Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0033] The specific control mode of simulating human lung respiratory movement in the present invention is: collect the airflow flow signal of the simulated lung cavity ventilation port through the flow sensor; transmit the collected flow signal to the built-in AD microcontroller for analysis and processing to generate the motor drive signal , according to the motor drive signal to control the forward and reverse rotation of the motor and the speed of the rotation speed, and then further control the stretching motion of the pulling rope, and finally control the breathing motion of the simulated lung cavity;

[0034] The above self-contained AD microcontroller sets the breath-to-breath ratio (R I / E ), respiratory rate (f res / min), tidal volume (VT), vital capacity (VC) and other respiratory physiolo...

Abstract

The invention belongs to the field of study on respiratory physiology and discloses a device and control method for simulating the spontaneous respiratory movement of the human lung. The device comprises a simulated lung cavity, springs, a pull rope, a flow sensor, a touch display screen, a motor driver, a direct-current servo motor and a control circuit. The respiratory physiological parameters including the inspiration and expiration ratio, the respiratory rate, the tidal volume and the vital capacity are input through the touch display screen; the flow of air passing by the air change port of the simulated lung cavity is detected by the flow sensor; a motor control signal is triggered by a microcontroller according to the set respiratory parameters and the detected flow signal; further the reeling and the unreeling of the pull rope are controlled by the motor; and finally the respiratory movement of the simulated lung cavity is controlled. The device disclosed by the invention is more in line with the respiratory physiology of the human lung and has extremely high application values in the aspects of scientific research, teaching and respiratory-related product testing.

Description

technical field [0001] The invention relates to the field of respiratory physiology and medical research, and more particularly, to a movement device and control method for simulating the spontaneous breathing of human lungs. Background technique [0002] Respiratory motion is a complex process, and the parameters used to characterize respiratory motion are: respiratory-expiratory ratio (R I / E ), respiratory rate (f res / min), tidal volume (VT), vital capacity (VC) and other respiratory physiological parameters. [0003] Most of the existing devices for simulating the breathing function of human lungs are based on manual and passive simulation of human lung breathing movement. This method is difficult to accurately and quantitatively control the breath-to-breath ratio (R I / E ), respiratory rate (f res / min), tidal volume (VT), vital capacity (VC) and other respiratory physiological parameters. Contents of the invention [0004] In order to overcome the deficiencies of...
