Infusion stand

Abstract

The invention relates to an infusion stand, comprising a base, a fixing pipe and a lifting rod, and further comprising a sliding seat, two sealing rings and two positioning rings; the sliding seat isof a cylindrical structure, is fixed at the lower end of the lifting rod, and is located in the fixing pipe in a way of being slidable up and down; the outer side wall of the sliding seat is providedwith two rings of sliding grooves up and down, the lower part of the upper sliding groove is provided with a groove, and the lower part of the lower sliding groove is provided with a straight hole; abuffer hole is formed in a position, near the bottom, of a side wall of the fixing pipe; the two sealing rings are respectively sleeve the outer circumference of the sliding groove in a way of being slidable up and down; the two positioning rings and the two sealing rings are arranged in one-to-one correspondence. The infusion stand has the beneficial effects that the condition that when the lifting rod is downward collected into the fixed tube and shortened, the lifting rod from falls to the lowest position to form a large impact, and a medicine bottle is shaken off or directly broken by shake can be avoided, and when the lifting rod is extended upward from the fixing pipe, air pressure in the fixing pipe can keep a balanced state to facilitate extending the lifting rod.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an infusion stand. Background technique [0002] In order to facilitate the hanging of medicine bottles and convenient storage when not in use, the existing infusion stand is made into a retractable structure composed of a fixed tube and a lifting rod. After the medicine bottle is hung on the top of the lifting rod, pull the lifting rod out of the fixed tube to extend it, and tighten the screw on the fixed tube to fix the position of the lifting rod for infusion; after the infusion, loosen the screw under the action of gravity The elevating rod is received in the fixed tube again to be shortened, and finally the medicine bottle is taken off. In the above method, when the infusion is completed and the lifting rod is put into the fixed tube, since the medicine bottle is suspended on the top of the lifting rod, under the action of the combined gravity of the medicine bottle and t...

AI Technical Summary

Problems solved by technology

In the above method, when the infusion is completed and the lifting rod is put into the fixed tube, since the medicine bottle is suspended on the top of the lifting rod, under the action of the combined gravity of the medicine bottle and the lifting rod, the medicine bottle will freely fall downward along with the lifting rod Accelerated movement, when the lifting rod falls to the lowest position, it has a greater speed, and it will stop after a greater impact, and the formed impact will be transmitted to the medicine bottle, causing it to vibrate and drop or directly shatter, resulting in an accident event
