An inexpensive alarm and chock system for intravenous infusion process is significant for reducing the risk of excess fluid infusion and backflow of blood into the tube during intravenous infusion. The device is composed of three parts. The first part FIG. 1 is disposable and contains sensing metallic cap 3 and 6. The output 8 and 9 of first part is connected to the transistor 12 of second part. The output of transistor 12 is send to the NOT Gate 13. This NOT Gate 13 gives supply to the relay 14. The relay 14 activates the alarm 15 and motor 16 when output 8 and 9 leaves the contact with fluid. Motor 16 help in chocking the tube of infusion system with the help of clip 20. The components used for making this device are very inexpensive, which makes this as cost effective. This device does not require sterilization for the next use.
