DESIGN AND CONSTRUCTION OF SALINE LEVEL DETECTION WITH ALARM

Abstract The objective of this work is to construct a saline level monitoring system to facilitate medical staffs in order to notify them when the saline level is almost empty or below the setting value.After installing the saline bottle to a load cell module, the load cell will be used to measure the weight of the saline. The weight from the load will be transferred to microcontroller to start alarming until the doctor notify the alarm and take an action. The are 4 tests to validate the performance of the developed system. The first test is performed by comparing between the weight measured with developed system and the weight of the standard weight. The results show the percentage errors between them are within 0.43%. the second test is to examine the relationship between the weight measured by the load cell and the saline volume dispensed from the infusion pump machine. The relationship between the average weights and the volumes is found to be approximately 1g per 1ml. The third test is carried out by comparing between the volume measured with the developed system and the volumes measured with the infusion pump system. The results indicate that the percentage errors are within 2.13%.finally,the finally the minimum volume detected by the developed system is found to be 4ml. The results indicate that the developed system is able to help in monitoring the saline volume in the bottle from a distance and give the notification when the saline level reaches the pre defined critical volume and will give alarm
