An internal grooved tube according to the present invention comprises a large number of fine spiral grooves on the inside surface in parallel arrangement, wherein the grooves are formed to assure that the ratio of a groove width in the tube axial direction to a groove height is in the range of 1 to 2. The RRM function uses data stored in a common database, including cell data and wireless transmitreceive unit data. The key is nested between the container and the platform wherein the slit opening of the key is sleeved over protrusions extending from the platform. The physician input may be received by the secondary device over a network.
