ABSTRACT:
An assembly for collecting blood or other body fluids is provided. The assembly includes an elongate tube having an open end and a closed end. The open end includes threads. An internally threaded plastic cap is mounted to the open end of the tube. The cap includes an axial passage and a resealable member aligned with the axial passage. A gas-impermeable member is bonded to the resealable member and the open end of the tube. Both the resealable member and gas-impermeable member are pierceable by a needle. The cap is removable with the resealable member and the gas-impermeable member as a unit due to the fact that the bond between the gas-impermeable member and the tube is weaker than that between the gas-impermeable member and the resealable member. The cap includes a deflectable portion near its top end to engage the walls of a tube holder, and to function as a shock absorber if the tube is dropped.
