PURPOSE: To prevent reuse of a liquid sampling device for one-time use, by equipping the device with a head on which a stopper of a sampling tube slides and a main body to guide the sampling tube and forming a breaking part on the point to join the head part and the main body. CONSTITUTION: A main body 14 to which a tube 10 is attached has a conical shape, and has an outer collar 32 at the open end, and has two retaining studs 36 at the other end 34 to be in contact with a head 12. The cylindrical head 12 consists of a base 16 and an outer case 18 formed with four slots. The head 12 and the main body 14 are connected by the joining portion made by thin material. The head 12 is separated from the main body by breaking the breaking point formed at the reduced region of the diameter. The head 12 is discarded with the needle 51, and the sampling tube 38 can be taken out from the main body 14 by moving it in the same direction as at the time of installation. |
