This invention discloses a suction device for treating otitis media in children, belonging to the field of otitis media treatment technology. It comprises a fixed spring, a connecting sleeve, a suction catheter, a fixed needle sleeve, and a clamping sleeve. After the fixed block on the inner wall of the clamping sleeve aligns with the arc-shaped groove, releasing the connecting sleeve causes the first moving block to reset within the strip-shaped mounting groove under the rebound of the fixed spring. This moves the connecting sleeve from the mounting sleeve surface to the clamping sleeve surface, while simultaneously squeezing the clamping sleeve to clamp it onto the fixed needle sleeve surface until the fixed block engages in the annular groove. At the same time, the connecting sleeve is pressed against the limiting block, causing the inner wall of the connecting sleeve to squeeze the second rubber retaining ring, thus clamping and fixing the connecting sleeve onto the clamping sleeve surface. This ensures that when the suction needle is inserted into the child's ear canal for suction treatment, the fixed needle sleeve will not detach from the suction catheter surface due to the child's struggles.
