Abstract

The invention relates to a needle cylinder sampling device which comprises a base, a sampling component, a rotary actuator and a controller. The base functions in supporting and fixing, the sampling component is mounted on the base and comprises a needle cylinder and a plug valve with an infusion port, a fluid preparation port and a plug for controlling opening or closing of the infusion port andthe fluid preparation port, and one end of the needle cylinder is communicated with the infusion port. The rotary actuator is mounted on the base and in transmission connection with the plug. The controller is electrically connected with the rotary actuator and used for receiving control signals and controlling the rotary actuator to drive the plug to rotate according to the control signals. The needle cylinder sampling device has the advantage of convenience in use.

Description

technical field [0001] The invention relates to the technical field of laboratory collection equipment, in particular to a syringe sampling device. Background technique [0002] At present, in the technical field of laboratory collection equipment, a syringe sampling device is usually used to sample and distribute the sample liquid. The syringe sampling device includes a syringe and a stopcock. The syringe can draw the sample liquid and distribute it to multiple specific devices through the stopcock for analysis and detection. The stopcock is arranged at one end of the syringe, and there are openings connected with the syringe and specific equipment respectively on it. By turning the cock of the cock valve, the opening or closing of the opening can be controlled to control the distribution of the sample liquid. [0003] Generally, the rotation of the cock needs to be driven by manpower, which causes troublesome operation and inconvenient use. Contents of the invention ...
