CONNECTION TIP FOR INJECTING MEDICATION AND CONNECTION TIP FOR DRAWING MEDICINE AND CONTAINER I.V. SOLUTION HAVING THE SAME}

The present invention relates to an infusion container, and more particularly, in the case of injecting a chemical solution into an infusion container or extracting a sap, by preventing contact between the elastic body and the medicine or sap at the connecting tip to secure the stability of the sap or the sap. The present invention relates to a chemical liquid input connection tip and a fluid extraction lead that can prevent adverse effects on a patient in advance, and a fluid container set having the same.

Typically, sap, such as physiological saline solution or glucose solution, administered to a patient when operating or treating a patient in a hospital, is stored in some form of medical container. Such sap containers are roughly classified into glass bottles, polyvinyl chloride (PVC) bags, or so-called non-PVC bags, polymer multilayer film sap bags, etc., which are not made of polyvinyl chloride.

Conventionally, many glass bottle sap containers have been used because of material advantages, but glass bottle containers are bulky, fragile, and have heavy weights, such as PVC bags or non-PVC bags. Sap bags made of synthetic resins are used a lot. The sap bag is easy to handle because it does not have to be broken at first, and because of the advantages of easy storage and transportation, the sap container market is rapidly being replaced by a synthetic sap bag.

The sap bag is provided with a port for inserting a spike used to drain the contents or a syringe for injecting a drug.

The tip is usually installed by plugging into a synthetic drain tube that is integrally molded with the sap bag.

The sap bag port that has been used conventionally is a connector made of hard synthetic resin, a rubber body assembled into the connector, and aluminum mounted on the rubber body, as shown in "Korean Utility Model Publication No. 223435". Or it is made of a hard synthetic resin cap, the upper surface of the cap is usually configured in the form of a sealing paper attached to the cap or film for preventing tampering.

The connecting body is installed with a tip penetrating the rubber body to inject a drug into the sap in the sap bag or withdraw the sap to the patient side.

Thus, the tips fitted to the connecting body in the sap bag are combined with the sap bag by fitting through the rubber body.

Typically, in the case of the sap bag, a set of infusion including a spike and an injection needle are fastened to a tip installed in the connecting bag formed in the sap bag, thereby providing a passage of the chemical liquid.

In addition, such a rubber body is provided to fix it.

Therefore, the chemical liquid or the sap has a problem that physical contact with the rubber body is inevitable.

Because of this, research on the aluminum contamination of parenteral nutrient sap showed that the most aluminum was eluted from the glass container used before the plastic sap bag, and the aluminum was also eluted from the rubber stopper for sealing.

Therefore, when aluminum is eluted in sap, it accumulates in bone in the body and shows strong neurotoxicity. In the case of glass containers, the plastic sap bag was replaced to reduce the risk.

However, conventionally, there is a problem that can not prevent the contact of the chemical or sap and the rubber body.

Accordingly, in recent years, in order to solve the above problems, the silicone is coated on the outer surface of the rubber body.
