Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a method and apparatus for detecting flushing information in a transcatheter ventricular assist device. Background Technology

[0002] The working principle of an interventional artificial heart is as follows: the interventional pump is delivered to the left ventricle via the femoral artery. The inlet is located in the left ventricular outflow tract, and the outlet is located in the aorta. When the interventional pump is running, it can draw blood out from the inlet at the left ventricular end and then return it to the aorta through the outlet at the aortic end, thus achieving the function of cardiac assistance.

[0003] In related technologies, when purging the interventional pump, a prepared flushing solution is introduced into the interventional pump. The flushing solution occupies the gap in the interventional pump, thereby achieving air venting.

[0004] However, in related technologies, the control of the flushing volume of the flushing fluid relies entirely on the operator's experience, which is difficult to quantify and determine, and it is difficult to ensure the accuracy of the flushing volume. Therefore, how to ensure the accuracy of the flushing volume is an important problem that urgently needs to be solved. Summary of the Invention

[0055] A ventricular assist device is a mechanical circulatory assist device that replaces the work of the ventricles, including but not limited to external ventricular assist devices, transcatheter ventricular assist devices, and implantable ventricular assist devices.

[0056] A transcatheter ventricular assist device (TAAVD), including a TAVD control unit (hereinafter referred to as the control device) and a TAVD interventional pump (hereinafter referred to as the interventional pump) used in conjunction with it, is an interventional blood pump suitable for providing temporary left ventricular circulation support during relevant procedures.

[0057] Interventional pump: In medical settings, this refers to an interventional pump used to assist the heart in providing the power for blood circulation. Optionally, the interventional pump is a cardiac pump that is inserted into a living organism. Optionally, some or all components of the interventional pump are inserted into a living organism.

[0058] Figure 1 A schematic diagram illustrating an application scenario of an interventional pump according to an embodiment of this application is shown. The interventional pump includes a drive catheter handle (not shown), a catheter 102, and a pump head 103. A drive motor 101 is coupled to the proximal end of the catheter 102 via the drive catheter handle, and the pump head 103 is connected to the distal end of the catheter 102.

[0059] The pump head 103 in the interventional pump can be percutaneously inserted into the heart through the peripheral blood vessels via the catheter 102. The pump head 103 is placed between the left ventricle and the ascending aorta. The blood inlet of the pump head 103 is placed into the left ventricle, and the blood outlet of the pump head 103 is placed into the ascending aorta. The drive motor can be connected to the interventional pump to drive the impeller in the pump head to rotate, thereby pumping blood from the left ventricle into the ascending aorta to achieve ventricular assist function.

[0060] Figure 2 A schematic diagram of a transcatheter ventricular assist device provided in another exemplary embodiment of this application is shown. The transcatheter ventricular assist device includes at least a control device 130, an interventional pump 120, a flushing assembly, and a flushing tubing 110. The control device 130 includes at least a console 131 and a drive motor 132. The flushing assembly includes an infusion pump 151 and a circulation pump 152. Clinical medical personnel can monitor the system status and patient physiological parameters on the control host interface, and provide different levels of ventricular assist by adjusting the rotation speed of the interventional pump 120 according to the patient's needs, thereby temporarily maintaining blood circulation to the patient's vital organs and relieving the burden on the heart.

[0061] The interventional pump system includes interventional pump 120 and delivery system (not shown in the figure).

[0062] The interventional pump 120 includes a pump head 123 (containing an impeller, a support, and a diaphragm), a drive catheter 122, a drive catheter handle 121 (containing a drive catheter locking connector), a flushing pressure sensor, and a drive catheter flushing tubing connector. The interventional pump 120 can be percutaneously inserted into the heart via a peripheral blood vessel. The pump head 123 is placed between the left ventricle and the ascending aorta. The blood inlet of the pump head 123 is placed in the left ventricle, and the blood outlet of the pump head 123 is placed in the ascending aorta. A drive motor 132 can be connected to the interventional pump to drive the impeller in the pump head 123 to rotate, thereby pumping blood from the left ventricle into the ascending aorta to achieve ventricular assist function.

[0063] The delivery system includes a dilator, an interventional sheath, and a delivery device. The system dilates the blood vessel and provides access for the interventional pump to be inserted into the heart; the delivery device and interventional sheath function to retract the pump head. The delivery device and dilator are removed after the interventional pump is in place. The interventional sheath remains in the patient's blood vessel until the interventional pump is removed.

[0064] The flushing pipeline 110 includes at least the above-mentioned supplementary pipeline, connecting structure, flushing fluid inlet pipe and flushing fluid outlet pipe.

[0065] The infusion pump 151 can be connected to the flushing line 110. The infusion pump 151 realizes the function of flushing fluid delivery and control by squeezing the flushing line, thereby preventing blood from entering the drive catheter 122 of the interventional pump and causing thrombosis.

[0066] The infusion pump 151 drives the flushing pump tube on the flushing tubing flushing kit, which can pump the flushing fluid in the storage device 140 connected to the flushing tube into the cavity inside the interventional pump through the flushing tubing, thereby preventing blood from entering the interventional pump drive catheter 122.

[0067] Figure 3 This is a flowchart illustrating an exemplary embodiment of a method for detecting flushing information in a transcatheter ventricular assist device (TAVED). The method is applied to a TAVED. The method includes:

[0068] Step 302: Obtain the driving information corresponding to the flushing component.

[0069] Transcatheter ventricular assist devices include control equipment, interventional pump, flushing assembly, and flushing tubing. For example... Figure 2 As shown, the control device 130 is used to control the operation of the flushing assembly, and thus control the flushing flow rate corresponding to the flushing assembly. One end of the flushing line 110 is connected to the reservoir 140, and the other end of the flushing line 110 is connected to the interventional pump 120. The flushing assembly is used to pump the flushing fluid in the reservoir 140 into the interventional pump 120 through the flushing line 110. The flushing fluid is used to flush the cavity and drive conduit 122 in the interventional pump 120. The flushing line forms a flushing passage between the reservoir 140 and the interventional pump 120, facilitating the pumping of flushing fluid into the interventional pump 120 through the flushing line 110.

[0070] Optionally, the liquid storage device 140 may be at least one of a liquid storage bag or a liquid storage bottle, but is not limited thereto, and the embodiments of this application do not specifically limit it.

[0071] Rinsing fluid can refer to a liquid used for cleaning or a liquid used for purging air.

[0072] In some embodiments, during the flushing process, the control device 130 controls the flushing assembly to operate. The flushing assembly pumps the flushing fluid in the storage device 140 into the interventional pump 120 through the flushing pipeline 110. After entering the interventional pump, the flushing fluid will be diverted. The diversion means that part of the flushing fluid pumped into the interventional pump 120 flows into the cavity in the interventional pump and flows back to the flushing pipeline to form a circulation, while part enters the drive conduit and is discharged from the pump head 123.

[0073] Optionally, the components of the flushing solution may include at least one of glucose, heparin, and physiological saline, but are not limited thereto. The embodiments of this application do not specifically limit the components of the flushing solution.

[0074] The driving information includes parameter information for the flushing components that drive the flushing fluid.

[0075] Optionally, the driving information may include at least one of the flushing flow rate and the rotational speed of the flushing components, but is not limited thereto, and the embodiments of this application do not specifically limit this.

[0076] Flushing flow rate can refer to the volume of flushing fluid flowing through the flushing pipeline per unit time.

[0077] Optionally, the flushing assembly is used to squeeze the tubing to pump flushing fluid to achieve flushing. For example, the flushing assembly can employ a peristaltic pump, which pumps flushing fluid by alternately squeezing and releasing the flushing fluid delivery tubing.

[0078] Step 304: Based on the driving information, display the flushing volume information corresponding to the flushing fluid entering the driving conduit.

[0079] Flushing volume information is used to characterize the amount of flushing fluid consumed through the drive conduit.

[0080] In some embodiments, the flushing volume information includes the amount of flushing fluid entering the drive conduit.

[0081] For example, when the intervention pump is not in an interventional state, the flushing volume information includes the amount of flushing fluid entering the drive catheter.

[0082] In some embodiments, the flushing volume information includes the amount of flushing fluid that enters the target body via the drive conduit.

[0083] For example, when the interventional pump is in the interventional state, the flushing volume information includes at least one of the following: the amount of flushing fluid entering the drive catheter and the amount of flushing fluid entering the target body through the drive catheter.

[0084] The drive conduit is used to pass through the drive shaft that drives the impeller to rotate, thereby pumping blood. There is a gap between the drive conduit and the drive shaft, and the drive shaft rotates inside the drive conduit. Therefore, flushing fluid is needed to flush and wet the gap and prevent air from entering the gap.

[0085] For example, based on the driving information of the flushing component, the flushing volume information corresponding to the flushing fluid entering the driving conduit can be calculated.

[0086] Based on the driving information of the flushing component, the flushing flow rate of the flushing fluid entering the driving conduit can be determined. The flushing volume of the flushing fluid entering the driving conduit can be calculated using the flushing flow rate and flushing duration.

[0087] For example, based on the driving information corresponding to the driving component, the flushing flow rate of the flushing fluid entering the driving conduit can be determined, and the flushing volume information of the flushing fluid entering the driving conduit can be calculated by multiplying the flushing flow rate and the flushing duration.

[0088] In some embodiments, based on the drive information corresponding to the infusion pump and / or the drive information corresponding to the circulation pump in the flushing assembly, flushing volume information corresponding to the flushing fluid entering the drive conduit is displayed in association.

[0089] For example, the drive information corresponding to the circulation pump includes the second flow rate corresponding to the circulation pump; based on the second flow rate, the flushing volume information is displayed in association.

[0090] For example, the driving information includes a third flow rate corresponding to the flushing fluid entering the interventional pump; obtaining the shunt information between the cavity in the interventional pump and the driving catheter; calculating the flushing flow rate of the flushing fluid entering the driving catheter based on the shunt information and the third flow rate; and calculating the flushing volume information of the flushing fluid entering the driving catheter based on the flushing flow rate and flushing duration.

[0091] In some embodiments, the third flow is equal to the second flow; or, the third flow is equal to the first flow; or, the third flow is determined based on the first flow and the second flow.

[0092] The diversion information includes the diversion ratio of the flushing fluid between the cavity of the interventional pump and the drive conduit. Since the structures of the cavity and drive conduit in the interventional pump are relatively fixed, the diversion ratio of the flushing fluid between these two components is relatively stable. The total flushing flow rate of the flushing fluid entering the interventional pump (e.g., the flushing flow rate of the circulation pump) can be obtained, and the diversion ratio of the flushing fluid between the cavity of the interventional pump and the drive conduit can be determined based on at least one of the circulation pump's rotational speed and the flushing fluid's pressure.

[0093] For example, diversion information is determined based on at least one of the rotational speed of the circulating pump and the pressure value of the flushing fluid.

[0094] Optionally, the flow split ratio is related to at least one of the circulating pump speed and the flushing fluid pressure. The determination of the relationship between the flow split ratio and at least one of the circulating pump speed and flushing fluid pressure is based on historical experiments.

[0095] In summary, the method provided in this embodiment obtains the driving information corresponding to the flushing component, which includes parameter information of the flushing component driving the flushing fluid; based on the driving information, it displays the flushing volume information corresponding to the flushing fluid entering the driving catheter. This application can display the flushing volume information corresponding to the flushing fluid entering the driving catheter separately using the driving information corresponding to the flushing component. Since the flushing fluid is split after entering the interventional pump, with part circulating in the cavity of the interventional pump and part entering the driving catheter, the flushing volume corresponding to the flushing fluid entering the driving catheter can be calculated separately using the above method; this allows users to clearly and accurately know the flushing volume information corresponding to the flushing fluid entering the driving catheter during clinical operations.

[0096] Figure 4 This is a flowchart illustrating an exemplary embodiment of a method for detecting flushing information in a transcatheter ventricular assist device (TAVED). The method is applied to a TAVED. The method includes:

[0097] Step 402: Obtain the driving information corresponding to the flushing component.

[0098] Transcatheter ventricular assist devices include control equipment, interventional pump, flushing assembly, and flushing tubing. For example... Figure 2 As shown, the control device 130 is used to control the operation of the flushing assembly, and thus control the flushing flow rate corresponding to the flushing assembly. One end of the flushing pipeline 110 is connected to the storage device 140, and the other end of the flushing pipeline 110 is connected to the interventional pump 120. The flushing assembly is used to pump the flushing fluid in the storage device 140 into the interventional pump 120 through the flushing pipeline 110. The flushing fluid is used to flush the cavity and drive conduit 122 in the interventional pump 120.

[0099] Optionally, the flushing assembly includes an infusion pump 151 and a circulation pump 152.

[0100] The infusion pump 151 is used to pump the flushing fluid in the storage device 140 into the flushing line 110, and the flushing line 110 forms a circulation channel with the cavity.

[0101] The circulation pump 152 is used to pump the flushing fluid in the flushing line 110 into the intervention pump 120 to circulate and flush the cavity and the drive conduit 122.

[0102] In some embodiments, during the flushing process, the control device 130 controls the flushing assembly to operate, and the infusion pump 151 pumps the flushing fluid in the storage device 140 into the interventional pump 120 through the flushing pipeline 110. After entering the interventional pump, the flushing fluid will be diverted. The circulation pump 152 causes a portion of the flushing fluid to circulate and flush the cavity in the interventional pump, while the other portion of the flushing fluid enters the drive conduit to flush the drive conduit and is discharged from the pump head 123.

[0103] For example, such as Figure 5 The diagram shows a schematic of a transcatheter ventricular assist device during the flushing phase provided in an exemplary embodiment of this application.

[0104] During the flushing phase, the first valve port 231 and the second valve port 221 are connected. The flushing assembly 210 includes an infusion pump 211 and a circulation pump 212. The infusion pump 211 is used to deliver flushing fluid to the cavity of the interventional pump 240 via the second flushing passage during the flushing phase, and the circulation pump 212 is used to control the circulation of flushing fluid to flush the cavity of the interventional pump 240 during the flushing phase.

[0105] The flushing pipeline includes at least a replenishment pipeline L1 connected to the flushing fluid container 250. The replenishment pipeline L1 is connected to the flushing fluid inlet pipe L2 and the flushing fluid outlet pipe L3 via a connecting structure. The flushing fluid inlet pipe L2 is connected to the first valve port 231; the flushing fluid outlet pipe L3 is connected to the second valve port 221. The flushing fluid inlet pipe L2, the cavity of the interventional pump, and the flushing fluid outlet pipe L3 form a circulating flushing loop, in which the flushing fluid circulates and flushes to cool the internal cavity of the interventional pump. In this structure, the replenishment pipeline L1, via the connecting structure, and the flushing fluid outlet pipe L3 form the first flushing passage, and the replenishment pipeline L1, via the connecting structure, and the flushing fluid inlet pipe L2 form the second flushing passage. Optionally, the replenishment pipeline L1, the connecting structure, the flushing fluid inlet pipe L2, and the flushing fluid outlet pipe L3 can be integrally formed pipelines or assembled pipelines.

[0106] The infusion pump 211 is located in the common part of the first flushing passage and the second flushing passage at the starting position. The common part can refer to the junction of the first flushing passage and the second flushing passage at the starting position, such as the supplementary pipeline L1 mentioned above. The circulation pump 212 is located in the passage of the second flushing passage that is not shared with the first flushing passage. The location of the passage that is not shared with the first flushing passage can refer to the location of the second flushing passage excluding the junction of the starting position, such as the flushing fluid inlet pipes L2 and / or L3 mentioned above. The number of circulation pumps is not limited in this embodiment. Figure 5 The interventional pump 240 is also shown to include a drive catheter handle 241, a drive catheter 242, and a pump head 243.

[0107] Under the pumping action of infusion pump 211 and circulation pump 212, the flushing fluid in the storage device 250 is delivered to the second flushing passage and injected into the inner cavity of the drive catheter handle 241, and then circulates to the first flushing passage. The flushing fluid that has passed through the first flushing passage will flow back into the second flushing passage. In addition, a portion of the flushing fluid flowing into the cavity of the drive catheter handle 241 will flow into the drive catheter 242 of the intervention pump 240 and be discharged at the pump head 243.

[0108] Rinsing fluids include liquids used for cleaning or liquids used for purging air.

[0109] The driving information includes parameter information for the flushing components that drive the flushing fluid.

[0110] For example, the driving information includes a first flow rate corresponding to the infusion pump.

[0111] The first flow rate includes the volume of flushing fluid flowing through the infusion pump per unit time. The infusion pump is used to squeeze the tubing to pump the flushing fluid to achieve flushing. For example, the infusion pump can be a peristaltic pump, which pumps the flushing fluid by alternately squeezing and releasing the flushing fluid delivery tubing.

[0112] For example, the first flow rate can be determined by calculating the first flow rate using the rotational speed of the infusion pump and the rotational diameter of the pressure roller of the flushing drive component.

[0113] Step 404: Based on the first flow rate, display the associated flushing volume information.

[0114] Flushing volume information is used to characterize the amount of flushing fluid entering the drive catheter and / or the amount of flushing fluid entering the target body via the drive catheter.

[0115] For example, based on the first flow rate corresponding to the infusion pump, the flushing flow rate of the flushing fluid entering the drive conduit can be determined. After determining the flushing flow rate of the flushing fluid entering the drive conduit, the flushing volume information corresponding to the flushing fluid entering the drive conduit can be calculated using this flushing flow rate and the flushing duration. During the flushing process, since the flushing fluid through the drive conduit flows out from the pump head as output, and the flushing fluid in the storage device is pumped into the drive conduit as input by the infusion pump, the first flow rate corresponding to the infusion pump can be approximated as the flushing flow rate of the flushing fluid entering the drive conduit. Therefore, the flushing volume information corresponding to the flushing fluid entering the drive conduit can be calculated using this flushing flow rate and the flushing duration, ensuring the accuracy of the flushing volume information detection.

[0116] Optionally, the flushing volume information includes at least one of the first flushing volume data and the second flushing volume data, but is not limited thereto, and the embodiments of this application do not specifically limit this.

[0117] The first flushing volume data represents the amount of flushing fluid entering the drive catheter. The second flushing volume data represents the amount of flushing fluid entering the target body through the drive catheter, or the second flushing volume data is the cumulative total amount of flushing fluid entering the target body through the drive catheter.

[0118] Optionally, the first flushing volume data includes the amount of flushing fluid entering the drive conduit during flushing. Optionally, the first flushing volume data includes the sum of the amount of flushing fluid flowing out of the drive conduit and the amount of flushing fluid remaining in the drive conduit.

[0119] Regarding the detection of the aforementioned first flushing volume data, any of the following implementation methods can be selected based on the actual situation.

[0120] In some embodiments, the first flushing volume data described above can be determined based on the first flow rate and the corresponding flushing duration.

[0121] In some embodiments, the flushing process of the interventional pump includes two phases: a pre-filling phase and a flushing phase. When flushing the interventional pump begins, flushing fluid is delivered into the pump to fill the cavities and drive conduits, thereby expelling air from these areas. At the end of the pre-filling phase, the cavities and drive conduits are filled with flushing fluid, and the air has been expelled; this process can be considered part of the pre-filling phase. During the pre-filling phase, the flushing assembly can operate in pre-filling mode, driving the flushing fluid to vent air from the flushing channels. After pre-filling, the flushing assembly begins operating in flushing mode, continuously flushing the cavities and drive conduits of the interventional pump while awaiting interventional pump insertion into the human body. Even after interventional pump insertion, the flushing assembly can continue operating in flushing mode to prevent air from entering the pump.

[0122] Under the above flushing process design, the pre-filling stage is mainly to vent the pipeline. A portion of the flushing fluid needs to fill the flushing channel (the flushing pipeline, cavity, and drive conduit are connected to form the flushing channel) to vent the flushing channel. However, no flushing fluid enters the drive conduit during venting; only gas is discharged from the drive conduit. Therefore, the first flushing volume data can be determined based on the above drive information when the flushing component is in the flushing working mode.

[0123] Optionally, upon detecting that the flushing assembly has entered the flushing operating mode, the first flushing volume data is continuously determined based on the aforementioned first flow rate. That is, during the flushing phase, the flushing fluid continuously enters the interventional pump; a portion circulates within the cavity of the interventional pump and the flushing tubing, while a portion enters the drive conduit and is discharged through the pump head. Therefore, during the flushing phase, the first flow rate corresponding to the infusion pump can be equivalent to the flushing flow rate of the flushing fluid entering the drive conduit. After determining the flushing flow rate of the flushing fluid entering the drive conduit, the flushing volume information corresponding to the flushing fluid entering the drive conduit can be calculated by multiplying this flushing flow rate by the flushing duration. Thus, by determining whether the flushing assembly is in the flushing operating mode, the flushing phase can be determined, thereby enabling the location of the time interval for determining the first flushing volume data, and consequently, accurate determination of the aforementioned first flushing volume data.

[0124] In other embodiments, the first flushing volume data can be detected in a different way. The detection principle is as follows: the flushing fluid in the storage device is consumed in two ways: one is to fill the flushing channel for venting, and the other is to be discharged from the end of the drive conduit near the pump head. Therefore, the amount of flushing fluid entering the drive conduit can be approximately equal to the total consumption of the storage device minus the amount of flushing fluid consumed during venting.

[0125] Based on this principle, the steps for determining the first flushing volume data may include: determining the flushing fluid consumption data corresponding to the storage device based on the driving information; obtaining flushing fluid pre-charge data; and determining the first flushing volume data based on the flushing fluid consumption data and the flushing fluid pre-charge data.

[0126] The driving information may include the first flow rate of the infusion pump, and the flushing fluid consumption data corresponding to the storage device represents the amount of flushing fluid consumed in the storage device under the drive of the infusion pump. Based on the first flow rate and the running time of the infusion pump, such as flow rate × time, the flushing fluid consumption data can be continuously determined.

[0127] The aforementioned flushing fluid pre-charge data characterizes the volume of flushing fluid required to vent the flushing pipeline, cavity, and drive conduit. This flushing fluid pre-charge data can be a preset value determined experimentally or a value determined based on actual operation; this application embodiment does not limit this.

[0128] The aforementioned flushing fluid consumption data includes, in part, the volume of flushing fluid required to vent the flushing pipes, cavities, and drive conduits, and in part, the initial flushing volume entering the drive conduit. Therefore, the initial flushing volume data can be obtained by subtracting the flushing fluid pre-charge data from the flushing fluid consumption data. Thus, the initial flushing volume data can be determined based on the flushing fluid consumption data and the flushing fluid pre-charge data without distinguishing between the pre-charge and flushing stages.

[0129] In some embodiments, the first flushing volume data can also be detected by detecting the moment when the flushing fluid enters the drive conduit. Optionally, the interventional pump includes a drive conduit handle connected to the drive conduit, a cavity formed within the drive conduit handle, and a flushing pressure sensor. Since the drive conduit handle is connected to the drive conduit, and the flushing pressure sensor is located within the drive conduit handle, the distance between the flushing pressure sensor and the flushing fluid inlet of the drive conduit is short. When the flushing pressure sensor detects flushing pressure data, it can be assumed that the flushing fluid has entered the location of the flushing pressure sensor. When the flushing pressure data detected by the flushing pressure sensor meets the flushing pressure condition corresponding to the flushing state, it can be determined that the flushing fluid fills the cavity within the drive conduit handle and enters the drive conduit. Therefore, when the flushing pressure data meets the flushing pressure condition corresponding to the flushing state, the determination of the first flushing volume data based on the drive information can begin. The flushing state can refer to the state under the flushing stage, and the flushing pressure condition can be that the flushing pressure data is greater than or equal to the flushing pressure threshold 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, the determination of the first flushing volume data based on the first flow rate begins. In this way, even without distinguishing between the flushing stage and the pre-filling stage, and without determining the flushing fluid pre-filling data, the starting time of the first flushing volume data can be determined by detecting the flushing pressure data, thereby determining the first flushing volume data.

[0130] By using the above detection methods, the amount of flushing fluid entering the drive duct can be detected more accurately in different application scenarios, greatly reducing the flushing volume error caused by pre-charging and venting of the flushing channel, and improving the detection accuracy of the first flushing volume data.

[0131] In this embodiment, not only can the amount of flushing fluid entering the driving catheter be detected (first flushing volume data), but also the amount of flushing fluid entering the human body through the driving catheter can be accurately detected (second flushing volume data), so as to realize multi-dimensional and accurate display of flushing volume information, making it easier for doctors to view and obtain more flushing volume information.

[0132] The method for detecting the second flushing volume data can be found below. Since the interventional pump is inserted into the human body at a certain point after the flushing of the interventional pump has begun, the entry of the flushing assembly into the flushing phase is not equivalent to the interventional pump being inserted into the human body. Therefore, it is necessary to determine whether the interventional pump is in an interventional state, and then determine whether to start detecting the aforementioned second flushing volume data.

[0133] In some embodiments, when the intervention pump is in an interventional state, the second flushing volume data is determined based on the drive information.

[0134] The interventional state includes the state when the interventional pump is inside the target body.

[0135] Furthermore, the interventional state includes the placement of the pump head in the interventional pump at a location between the left ventricle and the ascending aorta, with the blood inlet of the pump head placed into the left ventricle and the blood outlet of the pump head placed into the ascending aorta.

[0136] With the intervention pump in the intervention state, the flushing flow rate of the flushing fluid entering the target body can be determined based on the first flow rate corresponding to the infusion pump; after determining the flushing flow rate, the amount of flushing fluid entering the target body through the driving catheter is calculated by multiplying the flushing flow rate and the flushing time.

[0137] The calculation of the amount of flushing fluid entering the body is only initiated when the interventional pump is in the interventional state, ensuring the accuracy of the second flushing volume data detection. By separately displaying the amount of flushing fluid entering the target body, users can clearly and accurately know the corresponding flushing volume during clinical operations and can use the amount of flushing fluid entering the target body as a basis for further operations, providing convenience for users.

[0138] In some embodiments, determining whether the interventional pump is in an interventional state includes: obtaining the operating information corresponding to the transcatheter ventricular assist device, and determining whether the interventional pump is in an interventional state by judging the operating information.

[0139] Operational information is used to determine whether the interventional pump is in an interventional state, or, operational information includes operational information obtained from the device itself via catheter ventricular assist device detection.

[0140] Optionally, the operating information includes at least one of the target object's blood pressure data and the first working status data corresponding to the flushing component, but is not limited thereto, and the embodiments of this application do not specifically limit it.

[0141] By utilizing the operational information of the transcatheter ventricular assist device, such as blood pressure data and the working status of the flushing components, it is possible to automatically and accurately determine whether the interventional pump is in an interventional state without manual switching, thus improving the efficiency of interventional state determination, and eliminating the need for additional related sensors.

[0142] The first operational status data includes the operating status of the flushing components.

[0143] Optionally, the first working status data includes at least one of the following: the rinsing component is in a running state and the rinsing component is in a non-running state. However, it is not limited to this, and the embodiments of this application do not specifically limit it.

[0144] Optionally, the operating state includes both the infusion pump and the circulation pump in the flushing assembly being in normal operating condition; the non-operating state includes at least one of the infusion pump and the circulation pump in the flushing assembly being in abnormal operating condition.

[0145] Optionally, abnormal operating conditions include at least one of the infusion pump and the circulation pump not operating, or abnormal operating conditions include at least one of the infusion pump and the circulation pump experiencing operational abnormalities due to mechanical failure.

[0146] For example, determining that the interventional pump is in an interventional state includes at least one of the following methods, but is not limited to:

[0147] • Blood pressure data is used for assessment. If the blood pressure data meets the conditions corresponding to the interventional state, the second flushing volume data is determined based on the driving information. The purpose of assessing the interventional state is to determine the start and end time points for calculating the second flushing volume data, thereby enabling accurate calculation of the amount of flushing fluid entering the target body.

[0148] For example, if the blood pressure data is greater than or equal to the blood pressure threshold corresponding to the interventional state, the interventional pump is determined to be in the interventional state, and the second flushing volume data is determined based on the drive information. Determining whether the interventional pump is in the interventional state through threshold judgment, the simplest method, simplifies the procedure to the greatest extent. In clinical practice, the determination of the interventional state may need to be performed continuously. For medical devices with limited computing power, simplicity and accuracy are particularly important.

[0149] Optionally, if the blood pressure data is greater than or equal to the blood pressure threshold corresponding to the interventional state, the interventional pump is determined to be in the interventional state, and the flushing flow rate of the flushing fluid entering the target body is determined based on the first flow rate corresponding to the infusion pump; after determining the flushing flow rate, the second flushing volume data is calculated by the flushing flow rate and the flushing duration.

[0150] For example, if the blood pressure data does not meet the blood pressure conditions corresponding to the interventional state, it is determined that the interventional pump is not in the interventional state; if the interventional pump is not in the interventional state, the determination of the second flushing volume data is stopped.

[0151] Optionally, if the blood pressure data is lower than the blood pressure threshold corresponding to the interventional state, it is determined that the interventional pump is not in the interventional state, and the determination of the second flushing volume data is stopped.

[0152] Optionally, if no blood pressure data is measured, it can be determined that the interventional pump is not in an interventional state, and the determination of the second flushing volume data can be stopped.

[0153] The above describes a method for determining whether an interventional pump is in an interventional state. This method directly determines whether the interventional pump is in an interventional state by acquiring blood pressure data. In clinical practice, the interventional part of the interventional pump is delivered into the target body through an interventional sheath. After delivery, the interventional sheath is connected to the drive catheter handle, and blood pressure data is measured. Once the measured blood pressure data meets the corresponding blood pressure conditions, it can be determined whether the interventional pump is in an interventional state. This provides a new method for determining the interventional state, which can directly determine whether the interventional pump is in an interventional state by measuring the blood pressure data at the location of the interventional pump, simplifying the determination process.

[0154] • A comprehensive judgment is made based on blood pressure data and first operating status data. If the blood pressure data meets the blood pressure conditions corresponding to the intervention state, and the first operating status data meets the operating conditions of the flushing component corresponding to the intervention state, the second flushing volume data is determined based on the drive information.

[0155] For example, when the blood pressure data is greater than or equal to the blood pressure threshold corresponding to the intervention state and the flushing component is operating normally, it is determined that the intervention pump is in the intervention state, and the flushing flow rate of the flushing fluid entering the target body is determined based on the first flow rate corresponding to the infusion pump; after determining the flushing flow rate, the second flushing volume data is calculated by multiplying the flushing flow rate and the flushing duration.

[0156] Optionally, if the blood pressure data is greater than or equal to the blood pressure threshold corresponding to the interventional state and the flushing component is operating normally, the interventional pump is determined to be in the interventional state, and the flushing flow rate of the flushing fluid entering the target body is determined based on the first flow rate corresponding to the infusion pump; after determining the flushing flow rate, the second flushing volume data is calculated by multiplying the flushing flow rate and the flushing duration.

[0157] For example, if the blood pressure data does not meet the blood pressure condition or the first operating state data does not meet the operating conditions of the flushing component, the determination of the second flushing volume data is stopped.

[0158] Optionally, if the blood pressure data is lower than the blood pressure threshold corresponding to the interventional state, or if the flushing component is not running, it is determined that the interventional pump is not in the interventional state, and the determination of the second flushing volume data is stopped.

[0159] The above describes two methods for determining whether the interventional pump is in an interventional state. Another method is to determine whether the interventional pump is in an interventional state by combining the acquired blood pressure data and the first working state data corresponding to the flushing component. By comprehensively judging whether the interventional pump is in an interventional state by combining blood pressure data and the first working state data, the error rate of interventional state judgment can be greatly reduced, thereby improving the accuracy of displaying the flushing volume information corresponding to the flushing fluid entering the driving catheter.

[0160] In some embodiments, the interventional pump includes a drive catheter handle, a drive catheter, and a pump head. The drive catheter handle includes a blood pressure sensor and a first pressure measurement interface. The first pressure measurement interface is used to connect to a second pressure measurement interface of the interventional sheath. The interventional sheath is used to deliver the drive catheter and the pump head. The blood pressure sensor, the first pressure measurement interface, and the second pressure measurement interface are located in a blood pressure measurement channel. In clinical practice, the interventional portion of the interventional pump is delivered into the target body through the interventional sheath. After delivery, the interventional sheath is connected to the drive catheter handle, thus forming a blood pressure measurement channel between the interventional sheath and the drive catheter handle. That is, the gap between the interventional sheath and the drive catheter, the tubing between the interventional sheath and the drive catheter handle, and the blood pressure sensor form a blood pressure measurement channel, thereby enabling the measurement of blood pressure data. After measuring the blood pressure data, it can be determined whether the interventional pump is in an interventional state.

[0161] In some embodiments, based on a first flow rate, flushing volume information corresponding to at least one component substance in the flushing fluid entering the drive conduit is displayed in association, and / or flushing volume information corresponding to at least one component substance in the flushing fluid entering the target body via the drive conduit is displayed in association.

[0162] The components include the constituent substances of the flushing solution. For example, the flushing solution may include glucose, heparin, and physiological saline, but it is not limited to these. The embodiments of this application do not specifically limit the constituent substances of the flushing solution.

[0163] The flushing volume information corresponding to the component substances includes the output volume corresponding to the component substances.

[0164] In some embodiments, the flushing flow rate of the flushing fluid entering the driving catheter can be determined based on the first flow rate corresponding to the infusion pump. After determining the flushing flow rate of the flushing fluid entering the driving catheter, the flushing volume information corresponding to at least one component in the flushing fluid entering the driving catheter is calculated using the flushing flow rate, flushing duration, and component concentration of at least one component. Since the flushing fluid is split after entering the interventional pump, with a portion circulating in the cavity of the interventional pump and a portion entering the driving catheter, the flushing volume information corresponding to at least one component in the flushing fluid entering the driving catheter can be calculated separately using the above method. Furthermore, the separately displayed flushing volume information corresponding to at least one component allows the user to clearly and accurately know the flushing volume corresponding to at least one component in the flushing fluid entering the driving catheter during clinical operations.

[0165] In some embodiments, when the interventional pump is in the interventional state, the flushing flow rate of the flushing fluid entering the target body can be determined based on the first flow rate corresponding to the infusion pump. After determining the flushing flow rate, the flushing volume information corresponding to at least one component in the flushing fluid entering the target body is calculated using the flushing flow rate, flushing duration, and component concentration corresponding to at least one component. Since the flushing fluid is split after entering the interventional pump, with part circulating in the cavity of the interventional pump and part entering the drive catheter, the flushing volume information corresponding to at least one component in the flushing fluid entering the target body can be calculated separately using the above method. Furthermore, the separately displayed flushing volume information corresponding to at least one component allows the user to clearly and accurately know the flushing volume corresponding to at least one component in the flushing fluid entering the target body during clinical operations.

[0166] For example, in the case of a flushing solution containing glucose, in clinical applications, users can clearly and accurately determine the amount of glucose that has entered the target body.

[0167] For example, such as Figure 6 The diagram showing the flushing volume information is as follows: Figure 6 As shown in Figure (a), the flushing solution configuration interface 10 includes parameters of the flushing solution's components and its volume. For example, the glucose content is 5 mg, the heparin content is 5 Iu, and the flushing solution volume is 200 ml. The components shown in this embodiment are only glucose and heparin, but are not limited to these. Figure 6 As shown in Figure (b), during the flushing process, flushing flow rate, flushing pressure, remaining flushing time, and flushing volume information 40 are displayed. The flushing volume information 40 includes the current flushing volume and the total flushing volume. By viewing the displayed data, the user can accurately obtain the flushing volume information corresponding to at least one component substance in the flushing fluid that has entered the target object or the drive conduit.

[0168] For example, firstly, the flushing flow rate and flushing duration are multiplied to obtain the flushing volume of the flushing fluid; then, the flushing volume is multiplied by the concentration of at least one component to obtain the flushing amount information corresponding to at least one component.

[0169] In some embodiments, the flushing volume information may also include at least one of the remaining flushing time, current flushing volume, and total flushing volume.

[0170] The current flush volume can refer to the flush volume at the start of this flush; the total flush volume can refer to the sum of flush volumes corresponding to different flush counts. Alternatively, the current flush volume can refer to the cumulative flush volume since the last update of the flush fluid information; the total flush volume can also refer to the sum of flush volumes during the entire operation period.

[0171] Optionally, the current flushing volume includes the amount of flushing fluid entering the drive conduit corresponding to this flushing, or the amount of flushing fluid entering the target body through the drive conduit corresponding to this flushing.

[0172] Optionally, the total flushing volume includes the sum of flushing fluid entering the drive conduit during operation, or the sum of flushing fluid entering the target body via the drive conduit during operation. The remaining flushing time can refer to the ratio of the remaining flushing fluid volume to the current flushing flow rate.

[0173] Optionally, the first flushing volume data may include at least one of the cumulative flushing fluid entering the drive conduit during the first time period and the cumulative flushing fluid entering the drive conduit during the second time period, but is not limited thereto.

[0174] Optionally, the second flushing volume data may include at least one of the following: the cumulative amount of flushing fluid entering the target body through the drive catheter during the first time period and the cumulative amount of flushing fluid entering the target body through the drive catheter during the second time period, but is not limited thereto.

[0175] The first time period mentioned above can be the time period after the most recent flushing operation, such as the time period after the most recent start of the flushing pump; or it can be the time period after the most recent flushing fluid data configuration operation, such as the time period after the most recent configuration of new fluid bag information.

[0176] The aforementioned second time period can be the entire operating period of the control device. This application does not limit this to any particular time period.

[0177] In summary, the method provided in this embodiment obtains the driving information corresponding to the flushing component, which includes parameter information of the flushing component driving the flushing fluid; based on the driving information, it displays the flushing volume information corresponding to the flushing fluid entering the driving catheter. This application can display the flushing volume information corresponding to the flushing fluid entering the driving catheter separately, or, when the interventional pump is in an interventional state, separately display the flushing volume information corresponding to the flushing fluid entering the target body, enabling users to clearly and accurately know the flushing volume corresponding to the flushing fluid entering the driving catheter or the target body during clinical operations. Furthermore, it provides two methods for determining whether the interventional pump is in an interventional state: users can directly determine based on blood pressure data, or they can make a comprehensive judgment based on blood pressure data and the first working state data corresponding to the flushing component. In clinical operations, users can flexibly choose the judgment method, increasing convenience.

[0178] Optionally, upon detecting the aforementioned first and second flushing volume data, corresponding alarms or prompts can be issued based on these data. For example, a prompt could be issued to the user indicating that the amount of certain substances in the flushing solution is insufficient or excessive.

[0179] To achieve the above prompts, the control device can be configured with flushing volume alarm conditions. If either the first or second flushing volume data meets the flushing volume alarm conditions, flushing volume prompt information can be output.

[0180] The aforementioned flushing volume alarm conditions include a first flushing volume alarm condition corresponding to the first flushing volume data, and / or a second flushing volume alarm condition corresponding to the second flushing volume data. The aforementioned flushing volume alarm conditions may include the first flushing volume data or the second flushing volume data being greater than or equal to the corresponding flushing volume threshold, or less than the corresponding flushing volume threshold. The flushing volume alarm conditions and flushing volume thresholds can be set and adjusted according to actual application scenarios, and this application embodiment does not limit this.

[0181] The above-mentioned alerts may be extremely important in clinical applications. For example, patients requiring interventional pump intervention may have other diseases or symptoms besides heart problems, necessitating control of the dosage of relevant substances in the irrigation fluid. The concentration of relevant substances in the irrigation fluid is known, and the volume of irrigation fluid entering the patient's body through the driving catheter can also be detected using the above method. Therefore, the cumulative amount of relevant substances entering the patient's body can be determined, i.e., the irrigation volume information corresponding to at least one component of the irrigation fluid entering the patient's body. Based on the above-mentioned irrigation volume alarm conditions, it can be determined whether the irrigation volume corresponding to at least one component entering the body is within a safe range. For example, if the patient has diabetes, the amount of glucose entering the body needs to be controlled within a safe range. Therefore, the above-mentioned second irrigation volume alarm condition could include being greater than or equal to a glucose accumulation threshold. If the cumulative amount of glucose entering the body is greater than or equal to the glucose accumulation threshold, a glucose overdose alert is triggered. For example, if the target individual requires blood clotting, the amount of heparin entering the body needs to be controlled within a safe range. Therefore, the aforementioned second flushing volume alarm condition could include being greater than or equal to the first heparin cumulative threshold. If the cumulative amount of heparin entering the body is greater than or equal to the first heparin cumulative threshold, a heparin overdose warning message is triggered. Similarly, if the target individual requires anticoagulation, the amount of heparin entering the body needs to be controlled within a safe range. Therefore, the aforementioned second flushing volume alarm condition could also include being less than or equal to the second heparin cumulative threshold. If the cumulative amount of heparin entering the body is less than or equal to the second heparin cumulative threshold, a heparin underdose warning message is triggered. This also demonstrates the importance and necessity of accurately detecting second flushing volume data.

[0182] The above-mentioned prompts can effectively alert users to abnormal flushing volumes, thereby improving the safety of the interventional pump operating via catheter-guided ventricular assist device.

[0183] Figure 7This is a flowchart illustrating an exemplary embodiment of a method for detecting flushing information in a transcatheter ventricular assist device (TAVED). The method is applied to a TAVED. The method includes:

[0184] Step 602: In response to the flushing fluid data configuration operation corresponding to the liquid storage device, obtain flushing fluid parameter data.

[0185] The flushing fluid data configuration operation includes at least one of the following: flushing fluid data entry operation and flushing fluid data quick entry operation, but is not limited thereto. This application embodiment does not specifically limit this.

[0186] Optionally, the flushing fluid data configuration operation can be triggered on the flushing fluid configuration interface, or operated through an input device, or operated through a combination of interface triggering and input device, but is not limited thereto, and the embodiments of this application do not specifically limit it.

[0187] Fluid parameter data is used to represent the parameter information of the flushing fluid.

[0188] Optionally, the flushing fluid parameter data includes at least one of the following: volume, weight, density, storage material, composition, component concentration, flushing fluid number, flushing fluid name, production date, and shelf life. However, it is not limited to these, and the embodiments of this application do not specifically limit this. Some parameters in the flushing volume information determined in step 304 above may need to be determined based on the flushing fluid parameter data. For example, the flushing volume of a component needs to be determined based on the concentration of the corresponding component in the flushing fluid and the flushing volume of the flushing fluid. For example, the flushing volume of a component = the concentration of the component × the flushing volume of the flushing fluid.

[0189] Optionally, the flushing fluid parameter data can be entered by sequentially inputting parameters such as the composition, concentration, and concentration of the flushing fluid; or, the flushing fluid parameter data can be quickly entered by inputting the flushing fluid number or name, but is not limited to these methods.

[0190] For example, the input of flushing fluid parameter data can be done by sequentially entering the components of the flushing fluid, such as glucose and heparin, and entering their respective contents or component concentrations in the parameter boxes for glucose and heparin, while also entering the volume of the flushing fluid.

[0191] For example, when the flushing fluid is the standard configuration, the flushing fluid information can be quickly entered by inputting the flushing fluid number or flushing fluid name.

[0192] Optionally, the flushing fluid parameter data includes at least one of preset flushing fluid parameter data and recorded flushing fluid parameter data, but is not limited thereto, and the embodiments of this application do not specifically limit this.

[0193] The preset flushing fluid parameter data includes pre-entered data or the last entered flushing fluid parameter data, which can be directly called in the quick entry operation of flushing fluid data.

[0194] In some embodiments, a flushing fluid configuration interface is displayed, and flushing fluid parameter data is obtained in response to the input operation of flushing fluid parameter data.

[0195] In some embodiments, a flushing fluid configuration interface is displayed, and flushing fluid parameter data is obtained in response to a quick input operation.

[0196] In one possible implementation, the aforementioned irrigation fluid configuration interface includes at least one set of combined data corresponding to the irrigation fluid parameters. For example, the irrigation fluid parameters include concentration parameters, mass parameters, and volume parameters corresponding to the irrigation fluid substances. Each set of combined data includes parameter data corresponding to each of the above parameters. This combined data can be preset parameter data for each of the above parameters; commonly used parameter data can typically be selected. For instance, the glucose concentration in the irrigation fluid is usually 5%, and the irrigation fluid volume is usually 500 ml. Therefore, in a certain set of combined data, the glucose concentration could be 5%, and the irrigation fluid volume could be 500 ml. The purpose of setting at least one set of combined data is primarily to allow users to quickly configure the various parameters of the irrigation fluid. Under normal circumstances, there is no need to use the keyboard to configure the irrigation fluid parameter data, reducing the complexity of the configuration operation and shortening the irrigation fluid configuration time. For critical clinical situations, reducing configuration complexity and shortening configuration time are crucial.

[0197] Users can select at least one set of combined data that matches the flushing fluid parameters of the reservoir device to be replaced, and trigger an application operation for that combined data to quickly configure the flushing fluid parameter data. Specifically, in response to the application operation for the target combined data, the device determines the target combined data as the aforementioned flushing fluid parameter data; wherein, the target combined data is a set of combined data selected from at least one set of combined data, and the flushing fluid data configuration operation includes the application operation.

[0198] Optionally, the above application operations can be received through application controls corresponding to the combined data. These application controls can be application options displayed in the flushing fluid configuration interface or physical buttons on the control device; this embodiment does not limit the specific application controls.

[0199] When the control device presets multiple sets of combined data, the flushing fluid configuration interface can include switching controls corresponding to each set of combined data. Similar to application controls, these switching controls can be switching options displayed in the flushing fluid configuration interface or physical buttons on the control device; this embodiment does not limit this. Users can operate the corresponding switching controls to view the data information of a certain set of combined data, thereby determining whether to apply that set of combined data. The control device responds to the selection operation of the target switching control by displaying the target combined data.

[0200] Taking the configuration of flushing fluid data as an example, which is triggered by the interface, the flushing fluid configuration interface is displayed, and the input controls are shown on the interface. The input controls are used to enter the flushing fluid parameter data.

[0201] Optionally, the flushing fluid configuration interface may be displayed in at least one of the following ways, but is not limited to:

[0202] • The flushing fluid configuration interface is displayed as a pop-up window at the top of the user interface;

[0203] • The flushing fluid configuration interface replaces the display on the user interface; that is, the flushing fluid configuration interface covers the user interface.

[0204] • The flushing fluid configuration interface and the user interface are displayed side by side.

[0205] like Figure 8 The illustrated user interface shows that before rinsing with the rinsing fluid, rinsing fluid parameter data needs to be entered. A rinsing control 701, labeled as "two water droplets," is displayed at the bottom of the user interface. Triggering the rinsing control 701 accesses the rinsing interface. Responding to rinsing fluid data configuration operations corresponding to the storage device, such as clicking the "New Liquid Bag" button, the rinsing fluid configuration interface is displayed.

[0206] like Figure 9 The diagram shown illustrates the flushing fluid configuration interface. After triggering the flushing control 805, the flushing fluid configuration interface 801 is displayed. The flushing fluid configuration interface 801 displays an input control 802. By triggering the input control 802, flushing fluid parameter data 803 can be entered. After the flushing fluid parameter data 803 is entered, if the entered flushing fluid parameter data 803 does not meet the requirements, such as being out of range or containing a value of 0, further prompts will be given, and the entered flushing fluid parameter data 803 cannot be saved. If the entered flushing fluid parameter data 803 meets the requirements and a confirmation save instruction is received, such as clicking the OK button 804, the current flushing fluid parameter data 803 is updated and saved.

[0207] Optionally, the operation that triggers the flushing control includes at least one of single click, double click, triple click, long press, and swipe, but is not limited thereto, and the embodiments of this application do not specifically limit this.

[0208] Step 604: If the flushing fluid parameter data does not meet the preset parameter range conditions, restrict the saving of the flushing fluid parameter data.

[0209] For example, during the process of entering flushing fluid parameter data, if the flushing fluid parameter data does not meet the preset parameter range conditions, the saving of flushing fluid parameter data is restricted.

[0210] The preset parameter range conditions include pre-set parameter ranges. For example, if the preset parameter range for concentration values ​​is 1%-50%, then saving the data will be prohibited if 75% is entered.

[0211] The preset parameter range conditions include at least one of whether the parameter value exceeds the range or whether the parameter is 0, but are not limited thereto. This application embodiment does not specifically limit this.

[0212] When entering new flushing fluid parameter data, the system checks whether the entered flushing fluid parameter data meets the preset parameter range conditions. If the entered flushing fluid parameter data meets the preset parameter range conditions, the flushing fluid parameter data is saved; if the entered flushing fluid parameter data does not meet the preset parameter range conditions, such as being out of range or containing a value of 0, the system will restrict the saving of the flushing fluid parameter data.

[0213] By limiting the storage of data outside the acceptable range, incorrect data input can be avoided in one situation (when the liquid bag is used correctly), and the user can be prompted to replace the correct and valid liquid bag in another situation (when the liquid bag is incorrect), thereby ensuring the accuracy of the flushing volume information detection.

[0214] In some embodiments, a replenishment prompt message is displayed in response to the fact that the remaining flushing fluid in the reservoir is less than the remaining threshold.

[0215] The fluid replenishment prompt message is used to indicate when flushing fluid parameter data needs to be entered.

[0216] Optionally, the fluid replenishment prompt is a notification message, or the fluid replenishment prompt provides an entry point for configuring flushing fluid parameters.

[0217] The flushing fluid parameter configuration input is used to trigger the control equipment to enter the flushing fluid parameter configuration state.

[0218] The fluid replenishment prompt information provides an entry point for configuring flushing fluid parameters in at least one of the following ways, but is not limited to:

[0219] • The information box containing the fluid replenishment prompt is used as the entry control for configuring the flushing fluid parameters. By triggering any position within the information box containing the fluid replenishment prompt, one can directly enter the flushing fluid parameter configuration state;

[0220] • A control for configuring flushing fluid parameters has been added to the fluid replenishment prompt message. Activating this control will take you to the flushing fluid parameter configuration screen.

[0221] Optionally, the flushing fluid data configuration operation includes at least one of the following methods, but is not limited to:

[0222] • Enter the flushing fluid parameters in the input box via the touchscreen or keyboard;

[0223] • Display input box and knob control. Adjust the flushing fluid parameters by rotating the knob control to enter the flushing fluid parameters;

[0224] • Display an input box and a numeric adjustment control. Adjust the "+" and "-" controls in the numeric adjustment control to increase or decrease the flushing fluid parameters, thereby realizing the input of flushing fluid parameters.

[0225] When the flushing fluid parameter is configured, the control device can receive flushing fluid data configuration operations to update the flushing fluid information corresponding to the storage device.

[0226] The method provided in this embodiment displays a replenishment prompt when the remaining amount of flushing fluid in the storage device is less than the remaining threshold. The replenishment prompt reminds the user to add new flushing fluid in a timely manner. At the same time, the replenishment prompt provides an entry point for flushing fluid parameter configuration. By providing an entry point for flushing fluid parameter configuration, the user can quickly enter the flushing fluid parameter configuration state, making the flushing fluid data configuration operation more convenient and faster, and improving the operation efficiency.

[0227] like Figure 10 The diagram illustrates a fluid replenishment prompt. When the remaining flushing fluid is below a threshold, a fluid replenishment prompt 901 is displayed as a floating window in the user interface. The prompt 901 includes the message "Flushing fluid level is below the threshold" and a flushing fluid parameter configuration entry 902. Accessing the flushing fluid configuration interface via this entry allows the user to continue using the configuration interface. Furthermore, if incorrect data or a value of 0 is entered after triggering the flushing fluid parameter configuration entry 902, the configuration interface will remain displayed and cannot be exited unless a cancellation control is triggered or the interface automatically exits after a preset time. However, the original flushing fluid information will be retained. For example, if the flushing fluid volume is 200ml and 180ml has been flushed, the fluid replenishment prompt 901 will be displayed as a floating window in the user interface to remind the user to replenish the flushing fluid.

[0228] In addition, errors in the flushing fluid data configuration may occur, such as the entered flushing fluid parameter data not matching the actual flushing fluid parameters of the storage device. Therefore, a flushing fluid parameter modification function is provided in the control device. Optionally, the control device updates the flushing fluid parameter data in response to the flushing fluid data modification operation corresponding to the storage device. Specifically, in one possible implementation, the flushing fluid configuration interface includes a flushing fluid parameter modification entry. Based on this entry, the control device can receive the flushing fluid data modification operation, such as selecting the corresponding parameter through a parameter selection operation, configuring the correct flushing fluid parameter data for that parameter through the numeric keypad, and saving the modified flushing fluid parameter data in response to a confirmation command, thereby updating the flushing fluid parameter data.

[0229] In some examples, the liquid storage device is a liquid bag, which is replaceable. If the current liquid bag's parameters are configured incorrectly, the system can receive a modification operation for the flushing fluid parameters of the current liquid bag, updating the parameter data of the current liquid bag. Similarly, if a historical liquid bag's parameters are configured incorrectly, the system can receive a modification operation for the flushing fluid parameters of the historical liquid bag, updating the parameter data of the historical liquid bag.

[0230] The flushing volume information may be determined based on flushing fluid parameter data. Therefore, after the flushing fluid parameter data is updated, the flushing volume information needs to be updated based on the updated flushing fluid parameter data. Optionally, the control device can update the flushing volume information based on the currently updated parameter data of the liquid bag, or it can update the flushing volume information based on the historical updated parameter data of the liquid bag.

[0231] In some examples, after modifying the flushing fluid parameter data (such as modifying the parameter data of the liquid bag), the flushing fluid consumption may not need to be re-determined. The parameters that need to be calculated for flushing include at least one of the following: flushing volume information corresponding to at least one component substance, and the remaining flushing fluid corresponding to the storage device.

[0232] If the concentration of at least one component is updated, the corresponding flushing volume information, such as mass, needs to be updated and re-determined. For example, the flushing volume corresponding to the updated component = updated concentration × flushing solution volume.

[0233] When the volume of flushing fluid corresponding to the storage device is updated, the remaining amount of flushing fluid is updated. For example, the remaining amount of flushing fluid = the updated volume of flushing fluid - the amount of flushing fluid used.

[0234] Optionally, if the aforementioned flushing fluid parameter data is not available, the activation of transcatheter ventricular assist devices may be restricted. For example, the flushing pump or interventional pump may be prohibited from activation.

[0235] During the operation of the interventional pump, it needs to be continuously flushed with irrigation fluid. Therefore, accurate determination of the irrigation fluid parameters is crucial for precisely detecting the usage and remaining volume of the irrigation fluid. Starting the pump without configuring these parameters can result in some irrigation fluid information not being recorded, leading to errors in irrigation volume detection and posing risks. For example, pumping air into the pump after the irrigation fluid has been used up is strictly prohibited. These restrictions effectively prevent such errors. Furthermore, they remind users to install and configure the irrigation fluid parameters before starting the pump, preventing erroneous operation and ensuring the safety of the target group, such as the patient.

[0236] In summary, the method provided in this embodiment acquires flushing fluid parameter data through a flushing fluid data configuration operation and checks the input data to avoid erroneous data input. This application improves input efficiency by checking whether the input flushing fluid parameter data meets preset parameter range conditions, thus avoiding erroneous data input.
