ABSTRACT:
A fluid transfer device has a resilient reservoir connected to a rigid hollow punch made of synthetic resin. The punch is precisely sized to enable manual penetration of rubber stoppers found on standard evacuated tubes which are commonly used for blood sampling. The diameter of the punch also allows for transfer of the fluid from the sample tube to the device in a reasonable amount of time. A method of transferring blood or blood products from the sample tube to testing apparatus involves using the device to penetrate a rubber cap on an evacuated tube and then transfer the blood to the device. The blood can then be transferred to a testing apparatus without exposure to the atmosphere.
