Autonomous respiration control system suitable for CT scanning

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.

Description

technical field [0001] The invention relates to a simulation training device for adjusting breathing, in particular to a spontaneous breathing control system suitable for CT scanning. Background technique [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, inhal...

[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
