- the material of the plug having a gas-barrier property and a needle-hole sealing property for hermetically sealing a container or a cylinder provided in a nested structure is, for example, butyl rubber; an aluminum sheet and isoprene. Composites of rubber, natural rubber, etc .; thermoplastic elastomers, etc. can be used as appropriate.
- the inner diameter of the opening of the outer container is made substantially equal to the inner diameter of the plug of the container or tube that is nested inside, so that the sample after collection Can be used as a plug to seal the opening of the outer container after the unnecessary inner container or tube is discarded after mixing with the pretreatment agent.
- the closing part of the outer container for hermetically closing the lower opening end of the cylinder provided in the nested structure is integrated with the outer container.
- the closing portion may be separately formed of butyl rubber, thermoplastic elastomer, or the like, and may be incorporated into the inner surface of the bottom of the outer container or the inner wall near the lower open end of the cylinder.
- the outer container may also be formed into a tubular container by fitting the closing member, which has also been formed beforehand, into a preliminarily formed cylindrical body.
- the sample pretreatment agent is used by being mixed with the sample.
- a conventionally known blood coagulation accelerator an anti-coagulant
- these can be appropriately stored as a solution, powder, or a lyophilized product, or can be stored on a wall surface, or supported by beads, a sheet, or a nonwoven fabric.
- the inside of the container or tube to be housed does not contain a drug that may flow back into the body at the time of specimen collection, but is not used for various therapeutic applications such as heparin salt. Drugs whose safety has been confirmed may be contained.
- the container provided in the nested structure, the container or the tube provided in the nested structure, etc. are manufactured by a known manufacturing method according to the material used for each.
- the above material is a thermoplastic resin
- injection Examples include a method of manufacturing by molding or blow molding.
- the first to fourth vacuum sample collection tubes of the present invention are manufactured by manufacturing a container externally mounted in a nested structure, a container or a tube internally mounted in a nested structure, and assembling them.
- the space accommodating the sample and the space accommodating the pretreatment agent at the time of vacuum sample collection are completely separated. It is expected that the danger of backflow will disappear, and that it will spur the spread of safer sample collection systems.
- the blood collection needle tube is not properly fixed in the blood vessel due to the blood vessel of the blood collection subject being thin, or the blood pressure drops during blood collection, and unexpectedly it takes a long time to complete the blood collection. If a trouble occurs, such as the necessity of a reaction, the reaction start time becomes ambiguous and the user does not use it.
- the storage space for the specimen and the storage space for the pretreatment agent are separated as in the present invention, the two can be mixed at once immediately before the actual test, thus improving the accuracy of the test. Extremely useful.
