Abstract
The utility model relates to a combined cap with a rubber plug, which can prevent liquid from leaking during a transfusion. The combined cap comprises an inner cap (2) and an outer cap (3). A suspension link (31) is arranged on the outer cap (3). The rubber plug (1) and a sealing film (21) are orderly arranged between the outer cap (3) and the inner cap (2), wherein a dispensing mouth (12) which does not penetrate the rubber plug and a transfusion mouth (11) are arranged on the diametric direction of the rubber plug (1), and the diameter of the transfusion mouth (11) is more than that of the dispensing mouth (12). The combined cap is characterized in that the axial sections of the dispensing mouth (12) and the transfusion mouth (11) are symmetrical corresponding to a central plane where center lines (A-A') of the upper surface and the lower surface of the rubber plug (1) are positioned, and the thickness of the thinnest part of the rubber plug at the dispensing mouth (12) is more than that of the thinnest part of the rubber plug at the transfusion mouth (11).
Description
Technical field
This utility model belongs to medical package material field, particularly the transfusion plastics package architecture advances of composite cover.
Background technology
The wrapping draw-ring type composite cover of existing transfusion flexible bag (bottle) as shown in Figure 9, used plug is shown in Figure 10,11,12.Medicinal liquid can not worn out by needle tubing because of inner cap 2 and ooze out outside the transfusion bag (bottle) when the plug significant feature was injection; After making up a prescription simultaneously, plug can seal the pollution that is not subjected to outside air with the medicinal liquid in the assurance container because of the hole of being pierced through by syringe needle of making up a prescription; Guarantee also simultaneously that the medicinal liquid in the container can be from mouthful 12 outflows of making up a prescription when transfusion.The bottle plug puncture unit syringe needle external diameter of used disposable transfusion device is about 6mm during transfusion, and the syringe needle external diameter of the used syringe that makes up a prescription generally is not more than 1.2mm.As shown in figure 10, the mouth 12 that makes up a prescription is combined with infusion port 11, whole relatively plug, piercing through infusion port is the same with make up a prescription mouthful suffered resistance and distortion, there is following point so in use: after making up a prescription, the thickness (h in the diagram) of the plug thinnest part at place is less than normal owing to make up a prescription mouthful, and therefore medicinal liquid can ooze out from make up a prescription mouthful by the hole that syringe needle pierced through of syringe when transfusion; During transfusion, because the thickness (h ' in the diagram) of the plug thinnest part at infusion port place is bigger than normal, it is big to join plug perforator syringe needle resistance when piercing through plug on the transfusion device, the distortion of plug is also big simultaneously, cause plug squeeze broken composite cover in the diaphragm seal that covers enter in the packing container, plug loses the effect that exterior and interior cover sealing is cut off like this, thereby medicinal liquid directly oozes out from composite cover when causing infusing.
The utility model content
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, provides a kind of and can prevent that when transfusion medicinal liquid from piercing through the medicinal liquid packaging composite cover that mouth oozes out from plug.
The composite cover that to prevent the plug of leakage when infusing that has of the present utility model, comprise inner cap and enclosing cover, outside this, cover to have between a draw ring, this enclosing cover and this inner cap and dispose plug and diaphragm seal successively, wherein, on the diameter of this plug, be arranged with make up a prescription mouth and the infusion port that do not penetrate plug, the diameter of this infusion port is greater than the diameter of this mouth that makes up a prescription, it is characterized in that the shaft section of this make up a prescription mouth and this infusion port is with respect to centrage symmetry and this thickness of mouthful thickness of place's plug thinnest part greater than this infusion port place plug thinnest part that makes up a prescription on two surfaces up and down of this plug.
Have a composite cover that transfusion the time can be prevented the plug of leakage according to of the present utility model, it is characterized in that, the 1.5-3 of the thickness that this mouthful thickness of place's plug thinnest part that makes up a prescription is this infusion port place plug thinnest part doubly, more preferably 1.5-2 is doubly.
According to the composite cover that to prevent the plug of leakage when infusing that has of the present utility model, it is characterized in that the shaft section of this infusion port is trapezoidal.
According to the composite cover that to prevent the plug of leakage when infusing that has of the present utility model, it is characterized in that the shaft section of this infusion port is a circular part.
According to the composite cover that to prevent the plug of leakage when infusing that has of the present utility model, it is characterized in that the shaft section of this infusion port is an oval-shaped part.
Compared with prior art, the beneficial effects of the utility model are: this utility model is only made the problem that less modification can solve the leakage of original existence on the structure of plug in original.
