[0001] This application relates to the field of medical technology, and in particular to an infusion control method, device and storage medium. Background Technology

[0002] With the development of medical technology, infusion devices with high accuracy and safety have been widely used. They can use mechanical driving force to accurately control the number of infusion drops and the infusion flow rate, ensuring that the drugs can enter the patient's body accurately and safely.

[0003] However, the amount of medication that an infusion device can deliver at one time is always limited. In the treatment of critically ill patients, there is usually a need for continuous and long-term infusion, which inevitably leads to situations where medication and pump changes are required. During the process of changing medication and pumps, the flow rate of the medication will inevitably fluctuate. When the flow rate fluctuates significantly, it will affect the patient's vital signs and, in severe cases, even endanger the patient's life.

[0053] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0054] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0055] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises 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.

[0056] Critically ill patients require vasoactive drugs to improve blood pressure, cardiac output, and microcirculation due to hemodynamic instability during treatment. Vasoactive drugs work by regulating vasomotor activity, altering vascular function, and improving microcirculatory perfusion to combat shock. Common examples include dopamine, sodium nitrophenyl, and adrenaline. Some intensive care patients often require continuous use of vasoactive drugs. Fluctuations in flow rate inevitably occur during routine dressing and pump changes, which can affect vital signs and even endanger life. Minimizing flow rate changes caused by dressing and pump changes to ensure stable flow rates during continuous vasoactive drug administration and thus improve infusion safety is a current challenge.

[0057] To address the aforementioned problems, this application provides an infusion control method. This method pre-calculates the rise time required for the second infusion device to reach the target infusion rate from the start of infusion. A pre-start prompt message is sent to the second infusion device before the rise time from the end of the first infusion device's infusion. This ensures that the second infusion device reaches the target infusion rate before the first infusion device finishes infusion, and thus continues infusion at the target rate after the first infusion device finishes. In this way, the infusion flow rate remains stable even when changing pumps or medications, reducing safety hazards caused by flow rate changes during medication or pump replacements and improving infusion safety.

[0058] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0059] Figure 1 This is a flowchart illustrating an infusion control method provided in an embodiment of this application. The executing entity in this embodiment can be an infusion control device, which can be located on various medical electronic devices within the infusion system. These medical electronic devices can be medical devices such as a first infusion device, an infusion central station, an infusion workstation, or an infusion monitoring system, or they can be mobile terminals or computers used in conjunction with medical devices. This application does not impose any limitations.

[0060] In addition, the infusion system also includes a second infusion device. The first and second infusion devices involved in this application can be infusion pumps, syringe pumps, etc., used to control infusion process parameters such as drug flow rate. The first and second infusion devices are connected via wired and / or wireless means to exchange information, thereby achieving steady-state infusion based on the method of this application.

[0061] For example, the first and second infusion devices can be connected via wired connections such as network cables, coaxial cables, or optical fibers for data exchange. Alternatively, a communication link can be established between the first and second infusion devices using wireless technologies such as WiFi, 4G, 5G, Bluetooth, or Zigbee, providing a foundation for data communication between them. In practical applications, one or more of these technologies can be combined to achieve a better steady-state infusion. In one embodiment, the first and second infusion devices can also be plugged into an infusion workstation for a wired connection.

[0062] In this embodiment, when n (n≥2) infusion devices are involved in continuous steady-state infusion, the infusion control device can also be located on the first n-1 infusion devices, thereby realizing continuous steady-state infusion of multiple infusion devices.

[0063] For example, this application describes an embodiment where the execution subject is an infusion control device. Figure 1 As shown, the infusion control method provided in this embodiment includes:

[0064] S101. Obtain the rise time of the second infusion device; wherein, the rise time is the time required for the second infusion device to reach the target infusion rate from the start of infusion.

[0065] For example, steady-state infusion involves multiple infusion devices for continuous infusion, including at least a first infusion device and a second infusion device. The first infusion device generally refers to the infusion device currently infusion or about to begin infusion, and the second infusion device generally refers to the next infusion device following the first. The purpose of steady-state infusion is to control the flow rate of the medication throughout the infusion process, preventing excessive fluctuations in flow rate that could affect the patient's vital signs or even endanger their life. In this application, the infusion control device first needs to obtain the rise time of the second infusion device. The rise time refers to the time required for the second infusion device to reach the target infusion rate from the start of infusion. It should be noted that "starting infusion" here does not mean actually beginning infusion on the patient, but only pre-starting the infusion operation so that the infusion device reaches the target infusion rate before infusion is administered to the patient. The rise time is related to one or more of the following: the driving parameters of the second infusion device, the specifications of the syringe connected to the second infusion device, and the target infusion rate.

[0066] For example, the driving parameters of the second infusion device are inherent parameters characterizing the infusion device's ability to drive the drug solution. These parameters are related to both the driving distance parameters of the infusion device, such as transmission clearance and pusher clearance, and the driving force parameters, such as driving force, driving power, and device rigidity. Due to machining errors, the driving parameters of each infusion device will vary to some extent, which can be obtained through testing and calibration before leaving the factory. The specifications of the syringe may include parameters such as the syringe's diameter, length, and capacity, or a comprehensive set of parameters determined by these parameters.

[0067] In one example, the rise time can be calculated using the following formula:

[0068]

[0069] In the formula, t0 is the rise time, M can be the driving parameter of the second infusion device in mm, v can be the target infusion rate of the second infusion device in ml / h, A is a parameter determined by the specifications of the syringe in mm / h, which can be obtained by dividing the length of the syringe by its capacity, and k is a calibration coefficient. This coefficient is negatively correlated with the speed; the smaller the speed, the larger K is, generally greater than or equal to 1, and this application does not impose any limitation. Accordingly, the calculated rise time t0 is in hours, and the unit can be converted according to actual needs, for example, to minutes.

[0070] The rise time of the second infusion device can be calculated by any medical device in the infusion system and then shared with other medical devices that need this data; this application does not impose any restrictions. In practical applications, the device that calculates the rise time can obtain the parameters in formula (1) and then substitute them into the formula to calculate the rise time.

[0071] For example, obtaining the parameters described above can be a process of setting parameters for each infusion device performing steady-state infusion before infusion. When setting parameters, the user can directly input parameter values, or pre-set corresponding values ​​for some parameters, which the user can then select and retrieve. For example, inputting / selecting parameters such as drug name, drug concentration, target infusion rate, flow rate, and preset volume; or inputting / selecting information such as the brand, model, and specifications of the infusion device, and then retrieving the corresponding driving parameters for the second infusion device, etc., are all possible scenarios. This application does not impose any limitations.

[0072] In some examples, multiple infusion devices performing steady-state infusion have some or all of the same infusion parameters. To save parameter setting time and improve user experience, the infusion control method of this application may further include:

[0073] The infusion parameter information of the first infusion device is sent to the second infusion device.

[0074] For example, before infusion, multiple infusion devices for steady-state infusion and their infusion parameters need to be set up. These parameters include drug name, drug concentration, target infusion rate, flow rate, and preset volume. If the same drug is used for infusion or the infusion parameters of each device are identical, the infusion parameters of each device can be designed to be synchronized with a single click, allowing the already set parameters to be synchronized to other infusion devices. For instance, if the output parameter information of the first infusion device is the same as that of the second infusion device, then after the infusion parameter information of the first infusion device is set, it can be directly sent to the second infusion device, saving time in setting parameters.

[0075] For example, Figure 2a This is a schematic diagram of a steady-state infusion setting interface provided in an embodiment of this application. Figure 2a As shown, based on the steady-state infusion setting interface 200, steady-state infusion settings can be configured for each infusion device to be infused, and the infusion sequence information of each infusion device can be determined. The interface shown includes steady state 1 and steady state 2, indicating that after the infusion of the device in steady state 1 (this machine) is completed, the infusion device in steady state 2 will continue to infuse.

[0076] For example, Figure 2b This is a schematic diagram of an input parameter setting interface provided in an embodiment of this application. Figure 2bAs shown, based on the infusion parameter setting interface 300, parameters such as the infusion drug 310, target infusion rate 320, preset volume 330, and remaining time 340 of each infusion device can be set. Steady state 2, indicated by label 10, represents the settings of the infusion parameters for the infusion device in steady state 2. The infusion drug shown is norepinephrine, the target infusion rate is 10.0 ml / h, the preset volume is 50.00 ml, and the remaining time is 5 h.

[0077] in, Figure 2a and Figure 2b This is just one example; other parameters may be displayed in the settings interface of a real application, and this application does not impose any restrictions.

[0078] S102. Determine the infusion end time of the first infusion device.

[0079] For example, in order to achieve steady-state infusion, the infusion control device also needs to make the infusion rate of the second infusion device reach the target infusion rate before the infusion of the first infusion device ends. Therefore, it is also necessary to determine the infusion end time of the first infusion device.

[0080] For example, determining the infusion end time of the first infusion device may include:

[0081] Obtain the infusion status of the first infusion device, and determine the infusion end time of the first infusion device based on the infusion status.

[0082] For example, the infusion status of the first infusion device can be monitored, and information such as the actual remaining infusion volume and actual infusion rate of the first infusion device can be obtained based on the specific situation of the infusion status. Then, the infusion end time can be determined based on this information.

[0083] S103. At least before the rise time from the end of the infusion time, output a pre-start prompt message to the second infusion device.

[0084] For example, after determining the rise time of the second infusion device and the infusion end time of the first infusion device, the infusion control device also needs to output a pre-start prompt message to the second infusion device at least before the rise time of the infusion end time. The pre-start prompt message is used to instruct the second infusion device to pre-start, so that the second infusion device reaches the target infusion rate before the first infusion device finishes infusion.

[0085] For example, if the rise time required for the second infusion device to reach the target infusion rate from initiation is determined to be 10 minutes, a pre-start prompt message should be sent to the second infusion device at least 10 minutes before the first infusion device finishes infusion, so that the second infusion device can reach the target infusion rate in advance. Then, after the first infusion device finishes infusion, the second infusion device can directly start infusion at the target infusion rate, avoiding large speed fluctuations that may occur during the connection between infusion devices. This allows for continuous and uninterrupted infusion at a relatively stable desired infusion rate, reducing the probability of significant changes in the patient's vital signs and improving infusion safety.

[0086] For example, if the infusion control device is applied to the first infusion device, when outputting the pre-start prompt information to the second infusion device, the first infusion device can send the information directly to the second infusion device, or the first infusion device can first send the pre-start prompt information to the infusion workstation / infusion central station, and then the infusion workstation / infusion central station can forward it to the second infusion device. If the infusion control device is applied to the infusion workstation / infusion central station, the infusion workstation / infusion central station can also send the pre-start prompt information to the second infusion device after determining the rise time of the second infusion device and the infusion end time of the first infusion device, but before the rise time of the infusion end time of the first infusion device.

[0087] Regardless of the method used to send the pre-start prompt information, this application does not impose any restrictions as long as the second infusion device receives the pre-start prompt information before the first infusion device finishes infusion and reaches the target infusion speed in advance.

[0088] The infusion control method provided in this application includes: acquiring the rise time of a second infusion device; wherein the rise time is the time required for the second infusion device to reach the target infusion rate from the start of infusion; determining the infusion end time of a first infusion device; and outputting a pre-start prompt message to the second infusion device at least before the rise time from the infusion end time. The infusion control method of this application sends a pre-start prompt message to the second infusion device before the rise time from the infusion end time of the first infusion device, instructing the second infusion device to reach the target infusion rate before the first infusion device finishes infusion. This allows the second infusion device to directly start infusion at the target infusion rate after the first infusion device finishes infusion, thereby avoiding large speed fluctuations during the connection of infusion devices. This ensures continuous and uninterrupted infusion at a desired and relatively stable infusion rate during continuous infusion, reducing the probability of significant changes in the patient's vital signs and improving infusion safety.

[0089] In some examples, if the infusion control device is applied to an infusion workstation / infusion central station, and the infusion control is performed by the infusion workstation / infusion central station, the infusion control method of this application may further include, after outputting a pre-start prompt message to the second infusion device:

[0090] When the actual infusion rate of the second infusion device reaches the target infusion rate, a compliance prompt message is issued; if the first infusion device does not receive a compliance prompt message from the second infusion device within a preset time after the infusion ends, a non-compliance alarm is output.

[0091] For example, the infusion workstation / infusion central station can also be used to monitor the infusion status of the first and second infusion devices, and issue a compliance prompt when the actual infusion speed of the second infusion device reaches the target infusion speed, to notify the first infusion device or relevant personnel that the actual infusion speed of the second infusion device has reached the target infusion speed and equipment switching can be performed. Furthermore, it can be further determined whether the first infusion device received the compliance prompt from the second infusion device within a preset time after the infusion ends. If it is determined that the first infusion device received the compliance prompt from the second infusion device within the preset time after the infusion ends, then the normal operation of each device continues, or a clear prompt indicating that the compliance prompt from the second infusion device has been received is issued. If it is determined that the first infusion device did not receive the compliance prompt from the second infusion device within the preset time after the infusion ends, then a non-compliance alarm is output to prompt the user to handle the abnormality as soon as possible.

[0092] This application does not impose any restrictions on the specific value of the preset time. For example, the preset time can be set to a value greater than or equal to 0, depending on actual needs. When the preset time is 0, meaning the first infusion device has just finished infusion, and the target completion notification from the second infusion device has not yet been received by the first device, a failure alarm is issued. This allows more time for the second infusion device to pre-start, enabling it to reach the target infusion rate as close as possible to the start of infusion. More preferably, time is reserved for the user to handle abnormal situations. Setting the preset time to 30 seconds, 1 minute, or another small value greater than 0 allows time for the user to handle abnormal situations without significantly affecting the infusion results.

[0093] In addition, the first infusion device can perform self-monitoring. If it does not receive a compliance prompt from the second infusion device within a preset time after the infusion ends, it will output a non-compliance alarm.

[0094] Figure 3 This is a flowchart illustrating another infusion control method provided in an embodiment of this application. Figure 3As shown, if the infusion control device is applied to an infusion workstation / infusion central station, and the infusion control is performed by the infusion workstation / infusion central station, the infusion control method of this application may include:

[0095] S301. Obtain the rise time of the second infusion device; wherein, the rise time is the time required for the second infusion device to reach the target infusion rate from the start of infusion.

[0096] S302. Determine the infusion end time of the first infusion device.

[0097] S303. At least before the rise time from the end of the infusion time, output a pre-start prompt message to the second infusion device.

[0098] The specific implementation of steps S301 to S303 is similar to that of steps S101 to S103, and will not be described again here.

[0099] S304. When the second infusion device reaches the target infusion rate and the first infusion device finishes infusion, control the second infusion device to continue infusion.

[0100] For example, if the first infusion device and the second infusion device are continuously infusing, the infusion workstation / infusion central station, etc., can also control the second infusion device to continue infusing at the target infusion rate after determining that the second infusion device has reached the target infusion rate and the first infusion device has finished infusing.

[0101] The target infusion speeds of the first infusion device and the second infusion device can be the same or different. If they are the same, the entire infusion process can be carried out at a stable speed, thereby improving infusion safety. If they are different, the flow rate fluctuation difference caused by switching infusion devices can be reduced, and a relatively stable output process can be achieved, thereby improving infusion safety.

[0102] The infusion control method provided in this application includes: acquiring the rise time of a second infusion device; wherein the rise time is the time required for the second infusion device to reach a target infusion rate from the start of infusion; determining the infusion end time of a first infusion device; outputting a pre-start prompt message to the second infusion device at least before the rise time from the end of the infusion time; and controlling the second infusion device to perform infusion after the second infusion device reaches the target infusion rate and the first infusion device finishes infusion. This infusion control method can automatically control the second infusion device to start infusion at the target infusion rate after the first infusion device finishes infusion, avoiding large speed fluctuations during the connection of infusion devices. This allows for continuous and uninterrupted infusion at a desired and relatively stable infusion rate during continuous infusion, reducing the probability of significant changes in the patient's vital signs and improving infusion safety.

[0103] Figure 4 This application provides a schematic flowchart of another infusion control method. The infusion control method provided in this embodiment is applied to a second infusion device in an infusion system. The infusion system includes a first infusion device and a second infusion device.

[0104] When n (n≥2) infusion devices are involved in continuous steady-state infusion, the infusion control method provided in this embodiment can also be applied to other subsequent infusion devices besides the first infusion device, thereby realizing continuous steady-state infusion of multiple infusion devices.

[0105] like Figure 4 As shown, the infusion control method provided in this embodiment includes:

[0106] S401, Obtain the target infusion rate.

[0107] For example, the second infusion device first obtains its own target infusion rate, which can be set by the user when setting parameters; if it is the same as the target infusion rate of the first infusion device, it can also be obtained by the first infusion device when synchronizing information, and this application does not impose any restrictions.

[0108] S402. Based on the target infusion rate and preset calculation rules, determine the rise time to reach the target infusion rate.

[0109] For example, after obtaining its own target infusion rate, the second infusion device can determine the rise time to reach the target infusion rate based on the target infusion rate and preset calculation rules.

[0110] The rise time is related to one or more of the following: the drive parameters of the second infusion device, the specifications of the syringe connected to the second infusion device, and the target infusion rate.

[0111] For example, the driving parameters of the second infusion device are inherent parameters characterizing the infusion device's ability to drive the drug solution. These parameters are related to both the driving distance parameters of the infusion device, such as transmission clearance and pusher clearance, and the driving force parameters, such as driving force, driving power, and device rigidity. Due to machining errors, the driving parameters of each infusion device will vary to some extent, which can be obtained through testing and calibration before leaving the factory. The specifications of the syringe may include parameters such as the syringe's diameter, length, and capacity, or a comprehensive set of parameters determined by these parameters.

[0112] For example, the preset calculation rule can be calculated by a preset calculation formula, which can be Equation (1). Its specific implementation has been described in the foregoing embodiments and will not be repeated here.

[0113] S403, Output rise time to the first infusion device.

[0114] For example, after the second infusion device determines the rise time, it also outputs the rise time to the first infusion device. Based on the rise time sent by the second infusion device, the first infusion device can determine the time required for the second infusion device to start infusion until the infusion rate reaches the target infusion rate, thereby determining when to send a pre-start prompt message to the second infusion device.

[0115] The first infusion device and the second infusion device are connected via wired and / or wireless means. For example, the second infusion device can directly output the rise time to the first infusion device, or it can first send the rise time to the infusion workstation / infusion central station, and then the infusion workstation / infusion central station forwards it to the first infusion device. This application does not impose any restrictions.

[0116] In some examples, the infusion control method provided in this embodiment further includes:

[0117] Perform a pre-start based on the received pre-start prompt message.

[0118] For example, the pre-start prompt message is issued before the rise time of the infusion end time of the first infusion device. After receiving the pre-start prompt message, the second infusion device performs a pre-start so that the second infusion device reaches the target infusion rate before the first infusion device ends infusion.

[0119] In some examples, the infusion control method provided in this embodiment further includes:

[0120] When the actual infusion rate reaches the target infusion rate, a notification message indicating that the target has been met is output.

[0121] For example, when the actual infusion rate of the second infusion device reaches the target infusion rate, it can also output a compliance prompt message to indicate to the first infusion device or relevant personnel that the actual infusion rate of the second infusion device has reached the target infusion rate and the device can be switched.

[0122] The infusion control method provided in this embodiment is applied to a second infusion device in an infusion system. The infusion system includes a first infusion device and a second infusion device. The method acquires a target infusion rate and, based on the target infusion rate and preset calculation rules, determines the rise time to reach the target infusion rate; and outputs the rise time to the first infusion device. Therefore, based on the rise time sent by the second infusion device, the first infusion device can determine the time required for the second infusion device to reach the target infusion rate from the start of infusion, thereby determining the time to send a pre-start prompt message to the second infusion device. This ensures that the second infusion device reaches the target infusion rate before the first infusion device finishes infusion. Accordingly, when switching to the second infusion device after the first infusion device has finished infusion, the second infusion device can directly start infusion at the target infusion rate, thus avoiding large speed fluctuations that may occur when switching to the second infusion device. This allows for continuous and uninterrupted infusion at a desired and relatively stable infusion rate during continuous infusion, reducing the probability of significant changes in the patient's vital signs and improving infusion safety.

[0123] Furthermore, in the various medical electronic devices involved in the steady-state infusion control described in this application, such as the first infusion device, the second infusion device, the infusion workstation, and the infusion central station, each device may also include a display screen, and the infusion control method of this application may also include:

[0124] The infusion information is displayed on the screen; the infusion information includes one or more of the following: infusion trend graph, infusion sequence information, infusion status information, infusion end time, and rise time.

[0125] For example, the infusion trend graph is used to characterize the trend of actual infusion rate with infusion time; the infusion sequence information is used to indicate the infusion sequence of each infusion device; and the infusion status information is used to indicate the infusion status of each infusion device.

[0126] For example, Figure 5 An infusion trend graph is provided as an embodiment of this application. For example... Figure 5 As shown, infusion trend line A represents the infusion rate of the first infusion device as a function of infusion time, and infusion trend line B represents the infusion rate of the second infusion device as a function of infusion time; the horizontal axis represents infusion time, and the vertical axis represents infusion rate. The first infusion device's infusion rate increases from 0 to the target infusion rate v1, and then infuses at v1 until the infusion ends. The second infusion device begins pre-starting before the first infusion device finishes infusion. When the first infusion device finishes infusion, the second infusion device's infusion rate has already reached the target infusion rate v2. Therefore, when switching to infusion from the second infusion device, it directly infuses at v2.

[0127] Furthermore, infusion trend lines A and B can be displayed as follows: Figure 5 The data shown can be displayed under two different coordinate systems, or it can be displayed under the same coordinate system; this application does not impose any restrictions on this. Furthermore, v1 and v2 can be the same or different; this application does not impose any restrictions on this either.

[0128] For example, Figure 6 This is a schematic diagram of an infusion interface applied to a first infusion device, provided as an embodiment of this application. Figure 6 As shown, in the infusion interface 600, the content pointed to by label 11 is "Steady State 1," indicating that the interface of this display shows the infusion information of the first infusion device in a steady-state infusion state. In speed mode, the drug being infused by the first infusion device is norepinephrine, with an infused volume of 22.23 ml, a remaining volume of 28.77 ml, a remaining time of 02:00:12, and an infusion rate of 10.0 ml / h.

[0129] In addition, the interface 600 can also display basic information such as network connection information, current time information, remaining battery power information, patient bed number, and infusion end time; the infusion end time can be determined by the current time information and the remaining infusion time; the interface 600 can also be equipped with controls such as fast forward and pause for user control; this application does not impose any restrictions. When the content steady state 1 pointed to by label 11 does not exist or is displayed as "none", it indicates that there are no other devices that need to continue infusion after the first infusion device has finished infusion.

[0130] For example, Figure 7 This is a schematic diagram of an infusion interface applied to a second infusion device, provided as an embodiment of this application. Figure 7 As shown, in the infusion interface 700, the content pointed to by label 12 is steady state 2, indicating that the interface of this display screen shows the infusion information of the second infusion device. Based on the display status of the hourglass icon 120 in the figure, it can be determined whether it is in a pre-start state, an infusion waiting state, or an infusion in progress state. Figure 7 The diagram shows the infusion interface of the second infusion device when entering the pre-start state. At the instant of entering the pre-start state, the infused volume is 0.00 ml, the remaining volume is the same as the preset volume (50.00 ml), the remaining time is still 05:00:00, and the infusion rate is also 0.0 ml / h. After entering the pre-start state, the hourglass icon 120 in the diagram changes to a vertical dynamic shape.

[0131] For example, Figure 8 This is a schematic diagram of another infusion interface applied to a second infusion device, provided as an embodiment of this application. Figure 7Based on the interface shown in the pre-startup state, once the pre-startup is complete, i.e., the infusion rate reaches the target infusion rate, the interface will change to the one shown below. Figure 8 The infusion interface 800 shown indicates that the second infusion device is in an infusion waiting state. During the waiting process, the hourglass icon 121 is horizontally static. After completing the pre-start and entering the waiting state, the infused volume becomes 01.50 ml, the remaining volume becomes 48.50 ml, the remaining time becomes 04:50:00, and the infusion rate changes to the target infusion rate of 10.0 ml / h. Based on the change in the remaining time, the rise time can be determined to be 10 minutes, which can also be displayed on the interface; this application does not impose any restrictions.

[0132] For example, Figure 9 This is a schematic diagram of another infusion interface applied to a second infusion device, provided as an embodiment of this application. Figure 8 Based on the interface shown in the infusion waiting state, after the first infusion device completes its infusion, it switches to the second infusion device to continue infusion at the target infusion rate, and the interface changes to the one shown in the image. Figure 9 The infusion interface 900 is shown. At this time, the second infusion device is in the infusion state. During the infusion process, the hourglass icon 122 in the figure is vertically dynamic. After entering the infusion state, the volume entered, the remaining volume, and the remaining time change as the infusion progresses. The figure shows that the volume entered becomes 22.23 ml, the remaining volume becomes 28.77 ml, and the remaining time becomes 02:00:12. The infusion rate (flow rate) is stabilized at the target infusion rate of 10.0 ml / h.

[0133] In some examples, the display interface may also show an infusion trend chart. For example, Figure 10 This is a schematic diagram illustrating the transformed information displayed on an input interface, as provided in an embodiment of this application. If the user... Figure 9 When you tap the remaining time in the displayed interface, the content displayed in that area will change as shown below. Figure 10 The infusion trend chart 100 is shown. Additionally, other areas of the chart can be clicked to display other information; this application does not impose any restrictions.

[0134] Among them, the above Figures 5-10 The examples described are merely a few examples of what can be achieved in this application, and the specific values ​​of the parameters in the figures are also just examples and should not be considered as limitations on this application. Furthermore, in addition to the information already shown in the figures, more information can be displayed according to actual needs, such as the personnel setting parameters, medical staff on-duty information, etc., to fully display all key information and facilitate medical staff in viewing and obtaining data.
