Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a universal cerebral ischemic disease detection device. Background Art

[0002] Studies have reported that the incidence of postoperative cerebral hyperperfusion in patients with moyamoya disease is as high as 2.4% to 28%. In recent years, studies have found that postoperative cerebral blood flow disturbance in patients with moyamoya disease may be closely related to the cerebral blood flow reserve capacity of patients before surgery. The hyperventilation test can preliminarily determine the cerebral blood flow reserve capacity of patients with moyamoya disease before surgery. Early preliminary judgment of the cerebral vascular reserve capacity of patients with moyamoya disease is conducive to early evaluation of patients by medical staff and then taking effective preventive and therapeutic measures to prevent the occurrence of postoperative complications.

[0003] At present, the specific operation of the hyperventilation test is as follows: when the patient is admitted to the hospital, the arterial blood gas is measured in a resting state to record the pCO2 value, and then the patient is guided to do a ventilation test. After the ventilation test, the arterial blood gas is measured again to record the pCO2 value.

[0004] Before the hyperventilation test, the responsible nurse used video to record the patient's basic condition, then used a disposable paper cup to prepare a cup of boiled water, asked the patient to take a deep breath, and blew the boiled water at a respiratory rate of 24 times / minute for a total of 10 minutes. During the test, the patient was closely observed for symptoms such as headache, dizziness, limb numbness, language and limb dysfunction. If such symptoms occur, it means that the patient is hypoxic and the blowing test must be stopped immediately. However, the observation of such symptoms is not intuitive, and some patients continue to perform the blowing test when symptoms occur. If the responsible nurse fails to discover it in time, it may cause fainting, fall, or even life-threatening in severe cases. Summary of the invention

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] like Figure 1 to Figure 4 As shown, embodiment 1 is a universal cerebral ischemic disease detection device, comprising a detection device body, the detection device body comprising an air blowing tube 1; an air blowing port 11 is provided at one end of the air blowing tube 1, and an air outlet is provided at the other end of the air blowing tube 1; an airway 12 is provided in the air blowing tube 1, and the air blowing port 11 and the air outlet are connected through the airway 12; a controller 41 is provided in the detection device body, a vital capacity sensor 15 is provided in the middle of the airway 12 in the air blowing tube 1, a heart rate monitoring sensor 42, a blood oxygen saturation sensor 43 and a dioxygen partial pressure sensor 44 are provided at the grip of the air blowing tube 1, and the vital capacity sensor 15, the heart rate monitoring sensor 42, the blood oxygen saturation sensor 43 and the dioxygen partial pressure sensor 44 are electrically connected to the controller 41 respectively.

[0028] The vital capacity sensor 15 is used to detect the patient's vital capacity to determine whether the patient's vital capacity meets the standard and whether each of the patient's breaths meets the standard. The heart rate monitoring sensor 42, the blood oxygen saturation sensor 43 and the dioxygen partial pressure sensor 44 can monitor the patient's heart rate, blood oxygen saturation SPO2% and dioxygen partial pressure PaCO2 in real time during the breath-blowing process, so as to determine whether the patient has hypoxia symptoms, so as to respond quickly according to the test results and stop the patient's breath-blowing test to avoid the risk of fainting and falling caused by untimely stopping during the experiment.

[0033] The acquisition camera 16 is electrically connected to the micro-expression recognition module 17 , and the micro-expression recognition module 17 is electrically connected to the controller 41 .

[0034] The acquisition camera 16 acquires micro-expression images of the patient during the test in real time and sends them to the micro-expression recognition module 17 for processing. The micro-expression recognition module 17 compares the acquired micro-expression images with the classified micro-expression data in the expression library. The compared features include hypoxic micro-expressions such as facial blood gas, dull eyes, and pupil dilation status. Through the micro-expression recognition technology, it is identified whether the patient has hypoxic micro-expressions. When such micro-expressions appear, it indicates that the patient's brain is ischemic at this time. At this time, the patient needs to be notified to stop the air blowing experiment. Such micro-expressions are difficult to observe with the naked eye. The acquisition camera 16 and the micro-expression recognition module 17 can replace traditional naked eye judgment, which is more accurate and efficient. The hypoxia micro-expression recognition assists the hypoxia monitoring of the heart rate monitoring sensor 42, the blood oxygen saturation sensor 43 and the dioxygen partial pressure sensor 44, further improves the accuracy of hypoxia monitoring, and stops the patient's air blowing test in time.
