Description

Technical Field

[0001] This invention relates to the field of integrated rehabilitation training and nursing devices, specifically an integrated rehabilitation training and nursing device for cardiovascular medicine. Background Technology

[0002] With the rapid development of modern medical care and cardiovascular rehabilitation medicine, lower limb functional rehabilitation and automated physiological care for long-term bedridden or postoperative cardiovascular disease patients have become a key focus of clinical attention. Cardiovascular disease patients often face risks such as poor lower limb blood circulation, muscle atrophy, and deep vein thrombosis in the lower limbs, necessitating the development of integrated intelligent equipment that combines passive lower limb rehabilitation exercises, dynamic postural fine-tuning, and hydrotherapy massage. This efficient and safe integrated lower limb rehabilitation and nursing device not only significantly reduces the workload of medical staff but also promotes venous return and prevents thrombosis through lower limb joint flexion-extension and contraction training. It has extremely broad application prospects and significant clinical value in medical rehabilitation, elderly care, and clinical cardiovascular medicine.

[0003] In traditional cardiovascular lower limb care and rehabilitation equipment, independent horizontal exercise training frames or manual passive flexion and extension of lower limb joints are usually used. The fixation of the affected limb mainly relies on traditional rigid straps or fixation plates for rigid restraint, or on manual swinging assisted by medical staff.

[0004] However, existing nursing rehabilitation devices have the following problems in actual clinical use: First, the foot fixation lacks flexible cushioning and an emergency quick-release mechanism. Traditional rigid straps are prone to causing pressure damage to the patient's fragile lower limb skin, and cannot achieve quick unlocking and automatic mechanical ejection in case of emergency or at the end of care. The operation is cumbersome and poses safety hazards. Second, rehabilitation exercises are disconnected from water massage. There is a lack of synchronous linkage between lower limb opening and closing, popliteal flexion and extension and water washing. Third, trunk protection lacks an adaptive pack. Patients are prone to postural deviation or local pressure during passive lower limb exercise training, making it difficult to achieve a comfortable, safe and efficient integrated nursing effect. Therefore, those skilled in the art provide an integrated device for cardiovascular rehabilitation training and nursing to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated device for cardiovascular rehabilitation training and nursing, in order to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The integrated nursing device includes a foot fixing mechanism, a leg opening mechanism, a water circulation mechanism, a popliteal fossa bending mechanism, a drive mechanism, and a housing mechanism. The foot fixing mechanism and the leg opening mechanism are engaged, the water circulation mechanism and the housing mechanism are connected, the popliteal fossa bending mechanism and the housing mechanism are slidably connected, the drive mechanism and the popliteal fossa bending mechanism are driven, the drive mechanism and the water circulation mechanism are driven, the drive mechanism and the housing mechanism are fastened, the drive mechanism and the leg opening mechanism are driven, and the leg opening mechanism and the housing mechanism are slidably connected.

[0008] By adopting the above technical solution, the box mechanism serves as the main support and protection body of the entire device. The water circulation mechanism is connected to the box mechanism to realize the flow and circulation of bathing and rinsing liquids. The patient's body is placed inside the box mechanism. The foot fixing mechanism and the leg opening mechanism are engaged to restrain and position the patient's feet and lower limbs. The drive mechanism is firmly installed on the box mechanism and is connected to the leg opening mechanism, the popliteal flexion mechanism, and the water circulation mechanism respectively. The leg opening mechanism is driven to slide on the box mechanism to realize the lateral opening and closing movement of the legs. At the same time, the popliteal flexion mechanism is driven to slide on the box mechanism to drive the patient's knee and popliteal flexion and extension to flex and lift. It also works in conjunction with the water circulation mechanism to perform medicated bath or water rinsing and massage. The efficient linkage and cooperation of each mechanism achieves the effects of adaptive fixation of the lower limbs of bedridden patients, rehabilitation care of leg opening and closing and popliteal flexion and extension, water washing and cleaning, and massage.

[0009] Furthermore, the housing mechanism includes a top cover, a nursing tank, and a body fixing component. The top cover and the nursing tank are hinged together, the body fixing component is fastened to the top cover, the drive mechanism is fastened to the nursing tank, the leg opening mechanism and the popliteal fossa bending mechanism are both slidably connected to the nursing tank, and the water circulation mechanism is connected to the nursing tank.

[0010] By adopting the above technical solution, the nursing tank forms a closed and bathing cavity that supports the patient's lower limbs and torso. The upper cover is hinged to the nursing tank so that it can be opened or closed for sealing. The body fixation component is fastened to the inside of the upper cover, and when the upper cover is fastened, it applies a stable and flexible limiting fixation to the patient's upper torso. The drive mechanism is fastened to the nursing tank and drives the leg opening mechanism and the popliteal flexion mechanism, which are slidably connected to the nursing tank, to perform translation and flexion and extension movements along the tank. The water circulation mechanism is connected to the nursing tank to realize the injection and circulation of nursing fluid and the rinsing and massage effects. All components work together to realize the rapid construction of a safe nursing space, stable protection of the body, and guidance of nursing movements.

[0011] Furthermore, the body fixation component includes an integrated suction air pump and an elastic airbag. The integrated suction air pump is securely connected to the care tank, the elastic airbag is securely connected to the top cover, and the integrated suction air pump and the elastic airbag are connected.

[0012] By adopting the above technical solution, the integrated suction and aspiration air pump is securely installed on the nursing tank and connected to the elastic airbag secured to the inner wall of the cover through an air passage. When the patient lies in the tank and the cover is fastened, the integrated suction and aspiration air pump starts to inflate, causing the elastic airbag to expand rapidly and flexibly conform to the patient's body surface, achieving individualized and stable wrapping and protection without pressure pain. When the nursing care is completed or when it is necessary to open the cover, the integrated suction and aspiration air pump reverses to perform air extraction, causing the elastic airbag to quickly deflate and contract to release the patient's body, achieving the beneficial effects of flexible anti-pressure injury, adaptive fit, and rapid detachment and closure during the body fixation process.

[0013] Furthermore, the leg-opening mechanism includes an extension block, a spacing screw, a spacing slide bar, a spacing motor, a spacing block, a foot abutment block, a foot abutment elastic element, and a pop-out assembly. The spacing motor and the spacing screw are driven together; the spacing screw and the spacing block are driven together; the spacing block and the extension block are slidably connected; the drive mechanism and the extension block are driven together; the extension block and the nursing tank are slidably connected; the spacing block and the spacing slide bar are slidably connected; the foot abutment block and the spacing block are slidably connected; the foot abutment elastic element and the spacing block are fastened together; the foot abutment elastic element and the foot abutment block are fastened together; the foot fixing mechanism and the foot abutment block are engaged; the spacing block has a locking groove; the foot fixing mechanism and the locking groove are slidably connected; and the pop-out assembly abuts against the foot fixing mechanism.

[0014] By adopting the above technical solution, the drive mechanism drives the extension block to slide back and forth along the nursing groove to achieve leg extension and flexion adjustment. The spacing motor starts and drives the spacing screw to rotate. Through the threaded transmission, the spacing block slides along the spacing slide rod and the extension block to adjust the lateral extension spacing of the two legs on both sides. The foot fixing mechanism slides into the locking groove provided on the spacing block and locks with the foot abutment block. The two ends of the foot abutment elastic element are respectively fastened to the spacing block and the foot abutment block, providing buffer and flexible clamping force when clamping the foot. When the nursing is completed and it needs to be removed, the pop-out component is controlled to abut and drive the foot fixing mechanism and trigger to release the locking, so that the foot fixing mechanism pops out smoothly from the locking groove. This realizes the electric adjustment of the leg spacing, the flexible and elastic clamping of the foot, and the rapid pop-out and removal of the foot fixing mechanism.

[0015] Furthermore, the pop-out assembly includes a pop-out block, a pop-out elastic element, a push-out elastic element, a first pop-out rod, and a second pop-out rod. An even number of foot abutment blocks are provided, with every two foot abutment blocks located on either side of the locking groove. Two pop-out blocks are provided, each located on either side of the extension block. The pop-out block and the extension block are fastened together. The first pop-out rod is hinged to the spacing block. The first pop-out rod is fastened to the pop-out elastic element. The pop-out elastic element is fastened to the spacing block. The pop-out block and the first pop-out rod are driven together. The first pop-out rod is driven together to the foot abutment block. The pop-out block and the second pop-out rod are driven together. The second pop-out rod and the foot abutment block are fastened together. The push-out elastic element abuts against the foot fixing mechanism. The push-out elastic element is fastened to the spacing block.

[0016] By adopting the above technical solution, an even number of foot abutment blocks are symmetrically arranged on both sides of the locking groove. When the extension block moves to the disengagement position, the two pop-out blocks fastened to both sides of the extension block respectively engage with the first pop-out rod and the second pop-out rod hinged on the spacing block. This drives the first pop-out rod to swing against the tension of the pop-out elastic element, causing the foot abutment block connected to it to open outward and release the locking. At the same time, the second pop-out rod is pushed by the pop-out block and moves out in conjunction with the foot abutment block fastened to it. The push-out elastic element, which was originally in a compressed and energy-storing state and fastened to the spacing block, releases its elastic force, directly abuts against and forcefully pushes the foot fixing mechanism out of the locking groove, thus realizing the linkage unlocking of the foot fixing state and the automatic mechanical push-out discharge.

[0017] Furthermore, the foot fixing mechanism includes a foot block, a fixing elastic element, a foot instep block, an ankle block, a tensioning block, and a quick-release assembly. The foot block is slidably connected to the locking groove, the foot block is engaged with the foot abutment block, the foot block abuts against the ejection elastic element, the fixing elastic element is sleeved with the foot block, the fixing elastic element is sleeved with the foot instep block, the ankle block is hinged with the quick-release assembly, the ankle block is fastened to the tensioning block, the tensioning block is hinged with the foot block, and the quick-release assembly is hinged with the foot instep block.

[0018] By adopting the above technical solution, the foot block, as the base, slides into the slot of the spacing block and engages with the foot contact block, while simultaneously abutting and pushing out the elastic element. The opening and closing block is tightly connected to the ankle block and hinged to the foot block, allowing the ankle block to open or close relative to the foot block, facilitating the placement of the patient's foot. The quick-release component is hinged to both the ankle block and the instep block, pressing the instep block firmly onto the patient's instep when closed. The fixed elastic element, sleeved between the foot block and the instep block, provides adaptive elastic tightening force. In an emergency or when the care is finished, the quick-release component is operated to quickly unlock and detach the instep block and the ankle block. All components work together to achieve the effects of all-round stable wrapping of the foot, adaptive elastic tightening, and one-button quick release.

[0019] Furthermore, the quick-release assembly includes a quick-release elastic element, a quick-release buckle, a locking block, a supporting elastic element, and a supporting column. The quick-release buckle and the ankle block are slidably connected, the quick-release buckle and the locking block are locked together, the quick-release buckle and the quick-release elastic element are fastened together, the quick-release elastic element and the ankle block are fastened together, the locking block and the ankle block are hinged together, the supporting column and the instep block are hinged together, the supporting column and the locking block are slidably connected, the supporting elastic element and the locking block are fastened together, and the supporting elastic element and the supporting column are fastened together.

[0020] By adopting the above technical solution, the support column is hinged to the instep block and slidably connected to the release block hinged to the ankle block. The support elastic element is connected between the release block and the support column to provide support and buffer force. When locked, the quick release buckle slidably connected to the ankle block is locked by the elastic force of the fastened quick release elastic element, locking the relative position of the support column and the release block, thus achieving a stable pressing of the instep block. When quick release is required, pressing the quick release buckle overcomes the elastic force of the quick release elastic element, slides on the ankle block, and disengages from the release block. After the release block loses its lock, it rotates around the hinge point, and the support elastic element instantly releases its elastic force, pushing the support column to slide quickly out along the release block, so that the instep block is released instantly. This achieves a clutch control function with a compact structure, reliable locking, and emergency quick release.

[0021] Furthermore, the popliteal fossa bending mechanism includes a popliteal fossa support block, a first linkage slide rod, a second linkage slide rod, and an abutment rod. Both the first and second linkage slide rods are drivenly connected to the popliteal fossa support block. The first and second linkage slide rods are spatially perpendicular. The abutment rod is drivenly connected to the first linkage slide rod, and the second linkage slide rod is slidably connected to the first linkage slide rod. The drive mechanism is drivenly connected to the abutment rod, and the drive mechanism is drivenly connected to the second linkage slide rod. Both the first and second linkage slide rods are slidably connected to the nursing tank. The first linkage slide rod is drivenly connected to the water circulation mechanism.

[0022] By adopting the above technical solution, the drive mechanism is activated and connected to the second linkage slide rod and the abutment rod respectively. The abutment rod drives the first linkage slide rod, which is set vertically in space, to slide on the nursing tank. The second linkage slide rod maintains a sliding connection with the first linkage slide rod and is driven synchronously. The two work together to drive the popliteal support block to move up and down and translate in a compound manner in the vertical and horizontal directions, directly supporting and driving the patient's popliteal fossa to perform flexion and extension movements in the physiological cycle. At the same time, the first linkage slide rod is synchronously connected to the water circulation mechanism during the sliding process and drives it to perform linkage pump water rinsing, realizing the synchronous and automated operation of the patient's passive flexion and extension rehabilitation movement of the popliteal joint and water rinsing massage care.

[0023] Furthermore, the water circulation mechanism includes a water tank, a circulating water pump, a reciprocating rack, blades, a ratchet wheel assembly, and a reciprocating belt. The reciprocating rack is fastened to the first linkage slide rod, the reciprocating rack is driven by the ratchet wheel assembly, the ratchet wheel assembly is driven by the blades, the ratchet wheel assembly is driven by the reciprocating belt, the water tank is connected to the circulating water pump, the water tank is connected to the nursing tank, and the nursing tank is connected to the circulating water pump.

[0024] By adopting the above technical solution, the circulating water pump starts to inject the care water in the water tank into the care tank and form a closed-loop water circulation. When the first linkage slide rod moves back and forth, it drives the reciprocating rack fastened to it to move synchronously. The reciprocating rack drives the ratchet wheel group to rotate through the gear rack transmission. The rotation of the ratchet wheel group then drives the blades connected to the transmission to rotate and stir rapidly in the water flow in the tank to generate pulsating water waves. At the same time, the ratchet wheel group drives the relevant water flow oscillation structure through the reciprocating belt transmission. This achieves the dual technical effect of using mechanical linkage to drive the underwater blades to rotate and create waves without the need for an additional underwater motor, thereby enhancing the medicated bath cleaning effect and the comfort of water flow massage.

[0025] Furthermore, the drive mechanism includes a seat, a reciprocating hydraulic cylinder, and an adjusting hydraulic cylinder. The seat and the care tank are slidably connected. The seat and the second linkage slide are driven together. The adjusting hydraulic cylinder and the seat are driven together. The adjusting hydraulic cylinder and the care tank are fastened together. The reciprocating hydraulic cylinder and the abutment rod are driven together. The reciprocating hydraulic cylinder and the extension block are driven together.

[0026] By adopting the above technical solution, the adjusting hydraulic cylinder fastened to the nursing tank is activated and drives the seat to slide along the nursing tank through transmission to adaptively adjust the patient's sitting position. At the same time, the seat is connected to the second linkage slide rod to synchronously adjust the popliteal support position. The reciprocating hydraulic cylinder is activated and drives the abutment rod and extension block to perform periodic reciprocating motion through transmission connection. This synchronously drives the popliteal flexion mechanism and the leg opening mechanism to perform compound extension and flexion and opening and closing rehabilitation movements, achieving the effects of dynamic fine adjustment of the patient's overall sitting position, efficient single-power-source drive of multi-joint compound movements of the lower limbs, and smooth control of overall nursing movements.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] The spacing motor drives the spacing screw to move the spacing block along the spacing slide to adjust the distance between the legs. The foot abuts against the elastic element to flexibly press against the foot block in the groove. When the extension block slides to the release position, the pop-out blocks on both sides push the first and second pop-out rods to open and unlock the foot abutment block. The energy-stored push-out elastic element pushes the foot block out. In conjunction with the quick release component, the quick release buckle is pressed to release the release block. The support column slides away from the instep block under the action of the support elastic element, realizing the foot adaptive clamping, precise adjustment of the lateral spacing and automatic mechanical release in emergency situations. The first and second linkage slide rods, which are arranged vertically in space, slide and cooperate to drive the popliteal support block to perform a composite motion of lifting and translating, which drives the popliteal joint to flex and extend. The sliding first linkage slide rod directly drives the reciprocating rack fastened to it to translate, and the transmission drives the ratchet wheel group and blades to rotate in the nursing tank to generate pulsating water waves, which are then oscillated by the reciprocating belt drive. Eliminating the need for an independent underwater motor, this system utilizes mechanical linkage to achieve synchronized and automated popliteal flexion and extension rehabilitation training with water rinsing and massage. The adjusting hydraulic cylinder on the nursing tank drives the seat to slide and finely adjust the patient's sitting posture. A single reciprocating hydraulic cylinder simultaneously transmits and connects the abutment rod and the extension / flexion block, achieving single-power source coordinated drive for leg opening and closing and popliteal flexion. The integrated suction and suction air pump is connected to the elastic airbag inside the upper cover. By inflating, the airbag adaptively expands to fit the torso for painless wrapping. When deflating, it quickly contracts, achieving efficient linkage of multiple mechanisms and flexible anti-pressure injury protection for the torso within the sealed tank.

[0042] By adopting the above technical solution, the box mechanism 6 serves as the main support and protection body of the entire device. The water circulation mechanism 3 is connected to the box mechanism 6 to realize the flow and circulation of bathing and rinsing liquids. The patient's body is placed inside the box mechanism 6. The foot fixing mechanism 1 and the leg opening mechanism 2 are engaged to realize the restraint and positioning of the patient's feet and lower limbs. The drive mechanism 5 is fixedly installed on the box mechanism 6 and is connected to the leg opening mechanism 2, the popliteal fossa flexion mechanism 4 and the water circulation mechanism 3 respectively. The leg opening mechanism 2 is driven to slide on the box mechanism 6 to realize the lateral opening and closing movement of the legs. At the same time, the popliteal fossa flexion mechanism 4 is driven to slide on the box mechanism 6 to drive the patient's knee and popliteal fossa to flex, extend and lift. It also works in conjunction with the water circulation mechanism 3 to perform medicated bath or water flow rinsing and massage. The efficient linkage and cooperation of each mechanism achieves the effects of adaptive fixation of the lower limbs of bedridden patients, rehabilitation care of leg opening and closing and popliteal fossa flexion and extension, water washing and cleaning and massage.

[0043] Furthermore, the housing mechanism 6 includes an upper cover 61, a nursing tank 62, and a body fixing component 63.

[0044] By adopting the above technical solution, the nursing tank 62 constitutes a closed and bathing cavity that supports the patient's lower limbs and torso. The upper cover 61 is hinged to the nursing tank 62 so that it can be opened or closed for sealing. The body fixation component 63 is fastened to the inside of the upper cover 61. When the upper cover 61 is closed, it applies a stable and flexible limiting fixation to the patient's upper torso. The drive mechanism 5 is fastened to the nursing tank 62 and drives the leg opening mechanism 2 and the popliteal fossa bending mechanism 4, which are slidably connected to the nursing tank 62, to perform translation and flexion and extension movements along the tank. The water circulation mechanism 3 is connected to the nursing tank 62 to realize the injection and circulation of nursing fluid and the effects of rinsing and massaging. All components work together to realize the rapid construction of a safe nursing space, stable protection of the body, and guidance of nursing movements.

[0045] Furthermore, the body fixation component 63 includes an integrated suction air pump 64 and an elastic airbag 65. The integrated suction air pump 64 is securely connected to the care tank 62, the elastic airbag 65 is securely connected to the top cover 61, and the integrated suction air pump 64 and the elastic airbag 65 are connected.

[0046] By adopting the above technical solution, the suction-absorption integrated air pump 64 is securely installed on the nursing tank 62 and is connected to the elastic airbag 65, which is securely fixed to the inner wall of the upper cover 61, through an air passage. When the patient lies in the tank and the upper cover 61 is fastened, the suction-absorption integrated air pump 64 starts to inflate, causing the elastic airbag 65 to expand rapidly and flexibly conform to the patient's body surface, achieving individualized and stable wrapping and protection without pressure pain. When the nursing is completed or when it is necessary to open the upper cover 61, the suction-absorption integrated air pump 64 reverses to perform air extraction, causing the elastic airbag 65 to quickly deflate and contract to release the patient's body, achieving the beneficial effects of flexible anti-pressure injury, adaptive fit, and rapid detachment and closure during the body fixation process.

[0047] Furthermore, the leg opening mechanism 2 includes an extension block 21, a spacing screw 22, a spacing slide bar 23, a spacing motor 24, a spacing block 25, a foot abutment block 26, a foot abutment elastic element 27, and a pop-out assembly 28. The spacing motor 24 and the spacing screw 22 are connected by transmission, the spacing screw 22 and the spacing block 25 are connected by transmission, the spacing block 25 and the extension block 21 are slidably connected, the drive mechanism 5 and the extension block 21 are connected by transmission, the extension block 21 and the nursing tank 62 are slidably connected, the spacing block 25 and the spacing slide bar 23 are slidably connected, the foot abutment block 26 and the spacing block 25 are slidably connected, the foot abutment elastic element 27 and the spacing block 25 are fastened together, the foot abutment elastic element 27 and the foot abutment block 26 are fastened together, the foot fixing mechanism 1 and the foot abutment block 26 are engaged, the spacing block 25 is provided with a locking groove 251, the foot fixing mechanism 1 and the locking groove 251 are slidably connected, and the pop-out assembly 28 abuts against the foot fixing mechanism 1.

[0048] By adopting the above technical solution, the drive mechanism 5 drives the extension block 21 to slide back and forth along the nursing groove 62 to realize the extension and flexion adjustment of the legs. The spacing motor 24 starts and drives the spacing screw 22 to rotate. Through the threaded transmission, the spacing block 25 slides along the spacing slide bar 23 and the extension block 21 to adjust the lateral extension spacing of the two legs on both sides. The foot fixing mechanism 1 slides into the locking groove 251 provided on the spacing block 25 and locks with the foot abutment block 26. The two ends of the foot abutment elastic member 27 are respectively fastened to the spacing block 25 and the foot abutment block 26, providing buffer and flexible clamping force when clamping the foot. When the nursing is completed and it needs to be removed, the pop-out component 28 is controlled to abut and drive the foot fixing mechanism 1 and trigger to release the locking, so that the foot fixing mechanism 1 pops out smoothly from the locking groove 251, realizing the electric adjustment of the leg spacing, the flexible elastic clamping of the foot, and the rapid pop-out and removal of the foot fixing mechanism 1.

[0049] Furthermore, the pop-out assembly 28 includes a pop-out block 281, a pop-out elastic element 282, a push-out elastic element 283, a first pop-out rod 284, and a second pop-out rod 285. An even number of foot abutment blocks 26 are provided, with each pair of foot abutment blocks 26 located on either side of the locking groove 251. Two pop-out blocks 281 are provided, located on either side of the extension block 21. The pop-out blocks 281 and extension block 21 are fastened together. The first pop-out rod 284 is hinged to the spacing block 25. The first pop-out rod 284 is fastened to the pop-out elastic element 282. The pop-out elastic element 282 is fastened to the spacing block 25. The pop-out block 281 and the first pop-out rod 284 are driven together. The first pop-out rod 284 is driven together to the foot abutment block 26. The pop-out block 281 and the second pop-out rod 285 are driven together. The second pop-out rod 285 is fastened to the foot abutment block 26. The push-out elastic element 283 abuts against the foot fixing mechanism 1. The push-out elastic element 283 and the spacing block 25 are fastened together.

[0050] By adopting the above technical solution, an even number of foot abutment blocks 26 are symmetrically arranged on both sides of the locking groove 251. When the extension block 21 moves to the disengagement position, the two pop-out blocks 281 fastened to both sides of the extension block 21 respectively engage with the first pop-out rod 284 and the second pop-out rod 285 hinged on the spacing block 25. This drives the first pop-out rod 284 to swing against the tension of the pop-out elastic element 282, causing the foot abutment block 26 connected to it to open outward and release the locking. At the same time, the second pop-out rod 285 is pushed by the pop-out block 281 to move out of the foot abutment block 26 fastened to it. The push-out elastic element 283, which was originally in a compressed and stored state and fastened to the spacing block 25, releases its elastic force, directly abuts and forcefully pushes the foot fixing mechanism 1 out of the locking groove 251, thus realizing the linkage unlocking of the foot fixing state and the automatic mechanical push-out discharge.

[0051] Furthermore, the foot fixing mechanism 1 includes a foot block 11, a fixing elastic element 12, a foot instep block 13, an ankle block 14, a tensioning block 15, and a quick-release assembly 16. The foot block 11 is slidably connected to the locking groove 251, the foot block 11 is engaged with the foot abutment block 26, the foot block 11 abuts against the push-out elastic element 283, the fixing elastic element 12 is sleeved with the foot block 11, the fixing elastic element 12 is sleeved with the foot instep block 13, the ankle block 14 is hinged with the quick-release assembly 16, the ankle block 14 is fastened to the tensioning block 15, the tensioning block 15 is hinged with the foot block 11, and the quick-release assembly 16 is hinged with the foot instep block 13.

[0052] By adopting the above technical solution, the foot block 11, as the base, slides into the slot 251 of the spacing block 25 and engages with the foot contact block 26, while simultaneously engaging and pushing out the elastic element 283. The opening and closing block 15 is fastened to the ankle block 14 and hinged to the foot block 11, so that the ankle block 14 can open or close relative to the foot block 11 to facilitate the placement of the patient's foot. The quick-release component 16 is hinged to the ankle block 14 and the instep block 13 respectively. When closed, it presses the instep block 13 tightly onto the patient's instep. The fixed elastic element 12, which is sleeved between the foot block 11 and the instep block 13, provides an adaptive elastic tightening force. In an emergency or when the care is finished, the quick-release component 16 is operated to quickly unlock and release the instep block 13 and the ankle block 14. All components work together to achieve the effects of all-round stable wrapping of the foot, adaptive elastic tightening, and one-button quick release.

[0053] Furthermore, the quick-release assembly 16 includes a quick-release elastic element 161, a quick-release buckle 162, a locking block 163, a supporting elastic element 164, and a supporting column 165. The quick-release buckle 162 is slidably connected to the ankle block 14, the quick-release buckle 162 is locked to the locking block 163, the quick-release buckle 162 is fastened to the quick-release elastic element 161, the quick-release elastic element 161 is fastened to the ankle block 14, the locking block 163 is hinged to the ankle block 14, the supporting column 165 is hinged to the instep block 13, the supporting column 165 is slidably connected to the locking block 163, the supporting elastic element 164 is fastened to the locking block 163, and the supporting elastic element 164 is fastened to the supporting column 165.

[0054] By adopting the above technical solution, the support column 165 is hinged to the instep block 13 and slidably connected to the release block 163 hinged to the ankle block 14. The support elastic element 164 is connected between the release block 163 and the support column 165 to provide support and buffering force. When locked, the quick release buckle 162 slidably connected to the ankle block 14 locks the release block 163 under the elastic force of the fastened quick release elastic element 161, locking the relative position of the support column 165 and the release block 163, thus achieving... The foot instep block 13 is firmly pressed. When quick release is required, pressing the quick release buckle 162 overcomes the elastic force of the quick release elastic element 161, slides on the ankle block 14, and disengages from the locking block 163. After the locking block 163 loses its lock, it rotates around the hinge point. The supporting elastic element 164 releases its elastic force instantly, pushing the supporting column 165 to slide quickly out along the locking block 163, so that the foot instep block 13 is released instantly. This achieves a clutch control function that is compact in structure, reliable in locking, and quick in emergency release.

[0055] Furthermore, the popliteal fossa bending mechanism 4 includes a popliteal fossa support block 41, a first linkage slide rod 42, a second linkage slide rod 43, and an abutment rod 44. The first linkage slide rod 42 and the second linkage slide rod 43 are both drivenly connected to the popliteal fossa support block 41. The first linkage slide rod 42 and the second linkage slide rod 43 are spatially perpendicular. The abutment rod 44 is drivenly connected to the first linkage slide rod 42. The second linkage slide rod 43 is slidably connected to the first linkage slide rod 42. The drive mechanism 5 is drivenly connected to the abutment rod 44. The drive mechanism 5 is also drivenly connected to the second linkage slide rod 43. The first linkage slide rod 42 and the second linkage slide rod 43 are both slidably connected to the nursing tank 62. The first linkage slide rod 42 is drivenly connected to the water circulation mechanism 3.

[0056] By adopting the above technical solution, the drive mechanism 5 is activated and connected to the second linkage slide rod 43 and the abutment rod 44 respectively. The abutment rod 44 drives the first linkage slide rod 42, which is set vertically in space, to slide on the nursing tank 62. The second linkage slide rod 43 and the first linkage slide rod 42 are connected in a sliding manner and are driven synchronously. The two work together to drive the popliteal support block 41 to move up and down in a compound manner in the vertical and horizontal directions, directly supporting and driving the patient's popliteal fossa to perform flexion and extension movements in physiological cycle. At the same time, the first linkage slide rod 42 is connected to the water circulation mechanism 3 in a synchronous manner during the sliding process and drives it to perform linkage pump water rinsing, realizing the synchronous and automated operation of the patient's passive flexion and extension rehabilitation movement of the popliteal joint and water rinsing massage care.

[0057] Furthermore, the water circulation mechanism 3 includes a water tank 31, a circulating water pump 32, a reciprocating rack 33, a blade 34, a ratchet wheel assembly 35, and a reciprocating belt 36. The reciprocating rack 33 is fastened to the first linkage slide rod 42. The reciprocating rack 33 is driven to the ratchet wheel assembly 35. The ratchet wheel assembly 35 is driven to the blade 34. The ratchet wheel assembly 35 is driven to the reciprocating belt 36. The water tank 31 is connected to the circulating water pump 32. The water tank 31 is connected to the nursing tank 62. The nursing tank 62 is connected to the circulating water pump 32.

[0058] By adopting the above technical solution, the circulating water pump 32 starts to inject the nursing water in the water tank 31 into the nursing tank 62 and form a closed-loop water circulation. When the first linkage slide rod 42 moves back and forth, it drives the reciprocating rack 33 fastened to it to move synchronously. The reciprocating rack 33 drives the ratchet wheel assembly 35 to rotate through the gear and rack transmission. The rotation of the ratchet wheel assembly 35 drives the blade 34 connected to the transmission to rotate and stir rapidly in the water flow in the tank to generate pulsating water waves. At the same time, the ratchet wheel assembly 35 drives the relevant water flow swing structure through the reciprocating belt 36. This achieves the dual technical effect of driving the underwater blade 34 to rotate and create waves by mechanical linkage without the need for an additional underwater motor, thereby enhancing the medicated bath cleaning effect and the comfort of water flow massage.

[0059] Furthermore, the drive mechanism 5 includes a seat 51, a reciprocating hydraulic cylinder 52, and an adjusting hydraulic cylinder 53. The seat 51 and the care tank 62 are slidably connected. The seat 51 and the second linkage slide rod 43 are drivenly connected. The adjusting hydraulic cylinder 53 and the seat 51 are drivenly connected. The adjusting hydraulic cylinder 53 and the care tank 62 are fastened together. The reciprocating hydraulic cylinder 52 and the abutment rod 44 are drivenly connected. The reciprocating hydraulic cylinder 52 and the extension block 21 are drivenly connected.

[0060] By adopting the above technical solution, the adjusting hydraulic cylinder 53, which is fastened to the nursing trough 62, is activated and drives the seat 51 to slide along the nursing trough 62 through transmission, so as to adaptively adjust the patient's sitting position. The seat 51 is simultaneously connected to the second linkage slide rod 43 to synchronously adjust the popliteal support position. The reciprocating hydraulic cylinder 52 is activated and drives the abutment rod 44 and the extension block 21 to perform periodic reciprocating motion through transmission connection. This synchronously drives the popliteal flexion mechanism 4 and the leg opening mechanism 2 to perform compound extension and flexion rehabilitation movements, thus achieving the effects of dynamic fine adjustment of the patient's overall sitting position, efficient single-power-source drive of multi-joint compound movements of the lower limbs, and smooth control of overall nursing movements.

[0061] Working principle of the invention:

[0062] The spacing motor 24 drives the spacing screw 22 to move the spacing block 25 along the spacing slide bar 23 to adjust the leg spacing. The foot abuts against the elastic element 27 to flexibly press against the foot block 11 in the groove 251. When the extension block 21 slides to the release position, the pop-out blocks 281 on both sides push the first pop-out rod 284 and the second pop-out rod 285 to make the foot abutment block 26 open outward and unlock. The energy-stored push-out elastic element 283 pushes the foot block 11 out. In conjunction with the quick release assembly 16, the quick release buckle 162 is pressed to release the release block 163. The support column 165 supports the elastic element 16. Under the action of 4, the foot instep block 13 is slid out, realizing the foot adaptive clamping, precise adjustment of lateral spacing and automatic mechanical ejection and disassembly in emergency situations. The first linkage slide rod 42 and the second linkage slide rod 43, which are arranged vertically in space, slide and cooperate to drive the popliteal support block 41 to perform a composite motion of lifting and translating, which drives the popliteal joint to flex and extend. The sliding first linkage slide rod 42 directly drives the reciprocating rack 33 fastened to it to translate, and drives the ratchet wheel group 35 and the blade 34 to rotate in the nursing tank 62 to generate pulsating water waves, which are then driven to swing through the reciprocating belt 36. Eliminating the need for an independent underwater motor, the system utilizes mechanical linkage to achieve synchronized and automated popliteal flexion and extension rehabilitation training with water rinsing and massage. The adjusting hydraulic cylinder 53 on the nursing tank 62 drives the seat 51 to slide and finely adjust the patient's sitting posture. A single reciprocating hydraulic cylinder 52 simultaneously transmits and connects the abutment rod 44 and the extension block 21, achieving single-power source coordinated drive for leg opening and closing and popliteal flexion. The integrated suction and suction air pump 64 is connected to the elastic airbag 65 inside the upper cover 61. By inflating, the airbag adaptively expands to fit the torso for painless wrapping. When deflating, it quickly contracts, achieving efficient linkage of multiple mechanisms and flexible anti-pressure injury protection of the torso within the sealed tank.
