TECHNICAL FIELD
[0001] The present application relates to the technical field of medical teaching equipment, and in particular to a simulation interaction quality assessment system and method for intravenous infusion. BACKGROUND
[0002] With the rapid development of modern medical technology and the continuous progress of nursing education, intravenous infusion, as a basic professional technique that nurses must master, has become increasingly important. Intravenous infusion is mainly used to infuse fluids, drugs, and other substances into patients to achieve various purposes such as drug therapy, fluid replacement, and nutritional support. Traditional intravenous infusion teaching usually relies on actual patients or manikins for practice, but this approach has many limitations. To address these issues, virtual simulation teaching systems for intravenous infusion have emerged. These systems use advanced virtual reality technology to create realistic intravenous infusion scenarios, allowing students to practice intravenous puncture, infusion device setup and maintenance, and other operations in a simulated environment. The system can simulate various clinical scenarios, including different patient vein conditions, infusion reactions, and possible complications, helping students master coping strategies in different situations.
[0003] Existing technologies use multifunctional injection models or intravenous injection simulation arms equipped with simulated blood systems (such as 6 closed rubber catheters, rotatable modules) to record data such as puncture force, infusion speed, and fixation stability through built-in sensors in the manikin, and evaluate puncture accuracy, fixation stability, and sterile operation compliance.
[0004] For example, the patent application with publication number CN116580609A discloses a virtual medical teaching system based on multi-person interaction and its construction method, which includes: constructing medical teaching scene models under each preset scene mode according to material data, and logically interacting with the medical teaching scene models to make the medical teaching scene models realize environment simulation, obtaining medical teaching scenes under each preset scene mode; obtaining the target scene mode and target scene name of the current user, and determining the target medical teaching scene in the medical teaching scene according to the target scene mode and target scene name; presenting the target medical teaching scene to the current user to make the current user operate in the target medical teaching scene; obtaining scene operation data of the current user in the target medical teaching scene, and rendering and sending the scene operation data to the target user to make the target user interact with the current user.
[0005] For example, the patent application with publication number CN118135852A discloses a medical training method, device and equipment based on virtual reality and a storage medium, which comprises the following steps: obtaining login information of a target student; loading a preset medical training scene according to the login information; transmitting the medical training scene to a visual interface of a VR device, so that the target student operates the VR device to train in the medical training scene; receiving interaction data for the medical training scene; and comparing the interaction data with preset standardized data to obtain training evaluation data of the target student.
[0006] However, in the process of implementing the technical scheme of the embodiments of the present application, the applicant found that the above-mentioned technology at least has the following technical problems:
[0007] The existing simulation training device uses a sensor to detect the drop speed, but the precision is insufficient. For example, when using infrared transmission principle to detect the drop speed, due to the absorption and scattering of infrared light by the falling liquid medicine, the voltage change output by the sensor is not accurate enough, which affects the accuracy of drop speed detection. In addition, in the drop speed adjustment algorithm, the properties of the liquid medicine, the patient's condition and other factors are not fully considered when adjusting the drop speed, resulting in low drop speed adjustment efficiency in the process of simulating the exhaust and puncture interaction quality evaluation of intravenous infusion. SUMMARY
[0008] The embodiments of the present application provide a simulation interaction quality evaluation system and method for intravenous infusion, which solves the problem of low drop speed adjustment efficiency in the process of simulating the exhaust and puncture interaction quality evaluation of intravenous infusion in the prior art, and improves the drop speed adjustment efficiency in the process of simulating the exhaust and puncture interaction quality evaluation of intravenous infusion.
[0009] The embodiments of the present application provide a simulation interaction quality evaluation system for intravenous infusion, which comprises an exhaust process evaluation module, a puncture process evaluation module and a drop speed adjustment module. The exhaust process evaluation module is used to evaluate the accuracy of the exhaust operation according to the obtained exhaust data, and to determine whether the exhaust operation is completed based on the exhaust operation accuracy. The exhaust data is used to reflect the exhaust state of the specified nursing student in the exhaust interaction process of simulating intravenous infusion. The puncture process evaluation module is used to evaluate the accuracy of the puncture operation based on the obtained puncture data if the exhaust operation is completed, and to determine whether the puncture operation is completed based on the puncture operation accuracy. The puncture data is used to reflect the puncture state of the specified nursing student in the puncture interaction process of simulating intravenous infusion. The drop speed adjustment module is used to adjust the drop speed based on the obtained drop speed adjustment parameter if the puncture operation is completed, and to determine whether the drop speed adjustment is completed. The drop speed adjustment parameter is used to quantify the drop speed adjustment efficiency of the corresponding valve after the completion of the puncture interaction of simulating intravenous infusion by the specified nursing student.
[0010] The embodiment of the application provides a simulation interaction quality evaluation method of intravenous infusion, comprising the following steps: step one, performing exhaust operation accuracy evaluation according to obtained exhaust data, judging whether the exhaust operation is completed based on the exhaust operation accuracy degree, wherein the exhaust data is used for reflecting the exhaust state of the specified nursing student in the exhaust interaction process of the simulated intravenous infusion; step two, if the exhaust operation is completed, performing puncture operation accuracy evaluation based on obtained puncture data, judging whether the puncture operation is completed based on the puncture operation accuracy degree, wherein the puncture data is used for reflecting the puncture state of the specified nursing student in the puncture interaction process of the simulated intravenous infusion; step three, if the puncture operation is completed, performing drip speed adjustment based on obtained drip speed adjustment parameters, judging whether the drip speed adjustment is completed, wherein the drip speed adjustment parameters are used for quantifying the drip speed adjustment efficiency of the corresponding adjusting valve after the puncture interaction of the simulated intravenous infusion is completed.
[0011] The one or more technical solutions provided in the embodiment of the application have at least the following technical effects or advantages:
[0012] 1. The exhaust operation accuracy evaluation is performed through the obtained exhaust data, and whether the exhaust operation is completed is judged based on the exhaust operation accuracy degree; if yes, whether the puncture operation is completed is judged based on the puncture operation accuracy degree; if yes, the drip speed adjustment is performed based on the obtained drip speed adjustment parameters, and whether the drip speed adjustment is completed is judged, so that the improvement of the drip speed adjustment accuracy is realized, and then the improvement of the drip speed adjustment efficiency in the exhaust and puncture interaction quality evaluation process of the simulated intravenous infusion is realized, and the problem of low drip speed adjustment efficiency in the exhaust and puncture interaction quality evaluation process of the simulated intravenous infusion in the prior art is effectively solved.
[0013] 2. The proportion degree of the obtained exhaust operation time length in the total time length of the exhaust period is corrected through the exhaust operation time length weight factor to obtain an exhaust operation time length score, and the results of coupling processing of the needle retention frequency score and the bubble residual amount score are corrected with the exhaust operation time length score to obtain an exhaust operation evaluation value, so that the improvement of the exhaust operation evaluation value acquisition accuracy is realized, and then the more accurate evaluation of the exhaust operation accuracy is realized.
[0014] 3. The proportion degree of the obtained puncture operation time length in the total time length of the puncture period is corrected through the puncture operation time length weight factor to obtain a puncture operation time length score, and the results of coupling processing of the puncture center deviation score, the venous pressure score and the puncture angle deviation score are corrected with the puncture operation time length score to obtain a puncture operation evaluation value, so that the improvement of the puncture operation evaluation value acquisition accuracy is realized, and then the more accurate evaluation of the puncture operation accuracy is realized.
[0015] 4. By monitoring the change of indoor environment temperature, dynamically adjusting the low speed of the regulating valve, and by monitoring the change of the viscosity of the liquid in the dropper, dynamically extending or shortening the drop speed time, ensuring that the total amount of infusion is consistent with the pre-planned design, this dynamic environment adaptive regulation mechanism forms a closed-loop regulation of "monitoring-decision-regulation", reduces manual intervention, and thus significantly improves the accuracy, efficiency and safety of the drop speed regulation.

[0018] The embodiments of the present application provide a simulated interactive quality evaluation system and method for intravenous infusion, which solves the problem of low drop speed regulation efficiency in the process of evaluating the exhaust and puncture interaction quality of simulated intravenous infusion. The exhaust process evaluation module performs exhaust operation accuracy evaluation based on the obtained exhaust data to obtain an exhaust operation evaluation value, and then determines whether the exhaust operation is completed based on the obtained exhaust operation evaluation value. Then, the puncture process evaluation module performs puncture operation accuracy evaluation based on the obtained puncture data to obtain a puncture operation evaluation value, and then determines whether the puncture operation is completed based on the obtained puncture operation evaluation value. Finally, the drop speed regulation module performs drop speed regulation based on the obtained drop speed regulation parameters to determine whether the drop speed regulation is completed, thereby improving the drop speed regulation efficiency in the process of evaluating the exhaust and puncture interaction quality of simulated intravenous infusion.
[0019] The technical solutions in the embodiments of the present application are to solve the problem of low drop speed regulation efficiency in the process of evaluating the exhaust and puncture interaction quality of simulated intravenous infusion, and the general idea is as follows:
[0020] The exhaust operation accuracy evaluation is performed based on the obtained exhaust data, and then it is determined whether the exhaust operation is completed based on the exhaust operation accuracy degree. If yes, it is determined whether the puncture operation is completed based on the puncture operation accuracy degree. If yes, the drop speed regulation is performed based on the obtained drop speed regulation parameters, and it is determined whether the drop speed regulation is completed, thereby improving the drop speed regulation efficiency in the process of evaluating the exhaust and puncture interaction quality of simulated intravenous infusion.
[0021] In order to better understand the above technical solutions, the above technical solutions will be described in detail in combination with the drawings in the specification and specific embodiments.
[0022] As Figure 1As shown, it is a structural schematic diagram of a simulation interaction quality evaluation system for intravenous infusion provided by the embodiment of the application. The simulation interaction quality evaluation system for intravenous infusion provided by the embodiment of the application comprises an exhaust process evaluation module, a puncture process evaluation module and a drop speed adjustment module. The exhaust process evaluation module is used for exhaust operation accuracy evaluation according to the obtained exhaust data, and whether the exhaust operation is completed is determined based on the exhaust operation accuracy degree. The exhaust data are used for reflecting the exhaust state of the specified nursing student in the exhaust interaction process of the simulation intravenous infusion. The puncture process evaluation module is used for puncture operation accuracy evaluation based on the obtained puncture data if the exhaust operation is completed, and whether the puncture operation is completed is determined based on the puncture operation accuracy degree. The puncture data are used for reflecting the puncture state of the specified nursing student in the simulation puncture interaction process of the simulation intravenous infusion. The drop speed adjustment module is used for drop speed adjustment based on the obtained drop speed adjustment parameter if the puncture operation is completed, and whether the drop speed adjustment is completed is determined. The drop speed adjustment parameter is used for quantifying the drop speed adjustment efficiency of the corresponding adjustment valve of the specified nursing student after the completion of the puncture interaction of the simulation intravenous infusion.
[0023] In the embodiment, through the three evaluation modules, the exhaust, the puncture process and the drop speed adjustment are analyzed respectively. The accuracy and comprehensiveness of the simulation intravenous infusion are improved by the modular evaluation. The nursing student can repeatedly practice in the virtual environment, the clinical adaptation time is shortened, the puncture success rate is improved, the nursing student can master the intravenous infusion operation skill comprehensively, and the improvement of the drop speed adjustment efficiency in the exhaust and puncture interaction quality evaluation process of the simulation intravenous infusion is realized.
[0024] Further, the specific acquisition process of the exhaust data is as follows: under the constant temperature (18-22℃), whether the obtained drop tube inversion angle is within the drop tube inversion angle allowable range in the database is determined. If yes, the exhaust operation process of the specified nursing student in the exhaust period is monitored in real time, otherwise, the drop tube inversion angle error instruction is sent. The drop tube oxidizable content of the specified nursing student at the end of the exhaust period is obtained. When the obtained drop tube oxidizable content is less than the drop tube oxidizable content set value in the database, the exhaust data of the specified nursing student at the end of the exhaust period are obtained. The exhaust data include the needle indwelling frequency, the bubble residual amount and the exhaust operation time length. Otherwise, the exhaust operation instruction is sent again.
[0025] In the present embodiment, the drip tube inversion angle allowable range represents the range corresponding to the maximum and minimum values of the historical drip tube inversion angle of the specified nursing student at the beginning of the historical exhaust period in the database, and generally includes the case where the maximum and minimum values of the historical drip tube inversion angle are equal. The drip tube inversion angle is monitored by an inclination sensor, the drip tube oxidizable content is monitored by an optical sensor, the needle indwelling frequency is monitored by a high-precision force sensor (integrated into a medical indwelling needle puncture force tester), the bubble residual amount is monitored by an ultrasonic bubble sensor, and the exhaust operation time is obtained by a timer. The inclination sensor is usually installed on the drip tube support, and the optical sensor and the ultrasonic bubble sensor are usually installed at one-third of the distance from the bottom of the drip tube, so that the position of the liquid flow and the oxidizable content in the drip tube can be directly observed. The specific installation positions of the inclination sensor, the optical sensor and the ultrasonic bubble sensor are set by the pre-set personnel according to the actual exhaust scene.
[0026] It should be noted that, according to the requirements of drug stability and infusion safety, the drip tube oxidizable content set value should generally be lower than the threshold value of drug decomposition or discoloration. For example, for oxidizable drugs, the content set value may be required to be less than 0.1% to ensure drug stability and patient safety. The present example significantly improves the safety and efficiency of the venous infusion exhaust operation by precise exhaust operation, reducing bubble residue and reducing the risk of air embolism.
[0027] Further, the exhaust operation accuracy is evaluated according to the obtained exhaust data, and the specific process is as follows: when the obtained drip tube inversion angle is within the drip tube inversion angle allowable range in the database and the obtained drip tube oxidizable content is less than the drip tube oxidizable content set value in the database: the proportion of the obtained exhaust operation time in the total exhaust period time is corrected by the exhaust operation time weight factor to obtain an exhaust operation time score; the needle indwelling frequency score and the bubble residual amount score are coupled and processed, and the result is corrected with the exhaust operation time score to obtain an exhaust operation evaluation value; the needle indwelling frequency score represents the result of correcting the proportion of the obtained needle indwelling frequency in the maximum allowed needle indwelling frequency in the database by the needle indwelling frequency weight factor; the bubble residual amount score represents the result of correcting the proportion of the obtained bubble residual amount in the maximum allowed bubble residual amount in the database by the bubble residual amount weight factor; and the exhaust operation evaluation value is used to represent the influence degree quantization data of the exhaust data on the exhaust operation accuracy in the exhaust period.
[0028] Wherein, the specific limit expression of the exhaust operation evaluation value is:
[0029] QP=(JK1+JK2)×JK3,θ∈Δθand H<H0;
[0030] In the formula, QP represents the exhaust operation evaluation value of the specified nurse at the end of the exhaust period, JK1 represents the needle indwelling frequency score of the specified nurse at the end of the exhaust period, JK2 represents the bubble residual amount score of the specified nurse at the end of the exhaust period, JK3 represents the exhaust operation duration score of the specified nurse at the end of the exhaust period, θ represents the dropper inversion angle of the specified nurse at the beginning of the exhaust period, Δθ represents the dropper inversion angle allowable range, H represents the dropper easy oxidant content of the specified nurse at the end of the exhaust period, and H0 represents the dropper easy oxidant content set value.
[0031] The specific limit expression of the needle indwelling frequency score JK1 is: In the formula, f1 represents the needle indwelling frequency weight factor, Z1 represents the needle indwelling frequency of the specified nurse at the end of the exhaust period, and Z1 max represents the maximum allowable needle indwelling frequency.
[0032] The specific limit expression of the bubble residual amount score JK2 is: In the formula, f2 represents the bubble residual amount weight factor, Z2 represents the bubble residual amount of the specified nurse at the end of the exhaust period, and Z1 max represents the maximum allowable bubble residual amount.
[0033] The specific limit expression of the exhaust operation duration score JK3 is: In the formula, f3 represents the exhaust operation duration weight factor, Z1 represents the exhaust operation duration of the specified nurse at the end of the exhaust period, and Z30 represents the total duration of the exhaust period.
[0034] In the present embodiment, when the obtained dropper inversion angle is not within the dropper inversion angle allowable range in the database or the obtained dropper easy oxidant content is not less than the dropper easy oxidant content set value in the database, it indicates that the exhaust operation of the specified nurse does not meet the actual intravenous infusion demand, and the exhaust operation evaluation value is not calculated at this time; the bubble residual amount and the maximum allowable bubble residual amount have the same unit, both in milliliters (ml), the exhaust operation duration and the total duration of the exhaust period have the same unit, both in minutes (min); the maximum allowable needle indwelling frequency and the maximum allowable bubble residual amount respectively represent the maximum values of the historical needle indwelling frequency and the historical bubble residual amount of the specified nurse in the database at the end of the historical exhaust period.
[0035] The database stores preset weight factors closely related to the exhaust operation evaluation value, and a predefined mapping relationship is established between the weight factors and corresponding needle indwelling times weight factors, bubble residual amount weight factors, and exhaust operation time length weight factors. Notably, the mapping is not randomly set and can be one-to-one or many-to-one, for example, when the exhaust interaction accuracy of simulated intravenous infusion needs to be evaluated, the real-time acquired needle indwelling times, bubble residual amount, and exhaust operation time length can be directly input into the preset mapping relationship, so that the needle indwelling times weight factors, bubble residual amount weight factors, and exhaust operation time length weight factors matching the needle indwelling times, bubble residual amount, and exhaust operation time length can be quickly and accurately obtained.
[0036] Importantly, to ensure the consistency and comparability of the evaluation, the value ranges of the needle indwelling times weight factors, bubble residual amount weight factors, and exhaust operation time length weight factors in the example are limited to 0 to 1, and the sum of the three is 1.
[0037] The aforementioned database is a database for storing various types of setting data established before the design of the intravenous infusion simulation interaction quality evaluation system. The database contains, but is not limited to, preset exhaust operation evaluation values, preset puncture operation evaluation values, and exhaust periods and puncture periods. The various types of values are directly set by technical personnel, and the preset exhaust operation evaluation values are set according to the actual application scenarios of simulated intravenous infusion, for example, the preset exhaust operation evaluation value is represented by the result of summing and averaging the historical exhaust operation evaluation values of the designated nursing students in the database at the end of the historical exhaust period. In addition, the various types of values in the database can be set and fine-tuned by technical personnel according to actual debugging.
[0038] It should be understood that the exhaust operation evaluation value increases with the increase of the needle indwelling times, bubble residual amount, and exhaust operation time length. The increase of the needle indwelling times may lead to the increase of the bubble residual amount, as more air may be introduced by multiple needle insertions and removals. The two-step exhaust method of clinical improvement reduces the air residual rate through suspension and secondary exhaust. The increase of the bubble residual amount may prolong the exhaust operation time length, as the nurse needs to spend more time to eliminate the bubbles. The increase of the exhaust operation time length may increase the needle indwelling times, as the nurse may repeat the operation due to timeout without successful exhaust.
[0039] By considering the above mutual influence mechanism, the standardization and safety of the venous infusion exhaust operation are significantly improved. Secondly, by considering the superimposed influence of the needle indwelling times and the bubble residual amount on the exhaust operation time, the accuracy of the exhaust operation evaluation is improved, and the efficiency of the drip speed adjustment in the simulation of the exhaust and puncture interaction quality evaluation process of the venous infusion is improved, effectively solving the problem of low efficiency of drip speed adjustment in the simulation of the exhaust and puncture interaction quality evaluation process of the venous infusion in the prior art.
[0040] Further, the specific process of judging whether the exhaust operation is completed based on the exhaust operation accuracy degree is as follows: if the obtained exhaust operation evaluation value is not greater than the preset exhaust operation evaluation value in the database, it is determined that the corresponding specified nursing student completes the exhaust operation and sends a puncture operation instruction, otherwise, an exhaust speed adjustment instruction is sent; the exhaust speed adjustment instruction indicates that the exhaust speed in the drip tube is adjusted according to the obtained exhaust speed adjustment value (executed by the PID controller in the filter); the exhaust speed adjustment value indicates the result obtained by mapping the deviation of the obtained exhaust operation evaluation value in the database.
[0041] In this embodiment, the exhaust operation evaluation value deviation represents the difference between the preset exhaust operation evaluation value and the obtained exhaust operation evaluation value. Assuming that the preset exhaust operation evaluation value is 0.5 and the obtained exhaust operation evaluation value is 0.65, the exhaust operation evaluation value deviation is 0.15, and the exhaust speed adjustment value mapped in the database is -0.05. At this time, the input value of the PID (Proportional-Integral-Derivative Controller) controller is -0.05, i.e. the PID controller adjusts the exhaust speed in the drip tube to decrease by 5 units.
[0042] Through the above process and data description, it can be clearly understood how to judge whether the exhaust operation is completed based on the exhaust operation accuracy degree, and adjust the exhaust speed according to the specific situation. This adjustment method helps to ensure the accuracy and stability of the exhaust operation, and provides strong guarantee for the subsequent infusion operation.
[0043] Further, the puncture data includes puncture center deviation (distance (unit: mm) of the infusion needle / catheter tip deviating from the central axis of the blood vessel, reflecting the accuracy of the puncture position), venous pressure, puncture angle deviation and puncture operation time; the specific acquisition steps of the puncture data are: judging whether the obtained disinfection range coverage area is within the disinfection range coverage area allowed range in the database, if yes, monitoring the puncture operation process of the specified nursing student in the puncture period in real time, otherwise, issuing a disinfection area crossing reminder; obtaining the puncture center deviation of the specified nursing student at the end of the puncture period, when the obtained puncture center deviation is greater than the puncture center allowed deviation in the database, then automatically reducing the puncture center deviation data based on the obtained puncture center deviation compensation value, otherwise, obtaining the venous pressure of the specified nursing student at the end of the puncture period, the puncture center deviation compensation value represents the puncture center deviation reduction amount obtained by mapping the obtained puncture center deviation in the database, the puncture center deviation data represents the difference between the obtained puncture center deviation and the puncture center allowed deviation; when the obtained venous pressure is greater than the maximum allowed venous pressure in the database, then automatically reducing the venous pressure deviation based on the obtained venous pressure compensation value, otherwise, obtaining the puncture angle deviation and the puncture operation time of the specified nursing student at the end of the puncture period, the venous pressure compensation value represents the venous pressure reduction amount obtained by mapping the re-acquired puncture center deviation data in the database, the re-acquired puncture center deviation data represents the puncture center deviation data obtained after automatically reducing the puncture center deviation data.
[0044] In the embodiment, the puncture center deviation is monitored by a position sensor, the venous pressure is monitored by a venous pressure sensor, the puncture angle deviation is monitored by an angle sensor, and the puncture operation time is obtained by a timer, wherein the position sensor is usually installed near the puncture device so as to be able to monitor the position information of the puncture point in real time, the venous pressure sensor is usually fixed at the right atrium level position of the target object, and the angle sensor is usually installed at the connection of the puncture needle. The specific installation positions of the position sensor, the venous pressure sensor and the angle sensor are set by the pre-set personnel according to the actual puncture scene; according to the real-time monitoring results of the puncture center deviation and the venous pressure, the puncture position and the venous pressure are automatically adjusted to ensure the safety and stability of the infusion process. In addition to the puncture center deviation and the venous pressure, the puncture angle deviation and the puncture operation time are also considered in the example, which provides a basis for comprehensively evaluating the puncture operation quality, and helps the nursing students to better master the puncture skills and improve the actual operation ability in medical teaching and training.
[0045] Further, based on the obtained puncture data, the puncture operation accuracy is evaluated, and the specific process is as follows: when the obtained puncture center deviation is not greater than the puncture center allowable deviation in the database, the obtained venous pressure is not greater than the venous pressure allowable deviation in the database, and the obtained venous pressure is not greater than the maximum allowable venous pressure in the database: the proportion of the obtained puncture operation time to the total time of the puncture period is corrected by a puncture operation time weight factor to obtain a puncture operation time score; the puncture center deviation score, the venous pressure score and the puncture angle deviation score are obtained and coupled, and the result is corrected with the puncture operation time score to obtain a puncture operation evaluation value; the puncture center deviation score represents the result of correcting the proportion of the obtained puncture center deviation to the puncture center allowable deviation in the database by a puncture center deviation weight factor; the venous pressure score represents the result of correcting the proportion of the obtained venous pressure to the maximum allowable venous pressure in the database by a venous pressure weight factor; the puncture angle deviation score represents the result of correcting the proportion of the obtained puncture angle deviation to the puncture angle allowable deviation in the database by a puncture angle deviation weight factor; and the puncture operation evaluation value is used to represent the influence degree quantization data of the puncture data on the puncture operation accuracy in the puncture period.
[0046] wherein the specific limit expression of the puncture operation evaluation value is:
[0047] CP=(JL1+JL2+JL3)×JL4, M∈ΔM andΔC≤ΔC0 and Y≤Y max ;
[0048] In the formula, CP represents the puncture operation evaluation value of the specified nursing student at the end of the puncture period, JL1 represents the puncture center deviation score of the specified nursing student at the end of the puncture period, JL2 represents the venous pressure score of the specified nursing student at the end of the puncture period, JL3 represents the puncture angle deviation score of the specified nursing student at the end of the puncture period, JL4 represents the puncture operation time score of the specified nursing student at the end of the puncture period, M represents the disinfection range coverage area of the specified nursing student at the beginning of the puncture period, ΔM represents the allowable range of the disinfection range coverage area, ΔC represents the puncture center deviation of the specified nursing student at the end of the puncture period, ΔC0 represents the puncture center allowable deviation, Y represents the venous pressure of the specified nursing student at the end of the puncture period, and Y max represents the maximum allowable venous pressure.
[0049] The specific limit expression of the puncture center deviation score JL1 is: In the formula, n1 represents the puncture center deviation weight factor; the specific limit expression of the venous pressure score JL2 is: In the formula, n2 represents the venous pressure weight factor; and the specific limit expression of the puncture angle deviation score JL3 is: In the formula, n3 represents a puncture angle deviation weight factor, ΔJ represents the puncture angle deviation of the specified nurse at the end of the puncture period, and ΔJ0 represents the puncture angle allowable deviation; the specific limit expression of the puncture operation time length score JL4 is: In the formula, n4 represents a puncture operation time length weight factor, S represents the puncture operation time length of the specified nurse at the end of the puncture period, and S0 represents the total puncture period time length.
[0050] In the present embodiment, the puncture center allowable deviation, the puncture angle allowable deviation, and the maximum allowable venous pressure are set by a preset person according to the actual intravenous injection situation, the puncture center deviation and the puncture center allowable deviation have the same unit, both in millimeters (mm), the venous pressure and the maximum allowable venous pressure have the same unit, both in millimeters of mercury (mmHg), the puncture angle deviation and the puncture angle allowable deviation have the same unit, both in degrees (°), and the puncture operation time length and the total puncture period time length have the same unit, both in minutes (min).
[0051] The puncture center deviation weight factor, the venous pressure weight factor, the puncture angle deviation weight factor, and the puncture operation time length weight factor are respectively the influence degrees of the preset puncture center deviation, venous pressure, puncture angle deviation, and puncture operation time length in the database on the puncture operation process. Specifically, the preset weight factors corresponding to the puncture center deviation, venous pressure, puncture angle deviation, and puncture operation time length are stored in the database, and there is a preset mapping relationship between these weight factors and the puncture center deviation, venous pressure, puncture angle deviation, and puncture operation time length. This mapping relationship can be one-to-one or many-to-one. For example, in actual application, the real-time puncture center deviation, venous pressure, puncture angle deviation, and puncture operation time length can be input into this mapping relationship, so as to quickly obtain the corresponding weight factors.
[0052] The values of the puncture center deviation weight factor, the venous pressure weight factor, the puncture angle deviation weight factor, and the puncture operation time length weight factor in the present example generally range from 0 to 1, and the sum of the four is 1.
[0053] It should be understood that the puncture operation evaluation value increases with the increase of the puncture center deviation, venous pressure, puncture angle deviation, and puncture operation time length. When the puncture center deviation increases, the needle may not accurately enter the blood vessel, thereby increasing the pressure on the venous wall, causing the venous pressure to rise, and the rise of the venous pressure may further affect the blood flow, increasing the difficulty and risk of the puncture operation.
[0054] When the puncture angle deviation increases, it can take longer to adjust the needle position to ensure correct puncture, thereby increasing the puncture operation time; both the increase in the puncture center deviation and the puncture angle deviation can reduce the success rate of the puncture operation, thereby requiring more attempts and longer time to complete the puncture.
[0055] By considering the above mutual influence mechanism, the quality of the puncture operation can be more comprehensively evaluated, and the actual situation and difficulty of the puncture operation can be more accurately reflected. Secondly, by considering the superimposed effects of the puncture center deviation, the vein pressure and the puncture angle deviation on the puncture operation time, the accuracy of the puncture operation evaluation is improved, thereby improving the drip speed adjustment efficiency in the process of evaluating the exhaust and puncture interaction quality of the simulated intravenous infusion, effectively solving the problem of low drip speed adjustment efficiency in the process of evaluating the exhaust and puncture interaction quality of the simulated intravenous infusion in the prior art.
[0056] Further, the specific process of determining whether the puncture operation is completed based on the puncture operation accuracy degree is as follows: if the obtained puncture operation evaluation value is not greater than the preset puncture operation evaluation value in the database, it is determined that the corresponding designated nursing student completes the puncture operation, otherwise the designated nursing student is prompted to pause the puncture operation and an emergency braking instruction is triggered; the emergency braking instruction is used to automatically reset the state of the adjustment valve corresponding to the designated nursing student after completing the puncture operation to the initial state before the puncture operation of the designated nursing student according to the obtained state reset compensation value; the state reset compensation value represents the result obtained by mapping the deviation of the obtained puncture operation evaluation value in the database; the puncture operation evaluation value deviation is used to quantify the difference between the obtained puncture operation evaluation value and the preset puncture operation evaluation value.
[0057] In this embodiment, the puncture operation evaluation value deviation represents the difference between the preset puncture operation evaluation value and the obtained puncture operation evaluation value; the preset puncture operation evaluation value is represented by the result obtained by summing and averaging the historical puncture operation evaluation values of the designated nursing student at the end of the historical puncture period in the database.
[0058] This example can accurately determine whether the designated nursing student successfully completes the puncture operation by comparing the obtained puncture operation evaluation value with the preset puncture operation evaluation value, and automatically restores the initial state of the adjustment valve according to the obtained puncture operation evaluation value deviation, thereby realizing intelligent control, reducing human intervention errors, effectively improving the safety and reliability of the medical process, and providing strong support for the automation and intelligentization of the medical process.
[0059] Further, the drop speed is adjusted based on the obtained drop speed adjustment parameter, and the specific process is as follows: the drop speed adjustment parameter includes a first indoor environment temperature deviation, a first liquid viscosity deviation, a second indoor environment temperature deviation, and a second liquid viscosity deviation; P1, at the beginning of the drop speed adjustment period, the initial drop speed of the adjustment valve corresponding to the completion of the exhaust operation is obtained, and the indoor environment temperature at the current drop speed adjustment time is obtained; when the obtained indoor environment temperature is not equal to the reference indoor environment temperature in the database, P2 is executed, otherwise the change of the indoor environment temperature is continuously monitored; P2, when the obtained indoor environment temperature is greater than the reference indoor environment temperature in the database, P3 is executed, otherwise P4 is executed; P3, based on the obtained first indoor environment temperature deviation, the drop speed of the adjustment valve at the next drop speed adjustment time is increased, and based on the obtained first liquid viscosity deviation, the drop speed time of the adjustment valve at the next drop speed adjustment period is prolonged; P4, based on the obtained second indoor environment temperature deviation, the drop speed of the adjustment valve at the next drop speed adjustment time is reduced, and based on the obtained second liquid viscosity deviation, the drop speed time of the adjustment valve at the next drop speed adjustment period is shortened.
[0060] In the embodiment, the first indoor environment temperature deviation represents the difference between the obtained indoor environment temperature and the reference indoor environment temperature, and the first liquid viscosity deviation represents the difference between the liquid viscosity in the dropper at the current drop speed adjustment time and the liquid viscosity in the dropper at the last drop speed adjustment time; the second indoor environment temperature deviation represents the difference between the reference indoor environment temperature and the obtained indoor environment temperature, and the second liquid viscosity deviation represents the difference between the liquid viscosity in the dropper at the last drop speed adjustment time and the liquid viscosity in the dropper at the current drop speed adjustment time.
[0061] Specifically, the obtained first indoor environment temperature deviation is input into the drop speed PID control algorithm corresponding to the adjustment valve to obtain a drop speed increase amplitude, so as to increase the drop speed of the adjustment valve at the next drop speed adjustment time; the obtained first liquid viscosity deviation is input into the drop speed time PID control algorithm corresponding to the adjustment valve to obtain a drop speed time prolonging amplitude, so as to prolong the drop speed time of the adjustment valve at the next drop speed adjustment period; the obtained second indoor environment temperature deviation is input into the drop speed PID control algorithm corresponding to the adjustment valve to obtain a drop speed reducing amplitude, so as to reduce the drop speed of the adjustment valve at the next drop speed adjustment time; and the obtained second liquid viscosity deviation is input into the drop speed time PID control algorithm corresponding to the adjustment valve to obtain a drop speed time shortening amplitude, so as to shorten the drop speed time of the adjustment valve at the next drop speed adjustment period.
[0062] It should be noted that if the current drop speed adjustment moment is 1, the liquid viscosity in the dropper obtained at the last drop speed adjustment moment is the initial liquid viscosity of the liquid in the dropper at the beginning of the drop speed adjustment period. The present example realizes intelligent adjustment of drop speed by comprehensively considering environmental factors and liquid characteristics, significantly improves the accuracy of drop speed adjustment, nursing efficiency and patient safety, and the core advantage lies in the conversion of traditional experience-based adjustment to data-driven intelligent adjustment, which provides a scientific basis for clinical nursing.
[0063] Further, the specific process of judging whether the drop speed adjustment is completed is as follows: at the end of the drop speed adjustment period, the actual drop speed corresponding to the adjustment valve is obtained, the drop speed error value is obtained, and the reset state of the adjustment valve is monitored in real time; when the obtained drop speed error value is within the drop speed error value allowable range in the database and the adjustment valve does not automatically reset within the preset monitoring period, the drop speed adjustment is completed and a drop speed adjustment recovery instruction is sent, otherwise a humidity warning instruction is sent and a preset personnel is prompted to repair the step motor drive circuit in the adjustment valve; the drop speed adjustment recovery instruction includes a first drop speed recovery instruction and a second drop speed recovery instruction; the first drop speed recovery instruction is used to automatically recover the drop speed of the corresponding adjustment valve of the specified nurse after completing the puncture to the initial drop speed of the adjustment valve; the second drop speed recovery instruction is used to automatically recover the drop speed of the corresponding adjustment valve of the specified nurse after completing the puncture to the preset drop speed of the adjustment valve.
[0064] In the present embodiment, the first drop speed recovery: assuming that the drop speed of the corresponding adjustment valve of the specified nurse at the end of the puncture period is 50 drops per minute, i.e. the first drop speed recovery automatically recovers 50 drops per minute to the initial drop speed 60 drops per minute of the adjustment valve through the PID controller in the adjustment valve; the second drop speed recovery: assuming that the drop speed of the corresponding adjustment valve of the specified nurse at the end of the puncture period is 40 drops per minute, i.e. the second drop speed recovery automatically recovers 40 drops per minute to the preset drop speed 50 drops per minute of the adjustment valve through the PID controller in the adjustment valve.
[0065] The present example can accurately judge whether the drop speed adjustment after the puncture operation is completed by monitoring the drop speed error value and the reset state of the adjustment valve in real time, thereby ensuring the accuracy of the puncture operation. In the drop speed adjustment process, the evaluation step after the puncture operation is simplified, the efficiency and quality of medical work are improved, and through the sending of the warning instruction, the preset personnel can be guided to quickly locate and solve the problem, thereby optimizing the medical process.
