Cushioning device of support column on infusion stand

Abstract

The object of the present invention is to provide a cushioning device for a support column on a transfusion stand that prevents the support column from falling suddenly with a simpler structure. As a buffer device (13), it includes: a plug member (7) that seals the lower end side of the base pillar (3a), and a plug member (7) on the lower end side of the support pillar (3b). 7) Oppositely, the cap-shaped buffer valve body (14) is in close contact with the inner wall of the base support (3a) and slides. An air passage (15) connecting the inner space of the base support (3a) with the outer side of the bottom surface is provided on the plug member (7) along the outer periphery in the axial direction. On the other hand, the valve portion (14b) of the buffer valve body (14) has a tapered outer peripheral portion to form a space (G) with the ground portion (14c) inside the valve portion (14b), so The ground portion (14c) is formed with a cylindrical hollow portion (Rg). The surface area is enlarged by using the cylindrical hollow portion (Rg) and the space portion (G) inside the valve portion (14b) to enhance the air cushioning function.

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 may drop sharply, which may be ...

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
