[0002] Postoperative rehabilitation exercise is very important for knee replacement surgery, which directly affects the patient's quality of life after surgery. On the first day after surgery, due to anesthesia, the patient needs to rest in bed and raise the affected limb to reduce swelling and relieve pain. Long-term ankle dorsiflexion training, flexion training and straight leg raising training can be adhered to to enhance the strength of the quadriceps to prevent venous thrombosis. Generally, patients are required to flex to 90 degrees within 3 weeks after surgery. Therefore, how to make a ward that can assist patients in postoperative training and maintain a good posture after surgery.

[0003] The existing patent (application number: CN201921254569.5) proposes a multifunctional soft pillow for patients after knee replacement surgery, including a soft pillow body, the soft pillow body is a right-angled triangular prism structure, the inclined surface of the soft pillow body is provided with a U-shaped groove along its length direction, the vertical section of the U-shaped groove is a triangular structure, an inflatable air cushion A is provided on the wide side of the U-shaped groove, the inflatable air cushion A is tightly attached to the sole of the human body, the inflatable air cushion A is connected to an inflatable duct A, and the end of the inflatable duct A is connected to an inflatable air bag A, and the narrow side of the U-shaped groove is provided with an inflatable air cushion B, the inflatable air cushion B is tightly attached to the surface of the human knee joint, the inflatable air cushion B is connected to an inflatable duct B, and the end of the inflatable duct B is connected to an inflatable air bag B, which effectively performs rehabilitation training for the ankle and knee joints.

[0004] The current soft pillow has a limited lifting angle and cannot provide the required angle of support for the patient's leg recovery according to the patient's needs.

The knee joint angle during the operation can be flexed by 5 degrees to 90 degrees, which can be suitable for the patient's required knee joint angle after surgery.

[0034] Furthermore, as a specific implementation of the present invention, the present invention provides a multifunctional pillow pad for use after joint replacement surgery.

[0035] Specifically, Figure 3The invention also includes an adjustment component, which includes a mounting groove 11 opened on the top surface of the support plate 1, a gear 12 is rotatably installed inside the mounting groove 11, and a first rack 13 and a second rack 14 are slidably installed inside the mounting groove 11, the first rack 13 and the second rack 14 are both meshed and connected with the gear 12, one end of the first rack 13 is fixedly connected to the middle part of the bottom surface of the connecting plate 8, the other end of the second rack 14 is fixedly connected to a telescopic push rod 15, and the end of the telescopic push rod 15 away from the second rack 14 is fixedly connected to a handle 16.

[0036] In the utility model, after the pin rod 9 is pulled out from the pin hole 10, the patient holds the handle 16 and pushes the telescopic push rod 15 to drive the second rack 14 to slide back and forth. During the sliding process, the second rack 14 drives the gear 12 to rotate, and the gear 12 drives the first rack 13 to slide back and forth. The first rack 13 drives the connecting plate 8 to slide back and forth on the support plate 1. The connecting plate 8 can drive the connecting rod 5 to move, so that the leg support plate 3 undergoes reciprocating angle changes, causing the patient's knee joint to bend, thereby assisting the patient in performing knee flexion rehabilitation training, so that the pillow has the effect of rehabilitation training.

[0037] Furthermore, as another specific implementation of the present invention, the present invention provides a multifunctional pillow pad for use after joint replacement surgery.

[0038] Specifically, Figure 3 It is shown that a hinge seat 2 is symmetrically fixedly installed on the top surface of the support plate 1, and a leg support plate 3 is rotatably installed between the two hinge seats 2.

[0039] In the utility model, the leg support plate 3 is installed conveniently.

[0040] Furthermore, as a specific implementation of the present invention, the present invention provides a multifunctional pillow pad for use after joint replacement surgery.

[0049] Working principle: By adjusting the position of the connecting plate 8 on the supporting plate 1, the position of the connecting rod 5 can be adjusted, and then the angle of the leg support plate 3 and the cushion body 4 can be adjusted. According to the needs, the required knee flexion angle and height can be temporarily adjusted according to the patient's postoperative condition. The angle can be kept unchanged after adjustment. The pillow pad angle adjustment is flexible and changeable, and the adjustable angle range is large, which can make the knee joint flexed 5 degrees to 90 degrees during the operation, which can be suitable for the patient's required knee joint angle after surgery. When the pin rod 9 is pulled out from the pin hole 10, the patient holds the handle 16 and pushes the telescopic push rod 15 to drive the second rack 14 to slide back and forth. The second rack 14 drives the gear 12 to rotate during the sliding process, and the gear 12 drives the first rack 13 to slide back and forth. The first rack 13 drives the connecting plate 8 to slide back and forth on the supporting plate 1. The connecting plate 8 can drive the connecting rod 5 to move, so that the leg support plate 3 undergoes reciprocating angle changes, so that the patient's knee joint is bent, thereby assisting the patient to perform knee flexion rehabilitation training, so that the pillow has the effect of rehabilitation training.

[0050] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
