などの必要がある。2. Description of the Related Art At present, the blood collection of a human body is usually performed by a vacuum blood collection tube. The inside of this vacuum blood collection tube is kept vacuum by a robust rubber stopper, and blood is drawn from the human body into the vacuum blood collection tube by using an instrument having injection needles at both ends. For blood testing, it is essential to dispense blood from the blood collection tube to the outside, and it is necessary to stir or centrifuge the blood in the blood collection tube for the purpose of the test.

あるが、この作業も非常に面倒である。Conventionally, for these operations, a blood test is performed by manually removing the rubber stopper, but the rubber is fitted tightly to maintain the vacuum state, and the stoppers of many vacuum blood collection tubes are pulled out. On the other hand, while it is a difficult task, you must be very careful not to spill blood when opening the cap, and if the blood inside jumps, the inspector touches the blood and may cause infectious diseases such as hepatitis and AIDS. There is also a risk of getting infected. For this reason, although an automatic capping machine is being used, even if it does not hinder the dispensing of blood because it is capped, stirring and centrifugation are difficult to perform in the capped state, and the processing speed is significantly slowed down. If it is to be done smoothly, it is necessary to plug it again, but this work is not only time-consuming but also complicated.
For this reason, it has been proposed to puncture the needle for suction, but a negative pressure is generated inside, and a large amount of suction or injection is impossible. To solve this, it is necessary to open an air hole, but this work is also very troublesome.

内に連通孔が確保される。As described above, in the present invention, it is not necessary to remove the stopper because the penetrating tip is press-fitted by the pressing means to establish a communication state with the outside, and blood is dispensed and other work is performed in that state. There is no scattering of liquid that can occur when opening the cap, and since the penetrating tip is only inserted, there is no hindrance to work such as stirring and centrifugation, and a large amount of mechanical suction or injection can be performed. Is. Further, when the penetrating tip is fitted in the pressing means, since the hollow nozzle of the penetrating tip is closed by the needle portion of the pressing means, the material such as the rubber piece of the plug body enters the penetrating tip and the passage of the penetrating tip is inserted. There is no blocking, and a communication hole is secured in the hollow nozzle by pulling out the needle portion.

く押圧が行える。Further, when the penetrating tip is provided with the receiving portion, this portion is pushed by the pushing means, so that the pushing of the pushing means can be effectively absorbed. As a result, there is no problem even if the diameter is large, and accordingly, the inner diameter can be made larger than the diameter of the dispensing nozzle, so that the nozzle having the inner diameter larger than the diameter of the dispensing nozzle can be obtained. Therefore,
When the dispensing nozzle is inserted, there is room for ventilation on the outside, and it is not necessary to pierce the needle to separately provide a ventilation hole. Further, when the penetrating tip funnel-shaped receiving portion is formed, pressing can be performed without trouble even when the center of the pressing means or the penetrating tip is displaced.
