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.

The present invention relates to a medical drain unit comprising: a drain port installed in an infusion solution container; and a drip chamber detachably coupled to the drain port and discharging an infusion solution stored in the infusion solution container. More specifically, the present invention relates to a medical drain unit having a luer-lock connection structure, in which a rubber stopper having a cut incision and a first coupling pipe exposing the incision are installed in the drain port; and a second coupling pipe coupled to the first coupling pipe and a luer-lock connector including an insertion tube which is inserted into the incision to discharge the infusion solution are installed in the drip chamber, whereby a spike that is forcedly inserted into the rubber stopper is not required.

Methods and devices for monitoring and/or controlling delivery of a fluid to a patient monitor a level of the fluid and generate an alarm and/or block flow of the fluid through a flexible delivery tube to the patient in response to detecting that the fluid level has dropped below a predetermined level. A device for monitoring and/or controlling delivery of the fluid to a patient is removeably mountable to a fluid delivery assembly having the delivery tube. When the device is configured to control delivery of the fluid, the device automatically reconfigures from a first configuration in which fluid is allowed to flow through the delivery tube to a second configuration in which the delivery tube is in a deformed state via the device to block flow of fluid through the delivery tube upon the device detecting that the fluid level is below the predetermined level.

A system and a method are adapted for assessing the patency of a fluid infusion line connected to a patient, a source of medicant, and a pump. The system is configured for injecting a fluid into the fluid pressure line using a syringe, determining whether the syringe exhibits a resistance to fluid being injected into a the fluid line and, if no resistance is exhibited, monitoring the pump to verify whether the pump exhibits an alarm that indicates a check valve has been opened.

A drip chamber is described that is used in medical infusion therapy, wherein the drip chamber utilizes valving to control flow of one or more fluids to a patient. The drip chamber includes a body forming a chamber, wherein fluid may enter via two or more flow ports, and an output port, where fluid may exit the chamber. A float controls fluid flow through one or more flow ports into the chamber such that the flow exiting the chamber may be limited to a single fluid or a combination of the fluids entering the chamber. The float is configured to be retained within the chamber, and the float moves within the chamber based on a level of fluid within the chamber. The control characteristics of the float are determinable by attributing specific buoyancy and dimensions to the float.

A fluid delivery Y-site is described that is configured to receive and control delivery of two or more fluid flows. Fluid flow is controlled within a chamber by a valve and float. Flow of a primary fluid into the chamber is reduced or halted by the movement of a valve. The valve may occlude a first flow port into the chamber in response fluid flowing from a second flow port into the chamber. A float is moveably disposed within the chamber and configured to engage the valve in response a fluid flow into the chamber from the second flow port. As fluid flow from the second flow port into the chamber is reduced or ceases, the valve and float allow the flow from the primary flow port to once again enter the chamber and exit from an outlet port.
