Description

A kind of posture cushion after hip and knee joint replacement

technical field

The utility model relates to the field of medical recovery instruments, in particular to a body position pad after replacement of hip and knee joints.

Background technique

Patients after hip and knee replacement often need to raise the lower limbs above the heart level to promote blood circulation and maintain the functional position of the limbs, and to be in a neutral abduction position. After hip replacement patients also need to maintain a neutral abduction position to prevent leg Adduction and external rotation lead to joint dislocation.

Now clinically, pillows are often used to raise the lower limbs. The height of the lift is affected by the patient's age, physique, and fat or thin. Therefore, it is difficult to use one or two pillows to determine the height. Between one pillow and two pillows, it is difficult to find a suitable height, and it cannot play a braking role when lying on the back or lying on the side, which brings inconvenience to clinical work and the patient's comfort level is not good.

A position pad after hip and knee replacement, comprising a base and a support pad above the base, the top of the support pad is provided with a support surface, and the support surface is provided with a groove for accommodating human legs, and the groove is along the The supporting pads are generally arranged, and the base is provided with a lifting structure for connecting the supporting pads.

As a further improvement of the utility model, a popliteal hole is provided in the middle of the groove corresponding to the position of the popliteal fossa.

As a further improvement of the utility model, the cross section of the groove is an arc surface.

As a further improvement of the utility model, the diameter of the groove decreases along the length direction.

As a further improvement of the utility model, the support pad includes a fixed end hinged to the base, and a movable end opposite to the fixed end, and the lifting structure is connected to the movable end.

As a further improvement of the present utility model, the lifting structure includes a lead screw pair parallel to the support pad, the screw rod of the lead screw pair includes a part in the base and a part outside the base, and the nut of the lead screw pair is located on the base A strut is hinged inside, and the other end of the strut abuts against the bottom surface of the support pad.

As a further improvement of the utility model, the part of the screw rod outside the base is connected with an operating handle.

As a further improvement of the utility model, the side of the groove close to the movable end of the support pad is detachably equipped with a support bottom plate.

As a further improvement of the utility model, the surface of the support pad is covered with a buffer layer.

The beneficial effects of the utility model are: the utility model is provided with a groove on the support pad, which can better brake the affected limb contained in it, avoid external rotation or adduction of the leg, and the medical staff can use it according to the patient's condition. The lift raises or lowers the support pad to a suitable height, making the patient's recovery more comfortable.

detailed description

The position pad after hip and knee joint replacement as shown in Figure 1 and Figure 2 includes a base 1 and a support pad 2 above the base 1, the top of the support pad 2 is provided with a support surface, and the support surface is provided with a concave for accommodating human legs. Grooves 21 and grooves 21 are provided along the entire length of the support pad 2 . The base 1 is provided with a lifting structure connecting the support pad 2, the patient's legs can be put into the groove 21, the function of the groove 21 is used to prevent the leg from turning outward or adduction, and the support pad 2 is lifted up and down through the lifting structure, To raise the affected limb and obtain a suitable height for the affected limb.

As a further preferred embodiment, a popliteal hole 22 is provided in the middle of the groove 21 corresponding to the position of the popliteal fossa. The popliteal hole 22 is a round hole with a size of 15cm*10cm, which can avoid long-term elevation of the affected limb and pressure on the popliteal vein, which will cause blood supply disturbance in the lower limbs. For details, refer to FIG. 3 .

As a further preferred embodiment, the cross section of the groove 21 is an arc surface, and the arc surface can fit the affected limb well, and can better brake the external rotation or adduction of the affected limb.

As a further preferred embodiment, the diameter of the groove 21 decreases along the length direction, as shown in FIG. 2 , the diameter decreases successively from the right end to the left end, which is more suitable for the physiological structure of human legs.

As a further preferred embodiment, as shown in Figure 3 and Figure 4, the support pad 2 includes a fixed end hinged to the base 1, and a movable end opposite to the fixed end, the lifting structure is connected to the movable end, and the lifting structure can drive the support pad 2 The support pad 2 is raised or lowered by rotating along the hinge at the fixed end.

As a preferred embodiment of the lifting structure, the lifting structure includes a screw pair parallel to the support pad 2 , and the screw pair is composed of a screw rod 3 and a nut 4 . The screw 3 includes a part in the base 1 and a part outside the base 1. The nut 4 of the screw pair is located in the base 1 and is hinged with a strut 5. The other end of the strut 5 abuts against the bottom end surface of the support pad 2. After the medical personnel rotate the screw mandrel 3, the nut 4 drives the strut 5 to move back and forth relative to the screw mandrel 3, thereby driving the lifting pad to go up and down. The structure of the lead screw pair makes the lifting height of the support pad 2 more accurate.

Certainly also can not only use the form of lead screw pair as lifting structure, as long as can drive support pad 2 lifting and controllable lifting height all should be within the scope of protection of the present utility model.

As a preferred embodiment of the lifting structure, the part of the screw rod 3 outside the base 1 is connected with an operating handle 6, which makes the operation more convenient. The height and abduction angle of the support pad 2 are regulated by manually adjusting the screw rod 3 , so that different patients can adjust different heights and different abduction angles, as shown in FIGS. 3 and 4 .

As a further preferred embodiment, the side of the groove 21 near the movable end of the support pad 2 is detachably equipped with a support base plate 7, the support base plate 7 can prevent the foot from drooping and can assist the patient to perform the exercise of the ankle pump function. For details, refer to the figure 4.

As a further preferred embodiment, the surface of the support pad 2 is covered with a cushioning layer (not shown), so as to give the patient a more comfortable feeling.

The body position cushion of the above-mentioned embodiment can not only be used for the supine position of the hip joint, knee joint patient, also can be used for the side lying position.

The above descriptions are only preferred implementations of the present utility model, and they do not constitute a limitation to the protection scope of the present utility model.
