PROBLEM TO BE SOLVED: To provide a height adjustment device of a drip infusion suspension device, capable of easily adjusting height and preventing an upper rod from lowering carelessly.SOLUTION: A lower housing 11 of a height adjustment device is fixed to a lower rod 1 of a drip infusion stand. An upper housing 21 is fixed to the lower housing 11. The lower housing 11 and the upper housing 21 are provided with a hole in each of the centers thereof. The upper rod 2 is inserted in the hole, and further upper rod 2 is inserted in the lower rod 1. A coil spring is stored in each of the lower housing 11 and the upper housing 21, and when the housings are moved to come close to each other by pinching a first lever 12 and a second lever 22, the inside diameters of the coil springs are enlarged, so that the upper rod 2 can be elevated. When the first lever 12 and the second lever 22 are set free, the coil springs are returned to their initial shapes by elastic force to reduce the inside diameter, and the upper rod 2 is fastened and fixed. |
