Abstract
The utility model discloses a medical plastic compound sealing cover, which comprises a plastic cover body, and at least a rubber gasket and an aluminum foil, wherein the cover body is composed of a wall portion and a bottom portion. The utility model is characterized in that the bottom portion is provided with groove(s) extending toward the inner side of the sealing cover, the number of the groove is same as the that of the rubber gasket, the rubber gasket is tightly fitted in the groove, the aluminum foil is attached on the outer side of the bottom portion so as to cover the rubber gasket, and part of the aluminum foil is freely extended out from bottom portion. The medical plastic compound sealing cover has advantages of simple structure, low material consumption, low cost, easy operation, hygienic and reliable performance, as well as high suitability for transfusion in hospital.
Description
Technical field
This utility model relates to a kind of medical plastic compound seal lid, and it can be used on plastic infusion bottle or the plastic infusion bag.
Background technology
At present, the seal cover of common plastic infusion bottle or bag is made by aluminum or plastics usually, and wherein plastic closure is because processing is simple, operation, safe and reliable and more and more welcome easily.A kind of plastic closure commonly used has been shown among Fig. 3, it comprise outer cover 13, and the interior lid 14 that is welded together of outer cover, be clipped between lid and the outer cover disc rubber blanket 12, attached to the draw ring 11 in the outer cover outside.During use, utilize draw ring 11 to tear outer cover bottom, Medicated needle of syringe and infusion needle are stung rubber blanket 12 and interior lid 14 and stretch in plastic bottle or the bag.The effect of rubber blanket is the sealing when keeping dosing and transfusion.
The shortcoming of this common plastics seal cover is, use two plastic covers and the rubber blanket that size almost equates with the transverse section of inside and outside lid, so the consumption of plastics and rubber is all more, and material cost is higher.Simultaneously, need the inside and outside lid of injection moulding respectively, so processing cost is comparatively expensive.In addition, the operation that utilizes draw ring to tear outer cover is comparatively required great effort, and the fracture of draw ring meeting causes unnecessary trouble sometimes.
Therefore, if can provide a kind of simple in structure, be easy to make, easy-to-use medical plastic seal cover, will be popular.
Summary of the invention
The purpose of this utility model provides a kind of easy easy-to-use medical plastic seal cover, to solve the problems referred to above that exist in the conventional art.
According to this utility model, a kind of medical plastic compound seal lid is provided, it comprises a plastic cover, at least one rubber blanket and an aluminium foil, lid has wall portion and bottom, it is characterized in that: described bottom has the groove that equates with rubber blanket quantity that stretches out towards the seal cover inboard, and close fit rubber blanket in the groove, and described aluminium foil is attached to the outside of described bottom, to cover described rubber blanket, the part of aluminium foil is freely stretched out from described bottom.
Preferably, the quantity of described rubber blanket is two.The shape of groove and rubber blanket with cylindrical be good, but also can be other shape.The cross dimension of rubber blanket is more bigger than described rubber blanket, highly is equal to or less than rubber blanket.
Preferably, described aluminium foil heat-sealing is on described bottom.Aluminium foil is preferably strip, but also can be other shape.
Preferably, the opening of described lid wall portion has radial flange, and described flange is combined on the mouth flange of plastic infusion bottle or plastic infusion bag.Preferably when described lid injection moulding, the flange welding of lid wall portion on the mouth flange of plastic bottle or bag, but also can be realized above-mentioned combination by modes such as heating after the lid molding.
Medical plastic compound seal lid of the present utility model is simple in structure, and materials are few, so cost is low.In addition, it is easy and simple to handle, and health is reliable, is very suitable for transfusion use in the hospital.
Other purposes of the present utility model and advantage can draw from the detailed description of being done with reference to the accompanying drawings.
Description of drawings
Fig. 1 is a kind of schematic cross sectional views according to medical plastic compound seal of the present utility model lid and the plastic bottle that adheres to thereof;
Fig. 2 is the vertical view of medical plastic compound seal lid;
Fig. 3 is the schematic cross sectional views of a kind of traditional infusion with the seal cover of plastic bottle or bag.
The specific embodiment
Describe a kind of with reference to the accompanying drawings according to medical plastic compound seal lid of the present utility model.
As illustrated in fig. 1 and 2, be such seal cover according to medical plastic compound seal lid of the present utility model, it comprises a plastic cover 2, at least one rubber blanket 4 and an aluminium foil 3.The lid 2 of integral injection molding has cylindrical wall and is connected the bottom of wall portion one end.The other end opens wide and has a flange that radially outward stretches out.Described flange surface faces toward the bottleneck flange of plastic bottle 1, and is welded together with it, thereby lid hermetic is connected on the bottle.Described welding can realize when lid injection moulding, also can realize by modes such as heating after the lid molding.
The bottom of the lid 2 of seal cover has the groove that stretches out towards the seal cover inboard, and close fit rubber blanket 4 in the groove.Described groove and rubber blanket can have Any shape, for example can be combinations of cylinder, cylindroid, cuboid, square, above-mentioned shape or the like, but consider processing characteristics, are best with cylindrical.The quantity of groove (rubber blanket) is at least one, so that can penetrate at least one syringe needle.In illustrated embodiment, the quantity of groove (rubber blanket) is two.The shape of rubber blanket 4 is identical with groove, but highly is less than or equal to the degree of depth of groove.For rubber blanket firmly is installed in the groove, the cross dimension of rubber blanket is slightly larger than groove.
In use, can spur the free extension on the aluminium foil 3, to tear whole aluminium foil 3.Then, syringe needle can be passed the base material of rubber blanket 4 and groove and be inserted into the seal cover inboard.Under situation shown in Figure 2, owing to be provided with two rubber blankets, therefore one can be used to insert Medicated needle of syringe, and another can be used to insert infusion needle.
As can be seen, medical plastic compound seal lid of the present utility model only comprises one deck plastic cover, and the volume of rubber blanket is also less than the rubber blanket that almost equates with the transverse section of lid.Therefore, the consumption of plastics and rubber has all reduced.In addition, only need the single lid of injection moulding, so the course of processing is simplified.So, can reduce the cost of seal cover.
On the other hand, be two in the quantity of rubber blanket and can on the rubber blanket that is separated from each other, insert the syringe needle of different purposes when above, therefore can improve operating reliability.Simultaneously, tear the required power of aluminium foil far below drawing back the required power of draw ring, therefore operation is very easy.
Though described specific embodiment of the present utility model above, persons of ordinary skill in the art may appreciate that under the situation that does not break away from this utility model principle, can make various modifications to it.
