Detailed Description

The first embodiment is as follows: referring to fig. 1-4, the dual-connector anti-reflux fluid specimen collecting and draining device includes a connector assembly 1, a drainage tube 2 and a drainage bag 3;

the joint assembly 1 comprises an inner joint 101 and an outer joint 102; the upper end of the nipple 101 is provided with an internal thread connector 1011, the lower end of the nipple 101 is communicated with one end of the drainage tube 2, and one end of the drainage tube 2 far away from the nipple 101 is communicated with the drainage bag 3; the female threaded interface 1011 on the nipple 101 can be connected with a threaded interface on another drain tube 2.
