The application provides a radiotherapy breathing control threshold adaptive adjustment method based on image feedback, which comprises the following steps: before any fraction treatment, guiding a patient to perform deep inhalation breath holding, and acquiring chest three-dimensional image data of the patient through an image acquisition device; determining whether a breathing control threshold optimization condition is met based on the chest three-dimensional image data; when the breathing control threshold optimization condition is met, optimizing the breathing control threshold, and determining a new breathing control threshold for triggering radiotherapy beam output. The application uses the real lung volume calculated by three-dimensional image as a feedback variable to adaptively correct the control threshold based on inhaled gas volume in the traditional ABC system, so as to establish a closed-loop breathing control mechanism based on internal anatomical state.

A fluid dynamic valve passively allows fluid flow out of a moving stream in one flow direction and not in the reverse. This allows the collection of fluid from a single direction of an AC fluid flow. The siphoned portion of the flow has a flow rate proportional to the mainstream flow. This device can collect exhaled breath or selective entrenchment during inhale. In one orientation, it can meter aerosolized particles into an inhale breath stream for pulmonary delivery, without complicated breath timing or drug loss due to drug adsorption to the back of the throat. Alternatively, a user can breathe through the device and a proportional amount, relative to the volumetric flow rate, of each exhale can flow into an auxiliary chamber for analysis. In addition, the device has a low respiratory burden and is comfortable to use.

The present application relates to the field of medical devices, in particular to a multifunctional chronic obstructive pulmonary rehabilitation training device and a training method thereof. The present application does not require the patient to remove the breathing mask during training, can quickly recover normal ventilation, and can make the training intensity more intuitive by controlling the swing of the pointer with each breath of the patient, making it easier for the patient to adjust the training intensity. At the same time, it is convenient for patients with different recovery degrees to perform training of different intensities, and is more convenient and practical to use. The present application comprises a flow guide frame one, a connecting pipe and a flow guide frame two; the connecting pipe is fixedly connected to the flow guide frame one, the flow guide frame two is fixedly connected to the other end of the connecting pipe, and the flow guide frame one is communicated with the flow guide frame two through the connecting pipe. When the patient needs normal breathing, the breathing mask does not need to be removed, only the support frame needs to be pressed downward, so that the air outlet pipe of the flow guide pipe is communicated with the air outside, and then the patient can breathe normally through the air outlet pipe of the flow guide pipe, which is convenient to use.
