Figure 2a is a schematic structural diagram of a drug infusion device provided in Embodiment 1 of the present application. The drug infusion device includes: a housing 210, a motor 220, and an infusion line 230, which are sequentially arranged on the path of the infusion line with the motor 220 connects the first pump piece 240 , the extruding pump piece set 250 and the second pump piece 260 , the detection component 270 arranged on the infusion line path, and the data processor 280 connected with the detection component 270 . The detection component 270 detects the state parameter of the infusion line 230, and sends the detected state parameter to the data processor 280; the data processor 280 detects the first state parameter according to the first infusion stage detection component 270, and/or Or, the second status parameter detected by the second infusion phase detection component 270 determines whether the infusion line of the drug infusion set is blocked. It should be noted that the structure of the drug infusion device in FIG. 2a is only an example, and in particular, the setting position of the detection component 270 is not limited. Further, the data processor 280 outputs blockage detection information, and the blockage detection information output by the data processor 280 at least prompts that the pipeline is blocked. Of course, the output blocking information can further prompt that the pipeline is not blocked, so that the user can read it. In some embodiments, the data processor 280 may output flags used to characterize "obstruction" and "non-obstruction", such as 1 and 0, wherein 1 represents the infusion line is blocked, and 0 represents that the infusion line is not blocked. . Of course, in addition to the logo, the output blocking detection information may also be in the form of one or more combinations of text, graphics, symbols, colors, voices, and the like.

The first pump piece 240 , the extrusion pump piece set 250 and the second pump piece 260 , and the local infusion line 230 are disposed inside the casing 210 . Wherein, the first pump piece 240 , the extruding pump piece set 250 and the second pump piece 260 are respectively connected to the motor 220 .

One end of the motor 220 is connected to an infusion pipeline 230, which is a pipeline for delivering medicine, and the infusion pipeline 230 is connected to an external required storage component, and the other end of the motor 220 is connected to another infusion pipeline , the other infusion line is connected to the body of the infusion subject to pump the external drug into the infusion subject, where the infusion subject may include but not limited to human body, animal body, etc. The first pump patch 240 controls the flow of drug into the drug infusion set. The extruded pump tablet set 250 may be a pump tablet group or a pump tablet group composed of a plurality of extruded pump tablets, which can be used to deliver medicine by extrusion. The second pump patch 260 controls the flow of drug out of the drug infusion set. The structure of the first pump piece 240 , the second pump piece 260 , and each extrusion pump piece in the squeeze pump piece group is not limited here, and the structures of the above pump pieces may be the same or different.

The state parameter of the infusion line 230 may be a state parameter used to characterize the flow of the drug in the infusion line, and to determine whether the infusion line is blocked. The detection component 270 detects the state of the infusion pipeline 230, including the first infusion phase, the second infusion phase, and the infusion pipeline under the first infusion phase and the second infusion phase in the same cycle. Check the status parameters. Correspondingly, the state parameter detected in the first infusion stage is the first state parameter, and the state parameter in the second infusion stage is the second state parameter.

The state parameters detected in different infusion stages are used to characterize the liquid flow state in different pipeline regions of the infusion pipeline 230, wherein the different pipeline regions of the infusion pipeline 230 may include the upper pipeline region and the lower pipeline region relative to the detection component 270, Here the upper pipe area and the lower pipe area are determined based on the flow direction of the liquid. By detecting the state parameters of different infusion stages, the blockage detection of different pipeline regions of the infusion pipeline 230 is realized. Wherein, the first infusion phase may be an infusion intermittent phase of an infusion cycle, and the second numerical phase is an infusion phase of an infusion cycle.

On the basis of the above embodiments, the detection component 270 can be installed at different positions on the infusion line path. For example, refer to Fig. 2a-Fig. 2e, Fig. 2a-Fig. 2e are the structural schematic diagrams of the drug infusion state provided by the embodiment of the present application respectively, wherein the detection components 270 are respectively arranged at different positions on the infusion pipeline. In some embodiments, the detection component 270 can be arranged on the infusion line path between the first pump piece 240 and the extrusion pump piece set 250, see FIG. 2b. In some embodiments, the detection component 270 is arranged on the infusion line path between the extruded pump piece set 250 and the second pump piece 260 , for example, see FIG. 2 a . In some embodiments, the detection component 270 is arranged on the extruding pump sheet set 250, for example, refer to Fig. 2c. In some embodiments, the detection component 270 is disposed on the first pump piece 240, for example, refer to Fig. 2d. In some embodiments, the detection component 270 is disposed on the second pump piece, for example, refer to Fig. 2e.

Based on the drug infusion device with any structure above, the detection component 270 can detect the first state parameter in the first infusion state and/or the second state parameter in the second infusion state. The detection component sends the monitored state parameters to the data processor 280 .

The data processor 280 receives the state parameters sent by the detection component 270, analyzes and processes the state parameters, and determines the blockage of the infusion line. Specifically, whether the upper end of the infusion line of the drug infusion set is blocked can be determined based on the first state parameter in the first infusion stage based on one or more cycles; or, it can be determined based on one or more cycles in the second The second state parameter of the infusion phase determines whether the lower end of the drug infusion set is blocked, or may be based on one or more cycles of the first state parameter during the first infusion phase and the second state parameter during the second infusion phase. The state parameters collectively determine whether the upper and lower ends of the drug infusion set are obstructed.

In the technical solution of this embodiment, by providing a drug infusion device, the detection device installed on the infusion line path detects the state parameters of the infusion line, and sends the detected state parameters of the infusion line to The data processor performs processing and finally determines that the infusion line is blocked. The purpose of diversification of detection methods, cost reduction and structure simplification is realized. When the infusion line blockage in the drug infusion device is detected, blockage prompt information can be generated to prompt the operator to check the drug infusion device to ensure normal drug infusion.

In the above embodiment, different types of detection components can be used to detect the state parameters of the infusion pipeline 230, and correspondingly, different types of state parameters can be obtained through detection. A corresponding type of first state parameter is detected during the infusion phase, and/or a corresponding type of second state parameter is detected during the second infusion phase. In this embodiment, one or more types of state parameters can be used to determine whether the infusion line of the drug infusion device is blocked. Here, different types of state parameters can correspond to different judgment rules. Correspondingly, data processing The determination rule corresponding to the detection component type is stored in the device 280, so as to realize the determination of whether the infusion line is blocked.

Optionally, the detection component 270 may be one or more of a pressure detection component, a distance detection component, a deformation detection component, and a liquid flow detection component. In some embodiments, two or more detection components are set in the drug infusion state, and it is possible to determine whether the infusion line is blocked through various types of state parameters. The judgment results of each other are checked against each other to improve the correctness of the judgment results.

Wherein, the pressure detection component is configured to detect the pressure on the infusion pipeline, and the pressure detection component may be a device for detecting pressure such as a pressure sensor. When the medicine flows through the infusion pipeline, the medicine generates pressure on the infusion pipeline 230 , and correspondingly, when there is an obstruction on the infusion pipeline 230 , the pressure generated on the infusion pipeline 230 is also different. For example, in the first infusion phase, when there is an obstruction in the upper pipeline area, the medicine cannot flow into the infusion pipeline 230, resulting in a small pressure on the infusion pipeline 230; in the second infusion phase, the lower pipeline area In the case of blockage, the drug cannot flow out of the infusion line 230, and the pressure on the infusion line 230 is high.

The pressure detection component detects the pressure of the medicine on the infusion line 230, correspondingly, the first state parameter is the first pressure value, and the second state parameter is the second pressure value.

The distance detection component is configured to detect the displacement of the medicine inside the infusion line, and the distance detection component can be a distance sensor, an ultrasonic sensor and other devices for detecting distance. During the process of the medicine flowing through the infusion pipeline 230, the displacement of the medicine inside the infusion pipeline 230 is detected. The displacement here may be the displacement along the vertical direction of the liquid flow direction. In the event of an obstruction, the displacement of the drug in the infusion line 230 is also different. For example, in the first infusion stage, when there is an obstruction in the upper pipeline area, the medicine cannot flow into the infusion pipeline 230, and there is less medicine in the infusion pipeline 230, resulting in a decrease in the displacement of the medicine in the infusion pipeline 230; In the second infusion stage, when the lower end pipeline area is blocked, the medicine cannot flow out of the infusion pipeline 230 , and there is too much medicine in the infusion pipeline 230 , resulting in a large displacement of the medicine in the infusion pipeline 230 .

When the distance detection component is installed on the infusion pipeline, the displacement of the drug inside the infusion pipeline is measured on the surface of the infusion pipeline, correspondingly, the first state parameter is the first displacement value, and the second state parameter is the second displacement value.

The deformation detection component is configured to detect whether the infusion pipeline is deformed, and the deformation detection component may be a deformation sensor or other device for detecting deformation. When the drug flows through the infusion line 230, the state of the infusion line 230 is changed by the drug. Correspondingly, when there is a blockage on the infusion line 230, the deformation of the infusion line 230 caused by the drug Also different. The deformation here includes concave and convex of the infusion line 230 . For example, in the first infusion stage, when there is an obstruction in the upper pipeline area, the medicine cannot flow into the infusion pipeline 230, and there is less medicine in the infusion pipeline 230, resulting in concave deformation of the infusion pipeline 230; In the infusion phase, when the lower end of the pipeline area is blocked, the medicine cannot flow out of the infusion pipeline 230 , and the infusion pipeline 230 contains a lot of medicine, resulting in convex deformation of the infusion pipeline 230 . The deformation detection component detects the first deformation value and the second deformation value respectively at different infusion stages. It should be noted that the deformation value can be positive or negative. For example, a positive deformation represents a convex deformation value, and a negative deformation represents a concave deformation value. .

The liquid flow detection component is configured to detect the liquid flow state of the infusion pipeline, and the liquid flow detection component may be a device for detecting the liquid flow state such as a liquid flow sensor. When the drug flows through the infusion line 230, the liquid flow state of the infusion line 230 is detected by the liquid flow detection component, wherein the liquid flow state may include whether the liquid is flowing, or the liquid flow state may include the flow velocity. When the state of the infusion line changes, the liquid flow state of the infusion line also changes accordingly. For example, if there is a blockage in the infusion line 230, the liquid does not flow, or the flow rate of the liquid is small. In the case of , the liquid flow velocity is high.

Correspondingly, the first state parameter may be the first flow velocity, and the second state parameter may be the second flow velocity.

On the basis of the above embodiments, the data processor 280 is configured to determine that the infusion line is blocked according to one or more detected first state parameters and/or second state parameters. The first state parameter and the second state parameter here may be state parameters detected based on any one of the detection components 270 described above. Exemplarily, taking the detection component 270 as a pressure detection component as an example, the values of the first state parameter and the second state parameter are the pressure values detected by the pressure detection component; for example, taking the detection component 270 as the distance detection component is For example, the values of the first state parameter and the second state parameter are the distance values detected by the distance detection component; for example, taking the detection component 270 as the deformation detection component as an example, the values of the first state parameter and the second state parameter is the direction of deformation and the specific deformation amount detected by the deformation detection component; for example, taking the detection component 270 as a liquid flow detection component as an example, the values of the first state parameter and the second state parameter are detected by the liquid flow detection component The resulting flow velocity value.

The detection component 270 can detect the state parameters of the infusion pipeline 230 in real time, and send the detected state parameters to the data processor 280, or, when receiving the detection instruction, detect the current cycle or the next period when the detection instruction is received. A state parameter of the infusion line 230 during the cycle. The data processor 280 can determine whether the infusion line is blocked according to the detection state parameters of one cycle or multiple cycles, for example, process the state parameters obtained in multiple detection cycles to determine whether the infusion line is blocked, and can also process each The state parameters obtained in one cycle to determine whether the infusion line is blocked; it can also be the number of cycles of the pre-set processing detection cycle, and the state parameters obtained in the cycle corresponding to the set number of cycles to determine whether the infusion line is blocked block.

In some embodiments, the data processor 280 determines that the infusion line is blocked according to the detected first state parameter and/or the second state parameter and a corresponding preset threshold. For example, determining the blockage of the infusion line based on the first state parameter and the first threshold; or, determining the blockage of the infusion line based on the second state parameter and the second threshold; or, determining the blockage of the infusion line based on the first state parameter, the second state parameter and the second Three thresholds determine infusion line obstruction.

Determining blockage of the infusion line based on the first state parameter and the first threshold value, including comparing the first state parameter with the first threshold value, and determining the status of the drug infusion device when the first state parameter satisfies the first threshold value comparison condition The upper pipeline region is not blocked, and if the first state parameter does not meet the comparison condition of the first threshold, it is determined that the upper pipeline region of the drug infusion device is blocked. Wherein, different types of state parameters correspond to different first thresholds, and/or, the corresponding first threshold comparison conditions are different. Taking the state parameter as the pressure value as an example, if the first pressure value is greater than the first pressure threshold, it is determined that the first threshold comparison condition is met, that is, the upper pipeline area of the drug infusion device is not blocked, and the first pressure value If it is less than the first pressure threshold, it is determined that the first threshold comparison condition is not met, that is, the upper pipeline region of the drug infusion device is blocked. Taking the state parameter as the displacement value as an example, if the first displacement value is greater than the first displacement threshold, it is determined that the first threshold value comparison condition is met, that is, the upper pipeline area of the drug infusion device is not blocked, and at the first displacement value If it is smaller than the first displacement threshold, it is determined that the first threshold comparison condition is not met, that is, the upper pipeline region of the drug infusion device is blocked. Taking the state parameter as the liquid flow state as an example, when the first flow velocity is greater than the first flow velocity threshold, it is determined that the first threshold comparison condition is met, that is, the upper pipeline area of the drug infusion device is not blocked, and at the first If the flow velocity value is less than the first flow velocity threshold, it is determined that the first threshold comparison condition is not satisfied, that is, the upper pipeline region of the drug infusion set is blocked. Taking the state parameter as an example, when the first deformation value is positive and the first deformation value is greater than the first deformation threshold, it is determined that the first threshold comparison condition is satisfied, that is, the upper pipeline area of the drug infusion set No blockage, if the first deformation value is less than the first deformation threshold, it is determined that the first threshold comparison condition is not met, that is, the upper pipeline region of the drug infusion set is blocked.

Determining blockage of the infusion line based on the second state parameter and the second threshold value, including comparing the second state parameter with the second threshold value, and determining the status of the drug infusion device when the second state parameter satisfies the second threshold value comparison condition The lower pipeline area is not blocked, and if the second state parameter does not meet the comparison condition of the second threshold, it is determined that the lower pipeline area of the drug infusion device is blocked. Wherein, different types of state parameters correspond to different second thresholds, and/or, the corresponding second threshold comparison conditions are different. Taking the state parameter as the pressure value as an example, if the second pressure value is greater than the second pressure threshold, it is determined that the second threshold comparison condition is not satisfied, that is, the lower end pipeline area of the drug infusion device is blocked, and at the second pressure value If it is less than the second pressure threshold, it is determined that the second threshold comparison condition is met, that is, the lower pipeline area of the drug infusion device is not blocked. Taking the state parameter as the displacement value as an example, if the second displacement value is greater than the second displacement threshold, it is determined that the second threshold comparison condition is not satisfied, that is, the lower end pipeline area of the drug infusion device is blocked, and the second displacement value If it is smaller than the second displacement threshold, it is determined that the second threshold comparison condition is met, that is, the lower end pipeline region of the drug infusion device is not blocked. Taking the state parameter as the liquid flow state as an example, when the second flow velocity is greater than the second flow velocity threshold, it is determined that the second threshold comparison condition is met, that is, the lower end pipeline area of the drug infusion device is not blocked, and the second flow velocity threshold is met. If the flow velocity value is less than the second flow velocity threshold, it is determined that the second threshold comparison condition is not satisfied, that is, the lower end pipeline area of the drug infusion set is blocked. Taking the state parameter as an example, when the second deformation value is positive deformation and the second deformation value is greater than the second deformation threshold, it is determined that the second threshold comparison condition is not met, that is, the lower end pipeline of the drug infusion device Area blockage, when the second deformation value is negative deformation and less than the second deformation threshold, it is determined that the second threshold comparison condition is met, that is, the lower tube area of the drug infusion device is not blocked.

Determine the blockage of the infusion line based on the first state parameter, the second state parameter and the third threshold, including: comparing the sum of the first state parameter and the second state parameter with the third threshold, and determining the infusion according to the comparison result Whether the pipeline is blocked. Taking the state parameter as the pressure value as an example, if the pressure sum of the first pressure value and the second pressure value is greater than the third pressure threshold, it is determined that the lower end of the infusion line is blocked. If the pressure sum of the two pressure values is less than the third pressure threshold, it is determined that the upper end of the infusion line is blocked. Taking the state parameter as the deformation value as an example, when the deformation sum of the first deformation value and the second deformation value is greater than the third deformation threshold, it is determined that the lower end of the infusion line is blocked. If the deformation sum of the two deformation values is less than the third deformation threshold, it is determined that the upper end of the infusion line is blocked. Taking the state parameter as the displacement value as an example, when the displacement sum of the first displacement value and the second displacement value is greater than the third displacement threshold, it is determined that the pipeline area at the lower end of the infusion line is blocked. If the displacement sum of the two displacement values is less than the third displacement threshold, it is determined that the upper end of the infusion pipeline is blocked. Taking the state parameter as the liquid flow state as an example, when the sum of the first flow velocity and the second flow velocity is greater than the third velocity threshold, it is determined that there is no blockage on the infusion line. When the sum of the speeds is less than the third speed threshold, it is determined that there is an obstruction on the infusion line.

In some embodiments, the data processor 280 may determine that the infusion line is blocked according to multiple detected changes of the first state parameter and/or changes of the second state parameter. Specifically, the data processor 280 may determine a parameter change according to the first state parameter and/or the second state parameter detected multiple times, and determine that the infusion line of the drug infusion device 230 is blocked based on the parameter change.

The data processor 280 may determine that the infusion line 230 is blocked based on changes in the detected state parameters over a plurality of cycles. For example, the difference between the current state parameter and the corresponding state parameters of other cycles can be expressed as the change of the state parameter. Correspondingly, the change of the state parameter can include the state parameter in the current cycle and the state parameters in multiple other cycles Respective differences, where the number of other periods is at least one. The change of the state parameter can also be represented by the change of two adjacent difference values, or it can also be represented by the slope of the change of the state parameter. Specifically, the judgment may be made by comparing the change of the state parameter with a preset threshold. The change of the state parameter includes at least one of the change of the first state parameter, the change of the second state parameter, the parameter and the change of the first state parameter and the second state parameter. The above-mentioned first state parameter and second state parameter may be any parameter type among pressure value, deformation value, displacement value and liquid flow state.

If the change of the first state parameter does not meet the parameter change condition, it is determined that the upper end of the infusion line is blocked. Specifically, in a case where the differences in the changes of the first state parameter are greater than the first difference threshold, it is determined that the upper end pipeline area of the infusion management is blocked. In the case that the change of the second state parameter does not meet the parameter change condition, it is determined that the upper pipeline region of the infusion management is blocked, specifically, each difference in the change of the second state parameter is greater than the second difference threshold In this case, it was determined that the lower line area of the infusion management is blocked. In the case of the parameters and changes of the first state parameter and the second state parameter, each parameter and the difference are greater than the third difference threshold, it is determined that the lower end pipeline area of the infusion management is blocked, and when each parameter and the difference are equal If it is less than the fourth difference threshold, it is determined that the upper line region of the infusion management is blocked.

In this embodiment, the data processor 280 is further configured to perform verification based on multiple detected blockages, and determine that the infusion line of the drug infusion set is blocked if the continuous verification condition is met. The number of verification times can be preset, for example, it can be set to 3 times, and the continuous verification condition can be preset as the continuous verification times. When the infusion line blockage is detected, when the continuous verification condition is met, the infusion line blockage is determined. When the continuous verification conditions are met, it is determined that the infusion line is not blocked. The blockage of the infusion line can be due to external factors such as manual pressing and misoperation. After eliminating external interference, confirm again.

The technical solution provided by the embodiment of the present application avoids occasional false detection by performing continuous verification on the verification results, thereby improving the accuracy of judging the blockage of the infusion line.

On the basis of the foregoing embodiments, Embodiment 1 of the present application also provides an example of a drug infusion device, where a portable infusion pump is selected as the drug infusion device. Including housing, motor, valve-out pump piece (that is, the second pump piece), extrusion pump piece, pressure sensor, and valve-in pump piece (that is, the first pump piece), the drug infusion device may include a data processor (Fig. 3 not shown, connected to the pressure sensor). As shown in Figure 3.

The portable infusion pump includes 3 pump slices, and the 3 pump slices are separated by a certain distance, and its pressure sensor can be located in the interval between any two pump slices.

Because the portable infusion pump is in intermittent infusion mode, during the intermission of infusion, the pressure sensor can detect the upper occlusion pressure, which is the first state parameter; during the infusion process, the pressure sensor can detect the lower occlusion pressure, which is the second state parameter.

The data processor judges the blockage based on the upper and/or lower blockage pressure collected by the pressure sensor. The method 1 for determining the upper and lower blockage pressure is: the pressure sensor is equipped with an analog-to-digital converter, and the collected analog pressure value is converted into The digital pressure value, that is, the AD value, compares the real-time read AD value with the upper occlusion pressure AD threshold set in the register when measuring the upper occlusion pressure, and it is judged as upper occlusion if it is lower than the AD threshold; When comparing the AD value read in real time with the AD value of the lower blocking pressure set in the register, it is judged as lower blocking if it is higher than the AD threshold.

The judgment method 2 of the upper and lower occlusion pressure is: the pressure sensor converts the pressure value into an AD value, and stores the real-time read AD value in the register when measuring the upper occlusion pressure, and compares the value with the AD value read within the set number of times. When the difference is greater than a set value, it is judged to be an upper blockage, and the AD value before the set number of times can be deleted in the register; when the lower blockage pressure is measured, the AD value read in real time is stored in the register , compare this value with the AD value read within the set number of times, and when the difference is greater than a set value, it is judged to be down blocking, and the AD value before the set number of times can be deleted in the register.
