Abstract: Abstract The present invention relates to a compact borewell rescue suction mechanism (100) configured for rescuing a trapped child from a narrow and deep borewell by removing debris surrounding the child and continuously monitoring the child’s condition during rescue operations. The system (100) comprises a suction assembly (101) having a vacuum motor unit (102), a flexible suction pipe (103), and a debris collection chamber (104) adapted to suck loose soil, sand, dust, stones, and other obstructive materials present around the trapped child. The suction assembly (101) is designed to operate safely within confined borewell spaces without causing physical harm to the child. The rescue mechanism (100) further comprises an oxygen delivery module (105) connected to an oxygen cylinder or oxygen storage unit (106) for supplying breathable oxygen to the trapped child for a minimum duration of one hour. A rechargeable battery backup unit (107) is electrically connected to the suction assembly (101), oxygen delivery module (105), and monitoring components to ensure uninterrupted operation during rescue procedures. The system additionally includes a compact infrared (IR) camera module (108) positioned near the suction assembly (101) for capturing real-time visual data of the child and surrounding borewell environment under low-light or dark underground conditions. A data transmission unit (109) is operatively connected to the IR camera module (108) for transmitting live video, movement data, and rescue status information to an external monitoring station or control monitor (110). The mechanism may further include LED illumination units (111), environmental sensors (112), and a remote-control interface (113) for precise positioning and operation. The disclosed invention enables safe debris removal, continuous oxygen support, real-time monitoring of child movement, and enhanced rescue coordination, thereby reducing rescue time and improving the success rate and safety of borewell rescue operations
