Japanese Patent No. 3878770

Although the abduction pillow described in Patent Document 1 has a certain effect on maintaining the abduction state of the affected limb, it is difficult for the patient to change the position such as from the supine position to the lateral decubitus position by himself / herself. Therefore, at the time of admission, it is necessary to call a nurse or the like to ask for assistance every time the body position is changed, and there is a problem that the burden on daily life is large even after discharge.

Based on the above circumstances, it is an object of the present invention to provide an abduction pillow capable of easily changing the body position by the wearer while maintaining a desired abduction state of the leg.

The present invention includes a main body having a first thigh accommodating portion and a second thigh accommodating portion that define a substantially columnar space continuously provided in the vertical direction, and the first thigh accommodating portion and the second thigh accommodating portion. The inner surface of the thigh becomes larger as the distance from each other approaches the lower end of the main body, and when the wearer accommodates the thigh in the first thigh accommodating portion and the second thigh accommodating portion, at least one of the thighs is attached. It is formed in a shape that maintains the abduction state with respect to the pelvis of the person, and the vertical length of the main body is a length that does not touch the knee when worn, and at least a part of the back surface of the main body is , An abduction pillow with a curved surface that is convex outward.

The abduction pillow of the present invention can be attached to and detached from the main body so as to cover at least a part of the first thigh accommodating portion and the second thigh accommodating portion that communicate with the outside of the main body. The provided deviation prevention member may be further provided.

The left and right side surfaces of the main body may be configured to be substantially flat or deformable to be substantially flat.

According to the abduction pillow of the present invention, the wearer can easily change the posture while maintaining the desired abduction state of the leg.

It is a front view of the abduction pillow which concerns on 1st Embodiment of this invention. It is a bottom view of the abduction pillow. It is a left side view of the abduction pillow. It is a figure which shows typically the state which the abduction pillow is attached. It is a front view of the main body in the modified example of the abduction pillow. It is a bottom view of the abduction pillow which concerns on the 2nd Embodiment of this invention. It is a figure which shows typically the abduction pillow in the state which the wearer took a lateral decubitus position.

The first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a front view of the abduction pillow 1 of the present embodiment. FIG. 2 is a bottom view of the abduction pillow 1. FIG. 3 is a left side view of the abduction pillow 1. As shown in FIGS. 1 to 3, the abduction pillow 1 includes a main body 10 and a lid portion (deviation prevention member) 30 attached to the main body 10.

The main body 10 has a hardness such that the outer shape is not significantly deformed by the pressure applied at the time of mounting, and examples of the material include resin, paper, wood, and metal. Above all, it is preferable to use resin, paper, or the like because the weight of the main body 10 can be reduced. As the resin, a hard sponge formed in a porous form can also be used. In order to improve the wearing feeling of the user, the entire or part of the surface of the main body may be covered with a flexible material such as cloth, or the edge portion may be chamfered or rounded.

As shown in FIG. 1, the main body 10 has a first thigh accommodating portion 21 and a second thigh accommodating portion 22 that define a substantially columnar space (columnar space) so that the columnar space extends in the vertical direction of the main body 10. , Are provided side by side in the left-right direction. The inner surface shapes of the first thigh accommodating portion 21 and the second thigh accommodating portion 22 are set so that the distance d between the inner surfaces gradually increases as the lower end 10a of the main body 10 approaches.

As shown in FIG. 1, in the columnar space defined by the first thigh accommodating portion 21, the axis X1 of the first thigh accommodating portion 21, which is a line connecting the centers of gravity in a cross-sectional shape orthogonal to the vertical direction of the main body 10, is The angle is formed so as to be non-parallel to the vertical direction of the main body 10. Similarly, the axis X2 of the second thigh accommodating portion 22 is also angled so as to be non-parallel to the vertical direction of the main body 10.

A part of the outer peripheral surfaces on the left and right sides of the main body 10 is removed in the vertical direction. As a result, the main body 10 is configured to be accessible from the side in the columnar space defined in the first thigh accommodating portion 21 and the second thigh accommodating portion 22. The wearer can insert his / her thigh from the side of the main body 10 and accommodate the thigh in the columnar space of the first femur accommodating portion 21 and the second thigh accommodating portion 22.

As shown in FIG. 2, the back surface 11 of the main body 10 is formed in a curved surface shape that is convex outward. In the present embodiment, the curved surface shape of the back surface 11 shown in FIG. 2 is continuous in the vertical direction of the main body 10.

One lid portion 30 is provided corresponding to each of the first thigh accommodating portion 21 and the second thigh accommodating portion 22. One end of each of the pair of lids 30 is fixed to the outer peripheral surface of the main body 10, and the other end 30b is detachably attached to the outer peripheral surface of the main body 10. As a removable configuration, various known mechanisms such as a hook-and-loop fastener, a magnet, a hook, and a button can be appropriately selected and used.
The material of the lid portion 30 may be the same as or different from that of the main body 10.

The operation when the abduction pillow 1 of the present embodiment configured as described above is used will be described.
The wearer allows the thighs of both legs to enter from the side of the main body 10 with the other end 30b of each lid 30 separated from the main body 10, and the columnar space of the first thigh accommodating portion 21 and the second thigh accommodating portion 22. The thigh is housed inside. After that, when the other end 30b of each lid portion 30 is attached to the outer peripheral surface of the main body 10, the attachment of the abduction pillow 1 is completed.

FIG. 4 shows the abduction pillow 1 after the mounting is completed. The thigh Ths that have entered from the left and right sides of the main body 10 are housed in the first thigh housing section 21 and the second thigh housing section 22.
While the abduction pillow 1 is being worn, the femur Th accommodated in the first thigh accommodating portion 21 and the second thigh accommodating portion 22 is preferably held in the abduction state with respect to the wearer's pelvis. Further, by attaching the other end 30b of each lid portion 30 to the outer peripheral surface of the main body 10, the portion communicating with the outside of the main body is covered with the lid portion 30 so that the columnar space can be accessed on the left and right sides of the main body 10, and the femur Th. Is suppressed from deviating from the first thigh accommodating portion 21 and the second thigh accommodating portion 22.

While wearing the abduction pillow 1, for example, when changing the position from the supine position to the lateral decubitus position, the wearer exercises to rotate the area below the lumbar region or the whole body around the body axis. Since the back surface 11 of the main body 10 is formed in a curved shape, the main body 10 can be easily rotated around the body axis by the above-mentioned movement. As a result, the wearer does not need the assistance of another person such as a nurse, and can easily change the position by himself / herself.
During the postural change, both thighs of the wearer are housed in the first femur accommodating portion 21 and the second femur accommodating portion 22 provided in the single main body 10, and therefore, during and after the postural change. The relative positions of both thighs do not change significantly, and unintended adduction and internal rotation are unlikely to occur. Therefore, the abduction state of the affected thigh can be suitably maintained during and after the change of position.

As described above, according to the abduction pillow 1 of the present embodiment, the wearer can easily change his / her body position while maintaining the abduction state of the wearer's legs.

Further, since the other end 30b is provided with the lid portion 30 that can be attached to and detached from the main body 10, it is possible to suitably balance the thigh accommodating operation at the time of wearing and the prevention of the deviation of the thigh at the time of wearing and changing the posture.

In the present embodiment, an example has been described in which the axes of both the first thigh accommodating portion 21 and the second thigh accommodating portion 22 form an angle with respect to the vertical direction of the main body 10. Such a shape is particularly suitable for patients who have undergone bilateral hip replacement, but this is not essential to the present invention.

In the modified example shown in FIG. 5, only the axis X2 of the second femur accommodating portion 22 is angled with respect to the vertical direction of the main body 10, and the axis X1 of the first femur accommodating portion 21A is parallel to the vertical direction of the main body 10. Is. Thus, only one of the two femur containments may be configured to hold the contained femur in an abducted state with respect to the wearer's pelvis. For patients who have undergone hip replacement on only one side, the above-mentioned effect can be sufficiently obtained even with an abduction pillow having a main body in which only the thigh accommodating portion on the corresponding side is configured as described above.
Further, if only one of the thigh accommodating parts is configured so that the accommodating femur can be held in the abduction state and the front surface is formed in a curved shape in addition to the back surface of the main body, the femur can be attached by flipping back and forth as necessary. Therefore, one abduction pillow can be configured to accommodate patients who have undergone replacement surgery on either side.

The vertical dimensions of the main body can be set as appropriate, but it is preferable that the dimensions are set so that they do not touch the knees when worn. In this way, the region below the knee can be moved to some extent even when worn, and the wearer's feeling of restraint can be reduced while maintaining the abduction state.

Further, the lid portion 30 does not need to be provided over the vertical direction of the main body, and may be provided only in a partial range in the vertical direction. Further, the other end of the lid portion may be configured to be removable from the inner surface of the femur accommodating portion, or both ends may be detachable from the main body so as to be removable from the main body.
When both ends of the lid portion 30 are attached to the outer peripheral surface of the main body, the thighs are less likely to be pressed when the lid portion is closed, and it is possible to suppress the occurrence of skin troubles due to contact between the lid portion and the skin. it can.

Further, the curved surface shape provided on the back surface of the main body does not necessarily have to be provided in the vertical direction of the main body, and at least a part of the portion that comes into contact with the bed, the futon, etc. when the wearer takes the supine position is a curved surface. It may be in shape. The specific mode of the curved surface shape is not limited to the gutter shape described above, but can be freely set to a spherical shape or the like, but in order to facilitate the rotational movement around the body axis of the main body described above, the dorsal side of the curved surface shape is the most. It is preferable that the protruding portion is not flat when viewed in the vertical direction of the main body.

A second embodiment of the present invention will be described with reference to FIGS. 6 to 7. In the following description, the same reference numerals will be given to the configurations common to those already described, and duplicate description will be omitted.

FIG. 6 is a bottom view showing the abduction pillow 101 of the present embodiment. In the abduction pillow 101, the lid is not attached to the main body 110. Further, cushion portions 111 that help the wearer to hold the lateral decubitus position are provided on the left and right sides of the main body 110. The portion of the main body 110 excluding the cushion portion 111 has substantially the same shape as the main body 10 of the first embodiment.

The cushion portion 111 has a structure that can be deformed according to the shape of the outer surface of the object to be contacted, and can maintain the deformed shape to some extent. Specific examples of the structure of the cushion portion 111 include a bead cushion, an elastomer, and various gel-like materials.

FIG. 7 schematically shows a state in which the wearer wearing the abduction pillow 101 is in the lateral decubitus position. If the left and right sides of the main body of the abduction pillow are curved, it may be difficult to hold the lateral decubitus position because the main body 110 is difficult to stand on its own in the lateral decubitus position. Of the cushion portions 111 provided on the left and right sides of the main body 110, the cushion portion 111 located on the lower side in the lateral decubitus position is deformed along the floor surface. As a result, one of the left and right side surfaces of the main body 110 is deformed to be flat or substantially flat, and the main body 110 is easily stabilized in the lateral decubitus position.

According to the abduction pillow 101 of the present embodiment, similarly to the abduction pillow 1 of the first embodiment, the wearer can easily change his / her body position while appropriately maintaining the abduction state of the wearer's legs. be able to. Further, the posture can be suitably stabilized even when the patient is in the lateral decubitus position.

In the present embodiment, an example in which the left and right side surfaces of the main body can be deformed to be flat or substantially flat by providing the cushion portion has been described, but the configuration for stabilizing the lateral decubitus position is not limited to this. For example, the left and right side surfaces of the main body may be formed flat in advance. Even in this case, the wearer can easily return to the supine position by shifting the weight while obtaining the effect of stabilizing the lateral decubitus position.

Although each embodiment of the present invention has been described above, the technical scope of the present invention is not limited to each of the above embodiments, and the combination of components may be changed without departing from the spirit of the present invention. Various changes can be made to or deleted from the components.

For example, the main body may be formed in a bag shape, and air may be introduced during use to inflate the main body into a shape when worn. In this case, the abduction state can be suitably maintained by applying a constant internal pressure during use while facilitating carrying by removing air when not in use.

Furthermore, the application target of the abduction pillow of the present invention is not limited to the above-mentioned postoperative hip joint replacement. The abduction pillow of the present invention can be suitably applied to other diseases that require maintenance of the abduction state of one or both legs of the patient.
