Problems solved by technology

[0003] In the current technology, most of the intracranial pressure monitoring systems used in China are single-parameter intracranial pressure monitors or dual-parameter intracranial pressure monitors including intracranial temperature monitoring. The functions are relatively single, and it is impossible to realize multi-parameter synthesis such as cerebral perfusion pressure CPP. monitoring, for this purpose, we propose a wireless network-based multi-user intracranial pressure monitoring system to simultaneously monitor multiple parameters

Embodiment 1

[0027] see Figure 1-5 , this embodiment provides a technical solution: such as Figure 1-3 As shown, a multi-user intracranial pressure monitoring system based on wireless network, including intracranial pressure probe, signal acquisition unit, independent monitoring host unit, wireless network and multi-user monitoring software developed for the system, can realize intracranial pressure monitoring of a single patient. Accurate measurement of internal pressure and simultaneous monitoring of multiple users; intracranial pressure sensor and temperature sensor are integrated inside the intracranial pressure probe. The intracranial pressure probe also includes probe end 1, probe body 2 and interface end 3. A signal acquisition unit and a Zigbee wireless communication unit for data transmission are set. The signal acquisition unit includes an analog-to-digital converter for processing signal conversion, an MCU1 for processing data, and a storage unit for storing data. The intracra...

Embodiment 2

[0032] This embodiment differs from Embodiment 1 in that:

[0033] In this example, if Figure 5 As shown, the independent monitoring host unit includes a power management module for power supply management, a storage module for storing data, an interactive module for human-computer interaction, a serial port signal conversion module for communicating with the signal acquisition unit and an external network, The MCU2 core board module used to manage other components and the alarm module used to send out an alarm signal when an abnormality occurs.

[0034] The power management module includes a USB power supply module, an adapter power supply module and a battery power supply module, which provide multiple ways of power supply for the independent monitoring host unit. The adapter is used to supply power to the host computer during long-term bedside monitoring, and the battery is used to provide short-term power supply to the monitoring host computer when moving the patient. Th...

Embodiment 3

[0037] The multi-user monitoring software is divided into functions according to: start task, alarm task, emWin display task, serial port communication task, button processing task and power scanning task. Each task is allocated according to real-time requirements, execution cycle, importance and occupied MCU time priority.

[0038] Among them, the start task completes MCU2 hardware initialization, μC / OS-III initialization, software timer, semaphore and event flag group creation, and all other tasks are created on the μC / OS-III kernel, and the start task finally calls the OSTaskDel function to delete itself , so the start task only runs once; the alarm task uses the event flag group in μC / OS-III to indicate different types of alarm states, such as overvoltage alarm, error alarm for reading probe calibration parameters, probe use overdue alarm, low battery alarm in event Different flag bits are used in the flag group to indicate; the alarm task performs "setting" and "clearing"...

Abstract

The invention discloses a multi-user intracranial pressure monitoring system based on a wireless network. The system comprises an intracranial pressure probe, a signal acquisition unit, an independent monitoring host unit, the wireless network and multi-user monitoring software developed for the system, and an intracranial pressure sensor and a temperature sensor are integrated in the intracranial pressure probe. The signal acquisition unit comprises an analog-to-digital converter for processing signal conversion, an MCU1 for processing data and a storage unit for storing data, the intracranial pressure probe is electrically connected with the independent monitoring host unit through the wireless network and uploads the acquired data to the monitoring host, and the independent monitoring host is provided with the multi-user monitoring software and used for for managing one or more intracranial pressure probes. By monitoring the invasive arterial pressure IBP, the average arterial pressure MAP, the intracranial pressure ICP and the intracranial temperature ICT, real-time monitoring of the cerebral perfusion pressure CPP is achieved through an algorithm, dynamic monitoring of five parameters is achieved at the same time, and real-time dynamic monitoring of the parameters of multiple patients can also be achieved at the same time.

Description

technical field [0001] The invention relates to the technical field of diagnosis and treatment auxiliary equipment, in particular to a wireless network-based multi-user intracranial pressure monitoring system. Background technique [0002] Intracranial pressure ICP is an important observation index in neurosurgery clinical and scientific research. In medicine, intracranial pressure is usually represented by the pressure of cerebrospinal fluid in the ventricles. In normal people, the intracranial pressure is maintained at 5.0-15.0mmHg. It can cause sudden changes in vital signs such as headache, vomiting, fundus lesions, convulsions, peripheral nerve paralysis, disturbance of consciousness, pupillary changes, pulmonary edema, blood pressure, heart rate, and respiration. The hazards of increased intracranial pressure also include: decreased cerebral perfusion pressure CPP, brain herniation, brainstem and global cerebral ischemia, brain failure and even death. Cerebral perfus...
