Abstract
The present invention relates to a device for intravenous administration, and, more particularly, to an intravenous drip system capable of closing an outlet provided to a lower end of a drip vessel by lowering a floating valve in the drip vessel when a level of a medical solution filled in the drip vessel of the intravenous drip system falls down, thereby preventing air from flowing into a patent's vein.
Claims9
An intravenous drip system comprising:
- a port coupler configured to connect to a port provided to a medicine container to discharge a medical solution, and having a drip tube protruding from a center portion of a lower end thereof;
- a cylindrical drip vessel configured to engage to a lower flange of the port coupler, and having an inner space in which the medical solution dripped from the drip tube is temporarily stored, the cylindrical drip vessel being provided with an outlet at a lower end thereof;
- and
- a floating valve made of a material to float in the medical solution stored in the drip vessel, and having a floating cup suspending from the lower end of the drip tube, through-holes penetrating a lower end of the floating cup in a circumferential direction, and an air blocking valve engaged to the lower end of the floating cup,
- wherein the floating valve is detached from the drip tube by pressing both sides of the drip vessel, and if a level of the medical solution rises in the drip vessel, the floating valve goes up to open the outlet, while if the level of the medical solution drops, the floating valve goes down so that the outlet is closed by the air blocking valve.
