The present invention relates to a medical device for intravenous injection, and more particularly to a medical device for intravenous injection for safe and convenient supply of a certain amount of injection to the patient from the infusion container located on the upper part of the patient.

In general, patients who are unable to adequately receive essential nutrients by mouth can maintain fluids, electrolytes, vitamins, proteins, fats and calories, maintain proper blood components, or take medication quickly in an emergency. In order to supply the hospital is administered intravenous fluids or drugs in the vein of the patient, such as intravenous injection, the IV set is commonly used as an essential item.

In recent years, as medical technologies are diversified and methods are changed, more than two bottles of fluids or injections are injected at the same time. For this purpose, a 3-way connector is connected to a plurality of IV sets, and a patient's vein is injected through a syringe or a catheter. The method of supplying to

To do this, nurses use different products, that is, multiple IV sets and 3-way connectors, which are interconnected and do not match each other, when fluids are injected, or when there is a problem in the patient's blood vessels. Or in case of severe movement of the patient to fix the junction using a band-aid or the like. However, when the joint portion of the adhesive band falls due to the movement of the patient or the hydraulic pressure acting on the joint portion exceeds the fixing force, the fixing portion is separated and the products are frequently separated.

Recombination may be attempted in the event of such an accident, but the new IV set and 3- may be recombined rather than rejoined due to the possibility of contamination due to the possibility of contamination due to contact with the air that is not removed cleanly with the band-aid joint. It is common to have a way back to the initial stage of preparation. However, in this case, unnecessary time is generated due to removal and retry, and there is an uneconomic problem because the article is used in duplicate.

In addition, if the product is dropped out, the patient's bedding, sheets, and hospitality are polluted with various fluids and patients' fatigue, giving unnecessary discomfort to the patient and family, and a lot of time and economic requirements due to replacement and washing. However, in severe cases, complaints may arise from the patient's family.

Accordingly, the present invention has been made to solve the above problems of the prior art, an object of the present invention is to integrally combine the multi-way connector to the IV set, the tube of the other IV set to the auxiliary inlet pipe of the multi-way connector The present invention provides a medical device for intravenous injection, which is provided with a screw coupling tool capable of screwing the distal end, thereby fundamentally preventing the separation between the various devices necessary for intravenous injection.
