A movable plate 408 is provided on the front surface of the box body 402 and is located below the display screen 401. The meter 4 is opened through the movable plate 408 to facilitate the maintenance of the microcontroller 405 and the battery 406, and it is also convenient to charge the battery 406 for detection and monitoring of the meter 4.

[0063] In this embodiment, if Figure 6As shown, speed detection plates 9 are provided on the upper and lower inner walls of the tube hole 40202, and the detection data is received by the control module. Two upper and lower symmetrical grooves 10 are provided in the box body 402, and the backs of the two speed detection plates 9 are movably connected with threaded rods 901, and the upper ends of the two threaded rods 901 are movably connected with driving members 1001, and the two driving members 1001 are fixedly connected to the grooves 10, and the two threaded rods 901 are movably connected to the driving members 1001, and the two threaded rods 901 are movably connected to the speed detection plates 9. The two speed detection plates 9 located in the tube hole 40202 can detect and monitor the liquid flow in the infusion tube 1 from the infusion end, and one of the speed detection plates 9 is used to detect whether there is liquid in the tube. , which is convenient for avoiding irreversible danger caused by the input of air into the patient's body, and the other is for detecting the flow rate of the liquid in the infusion tube, so as to adjust the flow rate in the tube as needed, or to cut off the infusion state of the infusion tube 1 from the end of the meter 4 after the infusion is completed, so as to avoid the medical staff failing to find out in time that the liquid in the tube has been output. The threaded rod 901 on the back of the speed detection plate 9 is arranged to adjust the distance between them according to the diameter of the tube, and the threaded rod 901 is based on the driving member 1001 to adjust the distance between it and the threaded rod. As shown in the figure, the threaded rod 901 is embedded with the rotating rod at the front end of the driving member 1001, so the position inside can be adjusted, thereby adjusting the threaded rod 901 to move forward to control the speed detection plate 9 to move toward the middle.

[0064] In this embodiment, if Figure 7 and 8As shown, the inner wall of the tube hole 40202 is provided with grooves 11 at the upper and lower sides, and the two grooves 11 are provided with speed control plates 12 and 13, and both are movably connected with the grooves 11. The box body 402 is provided with two grooves 1101 at the upper and lower sides, and the two grooves 1101 are provided with drive components 14. The two drive components 14 include two drive parts 1401, two drive parts 1402 and four threaded rods 1403. Each of the two threaded rods 1403 is movably connected. The two drive members 1401 and the three drive members 1402 are electrically connected to the threaded rod 1403, and the two drive members 1401 and the three drive members 1402 are fixedly connected to the groove 3 1101. The lower end of the speed control plate 12 is provided with a convex block 1201, and the upper end of the speed control plate 2 13 is provided with a groove 4 1301, and both are movably connected to the convex block 1201. The speed control plate 12 and the speed control plate 2 13 are located at two inspection positions. The speed detection plate 9 is located behind the speed plate 9 and at the end of the meter 4, so that the front end speed detection plate 9 detects that the liquid in the tube is not in a state of continuing to flow, and sends an instruction to the control module, so that the microcontroller 405 starts the driving member 3 1402 and the driving member 2 1401 to start the activity, and drives the threaded rod 2 1403 below to rotate, and adjusts the distance between it and the driving member 3 1402 and the driving member 2 1401. As shown in the figure, since the rotating rod at the front end of the driving member 3 1402 and the driving member 2 1401 is embedded with the threaded rod 2 1403, the position of the threaded rod 2 1403 in the rotating rod can be controlled, thereby controlling the distance between the speed control plate 1 12 and the speed control plate 2 13, thereby adjusting the flow rate in the liquid tube, the protrusion 1201 set on the speed control plate 12 and the groove 4 1301 of the speed control plate 2 13 are stuck and connected, so that the flow of the liquid in the infusion tube 1 can be cut off, and air is prevented from entering the patient's body with the pressure of the infusion to cause irreversible consequences.

[0065] In this embodiment, if Fig. 9As shown, the control module includes: a flow detection module, which is used to monitor whether there is liquid flow in the infusion tube 1 through one of the speed detection plates 9 located in the meter 4, and feed back the detected data to the flow detection module, and the data is fed back to the control module through the flow detection module, and the control module displays the data on the display screen 401 to show whether the liquid is in a delivery state; a pressure detection module, which is used to monitor and detect the infusion flow rate in the infusion tube 1 through another speed detection plate 9, and feed back the detected data to the pressure detection module, and the pressure detection module gives the data to the control module. The control module sends instructions to the microcontroller 405 to send specific data to the display screen 401 to display the current flow rate; the control module includes: a speed control module, which is used for: receiving the flow rate of the infusion tube 1 by the control module, and when it is detected that the flow rate in the infusion tube 1 is zero, that is, when the infusion is finished, the speed control module controls the speed control plate 12 and the speed control plate 2 13 located at the upper and lower ends of the tube hole 40202 of the meter 4 to move to the middle respectively, clamping the infusion tube 1 to stop the infusion, and when it is necessary to adjust the flow rate in the infusion tube 1, the distance between the speed control plate 12 and the speed control plate 2 13 can be adjusted through the speed control module.

[0066] Working principle: When it is necessary to use an external pressure infusion device, insert the upper regulator 2 at the front end of the infusion tube 1 used to match the metered infusion device into the liquid bag, and the medical staff inserts the needle at the end of the infusion tube 3 7 into the patient's blood vessel to start infusion. At this time, remove the left clamping tube 802 at the front end of the meter 4 from one side of the right clamping tube 801, and remove the clamping strip 403 from one side of the box body 402. Then, insert the infusion tube 1 into the opening 804 and the tube hole 40202 respectively, and then insert the left clamping tube 802 into the clamping slot 4 806 of the right clamping tube 801 through the clamping block 2 805, and the clamping strip 403 into the clamping slot 3 407 on one side of the box body 402 through the clamping block 1 40301. At this time, turn on the meter 4 through the button on the side of the display screen 401, which is now located in the box body 402. The two speed detection plates 9 first adjust the distance between them according to the diameter of the infusion tube 1, clamp the infusion tube 1 and monitor and detect the infusion flow rate in the tube and whether the infusion is in progress. If it is necessary to adjust the flow rate in the infusion tube 1, the distance between the speed control plate 1 12 and the speed control plate 2 13 located at the rear can be used for regulation. The speed control plate 1 12 and the speed control plate 2 13 are respectively driven by the driving member 3 1402 and the driving member 2 1401 to adjust the forward distance, thereby regulating the flow rate. If the speed detection plate 9 detects that there is no infusion state inside, the protrusion 1201 of the speed control plate 12 and the groove 4 1301 of the speed control plate 2 13 are stuck and connected to cut off the flow of the liquid in the infusion tube 1, thereby preventing air from entering the patient's body with the pressure of the infusion and causing irreversible consequences.

[0067] Specifically, the control module further includes:

[0068] A real-time monitoring module, used for real-time monitoring the length of time it takes for the flow detection module to send each data to the control module;

[0069] The first delay evaluation coefficient acquisition module is used to obtain the first delay evaluation coefficient by using the data transmission time length of each data sent by the flow detection module to the control module; wherein the first delay evaluation coefficient is obtained by the following formula:

[0070]

[0071] Among them, S 01 represents the first delay evaluation coefficient; n represents the number of times the flow detection module sends data to the control module; V s01i represents the data transmission rate of the ith data transmission of the flow detection module; V e01 represents a preset reference data transmission rate value for data transmission from the flow detection module to the control module; T s01i represents the actual data transmission duration of the ith data transmission of the flow detection module; T 01i Indicates the maximum permissible duration of data transmission for the ith data transmission of the flow detection module under normal transmission conditions;

[0072] A comparison module, used for comparing the first delay evaluation coefficient with a preset evaluation coefficient threshold;

[0073] An abnormality alarm module, used for issuing a data communication abnormality alarm when the first delay evaluation coefficient exceeds a preset evaluation coefficient threshold;

[0074] The data transmission rate adjustment module is used to adjust the data transmission rate of the pressure detection module to the control module by using the first delay evaluation coefficient when the first delay evaluation coefficient does not exceed a preset evaluation coefficient threshold.

[0075] The technical effect of the above technical solution is that through the real-time monitoring module, the technical solution can track and record the length of time the flow detection module sends data to the control module in real time. This function is crucial for evaluating the real-time and efficiency of data transmission, and helps to promptly discover potential data transmission delay problems.

[0076] The first delay evaluation coefficient acquisition module is used to accurately calculate the first delay evaluation coefficient (S01) through a complex calculation formula (involving multiple factors such as the number of data transmissions, the actual transmission rate, the reference transmission rate, the actual transmission duration, and the maximum allowed duration). This coefficient can fully reflect the delay and efficiency of data transmission and provide a basis for subsequent decision-making.

[0077] The comparison module compares the calculated first delay evaluation coefficient with the preset evaluation coefficient threshold. When the delay evaluation coefficient exceeds the threshold, the abnormal alarm module immediately triggers the data communication abnormal alarm. This intelligent decision-making mechanism can quickly respond to abnormal situations in data transmission and ensure the stability and security of the system.

[0078] When the delay evaluation coefficient does not exceed the preset threshold, the data transmission rate adjustment module dynamically adjusts the data transmission rate from the pressure detection module to the control module according to the first delay evaluation coefficient. This adjustment mechanism helps to optimize data transmission efficiency, reduce unnecessary resource consumption, and maintain the stability and real-time performance of data transmission.

[0079] Through the collaborative work of the above modules, this technical solution can significantly improve the overall performance of the system. It can not only effectively reduce data transmission delays and anomalies, but also dynamically adjust the data transmission rate according to actual conditions, thereby ensuring that the system can maintain efficient and stable operation under various working conditions.

[0080] In summary, this technical solution effectively improves the efficiency and stability of data transmission through mechanisms such as real-time monitoring, accurate evaluation, intelligent decision-making and dynamic adjustment, providing strong support for improving the overall performance of the system.

[0081] Specifically, the data transmission rate adjustment module includes:

[0082] A duration data extraction module, used to extract the data transmission time length of each data transmission from the pressure detection module to the control module;

[0083] The second delay evaluation coefficient acquisition module is used to obtain the second delay evaluation coefficient by using the data sending time length of each data sent by the pressure detection module to the control module; wherein the second delay evaluation coefficient is obtained by the following formula:

[0084]

[0085] Among them, S 02 represents the second delay evaluation coefficient; m represents the number of times the pressure detection module sends data to the control module; V s02i represents the data transmission rate of the i-th data transmission of the pressure detection module; V e02 represents the preset reference data transmission rate value for data transmission from the pressure detection module to the control module; T s02i represents the actual data transmission duration of the i-th data transmission of the pressure detection module; T 02i Indicates the maximum permissible duration of data transmission for the i-th data transmission of the pressure detection module under normal transmission conditions;

[0086] The delay evaluation comprehensive coefficient acquisition module is used to obtain the delay evaluation comprehensive coefficient by using the first delay evaluation coefficient and the second delay evaluation coefficient; wherein the delay evaluation comprehensive coefficient is obtained by the following formula:

[0087]

[0088] Where S represents the comprehensive coefficient of delay evaluation; S 01 Represents the first delay evaluation coefficient; S 02 represents the second delay evaluation coefficient;

[0089] The data transmission rate adjustment module is used to obtain the adjusted data transmission rate using the delay evaluation comprehensive coefficient; wherein the data transmission rate is obtained by the following formula:

[0090]

[0091]

[0092] Among them, V 02t Represents the adjusted data transmission rate; V s02i represents the data transmission rate of the i-th data transmission of the pressure detection module; V e02 represents the preset reference data transmission rate value for data transmission from the pressure detection module to the control module; m represents the number of data transmissions from the pressure detection module to the control module; S represents the delay evaluation comprehensive coefficient; F represents the compensation coefficient; n represents the number of data transmissions from the flow detection module to the control module; V s01i represents the data transmission rate of the ith data transmission of the flow detection module; V e01 Indicates a preset reference data transmission rate value for data transmission from the flow detection module to the control module;

[0093] The adjustment execution module is used to adjust the data transmission rate of the pressure detection module according to the adjusted data transmission rate.

[0094] The technical effect of the above technical solution is: by real-time monitoring and calculating the data transmission efficiency (including the length of data transmission time, etc.) from the pressure detection module to the control module, the technical solution can dynamically adjust the data transmission rate. This dynamic adjustment mechanism helps to optimize the data transmission efficiency and reduce the delay and packet loss rate of data transmission according to the actual network conditions, equipment load and other factors during the data transmission process.

[0095] By introducing the second delay evaluation coefficient (S02), the solution not only considers the relationship between the actual data transmission duration and the maximum allowed duration, but also combines the difference between the data transmission rate and the reference rate, so as to more comprehensively evaluate the data transmission delay. This comprehensive evaluation method helps to more accurately determine potential problems in the data transmission process, and adjust the data transmission rate accordingly, thereby improving the response speed and stability of the system.

[0096] When obtaining the adjusted data transmission rate, the scheme not only considers the data transmission situation of the pressure detection module (such as Vs02 i, Ve02, m, etc.), but also introduces the data transmission information of the flow detection module (such as Vs01 i, Ve01, n, etc.), and comprehensively considers it through the compensation coefficient F. This multi-source data fusion method helps to understand the data transmission status of the system more comprehensively, so as to make more reasonable adjustment decisions.

[0097] Since the solution adopts a modular design concept, including multiple independent modules such as duration data extraction module, second delay evaluation coefficient acquisition module, delay evaluation comprehensive coefficient acquisition module, etc., it can be flexibly configured and expanded according to specific needs in actual applications. For example, according to the characteristics of different devices or the needs of application scenarios, the parameters of each module can be adjusted or new modules can be introduced to enhance the functions of the system.

[0098] By optimizing the data transmission rate and reducing delays and packet loss during data transmission, this technical solution can improve the user experience when using related devices or systems. This technical solution can play a positive role in both application scenarios with high real-time requirements (such as industrial automation control, telemedicine, etc.) and scenarios with high data transmission stability requirements (such as financial transactions, online education, etc.).
