| I.P Abstract & Summary |
Therefore, the present disclosure has been designed to solve the above-mentioned problems, and it is an object of the present disclosure to provide a new branch adapter for an infusion set having a structure in which a block-shaped backflow prevention branch tube opening/closing tool, which is made of an elastic/flexible material such as silicon, is disposed inside a branch tube so as to close the branch tube, while the backflow prevention branch tube opening closing tool has a cutting line such that the branch tube is opened when a needle or a connection tube of an infusion tube/a human body-side syringe-connecting tube is inserted through the cutting line, whereby there is no need to provide and use a valve, easiness of manufacture and assembly is improved, manufacturing costs are reduced, and sealing efficiency of the branch tube is improved. |
