WIPO Patent Application WO/1988/004154
Kind Code:
A1
Abstract:
A blood sampling tube is equipped with a bottomed cylinder whose one end is open and the other end is closed, and a sealing member bonded to the open portion of the tube to seal it. Another blood sampling tube of this invention is equipped with a bottomed cylinder whose one end is open and the other end is closed and a sealing member capable of being pierced by a hollow needle, bonded to the open portion of the tube and sealing the open portion, wherein the interior of the tube is evacuated suitably in accordance with a blood quantity. The sealing member consists of a gas-barrier member having high air-tightness in order to substantially keep the interior of the tube depressurized till blood sampling and a sealing material capable of closing the hole of the needle after the needle piercing the sealing member at the time of blood sampling has been removed. Therefore, when blood is sampled using a needle or the like means for inspection, it is not necessary to remove a plug member from the open portion of the tube for opening the tube and the blood sampling tube can be handled easily. Moreover, air-tightness can be secured from the production of the tube till its use, the hollow needle can be used easily for piercing and liquid-tightness can be secured after removing the hollow needle.
