The terms “first”, “second”, “third”, “fourth”, etc., if any, in the specification and claims of the present application and the accompanying drawings are used to distinguish similar objects and need not be used to describe a particular order or sequence. It should be understood that the data so used may be interchangeable, where appropriate, so that the embodiments of the present invention described herein can, for example, be practiced in an order other than those illustrated or described herein. In addition, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive embodiments, e.g., processes, methods, systems, products or devices that comprise 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 those processes, methods, products or devices.
It should be noted that the user information (including, but not limited to, user device information, user personal information) and data (including, but not limited to, data used for analysis, stored data, displayed data) involved in this invention are authorized by the user or sufficiently authorized by the parties, and the collection, use, and processing of the relevant data comply with the relevant laws, regulations and standards, and provide a corresponding operation portal for users to choose to authorize or refuse.
A nutrient solution is fed to provide subjects such as patients with sufficient nutrients to support their life activities and help their condition recover. Subject information such as weight change, age, and calorie consumption are important factors to focus on in nutrient feeding, and they have a significant impact on the patient's nutrient needs and feeding regimen. In addition, the patient's vital sign status parameter during the infusion process indicates the patient's nutrient tolerance to a certain extent, and only when the vital signs remain stable can the patient tolerate the process of nutrient intake, thus ensuring the effective absorption and utilization of nutrients. Therefore, when determining the parameters of nutrient infusion, the subject information and the vital sign state should be considered comprehensively.
However, at present, nutrient infusion parameters are usually determined by professional nutritionists, who integrate and formulate personalized nutrient feeding programs according to doctor's instructions and the patient's own basic information, vital signs status and other information, in order to provide appropriate nutrient support, and regularly check the performance of the subject's vital signs in the process of nutrient feeding to adjust the parameters in order to provide better nutrient infusion services to patients as much as possible. However, this parameter determination method relies heavily on the experience and ability of the nutritionist, the accuracy of the data is not guaranteed, and it is not applicable to home scenarios. Besides, it is often difficult for the caregiver and family members to set up a reasonable feeding strategy according to the patient's specific situation and vital signs, and the degree of automation and practicability is limited, so that it cannot provide better nutrient infusion for the subject.
In order to solve the above problems, the invention provides a nutrient infusion control method, taking into account that the absorption and utilization of nutrition is strongly related to the information of the subject and the vital signs of the subject. Therefore, in this invention, nutrient infusion parameters are automatically determined directly according to at least one of the nutrient infusion demand information, the information of the subject, and the current parameters of the vital signs status. Through a data analysis model or by comparing the data with a historical feeding strategy, nutrient infusion parameters are automatically determined, and the nutrient infusion parameters are used to control the nutrient infusion device for nutrient infusion. Accordingly, the determination of the nutrient infusion parameters is no longer solely dependent on the nutritionist, the data accuracy is higher, and it is applicable to various scenarios, which is more practical. Furthermore, the invention can also adjust the parameters according to the actual feeding situation during the infusion process, in order to be more suitable for the subject, and to provide a better nutrient infusion for the subject.
The technical solution of the invention and how the technical solution of the invention solves the above technical problems are described in detail with reference to the following specific embodiments, which may be combined with each other, and the same or similar concepts or processes may not be repeated in certain embodiments. Embodiments of the invention will be described below in conjunction with the accompanying drawings.
The subject patient's vital sign status parameter may be acquired by the monitor/monitoring module, the subject information may be acquired by the hospital information system or the clinical information system, and the nutrient infusion demand information may be acquired by the nutrient system software. The nutrient system software may determine a first nutrient infusion parameter according to at least one of the nutrient infusion demand information, the subject information, and the vital sign status parameter. The nutrient infusion device may be controlled to perform nutrient infusion according to the first nutrient infusion parameter. It should be noted that the specific structure of the nutrient infusion device is not limited in this invention.
As an example,
As shown in
S501, at least one of nutrient infusion demand information, subject information, and vital sign status parameter of a current subject are acquired.
As an example, before performing the nutrient infusion, the nutrient infusion control device of the invention first needs to acquire at least one of: the nutrient infusion demand information, the subject information, and the vital sign status parameter of the current subject.
The nutrient infusion demand information indicates the nutrient feeding demand of the healthcare personnel for the subject, which may be input by the healthcare personnel, family members and other personnel according to the practical demand, or may be inputted from other systems. As an example, the nutrient infusion demand information may include one or more of: a nutrient solution type, a feeding mode, a feeding rate, a feeding amount, a feeding time, and the like.
The subject information characterizes basic information about the individual patient, which may be retrieved from a hospital information system HIS or a clinical information system CIS. For example, the subject information may include one or more of: the patient's weight, weight change, age, calorie consumption, height, gender, patient type, and information on the diseases suffered by the patient.
During the nutrient feeding process, changes in the patient's basic personal information need to be closely monitored to determine if nutrient intake is appropriate. For example, if weight loss persists, it may indicate inadequate nutrient intake, requiring an increase in nutrient intake or an adjustment of the nutrient formula. On the contrary, if weight gain persists, there may be a problem of overfeeding, requiring an appropriate reduction in calorie intake. In some examples, there are differences in the nutrient needs and tolerance of patients of different ages. Young children and the elderly have relatively weaker digestive and immune systems and require more carefully selected feeding regimens and nutrient formulas. In some examples, some special diseases such as diabetes mellitus, renal insufficiency and other conditions also require special attention to the dietary composition and nutrient intake of patients. In some examples, the calorie consumption required by a patient depends on his/her physical condition, activity level, and medical condition. If the calorie intake is insufficient, it may lead to malnutrition and decreased immunity, whereas if the calorie intake is too high, it may lead to long-term complications such as obesity and cardiovascular disease. It is evident that information about the feeding goal is crucial for infusion control.
The vital sign status parameter characterizes the actual physical condition of the user, and the stability of vital signs is the basis for nutrient feeding. The process of nutrient intake may, for example, only be tolerated by the patient if the vital signs remain stable, thus ensuring effective absorption and utilization of nutrients. The vital sign status parameter may be acquired by monitoring with devices such as monitors/monitoring modules. For example, the vital sign status parameter may include one or more of: an end-expiratory carbon dioxide indicator EtCO2, a hemodynamic indicator, a blood glucose indicator, a heart rate, a blood pressure, an electrocardiogram, a body temperature, an oxygen saturation, and a pulse. The information including body temperature, heart rate and blood pressure in the vital sign status parameter can reflect the overall health status of the patient, which is conducive to understanding the nutrient needs of the patient and facilitating the adjustment of the amount and type of nutrient intake. The changes in vital signs can also reflect the metabolic status and intestinal function of the patient, e.g., an elevated temperature may indicate infection, and an accelerated heart rate and rapid respiration may indicate hypoxia. Attention to these vital signs status changes can provide patients with a better nutrient infusion plan to ensure the effective absorption and utilization of nutrition.
S502, the first nutrient infusion parameter is determined according to at least one of the nutrient infusion demand information, the subject information, and the vital sign status parameter.
As an example, after the nutrient infusion control device of this invention acquires at least one of the nutrient infusion demand information, the subject information, and the vital sign status parameter of the current subject, the first nutrient infusion parameter may be determined according to the acquired information. The first nutrient infusion parameter refers to parameter information related to the infusion, and may include one or more of: a nutrient solution type, an infusion mode, an infusion rate, an infusion volume, and the like. When the feeding mode is intermittent infusion, the first nutrient infusion parameter may also include information such as a single infusion volume, an infusion time of each time, an infusion rate of each infusion, and an interval time, which is not limited in this invention.
In addition, the invention does not limit how the first nutrient infusion parameter can be determined according to at least one of the nutrient infusion demand information, the subject information, and the vital sign status parameter. In one example, the step of determining the first nutrient infusion parameter according to at least one of the nutrient infusion demand information, the subject information, and the vital sign status parameter may include the following steps.
The at least one of the nutrient infusion demand information, the subject information, and the vital sign status parameter are inputted into a predetermined data analysis model, and an infusion strategy output by the predetermined data analysis model is determined as the first nutrient infusion parameter.
As an example, the predetermined data analysis model may be a data analysis model pre-trained for determining a nutrient infusion parameter according to at least one of: the nutrient infusion demand information, the subject information, and the vital sign status parameter of the subject. After the nutrient infusion demand information, the subject information, and the at least one of the vital sign status parameter are input into the predetermined data analysis model, the predetermined data analysis model will output a recommended infusion strategy after data analysis, and the invention may determine that the infusion strategy output by the predetermined data analysis model is the first nutrient infusion parameter.
In addition to determining the first nutrient infusion parameter using the method of the above-described predetermined data analysis model, in other embodiments, a correspondence between the inputs and outputs may be established by a machine learning algorithm, a neural network algorithm, a clustering algorithm, an expert system, or the like, so as to acquire a more accurate first nutrient infusion parameter by means of the acquired nutrient infusion demand information, the subject information, and the vital sign status parameter.
For example, if the first nutrient infusion parameter is determined according to the nutrient infusion demand information, then after acquiring the nutrient infusion demand information, the type of nutrient solution in the nutrient infusion demand information is determined to be the type of nutrient solution in the first nutrient infusion parameter, the feeding rate is determined to be the infusion rate, the feeding amount is determined to be the infusion amount, and so on. The first nutrient infusion parameter may be determined directly or indirectly according to the parameters related to the nutrient infusion demand information.
If the first nutrient infusion parameter is determined according to the subject information, the age, gender, patient type, and disease information of the patient in the subject information are extracted, and the first nutrient infusion parameter matching the subject information may be selected according to a preset feeding treatment program. If the subject is a child or an elderly person, the type of nutrient solution, the feeding rate and the infusion mode suitable for the child or the elderly may be selected according to the preset feeding treatment program. If the subject is an obese patient, however, a nutrient solution with lower calories and the infusion volume that is less than that of the normal subject may be selected.
In addition, during the process of feeding, the vital sign information of the subject can be acquired by the monitoring device, and the first nutrient infusion parameters can be determined according to the vital sign status information. For example, when the blood glucose value and the rate of change of the blood glucose of the subject are detected, the infusion rate and the infusion volume of the first nutrient infusion parameter can be determined accordingly. Of course, it is also possible to acquire other vital sign information of the subject other than blood glucose to determine the first nutrient infusion parameters; the examples given here are not an exhaustive list.
If the first nutrient infusion parameters are determined according to the nutrient infusion demand information and the subject information, the feeding rate in the nutrient infusion demand information may be determined to be an initial value of the infusion rate. The feeding volume may then be determined to be an initial value of the infusion volume. Thereafter, the infusion rate may be adjusted according to the age of the subject, and the infusion volume may be adjusted according to the calorie consumption of the subject, the body weight, and the change in body weight, and the like. For example, if the subject is elderly, the infusion rate may be adjusted downward. If the subject's calorie consumption is low and the subject is overweight, the infusion volume may be reduced. Similarly, each of the first nutrient infusion parameters is determined as above.
If the first nutrient infusion parameters are determined according to the nutrient infusion demand information, the subject information, and the vital sign status parameter, the initial value of the first nutrient infusion parameters may be determined according to the nutrient infusion demand information, and the initial value may be adjusted according to the subject information. And next, the start time of infusion may be adjusted according to the heart rate, the blood pressure, the electrocardiogram, and the pulse, and the infusion rate may be adjusted according to the end-of-expiration carbon dioxide index, the hemodynamic index, the blood glucose index, the body temperature, and oxygen saturation. For example, if the end-expiratory carbon dioxide index is low and the hemodynamic index is low, the infusion rate may be reduced to ensure that the subject can tolerate the nutrient intake. Similarly, each of the first nutrient infusion parameters is determined as above.
In summary, when analyzing and determining the nutrient infusion parameters, the relationships among the parameters should be considered comprehensively, and the effect of each parameter on the subject should be confirmed, so as to determine a more accurate nutrient infusion parameter, thereby providing the subject with more reasonable nutrition.
In some examples, the step of determining the first nutrient infusion parameter according to at least one of the nutrient infusion demand information, the subject information, and the vital sign status parameter may include the following steps.
Historical feeding parameters of the current subject are retrieved; the nutrient infusion demand information, the subject information, and the vital sign status parameter are compared and matched with the historical feeding parameters, and the historical feeding parameter with the highest degree of matching is determined as the first nutrient infusion parameter.
As an example, the historical feeding parameters of the current subject may be stored in advance in a database, and these historical feeding parameters may be feeding parameters that have been previously infused for the subject. When determining the first nutrient infusion parameter, the nutrient infusion control device of the invention calls up the historical feeding parameters of the current subject, and compares and matches the information acquired in step S501 with the historical feeding parameters retrieved. A matching degree with each historical feeding parameter may be calculated separately, and then the historical feeding parameter with the highest degree of matching is determined as the first nutrient infusion parameter.
When the first nutrient infusion parameter is determined by matching with the historical feeding parameters, if the first nutrient infusion parameter is displayed, the corresponding matching degree, selected times of use, and other index information may also be displayed, so that the user may better assess the applicability and effectiveness of the first nutrient infusion parameter when it is used as a data reference.
As an example, the first nutrient infusion parameter determined in the above manner may be used as a recommended value of the infusion parameter for the decision maker to use as a data reference, and the nutrient infusion device may be controlled to perform nutrient feeding according to the parameter determined by the decision maker after the decision maker has made a decision. Alternatively, the nutrient infusion may be controlled directly according to the first nutrient infusion parameter, and the invention does not impose any limitation.
Thus, in some possible examples, after determining the first nutrient infusion parameter, the nutrient infusion control method of the invention may further include the following steps.
S1, the first nutrient infusion parameter is displayed.
S2, a confirmation operation from the user is received to accept and apply the first nutrient infusion parameter.
As an example, after determining the first nutrient infusion parameter, the first nutrient infusion parameter may also be displayed in a display interface, and the display interface may also have a parameter confirmation control. After the user operates the confirmation control, the first nutrient infusion parameter may be used for nutrient infusion control. In this embodiment, after the nutrient infusion control device determines the first nutrient infusion parameter, the healthcare personnel should decide whether to authorize the confirmation, and the feeding is started only after manually confirming that the first nutrient infusion parameter meets the feeding requirements, so as to ensure the safety of the nutrient infusion process.
As an example,
In some possible examples, when the first nutrient infusion parameters serve as recommended values for the infusion parameters, the user may also adjust the infusion parameter to determine more reasonable infusion parameters. Thus, after determining the first nutrient infusion parameter, the nutrient infusion control method of the invention may further include the following steps.
S10, an interface for adjusting the nutrient infusion parameters is displayed.
S20, the user's input in the interface for adjusting the nutrient infusion parameters is received, and the second nutrient infusion parameter is determined.
S30, the first nutrient infusion parameters are adjusted according to the second nutrient infusion parameter input by the user.
As an example, after determining the first nutrient infusion parameters, an interface for adjusting the nutrient infusion parameters may also be displayed on the display screen. The interface for adjusting the nutrient infusion parameters may display the determined first nutrient infusion parameters, and the user may then input the second nutrient infusion parameter in this interface. The first nutrient infusion parameters may then b adjusted according to the second nutrient infusion parameter input by the user. The second nutrient infusion parameter may be an adjustment value or a target value. When the second nutrient infusion parameter is an adjustment value, the first nutrient infusion parameter is adjusted with the adjustment value indicated by the second nutrient infusion parameter to acquire the new nutrient infusion parameter. When the second nutrient infusion parameter is a target value, the value indicated by the second nutrient infusion parameter is determined to be the new nutrient infusion parameter; the adjusted nutrient infusion parameter is then more consistent with the feeding demand.
As an example, when the user enters the second nutrient infusion parameter in the interface for adjusting the nutrient infusion parameters, the user may directly click on the first nutrient infusion parameter in order to modify it. Alternatively, the user may click on the modification control on this interface for modification, and in the modification mode, the user may directly click on the increase/decrease preset amount button, or, for example, enter the value of the second nutrient infusion parameter.
In some possible examples, an automatic reminder may also be issued to prompt the healthcare worker for parameter adjustment and verification when parameter adjustment is required. The reminder may be in the form of a voice alarm, a flashing alarm light, etc., After the reminder is issued, the interface for adjusting the nutrient infusion parameters may be displayed for the user to make parameter adjustments.
As an example,
As an example,
When adjusting the nutrient infusion parameter as described above, the adjusted value should be within a permissible range so as to avoid undesirable consequences caused by misadjustment. Thus, in some examples, after receiving the second nutrient infusion parameter inputted by the user in the interface for adjusting the nutrient infusion parameters, the method may further include: determining whether the second nutrient infusion parameter input by the user exceeds a preset threshold value. When it is determined that the second nutrient infusion parameter input by the user exceeds the preset threshold value, a prompting message may be output to prompt the user that the parameter adjustment is out of range, so as to enable the user to correctly adjust the nutrient infusion parameter to ensure that the nutrient infusion parameters are accurate. The prompting information may be a voice alarm, an alarm light flashing, a text prompt, an icon prompt, a highlight prompt, a pop-up window prompt, and the like, and the invention does not impose any limitation.
S503 (
As an example, when the first nutrient infusion parameter is determined, the nutrient infusion control device of the invention controls the nutrient infusion device to perform the nutrient infusion according to the determined first nutrient infusion parameter, thereby completing the feeding of the subject.
The nutrient infusion control method provided by an embodiment of the invention includes: acquiring at least one of nutrient infusion demand information, subject information, and vital sign status parameter of a current subject; determining a first nutrient infusion parameter according to at least one of the nutrient infusion demand information, the subject information, and the vital sign status parameter; and performing a nutrient infusion according to the first nutrient infusion parameter. In the invention, the first nutrient infusion parameter is quickly and automatically determined directly according to at least one of the nutrient infusion demand information, the subject information, and the vital sign status parameter. This approach reduces reliance on nutritionists, enhances data accuracy, and improves the precision of nutrient infusion control. Furthermore, this method is applicable to various practical scenarios, allowing for rapid and accurate determination of the first nutrient infusion parameters even in home environments, and thus controlling the nutrient infusion device with higher practicality.
S901, at least one of: nutrient infusion demand information, subject information, and vital sign status parameter of the current subject are acquired.
S902, a first nutrient infusion parameter is determined according to at least one of: the nutrient infusion demand information, the subject information, and the vital sign status parameter.
S903, the nutrient infusion is performed according to the first nutrient infusion parameter.
The specific realization of step S901 to step S903 is similar to step S501 to step S503, and will not be repeated here.
S904, vital sign status parameters and infusion parameters of the current subject are acquired during the nutrient infusion process.
As an example, in practice, during the feeding process, the vital signs of the subject will change, and the actual infusion parameters will differ from the first nutrient infusion parameters previously determined, when the changes in these parameters will have a certain effect on the infusion effect. For this reason, in order to improve the infusion effect and ensure effective absorption and utilization of nutrients, the nutrient infusion control device of the invention can also acquire the vital sign status parameter and the infusion parameters of the current subject during the nutrient infusion process, so as to adjust the first nutrient infusion parameters according to the real-time state of the current subject, in order to make the infusion control more accurate.
S905, the first nutrient infusion parameter is adjusted according to the preset parameter adjustment strategy when it is determined that the vital sign status parameter and/or the infusion parameter satisfy a preset parameter adjustment condition.
As an example, when adjusting the first nutrient infusion parameter, the nutrient infusion control device of this invention may determine whether the vital sign status parameter and/or the infusion parameter satisfy the preset parameter adjustment conditions. If it is determined that the vital sign status parameter and/or the infusion parameter satisfy the preset parameter adjustment condition, then the first nutrient infusion parameter is adjusted according to the preset parameter adjustment strategy. The parameter adjustment conditions and the parameter adjustment strategy may be set according to the practical situation, and the invention does not impose any limitation.
The key to controlling the nutrient solution input lies in the precise adjustment of the infusion rate or the pump speed. When the subject cannot tolerate the preset target infusion rate, the practical infusion rate should be reduced to avoid an adverse reaction, and when the general condition of the subject is good, the system can gradually increase the infusion rate until the preset target infusion rate is reached, so as to ensure that the expected feeding goal is accomplished within the expected time.
As an example, the infusion rate may be related to a plurality of parameters, and each factor should be considered comprehensively when adjusting the infusion rate, which may be adjusted using the following adjustment formula:
υ2 represents the adjusted infusion rate, Infosubject represents subject information (e.g., subject's weight, weight change, age, calorie consumption, etc.), Entsolution represents the type of nutrient solution, EtCO2 represents the end-expiratory carbon dioxide index, IHDN represents the hemodynamic index, BG represents the blood glucose index, and Δυ represents the difference between the current actual infusion rate and the current preset target infusion rate, and ΔV represents the difference between the current actual infused volume and the current theoretical volume that should be infused. The adjustment formula is an empirical formula derived according to clinical experience, and an optimal adjustment speed υ2 may be derived by performing a differential analysis according to these parameters.
When adjusting the infusion rate according to the above information, it should be taken into account that the end-expiratory carbon dioxide indicator EtCO2 may reflect the circulatory status of the patient, and a low end-expiratory carbon dioxide indicator EtCO2 may reflect hypocapnia, which has deleterious effects such as low blood pressure due to peripheral vasodilatation, insufficient perfusion of the tissues, cardiac arrhythmia, constriction of the cerebral vasculature and decreased cognitive ability. A faster nutrient feeding rate may exacerbate these symptoms when values of the end-expiratory carbon dioxide indicator EtCO2 are below the preset threshold, and therefore, the feeding rate needs to be lower at this time.
In some examples, the hemodynamic index IHDN includes pressure parameters, flow parameters, and volumetric parameters, etc., the combination of which can reflect the patient's hemodynamic status. When the patient has hypotension, tachycardia or bradycardia and other hemodynamic instability, the gastrointestinal tract may be ischemic or under-perfused. At such time, it is necessary to lower the feeding rate to avoid possible triggering of gastrointestinal intolerance or other complications, in order to reduce the burden on the gastrointestinal tract.
In some examples involving the blood glucose indicator BG, high blood glucose may lead to gastrointestinal dysfunction and affect intestinal absorption and digestion. Therefore, for patients with unstable blood glucose control, a lower feeding rate should preferably be used, especially for nutrient solutions with high sugar content.
In addition, according to the difference Δυ between the current actual infusion rate and the current preset target infusion rate, and the difference ΔV between the current actual infused volume and the current theoretical volume that should be infused, the process speed control adjusted to υ2 can also be determined, controlling the infusion rate to be adjusted in a way that provides a higher “comfort” level, so as to enable the subject to better tolerate and improve tolerance, thereby improving tolerance and infusion “comfort”. For example, if the subject is in good condition but the current feeding volume falls short of expectations (ΔV is negative) and the current infusion rate is lower than the preset target infusion rate (Δυ is negative), the infusion rate can be adjusted slowly towards the target rate υ2 according to the degree of difference and parameters such as subject information and nutrient type
In addition, for adjustment of other nutrient infusion parameters such as the type of nutrient solution, the infusion mode, and the infusion amount, the adjustment method is similar to the adjustment method of the infusion rate, and the current vital sign status parameter and infusion parameters of the subject should be considered comprehensively, and the current infusion parameters should be adjusted to provide a more suitable nutrient intake for the subject, and to ensure effective absorption and utilization of the nutrients.
In one possible example, after the step of adjusting the first nutrient infusion parameter, in order to facilitate the healthcare personnel to view the adjustment record, conduct an infusion review, and more accurately understand the specifics of the infusion process, the nutrient infusion control method of the invention may further include the following step.
Details of the parameter adjustment during the nutrient infusion process are records. The details of the parameter adjustment include a parameter adjustment time and/or the values before and after the parameter adjustment.
As an example, by recording the parameter adjustment time and the values before and after the parameter adjustment during the nutrient infusion process, the user can be helped to more accurately understand the nutrient intake status of the subject, so as to subsequently propose a more suitable nutrient infusion program. For example, in the interface 80 for adjusting the nutrient infusion parameters shown in
The nutrient infusion control method provided by an embodiment of the invention includes: acquiring at least one of nutrient infusion demand information, subject information, and vital sign status parameter of a current subject; determining a first nutrient infusion parameter according to at least one of the nutrient infusion demand information, the subject information, and the vital sign status parameter; performing a nutrient infusion according to the first nutrient infusion parameter; d acquiring a vital sign status parameter and an infusion parameter of the current subject during the nutrient infusion process; and adjusting the first nutrient infusion parameter according to a preset parameter adjustment strategy when it is determined that at least one of the vital sign status parameter and the infusion parameter satisfies a preset parameter adjustment condition. The invention not only quickly and automatically determines the first nutrient infusion parameter directly according to at least one of: the nutrient infusion demand information, the subject information, and the vital sign status parameter, so that the determination of the nutrient infusion parameter no longer depends solely on the nutritionist, and its data accuracy is also higher, so as to improve the accuracy of the control of the nutrient infusion. Also, during the infusion process, the infusion parameters are adjusted in a timely manner according to the actual feeding situation, so as to make it more suitable for the subject, provide a better nutrient infusion for the subject, and ensure the effective absorption and utilization of nutrition.
