Embodiment Construction
[0024] The technical problem to be solved by the present invention is to solve the shortcomings of traditional cerebrospinal fluid pulse pressure wave monitoring system such as invasive detection and traditional non-invasive monitoring method with low precision, and propose a non-contact cerebrospinal fluid pulse pressure wave monitoring device based on magnetic induction.
[0025] Such as figure 1 , 2 . As shown in 3, a non-contact magnetic induction cerebrospinal fluid pulse pressure wave monitoring device, the sensor unit can be directly placed at the cisterna magna under the patient's occipital bone, and can also be placed inside the pillow. The AC signal source unit, the differential amplification unit and the signal acquisition and processing unit can be fabricated on the same circuit board, so that the unit formed by the circuit board is compact and convenient to be placed beside the bed or carried around. The sensor is not in contact with the skin, absolutely safe and...
