Description

Technical Field

[0001] This invention relates to the field of medical monitoring equipment technology, and in particular to a CT-guided particle implantation bidirectional monitoring system and method. Background Technology

[0002] CT-guided particle implantation surgery is typically performed in a CT room with radiation protection requirements. During the procedure, the puncture path is determined based on the CT scan results, the implantation position is corrected, and the particle distribution is observed. To ensure safety, patients are usually connected to monitoring equipment during the procedure to continuously monitor vital signs such as heart rate, blood oxygen saturation, and blood pressure. This type of surgery has a significant spatial switching characteristic: during the CT scan phase, medical staff typically observe the patient and the scan from the control room side; during the puncture, positioning, and particle implantation phases, medical staff need to enter the CT room for close-range operation.

[0003] Most existing monitoring equipment uses a unidirectional display structure, with the screen typically facing a fixed observation direction. In CT-guided particle implantation surgery, if the monitoring equipment screen faces into the CT room, medical staff in the control room cannot directly observe vital signs during the scanning phase; if the screen faces into the control room, medical staff operating inside the CT room cannot easily observe the monitoring data. To accommodate the observation needs at different stages, the placement or orientation of the monitoring equipment may need to be manually adjusted in clinical use, affecting the continuity of the surgical procedure.

[0004] In addition, CT equipment may be subject to electromagnetic interference during operation. When monitoring data needs to be transmitted to multiple displays or displayed over long distances, the lack of anti-interference transmission design for the CT working environment may affect the data transmission and display stability of vital signs.

[0005] To address this, a CT-guided particle implantation bidirectional monitoring system and method are proposed. Summary of the Invention

[0006] In view of this, the present invention provides a CT-guided particle implantation bidirectional monitoring system and method to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0007] The technical solution of the present invention is implemented as follows: a CT-guided particle implantation bidirectional monitoring system, comprising a vital signs monitoring host, a first display unit, a second display unit, a display synchronization control module, a control module, an anti-interference communication module, and a risk warning module.

[0008] The vital signs monitoring host is used to collect the patient's vital signs data during CT-guided particle implantation and send the vital signs data to the display synchronization control module. The vital signs data includes at least one of heart rate, electrocardiogram (ECG) signal, blood oxygen saturation, and blood pressure, and may further include respiratory rate, body temperature, etc., depending on the configuration of the monitoring equipment. The vital signs monitoring host can be a multi-parameter monitoring device with ECG, blood oxygen, and blood pressure acquisition functions, or it can be a medical monitoring host with a data output interface.

[0009] The first display unit is positioned facing the interior of the CT scan room and is used to display the vital signs data. The first display unit is primarily for observation by medical personnel inside the CT scan room performing punctures, positioning, particle implantation, or other auxiliary procedures. The second display unit is positioned facing the control room outside the CT scan room and is used to display the vital signs data. The second display unit is primarily for observation of the patient's vital signs by medical personnel in the control room during the CT scan phase.

[0010] The display synchronization control module is connected to the vital signs monitoring host, the first display unit, and the second display unit, respectively, and is used to synchronously output the vital signs data to the first display unit and the second display unit. Through the display synchronization control module, the first display unit and the second display unit can simultaneously display the vital signs information of the same patient, enabling medical staff to obtain patient monitoring data regardless of whether they are inside the CT room or in the control room.

[0011] The control module is connected to the display synchronization control module and is used to acquire at least one surgical procedure status, either the CT scan status or the particle implantation operation status, and control the display modes of the first and second display units according to the surgical procedure status. Specifically, when the control module determines that the current state is a CT scan, it controls the second display unit to enter an external priority display mode; when the control module determines that the current state is a particle implantation operation, it controls the first display unit to enter an internal priority display mode. Neither the external nor internal priority display modes indicate that the other display unit stops displaying; rather, they allow the display unit corresponding to the current primary observation space to display vital signs data or warning information in a more prominent manner.

[0012] The anti-interference communication module is connected between at least two of the vital signs monitoring host, the display synchronization control module, the first display unit, and the second display unit, and is used to transmit the vital signs data in an anti-electromagnetic interference manner. The risk warning module is connected to the vital signs monitoring host and the display synchronization control module, and is used to generate an abnormal warning signal based on the vital signs data, and to cause the first display unit and the second display unit to synchronously output warning prompts through the display synchronization control module.

[0013] Furthermore, the first display unit and the second display unit are respectively located on opposite sides of the main body of the monitoring equipment, or are respectively mounted by brackets to form a display structure facing away from each other, so that the display surface of the first display unit faces the interior of the CT room, and the display surface of the second display unit faces the observation direction of the control room. The first display unit and the second display unit can adopt a fixed installation structure or an adjustable bracket structure, so as to adjust the installation according to the layout of the CT room, the position of the observation window, or the observation angle of the control room.

[0014] Furthermore, the display synchronization control module includes a data receiving unit, a display data conversion unit, and a synchronization output unit. The data receiving unit receives vital sign data output by the vital sign monitoring host; the display data conversion unit converts the vital sign data into display data adapted to the first and second display units; and the synchronization output unit outputs the display data to the first and second display units respectively. Thus, vital sign data can be synchronously presented on both display units in the form of parameters, waveforms, trend graphs, or alarm information.

[0015] Furthermore, the control module is used to determine the surgical procedure status based on at least one of the following: CT equipment operating signal, CT protective door opening / closing signal, manual operation input signal, and preset surgical stage signal. Specifically, when the control module receives a CT protective door closing signal or a CT equipment scanning operating signal, it determines that it is currently in a CT scanning state and controls the second display unit to enter an external priority display mode; when the control module receives a CT protective door opening signal or a particle implantation operation input signal, it determines that it is currently in a particle implantation operation state and controls the first display unit to enter an internal priority display mode.

[0016] Furthermore, the external priority display mode includes at least one of increasing the display brightness of the second display unit, increasing the display font size of vital sign data in the second display unit, and increasing the display priority of warning information in the second display unit. The internal priority display mode includes at least one of increasing the display brightness of the first display unit, increasing the display font size of vital sign data in the first display unit, and increasing the display priority of warning information in the first display unit. In this way, both the observers in the control room during the CT scan phase and the operators in the machine room during the particle implantation operation phase can obtain a display effect more suited to their observation positions.

[0017] Furthermore, the anti-interference communication module includes at least one of a shielded cable, an optical fiber communication unit, a filtering circuit, an isolation circuit, and a grounding shielding structure. The anti-interference communication module is used for electromagnetic interference-resistant transmission of vital sign data in a CT scan environment, wherein the data transmission error rate is no higher than 10. -6 The electromagnetic interference suppression frequency range is 10kHz to 1GHz; the anti-interference strength of the communication signal is not less than 10V / m; the signal transmission delay is not higher than 200ms; and the shielding effectiveness of the grounding shielding structure is not less than 40dB to ensure stable transmission and synchronous display of vital sign data during CT scanning. The above parameters can be tested and confirmed according to actual product testing conditions, medical equipment communication interface conditions, and the electromagnetic environment of the CT room.

[0018] Furthermore, the risk warning module is used to compare the vital sign data with preset abnormal thresholds, and generate the abnormal warning signal when at least one of heart rate, blood oxygen saturation, and blood pressure exceeds the corresponding preset abnormal threshold. The preset abnormal threshold can be set by medical staff according to the individual patient's condition, or the default threshold of the monitoring device can be used.

[0019] Furthermore, the first and second display units synchronously output warning prompts upon receiving the abnormal warning signal. The warning prompts from the first display unit include at least one of sound prompts, light prompts, flashing displays, and color-changing displays, while the warning prompts from the second display unit include at least one of highlight displays, flashing displays, color-changing displays, and magnified displays. Through synchronous prompts from different display terminals, medical personnel located both inside the CT room and in the control room can promptly obtain abnormal information.

[0020] Furthermore, the control module is also connected to a human-machine interface input unit, which includes at least one of a foot switch, physical buttons, a touch input unit, and a voice input unit. This unit receives display mode switching commands and, based on the commands, controls the first or second display unit to enter the corresponding priority display mode. This human-machine interface input unit can supplement the automatic identification of the surgical procedure status, enabling medical personnel to manually adjust the display mode according to the actual surgical progress.

[0021] Furthermore, after detecting the switch between the CT scan state and the particle implantation operation state, the control module completes the priority display mode switch between the first display unit and the second display unit within 0.1 to 2 seconds. By limiting the mode switching time, the display focus can respond more quickly to changes in the space where medical staff are located, reducing display lag between the scanning stage and the operation stage.

[0022] Furthermore, upon receiving a CT protective door closing signal, the control module controls the second display unit to enter the external priority display mode within 500ms; upon receiving a CT protective door opening signal, it controls the first display unit to enter the internal priority display mode within 500ms. Thus, the system can use the opening and closing status of the CT protective door as the trigger for switching operating spaces, ensuring that the display mode switching matches the actual flow of medical staff entering and exiting the CT room.

[0023] Furthermore, upon detecting abnormal vital signs, the risk warning module triggers the first and second display units to synchronously output an abnormality warning within 100ms to 1s. By limiting the abnormality warning trigger time, the two display terminals can output alarm information more quickly, reducing the lag in abnormality status prompts.

[0024] Furthermore, the control module includes a microprocessor, a memory, a communication interface, and a status recognition interface. The memory stores a display mode switching program, which the microprocessor executes to control the display modes of the first and second display units according to the surgical procedure status. The communication interface receives vital sign data or display control data, and the status recognition interface receives CT equipment operating signals, CT protective door opening / closing signals, manual operation input signals, or preset surgical stage signals.

[0025] Furthermore, the system also includes a local cache module, used to cache vital sign data from the most recent 30 seconds to 5 minutes when the anti-interference communication module experiences a communication anomaly, and to provide this data for display by the first and second display units. The local cache module can be located within the display synchronization control module or as an independent storage unit. When the anti-interference communication module experiences a short-term communication anomaly, the local cache module can retain vital sign data from the most recent period, allowing the display units to display historical data, resume display, or assist in determining changes in the patient's condition during the communication anomaly.

[0026] The present invention also provides a CT-guided particle implantation bidirectional monitoring method, applied to the above-mentioned CT-guided particle implantation bidirectional monitoring system, the method comprising the following steps: Collect vital sign data of patients during CT-guided particle implantation; The vital signs data are simultaneously output to the first display unit facing the interior of the CT room and the second display unit facing the observation direction of the control room; Acquire at least one surgical procedure status, either the CT scan status or the particle implantation operation status; When it is determined that the current state is a CT scan, the second display unit is controlled to enter the external priority display mode; When it is determined that the current state is in particle implantation operation, the first display unit is controlled to enter the internal priority display mode. The vital signs data are transmitted in an anti-electromagnetic interference manner through an anti-interference communication module. Based on the vital signs data, determine whether the patient is in an abnormal state, and when the patient is determined to be in an abnormal state, cause the first display unit and the second display unit to output warning prompts simultaneously.

[0027] Furthermore, acquiring the surgical procedure status includes acquiring at least one of the following: CT equipment operating signal, CT protective door opening / closing signal, manual operation input signal, and preset surgical stage signal. Specifically, upon acquiring a CT protective door closing signal or a CT equipment scanning operating signal, it is determined that the current state is CT scanning, and the second display unit is controlled to enter external priority display mode; upon acquiring a CT protective door opening signal or a particle implantation operation input signal, it is determined that the current state is particle implantation operation, and the first display unit is controlled to enter internal priority display mode. When at least one of the vital signs data—heart rate, blood oxygen saturation, and blood pressure—exceeds a corresponding preset abnormal threshold, an abnormal warning signal is generated, and the first and second display units simultaneously output a warning prompt.

[0028] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. This invention sets up a first display unit facing the inside of the CT room and a second display unit facing the observation direction of the control room, and outputs vital sign data to the two display units synchronously through a display synchronization control module. This allows medical staff to observe the patient's vital sign data whether they are inside the CT room or in the control room, reducing the inconvenience caused by a single display direction.

[0029] Second, the present invention obtains the CT scan status and particle implantation operation status through the control module, and controls the second display unit to enter the external priority display mode or controls the first display unit to enter the internal priority display mode according to the surgical procedure status, so that the display focus can match the current surgical stage and the space where the medical staff are located.

[0030] Third, this invention uses an anti-interference communication module to transmit vital sign data against electromagnetic interference, and uses a risk warning module to enable the first and second display units to output warning prompts synchronously, which helps to improve the stability of monitoring data transmission and abnormal prompts in the CT working environment.

[0031] The above overview is for illustrative purposes only and is not intended to be limiting in any way.

[0035] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] like Figures 1 to 5 As shown, this embodiment of the invention provides a CT-guided particle implantation bidirectional monitoring system, including a vital signs monitoring host 1, a first display unit 2, a second display unit 3, a display synchronization control module 4, a control module 5, an anti-interference communication module 6, and a risk warning module 7. This system is suitable for CT-guided radioactive particle implantation surgery, especially for scenarios where medical staff need to switch observation positions between the CT room and the control room during surgery.

[0038] The vital signs monitoring host 1 is used to connect to the patient and collect the patient's vital signs data during CT-guided particle implantation. Vital signs data may include one or more of the following: electrocardiogram (ECG) signal, heart rate, blood oxygen saturation, and blood pressure. Depending on the configuration of the monitoring equipment, it may also include data such as respiratory rate and body temperature. Specifically, the vital signs monitoring host 1 can collect the patient's ECG signal via ECG leads, collect the patient's blood oxygen saturation via a pulse oximeter probe, and collect the patient's blood pressure data via a non-invasive blood pressure cuff. After processing by the vital signs monitoring host 1, the above vital signs data is sent to the display synchronization control module 4.

[0039] The first display unit 2 is positioned facing the interior of the CT scan room and is used to display vital sign data. The display surface of the first display unit 2 faces the direction of medical personnel performing punctures, particle implantations, or other auxiliary procedures within the CT scan room, allowing them to monitor the patient's vital signs during the procedure. The second display unit 3 is positioned facing the control room outside the CT scan room and is used to display vital sign data. The display surface of the second display unit 3 is positioned so that medical personnel in the control room can see it through an observation window, leaded glass, or monitor, allowing them to monitor the patient's vital signs during the CT scan phase.

[0040] The first display unit 2 and the second display unit 3 can be respectively located on opposite sides of the main body of the monitoring equipment, or they can be mounted on brackets to form a display structure facing away from each other. The brackets can be fixed brackets or adapter brackets with angle adjustment functions, so as to adjust the display direction according to the layout of the CT room, the position of the observation window, and the placement of the monitoring equipment. The first display unit 2 and the second display unit 3 can be LCD screens, touch screens, medical display terminals, or other display devices capable of displaying vital sign data.

[0041] The display synchronization control module 4 is connected to the vital signs monitoring host 1, the first display unit 2, and the second display unit 3, respectively. It receives vital signs data output by the vital signs monitoring host 1 and synchronously outputs the vital signs data to the first display unit 2 and the second display unit 3. Through the display synchronization control module 4, the first display unit 2 and the second display unit 3 can simultaneously display the vital signs information of the same patient, avoiding the problem of visibility from only one direction while observation from the other is inconvenient.

[0042] In this embodiment, the display synchronization control module 4 may include a data receiving unit, a display data conversion unit, and a synchronization output unit. The data receiving unit receives vital sign data output by the vital sign monitoring host 1; the display data conversion unit converts parameters such as heart rate, blood oxygen saturation, and blood pressure into a digital display interface, waveform display interface, parameter list display interface, or trend display interface; the synchronization output unit outputs the converted display data to the first display unit 2 and the second display unit 3 respectively. The display content of the first display unit 2 and the second display unit 3 can be completely identical, or, based on synchronously displaying the same vital sign data, the font size, display brightness, or warning information display level can be adjusted according to the current display mode.

[0043] The control module 5 is connected to the display synchronization control module 4 and is used to acquire at least one surgical procedure status, namely the CT scan status and the particle implantation operation status, and control the display mode of the first display unit 2 and the second display unit 3 according to the surgical procedure status. The control module 5 can determine the current surgical procedure status based on the CT equipment working signal, the CT protective door opening and closing signal, the manual operation input signal, or the preset surgical stage signal.

[0044] Specifically, when the control module 5 receives a CT protective door closing signal or a CT equipment scanning start signal, it determines that it is currently in CT scanning mode and controls the second display unit 3 to enter the external priority display mode. In the external priority display mode, the second display unit 3 can increase the display brightness, increase the font size of key vital signs parameters, or increase the display priority of warning information, so that medical staff in the control room can observe the patient's vital signs data through the observation window or lead glass. At this time, the first display unit 2 still maintains synchronous display of vital signs data and is not turned off.

[0045] When the control module 5 receives a CT protective door opening signal, a particle implantation operation input signal, or a corresponding preset surgical stage signal, it determines that it is currently in a particle implantation operation state and controls the first display unit 2 to enter the internal priority display mode. In the internal priority display mode, the first display unit 2 can increase the display brightness, increase the font size of key vital signs parameters, or increase the display priority of warning information, so that medical staff inside the CT room can observe the patient's status when performing puncture, positioning, or particle implantation operations. At this time, the second display unit 3 still maintains synchronous display of vital signs data for continuous observation or auxiliary judgment by personnel in the control room.

[0046] In one implementation, after detecting a switch between the CT scan state and the particle implantation operation state, the control module 5 completes the priority display mode switching between the first display unit 2 and the second display unit 3 within 0.1 to 2 seconds. Further, when the control module 5 receives a CT protective door closing signal, it can control the second display unit 3 to enter the external priority display mode within 500 ms; when the control module 5 receives a CT protective door opening signal, it can control the first display unit 2 to enter the internal priority display mode within 500 ms. Through the above response time settings, the system can quickly follow the operation process of medical personnel entering and leaving the CT room to switch display priorities, reducing display mode lag.

[0047] In one embodiment, the control module 5 includes a microprocessor, a memory, a communication interface, and a status recognition interface. The memory stores a display mode switching program, which the microprocessor executes to control the display modes of the first display unit 2 and the second display unit 3 according to the surgical procedure status. The communication interface receives data output from the vital signs monitoring host 1 or interacts with the display synchronization control module 4. The status recognition interface receives CT equipment operating signals, CT protective door opening / closing signals, manual operation input signals, or preset surgical stage signals. Through this hardware structure, the control module 5 can recognize the surgical procedure status and automatically control the switching of display modes.

[0048] The control module 5 can also be connected to a human-machine interface (HMI) input unit. The HMI input unit includes at least one of a foot switch, physical buttons, a touch input unit, and a voice input unit. Medical staff can input display mode switching commands through the HMI input unit, and the control module 5 controls the first display unit 2 or the second display unit 3 to enter the corresponding priority display mode based on the display mode switching command. This manual intervention method can supplement the automatic recognition method, facilitating temporary adjustments by medical staff according to the actual surgical progress and observation needs.

[0049] The anti-interference communication module 6 is connected between at least two of the vital signs monitoring host 1, the display synchronization control module 4, the first display unit 2, and the second display unit 3, and is used to transmit vital signs data in an electromagnetic interference-resistant manner under CT scanning conditions. The anti-interference communication module 6 may include at least one of the following: shielded cable, fiber optic communication unit, filtering circuit, isolation circuit, and grounding shielding structure.

[0050] Specifically, the shielded cable can be installed between the vital signs monitoring host 1 and the display synchronization control module 4, or between the display synchronization control module 4 and the first display unit 2 and the second display unit 3. The shielding layer of the shielded cable can be connected to the grounding end to reduce the impact of external electromagnetic interference on the communication line. The fiber optic communication unit can include an electro-optic converter, a fiber optic transmission line, and a photoelectric converter, so that vital signs data are transmitted through fiber optics after electro-optic conversion, and then output to the display synchronization control module 4 or the corresponding display unit after photoelectric conversion. The filtering circuit can be installed on the communication line to suppress high-frequency interference signals; the isolation circuit can be implemented by means of optocoupler isolation, digital isolator, or isolated power supply to reduce interference coupling between different circuit modules; the grounding shielding structure can be installed in the communication line, the display module shell, or the main body of the equipment to improve the overall anti-interference capability.

[0051] In one implementation, the data transmission error rate of the anti-interference communication module 6 is no higher than 10. -6 The electromagnetic interference suppression frequency range is 10kHz to 1GHz, the anti-interference strength of the communication signal is not less than 10V / m, the signal transmission delay is not higher than 200ms, and the shielding effectiveness of the grounding shielding structure is not less than 40dB. Through the above settings, the anti-interference communication module 6 can reduce the impact of electromagnetic interference on the data transmission of vital signs during CT scanning, so that the first display unit 2 and the second display unit 3 can maintain a relatively stable synchronous display.

[0052] The risk warning module 7 is connected to the vital signs monitoring host 1 and the display synchronization control module 4. It is used to compare vital signs data with preset abnormal thresholds and generate an abnormal warning signal when at least one of heart rate, blood oxygen saturation, and blood pressure exceeds the corresponding preset abnormal threshold. The preset abnormal thresholds can be set by medical staff according to the patient's actual situation, or the default thresholds in the vital signs monitoring host 1 can be used.

[0053] In one implementation, when a patient's heart rate is higher than a preset upper limit or lower than a preset lower limit, or blood oxygen saturation is lower than a preset blood oxygen threshold, or blood pressure is higher than a preset upper limit or lower than a preset lower limit, the risk warning module 7 generates an abnormal warning signal. To avoid false alarms caused by instantaneous fluctuations, the risk warning module 7 can also be set with a duration judgment condition, such as generating an abnormal warning signal when the corresponding vital sign parameter is continuously within the abnormal range for a preset time.

[0054] Upon receiving an abnormal warning signal, the display synchronization control module 4 causes the first display unit 2 and the second display unit 3 to synchronously output warning prompts. The warning prompts from the first display unit 2 may include at least one of the following: sound prompts, light prompts, flashing displays, and color-changing displays. The warning prompts from the second display unit 3 may include at least one of the following: highlight displays, flashing displays, color-changing displays, and magnified displays. Since the first display unit 2 faces the interior of the CT room, it is suitable to combine sound prompts, light prompts, or interface flashing to alert operators in the room. Since the second display unit 3 faces the observation direction of the control room, it is suitable to use highlighting, flashing, color-changing, or magnified displays to facilitate observation from a distance by personnel in the control room.

[0055] In one implementation, after detecting abnormal vital signs, the risk warning module 7 triggers the first display unit 2 and the second display unit 3 to simultaneously output an abnormality warning prompt within 100ms to 1s. This response time setting reduces the delay between the occurrence of an abnormal state and the prompts from both ends, enabling medical staff in different spaces to quickly obtain information about the patient's abnormality.

[0056] In one embodiment, the system further includes a local cache module. The local cache module caches vital sign data from the most recent 30 seconds to 5 minutes when the anti-interference communication module 6 experiences a communication anomaly, and provides this data for display by the first display unit 2 and the second display unit 3. The local cache module can be located within the display synchronization control module 4, or it can be connected to the display synchronization control module 4 as an independent storage unit. When the anti-interference communication module 6 experiences a short-term communication anomaly, the local cache module can save the vital sign data for the most recent period, allowing the display units to retrieve historical data for display or supplement the display after communication is restored. This facilitates medical personnel's understanding of changes in the patient's vital signs before and after the communication anomaly.

[0057] This embodiment also provides a CT-guided particle implantation bidirectional monitoring method, applied to the aforementioned CT-guided particle implantation bidirectional monitoring system. The method includes the following steps: Collect vital sign data of patients during CT-guided particle implantation; The vital signs data are simultaneously output to the first display unit 2 facing the interior of the CT room and the second display unit 3 facing the observation direction of the control room; Acquire at least one surgical procedure status, either the CT scan status or the particle implantation operation status; When it is determined that the current state is a CT scan, the second display unit 3 is controlled to enter the external priority display mode; When it is determined that the current state is in particle implantation operation, the first display unit 2 is controlled to enter the internal priority display mode. The vital signs data are transmitted in an anti-electromagnetic interference manner through the anti-interference communication module 6. The system determines whether the patient is in an abnormal state based on vital signs data, and when the patient is determined to be in an abnormal state, the first display unit 2 and the second display unit 3 simultaneously output warning prompts.

[0058] Furthermore, acquiring the surgical procedure status includes acquiring at least one of the following: CT equipment operating signal, CT protective door opening / closing signal, manual operation input signal, and preset surgical stage signal. Specifically, upon acquiring a CT protective door closing signal or a CT equipment scanning operating signal, it is determined that the current state is CT scanning, and the second display unit 3 is controlled to enter the external priority display mode. Upon acquiring a CT protective door opening signal or a particle implantation operation input signal, it is determined that the current state is particle implantation operation, and the first display unit 2 is controlled to enter the internal priority display mode. When at least one of the vital signs data—heart rate, blood oxygen saturation, and blood pressure—exceeds the corresponding preset abnormal threshold, an abnormal warning signal is generated, and the first display unit 2 and the second display unit 3 simultaneously output a warning prompt.

[0059] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
