The present application provides a novel infusion set which enables a easy setting up of a standard order of use, the infusion set having a first member as a main tube and a second member as a branch tube, which are inserted into caps for priming by a simple step without causing liquid leakage. The cap is provided with a port and a lid, wherein the port has a hydrophobic filter arranged on an inner side of a front end relative to a three way stopcock joining connector or a drip needle joining connector inserted to the cap so as to pass out gas, but not liquid and solid and the lid, which is outside the port, is for closing the port. Further, the first member and the second member can be arbitrarily connected with the three way stopcock 5 for better usability. Moreover, stability of the infusion set and drip stands by applying any color, prevention of liquid leakage from an insertion site of a drip needle and patient’s physical discomfort, and prevention of incidents caused by wrong administration order are provided.本發明中提供一種容易訂定標準使用順序之新穎輸液組,其係包括構成主管之第1構件及構成支管之第2構件,且該輸液組係套有管套而可無液體滲漏並以簡便的步驟充液,該管套配置有在較由插入口插入管套內的對三分支旋塞之連接用接頭或點滴針連接用接頭的前端部更內側之部位配置疏水性過濾器使管套內之氣體通過但不使液體及固體通過之開口部、及在該開口部外側用以關閉該開口部之蓋,其中,可將第1構件與第2構件藉由三分支旋塞5而任意地連接並提高作業性,藉由任意地施加上色彩,可保持輸液組及點滴架的安定性、防止插入點滴針之部位滲漏液體及患者肉體上的痛苦、及防止發生起因於投予順序的人為疏失之事故。1‧‧‧用以安裝在瓶針之管套2‧‧‧瓶針3‧‧‧管夾4‧‧‧輸液軟管5‧‧‧三分支旋塞5a‧‧‧主管上游側接頭5b‧‧‧主管下游側接頭5c‧‧‧支管側接頭(無針式接頭)5d‧‧‧旋塞6‧‧‧用以安裝在對三分支旋塞之連接用接頭之管套6a‧‧‧對三分支旋塞之連接用接頭之插入口6b‧‧‧疏水性過濾器6c‧‧‧開口部6d‧‧‧蓋6e‧‧‧對三分支旋塞之連接用接頭7‧‧‧用以安裝在點滴針連接用接頭之管套7a‧‧‧點滴針連接用接頭插入口7b‧‧‧疏水性過濾器7c‧‧‧開口部7d‧‧‧蓋8‧‧‧公接頭9‧‧‧點滴筒10‧‧‧管鉗11‧‧‧過濾器袋12‧‧‧點滴針連接用接頭
