In addition, Korean Utility Model Registration No. 20-0291401 discloses a blood collecting container for both disposable syringes, which does not need to be transferred to another container and which can preserve the collected blood in a circular shape.

The inside of the blood vessel is filled with a filler selectively. For example, a gel and a liquid reagent for forming a separation wall between blood cells and plasma through centrifugation can be mentioned.

When a blood vessel is manufactured, a series of processes are sequentially performed. A lower portion of a container (hereinafter, referred to as a blood collecting tube) is inserted into a cartridge having an insertion hole formed in row and column directions to align an opened upper portion of the container A gel dispensing step of injecting a gel for separating serum and blood cells into the blood collection tube; a step of dispensing a liquid reagent into the blood collection tube with a large droplet or a small droplet so as to be impregnated on the inner wall surface; A drying step of performing drying by forced convection of dry hot air to the interior of the blood collecting tube, and a vessel closing procedure.

When it is necessary to maintain a vacuum state lower than the atmospheric pressure inside the blood collection tube, there is a process of decompressing the blood collection tube to a vacuum state in the blood vessel sealing process.

Here, the vacuum state means a space in which no substance is present at all, but usually the inside of the blood collection tube has a low pressure of about 40 to 140 torr.

In general, the blood collection tubes are conveyed to the inside of the chamber in such a manner that the lower portion of the blood collection tube is inserted into the cartridge provided with the insertion holes arranged in the row and column directions and the opening of the blood collection tube is arranged to face upward, Is fixed to a plate having the same arrangement batten, or is transferred into the chamber so as to be in line with the blood collection tube above the upper portion where the opening of the blood collection tube is formed.

The blood collection tube and the cap are separated from each other by a predetermined distance in the chamber, and the chamber is sealed in a state in which the chamber is vertically aligned, and then the inside of the chamber is decompressed to a vacuum state.

As the inside of the chamber is evacuated to a vacuum, the inside of the blood collection tube is also evacuated.

In the state where the inside of the chamber is completely vacuumed and the cap is pressurized downward with the blood collection tube, when the blood collection tube is sealed, the blood collection tube sealing process is completed.

However, in the conventional method, a method of positioning the cap at a predetermined distance above the blood collection tube is difficult and difficult to manage, which is difficult in forming a vacuum.

Also, when the cap is detached after the cap is detached, the cap is separated from the blood collection tube by the pressure of the air that enters the blood collection tube while separating the cap.

Therefore, it is required to provide a method of easily managing the blood vessels and the cap to be transferred to the inside of the chamber, allowing the air inside the blood vessel to be easily moved to the outside, and not being separated without external force when the cap and the blood vessel are recombined.
