[0046] Infusion devices can be used to deliver fluids such as liquid medicine and nutrient solution. During the process of delivering fluids, the delivery tube of the infusion device may be blocked or bubbles may appear. In order to ensure the stable operation of the infusion device, it is necessary to monitor the condition of the fluid in the delivery tube.

[0047] At present, the method of detecting whether the delivery pipe is blocked or has bubbles is to set up a blockage sensor and a bubble sensor for detection respectively. However, such a detection method requires a large number of sensors, is relatively complicated, and results in a relatively high preparation cost of the delivery pump.

[0048] In the infusion line detection method of the present application, a data acquisition device is arranged on the infusion line of the infusion equipment. When the infusion equipment is running, the data acquisition device can collect the state of fluid flow in the infusion line of the infusion equipment at different times and form data. By processing the data collected by the data acquisition device at different times, the infusion state of the infusion line can be determined, so as to determine whether the infusion line is in a normal state, a blocked state or a bubble state. The present application can realize the infusion line state detection function by collecting data on the fluid flow state in the infusion line multiple times through a data acquisition device, thereby reducing the number of data acquisition devices and reducing the types of data collected by the data acquisition device, thereby achieving the purpose of simplifying the structure of the infusion system.

[0049] The infusion line detection method, infusion system detection device and electronic equipment provided by the present application are described in detail below in conjunction with specific embodiments.

[0050] refer to Figure 1 As shown, an embodiment of the present application proposes an infusion system, which may include an infusion device 200 and a data acquisition device 100, wherein the infusion device 200 may be an infusion device such as a nutrition pump, and includes a controller, a driving mechanism, an extrusion component, and an infusion line 210. The driving mechanism is transmission-connected to the extrusion component, and the infusion line 210 is a pipeline for conveying fluid (such as liquid medicine or nutrient solution), one end of which is connected to a fluid storage device, and the other end is used to connect to a patient. The extrusion component (such as a pump wheel) is located on the infusion line 210. During the operation of the infusion device, the controller controls the operation of the driving mechanism, thereby driving the extrusion component to extrude the infusion line 210, and then driving the fluid in the infusion line 210 to flow.

[0051] The data acquisition device 100 is provided on the infusion device 200 and is located on the infusion line 210. The data acquisition device 100 can collect the state of the fluid flow in the infusion line 210 of the infusion device and form data. When the infusion device is in a continuous operation state, the data acquisition device 100 can collect the state of the fluid flow in the infusion line 210 of the infusion device at different times and form a plurality of data.

[0052] In the detection device of the infusion system of the present application, the infusion line 210 state detection function can be realized by only setting up one data acquisition device 100 and using the data acquisition device 100 to collect data on the fluid flow state in the infusion line 210 multiple times, thereby reducing the number of data acquisition devices 100 and reducing the types of data collected by the data acquisition device 100, thereby achieving the purpose of simplifying the infusion system structure.

[0053] In some embodiments, reference Figure 2As shown, the data acquisition device 100 of the present application may specifically adopt a bubble sensor. The infusion pipeline 210 includes an upstream pipeline and a downstream pipeline that are connected, an extrusion component (such as a pump wheel) is located between the upstream pipeline and the downstream pipeline, and the bubble sensor is located at the upstream pipeline. The bubble sensor may include a transmitter 110 and a receiver 120, the transmitter 110 and the receiver 120 are correspondingly arranged, and the transmitter 110 and the receiver 120 may be arranged on the infusion pipeline 210. The transmitter 110 may transmit an ultrasonic signal to the infusion pipeline 210, and the ultrasonic signal may reach the receiver 120 after passing through the infusion pipeline 210. The transmitter 110 and the receiver 120 may be arranged relatively, and the infusion pipeline 210 may be located between the transmitter 110 and the receiver 120. The ultrasonic signal emitted by the transmitter 110 may reach the receiver 120 after passing through the infusion pipeline 210 and be received by the receiver 120. Ultrasonic signals have poor transmission effects in the air and are easily attenuated, while ultrasonic signals have good transmission effects in fluids and are less attenuated. When the transmitter 110 transmits ultrasonic waves to the infusion line 210, if the infusion line 210 is filled with liquid, the ultrasonic signal will not have obvious signal attenuation after passing through the infusion line 210, and the signal value of the ultrasonic signal received by the receiver 120 is relatively high.

[0054] When bubbles appear in the infusion line 210, the bubbles contain air, and the ultrasonic signal will be significantly attenuated when passing through the bubbles in the infusion line 210, so that the signal value of the ultrasonic signal received by the receiving unit 120 is reduced. Similarly, when the infusion line 210 is blocked from above and the line 210 is contracted, the ultrasonic signal will be attenuated relatively more, so that the signal value of the ultrasonic signal received by the receiving unit 120 is reduced.

[0055] Therefore, when the infusion line 210 is in a normal state, a blocked state, or a bubble state, the data collected by the data acquisition device 100 are different. The infusion line 210 has different data characteristics when it is in a normal state, a blocked state, or a bubble state. Therefore, according to the data collected by the data acquisition device 100, it can be determined that the infusion line 210 is in a normal state, a blocked state, or a bubble state. It should be noted that when the data acquisition device 100 is located at the upstream pipeline, the blocked state is the upper blocked state; when the data acquisition device 100 is located at the downstream pipeline, the blocked state is the lower blocked state.

[0056] In addition, the transmitting unit 110 and the receiving unit 120 may also be disposed on the same side of the infusion line 210 , and the ultrasonic signal emitted by the transmitting unit 110 may be reflected to the receiving unit 120 after reaching the infusion line 210 .

[0057] The embodiment of the present application also proposes an infusion line detection method, which can be applied to the infusion system described above. The infusion system includes an infusion device 200, and a data acquisition device 100 that is communicatively connected to the infusion device 200, and the data acquisition device 100 is located on the infusion line 210 of the infusion device 200. Figure 3 As shown, the method includes:

[0058] S100, obtaining data collected by the data acquisition device at at least two moments when the infusion device is in operation. The infusion device is in operation when the infusion device is performing an infusion action, and at this time, there is fluid in the infusion line 210 of the infusion device, and the infusion device drives the fluid in the infusion line 210 to flow along the infusion line 210. The data acquisition device 100 can collect data at at least two moments, and the data is related to the flow of the fluid in the infusion line 210, and specifically, the data is an ultrasonic signal value.

[0059] S200, determining the infusion state of the infusion line according to the data collected by the data collection device at at least two moments, where the infusion state includes a normal state, a blocked state or a bubble state.

[0060] The data collected by the data acquisition device at different times can reflect the flow conditions of the fluid in the infusion pipeline at different times. By comparing and analyzing the data collected by the data acquisition device at different times, the changes in the fluid in the infusion pipeline can be obtained, so that it can be known whether the infusion state of the infusion pipeline is in a normal state, a blocked state or a bubble state.

[0061] In some embodiments, reference Figure 4 As shown, step S200 specifically includes:

[0062] If the data collected by the data acquisition device at the first moment is less than or equal to the first data threshold, the infusion state of the infusion circuit is determined according to the change of the data collected by the data acquisition device after the first moment.

[0063] Specifically, the data collected by the data acquisition device 100 is compared with the first data threshold. When the data collected by the data acquisition device 100 is greater than the first data threshold, it means that compared with the ultrasonic signal under normal conditions, the current ultrasonic signal has almost no attenuation, and the infusion state of the infusion line 210 is normal. When the data collected by the data acquisition device 100 is less than or equal to the first data threshold, it means that compared with the ultrasonic signal under normal conditions, the attenuation of the current ultrasonic signal is large, and the flow condition of the fluid in the infusion line 210 is abnormal, and there may be blockage or bubbles. Therefore, according to the changes in the data collected by the data acquisition device 100 after the first moment, it can be determined that the infusion state of the infusion line 210 is a blocked state or a bubble state.

[0064] In some embodiments, determining the infusion state of the infusion circuit according to the change of the data collected by the data collection device after the first moment may further include:

[0065] The infusion state of the infusion circuit is determined according to the change rate of the data collected by the data collection device after the first moment.

[0066] Among them, the rate of change of data represents the change value of the data in a unit time. Specifically, no matter whether the infusion line 210 is in a blocked state or a bubble state, the data collected by the data acquisition device 100 will be attenuated to a certain extent. However, when the infusion line 210 is in a blocked state and a bubble state, the attenuation of the ultrasonic signal is different. When the infusion line 210 is in a blocked state, the ultrasonic signal is in a slowly decreasing state, and its attenuation rate is slower; when the infusion line 210 is in a bubble state, the ultrasonic signal is in a rapidly decreasing state, and its attenuation rate is faster. That is, the rate of change of the data when the infusion line 210 is in a blocked state is less than the rate of change of the data when the infusion line 210 is in a bubble state.

[0067] The controller of the infusion device stores a change rate threshold value related to the change rate of the ultrasonic signal. If the change rate of the data collected by the data acquisition device 100 after the first moment is less than the change rate threshold value, it means that the ultrasonic signal is in a slowly decreasing state, and at this time, the infusion state of the infusion line 210 is a blocked state. If the change rate of the data collected by the data acquisition device 100 after the first moment is greater than the change rate threshold value, it means that the ultrasonic signal is in a rapidly decreasing state, and at this time, the infusion state of the infusion line 210 is a bubble state. Therefore, according to the relationship between the change rate of the data collected by the data acquisition device 100 after the first moment and the change rate threshold value, it can be determined that the infusion state of the current infusion line is a blocked state or a bubble state.

[0068] In some embodiments, determining the infusion state of the infusion circuit according to the change of the data collected by the data collection device after the first moment may further include:

[0069] Acquire the quantity and / or duration of data between a first data threshold and a second data threshold collected by a data collection device after a first moment;

[0070] The infusion state of the infusion line is determined according to the amount and / or duration of the data between the first data threshold and the second data threshold.

[0071] Specifically, during the operation of the infusion device, the data acquisition device 100 can collect data in real time and continuously at a certain frequency, and the data collected by the data acquisition device 100 can be compared with the first data threshold and the second data threshold to determine the infusion state of the infusion line 210. The first data threshold is greater than the second data threshold.

[0072] When the flow condition of the fluid in the infusion line 210 is normal, the data collected by the data acquisition device 100 will be greater than the first data threshold. If the data collected by the data acquisition device 100 before a certain moment are all greater than the first data threshold, but the data collected at and after a certain moment are between the first data threshold and the second data threshold, this moment is defined as the first moment, and the number of times the data acquisition device 100 collects data is recorded from the first moment.

[0073] After the first moment, if the data collected by the data acquisition device 100 before another moment are all between the first data threshold and the second data threshold, but the data collected at and after another moment are less than or equal to the second data threshold, the other moment is defined as the second moment. At the second moment, the data acquisition device 100 may stop recording the number of times the data acquisition device 100 collects data. In this way, the total number of times the data acquisition device 100 collects data during the time period from the first moment to the second moment is the number of data collected by the data acquisition device 100 between the first data threshold and the second data threshold. Whether the infusion line 210 is in a blocked state or has bubbles can be determined based on the number of data collected by the data acquisition device 100 between the first data threshold and the second data threshold.

[0074] Specifically, no matter the infusion line 210 is in a blocked state or a bubble state, the data collected by the data acquisition device 100 will decrease. If the infusion line 210 is blocked, so that the liquid cannot be smoothly input into the infusion line 210, then the amount of liquid in the infusion line 210 will gradually decrease, which will cause the data collected by the data acquisition device 100 to slowly decrease. In this way, when the infusion line 210 is in a blocked state, the amount of data collected by the data acquisition device 100 between the first data threshold and the second data threshold is relatively large.

[0075] If bubbles appear in the infusion line 210, the ultrasonic signal will be severely attenuated when passing through the bubbles, so that the data collected by the data acquisition device 100 will quickly drop to the second data threshold. In this way, when the infusion line 210 is in a bubble state, the amount of data collected by the data acquisition device 100 between the first data threshold and the second data threshold is small.

[0076] As can be seen from the above, the number of data between the first data threshold and the second data threshold collected by the data acquisition device 100 is compared with the first preset value. If the number of data between the first data threshold and the second data threshold collected by the data acquisition device 100 is greater than the first preset value, it means that the infusion line 210 is in a blocked state. If the number of data collected by the data acquisition device 100 between the first moment and the second moment is less than or equal to the first preset value, it means that the infusion line 210 is in a bubble state. Therefore, it can be judged whether the infusion line 210 is in a blocked state or a bubble state according to the number of data between the first data threshold and the second data threshold collected by the data acquisition device 100.

[0077] In addition, the duration from the first moment to the second moment can also be calculated, that is, the duration of the data collected by the data acquisition device between the first data threshold and the second data threshold. If the duration is greater than the preset duration, it means that the infusion line 210 is in a blocked state, and if the duration is less than the preset duration, it means that the infusion line 210 is in a bubble state. It can be understood that the duration from the first moment to the second moment can be directly calculated, and the duration from the first moment to the second moment can also be determined by the relationship between the number of data collected by the data acquisition device 100 between the first data threshold and the second data threshold and the frequency of data collection by the data acquisition device 100.

[0078] In some embodiments, determining the infusion state of the infusion circuit according to the change of the data collected by the data collection device after the first moment may further include:

[0079] Determine the infusion state of the infusion circuit according to the difference between the data collected by the data collection device after the first moment and the first data threshold. Specifically, it may include:

[0080] Calculate the difference between the data collected by the data collection device after the first moment and the first data threshold;

[0081] Determine whether the difference is greater than or equal to a first difference threshold, and if so, determine that the infusion line is in a bubble state;

[0082] If not, determine whether the difference is greater than or equal to a second difference threshold, and if so, determine that the infusion line is in a blocked state, wherein the second difference threshold is less than the first difference threshold.

[0083] Specifically, the data acquisition device 100 can continuously collect data after the first moment. If the difference between the data collected by the data acquisition device after the first moment and the first data threshold is greater than or equal to the first difference threshold, it means that among the data collected by the data acquisition device 100 after the first moment, there is data with a large difference from the first data threshold, which further indicates that the data collected by the data acquisition device 100 has a large attenuation. When bubbles appear in the infusion line 210, the data collected by the data acquisition device 100 also decreases significantly in a short period of time. In this way, when the difference is greater than or equal to the first difference threshold, it can be indicated that bubbles appear in the infusion line 210, and it can be determined that the infusion line 210 is in a bubble state.

[0084] If the difference between the data collected by the data acquisition device after the first moment and the first data threshold is greater than or equal to the second difference threshold, and less than the first difference threshold, it means that the difference between the data collected by the data acquisition device 100 after the first moment and the first data threshold is relatively small, and further indicates that the change amplitude of the data collected by the data acquisition device 100 after the first moment is relatively small. When a blockage occurs in the infusion line 210, the data collected by the data acquisition device 100 decreases relatively smoothly over a period of time. In this way, when the difference is less than the first difference threshold and greater than the second difference threshold, it can be indicated that a blockage occurs in the infusion line 210, and the infusion line 210 can be determined to be in a blocked state.

[0085] It should be noted that, as long as there is data whose difference with the first data threshold value is greater than or equal to the first difference threshold value in the data collected by the data acquisition device 100 after the first moment, it can be determined that the infusion line 210 is in a state of bubbles. For example, after the first moment, the difference between the data collected by the data acquisition device 100 at the second moment and the first data threshold value is greater than the first difference threshold value. If the data collected by the data acquisition device 100 after the second moment increases again, even if the difference between the data collected by the data acquisition device 100 after the second moment and the first data threshold value is less than the first difference threshold value, the infusion line 210 is still considered to be in a state of bubbles. In other words, as long as the signal value collected by the data acquisition device 100 after the first moment attenuates significantly, no matter how the subsequent data changes, it is considered that the infusion line 210 is in a state of bubbles at the second moment, and a corresponding alarm prompt is issued to avoid the situation of missing reports of bubbles.

[0086] Similarly, after the first moment, the difference between the data collected by the data acquisition device 100 at the third moment and the first data threshold is between the first difference threshold and the second difference threshold. If the data collected by the data acquisition device 100 after the third moment increases again, even if the data collected by the data acquisition device 100 after the third moment is greater than the first data threshold, the infusion line 210 is still considered to be in a blocked state, and a corresponding alarm prompt is issued to avoid missed reporting of blockage.

[0087] Furthermore, when the flow condition of the fluid in the infusion line 210 is normal, the data collected by the data acquisition device 100 will be continuously and stably greater than the first data threshold. If the data collected by the data acquisition device 100 is greater than the first data threshold within a time period, but the data collected at the first moment is suddenly less than or equal to the first data threshold, the infusion state of the infusion line 210 can be determined based on the change of the data collected by the data acquisition device 100 after the first moment. If the data collected by the data acquisition device 100 at a certain moment after the first moment is continuously and stably greater than the first data threshold, it is considered that the infusion line 210 has returned to a normal state, and the infusion state of the infusion line 210 is continued to be determined based on the data collected by the data acquisition device 100 at at least two moments after the moment.

[0088] In some embodiments, the infusion line detection method of the present application further includes the following steps:

[0089] Output alarm information or prompt information corresponding to the infusion status.

[0090] The infusion system may also include an alarm device 500 electrically connected to the data acquisition device 100. When the infusion line 210 is in a blocked state or a bubble state, it indicates that there is a problem with the flow of liquid in the infusion line 210, and further indicates that there is a problem with the infusion device. At this time, an alarm prompt is issued through the alarm device 500 to prompt the user to take corresponding measures. Specifically, the alarm device 500 may include a buzzer, an indicator light, and a display module. When the infusion line 210 is in a blocked state or a bubble state, the buzzer may emit an alarm sound corresponding to the blocked state and an alarm sound corresponding to the bubble state. The display module may display text information to indicate that the infusion line 210 of the infusion device is in a blocked state or a bubble state. In addition, the display module may also display text information to indicate that the infusion line 210 is in a normal state.

[0091] In some embodiments, different infusion states have different alarm information or prompt information. For example, normal state, blocked state, and bubble state correspond to indicator lights of different colors, respectively. By displaying indicator lights of different colors, the current infusion state can be intuitively distinguished.
