Description

Horizontal orthopedic brace

Technical Field

The invention relates to an orthopedic brace, which is used for improving head shape deviation and face shape asymmetry of infants caused by incorrect sleeping postures and can also be used for head shape deviation caused by torticollis and adjuvant therapy of torticollis.

Background

The improper sleeping posture of the infant causes the asymmetric development of the head at two sides, namely one side is too flat and the other side is swollen, and the asymmetric face shape (large face and small face) and the asymmetric forehead are caused, thereby affecting the occlusion of teeth and the amblyopia. The infant is in the period of fastest brain volume increase from birth to age 1 or so, the skull grows rapidly to meet the brain development requirement, early closure of cranial sutures or unbalanced external force can cause abnormal development of skull morphology during the period, the former is called craniosynostosis and needs surgical treatment; the latter is called developmental plagiocephaly and requires early orthopedic treatment.

A normal infant head is shown in fig. 1, while a typical developmental glancing head is shown in fig. 2: one side of the head (i.e. the head on the lower right side in fig. 2) is flattened due to long-term contact with the bed surface, and the opposite side of the head (i.e. the head on the lower left side in fig. 2, which are also called as the occiput in the field of brain) is raised, so that the corresponding positions of the auricles on both sides and the forehead of a badly deflected baby are not symmetrical. The highest point O of the head on the side which is more raised is connected with the frontal angle A on the opposite side, the highest point C of the head on the side which is more flat is connected with the frontal angle B on the opposite side, and on the maximum cross section (namely an axial tangent plane) of the skull, the difference value of the lengths of AO and BC represents the asymmetry of the skull, namely the severity degree of head deviation. For head shapes with a difference between AO and BC of more than 1 cm we need to correct.

The existing method for correcting developmental plagiocephaly of children focuses on two methods: adjusting common sleeping posture and correcting by a helmet. The common sleeping posture adjustment is to place the head of the baby at the opposite inclined position and gradually correct the deformity by the pressure of the self weight, however, the common sleeping posture adjustment is only effective for the children within 2 months of age, and the head of the baby is difficult to fix due to the fact that the baby turns over at night slightly, parents consume time and labor, and the correction effect is difficult to ensure.

Helmet correction refers to the wearing of a specially designed helmet that applies pressure to the site of the deformity protrusion, gradually correcting as the skull grows. However, the helmet correction is suitable for children with more than 6 months, needs to be continuously worn for 4-6 months in 24 hours, is poor in comfort level, is easy to cause skin eczema and other nursing problems due to moisture of sweat, needs to be customized from abroad, and is expensive;

in addition, the orthopedic helmets proposed in the prior art cannot correct facial deviation (large and small faces) caused by improper sleeping posture.

At present, for children from 2 months to 6 months, the correction means is vacant, but most developmental oblique heads attract the attention of parents at the moment, if the children cannot be corrected in time at the stage, the children can only be left in the right place, and no other options except for a correction helmet exist.

In order to overcome the disadvantages of the prior art and additionally to provide an auxiliary treatment for developing a diagonal head of an infant while treating the diagonal neck for a head deviation caused by the diagonal neck, the following solutions are proposed.

Disclosure of Invention

The invention provides a device and a method for correcting head shape deviation and face shape asymmetry of an infant caused by improper sleeping posture. The device comprises: a head-shaped concave part composed of a pressing surface and a releasing surface, wherein the pressing surface is in contact with the head part on the side with a relatively bulge, and the releasing surface is arranged at intervals with the head part on the side with a relatively flat; an integral postural support connected to the head-shaped concave member in such a way as to rotate the latter through a suitable axial angle about an axis perpendicular to the plane of the drawing of fig. 1 or 2 (i.e. the axis on which the neck of the infant is supposed to be) and to fix the head-shaped concave member, so that the flatter head of the infant is released and the bulging head is pressurized for the purpose of orthopedics as the head grows. Different from the prior art, the invention has the following functions: 1) the skull is guided to form a shape and develop by rotating the proper head position of the infant and enabling the pressurizing surface in the device to be in contact with the more protruding part of the skull, and the releasing surface to keep a proper distance with the flatter part of the skull; 2) the face asymmetry caused by improper sleeping posture is corrected by deflecting the head; 3) has adjuvant treatment effect on asymmetric infant with muscular torticollis.

A preferred construction is that the chest-back support is a one-piece postural support which forms a fixed angle of rotation with the concave head-shaped member, so that the weight bearing portion of the concave head-shaped member is fixed to the head on the side which is more swollen, thereby ensuring that the head is stressed in the manner described above.

A preferred construction consists in that the bed or the bed base is used as an integral postural support, which forms a fixed rotation angle with the head-shaped concave part, resulting in a product which is smaller in volume but has a greater resistance to rolling and translation than the former.

A preferred embodiment consists in selecting the axial rotation angle in such a way that: so that the line connecting the centre point of the more prominent side of the head to the contralateral frontal angle is oriented substantially vertically, in which case the more prominent side of the head is subjected to as much pressure as possible in the context of the weight of the head, so as to limit the growth of this region as much as possible and thus to guide the growth of a flat head. Of course, it is not a limitation that the line must be perpendicular to the horizontal plane, and such a rotation angle may be desirable if the more elevated side head can be subjected to relatively more force.

A preferred embodiment is also that the orthopedic brace can further comprise other components such as a neck support structure, an ear protection structure, a skin protection structure, preferably made of a soft material.

Furthermore, the medial side of the orthopedic support preferably has to be wrapped around at least half of the circumference of the skull, in particular from anterior tragus on one side to anterior tragus on the other side via the head.

A preferred arrangement is also such that the material of the body of the orthopedic brace is thermoplastic to allow at least one further adjustment of the structure of the orthopedic brace to accommodate the head shape if the infant's head changes after a period of adjustment.

The device can be of an integrated structure or formed by splicing the components, and the main material of the device is preferably moderate rigid, namely, a small amount of deformation is provided to increase the comfort level, and necessary supporting force is provided to ensure the orthopedic effect. Further preferably, the material is low-temperature thermoplastic plate or other moderate rigid material which is nontoxic to human body, the skin of the infant is not easy to be allergic, and the infant is easy to clean and has the capacity of reshaping for at least 1 time in the later period.

Detailed description of the invention

FIG. 3 is a schematic cross-sectional view of an embodiment of the present invention. Wherein the head pressure plane, the release plane, the head most-projected point on the side of more raised with O, O point and the frontal angle on the opposite side with A, the head most-projected point on the side of flatter with C, and the frontal angle on the opposite side with B are referenced. The correct corrective position is to orient the AO line in a vertical direction. The included angle a between the AO connecting line and the skull midline is an important parameter measured by a clinician, the shape of the head-shaped concave part 1 is usually obtained by a child who needs to be corrected, the skull inclination angle is adjusted according to the included angle a and other head shape parameters, and the process is finished by further trimming, reshaping, edge covering and the like. Among them, the head-shaped concave part 1 may be divided into: pressing surface (F1): the head support is used for being in fit contact with the head on one side of the relatively raised part, bearing the gravity of the skull and feeding back the supporting force; release surface (F2): for spacing from the side of the relatively flat head, preventing stressing of the skull there and thereby providing space for further growth of the skull there. The inclination angle of the whole skull should meet the following requirements: the most protruding point O of the head part on the more protruding side is positioned at the lowest point; the contralateral frontal angle A is positioned at the highest point of the whole skull; i.e. the AO-line is oriented substantially vertically. The inner side surface of the head-shaped concave part comprises at least one half of the skull perimeter, and specifically, the head-shaped concave part wraps the head from the front of the tragus on one side to the front of the tragus on the other side. The overall postural support structure 2 of the other orthopedic brace in figure 3: can be composed of a chest and back support or a bed support and is used for keeping the whole position of the structure, namely the inclination angle or the axial rotation angle a of the skull, unchanged along with the activity of the infant.

Fig. 4 is an overall side view of the preferred embodiment of the present invention, as shown, including the head-shaped concave part 1, the overall posture support structure 2, the neck support structure 3, the head adjustment patch 4, the ear protection structure 5, and the skin protection structure 6.

Neck support structure 3: the neck support structure 3 is not required to provide proper neck support, maintain proper physiological curvature of cervical vertebrae for infants, and provide proper axial rotation angle a for the head structure, but the whole posture support structure 2 can also perform the function without the neck support structure. Preferably, the head adjusting paste 4 is a sheet-shaped single-sided adhesive made of a soft material, and is pasted on the inner side surface of the head-shaped concave part to exert pressure on the protruding head and protect the locally pressed skin, and the number, the shape and the position of the head adjusting paste can be increased or decreased according to the change of the head shape during later adjustment, so that a better orthopedic effect is achieved. Ear protection structure 5: the delicate ear skin of the infant is protected from being pressed red or discomfort in the wearing process; skin protection structure 6: the key supporting position and the edge position of the brace are processed by soft materials, so that the brace is prevented from pressing, cutting and scratching the skin of the infant.
