Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a conservative treatment for alleviating a disorder caused by hip arthrosis, particularly dislocation hip arthropathy, or a structure of an appliance for preventing the same.
[0002]
[Prior art]
Osteoarthritis in Japan is said to be 90% secondary due to the underlying disease, and more than 70% is dislocation hip. It is characterized by pain during exercise, limited mobility, and lameness caused by walking or standing behavior, and is characterized by degenerative degeneration of articular cartilage and reactive bone growth. Among them, it can be said that the biggest problem for patients is "pain", and it tries to avoid the pain that occurs in the hip joints, and it affects each part of the body, causing buttocks pain, thigh pain, sometimes upper knee pain It is not uncommon to sue. In addition, the movement limitation and lameness of the hip joints tend to increase with the increase in pain. The treatment includes conservative treatment and surgical treatment, and is determined in consideration of age, degree of symptom progression, presence / absence of bilateral morbidity, occupation and sex.
[0003]
Of these, the conservative treatment is performed even when the surgical treatment is not preferable or the progression is slowed down due to the elderly or other reasons, but it is a treatment for a mild disorder. Basically, while continuing to wear the brace to relieve pain, appropriate rehabilitation (for example, training for raising the lower limbs in the lateral position and the supine position) is often performed to increase muscle strength.
[0004]
[Problems to be solved by the invention]
At present, however, there are no effective devices to be worn on the hip joint, and many of the devices cannot be satisfied satisfactorily, not only for the therapeutic effect (improvement effect on disability), but also for the primary purpose of alleviating pain. This is because the hip joint has a shape that differs greatly between the standing position and the sitting position, but it is difficult to maintain an appropriate holding force while following the change in the shape (described later), and this may be an obstacle to stool. In many cases, since it is not an inflammatory disease, pain does not occur at rest and often appears strongly when it begins to move. For such people, the wearing operation itself is painful, and wears a device using metal or hard plastic This is considered to be caused by the fact that it is too bulky and wears and looks bad. Therefore, orthosis is prone to be avoided, and it can be dealt with in a way that hardly contributes to the improvement of arthropathy itself, such as using a walking stick (in some cases crutches) when walking and only administering analgesics when pain appears. There were many.
[0005]
Although the shape of the hip joint differs greatly between the standing position and the sitting position, it will be described in detail that it is difficult to maintain an appropriate holding force while following the shape change. The hip joint orthosis is basically in the same form as a supporter or corset for low back pain, that is, a belt-like one that circulates around the body, and joint pain can be reduced by tightening the left and right greater trochanters. However, while the place where the supporter and corset of back pain are tightened does not change greatly when the hip is extended and bent, the hip orthosis that wraps around the body while covering the left and right greater trochanters is near the lower pubic bone and the rear It passes through the vicinity of the rear end of the hip, and when the hip joint is bent, the most bent part is the front part of the brace and the most extended part is the rear part of the brace. Therefore, when a hip joint orthosis is manufactured and worn with the same structure as the lumbago orthosis, the front part is bent each time a posture such as sitting on a chair is taken, and an inferior wearing feeling is experienced. However, if you try to eliminate this drawback by adopting a flexible, thin and excellent stretchable material, the tightening force naturally becomes weak and it is difficult to increase the effect.
[0006]
[Means for Solving the Problems]
Therefore, the present inventor has finally made the present invention as a result of intensive studies in view of the above points, and the feature thereof is a stretchable sheet-like flexible device composed of a buttocks portion and a belt portion, The bottom surface of the buttocks projectingly projects, and at least the vicinity of the lower end of the projecting portion forms a curved surface, and the belts extend from the left and right ends of the buttocks respectively. It is in the point formed by a main body and the latch attached to the front-end | tip of each belt main body.
[0007]
In other words, the orthosis of the present invention is a hip joint orthosis that is fixed by rotating around the front side of the body while applying the buttocks to the buttocks and pulling the belt portions at both ends. Since there are two belts on each of the left and right sides, the vicinity of the front thigh root, which is the most bent portion when the hip joint is in the bent position, is opened. Therefore, even when seated on a chair, it is not necessary to feel much cramped. In addition, since the lower surface of the buttocks overhangs and forms a curved surface, when wearing the device of the present invention on the underwear and wearing the outerwear from above, wear along the body line It is not so noticeable, and when it rises from the chair, there is almost no displacement of the brace due to the presence of this curved portion when the stretched buttocks rest to return. Therefore, “re-tightening” becomes almost unnecessary after being mounted once.
[0008]
The orthosis of the present invention is composed of two parts, a “butt rest part” and a “belt part”. These are all in the form of a sheet having elasticity, and need not be constituted by separate members. Usually, a piece of stretchable fabric is cut and then stitched or other processing is added to obtain a product.
[0009]
For example, when cutting the flat cloth to make the buttocks, to cut the bottom surface of the buttocks, cut the lower end into one or several V-shapes, and then sew the notch portion; For example, installing a hook-and-loop fastener to fix the circulated belt corresponds to this processing. In addition, processing for providing anti-slip means may be performed in order to prevent the orthosis from shifting during daily operations and impairing the therapeutic effect or deteriorating wearing comfort. This anti-slip means is preferably provided in the vicinity of the portion that contacts the tip of the greater trochanter, and it is effective to provide silicone resin as an anti-slip pad here. In that case, this anti-slip pad may adopt a technique in which a molten silicone resin is applied and cured, or several types of pads having different shapes and thicknesses are prepared as separate members and of an appropriate size. You may be able to hang up and adjust to your symptoms.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the drawings.
[0011]
FIG. 1 shows an example of a hip arthrosis device 1 according to the present invention (hereinafter referred to as the present device 1). The present device 1 has a portion called a buttocks portion 2 and longitudinal directions from both ends thereof. It is a substantially flat sheet-like body composed of a pair of belts 3 (that is, four belts) extending in a straight line. A hook-and-loop fastener 4 is sewn near the tips of two of the four belts 3. In the case of this example, the buttocks rest part 2 and the belt 3 are not separate members, but are formed by cutting and sewing one piece of fabric. The cloth used is a polypropylene fiber yarn knit product (trade name “Pyrene”: manufactured by Toray Industries, Inc.) with at least one surface raised, which is slightly stretchable, tough and commercially available. It can be said that it is a suitable material for the present invention because it can be easily and reliably locked when the male side of a conventional hook-and-loop fastener is brought into contact with the raised surface.
[0012]
Further, the lower part of the buttocks 2 is overhanging (the overhanging portion is indicated by hatching), and a curved portion 5 is formed in this portion. The curved portion 5 is a portion that is formed at the same time when the above-mentioned single piece of fabric is cut and sewn. The lower end central position of the fabric is cut out in a V shape, and is sewn in a state where the gap is close. can get. In the illustrated example, there is only one cut-out stitched portion, but if the number is two or more, the curved portion 5 having a higher degree of curvature can be obtained (not shown).
[0013]
Further, on the left and right ends of the back surface of the buttocks 2 (the surface that becomes the inner side when worn), there are provided anti-slip pads 6 formed by applying a solid silicone rubber melt in an oval shape and solidifying it. Due to this presence, the orthosis 1 of the present invention can be prevented from shifting in daily operations, and the effect can be suitably maintained. The anti-slip pad 6 of this example is a silicone resin applied to the fabric forming the buttocks 2 and is easy to handle, but is difficult to replace or remove. Therefore, the anti-slip pad 6 may be a separate body and provided with a hook-and-loop fastener or the like so that it can be freely attached and detached. Furthermore, if several types of shapes and thicknesses of this pad are prepared, it becomes a suitable appliance (not shown) that can accurately cope with the body shape and the healing stage of symptoms.
[0014]
2 (a) and 2 (b) show an example of the usage state of the device 1 of the present invention. The mounting is only performed by placing the buttocks abutment portion 2 against the heel portion in the standing position (state shown in FIG. 1 (a)), pulling the left and right belts 3 and locking the hook-and-loop fasteners 4 at their tips to the body. Since the bending portion 5 of the device 1 of the present invention extends along the lower side of the heel portion, even if the device 1 of the present invention is shifted upward due to daily operations, the bending portion 5 prevents it. In particular, in the case of this example, since the anti-slip pad 6 is just at the greater trochanter head position 7, even in a state where it is seated on a chair [state of FIG. The shape of the orthosis 1 of the present invention varies greatly in daily operations, unlike the case of a lumbago device, but the belt 3 exists in a form that separates up and down across the body bending portion. Even in the state of b), there is no discomfort. Further, although the orthosis 1 of the present invention is fixed in a tensioned state, the bending portion 5 exists in an overhanging portion that is not greatly affected by the tensile force of the belt 3. It is not difficult to bend the vicinity. Therefore, for example, in the case of stool, it is possible to add use without removing the brace.
[0015]
【The invention's effect】
As described in detail above, the hip joint device according to the present invention is a stretchable sheet-like soft device composed of a buttocks portion and a belt portion, and the bottom surface of the buttocks portion projects and At least the vicinity of the lower end of the overhanging portion is curved, and the belt portion extends from the left and right ends of the buttocks portion by two each, and a latch that is attached to the tip of each belt main body The invention is an extremely advanced invention having various effects as described below.
[0016]
(1) Since it is a sheet-like flexible appliance that does not use metal support or the like, it is not bulky even if it is worn, and long-term wearing including going out can be done without difficulty.
(2) Since it is wound around the greater trochanter, its shape changes greatly in daily operations, but the left and right belts each have a pair above and below the greater trochanter, so the shape changes when bent Follow without any discomfort.
(3) Since a curved part is formed below the buttocks, the device of the present invention is prevented from shifting upward.
