Abstract
Description
[Technical field]
[0001] The present invention relates to a skull shape guide helmet for guiding the skull shape to correct skull deformation in infants and young children. [Background technology]
[0002] Infants' skull shapes can become distorted due to factors such as sleeping habits, resulting in cranial deformations such as plagiocephaly, brachycephaly, and dolichocephaly. Plagiocephaly is a head shape in which one side of the head is flat and appears asymmetrical when viewed from the top of the head. Infants who have a strong tendency to sleep to one side or the other are prone to plagiocephaly. Brachycephaly is a head shape in which, when viewed from the top of the head, the head appears shorter from front to back compared to its width. Infants who often sleep on their backs are prone to brachycephaly. Dolichocephaly is a head shape in which, when viewed from the top of the head, the head appears longer from front to back compared to its width. Infants who often sleep on their side are prone to dolichocephaly.
[0003] In order to correct these cranial deformations, cranial shape induction helmets are used. Various types of cranial shape induction helmets have been developed (Patent Documents 1, 2, 3). Since cranial shape induction helmets are worn continuously on the heads of infants and small children for several months, they are required to be lightweight, have a hard outer shell for inducing the skull shape, have a cushioning lining on the inside of the shell to prevent the head from being injured, and be able to adjust the size to a certain extent in accordance with the growth of the infant's skull, and the cranial shape induction helmets proposed so far generally meet these requirements.
[0004] However, because the helmet is worn continuously on the head as described above, there are problems such as sweating due to humidity causing heat rash, and dirt and odors accumulating inside the helmet. Furthermore, because the skull of an infant continues to grow while wearing the helmet, parts of the head are strongly pressed against the inside of the helmet, causing head injuries even if there is a cushioning lining.
[0005] The skull correction helmet described in Patent Document 4 attempts to solve the problem of sweating by using a highly water-absorbent and quick-drying material for the cushioning lining (interior material). However, it cannot eliminate the accumulation of dirt caused by sweat.
[0006] The skull shape correction helmet described in Patent Document 5 is intended to solve the problem of contamination caused by sweating. It consists of a hard outer shell and a soft inner liner, which is made up of multiple liner pieces, each of which can be attached and detached independently. When the liner becomes contaminated due to sweating or the like, only the contaminated liner piece can be replaced with a new one, not the entire liner, which is economical. However, it is thought that this does not assume that the liner pieces will be replaced on a daily basis.
[0007] Although the helmets in Patent Documents 1 to 5 are all adjustable in size, they require the helmet to be removed from the baby's head in order to adjust the size, and they do not have the function of automatically expanding or contracting in size to match the growth of the baby's skull while wearing the helmet. Therefore, there is a risk that the baby's head may be strongly pressed by the helmet as it grows while wearing it, resulting in injury. [Prior art documents] [Patent documents]
[0008] [Patent Document 1] Patent Publication 2014-169510 [Patent Document 2] Patent Publication No. 2019-178462 [Patent Document 3] Patent No. 2022-73089 [Patent Document 4] Patent Publication 2015-183330 [Patent Document 5] Patent Publication No. 2022-017025 Summary of the Invention [Problem to be solved by the invention]
[0009] To provide a skull shape guidance helmet that is free from the risk of developing miliaria due to sweating while being worn, that does not allow dirt or odors to accumulate inside the helmet due to sweating, and that does not cause head injuries due to the growth of the skull of an infant or small child while being worn. [Means for solving the problem]
[0010] After extensive research, the inventors of the present invention came to the conclusion that attaching a water-absorbent cloth liner to the inside of the helmet would be an effective solution to the problem of sweating. The liner can be easily put on and taken off like underwear, and multiple liner pieces can be prepared and replaced every day or any number of times a day, and can be reused after washing and drying. The material for the liner can be any water-absorbent fiber, and cotton, rayon, polyester, acrylic, etc. are suitable, with 100% polyester being particularly suitable.
[0011] As an example of the shape of the helmet and the inner liner to make them easier to put on and take off, the inner liner is shaped like a dome when worn by an infant, with four slits formed on the edge. The helmet body has protrusions in the areas in front and behind the wearer's ears when worn, and the inner liner is attached to the helmet body by fitting these protrusions into the slits in the inner liner.
[0012] Also, a mechanism is provided to fasten the inner layer to the helmet body so that the attached inner layer will not easily come off due to the movements of the baby. One example of this is to attach a hook-and-loop fastener to the edge of the inner layer that faces the outer surface of the helmet when attached to the helmet, and also to attach a hook-and-loop fastener to the part of the outer surface of the helmet body that faces the edge of the inner layer. The inner layer and the helmet body can be fixed by bonding the hook-and-loop fastener on the edge of the inner layer to the hook-and-loop fastener on the helmet body.
[0013] Furthermore, the inventor of the present application came up with the idea that it is possible to prevent head injuries caused by the growth of the skull of an infant wearing the helmet by providing a mechanism for expanding the inner circumference of the helmet in accordance with the growth of the skull of the infant wearing the helmet. As an example of a mechanism for expanding the inner circumference of the helmet in accordance with the growth of the skull while maintaining the function of inducing the skull shape, the helmet body is divided into a front part and a rear part, and the front part and the rear part are joined at two points that are above the left and right ears of the wearer. At one of the two points, both sides are joined with a screw to fix it so that it does not move while wearing the helmet. At the other point, the front part and the rear part of the helmet body are joined with an elastic belt. At this point, as the skull of the infant wearing the helmet grows, the belt expands, causing the front part and the rear part to slide against each other, expanding the inner circumference of the helmet body. Therefore, the head of the infant wearing the helmet is not injured.
[0014] The position of the connection points that connect the front and rear parts of the helmet body is also important. If the helmet is connected in a similar manner near the top of the head, even if it is connected to maximize the size, the helmet will mainly expand in depth and the inner circumference will expand only slightly. In the present invention, by providing connection points approximately 3 cm above the bottom end of the part that faces the upper side of the wearer's left and right ears, the inner circumference of the helmet will expand when the helmet is connected to expand it.
[0015] The skull shape guiding helmet of the first invention has a helmet body and an inner layer made of absorbent cloth that can be attached and detached to the helmet body, and is characterized in that the helmet body has a hard shell and a cushioning material adhered to the inside of the shell, and is composed of a front side and a rear side.
[0016] The cranial shape guiding helmet of the second invention is a cranial shape guiding helmet of the first invention, characterized in that the front and rear parts of the helmet body have connecting parts on the left and right sides, respectively, and one of the left and right connecting parts allows the front and rear parts to be slidably connected while the wearer is wearing the helmet.
[0017] The skull shape guiding helmet according to the third invention is the skull shape guiding helmet according to the second invention, characterized in that in one of the left and right connecting parts, a plurality of holes are engraved in a horizontal line approximately 3 cm above the lower end of the part of the front part of the helmet body that faces the upper side of the wearer's ear, and one screw receiver is provided approximately 3 cm above the lower end of the part of the rear part that faces the upper side of the ear, and the front and rear parts can be fixed by passing a screw receiver of the rear part through any of the plurality of holes of the front part, fitting a screw into the screw receiver and tightening the screw, and in the other of the left and right connecting parts, a belt made of an elastic material and having a hook-and-loop fastener on the surface facing the helmet body is fixed in the approximately horizontal direction approximately 3 cm above the lower end of the part of the outer surface of the front part that faces the upper side of the wearer's ear, and a hook-and-loop fastener is attached to the part of the rear part that faces the belt, and the front and rear parts are slidably connected by adhering the hook-and-loop fastener of the belt to the hook-and-loop fastener of the rear part.
[0018] The cranial shape guiding helmet of the fourth invention is a cranial shape guiding helmet of any of the first to third inventions, characterized in that when the front and rear of the helmet body are joined, it has two protrusions on each side of the parts that correspond to the front and back of the wearer's ears, and the inner has slits in the parts corresponding to the protrusions, and it is attached to the helmet body by fitting the protrusions corresponding to the slits.
[0019] The skull shape guiding helmet of the fifth invention is a skull shape guiding helmet of the fourth invention, characterized in that the inner has a hook-and-loop fastener on the edge, and the helmet body has a plurality of hook-and-loop fasteners on the outer surface above the base of the protrusion, and the inner is fixed to the helmet body by adhering the hook-and-loop fasteners of the inner to the hook-and-loop fasteners of the helmet body. Effect of the Invention
[0020] The skull shape guiding helmet of the present invention eliminates the risk of prickly heat caused by sweating while worn by infants, prevents the accumulation of dirt and odors on the inside of the helmet due to sweating, and eliminates the risk of head injuries caused by the growth of the infant's skull while wearing the helmet.
