Detailed description of the invention

Below, will by reference to the accompanying drawings the holding device for infusing of the present invention be described in detail.

It should be noted that, description of the present invention and accompanying drawing are only for illustration of the operation principle of the holding device for infusing of the present invention, and the holding device for infusing of the present invention is not limited to the content limited of word and accompanying drawing.

As the most preferred embodiment that Fig. 1-8 is the holding device for infusing of the present invention.

Holding device for infusing of the present invention comprises two parts, Part I 10 and Part II 20.Part I 10 combines with Part II 20 is separable, forms cylinder.Here, Part I 10 can be by magnetic force with the combination of Part II 20, and being such as made up of ferromagnetic material, also can be by arranging pivot between Part I 10 and Part II 20.This cylinder is formed with vacancy portion in its both sides, inserts for the bottleneck to infusion bottle/transfusion bag supply gas pin or other syringe needles.

The top of cylinder for block the bottleneck of infusion bottle/transfusion bag convex edge above.Particularly, blocked above the convex edge of the bottleneck of infusion bottle/transfusion bag by resilient clip 41,42.Resilient clip 41,42 is arranged on respectively by spring 43,44 in the groove 11 on Part I 10 and in the groove 12 of Part II 20.Thus, resilient clip 41,42 can moving radially along cylinder, to be applicable to the bottleneck of the infusion bottle/transfusion bag of different thicknesses.

The bottom of cylinder for block the syringe needle of transfusion device convex edge below.Particularly, blocked below the convex edge of the syringe needle of transfusion device by resilient clip 51,52.Resilient clip 51,52 is arranged on respectively by spring 53,54 in the guide groove 21 on Part I 10 and in the groove 22 of Part II 20.Thus, resilient clip 51,52 can moving radially along cylinder, to be applicable to the syringe needle of the transfusion device of different thicknesses.

Guide groove 21,22 not only can provide the activity space of cylinder radial direction for resilient clip 51,52, can also for resilient clip 51,52 provide Cylindorical rod to activity space, now, guide groove 21,22 is formed as microscler in the axial direction.

Guide groove 21,22 can form open opening on the outer peripheral face of cylinder, and like this, the outside of cylinder can be extended in its end by resilient clip 51,52.Now, the outer peripheral face of cylinder can be formed the screw thread (not shown) around outer peripheral face, like this, nut 30 just can move up and down around the screw thread rotation on the outer peripheral face of cylinder.The part that resilient clip 51,52 extends cylinder outer peripheral face is subject to the support of nut 30, can move up thus.Resilient clip 51,52 can also be supported with spring (not shown) above it, and spring is contained in guide groove 21,22, moves down for resilient clip 51,52 power of providing support.

Resilient clip 51,52 is preferably formed as " ten " font.Correspondingly, the cross sectional shape of guide groove 21,22 is also " ten " font.

Because Part I 10 and Part II 20 are formed with screw thread respectively, so, it is very accurate that Part I 10 and the position relationship of Part II 20 need, nut 30 may be caused after dislocation cannot to be attached on cylinder outer peripheral face, therefore, on Part I 10 with Part II 20 faying face, be respectively arranged with the projection for locating and depression (not shown), projections mesh on Part I 10 is in the depression of Part II 20, and the projections mesh of Part II 20 is in the depression of Part I 10.

The above-mentioned most preferred embodiment for the holding device for infusing of the present invention.It can regulate in the thickness of the syringe needle of the bottleneck size of infusion bottle, transfusion device, distance three between infusion bottle and infusion needle, is applicable to various infusion bottle, transfusion bag and transfusion device.

For the situation not needing all to carry out regulating in three, for the holding device not needing to adapt to of specific infusion bottle and transfusion device, or the holding device that only need regulate one of them or two aspects, now, only needs above-mentioned most preferred embodiment to adjust.

Such as, to the holding device of the syringe needle of specific infusion bottle and transfusion device, then without the need to resilient clip, only the top of cylinder, bottom need be stuck on infusion bottle and syringe needle for transfusion device.

When only needing to adapt to the size of infusion bottle, only need the resilient clip that top is set.

When only needing to adapt to the size of the syringe needle of transfusion device, the resilient clip of bottom only need be set.

Here, repeat no longer one by one.
