The invention relates to the technical field of
breathing exercise, and discloses a
lung cancer patient assisting
breathing exercise device which comprises a hollow block, the hollow block communicates with the top of the left side of a
mask, the inner side of the hollow block is rotationally connected with a gear, and the top of the inner side of the
mask is fixedly connected with a
piston. The bottom of the
piston is rotationally connected with a first threaded cover, the outer side of the first threaded cover is fixedly connected with a gear ring, the gear ring is in meshed connection with the gear, the middle of the top end of the
piston is communicated with a one-way valve, and the inner side of the first threaded cover is in threaded connection with a threaded ring. The one-way valve is opened to prevent suffocation when a user wears the
mask to breathe and inhale, the one-way valve is closed when the user expires, the piston moves along with
breathing, the spring stretches out and draws back to generate elastic force to form breathing resistance, the user is promoted to breathe forcefully to achieve exercise, the gear is rotated to drive the gear ring and the first threaded cover to rotate, the threaded ring and the lifting disc move, and the breathing resistance can be adjusted visually and accurately.
