[0030] Embodiment One

[0031] Figure 1 is a working principle diagram of an infusion process of a drug infusion device provided by an embodiment of the present application. The drug infusion device delivers drugs to an infusion object through an infusion pipeline, wherein the infusion process of the drugs includes two infusion stages, and the flow direction of the drugs is as shown in Figure 1As shown, it is to be noted that the drug in the embodiment is a liquid drug. In the first infusion stage, the first pump piece 240 is opened, while the second pump piece 260 is closed, and the drug flows into the drug infusion device. In the second infusion stage, the first pump piece 240 is closed, while the second pump piece 260 is opened, and the pump piece group 250 is squeezed to pressurize the infusion pipeline, the pump piece group 250 at least includes one squeezing pump piece, the pump piece group squeezes the drug in the infusion pipeline, the drug flows out of the drug infusion device through the second pump piece, and the drug is infused into the infusion object by the motor. When the first pump piece 240 is closed, the liquid cannot flow into the drug infusion device through the infusion pipeline, and when the second pump piece 260 is closed, the liquid cannot flow out of the drug infusion device into the infusion object.

[0032] Figure 2a is a structural schematic diagram of a drug infusion device provided by the embodiment one of the present application, the drug infusion device comprises: a shell 210, a motor 220, an infusion pipeline 230, a first pump piece 240, a squeezing pump piece group 250 and a second pump piece 260 which are sequentially arranged on the infusion pipeline path and connected with the motor 220, a detection component 270 arranged on the infusion pipeline path, and a data processor 280 connected with the detection component 270. The detection component 270 detects the state parameters of the infusion pipeline 230 and sends the detected state parameters to the data processor 280; the data processor 280 determines whether the infusion pipeline of the drug infusion device is blocked according to the first state parameters detected by the detection component 270 in the first infusion stage and / or the second state parameters detected by the detection component 270 in the second infusion stage. It is to be noted that, Figure 2a The structure of the drug infusion device is only an example, especially the setting position of the detection component 270 is not limited. Further, the data processor 280 outputs the 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 blockage information can further prompt that the pipeline is not blocked, so as to be read by the user. In some embodiments, the data processor 280 can output the identification for representing “blockage” and “non-blockage”, for example, 1 and 0, wherein 1 represents that the infusion pipeline is blocked, and 0 represents that the infusion pipeline is not blocked. Of course, in addition to the identification, the output blockage detection information can also be in the form of one or a combination of text, graphics, symbols, colors, voice, etc.

[0033] The first pump piece 240, the squeezing pump piece group 250 and the second pump piece 260, and the local infusion pipeline 230 are arranged inside the shell 210. Among them, the first pump piece 240, the squeezing pump piece group 250 and the second pump piece 260 are respectively connected with the motor 220.

[0034] One end of the motor 220 is connected with the infusion pipeline 230, the infusion pipeline 230 is a pipeline for conveying medicine, the infusion pipeline 230 is connected with an external storage component, the other end of the motor 220 is connected with another infusion pipeline, the other infusion pipeline is connected into a body of an infusion subject, and the medicine is pumped into the infusion subject from the outside, and the infusion subject can include but is not limited to a human body, an animal body and the like. The first pump sheet 240 controls the medicine to flow into the medicine infusion device. The squeeze pump sheet group 250 can be a squeeze pump sheet or a pump sheet group formed by a plurality of squeeze pump sheets, and can squeeze the medicine to be conveyed. The second pump sheet 260 controls the medicine to flow out of the medicine infusion device. The structure of the first pump sheet 240, the second pump sheet 260 and each squeeze pump sheet in the squeeze pump sheet group is not limited herein, and the structures of the above pump sheets can be the same or different.

[0035] The state parameter of the infusion pipeline 230 can be a state parameter for characterizing a flow process of the medicine in the infusion pipeline, and is used for judging whether the infusion pipeline is blocked. The detection component 270 detects the state of the infusion pipeline 230, including detecting the state parameter of the infusion pipeline in the first infusion stage, the second infusion stage and the first infusion stage and the second infusion stage in the same cycle. Correspondingly, the detected state parameter in the first infusion stage is the first state parameter, and the detected state parameter in the second infusion stage is the second state parameter.

[0036] The state parameters detected in different infusion stages are used for characterizing the liquid flow state of different pipeline regions of the infusion pipeline 230, wherein the different pipeline regions of the infusion pipeline 230 can include an upper end pipeline region and a lower end pipeline region relative to the detection component 270, and the upper end pipeline region and the lower end pipeline region are determined based on the liquid flow direction. Through the detection of the state parameters in different infusion stages, the blockage detection of the different pipeline regions of the infusion pipeline 230 is realized. The first infusion stage can be an infusion intermittent stage of the infusion cycle, and the second value stage can be an infusion stage of the infusion cycle.

[0037] On the basis of the above embodiment, the detection component 270 can be installed at different positions on the infusion pipeline path. For example, referring to Figure 2a- Figure 2e , Figure 2a- Figure 2e respectively, the structural diagrams of the medicine infusion states provided by the embodiments of the present application, wherein the detection component 270 is respectively arranged at different positions on the infusion pipeline. In some embodiments, the detection component 270 can be arranged on the infusion pipeline path between the first pump sheet 240 and the squeeze pump sheet group 250, for example, referring to Figure 2b In some embodiments, the detection component 270 is arranged on the infusion pipeline path between the squeeze pump sheet group 250 and the second pump sheet 260, for example, referring to Figure 2a In some embodiments, the detection component 270 is arranged on the squeeze pump sheet group 250, for example, referring to Figure 2cIn some embodiments, the detection component 270 is arranged on the first pump plate 240, for example, see Figure 2d In some embodiments, the detection component 270 is arranged on the second pump plate, for example, see Figure 2e .

[0038] Based on the above any structure of the drug infusion device, 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.

[0039] 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 pipeline. Specifically, it can be based on one or more cycles of the first state parameter in the first infusion stage to determine whether the upper end of the infusion pipeline of the drug infusion device is blocked; Or, it can be based on one or more cycles of the second state parameter in the second infusion stage to determine whether the lower end of the drug infusion device is blocked, or it can be based on one or more cycles of the first state parameter in the first infusion stage and the second state parameter in the second infusion stage to determine whether the upper end and the lower end of the drug infusion device are blocked.

[0040] The technical scheme of the embodiment provides a drug infusion device, detects the state parameters of the infusion pipeline through the detection device installed on the infusion pipeline path, sends the detected state parameters of the infusion pipeline to the data processor for processing, and finally determines the blockage of the infusion pipeline. The purpose of diversifying the detection method, reducing the cost and simplifying the structure is achieved. In the case of detecting the blockage of the infusion pipeline in the drug infusion device, the blockage prompt information can be generated to facilitate the operator to check the drug infusion device to ensure the normal infusion of the drug.

[0041] In the above embodiments, different types of detection components can be used to detect the state parameters of the infusion pipeline 230, and accordingly, different types of state parameters can be detected. Specifically, any type of detection component can detect the corresponding type of first state parameter in the first infusion stage and / or the corresponding type of second state parameter in the second infusion stage. In this embodiment, one or more types of state parameters can be used to determine whether the infusion pipeline of the drug infusion device is blocked. Here, different types of state parameters can correspond to different determination rules, and accordingly, the data processor 280 stores the determination rules corresponding to the types of detection components, which realizes the determination of whether the infusion pipeline is blocked.

[0042] Optionally, the detection component 270 can 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 provided in the drug infusion state, and the infusion pipeline can be determined to be blocked by multiple types of state parameters. The determination results of different types of state parameters on the infusion pipeline are cross-verified, and the correctness of the determination result is improved.

[0043] The pressure detection component is configured to detect the pressure borne by the infusion pipeline. The pressure detection component can be a pressure sensor or other device for detecting pressure. When the drug flows through the infusion pipeline, the drug generates pressure on the infusion pipeline 230. Correspondingly, when the infusion pipeline 230 is blocked, the pressure generated on the infusion pipeline 230 is also different. For example, in the first infusion stage, when the upper pipeline region is blocked, the drug cannot flow into the infusion pipeline 230, resulting in a small pressure generated on the infusion pipeline 230. In the second infusion stage, when the lower pipeline region is blocked, the drug cannot flow out of the infusion pipeline 230, resulting in a large pressure generated on the infusion pipeline 230.

[0044] The pressure detection component detects the pressure of the drug on the infusion pipeline 230. Correspondingly, the first state parameter is a first pressure value, and the second state parameter is a second pressure value.

[0045] The distance detection component is configured to detect the displacement of the drug inside the infusion pipeline. The distance detection component can be a distance sensor, an ultrasonic sensor, or other device for detecting distance. During the process of the drug flowing through the infusion pipeline 230, the displacement of the drug inside the infusion pipeline 230 is detected. Here, the displacement can be the displacement in the vertical direction along the liquid flow direction. Correspondingly, when the infusion pipeline 230 is blocked, the displacement of the drug in the infusion pipeline 230 is also different. For example, in the first infusion stage, when the upper pipeline region is blocked, the drug cannot flow into the infusion pipeline 230, and the drug in the infusion pipeline 230 is less, resulting in a decrease in the displacement of the drug in the infusion pipeline 230. In the second infusion stage, when the lower pipeline region is blocked, the drug cannot flow out of the infusion pipeline 230, and the drug in the infusion pipeline 230 is more, resulting in a large displacement of the drug in the infusion pipeline 230.

[0046] 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 a first displacement value, and the second state parameter is a second displacement value.

[0047] The deformation detection component is configured to detect whether the infusion pipeline is deformed. The deformation detection component can be a deformation sensor or other device configured to detect deformation. During the flow of the drug through the infusion pipeline 230, the drug changes the state of the infusion pipeline 230. Accordingly, in the case of an obstruction in the infusion pipeline 230, the deformation of the infusion pipeline 230 caused by the drug is different. Here, deformation includes concave and convex deformation of the infusion pipeline 230. For example, in the first infusion stage, in the case of an obstruction in the upper end pipeline region, the drug cannot flow into the infusion pipeline 230, and the infusion pipeline 230 has less drug, which causes the infusion pipeline 230 to have a concave deformation. In the second infusion stage, in the case of an obstruction in the lower end pipeline region, the drug cannot flow out of the infusion pipeline 230, and the infusion pipeline 230 has more drug, which causes the infusion pipeline 230 to have a convex deformation. The deformation detection component detects a first deformation value and a second deformation value in different infusion stages. It should be noted that the deformation value can be positive or negative. For example, a positive deformation value represents a convex deformation value, and a negative deformation value represents a concave deformation value.

[0048] The liquid flow detection component is configured to detect the liquid flow state of the infusion pipeline. The liquid flow detection component can be a liquid flow sensor or other device configured to detect the liquid flow state. When the drug flows through the infusion pipeline 230, the liquid flow state of the infusion pipeline 230 is detected by the liquid flow detection component. The liquid flow state can include whether the liquid is flowing or not, or the liquid flow state can include the flow speed. When the state of the infusion pipeline changes, the liquid flow state of the infusion pipeline also changes accordingly. For example, in the case of an obstruction in the infusion pipeline 230, the liquid does not flow or the liquid flow speed is low, and in the case of no obstruction, the liquid flow speed is high.

[0049] Accordingly, the first state parameter can be a first flow speed, and the second state parameter can be a second flow speed.

[0050] On the basis of the above-described embodiments, the data processor 280 is configured to determine the obstruction of the infusion pipeline according to one or more detected first state parameters and / or second state parameters. The first state parameter and the second state parameter can be state parameters detected by any of the above-described detection components 270. For example, in the case of a pressure detection component as the detection component 270, the values of the first state parameter and the second state parameter are pressure values detected by the pressure detection component. For example, in the case of a distance detection component as the detection component 270, the values of the first state parameter and the second state parameter are distance values detected by the distance detection component. For example, in the case of a deformation detection component as the detection component 270, the values of the first state parameter and the second state parameter are the direction of deformation and the specific deformation amount detected by the deformation detection component. For example, in the case of a liquid flow detection component as the detection component 270, the values of the first state parameter and the second state parameter are flow speed values detected by the liquid flow detection component.

[0051] The detection component 270 can detect the state parameter of the infusion pipeline 230 in real time, and send the detected state parameter to the data processor 280. Alternatively, the detection component 270 can detect the state parameter of the infusion pipeline 230 in the current period or the next period after receiving the detection instruction. The data processor 280 can determine whether the infusion pipeline is blocked according to the detection state parameter of one period, multiple periods, for example, processing the state parameter obtained in multiple detection periods to determine whether the infusion pipeline is blocked, and can also process the state parameter obtained in each period to determine whether the infusion pipeline is blocked. Alternatively, the data processor 280 can be configured to process a preset number of detection periods, and determine whether the infusion pipeline is blocked according to the state parameter obtained in the preset number of periods.

[0052] In some embodiments, the data processor 280 determines the blockage of the infusion pipeline according to the detected first state parameter and / or second state parameter and the corresponding preset threshold. For example, the blockage of the infusion pipeline is determined based on the first state parameter and the first threshold. Alternatively, the blockage of the infusion pipeline is determined based on the second state parameter and the second threshold. Alternatively, the blockage of the infusion pipeline is determined based on the first state parameter, the second state parameter and the third threshold.

[0053] The first state parameter and the first threshold value are compared to determine the occlusion of the infusion pipeline, including: in the case that the first state parameter meets the first threshold value comparison condition, it is determined that the upper pipeline region of the drug infusion device is not occluded; in the case that the first state parameter does not meet the first threshold value comparison condition, it is determined that the upper pipeline region of the drug infusion device is occluded. Different types of state parameters correspond to different first threshold values and / or different first threshold value comparison conditions. For example, in the case that the first pressure value is greater than the first pressure threshold value, it is determined that the first threshold value comparison condition is met, i.e., the upper pipeline region of the drug infusion device is not occluded; in the case that the first pressure value is less than the first pressure threshold value, it is determined that the first threshold value comparison condition is not met, i.e., the upper pipeline region of the drug infusion device is occluded. For example, in the case that the first displacement value is greater than the first displacement threshold value, it is determined that the first threshold value comparison condition is met, i.e., the upper pipeline region of the drug infusion device is not occluded; in the case that the first displacement value is less than the first displacement threshold value, it is determined that the first threshold value comparison condition is not met, i.e., the upper pipeline region of the drug infusion device is occluded. For example, in the case that the first flow velocity is greater than the first flow velocity threshold value, it is determined that the first threshold value comparison condition is met, i.e., the upper pipeline region of the drug infusion device is not occluded; in the case that the first flow velocity value is less than the first flow velocity threshold value, it is determined that the first threshold value comparison condition is not met, i.e., the upper pipeline region of the drug infusion device is occluded. For example, in the case that the first deformation value is positive deformation and the first deformation value is greater than the first deformation threshold value, it is determined that the first threshold value comparison condition is met, i.e., the upper pipeline region of the drug infusion device is not occluded; in the case that the first deformation value is less than the first deformation threshold value, it is determined that the first threshold value comparison condition is not met, i.e., the upper pipeline region of the drug infusion device is occluded.

[0054] The determination of the blockage of the infusion pipeline based on the second state parameter and the second threshold value includes a comparison of the second state parameter with the second threshold value, and in the case that the second state parameter meets the comparison condition of the second threshold value, it is determined that the lower pipeline region of the drug infusion device is not blocked, and in the case that the second state parameter does not meet the comparison condition of the second threshold value, it is determined that the lower pipeline region of the drug infusion device is blocked. Different types of state parameters correspond to different second threshold values and / or different comparison conditions of the second threshold value. For example, in the case that the second pressure value is greater than the second pressure threshold value, it is determined that the comparison condition of the second threshold value is not met, i.e., the lower pipeline region of the drug infusion device is blocked, and in the case that the second pressure value is less than the second pressure threshold value, it is determined that the comparison condition of the second threshold value is met, i.e., the lower pipeline region of the drug infusion device is not blocked. For example, in the case that the second displacement value is greater than the second displacement threshold value, it is determined that the comparison condition of the second threshold value is not met, i.e., the lower pipeline region of the drug infusion device is blocked, and in the case that the second displacement value is less than the second displacement threshold value, it is determined that the comparison condition of the second threshold value is met, i.e., the lower pipeline region of the drug infusion device is not blocked. For example, in the case that the second flow velocity is greater than the second flow velocity threshold value, it is determined that the comparison condition of the second threshold value is met, i.e., the lower pipeline region of the drug infusion device is not blocked, and in the case that the second flow velocity value is less than the second flow velocity threshold value, it is determined that the comparison condition of the second threshold value is not met, i.e., the lower pipeline region of the drug infusion device is blocked. For example, in the case that the second deformation value is positive deformation and greater than the second deformation threshold value, it is determined that the comparison condition of the second threshold value is not met, i.e., the lower pipeline region of the drug infusion device is blocked, and in the case that the second deformation value is negative deformation and less than the second deformation threshold value, it is determined that the comparison condition of the second threshold value is met, i.e., the lower pipeline region of the drug infusion device is not blocked.

[0055] The determination of the infusion pipeline blockage based on the first state parameter, the second state parameter and the third threshold value comprises: comparing the parameter sum of the first state parameter and the second state parameter with the third threshold value, and determining whether the infusion pipeline is blocked according to the comparison result. Taking the pressure value as the state parameter, in the case that the pressure sum of the first pressure value and the second pressure value is greater than the third pressure threshold value, it is determined that the lower end pipeline region of the infusion pipeline is blocked, and in the case that the pressure sum of the first pressure value and the second pressure value is less than the third pressure threshold value, it is determined that the upper end pipeline region of the infusion pipeline is blocked. Taking the deformation value as the state parameter, in the case that the deformation sum of the first deformation value and the second deformation value is greater than the third deformation threshold value, it is determined that the lower end pipeline region of the infusion pipeline is blocked, and in the case that the deformation sum of the first deformation value and the second deformation value is less than the third deformation threshold value, it is determined that the upper end pipeline region of the infusion pipeline is blocked. Taking the displacement value as the state parameter, in the case that the displacement sum of the first displacement value and the second displacement value is greater than the third displacement threshold value, it is determined that the lower end pipeline region of the infusion pipeline is blocked, and in the case that the displacement sum of the first displacement value and the second displacement value is less than the third displacement threshold value, it is determined that the upper end pipeline region of the infusion pipeline is blocked. Taking the liquid flow state as the state parameter, in the case that the velocity sum of the first flow velocity and the second flow velocity is greater than the third velocity threshold value, it is determined that there is no blockage in the infusion pipeline, and in the case that the velocity sum of the first flow velocity and the second flow velocity is less than the third velocity threshold value, it is determined that there is a blockage in the infusion pipeline.

[0056] In some embodiments, the data processor 280 can determine the infusion pipeline blockage according to the changes of the first state parameter and / or the second state parameter detected multiple times. Specifically, the data processor 280 can determine the parameter change according to the first state parameter and / or the second state parameter detected multiple times, and determine the infusion pipeline blockage of the drug infusion device 230 based on the parameter change.

[0057] The data processor 280 can determine the infusion pipeline 230 blockage according to the changes of the detected state parameter in multiple periods. For example, the difference between the current state parameter and the corresponding state parameter in other periods can be represented as the change of the state parameter, and correspondingly, the change of the state parameter can include the difference between the state parameter in the current period and the state parameter in multiple other periods, wherein the number of other periods is at least one. The change of the state parameter can also be represented by the change of the difference between two adjacent times, or can also be represented by the slope of the change of the state parameter. Specifically, the change of the state parameter can be compared with a preset threshold value, etc. 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, and the parameter sum change of the first state parameter and the second state parameter. The above-mentioned first state parameter and second state parameter can be any one of the parameter types of pressure value, deformation value, displacement value and liquid flow state.

[0058] In a case where the change in the first state parameter does not meet the parameter change condition, it is determined that the upper end pipeline region of the infusion pipeline is blocked. Specifically, in a case where each difference in the change in the first state parameter is greater than the first difference threshold, it is determined that the upper end pipeline region of the infusion management is blocked. In a case where the change in the second state parameter does not meet the parameter change condition, it is determined that the lower end pipeline region of the infusion management is blocked, specifically, in a case where each difference in the change in the second state parameter is greater than the second difference threshold, it is determined that the lower end pipeline region of the infusion management is blocked. In a case where each parameter and difference in the parameter and change of the first state parameter and the second state parameter is greater than the third difference threshold, it is determined that the lower end pipeline region of the infusion management is blocked, and in a case where each parameter and difference is less than the fourth difference threshold, it is determined that the upper end pipeline region of the infusion management is blocked.

[0059] In the embodiment, the data processor 280 is further configured to verify based on the multiple detections of the blockage, and in a case where a continuous verification condition is met, it is determined that the infusion pipeline of the drug infusion device is blocked. The verification times can be pre-set, for example, 3 times can be set, and the continuous verification condition can be pre-set as the continuous verification times detecting the infusion pipeline blockage. In a case where the continuous verification condition is met, it is determined that the infusion pipeline is blocked, and in a case where the continuous verification condition is not met, it is determined that the infusion pipeline is not blocked. The blockage of the infusion pipeline can be caused by external factors such as manual pressing and misoperation, and after the external interference is excluded, the blockage is confirmed again.

[0060] The technical scheme provided by the embodiment of the application avoids the accidental misdetection, thereby improving the accuracy of the determination of the blockage of the infusion pipeline.

[0061] On the basis of the above-mentioned embodiment, the embodiment one of the application further provides an example of a drug infusion device, and the drug infusion device selects a portable infusion pump.

As shown in the figure. Figure 3 Figure 3 The portable infusion pump comprises three pump pieces, and the three pump pieces have a certain interval distance, and the pressure sensor can be located in the interval between any two pump pieces.

[0062] The portable infusion pump is in an intermittent infusion mode, and the pressure sensor can detect the upper blockage pressure, i.e., the first state parameter, during the infusion interval. During the infusion process, the pressure sensor can detect the lower blockage pressure, i.e., the second state parameter.

[0063] The portable infusion pump is in an intermittent infusion mode, and the pressure sensor can detect the upper blockage pressure, i.e., the first state parameter, during the infusion interval. During the infusion process, the pressure sensor can detect the lower blockage pressure, i.e., the second state parameter.

[0064] ​The data processor determines the blockage based on the upper blockage pressure and / or the lower blockage pressure collected by the pressure sensor, and the determination method 1 of the upper and lower blockage pressures is as follows: an analog-to-digital converter is arranged in the pressure sensor to convert the collected analog pressure value into a digital pressure value, i.e., an AD value; when the upper blockage pressure is measured, the real-time read AD value is compared with the upper blockage pressure AD threshold value set in the register, and if the AD value is lower than the AD threshold value, it is determined that the upper blockage occurs; when the lower blockage pressure is measured, the real-time read AD value is compared with the lower blockage pressure AD value set in the register, and if the AD value is higher than the AD threshold value, it is determined that the lower blockage occurs.

[0065] The determination method 2 of the upper and lower blockage pressures is as follows: the pressure sensor converts the pressure value into an AD value; when the upper blockage pressure is measured, the real-time read AD value is stored in the register, and the value is compared with the AD values read within a set number of times, and if the difference is greater than a set value, it is determined that the upper blockage occurs, and the AD values before the set number of times can be deleted in the register; when the lower blockage pressure is measured, the real-time read AD value is stored in the register, and the value is compared with the AD values read within a set number of times, and if the difference is greater than a set value, it is determined that the lower blockage occurs, and the AD values before the set number of times can be deleted in the register.

[0066] The determination method 3 of the upper and lower blockage pressures is as follows: the pressure sensor converts the pressure value into an AD value, sums the upper and lower blockage pressure AD values read in the same infusion cycle, and if the sum is greater than the threshold value set in the register, it is determined that the lower blockage occurs; if the sum is less than the threshold value set in the register, it is determined that the upper blockage occurs (considering a single fault).

[0067] The determination method 4 of the upper and lower blockage pressures is as follows: the pressure sensor converts the pressure value into an AD value, sums the upper and lower blockage pressure AD values read in the same infusion cycle, and compares the AD values read within a set number of times, and if the difference is greater than a set value, it is determined that the lower blockage occurs, and if the difference is less than a set value, it is determined that the upper blockage occurs, and the AD values before the set number of times can be deleted in the register.
