[0052] In one embodiment, reference Figure 2The extracerebral drainage management device also includes a first liquid flow switch 400 with a timing function. When the box body 100 includes an upper half 120 and a lower half 130, the first liquid flow switch 400 is installed in the first installation cavity 111, and the first liquid flow switch 400 is used to control the circulation of the second catheter 740. The first liquid flow switch 400 includes a catheter channel 420 arranged on the cavity wall of the first installation cavity 111, and the catheter channel 420 is used for installing the second catheter 740, wherein an extrusion block 430 is arranged in the catheter channel 420, and the extrusion block 430 and the channel wall of the catheter channel 420 can clamp the second catheter 740. Further, the first liquid flow switch 400 also includes a second driving member 410, and the second driving member 410 is used to drive the extrusion block 430 to move toward the second catheter 740, and at the same time cooperate with the channel wall of the catheter channel 420 to squeeze the second catheter 740. When the second catheter 740 is pressurized, the liquid flow rate in the second catheter 740 will change, and the liquid flow rate in the second catheter 740 will also change according to the degree of pressure on the second catheter 740. Furthermore, in order to further increase the pressure exerted by the extrusion block 430 on the second conduit 740, a ridge is provided on the side of the extrusion block 430 facing the second conduit 740, and the pressure exerted by the extrusion block 430 on the second conduit 740 is increased by reducing the area of ​​the ridge on the second conduit 740, so that the extrusion block 430 can better control the flow rate of the liquid in the second conduit 740. It should be noted that the second conduit 740 is usually made of soft rubber material, which will be deformed after being squeezed. When the squeezing force gradually disappears, the second conduit 740 will restore the deformation. Further, in this embodiment, the second driving member 410 is configured as a steering gear, and the steering gear has a timing function. It should be noted that the steering gear in this application does not have a timing function, and the timing function can be realized by programming, wherein the programming can be operated by a plc or a single-chip microcomputer. The rotating shaft of the servo is connected to the extrusion block 430 through a connecting rod 440. At this time, the connecting rod and the rotating shaft of the servo can be keyed or fixedly connected. In this way, when the rotating shaft of the servo rotates, the connecting rod can be driven to swing. Further, the connecting rod is rotationally connected to the extrusion block 430. In order to improve the use effect of the extrusion block 430, a dovetail groove is provided on the extrusion block 430, and a sliding part is provided in the dovetail groove.

Further, the pressure sensor is installed in the human brain, and the pressure sensor is electrically connected to the control panel 500, and can feed back the pressure data of the human brain to the control panel 500. When the pressure sensor detects that the intracranial pressure value is too high, the control panel 500 operates the first driving member 310, and the first driving member 310 drives the drainage bottle 710 to move downward to adjust the drainage speed, allowing more cerebrospinal fluid to be discharged, and helping to reduce the intracranial pressure. When the intracranial pressure is at a suitable value, the control panel 500 controls the operation of the first driving member 310, and the first driving member 310 drives the drainage bottle 710 to move upward. Further, in this embodiment, the control panel 500 is also provided with a data storage module and a data analysis and processing module, wherein the data analysis and processing module enables the control panel 500 to judge the received pressure value. Further, in some embodiments, the control panel 500 can also summarize the intracranial pressure data according to the data storage module and the data analysis and processing module, and issue a numerical diagram of intracranial pressure changes, so that doctors can understand the changes in intracranial pressure. It should be noted that the position of the drainage bottle 710 is adjusted by a pressure sensor, wherein the distance of a single adjustment of the position of the drainage bottle 710 is 3cm-5cm. Further, the intracranial pressure is monitored by a pressure sensor. When abnormal intracranial pressure (significantly increased and with acute risks, such as brain hernia) is detected, the control system can automatically adjust the position of the drainage bottle 710 by the height lifting component at the first time, so that the drainage bottle 710 moves downward, and the cerebrospinal fluid outflow is increased without waiting for the operation instructions of the control panel 500. This can avoid the problem that the doctor fails to arrive at the ward in the first time, resulting in a slow adjustment of the drainage bottle 710 and panic when the drainage bottle 710 is adjusted.

[0057] Furthermore, in some embodiments, different from the above-mentioned monitoring of intracranial pressure to adjust the position of the drainage bottle 710, the integrated extracerebral drainage device in this embodiment also includes a flow sensor (not shown), which is used to monitor the drainage speed, wherein the flow sensor is electrically connected to the control panel, specifically, the flow sensor is electrically connected to the control system in the control panel 500, and the flow sensor can be installed at the outlet of the second catheter 740, that is, the second catheter 740 is close to one end of the drainage bottle 710. When the flow sensor detects that the drainage flow rate is too fast, the drainage bottle 710 is moved upward, so as to prevent excessive drainage from causing low intracranial pressure or other complications.

[0058] It should be noted that when the extracerebral drainage management device further includes a pressure sensor or a flow sensor, the extracerebral drainage management device further includes an alarm module, wherein the alarm module is arranged at the medical station and is wirelessly connected to the control system in the control panel. When abnormal drainage is detected, the alarm module sends an alarm signal to promptly remind the medical staff at the medical station. When the medical staff receives the signal, they go to the patient's ward to observe the patient's condition, and then adjust the position of the drainage bottle 710 through the control panel 500. In some embodiments, the alarm module can also be a buzzer arranged on the box 100. When the alarm module alarms, the buzzer sounds, and the patient's accompanying person can call the medical staff at the medical station through the caller in the ward.

[0059] Furthermore, in some embodiments, a liquid level sensor is provided in the liquid storage bottle 720, and the liquid level sensor is electrically connected to the control panel 500. The liquid level sensor is used to monitor the liquid level in the liquid storage bottle 720. When the liquid level in the liquid storage bottle 720 is too high, the liquid level sensor feeds back a signal to the control panel 500. After receiving the signal, the control panel 500 issues an alarm through the alarm module. At this time, the medical staff goes to the patient's ward to observe the patient's condition according to the alarm. The liquid level sensor is arranged away from one end of the first catheter 730 located in the liquid storage bottle 720.

[0060] Further, in some embodiments, reference Figure 1 , Figure 2, the extracerebral drainage management device also includes a detection module 600 arranged outside the box 100. The detection module 600 is used to obtain the vertical height between the detection module 600 and the human ear, wherein the detection module 600 can be a structured light camera 610 system, wherein when the box 100 is installed, the structured light camera 610 needs to be set toward the human brain, and the structured light camera 610 system transmits a specific light pattern, such as stripes or dots, to the patient's head. The camera captures the reflection of the transmission pattern on the human brain and ear, and uses the practical image processing algorithm to identify the key feature points of the ear. According to the deformation of the projected pattern, combined with the principle of triangulation, each key three-dimensional coordinate of the ear surface is calculated, and the vertical height information is extracted from the three-dimensional coordinates, that is, the vertical distance of the human ear relative to the structured camera. At this time, the detection module 600 can obtain the vertical height between the detection module 600 and the human ear. It should be noted that the detection module 600 is set at the midpoint of the guide rail 311, that is, the detection module 600 obtains the vertical height between the detection module 600 and the human ear, that is, the vertical height between the midpoint of the guide rail 311 and the human ear. Further, in some embodiments, the initial position of the slider 312 and the end of the second catheter 740 located at the drainage bottle 710 are located at the midpoint of the guide rail 311. At this time, when the device is in the initial use and the second catheter 740 has not yet been drained, the box 100 is installed on the infusion stand, and the vertical height of the midpoint of the guide rail 311 from the human ear is obtained by the detection module 600. The first driving member 310 drives the slider 312 to move according to the vertical height feedback, and adjusts the distance between the end of the second catheter 740 located at the drainage bottle 710 and the human ear, so that the distance meets the drainage requirements. For example, when the detection module 600 detects that the distance between the midpoint of the guide rail 311 and the human ear is 8cm, the first driving member 310 drives the slider 312 to move 2cm-12cm upward with the midpoint of the guide rail 311 as the origin, so that the distance between the end of the second catheter 740 located at the drainage bottle 710 and the human ear is 10cm-20cm, which meets the drainage height requirements. Furthermore, in order to achieve precise movement of the slider 312 on the guide rail 311, the drive motor 313 in the first drive member 310 can adopt a servo motor, wherein the servo motor cooperates with an encoder to achieve precise movement of the slider 312 on the guide rail 311, wherein the encoder can be a core encoder or a rotary encoder.
