Lung capacity training device for rehabilitation therapy

Abstract

The invention relates to medical rehabilitation equipment technology and discloses a lung capacity training device for rehabilitation therapy. The device comprises a cylindrical hollow shell, an annular hollow block fixed to an inner wall of the shell, a detection component arranged on a left side of the inner cavity, and a lifting component arranged above the annular hollow block. The device integrates an electronic detection system and a mechanical indication system. Blowing pressure is detected by pressure sensors and converted into digital lung capacity values displayed in real time, enabling objective monitoring of rehabilitation progress. Simultaneously, pistons and scale rods provide intuitive visual and physical feedback through lifting movement, enhancing patient motivation and engagement. A detachable blowing component comprising an insertion pipe, limit plate, and blowing nozzle facilitates cleaning, replacement, and hygienic use during respiratory rehabilitation training.
