The above-mentioned rubber plug used in the combined cover generally includes a rubber plug body, and the lower plane of the rubber plug has an annular slot for the upper convex ring of the plastic sub-cover to be clamped. The disadvantages of this rubber plug are:
[0005] 3. If the existing rubber stopper is in contact with the medicine for a long time, it will pollute the medicine. Therefore, in order to avoid the contact between the butyl rubber plug and the medicine, the upper part of the plastic sub-cover of the existing combined cover is provided with a plastic cover plate, but the inclined needle penetrates It is easy to produce plastic dust and bring it into the infusion bottle, which will have an adverse effect on the patient, because the needle needs to pierce the plastic cover when the needle penetrates the colloid, resulting in increased resistance in the needle and instantaneous puncture when the colloid is bound by the plastic cover. The greater the force, the more chip falling, the relative chip falling increases, the colloid is damaged, and the part that lacks glue virtually forms a leak

Embodiment
[0021] Example: such as figure 1 As shown, a rubber stopper for infusion includes a rubber stopper body 1, a conical needling cavity 2 and three circular needling cavity 4 are arranged on the upper plane of the rubber stopper body 1, and the conical needling cavity 2 is located at the center of the rubber stopper body 1, and three circular needling pockets 4 are arranged at intervals on the outer periphery of the tapered needling pockets 2. The lower plane of the rubber stopper body 1 corresponds to the tapered needling pockets 2 and the circular A first groove 3 and a second groove 5 are respectively provided at the positions of the needle pricking recesses 4 . The setting of the above-mentioned conical needling cavity 2 and the first groove 3 not only avoids the occurrence of rubber needle dust and falling pieces when the resin needle enters the rubber stopper, so as to contaminate the medicine, but also prevents the rubber from cracking after the resin needle is punctured. ...

The invention discloses a transfusion rubber plug which comprises a rubber plug body, wherein at least one conical puncture concave hole is formed on the upper plane of the rubber plug body; and a first groove is formed on the lower plane of the rubber plug body at the position corresponding to the conical puncture concave hole. According to the transfusion rubber plug, the problems that rubber needle bits and falling scraps are generated when a transfusion needle enters the rubber plug and the pollution on medicaments is generated are avoided, the rubber rupture after puncture of the transfusion needle is prevented at the same time, the sealing property of the rubber plug is ensured, and the liquid leakage is avoided.
Description
technical field [0001] The invention relates to a rubber stopper for transfusion. Background technique [0002] At present, ordinary infusion plastic bottles are no more than soft bags and plastic bottles. The bottle caps are generally composed of plastic female caps, rubber plugs and plastic sub-caps. When assembling, first put the rubber plug into the plastic female cap. Inside the cover, press the plastic sub-cover into the plastic female cover from bottom to top. The inner lower edge of the plastic female cover is provided with a circle of grooves, and the outer lower edge of the plastic sub-cover is provided with a ring of flanges, and the flanges are embedded in the grooves. In the groove, the plastic sub-cap can be fixed in the plastic mother cap, and the rubber plug is pressed tightly. After the sub-mother cap and the rubber plug are assembled, they are cleaned. The mouth of the bottle is fused, and the packaging of the soft bag or plastic bottle can be completed by...
