Abstract
본 발명은 유기농 면을 활용한 유아용 쿠션을 제공한다.The present invention provides a cushion for children using organic cotton.
Description
본 발명은 유기농 면을 활용한 유아용 쿠션에 관한 것이다.The present invention relates to a cushion for children using organic cotton.
현재 신생아용/유아용 쿠션으로 다양한 제품이 시장에 판매되고 있으며 이하에서는 그 유형에 대하여 설명하도록 한다. 이하에서의 용어 '유아'란 사전적 의미로 생후 1년부터 만 6세까지의 어린아이를 의미하나, 본 명세서에서 사용하는 유아란 생후 1년 미만의 신생아도 포함하는 개념으로 이해한다.Currently, various products are being sold on the market as cushions for newborns/infants, and the types will be described below. The term 'infant' hereinafter refers to a young child from 1 year of age to 6 years of age in the dictionary, but the term 'infant' as used herein is understood to include newborns less than 1 year of age.
먼저, 역류 방지 쿠션은 소화기관이 완전히 발달하지 못한 시기 유아의 역류성 위장장애 예방을 위하여 머리쪽 경사를 높여주어 유아 소화불량을 방지하는데 도움을 주는 쿠션이다. 또한, 수유 쿠션이란 유아 수유 시 유아를 눕혀 보호자와 유아가 가까이 위치하도록 하여 수유의 편리함 및 유아의 포근함을 느끼게 해주는 쿠션이다. 그리고, 출생 후 약 100일이 지나면 유아가 누워있는 상태에서 양팔을 이용하여 몸을 뒤집으려는 욕구가 생기며, 이 때 몸을 뒤집을 상태에서 원 자세로 다시 뒤집지 못하여 유아 호흡기가 이불 등에 파뭍여 질식하게 되는 영아 돌연사 증후군(SIDS; Sudden Infant Death Syndrome)이 발생 가능하며, 이를 방지하기 위하여 유아의 신체 양 옆에 쿠션 등의 보조장치를 이용하여 유아가 자신의 몸을 뒤집지 못하게 예방해주는 쿠션으로 뒤집기 방지 쿠션이 있다. 또, 신생아 시기에 유아의 몸을 압박하여 태아 시기에 비좁은 엄마 뱃속에 있는 느낌을 주게 하여 포근함과 안정감을 주는 것으로 중력 이불이 있다. 마지막으로, 유아에게 안락감을 제공하고 위생성을 향상시킬 목적으로 유모차의 탑승공간이나 자동차의 유아용 안전시트에 별도의 시트커버를 장착하여 사용할 수 있다.First, the anti-reflux cushion is a cushion that helps prevent indigestion in infants by increasing the head tilt to prevent reflux gastrointestinal disorders in infants when their digestive organs are not fully developed. In addition, a nursing cushion is a cushion that allows the infant to lie down when feeding an infant so that the guardian and the infant are close together, making feeding convenient and the infant feel cozy. Approximately 100 days after birth, the infant develops a desire to turn over using both arms while lying down. At this time, the infant's respiratory tract becomes trapped in the blanket, causing suffocation due to the inability to turn over to the original position. Sudden Infant Death Syndrome (SIDS) can occur, and to prevent this, auxiliary devices such as cushions are used on both sides of the infant's body to prevent the infant from turning over. there is. In addition, there is a gravity blanket that compresses the infant's body during the newborn period, giving the baby a feeling of being in a cramped belly during the fetal period, providing warmth and stability. Lastly, for the purpose of providing comfort to infants and improving hygiene, a separate seat cover can be installed and used in the riding space of a stroller or in the infant safety seat of a car.
본 발명의 목적은 유기농 면을 활용한 유아용 쿠션을 제공하는 것이다.The purpose of the present invention is to provide a cushion for children using organic cotton.
본 발명의 다른 목적은 항균 기능성이 우수한 친환경 시트를 포함하는 유아용 쿠션을 제공하는 것이다.Another object of the present invention is to provide a cushion for children including an eco-friendly sheet with excellent antibacterial functionality.
본 발명의 과제는 이상에서 언급한 과제들로 제한되지 않으며, 언급되지 않은 또 다른 과제들은 아래의 기재로부터 당업자에게 명확하게 이해될 수 있을 것이다.The object of the present invention is not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.
