Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically discloses a nursing turning assistance device. Background Technology

[0002] In clinical nursing practice, regular turning is a crucial basic nursing measure for long-term bedridden patients who are unable to turn over independently due to surgery, anesthesia, paralysis, coma, or extreme weakness. Regular turning not only effectively prevents the formation of pressure injuries (commonly known as bedsores), but also promotes blood circulation and reduces the risk of complications such as pulmonary infections and deep vein thrombosis.

[0003] Currently, in clinical nursing practice, turning bedridden patients mainly relies on the assistance of nursing staff or family members. The traditional method typically involves the nurse placing their hands under the patient and using their abdominal and back muscles or shoulders to push the patient to their side or move them. However, this method has the following significant limitations in practical application: For patients who are overweight or completely unable to cooperate, turning them over requires a great deal of physical strength. Nursing staff who perform this kind of high-intensity repetitive physical labor for a long time are very likely to develop muscle strain in the lower back and shoulders, or even occupational diseases such as lumbar disc herniation. During manual turning, if the force is uneven or the coordination is not good, it is easy to drag or twist the patient's skin, generating friction and shearing forces, which increases the risk of skin damage. Patients may experience discomfort, pain, or a lack of security when lying in bed for extended periods. This is especially true for patients who maintain the same posture for long periods, as prolonged pressure on their back muscles and poor blood circulation often lead to muscle stiffness, soreness, and even spasms. Simply turning over is unlikely to effectively relieve this localized discomfort.

[0004] To alleviate the burden on caregivers, some assistive care devices have emerged on the market, such as turning pillows, positioning cushions, and simple turning belts. While these tools can help maintain position to some extent, caregivers still need to exert effort to lift or tilt the patient before placing them in position. Essentially, they don't completely escape the realm of manual lifting and fail to fundamentally address the need for labor-saving and intelligent solutions. A few electric turning beds or nursing beds, although possessing overall turning functions, have complex structures and high costs, making them difficult to popularize in general wards or home care. More importantly, both traditional manual turning methods and existing turning devices have limited functions, primarily focusing on changing position, and lack targeted relief and relaxation functions for the stiffness and soreness in the back muscles caused by continuous pressure on long-term bedridden patients.

[0005] Therefore, developing a nursing turning aid that can help caregivers easily and safely turn patients over, and also help patients relieve back stiffness and discomfort in daily care, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to address the problems existing in the prior art by proposing a nursing turning assist device, comprising a hospital bed, protective components, and two sets of bed frames. A controller is fixedly installed on one side of the bottom of the hospital bed, and a backing plate is fixedly installed on the upper surface of the hospital bed. The two sets of bed frames are respectively fixedly installed on the upper surface of the backing plate. Each set of bed frames is equipped with a turning board inside. The bottom of the backing plate is driven by a symmetrically installed turning mechanism to rotate the corresponding turning board inside the corresponding bed frame to assist the patient in turning over. Each turning board has a storage compartment embedded in its center, and the storage compartment is configured with corresponding internal features. The reciprocating mechanism is connected to a sliding box. A double-section shaft is rotatably inserted inside the lower part of the sliding box. Rocker arms are fixedly sleeved on the outer middle of both ends of the double-section shaft. Massage wheels are installed on the ends of the rocker arms away from the double-section shaft. Concave and convex telescopic parts are provided on both sides of the outer wall of the massage wheels. A driving component is provided inside the upper part of the sliding box. A circulation pipe is embedded inside each of the turning plates. Multiple nozzles are connected and installed inside the upper part of each circulation pipe. Air holes adapted to the air outlets of multiple nozzles are opened on the upper surface of each turning plate. An air pump is connected and installed at one end of the circulation pipe. The air pump is embedded inside one side of the turning plate.

[0007] In the above technical solution, the protective component further includes two sets of lifting guardrails, which are rotatably installed on both sides of the hospital bed.

[0008] In the above technical solution, the turning mechanism further includes a frame beam fixedly installed in the middle of the bottom of the support plate, a frame base fixedly connected to the bottom of the frame beam, and a rotating seat rotatably connected inside the frame base through a rotating hydraulic mechanism. The top of the rotating seat is fixedly installed at the bottom of the turning plate, and a slot for the rotating hydraulic mechanism to move is opened at the bottom of the support plate.

[0009] In the above technical solution, the reciprocating mechanism further includes a lead screw rotatably installed inside the storage compartment, the lead screw being threadedly engaged with the sliding box, the bottom of the sliding box slidingly fitting against the bottom of the inner side of the storage compartment, and two sets of abutments fixedly installed on the outside of one side of the sliding box, the upper ends of the two sets of abutments being in movable contact with the outer wall of one side of the rocker arm.

[0010] In the above technical solution, one end of each of the two lead screws extends to the outside of the bed, and the two lead screws are connected by a common pulley assembly. A rotary motor is fixedly installed on one side of the outside of the bed, and the output end of the rotary motor is connected to the end of one of the lead screws.

[0011] In the above technical solution, the concave-convex telescopic component includes a retaining shell fixedly installed on one side of the outer wall of the massage wheel. A double-headed cylinder is embedded in the middle of the retaining shell. A storage seat is slidably installed inside the retaining shell, both the upper and lower sides. The two ends of the double-headed cylinder are respectively connected to the outer surfaces of the storage seat that are close to each other. Rolling elements are provided on the outer surfaces of the storage seat that are far apart from each other.

[0012] In the above technical solution, the rolling element further includes multiple massage balls, which are equidistantly embedded on the outer surface of one side of the storage card holder along the horizontal direction.

[0013] In the above technical solution, the driving component further includes a dual-axis motor embedded in the upper part of the sliding box. Both ends of the dual-axis motor are fixedly mounted with drive shafts. Both ends of the drive shaft are symmetrically fitted with gear rings. The drive shaft and the gear rings outside the dual-section shaft are meshed and connected. Batteries are installed inside the sliding box and near the bottom of the two sets of rocker arms.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, through the symmetrical installation of a turning mechanism, can independently drive two sets of turning boards to rotate within the bed frame, thereby assisting patients in turning to their sides. This process eliminates the need for nurses to manually lift the patient, significantly reducing the labor intensity of nursing work and effectively preventing occupational injuries such as lumbar muscle strain caused by prolonged high-intensity turning. Simultaneously, the overall rotation of the turning boards ensures even force distribution on the patient's body, avoiding the friction and shearing forces caused by dragging or uneven force during traditional manual turning, thus reducing the risk of skin damage and improving the comfort and safety of turning.

[0015] 2. This invention features a sliding box that moves back and forth along a storage compartment inside the turning panel. Within this sliding box, a rocker arm driven by a dual-axis motor and massage wheels are integrated, enabling automated reciprocating massage of the patient's back while lying flat. The massage wheels contact the patient's back during movement, working in conjunction with the retractable rolling element in the telescopic mechanism to simulate acupressure techniques, achieving deep relaxation of the back muscles. This function effectively alleviates discomfort symptoms such as stiffness and soreness in the back muscles caused by prolonged bed rest, improves local blood circulation, enhances overall patient comfort, and overcomes the shortcomings of traditional turning devices that only change body position and lack relaxation functions. Furthermore, it is convenient to store when not in use, saving space.

[0016] 3. This invention, by embedding a circulation tube and multiple nozzles inside the turning plate and using it in conjunction with an air pump, enables continuous or intermittent ventilation and drying of the patient's back skin while in bed. This design helps keep the back skin dry, reducing skin problems caused by sweat or a damp environment, and further reducing the risk of pressure sores. Simultaneously, this airflow structure operates independently of the massage rollers and can be used in conjunction with the massage function, enhancing the device's therapeutic effect.

[0017] 4. This invention organically integrates turning assistance, massage and soothing functions, and ventilation and drying functions into one unit. The functional modules are rationally arranged and do not interfere with each other. The controller allows for independent or coordinated control of each actuator, making operation simple and highly intelligent. This device is not only compact and relatively low-cost, making it easy to promote and apply in general wards or home care environments, but it also significantly improves the efficiency of nursing work and the patient's bedridden experience, realizing the transformation of nursing devices from single-function to multi-functional and intelligent.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0022] like Figures 1-7 The nursing turning assist device shown includes a hospital bed 1, a protective assembly, and two sets of bed frames 4. A controller 3 is fixedly installed on one side of the bottom of the hospital bed 1, and a backing plate 27 is fixedly installed on the upper surface of the hospital bed 1. The two sets of bed frames 4 are respectively fixedly installed on the upper surface of the backing plate 27. A turning board 5 is provided inside each set of bed frames 4. The bottom of the backing plate 27 is driven by a symmetrically installed turning mechanism to rotate the corresponding turning board 5 inside the corresponding bed frame 4 to assist the patient in turning over. A storage compartment 6 is embedded in the middle of the turning board 5. The storage compartment 6 is connected to a sliding box 13 through a corresponding reciprocating mechanism. Inside the lower part of the 3, a double-section shaft 18 is rotatably inserted. Rocker arms 20 are fixedly sleeved on the outer middle of both ends of the double-section shaft 18. Massage rollers 21 are installed on the ends of the rocker arms 20 away from the double-section shaft 18. The outer walls of the massage rollers 21 are provided with concave and convex telescopic parts on both sides. A drive component is provided inside the upper part of the sliding box 13. A circulation pipe 14 is embedded inside the flipping plate 5. Multiple nozzles 15 are connected and installed inside the upper part of the circulation pipe 14. Air holes adapted to the air outlet of multiple nozzles 15 are opened on the upper surface of the flipping plate 5. An air pump 28 is connected and installed at one end of the circulation pipe 14. The air pump 28 is embedded inside the flipping plate 5 on one side. In this embodiment, the controller 3 is equipped with a PLC controller 3 with a touch panel and a program control module, which is used to regulate the start and stop of electrical control components; When in use, the caregiver uses the controller 3 to enable the turning mechanism to drive the turning board 5 to rotate within the bed frame 4 according to the nursing needs, thereby turning the patient's body to the side. When massage is needed, the drive unit is activated to rotate the double-section shaft 18, making the rocker arm 20 vertical and driving the massage wheel 21 to roll against the patient's back. The concave and convex telescopic parts move synchronously to achieve deep massage. When the ventilation and drying function is turned on, the air pump 28 pressurizes the outside air and sends it into the circulation pipe 14, which is then blown out from the air holes of the turning board 5 through the nozzle 15, directly acting on the patient's back skin. Specifically, the air pump 28 is a miniature silent air pump 28.

[0023] The protective components include two sets of lifting guardrails 2, which are rotatably installed on both sides of the hospital bed 1. In this embodiment, the lifting guardrail 2 adopts a telescopic rotating lifting metal rod structure, which is installed on both sides of the hospital bed 1 through damping rotation, and a positioning buckle is provided at the damping shaft to lock the lifting guardrail 2. When the patient is resting in bed or turning over, the lifting guardrail 2 is pulled up and locked, so that the lifting guardrail 2 is in a protective state, forming a protective barrier around both sides of the hospital bed 1. Conversely, when the patient needs nursing care, changing bedding, or getting out of bed, the lifting guardrail 2 is lowered. The above is the prior art, and will not be described in detail.

[0024] The turning mechanism includes a frame beam 9 fixedly installed in the middle of the bottom of the support plate 27. A frame base 10 is fixedly connected to the bottom of the frame beam 9. A rotating seat 11 is rotatably connected to the inside of the frame base 10 via a rotating hydraulic mechanism 12. The top of the rotating seat 11 is fixedly installed at the bottom of the turning plate 5. A slot for the rotating hydraulic mechanism 12 to move is opened at the bottom of the support plate 27. In this embodiment, the frame 10 is a U-shaped frame, and the inside is rotatably connected to the flipping hydraulic mechanism 12 through the pin shaft. The telescopic end of the flipping hydraulic mechanism 12 is rotatably connected to the rotating seat 11 through the clamp shaft. Under the drive of the flipping hydraulic mechanism 12, the turning board 5 rotates inside the bed frame 4, so that the patient's body rotates as a whole with the turning board 5, and the force is evenly distributed. This avoids the skin friction caused by dragging during traditional manual turning and reduces the risk of skin damage. The two turning mechanisms are independently controlled, allowing the patient to turn to the left or right.

[0025] The reciprocating mechanism includes a lead screw 29 rotatably installed inside the storage compartment 6. The lead screw 29 is threadedly engaged with the sliding box 13. The bottom of the sliding box 13 slides against the bottom of the inner side of the storage compartment 6. Two sets of abutment rods 16 are fixedly installed on the outside of one side of the sliding box 13. The upper ends of the two sets of abutment rods 16 are in movable contact with the outer wall of one side of the rocker arm 20. One end of each of the two lead screws 29 extends to the outside of the bed 1, and the two lead screws 29 are connected to each other through a common pulley assembly 8. A rotary motor 7 is fixedly installed on the outside of the bed 1. The output end of the rotary motor 7 is connected to the end of one of the lead screws 29. In this embodiment, after the rotary motor 7 is started, it drives the lead screw 29 connected to it to rotate. The lead screw 29 drives another lead screw 29 to rotate at the same speed and in the same direction through the synchronous transmission of the pulley assembly 8. The two lead screws 29 rotate synchronously in the forward or reverse direction, driving the two sliding boxes 13 to perform reciprocating linear motion synchronously in their respective storage compartments 6. The sliding boxes 13 drive the massage rollers 21 inside to move synchronously, realizing massage of different positions on the patient's back.

[0026] The driving component includes a dual-axis motor 19 embedded in the upper part of the sliding box 13. Both ends of the dual-axis motor 19 are fixedly mounted with drive shafts 17. Both ends of the drive shaft 17 are symmetrically fitted with gear rings 30. The drive shaft 17 and the gear rings 30 on the outside of the double-section shaft 18 are meshed and connected. Batteries 23 are installed inside the sliding box 13 and near the bottom of the two sets of rocker arms 20. In this embodiment, the dual-axis motor 19 adopts a worm gear reduction structure, which has a self-locking function, large output torque, and low operating noise. The two output ends of the dual-axis motor 19 drive the drive shaft 17 to rotate synchronously. The drive shaft 17 transmits power to the double-section shaft 18 through the meshing transmission of the gear ring 30, causing the double-section shaft 18 to rotate. The double-section shaft 18 then drives the rocker arms 20 at both ends to swing in a circular motion. When the rocker arms 20 extend from the storage compartment 6 and rotate into a vertical position, the massage roller 21 can fit against the patient's back for rolling massage. The meshing transmission of the gear ring 30 realizes the precise transmission of power. The self-locking function of the worm gear reduction motor allows the rocker arms 20 to stop at any angle, realizing the fixed-point locking of the massage position. Specifically, battery 23 can power the internal electrical components inside sliding box 13.

[0027] The concave-convex telescopic component includes a retaining shell 22 fixedly installed on one side of the outer wall of the massage roller 21. A double-headed cylinder 25 is embedded in the middle of the retaining shell 22. A storage seat 26 is slidably installed inside the retaining shell 22, both above and below. The two ends of the double-headed cylinder 25 are respectively connected to the outer surface of the storage seat 26 on the side that is close to each other. Rolling elements are provided on the outer surface of the storage seat 26 on the side that is far apart from each other. The rolling elements include multiple massage balls 24. The multiple massage balls 24 are embedded at equal distances along the horizontal direction on one side of the outer surface of the storage seat 26. In this embodiment, during the operation of the massage roller 21, the storage holder 26 driven by the double-headed cylinder 25 can freely extend and retract the massage ball 24, enabling the massage roller 21 to have a concave-convex massage function, simulating the massage technique of manual acupressure, and precisely soothing the acupoints and deep muscles of the back. Compared with the fixed and unadjustable massage protrusions in the prior art, the massage depth can be adjusted according to the patient's needs, improving the targeting and effect of the massage. The enclosed structure of the retainer 22 protects the internal double-headed cylinder 25 and storage holder 26, preventing damage caused by external impact during the massage and extending the service life of the mechanism. The sliding installation of the storage holder 26 ensures the smoothness of the extension and retraction movements without any jamming or sticking. Specifically, the surface of the storage holder 26 has a spherical groove, which allows the massage ball 24 to roll freely inside. When it moves with the sliding box 13, the rolling of the massage ball 24 covers the patient's entire back. The rolling contact also reduces friction between the massage ball and the patient, improving the comfort of the massage.

[0028] Working principle: When using this device, medical staff or patients' family members can independently or collaboratively control each actuator through controller 3 to achieve multiple nursing functions such as turning assistance, back massage and ventilation drying; When it is necessary to assist the patient in turning over, the turning mechanism is activated via controller 3. The hydraulic mechanism 12 begins to extend and retract, and its extension end pushes the rotating seat 11. Since the top of the rotating seat 11 is fixedly connected to the bottom of the turning plate 5, and the bottom of the abutment 27 has a slot for the hydraulic mechanism 12 to move, the turning plate 5 can rotate smoothly around its axis within the bed frame 4. The two sets of turning mechanisms are symmetrically installed, and can drive the corresponding turning plate 5 to independently perform left or right turning operations, thereby assisting the patient to lie on their side or change position. During this process, the lifting guardrail 2 is raised to prevent the patient from accidentally falling out of bed and ensure safety. This turning method does not require caregivers to manually lift the patient, significantly reducing labor intensity, and at the same time avoiding friction and shearing force on the patient's skin caused by uneven force. When a massage is needed to relieve muscle stiffness in the patient's back, the rotary motor 7 is activated. The rotary motor 7 drives two lead screws 29 to rotate synchronously via a pulley assembly 8. The lead screws 29 are threaded into the sliding box 13, causing the sliding box 13 to slide back and forth along the bottom inner side of the storage compartment 6. Simultaneously, the dual-axis motor 19 located above the sliding box 13 is activated. The drive shafts 17 at both ends of the dual-axis motor 19 engage with the gear rings 30 on the outside of the double-section shaft 18 via gear rings 30, causing the double-section shaft 18 to rotate. As the double-section shaft 18 rotates, the rocker arms 20, fixedly sleeved at both ends, swing accordingly, keeping the rocker arms 20 and the massage rollers 21 at a vertical angle, thus applying pressure to the patient's back. As the sliding box 13 reciprocates, the massage rollers 21 roll back and forth on the patient's back, achieving a large-area massage. The concave and convex telescopic parts on both sides of the outer wall of the massage roller 21 can further adjust the massage intensity. The double-headed cylinder 25 pushes the storage card seat 26 to slide in the card case 22 according to the telescopic needs, so that multiple massage balls 24 embedded on one side of the outer surface of the storage card seat 26 protrude from the surface of the massage roller 21, thereby enhancing the massage effect, simulating acupressure techniques, and deeply soothing the back muscles. The telescopic length of the double-headed cylinder 25 can be adjusted according to the fit of the patient's back, thereby meeting the usage needs of different patients. During operation, the battery 23 provides power to each electric component.

[0029] When a patient is bedridden for an extended period of time, the air pump 28 is activated. The air pump 28 delivers air to the circulation pipe 14 embedded inside the turning board 5. The air is then sprayed out through multiple nozzles 15 and blown evenly onto the patient's back through the corresponding air holes on the upper surface of the turning board 5, achieving continuous or intermittent ventilation and drying, and further improving nursing comfort.

[0030] Through the coordinated control of controller 3, the functions of turning over, massage and ventilation can be flexibly combined according to the actual needs of the patient to achieve intelligent care, effectively reduce the burden on nursing staff and improve the patient's bed rest experience.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
