[0037] Embodiments of the present invention provide a method, device, equipment, and medium for reducing infusion errors of an infusion pump.

It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0039] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 -Attached Figure 3 In one embodiment of the present invention, a method for reducing an infusion error of an infusion pump includes:

[0040] 101. Construct at least one test model and determine factors in the test model that affect infusion accuracy, wherein the factors have a changing process in the test model;

[0041] In a disclosed embodiment, the test model is used to provide an important parameter value as a calculation result in actual application, and the test model corresponds to a factor that affects the infusion accuracy, that is, there is only one influencing factor in a test model, and the output parameter value is also obtained corresponding to the influencing factor. If different environmental conditions are to be pursued, multiple test models need to be constructed, and the influencing factors in these test models also need to be different. These factors include but are not limited to temperature, humidity, atmospheric pressure, liquid concentration and viscosity of the infusion, hardness, length, diameter and material elasticity of the infusion pipeline, etc., and the change process of the factor is specifically explained as follows: if the factor is temperature, and the change process it has is the change in temperature, it can be the lowest range of more than two hundred degrees to a high temperature of thousands of degrees, as the change process of the factor in the test model.

[0042] 102. Divide the change process according to a preset division standard to obtain multiple change intervals;

[0043] In this embodiment, in order to facilitate the test model to manage the change process of the factors and subsequent regulation, it is necessary to refine this change process into multiple change intervals. Each change interval represents the test status in the current test model, and the test model also has a built-in record table for recording the status information and quantity of these change intervals.

[0044] 103. Calculate the change information in each of the change intervals based on a preset test algorithm in the test model;

[0045] Furthermore, step 103 may further specifically execute:

[0046] 1031. Determine the accuracy calibration value of each of the change intervals.

[0047] In this embodiment, the test algorithm is specifically a precision calibration test method for an infusion pump, which also includes monitoring of the infusion rate. The infusion rate here is a preset rate used in the test model, which belongs to the theoretical infusion rate. These two are existing test methods and will not be described in detail here. Through this test algorithm, the precision calibration value and the corresponding theoretical infusion rate corresponding to each change interval can be directly obtained. The precision calibration value and the theoretical infusion rate corresponding to each change interval will be recorded in a record table, and corresponding to the change interval, a comparison table of change interval-precision calibration value-theoretical infusion rate is obtained;

[0048] In Example 1 of a disclosed embodiment:

[0049] The factor that affects the infusion accuracy can be the theoretical infusion rate. The theoretical infusion rate is subdivided into multiple different speed intervals, and these speed intervals are tested through a test algorithm to obtain the accuracy calibration value under the speed interval, and a speed interval-accuracy calibration value comparison table is established. Subsequently, when detecting the current actual infusion rate, the corresponding accuracy calibration value can be directly obtained from the speed interval-accuracy calibration value comparison table. In actual use, the infusion pump is connected to the infusion device. Since the speed of the infusion rate will have different effects on the degree of squeezing of the infusion device, it will cause the elasticity of the pipeline to decay and affect the infusion accuracy. Therefore, the corresponding theoretical infusion rate can also be achieved by directly obtaining the corresponding accuracy calibration value. In fact, it is achieved by adjusting the motor speed of the infusion pump to reduce the impact on the infusion accuracy.

[0050] Alternatively, the factor affecting the infusion accuracy may be temperature. The temperature is subdivided into multiple different temperature intervals, and the accuracy calibration value in each temperature interval is obtained through a test algorithm. A temperature interval-accuracy calibration value comparison table is established. According to the current temperature conditions, the temperature interval is determined, and the corresponding accuracy calibration value is directly obtained through the temperature interval-accuracy calibration value comparison table. Therefore, the motor speed of the infusion pump can be adjusted through the accuracy calibration value, thereby reducing the impact on the infusion accuracy.

[0051] Alternatively, the factor affecting the infusion accuracy can also be the infusion time. The infusion time is subdivided into multiple different time intervals, and the test algorithm is used to obtain the accuracy calibration value in each time interval, and a time interval-accuracy calibration value comparison table is established. The time interval in which the device is located changes dynamically. The longer the infusion time, the more dynamic changes it will have. Therefore, in order to ensure that the accuracy calibration value in each time interval is called, the time axis of the infusion time can be lengthened in the test model to obtain more time intervals and corresponding accuracy calibration values. The above factors also apply when the theoretical infusion rate or temperature occurs. Whenever the time interval in which the infusion is located undergoes a transition change, the corresponding accuracy calibration value can be directly called from the time interval-accuracy calibration value comparison table to adjust the motor speed of the infusion pump, thereby reducing the impact on the infusion accuracy.

[0052] 1032. Compare the accuracy calibration values ​​in each of the change intervals to obtain calibration value differences between the multiple change intervals;

[0053] 1033. Obtain compensation information using the calibration value difference through the test algorithm.

[0054] In steps 1031-1033, while comparing the precision calibration values ​​corresponding to these variation intervals, the theoretical infusion rates are also compared. The corresponding difference values, i.e., compensation information, can be obtained through comparison. Therefore, the compensation information is actually the compensation for the infusion rate, more specifically, the compensation for the motor speed of the infusion pump. Therefore, a comparison table of variation interval-calibration value difference-compensation information can be directly established. Since the precision calibration values ​​corresponding to the variation intervals in infusion pumps of different types or manufacturers are different, in the actual use of infusion pumps of different types or manufacturers, there will be multiple comparison tables of variation interval-precision calibration values, which will forcibly overwrite the comparison table of variation interval and precision calibration value tested in advance. Therefore, the comparison table of variation interval-calibration value difference-compensation information is used to calculate the precise calibration value under the variation interval we originally tested, and perform corresponding motor speed compensation and regulation.

[0055] The above-mentioned calibration value difference is used instead of directly obtaining the theoretical infusion rate through the preset change interval-precision calibration value comparison table. This method is applied when the current device has not been calibrated or the precision calibration value after calibration has a large error. The above-mentioned calibration value difference calculation scheme can be used. If the device itself has been calibrated and the calibration accuracy is very high and the error is very small, the above-mentioned calibration value difference calculation scheme can be omitted. Instead, the change interval-precision calibration value comparison table that has been directly confirmed in step 1031 can be used to obtain the corresponding theoretical infusion rate.

[0056] In Example 2 of a disclosed embodiment:

[0057] The factor that affects the infusion accuracy is temperature. Temperature represents the state of the actual environment, such as indoor and outdoor, seasonal changes, etc. For example, the temperature range is selected between 0-30 degrees. When dividing, 10 degrees can be used as an interval. However, in order to pursue better accuracy requirements, smaller interval domains can be used, such as 0-2, 2-4, 4-6.........28-30. These intervals are combined into interval groups, and the accuracy calibration value that minimizes the error in each interval is obtained through the test algorithm. The above steps 1032-1033 are executed to obtain the corresponding temperature interval-calibration value difference-compensation information comparison table.

[0058] The factor that affects the infusion accuracy is the infusion time. Since infusion is a continuous process, the longer the infusion pump is squeezed during this continuous infusion process, the greater the degree of its elastic attenuation, and the corresponding total infusion error also becomes larger. Therefore, the infusion time is divided into multiple time intervals, and the accuracy calibration values ​​corresponding to these time intervals are obtained through the test algorithm. In order to ensure that errors are reduced during long-term infusion, the difference between the accuracy calibration value and the pre-configured calibration value is calculated to obtain the optimal infusion pump motor speed to adjust the final infusion volume without deviation.

[0059] 104. Obtaining an actual infusion volume, and comparing the actual infusion volume with the change information to obtain an infusion error;

[0060] The specific implementation of obtaining the actual infusion volume is as follows: the actual infusion volume can be calculated through the infusion situation of the actual infusion rate (the actual speed of the infusion pump) within a specified time. However, there may be certain interference in the actual infusion rate, resulting in a deviation between the final infusion volume calculated and the actual infusion volume. Therefore, in this embodiment, external equipment such as a balance scale and other detection devices are used to detect and obtain the actual infusion volume. Finally, the actual infusion volume is compared with the change information to obtain the infusion error. The infusion error here refers to the error value of the infusion volume.

[0061] 105. Utilize the change information and a preset correction algorithm to correct the actual infusion volume.

[0062] In this embodiment, it should be noted that no matter what factors affect the infusion accuracy, the numerical detection or collection of the factors is obtained directly or indirectly by sensors and other equipment. For example, the motor speed of the infusion pump is monitored by the infusion pump, the temperature is collected by the temperature sensor, and the infusion time is measured by the timer.

[0063] In Example 3 of a disclosed embodiment:

[0064] There are two test models used in the method for reducing infusion errors of the infusion pump. The factors in the two test models include temperature and infusion time, temperature and theoretical infusion rate, infusion time and theoretical infusion rate, and a combination of other two test models with different factors.

[0065] Take temperature and theoretical infusion rate as an example:

[0066] When the device is turned on, according to the speed range in which the current theoretical infusion rate is located, directly obtain the accuracy calibration value of the speed range from the speed range-accuracy calibration value comparison table, record the accuracy calibration value A, and use this accuracy calibration value A as the current infusion accuracy calibration value;

[0067] The external temperature information is collected by the temperature sensor. According to the different types or brands of infusion pumps, the temperature range and precision calibration value of the external temperature information are obtained. The precision calibration value of the temperature range is compared with the precision calibration value of the temperature range of the external temperature in which the precision calibration value A was last calibrated to obtain the calibration value difference a. The precision calibration value A and the calibration value difference a are calculated to obtain the precision calibration value B. Finally, the precision calibration value B is used as the current infusion precision calibration value for infusion;

[0068] It should be noted that when the accuracy calibration value is changed by calculating the difference with the calibration value, it is specifically implemented in the increase or decrease of the motor speed of the infusion pump. For example, when the current infusion accuracy calibration value changes in a certain range of changes, the current infusion accuracy standard value will be changed or converted to a new accuracy calibration value by calculating the difference with the calibration value. This conversion process directly changes the current motor speed of the infusion pump, thereby changing the current actual infusion volume.

[0069] In Example 4 of a disclosed embodiment:

[0070] There are three test models used in the method for reducing the infusion error of the infusion pump. The factors in the three test models include theoretical infusion rate, temperature and infusion time, and a combination of test models of three other different factors.

[0071] Take the theoretical infusion rate, temperature and infusion duration as an example:

[0072] Since the theoretical infusion rate and temperature can be obtained immediately after the device is turned on, the infusion time needs to be processed using the length of time. The execution method of the mutual influence of the theoretical infusion rate and temperature is the same as that of the above example three, so it will not be repeated. Therefore, the current infusion accuracy calibration value is the accuracy calibration value B that has been processed. As the infusion work progresses, time continues to accumulate. Therefore, each time a time interval passes, the accuracy calibration value B needs to be calculated with the calibration value obtained in the current time interval. Finally, the accuracy calibration value C is obtained as the current time. The infusion accuracy calibration value within the time interval. It should be noted that the time interval-calibration value difference comparison table is the same as the temperature interval-calibration value difference comparison table. Both are obtained in advance in the test model. Therefore, when the infusion time is continuously accumulated, there will be a corresponding calibration value difference in each time interval it passes. Therefore, it is necessary to control the change in the current infusion pump motor speed by continuously correcting the current infusion accuracy calibration value to ensure that the final total infusion amount will not have too large an error, and reduce the impact of fatigue and elastic attenuation of the infusion pipeline in the infusion pump due to long-term infusion on the infusion accuracy.

[0073] In Example 5 of a disclosed embodiment:

[0074] The test models used in the method for reducing the infusion error of the infusion pump include three or more test models, and the factors in the three or more test models include a combination of test models of three or more different factors.

[0075] Furthermore, step 105 may further specifically execute:

[0076] 1051. Obtain actual infusion rate;

[0077] 1052. Compare the actual infusion volume obtained according to the actual infusion rate within the preset time with the theoretical infusion volume to obtain an infusion error;

[0078] 1053. According to the infusion error, compensate the actual infusion rate with the compensation information to obtain a new actual infusion rate.

[0079] The change information includes the theoretical infusion volume, which is calculated based on the theoretical infusion rate and the specified time. A cup and a cover to prevent liquid evaporation are placed on the balance scale. The output end of the infusion device is connected to the cup, and the infusion is guided by the infusion pump. The final amount of liquid obtained by the cup is the actual infusion volume. By comparing the actual infusion volume with the theoretical infusion volume, the infusion error is obtained, where the error value has an acceptable range. If the error value exceeds the acceptable range, the infusion accuracy calibration value can be manually readjusted to change the actual infusion rate, that is, the actual infusion rate is compensated by compensation information. More specifically, the motor speed of the infusion pump is corrected to ensure that the actual infusion volume obtained is close to the theoretical infusion volume.

[0080] In an embodiment of the present invention, by constructing at least one test model in which there are factors corresponding to the factors affecting the infusion accuracy, the change process in the factors is divided according to the division criteria to obtain multiple change intervals, and the change information in the multiple change intervals is calculated by the test algorithm. Using these change information, the actual infusion volume is corrected through the correction algorithm, so as to effectively reduce the errors in the infusion process in different scenarios. From the above-mentioned multiple embodiments, the accuracy of the infusion precision can be controlled accordingly under the conditions of temperature differences, different specifications of infusion devices and / or different infusion times, and the influence of fatigue of the infusion pipeline caused by these factors on the overall infusion rate is reduced.
