Detailed Description

In order to make the present application more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

Examples

The utility model provides a three-dimensional medical leg pillow that is used for full knee joint replacement postoperative to suffer from limb to raise for full knee joint replacement postoperative is recovered, can alleviate the swelling of suffering from the limb, and the help knee joint carries out better straightening training, and can effectively reduce the uncomfortable sense of patient, improves its comfort level and tolerance.

The main structure of the medical leg pillow is a cuboid, as shown in fig. 1, the lengths of three sides are different and are respectively 180mm,220mm and 260mm, three connected side surfaces of a vertex A are respectively provided with a first supporting surface 1, a second supporting surface 2 and a third supporting surface 3, the supporting height of the cuboid when the first supporting surface 1 is placed upwards is 260mm, the supporting height of the cuboid when the second supporting surface 2 is placed upwards is 220mm, and the supporting height of the cuboid when the third supporting surface 3 is placed upwards is 180mm; the first supporting surface 1, the second supporting surface 2 and the third supporting surface 3 are respectively provided with a saddle-shaped U-shaped groove for placing the lower leg of the affected limb, the three supporting surfaces can provide different supporting heights so as to be suitable for patients with different heights and leg lengths, the cuboid material selects hard sponge with stronger pressure bearing, and soft sponge with the thickness of 20mm is arranged in the saddle-shaped U-shaped groove, so that the requirements of the patients on not only lifting the affected limb but also increasing the comfort level and tolerance of the affected limb are met, and the treatment requirement of pressure sores is not caused; the concave arc of the saddle-shaped U-shaped groove is fit with the shape of the human shank, so that the use is comfortable; the outer layer of the medical leg pillow uses waterproof leather, and is provided with the detachable elastic all-cotton coat, so that the skin discomfort can be avoided when the elastic all-cotton coat is contacted with the skin of a patient, the detachable coat is convenient to clean, and the medical leg pillow is beneficial to disinfection and protection when different patients use the medical leg pillow.

In the medical leg pillow provided by the embodiment, the three supporting surfaces provide different supporting heights so as to meet the treatment requirements of different patients; the affected limb is raised by different heights according to the size of the body of the patient and the swelling degree. Simultaneously, the size design of cuboid is not only small and exquisite nimble, possesses sufficient stability again, is difficult for empting when the patient puts the leg. The height of the affected limb is adjusted by utilizing the lengths of the cuboid with different lengths, widths and heights, and meanwhile, the stability is also considered; when the knee joint is straightened, the middle lower section or the ankle part of the lower leg is arranged in the U-shaped groove in the shape of the saddle, and the popliteal fossa and the foot root of the knee joint are suspended, so that the knee joint is straightened, and the possibility of pressure sores at the heel part can be avoided. When the knee joint is suspended, the knee is continuously pressurized by the aid of heavy objects such as sand bags and the like, so that the knee extension training of patients with insufficient knee extension can be helped to be better carried out. The contact surface of the leg pillow and the crus is designed into a saddle-shaped U-shaped groove and covered with sponge, so that the leg pillow can be attached to the leg of the crus, and the use comfort of a patient is improved. If the knee joint of the patient needs to be relaxed, the leg pillow can be placed at the middle upper section of the shank, so that the knee joint is slightly bent, the rear structure of the knee joint can be relaxed and rest, but the raised position can be kept at the same time, and swelling can be relieved.

The medical leg pillow that this embodiment provided helps suffering from the limb and fully raises, and has three kinds of highly optional, maintains that the knee joint straightens, and the knee effect of stretching when pressing the knee with the sand bag is also more reasonable and obvious to can be in keeping the position of stretching and bending the knee rest position between nimble adjustment, the patient uses comfortablely, and can avoid heel portion to press the sore.

In the early period after total knee replacement, especially in the hospitalization period, when a patient lies on the bed in the interval period of walking training under the ground, the middle-lower segment or the ankle part of the lower leg can be placed in the saddle-shaped U-shaped groove of the leg pillow, and the heel and the popliteal fossa part of the knee joint are both suspended in the air, so that the affected limb can be lifted, and the knee joint can be kept straight. For some patients who cannot be fully straightened, weights such as sandbags may also be pressed over the knee to help better straighten the knee when the popliteal fossa is suspended. The height of the affected limb can be flexibly adjusted by using different lengths, widths and heights of the leg pillow. After the knee joint is straightened for a long time or after the leg is pressed, the patient needs to rest, the leg pillow can be moved to the near end of the lower leg to be placed, the middle upper section of the lower leg is placed on the leg pillow, and the knee joint is slightly bent to rest, so that the patient can still stay at the lifting position while the patient has rest on the knee. The interval replacement rest time can be one cycle around 30-60 minutes. The leg pillow is generally recommended to be used in the daytime within the first 3-4 weeks after the operation of the patient, and is generally required to be used during the hospitalization period because the hospitalization time of most patients is not too long at present, and night use is not recommended for night sleeping and relaxing.
