Problems solved by technology

[0006] The purpose of the present invention is to provide a non-invasive intracranial pressure monitoring method for the existing technology that the measurement accuracy is easily affected by factors such as temperature and pulse, and cannot quickly reflect changes in intracranial pressure. According to near-infrared spectroscopy technology, The intracranial pressure is calculated by using the pulse wave propagation time, and the influence of the local cerebral oxygen saturation and temperature is considered, and the local cerebral oxygen saturation and temperature data are used for correction to realize the monitoring of the intracranial pressure

Embodiment 1

[0057] refer to figure 1 , a non-invasive non-invasive intracranial pressure monitoring method, comprising the following steps:

[0058] S1, collect the first head pulse wave data, temperature data and ECG data of the person under test,

[0059] According to the near-infrared spectroscopy technology, at a frequency of 40 Hz, two different wavelengths of near-infrared light are alternately emitted, the wavelengths are 760nm and 850nm respectively, and four groups of near-infrared lights refracted through the brain at different head positions are received to obtain the first A head pulse wave data p 1-760 ,p 1-850 ,p 2-760 ,p 2-850 ,p 3-760 ,p 3-850 , p 4-760 ,p 4-850 , where x in the subscript x-yyy corresponds to the near-infrared light receiving group No. 1-4, and yyy corresponds to the wavelength of the received near-infrared light, wherein the first head pulse wave data is the head pulse wave.

Abstract

The invention discloses a non-invasive intracranial pressure monitoring method and device. The monitoring method: first collect head pulse wave data, temperature data and ECG data, then use the temperature data to correct the head pulse wave, and then use the corrected head pulse wave The head pulse wave data is used to calculate the local cerebral oxygen saturation, and then the corrected head pulse wave data and ECG data are used to calculate the pulse wave propagation time, and finally the intracranial pressure value. The present invention uses the pulse wave propagation time to calculate the intracranial pressure value, and introduces local cerebral oxygen saturation and temperature data for correction, which can reduce the influence of temperature and local cerebral oxygen saturation on the monitoring accuracy of intracranial pressure, and quickly reflect the intracranial pressure. changes in internal pressure.

Description

technical field [0001] The invention relates to the technical field of intracranial pressure monitoring, in particular to a non-invasive intracranial pressure monitoring method and device. Background technique [0002] Increased intracranial pressure (ICP) is the most critical clinical sign in neurosurgery. It is not only the result of the progression of many intracranial lesions, but also the most common cause of disease progression and poor prognosis. Monitoring the value of intracranial pressure ICP provides an effective basis for diagnosing cerebral hypoperfusion caused by increased ICP, blocking brain tissue compression, displacement, and even brain herniation. [0003] At present, invasive ICP monitoring (ventricle puncture, intracranial pressure probe insertion) is used as the gold standard in clinical practice, but its disadvantages are obvious: 1. Invasive operation needs to be completed in the operating room; 2. It needs to be removed within seven days of monitorin...
