ABSTRACT:
An I.V. apparatus including a stand, a bag hangably supported at an upper end thereof from the stand and adapted to contain an I.V. solution, a delivery tube for intravenous delivery of the I.V. solution to a patient by a catheter, a drip chamber extending downwardly at an upper end thereof from a lower end of the I.V. bag and connected at a lower end thereof with the delivery tube, a metering device positioned at the lower end of the I.V. bag and operative to deliver I.V. solution in drip fashion from the I.V. bag to the drip chamber, and an illumination device to insure that the desired drippage flow is taking place. The illumination device comprises a lamp assembly including a housing, batteries positioned within the housing, a light source positioned in the housing and powered by the batteries, a switch controlling the delivery of power from the batteries to the light source, and a clamp for releasably attaching the lamp to the upper end of the drip chamber. With the clamp releasably attached to the upper end of the drip chamber, a rod extending downwardly from the clamp positions the lamp housing in freestanding relation to the drip chamber with the light source positioned proximate to but spaced from the drip chamber so that the light source is operative to illuminate the drip chamber and thereby verify the presence of a drippage flow.
