摘要:
An I. V. stand is provided for (1) use by itself; (2) releasable use with a wheelchair providing for movement of its supporting wheels to provide only swiveling wheels; and (3) use with a gurney providing an adjustable arm attachment. The I. V. pole has an indicator for showing the position of a snubber, or attachment, mechanism used to contact the wheelchair. The I. V. stand has two castered forward wheels and two non-pivoted rear wheels with a castered fifth wheel located between the rear wheels for lifting the rear wheels off a floor when all castered wheels are desired on the I. V. stand.
