Detailed Description

As shown in fig. 1 to 3, the nursing pad after hip joint operation is provided with a groove with a certain included angle on the upper surface 1 of the pad body, when a patient is in lateral position, the knee joint of the affected limb can be slightly bent and placed in the groove of the nursing pad, so that the affected limb is supported and is not easy to slide off the pad body. The bottom 2 of the cushion body is provided with a narrow part which can lead the cushion body to freely turn left and right.

In the design shown in fig. 1, the groove is in the shape of an arrow with ">" or "<", and a left groove 71 of the ">" shape and a right groove 72 of the "<" shape intersect with each other at the head of the arrow to form a common region 70. The arrangement of the shared area enables the knee joint of the patient to be supported under different knee bending degrees. In the design shown in fig. 4, the left groove 71 of ">" and the right groove 72 of "<" do not touch each other at the head of the arrow. In the design shown in fig. 10, the ">" shaped left groove 71 and the "<" shaped right groove 72 cross each other in the middle of the arrow. When the patient turns over 30 degrees to the left from the lying position, the affected limb of the patient is placed in the groove to be supported. Because the left groove and the right groove are crossed in the middle, the height of the nursing pad after the hip joint operation can be reduced on the premise of not weakening the supporting effect of the grooves on the affected limb, and the height of the quilt covering the nursing pad is reduced, so that the warm-keeping effect of the quilt is better.

In the design shown in fig. 5 to 6, the pad body further comprises a first leg support bracket 73 and a second leg support bracket 74 which are connected by a hinge 75, pulleys 76 are respectively arranged at the lower parts of the first leg support bracket 73 and the second leg support bracket 74, a track plate 77 in a shape of ">" or "<" which can be matched with the pulleys is arranged in the groove of the pad body, and the track plate is made of hard material. The leg support frame is mounted in the track plate 77 by means of pulleys. When the patient lies on his side and wants to straighten the affected limb resting in the recess, as shown in fig. 5, the angle between the first leg support bracket 73 and the second leg support bracket 74 is kept at 180 degrees. When the patient lies on the side and wants to bend the patient placed in the groove, the first leg support frame and the second leg support frame approach each other along with the bending of the knee of the affected limb to form a certain included angle. The patient's knee bending level as shown in fig. 6 reaches the maximum knee bending level set by the nursing pad. The design of track board and pulley makes the patient can be according to oneself needs, selects comfortable degree of bending the knee wantonly, and the contained angle between for example first shank support frame and the second shank support frame lies in the nursing pad and sets for the biggest degree of bending the knee and the affected limb unbends between, and no matter in which position knee joint can both obtain the support of recess.

In an improved design scheme, the pad body is further provided with a bandage for placing limbs to slide down. In the more specific embodiment shown in fig. 1, the first and second straps 81 and 82 are provided at both ends of the groove, the tightness of the straps is preferably such that the affected limb can move freely therein, and the distance between the first and second straps is such that the affected limb will not bend more than 90 degrees when the affected limb bends the knee. In another more preferred embodiment, a third strap 83 is included to avoid excessive hip abduction, for example, at about the middle of the bolster body. The strap may be of hook and loop design or of snap design. As shown in the nursing pad of FIG. 10, first and second straps 81 and 82 are provided at both ends of the nursing pad and span over left and right side grooves 71 and 72, respectively. The third strap 83 is spanned at the tip of the arrow shape of the groove.

As shown in FIG. 1, the bottom 2 of the pad body is in a sharp angle shape, and may be in a circular arc shape as shown in FIG. 7. Other narrow part design schemes which can lead the cushion body to freely turn left and right belong to the scope of the utility model. In order to prevent the bottom of the nursing pad from deforming in the overturning process, a hard anti-pressing block can be added on the bottom. As shown in fig. 7, a steel pipe 21 is placed at the bottom. In another optimized proposal, a heater and a heating power supply are arranged in the steel tube in fig. 7, which makes the nursing pad have the function of hot compress. The heating power supply can adopt a dry battery and can be repeatedly charged. A medicine bag 10 can be arranged on the nursing pad, and some medicinal materials with treatment effect can be placed in the medicine bag. The heat emitted by the heater can make the medicine exert more and better medicine properties, so as to achieve the effect of medicine application.

The nursing pad is made of soft sponge materials, and wrapping cloth can be added on the nursing pad, so that the nursing pad is convenient to clean and disinfect. The bandage can be made of a widened and thickened cotton cloth strip.

When a patient just finishes an operation, the patient needs to lie down and avoid that the abduction amplitude of the hip joint cannot be too large, and generally needs 30 degrees of abduction of the hip joint. At this time, the nursing pad is placed between the legs of the patient to abduct the affected limb. The bottom of the cushion body is attached to the sickbed surface, the left leg of the patient is placed below the left side part 5 of the cushion body, and the right leg is placed below the right side part 6 of the cushion body. In a modified proposal, the nursing pad body is gradually enlarged in an isosceles trapezoid from the near end 3 (the end close to the patient) to the far end 4 (the end far away from the patient), and is more suitable for the lying position of the patient with the open legs.

In the clinical example shown in fig. 8 and 9, in which the patient may turn after hip surgery, the right leg 101 of the patient is the affected limb leg. First, as shown in fig. 8, the right side portion 6 of the nursing pad is placed against the bed surface of the hospital bed with the upper surface of the groove facing the right leg, and the bands 81 and 82 fix the right leg of the patient on the nursing pad while the right leg 101 and the left leg 102 of the patient are spaced apart by the nursing pad so that the legs are kept open. As shown in fig. 9, when the patient turns over 30 degrees from the lying position to the left, the affected limb of the patient is placed in the groove, and the binding band is added to fix the affected limb so as to avoid the hip joint from bending more than 90 degrees. Therefore, the affected limb can be supported by the groove, and the fatigue of the leg is reduced. And the affected limb can be placed in the groove of the nursing pad in the most relaxed state with the knee joint 103 slightly flexed when the patient is in lateral position. The bandage can further prevent the limbs from sliding off. This lets when the unconscious patient uses the nursing pad, can effectual restriction its position, prevents to fix inefficacy. Also let the patient of consciousness clarity use the nursing pad, the patient need not worry constantly that the leg of oneself can slide off the nursing pad and sleep and not step on really, has guaranteed the quality of sleep and rest.

The nursing pad of the utility model is used as an auxiliary instrument for the patient to turn over after operation, which can avoid the occurrence of the common complication 'dislocation of hip joint' after hip joint replacement; when the nursing pad is used in the lateral decubitus position, the hip joint can be prevented from adducting, and the knee joint is slightly bent to enable the limb to be in a relaxed state. Has good clinical application value in the rehabilitation nursing after hip joint replacement.
