Atomatic saline bottle refilling system

In the process of medication, it is a common practice to treat patients with saline for dehydration and other medical ailments to improve the health condition of the patients. When fed with saline continuous observation of nurses is mandatory in monitoring the level of the saline. There are many cases where patients are being harmed due to the staff inattentiveness, as their absence does not notice the completion of saline level in the container. This arises the problem of back flow of blood immediately after the completion of saline in container. Hence to protect the patient from getting harmed a saline level monitoring system has been developed. The proposed model incorporates a level sensor which continuously detects the saline drops using LM358 comparator IC and Relay unit. Whenever the sensor detects low level of saline, it automatically off the trips bottle for safety of the patients and the saline bottle will be refill by secondary compartment (having saline) present in our system the addition future of this system having the small battery backup in power supply unit to keep the system alive when power cut is occurred. Through this system, doctors and caregivers are not necessary to monitor their patient anytime, anywhere.
