As the number of punctures increases, the leakage becomes more serious, and the consumables need to be replaced. The existing models are generally placed in the simulated human chest cavity, which has the problem of inconvenient replacement of consumables, and the amount of effusion is difficult to judge, and the efficiency of fluid replacement by needle injection is very low.
