Description

Technical Field

[0001] This utility model relates to the field of lower limb exercise technology, and in particular to a lower limb exercise device for orthopedic care. Background Technology

[0002] Orthopedic nursing is an important branch of nursing, mainly providing professional nursing services for patients with orthopedic diseases, covering the entire process from patient admission to rehabilitation and discharge. Lower limb exercises are an important part of orthopedic nursing work. Through lower limb exercises, the strength of the muscles around the joints can be enhanced, the stability and flexibility of the joints can be improved, and the recovery of joint function can be promoted.

[0003] Publication number CN215387364U discloses a lower limb exercise device for orthopedic care, relating to the field of medical device technology. The device includes a seat with two L-shaped footrests rotatably mounted on the right end of the seat. Each L-shaped footrest has a footrest support block on its bottom right side, with a groove within the block. An electrically operated telescopic rod, parallel to the seat, is located on the left side below the seat. The telescopic rod is fixedly connected to the seat via a mounting plate. A connecting plate is located at the right end of the telescopic rod, with springs connected to the two L-shaped footrests on its front and rear sides. A switch for controlling the telescopic rod is located on the armrest. This exercise device retracts the two L-shaped footrests downwards from the seat by extending the telescopic rod, facilitating lower limb exercise for the patient.

[0004] The above-mentioned exercise device has the following drawbacks: the device exercises the lower limbs by swinging the legs, but during the leg swinging process, it can only repeatedly bend the knee joint, and the exercise effect on the ankle and hip joints is poor.

[0005] Therefore, a lower limb exercise device for orthopedic care is proposed. Utility Model Content

[0026] Reference Figures 1-4 As an embodiment of the present invention, a lower limb exercise device for orthopedic care is provided, which includes a housing 1 and a pneumatic lifting chair 2 fixedly connected to the top of the housing 1.

[0027] A reciprocating lead screw 3 is rotatably mounted inside the housing 1. A drive motor 4, which drives the reciprocating lead screw 3 to rotate, is fixed inside the housing 1. A lead screw nut 5, which is threadedly connected to the reciprocating lead screw 3, is also slidably connected inside the housing 1. When the reciprocating lead screw 3 rotates, the lead screw nut 5 slides back and forth along the front of the pneumatic lifting chair 2. Figure 2 and Figure 3 As shown, horizontally arranged guide rails are fixedly connected to both sides of the lead screw nut 5 inside the housing 1. Horizontal sliding grooves are opened on both sides of the lead screw nut 5 to cooperate with the guide rails. The lead screw nut 5 is slidably connected to the housing 1 through the cooperation of the guide rails and sliding grooves.

[0028] Inside the housing 1, exercise components 6 are mirror-arranged on both sides of the lead screw nut 5. Each exercise component 6 includes a drive strip 61 fixedly connected to the housing 1, an "L"-shaped plate 62 slidably connected to the lead screw nut 5 in the vertical direction, a connecting plate 63 fixedly connected to the top of the "L"-shaped plate 62, a foot restraint frame 64 located on the outside of the housing 1 and fixedly connected to the top of the connecting plate 63, and a drive rod 65 fixedly connected to the side of the "L"-shaped plate 62 near the drive strip 61. A wave groove 61a is provided on the drive strip 61 along the front of the pneumatic lifting chair 2 for the drive rod 65 to slide. A sliding hole 1a is provided on the top of the housing 1 along the front of the pneumatic lifting chair 2 for the connecting plate 63 to slide through. During exercise, the patient sits on the pneumatic lifting chair 2, and the pneumatic lifting chair 2 is adjusted to the appropriate position according to the patient's body shape. At an appropriate height, the patient places both feet on the two sets of foot restraint frames 64 respectively. The drive motor 4 drives the reciprocating screw 3 to rotate, and the reciprocating screw 3 drives the screw nut 5 to move back and forth. When the screw nut 5 moves back and forth, it drives the two sets of "L"-shaped plates 62 to move back and forth. When the "L"-shaped plates 62 move, they drive the drive rod 65 to slide along the wave groove 61a, thereby causing the drive rod 65 to move up and down. The drive rod 65 drives the "L"-shaped plates 62 to move up and down. The "L"-shaped plates 62 drive the foot restraint frames 64 to move synchronously through the connecting plate 63. Therefore, the foot restraint frames 64 move up and down while moving back and forth along the front of the pneumatic lifting chair 2, causing the patient's legs to bend repeatedly forward and backward while bending up and down. This allows the patient's ankle, knee, and hip joints to bend repeatedly, achieving comprehensive exercise of the lower limbs.

[0029] like Figure 1 and Figure 4 As shown, the foot restraint frame 64 is shaped like a slipper, which makes it convenient for patients to use. When using it, the foot is simply inserted into the foot restraint frame 64. An anti-slip pad is fixed inside the foot restraint frame 64 to prevent slipping.

[0030] like Figures 2-4 As shown, a sliding groove is provided on the side wall of the lead screw nut 5 in the vertical direction. A slider 66, which is slidably disposed inside the sliding groove, is fixedly connected to the side of the "L"-shaped plate 62 near the lead screw nut 5. The "L"-shaped plate 62 is slidably connected to the lead screw nut 5 through the "L"-shaped plate 62.

[0031] like Figure 2 and Figure 3 As shown, a fixing plate 7 is fixedly connected inside the housing 1. Bearing seats 8 are fixedly connected to both the inner wall of the housing 1 and the fixing plate 7. The two sets of bearing seats 8 are arranged opposite each other. The reciprocating screw 3 rotates through the fixing plate 7 and the two sets of bearing seats 8. The drive motor 4 is fixedly connected to the fixing plate 7. The rotating shaft of the drive motor 4 is fixedly connected to the reciprocating screw 3. The reciprocating screw 3 is rotatably arranged inside the housing 1 through the fixing plate 7 and the two sets of bearing seats 8. The drive motor 4 is fixed inside the housing 1 through the fixing plate 7.

[0032] like Figure 1 and Figure 2 As shown, multiple sets of support legs 9 are fixedly connected to the outside of the housing 1 to increase the support area of ​​the device. The multiple sets of support legs 9 are equidistantly arranged, and these multiple sets of support legs 9 are used to improve the stability of the device.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
