Embodiment 1

[0036] see figure 1 , figure 2 as well as image 3 , the present embodiment provides a method for monitoring intracranial pressure, which monitors intracranial pressure through an intracranial pressure detection device. Wherein, the intracranial pressure detection device includes a pressure measuring probe 1, and may also include a connector 5, a sensor interface and a host. The intracranial pressure detection device is a tool used in the monitoring method, and it needs to cooperate with simple operations when it is used. The monitoring method of this embodiment is different from the existing intracranial pressure monitoring method. This method can be carried out in conjunction with surgery. Not only will it not affect the drainage of cerebrospinal fluid, but it can also be used as an important monitoring method for drainage to ensure the safety of drainage. a series of problems that arise.

[0037]The pressure measuring probe 1 is provided with a plurality of detection h...

Embodiment 2

[0055] This embodiment provides a method for monitoring intracranial pressure, which adds the following steps on the basis of Embodiment 1.

[0056] Determine if intracranial pressure exceeds a pressure threshold.

[0057] When the intracranial pressure exceeds the pressure threshold, an excessive pressure alarm signal is issued and the cerebrospinal fluid is released through the drainage tube, and the intracranial pressure is continuously measured.

[0058] Therefore, in this embodiment, it is also judged whether the intracranial pressure exceeds the pressure threshold, and if so, an alarm signal is issued and the cerebrospinal fluid is released through the drainage tube, which can avoid excessive intracranial pressure, and can detect intracranial pressure while performing Drainage operation, so as to ensure the continuous and effective monitoring of intracranial pressure.

Embodiment 3

[0060] This embodiment provides a method for monitoring intracranial pressure, which adds the following steps on the basis of Embodiment 1.

[0061] Before placing the pressure measuring probe 1, fill the cavity with a conductive medium to make the film bulge, and record the detection value of the pressure sensor;

[0062] Set the pressure value displayed on the host at this time to zero or as a baseline, and then put the pressure measuring probe 1 in.

[0063] In this way, this embodiment can ensure that the membrane can be slightly bulged in the initial state, so that when the pressure measuring probe 1 is placed in the cerebrospinal fluid, it will be pressed by the cerebrospinal fluid, thereby squeezing the conductive medium and changing the detection value of the pressure sensor. That is, increase, and the data displayed on the host computer will also increase, so that the increased value can reflect the situation of intracranial pressure.

Abstract

The invention discloses an intracranial pressure monitoring method and device. The monitoring method comprises the steps that a pressure sensor is connected with a pressure measuring probe, and a pressure transmission path from a thin film to the pressure sensor is formed; the pressure measuring probe is implanted into the ventricle of a patient, and intracranial pressure is conducted to the thinfilm of the pressure measuring probe by using cerebrospinal fluid in the ventricle; the cerebrospinal fluid pressure change is converted into a grating signal through the pressure sensor; the gratingsignal is transmitted to a photoelectric analysis module through an optical fiber, so that the photoelectric analysis module converts the grating signal into an electric signal; and digital-to-analogue conversion is carried out on the electric signal to obtain a pressure waveform representing the intracranial pressure and the pressure waveform is displayed. Operation such as drainage can be carried out while monitoring is carried out, due to the fact that the size of the pressure measuring probe is relatively small, and meanwhile an optical fiber sensor and the corresponding optical fiber arerelatively thin, drilling insertion of the pressure measuring probe can be achieved, detection is carried out according to the medium conduction principle, the principle of a communicating vessel is not needed, operation is easy, and cerebrospinal fluid drainage can be carried out synchronously.

Description

technical field [0001] The invention relates to a monitoring method in the technical field of clinical monitoring, in particular to an intracranial pressure monitoring method, and also relates to an intracranial pressure monitoring device. Background technique [0002] Intracranial pressure (ICP) refers to the pressure of cranial contents (brain tissue, cerebrospinal fluid, blood) on the wall of the cranial cavity. Increased intracranial pressure refers to intracranial pressure continued to exceed 15mmHg (20cmH2O or 2.00kPa). A variety of severe neurological diseases, such as craniocerebral trauma, cerebrovascular disease, encephalitis, meningitis, venous sinus thrombosis, brain tumors, etc., are often accompanied by increased intracranial pressure to varying degrees. Increased intracranial pressure can cause disturbance of consciousness in patients, and brain herniation in severe cases, which can be life-threatening in a short time. Intracranial pressure monitoring has im...
