Abstract
The utility model discloses a drug injection combined cap for a soft infusion bag, which comprises a body and a rubber plug. The body is provided with a barrier type through hole which is divided into a rubber chamber and a flow passage through a partition, and the rubber plug is disposed in the rubber chamber which is sealed through an easy-tear aluminum film tightly attached to an upper opening of the body. One end, fused with the soft infusion bag, of the body is diamond-shaped. The drug injection combined cap is simple in structure, low in price, safe and reliable, and is convenient and quick as the combined cap can be used once the easy-tear aluminum film is torn away.
Description
Technical field
This utility model relates to a kind of medical package material, is specifically related to a kind of injection composite cover that is used for the soft bag of medical transfusion.
Background technology
The dosing plug device that present America and Europe and developed country are used for transfusion flexible bag is to adopt one section flexible catheter of thermal weld on the non-PVC-soft-bag, and medicinal liquid pours in the bag from conduit, and then grafting transfusion cork and dosing plug device, forms the transfusion flexible bag packing of a sealing.This transfusion flexible bag mainly has the connecting pin top of liquid stream through hole to embed rubber bodies by the centre with the dosing plug, put aluminium-plastic cap or polypropylene plastics cap seal mouth, that this transfusion flexible bag has is in light weight, transportation, automatic retraction does not need air inlet, is difficult for causing advantage such as cross infection when using easy to carry, transfusion, thereby has obtained extensive use.But its design also exists some problems: this structure need connect by conduit, has improved the cost of material; Rubber bodies directly contacts with medicinal liquid, can pollute medicinal liquid; Need aluminium alloy lid distortion closing in compression plug to reach sealing effectiveness at seal process, aluminum is considered to be worth doing, microgranule because of distortion closing in friction can produce and aluminium alloy covers in seal process, these aluminum bits, microgranule enter into medicinal liquid in seal process, medicinal liquid is polluted, and serious meeting produces malpractice.These problems cause no small potential safety hazard, have influenced the popularization development of transfusion flexible bag.
Therefore need a kind of energy of design to eliminate above-mentioned hidden danger, and single, easy to operate between structure, cheap transfusion flexible bag injection composite cover.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of safe and practical transfusion flexible bag injection composite cover.
Technology of the present utility model mainly is: a kind of transfusion flexible bag injection composite cover, comprise body, rubber stopper, and described body is provided with baffle type and runs through through hole, and described baffle type runs through through hole and is divided into rubber chamber and fluid course by shaping piece; Described rubber stopper places rubber indoor, easily tears the aluminum film phonograph seal by what be close to the body upper port; Described body be used for the interfused end of transfusion flexible bag be rhombogen.
As improvement of the technical scheme, the thickness of described shaping piece is between 0.25 ~ 0.35mm.
As improvement of the technical scheme, an end section of described body rhombogen is a rhombus, and its acute angle place is provided with extends the fusion limit, and the place, obtuse angle adopts arc transition.
As improvement of the technical scheme, described rubber stopper is the hat-shaped of hollow, and its top is provided with the acupuncture locating ring.
The beneficial effects of the utility model are: owing to adopt said structure, the diamond-shaped body structure of body lower end can directly fuse with transfusion flexible bag this transfusion flexible bag, engages solid and reliable, good airproof performance with the injection composite cover; Baffle type runs through through hole has avoided medicinal liquid to contact with rubber stopper; Easily tearing the use of aluminum film has avoided the acupuncture position of rubber stopper to expose in air.This utility model product structure is simple, cheap, safe and reliable, tears easily to tear the aluminum film and can use, and is convenient and swift.
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Fig. 1 is a upward view of the present utility model;
Fig. 2 is along the cutaway view of A-A line among Fig. 1;
Fig. 3 is the aluminum film front view that easily tears of the present utility model;
Fig. 4 is a rubber stopper front view of the present utility model;
Fig. 5 is along the cutaway view of B-B line among Fig. 4.
The specific embodiment
With reference to Fig. 2, a kind of transfusion flexible bag injection composite cover of the present utility model comprises body 1, rubber stopper 2, and described body 1 is provided with baffle type and runs through through hole, and described baffle type runs through through hole and is divided into rubber chamber 10 and fluid course 11 by shaping piece 12; Described rubber stopper 2 places in the rubber chamber 10, seals by the aluminum film 3 that easily tears that is close to body 1 upper port; Described body 1 be used for the interfused end of transfusion flexible bag be rhombogen.Owing to adopt said structure, the diamond-shaped body structure of body 1 lower end can directly fuse with transfusion flexible bag this transfusion flexible bag, engages solid and reliable, good airproof performance with the injection composite cover; Baffle type runs through through hole has avoided medicinal liquid to contact with rubber stopper 2; Easily tearing the use of aluminum film 3 has avoided the acupuncture position of rubber stopper to expose in air.This utility model product structure is simple, cheap, safe and reliable, tears easily to tear the aluminum film and can use, and is convenient and swift.
With reference to Fig. 2, shaping piece 12 is structure as a whole with body 1, and the baffle type that body 1 is provided with by shaping piece 12 runs through through hole and is divided into rubber chamber 10 and fluid course 11, has avoided medicinal liquid to touch rubber stopper 2.The thickness of shaping piece 12 is set to 0.25 ~ 0.35mm, can directly pierce through injection with injection needle during use.
With reference to Fig. 1, Fig. 2, the latter half of described body 1 is set to the rhombogen of hollow, and its cross section is roughly rhombus, and the centre is a fluid course 11.Rhombohedral four faces are straight thermal fusing surface, and its acute angle place is provided with extends fusion limit 13, and the place, obtuse angle adopts arc transition.Body 1 merges by straight thermal fusing surface and transfusion flexible bag, can make it bonding more firm; It is excessive that the extension fusion limit 13 at acute angle place can make the film of transfusion flexible bag when welding can not be stretched, and body 1 is better engaged with transfusion flexible bag; Adopt arc transition on the obtuse angle, avoided the broken transfusion flexible bag of sharp corners wearing and tearing or file.
With reference to Fig. 4, Fig. 5, rubber stopper 2 is set to the hat-shaped of hollow, and its top is provided with acupuncture locating ring 20, and during use, injection needle can thrust from the acupuncture position of 20 of acupuncture locating rings easily and carry out injection.
Further, as shown in Figure 2, this utility model has also adopted and has easily torn the upper port that 3 heat-sealings of aluminum film are close to body 1, and rubber stopper 2 is sealed in the rubber chamber 10, has avoided its acupuncture position to expose in air.As Fig. 2, shown in Figure 3, the shape of easily tearing aluminum film 3 is set to when being close to body 1 upper port, also has part to extend out, and tears during convenient the use.
The above only is a preferential embodiment of the present utility model, as long as realize that with basic identical means the technical scheme of this utility model purpose all belongs within the protection domain of the present utility model.
