Embodiment Construction

[0038] The intracranial pressure detection method provided in this embodiment is composed of an in vivo part and an in vitro part that are completely independent on hardware, such as figure 1 shown. The extracorporeal part of the method can control the intracranial part to automatically and continuously monitor the intracranial pressure at a set time interval. The in vitro part can display and record the measurement results in real time; the measurement result data can also be transmitted to other devices through the output interface for display, analysis and recording.

[0039] Such as figure 2 As shown, the external part includes: power supply, voltage regulator chip (MAX8881) circuit, microcontroller PIC, radio frequency circuit chip (MLX90121) circuit, antenna coil, display and control interface, data memory, serial port RS232, level conversion chip (MAX3226) circuit , pressure sensor, instrumentation amplifier (MAX4194) circuit, reference voltage chip (MAX6120) circuit...

Abstract

The invention relates to an implantable wireless intracranial pressure automatic monitoring method. In the monitoring method, a monitoring system which is formed by an internal part and an external part completely independently of each other is used. When in use, the two parts are communicated with each other through radio frequency so as to fulfill the aim of monitoring intracranial pressure automatically. The method comprises the following steps that: (1) the external part provides energy for the internal part through radio electromagnetic waves; (2) the internal part receives the energy and starts to operate; (3) the external part sends a command to the internal part through electromagnetic waves; (4) after receiving the command, the internal part acquires intracranial pressure data, encodes the intracranial pressure data and transmits the encoded intracranial pressure data to the external part; and (5) the external part receives the data, decodes and acquires the intracranial pressure data after processing. The automatic monitoring method of the invention has the characteristics of more convenience, rapidness, accuracy, safety, reliability and effectiveness, less infection and high applicability.

Description

technical field [0001] The invention relates to an intracranial pressure measurement system method, in particular to an implanted wireless intracranial pressure automatic monitoring method. Background technique [0002] Increased ICP (intracra-nial pressure (ICP) (intracranial pressure)) is a reflection of intracranial diseases or secondary intracranial lesions, if the increase in ICP is not detected in time and effective treatment measures are taken, it may lead to serious consequences , even life-threatening. In clinical work, it is difficult to explain the actual level of ICP simply by observing nervous system symptoms or CT and MRI imaging data to judge whether the ICP is increased. Therefore, continuous ICP monitoring is used as an "early alarm system", which is conducive to early detection and timely diagnosis. Deal with increased ICP and intracranial diseases, and improve curative effect. According to the objective data of ICP, it can guide clinical treatment and pr...
