive the slider and the turning cloth to complete the turning action, without the need for medical staff to operate manually frequently, greatly reducing the burden of nursing.

[0033] Embodiment 1

[0034] like Figures 1 to 4 As shown, the intelligent assisted side-turning bed comprises a bed body 1, a cushion 2 located above the bed body 1, a turning cloth 4 located above the cushion 2, and a turning mechanism fixed around the bed body 1.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the turning mechanism includes a column 3 fixed around the bed body 1, an arc-shaped guide rail 11 fixed on the column 3, a slider 10 slidably connected to the arc-shaped guide rail 11, a rope chain 9 fixed on the slider 10, and a driving motor 8 fixed at the other end of the rope chain 9. The driving motor 8 is located at the top of the column 3, the inner arc surface of the arc-shaped guide rail 11 is arranged toward the turning cloth 4, and the slider 10 is fixed on the four corners of the turning cloth 4. The column 3 is also provided with a guide wheel 6, which is located on one side of the driving motor 8. The guide wheel 6 is provided with an annular groove, and the middle part of the rope chain 9 is wound in the annular groove of the guide wheel 6. The guide wheel 6 is used to change the direction of the rope chain 9, so that the pulling force of the driving motor 8 can be reasonably transmitted according to the design requirements, and the slider 10 is accurately driven to slide on the arc-shaped guide rail 11 along the pre-planned path.

[0036] like Figure 1 and Figure 2 As shown, the ends of the turning cloth 4 at both ends are fixed with knots 5, and hooks 12 are provided at both ends of the bed body 1. The knots 5 are fixed on the hooks 12 to fix the middle part of the turning cloth 4 to prevent the turning cloth 4 from moving. Figure 3As shown, the inside of the turning cloth 4 is filled with air bags 401; the air bags 401 have good elasticity and flexibility, and can be adaptively adjusted according to the contour and pressure distribution of the patient's body. When the patient lies on the turning cloth 4, the air bags 401 will provide uniform support to various parts of the body, effectively disperse the body pressure, and reduce the risk of pressure sores caused by local pressure concentration. Especially for patients who have been bedridden for a long time, this uniform support can greatly improve their comfort and relieve physical fatigue. In addition, during the turning process, the air bags 401 can play a role in buffering and shock absorption, reducing the impact of the turning action on the patient's body.

[0037] like Figure 3 and Figure 4 As shown, the two end faces of the arc guide rail 11 are also provided with a slide groove 13, and the slider 10 is provided with a protrusion of a corresponding shape, which is located in the slide groove 13, so that the slider 10 can hold the arc guide rail 11; the slide groove 13 can ensure that the slider 10 can only move along the arc path set by the arc guide rail 11, prevent the slider 10 from being offset, shaking or derailed, make the movement of the turning cloth 4 more stable and accurate, and ensure that the turning action is performed according to the preset trajectory. A strip cavity 14 is provided in the middle of the arc guide rail 11, and the strip cavity 14 extends into the column 3. The rope chain 9 is located in the strip cavity 14. The strip cavity 14 is used to accommodate the rope chain 9 to prevent the rope chain 9 from being exposed to the outside, and to prevent the rope chain 9 from causing scratches, entanglement and other dangers to the surrounding personnel during operation, thereby reducing safety hazards. A radially arranged through hole 101 is also provided in the middle of the slider 10, and the rope chain 9 passes through the through hole 101 and is wound and fixed on the slider 10.

[0038] The column 3 is also provided with a control console 7, in which a PLC controller is provided, and the PLC controller is electrically connected to the drive motor 8. The control console 7 serves as the operation hub of the entire turning bed, allowing medical staff to control the drive motor 8 in a centralized location, greatly improving the convenience of operation.

[0039] The usage of this device is as follows:

[0040] The patient lies on the turning cloth 4, as Figure 5As shown, when turning over is required, the medical staff can control the drive motor 8 to start through the corresponding button on the console 7, thereby pulling the slider 10, and the slider 10 moves upward to drive the turning cloth 4 to lift one side of the patient, thereby assisting the medical staff to turn the patient over. In this process, the design of the arc guide rail 11 can make the traction force of the turning cloth 4 on the patient's body make the movement trajectory of the turning process smoother. Compared with the stiff and direct turning of the bed board in the prior art, the turning cloth 4 in the present invention can fit the body curve, so that the traction force can be evenly distributed on the patient's body, and the patient's body position is gradually changed with the arc movement, which effectively disperses the pressure on the body. During the turning process, all parts of the patient's body can be evenly supported, reducing the pain and discomfort caused by local pressure concentration, and greatly improving the comfort of turning over. In addition, the knot 5 at the end of the turning cloth 4 is used to fix the central part of the turning cloth 4 on the bed body 1, so that the turning cloth 4 will not slide relative to the patient when being pulled by the driving motor 8, thereby reducing the friction between the turning cloth 4 and the patient's skin, greatly reducing the risk of skin damage, and the arc-shaped movement of the turning cloth 4 is relatively gentle, which can reduce the pressure on the wound, so that the patient's wound is better protected during the turning process, which is beneficial to the patient's wound healing and body recovery; the driving motor 8 can also control the traction speed of the turning cloth 4, which can better keep the patient's body stable when turning over, reduce the possibility of slipping, and ensure the patient's safety.

[0041] In addition, for medical staff, when checking and caring for patients' wounds, they need to have enough space to adjust their body posture and position. After the bed board in the prior art is rigidly turned over, its edges and angles may limit the body movements of medical staff, so that when medical staff check patients' wounds, the bed board blocks the medical staff's line of sight or the range of motion of their arms, resulting in the inability to fully and carefully observe and treat the wounds. The turning cloth 4 in the present invention is soft in texture and can fit the patient's body curve closely. When medical staff need to check or treat the wound on the side of the patient's body, the turning cloth 4 can be deformed according to the medical staff's movements, thereby avoiding the medical staff's arms and not blocking the medical staff's line of sight and operating space, so that the medical staff can more conveniently approach the wound for detailed observation and treatment.

[0042] In addition, the PLC controller can set a variety of preset turning programs. For example, at a certain time interval, the drive motor 8 is operated regularly to drive the slider 10 and the turning cloth 4 to complete the turning action. There is no need for medical staff to frequently operate manually, which greatly reduces the nursing burden. At the same time, the equipment can also record the personal information of each burn patient, and conduct big data analysis and comparison through the medical and health cloud platform. For example, the frequency and speed of turning over of patients with similar burn degrees and burn parts can be used for reference and application, so as to formulate the best turning care plan for different patients, further improve the patient's comfort and promote the patient's recovery.

[0043] The above are only embodiments of the present invention. The invention is not limited to the field involved in this implementation case. The common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
