Abstract

본 발명은 말단 부분이 다각-경사진(multi-beveled) 피하 주사 바늘에 관한다. 하나의 구체예에서, 상기 다각-경사진 말단은 주요 경사(primary bevel), 한쌍의 말단 경사, 및 각 부분이 주요 경사 및 말단 경사 각각을 연결시키는 한쌍의 중간 경사를 특징으로 한다.
상기 주요 경사 및 중간 경사는 경사각에서 제공되는데, 상기 경사각은 실질적으로 동일한 중심축 및 기준 평면 사이에서 측정된다. 상기 말단 경사는 상기 주요 경사 및 중간 경사가 제조된 경사각과 동일하지 않은 중심축에 대한 경사각에서 제조된다. 결과로 제조된 5각-경사진(five-beveled) 말단 형태는 각각의 경사면들 사이의 접합부 또는 급경사진 횡단면이 존재하지 않는 더욱 고른 경사면을 가지며, 상기 주사 바늘이 피부, 근육 또는 기타 재료를 관통할 때 요구되는 관통력(penetration forces)이 감소되었다.
