Abstract
A motorized IV pole system for controlling the height of an IV container to thereby control the infusion pressure in an IV tube includes a telescoping IV pole system. In one embodiment, comprising three concentric support members, the outer support member is fixed, the middle support member is reciprocable with respect to the outer support member and is driven by a rack gear attached thereto. An inner support member is reciprocatable in the interior of the middle support member and is driven by a cable attached to the outer support member passing over a pulley attached to the middle support member. The rack on the middle support member may be driven by a shaft to which is attached a hand crank and an AC motor. The AC motor may be driven by a programmable control system which includes an optical encoder to permit display of the height of the IV container. Also, preselected heights and various speeds of height adjustment may be utilized. Another embodiment employs a tubular support member carrying a nut driven by a concentric threaded shaft. A friction-adjustable bearing for maintaining the position of the shaft permits manual height adjustment.
