Induced respiration controller and implementation method thereof

Abstract

The invention discloses an induced respiration controller and mainly solves the problems that the prior respiration control technology is low in efficiency, inconvenient to implement and is high in cost. The induced respiration controller comprises an eyeball protection unit, a breathing lamp unit, a control unit and an electric power unit, wherein the eyeball protection unit is used for protecting eyeballs of a patient from being injured by radiation; the breathing lamp unit is arranged in the eyeball protection unit and is used for generating gradient light ray, enabling the eyeballs of the patient to sense the light and inducing the patient to regulate the breathing frequency and extent according to the light flicker frequency; the control unit is used for controlling and regulating the flicker frequency of the breathing lamp; and the electric power unit is used for supplying electric power to the breathing lamp and the control unit. Based on the structure, the invention also discloses an implementation method of the induced respiration controller. According to the induced respiration controller, the breathing speed and extent are controlled through lamplight, the speed of lamplight is adjusted in a visualized manner, the patient is enabled to adapt to the regulation more easily, the difficulty of respiratory training in clinical context is reduced, and the respiratory control efficiency is improved. Therefore, the induced respiration controller and the implementation method thereof are suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a breathing induction controller for auxiliary radiotherapy and a realization method thereof. Background technique [0002] Radiation therapy is one of the three major means of treating tumors. Its theoretical basis is that tumor cells are more sensitive to radiation than normal cells. During radiation therapy, radiation can also damage normal cells while killing tumor cells. Different types of normal cells have different sensitivities to rays. For example, lens cells are particularly sensitive to rays and are easily damaged by rays; and the lens is an important part of the refractive system of the eyeball, and the only refractive lens with the ability to adjust. Therefore, reducing the ray dose received by the lens is of great significance to protect the patient's vision. [0003] During radiotherapy, due to the influence of chest and abdomen respiratory movement, tum...

AI Technical Summary

Problems solved by technology

Irregular breathing leads to irregular tumor movement, which makes it difficult to accurately locate the target area of ​​radiation therapy, which not only reduces the therapeutic effect, may lead to tumor recurrence, but also easily expands the irradiation of radiation to normal tissues of patients, resulting in normal cell damage and necrosis. , leading to radiotherapy complications

Aiming at the above-mentioned defects, the usual way is to adopt breathing control technology to cooperate with treatment for patients; in the prior art, commonly used breathing control technology has ABC active breathing control technology and RPM real-time position management breathing synchronization tracking control technology, the former is to combine breathing action with Synchronization of radiation therapy requires the patient to hold a breathing sensor in the mouth and perform several adaptive trainings. This method is inefficient and the effect of breathing regulation is not significant, and the tracking accuracy of the latter cannot fully adapt to the changes of the tumor, and it is expensive. It is difficult to popularize and popularize, and the practical value is not high

[0004] Further, there are also technical means to achieve respiratory control through other means, such as: a radiation therapy respiratory gating indication method with an application date of 2011.11.24, which has positive significance for radiotherapy, but it only considers The eyes are sensitive to light, and the doctor presets the light, and the patient controls the breathing through the preset light. The patient is relatively passive in the control process, and the control effect is not good, and the practicability is not strong. The combination of eye protection technology and breathing control technology has poor integration of equipment and single function, which is very troublesome in practical application
