[0014] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. Many details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0015] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0016] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those generally understood by those skilled in the art of the technical field of this application. The terms used in the description of the embodiments of this application are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of this application. The term "and / or" used in this application includes any and all combinations of one or more related listed items.

[0017] The present application embodiment provides an iodine contrast agent suspension metering device, such as Figure 1 As shown, the metering device includes:

[0018] A hanging component 1 is used for hanging iodine contrast agent; a residual measuring component 2 is connected to the hanging component 1 and is used for measuring the residual amount of the iodine contrast agent to obtain a residual measuring result; a display component 3 is connected to the residual measuring component 2 and is used for receiving and displaying the residual measuring result.

[0019] Specifically, the hanging component 1 is used as the basic supporting structure of the iodine contrast agent hanging metering device, usually in the form of a hook, and the material is made of durable and corrosion-resistant stainless steel. The curvature of its shape design is moderate to the size of the opening, and the opening is slightly larger than the diameter of the bottleneck of a conventional infusion bottle and has a design to increase friction inside, such as fine texture or rubber pad, to ensure that medical staff can easily and quickly hang the container containing iodine contrast agent and it will not slip easily when hanging. In actual medical scenarios such as cardiac interventional surgery, before the operation, medical staff pick up the iodine contrast agent container and place its hanging part accurately on the hook. The height and position of the hook are often adjustable. For example, if it is installed on a liftable infusion stand, medical staff can adjust it to the appropriate height according to the height of the operating table and their own operating habits to ensure smooth infusion of iodine contrast agent and facilitate subsequent residual observation and metering operations. After the container is successfully hung, the device enters a ready state that can monitor and manage the status of the iodine contrast agent at any time.

[0020] As a key part of the iodine contrast agent suspension metering device, the residual metering component 2 is closely connected to the suspension component 1, and is mainly composed of a weight sensor and a metering and analysis unit. It uses a specific stable and precise connection method, such as installing it at the key stress-bearing part of the suspension component 1 or using high-precision connectors, so that the weight sensor can accurately sense the weight change of the iodine contrast agent container and its contents. The sensor converts gravity changes into electrical signals based on advanced sensing technology, and has extremely high sensitivity and accuracy. After the iodine contrast agent container is suspended, the sensor monitors the weight change in real time and transmits electrical signals to the metering and analysis unit. This unit calculates the accurate residual metering result based on comprehensive consideration of the initial weight of the container, the density of the iodine contrast agent and the real-time weight data. This result is of great significance to the management of the use of iodine contrast agents and the safety of surgery. It can help medical staff to reasonably arrange the surgical process and avoid accidents, and ensure the contrast effect and reduce adverse effects in the precise control of dosage scenarios. It is an indispensable and important part of the entire solution.

[0021] The display component 3 establishes a stable and reliable connection with the residual measurement component 2 through wired (such as a data transmission line) or wireless (such as Bluetooth, Wi-Fi, etc.) means to ensure that the residual measurement results can be received in real time. After receiving the results, it presents information with the help of indicator lights and digital display screens according to the preset display logic. The indicator light intuitively reflects the residual status with color, showing green when sufficient, yellow when medium level, and red when low, reminding medical staff of the corresponding situation. The digital display screen accurately displays specific values, such as the number of milliliters or percentages remaining. The display component 3 converts abstract data into intuitive information, which is convenient for medical staff to observe and judge, improve surgical efficiency, reduce the risk of surgical interruption, and help them accurately control the dosage. It is of great significance to ensure patient medical safety and improve medical quality, and is a key link in the efficient and safe use and management of iodine contrast agents.

[0022] In a possible implementation, the remaining amount measuring component 2 includes a weight sensor and a measuring and analyzing unit. The weight sensor is connected to the suspension component 1, and is used to sense and monitor the weight information of the iodine contrast agent and send it to the measuring and analyzing unit. The measuring and analyzing unit is used to measure the remaining amount of the iodine contrast agent according to the weight information to obtain the remaining amount measuring result.

[0023] Specifically, the weight sensor serves as the front-end sensing unit of the residual metering component 2 and is closely connected to the suspension component 1. Its main task is to accurately sense and monitor the weight information of the iodine contrast agent. When the container containing the iodine contrast agent is suspended by the suspension component 1, the weight sensor is based on the sensing principle, such as strain gauge sensing technology. When it is subjected to the pressure generated by the weight of the iodine contrast agent container and the liquid therein, the strain gauge will deform, thereby causing its resistance value to change. The change in resistance value is in a certain proportional relationship with the weight it bears. The change in resistance value is converted into an electrical signal through a built-in high-precision measurement circuit. The electrical signal undergoes signal conditioning, such as amplification, filtering and other processing processes to enhance the stability and accuracy of the signal, and then the processed weight information is sent to the metering and analysis unit in real time. During the entire operation, the weight sensor continuously monitors the weight change. Even extremely small weight changes can be captured in time and converted into corresponding electrical signal transmission, providing the most basic data support for subsequent residual measurement.After receiving the weight information from the weight sensor, the metering and analysis unit performs calculations to obtain the remaining measurement result of the iodine contrast agent. First, the metering and analysis unit will call up the relevant parameters stored in advance, including the initial weight data of the iodine contrast agent container, which has been accurately obtained and stored in the unit during the installation or calibration stage of the device, as well as the density information of the iodine contrast agent used, which is set according to the specific type and model of the iodine contrast agent. According to the relationship formula between weight difference and density, the real-time weight transmitted by the current weight sensor is subtracted from the initial weight to obtain the weight of the used iodine contrast agent, and then the used volume is calculated according to the density, and then the volume or mass of the remaining iodine contrast agent is calculated, and finally an accurate remaining measurement result is obtained. During the calculation process, the metering and analysis unit will also take into account some factors that may affect the measurement accuracy, such as the impact of temperature changes on the accuracy of the weight sensor (if any), and correct it through the built-in temperature compensation algorithm to ensure the high accuracy and reliability of the remaining measurement result. The metering and analysis unit will continuously update the calculation results. As the weight sensor continuously transmits new weight information, it will reflect the dynamic changes of the iodine contrast agent residue in real time, providing the most timely and accurate residue data for medical staff. The residue metering component 2 realizes the accurate measurement of the iodine contrast agent residue through the coordinated work of the weight sensor and the metering and analysis unit. The measurement results provide key information for medical staff during the operation. Medical staff can reasonably arrange the use rhythm of iodine contrast agents according to the residue situation, avoid accidental interruption of the operation due to insufficient residue, and ensure the continuity and safety of the operation. Accurate residue measurement helps to control the total usage of iodine contrast agents, which is of great significance for medical scenarios that require strict control of medication dosage, such as protecting patients' renal function during cardiac interventional surgery. The data provided by the residue metering component 2 is also the basis for the subsequent display component 3 to perform intuitive display, and is an important basis for realizing the functional integrity and effectiveness of the entire device, and provides indispensable technical support for the efficient and safe use and management of the entire iodine contrast agent.

[0024] In a possible implementation, the hanging component 1 is a hook.

[0025] Specifically, the hanging component 1 is a hook, and its material is usually medical grade stainless steel, which is durable and corrosion-resistant, and can bear the weight of iodine contrast agent containers of different specifications, ensuring long-term stability and reliability. The shape of the hook is cleverly designed, the curvature matches the hanging part of the container, the opening size is moderate and the edges are rounded, which is convenient for the container to be hung and prevented from slipping. In actual medical scenarios such as the preparation stage of cardiac interventional surgery, medical staff hold the iodine contrast agent container, align its hanging part with the hook opening and easily hang it in. The hook is installed on an infusion stand or support device with adjustable height and position. Medical staff can adjust it according to the height of the operating table, the patient's position and their own operating convenience to ensure smooth infusion and facilitate observation and operation of related equipment. As a basic supporting structure, the hook provides a stable hanging point for the entire iodine contrast agent suspension metering device, ensures that subsequent operations are carried out in an orderly manner, avoids accidents, and improves the work efficiency of medical staff, which is of great significance to the safe and efficient management and use of iodine contrast agents.

[0026] In a possible implementation, the dosage metering component 4 is connected to the infusion pump of the iodine contrast agent and is used to measure the dosage of the iodine contrast agent.

[0027] Specifically, the dosage metering component 4 is connected to the infusion set of the iodine contrast agent through a clip-type or nested connection design. The clip-type connection can be conveniently clamped at a suitable position of the infusion tube, and the nested connection tightly nests the interface of the dosage metering component with a specific part of the infusion set. The dosage metering component 4 contains a high-precision flow sensor and a matching data processing unit. The flow sensor is its core component. Based on the principle of electromagnetic induction, it accurately senses the flow change of the iodine contrast agent when it flows in the infusion tube. When the iodine contrast agent flows through the infusion set under the action of gravity or an infusion pump, the flow sensor will capture the flow rate and flow information of the liquid in real time. During the operation, as the iodine contrast agent begins to pass through the infusion set, the flow sensor will capture the flow rate and flow information of the liquid in real time. After infusion to the patient, the dosage metering component 4 starts working, the flow sensor continuously monitors the flow of the iodine contrast agent in the infusion tube, converts the flow rate information into an electrical signal, and transmits it to the data processing unit. After receiving the signal, the data processing unit performs calculations, stores and records, and records the time point when the iodine contrast agent starts to be infused. Then, based on the real-time flow rate data transmitted by the flow sensor, the total volume of the iodine contrast agent passing through the infusion device within a certain period of time is calculated by integral operation, thereby achieving accurate measurement of the amount of iodine contrast agent used. For example, if the flow sensor detects that the flow rate at a certain moment is 5 ml / min, after 10 minutes of infusion, the data processing unit can calculate that the amount used during this period is 50 ml. During the entire infusion process, the dosage metering component 4 continuously updates the calculation results to provide real-time and accurate iodine contrast agent dosage information. The iodine contrast agent dosage data accurately measured by the dosage metering component 4 provides key information for medical staff, which helps medical staff to better control the dosage of iodine contrast agents used, ensuring that while achieving the contrast effect, the adverse effects of iodine contrast agents on patients are minimized. Accurate dosage control is particularly important, especially for patients with heart failure or potential risks to renal function. The dosage data can also be used for postoperative medical records and analysis, providing valuable data support for evaluating the rationality of the use of iodine contrast agents during surgery, optimizing subsequent treatment plans, and conducting clinical research, further improving the quality and safety of medical services, and is an important guarantee for the scientific, reasonable and safe use of iodine contrast agents.

[0028] In a possible implementation, the display component 3 includes an indicator light, and the indicator light displays different contents according to different ranges of remaining quantity measurement results, wherein the different contents include different colors.

[0029] Specifically, the indicator light in the display component 3 is closely related to the residual measurement result. When the residual measurement component 2 obtains the measurement result and transmits it to the display component 3, its control circuit controls the indicator light according to the preset corresponding relationship. If the residual is greater than 2 / 3 of the total amount of the container, the indicator light will display green, informing the medical staff that normal operation is possible; if the residual is between 1 / 3-2 / 3, it will display yellow, reminding the medical staff to prepare for replenishment; if the residual is less than 1 / 3, it will display red, warning the medical staff to act immediately. This different color display method is of great assistance in surgery, allowing medical staff to quickly obtain key information, improve work efficiency, reduce the risk of surgical interruption, optimize the use and management of iodine contrast agents, and ensure surgical quality and patient safety. It is an important part of the solution.

[0030] In the above, refer to Figure 1 A iodine contrast agent suspension metering device according to an embodiment of the present invention is described in detail. Figure 2 A method for suspending and metering an iodine contrast agent according to an embodiment of the present invention is described.

[0031] A method for measuring the iodine contrast agent suspension, such as Figure 2 As shown, the method includes:

[0032] Step S100, in the process of iodine contrast agent suspension, through the weight sensor in the surplus metering component, the weight information of the iodine contrast agent is obtained by sensing and detecting. Specifically, in the process of iodine contrast agent suspension, the weight sensor in the surplus metering component plays a key role. It is installed at a place closely connected with the suspension component, and during installation, it is ensured to be firmly connected and can accurately sense weight changes. After installation, self-calibration is first performed to eliminate errors. When the iodine contrast agent container is suspended thereon, based on the sensing principle such as strain gauge or piezoelectric type, the elastic element deformation of the strain gauge sensor under the weight of the container changes the resistance value of the strain gauge, and is converted into a voltage signal through a measuring circuit. The piezoelectric sensor utilizes the piezoelectric effect of piezoelectric material to generate an electric charge and then converts it into a voltage signal. After the voltage signal is processed by amplification, filtering, etc., through a reliable data transmission method, such as a high-precision analog signal transmission line or a digital communication protocol (if any), the weight information that changes with the use of the iodine contrast agent monitored in real time is accurately transmitted to the measurement and analysis unit, providing a reliable data source for subsequent operations, and ensuring the reasonable use and timely replenishment of the iodine contrast agent.

[0033] Step S200, according to the weight information, the residual measurement result of the iodine contrast agent is obtained by classification. Specifically, after obtaining the weight information, it is first pre-processed, such as noise reduction and verification data, and then the parameters such as the initial weight of the iodine contrast agent container and the density of the iodine contrast agent stored in advance are called. According to the physical formula and algorithm, the weight of the used iodine contrast agent is calculated by the difference between the current weight and the initial weight, and the used volume is obtained in combination with the density, and then the remaining volume is calculated. According to the set classification standard, such as being divided into categories such as "sufficient", "medium" and "insufficient" according to the ratio of the residual volume to the initial volume of the container, the category to which the residual measurement result belongs is determined, and the result verification is performed at the same time, including data rationality check and comparison with historical or empirical data, and an alarm is issued if there is a deviation. During the operation, as the weight information is updated, the calculation and classification process is continuously repeated to dynamically update the residual measurement result, helping medical staff to reasonably arrange the operation, control the dosage and ensure the safe and efficient operation.

[0034] In a possible implementation, the residual measurement result of the iodine contrast agent is obtained by classification according to the weight information, and step S200 further includes step S210, collecting a sample weight information set and a sample residual measurement result set according to the residual weight test data of the iodine contrast agent. Specifically, to construct an accurate residual measurement model, a large amount of iodine contrast agent residual weight test data is first required. In actual operation, various different usage scenarios will be simulated, such as different infusion speeds, different container starting capacities, different ambient temperatures, etc., to accurately measure the residual weight of the iodine contrast agent during use. For example, in a set of tests, a 100ml iodine contrast agent container is used, and an infusion is performed at a speed of 5ml / min. The total weight of the iodine contrast agent container and the remaining liquid at this time is recorded once every certain time (such as 1 minute), thereby obtaining a series of data points about the change of the residual weight of the iodine contrast agent over time. These data points constitute the sample weight information set. For each sample weight information, it is necessary to determine the corresponding accurate residual measurement result through precise measurement methods or known physical relationships, thereby forming a sample residual measurement result set. For example, the initial total weight of the container (including the container and the full bottle of iodine contrast agent) and the density of the iodine contrast agent are known. The volume of the used iodine contrast agent is calculated by the weight difference, and then the volume or mass of the remaining iodine contrast agent is obtained as the residual measurement result. Taking a certain measurement as an example, the initial total weight is 500 grams. When the weight at a certain moment is 350 grams, the volume of the used iodine contrast agent is calculated according to the density, thereby determining the residual measurement result of the remaining iodine contrast agent at this time, such as 60 ml remaining, and associating it with the corresponding weight information of 350 grams and including it in the sample set.

[0035] Step S220, using the sample weight information set and the sample remainder measurement result set to construct a remainder measurement classifier. Specifically, according to the collected sample weight information set and the sample remainder measurement result set, a suitable machine learning classification algorithm is selected to construct the remainder measurement classifier, such as a classification algorithm decision tree algorithm. By selecting the decision tree algorithm, the data can be gradually divided according to the different characteristics of the sample weight information (such as different weight intervals) to construct a decision tree model. Each node represents a feature judgment, each branch represents a judgment result, and the final leaf node corresponds to a different category of residual measurement results. The sample weight information set is used as the input feature and the sample residual measurement result set is used as the output label to train the selected classification algorithm. During the training process, the classification algorithm will learn the intrinsic relationship and pattern between the weight information and the residual measurement results according to the sample data. For example, the decision tree algorithm will select the optimal feature (weight interval) for node splitting by calculating indicators such as information gain under different weight intervals, and gradually construct a decision tree structure, so that the model can accurately predict the corresponding residual measurement results for new weight information input. By continuously adjusting the parameters of the model (such as the depth of the decision tree, the threshold for node splitting, etc.), the performance of the model is optimized until the model achieves a high accuracy and stability on the training samples.

[0036] Step S230, input the weight information into the residual measurement classifier, and classify to obtain the residual measurement result. Specifically, when new iodine contrast agent weight information is obtained, it is input into the residual measurement classifier that has been constructed. The classifier will process and judge the input weight information according to the previously learned patterns and relationships. For example, if a decision tree classifier is used, the weight information will start from the root node, and according to the branching rules of the decision tree, it will pass through the judgment of each node in turn, and finally reach a leaf node. The category corresponding to the leaf node is the residual measurement result output by the classifier. Assuming that the input weight information is 300 grams, the decision tree classifier will finally determine the residual measurement result according to the pre-constructed model after a series of judgments (such as whether the weight is greater than 320 grams, whether it is greater than 280 grams, etc.). The residual measurement result category corresponding to the weight is determined, such as "small residual" or a specific residual range. The residual measurement result output by the classifier can be directly provided to medical staff or other related systems for use. Medical staff can understand the residual situation of iodine contrast agent in time according to the result, so as to reasonably arrange the operation process, such as deciding whether to prepare new iodine contrast agent container, adjusting the infusion speed and other operations, so as to ensure the smooth progress of the operation and the safety of the patient. The result can also be used as the basis for subsequent data analysis and statistics, such as recording the use of iodine contrast agents in different operations, providing data support for optimizing the allocation of medical resources, improving the surgical process, etc., and further improving the quality and efficiency of medical services.

[0037] Step S300, according to the residual measurement result, the residual display information is generated and displayed through the display component. Specifically, when the residual information is generated and displayed according to the residual measurement result, the system first interprets the analysis results, such as "sufficient" (greater than 2 / 3 of the total amount of the container), "medium" (between 1 / 3-2 / 3 of the total amount of the container), "insufficient" (less than 1 / 3 of the total amount of the container) and other categories. After determining the category, the corresponding template or instruction is selected from the preset display information library, such as "sufficient" when the green indicator light is on and the specific residual value and the "sufficient" word template are displayed on the digital display screen. The generated information is transmitted to the display component, and the control circuit drives the corresponding display element after receiving it. If the green light needs to be on, a signal is sent to the indicator circuit to make it light up. The digital display part sends the residual value and word signal to the display driver chip to convert it into a pixel signal, accurately displaying the residual situation, helping medical staff to arrange surgical operations, and ensuring the smooth progress of the operation and the safety of patients.

[0038] In a possible implementation, according to the residual measurement result, residual display information is generated and displayed through a display component. Step S300 further includes step S310, obtaining multiple sample residual intervals, and configuring different residual display information for different sample residual intervals to obtain multiple sample residual display information. Specifically, obtaining multiple sample residual intervals is achieved by measuring the weight of iodine contrast agent containers at different use stages in actual or simulated surgical scenes. For example, in an experimental environment, multiple containers containing different initial amounts of iodine contrast agents (such as 50ml, 80ml, 100ml, etc.) are prepared to simulate the infusion process during surgery. The weight of the container and the remaining liquid is measured once every certain time (such as 5 minutes), and the residual is calculated according to the weight change. Through multiple measurements and calculations, different sample residual intervals such as "0-30ml", "31-60ml", and "61-90ml" are determined. The division of the intervals should take into account the common use of iodine contrast agents in surgery and the residual variation range, so as to accurately remind medical staff of the residual amount of iodine contrast agents. For each determined sample residual status, the corresponding residual display information is configured. For the residual range of "0-30ml", due to the small residual amount, a red flashing indicator light and the prompt message "The residual amount is extremely low, please replace it in time" may be configured on the digital display screen; for the range of "31-60ml", a yellow indicator light that is always on and the display message "The residual amount is medium, please pay attention to observe" are configured; for the range of "61-90ml", a green indicator light that is always on and the display message "Sufficient residual amount" are configured. The configuration of the display information is intended to convey the residual status of the iodine contrast agent to medical staff in an intuitive and clear manner, so that they can quickly obtain key information during the operation and make corresponding decisions, such as whether to prepare to replenish the iodine contrast agent.

[0039] Step S320, construct a mapping relationship between the multiple sample remaining intervals and the multiple sample remaining display information. Specifically, after the sample remaining interval is determined and the corresponding sample remaining display information is configured, a mapping relationship between the two is constructed, which is implemented by programming or using a configuration file. For example, a data structure is created in the system software to associate and store each sample remaining interval with the corresponding display information. Data structures such as hash tables or arrays can be used to achieve efficient search and mapping. When the system receives the remaining measurement result, it can quickly find the corresponding display information through this mapping relationship. The mapping relationship ensures that the appropriate display information can be accurately output according to the actual remaining situation. It is a key link in realizing the visual remaining display function. The constructed mapping relationship is stored in the storage medium of the device, such as an internal memory or an external memory card. During the storage process, the integrity and accuracy of the mapping relationship must be ensured to prevent data loss or errors. At the same time, in order to facilitate subsequent maintenance and updates, the storage format of the mapping relationship should have certain readability and scalability. For example, a structured data format (such as JSON or XML) can be used to store the mapping relationship, so that when new sample margin intervals and display information need to be modified or added, they can be easily edited and updated without affecting the stability and functionality of the entire system.

[0040] Step S330, mapping to obtain corresponding remaining quantity display information according to the sample remaining quantity interval into which the remaining quantity measurement result falls, and displaying it through a display component. Specifically, after obtaining the real-time residual measurement result, the system first determines which sample residual interval the result falls into. For example, after measurement and calculation by the weight sensor, the current residual amount of iodine contrast agent is 45ml. By comparing with the previously constructed sample residual interval, it is determined that it falls into the "31-60ml" interval. According to the determined sample residual interval, the established mapping relationship is used to quickly obtain the corresponding residual display information. In the above example, the system will read the yellow always-on indicator light and the display information of "medium residual amount, please pay attention to observe" corresponding to the "31-60ml" interval from the storage medium, and transmit the information to the display component for display. After receiving the information, the control circuit in the display component drives the indicator light to light yellow and displays the corresponding text prompt on the digital display screen. Medical staff can see the residual status of the iodine contrast agent at a glance during the operation and make reasonable operational decisions in time, such as adjusting the infusion speed according to the residual situation or preparing to replenish the iodine contrast agent in advance, so as to ensure the smooth progress of the operation and the safety of the patient.

[0041] In a possible implementation, multiple sample residual intervals are obtained, and different residual display information is configured for different sample residual intervals, and multiple sample residual display information is obtained. Step S310 further includes step S311, and the multiple sample residual display information includes multiple display colors. Specifically, when constructing the sample residual display information, the display color is crucial. First, the intervals are divided according to the residual situation in the actual use of the iodine contrast agent, such as "low residual interval" (residue is less than 1 / 3 of the total amount of the container), "medium residual interval" (residue is between 1 / 3-2 / 3 of the total amount of the container), "high residual interval" (residue is greater than 2 / 3 of the total amount of the container), etc., and then different display colors are configured respectively. The "low residual interval" is set to red, because it is eye-catching, it can prompt medical staff to notice that the residual is low and needs to be handled as soon as possible; the "medium residual interval" is set to yellow, which serves as a warning and reminds to pay attention to the residual change; the "high residual interval" is set to green, which represents sufficient safety, allowing medical staff to operate with peace of mind. In actual surgery, after the remaining amount is measured, the system determines the interval based on the remaining amount and maps the corresponding color display. For example, red prompts medical staff to suspend non-critical operations to check the supply, yellow reminds them to pay attention to changes, and green allows medical staff to focus on the operation, which helps to improve the safety and smoothness of the operation.
