Description

Infusion pump and interface operation method of infusion pump

Technical Field

The present application relates to the field of medical imaging technology, and more particularly, to an infusion pump and an interface operation method of the infusion pump.

Background

An infusion pump is an intelligent infusion device, and is special medical equipment which utilizes mechanical driving force to accurately control the number of infusion drops or the flow rate of infusion and ensures that the infusion pump can accurately and safely enter the body of a patient. The infusion pump is clinically applied, so that the accuracy, safety and nursing quality of infusion are greatly improved.

Infusion pumps typically provide a visual interface via a display screen for user interaction to accomplish parameter setting and operational monitoring of the infusion pump. Because the infusion pump volume is less, therefore less area of display screen, infusion information can't obtain effectual presentation, and the operation is inconvenient, and user experience is not good.

In order to provide a thorough understanding of the present application, a detailed structure will be presented in the following description in order to explain the technical solutions presented in the present application. Alternative embodiments of the present application are described in detail below, however, the present application may have other implementations in addition to these detailed descriptions.

As shown in FIG. 1, an embodiment of the present invention provides an infusion pump 100 that includes a processor 110, a display system 120, and a drive device 130. Of course, the infusion pump may also include other components, such as a pump body, a reservoir, sensors, etc. The infusion pump 100 is used for drug infusion with infusion tube consumables or syringe consumables, such that fluid substances in the infusion tube consumables or syringe consumables are directionally delivered to a patient under the driving of the driving device 130 of the infusion pump. The infusion pump can comprise a syringe pump or an infusion pump, wherein when the infusion pump is the syringe pump, the corresponding consumable is a syringe consumable; when the infusion pump is an infusion pump, the corresponding consumable is the consumable of the infusion tube.

In the case of a syringe pump, the pump body has a mounting structure for mounting a syringe, for example, by holding the syringe barrel of the syringe in a certain position by a holding structure. The mounting structure includes, but is not limited to, a clamping structure, a magnetic attraction structure, a snap structure, and the like. The driving device 130 is used to move the piston rod of the syringe to inject liquid, for example, by pushing the piston rod of the syringe through a push rod. The driving device 130 may generally adopt a motor as a power unit, wherein the motor converts the selective motion into a linear motion via a transmission mechanism, so as to push the piston rod of the syringe to move and squeeze the liquid in the syringe. By setting the rotational speed of the motor, the speed at which it advances the mating syringe can be adjusted, thereby adjusting the dosage and rate of medication administered. Of course, the driving device 130 may be a power unit capable of outputting linear motion, such as an air cylinder, in addition to the motor.

The processor 110 is used for controlling the driving device 130. The processor 110 may also include a peripheral interface. The processor 110 may be configured to send instructions to the driving apparatus 130, and the peripheral interface may be connected to a peripheral device such as the display system 120 for signal transmission, so that the processor 110 controls the driving apparatus 130 according to the user's intention.

The display system 120 has a display screen capable of displaying information, wherein at least a partial area of the display screen is a touch display screen, which is connectable to the processor 110 and capable of both displaying information and receiving touch commands from a user. Illustratively, the processor 110 outputs a touch screen driving signal for driving the touch screen and display screen image information for causing the display screen to display an image. The display screen can be arranged on the pump body and also on the pump door.

On the other hand, the infusion pump 100 may be implemented as an infusion pump for driving an infusion tube to perform infusion at a set time and flow rate. For the infusion pump, the pump body is provided with a placing position for placing the infusion tube, and is also provided with a liquid stopping structure for installing the infusion tube and cutting the infusion tube in a non-working stage, for example, a liquid stopping clamp is used for placing a large amount of liquid in the infusion tube to enter the human body. The driving device 130 is used for driving the liquid flow in the infusion tube. The driving device 130 may be a peristaltic pump or other device capable of driving the movement of the liquid in the infusion tube. The user sets the infusion parameters according to the order of the doctor through the display system 120 of the infusion pump, and the processor 110 automatically converts the operation parameters of the driving device 130 to drive the liquid in the infusion tube to continuously flow in a directional manner, thereby achieving the purpose of constant-speed quantitative infusion.

The display system 120 of the infusion pump 100 provides a plurality of visual interfaces for display in the display screen of the infusion pump 100 after the infusion pump 100 is powered on until the infusion pump 100 is powered off. Before the infusion pump 100 is started to perform infusion, the display content of the visual interface provided by the display system 120 includes at least two of infusion parameter information, infusion state information, device state information, infusion alarm information, and infusion operation controls, where the infusion parameter information includes first infusion parameter information, that is, core infusion parameter information that is most concerned in the current state; and displaying the first infusion parameter information at a visual focusing position of a visual interface, wherein the first infusion parameter information is a preset default parameter value or a parameter value associated with a latest editing event or a latest infusion parameter import event.

After the infusion pump 100 is started to perform infusion, the display content of the visual interface provided by the display system 130 still includes at least two of infusion parameter information, infusion state information, device state information, infusion alarm information, and infusion operation controls, and the infusion parameter information includes first infusion parameter information; the same visual focus position of the visual interface still displays the first infusion parameter information, and when the infusion state of the infusion pump changes, the latest infusion state information is displayed in the visual focus position. Wherein the visual focus position before the infusion pump 100 is initiated for infusion and the visual focus position after the infusion pump 100 is initiated for infusion are located at the same position on the visualization interface.

Therefore, the first infusion parameter information and the latest infusion state information are always displayed at the same visual focusing position of the visual interface, so that the user can pay attention to and find the most concerned information in each infusion stage more easily, and the user experience is improved.

The infusion parameter information mainly comprises setting parameter information and monitoring parameter information. Before the infusion pump 100 is started to perform infusion, the infusion parameter information displayed in the visual interface is mainly set parameter information, such as drug name, flow rate, consumable, volume to be infused and the like; the setting parameter information can be set by the user, and default parameters can also be adopted.

When the infusion pump 100 is initiated for infusion, the infusion parameter information displayed in the visual interface includes both set parameter information and monitoring parameter information including, for example, occlusion pressure, volume accessed, etc. The infusion state information indicates the progress state of infusion, such as start, pause, push, and the like. The device status information is the status of the infusion pump itself, such as network status, power status, etc. The infusion alarm information is displayed when the processor 110 detects an alarm event including, but not limited to, the presence of a bubble in the tubing detected by the bubble sensor, the medical fluid being near empty or already empty, an occlusion in the infusion, etc. The infusion operation control is an operable icon provided to the user to change the infusion state, such as push, pause, start, etc. Each of the above information items may be represented in any form such as text, graphics, or a combination of text and graphics, which is not limited in this embodiment of the present invention.

The display system 120 of the infusion pump 100 provides a plurality of visual interfaces including a visual focus location for displaying the first infusion parameter information of the infusion parameter information, i.e., the most important information for each stage, after the infusion pump 100 is powered on and before the infusion pump 100 is powered off. Illustratively, the first infusion parameter information for each stage is at least partially identical. The display system 120 is also configured to display the latest infusion state information in the visual focus position when the infusion state of the infusion pump 100 changes. The visual focus position may be a visual center position, and specifically may be a center position in an up-down direction or a center position in a left-right direction in the visual interface. Displaying the first infusion parameter information in the visual focus position may make it easier for the user to see the information that is most interesting at the current stage. Depending on the construction and operating habits of the infusion pump, in one embodiment, the visual focus position is located to the left of the visualization interface, i.e., the position that is most easily focused on by the user.

Illustratively, the changing of the infusion state of the infusion pump 100 includes: the infusion state of the infusion pump 100 is changed from the operating state to the pause state, the state of the infusion pump 100 is changed from the operating state to the push-fast state, the state of the infusion pump 100 is changed from the pause state to the push-fast state, the infusion state of the infusion pump 100 is changed from the pause state to the KVO (keep vein open) state, the infusion state of the infusion pump 100 is changed from the pause state to the exhaust state, and the infusion state of the infusion pump 100 is changed from the pause state to the standby state. That is, only in the normal infusion state, the visual focus position may not display the infusion state information, but only the first infusion parameter information. And under other special states such as pause, fast push, KVO and the like, the visual focusing position displays the transfusion state information so as to prompt the user to pay attention to the change of the transfusion state.

In another embodiment, during a normal infusion state, the visual focus position of the operator interface may also display infusion state information indicating that an infusion is currently being performed. Illustratively, the infusion pump 100 may also include an output device such as an indicator light, a speaker, etc., which may output infusion status information via the output device such as the indicator light, the speaker, etc.

When the latest infusion state information is displayed at the visual focusing position, the latest infusion state information can be displayed instead of at least part of the first infusion parameter information, for example, under an alarm interface, the visual focusing position can only display 'pause' and no part of the first infusion parameter information (such as flow rate) is displayed; meanwhile, the rest part of the first infusion parameter information (such as the drug name) can be reserved. Or, in some infusion states, the core infusion state information is still one of the most concerned information, and the latest infusion state information is displayed simultaneously with the first infusion parameter information. For example, in the pause interface, the latest infusion state information (i.e., "pause") and first infusion parameter information (e.g., flow rate information) are displayed together in a visual focus position.

Further, the infusion parameter information further includes second infusion parameter information, i.e. non-core infusion parameter information other than the first infusion parameter information. Illustratively, the plurality of second infusion parameter information of the visual interface can be switched and displayed according to touch gestures, wherein the touch gestures include a contact gesture and a non-contact gesture, and the touch gestures can be up-down, left-right or any direction sliding gestures. By switching the display mode, all infusion parameter information can be completely presented while the font size is ensured.

Illustratively, the visual interface comprises a first parameter area for displaying first infusion parameter information, a second parameter area for displaying second infusion parameter information and an operation area for displaying infusion operation controls, wherein the first parameter area is positioned at a visual focusing position so as to facilitate a user to focus on the first infusion parameter information; the first parameter area, the second parameter area and the operation area are independent of each other and can be independently operated. For example, when the second infusion parameter information in the second parameter area is switched and displayed according to the touch gesture, the core infusion parameter area and the operation area are not affected, that is, the information in the other two areas is not affected by the touch gesture.

Illustratively, the plurality of visualization interfaces includes a plurality of visualization interfaces in a first infusion mode and a plurality of visualization interfaces in a second infusion mode, and the processor 110 of the infusion pump 100 determines to display the plurality of visualization interfaces in the first infusion mode or the plurality of visualization interfaces in the second infusion mode based on the latest edit event or the latest infusion parameter import event, wherein a first infusion parameter item of the plurality of visualization interfaces in the first infusion mode and a first infusion parameter item of the plurality of visualization interfaces in the second infusion mode are at least partially different. Illustratively, the first infusion mode includes a speed mode and the second infusion mode includes a weight mode. It should be noted that the selectable infusion modes of the infusion pump 100 are not limited to two, and may include more infusion modes, and the first infusion parameter items corresponding to different infusion modes may be the same or at least partially different.

For ease of understanding, fig. 3A, 3B, and 3C illustrate examples of a visual interface provided by the display system 120 before the infusion pump 100 is initiated for infusion in the speed mode, the weight mode, and the sequence mode, respectively, which is a parameter setting interface, configured as a master, primarily for receiving touch commands from a user and setting parameters. Fig. 4A and 4B respectively show an example of a visual interface provided by the display system 120 after the infusion pump 100 is started to infuse in the speed mode, the weight mode and the sequence mode, where the visual interface is an operation interface, mainly for browsing and mainly for presenting various parameters needing attention to the user. The first infusion parameter item in the speed mode and the first infusion parameter item in the weight mode are at least partially different: in the speed mode, the first infusion parameter item comprises a drug name item and a flow rate item; in the weight mode, the first infusion parameter items include a drug name item, a flow rate item, and a dose rate item.

For the parameter setting interface, referring to fig. 3A, the first parameter area is located at the visual focus position, i.e., the middle part of the left side of the interface, and is used for displaying the core infusion parameters, i.e., the drug name, the flow rate, the mode and the consumable, wherein the drug name and the flow rate are displayed in close proximity, so that the core infusion parameters are clearly visible and convenient to observe. The non-core transfusion parameter area is positioned on the right side of the visual interface and is used for displaying non-core transfusion parameters, namely preset quantity and preset time; if the types of the non-core infusion parameters are more, the second infusion parameter information can be switched and displayed according to the touch gesture, and the first parameter area and the operation area are not affected when the second parameter area is operated. The operation area is positioned below the first parameter area and the second parameter area and is used for displaying infusion operation controls, namely fast pushing and starting.

When the processor 110 detects a selection instruction of each infusion parameter item in the parameter setting interface, entering an editing interface of the corresponding infusion parameter item. Continuing with fig. 3A, taking the flow rate as an example, if the processor 110 detects a touch selection of the flow rate item, the control display system 120 switches the parameter setting interface to a flow rate editing interface for receiving a flow rate value input by the user. The flow rate editing interface displays the type of current editing interface (i.e., displays "flow rate"), numeric keypad, units of flow rate (e.g., ml/h), and determine and cancel options. For example, when the flow rate value input by the user is displayed in the input box, the size of the number after the decimal point may be displayed to be smaller than the size of the number before the decimal point to prompt the user to pay attention to the decimal point.

Illustratively, after obtaining the flow rate value entered by the user, a unit edit interface is provided for display on the display screen to ask the user to determine the flow rate unit or the dosage rate unit, or to switch the flow rate unit or the dosage rate unit. This can reduce the occurrence of a unit setting error.

In some embodiments, the display system 120 may also display a preset flow rate threshold in the flow rate editing interface, for example, the threshold may be displayed in a top area of the flow rate editing interface. After receiving a confirmation instruction of the current input flow rate value and flow rate unit from the user, comparing the current input flow rate value with a preset flow rate threshold, if it is detected that the current input flow rate value exceeds the preset flow rate threshold, the display system 120 may pop up a prompt box on the display screen to prompt the user that the current input flow rate exceeds the preset flow rate threshold, and ask the user whether to accept the current input flow rate value, thereby avoiding a situation of parameter input error.

In the weight mode, referring to fig. 3B, the first infusion parameter items include a flow rate item and a dose rate item, wherein the dose rate item is an editable item and the flow rate item is a non-editable item, which are calculated by the processor 110 according to the dose rate and the weight, and the calculation result is displayed in the first parameter area together with the dose rate item. Thus, in the weight mode, the flow rate term may be displayed differently from the dose rate term to prompt the user to edit the dose rate term.

In addition to the first infusion parameter item, the display system 130 also displays a corresponding editing interface when it is detected that the user clicks on the second infusion parameter item. The editing interfaces for different infusion parameter items may have different forms, for example the time editing interface may display a scrolling time scale.

Referring to fig. 3C, for the sequence mode, the parameter setting interface may provide settings for a plurality of sequences, i.e., set the infusion parameter information of each sequence separately; the first parameter area may also display the sequence number, which the user may add or delete by clicking on. In the sequence mode, the visual focus position of the running interface may also display the current serial number, see fig. 4C.

Referring to fig. 3A, 4A, the first parameter zone operating region has a first area before the infusion pump is initiated to infuse; the first parameter zone operating region has a second area after the infusion pump is initiated for infusion; wherein the first area is larger than the second area. Optionally, the first parameter zone has a third area before the infusion pump is initiated for infusion and a fourth area after the infusion pump is initiated for infusion, the fourth area being greater than the third area. That is, since the operation interface is viewed mainly, after the infusion pump is started to infuse, the area of the first parameter region becomes large, and the area of the operation region becomes small, so that more information focused by the user is presented through a limited visualization interface.

In some embodiments, the first infusion parameter item before the infusion pump is initiated to infuse is partially hidden after the infusion pump is initiated to infuse. With continued reference to fig. 3A, 4A, before the infusion pump is initiated to infuse, in the setup interface, the first infusion parameter items include drug name, flow rate, consumable, and mode; when the infusion pump is started to infuse, the infusion pump enters an operation interface, the first infusion parameter item only comprises the drug name and the flow rate, and the first infusion parameter item is moved out of the first parameter area because the mode and the consumable item cannot be changed and are not focused any more, so that the first infusion parameter item and the consumable item hide and weaken the two items of information, space is released for the drug name and the flow rate information which need to be focused by a user under the operation state, and the information which is focused by the user is displayed at the limited visual focusing position.

In one embodiment, prior to providing the parameter setting interface, the display system 120 first provides a medication selection interface. The drug selection interface is used for setting drug names, and the parameter setting interface is used for setting options of infusion parameter information different from the drug names, wherein the options include first infusion parameter information and second infusion parameter information. Fig. 2 shows a schematic diagram of a drug selection interface.

Illustratively, the drug selection interface may support quick drug selection. In the drug selection interface, a plurality of commonly used drug name options may be provided, and the user may click on the drug name option to select it as the target drug. After the user selects the target drug, the user can directly enter the next interface, namely the parameter setting interface.

Further, the drug name options may be classified according to drug types to increase the speed of finding the target drug by the user, and the drug classifications may include common drugs, sedatives, analgesics, anesthetics, and the like. With continued reference to fig. 2, a drug classification option may be displayed above the drug selection interface, clicking on the corresponding drug classification, and the usual drugs of that type may be displayed below it. Because the medicine type is more, and the display screen of infusion pump is less, therefore the medicine name can switch to show according to the touch gesture.

Illustratively, the drug selection interface may also support retrieval. In particular, a retrieval option may be provided on the drug selection interface, with the retrieval option displayed to the right of the drug classification option in fig. 2. When a touch instruction of a user is received through the retrieval option, an alphabet can be displayed, and when the user selects a corresponding letter, a medicine name containing the letter is displayed in the medicine selection interface.

The infusion operation controls displayed in the drug selection interface may include a push control and a skip (or exit) icon. Clicking the fast push control to enter a fast push interface, clicking the skip control to skip (or quit) the medicine selection operation, and entering a parameter setting interface. If the selected medicine name is entered into the parameter setting interface after the medicine name is selected, displaying the selected medicine name in the parameter setting interface; otherwise, if the user enters the parameter setting interface after skipping the medicine selection operation, displaying the information of the unselected medicines in the parameter setting interface.

Illustratively, upon entering the parameter setting interface, if the processor of the infusion pump does not detect a new editing event, at least part of the infusion parameter information of the parameter setting interface is displayed as preset default parameters associated with the name of the drug selected in the drug selection interface. That is, after entering the parameter setting interface, some or all of the infusion parameter information except the drug name is first displayed as the default parameters associated with the selected drug, and then, if an editing event for a certain infusion parameter information is detected, the default parameters are replaced with the newly edited parameters. Therefore, the speed and efficiency of parameter setting can be further improved, and the operation is further simplified.

Referring to fig. 5, the plurality of visualization interfaces further includes a pause interface. When the infusion pump 100 enters the pause state, the display system 120 provides a pause interface display in the display screen of the infusion pump 100. In the pause interface, the visual focus position displays the latest infusion state information, namely, the pause state information. In addition, the first infusion parameter information may be displayed in parallel with the infusion state information while still being displayed at the visual focus position. Meanwhile, the second infusion parameter information and the operation control can be kept at the original position. The operation controls in the pause state are a fast push control and a start control, and when receiving a touch operation on the fast push control, the display system 130 displays a fast push parameter editing interface; when a touch operation on the start control is received, the processor 110 controls the driving device 130 to start infusion.

Referring to FIG. 6, the plurality of visualization interfaces further includes a push interface. When the infusion pump 100 enters the push-through state, the display system 120 provides a push-through interface that is displayed in a display screen of the infusion pump 100. In the fast-push interface, the visual focusing position displays the latest infusion state information, namely the fast-push state information. In addition, the first infusion parameter information may be displayed in parallel with the infusion state information while still being displayed at the visual focus position. Meanwhile, the second infusion parameter information and the operation control can be kept at the original position. The operation controls in the fast-pushing state are a fast-pushing control and an exit control, and when receiving a touch operation on the fast-pushing control, the processor 110 controls the driving device 130 to start fast-pushing; and when the touch operation of the exit control is received, exiting the fast push interface.

After the infusion pump 100 is initiated for infusion, if the processor 110 of the infusion pump 100 detects an alarm event, the processor 110 controls the display system 120 to provide an alarm interface for display in a display screen for displaying alarm information. The visual focusing position of the alarm interface is used for displaying the infusion state information. Referring to fig. 7, since the processor 110 controls the driving device 130 to suspend infusion when an alarm event is detected, the infusion state information displayed at this time may be "suspended".

In addition, the display content of the alarm interface at least comprises at least one of an alarm reason and an operation prompt. Illustratively, the cause of the alarm may be displayed in a highlighted display at the top of the alarm interface, such as "drip rate anomaly", "lower blockage", "accumulated bubbles", or the like. The operation prompt can replace the non-core infusion parameters, namely, the operation prompt is displayed in the original second parameter area, for example, if the alarm reason is 'dripping speed is abnormal', the corresponding operation prompt can be displayed as 'please check the dripping speed sensor or adjust the threshold value'; if the alarm reason is 'lower blockage', the corresponding operation prompt can be displayed as 'please check the pipeline or adjust the threshold'; if the alarm is caused by 'pipeline bubble', the corresponding operation prompt can be displayed as 'please remove the bubble', etc. For example, when the operation prompt is displayed, a setting option can be provided on the alarm interface at the same time, for example, when the operation prompt of "please check the drop speed sensor or adjust the threshold" is displayed, a drop number setting option for adjusting the threshold can be provided on the alarm interface at the same time.

In some embodiments, the display content of the alert interface may also include an alert graphic. Wherein the alarm graphic can be used to present the reason for the alarm. For example, if the alarm reason is an upper blockage, an alarm graphic representation of the pipeline blockage can be displayed; if the alarm reason is pipeline bubbles, an alarm graphic representation of the bubbles appearing in the pipeline can be displayed; the reason for the alarm can thus be presented intuitively. Alternatively, the cause of the alarm is used to present an operational prompt, i.e., how to exclude the factor that caused the alarm. For example, if the operation prompt is to connect the dripping speed sensor, an alarm graphic of how to connect the dripping speed sensor can be displayed; this can help the user intuitively understand how to specifically exclude the factors that trigger the alarm.

For example, the alarm interface may be classified into a low-level alarm interface and a high-level alarm interface according to the reason of the alarm. Wherein, the high-level alarm interface can display an alarm graphic, and the low-level alarm interface can not display the alarm graphic. In addition, the low-level alarm interface may not override the non-core infusion parameter information, and even when a low-level alarm is triggered, the infusion pump 100 may not enter a pause state, so the low-level alarm interface may not display pause state information, only display the reason for the alarm, and simultaneously display the alarm reset and alarm tone pause operational controls.

Illustratively, the alarm interface also includes a KVO (keep vein open) alarm interface. The display content of the KVO alarm interface comprises transfusion state information representing the KVO state; the display content of the KVO alarm interface also comprises infusion parameter information and an infusion operation control.

Illustratively, the plurality of visual interfaces further includes an exhaust interface, and the user may enter an exhaust mode through an exhaust control in the menu bar, and the processor 110 controls the driving device 130 to exhaust. The display content of the exhaust interface at least comprises infusion state information representing the exhaust state.

In one embodiment, if the processor 110 does not detect the touch operation of the user within a period of time, the display system 110 is controlled to display the visual interface in the screen-locking state to prevent the occurrence of a false touch. Exemplarily, in a visual interface in a screen locking state, an unlocking control is displayed in an operation area to cover an original operation control; except for the operation area, the display content of other areas is the same as the operation interface or the parameter setting interface, but the user does not enter the editing interface in the screen locking state, namely the user cannot edit the content in the editing interface. And when the touch operation of the user on the unlocking control is received, the screen locking state is released.

In summary, the infusion pump of the embodiment of the invention can better realize user interaction through a limited display interface, improve user experience, and simplify infusion operation.

With continued reference to fig. 1, another aspect of an embodiment of the present invention provides an infusion pump 100 that includes a processor 110, a display system 120, and a drive arrangement 130. The infusion pump 100 is used for drug infusion with infusion tube consumables or syringe consumables, wherein the processor 110 controls the driving device 130 to drive the fluid substance in the infusion tube consumables or syringe consumables, so that the fluid substance is directionally delivered to the patient body under the driving of the driving device 130. The display system 120 of the infusion pump 100 provides a plurality of visual interfaces to be displayed on the display screen of the infusion pump 100 after the infusion pump 100 is powered on and before the infusion pump 100 is powered off, and the plurality of visual interfaces are switched according to the operating state of the infusion pump 100. The display content of the visual interface comprises at least two of infusion parameter information, infusion state information, equipment state information, infusion alarm information and an infusion operation control; the infusion parameter information comprises first infusion parameter information, and the first infusion parameter information is kept in the same area in the switching process of the plurality of visual interfaces.

Wherein, the switching process of the plurality of visual interfaces can be switching caused by the change of the infusion state. Referring to fig. 3A, 4A, wherein fig. 3A shows a parameter editing interface before the infusion pump 100 is started to infuse, the first infusion parameter information including drug name information and flow rate information is displayed on the left side of the visualization interface; fig. 4A shows the operational interface after the infusion pump 100 is initiated, with the drug name information and flow rate information still remaining on the left side of the visual interface, where the user can find the flow rate information in any infusion state, thereby reducing learning time.

In addition, the switching process of the multiple visual interfaces may be switching due to a change in infusion mode. Referring to fig. 3A and 3B, wherein fig. 3A shows a parameter editing interface in a flow rate mode, first infusion parameter information comprises drug name information and flow rate information, and is displayed on the left side of a visual interface; fig. 3B shows the parameter editing interface in the weight mode, and the drug name information and the flow rate information are still maintained on the left side of the visual interface, and the user can find the drug name information and the flow rate information at the position in any infusion mode, so that the learning time is reduced.

Further, the infusion parameter information further comprises second infusion parameter information, and at least one piece of non-core parameter information is kept in the same area in the switching process of the plurality of visual interfaces. Referring to fig. 3A and 4A, in different infusion states, the second infusion parameter information is always kept on the right side of the visual interface; referring to fig. 3A and 3B, the second infusion parameter information is also always kept on the right side of the visual interface in different infusion modes. Further, the infusion operation control may also remain in the same area, such as the bottom of the visual interface, during switching of multiple visual interfaces. This can further reduce the learning time of the user.

In some embodiments, when the infusion state of the infusion pump 100 changes, the latest infusion state information is displayed in the same area. Referring to fig. 5 and 6, when the infusion state of the infusion pump 100 is changed to the pause state or the push-fast state, the infusion state information indicating the pause state or the push-fast state is displayed in the same area, which is advantageous for presenting the change in the infusion state to the user.

In one embodiment, the plurality of visualization interfaces includes a plurality of visualization interfaces in a first infusion mode and a plurality of visualization interfaces in a second infusion mode, and the processor 110 of the infusion pump 100 determines to display the plurality of visualization interfaces in the first infusion mode or the plurality of visualization interfaces in the second infusion mode based on the most recent editing event or the most recent infusion parameter import event. The first infusion parameter items of the plurality of visual interfaces in the first infusion mode are at least partially different from the first infusion parameter items of the plurality of visual interfaces in the second infusion mode. For example, referring to fig. 3A and 3B, the first infusion mode includes a speed mode, and the second infusion mode includes a weight mode, wherein the first infusion parameter item in the speed mode includes a drug name item and a flow rate item, and the first infusion parameter item in the weight mode includes a drug name item, a dosage rate item and a flow rate item, but the core infusion parameters in the two infusion modes keep information in the same area, so that the first infusion parameter information can be found in the same area after the modes are switched.

For more details on the infusion pump 100, reference may be made to the above description, which is not repeated here.

According to the infusion pump of the embodiment, the first infusion parameter information is always kept in the same area to be displayed in the switching process of the plurality of visual interfaces, so that the learning time of a user can be reduced.

The embodiment of the present invention further provides an infusion pump, and with continued reference to fig. 1, the infusion pump 100 includes a processor 110, a display system 120 and a driving device 130, the infusion pump 100 performs drug infusion in cooperation with a consumable infusion tube or a consumable syringe, and the processor 110 controls the driving device 130 to drive a fluid substance in the consumable infusion tube or the consumable syringe, so that the fluid substance is directionally delivered to a patient body under the driving of the driving device 130 of the infusion pump. The display system 120 of the infusion pump 100 is configured to provide at least a parameter setting interface and an operation interface to be displayed on a display screen of the infusion pump 100 after the infusion pump 100 is turned on and before the infusion pump 100 is turned off, and the parameter setting interface and the operation interface are switched with an operating state of the infusion pump, where display contents of the parameter setting interface and the operation interface both include at least two of infusion parameter information, infusion state information, device state information, infusion alarm information, and infusion operation control; the infusion parameter item of at least one infusion pump can be edited on the basis of touch operation in a parameter setting interface, so that the infusion parameter information of the infusion parameter item is adjusted, and the infusion parameter item cannot be edited on the basis of touch operation in the running interface; the position of the infusion parameter item on the parameter setting interface is different from the position of the infusion parameter item on the operation interface.

In one embodiment, the parameter setting interface and the operation interface include the same visual focus position, and the infusion parameter items are displayed in the parameter setting interface at the visual focus position and the infusion parameter items are displayed in the operation interface outside the visual focus position.

Illustratively, referring to fig. 3A, 4A, the infusion parameter items may include mode items and consumable items that are displayed in a visual focus location on the left side of the interface in the parameter setting interface for editing by the user; in the running interface, the mode item and the consumable item cannot be edited and no more important attention is needed, so that the visual focus position can be removed, and the mode item and the consumable item can be displayed on the top of the interface.

In one embodiment, the display system 120 of the infusion pump 100 is further configured to provide at least a pause interface for display in a display screen of the infusion pump 100 after the infusion pump 100 is powered on until the infusion pump 100 is powered off, the pause interface including the same visual focus location in which infusion parameter items are displayed in the pause interface. Referring to fig. 5, since the infusion parameter information in the pause interface may be edited based on a touch operation, the mode item and the consumable item may be newly displayed at the visual focus position for the user to edit.

In one embodiment, the display system 120 of the infusion pump 100 is further configured to provide at least an alarm interface for display in a display screen of the infusion pump 100 after the infusion pump 100 is powered on until the infusion pump 100 is powered off, the alarm interface including the same visual focus location, the infusion parameter items being displayed in the alarm interface outside of the visual focus location. Referring to fig. 7, since the infusion pump is in a suspended state during the alarm process, the infusion parameter information cannot be edited based on touch operation, the mode item and the consumable item can be hidden, and other information needing attention can be displayed by using the space of the visual interface.

The infusion pump according to the present embodiment displays infusion parameter items at different positions according to whether they can be edited or not, and displays them at positions favorable for editing when they can be edited; when the information can not be edited, the information can be displayed at the edge position so as to save space for displaying other information needing attention, and therefore more information which is focused by a user can be displayed through a wired visual interface.

Referring now to fig. 8, a method 800 of interfacing operation of an infusion pump in accordance with an embodiment of the present application is described. FIG. 8 is a schematic flow chart diagram of a method 800 of interface operation according to an embodiment of the present invention.

As shown in fig. 8, the method 800 of interfacing the infusion pump includes the steps of:

in step S810, after the infusion pump is turned on, providing a drug selection interface to be displayed in a display screen of the infusion pump, so as to receive a drug selection operation of a user through the drug selection interface;

in step S820, after the drug selection operation is received, or after an operation of skipping the drug selection interface is received, controlling to directly skip from the drug selection interface to a parameter setting interface, where the parameter setting interface is used to provide setting options of infusion parameter information, and display content of the parameter setting interface further includes an infusion operation control, where the infusion operation control at least includes an infusion start control;

in step S830, after receiving the touch operation on the infusion start control, the infusion pump starts infusion, so that the fluid substance in the infusion tube consumable or the syringe consumable is directionally delivered to the body of the patient under the driving of the driving device of the infusion pump; and in the infusion process, providing an operation interface to be displayed in the display screen, wherein the display content of the operation interface at least comprises infusion parameter information and an infusion operation control.

Exemplarily, the drug selection interface displayed in step S810 is as shown in fig. 9A. A drug type option may be displayed in the drug selection interface, and the user may first select a drug category and then select a drug name under that drug category. Optionally, a search option may also be displayed in the drug selection interface, when a touch instruction of the user is received through the search option, an alphabet may be displayed, and when the user selects a corresponding letter, a name of a drug including the letter is displayed in the drug selection interface. The infusion operation controls displayed in the drug selection interface may include a push-fast control and a skip (or exit) icon. Clicking the fast push control to enter a fast push interface, clicking the skip icon to skip (or quit) the medicine selection operation, and entering a parameter setting interface.

Next, in step S820, after receiving a selection instruction for the name of the drug, or after receiving an operation of skipping the drug selection interface, directly skipping to the parameter setting interface without going through other visual interfaces. The parameter setting interface is shown in fig. 9B. The parameter setting interface is used for providing setting options of infusion parameter information, and if the name of the selected drug is entered into the parameter setting interface after the name of the selected drug is selected, the name of the selected drug is displayed in the parameter setting interface; otherwise, if the user enters the parameter setting interface after skipping the medicine selection operation, displaying the information of the unselected medicines in the parameter setting interface. Illustratively, when a touch instruction for the medicine name is received, the control jumps back to the medicine selection interface from the parameter setting interface.

In one embodiment, the parameter setting options include at least a consumable setting option and an infusion mode setting option; the parameter setting options further include one of a flow rate setting option and a dose rate setting option. In the flow rate mode, the parameter setting options include a flow rate setting option; in the weight mode, the parameter setting options include a dose rate setting option.

And when receiving touch control instructions of different infusion parameter items of the parameter setting interface, controlling to display a corresponding editing interface. When touch operation on the flow rate setting option or the dosage rate setting option is received, an editing interface is provided and displayed in the display screen, so that the flow rate value or the dosage rate value input by a user can be received. For example, when a touch instruction for the flow rate item is received, first, a flow rate editing interface as shown in fig. 9C is skipped to receive a flow rate value input by a user. The flow rate editing interface displays a numeric keypad, flow rate units, and go options icons.

After the flow rate value or the dosage rate value input by the user is obtained, a unit editing interface is provided to be displayed in the display screen so as to require the user to determine the flow rate unit or the dosage rate unit. Illustratively, after the flow rate value input by the user is obtained in the flow rate editing interface shown in fig. 9C, a unit editing interface shown in fig. 9D is provided to be displayed in the display screen to ask the user to determine the flow rate unit or the dose rate unit or to switch the flow rate unit or the dose rate unit. This can reduce the occurrence of a unit setting error.

In some embodiments, after receiving a confirmation instruction of the user for the currently input flow rate value and the currently input flow rate unit, the currently input flow rate value is compared with a preset flow rate threshold, and if it is detected that the flow rate value exceeds the preset flow rate threshold, a prompt box may pop up on the display screen to prompt the user that the currently input flow rate exceeds the flow rate threshold, and ask the user whether to accept the currently input flow rate, so as to avoid a situation of parameter input error.

For example, if a touch operation of the user on the mode item is received, a mode selection interface as shown in fig. 9E is displayed to receive a mode selection instruction of the user.

Referring back to fig. 9B, the display content of the parameter setting interface further includes infusion operation controls, specifically, an infusion start control and a push control. After receiving the touch operation of the infusion starting control, the infusion pump starts infusion, so that the fluid substance in the infusion tube consumable or the syringe consumable is directionally conveyed to the body of the patient under the driving of the driving device of the infusion pump.

In step S830, after receiving the touch operation on the infusion start control, the infusion pump starts infusion. In the infusion process, an operation interface is provided and displayed on the display screen, the infusion operation control of the operation interface comprises a fast push control and a pause control, and the infusion state of the infusion pump can be changed in response to touch operation on the fast push control or the pause control; when the infusion state of the infusion pump changes, a visual interface corresponding to the infusion state is provided and displayed on the display screen, and the latest infusion state information is displayed through the visual interface. An exemplary operational interface is shown in FIG. 9F. The display content of the operation interface at least comprises infusion parameter information and an infusion operation control. The infusion parameter information includes first infusion parameter information (drug name, flow rate, mode, consumable) and second infusion parameter information (waiting volume/entered volume, time, occlusion pressure) and infusion operation controls (fast push, stop). In the infusion parameter information, only the flow rate item can be edited based on the touch operation.

When a touch operation of the user on the stop (i.e., pause) icon in the running interface is received, the pause interface shown in fig. 9G is entered. The display content of the pause interface comprises infusion state information (pause), first infusion parameter information (drug name, flow rate, mode and consumable), second infusion parameter information (waiting volume, entered volume and time) and infusion operation controls (fast push and start). The first infusion parameter information and the second infusion parameter information can be edited based on touch operation. The second infusion parameter information may be switched based on a touch gesture, for example, if an upward sliding gesture of the user is detected in the second parameter region of the pause interface shown in fig. 9G, the second parameter region may be slid upward, and the blocking pressure information below the time information is displayed, as shown in fig. 9H. In the pause state, if the user performs a dressing change operation or needs to change parameters, the user can jump back to the parameter setting interface. Alternatively, the user may click on the launch control to continue the infusion.

If a touch operation of the user on the fast-pushing control is received under the running or pause interface, the user may jump to a fast-pushing parameter setting interface shown in fig. 9I to set the fast-pushing amount. If a touch operation of the user on the fast-pushing control is received under the interface, jumping to the fast-pushing interface shown in fig. 9J. And under the fast push interface, if the touch operation on the fast push control is received, starting the fast push.

And in the operation process, if an alarm event is detected, controlling to display an alarm interface. And when the alarm interface is displayed, the alarm sound prompt can be controlled to be sent out. Illustratively, the alarm interface may be divided into a low-level alarm interface as shown in fig. 9K and a high-level alarm interface as shown in fig. 9L according to the reason of the alarm. Wherein, the high-level alarm interface can display an alarm graphic, and the low-level alarm interface can not display the alarm graphic. In addition, the low-level alarm interface may not cover the non-core infusion parameter information, and may not enter a pause state even when triggering a low-level alarm, so the low-level alarm interface does not display pause state information, only displays the reason for the alarm, and simultaneously displays an operation control for alarm reset and alarm sound pause. And when receiving the touch operation on the alarm reset icon, returning to the running interface, and when receiving the touch operation on the alarm sound pause control, controlling to pause the alarm sound and simultaneously keeping displaying the alarm interface.

In one embodiment, when the syringe is near empty, an alarm state is entered and an alarm interface is displayed prompting the user that the syringe is near empty, at which time the infusion pump does not enter a pause state. And when the infusion device is completely emptied, entering a pause state while displaying an alarm interface.

In one embodiment, when the syringe is near empty, it is determined whether the infusion pump is in KVO (keep vein open) mode. If the infusion pump is in the KVO mode, the driving device is controlled to drive the liquid medicine to be injected into the patient at a preset speed far lower than the set flow rate until the liquid medicine is completely emptied, so that the time for finishing the injection is prolonged. The visualized interface in KVO mode is shown in fig. 9M. In the KVO mode, infusion state information indicating the KVO state is displayed on the visual interface.

In one embodiment, when a touch instruction of a user to the exhaust control is received, the control driving device moves rapidly to exhaust, and simultaneously displays the visual interface in the exhaust mode, where the visual interface in the exhaust mode is shown in fig. 9N. In the air discharge mode, infusion state information indicating an air discharge state is displayed on a visual interface.

In one embodiment, if the touch operation of the user is not detected within a period of time, the visual interface in the screen locking state as shown in fig. 9O is controlled to be displayed to prevent the occurrence of a false touch. Exemplarily, in a visual interface in a screen locking state, an unlocking control is displayed in an operation area to cover an original operation control; except for the operation area, the display content of other areas is the same as the operation interface or the parameter setting interface, but the user does not enter the editing interface in the screen locking state, namely the user cannot edit the content in the editing interface. And when the touch operation of the user on the unlocking control is received, the screen locking state is released.

In summary, the interface operation method of the infusion pump according to the embodiment of the invention can simplify the infusion operation and improve the user experience.
