Cushioning device of support column on infusion stand

Abstract

Provided is a damping device for a support post in an irrigator stand, which prevents the support post from rapidly falling with a simpler configuration. As the damping device 13, a plug member 7 closing the lower end side inside a base part column 3a and a damping valve 14 of a cap shape to be closely slid on the inner wall of the base part column 3a facing the plug member 7 on the lower end part side of the support column 3b are provided. The plug member 7 is provided with an air flow path 15 communicating with a space inside the base part column 3a and the outside of a bottom surface along the outer periphery of the axial direction. In the meantime, for a valve part 14b in the damping valve 14, the outer peripheral part is spread in a tapered shape, a space part G is formed between the damping valve and a grounding part 14c on the inner side of the valve part 14b, and a cylindrical hollow part Rg is formed at the grounding part 14c. A surface area is enlarged by the cylindrical hollow part Rg and the space part G on the inner side of the valve part 14b, and an air damping function is improved.

Description

technical field [0001] The present invention relates to a cushioning device for a support column on an infusion stand that prevents the support column from falling down suddenly due to gravity on a transfusion stand that can be combined up and down with a support column provided with a sling for hanging drip bottles. Background technique [0002] For example, it is an infusion stand that can be freely moved, such as hanging drip bottles as hospital equipment. On the infusion stand, the pillar part for hanging the drip bottle can be telescopically adjusted, and can be fixed by an appropriate fastening and holding device, so that the drip bottle can be hung at a desired height. [0003] Therefore, if the fastening of the fastening and holding device is loosened, or when the holding height of the drip bottle is adjusted, the fastening and holding device is suddenly loosened. Due to the weight of the drip bottle, the upper side of the support part ...

AI Technical Summary

Problems solved by technology

[0009] However, in the above-mentioned infusion stand 1, as mentioned above, the structure of the valve body 9 also includes the receiving member 8 having the holding shaft 8a, the flange portion 8b, etc., which hold the valve body 9 in a loose fitting state and are in close contact. 1. The structure used to play the role of air cushioning, especially the structure of the valve body 9 is relatively complicated. In order to obtain the desired dimensional accuracy, it must be processed, and the number of parts is also slightly larger, so the manufacturing cost is difficult to suppress
