In practice, infusion is primarily performed using traditional intravenous drips. To ensure accurate drug delivery and achieve better therapeutic outcomes for patients, the drip rate is often slow. However, low drip rates still result in significant drug delivery deviations, and a method for regulating low drip rates is lacking.

[0012] Monitor the actual drip rate during the infusion process;

[0013] In the case where the actual dripping rate does not match the preset dripping rate, an abnormal dripping test is performed, and if the test result is abnormal, an alarm message is output.

[0014] In one embodiment, the step of monitoring the actual drip rate during the dripping process includes:

[0015] Before the timing result of the timing reaches the single drop duration, the number of changed levels in the drip rate sensor is determined, and the actual drip rate is determined according to the number of changed levels.

[0016] In one embodiment, the step of performing abnormal drip testing includes:

[0017] The number of test periods in the cumulative dripping process, wherein the test period is the time period between the start timing operation and the next adjacent reset timing result operation;

[0018] After the number of the inspection periods reaches a first preset number, determining the number of abnormal periods in each of the inspection periods, wherein the abnormal period is a time period when the actual dripping rate does not match the preset dripping rate;

[0019] In a case where the number of the abnormal time periods is greater than a second preset number, the inspection result is determined to be abnormal.

[0021] In a case where the number of the abnormal time periods is equal to or smaller than a second preset number, the inspection result is determined to be normal.

[0022] In one embodiment, the method further comprises:

[0030] In addition, to achieve the above-mentioned purpose, the present application also provides a computer program product, which includes a computer program. When the computer program is executed by a processor, it implements the steps of the low drip rate drip optimization method as described above.

[0031] The present application proposes a low dripping rate dripping optimization method, which first receives a preset dripping rate of the dripping process, increases the speed of the dripping motor and starts timing, so that the droplets can drip quickly and complete the dripping of the droplets in the time unit of the set dripping rate; by reducing the speed of the dripping motor when it is detected that there are droplets dripping into the drip bucket during the dripping process, to ensure that only one drop of liquid is dripped in the time unit of the set dripping rate; by resetting the timing result after the timing result reaches the single drop duration corresponding to the preset dripping rate, and returning to the steps of increasing the speed of the dripping motor and starting timing, the dripping rate of the dripping is regulated to always follow the set dripping rate.

[0032] In summary, the present application adjusts the dripping speed of the droplets by continuously controlling the speed of the motor during the time period of setting the dripping speed, thereby overcoming the problem of large drug delivery deviation under low dripping speed conditions and achieving the effect of effectively regulating the dripping process at low dripping speed.

[0041] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0042] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0043] The main solutions of the embodiments of this application are:

[0044] In existing technologies, infusions are primarily administered via traditional intravenous drips. To ensure accurate drug delivery and achieve better therapeutic outcomes for patients, the drip rate is often slow. However, low drip rates can still result in significant drug delivery deviations, and there is a lack of a method for regulating low drip rates. Therefore, effectively regulating the low-rate drip process is an urgent problem that needs to be addressed.

[0045] The present application provides a solution, which adjusts the dripping speed of the droplets by continuously controlling the speed of the motor during the time period of setting the dripping speed, thereby overcoming the problem of large drug delivery deviation under low dripping speed conditions and achieving the effect of effectively regulating the dripping process at low dripping speed.

[0046] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or a terminal device capable of implementing the above functions. The following uses a terminal device as an example to illustrate this embodiment and the following embodiments.

[0047] Based on this, the present invention provides a method for optimizing low dripping speed. Figure 1 , Figure 1 This is a flow chart of the first embodiment of the low drip rate drip optimization method of the present application.

[0048] In this embodiment, the low drip rate drip optimization method includes steps S10 to S30:

[0049] Step S10, receiving a preset dripping rate of the dripping process, increasing the rotation speed of the dripping motor and starting timing, wherein the dripping rate of the dripping process is positively correlated with the rotation speed of the dripping motor;

[0050] It should be noted that the drip motor is a motor used for precision dripping and micro-delivery. It can accurately control the flow rate and dripping speed of the liquid by controlling the rotation speed of the infusion pump disc according to the preset drip rate setting, ensuring that the liquid is delivered at a stable speed and amount; increasing the rotation speed of the drip motor is to increase the rotation speed of the drip motor from the preset normal speed to the preset acceleration speed. At the preset acceleration speed, the rotation speed of the drip motor can make the droplets drip quickly.

[0051] In addition, it should be noted that the preset dripping rate can be set by the user during the treatment process, or can be pre-stored in the terminal device. This embodiment does not specifically limit the method for obtaining the preset dripping rate.

[0052] It can be understood that since the flow rate of the liquid itself is very slow, performing step S10 can avoid the problem of the liquid being unable to drip out due to the liquid flow rate being too slow. The flow rate of the liquid is accelerated by increasing the rotation speed of the drip motor, so that the droplets can drip quickly, so as to complete the dripping of the droplets within the time unit of the set dripping rate.

[0053] For example, the terminal device receives a drip rate of two drops per minute for the drip process, that is, the preset drip rate is two drops per minute. Then, the drip rate in the drip process is accelerated by increasing the speed of the drip motor to the preset acceleration speed, and a thirty-second countdown is started.

[0054] Step S20, when it is detected that liquid drops fall into the dripping bucket during the dripping process, reducing the rotation speed of the dripping motor;

[0055] It should be noted that reducing the speed of the drip motor is to reduce the speed of the drip motor to a preset normal speed. At the preset normal speed, the speed of the drip motor can maintain the dripping speed at a dripping speed that only ensures that the blood does not flow back during the dripping process, that is, to ensure the normal flow direction of the liquid during the dripping process.

[0056] It can be understood that since the flow rate of the liquid after acceleration is faster, while the flow rate of the liquid itself is very slow, performing step S20 can avoid the problem of uncontrolled dripping rate of the liquid after acceleration, by reducing the speed of the drip motor to the preset normal speed, thereby ensuring that only one drop of liquid drips into the drip bucket in the time unit of the set dripping rate.

[0057] Step S30: after the timing result reaches the single-drop duration corresponding to the preset dripping speed, the timing result is reset, and the process returns to the step of increasing the rotation speed of the dripping motor and starting timing.

[0058] It should be noted that the single drop duration is obtained based on the preset dripping rate, which is the length of time it takes for a single drop of liquid to fall.

[0059] For example, when the preset dripping rate is one drop per minute, the time length for a single drop of liquid to drip is set to one minute, that is, the single drop duration is one minute, and the timing starts from the moment the motor is started. When the one-minute timing is over, the one-minute timing result is reset, and the speed of the drip motor is continued to be increased, and the timing is started at the same time.

[0060] In a feasible implementation, the method may further include step S01:

[0061] Step S01 : monitoring the dripping condition of the liquid droplets in the drip bucket by using a drip rate sensor. When the drip rate sensor generates a level change, determining that the dripping condition is that the liquid droplets are dripping into the drip bucket.

[0062] It should be noted that the drip rate sensor can monitor the dripping condition of liquid droplets through infrared detection or other photoelectric detection methods, such as visible light detection, laser detection, etc. This embodiment does not specifically limit the method of monitoring the dripping condition of liquid droplets by the drip rate sensor.

[0063] Exemplarily, the drip rate sensor includes at least a light source emitter and a light source detector. The drip rate sensor emits light through the light source emitter (usually a light emitting diode). When the droplet passes through the path between the light source and the photoelectric semiconductor, the droplet partially or completely blocks the light. The light source detector can convert the light signal into an electrical signal. When the photoelectric irradiation is applied to the photoelectric semiconductor of the light source detector, the semiconductor generates an electric current. When the droplet passes through the light beam, it blocks the light, causing the light intensity received by the photoelectric semiconductor to decrease, thereby reducing the current generated, and the change in current is converted into a change in the level signal. When no droplet passes, the photoelectric semiconductor keeps outputting a level signal, and when the droplet passes, the photoelectric semiconductor outputs another level signal, wherein the level signal includes a high level signal and a low level signal. Therefore, the level change generated by the drip rate sensor determines that there is a situation where the droplet falls into the drip bucket at this time.

[0064] Exemplarily, the drip rate sensor includes at least an infrared emitter and an infrared detector. The drip rate sensor emits a beam of infrared light through the infrared emitter. When a droplet passes through the infrared beam, the droplet will partially or completely block the transmission of the beam. At this time, the infrared detector corresponding to the infrared emitter can detect changes in the passing beam, such as a decrease in the intensity of the infrared light received by the detector. The change in light intensity caused by the droplet passing through the infrared beam is converted by the detector into a change in the level signal. When no droplet is dripping, the detector maintains the output of a low-level signal, and when a droplet is detected, the detector outputs a high-level signal. Therefore, the level change generated by the drip rate sensor determines that there is a droplet dripping into the drip bucket at this time.

[0065] In this embodiment, the dripping condition of the liquid drop is determined by the change of the level signal in the drip rate sensor, which solves the problem of how to know whether the liquid drop has dripped into the drip bucket.

[0066] This embodiment provides a low drip rate infusion optimization method. By continuously controlling the speed of the motor during the time period of the set drip rate, the dripping speed of the droplets is adjusted, thereby overcoming the problem of large drug delivery deviation under low drip rates and achieving the effect of effectively regulating the low drip rate infusion process.

[0067] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 2 , Figure 2 This is a flow chart of the second embodiment of the low dripping speed optimization method of the present application. The low dripping speed optimization method, after the steps of increasing the speed of the dripping motor and starting the timing, further includes steps S11 to S12:

[0068] Step S11, monitoring the actual dripping rate during the dripping process;

[0069] It should be noted that the actual dripping rate is a value calculated based on the timing duration and the number of droplets dripped within the timing duration, which can be used to represent the speed of the droplet dripping.

[0070] It is understandable that since various abnormal dripping situations may occur during the dripping process, obtaining the actual dripping rate of the dripping liquid can be used to determine whether the abnormal situation requires human intervention to deal with it. Therefore, performing step S11 can avoid the user from not knowing the abnormal situation that occurs during the dripping process, thereby enabling the user to know the abnormal situation that occurs during the dripping process.

[0071] In a feasible implementation, the step of monitoring the actual dripping rate during the dripping process in step S11 may include step S111:

[0072] Step S111 : before the timing result reaches the single drop duration, determining the number of changed levels in the drip rate sensor, and determining the actual drip rate according to the number of changed levels.

[0073] For example, when the preset drip rate is one drop / minute, the drip rate sensor starts timing after receiving the preset drip rate and starting the drip motor. Before the single drop duration reaches one minute, two high-level signals are generated, and it is determined that the actual drip rate of the drip process during this period is two drops / minute.

[0074] Step S12: When the actual dripping rate does not match the preset dripping rate, an abnormal dripping test is performed, and when the test result is abnormal, an alarm message is output.

[0075] It should be noted that the warning information is used to remind the user that there is an abnormality in the infusion process and that immediate human intervention is required.

[0076] For example, when the actual dripping rate is two drops / minute and the preset dripping rate is one drop / minute, it is considered that the actual dripping rate and the preset dripping rate do not match each other, and an abnormal dripping inspection process is performed. After the inspection process, if the inspection result is abnormal, an alarm message is output to prompt the user.

[0077] In a feasible embodiment, the step of performing abnormal drip testing in step S12 may include steps S121 to S123:

[0078] Step S121, accumulating the number of test periods in the dripping process, wherein the test period is the time period between the start of the timing operation and the next adjacent reset timing result operation;

[0079] It should be noted that the inspection period is a period defined by a specific type of abnormal condition that occurs during the infusion process, wherein the start timing operation is an operation for executing the start timing, and the reset timing result operation is an operation for executing the reset timing result.

[0080] In addition, it should be noted that the number of test periods in the cumulative dripping process is accumulated from the time when the actual dripping rate does not match the preset dripping rate and the time between the start of timing and the adjacent reset timing result, as the first test period.

[0081] Step 122, after the number of the inspection periods reaches a first preset number, determining the number of abnormal periods in each of the inspection periods, wherein the abnormal period is a time period when the actual dripping rate does not match the preset dripping rate;

[0082] It should be noted that the abnormal period refers to a period during the inspection period when the actual dripping rate does not conform to the preset dripping rate; the first preset number is a threshold value set to limit the number of defined inspection periods.

[0083] It can be understood that since the degree of abnormal conditions existing during the infusion process is different, performing step S122 can avoid the user being unable to know the degree of abnormality occurring during the infusion process, and can achieve the effect that the user can know the type of abnormal condition occurring during the infusion process.

[0084] Exemplarily, when the preset dripping rate is one drop / minute and the monitored actual dripping rate does not match the preset dripping rate, the timing period in which the actual dripping rate is monitored to not match the preset dripping rate, that is, the minute in which the actual dripping rate does not match the preset dripping rate, is taken as the first inspection period, and subsequent steps are continued to be performed normally. When the first preset number is five, after the number of defined inspection periods is continuously accumulated to reach the set threshold of five, the inspection period in which the actual dripping rate does not match the preset dripping rate in each inspection period is taken as an abnormal period, and the number of the abnormal periods is determined.

[0085] Step S123: When the number of abnormal time periods is greater than a second preset number, determining that the inspection result is abnormal.

[0086] It should be noted that the second preset number is a value set for determining the type of the test result.

[0087] Exemplarily, when there are three abnormal periods in the inspection period and the second preset number is one, it is considered that the number of abnormal periods is greater than the second preset number, and the inspection result is determined to be abnormal.

[0088] In a feasible implementation manner, after the step of determining the number of abnormal time periods in each inspection time period in step S122, the method may further include step S124:

[0089] Step S124 : When the number of abnormal time periods is equal to or less than a second preset number, determining that the inspection result is normal.

[0090] It is understandable that, since occasional abnormal conditions may occur during the dripping process, but the impact on the dripping process is negligible, performing step S124 can increase the fault tolerance rate of abnormal conditions occurring during the dripping process, so as to achieve more accurate control of the dripping process at a low dripping rate.

[0091] For example, when there is an abnormal period and the second preset number is one, it is considered that the number of abnormal periods is equal to the second preset number. It may be an accidental error condition, such as external collision, droplets remaining on the tube wall sliding, etc., which causes additional dripping of droplets to be monitored. At this time, the inspection result is determined to be normal.

[0092] In this embodiment, the accuracy of the control during the infusion process is improved by detecting and identifying normal errors occurring during the infusion abnormality.

[0093] In this embodiment, by checking the abnormal type of abnormal dripping, different response measures are taken for different abnormal types, thereby reducing the deviation of low drip rate drip control, thereby improving the control accuracy during the low drip rate dripping process.

[0094] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the first embodiment and / or the second embodiment can be referred to the above introduction and will not be described in detail later. Figure 3 , Figure 3 This is a flow chart of the third embodiment of the low drip rate drip optimization method of the present application. The low drip rate drip optimization method further includes step S40:

[0095] Step S40: After the single duration of increasing the rotation speed of the drip motor reaches a preset duration, the drip motor is stopped, the rotation speed of the drip motor is prohibited from being increased, and a drip completion prompt message is output.

[0096] It should be noted that the single time duration is the length of time the drip motor starts timing after increasing the speed; the preset time duration is the time threshold set to limit the motor working time; the drip completion prompt message is used to prompt the user that the dripping process has completed all liquid dripping and requires human intervention.

[0097] It is understandable that after the last drop of liquid is dripped, the motor will increase the speed again. At this time, the drop cannot be dripped because there is no drop to accelerate. Therefore, step S40 is performed to avoid the waste of resources caused by long-term operation of the motor and to achieve precise control of the dripping process.

[0098] For example, when the time for increasing the speed of the drip motor reaches a preset one-minute threshold, that is, when the single duration reaches the preset duration of one minute, the acceleration of the drip motor is stopped, and the drip motor is prohibited from increasing the speed again, and a prompt message is output to remind the user that the drip process has been completed and human intervention is required.

[0099] In this embodiment, the motor is stopped after increasing its speed for a long time and the speed of the motor is prohibited from increasing, so that the motor startup is terminated when the dripping process is completed, thereby further improving the control accuracy during the dripping process at a low dripping rate.

[0100] For example, in order to help understand the implementation process of the low drip rate drip optimization method obtained by combining the above-mentioned embodiment 1 and embodiment 2, please refer to Figure 4 , Figure 4 A brief flow chart of a low drip rate infusion optimization method is provided, specifically:

[0101] First, the speed of the drip motor is increased to accelerate the drip process. Within the preset time, it is detected whether there are any droplets dripping. If no droplets are dripping, the drip process is considered to be completed, and the motor is stopped. If there are droplets dripping, the actual drip rate of the drip process is monitored. When the actual drip rate matches the preset drip rate, the motor speed is reduced, and then the motor speed is increased again to accelerate the drip rate, and the whole process is repeated. When the actual drip rate does not match the preset drip rate, an abnormal drip test is performed. After passing the test, if the test result is normal, the motor speed is reduced, and then the motor speed is increased again to accelerate the drip rate, and the whole process is repeated. If the test result is abnormal, an alarm message is output, the motor speed is reduced again, and then the motor speed is increased again to accelerate the drip rate, and the whole process is repeated.

[0102] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the low drip rate infusion optimization method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0104] The acceleration module 10 is used to receive a preset dripping rate during the dripping process, increase the rotation speed of the dripping motor and start timing, wherein the dripping rate during the dripping process is positively correlated with the rotation speed of the dripping motor;

[0105] The speed reduction module 20 is used to reduce the rotation speed of the dripping motor when detecting that liquid drops fall into the dripping bucket during the dripping process;

[0106] The re-acceleration module 30 is used to reset the timing result after the timing result reaches the single drop duration corresponding to the preset dripping speed, and return to the step of increasing the speed of the dripping motor and starting timing.

[0107] Optionally, the device further comprises:

[0108] The dripping condition of the liquid droplets in the drip bucket is monitored by a dripping rate sensor. When the dripping rate sensor generates a level change, it is determined that the dripping condition is that the liquid droplets drip into the drip bucket.
