Description

Technical Field

[0001] The present invention relates to the technical field of biliary stents, and particularly to an automated monitoring system for biliary stents based on wireless transmission. Background Art

[0002] The postoperative monitoring of patients with implanted biliary stents mainly relies on manual measurement by nurses (such as indirectly evaluating pressure or drainage volume through external devices), which has the following defects: 1. Complicated operation: It is necessary to frequently go to the bedside for operation, occupying nursing resources; 2. Discontinuous data: Only discrete time-point data can be obtained, and the biliary state cannot be reflected in real time; 3. Poor patient experience: Nighttime measurement may interfere with the patient's rest; 4. Response lag: Abnormal data needs to be manually reported to the doctor, thus delaying the treatment opportunity.

[0003] Although some wireless monitoring technologies are currently applied to other medical scenarios (such as electrocardiogram monitoring), they have not been deeply integrated with biliary stents, and there is a lack of seamless docking solutions with existing hospital systems (such as call systems and electronic medical records). Summary of the Invention

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide an automated monitoring system for biliary stents based on wireless transmission, which is used to solve the problems that the postoperative monitoring of patients with implanted biliary stents mainly relies on manual measurement by nurses, and manual measurement has the problems of complicated operation, discontinuous data, poor patient experience and response lag.

[0005] To achieve the above purpose and other related purposes, the present invention provides the following technical solutions:

[0006] An automated monitoring system for biliary stents based on wireless transmission, including a sensor module, a data preprocessing unit and a doctor terminal module installed on the biliary stent. The sensor module is respectively connected to the data preprocessing unit and the doctor terminal module. The data preprocessing unit includes a call system terminal module arranged beside the patient's hospital bed or a microprocessor module installed on the biliary stent. The sensor module is used to collect parameter information in the patient's biliary tract, encapsulate the parameter information into a data packet according to a preset protocol, and then send the data packet to the call system terminal module or the microprocessor module through a Bluetooth module. Among them, the parameter information in the patient's biliary tract includes the pressure on the inner wall of the patient's biliary tract, the flow rate and velocity of bile in the patient's biliary tract.

[0007] The call system terminal module or the microprocessor module is used to receive the data packets sent by the sensor module, preprocess the data packets, and then send the preprocessed data packets to the doctor terminal device in the doctor terminal module corresponding to the patient. Among them, the preprocessing includes data cleaning and format conversion of the data packets; the doctor terminal module is used to receive the preprocessed data packets sent by the call system terminal module or the microprocessor module, then parse and perform anomaly judgment on the preprocessed data packets, and then display the parameter information detected by the sensor module and the anomaly judgment result.

[0008] In an embodiment of the present invention, the sensor module includes a pressure sensor sub-module for real-time monitoring of the pressure change of the inner wall of the patient's bile duct and a flow sensor sub-module for real-time monitoring of the flow rate and velocity of bile in the patient's bile duct. Bluetooth modules are provided in both the pressure sensor sub-module and the flow sensor sub-module.

[0009] In an embodiment of the present invention, the data packets include patient ID, measurement time, measurement parameter type, and specific values of the parameters. Among them, before installing the bile duct stent in the patient's body, each bile duct stent will be encoded, and each bile duct stent has a unique code, and the code can be bound to the identity code of the patient associated in the hospital information system.

[0010] In an embodiment of the present invention, the call system terminal module includes a call system terminal device, and a Bluetooth receiving module is provided in the call system terminal device. After implanting the bile duct stent into the patient's body, the medical staff inputs the code of the bile duct stent or manually inputs the patient ID through the call system terminal device to complete the device-patient-bed number binding.

[0011] In an embodiment of the present invention, the microprocessor module includes a microprocessor, and a data acquisition module, a data processing module, a wireless transmission module, and a low-power Bluetooth chip are integrated in the microprocessor.

[0012] In an embodiment of the present invention, the data cleaning and format conversion of the data packets include: eliminating duplicate or invalid data within the same time period, converting the data packets after data cleaning into the standard data format of the hospital intranet, and automatically associating them with the electronic medical record system.

[0013] In an embodiment of the present invention, the doctor terminal module includes a doctor terminal device. When the doctor terminal device performs an abnormality judgment on the preprocessed data packet and then displays the parameter information detected by the sensor module and the abnormality judgment result, the following steps are included: obtaining an initial threshold preset according to different disease types of each patient, comparing the parameter information in the data packet with the initial threshold, judging whether the parameter information in the data packet is abnormal according to the comparison result, and displaying the parameter information detected by the sensor module and the comparison result.

[0014] In an embodiment of the present invention, the initial monitoring threshold is automatically set according to the threshold library, and the doctor side can customize it according to needs, so as to complete the setting of the initial threshold. The establishment process of the threshold library includes the following steps: obtaining the parameter information in the patient's biliary tract collected by the sensor module on the biliary stent multiple times, and classifying the parameter information in the patient's biliary tract collected according to different disease types; determining the mean value of the parameter information in the patient's biliary tract of each classified disease type, determining the threshold corresponding to each disease type according to the mean value of each disease type, and establishing a threshold library according to the thresholds corresponding to each disease type.

[0015] In an embodiment of the present invention, the doctor terminal module will automatically record the historical data of the same patient. When the measured values reach and exceed the initial threshold for N consecutive times, the "warning mode" will be triggered to prompt the doctor to evaluate whether it is necessary to adjust the initial threshold or pay attention to the patient's condition. The doctor can calibrate the initial threshold with one key through the terminal interface, and the calibration record is automatically archived for future reference.

[0016] In an embodiment of the present invention, when displaying the parameter information detected by the sensor module and the comparison result on the doctor terminal device, the latest pressure and flow values and change trends will be displayed; at the same time, a standardized table sorted by time will be displayed; and the values exceeding the initial threshold will be highlighted in red font / background, and the abnormal time period will be marked on the three-dimensional trend graph displayed on the doctor terminal device; the associated data before and after the abnormal time point will be automatically retrieved.

[0018] In the present invention, the sensor module installed on the biliary stent can collect parameter information in the patient's biliary tract. The call system terminal module or the microprocessor module can receive the data packet sent by the sensor module and preprocess the data packet. The doctor terminal module can receive the preprocessed data packet sent by the call system terminal module or the microprocessor module, then obtain the initial threshold preset according to different disease types of each patient, compare the parameter information in the data packet with the initial threshold, and judge whether the parameter information in the data packet is abnormal according to the comparison result, so as to facilitate the doctor to timely understand the complex pathological changes and bile flow-related characteristics in the patient's biliary tract; by combining with a new type of biliary stent that can measure relevant data in the biliary tract, the present invention constructs an innovative nursing process for patients after hepatobiliary surgery. By replacing the traditional manual monitoring with an automated process, the data measured by the biliary stent is timely fed back to the doctor, so as to facilitate the doctor's timely clinical diagnosis and give corresponding treatment.

[0028] 1. Biliary stent; 2. Pressure sensor sub-module; 3. Flow sensor sub-module; 4. Microprocessor module. Specific Embodiment

[0029] The following uses specific examples to illustrate the embodiments of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] The first embodiment of the present invention relates to an automated monitoring system for biliary stents based on wireless transmission. Specifically, please refer to Figures 1 to 4 , which includes a sensor module installed on the biliary stent 1, a call system terminal module and a doctor terminal module set beside the patient's hospital bed. The sensor module is respectively connected to the call system terminal module and the doctor terminal module.

[0031] The sensor module is used to collect parameter information in the patient's biliary tract, encapsulate the parameter information into a data packet according to a preset protocol, and then send the data packet to the call system terminal module through a Bluetooth module. Among them, the parameter information in the patient's biliary tract includes the pressure on the inner wall of the patient's biliary tract, the flow rate and velocity of bile in the patient's biliary tract; the data packet includes the patient ID (each biliary stent 1 has a unique code, and the code can be bound to the identification code of the patient associated in the hospital information system), the measurement time (in minutes), the type of measurement parameter (such as pressure value, flow value), and the specific value of the parameter (the unit is standardized to mmHg, mL / h); it should be noted that the sensor module includes a pressure sensor sub-module 2 for real-time monitoring of the pressure change on the inner wall of the patient's biliary tract and a flow sensor sub-module 3 for real-time monitoring of the flow rate and velocity of bile in the patient's biliary tract. Both the pressure sensor sub-module 2 and the flow sensor sub-module 3 are provided with Bluetooth modules; the Bluetooth module uses the Bluetooth 5.0 BLE protocol, and transmits at a fixed interval (such as every 1 hour) or in a disease emergency trigger mode (such as a parameter mutation exceeding 10%), and the transmission power is adjustable to adapt to different ward environments.

[0032] The call system terminal module is used to receive the data packets sent by the sensor module, preprocess the data packets, and then send the preprocessed data packets to the doctor terminal device in the doctor terminal module corresponding to the patient. Among them, the preprocessing includes data cleaning and format conversion of the data packets. The specific steps of data cleaning and format conversion include: removing duplicate or invalid data within the same time period, converting the data packets after data cleaning into the standard data format of the hospital intranet, and automatically associating with the electronic medical record system. It should be noted that the call system terminal module includes a call system terminal device, and a Bluetooth receiving module is provided in the call system terminal device. When the call system terminal device performs identity binding: after the biliary stent 1 is implanted into the patient's body, the medical staff inputs the coding of the biliary stent 1 or manually inputs the patient ID through the call system terminal device to complete the device-patient-bed number binding. The call system terminal device is also used for signal filtering: the call system terminal device only receives the data packets of the bound stents and shields the interference of other devices. The call system terminal device can temporarily store the received data packets to avoid data loss caused by network interruption.

[0033] The doctor terminal module is used to receive the preprocessed data packets sent by the call system terminal module, then parse and perform anomaly judgment on the preprocessed data packets, and then display the parameter information detected by the sensor module and the anomaly judgment results. Among them, the call system terminal module will automatically match the responsible doctor (such as the attending doctor, the on-duty doctor) according to the patient ID and push the preprocessed data packets to their doctor computer terminals. It should be noted that the doctor terminal module includes a doctor terminal device. When the doctor terminal device performs anomaly judgment on the preprocessed data packets and then displays the parameter information detected by the sensor module and the anomaly judgment results, the following steps are included: obtaining the initial thresholds preset according to different diseases of each patient, comparing the parameter information in the data packets with the initial thresholds, judging whether the parameter information in the data packets is abnormal according to the comparison results, and displaying the parameter information detected by the sensor module and the comparison results.

[0034] In the entire monitoring and early warning system, a threshold early warning and feedback mechanism is included. The threshold early warning includes: presetting the initial thresholds (such as after biliary cancer surgery: pressure > 25 mmHg, flow < 8 mL / h) for different diseases (such as cholangiocarcinoma, gallstones) according to clinical practice guidelines and case databases. For another example, the pressure threshold in the common bile duct area of the normal biliary tract is about 800 - 1100 Pa, and the pressure threshold in the common bile duct area of patients with choledochal cysts is about 100 - 400 Pa. After the patient is implanted with the biliary stent 1, the doctor terminal device automatically obtains the age and gender information according to the patient ID and matches the corresponding initial threshold.

[0035] Static Threshold Setting: The initial monitoring threshold is automatically set according to the threshold library, and the doctor can customize it according to needs to complete the setting of the initial threshold. The establishment process of this threshold library includes the following steps: Obtain the parameter information in the patient's biliary tract collected by the sensor module on the biliary stent 1 multiple times, and classify the collected parameter information in the patient's biliary tract according to different diseases; Determine the mean value of the parameter information in the patient's biliary tract for each disease after classification, determine the threshold corresponding to each disease according to the mean value of each disease, and establish a threshold library according to the threshold corresponding to each disease; Also, the process of determining the threshold corresponding to each disease according to the mean value of each disease is as follows: The sensor module on the biliary stent 1 can collect the parameter information in each patient's biliary tract, and then all the collected parameter information is integrated to form a database. Then, for each patient's information collected, the doctor judges the collected information according to clinical experience to determine whether the collected pressure data is too large or too small. Therefore, through clinical practice guidelines, case databases, and the doctor's diagnosis, the threshold corresponding to each disease can be obtained. For the specific process, please refer to Figure 8 ;

[0036] Dynamic Threshold Optimization: The system automatically records the historical data of the same patient. When the measured values reach and exceed the initial threshold for 3 consecutive times, the "warning mode" is triggered, prompting the doctor to evaluate whether it is necessary to adjust the initial threshold or pay attention to the patient's condition. The doctor can calibrate the initial threshold with one key through the terminal interface, and the calibration record is automatically archived for future reference; Define the abnormal prompt for associated parameters. For example: Pressure > 20 mmHg and Flow < 5 mL / h → High-risk biliary obstruction; Pressure sudden increase > 30% and Flow continuously decreasing > 1 hour → Suspected stent displacement. When the composite event is triggered, the system automatically associates the patient's imaging data (such as CT scans) in the electronic medical record and pushes a list of suspected diagnoses (such as cholangitis, stent blockage);

[0037] The feedback mechanism includes: The doctor disposes of the feedback loop according to the data displayed on the doctor's terminal device: The doctor selects the final diagnosis result (such as "biliary tract infection") on the terminal, issues medical orders, and pushes the treatment plan; Customizable monitoring frequency: According to the characteristics of this event, the doctor can customize and adjust the monitoring frequency to achieve the purpose of monitoring the patient's condition at any time;

[0038] Data Display Forms: 1. Real-time Dashboard: Displays the latest pressure, flow values, and change trends; 2. Historical Data Table: A standardized table sorted by time (simulating the style of a blood routine report); 3. Abnormal Highlight Marking: Values exceeding the threshold are highlighted in red font / background; Visualization of Abnormal Data: It can also mark the abnormal time period on the three-dimensional trend graph (time-pressure-flow linkage curve) displayed on the doctor's terminal device; At the same time, it can automatically retrieve the associated data before and after the abnormal time point (such as concurrent medication records, body temperature changes).

[0039] Specifically, the first embodiment of the present invention is directed to the process of processing the parameter information of the patient's biliary tract collected by the sensor module when the microprocessor module is not installed on the biliary stent 1; there is also system compatibility design: hardware reuse: directly utilize the power supply, network interface and display screen of the existing call system terminal, only need to upgrade the Bluetooth module and software system, and there is no need to add new hardware devices; protocol compatibility: support docking with the APIs of mainstream electronic medical record systems (such as Epic, Cerner) to ensure that data is automatically archived to the patient's medical record.

[0040] The second embodiment of the present invention relates to an automated monitoring system for biliary stents based on wireless transmission. For details, please refer to Figure 1 、 Figures 5 to 7 , including a sensor module, a microprocessor module 4 and a doctor terminal module installed on the biliary stent 1. The sensor module is respectively connected to the microprocessor module 4 and the doctor terminal module.

[0041] The sensor module is used to collect the parameter information of the patient's biliary tract, encapsulate the parameter information into a data packet according to a preset protocol, and then send the data packet to the microprocessor module 4 through the Bluetooth module. Among them, the parameter information of the patient's biliary tract includes the pressure of the inner wall of the patient's biliary tract, the flow rate and velocity of bile in the patient's biliary tract.

[0042] The microprocessor module 4 is used to receive the data packet sent by the sensor module, preprocess the data packet, and then send the preprocessed data packet to the doctor terminal device in the doctor terminal module corresponding to the patient. Among them, the preprocessing includes data cleaning and format conversion of the data packet; it should be noted that the microprocessor module 4 includes a microprocessor, and the microprocessor integrates a data acquisition module, a data processing module, a wireless transmission module and a low-power Bluetooth chip.

[0043] The doctor terminal module is used to receive the preprocessed data packet sent by the microprocessor module 4, then parse and perform anomaly judgment on the preprocessed data packet, and then display the parameter information detected by the sensor module and the anomaly judgment result.

[0044] Specifically, the second embodiment of the present invention is directed to the process of processing the parameter information of the patient's biliary tract collected by the sensor module when the microprocessor module is installed on the biliary stent 1; the present invention is used to monitor the pressure and bile flow data in the biliary tract of patients implanted with the biliary stent 1 in real time and automatically, and integrate the data into the doctor terminal of the hospital intranet through wireless transmission, solving problems such as low efficiency of traditional manual measurement, disturbing patients' rest at night, and poor timeliness of data, and is applicable to scenarios such as postoperative monitoring in hepatobiliary surgery and management of chronic biliary diseases.

[0045] In summary, the present invention has the following beneficial effects: First, the present invention can improve the monitoring efficiency: through fully automatic data collection and transmission, the manual operations of nurses are reduced, and the labor cost is lowered; Second, the present invention can optimize the patient experience: disturbing the patient's rest during night-time measurements is avoided, and the comfort level is improved; Third, the present invention can achieve real-time early warning: through automatic threshold alarms, the response time to abnormal conditions is shortened, and the risk of complications is reduced; Finally, the present invention can reduce the deployment cost: the existing hospital call system and network facilities are reused, and complex equipment transformation is avoided.
