In some embodiments, the first flush volume data may be determined based on a first flow rate and a corresponding flush duration.

In some embodiments, the purging process of the interventional pump includes two phases: a priming stage and a flushing stage. At the beginning of flushing the intervention pump, it is necessary to feed flushing liquid into the intervention pump so that the flushing liquid fills the cavity in the intervention pump and the drive conduit, thereby evacuating the air in the cavity in the intervention pump and the air in the drive conduit. At the end of priming, the cavity and the drive conduit in the intervention pump are filled with flushing liquid and air is exhausted, which may belong to the priming phase. During the priming phase, the rinse assembly may be operated in a priming mode of operation to drive the rinse liquid to vent the rinse channel. After the priming is finished, the flushing assembly starts to operate in a flushing working mode, so that the cavity and the driving catheter in the intervention pump are continuously flushed, the intervention pump is used for intervention in a human body, and after the intervention pump is used for intervention in the human body, the flushing assembly can still operate in the flushing working mode, and air is prevented from entering the intervention pump.

Under the design of the flushing process, the pre-filling stage mainly exhausts the pipeline, a part of flushing liquid needs to fill the flushing channel (the flushing pipeline, the cavity and the driving conduit are communicated to form the flushing channel) to exhaust the flushing channel, but no flushing liquid enters the driving conduit during the exhaust, and only gas is discharged from the driving conduit, so that the first flushing amount data can be determined based on the driving information under the condition that the flushing assembly is in the flushing working mode.

Optionally, in case that the flushing assembly is detected to enter the flushing operation mode, the determination of the first flushing amount data based on the above-mentioned first flow is started continuously. I.e. during the flushing phase, flushing liquid continues to enter the intervention pump, partly circulating in the cavity in the intervention pump and the flushing line, partly entering the drive conduit to the pump head for discharge. Therefore, in the flushing stage, the first flow corresponding to the infusion pump can be equivalent to the flushing flow of the flushing liquid entering the driving catheter; after determining the flushing flow of the flushing liquid entering the driving catheter, the corresponding flushing amount information of the flushing liquid entering the driving catheter can be obtained through calculation according to the product of the flushing flow and the flushing time. Therefore, the flushing stage can be determined by judging whether the flushing assembly is in the flushing working mode, so that the time interval for determining the first flushing amount data can be positioned, and the first flushing amount data can be accurately determined.

In other embodiments, the first flush volume data may be detected by other means, the detection principle being as follows: the flushing liquid consumption path of the liquid storage device has two parts, one part is used for filling the flushing channel by exhausting gas, and the other part is used for exhausting from one end of the driving conduit, which is close to the pump head. Thus, the amount of rinse liquid entering the drive conduit may be approximately equal to the total consumption of the reservoir minus the amount of rinse liquid consumed in venting.

Based on this principle, the determining step of the first flushing amount data may include: determining flushing fluid consumption data corresponding to the liquid storage device based on the driving information; acquiring flushing liquid pre-filling data; first rinse volume data is determined based on the rinse volume data and the rinse volume priming data.

The driving information may include a first flow of the infusion pump, and the consumption data of the flushing liquid corresponding to the liquid storage device represents the consumption of the flushing liquid in the liquid storage device under the driving of the infusion pump. The above-described rinse liquid consumption data may be continuously determined based on the first flow rate and the operation time period of the infusion pump, such as the flow rate x time period.

The rinse priming data described above characterizes the volume of rinse liquid consumed to vent the rinse line, cavity, and drive conduit. The rinse liquid priming data may be a preset value determined according to experiments, or may be a value determined according to actual operation, which is not limited in the embodiment of the present application.

One part of the flushing liquid consumption data comprises the flushing liquid volume consumed by exhausting the flushing pipeline, the cavity and the driving conduit, and the other part comprises the first flushing amount data entering the driving conduit. The rinse-off data may thus be subtracted from the rinse-off consumption data to obtain the first rinse-off data. Therefore, the first flushing amount data can be determined according to the flushing liquid consumption data and the flushing liquid prefill data under the condition that the prefill stage and the flushing stage are not distinguished.

In still other embodiments, the first flush volume data may also be detected by detecting when a flush volume enters the drive conduit. Optionally, the above interventional pump comprises a drive catheter handle connected to the drive catheter, the cavity being formed in the drive catheter handle, the drive catheter handle comprising a flushing pressure sensor. Because the drive catheter handle is connected with the drive catheter, the flushing pressure sensor is arranged in the drive catheter handle, the flushing fluid inlet distance between the flushing pressure sensor and the drive catheter is short, the flushing fluid can be considered to enter the setting position of the flushing pressure sensor under the condition that the flushing pressure sensor detects flushing pressure data, the cavity in the drive catheter handle can be filled with the flushing fluid under the condition that the flushing pressure data detected by the flushing pressure sensor accords with the flushing pressure condition corresponding to the flushing state, and the flushing fluid enters the drive catheter, so that the first flushing volume data can be determined based on the driving information under the condition that the flushing pressure data accords with the flushing pressure condition corresponding to the flushing state. The flushing state may refer to a state in a flushing stage, and the flushing pressure condition may be that flushing pressure data is greater than or equal to a flushing pressure threshold value corresponding to the flushing state; accordingly, when the flushing pressure data is detected to be greater than or equal to the flushing pressure threshold corresponding to the flushing state, determining the first flushing volume data according to the first flow. In this way, the first flushing amount data can be determined by detecting the flushing pressure data and determining the start timing of the first flushing amount data without distinguishing the flushing stage from the priming stage and without determining the flushing liquid priming data.

Through the above-mentioned several detection methods, can detect out the volume of the flushing fluid that gets into the drive pipe more accurately under different application scenarios, greatly reduced the flushing volume error that causes when the passageway of flushing pre-fills the exhaust, promote the detection accuracy of first flushing volume data.

In this application embodiment, not only can detect the volume of the flushing fluid that gets into the drive pipe (first flushing volume data), but also can accurately detect the volume of the flushing fluid that gets into the human body through the drive pipe (second flushing volume data) to realize the accurate demonstration of multidimension degree of flushing volume information, be convenient for the doctor to look over and acquire more flushing volume information.

As a method for detecting the second flushing amount data, the following description may be referred to. Since the intervention pump intervention operation is performed at a time after the intervention pump is started, the flushing assembly enters the flushing stage and cannot be equivalent to the intervention pump intervention operation, so that it is necessary to determine whether the intervention pump is in an intervention state and then determine whether to start detecting the second flushing amount data.

In some embodiments, the second flush volume data is determined based on the drive information with the interventional pump in an interventional state.

The intervention state includes a state when the intervention pump is in the target object.

Further, the intervention state includes a pump head in the intervention pump being placed at a position between the left ventricle and the ascending aorta, a blood inlet of the pump head being placed in the left ventricle, and a blood outlet of the pump head being placed in the ascending aorta.

Under the condition that the intervention pump is in an intervention state, determining the flushing flow of flushing liquid entering the target object body based on the first flow corresponding to the infusion pump; after determining the irrigation flow, the volume of irrigation fluid that enters the target object through the drive catheter is calculated from the product of the irrigation flow and the irrigation time period.

Under the condition that the intervention pump is in an intervention state, the calculation of the flushing liquid amount entering the human body is started, and the accuracy of the second flushing liquid amount data detection can be ensured. By independently displaying the volume of the flushing fluid entering the target object body, a user can clearly and accurately know the corresponding flushing volume of the flushing fluid entering the target object body in clinical operation, and can perform the next operation by taking the volume of the flushing fluid entering the target object body as a data basis, thereby providing convenience for the user.

In some embodiments, determining that the intervention pump is in an intervention state comprises: and acquiring the operation information corresponding to the catheter ventricular assist device, and determining whether the intervention pump is in an intervention state by judging the operation information.

The operational information is used to determine that the interventional pump is in an interventional state, or the operational information includes operational information obtained from the device detecting itself via the catheter ventricular assist device.

Optionally, the operation information includes at least one of blood pressure data of the target object and first working state data corresponding to the flushing component, but is not limited thereto, and the embodiment of the present application is not limited thereto specifically.

By utilizing the operation information of the transcatheter ventricular assist device, such as blood pressure data and the working state of the flushing assembly, whether the intervention pump is in an intervention state can be automatically and accurately judged, manual switching is not needed, the efficiency of judging the intervention state is improved, and related sensors are not needed to be additionally arranged.

The first operational status data includes an operational condition of the flushing assembly.

Optionally, the first working state data includes at least one of an operating state of the flushing assembly and a non-operating state of the flushing assembly, but is not limited thereto, and the embodiments of the present application are not limited thereto in particular.

Optionally, the abnormal operating condition comprises at least one of the infusion pump and the circulation pump not operating, or the abnormal operating condition comprises at least one of the infusion pump and the circulation pump operating abnormally due to a mechanical failure.

Illustratively, the manner in which the intervention pump is judged to be in an intervention state includes at least one of the following manners, but is not limited thereto:

judgment is made by blood pressure data. And determining second flushing amount data based on the driving information under the condition that the blood pressure data accords with the blood pressure condition corresponding to the intervention state. The purpose of the intervention state judgment is to determine the start-stop time node for calculating the second flushing volume data, so that the volume of flushing fluid entering the target object can be accurately calculated.

For example, in case the blood pressure data is greater than or equal to a blood pressure threshold value corresponding to the intervention state, the intervention pump is determined to be in the intervention state, and the second flushing amount data is determined based on the driving information. The step of determining the intervention state can be simplified to the greatest extent by determining whether the intervention pump is in the intervention state in the simplest mode through threshold value judgment, and in clinical operation, the determination of the intervention state can be always performed, so that the step is simple and the effect is accurate, which is particularly important for medical equipment with limited calculation power.

Optionally, under the condition that the blood pressure data is greater than or equal to a blood pressure threshold value corresponding to the intervention state, determining that the intervention pump is in the intervention state, and determining the flushing flow of the flushing liquid entering the target object body based on the first flow corresponding to the infusion pump; after determining the flushing flow, a second flushing volume data is calculated from the flushing flow and the flushing time.

For example, in case the blood pressure data does not meet the blood pressure condition corresponding to the intervention state, determining that the intervention pump is not in the intervention state; in the event that the intervention pump is not in an intervention state, determining the second flush volume data is stopped.

Optionally, in the case that the blood pressure data is smaller than the blood pressure threshold corresponding to the intervention state, determining that the intervention pump is not in the intervention state, and stopping determining the second flushing amount data.

Optionally, in case no blood pressure data is detected, it is determined that the interventional pump is not in an interventional state and determining the second flushing amount data is stopped.

The method is characterized in that whether the intervention pump is in an intervention state is directly judged through the acquired blood pressure data, in clinical operation, the intervention part of the intervention pump is conveyed to the body of a target object through the intervention sheath, the intervention sheath is connected with the driving catheter handle after conveying and blood pressure data are measured, and whether the intervention pump is in the intervention state can be determined after the blood pressure data are measured and the corresponding blood pressure conditions are met.

The integrated determination is made by means of the blood pressure data and the first operating state data. And under the condition that the blood pressure data accords with the blood pressure condition corresponding to the intervention state and the first working state data accords with the working condition of the flushing component corresponding to the intervention state, determining second flushing amount data based on the driving information.

For example, under the condition that the blood pressure data is greater than or equal to a blood pressure threshold corresponding to the intervention state and the flushing assembly is normally operated, determining that the intervention pump is in the intervention state, and determining the flushing flow of the flushing fluid entering the target object body based on the first flow corresponding to the infusion pump; after determining the flushing flow, a second flushing volume data is calculated from the product of the flushing flow and the flushing time period.

Optionally, under the condition that the blood pressure data is greater than or equal to a blood pressure threshold value corresponding to the intervention state and the flushing assembly is in normal operation, determining that the intervention pump is in the intervention state, and determining the flushing flow of the flushing fluid entering the target object body based on the first flow corresponding to the infusion pump; after determining the flushing flow, a second flushing volume data is calculated from the product of the flushing flow and the flushing time period.

For example, if the blood pressure data does not meet the blood pressure condition or the first operating state data does not meet the flushing assembly operating condition, determining the second flushing amount data is stopped.

Optionally, in the case that the blood pressure data is smaller than a blood pressure threshold corresponding to the intervention state, or the flushing assembly is not operated, determining that the intervention pump is not in the intervention state, and stopping determining the second flushing amount data.

The two ways of judging whether the intervention pump is in the intervention state are provided, and the other way is to cooperatively judge whether the intervention pump is in the intervention state through the acquired blood pressure data and the first working state data corresponding to the flushing component, and comprehensively judge whether the intervention pump is in the intervention state through the blood pressure data and the first working state data, so that the error rate of the judgment of the intervention state can be greatly reduced, and the accuracy of flushing volume information corresponding to flushing liquid entering the driving catheter is further improved.

In some embodiments, the interventional pump includes a drive catheter handle, a drive catheter, and a pump head; the drive catheter handle comprises a blood pressure sensor and a first pressure measuring interface, the first pressure measuring interface is used for being connected with a second pressure measuring interface of the intervention sheath, the intervention sheath is used for conveying the drive catheter and the pump head, and the blood pressure sensor, the first pressure measuring interface and the second pressure measuring interface are located in a blood pressure measuring channel. In clinical operation, the intervention part of the intervention pump is conveyed to the body of a target object through the intervention sheath, after the intervention sheath is conveyed, the intervention sheath is connected with the driving catheter handle, so that a blood pressure measuring channel can be formed between the intervention sheath and the driving catheter handle, namely, a gap between the intervention sheath and the driving catheter, a pipeline between the intervention sheath and the driving catheter handle and a blood pressure sensor form the blood pressure measuring channel, blood pressure data can be measured, and whether the intervention pump is in an intervention state can be determined after the blood pressure data is measured.

In some embodiments, based on the first flow, the correlation displays rinse amount information corresponding to at least one constituent substance in the rinse solution entering the drive catheter, and/or the correlation displays rinse amount information corresponding to at least one constituent substance in the rinse solution entering the target subject via the drive catheter.

The component materials comprise the components of the flushing liquid. For example, the rinse solution includes glucose, heparin, and physiological saline, but is not limited thereto, and the composition of the rinse solution is not particularly limited in the embodiments of the present application.

The flush volume information corresponding to the constituent substances includes an output volume corresponding to the constituent substances.

In some embodiments, a flush flow of flush fluid into the drive conduit may be determined based on a corresponding first flow of the infusion pump; after determining the flushing flow of the flushing liquid entering the drive catheter, the flushing amount information corresponding to the at least one component substance in the flushing liquid entering the drive catheter is calculated by the flushing flow, the flushing time and the component concentration corresponding to the at least one component substance. Because the flushing liquid can be split after entering the intervention pump, a part of the flushing liquid circulates in the cavity of the intervention pump, and a part of the flushing liquid enters the driving catheter, the flushing amount information corresponding to at least one component substance in the flushing liquid entering the driving catheter can be calculated independently through the method; in addition, the flushing amount information corresponding to the at least one component substance is displayed separately, so that the user can clearly and accurately know the flushing amount corresponding to the at least one component substance of the flushing liquid entering the driving catheter in clinical operation.

In some embodiments, in the case where the interventional pump is in an interventional state, a flushing flow of flushing fluid into the target subject may be determined based on a corresponding first flow of the infusion pump; after the flushing flow is determined, the flushing flow, the flushing time and the component concentration corresponding to the at least one component substance are used for calculating to obtain flushing amount information corresponding to the at least one component substance in the flushing liquid entering the target object. Because the flushing fluid can be split after entering the intervention pump, one part of the flushing fluid circulates in the cavity of the intervention pump, and the other part of the flushing fluid enters the driving catheter, the flushing volume information corresponding to at least one component substance in the flushing fluid entering the target object can be calculated independently through the method; in addition, the flushing amount information corresponding to the at least one component substance is displayed separately, so that the user can clearly and accurately know the flushing amount corresponding to the at least one component substance in the flushing liquid entering the target object in clinical operation.

For example, in the case where the flushing liquid contains a glucose component, in clinical applications, the user can clearly and accurately know the flushing amount of the glucose component into the target object.

For example, as shown in a schematic diagram of the rinse amount information shown in fig. 6, parameters of constituent substances of the rinse solution and the volume of the rinse solution are included in the rinse solution arrangement interface 10, for example, the content of glucose is 5mg, the content of heparin is 5Iu, and the volume of the rinse solution is 200ml, as shown in fig. 6 (a), and the constituent substances in the embodiment of the present application show only glucose and heparin, but are not limited thereto. As shown in fig. 6 (b), in the flushing process, flushing flow rate, flushing pressure, flushing remaining time and flushing amount information 40 are displayed. The flushing amount information 40 includes the current flushing amount and the total flushing amount, and the user can accurately obtain flushing amount information corresponding to at least one component substance in the flushing liquid entering the target object or the drive catheter by viewing the displayed data.

Illustratively, first, the rinse flow rate and the rinse time period are multiplied to obtain a rinse volume of the rinse solution; and multiplying the flushing volume and the ingredient concentration corresponding to the at least one ingredient substance to obtain flushing amount information corresponding to the at least one ingredient substance.

In some embodiments, the flush volume information further includes at least one of a flush remaining time, a current flush volume, and a total flush volume.

The current flushing amount may be a value of the flushing amount of the current start flushing; the total flush volume may refer to the sum of flush volumes corresponding to different flush times. The current flushing volume can also be the accumulated value of the flushing volume after the flushing fluid information is updated last time; the total flushing quantity may also be referred to as the sum of the corresponding flushing quantities during operation.

Optionally, the current flushing volume includes a volume of flushing fluid entering the drive catheter corresponding to the current flushing or a volume of flushing fluid entering the target object through the drive catheter corresponding to the current flushing.

Optionally, the total flush volume comprises a sum of corresponding flushing volumes into the drive catheter during operation or a sum of corresponding volumes of flushing volumes into the target object via the drive catheter during operation. The rinse remaining time may refer to the ratio of the volume of rinse remaining to the current rinse flow.

Optionally, the first rinse volume data includes at least one of a cumulative volume of rinse solution entering the drive conduit during the first period of time, a cumulative volume of rinse solution entering the drive conduit during the second period of time, but is not limited thereto.

Optionally, the second rinse volume data includes at least one of a cumulative volume of rinse solution that enters the target object through the drive catheter during the first period of time, and a cumulative volume of rinse solution that enters the target object through the drive catheter during the second period of time, but is not limited thereto.

The first period may be a period after the last flushing operation, such as a period after the last start of the flushing pump; the period after the latest flushing liquid data configuration operation, for example, the period after the latest new liquid bag information configuration, may also be used.

The above-described second period may be an overall operation period of the control apparatus. The embodiments of the present application are not limited in this regard.

In summary, in the method provided in this embodiment, the driving information corresponding to the flushing component is obtained, where the driving information includes parameter information of the flushing component for driving the flushing fluid; based on the drive information, rinse volume information corresponding to the rinse volume entering the drive conduit is displayed in association. According to the method and the device, the driving information corresponding to the flushing component can be used for independently displaying the flushing quantity information corresponding to the flushing fluid entering the driving catheter, or the flushing quantity information corresponding to the flushing fluid entering the target object body is independently displayed under the condition that the intervention pump is in an intervention state, so that a user can clearly and accurately know the flushing quantity corresponding to the flushing fluid entering the driving catheter or the target object body in clinical operation; in addition, the method for judging whether the two intervention pumps are in the intervention state is also provided, a user can directly judge according to blood pressure data, and can comprehensively judge according to the blood pressure data and the first working state data corresponding to the flushing component, and in clinical operation, the user can flexibly select the judgment mode, so that convenience is improved.

Optionally, in the case of detecting the first flushing amount data and the second flushing amount data, a corresponding alarm or prompt may be performed according to the first flushing amount data and the second flushing amount data. For example, a user may be alerted that some of the material components in the rinse are being used in a lesser or excessive amount.

In order to realize the prompt, the control device can set a flushing amount alarming condition, and the flushing amount prompt information can be output under the condition that the first flushing amount data or the second flushing amount data accords with the flushing amount alarming condition.

The flushing amount alarming conditions comprise a first flushing amount alarming condition corresponding to the first flushing amount data and/or a second flushing amount alarming condition corresponding to the second flushing amount data. The flush volume alarm condition may include the first flush volume data or the second flush volume data being greater than or equal to a corresponding flush volume threshold value or less than a corresponding flush volume threshold value. The setting of the flushing amount alarm condition and the flushing amount threshold value can be set and adjusted according to the actual application scene, and the embodiment of the application is not limited to the setting.

Such cues may be of great importance in clinical applications. For example, the target subject requiring intervention of the pump may have other diseases or symptoms than heart problems, which require control of the amount of related substances in the rinse solution. The concentration of the relevant substances in the flushing liquid is known, and the volume of the flushing liquid entering the target object through the driving catheter can also be detected by the method, so that the accumulated amount of the relevant substances in the flushing liquid entering the target object, namely the flushing amount information corresponding to at least one component substance in the flushing liquid entering the target object, can be determined, and whether the flushing amount corresponding to the at least one component substance entering the human body is within a safety range or not is judged according to the flushing amount alarm condition. For example, the target subject suffers from diabetes and needs to control the amount of glucose entering the human body to be in a safe range, so the second flushing amount alarm condition may include a threshold value of glucose accumulation amount or more, and when the accumulation amount of glucose entering the human body is greater than or equal to the threshold value of glucose accumulation amount, the glucose overdose prompt message is triggered. For another example, the target subject has a blood coagulation requirement, so that the amount of heparin entering the human body needs to be controlled to be in a safe range, and therefore, the second flushing amount alarm condition may include a first heparin accumulation threshold value or more, and the heparin overdose prompt message is triggered when the accumulation of heparin entering the human body is greater than or equal to the first heparin accumulation threshold value. For example, the target subject has an anticoagulation requirement, so that the amount of heparin entering the human body needs to be controlled to be in a safe range, and therefore, the second flushing amount alarm condition may further include a second heparin accumulation threshold value or less, and trigger a heparin too little prompt message when the accumulation of heparin entering the human body is less than or equal to the second heparin accumulation threshold value. The importance and necessity of accurately detecting the second flush volume data can thus also be demonstrated.

The abnormal condition of the relevant flushing amount of the user can be effectively prompted through the prompt information, and the safety of the operation of the interventional pump through the catheter ventricular assist device is improved.

Some of the rinse amount information determined in step 304 above may need to be determined from rinse solution parameter data, such as the rinse amount of the ingredient substance needs to be determined from the concentration of the corresponding ingredient substance in the rinse solution and the rinse amount of the rinse solution, such as the rinse amount of the ingredient substance = concentration of the ingredient substance x the rinse amount of the rinse solution.

Optionally, the input of the flushing fluid parameter data can be realized by sequentially inputting parameters such as constituent components, component concentration and the like of the flushing fluid; or, the input of the flushing fluid parameter data can realize quick input through inputting the flushing fluid number or the flushing fluid name of the flushing fluid, but is not limited to the quick input.

For example, the input of the parameter data of the flushing liquid can be realized by sequentially inputting the constituent components of the flushing liquid, such as glucose and heparin, respectively inputting the respective corresponding contents or component concentrations in the parameter frames corresponding to the glucose and the heparin, and simultaneously inputting the volume of the flushing liquid.

For example, in the case of a standard configuration of the rinse solution, the entry of the rinse solution information may also be accomplished by entering a rinse solution number or a rinse solution name of the rinse solution.

Optionally, the rinse solution parameter data includes at least one of preset rinse solution parameter data and entered rinse solution parameter data, but is not limited thereto, and the embodiment of the present application is not limited thereto in particular.

The preset flushing fluid parameter data comprise data recorded in advance or flushing fluid parameter data recorded last time, and can be directly called in the quick recording operation of the flushing fluid data.

In some embodiments, a rinse solution configuration interface is displayed, responsive to entry of rinse solution parameter data, to obtain rinse solution parameter data.

In some embodiments, a rinse solution configuration interface is displayed, responsive to a quick entry of rinse solution parameter data, to obtain rinse solution parameter data.

For example, the rinse solution parameters include a concentration parameter, a quality parameter and a rinse solution volume parameter corresponding to the rinse solution substance, each set of combined data includes parameter data corresponding to each parameter, the combined data may be parameter data preset for each parameter, commonly used parameter data may be selected as the parameter data, for example, a glucose concentration in the rinse solution is generally 5%, a rinse solution volume is generally 500ml, and then a value corresponding to the glucose concentration in a certain combined data may be 5%, and a value corresponding to the rinse solution volume may be 500ml. The above-mentioned at least one set of combination data is mainly for enabling the user to rapidly configure each parameter of the rinse solution, so that the rinse solution parameter data is not required to be configured by using a keyboard in a conventional manner, the complexity of configuration operation is reduced, the rinse solution configuration time is shortened, and the reduction of the configuration complexity and the shortening of the configuration time are critical for critical clinical situations.

The user can select the combination data matched with the flushing fluid parameters of the liquid storage device which is currently ready to be replaced from at least one group of combination data, and trigger the application operation aiming at the combination data, so that the flushing fluid parameter data can be rapidly configured. Specifically, the apparatus determines the target combination data as the above-described rinse liquid parameter data in response to an application operation for the target combination data; wherein the target combination data is a selected one of the at least one set of combination data, and the rinse data configuration operation includes an application operation.

Alternatively, the application operation may be received through an application control corresponding to the combined data. The application control may be an application option displayed in the rinse solution configuration interface, or may be an entity key on the control device, which is not limited in this embodiment of the present application.

Under the condition that the control equipment presets a plurality of groups of combination data, the flushing liquid configuration interface can comprise switching controls corresponding to the groups of combination data. Similar to the application control, the switch control may be a switch option displayed in the rinse solution configuration interface, or may be an entity button on the control device, which is not limited in this embodiment of the present application. The user can check the data information of a certain group of combined data by operating the corresponding switching control, so as to judge whether the group of combined data is to be applied. The control device displays the target combination data in response to a selection operation for the target switching control.

Taking the example of the flushing fluid data configuration operation through interface triggering, a flushing fluid configuration interface is displayed, and an input control is displayed on the flushing fluid configuration interface. The input control is used for inputting flushing fluid parameter data of flushing fluid.

Optionally, the display manner of the rinse solution configuration interface is at least one of the following manners, but is not limited thereto:

the rinse solution configuration interface is displayed on the user interface instead, i.e., the rinse solution configuration interface overlays the user interface;

the rinse solution deployment interface and the user interface are displayed simultaneously in a side-by-side fashion.

As shown in the schematic diagram of the user interface shown in fig. 8, before the rinse solution is rinsed, rinse solution parameter data needs to be input, a rinse control 701 is displayed at the bottom of the user interface, the rinse control 701 is identified as "two water drops", and by triggering the rinse control 701, the rinse control enters the rinse interface. And responding to the corresponding flushing liquid data configuration operation of the liquid storage device, such as clicking a new liquid bag button, and displaying a flushing liquid configuration interface.

As shown in the schematic diagram of the rinse solution configuration interface in fig. 9, after the rinse solution control 805 is triggered, the rinse solution configuration interface 801 is displayed with an input control 802, and rinse solution parameter data 803 of the rinse solution can be input by the triggering operation of the input control 802. After the input of the rinse fluid parameter data 803 is completed, if the entered rinse fluid parameter data 803 is not satisfactory, for example, an out-of-range or a value of 0 exists, a further prompt is made and the entered rinse fluid parameter data 803 cannot be saved; if the entered rinse fluid parameter data 803 meets the requirements and a confirm save instruction is received, such as clicking the ok button 804, the current rinse fluid parameter data 803 is updated and saved.

Optionally, the operation of triggering the flushing control includes at least one of clicking, double clicking, triple clicking, long clicking, and sliding, but is not limited thereto, and the embodiments of the present application are not limited thereto in particular.

Step 604: and under the condition that the flushing fluid parameter data does not accord with the preset parameter range condition, limiting and storing the flushing fluid parameter data.

In the process of inputting the flushing fluid parameter data, the flushing fluid parameter data is limited to be stored under the condition that the flushing fluid parameter data does not accord with the preset parameter range condition.

The preset parameter range condition includes a preset parameter range. For example, the preset parameter range of the concentration value is 1% -50%, and if 75% is input, the data is forbidden to be stored.

The preset parameter range conditions include at least one of whether the numerical value of the parameter is out of range and whether the parameter is 0, but are not limited thereto, and the embodiment of the present application is not limited thereto in particular.

When the flushing fluid parameter data of the new flushing fluid is input, detecting whether the input flushing fluid parameter data meets the preset parameter range conditions, and storing the flushing fluid parameter data when the input flushing fluid parameter data meets the preset parameter range conditions; in the case that the entered rinse fluid parameter data does not meet the preset parameter range conditions, for example, an out-of-range or a value of 0 exists, the storage of the rinse fluid parameter data is limited.

By limiting the way of storing the out-of-range data, the user can be prompted to replace the correct and effective liquid bag (liquid bag error) under one condition, so that the accuracy of detecting the flushing amount information is ensured.

In some embodiments, a replenishment notice is displayed in response to a remaining volume of rinse solution corresponding to the reservoir device being less than a remaining volume threshold.

The fluid replacement prompt message is used for prompting that the parameter data of the new flushing fluid needs to be recorded.

Optionally, the fluid replacement prompt message is a prompt message, or the fluid replacement prompt message provides a parameter configuration inlet of the flushing fluid.

The flushing fluid parameter configuration inlet is used for triggering the control device to enter a flushing fluid parameter configuration state.

The manner of providing the rinse liquid parameter configuration inlet by the fluid replacement prompt message includes at least one of the following manners, but is not limited thereto:

and (3) taking an information frame where the fluid replacement prompt information is positioned as a flushing fluid parameter to configure an inlet control. The parameter configuration state of the flushing fluid can be directly entered by triggering any position of an information frame where the fluid replacement prompt information is located;

and additionally displaying flushing fluid parameters to configure an inlet control on the fluid replacement prompt information. The flushing fluid parameter configuration state can be entered by triggering the flushing fluid parameter configuration inlet control on the fluid replacement prompt message.

Optionally, the rinse liquid data configuration operation includes at least one of, but is not limited to:

entering rinse liquid parameters in an input box through a touch screen or a keyboard;

displaying an input box and a knob control, and turning the knob control to increase/decrease flushing fluid parameters so as to realize the entry of the flushing fluid parameters;

displaying an input box and a digital adjustment control, and adjusting the flushing fluid parameters by adjusting a "+" - "control in the digital adjustment control so as to realize the entry of the flushing fluid parameters.

The control equipment can receive the flushing fluid data configuration operation under the flushing fluid parameter configuration state so as to update the flushing fluid information corresponding to the liquid storage device.

According to the method provided by the embodiment, under the condition that the surplus of the flushing liquid corresponding to the liquid storage device is smaller than the surplus threshold, the liquid supplementing prompt information is displayed and used for reminding a user of timely adding new flushing liquid information, meanwhile, the liquid supplementing prompt information provides a flushing liquid parameter configuration inlet, the flushing liquid parameter configuration inlet can be provided for quickly entering a flushing liquid parameter configuration state, so that flushing liquid data configuration operation is more convenient and quick, and operation efficiency is improved.

As shown in the schematic diagram of the fluid replacement prompt message in fig. 10, when the remaining amount of the rinse solution is less than the remaining amount threshold, the fluid replacement prompt message 901 is displayed in the form of a floating window in the user interface, and the fluid replacement prompt message 901 includes a prompt that "the remaining amount of the rinse solution is less than the remaining amount threshold" and a rinse solution parameter configuration inlet 902, and the rinse solution configuration interface can be accessed by providing the rinse solution parameter configuration inlet 902. In addition, after the rinse solution parameter configuration entry 902 is triggered, the input data is not opposite to or has a value of 0, the rinse solution configuration interface is always displayed and cannot exit unless the cancel control is triggered or after a preset time, the rinse solution configuration interface automatically exits, but the rinse solution information corresponding to the original rinse solution is retained. For example, the volume of rinse solution is 200ml, and in the case of 180ml of rinse solution, a refill prompt message 901 is displayed in the form of a floating window in the user interface, thereby reminding the user to refill the rinse solution.

In addition, there may be cases where the rinse liquid data is configured incorrectly, such as when the entered rinse liquid parameter data does not match the actual rinse liquid parameter of the liquid storage device, so that a function of modifying the rinse liquid parameter is provided in the control device. Optionally, the control device updates the rinse liquid parameter data in response to a rinse liquid data modification operation corresponding to the liquid storage device. Specifically, in one possible implementation manner, the rinse solution configuration interface includes a rinse solution parameter modification inlet, the control device may receive the rinse solution data modification operation based on the rinse solution parameter modification inlet, for example, select a corresponding parameter through a parameter selection operation, configure the correct rinse solution parameter data for the parameter through a numeric keyboard operation, and store the modified rinse solution parameter data in response to a confirmation instruction, so as to update the rinse solution parameter data.

In some examples, the fluid storage device is a fluid bag, which may be replaceable. And under the condition that the parameter configuration of the current liquid bag is wrong, the parameter modification operation of the flushing liquid aiming at the current liquid bag can be received, and the parameter data of the current liquid bag is updated. In the case of a parameter configuration error of the historical fluid bag, a rinse fluid parameter modification operation for the historical fluid bag may be received, and parameter data of the historical fluid bag may be updated.

The rinse amount information may be determined based on the rinse solution parameter data, and thus after the rinse solution parameter data is updated, the rinse amount information needs to be updated based on the updated rinse solution parameter data. Optionally, the control device may update the flushing amount information based on the parameter data after the current liquid bag update, and may also update the flushing amount information according to the parameter data after the historical liquid bag update.

In some examples, after modifying the rinse fluid parameter data (e.g., modifying the parameter data of the fluid bag), the consumption of rinse fluid may not need to be redetermined, and the parameters that need to be calculated by the rinse include at least one of the following: flushing volume information corresponding to at least one component substance and flushing liquid allowance corresponding to a liquid storage device.

In case that the concentration of at least one of the constituent substances is updated, the flushing amount information, such as the quality, corresponding to the respective constituent substance is updated, and a re-determination is required. For example, the updated rinse amount corresponding to the updated component material=updated concentration×rinse amount.

In the case of an update of the corresponding flushing-liquid volume of the liquid-storage device, the flushing-liquid residual quantity, for example, flushing-liquid residual quantity=updated flushing-liquid volume-flushing-liquid quantity, is updated.

Optionally, in the event that the above-described irrigant parameter data is not obtained, activation of the transcatheter ventricular assist device is restricted. For example, the activation of the flushing pump, the intervention pump is prohibited.

In the operation process of the intervention pump, the intervention pump needs to be continuously flushed by using flushing liquid, so that parameter data of the flushing liquid needs to be accurately determined, various dosage information and residual information of the flushing liquid can be accurately detected, if the flushing liquid parameter data are not configured, the flushing pump is started, a part of flushing liquid information is not recorded, and the condition that the flushing liquid information is actually used but not recorded is caused, so that the detection of the flushing amount information is error, and the use risk is brought, such as pumping air into the intervention pump after the flushing liquid is used, which is forbidden. Through the limiting rule, the error can be effectively avoided. Furthermore, the method is helpful for prompting the user to install and configure the parameter data of the flushing liquid before starting the flushing pump or the intervention pump, preventing wrong operation and ensuring the safety of a target object such as a patient.

In summary, according to the method provided in the embodiment, the rinse liquid parameter data is obtained through the rinse liquid data configuration operation, and the input data is checked, so that the input of erroneous data is avoided. According to the method and the device, whether the input flushing fluid parameter data meet the preset parameter range conditions is checked, so that the input of error data is avoided, and the input efficiency is improved.
