Description

Technical Field

[0001] This utility model relates to the field of foot orthosis technology, and specifically discloses a positioning bed foot orthosis. Background Technology

[0002] Foot deformities caused by limb impairment are a common disease in hemiplegic patients. Currently, foot deformities are usually corrected by orthotics.

[0003] Currently, most bed foot orthoses used in clinical practice employ a rigid fixation method, with their structure typically fastened directly to the bed surface using bolts or clips. This type of device has significant drawbacks in practical use:

[0004] When a patient's foot is immobilized by an orthosis, the rigid connection between the orthosis and the bed surface completely deprives the patient's foot of any space for independent movement. Prolonged immobilization can lead to impaired blood circulation in the foot joints due to lack of necessary movement, resulting in complications such as muscle stiffness and joint pain in the lower limbs. This is especially problematic for patients requiring long-term bed rest. Such complete immobilization can cause not only local discomfort in the foot and ankle but may also lead to compensatory strain on the knee joint through biomechanical transmission, and even affect the physiological curvature of the lumbar spine. Existing solutions often require patients to frequently remove the immobilization device for intermittent movement. However, this repeated disassembly and reassembly increases the difficulty of care and may affect the orthotic treatment effect due to changes in body position. Furthermore, traditional orthoses lack a dynamic adjustment mechanism for their fixation angle, making it difficult to adapt to the varying needs of patients at different stages of rehabilitation. Utility Model Content

[0005] This utility model proposes a positioning foot orthosis for beds. By connecting the heel fixation strap and the foot elastic strap to the inside of a square frame, the orthosis body can move slightly inside the square frame, realizing a dynamic orthotic mode of "rigid fixation as the main feature and elastic movement as the auxiliary feature", which can alleviate the muscle stiffness and joint pain caused by traditional fully fixed orthotics.

[0006] This utility model is implemented as follows: a positioning foot orthosis for beds, comprising:

[0007] The foot orthosis body includes a fixed sole, and a leg fixing sleeve is fixedly connected to the heel of the fixed sole;

[0008] A square frame has two guide holes at its top. The foot orthosis body is located in the center of the inner side of the square frame. Fixing straps are fixedly connected to the two bottom corners of the inner side of the square frame. The other ends of the two fixing straps are fixedly connected to the bottom of the heel of the foot orthosis body. Two elastic straps are fixedly connected to the top of the sole of the foot orthosis body. Retracting rollers are provided on the upper left and right sides of the outer wall of the square frame. The other ends of the two elastic straps pass through the guide holes through the top of the square frame and are respectively wrapped around the outer wall of the two retracting rollers.

[0009] Fixed structure.

[0010] As a preferred embodiment of the positioning foot orthosis in bed according to this utility model, the fixing mechanism includes a fixing base with a "C" shaped cross-section. The fixing base is fixedly connected to the bottom of a square frame. Two threaded rods are threadedly connected to the bottom of the fixing base, and a fixing seat is fixedly connected to the top of each of the two threaded rods.

[0011] As a preferred embodiment of the positioning foot orthosis for beds of this utility model, the outer wall of the take-up roller is provided with a crank handle for driving the take-up roller to rotate, the outer wall of the crank handle is fixedly connected with a ratchet, and the outer wall of the take-up roller is rotatably connected with a pawl that meshes with the ratchet.

[0012] As a preferred embodiment of the positioning foot orthosis for beds according to this utility model, the fixed shoe sole and the leg fixing sleeve are made of the same material and both include a base layer. The inner side of the base layer is provided with a rubber layer, and the outer wall of the base layer and the rubber layer is covered with a soft layer.

[0013] As a preferred embodiment of this utility model, the outer walls of the leg fixing sleeve and the fixing shoe sole are respectively provided with leg straps and foot straps.

[0014] As a preferred embodiment of the positioning foot orthosis in bed according to this utility model, guide wheels are provided on the top left and right sides of the square frame, and the two elastic bands pass through the outer walls of the two guide wheels respectively.

[0015] As a preferred embodiment of this utility model, the fixing strap is made of non-elastic fabric.

[0016] The beneficial effects of this utility model are:

[0017] This invention connects the foot orthosis to the inside of a square frame via a fixing strap at the heel and an elastic strap at the forefoot. This allows the orthosis to move slightly within the frame. A crank handle drives a winding roller to rotate, adjusting the stretch of the elastic strap. As the strap tightens, its elasticity gradually decreases, controlling the range of motion of the orthosis within the frame, such as slight foot lifting or inversion. This achieves a dynamic orthotic mode that prioritizes rigid fixation while allowing for elastic movement. This promotes blood circulation, alleviates muscle stiffness and joint pain caused by traditional fully fixed orthoses, and provides superior comfort and ease of use. Attached Figure Description

Detailed Implementation

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] Please see Figure 1-4A positioning foot orthosis for beds, comprising:

[0027] The foot orthosis body 1 includes a fixed sole 2, and a leg fixing sleeve 3 is fixedly connected to the heel of the fixed sole 2.

[0028] A square frame 4 has two guide holes 17 at its top. The foot orthosis body 1 is located in the center of the inner side of the square frame 4. Fixing straps 5 are fixedly connected to the two bottom corners of the inner side of the square frame 4. The other ends of the two fixing straps 5 are fixedly connected to the bottom of the heel of the foot orthosis body 1. Two elastic straps 6 are fixedly connected to the top of the foot of the foot orthosis body 1. There are take-up rollers 7 on the upper left and right sides of the outer wall of the square frame 4. The other ends of the two elastic straps 6 pass through the guide holes 17 through the top of the square frame 4 and are respectively wrapped around the outer wall of the two take-up rollers 7.

[0029] Fixed structure.

[0030] In this embodiment, the foot orthosis body 1 is connected to the inside of the square frame 4 via a fixing strap 5 at the heel and an elastic strap 6 at the forefoot, allowing the foot orthosis body 1 to move slightly inside the square frame 4. The elastic strap 6 at the top of the forefoot passes through the guide hole 17 or guide wheel 8 at the top of the square frame 4 and is wound around the two take-up rollers 7 on both sides. The take-up rollers 7 are rotated by the crank handle 12, which can adjust the stretch length of the elastic strap 6. After the elastic strap 6 is tightened, its elasticity gradually decreases, thereby controlling the range of motion of the foot orthosis body 1 within the square frame 4, such as slight lifting or inversion of the foot. This achieves a dynamic orthotic mode of "rigid fixation as the main feature and elastic movement as the auxiliary feature", which facilitates blood circulation and alleviates muscle stiffness and joint pain caused by traditional fully fixed orthoses. It is highly comfortable and easy to use.

[0031] As a technical optimization of this utility model, the fixing mechanism includes a fixing base 9 with a "C" shaped cross section. The fixing base 9 is fixedly connected to the bottom of the square frame 4. Two threaded rods 10 are threadedly connected through the bottom of the fixing base 9, and a fixing seat 11 is fixedly connected to the top of each of the two threaded rods 10.

[0032] In this embodiment, the fixed base 9 has a "C" shaped cross section. When fixing, the fixed base 9 is placed on the bed board, and then the two threaded rods 10 are turned to drive the fixed seat 11 to abut against the bed board and fix it, which facilitates the overall installation of the equipment.

[0033] As a technical optimization of this utility model, the outer wall of the take-up roller 7 is provided with a rocker arm 12 for driving the take-up roller 7 to rotate. A ratchet wheel 13 is fixedly connected to the outer wall of the rocker arm 12, and a pawl 14 that meshes with the ratchet wheel 13 is rotatably connected to the outer wall of the take-up roller 7.

[0034] In this embodiment, the ratchet 13 and pawl 14 facilitate self-locking, ensuring reliable length locking of the elastic band 6 and preventing accidental loosening of the orthosis due to patient movement.

[0035] As a technical optimization of this utility model, the fixed shoe sole 2 and the leg fixing sleeve 3 are made of the same material and both include a base layer 18. A rubber layer 19 is provided on the inner side of the base layer 18, and a soft layer 20 is covered on the outer wall of the base layer 18 and the rubber layer 19.

[0036] In this embodiment: the base layer 18 is made of rigid plastic, which serves as the basic shaping element; the rubber layer 19 provides a cushioning effect; and the soft layer 20 comes into contact with the skin, dispersing pressure and reducing the risk of local pressure sores.

[0037] As a technical optimization of this utility model, the outer walls of the leg fixing sleeve 3 and the fixing shoe sole 2 are respectively provided with leg straps 15 and foot straps 16.

[0038] In this embodiment, the leg strap 15 and the foot strap 16 are used to bind and fix the patient's legs and feet, respectively.

[0039] As a technical optimization of this utility model, guide wheels 8 are provided on the top left and right sides of the square frame 4, and two elastic bands 6 pass through the outer walls of the two guide wheels 8 respectively.

[0040] In this embodiment, the guide wheel 8 guides the elastic belt 6, making the winding of the elastic belt 6 more stable and smooth.

[0041] As a technical optimization of this utility model, the fixing strap 5 is woven from non-elastic fabric.

[0042] In this embodiment: the fixing strap 5 is woven from inelastic fabric and has no elasticity itself, thereby restricting the horizontal position of the foot orthosis body 1 and preventing the foot orthosis body 1 from having too large a range of motion.

[0043] The working principle and usage process of this utility model: The foot orthosis body 1 is connected to the inside of the square frame 4 through the fixing strap 5 at the heel and the elastic strap 6 at the forefoot, allowing the foot orthosis body 1 to move slightly inside the square frame 4. The elastic strap 6 at the top of the forefoot passes through the guide hole 17 or guide wheel 8 at the top of the square frame 4 and is wound around the two side take-up rollers 7. The take-up rollers 7 are driven to rotate by the crank handle 12, which can adjust the stretching length of the elastic strap 6. After the elastic strap 6 is tightened, its own elasticity gradually decreases, thereby controlling the range of motion of the foot orthosis body 1 within the square frame 4, such as slight lifting or inversion of the foot, realizing a dynamic orthotic mode of "rigid fixation as the main function and elastic movement as the auxiliary function", which is conducive to promoting blood circulation and relieving muscle stiffness and joint pain caused by traditional fully fixed orthoses. It is highly comfortable and easy to use.
