The intravenous fluid flow monitor and control device is claimed in claim 1, operated using under a battery mode and/or an alternating current power mode. The intravenous fluid flow monitor and control device is claimed in claim 4, the battery mode automatically switch over when the alternating current power mode interrupted. The intravenous fluid flow monitor and control device is claimed in claim 1, the device provisioned as a detachable device. The intravenous fluid flow monitor and control device is claimed in claim 1, provisioned to operate remotely using a mobile phone-based application programming interface and/or web-based cloud application programming interface.
The intravenous fluid flow monitor and control device is claimed in claim 7, wherein said application programming interface provisioned to manage a plurality of similar intravenous fluid flow monitor and control devices. The intravenous fluid flow monitor and control device is claimed in claim 1, provisioned to operate under a manual mode. The intravenous fluid flow monitor and control device is claimed in claim 1, provisioned with a unique identity number. The intravenous fluid flow monitor and control device is claimed in claim 1, wherein the potentiometer supports a calibration adjustment. The intravenous fluid flow monitor and control device is claimed in claim 1, wherein said intravenous fluid flow monitor and control device and method of monitoring and controlling of intravenous tube fluid comprising steps of: setting a desired fluid drip flow rate or fluid drip duration or quantity of fluid using a mobile phone interface and/or a web-based interface and/or a manual interface; regulating or compensating an additional fluid flow by moving in a forward direction of a motor, that compresses an intravenous tube; allowing or regulating a fluid flow by moving in a backward direction of the motor, that releases the intravenous tube; displaying current fluid flow rate in a display unit; displaying a battery level, a plurality of wireless communication interfaces, a room temperature, a room humidity, a device identity number in the display unit; issuing of an alert message in the display unit and in the mobile phone interface and in the web-based interface when the device finds an abnormal conditions, including: when the infusion is performed completely; when the saline bottle is empty;
when there is no fluid flow; when the device finds an air bubble; when the device finds a blockage or clog in the tube; when the battery level below to 15 % or user preferred level; when there is a power failure; when the infusion time has elapsed; and when it finds a malfunction, stopping the infusion and raising an alert message on the conditions, including: when the saline level reaches 5 % or user preferred residual level; when the device detects an air bubble presence; when the infusion is completely performed; when there is no fluid flow; when the device finds a blockage or clog in the tube; when the infusion time has elapsed; and when it finds a malfunction.
