Abstract

A disposable infusion bag includes a bag body (2), an infusion connector (1) and a drug filling connector (9) which are arranged on the bag body (2), the drug filling connector (9) and the infusion connector (1) are respectively arranged at the both ends of the bag body (2), the utility model is characterized in that, the drug filling connector (9) includes a drug filling soft tube (7), a first end part of the drug filling soft tube (7) extends into the bag body (2), a second end part is provided with a fork (10), one end of the fork (10) is provided with an air port (6), and the other end is provided with a drug filling port (5). Compared with the prior art, the utility model has the advantages of that, the structure of the infusion connector and a drug filling connector which are arranged at the both sides of the bag body, as well as the independent air port, can ensure the infusion speed, at the same time, the utility model can reduce the possibility of bacterial infection and facilitate the use for the medical staff during the operation process.

Description

A kind of disposable infusion bag

Technical field

This utility model relates to instrument used for injection in a kind of medical treatment, relates in particular to a kind of disposable infusion bag.

Background technology

Existing disposable medical transfusion bag, its structure comprise the bag that is used to store medicinal liquid, are located at transfusion interface and injection interface on the bag, and transfusion interface and injection interface often are located at the same side, and the injection interface generally is provided with small plastic head or rubber closure.There is following deficiency in this kind design, and first, do not have a special blow vent, generally inject air by medicine-pouring port, need during injection hold up bag come, can not keep flat, so the injection process seems cumbersome, and medicine-pouring port enters antibacterial easily; Second, seal medicine-pouring port owing to adopt small plastic head or rubber closure, during injection, small plastic head or rubber closure enter syringe needle easily, enter into medicinal liquid when injecting then easily and go, and pollute medicinal liquid, further cause potential infection, cause blood vessel embolism or pulmonary infarction in the serious intravasation, injection also can cause cerebral embolism in Arterial system, directly jeopardizes patient's life; Three, because operation takes longlyer, infusion needle open-assembly time just prolongs relatively, has increased the chance of polluting.

Someone has proposed some improvement to existing disposable infusion bag; as Chinese utility model patent: ZL99209939.0; a kind of " disposable soft packing transfusion bag " (publication number: 2375300Y) is disclosed; its feature is to install a bit of flexible pipe respectively additional at the two ends of bag; be provided with barrier film in the flexible pipe; the sterility protection medicated cap is equipped with at the external port place of flexible pipe; two short length of flexible are respectively applied for injection and transfusion; infusion process becomes more convenient like this; reduce the possibility of liquid medicine contamination, also solved the medicinal liquid leakage problems.But the air inlet is not independently setting still, though the inconvenient also existence still of minimizing that has is gone up in may and operating of liquid medicine contamination.

The utility model content

Technical problem to be solved in the utility model provides a kind of easy to operate, disposable infusion bag that the liquid medicine contamination probability is minimum.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of disposable infusion, it comprises bag, is located at transfusion interface and injection interface on the bag, and injection interface and transfusion interface are located at the two ends of bag respectively, it is characterized in that aforesaid injection interface comprises the injection flexible pipe, the first end of injection flexible pipe stretches into bag, the second end is provided with bifurcated, and this bifurcated one end is provided with blow vent, and the other end is provided with medicine-pouring port.

Be used to control the medicinal liquid of injection flexible pipe, described injection interface also comprises the actuator of being located on the injection flexible pipe.

For purifying air, but be provided with the sponge of air filtering in the described blow vent.

Not contaminated for the protection medicine-pouring port, described medicine-pouring port is provided with removable lining lid.

Described lid is the calparine cap with connecting portion and airtight portion.

Compared with prior art, advantage of the present utility model is: transfusion interface and injection interface are arranged at the structure of bag two ends and independent blow vent, guaranteed transfusion speed, reduced the possibility of bacterial infection simultaneously, it is more convenient to use that medical personnel also seem in operating process; The design of sponge in the blow vent has in time reduced airborne germ contamination, the medicine-pouring port calparine cap the further pollution that brings to medicinal liquid because of the injection process that reduced is set, also avoided granule to be injected into the generation of human vas situation by syringe needle.

Description of drawings

Fig. 1 is the structural representation of embodiment.

Fig. 2 is that the A of insert among Fig. 1 is to zoomed-in view.

The specific embodiment

Embodiment describes in further detail this utility model below in conjunction with accompanying drawing.

With reference to figure 1 and Fig. 2, disposable infusion bag in the present embodiment, it comprises bag 2, is located at transfusion interface 1 and injection interface 9 on the bag 2, and injection interface 9 and transfusion interface 1 are located at the two ends of bag 2 respectively, injection interface 9 comprises medicine-pouring pipe 7 and the actuator of being located on the medicine-pouring pipe 78, and the first end of medicine-pouring pipe 7 stretches into bag 2 bottoms, and the second end is provided with bifurcated 10, these bifurcated 10 1 ends are provided with blow vent 6, and the other end is provided with medicine-pouring port 5.Wherein, actuator 8 is a clip of establishing inhomogeneous duct in one, promotes medicine-pouring pipe 7, can realize the adjusting of injection speed, also can block flowing of medicinal liquid fully.Medicine-pouring pipe 7 stretch into bag 2 and expose in part be that plastic flexible pipe is made, bifurcated 10 parts are band tubing.

But 6 li sponges 31 that are provided with air filtering of blow vent, sponge 31 is installed on the blow vent 6 by an insert 3,

Medicine-pouring port 5 is provided with removable lining lid 4, and lid in the present embodiment 4 adopts has connecting portion 42 and airtight 41 calparine cap, and connecting portion 42 inwalls are provided with screw thread, accordingly, medicine-pouring port 5 outer walls are provided with screw thread, and airtight 42 is adopted rubber closure, during injection, as long as syringe needle is passed rubber closure; The bore of medicine-pouring port 5 can be selected to use according to syringe needle, and as 2cc, 5cc, 10cc, 20cc, 30cc, 50cc etc., air pressure and ambient pressure in the transfusion bag are regulated by passage.
