Active breathing control system

Abstract

The invention discloses an active breathing control system which comprises a control box, a handle controller, an airbag, an airbag controller, a respiration sensor, a body temperature sensor, a heart rate sensor, a blood pressure monitor, an LED lamp and a control host machine. The airbag controller is connected to the airbag. The control box is connected to the airbag controller and is used for controlling the airbag controller to allow the airbag to be inflated or deflated. The handle controller is arranged between the control box and the air controller and is used for manually controlling the inflation and deflation of the airbag. The respiration sensor, the body temperature sensor, the heart rate sensor, and the blood pressure monitor are connected to the control box. The LED lamp is connected to the control box and is started when the airbag is inflated. The control box is connected to the control host machine which is used for emitting a beam closing command to a linear accelerator according to the signals monitored by the body temperature sensor, the heart rate sensor, and the blood pressure monitor. According to the system, the closing of a ray beam can be timely controlled, and the effect of precise radiotherapy is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an active breathing control system. Background technique [0002] The basic requirements of precise tumor radiotherapy technology are high precision, high dose, high curative effect and low damage. During the treatment process, the change of the position of the tumor target area due to the movement of organs, especially respiratory movement, will have a serious impact on the treatment. . In order to overcome the influence of breathing movement on tumor radiotherapy, breathing control technology is often used in radiotherapy to improve the dynamic tumor cure rate and reduce the complications of surrounding normal tissues. [0003] At present, the active breathing control system is only used to control and monitor the respiration of the radiotherapist. When the respiration range of the radiotherapist changes due to physical exertion or physical fitness in the late stage of radio...

AI Technical Summary

Problems solved by technology

[0003] At present, the active breathing control system is only used to control and monitor the respiration of the radiotherapist. When the respiration range of the radiotherapist changes due to physical exertion or physical fitness in the late stage of radiotherapy, the active breathing control system cannot notify the linear accelerator. , so that the ray beam cannot accurately irradiate the tumor target area, which affects the treatment effect
