Fully functional device design and developed at NID-Gandhinagar,sponsored by Motorola. This device is useful to prevent the bubble entering into body by the syringe which is used for feeding the bottle fluid to the patient. A versatile principle of physics is applied, that is infrared rays absorbed in liquid. This principle helped us to develop a sensor which is used along with the transparent pipe passing liquid to patient. If liquid is present controlling device will not be in operation, if liquid is not there controlling device will come into action by actuation electro-mechanical actuator to closed the pipe thus avoiding air bubble to pass into the body and avoiding blood spoiling. At this moment this device makes a call to nurse using mobile device. This device is utilizing state of the art solid state electronic controlling circuit sensor and electromechanical device.
