Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a multifunctional rehabilitation device. Background Technology

[0002] After a kidney transplant, patients need to rest in bed while maintaining a certain level of exercise to promote limb movement, accelerate functional recovery, and avoid postoperative complications. However, patients are usually quite weak after the surgery and need tools to assist them during exercise.

[0003] For example, Chinese patent CN219332385U discloses a postoperative rehabilitation exercise support. This device uses an electric telescopic rod to drive the support cylinder to move in an arc under the action of the limiting module, thereby driving the patient's lower limbs to move and exercise.

[0004] However, to improve the effectiveness of exercise, it is generally recommended that patients perform active exercises after surgery, enabling them to actively control their muscles to exercise both the upper and lower limbs.

[0005] Based on this, the present invention designs a multifunctional rehabilitation device to solve the above problems. Summary of the Invention

[0020] Compared to existing technologies, the advantages of this invention are as follows: Patients can rest lying flat on the support bed frame after surgery, allowing for complete muscle relaxation and avoiding anaerobic exercise that could increase the burden on the kidneys. Then, the drive component is activated, moving the moving and massage components. The massage component massages the patient's lower back, while the moving component causes the massage component to reciprocate, changing the massage position and massaging multiple areas of the patient's lower back, increasing patient comfort. When the patient needs to exercise, they can perform upper limb exercises through the upper limb traction mechanism. The auxiliary drive module can be adjusted according to the patient's condition, quickly regulating the traction force of the auxiliary drive module on the support module, thereby changing the intensity required for the patient's exercise. When the patient performs leg exercises, raising their legs, the auxiliary drive module, in cooperation with the support module, assists in supporting the patient's legs, reducing the effort required to raise the legs. This reduces the difficulty of exercise and assists the patient in performing sufficient exercises. Attached Figure Description

[0044] The support module 41 includes a limiting rotating frame 411, a support plate 412, a connecting rope 413, and a rotating wheel 414. The middle part of the limiting rotating frame 411 is rotatably mounted on the support bed frame 1. One end of the limiting rotating frame 411 is fixedly mounted with the support plate 412. The other end of the limiting rotating frame 411 is fixedly connected to one end of the connecting rope 413. The rotating wheel 414 is rotatably mounted on the lower side of the support bed frame 1. The other end of the connecting rope 413 passes around the rotating wheel 414 and is connected to the auxiliary drive module 42.

[0045] The auxiliary drive module 42 includes a counterweight module and a locking module, which are installed on the underside of the support bed frame 1.

[0046] The counterweight module includes a counterweight box 421, a counterweight block 423, and a sliding rod 424. The other end of the connecting rope 413 is fixedly connected to the counterweight box 421. The counterweight box 421 has multiple counterweight slots 422, and the counterweight block 423 is inserted into the counterweight slots 422.

[0048] The upper limb tension mechanism 5 includes a tension rope 51, a handle 52, a guide wheel 53, and a stop bar 54. The lower side of the support bed frame 1 is fixedly connected to one end of the elastic tension rope 51. The guide wheel 53 is rotatably mounted on the lower side of the support bed frame 1, and the stop bar 54 is fixedly mounted on the lower side of the support bed frame 1. The other end of the tension rope 51 passes between the guide wheel 53 and the stop bar 54 and is then fixedly mounted with the handle 52. The support bed frame 1 has a receiving groove 55 for accommodating the handle 52.

[0049] A pneumatic therapy module is also installed on the support plate 412.

[0050] In this embodiment, when the waist massage mechanism 3, leg exercise mechanism 4, and upper limb tension mechanism 5 are working normally, the motor 314 drives the drive gear 315 to rotate, the drive gear 315 drives the driven gear 316 to rotate, and the drive gear 315 and driven gear 316 drive the two reduction gears 317 to rotate; and the two reduction gears 317 rotate in different directions; the rotation of the drive gear 315, driven gear 316, and reduction gear 317 drives the rotating plate 331 to rotate, and the rotating plate 331 drives the first massage block 332 and the second massage block 333 to rotate, thereby massaging the patient's waist through the first massage block 332 and the second massage block 333; when the drive gear 315, driven gear 316, and reduction gear 317 drive the rotating plate 331 to rotate... During rotation, the two reduction gears 317 drive the first follower gear plate 321 and the second follower gear plate 322 to rotate respectively. When the first follower gear plate 321 contacts the first rack 323, the first follower gear plate 321, in cooperation with the first rack 323, drives the reduction gear 317 and the mounting bracket 313 to move. The mounting bracket 313 moves horizontally under the limiting action of the guide rail 312 until the first follower gear plate 321 and the first rack 323 no longer contact each other. Then the second follower gear plate 322 contacts the second rack 324 and cooperates to drive the reduction gear 317 and the mounting bracket 313 to reset. This drives the mounting bracket 313 to move horizontally back and forth, so that the multiple sets of first massage blocks 332 and second massage blocks 333 on the mounting bracket 313 move horizontally within the waist area; increasing Massage range; when the patient needs to perform upper limb exercises, the handle 52 can be pulled, which pulls the tension rope 51 to stretch the rope for exercise; when the patient is resting, the locking cylinder 425 drives the support block 426 to move vertically, supporting the counterweight box 421 through the support block 426, so that the counterweight box 421 no longer pulls the limit rotating frame 411 through the connecting rope 413; when the patient is performing leg exercises, different numbers of counterweight blocks 423 can be inserted into the counterweight slots 422 in the counterweight box 421 as needed; the locking cylinder 425 resets, driving the support block 426 to reset, so that the support block 426 no longer supports the counterweight box 421; the counterweight box 421 and the counterweight blocks 423 tend to move downward under the action of gravity on the slide rod 424, thus moving downward through the connecting rope 422. 13 drives the limiting rotating frame 411 to maintain its rotational trend. At this time, the patient raises his leg, and the rotation of the limiting rotating frame 411 drives the support plate 412 to rotate. The limiting rotating frame 411 and the support plate 412 support the patient's leg. The counterweight box 421 and the counterweight block 423 drive the limiting rotating frame 411 to rotate through the connecting rope 413, thereby providing auxiliary force for the patient to raise his leg through the limiting rotating frame 411 and the support plate 412. After the patient's leg is raised, it can relax naturally. Under the action of the patient's leg weight, the limiting rotating frame 411 is pressed down. The limiting rotating frame 411 drives the counterweight box 421 and the counterweight block 423 to reset through the connecting rope 413. This provides auxiliary support for the patient's leg exercise, reduces the difficulty of the exercise, and reduces the force required for the patient's exercise.The pneumatic therapy module allows for convenient pneumatic therapy when patients are agitated. It also helps restrain patients, preventing them from tearing their incisions due to restlessness immediately after surgery.

[0051] Example 3: In some embodiments, such as Figure 9 As shown, the pneumatic therapy module includes a conformal mask 61, a zipper 62, a heating pad 63, and independent airbags 64. A conformal mask 61 that conforms to the shape of the leg is fixedly installed on the support plate 412. A zipper 62 is fixedly installed on the upper side of the conformal mask 61. A heating pad 63 is fixedly installed on the outer side of the conformal mask 61. Multiple sets of independent airbags 64 are fixedly installed inside the conformal mask 61. Each set of independent airbags 64 is connected to an air pump through a hose.

[0052] In this embodiment, the patient's leg is placed inside the conformal cover 61, and the conformal cover 61 is closed by the zipper 62. Then, the independent airbags 64 are wrapped around the patient's leg by the air pump. The air pump changes the pressure in the different independent airbags 64, thereby performing air pressure massage on the patient's leg to relieve the patient's discomfort. The heating plate 63 can be heated so that the heat from the heating plate 63 is transferred to the independent airbags 64 and dispersed, so that the independent airbags 64 can perform air pressure massage on the patient's leg while simultaneously providing heat therapy.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
