Embodiment

Below, the holding meanss for being used to infuse of the present invention will be described in detail with reference to accompanying drawing.

It should be noted that the specification and accompanying drawing of the present invention are merely to illustrate the holding meanss for being used to infuse of the present invention Operation principle, the of the invention holding meanss for being used to infuse are not limited to the content limited of word and accompanying drawing.

Such as the most preferred embodiment that Fig. 1-8 is the holding meanss for being used to infuse of the invention.

The holding meanss for being used to infuse of the present invention include two parts, Part I 10 and Part II 20.Part I 10 with Part II 20 is separable is combined together, form cylinder.Here, the combination of Part I 10 and Part II 20 can To be to be made or by magnetic force, such as by ferromagnetic material by being set between Part I 10 and Part II 20 Put pivot.The cylinder is formed in its both sides has vacant position portion, for the insertion of the bottleneck of infusion bottle/infusion bag supply gas pin or other Syringe needle.

The top of cylinder is used to block above the convex edge of the bottleneck of infusion bottle/infusion bag.Specifically, resilient clip is passed through 41st, above the convex edge of 42 bottlenecks for blocking infusion bottle/infusion bag.Resilient clip 41,42 is arranged on the by spring 43,44 respectively In groove 11 in a part 10 and in the groove 12 of Part II 20.Thus, resilient clip 41,42 can be along the footpath of cylinder To movement, with the bottleneck of infusion bottle/infusion bag suitable for different thicknesses.
