description	The utility model provides a body fluid collector which comprises an injector, a needle head body and a valve, the injector comprises a needle cylinder and a piston rod, the piston rod is in sliding fit with a cylinder cavity of the needle cylinder, negative pressure is formed in the cylinder cavity when the piston rod slides along a first direction relative to the needle cylinder, and the pistonrod is in sliding fit with the needle cylinder. The piston rod can be locked relative to the needle cylinder so as to limit the piston rod to slide along a second direction opposite to the first direction; the needle body is connected with the needle cylinder; and the valve is connected with the needle head body or the needle cylinder to control the connection and disconnection between the needlehead body and the cylinder cavity. The collector can reduce the operation difficulty when body fluid is collected by one hand. 本实用新型提供了一种体液采集器，体液采集器包括注射器、针头本体以及阀门，注射器包括针筒以及活塞杆，活塞杆与针筒的筒腔滑动配合，当活塞杆相对于针筒沿第一方向滑动时，筒腔内形成负压，且活塞杆能够相对于针
