Description

Technical Field

[0001] This invention belongs to the field of vascular interventional therapy nursing management technology, specifically a vascular interventional therapy catheter placement safety management and nursing decision support system. Background Technology

[0002] During vascular interventional treatment, post-catheter placement nursing management spans multiple stages, including post-placement observation, routine maintenance, patient activity or transfer, and nursing handover. During the placement period, the catheter not only serves as a pathway for infusion, monitoring, or treatment, but also needs to remain relatively stable under conditions of changes in patient position, changes in local fixation status, and continuous nursing procedures. Therefore, the assessment of the catheter's status and nursing care during the placement period require continuity and coordination.

[0003] In current clinical nursing practice, the status management after catheter placement is usually determined and handled by nursing staff based on bedside rounds, local observation, infusion equipment operation, and handover records. For scenarios such as patient turning over, getting out of bed, transfer, continued infusion, and nursing handover, nursing staff usually need to check the catheter fixation, puncture site, lumen patency, dressing status, and maintenance completion before deciding whether to perform subsequent nursing procedures. Relevant information is mostly scattered in infusion equipment records, bedside rounds records, nursing treatment records, and handover records, and the connection between different links mainly relies on manual data entry, manual verification, and verbal handover.

[0004] Because the current approach lacks a unified mechanism for assessing and continuously linking the local condition of the catheter, the patient's activity level, the catheter's usage status, and the nursing care status, the existing nursing management process is prone to issues such as delayed risk identification, inconsistent review content, and insufficient continuation of unfinished matters after handover. As a result, relevant risk matters may enter subsequent nursing stages before they have been properly addressed. Summary of the Invention

[0005] This invention relates to the field of vascular interventional therapy nursing management technology, specifically to a vascular interventional therapy catheter placement safety management and nursing decision support system.

[0006] The system integrates catheter placement records, bedside status information, and nursing procedures into the same processing chain. When a risk is identified, a review task corresponding to the source of the risk is generated. Before the review is completed, the system restricts the confirmation of the completion of related nursing operations. After the handover of nursing care, the system continues to maintain processing constraints on unfinished matters, thereby ensuring that catheter placement safety management is consistent with the nursing procedure.

[0007] The system provided by this invention includes a bedside information acquisition terminal, a nursing interaction terminal, and a safety decision-making host. The bedside information acquisition terminal is used to collect bedside status information related to the indwelling catheter of the target patient and send the bedside status information to the safety decision-making host. The nursing interaction terminal is used to receive review tasks, enter review results, and submit nursing operation completion confirmation requests. The safety decision-making host is connected to the bedside information acquisition terminal and the nursing interaction terminal, and is used to perform correlation processing on catheter indwelling records, bedside status information, and nursing treatment results, and control the processing status of the nursing interaction terminal on nursing operation completion confirmation requests according to the processing results.

[0008] The safety decision-making host includes a file creation unit, a rule determination unit, a status association unit, a review and control unit, and a handover and continuation unit. The file creation unit is used to create a catheter placement file for the target patient. The catheter placement file includes catheter type, placement site, placement side, fixation method, maintenance cycle, placement stage, and handover and review items. The above file content is used to describe the current basic information, maintenance requirements, and handover requirements of the catheter placement, providing a data foundation for subsequent rule determination and risk assessment.

[0009] The rule-determining unit is used to determine the indwelling safety rules corresponding to the current indwelling stage based on the catheter indwelling record. The indwelling safety rules include patient activity restrictions, catheter use restrictions, mandatory review items, maintenance completion judgment nodes, handover completion judgment nodes, and release judgment conditions. The indwelling stage includes the post-insertion observation stage, routine indwelling maintenance stage, activity or transfer stage, and handover stage. Based on the catheter type, indwelling site, indwelling side, fixation method, maintenance cycle, and current indwelling stage, the rule-determining unit determines the patient activity restriction period, patient activity restriction type, restricted nursing operation type, mandatory review items, maintenance completion judgment nodes, handover completion judgment nodes, release judgment conditions, and associated time windows corresponding to the current catheter indwelling status, and forms the corresponding indwelling safety rules accordingly. With this setting, the risk assessment and review requirements for different catheter indwelling statuses have clear corresponding basis, avoiding subsequent processing from relying solely on a single time node or a single record result.

[0010] The bedside information acquisition terminal includes a device interface unit and a bedside data entry unit. The device interface unit is used to acquire the operating status data of infusion equipment or injection equipment, including infusion start information, infusion pause information, and equipment alarm information. The bedside data entry unit is used to enter patient activity status information, local indwelling status information, nursing treatment status information, and supplementary catheter usage status information.

[0011] The patient activity status information includes information on turning over, getting out of bed, transfer, and movement of the limb on the catheter insertion side; the local indwelling status information includes information on the external segment of the catheter, the fixation area, the puncture site, and the dressing; the nursing care status information includes maintenance operation information, abnormal handling information, and handover operation information; and the supplementary catheter usage status information includes flushing information, sealing information, and interface opening and closing information. Thus, the system can simultaneously obtain equipment operation data and bedside observation records, providing a complete data source for key statuses related to catheter placement.

[0012] The status association unit is used to generate patient activity status records, catheter use status records, local indwelling status records, and nursing treatment status records based on bedside status information, and compares each status record with the indwelling safety rules within the associated time window; When the comparison results meet the preset risk establishment conditions, the status association unit generates a corresponding risk handling event. The risk establishment conditions include the following situations: the patient's activity status violates the patient activity restriction conditions, and is accompanied by changes in catheter usage status or abnormal local indwelling status within the associated time window; the catheter usage status violates the catheter usage restriction conditions, and is accompanied by abnormal local indwelling status within the associated time window; before entering the nursing handover process, there are pending matters that have not reached the maintenance completion judgment node, or there are unresolved nursing operation completion confirmation request processing restrictions. After adopting the above association judgment method, the system does not directly handle a single abnormal status, but judges whether a risk matter that needs to be prioritized is formed based on the current indwelling stage and the sequential relationship between status changes, so that the risk identification results correspond to the actual nursing scenario.

[0013] The review control unit generates an instant review task sequence based on risk management events and sends it to the nursing interaction terminal. This sequence guides nursing staff to complete the corresponding review for the current risk. Different risk management events correspond to different review contents. When the risk management event is an activity-related risk management event, the instant review task sequence includes catheter fixation status review, puncture site review, and lumen patency status review. When the risk management event is a catheter use-related risk management event, the sequence includes lumen patency status review, catheter use continuity status review, and puncture site review. When the risk management event is a handover-related risk management event, the sequence includes catheter fixation status review and catheter use continuity status review. This configuration ensures that the review content aligns with the source of the risk, avoiding the use of the same review path for different risk matters.

[0014] The continuous status verification task for catheter use is used to determine whether the current catheter is in a state that allows continued use based on infusion start information, infusion pause information, equipment alarm information, and supplementary catheter use status information. The state that allows continued use means that there are no unresolved equipment alarms and no flushing information, sealing information, or interface opening / closing information that conflict with the catheter use restrictions. By using both the equipment operation status and bedside supplementary records as the basis for judgment, the catheter use status judgment can be more complete.

[0015] The review control unit is also used to control the nursing interaction terminal not to process nursing operation completion confirmation requests corresponding to the current risk management event when the mandatory review items in the immediate review task sequence are not completed; and to control the nursing interaction terminal to resume processing the corresponding nursing operation completion confirmation requests after the mandatory review items are completed and the release judgment conditions are met.

[0016] The nursing procedure completion confirmation requests include infusion initiation completion confirmation requests, patient transfer completion confirmation requests, and nursing handover completion confirmation requests. Therefore, when a risk item has not been properly reviewed, the corresponding nursing procedure cannot be confirmed as completed. Only after the review is completed and the release criteria are met can the relevant nursing procedure proceed to completion confirmation. This ensures that the nursing procedure completion confirmation is consistent with the review progress and avoids proceeding to the next nursing stage before the risk item has been properly addressed.

[0017] After the immediate review task sequence is completed, the review control unit continues to determine whether there are still items that have not reached the maintenance completion judgment node or the handover completion judgment node. If so, a continuation confirmation task sequence is generated and sent to the nursing interaction terminal. The continuation confirmation task sequence includes one or both of the maintenance completion confirmation task and the handover completion confirmation task. When the local indwelling status information is insufficient to support the determination of the immediate review task sequence, the review control unit sends a local status supplementation instruction to the nursing interaction terminal and determines the task content or execution order in the immediate review task sequence based on the returned supplementation results. The local status supplementation instruction corresponds to one or more of the catheter external segment status, fixation area status, puncture site status, and dressing status. In this way, when the initial status information is insufficient, the system can first supplement the necessary status and then determine the review content, avoiding inaccurate review task configuration due to missing information.

[0018] The handover and continuation unit is used to write incomplete continuation confirmation task sequences and unresolved nursing operation completion confirmation request processing restrictions into the continuation record when a nursing handover occurs. After the next responsible nursing interaction terminal receives the handover information of the target patient, it calls the continuation record to continue to execute the continuation confirmation task sequence and maintain the corresponding nursing operation completion confirmation request processing restrictions. In this way, incomplete risk matters remain in a continuous processing state after the nursing responsibility personnel change, avoiding the interruption of the risk management chain due to handover.

[0019] In addition, the safety decision-making host is also used to establish trigger records and release records for each risk management event. The trigger record includes the trigger time, trigger reason, and bedside status information at the time of triggering. The release record includes the information of the personnel performing the action, the completion status of the immediate review task sequence, the execution status of the continued confirmation task sequence, and the release time of the corresponding nursing operation completion confirmation request processing restriction. The safety decision-making host verifies the completion status of the corresponding risk management event based on the trigger record and release record to retain a complete record of the risk management process.

[0020] Compared to existing catheter placement care methods that rely on decentralized manual judgment and post-event record-keeping, this invention integrates catheter placement records, bedside status information, risk management events, real-time review task sequences, nursing operation completion confirmation requests, and handover continuation mechanisms into a single processing chain. This creates a continuous correspondence between risk identification, review execution, completion confirmation, and handover continuation. Thus, after a risk is identified, the system first organizes necessary reviews before deciding whether to allow the relevant nursing operation to proceed to completion confirmation. Furthermore, it retains processing restrictions for unfinished items after nursing handover, thereby ensuring consistency between the catheter placement safety management process and the nursing treatment process.

[0021] In this invention, the safety decision-making host first establishes a catheter placement file for the target patient. The catheter placement file includes catheter type, placement site, placement side, fixation method, maintenance cycle, placement stage, and handover review items. After the basic information, maintenance requirements, and handover requirements related to catheter placement are uniformly incorporated into the catheter placement file, the determination of placement safety rules, the judgment of risk management events, and the generation of review tasks are all based on the same data foundation, thereby avoiding inconsistencies in treatment standards caused by different nursing links making independent judgments based on their own records.

[0022] The bedside information acquisition terminal includes a device interface unit and a bedside data entry unit; the device interface unit is used to acquire the operating status data of infusion equipment or injection equipment, including infusion start information, infusion pause information and equipment alarm information; the bedside data entry unit is used to enter patient activity status information, local indwelling status information, nursing treatment status information and supplementary catheter usage status information.

[0023] The patient activity status information includes information on turning over, getting out of bed, transfer, and movement of the limb on the catheter insertion side; the local indwelling status information includes information on the external segment of the catheter, the status of the fixation area, the status of the puncture site, and the dressing status; the nursing care status information includes maintenance operation information, abnormal handling information, and handover operation information; and the supplementary catheter usage status information includes flushing information, sealing information, and interface opening and closing information. Thus, the system can acquire both the operational status data of infusion or injection equipment and the local indwelling status and nursing care status observed by nurses at the bedside, providing a continuous data source for key statuses during catheter indwelling.

[0024] After establishing a catheter placement record, the safety decision-making system determines the placement safety rules corresponding to the current placement stage based on the catheter placement record. The placement stage includes the post-placement observation stage, the routine placement maintenance stage, the activity or transfer stage, and the handover stage. Based on the catheter type, placement site, placement side, fixation method, maintenance cycle, and current placement stage, the safety decision-making system determines the patient activity restriction period, patient activity restriction type, restricted nursing operation type, mandatory review items, maintenance completion judgment node, handover completion judgment node, release judgment conditions, and associated time windows corresponding to the current catheter placement status, and forms placement safety rules accordingly. In this way, the risk assessment basis, review requirements, and completion confirmation conditions have a clear correspondence in different catheter placement statuses, avoiding the use of the same treatment standard in different stages, which would affect the risk assessment results.

[0025] After obtaining bedside status information, the safety decision-making host generates patient activity status records, catheter usage status records, local indwelling status records, and nursing treatment status records based on the bedside status information. Within a relevant time window, each status record is compared with the indwelling safety rules. When the comparison result meets the preset risk establishment conditions, the safety decision-making host generates a corresponding risk treatment event. The risk establishment conditions include the following situations: the patient's activity status violates the patient activity restriction conditions, and this is accompanied by a change in catheter usage status or an abnormal local indwelling status within the relevant time window; the catheter usage status violates the catheter usage restriction conditions, and this is accompanied by an abnormal local indwelling status within the relevant time window; before entering the nursing handover process, there are pending matters that have not reached the maintenance completion judgment node, or there are unresolved processing restrictions on nursing operation completion confirmation requests. Using the above judgment method, the system does not directly trigger treatment based on a single abnormal status, but rather forms risk treatment events based on the sequential and superimposed relationships between states. Therefore, the resulting risk judgment results can correspond to the actual nursing scenario.

[0026] Once a risk management event is identified, the safety decision-making system generates a corresponding sequence of immediate review tasks based on the source of the risk. Risk management events include activity-related risk management events, catheter use-related risk management events, and handover-related risk management events. For activity-related risk management events, the immediate review task sequence includes catheter fixation status review, puncture site review, and lumen patency review. For catheter use-related risk management events, the immediate review task sequence includes lumen patency review, catheter use continuity review, and puncture site review. For handover-related risk management events, the immediate review task sequence includes catheter fixation status review and catheter use continuity review. In this way, different risk sources correspond to different review contents, allowing nursing staff to conduct targeted reviews based on the current risk, avoiding a disconnect between review content and the risk source.

[0027] The continuous catheter usage status verification task is used to determine whether the current catheter is in a state where continued use is permitted based on infusion start information, infusion pause information, equipment alarm information, and supplementary catheter usage status information. The state where continued use is permitted meets the following conditions: there are no unresolved equipment alarms, and there are no flushing information, sealing information, or interface opening / closing information that conflict with the catheter usage restrictions. By combining the equipment operating status with the supplementary catheter usage status information, the determination of the catheter usage status no longer relies solely on equipment alarm information or a single bedside record, thus making the determination result more consistent with the actual usage situation.

[0028] The nursing interactive terminal receives the review tasks corresponding to the real-time review task sequence and enters the review results. After the nursing staff completes the corresponding review, the nursing interactive terminal initiates a nursing operation completion confirmation request. The nursing operation completion confirmation request includes an infusion start completion confirmation request, a patient transfer completion confirmation request, and a nursing handover completion confirmation request. When the safety decision host determines that the mandatory review item corresponding to the current risk management event has not been completed, it imposes a processing restriction on the corresponding nursing operation completion confirmation request. When the mandatory review item is completed and the release judgment condition is met, the processing restriction on the corresponding nursing operation completion confirmation request is lifted. In this way, the completion confirmation of nursing operations is consistent with the review progress of risk items, and risk items that have not completed the necessary review will not directly enter the next nursing stage.

[0029] After the immediate review task sequence is completed, the safety decision host continues to determine whether there are still matters that have not reached the maintenance completion judgment node or the handover completion judgment node. If such matters exist, a continuation confirmation task sequence is generated and sent to the nursing interaction terminal. The continuation confirmation task sequence includes one or both of the maintenance completion confirmation task and the handover completion confirmation task. By continuing to check the maintenance completion status and handover completion status after the immediate review, the system can connect the immediate handling of the current risk matters with the subsequent completion confirmation, avoiding the existence of unclosed subsequent matters after the immediate review is completed.

[0030] When the existing local indwelling status information is insufficient to support the determination of the immediate review task sequence, the safety decision host sends a local status supplementation instruction to the nursing interaction terminal, and determines the task content or execution order in the immediate review task sequence based on the returned supplementation results; the local status supplementation instruction corresponds to one or more of the following: catheter external segment status, fixation area status, puncture site status, and dressing status; in this way, when the local indwelling status information is insufficient, the system first supplements the necessary status, and then determines the review content, thereby improving the accuracy of the review task configuration.

[0031] Based on the above processing, the catheter placement file, bedside status information, placement safety rules, risk management events, immediate review task sequence, nursing operation completion confirmation request and continuation confirmation task sequence form a sequential processing link; this processing link enables risk identification, review execution, completion confirmation and subsequent continuation to be coordinated under the same logic, thereby making the catheter placement safety management process consistent with the nursing treatment process.

[0032] The beneficial effects of this invention are as follows: 1. This invention establishes catheter placement files and determines corresponding placement safety rules based on catheter type, placement site, fixation method, maintenance cycle, and placement stage. This ensures that patient activity restrictions, catheter usage restrictions, maintenance completion judgment nodes, and handover completion judgment nodes correspond one-to-one with the current catheter placement status. Simultaneously, it correlates and judges the patient activity status, catheter usage status, local placement status, and nursing treatment status obtained from the bedside information collection terminal. This allows status information scattered across different nursing stages to be compared on the same basis, reducing the need to make judgments based solely on a single bedside observation or single device information, and improving the timeliness and consistency of risk identification.

[0033] 2. This invention categorizes risk management events into activity-related risk management events, catheter use-related risk management events, and handover-related risk management events, and generates corresponding real-time review task sequences for different risk management events. This allows for targeted reviews of catheter fixation status, puncture site, lumen patency, and continuous catheter use status, all centered around the current source of risk. Simultaneously, when mandatory review items are not completed, processing restrictions are imposed on the corresponding nursing procedure completion confirmation request. These restrictions are lifted only after the release criteria are met, ensuring that the nursing procedure completion confirmation is aligned with the risk management progress and reducing the likelihood of a risk entering subsequent nursing stages before its review is completed.

[0034] 3. This invention, by continuing to assess maintenance and handover completion status after the immediate review task sequence is completed, and generating a continuation confirmation task sequence when there are incomplete items, ensures continuous connection between the immediate handling of risk items and subsequent confirmation. Simultaneously, it triggers local status supplementation when local indwelling status information is insufficient, and writes incomplete continuation confirmation task sequences and unresolved processing restrictions into the continuation record when nursing handover occurs. This allows review tasks in cases of missing information to still obtain supplementary evidence, and enables incomplete items after a change in nursing responsibility to continue along the original processing chain, improving the continuity and integrity of the catheter indwelling safety management process. Attached Figure Description

[0035] Figure 1 This is a flowchart for the risk handling event determination and real-time review task generation of the present invention. Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1 As shown in the figure, this embodiment of the invention provides a safety management and nursing decision support system for indwelling catheters in vascular interventional therapy. The system includes a bedside information acquisition terminal, a nursing interaction terminal, and a safety decision host.

[0038] The bedside information collection terminal connects to the safety decision-making host to collect bedside status information related to the indwelling catheter of the target patient and send it to the safety decision-making host. The nursing interaction terminal connects to the safety decision-making host to receive review tasks, enter review results, and initiate corresponding nursing operation completion confirmation requests when nursing staff intend to confirm the completion of a nursing operation. The safety decision-making host is used to correlate catheter placement records, bedside status information, and review results, and controls the processing status of nursing operation completion confirmation requests by the nursing interaction terminal based on the processing results.

[0039] In this embodiment, the safety decision-making host includes a file creation unit, a rule determination unit, a status association unit, a review and control unit, and a handover and continuation unit. The file creation unit is used to create a catheter placement file corresponding to the target patient. The catheter placement file records the catheter type, placement site, placement side, fixation method, maintenance cycle, placement stage, and handover and review items. The rule determination unit is connected to the file creation unit and is used to determine the placement safety rules corresponding to the current placement stage based on the catheter placement file. The placement safety rules include patient activity restrictions, catheter use restrictions, mandatory review items, maintenance completion judgment nodes, handover completion judgment nodes, release judgment conditions, and associated time windows.

[0040] After the bedside information acquisition terminal collects bedside status information, the status association unit generates patient activity status records, catheter usage status records, local placement status records, and nursing treatment status records based on the bedside status information. It then compares each status record within an associated time window according to the placement safety rules output by the rule determination unit. When the comparison result meets the preset risk establishment conditions, the status association unit generates a corresponding risk treatment event. The review control unit generates an instant review task sequence based on the risk treatment event and sends it to the nursing interaction terminal. After receiving the review tasks corresponding to the instant review task sequence, the nursing interaction terminal allows nursing staff to complete the corresponding reviews and enter the review results. The review control unit determines whether the mandatory review items corresponding to the current risk treatment event have been completed based on the review results. When the mandatory review items are not completed, processing restrictions are imposed on the corresponding nursing operation completion confirmation request; when the mandatory review items are completed and the release judgment conditions are met, the processing restrictions on the corresponding nursing operation completion confirmation request are lifted.

[0041] After the immediate review task sequence is completed, the review control unit continues to determine whether there are still any items that have not reached the maintenance completion judgment node or the handover completion judgment node. If such items exist, a continuation confirmation task sequence is generated and sent to the nursing interaction terminal. The handover continuation unit is connected to the review control unit and is used to write incomplete continuation confirmation task sequences and unresolved processing restrictions on nursing operation completion confirmation requests into the continuation record when a nursing handover occurs. When the next responsible nursing interaction terminal receives the target patient handover information, the handover continuation unit calls the continuation record to continue the execution of the corresponding continuation confirmation task sequence and maintain the corresponding processing restrictions.

[0042] This embodiment provides a safety management and nursing decision support system for indwelling catheters used in vascular interventional therapy. The system includes a bedside information acquisition terminal, a nursing interaction terminal, and a safety decision host. The bedside information acquisition terminal is connected to the safety decision host and is used to collect bedside status information related to the indwelling catheter of the target patient and send it to the safety decision host. The nursing interaction terminal is connected to the safety decision host and is used to receive review tasks issued by the safety decision host, enter review results, and initiate corresponding nursing operation completion confirmation requests when nursing staff intend to confirm the completion of corresponding nursing operations. The safety decision host is used to perform correlation processing on catheter indwelling records, bedside status information, and review results, and controls the processing status of nursing operation completion confirmation requests on the nursing interaction terminal based on the processing results.

[0043] In this embodiment, the safety decision host includes a file creation unit, a rule determination unit, a status association unit, a review and control unit, and a handover and continuation unit; the file creation unit is used to create a catheter placement file corresponding to the target patient; the catheter placement file records the catheter type, placement site, placement side, fixation method, maintenance cycle, placement stage, and handover and review items.

[0044] Among them, catheter type is used to identify the category of the current indwelling catheter, indwelling site and indwelling side are used to identify the indwelling location of the catheter, fixation method is used to identify the current fixation method of the external segment of the catheter, maintenance cycle is used to identify the maintenance time requirement of the current catheter, indwelling stage is used to identify whether it is currently in the post-catheter observation stage, routine indwelling maintenance stage, activity or transfer stage, or handover stage, and handover verification items are used to identify the items that need to be checked during nursing handover; by establishing catheter indwelling files, the system can provide a unified data foundation for subsequent rule determination, risk assessment, and verification task generation.

[0045] The bedside information acquisition terminal includes a device interface unit and a bedside data entry unit; the device interface unit is used to acquire the operating status data of infusion equipment or injection equipment, including infusion start information, infusion pause information and equipment alarm information; the bedside data entry unit is used to enter patient activity status information, local indwelling status information, nursing treatment status information and supplementary catheter usage status information.

[0046] The patient activity status information includes information on turning over, getting out of bed, transfer, and movement of the limb on the catheter insertion side; the local indwelling status information includes information on the external segment of the catheter, the status of the fixation area, the status of the puncture site, and the status of dressing; the nursing care status information includes maintenance operation information, abnormal handling information, and handover operation information; the supplementary catheter usage status information includes flushing information, sealing information, and interface opening and closing information; in specific applications, the device interface unit continuously receives the operating status data output by the infusion or injection device, and the bedside data entry unit is used by nursing staff to enter the corresponding information after observing at the bedside or completing the corresponding nursing care procedures.

[0047] Therefore, the system can acquire not only the equipment operating status, but also the local status of the catheter and the status of nursing care, so that the status judgment has a continuous data source.

[0048] The rule determination unit is connected to the file establishment unit and is used to determine the indwelling safety rules corresponding to the current indwelling stage based on the catheter indwelling file. The indwelling safety rules include patient activity restrictions, catheter use restrictions, mandatory review items, maintenance completion judgment nodes, handover completion judgment nodes, release judgment conditions, and associated time windows.

[0049] Specifically, the rule-determining unit generates, based on catheter type, placement site, placement side, fixation method, maintenance cycle, and current indwelling stage, patient activity restriction period, patient activity restriction type, restricted nursing operation type, mandatory review items, maintenance completion judgment node, handover completion judgment node, release judgment conditions, and associated time window corresponding to the current catheter indwelling status.

[0050] Among them, the maintenance completion judgment node and the handover completion judgment node are used to determine whether the corresponding maintenance items and handover items have met the completion conditions, respectively; the release judgment condition is used to determine whether to lift the processing restriction on the nursing operation completion confirmation request; the associated time window is used to limit the time range used when the status is associated; after this setting, the risk judgment basis and review requirements for different catheter indwelling statuses have a clear correspondence.

[0051] The status association unit is used to generate patient activity status records, catheter usage status records, local indwelling status records, and nursing treatment status records based on bedside status information. It then compares each status record within an associated time window based on the indwelling safety rules output by the rule determination unit. When the comparison result meets preset risk establishment conditions, the status association unit generates a corresponding risk treatment event. These preset risk establishment conditions include the following: the patient's activity status violates patient activity restrictions, and this is accompanied by changes in catheter usage status or abnormal local indwelling status within the associated time window; the catheter usage status violates catheter usage restrictions, and this is accompanied by abnormal local indwelling status within the associated time window; before entering the nursing handover process, there are pending matters that have not reached the maintenance completion judgment node, or there are unresolved processing restrictions on nursing operation completion confirmation requests. Through the above processing, the system does not directly trigger treatment based on a single status, but rather comprehensively judges the patient's activity status, catheter usage status, local indwelling status, and nursing treatment status within the same time frame to generate a risk treatment event corresponding to the actual nursing scenario.

[0052] After a risk management event is generated in the status association unit, the review and control unit generates a corresponding real-time review task sequence based on the risk management event and sends it to the nursing interaction terminal. Risk management events include activity-related risk management events, catheter use-related risk management events, and handover-related risk management events. For activity-related risk management events, the real-time review task sequence includes catheter fixation status review task, puncture site review task, and lumen patency status review task. For catheter use-related risk management events, the real-time review task sequence includes lumen patency status review task, catheter use continuity status review task, and puncture site review task. For handover-related risk management events, the real-time review task sequence includes catheter fixation status review task and catheter use continuity status review task.

[0053] Nursing staff complete the corresponding reviews based on the instant review tasks displayed on the nursing interactive terminal and enter the review results into the nursing interactive terminal. By assigning different types of risk management events to different instant review task sequences, the system enables the review content to directly revolve around the current source of risk.

[0054] The continuous status verification task for catheter use is used to determine whether the current catheter meets the conditions for continued use based on infusion start information, infusion pause information, equipment alarm information and supplementary catheter use status information. Meeting the conditions for continued use means that there are no unresolved equipment alarms and no flushing information, sealing information or interface opening / closing information that conflict with the catheter use restrictions.

[0055] In practice, when the verification control unit performs the continuous status verification task for catheter use, it first reads the infusion start information, infusion pause information, and equipment alarm information provided by the equipment interface unit, and then reads the flushing information, sealing information, and interface opening / closing information provided by the bedside data entry unit. The above information is then compared with the current catheter use restrictions. If the comparison result shows that there are no unresolved equipment alarms and no flushing, sealing, or interface opening / closing operations that conflict with the current catheter use restrictions, the current catheter is determined to meet the conditions for continued use. Otherwise, the current catheter is determined not to meet the conditions for continued use.

[0056] After nursing staff complete the immediate review task, the nursing interaction terminal can initiate a nursing operation completion confirmation request for the nursing operation to be completed; the nursing operation completion confirmation request includes an infusion start completion confirmation request, a patient transfer completion confirmation request, and a nursing handover completion confirmation request; the review control unit determines whether to impose processing restrictions on the corresponding nursing operation completion confirmation request based on the current risk management event and the completion status of its corresponding mandatory review items.

[0057] When the mandatory review item corresponding to the current risk management event has not been completed, the review control unit returns a confirmation prohibition flag and an incomplete item prompt message to the nursing interaction terminal. The nursing interaction terminal keeps the nursing operation completion confirmation request in a failed state accordingly. When the mandatory review item has been completed and the release judgment conditions are met, the review control unit removes the processing restriction on the corresponding nursing operation completion confirmation request, and the nursing interaction terminal resumes normal processing of the nursing operation completion confirmation request. In this way, the completion confirmation of nursing operations can be kept in line with the progress of risk management.

[0058] After the immediate review task sequence is completed, the review control unit continues to determine whether there are still items that have not reached the maintenance completion judgment node or the handover completion judgment node. If so, a continuation confirmation task sequence is generated and sent to the nursing interaction terminal. The continuation confirmation task sequence includes one or both of the maintenance completion confirmation task and the handover completion confirmation task. Specifically, when the immediate review task sequence has been completed but a certain maintenance operation has not yet reached the maintenance completion judgment node, the review control unit generates the corresponding maintenance completion confirmation task; when the immediate review task sequence has been completed but the handover-related verification items have not yet reached the handover completion judgment node, the review control unit generates the corresponding handover completion confirmation task; when both types of items exist simultaneously, the review control unit generates the corresponding maintenance completion confirmation task and the handover completion confirmation task simultaneously.

[0059] When the local indwelling status information is insufficient to determine the immediate review task sequence, the review control unit sends a local status supplementation instruction to the nursing interaction terminal, and determines the task content or execution order in the immediate review task sequence based on the returned supplementation results. The local status supplementation instruction corresponds to one or more of the following: catheter external segment status, fixation area status, puncture site status, and dressing status.

[0060] Specifically, when the status association unit only obtains changes in the patient's activity status or catheter usage status, but does not obtain sufficient local indwelling status information to support the determination of the immediate review task sequence, the review control unit calls the local status supplementation instruction to prompt the nursing staff to supplement the missing content in the status of the catheter's external segment, fixation area, puncture site, or dressing status; after the nursing staff completes the supplementation and the nursing interaction terminal returns the supplementation results, the review control unit then determines the specific task content or execution order in the immediate review task sequence based on the supplementation results.

[0061] The handover and continuation unit is connected to the review and control unit. When a nursing handover occurs, it writes the incomplete continuation confirmation task sequence and the unresolved processing restrictions on nursing operation completion confirmation requests into the continuation record. When the next responsible nursing interaction terminal receives the target patient handover information, the handover and continuation unit calls the continuation record to ensure that the corresponding continuation confirmation task continues to be displayed on the next responsible nursing interaction terminal and maintains the processing restrictions on the corresponding nursing operation completion confirmation requests.

[0062] If there are still unfinished maintenance completion confirmation tasks, unfinished handover completion confirmation tasks, or unresolved nursing operation completion confirmation request processing restrictions at the time of nursing handover, all of the above will be written into the continuation record and will continue to be effective after the next responsible nursing interaction terminal receives the target patient handover information.

[0063] Based on the above process, the establishment of catheter placement records, the determination of placement safety rules, the judgment of bedside status association, the formation of risk management events, the generation of immediate review task sequences, the processing and restriction control of nursing operation completion confirmation requests, the generation of continuation confirmation task sequences, and the handover and continuation processing constitute a continuous process around catheter placement safety management, so that the catheter placement safety management process and the nursing treatment process maintain a corresponding relationship.
