AN INTRAVENOUS DRIPPER SYSTEM FOR AUTOMATIC MONITORING, CONTROLLING AND NOTIFICATION OF A
FLUID
FIELD OF INVENTION
[0001] The subject matter described herein, in general, relates to an intravenous fluid infusion system for convenient administration of intravenous fluid, and in particular, relates to an improved, cost-effective system of sensing and controlling the medication of intravenous fluid in a non-invasive manner during anesthesia or surgery. BACKGROUND OF INVENTION
[0002] Methods of monitoring the drip rate in any conventionally existing intravenous fluid infusion apparatus requires gravity infusion of parenteral solution that is accomplished by suspending the solution container several feet above the patient and connecting the drip chamber to the venepuncture site via a flexible delivery tube. The pressure difference created across the drip chamber and the venepuncture site causes flow of solution through the flexible delivery tube into the veins of the patient, especially those undergoing anesthesia and surgery.
[0003] This is a most commonly known hospital set up of administering of Intravenous (IV) fluids, which largely remains under the supervision and control of hospital nurses or attendants. Most often, the ratio of nurses attending the admitted patients is profoundly low, sometimes as low as 1 nurse

chaperoning almost 40 patients at a time. Consequently, these nurses are vulnerable to elevated stress levels owing to huge work load, which inevitably introduces a factor of human error. A nurse leaving the patient unattended for a long time may cause administration of excess quantities of IV fluids, which is both undesirable and deleterious leading to unnecessary and fatal complications.
[0004] Despite its wide usage and importance, not much automation has been introduced/achieved in the system of intravenous drippers during the last few decades. The currently existing manually governed bare bones IV drip system may lead to occurrence of air embolism and blood back flow if the intravenous administration of fluid to a patient is not frequently attended to. When intravenous fluid is admitted to the patient by gravity fed system there is chance that the dripper chamber runs out of fluid and air bubble might enter the patient's blood stream, thereby causing air embolism. Due to pressure difference the blood also has the chances to flow back into the empty tube, thus causing back flow.
[0005] In the background of foregoing limitations, there exists a need for a system that is capable of autonomous administering of intravenous administration of fluid to a patient from a drip chamber whereby the continual

attending of the patient by the nurses may be obviated, and fatal consequences of air embolism and blood back-flow may be negated.
OBJECTS OF THE INVENTION
[0006] The primary of intravenous infusion of drug into veins of patient during anesthesia or surgery.
[0007] A main object of the disclosure is to provide a cost-effective system of administration of intravenous fluids that permits automatic monitoring and control of fluid required to flow into patient.
[0008] Another object of the disclosure is to provide a convenient and easy method of maintaining steady flow rate of fluid through an intravenous infusion system in a clinical setting to avoid any medical irregularities.
[0009] Yet other object of the present disclosure is to provide an automated, cost-effective, modular and replaceable system of sensing and controlling intravenous fluids in an IV drip set thereby assisting the nurse in effective management of multiple patients at one point of time.
[00010] In yet another embodiment, the disclosure provides a simple, albeit smart system of sensing and blocking the medication or IV fluid to avoid any occurrence of air embolism or blood back-flow.

[00011] Still another embodiment of present disclosure provides enhanced versatility in real-time monitoring of parenteral fluid at a stable rate over the prescribed period of time.
[00012] In still other object of the present disclosure, the system can be replicated over multiple drippers that will allow these drippers to communicate and transmit information for flawless monitoring of multiple patients by a single nurse via any form of display desired by the user of such system.
[00013] The other objects and advantages of the present invention will be apparent from the following description when read in conjunction with the accompanying drawings, which are incorporated for illustration of preferred embodiments of the present invention and are not intended to limit the scope thereof.
