DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.
[0021] Please refer to Figures 1-13 The present application provides a technical solution: a diabetic foot care device, comprising a seat 1 and a support frame 2 arranged on the support legs 11 at the bottom of the seat 1, further comprising: a thigh support unit 3, which is arranged on the support frame 2 in a liftable manner and is used for supporting the thigh of a patient; a calf support unit 4, which is arranged on the support frame 2 and connected with the thigh support unit 3, and is used for being turned up to support the calf of the patient when the thigh of the patient presses down the thigh support unit 3; and a fixing unit 5, which is arranged on the calf support unit 4 and connected with the thigh support unit 3, and is used for fixing the calf placed on the calf support unit 4.
[0022] It should be noted that during the work, when the patient's diabetic foot is medicated and nursed, the patient sits on the seat 1, and then places the thighs on the thigh support unit 3. The weight of the thighs will force the thigh support unit 3 to move downward in the support frame 2, and will push the calf support unit 4 to overturn outward along the support frame 2 during the downward movement of the thigh support unit 3, and then lift the patient's calf placed above the calf support unit 4. When the thigh support unit 3 moves to the set position, it is fixed with the support frame 2, so that the calf support unit 4 lifts the patient's calf to the set height and is fixed, which is convenient for medical staff to nurse and treat the patient's diabetic foot. During the rotation of the calf support unit 4, the thigh support unit 3 drives the fixed unit 5 to move, so that the fixed unit 5 clamps and fixes the patient's calf placed on the calf support unit 4. Through the linkage design of the thigh support unit 3 and the calf support unit 4, when the patient places the thighs on the thigh support unit 3 and presses the thigh support unit 3 downward, the calf support unit 4 can automatically lift the patient's calf, without the patient lifting the calf by himself, improving the use comfort of the patient, and the patient's calf can be fixed, so that the patient's calf does not move during the nursing process, improving the efficiency of the nursing work.
[0023] In an embodiment, the support frame 2 comprises: a fixed frame 21, which is hollow and fixed on the support leg 11, for supporting the thigh support unit 3; and a mounting frame 22, which is arranged on the top of the fixed frame 21 and is used for mounting the calf support unit 4. The mounting frame 22 is provided with a swing groove 2201 for the movement of the calf support unit 4, and is provided with a through groove 2202 for the movement of the thigh support unit 3.
[0024] In this way, referring to Figure 3 , and Figures 11-12 , the support frame 2 is composed of two independent and mutually cooperating parts, the fixed frame 21 and the mounting frame 22. The fixed frame 21 is hollow and fixed on the support leg 11. The thigh support unit 3 is inserted into the fixed frame 21 from the top of the fixed frame 21. When the patient presses the thigh support unit 3 downward, the thigh support unit 3 will be forced to move downward in the fixed frame 21. The mounting frame 22 is fixed at the top end of the fixed frame 21 and forms an inverted L-shaped mechanism with the fixed frame 21. The calf support unit 4 is fixed in the inside of the mounting frame 22 and is connected with the thigh support unit 3 in the inside of the fixed frame 21. Under the pushing of the thigh support unit 3, the calf support unit 4 swings along the mounting frame 22 to support the patient's calf placed on the calf support unit 4.
[0025] In an embodiment, the thigh supporting unit 3 comprises: a rack 32 arranged on the top of the fixed frame 21; a supporting ring 31 fixed on the top of the rack 32 and designed in a circular arc shape for supporting the thigh of the patient; a sealing plate 33 fixed on the bottom of the rack 32 and abutting against the inner wall of the fixed frame 21 for guiding the supporting ring 31; and a first elastic member 34 arranged at the bottom end of the sealing plate 33 and connected with the inner wall of the fixed frame 21.
[0026] In this way, when the patient places the thigh inside the supporting ring 31, the thigh will press the supporting ring 31 downward under the action of gravity, thereby driving the rack 32 to move downward in the fixed frame 21, and further driving the sealing plate 33 fixed at the bottom end of the rack 32 to move downward along the inner wall of the fixed frame 21, and the sealing plate 33 will press the first elastic member 34. Figure 5 Figure 6 The first elastic member 34 is made of a spring with damping or an elastic pad, which can elastically support the leg of the patient. When the patient finishes the nursing and moves the thigh away from the supporting ring 31, the first elastic member 34 can drive the supporting ring 31 to move upward under the elastic action, and the sealing plate 33 abuts against the inner wall of the fixed frame 21, which not only plays an auxiliary supporting role, but also guides the movement of the rack 32. During the lifting and lowering of the rack 32, the sealing plate 33 slides along the inner wall of the fixed frame 21, which ensures that the rack 32 can only move linearly in the vertical direction, avoiding the deviation or jamming of the rack 32 during the movement, and improving the stability and reliability of the movement of the thigh supporting unit 3.
[0027] In an embodiment, the thigh supporting unit 3 further comprises: a mounting shaft 36 arranged in the mounting frame 22; and a gear 35 fixed on the mounting shaft 36 and engaged with the rack 32 for mounting the calf supporting unit 4.
[0028] In this way, during the downward movement of the rack 32, the rack 32 will engage with the gear 35, driving the gear 35 to rotate, and further driving the mounting shaft 36 to rotate in the mounting frame 22, so that the mounting shaft 36 drives the calf supporting unit 4 fixed on the upper end of the mounting shaft 36 to rotate counterclockwise along the mounting shaft 36, lifting the calf of the patient placed on the upper end of the calf supporting unit 4. Figure 5 When the patient presses the supporting ring 31 with the thigh, the gear 35 engaged with the rack 32 will rotate, and the rotation of the gear 35 can drive the calf supporting unit 4 to flip upward, thereby achieving the support of the calf. This linkage mode simulates the movement logic of the human leg during the natural change of sitting posture, making the movements of the thigh and the calf more coordinated and natural, and helping to reduce the discomfort of the patient when lifting the calf during the nursing process.
[0029] In an embodiment, the thigh supporting unit 3 further comprises a positioning assembly 37 arranged on the fixing frame 21 and connected with the rack 32, for fixing the rack 32 lowered to a set position.
[0030] In this way, referring to Figs. 1 and 2, the positioning assembly 37 is arranged on the fixing frame 21 and connected with the rack 32, and when the rack 32 is lowered to a set position, the positioning assembly 37 can fix the rack 32. During the nursing of the patient with diabetic foot, the lower leg of the patient needs to be stably placed on the lower leg supporting unit 4, and the presence of the positioning assembly 37 effectively fixes the overturning of the lower leg supporting unit 4, ensuring that the lower leg supporting unit 4 always maintains a set angle, thereby providing stable and reliable support for the lower leg of the patient. Figures 1-4 Figures 11-12 In this way, referring to Figs. 1 and 2, the positioning assembly 37 is arranged on the fixing frame 21 and connected with the rack 32, and when the rack 32 is lowered to a set position, the positioning assembly 37 can fix the rack 32. During the nursing of the patient with diabetic foot, the lower leg of the patient needs to be stably placed on the lower leg supporting unit 4, and the presence of the positioning assembly 37 effectively fixes the overturning of the lower leg supporting unit 4, ensuring that the lower leg supporting unit 4 always maintains a set angle, thereby providing stable and reliable support for the lower leg of the patient.
[0031] In an embodiment, the positioning assembly 37 comprises a fixing cylinder 371 fixed in the inside of the fixing frame 21, for providing a moving space for components; an abutting ring 372 fixed in the inside of the fixing cylinder 371; a moving rod 373 arranged on the abutting ring 372; a positioning ball 375 arranged on one side of the moving rod 373 close to the rack 32 and inserted into a positioning groove 3201 formed on the rack 32, for fixing the rack 32 when the positioning groove 3201 on the rack 32 is aligned with the positioning ball 375; a limiting plate 374 fixed on the moving rod 373, for limiting the moving position of the moving rod 373; and a second elastic member 376 sleeved on the moving rod 373 and located between the abutting ring 372 and the limiting plate 374.
[0032] In this way, referring to Figs. 1 and 2, the positioning assembly 37 is arranged on the fixing frame 21 and connected with the rack 32, and when the rack 32 is lowered to a set position, the positioning assembly 37 can fix the rack 32. During the nursing of the patient with diabetic foot, the lower leg of the patient needs to be stably placed on the lower leg supporting unit 4, and the presence of the positioning assembly 37 effectively fixes the overturning of the lower leg supporting unit 4, ensuring that the lower leg supporting unit 4 always maintains a set angle, thereby providing stable and reliable support for the lower leg of the patient. Figure 11 Figure 12 The positioning ball 375 is located on the side of the moving rod 373 near the rack 32 and can be inserted into the positioning groove 3201 on the rack 32. When the rack 32 moves down and the positioning groove 3201 aligns with the positioning ball 375, the positioning ball 375 will insert into the positioning groove 3201, thus fixing the rack 32. The fixing cylinder 371 is fixed inside the fixing frame 21, providing a stable installation space and moving track for the entire positioning assembly 37. The abutment ring 372 is fixed inside the fixing cylinder 371, and the moving rod 373 passes through the abutment ring 372. The abutment ring 372 guides the movement of the moving rod 373, ensuring that the moving rod 373 moves along a fixed direction, thereby enabling the positioning ball 375 to move accurately towards the positioning groove 3201. This further improves the accuracy of positioning. When the patient's leg is not placed on the upper end of the support ring 31, the positioning ball 375 abuts against the side of the rack 32. At this time, the limiting plate 374 squeezes the second elastic element 376, which is made of a damped spring or elastic pad. When the positioning ball 375 is aligned with the positioning groove 3201, the second elastic element 376 will push the positioning ball 375 to move into the positioning groove 3201, so that the positioning ball 375 is locked and fixed in the positioning groove 3201. By setting the positioning component 37, the downward movement position of the rack 32 can be automatically limited, the flipping angle of the lower leg support unit 4 can be fixed, and the angle at which the patient's lower leg is raised can be fixed, which makes it convenient for medical staff to care for the patient's foot.
[0033] In one embodiment, the calf support unit 4 includes: a mounting plate 41, fixed on the mounting shaft 36 and symmetrically arranged about the gear 35; a swing rod 42, arranged on the mounting plate 41 and having an L-shaped structure; and a placement ring 43, spaced apart on the swing rod 42 and having an arc-shaped design, for supporting the patient's calf.
[0034] This design is for reference. Figures 1-6 The mounting plate 41 is fixed on the mounting shaft 36 and is symmetrically arranged about the gear 35. This symmetrical structure enables the lower leg support unit 4 to maintain balance when subjected to force. When the mounting shaft 36 rotates, it will drive the mounting plate 41 to rotate, which in turn drives the swing rod 42 to rotate counterclockwise along the mounting shaft 36, thereby causing the placement ring 43 to lift the patient's lower leg. When the patient places his lower leg on the placement ring 43, the mounting plate 41 can evenly distribute the pressure applied to the leg, avoiding the placement ring 43 from tilting or shaking due to excessive force on one side, providing stable and reliable support for the patient's lower leg, and reducing discomfort and safety hazards caused by unstable support.
[0035] In one embodiment, the calf support unit 4 further includes: a foot support assembly 44 disposed on the side of the swing rod 42 away from the mounting plate 41 for supporting the patient's foot; the foot support assembly 44 includes: a fixed plate 441 fixed to the side of the swing rod 42 away from the mounting plate 41; a lifting rod 442 passing through the fixed plate 441; a foot pedal 445 fixed to the side of the lifting rod 442 away from the mounting plate 41 for placing the patient's foot; an anti-drop plate 443 fixed to the side of the lifting rod 442 away from the foot pedal 445 for restricting the movement of the lifting rod 442; and a third elastic member 444 sleeved on the lifting rod 442 and located between the fixed plate 441 and the anti-drop plate 443.
[0036] This design is for reference. Figures 1-6 When the patient's lower leg is placed on the placement ring 43, the foot is connected to the foot pedal 445. When the foot is placed on the foot pedal 445, it will push the foot pedal 445 to move away from the swing rod 42, thereby causing the lifting rod 442 to move on the fixed plate 441. The anti-detachment plate 443 on the lifting rod 442 compresses the third elastic element 444. The third elastic element 444 is made of a damped spring or elastic pad, which allows the foot pedal 445 to have a certain amount of movement space. The distance between the foot pedal 445 and the swing rod 42 can be adjusted according to the length of the patient's leg, thereby improving the practicality of the device.
[0037] In one embodiment, the fixing frame 21 is provided with an inflation chamber 2101 located below the sealing plate 33, and an exhaust hole 2102 communicating with the inflation chamber 2101 is provided on one side of the fixing frame 21; the fixing unit 5 includes: an inflation pipe 51, which is provided on the fixing frame 21 and communicates with the exhaust hole 2102 on one side and an inflation port 4301 provided on the placement ring 43 on the other side, for discharging the air inside the inflation chamber 2101 into a set position; and a fixing component 52, which is provided in a placement ring 43 and communicates with the inflation pipe 51, for fixing the lower leg placed above the placement ring 43 when the sealing plate 33 moves down inside the fixing frame 21.
[0038] This design is for reference. Figures 5-10 When the support ring 31 pushes the sealing plate 33 to move inside the fixed frame 21, the sealing plate 33 will squeeze the gas inside the inflation chamber 2101 into the exhaust port 2102. The working principle is similar to that of a syringe. The gas inside the inflation chamber 2101 will flow into the placement ring 43 along the inflation tube 51 and push the fixing component 52 inside the placement ring 43 to extend. Then, the patient's lower leg above the placement ring 43 is clamped and fixed to ensure that the lower leg is firmly fixed on the placement ring 43, preventing the leg from moving or shaking during the nursing process, thereby improving the nursing effect.
[0039] In one embodiment, the fixing component 52 includes: a movable plate 521, adjustablely disposed inside the placement ring 43 and abutting against the placement groove 4303 inside the placement ring 43; a fixing clamp 522, which is arc-shaped, adjustablely disposed on the movable plate 521 and extends out of the placement ring 43 on the side away from the movable plate 521; and a fourth elastic member 523, disposed inside the placement groove 4303 and fixedly connected to the movable plate 521.
[0040] This design is for reference. Figures 7-10 When the inflation tube 51 compresses the gas inside the inflation chamber 2101 into the inflation port 4301, the air pressure flows into the placement groove 4303 inside the placement ring 43. Driven by the air pressure, the two symmetrically arranged movable plates 521 move away from the inflation port 4301, thereby causing the fixing clamp 522 to pass through the removal groove 4302 opened at the upper end of the placement ring 43, and then clamp and fix the patient's leg on the placement ring 43. When the movable plates 521 move inside the placement groove 4303, they will compress the fourth elastic member 523. The fourth elastic member is arc-shaped and placed inside the placement groove 4303, and is made of a damped spring or elastic pad.
[0041] In a specific embodiment, see [reference] Figure 11 ,as well as Figure 12 A pull ring 377 is fixed on the side of the moving rod 373 away from the positioning ball 375. After the patient's foot care is completed, the staff pulls the pull ring 377 to pull the positioning ball 375 out of the positioning groove 3201, and then releases the restriction of the positioning ball 375 on the rack 32. Then the patient slowly lifts the thigh and removes the thigh from the support ring 31. The first elastic element 34 pushes the sealing plate 33 to move upward, thereby causing the rack 32 to push the support ring 31 to move upward and reset. During the upward movement of the sealing plate 33, the gas inside the placement groove 4303 is sucked into the inflation chamber 2101. At this time, under the action of the fourth spring 523, the moving plate 521 moves to the side closer to the inflation port 4301, so that the fixing clamp 522 is retracted into the placement groove 4303.
[0042] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification.
