Description

Technical Field

[0001] The present application relates to the field of medical device control technology, and in particular to a control method for a flushing system and related equipment. Background Art

[0002] During interventional surgery, it is usually necessary to monitor the body's arterial pressure. When measuring arterial pressure, since the arterial pressure measurement channel is connected to the blood, the blood will gradually enter the filling liquid of the pressure measurement channel due to diffusion.

[0003] At present, in order to prevent blood from staying in the pressure measuring channel for a long time and causing blockage, the conventional practice is to add a liquid bag at the entrance of the arterial pressure measuring channel, and the liquid bag and the pressure measuring channel are connected by a manual valve; by manually opening the valve, and under the pressure of the pressurized bag, the liquid in the liquid bag flows into the arterial pressure measuring channel to achieve flushing of the pressure measuring channel. This method requires manual operation and it is very easy to forget to flush in time. After the valve is opened, if it is forgotten to be closed, too much flushing fluid will continue to enter the human body, endangering the patient's life. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0090] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0091] Before introducing the control method embodiment of the flushing system of the present application, a flushing system is first introduced. Figure 1 , Figure 1 It is a structural schematic diagram of a flushing system provided in an embodiment of the present application, wherein the flushing system comprises a preset flushing pump 1, an input tube 2 corresponding to the flushing liquid, an arterial pressure measuring tube 3, a flushing tube 4 corresponding to the interventional pump, and a flow path control electronic device 5;

[0092] The input tube 2 is connected to the arterial pressure measuring tube 3 to form a first flow path, and the input tube 2 is connected to the flushing tube 4 to form a second flow path. The first flow path is used to deliver flushing fluid to the arterial pressure measuring channel corresponding to the interventional pump, and the second flow path is used to deliver flushing fluid to the interventional pump flushing channel corresponding to the interventional pump.

[0093] The flow path control electronic device 5 is used to control the connection state of the first flow path and / or the second flow path; the preset flushing pump 1 is used to pump flushing fluid to the arterial pressure measurement channel and / or the interventional pump flushing channel.

[0094] Optionally, the flushing tube 4 and the arterial pressure measuring tube 3 share a liquid storage device.

[0095] In the embodiment of the present application, the interventional pump is an interventional blood pump, which is suitable for providing temporary left ventricular circulation assistance during high-risk PCI surgery, including but not limited to the following patients: elderly, reduced heart function, and severe coronary artery disease; suitable for providing temporary or short-term left ventricular mechanical circulation assistance for patients with acute heart failure and cardiogenic shock caused by various reasons, including but not limited to those caused by acute myocardial infarction, cardiac surgery, and explosive myocarditis; suitable for patients who need left ventricular decompression during extracorporeal membrane oxygenation (ECMO) support.

[0096] The above-mentioned preset flushing pump can be a peristaltic pump or a centrifugal pump, which is not limited in the embodiment of the present application.

[0097] The flushing system of the embodiment of the present application delivers liquid through the preset flushing pump 1, so that the flushing liquid flows from the input tube 2 into the arterial pressure measuring tube 3 and / or the flushing tube 4 corresponding to the interventional pump, so as to flush the arterial pressure measuring channel and / or the interventional pump flushing channel, prevent blood from entering the driving catheter of the interventional pump to produce thrombus, and prevent blood from clotting in the arterial pressure measuring channel; according to the channel that actually needs to be flushed, the connection state of the first flow path and / or the second flow path can be controlled by the flow path control electronic device 5. Here, taking the control of the first flow path as an example, the flow path control electronic device 5 can control the first flow path to be in a connected state. In the connected state, the preset flushing pump 1 is operated, so that the flushing liquid flows from the input tube 2 into the arterial pressure measuring tube 3; the flow path control electronic device 5 can also control the first flow path to be in a blocked state. In the blocked state, even if the preset flushing pump 1 is operated, the flushing liquid will not flow from the input tube 2 into the arterial pressure measuring tube 3; the principle of controlling the second flow path is the same and will not be repeated.

[0098] The following is based on Figure 1 The flushing system of the present application introduces an embodiment of the control method of the flushing system, which can be applied to control the host. Figure 2 As shown, Figure 2 : is a flow chart of a control method of a flushing system provided in an embodiment of the present application, and the method may include the following steps:

[0099] S201: upon receiving first flushing instruction information corresponding to the arterial pressure measurement channel, controlling the flow path control electronic device to switch from the first working state to the preset working state, and controlling the preset flushing pump to pump flushing liquid to the arterial pressure measurement channel in a preset working mode;

[0100] The first working state refers to the working state of the flow path control electronic device before the flushing instruction is triggered. The flow path control electronic device controls the first flow path to be in a connected state under the preset working state.

[0101] First, in the embodiment of the present application, the first flushing instruction information corresponding to the arterial pressure measurement channel is used to instruct the arterial pressure measurement channel to be flushed. The first flushing instruction information can be automatically generated by the control host or triggered when a preset condition is met, or it can be a manual operation detected by the control host. In an exemplary embodiment, the above-mentioned first flushing instruction information includes but is not limited to: a timed flushing instruction generated at a preset time interval, an abnormal flushing instruction triggered when an abnormality is detected in the arterial pressure data, and a flushing operation instruction for the arterial pressure measurement channel received by the human-computer interaction operation module; three possible embodiments are introduced below.

[0102] In a first possible embodiment, the first flushing instruction information includes a timed flushing instruction generated at a preset time interval; then, the above S201 may include: when receiving the timed flushing instruction, controlling the flow path control electronic device to switch from the first working state to the preset working state, and controlling the preset flushing pump to pump flushing fluid to the arterial pressure measurement channel in a preset working mode.

[0103] The preset time interval can be set according to actual needs, for example, a few minutes or a few hours. In this way, by generating flushing instructions at a fixed time, flushing fluid is regularly injected into the arterial pressure measurement channel to flush the blood in the arterial pressure measurement channel; the entire process is automatically operated without manual operation, which reduces the burden on operators and avoids possible errors caused by manual operation and the impact of differences between manual operators.

[0104] In a second possible embodiment, the first flushing instruction information includes an abnormal flushing instruction triggered when the arterial pressure data detects an abnormality; then, the above S201 may include: when receiving an abnormal flushing instruction, controlling the flow path control electronic device to switch from the first working state to a preset working state, and controlling the preset flushing pump to pump flushing fluid to the arterial pressure measurement channel in a preset working mode.

[0105] In this embodiment, the control host can determine whether the arterial pressure measurement channel needs to be flushed based on the arterial pressure data; for example, the real-time collected arterial pressure data can be judged based on the standard arterial pressure data range; when the arterial pressure data drifts, is abnormal, etc., it indicates that blood may be refluxed in the arterial pressure measurement channel, and an abnormal flushing instruction is generated at this time to flush the arterial pressure measurement channel in time to avoid blood clotting in the arterial pressure measurement channel. In this way, it can be ensured that the arterial pressure measurement channel is flushed in time when it needs to be flushed. Compared with the timed flushing method, the number of times that flushing is not required can be reduced, and the frequent switching of the working state of the flow path control electronic device can be avoided.

[0106] In a third possible embodiment, the first flushing instruction information includes a flushing operation instruction for the arterial pressure measurement channel received by the human-computer interaction operation module; then, the above S201 may include: when receiving the flushing operation instruction, controlling the flow path control electronic device to switch from the first working state to the preset working state, and controlling the preset flushing pump to pump flushing fluid to the arterial pressure measurement channel in a preset working mode.

[0107] In this embodiment, the control host is provided with a human-computer interaction operation module, which can receive a flushing operation instruction for the arterial pressure measurement channel, and the flushing operation instruction can include at least one of a voice flushing instruction of the operator, a gesture flushing instruction, and a flushing instruction generated based on a display interface. Accordingly, the human-computer interaction operation module needs to be provided with corresponding interactive devices, such as a microphone, a camera, and a display screen. In this way, the operator can use any one or more of voice, gesture, and touch to manually trigger the flushing function of the arterial pressure measurement channel, and the triggering method is diverse and flexible, which can improve the convenience of the operator.

[0108] Secondly, in the embodiment of the present application, the flow path control electronic device 5 can have a variety of different working states. Under the control of the control host, the flow path control electronic device 5 can switch between different working states. The flow path control electronic device 5 can be in a first working state before the flushing instruction corresponding to the arterial pressure measurement channel is triggered. When the first flushing instruction information corresponding to the arterial pressure measurement channel is received, the control host controls the flow path control electronic device 5 to switch from the first working state to a preset working state. In the preset working state, the flow path control electronic device 5 controls the first flow path to be in a connected state to achieve flushing of the arterial pressure measurement channel.

[0109] In some possible embodiments, Figure 3 As shown, before S201, the control method of the embodiment of the present application may further include:

[0110] S200: When receiving second flushing instruction information corresponding to the interventional pump flushing channel, controlling the flow control electronic device to a first working state, and controlling a preset flushing pump to pump flushing liquid to the interventional pump flushing channel in a first working mode.

[0111] First, in the embodiment of the present application, the second flushing instruction information corresponding to the interventional pump flushing channel is used to instruct flushing the interventional pump flushing channel. The second flushing instruction information is similar to the first flushing instruction information, and can be automatically generated by the control host or triggered when a preset condition is met, or it can be a human operation detected by the control host. The specific embodiment can refer to the embodiment of the first flushing instruction information above, and will not be repeated here.

[0112] Secondly, in the embodiment of the present application, the control host controls the flow path control electronic device 5 to the first working state when receiving the second flushing instruction information corresponding to the interventional pump flushing channel. In the first working state, the flow path control electronic device 5 controls the second flow path to be in a connected state. In the first working state, the preset flushing pump 1 is operated, so that the flushing liquid flows from the input tube 2 into the flushing tube 4 corresponding to the interventional pump, and then enters the flushing liquid inlet of the interventional pump drive catheter handle to flush the interventional pump flushing channel.

[0113] Secondly, in the embodiment of the present application, the preset flushing pump 1 can have a plurality of different working modes, and different working modes can have different target flushing volumes. The preset flushing pump 1 works based on a first target flushing volume in a first working mode, and the first target flushing volume refers to the flushing volume required to flush the flushing channel of the interventional pump. The first target flushing volume can be a fixed value or a value that changes over time.

[0114] During the operation of the interventional pump, it is necessary to continuously flush the interventional pump. Therefore, the above-mentioned first working state can be the default working state that the flow path control electronic device needs to maintain after starting the interventional pump flushing. Then, when the arterial pressure measuring channel needs to be flushed, the arterial pressure measuring channel is flushed again. The switching from the conventional flushing mode to the arterial pressure measuring channel flushing mode can be realized, and at the same time, the two flushing requirements of the interventional pump during operation (one is the flushing requirement of the interventional pump lumen and catheter, and the other is the flushing requirement of the interventional pump arterial pressure measuring channel).

[0115] In some possible embodiments, the control method of the embodiment of the present application may also include: under different working modes of the preset flushing pump, according to the flushing parameters corresponding to the different working modes, controlling the preset flushing pump to pump flushing fluid to the arterial pressure measurement channel and / or the interventional pump flushing channel.

[0116] Here, the flushing parameter includes at least one of a target flushing volume, a rotation speed, and a duration. Exemplarily, in the first working mode, the flushing pump 1 can be preset to pump flushing liquid to the interventional pump flushing channel at a first target flushing volume, a first rotation speed, and a first duration.

[0117] It can be understood that in the above embodiments, the control host controls the flow path control electronic device 5 to switch to the corresponding working state according to the different flushing instruction information received, so as to flush the arterial pressure measurement channel or the interventional pump flushing channel.

[0118] A possible embodiment of the flow path control electronic device is described below. The flow path control electronic device 5 includes an electrically controlled pipeline clamping device, which includes a first clamping mechanism and a second clamping mechanism, wherein the first clamping mechanism clamps the arterial pressure measuring tube 3, and the second clamping mechanism clamps the flushing tube 4. In this embodiment, the flow path control electronic device 5 can control the connection state of the first flow path and / or the second flow path by clamping, and the first clamping mechanism and the second clamping mechanism can respectively control the clamping state of the arterial pressure measuring tube 3 and the flushing tube 4, so that the flow path control is more simple and efficient, and the structural complexity is low.

[0119] Based on this, in some possible embodiments, the flow path control electronic device 5 can control the second flow path to be in a non-connected state under a preset working state;

[0120] Then, controlling the flow path control electronic device in S201 to switch from the first working state to the preset working state may include: controlling the first clamping mechanism to release the arterial pressure measuring tube 3 , and controlling the second clamping mechanism to clamp the flushing tube 4 .

[0121] It can be understood that in this embodiment, when the arterial pressure measuring channel is flushed, the flushing of the interventional pump flushing channel is stopped, so as to isolate the flushing stages of the two and enable the arterial pressure measuring channel to be flushed better at a preset target flushing volume.

[0122] Correspondingly, controlling the preset flushing pump to pump flushing fluid to the arterial pressure measuring channel in the preset working mode in S201 may include: controlling the preset flushing pump 1 to pump flushing fluid to the arterial pressure measuring channel in the second working mode.

[0123] In an embodiment of the present application, when flushing different channels, the preset flushing pump 1 adopts different working modes. When only flushing the arterial pressure measurement channel, the control host can control the preset flushing pump 1 to pump flushing liquid to the arterial pressure measurement channel in the second working mode; the preset flushing pump 1 works based on the second target flushing volume in the second working mode, and the second target flushing volume refers to the flushing volume required to flush the arterial pressure measurement channel. Similarly, the second target flushing volume can be a fixed value or a value that changes with time. Furthermore, in the second working mode, the preset flushing pump 1 can pump flushing liquid to the arterial pressure measurement channel at the second target flushing volume, the second speed and the second duration.

[0124] Alternatively, in some other possible embodiments, the flow path control electronic device 5 can control the second flow path to be in a connected state in a preset working state;

[0125] Then, controlling the flow path control electronic device in S201 to switch from the first working state to the preset working state may include: controlling the first clamping mechanism to release the arterial pressure measuring tube 3, and controlling the second clamping mechanism to clamp the flushing tube 4 according to the preset extrusion parameters.

[0126] It can be understood that in this embodiment, when the arterial pressure measurement channel is flushed, the flushing of the interventional pump flushing channel is not stopped, but the connectivity of the interventional pump flushing channel is adjusted, that is, the second clamping mechanism is controlled to clamp the flushing tube 4 according to the preset extrusion parameter, so that the second flow path is still in a connected state but the flushing amount is reduced. The smaller the extrusion parameter, the better the connectivity of the flow path, that is, the smoother the flow path; conversely, the larger the extrusion parameter, the worse the connectivity of the flow path, that is, the flow path tends to be blocked.

[0127] In this way, the arterial pressure measurement channel and the interventional pump flushing channel can be flushed synchronously. The arterial pressure measurement channel can also be flushed without stopping the flushing of the interventional pump flushing channel. The flushing volume distribution of different channels can also be achieved by adjusting the extrusion parameters, while meeting the flushing volume requirements of the two channels.

[0128] Accordingly, controlling the preset flushing pump to pump flushing fluid to the arterial pressure measurement channel in the preset working mode in S201 may include: controlling the preset flushing pump 1 to pump flushing fluid to the interventional pump flushing channel and the arterial pressure measurement channel in the third working mode.

[0129] Here, when flushing the arterial pressure measurement channel and the interventional pump flushing channel at the same time, the control host can control the preset flushing pump 1 to pump flushing liquid to the interventional pump flushing channel and the arterial pressure measurement channel in the third working mode. The preset flushing pump 1 works based on the third target flushing volume in the third working mode, and the third target flushing volume refers to the flushing volume required to flush the interventional pump flushing channel and the arterial pressure measurement channel at the same time. Similarly, the second target flushing volume can be a fixed value or a value that changes with time. Furthermore, in the third working mode, the preset flushing pump 1 can pump flushing liquid to the interventional pump flushing channel and the arterial pressure measurement channel at the same time with the third target flushing volume, third rotation speed and third duration.

[0130] In the above embodiment, based on the specific structure of the flow path control electronic device 5, the control host can control the first clamping mechanism and the second clamping mechanism to perform corresponding clamping actions, and control the preset flushing pump to work in a corresponding working mode to meet different flushing requirements.

[0131] In a specific embodiment, Figure 4 As shown, the above-mentioned electric control pipeline clamping device includes a two-position three-way electric pinch valve 51, and the two-position three-way electric pinch valve 51 includes a first clamping mechanism and a second clamping mechanism. The two-position three-way electric pinch valve 51 can squeeze the arterial pressure measuring tube 3 and / or the flushing tube 4 by electric driving, so as to achieve the purpose of switching and adjusting the arterial pressure measuring tube 3 and / or the flushing tube 4. Only one two-position three-way electric pinch valve is required to realize the control of the flow path connection state, reduce the structural complexity and system stability of the flushing system, and is more suitable for medical scenarios.

[0132] In another specific embodiment, Figure 5 As shown, the above-mentioned electric control pipeline clamping device includes a first electric pinch valve 52 and a second electric pinch valve 53. The first electric pinch valve 52 includes a first clamping mechanism, and the second electric pinch valve 53 includes a second clamping mechanism. The first electric pinch valve 52 can squeeze the arterial pressure measuring tube 3 by electric driving to achieve the purpose of switching and adjusting the arterial pressure measuring tube 3; the second electric pinch valve 53 can squeeze the flushing tube 4 by electric driving to achieve the purpose of switching and adjusting the flushing tube 4. By switching the pipelines through the two electric pinch valves, the installation position of the pipelines is not restricted, and the flushing tube and the arterial pressure measuring tube are installed independently of each other, which is convenient for the arrangement of the flushing pipelines.

[0133] In some possible embodiments, the flow path control electronic device 5 includes a pipeline valve device, which is provided with a channel switching structure, and the input tube 2, the arterial pressure measuring tube 3 and the flushing tube 4 are connected through the pipeline valve device; optionally, the above-mentioned pipeline valve device is an electrically controlled pipeline valve device.

[0134] Then, controlling the flow path control electronic device to switch from the first working state to the preset working state in S201 may include: controlling the channel switching structure to switch from a position corresponding to the first working state to a preset position corresponding to the preset working state;

[0135] It is understandable that the channel switching structure corresponds to different positions in different working states. By adjusting the position of the channel switching structure, the switching of different working states can be achieved. Among them, when the channel switching structure is in a preset position, the first flow path is in a connected state, or the first flow path and the second flow path are both in a connected state.

[0136] The pipeline valve device may be a three-way valve.

[0137] Correspondingly, controlling the preset flushing pump in S201 to pump flushing fluid to the arterial pressure measurement channel in a preset working mode may include: controlling the preset flushing pump to pump flushing fluid to the arterial pressure measurement channel in a second working mode; or controlling the preset flushing pump to pump flushing fluid to the interventional pump flushing channel and the arterial pressure measurement channel in a third working mode.

[0138] Here, regarding how the control host controls the preset flushing pump 1 to be in different working modes to meet different flushing requirements, reference may be made to the above embodiments, which will not be repeated here.

[0139] By setting the above-mentioned pipeline valve device, the flow path connectivity state control can also be achieved, which can enrich the applicable scenarios of the equipment and supplement the clinical scenarios where the pinch valve is not applicable.

[0140] In some possible embodiments, Figure 6 As shown, the input tube 2 includes a first input tube 21 and a second input tube 22 corresponding to the liquid storage device, the liquid storage device stores flushing liquid, the first input tube 21 is connected to the arterial pressure measuring tube 3 to form a first flow path, and the second input tube 22 is connected to the flushing tube 4 to form a second flow path; the flow path control electronic device 5 includes a first electrically controlled valve 54 that controls the connection state of the first flow path, and a second electrically controlled valve 55 that controls the connection state of the second flow path; the preset flushing pump 1 includes a first flushing pump 11 and a second flushing pump 12, the first flushing pump 11 is arranged on the flushing tube 4, and the second flushing pump 12 is arranged on the arterial pressure measuring tube 3;

[0141] Then, the above S201 may include: when receiving the first flushing instruction information, opening the first electrically controlled valve 54, and controlling the second flushing pump 12 to pump flushing liquid to the arterial pressure measuring channel.

[0142] Alternatively, the above S201 may include: upon receiving the first flushing instruction information, opening the first electrically controlled valve 54 and the second electrically controlled valve 55, controlling the first flushing pump 11 to pump flushing fluid into the interventional pump flushing channel, and controlling the second flushing pump 12 to pump flushing fluid into the arterial pressure measurement channel.

[0143] Understandably, in Figure 6 In the structure of the flushing system shown, the first flow path and the second flow path are controlled by different electrically controlled valves for connection status, and the interventional pump flushing channel and the arterial pressure measurement channel are pumped with flushing liquid by different flushing pumps; thus, the control host can control the two channels separately, and when the arterial pressure measurement channel needs to be flushed, only the first electrically controlled valve 54 can be opened, and the second flushing pump 12 can be controlled to pump flushing liquid to the arterial pressure measurement channel. When the arterial pressure measurement channel and the interventional pump flushing channel need to be flushed at the same time, the first electrically controlled valve 54 and the second electrically controlled valve 55 are opened, the first flushing pump 11 is controlled to pump flushing liquid to the interventional pump flushing channel, and the second flushing pump 12 is controlled to pump flushing liquid to the arterial pressure measurement channel.

[0144] Such a design allows the flushing control of the arterial pressure measurement channel and the interventional pump flushing channel to be completely independent. By controlling the two pumps and the two valves separately, the flushing volume under different requirements can be achieved without considering the factor of the flushing fluid diversion in the arterial pressure measurement channel and the interventional pump flushing channel.

[0145] In some possible embodiments, Figure 7 As shown, the control method of the embodiment of the present application may also include:

[0146] S202: When receiving flushing termination instruction information corresponding to the arterial pressure measurement channel, controlling the flow path control electronic device to switch from the preset working state back to the first working state, and controlling the preset flushing pump to pump flushing fluid to the interventional pump flushing channel in the first working mode.

[0147] The flushing stop instruction information corresponding to the arterial pressure measurement channel is used to instruct to stop flushing the arterial pressure measurement channel. Similar to the first flushing instruction information, the flushing stop instruction information can be automatically generated by the control host or triggered when a preset condition is met, or it can be a manual operation detected by the control host. A specific embodiment is provided below.

[0148] In a specific embodiment, the control host starts timing from the moment when the flow path control electronic device 5 switches to the preset working state; when the timing meets the preset flushing time, a flushing stop instruction information is generated. Here, the preset flushing time means the time sufficient to press the blood that flows back into the arterial pressure measurement channel back into the human body. For example, the preset flushing time can be a few seconds. In this way, by generating a flushing stop instruction at a fixed time, the flushing liquid is automatically stopped from being perfused into the arterial pressure measurement channel, so that the flushing process is fully automated, which can avoid the serious consequences that may be caused by forgetting to turn off the flushing liquid by manual operation.

[0149] The flushing system of the embodiment of the present application can be used to flush the interventional pump flushing channel corresponding to the interventional pump. The interventional pump and the flushing system are both important components of the transcatheter ventricular assist system.

[0150] To further illustrate the control method of the flushing system of the embodiment of the present application, Figure 8 As shown, Figure 8 It is a structural schematic diagram of a transcatheter ventricular assist system provided in an embodiment of the present application. In some possible embodiments, the flushing tube 4 includes a first circulation tube 41 and a second circulation tube 42, and the interventional pump includes a driving catheter handle 6, which is provided with a flushing liquid inlet and a flushing liquid outlet; the first circulation tube 41 is connected to the flushing liquid inlet, and the second circulation tube 42 is connected to the flushing liquid outlet. The first circulation tube 41 and the second circulation tube 42 are connected to the input tube 2 through a connecting structure 43, the first circulation tube 41 is used to transport the flushing liquid to the flushing liquid inlet, and the second circulation tube 42 is used to circulate the flushing liquid flowing out of the flushing liquid outlet back to the connecting structure 43.

[0151] In this structure, when the flow path control device 5 controls the first flow path to be in a connected state, the first flushing pump 1 operates and delivers flushing liquid to the first circulation pipe 41, so that the first circulation pipe 41 delivers the flushing liquid from the flushing liquid inlet to the driving catheter handle 6, and then the flushing liquid flowing out of the flushing liquid outlet is circulated and delivered back to the connecting structure 43 through the second circulation pipe 42. Since the first circulation pipe 41 and the second circulation pipe 42 are connected by the connecting structure 43, the flushing liquid flowing out of the flushing liquid outlet can enter the first circulation pipe 41 again, so that the following can be formed: Figure 5 The circulation flow path is shown.

[0152] Furthermore, in order to better control the circulation flow path, such as Figure 8 As shown, the flushing system also includes a circulation pump 7, which is arranged in the first circulation pipe 41; Figure 8 The control method of the flushing system of the embodiment of the present application is further explained.

[0153] In some possible embodiments, the control method of the embodiment of the present application also includes: according to the corresponding working state of the flow path control electronic device 5, controlling the circulation pump 7 to pump the flushing liquid in the first circulation pipe 41 into the driving catheter handle 6 through the flushing liquid inlet.

[0154] In this way, the control host controls the operation of the circulation pump 7 to drive part of the flushing liquid in the catheter handle 6 to flow into the second circulation pipe 42 through the flushing liquid outlet, so that the flushing liquid in the second circulation pipe 42 is transported back to the connecting structure 43, forming a partial circulation of the second flow path. In this way, on the one hand, it can avoid pumping too much flushing liquid into the interventional pump flushing channel at one time, and it can also avoid the flushing liquid from accumulating and staying in the driving catheter handle 6, which affects the normal operation of the handle. Furthermore, the control host can adjust the flow rate of the flushing liquid in the circulating flow path by controlling the circulation pump 7 to ensure that the flow state of the circulating flow path meets actual needs.

[0155] In summary, a control method for a flushing system provided in an embodiment of the present application can control the flow path connectivity of the arterial pressure measuring channel and the interventional pump flushing channel by controlling the flow path control electronic device to switch between different working states, and controlling the preset flushing pump to pump flushing liquid in different working modes, thereby realizing switching flushing between different flow paths, while meeting the different flushing requirements faced by the arterial pressure measuring channel and the interventional pump flushing channel, and can automatically control the flushing of the arterial pressure measuring channel without manual operation, with a high degree of automation, achieving precise flushing effects, and avoiding errors that may be caused by human operation.
