Clinical vital capacity training device for respiratory exercise

The utility model relates to the technical field of medical instruments, in particular to a clinical vital capacity training device for respiratory exercise, which comprises a flow tube, the outer side of the flow tube is fixedly connected with a plurality of communicated sliding tubes, and the sliding tubes are uniformly distributed. The ends, away from the flowing pipe, of the multiple sliding pipes are fixedly connected with the same output pipe, and an air blowing assembly is arranged at one end of the output pipe. The air blowing assembly comprises an air blower fixedly connected with one end of the output pipe, and the outer side of the air blower is fixedly connected with a supporting block. The air blowing device is reasonable in structure, the hollow ball slides into the output pipe from the corresponding sliding pipe according to the amount of blown air, the hollow ball flows back into the communicating pipe through the output pipe and the backflow pipe, according to the distance between the differe
