Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent infusion drop count monitoring method and device. Background Art

[0002] During traditional infusion processes, medical staff usually rely on visual observation of the dripping of liquid in the infusion bucket to monitor the infusion. This method is not only inefficient, but also prone to inaccurate monitoring due to subjective factors and environmental interference.

[0003] With the development of medical technology, infusion drop count monitoring systems that use infrared transmitters and receivers to detect droplet passing signals have emerged. However, most existing systems of this type do not fully consider the complex factors in the actual infusion environment. For example, when the patient moves the infusion device or the ambient temperature changes, causing the drip bucket to fog up, the infrared signal is easily interfered with, causing the detected droplet passing signal to be abnormal, which in turn affects the accuracy of the drop count. In addition, the shaking of the infusion device may also cause unstable situations such as droplet splashing, further exacerbating monitoring errors. The existence of these problems makes it difficult for traditional infusion drop count monitoring systems to operate stably and accurately in complex and changeable clinical infusion scenarios, posing potential risks to patients' infusion safety and hindering medical staff's refined management and remote monitoring of the infusion process.

[0022] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0023] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0024] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication, and program execution capabilities, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the aforementioned functions, a smart infusion drop count monitoring device, an Internet of Vehicles platform, etc. This embodiment and the following embodiments will be described below using a smart infusion drop count monitoring device as an example.

[0025] Based on this, the embodiment of the present application provides an intelligent infusion drop number monitoring method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the intelligent infusion drop count monitoring method of the present application.

[0026] In this embodiment, the intelligent infusion drop count monitoring method includes steps S10 to S40: Step S10, detecting the droplet passing signal in the infusion drop bucket in real time, and determining the current drop number according to the droplet passing signal; It should be noted that the infusion drip chamber is an important component of the infusion device. It is usually a transparent bucket-shaped container. The liquid in the infusion bottle or infusion bag flows into the drip chamber through the infusion tube. Under the action of gravity, the liquid forms droplets in the drip chamber and falls one by one. By observing the falling speed and number of droplets, the progress and speed of the infusion can be understood. When a droplet falls through a specific detection area of ​​the drip bucket, it blocks or reflects the infrared light emitted by the infrared transmitter, causing the signal received by the infrared receiver to change. This signal change is the droplet passing signal, marking a droplet passing event. The system counts the number of drops by identifying and analyzing these signals. The current drop count is based on the collected droplet passing signal. Through specific algorithms and logical operations, the number of infusion drops at a specific moment or time period is calculated, reflecting the real-time progress of infusion and providing medical staff with accurate infusion status information.

[0027] In a feasible implementation, step S10 includes steps A11 to A12: A11: Detects the droplet passing signal in the infusion dropper through the infrared transmitter and receiver at a preset frequency; It should be noted that the droplet passing signal in the infusion drip bucket is detected in real time, and the current number of drops is determined based on the droplet passing signal; the motion state data of the infusion device is collected in real time, the motion state data is filtered to eliminate noise interference, and the shaking amplitude is determined; when the shaking amplitude exceeds the preset threshold or the droplet passing signal is abnormal, a control instruction is generated to adjust the infusion monitoring state; the current drop count data is uploaded to a cloud server integrated with the hospital information system to achieve remote monitoring, thereby achieving accurate and real-time monitoring of the infusion drop count, effectively reducing detection errors caused by factors such as equipment shaking or drip bucket fogging, improving the accuracy and reliability of infusion monitoring, facilitating medical staff to remotely monitor and manage patients' infusion conditions, and improving the efficiency and quality of medical services.

[0028] A12: Calculate the current number of drops based on the time interval between droplet passing signals.

[0029] It should be noted that the current number of drops is calculated based on the time interval between droplet passing signals. The system accurately records the time point of each droplet passing signal, calculates the adjacent time intervals, and converts it into the current number of drops according to a preset algorithm, thereby determining the real-time drip rate of the infusion.

[0030] It should be understood that this solution is applied to an intelligent infusion drop count monitoring system, including: Drop count detection module: includes an infrared transmitter and receiver, used to detect the droplet passing signal in the infusion droplet bucket in real time; Dynamic compensation module: integrated three-axis gyroscope sensor, used to monitor the motion state of the infusion device. When the shaking amplitude exceeds the preset threshold, Trigger the data filtering mechanism, discard the current drop count data and maintain the historical stable flow rate value; Self-cleaning module: It includes a motor-driven clamping device, which is configured on the outside of the drip bucket and detects signal interference in the drip bucket (such as liquid droplets or mist interference) through a pressure sensor. Trigger the clamping device to periodically squeeze the drip bucket, simulating manual squeezing action to remove mist or attachments; Control unit: connected to the above modules, used to receive sensor signals, execute dynamic compensation algorithms and control the action of the clamping device.

[0031] Step S20: collecting motion state data of the infusion device in real time, filtering the motion state data to eliminate noise interference, and determining the shaking amplitude; It should be understood that the gyroscope sensor used to collect the motion status data of the infusion device is a gyroscope model LIS2DH12TR, with a sensitivity ranging from 1000LSB / g (±2g) to 83LSB / g (+16g) and a bandwidth range of 0.5Hz to 672Hz.

[0032] The data filtering mechanism includes the following steps: Real-time collection of gyroscope angular velocity and acceleration data; Eliminate noise interference through Kalman filtering algorithm; When the shaking amplitude exceeds the threshold for ≥0.5s, it is determined to be effective shaking, the drop count is suspended and an alarm is issued.

[0033] It should be noted that infusion equipment refers to various hardware devices related to the infusion process, including infusion stands, infusion pumps, infusion tubes, and monitoring systems installed on them. In this solution, the focus is on the overall movement of the infusion equipment, as its shaking may affect the drop count monitoring; Motion state data reflects the movement of the infusion device in space, and mainly includes acceleration data and angular velocity data. Acceleration data reflects the linear acceleration changes of the device in all directions, including the acceleration of gravity when stationary and the dynamic acceleration when moving; Angular velocity data describes the angular velocity of the device around different axes, that is, the speed of rotation; Since the collected motion data often contains noise, which may come from electronic noise in the sensor itself, environmental interference (such as electromagnetic interference), or other unrelated vibration sources, filtering processing uses specific algorithms (such as Kalman filtering) to analyze and process the data, removing or reducing noise components, retaining the true motion information, improving the purity and reliability of the data, and making subsequent determination of the shaking amplitude more accurate. Through filtering processing, the influence of noise on the motion state data is reduced or removed, misjudgment or data distortion caused by noise is avoided, and it is ensured that the determination of the shaking amplitude can truly reflect the actual movement of the infusion device.

[0034] Based on the filtered motion state data, data analysis and calculations are used to determine the current level of infusion device vibration, or vibration amplitude. This vibration amplitude is a key indicator of device stability. Excessive vibration amplitude can negatively impact the accuracy of drop count monitoring, necessitating real-time monitoring and assessment.

[0035] In a feasible implementation, step S20 includes steps A21 to A23: A21: Real-time acquisition of motion data of the infusion device, including acceleration and angular velocity data; It should be noted that the real-time acquisition of the infusion device's motion data includes acceleration and angular velocity data. Using high-precision sensors, the system dynamically captures the device's acceleration changes in space (reflecting the device's linear acceleration or deceleration in all directions) and angular velocity data (reflecting the speed of the device's rotation around different axes).

[0036] A22: Use the Kalman filter algorithm to filter the acceleration and angular velocity data to obtain filtered motion state data to eliminate noise interference; It should be noted that the Kalman filter algorithm is used to filter the acceleration and angular velocity data to obtain filtered motion state data to eliminate noise interference. The Kalman filter algorithm is a highly efficient autoregressive filtering algorithm that can process the collected noisy motion state data. Through an iterative process of prediction and update, it can isolate the true and useful signal and remove random interference components, making the data more accurate and smooth.

[0037] A23: Determine the real-time shaking amplitude of the infusion device based on the filtered motion state data.

[0038] It should be noted that the real-time vibration amplitude of the infusion device is determined based on the filtered motion state data. By comprehensively analyzing the processed acceleration and angular velocity data, the vibration amplitude of the infusion device at the current moment is calculated, providing a basis for subsequent determination of whether the threshold has been exceeded.

[0039] Step S30, when the shaking amplitude exceeds a preset threshold or the droplet passing signal is abnormal, generating a control instruction to adjust the infusion monitoring state; It should be noted that the preset threshold is a standard value set in advance based on the normal equipment shaking range during the infusion process and the drop count monitoring accuracy requirements. When the monitored shaking amplitude exceeds this threshold, it indicates that the shaking of the infusion equipment may have a significant impact on the accuracy of the drop count monitoring, and appropriate measures need to be taken to adjust it. Abnormal droplet passing signals refer to droplet passing signals that exhibit characteristics inconsistent with normal infusion patterns, such as abnormal signal intensity fluctuations, irregular time intervals, and discontinuities. These abnormalities may be caused by a variety of factors, such as fogging in the drip chamber causing infrared signal scattering or attenuation, droplet splashing, and infusion tubing blockage or distortion, which can affect the system's normal drop count statistics. When excessive shaking amplitude or abnormal droplet passing signals are detected, the system generates corresponding control instructions based on preset control logic and algorithms. These instructions are used to adjust the operating status of the infusion monitoring system to adapt to the current abnormal situation and ensure the normal operation of the system and the reliability of the data; Adjusting the infusion monitoring status involves changing the infusion monitoring process and method based on control instructions. For example, if the shaking amplitude is excessive, real-time drop count statistics are suspended, and the infusion status is estimated using historical stable flow rate values. If the droplet passing signal is abnormal, the self-cleaning module is activated to remove interfering factors such as mist or attachments in the drip bucket, allowing the monitoring system to provide the most accurate infusion status information possible under abnormal conditions.

[0040] In a feasible implementation, step S30 includes step A31: A31: When the shaking amplitude exceeds the preset threshold, the data filtering mechanism is triggered, the current drop count is paused, and an infusion status prompt is generated based on the historical stable flow rate value.

[0041] It should be noted that when the vibration amplitude exceeds a preset threshold, the data filtering mechanism is triggered, the current drop count is suspended, and an infusion status prompt is generated based on the historical stable flow rate value. When the detected vibration amplitude reaches or exceeds the system's pre-set threshold, the system determines that the vibration at this time may cause a large error in the drop count detection. Therefore, the current drop count is suspended and the infusion status prompt is generated based on the flow rate value recorded during the previous stable infusion phase for medical staff to refer to and remind them to pay attention to the infusion situation.

[0042] Step S40 , uploading the current drop count data to a cloud server integrated with the hospital information system to achieve remote monitoring.

[0043] It should be noted that the system utilizes a wireless transmission module (e.g., one based on Wi-Fi, 4G / 5G, or other wireless communication technologies) to package and organize the current drip count data determined in step S10 and transmit it to a cloud server according to a pre-set data transmission protocol. This cloud server is deeply integrated with the hospital information system (HIS). Medical staff can log in to the HIS through an internal work terminal (e.g., a computer, tablet, or other device) and view the current drip count data for each patient's infusion in real time on the corresponding monitoring interface. This enables remote, real-time monitoring of the infusion process, improving the convenience and timeliness of medical services.

[0044] In practice, in actual hospital wards, this intelligent infusion drop count monitoring system is installed on each patient's IV stand. During the infusion process, the system closely coordinates the aforementioned steps, accurately monitoring the drop count while also keeping an eye on the IV stand's swaying state. If any anomalies are detected, the system promptly adjusts the monitoring strategy and alerts medical staff. Medical staff no longer need to be constantly at the patient's side. By viewing the infusion monitoring section in the hospital information system on a computer at the nurse's station or a handheld mobile nursing terminal, they can obtain real-time information on key information, such as the number of drops infused for all patients. This allows for efficient nursing arrangements and improves the overall quality and efficiency of medical services.

[0045] This embodiment provides an intelligent infusion drop count monitoring method. This method uses a multi-axis gyroscope to monitor the device's motion state in real time. Combined with a filtering algorithm, it distinguishes normal vibration from disturbing vibration, avoiding the misjudgment problem of traditional single sensors. Furthermore, it utilizes a motor-driven clamping device for drip bucket cleaning for the first time. The cleaning effect is verified through both pressure feedback and infrared signals, addressing the industry challenge of fog interference. The method detects droplet passage signals within the drip bucket in real time and determines the current drop count based on these signals. The method also collects motion state data from the infusion device in real time, filters the data to eliminate noise interference, and determines the amplitude of the vibration. When the amplitude exceeds a preset threshold or the droplet passage signal is abnormal, a control instruction is generated to adjust the infusion monitoring state. The method also uploads the current drop count data to a cloud server integrated with the hospital information system for remote monitoring. This method enables accurate, real-time monitoring of the infusion drop count, effectively reducing detection errors caused by factors such as device vibration or drip bucket fogging. This method improves the accuracy and reliability of infusion monitoring, facilitates remote monitoring and management of patients' infusions by medical staff, and enhances the efficiency and quality of medical services.

[0046] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 2 Step S30 includes steps S301 to S303: Step S301: When the droplet passing signal is abnormal, the motor-driven clamping device is triggered to periodically squeeze the outside of the drip bucket to remove mist or attachments in the infusion drip bucket; It should be understood that the clamping device includes a stepper motor, a transmission gear set and a flexible silicone clamp, the clamping pressure range is 0.1-0.5N, and the extrusion frequency is 1-3 times / second. And after the squeezing action, the cleaning effect is judged by the recovery of the infrared receiver signal 912.

[0047] The surface of the flexible silicone chuck is coated with a hydrophobic coating with a contact angle of ≥150°, which is used to reduce droplet adhesion and enhance cleaning efficiency14.

[0048] It should be noted that the presence of characteristics of the droplet passing signal that do not conform to the normal pattern, such as abnormal fluctuations in signal intensity, disordered time intervals, or discontinuity, may be caused by factors such as mist in the drip chamber, droplet splashing, or blockage or distortion of the infusion tube; The system activates the motor-driven clamping device according to the preset control logic. The device is installed on the outside of the drip bucket. The rotation of the motor drives the clamping device to squeeze the drip bucket. The clamping device regularly and periodically squeezes the outside of the drip bucket at a preset frequency and force. This squeezing action simulates manual squeezing of the drip bucket, changing its shape to disperse or discharge the mist inside, while loosening and removing foreign matter adhering to the inner wall of the drip bucket. During the squeezing process, the liquid flow and pressure changes inside the drip bucket help to dissipate the mist and remove the attachments, thereby reducing interference with the droplet passing signal and improving the accuracy of monitoring.

[0049] Step S302: After the squeezing is completed, the infrared signal effect of the infusion dropper is detected by the dual-channel infrared sensor group; It should be noted that the dual-channel infrared sensor group is a sensor array composed of two independent infrared detection units, which use different wavelengths (such as 850nm and 1550nm) or detection modes (transmission / reflection).

[0050] The infrared signal effect can be divided into the transmitted light intensity: the baseline value in the clean state is 100% (no attachments). When there is crystal or fog on the inner wall, the transmittance decreases exponentially (formula: , where α is the material absorption coefficient and d is the thickness of the attachment).

[0051] Scattering pulse stability: During normal infusion, the droplet interval time is normally distributed (standard deviation σ≤0.2s). If there is wall hanging or bubble interference, the σ value will increase.

[0052] Step S303 , evaluating the cleaning effect based on the infrared signal effect, and adjusting the frequency and strength of subsequent squeezing operations according to the cleaning effect.

[0053] It should be understood that the squeezing frequency and the force frequency can be adjusted, for example, from the default 10 minutes / time to 2-30 minutes / time dynamically, by changing the duty cycle of the motor drive PWM signal.

[0054] Furthermore, when the shaking amplitude recovers to below a preset threshold or the squeezing action is effective in cleaning, the current drop count statistics based on the droplet passing signal are restored and the historical stable flow rate value is updated.

[0055] It should be noted that the system can also analyze and determine the effectiveness of the squeezing action in removing mist and debris based on the pressure change data detected by the pressure sensor. For example, if the pressure change trend indicates that the mist has basically dissipated or the debris has loosened and fallen off, the cleaning effect is considered to be good.

[0056] During the squeezing process, the pressure sensor continuously records the changes in pressure values. These changes reflect the impact of the squeezing action on the drip bucket and the removal of mist and attachments inside the drip bucket.

[0057] Based on the evaluation results, the system automatically adjusts the frequency and force of subsequent squeezes in the clamping device. If the cleaning effect is good, the squeeze frequency and force can be appropriately reduced to reduce interference with the infusion process; if the cleaning effect is poor, the squeeze frequency and force can be appropriately increased to enhance the cleaning effect.

[0058] The method also includes: Obtain the remaining infusion volume; Determine the estimated infusion completion time based on the updated historical stable flow rate value and the remaining infusion volume; Send the estimated infusion completion time to the cloud server for display on the monitoring interface of the hospital information system; When the deviation between the estimated infusion completion time and the actual infusion progress exceeds the preset time range, the early warning mechanism is automatically triggered to ensure normal infusion.

[0059] It should be noted that when the shaking amplitude returns to below the preset threshold or the squeezing action is effective, the system considers that the droplet passing signal has returned to normal, restarts the current drop count based on the droplet passing signal, and updates the historical stable flow rate value based on the new drop count data, providing a more accurate reference for subsequent infusion monitoring; Obtain the remaining amount of infusion in the current infusion bag or infusion bottle through sensors or other measuring means on the infusion device; Calculate the estimated infusion completion time based on the updated historical stable flow rate value and the remaining infusion volume. Expected infusion completion time = Remaining infusion volume / (Historical stable flow rate value × Conversion factor between drop count and flow rate); Sending the estimated infusion completion time to the cloud server: The calculated estimated infusion completion time is sent to the cloud server via the wireless transmission module so as to be displayed on the monitoring interface of the hospital information system; When the deviation between the estimated infusion completion time and the actual infusion progress exceeds the preset time range, the system automatically triggers the early warning mechanism to remind medical staff to pay attention to the infusion status in time and take corresponding measures to ensure the normal progress of the infusion.

[0060] This embodiment provides an intelligent infusion drop count monitoring method. By real-time detection of droplet passing signals and motion status data and taking corresponding control measures in abnormal situations, it can effectively reduce monitoring errors caused by factors such as equipment shaking and drip bucket fogging, and improve the accuracy and reliability of infusion drop count monitoring.

[0061] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the intelligent infusion drop count monitoring method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
