The invention claims priority of Chinese Patent Application No. 202311409802.3, entitled “Nutrient Infusion Apparatus and Control Method Therefor” filed with the China National Intellectual Property Administration on October. 26, 2023, which is incorporated herein by reference in its entirety.
This invention generally relates to medical apparatus, and more particularly, to a nutrient infusion apparatus and a control method therefor.
During the process of enteral nutrition infusion, complications such as tube blockage and diarrhea are common. Flushing the tube can effectively prevent nasal feeding tube blockage and also help with hydration. However, excessive flushing within a short period may also lead to the occurrence of the complication diarrhea.
In the prior art, a nutrition infusion apparatus with automatic flushing functions can automatically flush the tube during the feeding process after determining the flushing parameters. This reduces the need for manual operations by medical staff while still achieving the tube-flushing effect.
However, the flushing parameters of existing nutrient infusion apparatus can only be set manually by the healthcare professional, and the efficiency of parameter setting is low. Moreover, it is not possible to adjust the flushing program according to the working status of the nutrient infusion apparatus during the actual feeding process, and there will still be a blockage of the tube or an excessive amount of flushing, which degrades the therapeutic effect.
Moreover, currently available nutrient infusion device require medical staff to set the flushing parameters manually, which results in low efficiency. Additionally, they cannot adjust the flushing program according to a working state of the nutrient infusion apparatus during the actual feeding process. This may still lead to tube blockage or excessive flushing, thus affecting the overall treatment effectiveness.

In a fifth aspect, the invention provides a computer program product comprising a computer program, the computer program, when executed by a processor, being configured to implement a method as previously described.
The invention provides a nutrient infusion apparatus and a control method therefor, including: acquiring a feeding parameter; automatically determining a first flushing parameter according to the feeding parameter and a preset flushing rule; and controlling the nutrient infusion apparatus to flush according to the first flushing parameter. Using the method of the invention, healthcare personnel, when performing parameter setting, only need to set the feeding parameter, and the corresponding flushing parameter can be determined automatically, without also having to set the flushing parameter manually, thereby improving the efficiency of parameter setting.

The accompanying drawings herein, which are incorporated into and form a part of the specification, illustrate embodiments consistent with the invention and are used in conjunction with the specification to explain the principles of the invention.
By means of the above accompanying drawings, definite embodiments of the invention are shown, and will be described in more detail later. These accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concepts of the invention for those skilled in the art by reference to particular embodiments.
Example embodiments will be described herein in detail, which are represented in the accompanying drawings. When the following description relates to the accompanying drawings, the same numerals in the different accompanying drawings indicate the same or similar elements unless otherwise indicated. The embodiments described in the following example embodiments do not represent all embodiments consistent with the invention. Rather, they are only examples of devices and methods consistent with some aspects of the invention as defined in the appended claims.
The terms “first”, “second”, “third”, “fourth” and the like, if any, in the specification and claims of the invention and the accompanying drawings described above are used to distinguish similar objects and need not be used to describe a particular order or sequence. It should be understood that the number used in the specification may be interchanged, where appropriate, so that the embodiments of the invention described herein may be practiced in an order other than those illustrated or described herein. In addition, the terms “include” and “have”, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product or apparatus including a series of steps or units need not be limited to those clearly listed, but may include other steps or units that are not clearly listed or that are inherent to the process, method, product or apparatus.
Tube flushing is routinely performed during enteral nutrition infusion to prevent tube blockage while also rehydrating a patient. Such tube flushing can effectively prevent blockage of the nasoenteric tube, but excessive tube flushing within a short period of time may also lead to diarrhea complications. Therefore, it is necessary to accurately control the flushing parameters to ensure therapeutic efficacy.
Currently available nutrient infusion apparatuses require medical staff to manually set the flushing parameters, which results in low efficiency. Additionally, they cannot adjust the flushing program according to a working state of the nutrient infusion apparatus during the actual feeding process. This may still lead to tube blockage or excessive flushing, thus affecting the overall treatment effectiveness.
In order to solve the above problems, the invention provides a method for controlling a nutrient infusion apparatus, in which the invention takes into account that the flushing of the nutrient infusion apparatus is closely related to the feeding process, and therefore associates the feeding parameters with the flushing parameters, so that after the user has set the feeding parameters, the flushing parameters are determined directly and automatically according to preset flushing rules, without staff having to manually set the flushing parameters. This improves the efficiency of parameter setting. In addition, the invention also obtains information on the working status of the nutrient infusion apparatus 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; this improves the therapeutic effect.
In order to solve the aforementioned problems, the invention provides a method for controlling the nutrient infusion apparatus. Considering the close relationship between the flushing process and the feeding process of the nutrient infusion apparatus, the feeding parameters are linked with the flushing parameters. After the user sets the feeding parameters, the flushing parameters are automatically determined based on preset flushing rules without needing manual input, thereby improving parameter-setting efficiency. Additionally, during the actual feeding process, the working state information of the nutrient infusion apparatus is acquired and is used to adjust the flushing parameters according to the real-time feeding conditions. This reduces the risk of tube blockage and prevents excessive flushing within a short period, ultimately improving the treatment effectiveness.
The technical solution of the invention and how it solves the above technical problems are described in detail below by means of specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes need not be duplicated in certain embodiments. Embodiments of the invention will be described below in conjunction with the accompanying drawings.
Firstly, the structure of the nutrient infusion apparatus involved in the invention is a briefly introduced.
As an example,
In addition, as shown in
Next, the process of how to control the nutrient infusion apparatus for feeding and flushing is described in detail.
As shown in
S201, feeding parameters are acquired.
As an example, when the nutrient infusion apparatus shown in
The feeding parameters characterize parameters related to the nutrient solution feeding process. For example, the feeding parameters may include at least one of the following: a nutrient solution type, a nutrient solution concentration, a nutrient solution feeding volume, a feeding mode, a feeding rate, a feeding time, a patient type, etc.
As an example, the healthcare personnel may, according to the actual nutrient infusion needs of the feeding subject, sequentially set the nutrient solution type, the nutrient solution concentration, the nutrient solution feeding volume, the feeding mode, the feeding rate, the feeding time, and the patient type of the nutrient solution to be infused into the feeding subject on the setting interface of the feeding parameter. The feeding mode may be continuous feeding or intermittent feeding.
As an example, in the continuous feeding mode, feeding is generally a continuous over a period of more than 24 h. Continuous feeding is better tolerated by patients with poor intestinal absorption ability or gastrointestinal dysfunction, and it is also a feeding mode that is more widely used in patients with severe clinical conditions. Intermittent feeding generally refers to a feeding mode that provides 4-6 feedings per day, each lasting 20-60 minutes, which is more in line with physiological characteristics, and facilitates the feeding subject to get out of bed or carry out activities such as treatment and examination. When setting the parameters, healthcare personnel can choose the appropriate feeding mode according to the physical condition of the feeding subject. that is, patient, and the treatment plan to be carried out. For example, if the feeding subject is a critically ill patient with poor intestinal absorption, continuous feeding may be selected to provide sufficient nutrition for the feeding subject. If the feeding subject needs to do supplementary training or needs to be examined at a specific time period, intermittent feeding may be selected to facilitate scheduling of the feeding subject.
In one possible example, the feeding parameters may also be indirectly determined by analyzing the nutrient infusion requirement information of the feeding subject and/or the feeding subject information and/or vital sign state parameters. The nutrient infusion requirement information may include at least one of the following: the nutrient solution type, the feeding mode, the feeding rate, the feeding volume, and the feeding time. The feeding subject information may include at least one of the following: a patient's body weight, body weight change, age, calorie consumption, height, gender, a patient type, and disease information. The vital sign state parameters may include at least one of an end-tidal carbon dioxide indication EtCO2, a hemodynamic indication, a blood glucose indication, a heart rate, a blood pressure, an electrocardiogram, a body temperature, an oxygen saturation, and a pulse. For example, instead of entering the feeding parameters themselves, the healthcare personnel may enter information about the nutrient infusion requirements of the feeding subject and/or the feeding subject information and/or the vital sign state parameters in the setting screen for the feeding parameter. This information may be obtained from any chosen source, such as, for example, the patient monitor, a Hospital Information System (HIS), a Clinical Information System (CIS), etc. The nutrient infusion apparatus may automatically analyze these parameters after acquiring them to determine the feeding parameters of the invention.
The invention does not impose restrictions on how the nutrient infusion apparatus determines the feeding parameters according to the nutrient infusion requirement information of the feeding subject and/or the feeding subject information and/or the vital sign state parameters. For example, the nutrient infusion demand information of the feeding subject and/or the feeding subject information and/or the vital sign state parameters may be input into a predetermined data analysis model, a neural network model, a clustering model, or the like, to determine that the parameters outputted by the model are the feeding parameters. Alternatively, the historical feeding parameters of the feeding subject may be retrieved, and then the nutrient infusion requirement information and/or the feeding subject information and/or the vital sign state parameters of the feeding subject may be compared and matched with the historical feeding parameters, and the historical feeding parameter with the highest match is determined to be the current feeding parameter. The nutrient infusion requirement information of the feeding subject and/or the feeding subject information and/or the vital signs state parameters may be analyzed in various ways, so that the feeding parameters can be determined.
S202, according to the feeding parameters and the preset flushing rule, the first flushing parameters are determined.
As an example, after acquiring the feeding parameters, the control device of the nutrient infusion apparatus of the invention can automatically generate a set of suitable flushing schemes according to the feeding parameters and the preset flushing rule, which has a corresponding first flushing parameter and which is a flushing default value. The healthcare personnel then only need to set the feeding parameters and do not need to set the flushing parameters. This improves the efficiency of parameter setting.
As an example, the flushing parameter characterizes the parameters associated with the flushing process. For example, the flushing parameter may include at least one of the following: a flushing mode, a flushing rate, a total flushing volume, a flushing time, a flushing volume per cycle, and a number of flushing cycles. The flushing mode may be pulsed flushing or steady flushing, which may, but need not, have a different flushing rate than for pulsed flushing.
As an example, pulsed flushing may be a flushing mode that uses push-and-stop flushing, which can make the flushing liquid generate positive and negative pressure so as to form a vortex in the cavity of the flushing tube. This then increases the thorough and uniform flushing of the tube (such as a catheter) wall, powerfully flushing the residual drug attached to the catheter wall, and reducing the occurrence of blockage more effectively. Uniform flushing is a flushing mode that provides a continuous, uniform flow of flushing fluid. The closer to the center axis of the tube, the greater the flow rate will be, and the closer to the wall, the smaller the flow rate will be. The flow rate along the tube wall will be close to zero, and the flushing effect will be limited. In determining the flushing mode, if the nutrient solution is viscous, and/or the nutrient solution concentration is larger, in order to achieve a better flushing effect and effectively avoid blocking the tube, the device may be set to the pulsed flushing mode. If it is determined that the feeding subject does not have a high demand for the flushing effect, and it is necessary to replenish water, the device may preferably be set to the uniform flushing mode.
In one embodiment, the preset flushing rule may be determined according to a correspondence between the feeding parameters and the flushing parameters, and the flushing parameters used for different feeding parameters may be different. Other flushing rules may instead be chosen, however. For example, when determining the flushing parameters, the flushing mode and the flushing rate may be set according to the nutrient solution type and/or the nutrient solution concentration. The flushing time and the flushing volume per cycle are determined according to the flushing total volume and the feeding mode. The flushing parameters corresponding to the feeding parameters of the different feeding subjects may be different, which should be considered in conjunction with the overall situation of the feeding subject. For example, when the nutrient solution with a nutrient solution type in the feeding parameters is relatively more viscous, and/or the nutrient solution concentration is large, then according to the preset flushing rule, a larger flushing rate, a larger total flushing volume, shorter flushing times, and a larger number of flushing cycles may be set. On the other hand, if nutrient solution with a nutrient solution type in the feeding parameters is dilute and/or the nutrient solution concentration is small, then, according to the preset flushing rule, a smaller flushing rate, a smaller total flushing volume, a smaller amount of flushing may be set. Of course, based on the preset flushing rule, corresponding flushing parameters may also be determined according to at least one of other feeding parameters (e.g., nutrient solution feeding volume, feeding mode, feeding rate, feeding time, patient type), etc.
For example, a mapping table characterizing the correspondence between each feeding parameter and each flushing parameter may be experimentally or computationally established. For example, the mapping table may include the correspondence between the nutrient solution type and the flushing mode, the correspondence between the nutrient solution concentration and the flushing rate, the correspondence between the feeding mode and the flushing time, and so on. When the nutrient solution type is chosen, the flushing mode may then be selected according to the correspondence between the nutrient solution type and the flushing mode in the mapping table. When the nutrient solution concentration is known, the flushing rate may also be set according to the correspondence between the nutrient solution concentration and the flushing rate in the mapping table, and so forth. Each parameter of the flushing parameter may thus be determined according to the information in the mapping table.
In addition, in another embodiment, the preset flushing rule may be chosen according to a formula that represents a functional relationship between one or more feeding parameters and each flushing parameter, in which the input parameter is one or more feeding parameters and the output function value is a flushing parameter. A plurality of formulas may be determined experimentally and/or theoretically and included in the preset flushing rule, with the output function value of each formula corresponding to a different flushing parameter. When one or more feeding parameters are obtained, they may then be substituted as parameters in the chosen formula and the corresponding flushing parameters can be calculated. Alternatively, the corresponding feeding parameters may also be calculated “inversely” according to the flushing parameters and the respective formula. functional relationship equation. For example, given the nutrient solution feeding volume and the feeding rate, the feeding time, that is, the duration of the feeding, can be calculated. When the feeding time exceeds a preset threshold, a flush cycle may be performed periodically, for example, once for every n hours of continuous feeding. Accordingly, given the feeding time and the number n, the number of flushing cycles can be calculated. For example, if the flushing rate should be m times the feeding rate, then after determining the feeding rate, it will be possible to calculate the flushing rate. For the feeding parameter and the flushing parameter, which have a functional relationship, the corresponding parameter values can be determined in this manner.
Further, in yet another embodiment, the preset flushing rule may also be a combination of the above mapping table and the respective formula. For example, when the user sets the nutrient solution type to be infused into the feeding subject on the parameter setting interface, then, given the correspondence between the nutrient solution type and the flushing mode in the mapping table, the proper flushing mode can be determined. When the nutrient solution concentration is set, according to the correspondence between the nutrient solution concentration and the flushing rate in the mapping table, the flushing rate can be determined, and so forth. Thus, the flushing parameters calculated by the respective formula can also be determined. Accordingly, a flushing parameter matching the feeding parameter may be determined by correspondence and the functional relationship existing between the parameters.
In still another embodiment, the preset flushing rule may also be a correspondence between the input of the feeding parameters and the output of the flushing parameters established by a data analysis model, a machine learning algorithm, a neural network algorithm, a clustering algorithm, an expert system, or the like. Thus, a more accurate flushing parameter can be determined according to the acquired feeding parameters and the above preset flushing rule. As an example, the predetermined data analysis model may be pre-trained on at least one of the feeding parameters and configured to determine the flushing parameters according to the at least one of the feeding parameters. After inputting at least one of the feeding parameters into the predetermined data analysis model, the predetermined data analysis model may perform the data analysis to output a recommended flushing strategy, and the flushing strategy output by the predetermined data analysis model may be used as a flushing parameter in this invention.
In one possible example, after determining the first flushing parameter according to the feeding parameters and the preset flushing rule, the user may also adjust the first flushing parameter to make the first flushing parameter more consistent with the flushing demand, thereby improving the flushing effect. Therefore, the control method of the invention may also include the following steps.
As an example, after determining the first flushing parameter, the flushing parameter adjustment interface may also be controlled to be displayed in a display of the nutrient infusion apparatus, and the user may adjust the flushing parameter on the flushing parameter adjustment interface. In an embodiment, a second flushing parameter input by the user at the flushing parameter adjustment interface is received, so as to adjust the first flushing parameter according to the second flushing parameter. The second flushing parameter may 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 set to be the new flushing parameter. The adjusted flushing parameter may be more in line with the flushing needs of the healthcare personnel, and flushing the tube with the adjusted flushing parameter can have a better flushing effect, thereby improving the treatment effectiveness.
As an example,
In some examples, the feeding parameter setting window 31 and the flushing parameter adjustment window 32 in the flushing parameter adjustment interface 40 shown in
In this regard, when adjusting the flushing parameters, the adjustment values should be within a permissible range so as to avoid adverse consequences caused by misadjustment. Thus, in some examples, after receiving the second flushing parameter input by the user in the flushing parameter adjustment interface, the system determines whether the second flushing parameter input by the user exceeds the preset threshold value, and, if it does, a prompt message is output, so as to indicate to the user that the parameter adjustment is out of range. The user may then correctly adjust the flushing parameter, thereby ensuring the accuracy of the flushing parameter. The prompting information may be a voice alarm, an alarm light blinking, a text prompt, an icon prompt, a highlight prompt, a pop-up window prompt, etc.
S203, according to the first flushing parameter, the nutrient infusion apparatus is controlled to flush.
As an example, when the control device of the nutrient infusion apparatus of the invention determines the flushing parameter, the determined flushing parameters are used to control the nutrient infusion apparatus for flushing at the moment when flushing needs to be performed. For example, intermittent feeding may require flushing before and after each feeding separately, and continuous feeding may require flushing during feeding, which may be determined according to the specific feeding situation.
Embodiments of the invention provide a method for controlling a nutrient infusion apparatus, including: acquiring a feeding parameter; automatically determining a first flushing parameter according to the feeding parameter and a preset flushing rule; and controlling the nutrient infusion apparatus to flush according to the first flushing parameter. Using the method of the invention, healthcare personnel, when performing parameter setting, only need to set the feeding parameter, and the corresponding flushing parameter can be determined automatically, without having to set the flushing parameter manually, thereby improving the efficiency of parameter setting. Furthermore, relative to manually setting the flushing parameter, the accuracy of automatically determining the flushing parameter according to the feeding parameter is also higher, which improves the accuracy of parameter setting, thereby improving the accuracy of the flushing control.
S401, feeding parameters are acquired.
S402, a first flushing parameter is determined according to the feeding parameters and a preset flushing rule.
S403, the nutrient infusion apparatus is controlled to flush according to the first flushing parameter.
As an example, the specific realization of steps S401 to S403 is similar to step S201 to step S203, and will not be repeated herein.
S404: working state information of the nutrient infusion apparatus is acquired.
As an example, after setting the feeding parameters and the flushing parameters, the control device of the nutrient infusion apparatus of the invention may continue to control the nutrient infusion apparatus to carry out nutrient solution feeding. During the actual feeding process, the working state of the nutrient infusion apparatus will change, and there will be some 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 can also obtain the practical working state information of the nutrient infusion apparatus, so that it can subsequently adjust the flushing parameters to achieve a better flushing effect.
The working state information may include at least one of the following: feeding pause duration, manual flushing information, and tube blockage information. The tube blockage information includes a tube blockage frequency and/or a tube blockage pressure value.
As an example, the feeding pause duration refers to the a duration experienced by the healthcare personnel while manually controlling the feeding pause and then manually starting the feeding according to the actual feeding situation. Manual flushing information is the information that the healthcare personnel manually controls to cause the nutrient infusion apparatus to flush according to the actual feeding situation. Tube blockage refers to when the nutrient solution cannot be infused according to normal conditions due to the existence of blockage in the delivery tubing; the degree of blockage may be determined by the tube blockage frequency and/or the tube blockage pressure value.
As an example, during the actual feeding process, depending on the therapeutic needs, the healthcare personnel may suspend the feeding or perform operations such as manual flushing. When the nutrient solution stays in the tube for more than a certain duration, it may cause tube blockage, and when the tube is blocked or is about to be blocked, the tube blockage pressure value and/or the tube blockage frequency will also change. When the tube blockage pressure value and/or tube blockage frequency reaches a preset threshold, it is necessary to adjust the subsequent flushing parameters in order to avoid serious blockage that may affect the feeding effect. After manual flushing, if the original flushing parameters are still used for flushing, it is possible for this to cause excessive flushing, resulting in diarrhea and other complications. It is then also necessary to adjust the subsequent flushing parameters to avoid excessive flushing. That is, when the working state information of the nutrient infusion apparatus changes, the corresponding flushing parameters should also be adjusted to be more applicable to the actual feeding situation.
S405: According to the working state information and the preset parameter adjustment strategy, the first flushing parameter is adjusted.
As an example, the control device of the nutrient infusion apparatus of the invention may adjust the subsequent flushing parameters according to the obtained working state information of the nutrient infusion apparatus and the preset parameter adjustment strategy, so as to obtain a more effective flushing.
As an example, the step of adjusting the first flushing parameter according to the working state information and the preset parameter adjustment strategy may include: adjusting the first flushing parameter according to the working state information when it is determined that the working state information satisfies the preset parameter adjustment condition.
As an example, when the acquired working state information is a feeding pause duration, the step of adjusting the first flushing parameter according to the working state information and the preset parameter adjustment strategy may be as follows: determining whether the feeding pause duration exceeds a preset value, and if it is determined that the feeding pause duration exceeds the preset value, an indication is generated that there may be a risk of blockage in the tube. In this circumstance, flushing may be controlled so as to take place immediately prior to the start of feeding by the nutrient infusion apparatus, and subsequent flushing parameters are adjusted, such as reducing the next flushing volume and flushing duration, extending the next flushing time, or the like, in order to avoid excessive flushing in a short period of time.
As an example, when the acquired working state information is manual flushing information, i.e., when it is determined that there is a situation in which the healthcare personnel should manually control the nutrient infusion apparatus to flush manually, in order to avoid excessive flushing within a short period of time. The step of adjusting the first flushing parameter according to the working state information and the preset parameter adjustment strategy may then be as follows: adjusting the subsequent flushing parameter, such as canceling the last flushing, extending the next flushing time, or, reducing the next flushing volume and flushing duration, so as to avoid excessive flushing within a short period of time.
As an example, when the acquired working state information is the tube blockage information, the step of adjusting the first flushing parameter according to the working state information and the preset parameter adjustment strategy may be as follows: according to the tube blockage information, the degree of tube blockage is determined, and the flushing parameters are adjusted according to the degree of tube blockage. For example, if it is determined that a tube blockage or a blockage warning has occurred or is about to occur according to the tube blockage frequency and/or the tube blockage pressure value, the nutrient infusion apparatus may be controlled to automatically start flushing to timely unblock the tube to prevent blockage. In addition, the flushing time may be appropriately shortened and the flushing volume increased according to a specific value of the tube blockage frequency and/or a specific value of the tube blockage pressure, so as to minimize the occurrence of the blockage. For example, when the tube blockage frequency and/or the tube blockage pressure value is large, the flushing time may be shortened and the flushing volume increased, so as to reduce the occurrence of blocking.
As an example, when it is determined that the work state information satisfies the preset parameter adjustment conditions, the first flushing parameters may be adjusted according to the specific value of the work state information, and the nutrient infusion apparatus may be controlled to flush with the adjusted flushing parameter, so as to reduce the risk of tube blockage, and also to avoid excessive flushing within a short period of time, thereby improving the accuracy of the flushing control, and also improving the therapeutic effect.
In one possible example, after adjusting the first flushing parameters according to the work state information and the preset parameter adjustment strategy, in order to make it easier for the healthcare professional to view the parameter adjustment record, conduct the infusion review, and more accurately understand the flushing situation during the infusion process, the method of the invention may also include the following step:
Details of the parameter adjustment during the infusion process are recorded. The parameter adjustment details include at least one the following: a flushing parameter adjustment reason, a flushing parameter adjustment time, values before and after the flushing parameter adjustment.
As an example, with the recorded parameter adjustment details, the healthcare personnel can more accurately understand the flushing situation during the infusion process, so as to subsequently set up a more accurate flushing regimen, in order to provide better therapeutic services to the feeding subject.
The method for controlling a nutrient infusion apparatus provided by the embodiment of the invention includes: acquiring feeding parameters, automatically determining a first flushing parameter according to the feeding parameters and a preset flushing rule, controlling the nutrient infusion apparatus to flush according to the first flushing parameter, acquiring working state information of the nutrient infusion apparatus, and adjusting the first flushing parameter according to the working state information and the preset parameter adjustment strategy. Accordingly, after the user sets the feeding parameters, the invention can directly and automatically determine the flushing parameters according to the preset flushing rules, without the need for the healthcare personnel to manually set the flushing parameters again, which improves the efficiency of parameter setting. Furthermore, the invention may adjust the flushing parameters according to the actual feeding situation during the actual feeding process, thereby reducing the risk of tube blockage, and avoiding excessive flushing within a short period of time, thereby improving the flushing control accuracy, and also improving the therapeutic effect.
As an example, the specific realization of steps S501-S502 is similar to steps S201-S202, the specific realization of steps S50-S504 is similar to steps S404-S405, and the specific realization of step S505 is similar to step S203, and will not be repeated herein.

Accordingly, after the user sets the feeding parameters, the invention can directly and automatically determine the flushing parameters according to the preset flushing rules, without the need for the healthcare personnel to manually set the flushing parameters again, which improves the efficiency of parameter setting.
