Problems solved by technology

[0002] CT (Computed Tomography) is an electronic computer tomography scanning instrument. It uses precisely collimated X-ray beams, γ-rays, ultrasonic waves, etc., together with highly sensitive detectors, to conduct cross-sectional scans one after another around a certain part of the human body. It is a widely used medical examination method at present. Conventional CT scanning equipment mainly includes a translational bed and a scanning area. Generally, the patient lies flat on the translational bed, and then translates into the scanning area. During the examination, it is necessary to obey the instructions of the medical staff. Guidance, such as keeping the body still, and cooperating with the inspection to perform commands such as calm breathing, breath-holding, inhalation and exhalation. If the operation is not done properly, it is easy to cause poor scanning contrast results, unclear images, and unable to diagnose the disease. It usually takes time Re-examination with money also increases the amount of CT radiation, which is likely to have adverse effects on the body
[0003] Due to the dark and semi-closed environment inside the scanning area, there is a lot of movement during the scanning process, coupled with the unfamiliarity and incomprehension of the inspection operation, it is easy for the examinee to have a sense of fear or overreaction and cannot cooperate to complete the scanning Examination; especially during the clinical scanning inspection process for the part that needs breathing coordination, the breathing action needs to cooperate with the instructions of the medical staff for execution feedback. Slower, resulting in the inability to cooperate with the instructions of medical staff, it is easy to affect the inspection results, resulting in lower scanning efficiency and inaccurate scanning results; therefore, it is necessary to strengthen the simulation training of the subjects before the inspection to reduce the psychological burden and enhance adaptability , able to cooperate with the breathing instructions of medical staff for inspection

Embodiment 1

[0037] A spontaneous breathing control system suitable for CT scanning, the control system includes a control display terminal 1, a voice prompting device 2, a wearable breathing detection device 3 and a wearable breathing force feedback device 4; the voice prompting device 2 1. The breathing detection device 3 is connected to the control display terminal 1 through wired data transmission or wireless data transmission, and the breathing force feedback device 4 forms a remote control connection with the control display terminal 1 in a wireless transmission mode through a wireless communication component, wherein:

[0038] The control display terminal 1 is used to send a preset breathing guidance instruction to the voice prompt device 2, and send a somatosensory feedback signal matching the breathing guidance instruction to the breathing force feedback device 4;

[0039] The voice prompting device 2 issues breathing guidance instructions such as exhalation, inhalation, and breath...

Embodiment 2

[0055] The difference from Embodiment 1 is that in this embodiment, the breathing force feedback device 4 is a wearable armband, and the armband is provided with contraction feedback components, and the contraction feedback components include airbags 42, micropumps 43, Exhaust valve 44, information processor 45 and controller 46; Wherein the output end of information processor 45 is electrically connected with the input end of controller 46, and the output end of controller 46 is electrically connected with micropump 43, exhaust valve 44, The micropump 43 and the exhaust valve 44 are all connected to the air bag 42 through the air hole, so as to inflate / deflate the air bag 42;

[0056] The information processor 45 receives the somatosensory feedback signal from the control display terminal 1 (control unit 12) that matches the breathing guidance instruction sent to the voice prompt device 2, and triggers the micropump 43 and the exhaust valve 44 through the controller 46. The s...

Abstract

The invention relates to simulated training equipment for adjusting respiration, in particular to an autonomous respiration control system suitable for CT scanning. The control system comprises a control display terminal, a voice prompt device, a respiration detection device and a respiratory force feedback device; the control display terminal sends a respiration guidance instruction to the voiceprompt device and send a somatosensory feedback signal to the respiratory force feedback device, and the respiratory force feedback device executes a somatosensory feedback action according to the somatosensory feedback signal; the respiration detection device is adopted to detect a pressure signal generated in the respiration process, the pressure signal is analyzed and output by the control display terminal, and respiration action which does not conform to the respiration guidance instruction is corrected, so that a subject exercises to self-adjust the respiration frequency in the simulatedtraining process; and the wearable respiration force feedback device is adopted to execute the somatosensory feedback action, the respiration rate is adjusted according to the somatosensory feedback action, and the respiratory action can be correctly adjusted after multiple times of training of a subject.
