CLOSURE STRUCTURE FOR VACUUM SPECIMEN COLLECTION CONTAINER, VACUUM SPECIMEN COLLECTION CONTAINER, VACUUM SPECIMEN COLLECTION SYSTEM, HOLDER FOR VACUUM SPECIMEN COLLECTION SYSTEM AND THERMOPLASTIC ELASTOMER COMPOSITION FOR FORMING CLOSURE STRUCTURE |
摘要 |
A closure structure is provided for a vacuum specimen collection container which can maintain a vacuum pressure within the specimen collection tube and which includes a needle cannula penetrating portion having needle hole sealability. The closure structure can be detachably fitted in an open end of a specimen collection container in an airtight manner to maintain a vacuum condition with the specimen collection container. The closure structure includes a grip section, a rubber elastic needle cannula penetrating portion disposed to fill up a through-hole in a grip section and a rubber elastic fitting portion configured to follow an interior surface profile of an open end of a specimen collection container, thereby to fit therein in an airtight fashion. The grip section has a higher rigidity relative to the needle cannula penetrating portion and the fitting portion. A tubular side wall of a grip section has on its inner side at least one raised portion or recessed portion to prevent kickback.
