Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a body position assistance device for stroke patients, including a forearm support frame 1, a wrist support frame 2, an arc electromagnet generator 3, a bogie 4, a first restraint belt 5, a first silicone pad 6, a telescopic belt 7, a second silicone pad 8, an upper limb connecting frame 9, a positioning frame 10, a buffer pad 11, a second restraint belt 12, a limit ratchet 13, a limit component 14, a positioning slide rail 1401, a push slide rod 1402, a limit lock block 1403, and a protective frame 15;

[0045] Among them, the forearm support frame 1 is set as a strip-shaped frame structure. One side of the forearm support frame 1 is slidably connected to the wrist support frame 2, and the other side of the forearm support frame 1 is rotatably connected to the upper limb connecting frame 9. Moreover, the forearm support frame 1, the wrist support frame 2, and the upper limb connecting frame 9 constitute the main structure of the patient's upper limb position assistance device;

[0046] A strip-shaped block is installed on one side of the wrist support frame 2, and the strip-shaped block of the wrist support frame 2 is slidably connected to the forearm support frame 1. An arc-shaped electromagnet generator 3 is installed inside the wrist support frame 2, and the magnetic generating part of the arc-shaped electromagnet generator 3 is set to be arc-shaped. The arc-shaped electromagnet generator 3 is composed of a C-shaped metal plate and a generator, and the C-shaped metal plate of the arc-shaped electromagnet generator 3 is in contact with the coil of the generator. One end of the C-shaped metal plate of the arc-shaped electromagnet generator 3 is rotatably connected to the bogie 4, and the center of the rotating shaft of the bogie 4 is aligned with the center of the C-shaped metal plate of the arc-shaped electromagnet generator 3. The connection between the forearm support frame 1 and the upper limb connection frame 9 is set as a U-shaped bracket structure, and the shaft rod of the U-shaped bracket of the forearm support frame 1 is connected to both ends of the limiting ratchet 13, and the shaft rod of the limiting ratchet 13 is rotatably connected to the positioning frame 10. The other side of the wrist support frame 2 is rotatably connected to the bogie 4, and a through hole is provided inside the bogie 4, and a first restraint belt 5 is installed in the through hole of the bogie 4. A rotating shaft is provided at the rotation part of the bogie 4 and the wrist support frame 2. A first silica gel pad 6 is snap-connected to the upper end of the wrist support frame 2, and a telescopic belt 7 is installed on the surface of the strip-shaped block of the wrist support frame 2. Both sides of the telescopic belt 7 are abutted against the first silica gel pad 6 and the second silica gel pad 8 respectively, and the second silica gel pad 8 is installed on the surface of the forearm support frame 1;

[0047] As shown in the accompanying drawings of the specification Figures 1 - 10 shown, clean each part of the device, especially the parts in contact with the patient's skin, with a mild cleaner and clean water. After each use, wipe the surface of each part of the device with a clean damp cloth to remove dust, stains and sweat stains. For the first silica gel pad 6, the second silica gel pad 8 and the buffer pad 11, wash them with a mild detergent and then rinse them with clean water and dry them naturally, avoiding exposure to the sun to prevent material aging. By pulling the forearm support frame 1 and the wrist support frame 2 to adjust the length between them, the first silica gel pad 6, the telescopic belt 7 and the second silica gel pad 8 are sequentially covered on the surfaces of the forearm support frame 1 and the wrist support frame 2, as Figures 1 - 3 shown, when the device is in use, adjust the position of the device according to the patient's posture. Pick up the first restraint belt 5, pass its C-shaped structure through the hole of the bogie 4, and then wrap it around the patient's wrist. Adjust the tightness of the first restraint belt 5 according to the thickness of the patient's wrist so that it can fix the wrist without causing compression. Fix the first restraint belt 5 with a magic tape. Then, wrap the second restraint belt 12 around the patient's upper arm and fix it at the buffer pad 11. Similarly, adjust the tightness so that the patient's upper arm is stable on the device. The patient's upper limb is initially positioned on the auxiliary device by the restraint belts. The wrist support frame 2, the forearm support frame 1 and the upper limb connection frame 9 start to provide basic support for the upper limb, as Figure 1 shown;

[0048] During the whole operation process, pay attention to observing the patient's reaction, adjust the comfort of the device according to the patient's feeling. If the patient feels a sense of pressure on the wrist or upper arm, the restraint belt can be loosened appropriately for fine adjustment. Check whether the stretch belt 7 installed on the surface of the strip-shaped block of the wrist support frame 2 is in close contact with the silica gel pad one 6 and the silica gel pad two 8. When the stretch belt 7 is displaced or loose, manually adjust its position to ensure that when the wrist support frame 2 slides and adjusts, the stretch belt 7 can adaptively deform and always be in close contact with the silica gel pads on both sides, further improving the fitting degree and comfort of the patient's wearing;

[0049] The positioning frame 10 is installed on the surface of the upper limb connecting frame 9. A C-shaped plate body is arranged on one side of the upper limb connecting frame 9. One end of the protective frame 15 is installed on the upper end surface of the positioning frame 10. The upper end of the upper limb connecting frame 9 is snap-connected with a buffer pad 11. A second restraint belt 12 and a first restraint belt 5 are both arranged in a ring structure. The second restraint belt 12 is composed of a C-shaped silica gel plate and a restraint belt. The protective frame 15 is arranged as a C-shaped frame body and slides through the forearm support frame 1. The protective frame 15 surrounds the outside of the limit ratchet 13 and is arranged above the inner part of the C-shaped plate body of the upper limb connecting frame 9. The C-shaped plate body of the upper limb connecting frame 9 is below the limit ratchet 13. One end of the upper limb connecting frame 9 is connected to the bottom end of the forearm support frame 1. The triangular teeth on the surface of the limit ratchet 13 are arranged in a ring, and the triangular teeth of the limit ratchet 13 are equidistantly arranged. There are gaps between the triangular teeth on the surface of the limit ratchet 13. A limit component 14 is arranged on one side of the limit ratchet 13 and penetrates through the forearm support frame 1. The limit component 14 includes a positioning slide rail 1401, a push slide rod 1402 and a limit lock block 1403. The positioning slide rail 1401 is installed on the inner wall surface of the opening of the positioning frame 10. The push slide rod 1402 is slidably connected in the positioning slide rail 1401. A spring is arranged at the other end of the push slide rod 1402, and the spring of the push slide rod 1402 is connected to the inner wall of the positioning frame 10. Rectangular openings are equidistantly arranged in the push slide rod 1402. The limit lock block 1403 is connected to the rectangular openings in the push slide rod 1402 through a spring and abuts against the teeth of the limit ratchet 13;

[0050] Combined with the attached drawings of the specification Figures 1 - 10As shown, after the restraint strap one 5 and the restraint strap two 12 restrict the patient's upper arm and forearm, the medical staff holds the patient's upper arm with one hand and restricts the position of the upper arm bound by the restraint strap two 12. With the other hand, the medical staff slowly pulls the patient's curled forearm, causing the forearm support frame 1 and the upper limb connecting frame 9 to rotate around the shaft rod of the limit ratchet 13, thereby adjusting the angle between the forearm and the upper arm. During the adjustment process, the limit ratchet 13 rotates accordingly. When the appropriate angle for the patient's upper arm and forearm to be flattened is reached, the limit lock block 1403 inside the push rod 1402 automatically abuts against the triangular tooth block of the limit ratchet 13 under the action of the spring, restricting the position of the limit ratchet 13 and preventing it from flipping, thereby firmly locking the angle between the forearm and the upper arm, keeping the patient's upper limb in an elbow-restrained state and meeting the body position requirements for rehabilitation treatment. When the treatment or rehabilitation work is completed and the angle needs to be reset, the medical staff pushes the push rod 1402 on one side of the positioning frame 10, causing the limit lock block 1403 to be misaligned with the tooth block of the limit ratchet 13. At this time, the forearm support frame 1 and the upper limb connecting frame 9 can rotate freely and return to the initial position for the next angle adjustment;

[0051] After the positions of the patient's upper arm and forearm are flattened and fixed, when adjusting the angle of the patient's pronated wrist during use, the steering frame 4 rotates around the rotating shaft, driving the patient's wrist to adjust the angle. At the same time, according to the needs of rehabilitation treatment, the power supply of the arc-shaped electromagnet generator 3 is turned on. After the C-shaped metal plate of the generator contacts the generator coil and is energized, an arc-shaped magnetic field is generated, generating an adsorption force on the metal rod arranged on one side of the steering frame 4. The metal rod is shown at the cross-section of the Figure 2 steering frame 4, so as to keep the wrist restricted on the steering frame 4 fixed, as shown in Figure 6 and Figure 7 shown. Since the center of the rotating shaft of the steering frame 4 is aligned with the center of the C-shaped metal plate of the arc-shaped electromagnet generator 3, the accuracy of the magnetic field action is ensured, and the position and angle of the wrist are stably fixed. The power supply of the arc-shaped electromagnet generator 3 uses an internal battery for power supply, and its switch is installed on the outside of the arc-shaped electromagnet generator 3. A wiring port connected to the ward power supply is arranged on one side of the arc-shaped electromagnet generator 3. During the daily maintenance of the device, regularly check whether the circuit connection of the arc-shaped electromagnet generator 3 is normal to ensure that the magnetic field can be generated normally after being energized.

[0052] Working principle: When using this body position assistance device for stroke patients, first, the patient places the upper limb on this body position assistance device. The C-shaped structure of the restraint strap one 5 passes through the hole of the steering frame 4. As the strap of the restraint strap one 5 wraps around the wrist, the restraint strap two 12 wraps around the patient's upper arm and is fixed at the buffer pad 11. The annular restraint strap can initially position the upper limb, making the patient's upper limb stable on the assistance device and laying the foundation for subsequent body position adjustment. At this time, the main structure composed of the wrist support frame 2, the forearm support frame 1, and the upper limb connecting frame 9 provides basic support for the patient's upper limb;

[0053] When the wrist support frame 2 and the upper limb connecting frame 9 are bound to the patient's upper limb wrist and upper arm, by pulling the strip-shaped block on one side of the wrist support frame 2 and slidingly connecting it with the forearm support frame 1, it can be adjusted according to the patient's forearm length requirements. When assisting the patient in adjusting the body position, by restricting the position of the patient's upper arm bound by the second restraint strap 12 and pulling the patient's curled forearm, the forearm support frame 1 and the upper limb connecting frame 9 rotate. Since the forearm support frame 1 and the upper limb connecting frame 9 are connected by a U-shaped support structure to the shaft rods at both ends of the limit ratchet 13 and can rotate relative to each other, the angle between the forearm and the upper arm can be adjusted. When the limit lock block 1403 inside the push rod 1402 abuts against the triangular teeth of the limit ratchet 13, the position of the limit ratchet 13 is restricted to prevent the limit ratchet 13 from flipping, thereby firmly locking the angle between the forearm and the upper arm and keeping the patient's upper limb in an elbow-restrained state. When resetting, by pressing the push rod 1402, the limit lock block 1403 is misaligned with the teeth of the limit ratchet 13, thereby realizing the reset of the forearm support frame 1 and the upper limb connecting frame 9;

[0054] The bogie 4 rotatably connected to the other side of the wrist support frame 2 can rotate around the rotating shaft to realize fine adjustment of the wrist angle. The arc-shaped electromagnetic generator 3 inside the wrist support frame 2 plays a role. After its C-shaped metal plate contacts the generator coil and is energized, an arc-shaped magnetic field is generated, which can adsorb the metal rod provided on one side of the bogie 4, so that the wrist restricted on the bogie 4 is kept fixed. Among them, the center of the rotating shaft of the bogie 4 is aligned with the center of the C-shaped metal plate of the arc-shaped electromagnetic generator 3 to ensure the accuracy of the magnetic field action and realize the stable fixation of the wrist position and angle;

[0055] The first silica gel pad 6 at the upper end of the wrist support frame 2, the second silica gel pad 8 on the surface of the forearm support frame 1, and the buffer pad 11 at the upper end of the upper limb connecting frame 9 are in contact with the patient's limb. The silica gel pad and the buffer pad 11 are made of soft materials, which can reduce the friction and pressure with the skin. The telescopic belt 7 installed on the surface of the strip-shaped block of the wrist support frame 2 deforms adaptively when the wrist support frame 2 slides and adjusts, and always abuts against the first silica gel pad 6 and the second silica gel pad 8, further improving the fitting degree and comfort of the patient's wearing.

[0056] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
