[0025] like Figure 1-5 As shown, a hemiplegic limb straightening chair includes a seat 100 and a backrest 101. A C-shaped pillow support 102 is installed on the outer surface of the backrest 101 through a first height adjustment mechanism 200. Two semi-circular neck supports 103 are respectively installed on the outer surface of the backrest 101 through a second height adjustment mechanism 300, and the two semi-circular neck supports 103 are combined to form a C-shaped structure. Telescopic upper limb supports 104 are provided on both outer surfaces of the backrest 101. Two lower limb supports 105 are installed on the front side of the seat 100. The outer surface of the lower limb supports 105 is provided with a recessed part. A foot pedal 106 is installed at the end of the lower limb supports 105. A lumbar support pillow 107 is provided on the surface of the backrest 101.

[0026] In use, the height of the C-shaped pillow support 102 and the semi-circular neck support 103 are first adjusted according to the patient's height using the first height adjustment mechanism 200 and the second height adjustment mechanism 300. When the patient sits on the seat board 100, the head rests on the C-shaped pillow support 102 and the neck is supported by the two semi-circular neck supports 103. The C-shaped pillow support 102 can fix the head, while the two semi-circular neck supports 103 can fix the neck, thus compensating for the problem of unstable head fixation in hemiplegic patients. Next, the hands are placed on the telescopic upper limb support 104 and the legs are placed on the lower limb support 105. The concave part can position the lower leg, preventing displacement of the affected limb and replacing the discomfort of traditional straps. The footrest 106 supports the soles of the feet, thus maintaining the patient's normal sitting position and facilitating the patient's eating or feeding by the caregiver. The lumbar support pillow 107 provides support for the patient's waist and is made of slow rebound material, which is highly comfortable.

[0027] Furthermore, the telescopic upper limb support 104 facilitates the placement of the patient's arm when it is bent. The telescopic upper limb support 104 includes a fixed housing and a movable support for telescopic movement. The movable support is slidably installed inside the fixed housing and fixed by screws on the outside.

[0028] Specifically, the first height adjustment mechanism 200 includes two first through slots 201 formed on the surface of the backrest 101. A U-shaped plate 202 is provided inside the two first through slots 201, and both ends of the U-shaped plate 202 are connected to the outer surface of the C-shaped pillow support 102. A first bolt 203 is installed inside the horizontal plate of the U-shaped plate 202. When it is necessary to adjust the height of the C-shaped pillow support 102, the first bolt 203 can be loosened first, at which point the U-shaped plate 202 is released from fixation. Then, it can be slid up and down to adjust the height. After the height is adjusted, the first bolt 203 is tightened so that its end is pressed against the surface of the backrest 101, thereby fixing the C-shaped pillow support 102.

[0029] Specifically, the second height adjustment mechanism 300 includes a second through groove 301 formed on the surface of the backrest 101, an mounting plate 302 installed on the outer surface of the semi-circular neck support 103, a connecting plate 303 provided on the outer surface of the mounting plate 302, the end of the connecting plate 303 extending through the second through groove 301 to the rear side of the backrest 101, and fixing blocks 304 installed on the rear side of the backrest 101 and on both the upper and lower sides of the second through groove 301, and a screw 305 rotatably connected between the two fixing blocks 304, and the screw 305 passes through the interior of the connecting plate 303 and is threadedly connected to it. When it is necessary to adjust the height of the semi-circular neck support 103, the screw 305 can be turned. Since the second through groove 301 plays a limiting role on the connecting plate 303, the height of the semi-circular neck support 103 can be adjusted through the connecting plate 303 and the mounting plate 302 under the drive of the threaded connection.

[0030] Specifically, a groove 400 is provided on the rear side of the mounting plate 302, and a slider 401 is provided inside the groove 400. The connecting plate 303 is installed on the outer surface of the slider 401, and a first screw hole 402 is provided on the outer surface of the slider 401. A third through groove 403 is provided on the front side of the mounting plate 302, and a third bolt 404 is provided inside the third through groove 403. The third bolt 404 matches the first screw hole 402. By loosening the third bolt 404 from the first screw hole 402, its end is separated from the surface of the mounting plate 302. At this time, the position of the semi-circular neck brace 103 can be adjusted by sliding the mounting plate 302 horizontally. After the horizontal position of the semi-circular neck brace 103 is adjusted, the third bolt 404 is tightened again so that its end is pressed against the surface of the mounting plate 302, thereby fixing the position of the semi-circular neck brace 103. Therefore, by appropriately adjusting the distance between the two semi-circular neck braces 103, it can be used by patients with necks of different thicknesses. When the semi-circular neck brace 103 is not needed, it can be moved to the side without affecting the use of the C-shaped pillow support 102.

[0031] Specifically, the backrest 101 has connecting grooves 500 on both sides. The telescopic upper limb support 104 has a pin 501 installed at its end, and the pin 501 is located in the connecting groove 500. The outer surface of the pin 501 has two second screw holes 502, and the included angle between the two second screw holes 502 is 90 degrees. The rear side of the backrest 101 is equipped with a fourth bolt 503 that matches the second screw holes 502. Through the setting of the connecting grooves 500 and the pin 501, the telescopic upper limb support 104 has the ability to flip. By screwing the fourth bolt 503 into the two second screw holes 502 respectively, the telescopic upper limb support 104 can be fixed in a horizontal or vertical state. Therefore, when the telescopic upper limb support 104 is not in use, it can be flipped and fixed in a vertical state to meet the usage needs in different situations.

[0032] Specifically, the outer surface of the backrest 101 is provided with Velcro strips 600, and the lumbar support pillow 107 is attached to the Velcro strips 600. By attaching the Velcro strips 600 to the lumbar support pillow 107, the position of the lumbar support pillow 107 can be adjusted so that it fits the patient's waist better and is more comfortable.

[0033] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
