The system also comprises an earphone which is worn during examination and plays soothing music or sleep-aiding sound waves while calming, so that the influence of noise of a magnetic resonance instrument or a CT (computed tomography) machine on the heart of the tested body is reduced, the adverse emotion of the tested body caused by adverse reactions of sedatives can be appealed, the earphone can be controlled by a control console, and the volume of the music provided by the earphone and the size of the sound waves are adjusted through data fed back by a vital sign monitor.
The working process is as follows:
before magnetic resonance or CT examination, an anesthesia and sedation medicine is injected into a subject, then the subject is placed on a magnetic resonance/CT platform, the subject is fixed at a proper examination position by a fixing band, and a noninvasive breathing device, a micro-pump and a vital sign detector are arranged beside the subject. The placement positions of the noninvasive breathing device, the micropump and the vital sign detector cannot shield the sight of a detector for observing a detected body.
During the magnetic resonance or CT examination, vital signs such as the breathing of the subject fed back from the console are monitored. When the monitoring device detects that the oxygen saturation of the subject is lower than 95% or that the oxygen saturation is not steady and tends to decrease, the control device sends a signal to the assisted respiration device so that the oxygen supply amount is increased to the subject. The relation between the tidal volume of oxygen output by the auxiliary breathing device and the weight of the detected body is 6-8ml/kg, and the relation between the tidal volume of oxygen and the weight of the detected body is limited to 6-8ml/kg, so that the gas inhaled into the body of the detected body is sufficiently humid, normal breathing cannot be influenced due to overhigh tidal volume, and the stimulation of dry gas to respiratory mucosa is reduced. Observing the reaction of the object through a window of a control room, and additionally injecting anesthetic into the object when body movement occurs or the examination time exceeds the effective time of the sedative; when electrocardiogram data or non-invasive blood pressure detected by the vital sign monitoring device is abnormal, emergency drugs such as booster drugs are injected into the detected object through the other channel of the micro pump, the condition that the electrocardiogram data or the non-invasive blood pressure is abnormal is the condition that the heart rate and the blood pressure of the detected object are reduced by 20% of the basic value or even continuously reduced, and the basic value is the data measured before the object is calmed. In addition, if the subject is a child, the patient may be placed in the oropharyngeal airway or the nasopharyngeal airway in order to prevent respiratory obstruction such as glossoptosis.
The auxiliary breathing device, the auxiliary medication device and the vital sign monitoring device in the embodiment of the invention can be changed into manual control, and when the condition of the detected body is complex and needs to be adjusted through the experience of detection personnel in time, the control mode of the control device can be adjusted and changed into manual control. The console is provided with a display device, and the oxygen supply amount and the medicine supply are manually adjusted through the vital sign data displayed by the display device.
In addition, the examination and sedation monitoring system provided by the invention not only can be used in magnetic resonance or CT examination, but also can be used in interventional operations such as myocardial infarction or cerebral infarction and the like, and can be used for outdoor control and vital sign monitoring in the operation process.
