The present invention relates to a syringe for preparing an injectable solution and a sterile packaged sap that is packaged together with a sachet or even a vial.According to an embodiment of the present invention, there is provided a socket for preparing a liquid preparation for injection, comprising a body and a perforation unit slidably inserted in the body. The main body comprises a vial connecting portion and a port connecting portion communicating with the vial connecting portion. The vial connecting portion includes a vial side peripheral wall for partitioning the vial insertion passage, a bottom wall formed at the lower end of the vial side peripheral wall so as to close the lower end of the vial insertion passage, And a retaining hole formed through the periphery of the bottom wall connected to the guide portion. The port connection portion includes a port side wall which projects from the bottom wall of the vial connecting portion so as to define the port insertion passage and extends in a direction opposite to the direction in which the peripheral wall of the vial is extended, And a port side elastic piece having a lower end connected to the lower side of the port side opening. The perforation unit includes a base portion which is fitted in the vial insertion passage so as to be slidable along a guide portion provided in the vial connection portion, and a guide portion provided in the base portion and bi-directionally inserted into the guide portion of the bidirectional needle and vial connection portion And a guide corresponding portion formed around the base portion so as to correspond thereto.본 발명은, 주사액 혼합 제조용 소켓과, 이 소켓이 수액백과 함께 또는 약병까지 포함하여 멸균 포장된 수액 제품에 관한 것이다.본 발명의 일 실시예에 따른 주사액 혼합 제조용 소켓은, 본체 및 본체 내에 슬라이드 이동 가능하게 삽입되는 천공유닛으로 구성된다. 본체는, 약병 접속부 및 이와 연통되는 포트 접속부로 이루어져 있다. 약병 접속부는, 약병 삽입 통로를 구획하는 약병측 둘레벽과, 약병 삽입 통로의 하단을 폐색하도록 약병측 둘레벽의 하단에 형성되는 저벽과, 약병측 둘레벽의 상하 방향으로 뻗도록 약병측 둘레벽의 내면에 형성되는 가이드부 및 가이드부와 연접되는 저벽의 둘레부분에 관통 형성되는 걸림구멍으로 구성된다. 포트 접속부는, 포트 삽입 통로
