Description

Technical Field

[0001] The invention specifically relates to a rehabilitation nursing device for varicose veins of lower limbs. Background Art

[0002] Varicose veins refer to the appearance of light purple earthworm-like protrusions in the superficial veins of the lower limbs. They are caused by long-term high venous pressure in the lower limbs or congenital valvular insufficiency, which causes local superficial vein dilation and manifests as skin itching. Over time, there may be symptoms such as pigmentation and ulcers. Varicose veins are more common in middle-aged and elderly people and people who work in a standing position for long periods of time, such as teachers, police officers, and those engaged in manual labor, because with age, the condition of blood vessels becomes worse and worse, and the degree of blood vessel dilation becomes greater and greater.

[0003] For example, the Chinese invention patent with publication number CN113476266B provides a system and method for rehabilitation treatment of varicose veins in the lower limbs for vascular surgical care. The invention can adaptively adjust the height of the device according to the user's height and lower limb length, and has two functions for rehabilitation treatment of varicose veins in the lower limbs. By pressing, the severe areas of varicose veins in the user's lower limbs can be pressed to dilate the blood vessels and promote the recovery of varicose veins. At the same time, the thigh part of the patient can be fixed, thereby the lower limb joints are moved through the structure, and this process is driven by the user's hands, providing the user with certain exercise and coordination training.

[0004] However, most of the existing rehabilitation and nursing devices for varicose veins in the lower limbs are externally powered or require patients to operate them themselves, which makes it inconvenient to fully convert the kinetic energy of the patient's movements into force to promote venous return in the lower limbs.

[0043] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0044] Example:

[0045] like Figures 1 to 3 As shown, the present invention provides a rehabilitation nursing device for varicose veins of lower limbs, including two groups of nursing units, which are respectively installed on the patient's legs, and the nursing units each include an inner guard plate 1, and one side of the inner guard plate 1 is provided with an outer guard plate 8 connected by a connecting component, the inner guard plate 1 and the outer guard plate 8 cooperate to form a cavity for accommodating the calf, and the connecting component includes a first strap 6 arranged on the inner guard plate 1 and a second strap 9 arranged on the outer guard plate 8, and the second strap 9 is connected to the first strap 6 by a buckle 7.

[0046] When the device is in use, the inner guard plate 1 and the outer guard plate 8 in each group of nursing units are placed on the inner and outer sides of the calf respectively, and the first strap 6 and the second strap 9 are fixed by the buckle 7. It can be understood that the combined length of the first strap 6 and the second strap 9 can be adjusted by the buckle 7 to adapt to the use of patients with different leg circumferences. The two groups of nursing units are fixed on the patient's legs respectively, and the opposite sides of the inner guard plate 1 and the outer guard plate 8 are provided with protective pads 2. The patient's legs are protected by the protective pads 2 to avoid damage to the legs. A pressure belt 3 made of elastic material is also provided on one side of the inner guard plate 1. The first adhesive tape 4 is provided on the inner side of one end of the pressure belt 3, and the second adhesive tape 5 is provided on the outer side of the other end. Before wearing the device, the pressure belt 3 can also be bound to the patient's calf by the first adhesive tape 4 and the second adhesive tape 5. This can not only prevent the device from directly contacting the patient's legs and prevent the legs from being injured, but also promote venous blood to return to the heart, which has a good effect in preventing varicose veins.

[0047] like Figures 1 to 3 As shown, in the present embodiment, both sides of the outer guard plate 8 are provided with a slide groove 10, and a movable rod 12 is slidably arranged in the slide groove 10. The two groups of movable rods 12 on each group of outer guard plates 8 are fixedly connected in an integrated manner, and multiple groups of dilation frames 13 are hinged at intervals on the movable rod 12. The hinge points of the dilation frames 13 and the movable rods 12 are provided with torsion springs. After the device is worn, under the action of the torsion springs, the multiple groups of dilation frames 13 are brought into contact with the patient's leg muscles, and the leg muscles are pressed and relaxed by controlling the movable rods 12 to slide up and down, thereby achieving the purpose of promoting venous return.

[0048] like Figure 1 , Figures 3 to 5As shown, in this embodiment, the two nursing units are connected by a driving unit to convert the relative motion of the two nursing units into driving the movable rod 12 to slide back and forth in the slide slot 10. The driving unit includes two mounting frames 11, which are fixedly mounted on the two outer guard plates 8, respectively. The two mounting frames 11 are provided with mounting shells 15, and the two mounting shells 15 are provided with winding wheels 21 that can rotate and slide along their axes, and the two ends of the driving rope 24 are respectively wound on the two winding wheels 21. When the patient walks, the two nursing units are driven to move relative to each other, so that the two winding wheels 21 can be controlled to rotate under the action of the driving rope 24.

[0049] like Figure 3 , Figure 4 As shown, in this embodiment, the driving unit also includes two groups of mounting shafts 16, which are rotatably arranged on the two groups of mounting frames 11, and are respectively connected to the two groups of winding wheels 21 through a transmission mechanism, and the winding wheels 21 are driven to reset through the transmission mechanism, and the rotation of the winding wheels 21 in a single direction is converted into driving the mounting shaft 16 to rotate. The mounting shaft 16 is also provided with a linkage assembly connected to the movable rod 12, and the rotation of the mounting shaft 16 is converted into driving the movable rod 12 to slide back and forth through the linkage assembly. The linkage assembly includes a driving column 17 eccentrically arranged on the mounting shaft 16, and one end of the driving rod 25 is hinged to the driving column 17, and the other end is hinged to the movable rod 12.

[0050] During the rotation of the winding wheel 21, the installation shaft 16 is controlled to rotate through the transmission mechanism. During the rotation of the installation shaft 16, the movable rod 12 is driven by the driving rod 25 to slide back and forth in the slide groove 10, so as to drive multiple groups of dilation frames 13 to reciprocate on the calf, and multiple groups of rotatable massage wheels 14 are arranged at intervals on the dilation frames 13. The massage wheels 14 can be used to massage the calf muscles, thereby achieving the effect of rehabilitation care.

[0051] like Figures 3 to 5 As shown, in this embodiment, the transmission mechanism includes a first ratchet disk 18 arranged at the end of the mounting shaft 16, a rotating shaft 19 is arranged on the winding wheel 21, and the rotating shaft 19 is rotatably and slidably arranged along its axis in the mounting shell 15, a second ratchet disk 20 is arranged at the end of the rotating shaft 19, the second ratchet disk 20 is meshed with the first ratchet disk 18, a coil spring 23 is arranged on the rotating shaft 19, and the end of the coil spring 23 is fixedly connected to the mounting shell 15, a first elastic member 22 is arranged on the side of the winding wheel 21 away from the second ratchet disk 20, and the mounting shell 15 is provided with a cover body 26, and the first elastic member 22 abuts against the cover body 26.

[0052] When the patient walks, the drive rope 24 pulls the wire reel 21 to rotate and deform the coil spring 23, and then after the drive rope 24 is relaxed, the wire reel 21 can be reset to rewind the drive rope 24, so that the wire reel 21 can reciprocate in the mounting shell 15. During the forward rotation of the wire reel 21, under the action of the first elastic member 22, the second ratchet disc 20 is engaged with the first ratchet disc 18, so that the first ratchet disc 18 can be driven to rotate by the second ratchet disc 20, so that the mounting shaft 16 rotates to perform rehabilitation movements. During the reverse rotation of the wire reel 21, the second ratchet disc 20 is disengaged from the first ratchet disc 18 by the inclined surface of the ratchet teeth, and the first elastic member 22 is compressed, so that the reset of the wire reel 21 is separated from the movement of the stretching frame 13, so as to prevent the weight and resistance of the stretching frame 13 from affecting the wire reel 21, so that the wire reel 21 can be reset without a large reset force, so as to achieve stable power transmission.

[0053] like Figure 1 , Figures 4 to 6 As shown, in this embodiment, a through slot 27 is opened on the cover body 26, and a rotatable guide wheel 31 is arranged on one side of the through slot 27. The two ends of the driving rope 24 respectively pass through the two groups of through slots 27 and are connected to the winding wheel 21, and the driving rope 24 can be overlapped on the guide wheel 31. A movable block 28 is slidably arranged in the through slot 27, and a second elastic member 29 is arranged between the movable block 28 and the inner wall of the through slot 27. A wedge block 30 is also arranged on one side of the movable block 28. After the movable block 28 slides, the wedge block 30 can abut against the side of the winding wheel 21 away from the second ratchet disk 20.

[0054] When the patient is walking, the driving rope 24 in the rear nursing unit is overlapped on the guide wheel 31 to prevent the driving rope 24 from rubbing against the cover body 26 and breaking. The front set of driving ropes 24 is pulled backward and drives the movable block 28 to slide in the through groove 27 and compress the second elastic member 29. The movable block 28 drives the wedge block 30 to abut against the winding wheel 21 during the sliding process, so that the second ratchet disk 20 in the front nursing unit and the first ratchet disk 18 cannot be disengaged, and the movable block 28 in the rear nursing unit is reset under the action of the second elastic member 29, so that the second ratchet disk 20 in the rear nursing unit and the first ratchet disk 18 are in a disengageable state, so that the positions of the two sets of winding wheels 21 are alternately locked during walking, avoiding the situation where only a single winding wheel 21 rotates due to force imbalance, and stably realizing the synchronous care of both legs, effectively improving the practicality and reliability of the device.

[0055] Specific usage and beneficial effects of the present invention:

[0056] When the device is in use, the two groups of nursing units are fixed on the patient's legs respectively through the inner guard plate 1, the outer guard plate 8 and the connecting assembly. After the nursing units are worn, the multiple groups of dilation frames 13 are in contact with the patient's calves under the action of the torsion springs. During the patient's walking, the driving unit can convert the relative movement of the two groups of nursing units into driving the movable rod 12 to reciprocate in the slide groove 10, so that the dilation frame 13 moves up and down along the patient's calf to promote the patient's venous return and achieve the effect of massaging the patient's calf. The patient does not need to spend special time on nursing work, and no power control is required. The purpose of lower limb varicose vein rehabilitation care can be achieved during daily activities, effectively saving the patient's nursing costs.
