Extracorporeal membrane lung oxygenation catheter capable of avoiding lower limb ischemia

The invention discloses an extracorporeal membrane oxygenation catheter capable of avoiding lower limb ischemia, and relates to the technical field of medical instruments. Comprising a pipeline and a sleeve bag, the position, 6-9 cm away from the lower end of the pipeline, of the sleeve bag is fixedly connected, the pipeline is provided with a plurality of pipe holes in the sleeve bag, the sleeve bag is provided with a plurality of holes which do not correspond to the pipe holes in position, and the total cross section area of the holes in the sleeve bag is larger than that of the pipe holes; the blood leaked from the pipe hole still flows to the whole body although the heart pulsates and is located on the upper side of the lower limb artery, the situation that the blood of the lower limb is excessively infused due to the fact that only a far-end infusion pipe is applied to the lower limb artery is avoided, and the problem of lower limb artery ischemia caused by the fact that the pipeline is thick and occupie
