[0001] The present application relates to the technical field of medical devices, and in particular to a contrast agent liquid circuit control system and a contrast agent liquid circuit control method. Background Art

[0002] Contrast agents play a vital role in vascular interventional surgery. They can enhance the visualization of tissues and blood vessels. In clinical applications, contrast agent injection techniques are crucial to image quality and patient safety. Therefore, in interventional surgery, how to use contrast agents correctly and in a standardized manner (such as the speed, force, and total amount of contrast agent injection) is the main problem faced by contrast agent injection. Accurate control of contrast agent injection will improve image quality and ensure patient safety; however, incorrect or inaccurate contrast agent injection may lead to a decrease in image quality and affect patient safety. It can be seen that how to improve the safety and quality of contrast agent injection is an important issue in contrast agent injection.

[0003] However, the inventors of this application discovered during the actual research and development process that: in the related art, the contrast injection device does not have relevant control parameters for contrast agent injection (such as flow rate or pressure parameters), and cannot perform controls such as flow rate and pressure during contrast agent injection.

In addition, most contrast injection devices can only control contrast agent injection alone, and cannot inject contrast agents together with other liquid medicines. Other liquid medicines need to be input by other devices. The contrast agent and other liquid medicines are input by two different devices respectively, which makes it difficult to synchronize the control parameters of contrast agent input and other liquid medicine input, making it difficult to precisely coordinate contrast agents and other liquid medicines.

[0029] The present application embodiment provides a contrast agent liquid circuit control system, please refer to Figure 1 , Figure 1 It is a structural schematic diagram of a contrast agent liquid circuit control system provided in an embodiment of the present application, wherein the contrast agent liquid circuit control system includes a contrast agent injection device 100, a drug solution dripping device 200, an infusion pipeline 300 and an input device 400, and the contrast agent injection device 100 and the drug solution dripping device 200 are respectively connected to the infusion pipeline 300.

[0030] The input device 400 is used to input contrast agent injection parameters and / or liquid infusion parameters. There are multiple ways to input contrast agent injection parameters through the input device 400, including, for example: ① In some embodiments, a display screen may be provided on the input device 400, and a touch input control for contrast agent injection parameters may be displayed on the display screen of the input device 400. Contrast agent injection parameters (such as contrast agent injection speed, contrast agent dosage, contrast agent injection time, etc.) may be input through the touch input control for contrast agent injection parameters on the display screen of the input device 400; ② In some embodiments, a physical input control for contrast agent injection parameters may be provided on the input device 400, and contrast agent injection parameters (such as contrast agent injection speed, contrast agent dosage, contrast agent injection time, etc.) may be input through the physical input control for contrast agent injection parameters on the input device 400. Among them, there are many ways to input the drug drip parameters through the input device 400, exemplarily including: ① In some embodiments, a display screen can be set on the input device 400, and a touch input control for the drug drip parameters can be displayed on the display screen of the input device 400. The drug drip parameters (such as the drug drip speed, etc.) can be input through the touch input control for the drug drip parameters on the display screen of the input device 400; ② In some embodiments, a physical input control for the drug drip parameters can be set on the input device 400. The drug drip parameters (such as the drug drip speed, etc.) can be input through the physical input control for the drug drip parameters on the input device 400.

[0031] The contrast agent injection device 100 is used to control the injection of contrast agent into the infusion line 300 according to contrast agent injection parameters.

[0032] The liquid medicine dripping device 200 is used to control the dripping of liquid medicine into the infusion line 300 according to the liquid medicine dripping parameters. The liquid medicine dripping device 200 can be used to drip other liquid medicines such as saline other than contrast agents, so that the contrast agent can be matched with other liquid medicines, avoiding the problem that contrast agent injection and other liquid medicine dripping need to be controlled separately, and improving the input matching precision of contrast agents and other liquid medicines.

[0033] Therefore, since the contrast agent injection device 100 and the liquid medicine dripping device 200 are respectively connected to the infusion line 300, the contrast agent injection device 100 controls the contrast agent injection into the infusion line 300, and the liquid medicine dripping device 200 controls the liquid medicine dripping into the infusion line 300, so that the contrast agent can be input in coordination with other liquid medicines, thereby improving the operational safety and convenience of the process of collecting medical images using contrast agents. The contrast agent injection parameters are input through the input device 400, so that the contrast agent injection device 100 can control the contrast agent injection into the infusion line 300 according to the contrast agent injection parameters, thereby accurately controlling the contrast agent injection, improving the flow control accuracy during the contrast agent delivery process, making the contrast agent distribution more uniform, and thus improving the quality of medical images. By inputting the drug dripping parameters through the input device 400, the drug dripping device 200 can control the drug dripping into the infusion pipeline 300 according to the drug dripping parameters, thereby accurately controlling the drug dripping, meeting the drug dripping requirements during the contrast agent injection process, and improving the operational safety and convenience of the process of collecting medical images using contrast agents.

[0034] In order to better understand the contrast agent liquid circuit control system provided in this embodiment, the liquid circuit control functions that can be realized by the contrast agent liquid circuit control system in this embodiment are introduced below, including contrast agent liquid circuit control and drug liquid circuit control, as follows:

[0035] (1) Contrast agent fluid circuit control. Contrast agent fluid circuit control can include contrast agent injection, contrast agent exhaust, and contrast agent supplementation.

[0036] (1.1) Contrast agent injection

[0037] In some embodiments, a contrast agent injection start control can be set on the input device 400 (the contrast agent injection start control can be a physical button or a screen button) to control the contrast agent injection process. For example, taking "the contrast agent injection parameters are the contrast agent injection speed and the contrast agent dosage" as an example, a contrast agent injection start control is set on the display screen of the input device 400. When contrast agent injection is required, the operator can input the contrast agent injection speed and the contrast agent dosage through the input device 400; then, click the contrast agent injection start control (such as the "start" button) of the input device 400. At this time, the contrast agent injection device 100 starts the injection according to the input. The contrast agent injection speed controls the contrast agent to be injected into the infusion line 300 until the contrast agent of the input contrast agent dosage is completely injected into the infusion line 300; or, the input device 400 or the contrast agent injection device 100 can first calculate the required contrast agent injection time according to the input contrast agent injection speed and contrast agent dosage, and the contrast agent injection device 100 controls the contrast agent injection into the infusion line 300 according to the input contrast agent injection speed until the cumulative injection time of the contrast agent is equal to the contrast agent injection time, so that the contrast agent injection device 100 can inject the contrast agent into the infusion line 300 according to the specified contrast agent dosage and contrast agent injection speed. In this way, the contrast agent injection device 100 can control the contrast agent injection into the infusion line 300 according to the contrast agent injection parameters, so that the contrast agent injection can be accurately controlled.

[0038] In some embodiments, the contrast agent injection process can be controlled by setting a contrast agent injection start control on the contrast agent injection device 100 (the contrast agent injection start control can be a physical button or a screen button). For example, taking "the contrast agent injection parameters are the contrast agent injection speed and the contrast agent dosage" as an example, the contrast agent injection device 100 is provided with a contrast agent injection physical control. When contrast agent injection is required, the operator inputs the contrast agent injection speed and the contrast agent dosage; then, the contrast agent injection physical control is pressed. At this time, the contrast agent injection device 100 controls the contrast agent injection into the infusion line 300 according to the input contrast agent injection speed. When contrast agent injection needs to be stopped, the operator presses the contrast agent injection physical control. At this time, the contrast agent injection device 100 will stop injecting contrast agent into the infusion line 300. In this way, the contrast agent injection device 100 can control the contrast agent injection into the infusion line 300 according to the contrast agent injection parameters, so that the contrast agent injection can be accurately controlled.

[0039] In some embodiments, before contrast agent injection begins, the contrast agent injection device 100 will also perform a fault detection on the contrast agent liquid circuit. The contrast agent liquid circuit fault detection includes but is not limited to at least one of an injection pressure detection, a syringe installation detection, and a syringe emptying detection. When a fault is detected in the contrast agent liquid circuit, the motor on the contrast agent injection device 100 for driving the syringe to move will not run; when the contrast agent liquid circuit fault is eliminated or it is detected that there is no fault in the contrast agent liquid circuit, the motor on the contrast agent injection device 100 for driving the syringe to move is started to The syringe is driven to start injection, thereby injecting the contrast agent into the infusion line 300; in this way, by detecting the injection pressure through the contrast agent injection device 100, it is possible to detect whether the injection pressure of the contrast agent liquid circuit is too high or too low, thereby improving the accuracy of flow and pressure control during the contrast agent delivery process and making the contrast agent distribution more uniform; by detecting whether the syringe is correctly installed through the contrast agent injection device 100, it is possible to ensure safe and correct injection of the contrast agent; by detecting the emptying of the syringe through the contrast agent injection device 100, it is possible to avoid the problem of bubbles in the syringe and improve the safety of contrast agent injection. In addition, in some embodiments, during the contrast agent injection process, the contrast agent injection device 100 can also perform fault detection on the contrast agent liquid circuit. When a fault is detected in the contrast agent liquid circuit, the contrast agent injection device 100 will stop injecting contrast agent into the infusion line 300. In this way, the flow rate and pressure control accuracy during the contrast agent delivery process can be improved, thereby improving the safety of contrast agent injection. After the fault in the contrast agent liquid circuit is eliminated, the contrast agent injection device 100 controls the contrast agent to continue to be injected into the infusion line 300.

[0040] (1.2) Contrast agent exhaust

[0041] In some embodiments, the contrast agent injection device 100 may be provided with an exhaust button (or the input device 400 may be provided with an exhaust button for the drug liquid circuit, which may be a physical button or a screen button). When the operator finds that there are bubbles in the syringe of the contrast agent injection device 100, the operator may press the exhaust button of the contrast agent injection device 100 (or press the exhaust button of the drug liquid circuit on the input device 400). At this time, the contrast agent injection device 100 enters the contrast agent exhaust process to detect whether the syringe of the contrast agent injection device 100 is installed normally; when it is detected that the syringe is installed normally, the contrast agent injection device 100 exhausts the syringe. When the bubbles in the syringe have been eliminated, the operator may release the exhaust button of the contrast agent injection device 100 (or release the exhaust button of the drug liquid circuit on the input device 400) to stop exhausting. At this time, the contrast agent injection device 100 stops exhausting the syringe; or until the exhaust volume of the syringe is greater than the preset exhaust volume upper limit, the contrast agent injection device 100 automatically stops exhausting the syringe.

[0042] In some embodiments, during the process of the contrast agent injection device 100 venting the syringe, the contrast agent injection device 100 may also be detected for abnormalities, wherein the abnormality detection includes but is not limited to at least one of a syringe falling off detection and a motor abnormality detection; in this way, it is possible to detect whether the injection has fallen off or whether the click is abnormal, so as to prepare in advance for the subsequent contrast agent injection and improve the efficiency of contrast agent injection; when an abnormality is detected in the contrast agent injection device 100, the contrast agent injection device 100 suspends venting the syringe and continues to vent the syringe after the abnormality of the contrast agent injection device 100 is eliminated.

[0043] (1.3) Contrast agent supplement

[0044] The contrast agent injection device 100 can also be used to replenish contrast agent. In some embodiments, contrast agent replenishment is performed manually, for example, a contrast agent replenishment button can be provided on the contrast agent injection device 100 (or the input device 400 can be provided with a contrast agent replenishment button, which can be a physical button or a screen button), and when contrast agent replenishment is needed, the operator can press the contrast agent replenishment button of the contrast agent injection device 100 (or press the contrast agent replenishment button on the input device 400), and the contrast agent injection device 100 will start replenishing contrast agent. The contrast agent replenishment button is pressed and held until the contrast agent is fully replenished, and the operator can release the contrast agent replenishment button of the contrast agent injection device 100 (or release the contrast agent replenishment button on the input device 400), thereby completing the replenishment of contrast agent.

[0045] In some embodiments, contrast agent replenishment can be performed automatically. For example, a contrast agent replenishment control can be set on the input device 400. When the contrast agent needs to be replenished, the operator can input the contrast agent dosage to be replenished on the input device 400 and touch the contrast agent replenishment control of the input device 400. The contrast agent injection device 100 can complete the contrast agent replenishment according to the input contrast agent dosage to be replenished.

[0046] (2) Liquid medicine circuit control: Liquid medicine circuit control can include liquid medicine dripping and liquid medicine exhaust.

[0047] (2.1) Liquid flow control

[0048] In some embodiments, the dripping process of the medicine can be controlled by a touch control set on the display screen of the input device 400. For example, taking "the medicine is normal saline as an example, and the medicine dripping parameter is the normal saline dripping speed" as an example, a medicine dripping start control and a medicine dripping stop control are set on the display screen of the input device 400. When normal saline dripping is required, the operator can input the normal saline dripping speed through the input device 400; then, click the medicine dripping start control (such as the "on" button), at which time, the medicine dripping device 200 controls the normal saline dripping into the infusion line 300 according to the input normal saline dripping speed; when the normal saline dripping needs to be stopped, the operator clicks the medicine dripping stop control (such as the "stop" button) on the display screen of the input device 400, at which time the medicine dripping device 200 will stop dripping normal saline into the infusion line 300. In this way, the drug solution dripping device 200 can control the drug solution to drip into the infusion pipeline 300 according to the drug solution dripping parameters, thereby accurately controlling the drug solution dripping.

[0049] In some embodiments, the process of dripping the liquid medicine can be controlled by physical controls provided on the liquid medicine dripping device 200 or the input device 400. For example, taking "the liquid medicine is saline and the liquid medicine dripping parameter is the saline dripping speed" as an example, the liquid medicine dripping device 200 is provided with a physical control for dripping the liquid medicine. When saline dripping is required, the operator can input the saline dripping speed through the input device 400; then, the physical control for dripping the liquid medicine of the liquid medicine dripping device 200 is pressed, and at this time, the liquid medicine dripping device 200 controls the saline dripping into the infusion line 300 according to the input saline dripping speed; when the saline dripping needs to be stopped, the operator releases the physical control for dripping the liquid medicine of the liquid medicine dripping device 200, and at this time, the liquid medicine dripping device 200 stops dripping saline into the infusion line 300. In this way, the liquid medicine dripping device 200 can control the liquid medicine dripping into the infusion line 300 according to the liquid medicine dripping parameter, so that the liquid medicine dripping can be accurately controlled.

[0050] (2.2) Liquid Exhaust

[0051] like Figure 2 As shown, in some embodiments, the contrast agent liquid circuit control system also includes a bubble detection device 500; the bubble detection device 500 is used to detect whether bubbles are generated in the infusion line 300 during the infusion of the drug solution, and to remove the bubbles in the infusion line 300 when bubbles are generated. This can avoid the problem of bubbles in the infusion line endangering patient safety and improve the safety of drug solution input.

[0052] In some embodiments, an exhaust button can be set on the bubble detection device 500. During the process of the drug dripping device 200 controlling the dripping of the drug into the infusion line 300, if the bubble detection device 500 detects that bubbles are generated in the infusion line 300 during the drug dripping process, the operator can long press the exhaust button on the bubble detection device 500 to remove the bubbles generated in the infusion line 300 due to the drug dripping; when the bubbles in the infusion line 300 have been removed, the operator can release the exhaust button on the bubble detection device 500 to stop exhausting, and the bubble detection device 500 stops exhausting the infusion line 300 at this time; or when the exhaust volume of the drug in the infusion line is greater than the preset exhaust volume upper limit, the bubble detection device 500 automatically stops exhausting the infusion line 300. For example, taking the drug solution as saline, when the drug solution dripping device 200 controls the dripping of saline into the infusion line 300, if the bubble detection device 500 detects the presence of bubbles in the infusion line 300, the operator can long press the exhaust button on the bubble detection device 500 to remove the bubbles in the infusion line 300 caused by the dripping of saline.

[0053] See also Figure 2 and Figure 3 , Figure 3 301 is a flow chart of a contrast agent liquid circuit control method provided in an embodiment of the present application. The contrast agent liquid circuit control method is implemented based on a contrast agent liquid circuit control system, and the contrast agent liquid circuit control method includes steps 301 to 303, wherein:

[0054] 301. Receive contrast agent injection parameters through an input device 400, and determine contrast agent injection time according to the contrast agent injection parameters, wherein the contrast agent injection parameters include contrast agent injection speed and contrast agent dosage.

[0055] like Figure 1 or Figure 2 As shown, the contrast medium liquid circuit control system includes a contrast medium injection device 100, a liquid medicine dripping device 200, an infusion pipeline 300 and an input device 400. The contrast medium injection device 100 and the liquid medicine dripping device 200 are respectively connected to the infusion pipeline 300. The input device 400 is used to input contrast medium injection parameters and / or liquid medicine dripping parameters. The contrast medium injection device 100 is used to control the injection of contrast medium into the infusion pipeline 300 according to the contrast medium injection parameters, and the liquid medicine dripping device 200 is used to control the dripping of liquid medicine into the infusion pipeline 300 according to the liquid medicine dripping parameters. Further, the system includes a bubble detection device 500; the bubble detection device 500 is used to detect whether bubbles are generated in the infusion pipeline 300 during the liquid medicine dripping process, and remove the bubbles in the infusion pipeline 300 when bubbles are generated.

[0056] In some embodiments, the contrast agent injection time can be calculated by the contrast agent injection device 100. At this time, in step 301, first, the contrast agent injection speed and contrast agent dosage are input through the input device 400; then, the contrast agent injection start control (such as the "start" button) of the input device 400 is clicked; then, the contrast agent injection device 100 can first calculate the required contrast agent injection time according to the input contrast agent injection speed and contrast agent dosage, and then the contrast agent injection device 100 controls the contrast agent to be injected into the infusion line 300 according to the input contrast agent injection speed until the cumulative injection time of the contrast agent is equal to the contrast agent injection time, so that the contrast agent injection device 100 can inject the contrast agent into the infusion line 300 according to the specified contrast agent dosage and contrast agent injection speed. In this way, the contrast agent injection device 100 can control the contrast agent to be injected into the infusion line 300 according to the contrast agent injection parameters, so that the contrast agent injection can be accurately controlled.

[0057] In some embodiments, the contrast agent injection time can be calculated through the input device 400. In this case, in step 301, first, the contrast agent injection speed and contrast agent dosage are input through the input device 400; then, the contrast agent injection start control (such as the "start" button) of the input device 400 is clicked; then, the input device 400 can first calculate the required contrast agent injection time according to the input contrast agent injection speed and contrast agent dosage, and the contrast agent injection device 100 controls the contrast agent injection into the infusion line 300 according to the input contrast agent injection speed until the cumulative injection time of the contrast agent is equal to the contrast agent injection time, so that the contrast agent injection device 100 can inject the contrast agent into the infusion line 300 according to the specified contrast agent dosage and contrast agent injection speed. In this way, the contrast agent injection device 100 can control the contrast agent injection into the infusion line 300 according to the contrast agent injection parameters, so that the contrast agent injection can be accurately controlled.

[0058] 302 . In response to the contrast agent injection start instruction, the contrast agent injection device 100 performs contrast agent fluid path fault detection.

[0059] Wherein, the contrast agent liquid circuit fault detection includes at least one of injection pressure detection, syringe installation detection, and syringe emptying detection.

[0060] In some embodiments, a contrast agent injection start control can be set on the input device 400 (the contrast agent injection start control can be a physical button or a screen button) to trigger a contrast agent injection start instruction to control the contrast agent injection process. For example, taking "contrast agent injection parameters are contrast agent injection speed and contrast agent dosage" as an example, a contrast agent injection start control is set on the display screen of the input device 400. When contrast agent injection is required, the operator can input the contrast agent injection speed and contrast agent dosage through the input device 400; then, click the contrast agent injection start control of the input device 400 (such as the "Start" button), and the contrast agent injection start instruction will be triggered.

[0061] In some embodiments, a contrast agent injection start control can be set on the contrast agent injection device 100 (the contrast agent injection start control can be a physical button or a screen button) to trigger a contrast agent injection start instruction to control the contrast agent injection process. For example, taking "the contrast agent injection parameters are the contrast agent injection speed and the contrast agent dose" as an example, the contrast agent injection device 100 is provided with a contrast agent injection physical control. When contrast agent injection is required, the operator inputs the contrast agent injection speed and the contrast agent dose; then, the contrast agent injection physical control is pressed, and at this time, the contrast agent injection start instruction will be triggered.

[0062] Please refer to Figure 4 Before contrast agent injection begins, the contrast agent injection device 100 will perform a fault detection on the contrast agent liquid circuit. The contrast agent liquid circuit fault detection includes but is not limited to at least one of an injection pressure detection, a syringe installation detection, and a syringe emptying detection. When a fault is detected in the contrast agent liquid circuit, the motor on the contrast agent injection device 100 for driving the syringe to move will not run; when the contrast agent liquid circuit fault is eliminated or it is detected that there is no fault in the contrast agent liquid circuit, the motor on the contrast agent injection device 100 for driving the syringe to move is started to drive the injection. The contrast agent injection device 100 starts to inject, thereby injecting the contrast agent into the infusion line 300; in this way, by detecting the injection pressure through the contrast agent injection device 100, it is possible to detect whether the injection pressure of the contrast agent liquid circuit is too high or too low, thereby improving the accuracy of flow and pressure control during the contrast agent delivery process and making the contrast agent distribution more uniform; by detecting whether the syringe is correctly installed through the contrast agent injection device 100, it is possible to ensure that the contrast agent is injected safely and correctly; by detecting the emptying of the syringe through the contrast agent injection device 100, it is possible to avoid the problem of bubbles in the syringe and improve the safety of contrast agent injection.

[0063] 303. When it is detected that there is no fault in the contrast agent liquid circuit, contrast agent injection is started, and contrast agent injection is controlled into the infusion pipeline 300 by the contrast agent injection device 100 according to the contrast agent injection time.

[0064] For example, taking "the contrast agent injection parameters are the contrast agent injection speed and the contrast agent dosage" as an example, a contrast agent injection start control is provided on the display screen of the input device 400. When contrast agent injection is required, the operator can input the contrast agent injection speed and the contrast agent dosage through the input device 400; then, click the contrast agent injection start control (such as the "start" button) of the input device 400. When it is detected that there is no fault in the contrast agent liquid circuit, the contrast agent injection device 100 controls the contrast agent injection into the infusion pipeline 300 according to the input contrast agent injection speed until the cumulative injection time of the contrast agent is equal to the contrast agent injection time, so that the contrast agent injection device 100 can inject the contrast agent into the infusion pipeline 300 according to the specified contrast agent dosage and contrast agent injection speed. In this way, the contrast agent injection device 100 can control the contrast agent injection into the infusion pipeline 300 according to the contrast agent injection parameters, so that the contrast agent injection can be accurately controlled.

[0065] When a fault in the contrast agent fluid circuit is detected, contrast agent injection will not be started, and the motor on the contrast agent injection device 100 for driving the syringe to move will not run. When the fault in the contrast agent fluid circuit is eliminated, the motor on the contrast agent injection device 100 for driving the syringe to move is started to drive the syringe to start injection, thereby injecting the contrast agent into the infusion pipeline 300.

[0066] In some embodiments, during the contrast agent injection process, the contrast agent injection device 100 may also perform fault detection on the contrast agent liquid circuit. When a fault is detected in the contrast agent liquid circuit during the contrast agent injection process, the contrast agent injection device 100 controls the contrast agent injection to be suspended; after the fault is eliminated in the contrast agent liquid circuit, the contrast agent injection device 100 controls the contrast agent to continue to be injected into the infusion pipeline 300. When no fault is detected in the contrast agent liquid circuit during the contrast agent injection process, the contrast agent injection is continued.

[0067] In some embodiments, when there is a fault in the contrast medium liquid circuit that the syringe gas is not emptied, the contrast medium will be exhausted. During the contrast medium exhaust process, it is also detected whether the syringe of the contrast medium injection device 100 is installed normally; when it is detected that the syringe is installed normally, exhaust is started and the syringe is exhausted by the contrast medium injection device 100 until the exhaust volume of the syringe is greater than the preset exhaust volume upper limit. When it is detected that the syringe is installed abnormally, exhaust is not started, and exhaust is started after the syringe installation abnormality is eliminated. For example, the contrast agent injection device 100 may be provided with an exhaust button (or the input device 400 may be provided with an exhaust button for the drug liquid circuit, and the exhaust button may be a physical button or a screen button). When the operator finds that there are bubbles in the syringe of the contrast agent injection device 100, the operator may press the exhaust button of the contrast agent injection device 100 (or press the exhaust button of the drug liquid circuit on the input device 400). At this time, the contrast agent injection device 100 enters the contrast agent exhaust process to detect whether the syringe of the contrast agent injection device 100 is installed normally; when it is detected that the syringe is installed normally, the contrast agent injection device 100 exhausts the syringe. When the bubbles in the syringe have been eliminated, the operator may release the exhaust button of the contrast agent injection device 100 (or release the exhaust button of the drug liquid circuit on the input device 400) to stop exhausting. At this time, the contrast agent injection device 100 stops exhausting the syringe; or until the exhaust volume of the syringe is greater than the preset exhaust volume upper limit, the contrast agent injection device 100 automatically stops exhausting the syringe.

[0068] Please refer to Figure 5 In some embodiments, during the process of the contrast agent injection device 100 venting the syringe, the contrast agent injection device 100 may also be subjected to abnormality detection, wherein the abnormality detection includes but is not limited to at least one of the syringe detachment detection and the motor abnormality detection; in this way, it is possible to detect whether the syringe detaches or whether the click is abnormal, so as to prepare for the subsequent contrast agent injection in advance and improve the contrast agent injection efficiency; when an abnormality is detected in the contrast agent injection device 100, the contrast agent injection device 100 suspends venting the syringe, and continues to vent the syringe after eliminating the abnormality of the contrast agent injection device 100. When it is detected that there is no abnormality in the contrast agent injection device 100, the syringe continues to be vented.

[0069] Please refer to Figure 6Furthermore, the contrast agent liquid circuit control method may further include: receiving a contrast agent supplement dose through the input device 400; and in response to the contrast agent supplement instruction, supplementing the contrast agent according to the contrast agent supplement dose through the contrast agent injection device 100. In some embodiments, the contrast agent supplement instruction may be triggered by a contrast agent supplement control provided on the input device 400. When the contrast agent needs to be supplemented, the operator may input the contrast agent dose to be supplemented on the input device 400 and touch the contrast agent supplement control of the input device 400. The contrast agent injection device 100 may complete the supplement of the contrast agent according to the input contrast agent dose to be supplemented. In some embodiments, the contrast agent replenishment instruction can be triggered by a contrast agent refill button provided on the contrast agent injection device 100 (the refill button can be a physical button or a screen button). When the contrast agent needs to be replenished, the operator can press the contrast agent refill button of the contrast agent injection device 100, and the contrast agent injection device 100 will start to replenish the contrast agent. The contrast agent refill button is long pressed until the contrast agent is full, and the operator can release the contrast agent refill button of the contrast agent injection device 100 to complete the replenishment of the contrast agent.

[0070] For further information, please refer to Figure 7 The contrast agent liquid path control method may further include the following steps A1 to A3:

[0071] A1. Receive the drug solution dripping speed through the input device 400.

[0072] A2. In response to the liquid medicine drip start instruction, the bubble detection device 500 performs liquid medicine path fault detection.

[0073] Wherein, the liquid path fault detection of the liquid medicine includes at least one of bubble detection and liquid path pressure detection.

[0074] In some embodiments, a medicine drip start control can be set on the input device 400 (the medicine drip start control can be a physical button or a screen button) to trigger the medicine drip start instruction to control the medicine drip process. For example, taking "the medicine is normal saline as an example, and the medicine drip parameter is the normal saline drip speed" as an example, a medicine drip start control and a medicine drip stop control are set on the display screen of the input device 400. When normal saline drip is required, the operator can input the normal saline drip speed through the input device 400; then, click the medicine drip start control (such as the "on" button), and the medicine drip start instruction will be triggered.

[0075] In some embodiments, a drug drip start control can be set on the drug drip device 200 (the drug drip start control can be a physical button or a screen button) to trigger a drug drip start instruction to control the injection process of the contrast agent. For example, taking "the drug is normal saline as an example, and the drug drip parameter is the normal saline drip speed" as an example, a physical drug drip control is set on the drug drip device 200. When drug drip is required, the operator inputs the normal saline drip speed; then, the physical drug drip control is pressed, and the drug drip start instruction will be triggered.

[0076] During the infusion process of the medicinal solution, the medicinal solution dripping device 200 will perform fault detection on the medicinal solution liquid circuit. The medicinal solution liquid circuit fault detection includes but is not limited to at least one of bubble detection and liquid circuit pressure detection. When a fault is detected in the medicinal solution liquid circuit, the motor on the medicinal solution dripping device 200 for driving the dripper to move will not run; when the fault in the medicinal solution liquid circuit is eliminated, the motor on the medicinal solution dripping device 200 for driving the dripper to move is started to drive the dripper to start dripping, thereby dripping the medicinal solution into the infusion line 300; in this way, by detecting the dripping pressure through the medicinal solution dripping device 200, it is possible to detect whether the dripping pressure of the medicinal solution liquid circuit is too high or too low; by detecting the bubbles in the medicinal solution liquid circuit through the medicinal solution dripping device 200, it is possible to eliminate the bubbles generated in the infusion line 300 due to the dripping of physiological saline, thereby improving the safety of the medicinal solution dripping.

[0077] A3. When it is detected that there is no fault in the drug liquid circuit, the drug liquid dripping is started, and the drug liquid dripping device 200 controls the drug liquid to drip into the infusion pipeline 300 according to the drug liquid dripping speed.

[0078] For example, taking "the drug solution is saline solution, and the drug solution dripping parameter is the saline solution dripping speed" as an example, the input device 400 is provided with a drug solution dripping physical control. When saline solution dripping is required, the operator can input the saline solution dripping speed through the input device 400; then, the operator presses the drug solution dripping physical control of the input device 400, and at this time, the drug solution dripping device 200 controls the saline solution dripping into the infusion line 300 according to the input saline solution dripping speed; when the saline solution dripping needs to be stopped, the operator releases the drug solution dripping physical control of the input device 400, and at this time, the drug solution dripping device 200 will stop dripping saline solution into the infusion line 300. In this way, the drug solution dripping device 200 can control the drug solution dripping into the infusion line 300 according to the drug solution dripping parameter, so as to accurately control the drug solution dripping, meet the drug solution dripping requirements during contrast agent injection, and improve the operational safety and convenience of the process of collecting medical images using contrast agents. In this way, the contrast agent can be combined with other liquid medicines, avoiding the problem of separate and independent control of contrast agent injection and other liquid medicine infusion, and improving the input coordination precision of contrast agent and other liquid medicines.

[0079] When a fault is detected in the liquid medicine circuit, the liquid medicine dripping is not started. After the fault is eliminated in the liquid medicine circuit, the liquid medicine dripping is started again, and the liquid medicine dripping device 200 controls the liquid medicine dripping into the infusion line according to the liquid medicine dripping speed.

[0080] Furthermore, during the drug dripping process, the drug liquid circuit fault detection can also be continued; when a fault is detected in the drug liquid circuit, the drug address is suspended, and the drug dripping is continued after the fault is eliminated in the drug liquid circuit.

[0081] Furthermore, during the injection of the contrast agent, the dripping of the liquid medicine into the infusion line 300 can also be stopped. In response to the liquid medicine dripping stop instruction, the liquid medicine dripping device 200 controls the liquid medicine to stop dripping into the infusion line 300. In some embodiments, the liquid medicine dripping device 200 is provided with a physical control for liquid medicine dripping. Pressing the physical control for liquid medicine dripping on the liquid medicine dripping device 200 triggers the liquid medicine dripping start instruction, and releasing the physical control for liquid medicine dripping on the liquid medicine dripping device 200 triggers the liquid medicine dripping stop instruction. In some embodiments, the input device 400 is provided with a physical control for liquid medicine dripping. Pressing the physical control for liquid medicine dripping on the input device 400 triggers the liquid medicine dripping start instruction, and releasing the physical control for liquid medicine dripping on the input device 400 triggers the liquid medicine dripping stop instruction. In some embodiments, a liquid medicine drip start control (the start control may be a physical button or a screen button) and a liquid medicine drip stop control (the stop control may be a physical button or a screen button) are provided on the input device 400. Pressing the liquid medicine drip start control on the input device 400 triggers the liquid medicine drip start instruction, and pressing the liquid medicine drip stop control on the input device 400 triggers the liquid medicine drip stop instruction. When it is detected that there are no bubbles in the infusion line during the liquid medicine drip process, the liquid medicine drip is continued.

[0082] Please refer to Figure 8 Furthermore, during the infusion of the drug solution, the bubble detection device 500 can be used to detect whether there are bubbles in the infusion pipeline 300. When bubbles are detected in the infusion pipeline 300 during the infusion of the drug solution, in response to the touch operation of the exhaust button of the bubble detection device 500, the infusion pipeline 300 is exhausted by the bubble detection device 500; in response to the release operation of the exhaust button, the bubble detection device 500 stops exhausting the infusion pipeline 300; or until the exhaust volume of the drug solution in the infusion pipeline 300 is greater than the preset exhaust volume upper limit, the bubble detection device 500 stops exhausting the infusion pipeline 300.

[0083] From the above content, it can be seen that the contrast agent injection parameters are received through the input device, and the contrast agent injection time is determined according to the contrast agent injection parameters. The contrast agent injection into the infusion line is controlled according to the contrast agent injection time through the contrast agent injection device. The contrast agent injection into the infusion line 300 can be controlled according to the contrast agent injection parameters, so that the contrast agent injection can be accurately controlled, the flow control accuracy during the contrast agent delivery process is improved, and the contrast agent distribution is made more uniform, thereby improving the quality of medical images.
