The in-vitro data management device M300 and the cloud server M400 may communicate with each other wirelessly or by wire. The cloud server M400 and the first user end may be in wireless or wired communication. The first user side may include, for example, a doctor side, a patient side, and/or a patient family side, among others. The first user side refers to terminal equipment used by a user or a software side (an APP (application) of a mobile phone, a web page side and the like) corresponding to the user. The processing according to the preset processing rules can include, for example, grouping the heart state data according to different dimensions of a patient, time, region and/or type, performing data format adjustment on the heart state data, and the like. The cloud server M400 may process the heart status data of a patient and send the processed heart status data to a doctor end, a patient end and/or a patient family end corresponding to the patient. Through the data integration function of the cloud server M400 of the system, big data medical treatment is possible, and the cloud server M400 can conduct screening classification according to patient data, so that an analysis prediction report is provided for doctors, and the development progress of the patient diseases is prompted.
In this embodiment, the processing, by the cloud server M400, the cardiac status data according to a preset processing rule includes: the cloud server M400 groups the heart status data according to specified dimensions (such as patient, time, region and/or category, etc.), so as to obtain a plurality of groups of heart status data, and determines a second user terminal corresponding to each group of heart status data from the first user terminals, that is, the second user terminal is selected from the first user terminals and is associated with each group of heart status data. For example, for cardiac state data grouped in patient dimensions, the second user side corresponding to the cardiac state data of a particular patient includes a doctor side corresponding to the patient, a patient side, and a patient family side, where the doctor side refers to a doctor side used by a designated doctor, and the designated doctor refers to a particular doctor responsible for the patient; for heart state data grouped in regional dimensions, a second user end corresponding to the heart state data of a specific region comprises a staff end responsible for managing the regional data; the heart status data classified by type, the second user side corresponding to the heart status data of a specific type comprises a staff side needing trend analysis by using the heart status data of the specific type.
In this embodiment, after the cloud server M400 groups the cardiac status data according to specified dimensions (such as patient, time, region and/or category, etc.), a doctor may choose to view cardiac status data in one or more dimensions when the doctor is viewing the cardiac status data. For example, in a data display interface pushed to a doctor terminal, a drop-down selection frame of each dimension is displayed, and the doctor terminal can select a specific dimension in the drop-down selection frame of each dimension, so that the purpose of viewing heart state data of a specific dimension is achieved.
In this embodiment, after determining the second user end corresponding to each group of the cardiac status data, the cloud server M400 further determines a corresponding data pushing mode according to the category of the cardiac status data, and sends a viewing reminder to the second user end corresponding to the cardiac status data, where the viewing reminder is sent in the data pushing mode. The viewing reminding can be, for example, a mail, a short message or a WeChat reminding sent to the second user side, or a popup reminding jumped out at the second user side. The viewing reminder includes a brief introduction of the data to be pushed (such as a patient name, a data type, or a data generation time) and a link of the data to be pushed. After receiving the viewing prompt, the user can click on the link in the viewing prompt, namely, initiate a data viewing request to the cloud server M400.
The cloud server M400 sends the processed data to the first user terminal, including: the cloud server M400 responds to the data viewing request of the first user side, obtains viewing authority and operation authority of the first user side, generates a data display interface and pushes the data display interface to the first user side, wherein the data display interface comprises a display area and an operation area, the display area displays the viewing authority to determine corresponding heart state data, and the operation area displays an operation entry corresponding to the operation authority, and the operation entry comprises an operation button. The cloud server M400 is further configured to respond to the operation of the first user side in the operation area, and execute a data processing task corresponding to the operation. For example, if the viewing authority of a doctor is the heart status data of the associated patient, the heart status data of the associated patient is displayed in the display area. The operation authority of the doctor end comprises, for example, checking, screening and/or marking the heart state data, generating a heart state data analysis report, setting equipment configuration information of medical equipment of a certain patient, and prescribing consultation time with a certain patient, etc., and then generating a data display interface for the doctor end, wherein the operation area of the data display interface is also provided with corresponding entries of the operations.
In this embodiment, different data display interface templates are configured for the first user ends of the various operation rights in advance, and the cloud server M400 stores the data display interface templates corresponding to the first user ends of the various operation rights. For example, a data display interface template corresponding to a doctor end, a data display interface template corresponding to a patient end, and a data display interface template corresponding to a staff end are preset, and when receiving a data viewing request of a first user end, the cloud server M400 generates a data display interface, which includes: and calling a corresponding data display interface template according to the operation authority of the first user side, wherein the data display interface template comprises an operation area and a display area, and the operation area displays an operation inlet corresponding to the operation authority. And then the cloud server M400 invokes heart state data which can be checked by the first user terminal according to the checking authority of the first user terminal, fills the invoked heart state data into the display area of the data display interface template, and obtains a data display interface corresponding to the first user terminal, and then pushes the data display interface to the first user terminal. Further, the doctor may select the heart status data to be checked through the doctor terminal, and the cloud server M400 invokes the heart status data to be checked (satisfying that the first user terminal has the checking authority) according to the selection of the first user terminal, and fills the display area of the data display interface template.
For example, the designated doctor may use the terminal device or log in the doctor terminal on the web page, and after receiving the viewing prompt, select the data to be viewed and click on the corresponding link, and send a data viewing request to the cloud server M400. The cloud server M400 pushes the data display interface to the doctor end, and the doctor end can view the data of the patient in the display area. The designated doctor can find an operation entry for setting device configuration information in the operation area, click on a configuration interface for entering the device configuration information, and adjust the device configuration information of the implanted medical device M100 thereof in the configuration interface according to the condition of the patient. If the doctor wants to see the electrocardiographic parameters of the patient for the next three days, the doctor can configure corresponding heart monitoring parameters in the equipment configuration information through the doctor side. The device configuration information can remotely configure the implanted host through paths of the doctor end, the cloud server M400, the extracorporeal data management device M300 and the implanted medical device M100. Therefore, by adopting the heart monitoring system, accurate heart state data can be obtained based on the implanted medical device M100, and detection tracking and disease course management of heart disease progress of a patient at a doctor end and/or a patient end can be satisfied. So that the patients can fully benefit after the implantation operation and systematically treat and manage heart diseases. Not only the life of the patient is guarded for 24 hours, but also doctors can administer reasonable medicines according to the development of the illness state of the patient.
In this embodiment, different categories of the heart state data correspond to different data push modes. For example, the cloud server M400 classifies the heart state data into two categories: category a is cardiac state data of the implantable medical device before and after treatment, which is generated during a treatment process after a patient has a specific cardiac rhythm event; and B category is heart state data acquired by the implantable medical device for a long time according to the device configuration information. The data pushing mode of the class A data is set to be immediately pushed to a designated doctor side, the class B data pushing mode is that when the data quantity or the acquisition time of the heart state data meets pushing requirements, the part of the heart state data is processed based on a preset integration analysis strategy, after a data analysis report is obtained, the viewing reminding of the data analysis report is pushed to the designated doctor side, and the integration analysis strategy comprises calculation of heart state parameters, comparison analysis of the heart state data in different time periods, trend analysis of heart state parameter change, graphical processing of heart state parameter change trend and the like.
For example, whenever a patient in the jurisdiction of a doctor has heart status data of category a, a viewing reminder of the data is immediately pushed to the doctor's end for use by the doctor, and the instant pushing manner may include sending a sms, email, or pop-up window, etc., to require the doctor to view and process the data within a specified time. If the doctor does not check, the doctor is reminded in a certain period cycle, so that the doctor is ensured to receive the data.
For class B heart condition data, the cloud server M400 automatically analyzes the heart condition data for each long-term recording, classifies and records the frequency of various heart rhythm events (such as malignant heart rate, atrial fibrillation, atrial premature, ventricular superior speed, ventricular premature and/or other non-malignant heart rhythm events), and records various parameters of sinus rhythm (R-R interval, R wave amplitude, QRS interval and the like) in the time period. Meanwhile, for patients with multiple sections of long-time heart state data, the cloud server M400 can compare data values in the front and back multiple sections of heart state data, and after a data analysis report showing a change trend is obtained, a viewing prompt of the data analysis report is pushed to a designated doctor end in the form of a short message, a mail, a popup window and the like, and the doctor can click to view the complete data analysis report.
In application, when one doctor faces multiple patients at the same time, there may be a case where a plurality of groups of heart status data of different patients need to be pushed to the doctor at the same time. In this embodiment, in order to facilitate the doctor to view the patient data with more urgent situation in time, the cloud server M400 may prioritize the viewing reminders to be sent in advance, so as to facilitate the doctor to view. The priority sorting mode may be according to a default priority sorting rule, where the default priority sorting rule may be a unified rule, or different types of first user ends respectively correspond to different priority sorting rules. In some embodiments, the prioritization manner may also be according to a prioritization rule set by a doctor, for example, the doctor may select some patients, and make the viewing reminders corresponding to the patients set on top, so that the push priority of the viewing reminders of the patients is higher. Specifically, the cloud server M400 sends a viewing reminder to a second user side corresponding to the cardiac status data, including: when the cloud server M400 determines that the same second user side has multiple groups of viewing reminders to be sent, sorting the viewing reminders according to the push priorities of the viewing reminders, sending the sorted viewing reminders to the second user side, and highlighting or placing the viewing reminders with high push priorities on the forefront side to push the viewing reminders to the doctor side so as to first draw attention of the doctor. Therefore, when receiving a plurality of viewing reminders, the doctor terminal can purposefully and preferentially view the viewing reminders with high pushing priority and click to view the corresponding heart state data, so that the processing of an emergency is prevented from being delayed. The prioritization rules herein order, for example, from high to low based on the push priority of the view reminder, which may be based on a weighted summation of attribute values of a plurality of attributes, which may include the category of heart status data (e.g., category a or category B described above), the patient's chance of developing, the time at which the patient has most recently occurred a malignant heart rhythm event, the number of malignant heart rhythm events that have occurred in the most recent period of time, and the like.
In this embodiment, the implantable medical device M100 is exemplified as an implantable cardiac defibrillator. As shown in fig. 3, the implantable medical device M100 further includes a heart rhythm analysis module and a heart treatment module. The heart rhythm analysis module is used for judging whether a specific heart rhythm event occurs according to the heart state data, for example, the heart rhythm event is identified according to preset judging conditions of the heart rhythm event. The cardiac therapy module is configured to perform a therapeutic action, such as electrical defibrillation therapy of the patient's heart using defibrillation electrodes, when a particular cardiac rhythm event is determined to occur, and to cardiovert the patient's heart when current is passed through the cardiomyocytes. In existing implantable cardiac defibrillators, only a few minutes of cardiac state data before and after a malignant cardiac rhythm event is saved, and therefore the cardiac state data may be quickly overlaid periodically to fail to save long-term continuous monitoring data. In this embodiment, the data storage parameters of the data storage module are set by the device configuration information, so that the data storage module can record all cardiac state data for a specified duration periodically or aperiodically. For example, 24-hour weekly cardiac state data is stored, or 24-hour weekly cardiac state data is stored for two-day/one-month/three-day/month, etc. The starting time of the period of the data storage record may also be arbitrarily configured.
In this embodiment, the extracorporeal data management apparatus M300 is further configured to send apparatus configuration information to the implantable medical apparatus M100 via the charging communication apparatus M200, the apparatus configuration information including cardiac monitoring acquisition parameters and/or data storage parameters. The device configuration information is generally set by a designated doctor according to the condition of the patient, and may be directly transmitted by the designated doctor through operation on the external data management device M300, or may be transmitted to the cloud server M400 by the designated doctor through a doctor end, and then the cloud server M400 transmits to the external data management device M300. For example, the cloud server M400 is further configured to obtain the device configuration information from a doctor end, and send the device configuration information to the implantable medical device M100 through the extracorporeal data management device M300. Therefore, the doctor end can not only follow the progress of the patient's condition in real time, but also can remotely set parameters such as the monitoring duration and the monitoring period of the implantable medical device M100.
As shown in fig. 3, the implantable medical device M100 further includes a configuration module configured to configure the cardiac monitoring acquisition parameters of the cardiac monitoring module and/or the data storage parameters of the data storage module according to the received device configuration information. The cardiac monitoring acquisition parameters include, for example, one or more of parameters such as an acquisition frequency of the cardiac monitoring module, an acquisition time point of the cardiac monitoring module (e.g., 3 pm per day/day of the end of each month 5, etc.), and/or an acquisition duration of the cardiac monitoring module (e.g., 24 hours per day/8 a early day to 8 a late day, etc.), the data storage parameters include, for example, one or more of a frequency with which the data storage module stores the cardiac state data (e.g., once per month/three times per month, etc.), a time period during which the cardiac state data is stored (e.g., 24 hours per time of storage/6 hours per time of storage, etc.), what cardiac state data is stored, or what amount of data is cleaned up, etc.
In this embodiment, the device configuration information may further include a specific cardiac rhythm event determination parameter and/or a cardiac therapy parameter, where the specific cardiac rhythm event determination parameter is a specific cardiac rhythm event determination parameter of the cardiac rhythm analysis module, and the cardiac therapy parameter is a cardiac therapy parameter of the cardiac therapy module. The configuration module of the implantable medical device M100 is further configured to configure the specific cardiac rhythm event decision parameters of the cardiac rhythm analysis module and/or the cardiac treatment parameters of the cardiac treatment module according to the received device configuration information. The cardiac rhythm event determination parameters include, for example, a determination that the cardiac rhythm is in a normal range, a ventricular rate occurs, a numerical range of a specific electrocardiographic indicator at the time of ventricular fibrillation occurs, a determination condition of a specific electrocardiographic event requiring initiation of treatment, and the like. The cardiac therapy parameters include, for example, voltage variation parameters and/or therapy time parameters when delivering electrical defibrillation therapy, and the like.
In this embodiment, the wireless communication/wireless charging operation modes between the charging communication device M200 and the implanted medical device M100 are, for example, two types:
(1) When the charging communication device M200 performs a wireless charging task, the charging communication device M200 performs wireless charging on a wireless rechargeable battery of the implanted medical device M100 and performs wireless communication with the implanted medical device M100 to perform a first data transmission task. In this embodiment, the first data transmission task includes acquiring the heart status data from the implantable medical device M100. Because the heart state data often has larger data volume, wireless data transmission is carried out simultaneously in the wireless charging process, excessive loss caused by the residual electric quantity of the power module of the implantable medical device M100 can be avoided, rapid decline of the electric quantity of the implantable medical device M100 caused by data transmission is avoided, and the reliability and stability of the data transmission are improved.
In this embodiment, when the charging communication device M200 performs the wireless charging task, wireless communication with the implanted medical device M100 may be performed using a wireless charged carrier, that is, communication data is loaded on the wireless charged carrier. In this embodiment, when the charging communication device M200 performs the wireless charging task, the wireless charging process and the wireless communication process between the charging communication device M200 and the implanted medical device M100 are controlled based on a specific control manner. The specific control mode comprises a preset multiplexing mode and/or a preset modulation mode. The multiplexing method includes, for example, a time division control method, a frequency division control method, or a time division and frequency division mixed control method, and the modulation method includes, for example, ASK (Amplitude Shift Keying, amplitude shift keying modulation), PSK (Phase Shift Keying, phase shift keying modulation), and/or FSK (Frequency Shift Keying, frequency shift keying modulation). For example, the wireless charging process and the wireless communication process between the charging communication device M200 and the implanted medical device M100 use the same transmission path, and both processes are performed according to a time division control manner or a frequency division control manner.
(2) The charging communication device M200 performs wireless communication with the implantable medical device M100 when receiving a data transmission instruction to perform a second data transmission task. The data transmission instruction may be sent to the charging communication device M200 through the external data management device M300, or may be sent by a user through a button controlling the surface of the charging communication device M200. In this embodiment, the second data transmission task includes the charging communication device M200 transmitting the device configuration information to the implantable medical device M100. Because the device configuration information is generally set by a doctor according to the condition of a patient, the setting time and the wireless charging time are not necessarily consistent, and the flexible transmission of the device configuration information can be realized by transmitting a data transmission instruction, so that the relevant parameters of the implantable medical device M100 can be configured timely according to the instruction of the doctor.
In another embodiment, when the charging communication device M200 performs the wireless charging task, if there is just device configuration information to be transmitted, the device configuration information may also be sent to the implantable medical device M100 at the same time; and/or, the charging communication device M200 acquires heart status data from the implantable medical device M100 upon receiving a data transmission instruction, where the data transmission instruction may further include further refined information such as a data type and/or a time range of acquisition of the heart status data.
In this embodiment, the cloud server M400 is further configured to establish a communication connection between two different first clients associated with the implantable medical device M100 based on a request of the first clients associated with the implantable medical device M100. For example, if one of the implantable medical devices M100 is associated with both the patient side and the doctor side, the cloud server M400 may establish a communication connection between the patient side and the doctor side, where the communication connection may be in the form of text/picture/audio/video communication in the form of a dialog box, or may be a direct voice call/video call, or the like. Therefore, the cloud server M400 may integrate the internet hospital functions, so that the designated doctor and the patient may communicate and communicate in time through a direct communication manner, the designated doctor may prescribe the patient in time, adjust the device configuration parameters of the implanted medical device M100, and the patient may also query his own diagnosis and treatment scheme in time. Therefore, the embodiment can realize absolute remote follow-up of the patient, save a plurality of inconveniences of the patient to the hospital, improve the medical efficiency and promote the experience of seeking doctor.
As shown in fig. 3, in this embodiment, the implantable medical device M100 further includes an alarm module for determining a level of an alarm event and a response requirement that occurs when the implantable medical device M100 has a preset type of alarm event. For example, the alarm event is highest when the implantable medical device M100 encounters a significant abnormality, which affects the protection function of the implantable medical device M100 for the patient, and is lowest when the implantable medical device M100 has a low battery but has not reached an extremely low level, and the alarm event is medium, when the implantable medical device M100 has a small malfunction but does not affect normal use for a short time. The alarm module is further configured to send alarm information to the cloud server M400 via the extracorporeal data management apparatus M300, where the alarm information includes a level of an alarm event occurring and a response requirement, where the response requirement includes, for example, a response personnel range (doctor, patient family and/or emergency personnel, etc.), a response time requirement (immediate response or response within 30 minutes, etc.), and/or a response mode requirement (patient immediately sees doctor or patient family immediately assists, etc.). The alarm information may also include data related to the occurrence of an alarm event, such as operational data of the alarm module and/or current time cardiac state data, etc. The alarm information may be sent directly to the external data management device M300 by the implanted medical device M100 in a wireless manner when an alarm event occurs, or the implanted medical device M100 may be sent to the external data management device M300 by the charging communication device M200. Alternatively, considering that the in-vitro data management device M300 is not necessarily disposed around the implantable medical device M100 in real time, the implantable medical device M100 generates alarm information when an alarm event occurs and stores the alarm information locally, and transmits the locally stored alarm information to the in-vitro data management device M300 when communicating with the in-vitro data management device M300. After receiving the alarm information, the cloud server M400 sends the alarm information to the corresponding first user end according to the level and response requirement of the alarm event, where the corresponding first user end is the first user end associated with the implanted medical device M100 having the alarm event. When receiving the alarm information, the doctor end can reserve corresponding medical resources (including 120 emergency ambulances or hospital visit green channels and the like) in time to respond to the emergency requirement of the patient.
In this embodiment, the power module may have other types of batteries, such as a non-rechargeable battery, in addition to the rechargeable battery, or the power module may be all rechargeable batteries. The power module may be divided into a plurality of battery partitions, each battery partition including at least one rechargeable battery and/or at least one non-rechargeable battery, each battery partition powering a different functional module. As shown in fig. 3, in this embodiment, the implantable medical device M100 further includes a power management module. The power management module can manage each battery partition, monitor the residual electric quantity of each battery partition, and adjust the corresponding power supply relation between the battery partition and the functional module according to the residual electric quantity of each battery partition.
In this embodiment, the power management module is configured to store a correspondence between each remaining power level and each functional mode. The power management module is further configured to monitor a remaining power of the power module, determine a current remaining power level according to the remaining power, determine a functional mode corresponding to the remaining power level, and execute a power management scheme under the functional mode, where the power management scheme includes a switch control scheme of each module and/or a control scheme of a function execution parameter of each module (a heart monitoring parameter of the heart monitoring module, a data storage parameter of the data storage module, and/or a heart treatment parameter of the heart treatment module). For example, when the power module is not partitioned, the power management module monitors the remaining power of the power module as a whole. The remaining power level is classified into three levels, for example: sufficient electric quantity, low electric quantity and extremely low electric quantity. When the electric quantity is sufficient, the power management scheme under the corresponding functional mode can comprise that all functional modules work normally, wherein the heart monitoring module acquires heart state data with higher frequency and precision; when the electric quantity is low, the power management scheme in the corresponding functional mode can comprise the functions of closing the wireless communication module and the configuration module; when the electric quantity is extremely low, the power management scheme in the corresponding functional mode can comprise the functions of closing the wireless communication module, the configuration module and the data storage module, and setting the heart monitoring module to collect heart state data with lower frequency and accuracy, wherein the corresponding relation between the residual electric quantity classification and the power management scheme is only an example.
In one embodiment, the power management module presets a plurality of functional modes, including, for example, the following five functional modes:
(I) Core functional mode: the mode mainly realizes the functions of heart state data acquisition, heart state data analysis, malignant heart rhythm event identification, treatment starting, power management and charging prompt alarm, and the power management scheme corresponding to the functional mode is as follows: starting the functions of a heart monitoring module, a heart rhythm analysis module, a heart treatment module, a power supply module and an alarm module, and controlling the started modules to work according to preset heart monitoring parameters, malignant heart rhythm event judgment conditions, heart treatment parameters and charging prompt alarm thresholds;
(II) treatment recording functional mode: the mode mainly realizes the recording of heart state data and medical equipment parameters before and after the treatment process, and the power management scheme corresponding to the functional mode is as follows: starting the function of the data storage module, and storing the acquired heart state data and medical equipment parameters according to preset data storage parameters;
(III) device operating parameter monitoring functional mode: the mode mainly realizes the self-checking and alarming record of the medical equipment to detect the daily working state of the medical equipment, and the power management scheme corresponding to the functional mode is as follows: starting the functions of the equipment self-checking module and the data storage module;
(IV) wireless communication functional mode: the mode mainly realizes the communication between the medical equipment and the charging communication equipment, and the power management scheme corresponding to the functional mode is as follows: starting the function of the wireless communication module;
(V) long-time signal acquisition functional mode: the mode mainly realizes the collection and storage of long-time heart state data, and the power management scheme corresponding to the functional mode is as follows: and starting the functions of the heart monitoring module and the data storage module, and controlling the heart monitoring module according to the configured acquisition frequency, acquisition precision and continuous acquisition time of long-time data acquisition.
The priorities of the five functional modes decrease in sequence. When the remaining power is high, all functional modes can be turned on. When the electric quantity is low, the implementation of the function mode with high priority is ensured first, and the function mode with low priority can be correspondingly closed. The remaining power level and the functional mode may be in a one-to-one, one-to-many, or many-to-one relationship. For example, five remaining power levels 1-5 are set in the power management module, the corresponding remaining power ranges are sequentially reduced, the remaining power level 1 corresponds to the function modes I, II, III, IV and V, the remaining power level 2 corresponds to the function modes I, II, III and IV, that is, the power management scheme of the long-time signal acquisition function mode is not executed any more, the remaining power level 3 corresponds to the function modes I, II and III, the remaining power level 4 corresponds to the function modes I and II, the remaining power level 5 corresponds to the function mode I, that is, when the power is very low, only the normal execution of the power management scheme of the function mode I is preferentially ensured.
