Technical Field

[0001] This invention relates to the technical field of nursing equipment, specifically to a comprehensive medical nursing device. Background Technology

[0002] In healthcare, wheelchairs are common assistive devices used to help patients with limited mobility move around. However, traditional wheelchairs are limited in function, providing only basic mobility support and failing to meet the comprehensive care needs of patients. Patients who use wheelchairs for extended periods are prone to problems such as poor blood circulation in the lower limbs and muscle atrophy, requiring additional massage and care. Furthermore, when used outdoors, they lack effective sun and rain protection, affecting comfort. While some existing wheelchairs integrate care functions, they are often structurally complex, inconvenient to operate, and lack coordination between functions, resulting in low efficiency. Therefore, there is an urgent need for a comprehensive device capable of automatic movement and providing lower limb care, foot care, and shelter through mechanical linkages to improve care efficiency and patient experience. Summary of the Invention

[0003] The purpose of this application is to provide a comprehensive medical care device that organically combines automatic walking, lower limb care, foot care, and shielding functions through mechanical linkage design, thereby achieving efficient and automated nursing services.

[0004] Therefore, the technical solution adopted in this application is as follows: a comprehensive medical care device, including a wheelchair body, an automatic walking mechanism provided at the lower part of the wheelchair body, a lower limb care mechanism driven and connected to a lower limb care mechanism through a linkage mechanism, a foot care mechanism connected to a foot care mechanism through a linkage mechanism, and a shielding mechanism provided at the upper part of the wheelchair body, the shielding mechanism being driven and connected to the automatic walking mechanism through a cooperative mechanism.

[0005] By adopting the above technical solution: the automatic walking mechanism of this application serves as the power source to drive the wheelchair; simultaneously, the walking power is transmitted to the lower limb care mechanism through a linkage mechanism to care for the patient's legs; the movement of the lower limb care mechanism, in turn, drives the foot care mechanism through a linkage mechanism to care for the feet; the shielding mechanism is linked with the automatic walking mechanism through a coordination mechanism, and the degree of shielding can be manually adjusted as needed to adapt to environmental changes. This invention achieves automated linkage between walking and care functions, eliminating the need for additional power sources, thus reducing energy consumption and operational complexity. While the patient is using the wheelchair, the lower limbs and feet are automatically massaged, promoting blood circulation and preventing muscle atrophy; the shielding mechanism provides a comfortable outdoor environment, improving overall care efficiency and patient comfort.

[0006] Preferably, the wheelchair body includes a seat, a backrest located on the rear side of the seat, a front frame located on the front side of the seat, a lower limb care mechanism located on the front frame, a foot care mechanism located on the lower part of the front frame, a shielding mechanism located on the upper side of the backrest, and an automatic walking mechanism including a support frame connected to the seat, two large electric walking wheels connected to the lower part of the support frame, a pivot connecting the two large electric walking wheels, and two small walking wheels located on the lower part of the front frame.

[0007] By adopting the above technical solution: the large electric wheels are driven by a motor, and a power source can be installed at the rear of the wheelchair to supply power to the motor, which rotates synchronously through a shaft to provide the main power for movement; the smaller wheels are driven wheels, assisting in steering and stability. The wheelchair body adopts a modular design, with reasonable installation positions for each mechanism, facilitating overall coordination; the large electric wheels ensure smooth movement, while the smaller wheels enhance turning flexibility and stability, making it suitable for various indoor and outdoor environments.

[0008] Preferably, the lower limb care mechanism includes a leg cover plate hinged to the front frame at its upper end, the inner side of the leg cover plate is provided with massage protrusions, and the lower side of the leg cover plate is drivenly connected to a linkage mechanism.

[0009] By adopting the above technical solution: the leg cover plate swings around the hinge point under the drive of the linkage mechanism, so that the massage protrusions on the inside repeatedly press and massage the patient's leg. Through mechanical automatic massage, the leg muscles and acupoints are stimulated, blood circulation is promoted, numbness and swelling of the lower limbs are relieved, and deep vein thrombosis is prevented.

[0010] Preferably, the linkage mechanism includes a transmission cylinder mounted on the front frame, a linkage rod passing through the transmission cylinder, a driven block on the inner side of the leg cover, a sliding groove in the driven block, a push shaft slidingly mounted in the sliding groove, one end of the linkage rod being hinged to the push shaft, and the other end passing through the transmission cylinder and being mounted on a push plate, a spring being provided between the linkage rod and the transmission cylinder, and a cam on the rotating shaft contacting the push plate.

[0011] By adopting the above technical solution: when the electric walking wheel rotates, the cam on the rotating shaft moves accordingly, periodically pushing the push plate, causing the linkage rod to move back and forth in the transmission cylinder; the linkage rod drives the leg cover plate to swing through the push shaft and the driven block; the spring is used for reset to ensure smooth swing; the rotational power of the electric walking wheel is converted into the reciprocating motion of the leg care mechanism to achieve automatic massage without additional control, which is energy-saving and efficient; the spring buffer ensures gentle movement and avoids causing discomfort to the patient.

[0012] Preferably, the foot care mechanism includes a pedal disposed on the lower side of the front frame, and a plurality of massage rollers are rotatably connected to the pedal, and the plurality of massage rollers are drivenly connected to a linkage mechanism.

[0013] By adopting the above technical solution: the patient's feet are placed on the pedal, and the massage roller rotates under the drive of the linkage mechanism to perform rolling massage on the soles of the feet, stimulate acupoints and nerves on the soles of the feet, promote blood circulation throughout the body, relieve fatigue, and at the same time, in conjunction with lower limb care, enhance the overall care effect.

[0014] Preferably, the linkage mechanism includes a rack that is movably mounted on the side wall of the pedal via a limiting groove, and the shaft ends of the plurality of massage rollers are provided with gears. The rack meshes with the plurality of gears, and the inner end of the rack is provided with a groove plate. The lower end of the leg cover is provided with a drive rod, and the drive rod is slidably mounted in the groove plate.

[0015] By adopting the above technical solution: when the leg cover swings, the drive rod at its lower end slides in the groove plate, pushing the rack to move along the limiting groove; the rack meshes with the gears of each massage roller, driving the massage roller to rotate synchronously, directly transmitting the movement of the lower limb care mechanism to the foot care mechanism, realizing linkage, eliminating the need for a separate power source, simplifying the structure, and improving energy utilization efficiency.

[0016] Preferably, the shielding mechanism includes a roll box located at the top of the backrest, in which a shielding cloth is wound up via a torsion shaft. The end of the shielding cloth is provided with a sliding shaft, and both ends of the sliding shaft slide within a sliding frame located on the backrest. The sliding shaft is drivenly connected to a cooperating mechanism.

[0017] By adopting the above technical solution: the tarpaulin is naturally rolled up in the roll box by the torque of the torsion shaft; when the cooperating mechanism pulls the sliding shaft, the tarpaulin unfolds along the sliding frame to form a shield; when the cooperating mechanism is released, the torsion shaft automatically rolls up the tarpaulin, providing adjustable sunshade or rain protection functions, improving the outdoor user experience, and the roll-up design saves space and is easy to use.

[0018] Preferably, the coordinating mechanism includes a pull rope connected to the sliding shaft, guide groove wheels rotatably connected to the end of the sliding frame and the top of the backrest, the pull rope being connected to the pulling assembly after passing through the two guide groove wheels, and a locking assembly for locking the pulling assembly.

[0019] By adopting the above technical solution: the pull component operates the pull rope, which changes direction via the guide groove wheel, pulling the sliding shaft to move, thereby controlling the unfolding and retraction of the covering cloth; the locking component is used to fix the position of the covering cloth, realizing manual or automatic control of the covering mechanism; the guide groove wheel reduces friction and makes operation easier; the locking component ensures that the covering cloth remains stable when needed.

[0020] Preferably, the pulling assembly includes an active grooved wheel rotatably disposed at the lower end of the backrest, the end of the pull rope being fixed to the active grooved wheel, and a handle rod, one end of which is rotatably connected to the backrest, the active grooved wheel being rotatably disposed on the handle rod, and a limiting corner block being provided between the other end of the handle rod and the handle on the upper side of the seat.

[0021] By adopting the above technical solution: rotating the handle lever drives the active grooved wheel to move and contact the electric walking wheel. When the electric walking wheel rotates, it causes the active grooved wheel to rotate. The degree of unfolding of the drape can be controlled by pulling the rope. When it is fully unfolded, the handle lever is released and reset. The limiting corner block is used to fix the position of the handle lever to prevent accidental movement. The manual operation is simple and intuitive, and patients or caregivers can easily adjust the coverage area. The limiting corner block improves safety and prevents the drape from retracting.

[0022] Preferably, the locking assembly includes a positioning groove on the side of the backrest, a pin slidably connected to the positioning groove via a compression spring, one end of a pull cable connected to the pin, a squeeze brake hinged to the handle rod, the other end of the pull cable being connected to the squeeze brake via a positioning tube, and a ratchet disposed outside the drive groove wheel and cooperating with the pin.

[0023] By adopting the above technical solution: when rotating the handle lever, the brake is first squeezed downwards. When the brake is squeezed, the pin is pulled by the pull cable to overcome the spring force and disengage from the ratchet, allowing the drive groove wheel to rotate freely. After releasing the brake, the spring pushes the pin to engage with the ratchet, locking the drive groove wheel. This provides a reliable locking mechanism to prevent the tarpaulin from being accidentally retracted under wind or vibration, ensuring the stability of the tarpaulin. It is easy to operate and can be controlled with just one hand.

[0024] The working principle and beneficial effects of this application are as follows: 1. This application uses an automatic walking mechanism as a power source to drive the wheelchair; simultaneously, a linkage mechanism transmits the walking power to the lower limb care mechanism to care for the patient's legs; the movement of the lower limb care mechanism, in turn, drives the foot care mechanism through a linkage mechanism to care for the feet; the shielding mechanism is linked to the automatic walking mechanism through a coordination mechanism, and the degree of shielding can be manually adjusted as needed to adapt to environmental changes. This invention achieves automated linkage between walking and care functions, eliminating the need for additional power sources, reducing energy consumption and operational complexity. While the patient is using the wheelchair, the lower limbs and feet are automatically massaged, promoting blood circulation and preventing muscle atrophy; the shielding mechanism provides a comfortable outdoor environment, improving overall care efficiency and patient comfort.

[0025] 2. When the electric walking wheel rotates, the cam on the rotating shaft moves accordingly, periodically pushing the push plate, causing the linkage rod to reciprocate within the transmission cylinder; the linkage rod drives the leg cover plate to swing through the push shaft and the driven block; the spring is used for reset to ensure smooth swing; the rotational power of the electric walking wheel is converted into the reciprocating motion of the leg care mechanism, realizing automatic massage without additional control, and is energy-efficient; the spring buffer ensures gentle movement and avoids causing discomfort to the patient.

[0026] 3. Rotating the handle lever moves the active grooved wheel to contact the electric walking wheel. When the electric walking wheel rotates, it causes the active grooved wheel to rotate. The degree of unfolding of the drape can be controlled by pulling the rope. When it is fully unfolded, release the handle lever, and the handle lever will return to its original position. The limiting corner block is used to fix the position of the handle lever to prevent accidental movement. The manual operation is simple and intuitive, and patients or caregivers can easily adjust the coverage area. The limiting corner block improves safety and prevents the drape from retracting.

[0034] The electric large wheels 220 are driven by a motor. A power source can be installed at the rear of the wheelchair to supply power to the motor, which rotates synchronously via a pivot 230, providing the main power for movement. The smaller wheels 240 are driven wheels, assisting in steering and stability. The wheelchair body 100 adopts a modular design, with each mechanism installed in a reasonable position for easy overall coordination. The electric large wheels 220 ensure smooth movement, while the smaller wheels 240 enhance turning flexibility and stability, making it suitable for various indoor and outdoor environments.

[0035] Reference Figure 1 and Figure 2 In this embodiment, the lower limb care mechanism 400 includes a leg cover plate 410 hinged at its upper end to the front frame 130. The inner side of the leg cover plate 410 is provided with massage protrusions, and the lower side of the leg cover plate 410 is driven to be connected to the linkage mechanism 300. The leg cover plate 410 swings around the hinge point under the drive of the linkage mechanism 300, so that the massage protrusions on the inner side repeatedly press and massage the patient's leg. Through mechanical automatic massage, the leg muscles and acupoints are stimulated, blood circulation is promoted, numbness and swelling of the lower limbs are relieved, and deep vein thrombosis is prevented.

[0036] Reference Figure 2 In this embodiment, the linkage mechanism 300 includes a transmission cylinder 310 mounted on the front frame 130. A linkage rod 320 passes through the transmission cylinder 310. A driven block 330 is provided on the inner side of the leg cover plate 410. A sliding groove 340 is provided in the driven block 330. A push shaft 350 is slidably mounted in the sliding groove 340. One end of the linkage rod 320 is hinged to the push shaft 350, and the other end passes through the transmission cylinder 310 and is provided with a push plate 360. A spring 370 is provided between the linkage rod 320 and the transmission cylinder 310. A cam 380 is provided on the rotating shaft 230 that contacts the push plate 360.

[0037] When the electric walking wheel 220 rotates, the cam 380 on the rotating shaft 230 moves accordingly, periodically pushing the push plate 360, causing the linkage rod 320 to reciprocate within the transmission cylinder 310; the linkage rod 320 drives the leg cover plate 410 to swing through the push shaft 350 and the driven block 330; the spring 370 is used for reset to ensure smooth swinging; the rotational power of the electric walking wheel 220 is converted into the reciprocating motion of the leg care mechanism to achieve automatic massage without additional control, which is energy-saving and efficient; the spring 370 buffers the movement to ensure gentleness and avoid discomfort to the patient.

[0038] Reference Figure 1 and Figure 3 In this embodiment, the foot care mechanism 600 includes a pedal 610 disposed on the lower side of the front frame 130. A plurality of massage rollers 620 are rotatably connected to the pedal 610, and all of the massage rollers 620 are driven and connected to a linkage mechanism 500. When the patient's foot is placed on the pedal 610, the massage rollers 620 rotate under the drive of the linkage mechanism 500, providing rolling massage to the sole of the foot, stimulating acupoints and nerves, promoting blood circulation throughout the body, relieving fatigue, and simultaneously enhancing the overall care effect in conjunction with lower limb care.

[0039] Reference Figure 3 and Figure 4 In this embodiment, the linkage mechanism 500 includes a rack 520 movably mounted on the side wall of the pedal 610 via a limiting slide groove 510. The shaft ends of the multiple massage rollers 620 are provided with gears 530. The rack 520 meshes with the multiple gears 530. The inner end of the rack 520 is provided with a groove plate 540. The lower end of the leg cover plate 410 is provided with a drive rod 550, which is slidably mounted in the groove plate 540.

[0040] When the leg cover 410 swings, the drive rod 550 at its lower end slides in the groove plate 540, pushing the rack 520 to move along the limiting groove; the rack 520 meshes with the gears 530 of each massage roller 620, driving the massage rollers 620 to rotate synchronously, directly transmitting the movement of the lower limb care mechanism 400 to the foot care mechanism 600, realizing linkage, eliminating the need for a separate power source, simplifying the structure and improving energy utilization efficiency.

[0041] Reference Figure 1 and Figure 5 In this embodiment, the shielding mechanism 700 includes a roll box 710 disposed at the top of the backrest 120. A shielding cloth is wound inside the roll box 710 via a torsion shaft 720. The end of the shielding cloth is provided with a sliding shaft 730. The two ends of the sliding shaft 730 slide within a sliding frame 740 disposed on the backrest 120. The sliding shaft 730 is drivenly connected to the cooperating mechanism 800. The shielding cloth is naturally wound into the roll box 710 by the torque of the torsion shaft 720. When the cooperating mechanism 800 pulls the sliding shaft 730, the shielding cloth unfolds along the sliding frame 740 to form a shielding cover. When the cooperating mechanism 800 is released, the torsion shaft 720 automatically winds up the shielding cloth, providing adjustable sunshade or rain protection functions, improving the outdoor user experience, and the winding design saves space and is convenient to use.

[0042] Reference Figure 5 The cooperating mechanism 800 in this embodiment includes a pull rope 810 connected to the sliding shaft 730. Guide rollers 820 are rotatably connected to the end of the sliding frame 740 and the top of the backrest 120. The pull rope 810 passes around the two guide rollers 820 and is connected to the pulling assembly. It also includes a locking assembly to lock the pulling assembly. The pull rope 810 is operated by the pulling assembly, and the pull rope 810 changes direction via the guide rollers 820, pulling the sliding shaft 730 to move, thereby controlling the unfolding and retraction of the covering cloth. The locking assembly is used to fix the position of the covering cloth, realizing manual or automatic control of the covering mechanism 700. The guide rollers 820 reduce friction and make operation easier. The locking assembly ensures that the covering cloth remains stable when needed.

[0043] The pulling assembly in this embodiment includes an active grooved wheel 830 rotatably disposed at the lower end of the backrest 120, the end of the pull rope 810 being fixed on the active grooved wheel 830, and a handle 840. One end of the handle 840 is rotatably connected to the backrest 120, the active grooved wheel 830 is rotatably disposed on the handle 840, and a limiting corner block 851 is provided between the other end of the handle 840 and the handle 850 on the upper side of the seat 110.

[0044] Rotating the handle lever 840 causes the active grooved wheel 830 to move and contact the electric walking wheel 220. When the electric walking wheel 220 rotates, it causes the active grooved wheel 830 to rotate. The degree of unfolding of the drape is controlled by the pull rope 810. When it is fully unfolded, the handle lever 840 is released and returns to its original position. The limiting corner block 851 is used to fix the position of the handle lever 840 to prevent accidental movement. The manual operation is simple and intuitive, and patients or caregivers can easily adjust the coverage area. The limiting corner block 851 improves safety and prevents the drape from retracting.

[0045] The locking assembly in this embodiment includes a positioning groove 861 disposed on the side of the backrest 120. A pin 863 is slidably connected to the positioning groove 861 via a compression spring 862. One end of a pull wire 864 is connected to the pin 863. A squeeze brake 865 is hinged to the handle rod 840. The other end of the pull wire 864 is connected to the squeeze brake 865 via a positioning tube 866. The assembly also includes a ratchet 867 disposed on the outside of the drive groove wheel 830 and cooperating with the pin 863.

[0046] When rotating the handle lever 840, first squeeze the brake 865 downwards. When the brake 865 is squeezed, the pull cable 864 pulls the pin 863 to overcome the force of the spring 862, disengaging it from the ratchet 867 and allowing the drive gear 830 to rotate freely. After releasing the brake 865, the spring 862 pushes the pin 863 to engage with the ratchet 867, locking the drive gear 830. This provides a reliable locking mechanism to prevent the tarpaulin from accidentally retracting under wind or vibration, ensuring the stability of the tarpaulin. It is easy to operate and can be controlled with just one hand.
