The calibration component 4 includes a bracket 401 that is against the constant temperature box 1, and the bracket 401 can support a vacuum sealing cover 402. The vacuum sealing cover 402 is fixed on the bracket 401. By injecting gas into the vacuum sealing cover 402, the intracranial pressure sensor 5 can perform pressure detection, thereby facilitating its calibration. The top of the vacuum sealing cover 402 is circular. There are multiple groups of upper sealing seats 403 distributed at equal intervals. The upper sealing seat 403 can seal the top of the vacuum sealing cover 402, and a lower sealing tube 404 is installed at the bottom of the vacuum sealing cover 402 corresponding to the upper sealing seat 403. The lower sealing tube 404 can seal the bottom of the vacuum sealing cover 402. An injection tube 405 is installed in the middle of the upper sealing seat 403. Physiological saline can be injected into the lower sealing tube 404 through the injection tube 405, and the injection tube 405 extends into the lower sealing tube 404. A cranial pressure sensor 5 is installed on one side of the injection tube 405 on the upper sealing seat 403.

[0024] like Figure 2 As shown, the heating assembly 2 includes a mounting frame 201 and a heating tube 202, and the heating tube 202 is fixedly connected to the mounting frame 201, so that the heating tube 202 can be fixed in the constant temperature box 1 through the mounting frame 201, and the water is heated by the heating tube 202 to ensure constant temperature.

[0025] like Figure 1-Figure 2 As shown, the conveying component 3 includes a water inlet pipe 301 and a drain pipe 302. Both the water inlet pipe 301 and the drain pipe 302 are connected to the constant temperature box 1, so that the detection water enters the constant temperature box 1 through the water inlet pipe 301 and is discharged through the drain pipe 302 after use.

[0026] like Figure 4As shown, a platinum resistor 6 is installed on one side of the lower sealed tube 404, and the platinum resistor 6 is offset against the intracranial pressure sensor 5. The temperature can be detected synchronously by the platinum resistor 6, thereby improving the detection accuracy of the intracranial pressure sensor 5.

[0027] like Figure 1-Figure 3 As shown, an air intake assembly 7 is fixed to the top of the vacuum sealing cover 402 . The air intake assembly 7 includes a connecting seat 701 and an air intake pipe 702 . Gas is injected into the vacuum sealing cover 402 through the air intake assembly 7 .

[0028] like Figure 1-Figure 3 As shown, the connecting seat 701 is threadedly connected to the vacuum sealing cover 402, and the air inlet pipe 702 is welded to the connecting seat 701, which can be connected to the external air supply pipeline through the air inlet pipe 702, and the gas enters the vacuum sealing cover 402 through the air inlet pipe 702 and the connecting seat 701.

[0029] like Figure 2-Figure 3 As shown, a sealing cover 8 is installed at the bottom end of the lower sealing tube 404, and the sealing cover 8 is threadedly connected to the lower sealing tube 404, so that the staff can easily unscrew the sealing cover 8 to discharge the physiological saline in the lower sealing tube 404.

[0030] like Figure 1-Figure 3 As shown, the vacuum sealing cover 402 is connected to the bracket 401 by bolts, and the diameter of the bracket 401 is larger than the diameter of the vacuum sealing cover 402, so that the vacuum sealing cover 402 can be conveniently positioned above the constant temperature box 1 through the bracket 401.

[0031] Working principle of this device: When the device is used, the staff injects a certain amount of clean water into the constant temperature box 1 through the water inlet pipe 301, and heats it to a certain temperature through the heating pipe 202 between the mounting brackets 201. After the heating is completed, the clean water is always kept at a constant temperature. At this time, the staff installs the vacuum sealing cover 402 on the bracket 401, and then simultaneously installs multiple groups of intracranial pressure sensors 5 in the upper sealing seat 403 until the intracranial pressure sensors 5 and the platinum resistor 6 are offset. After the installation is completed, a certain amount of physiological saline is injected into the lower sealing tube 404 through the liquid inlet pipe. After the injection is completed, the calibration component 4 is placed in the constant temperature box. 1, and the vacuum sealing cover 402 is located above the constant temperature box 1, and then a certain gas pressure is injected into the vacuum sealing cover 402 through the air intake pipe 702 and the connecting seat 701 in the air intake assembly 7, and the pressure is detected by the intracranial pressure sensor 5. At the same time, the intracranial pressure sensor 5 is used to detect the temperature through the warm water in the constant temperature box 1, and the platinum resistor 6 can also measure the temperature, so that the detection and calibration of the intracranial pressure sensor 5 are more accurate. The vacuum sealing cover 402 is located above the constant temperature box 1 to avoid the risk of contamination of the water in the constant temperature box 1 to the new product of high-precision medical intracranial pressure sensor, and multiple groups can be measured at a time, thereby improving the measurement efficiency.
