[0074] Nutritional delivery equipment such as nutrient pumps can be used to deliver fluids such as nutrient solutions. During the process of delivering fluids, the delivery tube may be blocked due to solidification of the fluid. In order to ensure the stable operation of the nutrient delivery equipment, it is necessary to monitor the condition of the fluid in the delivery tube and flush the delivery tube through a flushing device.

[0075] Currently, a method for solving the problem of blockage in nutrition delivery equipment is to inject flushing liquid into the delivery tube in a fixed time and quantity through a flushing device, but this method is inefficient and cannot effectively solve the problem of blockage in nutrition delivery equipment.

[0076] The flushing control method proposed in the present application can be applied to nutrition delivery equipment. When the nutrient solution flows and is delivered in the delivery pipe, the flow condition of the fluid in the delivery pipe can be detected by the fluid detection component of the nutrition delivery equipment, and specifically, whether the fluid in the delivery pipe is blocked can be detected. The controller stores preset flushing rules corresponding to various flow conditions of the fluid in the delivery pipe. When the fluid in the delivery pipe is blocked, the controller can control the driving actuator to deliver flushing liquid into the delivery pipe. The flushing liquid can flush the blocked part in the delivery pipe during the flow of the flushing liquid in the delivery pipe, thereby achieving the purpose of relieving the blockage of the delivery pipe.

[0077] When a blockage occurs in the delivery pipe, the controller controls the driving actuator to deliver flushing liquid into the delivery pipe. In this way, flushing liquid can be delivered into the delivery pipe in a fast response when a blockage occurs in the delivery pipe, thereby efficiently handling the blockage of the delivery pipe.

[0078] The flushing control method and nutrient delivery device provided by the present application are described in detail below in conjunction with specific embodiments.

[0079] The embodiment of the present application provides a nutrition delivery device, which includes a housing 100 , a delivery tube 200 , a driving member 300 , a driving actuator 400 , a fluid detection member 500 and a controller 600 .

[0080] Among them, the shell 100 is the basic component of the nutrition delivery device of the present application. The shell 100 can provide an installation basis for at least some of the other components of the nutrition delivery device of the present application, and play the purpose of protecting at least some of the other components of the nutrition delivery device. The shell 100 can be made of metal or composite materials. The shell 100 made of metal has better structural strength, and the heat generated by the components in the shell 100 is also easier to be discharged outward through the shell 100; and the shell 100 is made of composite materials, which makes the weight of the shell 100 relatively light, and thus makes the overall weight of the nutrition delivery device of the present application relatively light. In the embodiment of the present application, there is no limitation on the specific material of the shell 100.

[0081] The housing 100 is provided with a mounting position, which can be used to place the delivery tube 200. A cavity can be provided in the housing 100, and the mounting position can be located in the cavity. Therefore, when the delivery tube 200 is placed on the mounting position, at least part of the delivery tube 200 is located in the housing 100. Specifically, the mounting position can be a groove opened in the cavity of the housing 100, and the groove cooperates with the delivery tube 200, so that the delivery tube 200 can be embedded in the groove, so that the delivery tube 200 can remain stable when it is located on the mounting position. Of course, the mounting position can also be set on the surface of the housing 100, so that when the delivery tube 200 is placed on the mounting position, the delivery tube 200 is located on the surface of the housing 100.

[0082] The driving member 300 is also disposed in the shell 100. Specifically, the driving member 300 can be disposed in the shell 100. The driving actuator 400 is connected to the driving member, and the driving actuator cooperates with the delivery pipe 200. The driving member 300 drives the driving actuator 400 to pump the fluid in the delivery pipe 200, so that the liquid in the delivery pipe 200 flows from one end of the delivery pipe 200 to the other end.

[0083] The fluid detection component 400 is disposed in the housing 100 . When the delivery tube 200 is placed on the installation position of the housing 100 , the fluid detection component 400 can detect the pressure in the delivery tube 200 or the flow rate of the fluid.

[0084] The controller 600 is connected to both the driving member 300 and the fluid detection member 400. The controller 600 can control the driving member 300 to open so that the driving member 300 can transport the fluid in the delivery tube 200. Specifically, after the delivery tube 200 is installed in the installation position and the fluid begins to flow in the delivery tube 200, the fluid detection member 400 can detect the flow of the fluid in the delivery tube 200. The fluid can be a nutrient solution, which may cause the delivery tube 200 to be blocked due to solidification when flowing in the delivery tube 200. When the fluid detection member 400 detects that a blockage has occurred in the delivery tube 200, the controller 600 can control the driving actuator 400 to transport a flushing liquid into the delivery tube 200 according to a preset flushing rule. When the flushing liquid flows in the delivery tube 200, it can flush the blocked part of the delivery tube 200 to achieve the purpose of solving the blockage of the delivery tube 200. It should be understood that the blockage in the delivery pipe 200 specifically means that the flow of the fluid in the delivery pipe 200 is affected. For example, if the delivery pipe 200 is completely blocked, resulting in the fluid in the delivery pipe 200 being unable to flow, or if the delivery pipe 200 is partially blocked, resulting in a decrease in the flow rate of the fluid in the delivery pipe 200, the delivery pipe is considered to be in a blocked state.

[0085] In some embodiments, the delivery pipe 200 of the present application may specifically include a first input end 210, a second input end 220, a confluence port 230, and an output end 240, wherein the first input end 210 and the second input end 220 may be disposed on the same side of the delivery pipe 200, and the output end 240 may be disposed on the other side of the delivery pipe 200. The confluence port 230 is located between the first input end 210 and the output end 240, and is also located between the second input end 220 and the output end 240. The confluence port 230 is simultaneously connected to the first input end 210, the second input end 220, and the output end 240. The first input end 210 is configured to be connectable or disconnectable with the confluence port 230, and the second input end 220 is also configured to be connectable or disconnectable with the confluence port 230. The driving actuator 400 may be disposed on the pipeline path of the delivery pipe 200, and the driving actuator 400 is located between the confluence port 230 and the output end 240. Therefore, when the first input end 210 is connected to the confluence port 230, the driving actuator 400 can drive the fluid to pass through the first input end 210, the confluence port 230 and the output end 240 in sequence; when the second input end 220 is connected to the confluence port 230, the driving actuator 400 can drive the fluid to pass through the second input end 220, the confluence port 230 and the output end 240 in sequence.

[0086] Specifically, the first input end 210 may be configured to communicate with a container loaded with nutrient solution, and the second input end 220 may be configured to communicate with a container loaded with flushing solution. When the delivery tube 200 is in a normal and unblocked state, the first input end 210 may be configured to communicate with the confluence port 230, so that the driving actuator 400 may drive the nutrient solution to be delivered in the delivery tube 200 and discharged through the output end 240, and the output end 240 may be connected to the patient. When the delivery tube 200 is in a blocked state, the second input end 220 may be configured to communicate with the confluence port 230, so that the driving actuator 400 may drive the flushing solution to be delivered in the delivery tube 200 and discharged through the output end 240.

[0087] In the present application, a three-way valve 800 may be provided at the confluence port 230 of the delivery pipe 200, and the first input end 210, the second input end 220 and the output end 240 of the delivery pipe 200 may be respectively connected to the three valve ports of the three-way valve 800. The driving member 300 may be a motor, and the driving actuator 400 may be a rolling wheel structure. The motor may drive the rolling wheel to rotate, and the delivery pipe 200 may be sleeved on the rolling wheel. When the rolling wheel rotates, the delivery pipe 200 may be squeezed, so that the fluid flows in the delivery pipe 200. The three-way valve 800 may be a solenoid valve structure, and the three-way valve 800 is electrically connected to the controller 600, so that the controller 600 may control the opening and closing of the valve ports in the three-way valve 800 connected to the first input end 210 and the second input end 220, and the valve port in the three-way valve 800 connected to the output end 240 may always be in an open state. When the nutrient delivery device is in a normal state of delivering nutrient solution, the controller 600 can control the valve port in the three-way valve 800 connected to the first input end 210 to open. At this time, the controller 600 controls the output end of the driving member 300 to rotate, which can cause the driving actuator 400 to rotate. In this way, the driving actuator 400 can squeeze the delivery tube 200, so that the nutrient solution flows in the delivery tube 200 and flows out from the output end 240.

[0088] When the nutrition delivery device is in a blocked state, the controller 600 can control the valve port in the three-way valve 800 connected to the second input end 220 to open. At this time, the controller 600 controls the output end of the driving member 300 to rotate, which can cause the driving actuator 400 to rotate. In this way, the driving actuator 400 can squeeze the delivery tube 200, so that the flushing liquid flows in the delivery tube 200 and flows out from the output end 240. In this process, the flushing liquid can flush the blocked part in the delivery tube 200.

[0089] In some embodiments, the fluid detection member 500 of the present application may specifically include a first sensor and / or a second sensor, wherein both the first sensor and the second sensor may be used to detect the flow of the fluid in the delivery tube 200. The first sensor may be disposed between the confluence port 230 of the delivery tube 200 and the portion where the driving actuator 400 contacts the delivery tube 200, and the second sensor may be disposed between the output end 240 of the delivery tube 200 and the portion where the driving actuator 400 contacts the delivery tube 200. When the first sensor and the second sensor exist at the same time, the first sensor and the second sensor may simultaneously detect the flow of the fluid in the delivery tube 200, so that the fluid detection member 500 can detect the flow of the fluid in the delivery tube 200 more accurately. Of course, only the first sensor and the second sensor may be disposed separately, thereby reducing the preparation cost of the nutrition delivery device of the present application.

[0090] The first sensor may be a flow rate sensor, and the second sensor may also be a flow rate sensor, which can detect the flow rate of the fluid in the delivery tube 200. When the delivery tube 200 is blocked, the nutrient solution cannot flow in the delivery tube 200, or the flow rate of the nutrient solution in the delivery tube 200 will be significantly reduced. In this way, whether the flow rate sensor is set between the confluence 230 of the delivery tube 200 and the contact portion of the driving actuator 400 and the delivery tube 200, or between the output end 240 of the delivery tube 200 and the contact portion of the driving actuator 400 and the delivery tube 200, the flow rate sensor can detect the reduction in the flow rate of the fluid in the delivery tube 200, thereby determining that the delivery tube 200 is in a blocked state.

[0091] The second sensor can also be a pressure sensor. When a blockage occurs in the tube portion between the driving actuator 400 and the output end 240 of the delivery tube 200, the driving actuator 400 cannot discharge all the nutrient solution on the delivery tube 200 between the driving actuator 400 and the output end 240 of the delivery tube 200. The blocked portion of the delivery tube 200 causes the nutrient solution to be continuously replenished to the portion of the delivery tube 200 between the driving actuator 400 and the output end 240 of the delivery tube 200. In this way, the pressure sensor can detect the pressure increase in the delivery tube 200, thereby determining that the delivery tube 200 is in a blocked state.

[0092] In addition, in some embodiments, the first sensor may also be a dripping rate sensor. Specifically, the first input end 210 of the delivery tube 200 may be connected to a nutrient bag loaded with nutrient solution, and the dripping rate sensor may be disposed at the nutrient bag to detect the dripping rate of the nutrient solution in the nutrient bag. When the delivery tube 200 is blocked, the dripping rate detected by the dripping rate sensor will decrease accordingly.

[0093] refer to Figure 4 As shown, the embodiment of the present application also proposes a flushing control method, which can be applied to the above-mentioned nutrition delivery device. The method includes the following steps:

[0094] S100, obtaining the flow condition of the first fluid in the delivery tube. Specifically, during the feeding and infusion process of the nutrition delivery device, when the first input end 210 of the delivery tube 200 is in a connected state with the confluence port 230, and the first input end 210 is connected with the container loaded with the nutrient solution, the controller 600 controls the driving member 300 to start and then drives the actuator 400 to drive the nutrient solution in the delivery tube 200 to flow toward the output end 240 of the delivery tube 200. The fluid detection member 500 is configured to be connected to the delivery tube 200, so that the fluid detection member 500 can detect the flow condition of the nutrient solution in the delivery tube 200.

[0095] S200, according to the flow condition of the first fluid and the preset flushing rule, determine to trigger pipeline flushing, and control the driving actuator to deliver flushing liquid to the delivery pipe.

[0096] After the fluid detection component 500 detects the flow of the first fluid in the delivery pipe 200, the flow of the first fluid can be formed into data and transmitted to the controller 600, and the controller 600 stores a preset flushing rule. The preset flushing rule can correspond to the flow of the first fluid in the delivery pipe 200. When a blockage occurs in the delivery pipe 200, the controller 600 can trigger an instruction to flush the delivery pipe 200. The controller 600 can control the second input end 220 of the delivery pipe 200 to be connected to the confluence port 230. Specifically, it can be achieved by controlling the opening and closing of the valve port of the three-way valve 800, so that the delivery pipe 200 can be connected to the container loaded with flushing liquid. The controller 600 can control the driving actuator 400 to suck the flushing liquid in the container into the delivery pipe 200, and drive the flushing liquid to flow out from the output end 240 of the delivery pipe 200. The flushing liquid can flush the blocked part of the delivery pipe 200 during the flow in the delivery pipe 200, so as to achieve the purpose of relieving the blocked state of the delivery pipe 200.

[0097] In one embodiment, the preset flushing rule may be determined based on the correspondence between the first fluid flow condition and the flushing trigger condition. When the parameters of the first fluid flow condition meet the flushing trigger condition, the preset flushing rule determines to trigger flushing. For example, the first fluid flow condition includes a blocking pressure value, and the flushing trigger condition includes a blocking pressure threshold. When the blocking pressure value detected by the fluid detection component 500 is greater than or equal to the blocking pressure threshold, flushing is determined to be triggered. Of course, the above example is only one implementation of the present application, and different detection parameters or trigger conditions may also be used, which are not limited here one by one.

[0098] Of course, when the fluid detection component 500 detects that the first fluid in the delivery tube 200 is in a normal flow state, that is, when the fluid detection component 500 detects that the pressure in the delivery tube 200 and the flow rate of the first fluid are normal, the controller 600 can control the first input end 210 of the delivery tube 200 to remain connected with the conduit 230, and the controller 600 also controls the driving component 300 to operate normally to continuously deliver nutrient solution to the delivery tube 200.

[0099] In some embodiments, when the fluid detection component 500 is a pressure sensor, the flow condition of the fluid in the delivery tube 200 detected by the fluid detection component 500 is the blockage pressure information of the fluid in the delivery tube 200; when the fluid detection component 500 is a flow rate sensor, the flow condition of the fluid in the delivery tube 200 detected by the fluid detection component 500 is the flow rate information of the fluid in the delivery tube 200.

[0100] In some embodiments, reference Figure 5 As shown, step S200: according to the flow condition of the first fluid and the preset flushing rule, the flushing liquid is delivered into the delivery pipe 200, which may specifically include the following steps:

[0101] S210, determining flushing parameters according to the flow condition of the first fluid;

[0102] S220, delivering flushing liquid into the delivery pipe according to the flushing parameters.

[0103] Among them, a plurality of flushing parameters may be set in the controller 600, and the plurality of flushing parameters may correspond to a plurality of different first fluid flow conditions in the delivery pipe 200. The controller 600 may control the driving actuator 400 to deliver flushing liquid into the delivery pipe 200 through the flushing parameters corresponding to the first fluid flow conditions. Specifically, after determining the flow condition of the first fluid in the delivery pipe 200, the controller 600 may determine the flushing parameters corresponding to the flow condition according to the flow condition of the first fluid in the delivery pipe 200 at this time, and control the driving actuator 400 to deliver flushing liquid into the delivery pipe 200 with the flushing parameters. At this time, the flushing liquid flowing in the delivery pipe 200 may relatively fully flush the blocked part in the delivery pipe 200, so as to better relieve the blocked state of the delivery pipe 200.

[0104] In some embodiments, reference Figure 6 As shown, step S210: determining flushing parameters according to the flow condition of the first fluid, which may specifically include the following steps:

[0105] S211, determining a blocking condition of the delivery pipe according to a flow condition of the first fluid;

[0106] S212, determining flushing parameters according to the blockage condition of the delivery pipe.

[0107] When the first fluid flows in the delivery pipe 200 and causes a blockage in the delivery pipe 200, the delivery pipe 200 can be classified into different blockage conditions according to the severity of the blockage of the first fluid in the delivery pipe 200. Specifically, when the blockage in the delivery pipe 200 is relatively light, the delivery pipe 200 has one blockage condition, and when the blockage in the delivery pipe 200 is relatively heavy, the delivery pipe 200 has another blockage condition. When the blockage in the delivery pipe 200 is between relatively light and relatively heavy, the delivery pipe 200 also has one or more blockage conditions, and the degrees of these blockage conditions are different.

[0108] The various flushing parameters stored in the controller 600 correspond to the obstruction conditions of the delivery tube 200. Specifically, one flushing parameter can be set to correspond to one obstruction condition, or multiple flushing parameters can be set to correspond to one obstruction condition, or one flushing parameter can be set to correspond to multiple obstruction conditions. Specifically, when the obstruction condition in the delivery tube 200 is more serious, the controller 600 can control the driving actuator 400 to deliver flushing liquid to the delivery tube 200 with flushing parameters with more obvious flushing effects, so that the serious obstruction condition in the delivery tube 200 can be relieved. When the obstruction condition in the delivery tube 200 is lighter, the controller 600 can control the driving actuator 400 to deliver flushing liquid to the delivery tube 200 with flushing parameters with relatively small flushing effects, so that the serious obstruction condition in the delivery tube 200 can be relieved, and the purpose of reducing the amount of flushing liquid can be achieved. In this way, the flushing liquid delivered to the patient's body is relatively less, which can make the patient experience relatively better.

[0109] Specifically, the occlusion condition is related to at least one of an occlusion pressure value, a flow rate value, an occlusion pressure change amount, a flow rate change amount, an occlusion pressure change rate, and a flow rate change rate.

[0110] In some embodiments, when the fluid detection member 500 is a pressure sensor, the flow condition of the first fluid in the delivery tube 200 detected by the fluid detection member 500 is related to at least one of the blocking pressure value, blocking pressure change amount, and blocking pressure change rate in the delivery tube 200. Therefore, the blocking condition of the delivery tube 200 can be determined based on at least one of the blocking pressure value, blocking pressure change amount, and blocking pressure change rate in the delivery tube 200 detected by the fluid detection member 500.

[0111] When the pipe section between the driving actuator 400 and the output end 240 on the delivery pipe 200 is completely blocked, the first fluid is blocked in the pipe section between the driving actuator 400 and the output end 240 of the delivery pipe 200. At this time, even if the driving actuator 400 operates normally, the first fluid in the delivery pipe 200 cannot be discharged from the output end 240 of the delivery pipe 200, thereby causing the pressure of the pipe section between the driving actuator 400 and the output end 240 on the delivery pipe 200 to increase. At this time, the blocking pressure value of the delivery pipe 200 detected by the fluid detection component 500 increases accordingly, and as the pipe section between the driving actuator 400 and the output end 240 of the delivery pipe 200 on the delivery pipe 200 is completely blocked, the pressure of the pipe section in this area will rise to the highest value, and accordingly, the blocking pressure value detected by the fluid detection component 500 will also reach the highest value.

[0112] When the pipe portion between the driving actuator 400 and the output end 240 of the delivery pipe 200 is partially blocked, the first fluid can still pass through the blocked portion in the delivery pipe 200, but the flow rate of the first fluid passing through the blocked portion will be reduced, thereby reducing the flow rate of the first fluid in the delivery pipe 200. At this time, the blocking pressure value of the delivery pipe 200 detected by the fluid detection element 500 increases accordingly, but the blocking pressure value will not increase to the highest blocking pressure value when the delivery pipe 200 is completely blocked.

[0113] When there is no blockage in the delivery pipe 200 , the first fluid can pass through the delivery pipe 200 normally. At this time, the blockage pressure value of the delivery pipe 200 detected by the fluid detection element 500 can remain unchanged or float within a small range.

[0114] Specifically, the blocking condition of the delivery pipe 200 can be divided into a plurality of blocking levels, and the plurality of blocking levels can correspond to different blocking severity of the blocking pipe, that is, corresponding to different blocking pressure values ​​detected by the fluid detection member 500. The higher the blocking pressure value, the higher the blocking level, and the more serious the blocking condition. The lower the blocking pressure value, the lower the blocking level, and the lighter the blocking condition.

[0115] In addition, a fluid detection member 500 may be provided to detect the blocking pressure in the delivery pipe 200 in real time, and the change in the blocking pressure of the delivery pipe 200 within a preset time period may be obtained. When the change in the blocking pressure of the delivery pipe 200 is large, it may indicate that the blocking degree in the delivery pipe 200 is more serious, and thus may correspond to a higher blocking level. When the change in the blocking pressure of the delivery pipe 200 is relatively small, it may indicate that the blocking degree in the delivery pipe 200 is less severe, and thus may correspond to a lower blocking level. When the change in the blocking pressure of the delivery pipe 200 is zero or close to zero, it may indicate that no blocking occurs in the delivery pipe 200.

[0116] When the fluid detection member 500 detects the blocking pressure in the delivery pipe 200 in real time, it can also be set to obtain the blocking pressure change rate of the delivery pipe 200 within a preset time period. When the blocking pressure change rate of the delivery pipe 200 is large, it can indicate that the blocking degree in the delivery pipe 200 is more serious, which can correspond to a higher blocking level. When the blocking pressure change rate of the delivery pipe 200 is relatively small, it can indicate that the blocking degree in the delivery pipe 200 is lighter, which can correspond to a lower blocking level. When the blocking pressure change rate of the delivery pipe 200 is zero or close to zero, it can indicate that there is no blocking in the delivery pipe 200.

[0117] When the fluid detection member 500 uses a flow rate sensor, the flow condition of the first fluid in the delivery tube 200 detected by the fluid detection member 500 is related to the flow rate of the first fluid in the delivery tube 200. Therefore, the blockage condition of the delivery tube 200 can be determined according to the flow rate value in the delivery tube 200 detected by the fluid detection member 500.

[0118] Specifically, when a complete blockage occurs in the delivery pipe 200, the first fluid is blocked in the pipe portion between the inlet 230 of the delivery pipe 200 and the drive actuator 400, or is blocked in the pipe portion between the output end 240 of the delivery pipe 200 and the drive actuator 400. At this time, even if the drive actuator 400 operates normally, the first fluid in the delivery pipe 200 cannot flow. At this time, the flow rate value of the delivery pipe 200 detected by the fluid detection component 500 decreases accordingly, and as the first fluid in the delivery pipe 200 completely stops flowing, the flow rate of the first fluid in the delivery pipe 200 will drop to the minimum value, and accordingly, the flow rate value detected by the fluid detection component 500 will also reach the minimum.

[0119] When a partial blockage occurs in the delivery tube 200, the first fluid can still pass through the blocked portion in the delivery tube 200, but the flow rate of the first fluid passing through the blocked portion will be reduced, thereby reducing the flow rate of the first fluid in the delivery tube 200. At this time, the flow rate value of the delivery tube 200 detected by the fluid detection element 500 is reduced accordingly, but the flow rate value will not be reduced to the minimum flow rate value when the delivery tube 200 is completely blocked.

[0120] When there is no blockage in the delivery pipe 200 , the first fluid can pass through the delivery pipe 200 normally. At this time, the flow rate value of the delivery pipe 200 detected by the fluid detection element 500 can remain unchanged or float within a small range.

[0121] Specifically, the lower the flow rate value, the higher the blockage level and the more serious the blockage situation. The higher the flow rate value, the lower the blockage level and the lighter the blockage situation.

[0122] In addition, a fluid detection member 500 may be provided to detect the flow velocity of the first fluid in the delivery pipe 200 in real time, and the change in the flow velocity of the first fluid in the delivery pipe 200 within a preset time period may be obtained. When the change in the flow velocity of the delivery pipe 200 is large, it may indicate that the degree of obstruction in the delivery pipe 200 is relatively serious, and thus may correspond to a higher level of obstruction. When the change in the flow velocity of the delivery pipe 200 is relatively small, it may indicate that the degree of obstruction in the delivery pipe 200 is relatively light, and thus may correspond to a lower level of obstruction. When the change in the flow velocity of the delivery pipe 200 is zero or close to zero, it may indicate that no obstruction occurs in the delivery pipe 200.

[0123] When the fluid detection member 500 detects the flow velocity of the first fluid in the delivery pipe 200 in real time, it can also be set to obtain the flow velocity change rate of the delivery pipe 200 within a preset time period. When the flow velocity change rate of the delivery pipe 200 is large, it can indicate that the degree of blockage in the delivery pipe 200 is more serious, which can correspond to a higher blockage level. When the flow velocity change rate of the delivery pipe 200 is relatively small, it can indicate that the degree of blockage in the delivery pipe 200 is less, which can correspond to a lower blockage level. When the flow velocity change rate of the delivery pipe 200 is zero or close to zero, it can indicate that there is no blockage in the delivery pipe 200.

[0124] In some embodiments, the flushing parameters in the present application may specifically include at least one of the flushing liquid flow rate, flushing liquid volume, and flushing frequency. Among them, the flushing liquid flow rate refers to the flow rate of the flushing liquid driven by the driving actuator 400 to flow in the delivery tube 200. The flushing liquid volume refers to the flow rate of the flushing liquid driven by the driving actuator 400 to flow in the delivery tube 200. The flushing frequency refers to the frequency at which the driving actuator 400 drives the flushing liquid to flow in the delivery tube 200. Specifically, when the delivery tube 200 is blocked, the driving actuator 400 can drive the flushing liquid to flow in the delivery tube 200 at intervals for multiple times. The higher the flushing frequency, the more times the driving actuator 400 drives the flushing liquid to flow in the delivery tube 200 per unit time.

[0125] When the blocking condition of the delivery pipe 200 is more serious and the blocking level is higher, the controller 600 can be used to control the driving actuator 400 to deliver the flushing liquid to the delivery pipe 200 at a higher flushing liquid flow rate, a higher flushing liquid volume and a higher flushing frequency, so that the blocking of the delivery pipe 200 can be fully relieved. When the blocking condition of the delivery pipe 200 is lower and the blocking level is lower, the controller 600 can be used to control the driving actuator 400 to deliver the flushing liquid to the delivery pipe 200 at a lower flushing liquid flow rate, a lower flushing liquid volume and a lower flushing frequency, so that the blocking of the delivery pipe 200 can be fully relieved while reducing the amount of flushing liquid used.

[0126] In some embodiments, reference Figure 7 As shown, before step S210: determining the flushing parameters according to the flow condition of the first fluid, the flushing control method of the present application may further include the following steps:

[0127] S213, obtaining the transport pipe information.

[0128] Step S210: Determine flushing parameters according to the flow of the first fluid, which may specifically include the following steps:

[0129] S214, determining flushing parameters according to the flow condition of the first fluid and the delivery pipe information.

[0130] The information of the delivery tube 200 can be obtained through the delivery tube detection member 700, and the information of the delivery tube 200 may include the diameter and material of the delivery tube 200. The larger the diameter of the delivery tube 200, the smaller the impact on the flow of the first fluid in the delivery tube 200 when the delivery tube 200 is blocked, and the smaller the impact on the blocking pressure value and flow rate value detected by the fluid detection member 500. The smaller the diameter of the delivery tube 200, the greater the impact on the flow of the first fluid in the delivery tube 200 when the delivery tube 200 is blocked, and the greater the impact on the blocking pressure value and flow rate value detected by the fluid detection member 500.

[0131] The harder the material of the delivery tube 200 is, the less influence the flow of the first fluid in the delivery tube 200 will have when the delivery tube 200 is blocked, and the less influence the blockage pressure value and flow rate value detected by the fluid detection component 500 will have. The softer the material of the delivery tube 200 is, the greater the influence the flow of the first fluid in the delivery tube 200 will have when the delivery tube 200 is blocked, and the greater the influence the blockage pressure value and flow rate value detected by the fluid detection component 500 will have.

[0132] Therefore, the controller 600 can also determine the flushing parameters according to the information of the delivery tube 200 detected by the delivery tube detection member 700. When the diameter of the delivery tube 200 is larger, the flow rate of the flushing liquid can be controlled to be relatively larger, so that the flushing liquid can be filled in the delivery tube 200, the flow rate of the flushing liquid can be set faster, and the flushing frequency can be set higher. When the diameter of the delivery tube 200 is smaller, the flow rate of the flushing liquid can be controlled to be relatively smaller, so that the flushing liquid can be filled in the delivery tube 200, the flow rate of the flushing liquid can be set slower, and the flushing frequency can be set lower.

[0133] Specifically, the delivery information of the delivery tube 200 can be input into the controller 600 after manual measurement and identification by the user. Of course, a label storing parameter information of the delivery tube 200 can also be provided on the delivery tube 200, and an identification mechanism for reading the label information on the delivery tube 200 can be provided on the nutrition delivery equipment, so that the information of the delivery tube 200 can also be obtained.

[0134] In some embodiments, reference Figure 8 As shown, in step S200: according to the flow condition of the first fluid and the preset flushing rule, it is determined to trigger pipeline flushing, and the driving actuator is controlled to deliver flushing liquid to the delivery pipe. After that, the flushing control method of the present application also includes:

[0135] S300, obtaining the flow condition of the second fluid in the delivery pipe;

[0136] S310, determining a flushing adjustment strategy according to the flow condition of the second fluid and a preset parameter adjustment rule;

[0137] S320, controlling the controller to deliver flushing liquid to the delivery pipe according to the flushing adjustment strategy.

[0138] When the second fluid flows in the delivery pipe 200 , the fluid detection member 500 can detect the flow condition of the second fluid in the delivery pipe 200 .

[0139] When the second fluid flows in the delivery tube 200, the fluid detection member 500 detects that the delivery tube 200 is still in a blocked state, indicating that the flushing liquid has failed to flush out the obstruction in the blocked part of the delivery tube 200. The controller 600 stores a preset parameter adjustment rule, which corresponds to the flow of the second fluid. The controller 600 controls the driving member 300 to drive the driving actuator 400 to deliver the flushing liquid to the delivery tube 200 according to the flushing adjustment strategy, which can solve the blockage in the delivery tube 200 according to the flow of the second fluid.

[0140] Specifically, when the flow condition of the second fluid in the delivery tube 200 detected by the fluid detection member 500 is still a blocked condition, it means that the controller 600 cannot remove the blockage of the delivery tube 200 by delivering the flushing liquid into the delivery tube 200 according to the preset flushing rule. At this time, the controller 600 controls the delivery of the flushing liquid into the delivery tube 200 according to the flushing adjustment strategy to target the flow condition of the second fluid, thereby better removing the blockage in the delivery tube 200.

[0141] The second fluid flow condition may be an occlusion pressure value and / or a flow rate value, and the flushing adjustment strategy corresponds to adjusting at least one of a flushing liquid flow rate, a flushing liquid volume, and a flushing frequency.

[0142] In some embodiments, reference Fig. 9 As shown, in step S320: according to the flushing adjustment strategy, the controller 600 is controlled to deliver flushing liquid to the delivery pipe 200. After that, the flushing control method of the present application further includes the following steps:

[0143] S330, determining adjusted flushing parameters according to the flushing adjustment strategy;

[0144] S340, storing the adjusted flushing parameters and flushing parameter adjustment information;

[0145] The flushing parameter adjustment information includes the values ​​of the flushing parameters before and after adjustment.

[0146] When the flushing rule strategy is confirmed, it has the corresponding adjusted flushing parameters, and the controller 600 controls the driving actuator 400 to continue to deliver the flushing liquid to the delivery tube 200 with the flushing parameters. The controller 600 can store the adjusted flushing parameters. If the flushing parameters can solve the blockage of the delivery tube 200, then when the same blockage condition of the delivery tube 200 as before occurs again, the flushing liquid can be directly delivered to the delivery tube 200 with the adjusted flushing parameters, which can solve the blockage of the delivery tube 200 more efficiently. Furthermore, the controller can also store information such as the material, length and diameter of the delivery tube flushed this time, so as to associate the flushing parameters with the corresponding delivery tube information.

[0147] In addition, the controller 600 may also output the adjusted flushing parameters to other storage devices, such as a server, so that other nutrition delivery devices may also call the flushing parameters.

[0148] In some embodiments, reference Fig.10 As shown, in step S320: according to the flushing adjustment strategy, the controller is controlled to deliver flushing liquid to the delivery pipe. After that, the flushing control method of the present application further includes the following steps:

[0149] S350: Determine a fluid change parameter according to the flow condition of the first fluid and the flow condition of the second fluid;

[0150] S360: Output prompt information according to the fluid change parameters.

[0151] The function of the second fluid flowing in the delivery pipe 200 is to flush the blocked part in the delivery pipe 200, so the flow condition of the second fluid is different from the flow condition of the first fluid. By comparing the flow condition of the first fluid and the flow condition of the second fluid, the fluid change parameter of the fluid flowing in the delivery pipe 200 can be determined. A display structure and a sound structure can also be set on the nutrition delivery device, and the controller 600 can output prompt information of the fluid change parameter of the fluid in the delivery pipe 200 through the display device and the sound structure, so that the user can know whether the nutrition delivery device is in the state of delivering nutrient solution or delivering flushing liquid to flush the blocked state of the delivery pipe 200.

[0152] In some embodiments, reference Fig.11 As shown, in S200: according to the flow condition of the first fluid and the preset flushing rule, it is determined to trigger pipeline flushing, and the driving actuator is controlled to deliver flushing liquid to the delivery pipe. After that, the flushing control method of the present application also includes:

[0153] S400, obtaining the flow condition of the second fluid in the delivery pipe;

[0154] S500: If it is determined that the flow condition of the second fluid meets the preset feeding condition, the nutrient solution is delivered into the delivery tube.

[0155] Specifically, when the flow of the second fluid in the delivery tube 200 is normal, it means that the delivery tube 200 is in a normal state, and the nutrient solution can be normally delivered through the delivery tube 200. At this time, the controller 600 can control the first input end 210 of the delivery tube 200 to be connected with the confluence port 230, and the second input end 220 to be disconnected from the confluence port 230. At this time, the driving actuator 400 can drive the nutrient solution to flow in the delivery tube 200 and deliver it to the patient through the output end 240.

[0156] Specifically, if the process of the nutrition delivery device delivering the nutrient solution to the patient is not completed due to the blockage of the delivery tube 200, when the blockage of the delivery tube 200 is removed and the nutrient solution is delivered to the patient again through the delivery tube 200, the controller 600 can control the driving actuator 400 to continue the previously unfinished nutrient solution delivery process. Of course, the controller 600 can also control the driving actuator 400 to deliver the nutrient solution to the delivery tube 200 with a new nutrient solution delivery process, and this application does not limit this.

[0157] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation modes of the present application.
