JP2000342557A - Blood specimen collection tube for blood specimen collection and blood specimen collection appliance kit for medical use consisting of appliance relating to preservation and transportation - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate the need for the labor to transfer information on the name or the like stated on the flank of a blood specimen collection appliance and to enable the use of the information on bar codes attached to the blood specimen collection appliance as it is. SOLUTION: This blood specimen collection tube is constituted by mounting a test tube 3 for subdivision at the outer side of the blood specimen collection tube 2 and forming the blood specimen collection tube 2 and the test tube 3 for subdivision as a pair of the devices. External threads are installed to the outer side of the aperture of the blood specimen collection tube 2 and internal threads are installed to the inner side of the aperture of the test tube 3 for subdivision. A coagulation accelerator, anticoagulant preparation or gelatinous blood separating material, or the like, are added into the blood specimen collection tube 2 and the blood specimen collection tube is well-stoppered with a rubber plug 1 after pressure reduction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION In the field of studying or examining blood, a blood collection tube for storing collected blood and a collected blood or plasma or serum separated from blood (hereinafter abbreviated as plasma) are sealed and stored. And transport equipment.

[0002]

2. Description of the Related Art Conventionally, when storing or transporting plasma obtained from blood, it is necessary to separate blood collected in a blood collection tube by a centrifugal separator and transfer the obtained plasma to a separately prepared test tube. Was.

[0003]

This has the following disadvantages. I. When separating plasma, it was necessary to transfer the name and the like described on the blood collection tube to a separately prepared test tube. B. Plasma of blood collection tube with a label such as a barcode,
If the test tube is transferred to a separately prepared test tube, information such as the patient's name, affiliation, and barcode attached to the blood collection tube cannot be used.

[0004]

Means for Solving the Problems Outside the blood collection tube (2),
Set up a test tube (3) for separation and storage. The connection shall be screw type. After reducing the pressure inside the blood collection tube (2), the blood collection tube (2) is sealed with a rubber stopper (1). The present invention is a blood collection device set relating to the blood collection tube for blood collection and storage and transportation configured as described above.

[0005]

Embodiments of the present invention will be described below. (B) A blood collection tube (2) having an external thread (11) provided outside the opening of the blood collection tube, and a female screw (12) inside the opening of the test tube.
The test tube (3) subjected to is inserted and mounted while rotating the test tube (3) from the lower side of the blood collection tube (2) upward. (B) The inner diameter of the test tube (3) is larger than the outer diameter of the blood collection tube (2) and there is a gap of 2 mm or less between the blood collection tube (2) and the air is filled with approximately 1 atm of air. I have. (C) After adding a coagulation accelerator, an anticoagulant preparation, a gel-like blood separating material, and the like to the inside of the blood collection tube (2), the pressure inside the blood collection tube (2) is reduced, and the opening of the blood collection tube (2) is closed with a rubber stopper (1). Seal tightly. The present invention has the above configuration. When using the present invention, the collected blood is inserted into the test tube by removing the rubber stopper of the blood collection device of the present invention or piercing the rubber stopper using an injection needle or the like. Next, after the blood is mixed with a coagulation accelerator, an anticoagulant, or the like in the blood collection tube, the blood is separated into blood cells and plasma by a centrifugal separator. Further, the screw portion of the test tube (3) is rotated to separate the blood collection tube (2) from the test tube (3), and the plasma above the blood collection tube (2) is transferred to the test tube (3) using a pipette or the like. The opening of the test tube (3) is sealed with parafilm or a separately prepared lid to prevent the test tube (3) from leaking out of the container.

[0006] The constituent materials of the blood collection tube and test tube of the present invention are not limited, but are preferably made of polyethylene tetarate.

The blood to be inserted into the blood collection tube is not limited to blood, but body fluids such as urine, bone marrow fluid, and ascites can also be used.

[0008]

According to the present invention, the trouble of transferring information such as a name written on the side of a blood sampling device to a test tube can be solved. In addition, the information of the barcode attached to the blood collection instrument can be used as it is, and can be used for a barcode reading device of an analyzer for testing blood.
