Embodiment Construction

[0048] like figure 1 As shown, a non-invasive intracranial pressure measurement method includes the following implementation steps:

[0049] 1. The forehead bone of the patient's head is brought into contact with a controlled vibration generating device, and the device is driven by the vibration source to generate a vibration signal with a constant amplitude and frequency that has covered the patient's head;

[0050] 2. Make the occipital bone on the opposite side of the patient's frontal bone in contact with the vibration signal receiving sensor, and the signal receiving sensor receives the vibration signal transmitted through the skull and converts it into an electrical signal and transmits it to the non-invasive intracranial pressure measuring instrument;

[0051] 3. Using a non-invasive intracranial pressure measuring instrument, the vibration signal of the vibration source and the feedback signal received by the above sensors are processed by an analysis and detection alg...

Abstract

The invention discloses a non-invasive intracranial pressure measurement method and a measurement instrument implementing the method. The method comprises that a vibration signal generated in front of the head portion of a patient is transmitted to the non-invasive intracranial pressure measurement instrument; the resonance frequency of the head portion of the patient is extracted through treatment by the non-invasive intracranial pressure measurement instrument, and a measurement value of the intracranial pressure is obtained; and measurement parameters of the intracranial pressure of the patient at the moment are displayed on an upper computer software interface and a liquid crystal display. By the aid of the method, diagnoses can be conducted in real time and quickly, a high-performance processor is used for converting and analyzing signals, and results can be obtained in a few seconds after scanning is finished, so that measurement can be conducted at any time, additional influence on the patient is prevented, conditions can be monitored in real time, and changes can be grasped.

Description

technical field [0001] The invention belongs to the field of biomedicine, and particularly relates to the measurement of intracranial pressure. Background technique [0002] Intracranial pressure refers to the pressure generated by the contents of the cranial cavity against the wall of the cranial cavity, which can be expressed by the hydrostatic pressure of the cerebrospinal fluid. Medically, it is considered that the normal range of human beings is 7-18 cm water column (0.69 ~ 0.78kPa), and the intracranial pressure is 18 to 20 cm water column (1.77 ~ 1.96kPa), which are suspicious clinical symptoms. Increased intracranial pressure. [0003] Brain diseases such as brain tissue damage, infection, internal hemorrhage, hydrocephalus, etc., can cause cerebrospinal fluid accumulation and lead to a rapid increase in intracranial pressure, and increased intracranial pressure is a common cause of clinical deterioration, postoperative adverse events or death. One, it is therefore...
