That is, in Examples 1 to 3 shown in Table 1, 20 ml, 40 ml and 60 ml of the scale 9b formed on the outer surface of the decompression degree adjusting cylinder 9, respectively.
The rod 11 was pulled so that the decompression degree display marker 13 was positioned at the value of, and the blood collection tube 2 was stoppered in that state to obtain a vacuum blood collection tube.

Thereafter, the degree of pressure reduction of the vacuum blood collection tubes obtained in Examples 1 to 3 was measured by sucking water. The amount of water sucked thus measured is shown in Table 1 below as an actual measurement value. Further, in Table 1 below, the theoretical values calculated based on the volume change in the pressure reduction degree adjusting cylinder 9 are shown in parentheses.

[0025]

[Table 1]

As is clear from Table 1, there is a difference of about 0.2 ml between the measured average value and the theoretical value. In consideration of this error, the display scale 9 of the decompression adjustment cylinder 9 is shown.
It can be seen that the desired degree of pressure reduction can be reliably achieved by adjusting b.

Therefore, it can be seen that the vacuum blood collection tube manufacturing apparatus suitable for being used in the limited space in the hospital can be provided.

Next, an embodiment using the vacuum blood collection tube manufacturing apparatus 21 will be described. A 4 cc blood collection tube 2 was placed in the blood collection tube storage chamber 23, a rubber stopper 14 was placed on it, and the degree of pressure reduction by the compressor 30 was adjusted as shown in Table 2 below to manufacture a vacuum blood collection tube. In each of Examples 1 to 3, a vacuum blood collection tube was manufactured using five blood collection tubes 2.

The degree of decompression of the vacuum blood collection tube obtained as described above was measured by sucking water. The measured degree of reduced pressure (water absorption amount) is shown in Table 2 below. Table 2 below shows the average value of the reduced pressure levels of the five vacuum blood collection tubes as the measured average value together with the theoretical value obtained from the set value of the reduced pressure levels.

[0035]

[Table 2]

As is apparent from Table 2, there is almost no difference between the measured average value and the theoretical value, and therefore, by using the vacuum blood collection tube manufacturing apparatus 21, the vacuum blood collection tube adjusted to a desired degree of reduced pressure is obtained. It can be seen that is surely obtained.
