Description

CONNECTOR FOR BRANCHING OFF FLUID INFUSION [0002]

The present invention relates to a connector for liquid branching, and more particularly to a connector for liquid branching for filtering fine foreign substances contained in a chemical liquid of a syringe.

In general, patients who are unable to adequately ingest essential nutrients will be given sap. The fluid is parenterally (non-orally) supplied as an artificial solution such as a mixture of water and electrolyte, a carbohydrate, an amino acid solution, a glucose solution, a plasma net, a dextran, an erythrocyte suspension, or the like, .

In order to inject such a liquid into a patient, it is necessary to use a liquid medicine to be injected into the liquid tube for injecting the liquid medicine into the needle hub, a needle hub to which the swabs are fixed, a sap tube for injecting the sap into the vein or subcutaneously, A connector, a liquid container for supplying the liquid to the tube, or the like can be used.

For example, the swiss knees are inserted into the vein of the patient, the swiss knees are connected to the sap tube through the needle hub, and the sap in the sap is supplied to the patient through the sap tube.

However, when a separate chemical liquid is injected into the liquid tube through the connector, fine glass particles in the liquid medicine, for example, fine glass particles or impurities generated from injections of the glass ampule type can be administered to the patient together with the liquid , Which may cause additional illnesses such as phlebitis in the patient.
