These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0045] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the invention described herein, for example, can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0047] Flushing the tube is a routine operation during enteral nutrition infusion. Its purpose is to prevent tube blockage and replenish water. Strengthening the flushing of the tube can effectively prevent nasogastric tube blockage, but excessive flushing in a short period of time can also lead to diarrhea complications. Therefore, it is necessary to accurately control the flushing parameters to ensure the treatment effect.

[0048] However, the flushing parameters of current nutritional infusion equipment can only be set manually by medical staff, which has low parameter setting efficiency and cannot adjust the flushing scheme according to the working status of the nutritional infusion equipment during the actual feeding process. Tube blockage or excessive flushing may still occur, affecting the treatment effect.

[0049] In order to solve the above problems, the present application provides a control method for a nutrition infusion device. The present application takes into account that the flushing of the nutrition infusion device is closely related to the feeding process, so the feeding parameters are associated with the flushing parameters. After the user sets the feeding parameters, the flushing parameters are directly and automatically determined according to the pre-set flushing rules, without the need to manually set the flushing parameters, thereby improving the parameter setting efficiency. In addition, the present application also obtains the working status information of the nutrition infusion device during the actual feeding process, so as to adjust the flushing parameters according to the actual feeding situation, thereby reducing the risk of tube blockage and avoiding excessive flushing in a short period of time, thereby improving the treatment effect.

[0050] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0051] First, the structure of the nutrition infusion device involved in this application is briefly introduced.

[0052] For example, Figure 1A This is a schematic diagram of the structure of a nutrition infusion device provided in an embodiment of the present application. Figure 1B A schematic diagram of the structure of an infusion circuit provided in an embodiment of the present application. Figure 1B The structural diagram of the infusion circuit shown is Figure 1A Detailed view of the infusion line section in the nutrition infusion device shown. Figure 1A and Figure 1B As shown, the nutrition infusion device 100 of the present application at least includes a controller (not shown in the figure), a driving member (not shown in the figure), a driving actuator 15 and a delivery tube 10. The controller is electrically connected to the driving member, and the driving member is transmission-connected to the driving actuator, and the driving actuator is arranged on the pipeline path of the delivery tube 10. Under the control of the controller, the driving member drives the driving actuator 15 to rotate, thereby driving the fluid flow in the delivery tube 10. Among them, the delivery tube 10 includes a nutrient solution pipeline 11, a flushing liquid pipeline 12 and a silicone tube 16. When performing infusion control, the on-off status of the nutrient solution pipeline 11 and the flushing liquid pipeline 12 is controlled by controlling the three-way valve (not shown in the figure) to control the nutrition infusion device 100 to infuse nutrient solution or flushing liquid.

[0053] In addition, if Figure 1A As shown, the nutrition infusion device 100 may also include a display screen 13, a button 14, a pump door 17, a consumables support plate 18 and other components. Figure 1BThe three-way valve can be fixed by the three-way valve buckle groove 19, the consumable support plate 18 can be fixed by the consumable support plate buckle 20, and the pipeline can be fixed by the pipe joint buckle groove 21. Among them, the display screen 13 of the nutrition infusion device 100 is used to display parameter information related to nutrition infusion, and medical staff can set feeding parameters, flushing parameters and other information displayed on the display screen.

[0054] Next, the process of how to control the feeding and flushing of the nutrition infusion equipment is introduced in detail.

[0055] Figure 2 A flowchart of a control method for a nutrition infusion device provided in an embodiment of the present application. The execution subject of the embodiment of the present application may be a control device of the nutrition infusion device, and the control device may be located on the nutrition infusion device, or on a medical device such as an infusion central station, an infusion workstation, or an infusion monitoring system connected to the nutrition infusion device, and the present application does not make any limitation. The embodiment of the present application is described in detail by taking the execution subject as the control device as an example.

[0056] like Figure 2 As shown, the control method of the nutrition infusion device provided in this embodiment includes:

[0057] S201, obtaining feeding parameters.

[0058] For example, based on Figure 1A The nutritional infusion device shown, when the nutritional infusion device is turned on, can display a feeding parameter setting interface on the display screen, and the user can set the feeding parameters based on the setting interface, so that the control device of the nutritional infusion device of the present application can obtain the feeding parameters. In addition, the control device of the nutritional infusion device of the present application can also obtain feeding parameters from other devices such as a medical system, a cloud, an infusion central station, an infusion workstation, an infusion monitoring system, etc., and this application does not limit it.

[0059] The feeding parameters characterize all parameters related to the nutrient solution feeding process. For example, the feeding parameters may include one or more of the following: nutrient solution type, nutrient solution concentration, nutrient solution feeding amount, feeding mode, feeding speed, feeding time, and patient type.

[0060] For example, medical staff can set the type of nutrient solution, nutrient solution concentration, nutrient solution feeding amount, feeding mode, feeding speed, feeding time, and patient type to be infused by the feeding subject in the feeding parameter setting interface according to the actual nutrient infusion needs of the feeding subject. The feeding mode can be continuous or intermittent feeding, etc., which is not limited in this application.

[0061] Exemplarily, continuous feeding generally refers to a continuous feeding method that provides more than 24 hours of continuous feeding. Continuous feeding is better tolerated for patients with poor intestinal absorption capacity or gastrointestinal dysfunction, and is also a feeding method that is widely used in critically ill patients in clinical practice. Intermittent feeding generally refers to a feeding method that provides 4 to 6 feedings a day, each feeding for 20 to 60 minutes. It is a feeding method that is more in line with physiological characteristics, which is convenient for the feeding subject to get out of bed or undergo treatment, examination and other activities. When setting parameters, medical staff can choose a suitable feeding mode according to the physical condition of the feeding subject and the treatment plan to be carried out. For example, if the feeding subject is a critically ill patient with poor intestinal absorption capacity, continuous feeding can be selected to provide sufficient nutrition for the feeding subject; if the feeding subject needs auxiliary training or needs to be examined during a specific time period, intermittent feeding can be selected to facilitate the arrangement of the feeding subject's time.

[0062] In a possible example, the feeding parameters can also be indirectly determined by analyzing the nutritional infusion requirement information and / or the feeding object information and / or the vital sign status parameters of the feeding object. Among them, the nutritional infusion requirement information can include one or more of the nutrient solution type, feeding mode, feeding speed, feeding amount, feeding time, etc., the feeding object information can include one or more of the patient's weight, weight change, age, calorie consumption, height, gender, patient type, and the patient's disease information, etc., and the vital sign status parameters can include one or more of the end-tidal carbon dioxide index EtCO2, hemodynamic index, blood sugar index, heart rate, blood pressure, electrocardiogram, body temperature, blood oxygen saturation, pulse, etc. For example, what the medical staff inputs in the feeding parameter setting interface is not the feeding parameter itself, but the nutritional infusion requirement information and / or feeding object information and / or vital sign status parameters of the feeding object. Of course, these parameters can also be retrieved from a monitor, or a hospital information system (HIS) or a clinical information system (CIS), or a nutrition system software, and this application does not limit it. After obtaining these parameters, the nutrition infusion device can automatically analyze the information to determine the feeding parameters of the present application.

[0063] Among them, the present application does not limit how the nutritional infusion device determines the feeding parameters according to the nutritional infusion demand information and / or the feeding object information and / or the vital signs status parameters of the feeding object. For example, the nutritional infusion demand information and / or the feeding object information and / or the vital signs status parameters of the feeding object can be input into a preset data analysis model, a neural network algorithm model, a clustering algorithm model, etc., and the parameters output by the model are determined to be the feeding parameters; the historical feeding parameters of the feeding object can also be retrieved, and then the nutritional infusion demand information and / or the feeding object information and / or the vital signs status parameters of the feeding object are compared and matched with the historical feeding parameters, and the historical feeding parameters with the highest matching degree are determined as the feeding parameters for this time. And so on, the nutritional infusion demand information and / or the feeding object information and / or the vital signs status parameters of the feeding object can be analyzed in a variety of ways, and it is only necessary to determine the feeding parameters.

[0064] S202: Determine a first flushing parameter according to the feeding parameter and a preset flushing rule.

[0065] For example, after obtaining the feeding parameters, the control device of the nutrition infusion device of the present application can automatically generate a set of suitable flushing schemes based on the feeding parameters and the preset flushing rules. The flushing scheme has corresponding flushing parameters, which are determined as the first flushing parameters, and the first flushing parameters are the default flushing values. Accordingly, medical staff only need to set the feeding parameters, and no longer need to set the flushing parameters, which improves the efficiency of parameter setting.

[0066] Exemplarily, the flushing parameters characterize all parameters related to the flushing process. For example, the flushing parameters may include one or more of the following: flushing mode, flushing speed, flushing total amount, flushing interval, single flushing amount, and flushing times. Among them, the flushing mode may be pulse flushing or uniform flushing. When flushing at a uniform speed, different flushing speeds may also be set, which is not limited in this application.

[0067] Exemplarily, pulse flushing is a flushing method that uses a push-and-stop method, which can cause the flushing liquid to generate positive and negative pressures in the catheter cavity to form vortices, increase the comprehensive and uniform flushing of the catheter wall, and effectively flush the residual drugs attached to the catheter wall, more effectively reducing the occurrence of blockage. Uniform flushing is a flushing method that controls the continuous and uniform flow of the flushing liquid. When the flushing liquid flows in the pipeline, the greater the flow velocity in the center of the lumen, the smaller the flow velocity is closer to the tube wall, and the flow velocity at the contact point with the tube wall is close to zero, forming a direct current water flow, and the flushing effect is limited. When determining the flushing method, if the type of nutrient solution is relatively viscous, and / or the concentration of the nutrient solution is relatively high, in order to achieve a better flushing effect and effectively avoid clogging, the flushing method can be determined to be pulse flushing; and if it is determined that the feeding object does not have high requirements for the flushing effect and needs to be replenished with water, the flushing method can be determined to be uniform flushing.

[0068] In one embodiment, the preset flushing rule can be determined according to the corresponding relationship between the feeding parameter and the flushing parameter. Different feeding parameters should use different flushing parameters. The present application does not limit the specific flushing rule. For example, when determining the flushing parameter, the flushing method and flushing speed can be determined according to the nutrient solution type and / or nutrient solution concentration. According to the flushing total amount and feeding mode, the flushing interval, single flushing amount, etc. can be determined. The flushing parameters corresponding to the feeding parameters of different feeding objects may be different, which should be considered comprehensively in combination with the overall situation of the feeding object. For example, when the nutrient solution type in the feeding parameter is relatively viscous, and / or the nutrient solution concentration is relatively high, then the corresponding larger flushing speed, larger flushing total amount, shorter flushing interval, and more flushing times, etc. are determined according to the preset flushing rule; on the contrary, when the nutrient solution type in the feeding parameter is relatively thin, and / or the nutrient solution concentration is relatively low, then the corresponding smaller flushing speed, smaller flushing total amount, longer flushing interval, and fewer flushing times, etc. are determined according to the preset flushing rule. Of course, the preset flushing rules can also determine the corresponding flushing parameters based on one or more other feeding parameters (such as nutrient solution feeding amount, feeding mode, feeding speed, feeding time, patient type), which are not limited here one by one.

[0069] For example, a mapping table characterizing the correspondence between each feeding parameter and each flushing parameter is pre-set, and the mapping table includes, for example, the correspondence between the nutrient solution type and the flushing method, the correspondence between the nutrient solution concentration and the flushing speed, the correspondence between the feeding mode and the flushing interval, etc. After the nutrient solution type is determined, the flushing method can be determined based on the correspondence between the nutrient solution type and the flushing method in the mapping table; after the nutrient solution concentration is determined, the flushing speed can also be determined based on the correspondence between the nutrient solution concentration and the flushing speed in the mapping table, and so on. Each parameter in the flushing parameter can be determined based on the information in the mapping table.

[0070] In addition, in another embodiment, the preset flushing rule can also be set as a functional relationship between one or more feeding parameters and each flushing parameter according to the relationship between the two, wherein the input parameter is one or more feeding parameters, and the output function value is a flushing parameter. The preset flushing rule includes multiple functional relationships as described above, and the output function value of each functional relationship corresponds to a different flushing parameter. When one or more feeding parameters are obtained, they are substituted into multiple functional relationships as described above to calculate the corresponding flushing parameters. Based on the flushing parameters and the functional relationship, the corresponding feeding parameters can also be calculated in reverse, and the specific implementation of this application is not limited. For example, according to the amount of nutrient solution fed and the feeding speed, the feeding time can be calculated. When the feeding time exceeds the preset threshold, it is necessary to flush once every n hours of continuous feeding. Based on this, according to the feeding time and the time n, the number of flushing times can be calculated; for example, if the flushing speed is set to be m times the feeding speed, the flushing speed can also be calculated after determining the feeding speed; and so on, for the feeding parameters and flushing parameters with a functional relationship, the corresponding parameter values ​​can be determined in this way.

[0071] Furthermore, in another embodiment, the preset flushing rule can also be a combination of the above-mentioned mapping table and the above-mentioned functional relationship. For example, after the user sets the type of nutrient solution to be infused by the feeding object on the parameter setting interface, the flushing method can be determined based on the corresponding relationship between the nutrient solution type and the flushing method in the mapping table. After setting the nutrient solution concentration, the flushing speed can be determined based on the corresponding relationship between the nutrient solution concentration and the flushing speed in the mapping table, and so on. By analogy, some flushing parameters determined by the corresponding relationship are determined. For other flushing parameters, such as the number of flushing times, after setting the nutrient solution feeding amount and feeding speed, the feeding time can be calculated according to the formula, and then the number of flushing times can be calculated according to the feeding time and the preset functional relationship; and so on. The flushing parameters calculated by the formula are also determined. Accordingly, the flushing parameters that match the feeding parameters are determined through the corresponding relationship and the functional relationship between the parameters.

[0072] In another embodiment, the preset flushing rules can also establish a corresponding relationship between the feeding parameter input and the flushing parameter output through a data analysis model, a machine learning algorithm, a neural network algorithm, a clustering algorithm, an expert system, etc., so as to obtain a more accurate flushing parameter through the acquired feeding parameter. Exemplarily, the preset data analysis model is a data analysis model that is pre-trained based on at least one feeding parameter and is used to determine the flushing parameter based on at least one feeding parameter. After at least one of the feeding parameters is input into the preset data analysis model, the preset data analysis model performs data analysis and outputs a recommended flushing strategy. The present application can determine the flushing strategy output by the preset data analysis model as the flushing parameter.

[0073] In a possible example, after determining the first flushing parameter according to the feeding parameter and the preset flushing rule, the user can also adjust the first flushing parameter to make the first flushing parameter more consistent with the flushing requirement, thereby improving the flushing effect. Therefore, the control method of the present application can also include:

[0074] S10. Display the flushing parameter adjustment interface.

[0075] S20: receiving the user's input on the flushing parameter adjustment interface, and determining the second flushing parameter input by the user.

[0076] S30. Adjust the first flushing parameter according to the second flushing parameter input by the user.

[0077] Exemplarily, after determining the first flushing parameter, the flushing parameter adjustment interface can also be controlled to be displayed on the display screen of the nutrition infusion device, and the user can adjust the flushing parameter on the flushing parameter adjustment interface. Specifically, the second flushing parameter input by the user in the flushing parameter adjustment interface is received, so that the first flushing parameter is adjusted according to the second flushing parameter. Among them, the second flushing parameter can be an adjustment value or a target value. When the second flushing parameter is an adjustment value, the first flushing parameter is adjusted with the adjustment value indicated by the second flushing parameter to obtain a new flushing parameter; when the second flushing parameter is a target value, the value indicated by the second flushing parameter is determined as the new flushing parameter. The adjusted flushing parameters are more in line with the flushing needs of medical staff, and flushing the tube with the adjusted flushing parameters can have a better flushing effect, thereby improving the treatment effect.

[0078] For example, Figure 3 This is a schematic diagram of a flushing parameter adjustment interface provided in an embodiment of the present application. Figure 3As shown, a feeding parameter setting window 31 and a flushing parameter adjustment window 32 may be displayed in the flushing parameter adjustment interface 30. Feeding parameter information such as nutrient solution type, nutrient solution concentration, nutrient solution feeding amount, feeding mode, feeding speed, feeding time, and patient type are displayed in the feeding parameter setting window 31. When setting the feeding parameters, the user can directly click on the parameter itself "XXXX" 311 to enter the corresponding parameter setting value. After setting the parameters, if the parameter setting value is to be adjusted, it can be achieved by clicking on the "+" / "-" control 312 to increase / decrease the corresponding value, or clicking on the "Modify" control 313 of the feeding parameter, which is not limited in this application. After the user sets the feeding parameters, the flushing parameters displayed in the flushing parameter adjustment window 32 will be automatically filled. If the user wants to adjust the flushing parameters, he can directly click on the "Modify" control 321 of the flushing parameters in the interface to modify them, or directly click on the parameter itself "XXXX" 322 to enter the corresponding parameter adjustment value, or click on the "+" / "-" control 323 to increase / decrease the corresponding value, which is not limited in this application.

[0079] In some examples, Figure 3 The feeding parameter setting window 31 and the flushing parameter adjustment window 32 in the flushing parameter adjustment interface 30 may also display a feeding parameter "confirm" control 314 and a flushing parameter "confirm" control 324. After the user confirms the feeding parameter through the "confirm" control 314, the feeding parameter takes effect, and the flushing parameter is automatically determined according to the preset flushing rule of the present application; after the user confirms the first flushing parameter through the "confirm" control 324, the first flushing parameter takes effect, and the first flushing parameter can be used for flushing.

[0080] Among them, when adjusting the flushing parameters, the adjusted values ​​should be within the allowable range to avoid adverse consequences caused by misadjustment. Therefore, in some examples, after receiving the second flushing parameter input by the user in the flushing parameter adjustment interface, it is also possible to: determine whether the second flushing parameter input by the user exceeds the preset threshold, and when it is determined that the second flushing parameter input by the user exceeds the preset threshold, output a prompt message to prompt the user that the parameter adjustment is out of range, so that the user can correctly adjust the flushing parameters to ensure the accuracy of the flushing parameters. Among them, the prompt information can be a voice alarm, a flashing alarm light, a text prompt, an icon prompt, a highlight prompt, a pop-up prompt, etc., which is not limited by this application.

[0081] S203. Control the nutrition infusion device to perform flushing according to the first flushing parameter.

[0082] For example, after the control device of the nutrition infusion device of the present application determines the flushing parameters, at the time when flushing is required, the determined flushing parameters are used to control the nutrition infusion device to flush. For example, intermittent feeding may require flushing before and after each feeding, and continuous feeding may require flushing during the feeding process, which can be determined according to the specific feeding situation, and the present application does not limit it.

[0083] The control method of the nutrition infusion device provided in the embodiment of the present application includes: obtaining feeding parameters, determining a first flushing parameter according to the feeding parameters and a preset flushing rule, and controlling the nutrition infusion device to flush according to the first flushing parameter. In the present application, when setting parameters, medical staff only need to set the feeding parameters to automatically determine the corresponding flushing parameters, without having to manually set the flushing parameters, thereby improving the efficiency of parameter setting; in addition, compared with manually setting the flushing parameters, the accuracy of automatically determining the flushing parameters according to the feeding parameters is also higher, thereby improving the accuracy of the parameter setting, and thus also improving the accuracy of the flushing control.

[0084] Figure 4 The following is a flow chart of another method for controlling a nutrition infusion device provided in an embodiment of the present application. Figure 4 As shown, the control method of the nutrition infusion device provided in this embodiment includes:

[0085] S401, obtaining feeding parameters.

[0086] S402: Determine a first flushing parameter according to the feeding parameter and a preset flushing rule.

[0087] S403: Control the nutrition infusion device to perform flushing according to the first flushing parameter.

[0088] Exemplarily, the specific implementation of steps S401 to S403 is similar to that of steps S201 to S203, and will not be described in detail here.

[0089] S404: Obtain working status information of the nutrition infusion device.

[0090] For example, after setting the feeding parameters and flushing parameters, the control device of the nutrition infusion device of the present application can continue to control the nutrition infusion device to feed the nutrient solution. During the actual feeding process, the working state of the nutrition infusion device will change, and there will be a certain difference between the actual feeding parameters and the set target feeding parameters. In order to more accurately adjust the flushing parameters, during the feeding process, the control device of the nutrition infusion device of the present application can also obtain the actual working state information of the nutrition infusion device, so as to adjust the flushing parameters according to the actual feeding situation in the future to achieve a better flushing effect.

[0091] The working status information may include one or more of the following: feeding pause duration, manual flushing information, and pipeline blockage information; wherein the pipeline blockage information includes pipeline blockage frequency and / or pipeline blockage pressure value.

[0092] Exemplarily, the feeding pause duration refers to the duration of time that the medical staff manually controls the feeding pause according to the actual feeding situation and then manually starts the feeding. Manual flushing information refers to the information that the medical staff manually controls the nutrition infusion equipment to flush according to the actual feeding situation. Pipeline blockage refers to the phenomenon that the nutrient solution cannot be infused as normal due to blockage in the delivery pipeline. The degree of blockage can be determined by the pipeline blockage frequency and / or pipeline blockage pressure value.

[0093] For example, in the actual feeding process, according to the treatment needs, medical staff may suspend feeding or perform manual flushing and other operations. When the nutrient solution stays in the pipeline for more than a certain period of time, it may cause pipe blockage. When the pipeline is blocked or is about to be blocked, the pipeline blockage pressure value and / or pipeline blockage frequency will also change. When the pipeline blockage pressure value and / or pipeline blockage frequency reach the set threshold, it is necessary to adjust the subsequent flushing parameters to avoid serious pipe blockage and affect the feeding effect. After manual flushing, if the original flushing parameters are still used for flushing, it is possible to cause excessive flushing, leading to complications such as diarrhea. At this time, it is also necessary to adjust the subsequent flushing parameters to avoid excessive flushing. That is, when the working status information of the nutritional infusion device changes, the corresponding flushing parameters should also be adjusted to be more suitable for the actual feeding situation.

[0094] S405: Adjust the first flushing parameter according to the working status information and the preset parameter adjustment strategy.

[0095] Exemplarily, the control device of the nutrition infusion device of the present application can adjust subsequent flushing parameters according to the acquired working status information of the nutrition infusion device and the preset parameter adjustment strategy to obtain a better flushing effect.

[0096] Exemplarily, according to the working state information and the preset parameter adjustment strategy, the step of adjusting the first flushing parameter may include: when it is determined that the working state information satisfies the preset parameter adjustment condition, adjusting the first flushing parameter according to the working state information.

[0097] Exemplarily, when the working status information obtained is the feeding pause duration, the first flushing parameter can be adjusted according to the working status information and the preset parameter adjustment strategy: determine whether the feeding pause duration exceeds the preset value. If it is determined that the feeding pause duration exceeds the preset value, it indicates that there may be a risk of tube blockage. At this time, the nutrition infusion device can be controlled to flush immediately before starting feeding, and the subsequent flushing parameters can be adjusted, such as reducing the next flushing volume and flushing time, extending the next flushing interval, etc., to avoid excessive flushing in a short period of time.

[0098] Exemplarily, when the acquired working status information is manual flushing information, that is, when it is determined that the medical staff manually controls the nutrition infusion device to flush, in order to avoid excessive flushing in a short period of time, the first flushing parameter can be adjusted according to the working status information and the preset parameter adjustment strategy: adjusting the subsequent flushing parameters, for example, canceling the most recent flushing, or extending the next flushing interval, reducing the next flushing volume and flushing time, etc., so as to avoid excessive flushing in a short period of time.

[0099] Exemplarily, when the acquired working status information is pipeline blockage information, according to the working status information and the preset parameter adjustment strategy, the first flushing parameter can be adjusted as follows: according to the pipeline blockage information, the degree of pipeline blockage is determined, and the flushing parameter is adjusted based on the degree of pipeline blockage. For example, if it is determined that pipeline blockage or blockage warning has occurred or is about to occur based on the pipeline blockage frequency and / or the pipeline blockage pressure value, the nutrition infusion device is controlled to automatically start flushing to clear the pipeline in time and prevent pipe blockage; in addition, according to the specific values ​​of the pipeline blockage frequency and / or the pipeline blockage pressure value, the flushing interval time can be appropriately shortened, the flushing volume can be increased, etc., so as to reduce the occurrence of blockage. For example, when the values ​​of the pipeline blockage frequency and / or the pipeline blockage pressure value are large, the flushing interval time can be shortened, the flushing volume can be increased, etc., so as to reduce the occurrence of blockage.

[0100] Exemplarily, when it is determined that the working status information satisfies the pre-set parameter adjustment conditions, the first flushing parameter is adjusted according to the specific value of the working status information, and the nutritional infusion equipment is controlled to flush with the adjusted flushing parameter, thereby reducing the risk of tube blockage, avoiding excessive flushing in a short period of time, improving the accuracy of flushing control, and improving the treatment effect.

[0101] In a possible example, after adjusting the first flushing parameter according to the working status information and the preset parameter adjustment strategy, in order to facilitate medical staff to view the parameter adjustment record, conduct infusion review, and more accurately understand the flushing situation during the infusion process, the control method of the present application may also include:

[0102] Record the parameter adjustment details during the infusion process; wherein the parameter adjustment details include the reason for the flushing parameter adjustment and / or the flushing parameter adjustment time and / or the values ​​before and after the flushing parameter adjustment.

[0103] For example, by recording the parameter adjustment details, medical staff can more accurately understand the flushing conditions during the infusion process so as to subsequently set a more accurate flushing plan to provide better and better treatment services to the feeding subject.

[0104] The control method of the nutrition infusion device provided in the embodiment of the present application includes: obtaining feeding parameters, determining a first flushing parameter according to the feeding parameters and preset flushing rules, controlling the nutrition infusion device to flush according to the first flushing parameter, obtaining the working status information of the nutrition infusion device, and adjusting the first flushing parameter according to the working status information and the preset parameter adjustment strategy. Accordingly, after the user sets the feeding parameters, the present application can directly and automatically determine the flushing parameters according to the pre-set flushing rules, without the need for medical staff to manually set the flushing parameters, thereby improving the efficiency of parameter setting; in addition, the present application also adjusts the flushing parameters according to the actual feeding situation during the actual feeding process, thereby reducing the risk of tube blockage, avoiding excessive flushing in a short period of time, improving the accuracy of flushing control, and thus improving the treatment effect.
