[0002] In modern medicine, infusion therapy is extremely common and is an important route of drug administration. However, there are many problems with the traditional infusion process. Nurses need to frequently travel between the ward and the nurse station to check the progress of the infusion, which is a heavy workload and inefficient. At the same time, manual monitoring is difficult to ensure the accuracy of the infusion speed. Too fast or too slow a drip rate may affect the treatment effect and even endanger the safety of the patient, such as causing an increased burden on the circulatory system or the drug failing to take effect in time. Moreover, during the infusion process, patients are often nervous because they are worried about problems such as blood return after the infusion, and they cannot rest at ease, resulting in a poor medical experience.

[0003] In the traditional infusion management process, the issuance of doctor's orders, review, medication verification, execution verification, and infusion inspections are mostly based on manual recording and operation, and the information is scattered and prone to errors. It is difficult to achieve automatic flow and accurate traceability of information. Once a problem occurs, it is difficult to quickly locate and find out the cause. For example, when verifying the patient's identity, it is easy to be negligent if only the wristband information is manually verified. If an incorrect infusion occurs, it is impossible to know the responsible link and the relevant responsible person in time, which is not conducive to the control and improvement of medical quality.

[0027] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0028] Embodiment 1: As shown in the attached Figure 1 To Attachment Figure 6 As shown: The present invention provides a fully closed-loop intelligent infusion management system, including an intelligent infusion monitor, a Bluetooth Internet of Things hub, a closed-loop infusion server and a display terminal;

[0029] The intelligent infusion monitor has a built-in ultra-micro gravity sensor to monitor the weight change of the infusion device in real time, use algorithms to process the drip rate and remaining liquid volume, automatically identify the infusion status, and transmit liquid data and infusion status to the Bluetooth Internet of Things hub via Bluetooth; in case of communication abnormalities, the data is temporarily stored and uploaded for recovery;

[0030] The intelligent infusion monitor uses the Kalman filter algorithm to filter the remaining weight data collected by the ultra-micro gravity sensor. The algorithm is based on the linear minimum variance estimation theory. By predicting the system state and correcting the measured value, it can effectively remove noise interference in the measurement process, making the data smoother and more stable, and improving the accuracy of the remaining liquid volume calculation. For example, during the infusion process, the sensor measurement value may fluctuate briefly due to environmental vibration or shaking of the infusion bag. The Kalman filter algorithm can dynamically adjust the weight according to the state estimate at the previous moment and the current measurement value to obtain a filtering result that is closer to the true value, thereby providing a reliable data basis for subsequent liquid volume calculations.

[0031] The intelligent infusion monitor uses the time interval measurement method to calculate the infusion drip rate;

[0032] By installing a sensor (infrared sensor or optical sensor) on the infusion tube, the moment when the droplet falls can be accurately detected; the algorithm records the time interval t between two adjacent drops of liquid, and the droplet volume V is known at the same time. d (pre-set or calibrated according to the infusion tube specifications and liquid characteristics);

[0033] According to the formula The time interval is converted into the number of drops per minute, i.e., the drip rate v; this algorithm can accurately reflect the changes in the infusion rate in real time, ensuring the timeliness and accuracy of drip rate monitoring.

[0034] The intelligent infusion monitor calculates the remaining infusion amount based on the relationship between weight difference and density;

[0035] The system pre-stores or identifies the density ρ of the current infusion liquid (different drug solutions have different densities, which can be matched by database or input manually); at the beginning of the infusion, the initial weight W of the infusion bag or bottle is recorded. 0 , at any time t during the infusion process, the current weight W(t) is measured by the sensor;

[0036] According to the formula The liquid volume change V from the initial state to the current moment is calculated to obtain the remaining liquid volume; the algorithm uses the physical relationship between weight and liquid volume to convert weight measurements into intuitive liquid volume information through precise density parameters, providing key quantitative data for infusion management.

[0037] The Bluetooth IoT hub connects the smart infusion monitor and the closed-loop infusion server, integrates and converts the infusion data and infusion status into network signal transmission, selects the best method according to the network environment, monitors the abnormal connection status and alarms. The Blue Bridge can support multiple Bluetooth devices to access the Internet. One Blue Bridge can connect to multiple smart infusion monitors. The infusion monitor transmits the monitored infusion data and infusion status to the Blue Bridge via Bluetooth. The Blue Bridge then transmits the data to the server and other Internet systems via WiFi or wired methods, completing the entire data transmission and sharing.

[0038] The wireless charging pad charges the infusion monitor and automatically calibrates while charging, changing the traditional charging method;

[0039] The closed-loop infusion server receives and processes infusion data and infusion status from the Bluetooth IoT hub, and is responsible for data forwarding, storage, and analysis; determines the infusion status and issues an alarm, manages device information, stores historical data for statistical analysis, and connects and shares with the hospital information system;

[0040] The display terminal can be an NDA, workstation, display screen or PC; it can display the infusion data and infusion status in real time. When the remaining weight is lower than the warning value and the drip rate exceeds the set value, the terminal system page will issue a color alarm to facilitate medical staff to view.

[0041] Infusion data includes: bed number, total weight, infused weight, remaining weight, infusion time, infusion drip rate, and percentage of infusion completed;

[0042] The infusion status includes: all, infusion, infusion paused, infusion stopped, and no infusion; when the infusion is stopped, the infusion volume is lower than the warning value, and the drip rate exceeds the set value, the system page will issue a color alarm.

[0043] The display terminal displays the infusion data and infusion status in real time. When the remaining weight is lower than the warning value and the dripping rate exceeds the set value, the terminal system page will issue a color alarm.

[0044] It also includes a wireless charging pad; the wireless charging pad charges the infusion monitor and automatically calibrates during charging, changing the traditional charging method.

[0045] The system also has the functions of infusion inspection, intelligent reminder, equipment management, big data support for clinical practice, medication information query and drug analysis.

[0046] Infusion inspection: The system continuously monitors data such as infusion drip rate and remaining liquid volume, and checks the infusion process in real time. It supports scanning bottle labels to enter infusion inspection content with one click, and automatically generates infusion inspection forms to improve infusion inspection efficiency.

[0047] Intelligent reminder: reminder of doctor's order status change (newly issued, newly reviewed, newly stopped), skin test observation reminder, reminder before infusion doctor's order execution, reminder of successful and failed infusion doctor's order execution, and abnormal infusion inspection, such as abnormal infusion drip rate reminder and remaining liquid volume reminder. The reminder switch and mode can be set. After setting, the system will send alarm message reminder according to the set mode;

[0048] Equipment management: add, delete, query, and modify the information and parameters of infusion monitors and Blue Bridge, so that nurses can customize the settings according to the actual usage scenarios;

[0049] Big data support for clinical practice: Figure 3 As shown, the terminal can perform infusion and workload statistics, generate trend charts to assist department management, and facilitate personnel arrangements and work regulation in departments;

[0050] Medication information query: Query drug infusion status on PC to assist clinical decision-making.

[0051] Combine patient vital signs for drug analysis: Mobile terminal combines vital signs with infusion drug analysis.

[0052] The display terminal can also perform refined statistical inquiries and message management statistical inquiries. It supports inquiries on the infusion statistics of a certain drug within a certain period of time, department range, or specified patient. It includes single-use drug dosage, multiple cumulative use records, patient information, abnormal conditions during use, etc., which facilitates drug analysis and assists clinical decision-making.

[0053] The infusion workflow of the inpatient department is as follows:

[0054] ①The doctor issues medical advice on the HIS;

[0055] ② The nurse reviews the doctor's orders on the mobile terminal or workstation PC;

[0056] ③Pharmacists review and dispense medicines;

[0057] ④ The intravenous preparation center or department prepares the solution;

[0058] ⑤ The nurse scans the patient's barcode and the infusion bag barcode at the bedside to execute the doctor's order;

[0059] ⑥ Start the infusion monitor to monitor the infusion drip rate and remaining liquid volume, and upload the monitoring data to the server in real time;

[0060] ⑦ Real-time alarm for abnormal infusion situations, medical staff can understand the patient's infusion situation anywhere.

[0061] ⑧End the infusion and synchronize the execution records to the HIS system.

[0062] Safety during infusion has always troubled nurses and patients. After using the infusion monitoring system, once the drip rate is too fast, too slow or even abnormally stopped, the monitoring station will issue an alarm to remind the nurse to check and deal with it to ensure the safety of infusion. In addition, when the infusion is about to be completed, the system will also send a reminder to avoid adverse events such as blood return.

[0063] Using the intelligent infusion monitoring and management system, nurses can review and execute patients' medical orders at the bedside. The entire infusion process is monitored by the system, which mainly improves work efficiency in three aspects: reducing the number of nurses' round trips, arranging work scientifically, and reducing the writing of nursing documents.

[0064] With a similar number of patients, the frequency of nurses entering and leaving the ward within 7 days was counted when the infusion monitoring system was not used and when it was used. The results showed that the frequency of entry and exit dropped from 108 people / day to 56 people / day, a decrease of nearly 50%, reducing the number of times nurses traveled back and forth between the workstation and the patient ward.

[0065] The infusion status of all patients can be understood through smart mobile terminals / display terminals / TVs. When the drip rate is abnormal or the infusion is about to be completed, the system can provide accurate reminders to nurses. For example, in the infusion timeline, the bed number with a remaining liquid volume of 5mL is displayed at a lower position than the bed number with a remaining liquid volume of 10mL. The nurse can then understand which patient will finish the infusion the fastest and is the most urgent, and thus determine the priority of treatment. This completely changes the original hectic scene and avoids alarm fatigue and emotional problems caused by a large number of false alarms.

[0066] The infusion monitoring system is seamlessly connected with in-hospital information portals such as HIS and mobile handheld terminals such as PDA, realizing the automatic flow of a large amount of documents such as patient information, medical order information, infusion records, etc. For example, the infusion drip rate can be automatically filled in the infusion inspection form, greatly reducing the work of nurses copying, checking, and statistics.

[0067] The infusion system can effectively improve the patient's medical experience and increase patient satisfaction. During the infusion process, the patient can rest at ease and does not need to pay attention to the infusion situation all the time. When the infusion is about to be completed, the nurse will appear as soon as the patient finishes the infusion, and the patient does not need to ring the bell to call. The service has changed from passive to active, and the patient experience is better. In addition, the ordinary ward is as quiet as the VIP ward. According to statistics, the number of bell rings in the ward has decreased by 87.3%, the number of patient complaints caused by infusion therapy and related care has decreased by 80%, and the overall satisfaction of patients and their families with nursing services is 96%.

[0068] The infusion monitoring system can assist medical staff in data analysis and clinical research. The system can perform infusion statistics and workload statistics, and support automatic generation of trend charts, which is convenient for departments to arrange personnel and control work; combined with bedside vital signs monitoring equipment, it can obtain the patient's body temperature, blood pressure, pulse, respiration, heart rate, blood oxygen and pain, etc., and analyze it in combination with infusion drugs, establish a new intelligent early warning mechanism, and accurately evaluate the efficacy of infusion and drugs.

[0069] Example 2: A is admitted to the hospital due to pneumonia. The doctor issues an infusion order for A on the HIS side, which includes antibiotics, expectorants and other drugs. The order includes detailed information such as drug name, dosage, infusion frequency, and infusion speed.

[0070] Nurse C receives the doctor's order reminder on the mobile nursing terminal (NDA) and reviews it. At the same time, the system automatically sends the doctor's order information to the pharmacist workstation; pharmacist B reviews the doctor's order on the PC and sends the medicine to the intravenous preparation center after confirming that the drug combination is correct.

[0071] The staff at the intravenous preparation center prepares the solution according to the doctor's instructions and attaches a label with a QR code to the prepared infusion bag. The label contains patient information, drug information, infusion batch, etc.

[0072] Nurse C pushes the treatment cart to Ward A and uses NDA to scan the barcode on A's wristband and the QR code on the infusion bag at the bedside to execute the doctor's order. At this time, the system automatically records the execution time and operator information.

[0073] C hangs up the infusion bag and starts the smart infusion monitor. The monitor starts to monitor the infusion drip rate and the remaining liquid volume in real time. The data is transmitted to the Bluetooth IoT hub via Bluetooth, and then transmitted to the closed-loop infusion server by the hub. Finally, the infusion information is displayed in real time on the nurse station display, C's NDA, and the doctor's office PC (display terminal), including bed number "bed 305", total weight "250ml", infused weight "50ml", remaining weight "200ml", infused time "15 minutes", infusion drip rate "50 drops / minute", infusion percentage status "20%", etc. The infusion status is displayed as "infusion in progress".

[0074] During the infusion process, the system continuously monitors; when A turns over, the infusion tube is slightly pulled, causing the infusion drip rate to increase temporarily; the intelligent infusion monitor immediately detects the change in drip rate and uploads the data; the closed-loop infusion server determines the drip rate abnormality based on the preset algorithm, and pops up an alarm on the nurse station display and C's NDA, showing "Bed 305 A's infusion drip rate is too fast, the current drip rate is 65 drops / minute (the normal range is set to 40-60 drops / minute)", and sends a voice reminder "Bed 305's infusion drip rate is abnormal, please check". After hearing the reminder, C rushed to the ward in time to adjust the drip rate.

[0075] As the infusion progresses, the remaining liquid volume gradually decreases. When the remaining weight is lower than 10ml (warning value), the system will issue an alarm on the display terminal again, and A's infusion information on the page will turn red and flash, reminding the nurse to prepare to remove the needle or change the liquid. After seeing the alarm, C quickly prepares a new infusion bag and replaces it for A at the appropriate time.

[0076] During the inspection, use NDA to scan the QR code on the infusion bag and enter the infusion inspection content with one click, such as "the patient has no discomfort and there is no redness or swelling at the infusion site." The system automatically saves the inspection record and generates an infusion inspection form based on the input information.

[0077] Based on the changes in A's condition, the doctor modified the infusion order on the HIS and adjusted the dosage of one of the drugs. The system automatically pushed a reminder of the order change to C's NDA, including "Newly reviewed order: Bed 305 A, the dosage of [drug name] is adjusted to [new dosage], please execute."

[0078] After receiving the reminder, C rechecks and executes the doctor's order, and the system updates the relevant parameters of the infusion monitor to ensure that the infusion is carried out according to the new doctor's order.

[0079] After a few days of treatment, A's condition improved and he completed all the infusion courses. After C finished the infusion operation at the bedside, he confirmed the end of the infusion on the NDA and synchronized the execution record to the HIS system, completing the management of the entire infusion process.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
