Embodiment Construction
[0015] The invention can not only realize the perfusion and soaking of the low-temperature lung preservation solution for the lungs, but also can perform intratracheal ventilation sequentially, and combine their respective advantages to improve the quality of the NHBD lungs. Specific use can be divided into three stages, as shown in Figure 2.
[0016] First, the donor lung receives low-temperature lung preservation solution perfusion, rapid cooling, and protection of vascular endothelial cells.
[0017] The donor opens the chest to take out the cardiopulmonary complex. After taking it out, relax the elastic opening 4 above the medical elastic rubber bag 1 and place it in the cardiopulmonary complex. The medical elastic rubber bag 1 is provided with a central fixing bracket 7 which is Used to support the donor cardiopulmonary complex, the fixing ring 6 is located at the end of the fixing bracket 7, which can fix the left and right bronchus, so that the cardiopulmonary complex is saf...
