Description

Be used for the composite cover of transfusion package and have the infusion vessel of this composite cover

Technical field

This utility model relates to the medical packaging field, more specifically, relates to a kind of infusion vessel that is used for the composite cover of transfusion package and has this composite cover.

Background technology

The composite cover of prior art and plastics package with this composite cover are as shown in Figure 1, composite cover is made up of enclosing cover 41, plug 42 and inner cap 43, at first enclosing cover sealing 411 is removed during use, expose plug 42 so that use for the syringe puncture, in use, the puncture needle of transfusion device is held tightly to guarantee that transfusion device can not break away from infusion vessel when infusing by plug 42.

The inventor finds that there are the following problems at least in the prior art: the plug diameter in the composite cover is too big, and plug material price costliness, plug 42 costs of the prior art account for whole composite cover 4 costs about half, so reduce the cost that plug 42 diameters can reduce plug 42.Because the particularity of infusion products, enclosing cover sealing 411 before use can not be damaged, draw ring can not be broken in use, but the part at enclosing cover 41 centers must be pulled open with plug 42 in exposing, satisfying above-mentioned requirements makes very high to the material requirements of enclosing cover 41, promptly should satisfy the welding fusing point the same, require the enclosing cover 41 back draw rings that are shaped that stronger tenacious and persistent will is arranged simultaneously again with inner cap 43.The material price that satisfies this requirement is three times of inner cap 43 material prices, so reduce the cost that the materials of enclosing cover then can reduce composite cover.Based on this 2 point, make that composite cover 4 costs are very high as shown in Figure 1.
