Lung expansion protection inflatable bag device for cardiac surgery operation and using method thereof

The invention discloses a lung expansion protection inflatable bag device for a cardiac surgery operation and a using method thereof. The lung expansion protection inflatable bag device comprises a lung bag and an airbag, wherein the lung bag is fixedly connected with one side face of the airbag; an opening is formed in one side of the lung bag; one side, far away from the lung bag, of the airbagis planar; an inflation tube is arranged on the airbag. The lung expansion protection inflatable bag device disclosed by the invention is simple in structure, ingenious in design and convenient to operate, expansion of unilateral lung can be inhibited by the lung bag, an elastic cord of the opening of the lung bag does not cause expansion cone slack due to the expansion of the unilateral lung, aneffect of the lung bag for inhibiting the expansion of unilateral lung is not influenced, the airbag can protect lung tissues after inflation, and an isolation protection effect can be achieved. 本发明公开了种心外科手术肺脏膨胀保护充气袋装置及其使用方法，其
