Description

TECHNICAL FIELD The present invention relates to a trunk orthosis to be worn on the trunk.

As a treatment for a compression fracture of the spine, a trunk brace may be used to limit the movement of the spine, especially forward bending, and fix the fracture site. Main types of trunk braces include metal braces made by bending a metal frame such as aluminum to fit the dimensions of the wearer's body (see, for example, Patent Document 1), and braces that take the shape of the wearer's body. There are hard braces made by making a gypsum model and bending resin to match the shape of the model, and soft braces made by sewing a mesh fabric or the like according to the size of the wearer's body. Since soft braces are inferior to metal braces and hard braces in fixation force of fracture sites, metal braces or hard braces are often used immediately after vertebral compression fractures.

In general, the wearer needs to keep wearing the trunk brace except when bathing during the treatment period of about 3 months. Metal braces and rigid braces have a structure in which the wearer's body is covered with a metal frame or resin, and therefore, many wearers feel that they have a heavy appearance and are reluctant to wear them. In addition, it is desirable in treatment to wear a trunk brace as early as possible after a vertebral compression fracture occurs. However, metal braces and hard braces need to be manufactured by bending metal or resin individually according to the body dimensions of each wearer in order to sufficiently fix the fracture site. It's taking time.

Therefore, in recent years, there has been an increasing demand for a jewel type brace, which is a type of metal brace (see, for example, Patent Document 1). The Jeuette-type brace is a brace that has a frame structure that fixes three points, the chest, back, and lower abdomen. The feeling of weight is small, and it is easily accepted by the wearer. Another advantage of Jeuette-type braces is that they can be adjusted to fit the wearer's body by adjusting the height and bending of the frame, so delivery does not take much time.

A trunk orthosis according to an embodiment of the present invention includes a pair of lumbar pads positioned on both sides of the waist, a chest pad positioned on the chest, a back pressure part positioned on the back, and a pair of lumbar pads positioned on the outside. The waist belt covers the anterior superior iliac spine, and the interval between the pair of lumbar pads on the abdominal side is 1/3 or more of the interval between the left and right anterior superior iliac spines. The waist belt is characterized in that it is offset to the opposite side of the wearer on the abdomen side of the portion located between the pair of waist pads.

FIG. 1 is a front view of a trunk brace 1 according to an embodiment of the present invention, FIG. 2 is a rear view of the trunk brace 1, and FIG. 3 is a right side of the trunk brace 1. It is a view. As shown in FIGS. 1 to 3, the trunk brace 1 includes a pair of waist pads 10 positioned on both sides of the waist, a chest pad 20 positioned on the chest, and a back pressing portion 30 positioned on the back. and a waist belt 40 located outside the waist pad 10 of the body.

The waist pads 10 are positioned on both sides of the waist of the wearer of the trunk brace 1 and are a pair of left and right. That is, the waist pad 10 has a right waist pad 10R and a left waist pad 10L. In the present invention, the right side is the right side seen from the wearer of the trunk brace 1, and the left side is the left side seen from the wearer.

Lumbar pad 10 covers the anterior superior iliac spine. That is, the right lumbar pad 10R covers the right anterior superior iliac spine of the wearer of the trunk brace 1, and the left lumbar pad 10L covers the left anterior superior iliac spine.

The material forming the waist pad 10 is preferably elastic synthetic resin. Materials constituting the waist pad 10 include, for example, polyurethane-based resins, polystyrene-based resins, polyolefin-based resins, and the like. Among them, the material constituting the waist pad 10 is more preferably a foamed resin, more preferably a foamed polyolefin resin, and particularly preferably a foamed polyethylene. By configuring the waist pad 10 in this way, the flexibility of the waist pad 10 can be enhanced, and the waist pad 10 can be brought into close contact with the waist of the wearer of the trunk brace 1 . Furthermore, when the waist pad 10 comes into contact with the waist of the wearer, the wearer is less likely to feel discomfort such as pain.

The maximum thickness of the waist pad 10 is preferably 5 mm or more, more preferably 10 mm or more, and even more preferably 15 mm or more. By setting the lower limit of the maximum thickness of the waist pad 10 in this manner, the cushioning property of the waist pad 10 can be made sufficient. Also, the maximum thickness of the waist pad 10 is preferably 50 mm or less, more preferably 40 mm or less, and even more preferably 30 mm or less. By setting the upper limit of the maximum thickness of the waist pad 10 in this way, the trunk brace 1 is less conspicuous in appearance when worn, and when wearing clothes with the trunk brace 1 attached, the trunk brace 1 can be easily worn. 1 becomes less likely to interfere with wearing clothes.

The chest pad 20 is positioned on the chest of the wearer of the trunk brace 1 . Since the trunk brace 1 has the chest pad 20, it is possible to fix the chest of the wearer of the trunk brace 1 and prevent the wearer from bending forward. As a result, it is possible to prevent a load from being applied to the spine of the wearer of the trunk brace 1 and sufficiently fix the fracture site.

The material forming the chest pad 20 is preferably an elastic synthetic resin, and examples thereof include polyurethane-based resin, polystyrene-based resin, polyolefin-based resin, and the like. Among them, the material constituting the chest pad 20 is more preferably a foamed resin, more preferably a foamed polyolefin resin, and particularly preferably a foamed polyethylene resin. Since the chest pad 20 is configured in this manner, the chest pad 20 is highly flexible, and while the trunk brace 1 is sufficiently attached to the chest of the wearer, it is difficult to cause discomfort such as pain. .

The maximum thickness of chest pad 20 is preferably smaller than the maximum thickness of waist pad 10 . By configuring the chest pad 20 in this way, the repulsive force of the chest pad 20 can be increased, and the wearer can be effectively prevented from bending forward.

As shown in FIG. 2, the chest pad 20 may have grooves on the wearer's side. By configuring the chest pad 20 in this way, the chest pad 20 can easily follow the chest of the wearer of the trunk brace 1, and the strength of fixing the chest can be increased.

The back pressing part 30 is positioned on the back of the wearer of the trunk brace 1 . Since the trunk brace 1 has the back pressing portion 30, the back of the trunk brace 1 is fixed to the wearer's back, thereby preventing the wearer's spine from being burdened and fixing the fracture site. can be increased.

The back pressing part 30 may be positioned on the back of the wearer, or may be positioned on the back side of the waist of the wearer. Above all, it is preferable that the back pressing part 30 is positioned on the wearer's back. Positioning the back pressing portion 30 at such a location can sufficiently increase the force supporting the back of the wearer.

The waist belt 40 is positioned outside the pair of waist pads 10 . The waist belt 40 can fix the right waist pad 10R and the left waist pad 10L in close contact with the waist of the wearer of the trunk brace 1 . As a result, the wearer of the trunk brace 1 is less likely to be in a forward bending posture, and it is possible to prevent a burden from being applied to the spine and increase the force for fixing the fracture site.

Materials for the waist belt 40 include synthetic fibers, natural fibers, leather, synthetic resins, natural rubber, and the like. Above all, the waist belt 40 preferably has a flat plate shape containing synthetic resin, and more preferably has a flat plate shape containing a thermoplastic elastomer such as a polyester-based resin or a polyurethane-based resin. By configuring the waist belt 40 in this manner, the durability of the waist belt 40 can be enhanced, and the waist belt 40 can be easily attached and detached repeatedly.

The space D1 on the abdominal side of the pair of lumbar pads 10 is 1/3 or more of the space between the left and right anterior superior iliac spines. That is, the distance between the right lumbar pad 10R and the left lumbar pad 10L on the abdominal side of the wearer of the trunk brace 1 is the right anterior superior iliac spine and the left anterior superior iliac bone of the wearer of the trunk brace 1. It is preferably 1/3 or more of the distance to the spine. By configuring the pair of waist pads 10 in this manner, the waist pads 10 sufficiently support the pelvis of the wearer of the trunk brace 1, while the area of contact between the waist pads 10 and the lower abdomen of the wearer is reduced. It is possible to make it smaller. Therefore, it is difficult for the wearer's abdominal pressure to increase excessively when wearing the trunk brace 1, and comfort during wearing can be improved.

The space D1 on the abdomen side of the pair of lumbar pads 10 may be 1/3 or more of the space between the left and right anterior superior iliac spines, but is preferably 35% or more of the space between the left and right anterior superior iliac spines. It is preferably 40% or more, more preferably 45% or more, and particularly preferably 50% or more (1/2 or more). By setting the lower limit value of the space D1 on the abdomen side of the pair of waist pads 10 in this manner, the area of contact between the waist pads 10 and the wearer can be further reduced, and the trunk brace can be made more comfortable. . Also, the pair of lumbar pads 10 need only cover the left and right anterior superior iliac spines, and the upper limit of the space D1 between the pair of lumbar pads 10 on the abdominal side is not particularly limited. It can be 95% or less, 90% or less, 85% or less of the barb spacing.

The waist belt 40 is offset to the opposite side of the wearer on the abdomen side of the portion located between the pair of waist pads 10 . In other words, the waist belt 40 is spaced apart from the wearer and floats between the right waist pad 10R and the left waist pad 10L on the abdominal side of the wearer of the trunk brace 1 . Since the waist belt 40 is configured in this way, the waist belt 40 does not easily press the lower abdomen of the wearer of the trunk brace 1, and the trunk brace 1 can be worn with less discomfort. is.
