A device for simulating human breathing

Abstract

The invention discloses a human respiration movement simulator. The simulator comprises a base platform, an X-direction driving sliding platform fixed on the base platform, a Y-direction driving sliding platform fixedly connected with a driving end of the X-direction driving sliding platform, a Z-direction driving sliding platform fixedly connected with a driving end of the Y-direction driving sliding platform, a right-angle connecting rod with one end fixedly connected with a driving end of the Z-direction driving sliding platform, a chest wall movement simulation platform fixedly connected with the other end of the right-angle connecting rod as well as a simulation tumor spheroid, wherein the top and the bottom of the simulation tumor spheroid are correspondingly connected with a spring damper I and a spring damper II respectively, the spring damper I is fixedly connected with the bottom of the chest wall movement simulation platform, and the spring damper II is fixedly connected with the base platform. The simulator has the advantages that the three-dimensional correlation movement of the chest wall and an inside tumor during human respiration is reproduced, a more accurate movement model and a more accurate verification tool are provided for tumor radiotherapy respiration tracking study, and the simulator is used as a medical teaching or scientific research instrument.

Description

technical field [0001] The invention belongs to the field of auxiliary simulation devices for medical equipment, and in particular relates to a human breathing motion simulation device for precise radiotherapy experimental research. Background technique [0002] Radiation therapy is an excellent way to treat tumors non-invasively and quickly. In recent years, image-guided precision radiation therapy technology has become the development trend of tumor radiation therapy. Obtaining images of target areas through CT and X-rays and performing precise registration greatly improves the Accuracy of positioning and dose delivery in radiation therapy. [0003] However, most of the organs and tissues in the human thoracic and abdominal cavity are not static. Respiration, heartbeat and gastrointestinal peristalsis will cause the implicated movement of the thoracic and abdominal tumors, which brings difficulties to the precise positioning of the tumor target. The precise location of th...

Problems solved by technology

However, some linear slide drive simulators can only simulate the two-dimensional movement of the chest wall, and some can simulate the three-dimensional movement of the chest wall but cannot realize the correlation between chest wall movement and tumor movement

Due to the complex internal structure of the high-fidelity human simulator, it is inconvenient to directly obtain the movement trajectory signal of the internal tumor
