Technical Field

[0001] The present invention relates to the technical field of orthopedic rehabilitation nursing, and specifically relates to a portable orthopedic rehabilitation nursing device. Background Art

[0002] In orthopedic clinical treatment, postoperative rehabilitation nursing of lower limb fractures is a key link in restoring limb function. Traditional rehabilitation methods mostly rely on passive physiotherapy equipment or manual massage, which have obvious limitations: 1. Fixed physiotherapy instruments are bulky and cannot achieve early bedside rehabilitation; 2. They cannot be carried for home care; 3. Manual massage is difficult to accurately control the strength and frequency, and increases the workload of medical staff.

[0003] Especially for patients with calf fractures, the long-term knee flexion state is likely to cause complications such as joint stiffness and deep vein thrombosis, and the existing nursing devices have limited effects in promoting the synergistic effect of bone healing and soft tissue repair. In addition, early fracture rehabilitation needs to balance the protection of the affected limb and moderate activities, and existing equipment is difficult to achieve active-passive combined rehabilitation stimulation in a non-weight-bearing state. Therefore, there is an urgent need to develop a new type of nursing device that integrates biomechanical stimulation, is portable and self-driven, and conforms to the biomechanical principles of orthopedic rehabilitation.

[0014] Beneficial Effects

[0015] The present invention has the following beneficial effects:

[0016] 1. This portable orthopedic rehabilitation nursing device drives the pressing component through the patient's autonomous leg-lifting movement, combines joint range of motion training with soft tissue massage, and realizes the synergistic effect of intermittent axial stress stimulation and muscle pump effect required for bone healing under non-weight-bearing conditions, effectively promoting callus formation and venous return. The arc hole array is combined with an adjustable push rod system to achieve targeted pressing of deep muscles such as the gastrocnemius and soleus.

[0017] The one-way ratchet drive mechanism ensures that effective massage is only produced by lifting the legs, avoiding reverse stress when falling back, and also plays a certain protective role.

[0018] 2. The portable orthopedic rehabilitation nursing device integrates drugs with the cover tube, the calf bracket and mechanical stimulation to promote drug absorption;

[0019] The modular design enables stepless adjustment of knee joint movement to meet the needs of different rehabilitation stages. It also reflects portability and economy.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0036] See also Figures 1-12 The embodiment of the present invention provides a technical solution: a portable orthopedic rehabilitation nursing device, comprising a thigh bracket 1, a groove 13 is provided on the surface of the thigh bracket 1, a limit block 17 is symmetrically installed on the bottom of the thigh bracket 1, a connecting part 2 is movably installed on the limit block 17, a limit hole 6 is provided on the side of the connecting part 2, the limit block 17 is arranged through the limit hole 6, a folding rod 14 is provided at the protruding end of the connecting part 2, a calf bracket 3 is provided on the folding rod 14, an arc hole 11 is equidistantly provided on the inner side of the calf bracket 3, a mounting plate 12 is fixedly installed on the inner side of the arc hole 11, a top pressing component is provided on the inner side of the mounting plate 12, the inner side of the connecting part 2 is connected by a connecting shaft cylinder 5, a driving component is provided inside the connecting part 2, a push block 9 is movably provided on the outer side of the calf bracket 3, a movable hole 10 is provided on the calf bracket 3, and the push block 9 is used in conjunction with the driving member through the connecting rod assembly to drive the top pressing component;

[0037] One side of the calf bracket 3 is inserted with a cover cylinder 4, and the cover cylinder 4 plays a role in wrapping and protecting the caregiver's leg. Among them, the auxiliary rehabilitation drugs can be attached to the inner side of the calf bracket 3 or the cover cylinder 4, provided that the ejector rod 25 at one end of the mounting disc 12 is not blocked, and the drugs do not need to be attached to the skin hitting area, so that the hitting end of the ejector rod 25 contacts the patient's skin;

[0038] It should be noted that the bottom of the thigh bracket 1 can be connected to the connecting shaft cylinder 5 through a connecting bracket, and the connecting shaft cylinder 5 and the thigh bracket 1 are always in a static state relative to the connecting part 2.

[0039] Specifically, the pressing component includes a second mounting groove 23, a telescopic hole 24, an ejector rod 25, and a return spring 26. The second mounting groove 23 is opened on one side of the annular mounting disc 12, the telescopic holes 24 are equidistantly opened on the side wall of the second mounting groove 23, the ejector rod 25 is movably arranged inside the telescopic hole 24, and the return spring 26 is sleeved outside the ejector rod 25.

[0040] In this implementation scheme, the pressing component is set to strike and massage the muscles around the calf bone, so as to promote blood circulation. The massage can increase the blood flow of the muscles and surrounding soft tissues, and may indirectly improve the blood supply of the fracture site, providing more oxygen and nutrients for bone healing;

[0041] Through the periodic striking of the muscles by the ejector rod 25, muscle tension can be relieved, abnormal traction on the fracture site can be reduced, and a more stable environment can be created for bone healing.

[0042] The following is a detailed description of the drive of the pressing component. The push block 9 is driven by the connecting rod component to perform reciprocating motion at the upper and lower ends along the arched side of the calf bracket 3. Since a U-shaped groove 21 is opened on one side of the push block 9, inclined surfaces 22 are symmetrically opened at both ends of the push block 9, and the push block 9 is arranged in contact with the pressing component. The inclined surface 22 squeezes the rounded end of the ejector rod 25 and performs step-by-step squeezing inside the U-shaped groove 21, so that the other end of the ejector rod 25 squeezes the leg muscles. During the squeezing process, the ejector rod 25 squeezes and compresses the return spring 26 to store a certain amount of elastic potential energy. When the squeezing of the ejector rod 25 by the push block 9 disappears, the ejector rod 25 resets under the action of the elastic potential energy of the return spring 26. Therefore, the squeezing and massaging of the muscles by the ejector rod 25 rely on the reciprocating motion of the push block 9 to achieve continuous periodic massage. The ejector rod 25 is arranged in a straight line along the mounting disc 12, and the number of ejector rods 25 can be selectively set according to the density of massage squeezing.

[0043] Specifically, one end of the return spring 26 is fixedly connected to the inner wall of the second mounting groove 23, and the other end is provided with a limiting collar. The diameter of the collar is larger than that of the ejector rod 25 and the telescopic hole 24. The initial state of the return spring 26 is the original length state, and rounded corners are opened at both ends of the ejector rod 25.

[0044] In this embodiment, a reset spring 26 is provided to reset the push rod 25. When the squeezing of the push block 9 on the push rod 25 disappears, the push rod 25 is reset to its original length under the action of the elastic potential energy of the reset spring 26. A limiting ring provided at one end of the reset spring 26 is fixedly mounted on the push rod 25. The limiting ring is used to limit the push rod 25 to prevent the push rod 25 from detaching from the telescopic hole 24 when squeezed by the push block 9.

[0045] Specifically, the driving component includes a mounting groove 16, a driving disk 18, and a toggle tooth 20. The mounting groove 16 is opened in the middle of the connecting part 2, the driving disk 18 is fixedly installed on the inner protrusion of the mounting groove 16, and the toggle tooth 20 is symmetrically arranged on one side of the driving disk 18.

[0046] In this embodiment, a mounting groove 16 is provided for mounting the components in the driving component, and a driving disk 18 is fixedly mounted on the inner protrusion of the mounting groove 16. The driving disk 18 is driven to rotate by deflecting the connecting portion 2, wherein the driving force of the connecting portion 2 comes from the bending and lifting of the leg. When the driving disk 18 rotates, the toggle tooth 20 is driven to rotate together, and when the toggle tooth 20 is driven to rotate, the toothed disk 19 is driven to rotate, thereby realizing the driving connection assembly to push the push block 9.

[0047] Specifically, the driving component also includes a shaft seat 28, a torsion spring 29, and a tooth groove 30. The shaft seat 28 is fixedly installed on one side of the driving disk 18. The torsion spring 29 is fixedly arranged with the shaft seat 28 and the toggle tooth 20 through the connecting shaft. The tooth groove 30 is opened at one end of the toggle tooth 20.

[0048] In this embodiment, an axle seat 28 is provided to install the toggle tooth 20, and the axle seat 28 is connected by a short shaft. A torsion spring 29 is provided on the short shaft to reset the toggle tooth 20. The tooth groove 30 at one end of the toggle tooth 20 is meshed with the helical tooth 27. When the toggle tooth 20 follows the drive disk 18 to rotate clockwise, the drive disk 18 rotates clockwise due to the clockwise rotation of the connecting part 2. At this time, the leg is performing a lifting movement, and the toggle tooth 20 will mesh with the helical tooth 27 on one side of the toothed disk 19 and drive the toothed disk 19, thereby driving the toothed disk 19 to rotate to drive the connecting component. When the leg performs a falling and bending movement, the connecting part 2 rotates counterclockwise. At this time, the toggle tooth 20 on one side of the drive disk 18 is in contact with the helical tooth 27 under the action of the torsion spring 29, and is in a non-meshing state, and the toothed disk 19 will not be driven.

[0049] Specifically, the connecting rod assembly includes a rotating disk 7 and a Z-shaped connecting rod 8. The rotating disk 7 is fixedly connected to the driving component. One end of the Z-shaped connecting rod 8 is movably connected to the rotating disk 7 through a convex shaft, and the other end of the Z-shaped connecting rod 8 is movably connected to the movable hole 10.

[0050] A long shaft is movably installed inside the connecting shaft cylinder 5, and a toothed disc 19 is fixedly installed on the outside of the long shaft. The toothed disc 19 is provided with helical teeth 27 on the side close to the driving component. The toothed disc 19 is arranged parallel to the driving component, and one end of the long shaft is fixedly connected to the connecting rod assembly.

[0051] The helical teeth 27 provided on the toothed disc 19 are meshed with the driving component.

[0052] In this embodiment, a rotating disk 7 and a Z-shaped connecting rod 8 are provided to convert the circular motion of the toothed disk 19 into a linear reciprocating motion, thereby realizing the reciprocating pushing of the push block 9;

[0053] The driving disc 18 fixed on the inner protrusion of the mounting groove 16 is arranged parallel to the toothed disc 19 , so when the driving disc 18 rotates clockwise, it drives the shifting teeth 20 to engage with the bevel teeth 27 , thereby driving the toothed disc 19 .

[0054] Specifically, a protective cover 15 is buckled on one side of the connecting portion 2 , a circular hole is opened on the surface of the protective cover 15 , and the driving component is arranged through the circular hole.

[0055] In this embodiment, a protective cover 15 is provided on one side of the connecting portion 2 to protect the mounting groove 16 and the driving components.

[0056] When in use, the caregiver places the thigh on the groove 13 at the top of the thigh bracket 1, and the calf on the inner side of the calf bracket 3, and then uses the cover tube 4 to clamp the calf bracket 3 to form a sleeve, wherein the calf bracket 3 and the cover tube 4 can be connected by adhesive tape or screw fixation to achieve the connection between the cover tube 4 and the calf bracket 3. At this time, the caregiver presses the thigh and lifts the calf up and down. At this time, the connecting part 2 makes a circular deflection motion, wherein when the calf is lifted, the connecting part 2 rotates clockwise, and the connecting part 2 deflects The driving disk 18 is driven to rotate, and when the driving disk 18 rotates, the toggle tooth 20 is driven to rotate together, and when the toggle tooth 20 rotates, the toothed disk 19 is driven to rotate, so that the driving connection component can push the push block 9, and the push block 9 squeezes the push rod 25 provided on the inner side of the mounting disk 12, so that one end of the push rod 25 hits the leg muscles to promote blood circulation. Massage can increase the blood flow of muscles and surrounding soft tissues, which may indirectly improve the blood supply to the fracture site and provide more oxygen and nutrients for bone healing.
