Description

Technical Field

[0001] This utility model relates to the field of knee joint rehabilitation training technology, and in particular to a knee joint rehabilitation treatment device. Background Technology

[0002] Knee rehabilitation therapy is a series of comprehensive treatment measures for knee injuries, diseases, or functional impairments, aiming to promote knee joint recovery, reduce pain, improve joint function, and improve patients' quality of life. Knee rehabilitation chairs are a common knee rehabilitation therapy device.

[0003] Current knee rehabilitation chairs typically consist of a chair and a leg rest mounted in front of the chair that swings back and forth. While this type of device can flex and extend the patient's knee, its function is relatively limited, only meeting basic leg flexion needs and thus having a limited effect on knee rehabilitation. Therefore, a new knee rehabilitation device is proposed. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems of the above-mentioned knee joint rehabilitation device, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a knee joint rehabilitation treatment device, including a hollow base and a seat fixedly connected to the top of the base;

[0007] On the front side of the chair seat, below the seat surface, there is a roller that can move back and forth in a direction parallel to the seat surface to massage and repeatedly bend the legs.

[0008] Two sets of sliding rods are slidably passed through the base in a direction parallel to the front and back of the chair seat surface, and the roller is rotatably connected between the two sets of sliding rods;

[0009] Inside the base, a crank driven by a motor is rotatably mounted. A drive rod is fixedly connected between the two sets of slide rods. A connecting rod is hinged between the crank and the drive rod. When the crank rotates, it drives the two sets of slide rods to move back and forth.

[0010] In a preferred embodiment of the knee joint rehabilitation treatment device of this utility model, the roller has two sets of extrusion grooves on its surface around its axis, and the two sets of extrusion grooves are symmetrically arranged on both sides of the roller.

[0011] In a preferred embodiment of the knee joint rehabilitation device of this utility model, the width of the compression groove gradually decreases, a rack is fixedly connected to the outer side of the base, the roller and the slide rod are connected by a rotating shaft through the slide rod, a gear that meshes with the rack is fixedly connected to one end of the roller shaft near the rack, and the roller rotates in the direction of narrowing of the compression groove under the drive of the gear when it moves forward of the seat, so that the gradually narrowing groove wall of the compression groove squeezes the leg muscles.

[0012] As a preferred embodiment of the knee joint rehabilitation treatment device of this utility model, the outer side of the base is also fixedly connected with a shielding cover that can shield the rack, gear and corresponding slide rod.

[0013] In a preferred embodiment of the knee joint rehabilitation treatment device of this utility model, several sets of protrusions are provided in both sets of compression grooves, and the several sets of protrusions in the compression grooves are evenly distributed.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up rollers that can move back and forth in a direction parallel to the seat surface of the chair, when the patient puts their legs on the rollers, the rollers can cause the patient's legs to bend repeatedly. At the same time, the rollers can massage the patient's legs as they move, thereby promoting blood circulation in the lower limbs. Compared with existing technologies, this technology is more functional.

[0016] 2. The device uses two sets of squeezing grooves to squeeze and massage the patient's leg muscles as the roller moves, which can further enhance the massage effect. Attached Figure Description

[0027] Reference Figures 1-4 As an embodiment of the present invention, a knee joint rehabilitation treatment device is provided, which includes a hollow base 1 and a seat 2 fixedly connected to the top of the base 1. On the front side of the seat 2, below its seat surface, a roller 3 is rotatably provided that can move back and forth in a direction parallel to the front and back of the seat surface to massage and repeatedly bend the leg.

[0028] Two sets of sliding rods 4 are slidably mounted on the base 1 along the front-to-back direction parallel to the seat surface 2. A roller 3 is rotatably connected between the two sets of sliding rods 4. Inside the base 1, a crank 6 driven by a motor is rotatably mounted. Figure 3As shown, there are plate strips for mounting the crank 6 fixed on both sides of the crank 6 inside the base 1. The two sides of the crank 6 are respectively rotated and passed through two sets of plate strips. The crank 6 is rotatably mounted in the base 1 in this way. A drive rod 5 is fixedly connected between the two sets of slide rods 4. A connecting rod 7 is hinged between the crank 6 and the drive rod 5. When the crank 6 rotates, it drives the two sets of slide rods 4 to move back and forth.

[0029] Two sets of extrusion grooves 3a are formed on the surface of the roller 3 around its axis. The two sets of extrusion grooves 3a are symmetrically arranged on both sides of the roller 3. When in use, the patient sits on the seat 2 with his legs on the roller 3. The motor drives the crank 6 to rotate. The crank 6 drives the two sets of slide rods 4 to move back and forth through the connecting rod 7 and the drive rod 5. The two sets of slide rods 4 drive the roller 3 to move back and forth. When the roller 3 moves back and forth, it causes the patient's legs to bend repeatedly, thereby exercising the knee joint. In addition, the roller 3 provides rolling massage to the patient's legs, which can promote blood circulation in the lower limbs.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the width of the compression groove 3a gradually decreases. A rack 8 is fixedly connected to the outside of the base 1. The roller 3 and the slide rod 4 are connected by a rotating shaft through the slide rod 4. A gear 9 that meshes with the rack 8 is fixedly connected to one end of the roller 3's rotating shaft near the rack 8. When the roller 3 moves forward toward the seat 2, it rotates in the direction of the narrowing compression groove 3a under the drive of the gear 9, so that the gradually narrowing groove wall of the compression groove 3a can compress the leg muscles.

[0031] like Figure 1 As shown, a shield 10 is also fixedly connected to the outside of the base 1 to shield the rack 8, gear 9 and the corresponding slide bar 4. The shield 10 is used to improve the safety of the device.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, both sets of extrusion grooves 3a are provided with several sets of protrusions. The several sets of protrusions in the extrusion grooves 3a are evenly distributed. These several sets of protrusions are to further enhance the massage effect.

[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.
