Description

Technical Field

[0001] The present invention relates to the technical field of anesthesia control systems, and in particular to an oral anesthesia control system based on dynamic pressure detection. Background Art

[0002] Oral anesthesia refers to the local injection of anesthetic drugs in the mouth, temporarily blocking the sensory conduction of nerve endings and fibers in a certain area of ​​the body. It is commonly used in oral treatment to relieve the patient's pain. Traditional oral anesthesia methods are mostly manual injections by medical staff using disposable syringes or mechanical injection pumps to push the syringes for injection. During the manual injection process, the injection progress is entirely controlled by the medical staff's experience. It is necessary to avoid operational errors that affect the anesthesia effect and cause pain to the patient. The medical staff's operational experience is required to be high. During the mechanical injection process, it is not convenient to adjust the injection flow rate of the anesthetic drug in real time according to the injection progress, which affects the injection effect. In order to reduce errors during the anesthesia operation, we propose an oral anesthesia control system based on dynamic pressure detection. Summary of the Invention

[0003] The purpose of the present invention is to provide an oral anesthesia control system based on dynamic pressure detection to solve the problems raised by the above background technology.

[0004] The object of the present invention can be achieved by the following technical solutions: an oral anesthesia control system based on dynamic pressure detection, comprising a database, an early warning module and a control module, and also comprising an injection point positioning module, an injection flow rate acquisition module and an injection progress monitoring unit;

[0005] The injection point positioning module is used to identify and scan the inside of the patient's oral cavity according to the specific situation of the patient's oral treatment surgery, and find the corresponding anesthetic injection point for positioning;

[0006] An injection flow rate acquisition module is used to select an appropriate type of anesthetic drug according to the patient's specific condition and the required anesthetic state, and obtain the total injection dose parameter of the anesthetic drug, homogenize the total injection dose parameter of the anesthetic drug, obtain a number of uniform injection flow rate data of the anesthetic drug, screen the multiple uniform injection flow rate data, match them with the reference injection flow rate data of the corresponding type of anesthetic drug, select the uniform injection flow rate data that successfully matches to set the injection flow rate, and if the match fails, substitute the reference injection flow rate data into the multiple uniform injection flow rate data for ascending order sorting, select the uniform injection flow rate data sorted one place above the reference injection flow rate data to set the injection flow rate, and transmit it to the injection progress monitoring unit;

[0007] An injection progress monitoring unit is used to continuously calculate the dynamic pressure during the injection process based on the received injection flow rate data, and to monitor the injection flow rate data in real time. If the injection flow rate shows an accelerating trend, the dynamic pressure calculated based on the real-time injection flow rate data is adjusted to decrease, and a corresponding driving force reduction control instruction is generated. If the injection flow rate shows a slowing trend, the dynamic pressure calculated based on the real-time injection flow rate data is adjusted to increase, and a corresponding driving force increase control instruction is generated and transmitted to the control module.

[0008] The control module makes targeted adjustments to the driving force of the syringe according to the received control instructions, controls the dynamic pressure in the syringe by adjusting the driving force, and completes the control and adjustment of the anesthetic drug injection progress.

[0009] As a further improvement of the present invention: positioning is performed based on finding the corresponding anesthetic injection point, specifically:

[0010] Set several screening keywords and match the patient's oral treatment type with the screening keywords. If the match is successful, the corresponding reference anesthetic injection point location data is obtained. The patient's oral cavity is scanned by an intelligent image scanning device, and the location that matches the reference anesthetic injection point location is selected as the injection point. If the match fails, the medical staff inputs the location of the anesthetic injection point.

[0011] For example, set several filtering keywords such as tooth extraction, dental implant, orthopedics, etc., and match the patient's oral treatment type with the filtering keywords. If the patient's oral treatment type is tooth extraction, it can be matched with the filtering keyword "tooth extraction" to obtain the corresponding data on the injection points of several anesthetic drugs for oral extraction;

[0012] The patient's oral cavity is scanned by an intelligent image scanning device to obtain the location of the tooth extraction treatment, and the location of the tooth extraction treatment is matched with the corresponding data of several anesthetic injection points. If the match is successful, the corresponding injection point is obtained. If the match fails, the medical staff inputs the location of the anesthetic injection point.

[0013] As a further improvement of the present invention: based on the injection flow rate acquisition module, the specific analysis is as follows:

[0014] Set several screening keywords and match the anesthesia status required for the patient's oral treatment with the screening keywords. If the match is successful, the corresponding anesthetic drug and the required total injection dose parameters are obtained and homogenized to obtain several uniform injection flow rate data. If the match fails, the medical staff inputs the anesthetic drug used and the required total injection dose;

[0015] For example, set several screening keywords such as local anesthesia, partial anesthesia, general anesthesia, etc., and match the anesthesia status required for the patient's oral treatment with the screening keywords. If the anesthesia status required for the patient's oral treatment is local anesthesia, it can be matched with the screening keyword local anesthesia to obtain the corresponding local anesthesia anesthetic type and the required total injection dose parameters. If the match fails, the medical staff will input the anesthetic drug used and the required total injection dose;

[0016] Substitute the total injection dose parameters into the formula The uniform injection flow rate data YS is obtained, ZCS is expressed as the total dose parameter, and PC is expressed as the set total injection time (minutes);

[0017] Reference injection flow rate data is set according to the patient's required anesthesia state and anesthetic drugs, and a number of uniform injection flow rate data are matched with the reference injection flow rate data. If the match is successful, the matched uniform injection flow rate data is set as the injection flow rate. If the match fails, the reference injection flow rate data is substituted into the number of uniform injection flow rate data for ascending order sorting, and the uniform injection flow rate data sorted one place above the reference injection flow rate data is selected as the injection flow rate;

[0018] Substitute the total injection dose parameters into the formula Obtain the reference injection flow rate data CK, substitute the uniform injection flow rate data and the reference injection flow rate data into the comparison formula. If YS = CK, the match is successful, and the uniform injection flow rate data with YS = CK is set as the injection flow rate. If YS ≠ CK, the match fails, and CK is substituted into YS for ascending order sorting, such as YS①, YS②, CK, YS③, then select YS② as the injection flow rate;

[0019] Based on the uniform injection flow rate, the corresponding uniform injection time is obtained, and the uniform injection flow rate is limited by the uniform injection time. If the uniform injection flow rate exceeds the injection dose of the uniform injection time, or does not reach the injection dose of the uniform injection time, it is determined that the injection flow rate has changed, and the corresponding injection flow rate speed-up or speed-down instruction is generated. The uniform injection flow rate is adjusted according to the corresponding instruction; the total dose parameter is substituted into the formula Obtain the uniform injection time data YC, set the reference uniform injection time corresponding to the uniform injection flow rate and substitute it into the formula ZC=YC×YS to obtain the reference injection dose ZC of the uniform injection time corresponding to the uniform injection flow rate, and set the actual injection dose of the uniform injection time corresponding to the uniform injection flow rate as ZC'. If ZC>ZC' or ZC<ZC', there is a phenomenon that the uniform injection time corresponding to the uniform injection flow rate does not reach the required injection dose or exceeds the required injection dose. Determine the change in the injection flow rate based on the calculation results and generate the corresponding adjustment instructions.

[0020] As a further improvement of the present invention: based on the injection progress supervision unit, the specific analysis is as follows:

[0021] The initial dynamic pressure data in the syringe is calculated by the obtained injection flow rate data, and the dynamic pressure data of each injection stage is predicted as a reference fluctuation diagram. At the same time, the injection flow rate data is monitored in real time, and the real-time dynamic pressure data in the syringe is calculated, and the real-time dynamic pressure data is compared with the reference fluctuation diagram. If the real-time dynamic pressure data is significantly larger than the reference fluctuation diagram data, it is determined that the injection flow rate has changed and is showing an accelerating trend. There is a phenomenon that the uniform injection flow rate exceeds the required injection dose for the uniform injection time. A corresponding injection flow rate acceleration instruction is generated. According to the injection flow rate acceleration instruction, a driving force reduction control instruction is generated to control the driving force received by the syringe to be reduced, thereby reducing the real-time dynamic pressure in the syringe and slowing down the injection flow rate. If the real-time dynamic pressure data is significantly smaller than the reference fluctuation diagram data, it is determined that the injection flow rate has changed and is showing a slowing trend. There is a phenomenon that the uniform injection flow rate does not reach the required injection dose relative to the uniform injection time. A corresponding injection flow rate slowdown instruction is generated. According to the injection flow rate slowdown instruction, a driving force increase control instruction is generated to control the driving force received by the syringe to be increased, thereby increasing the real-time dynamic pressure in the syringe and speeding up the injection flow rate.

[0022] Let the density of the anesthetic drug be p and substitute into the formula Obtain initial dynamic pressure data P;

[0023] Set the real-time injection flow rate data as YS' and substitute it into the formula Get real-time dynamic pressure data P1';

[0024] The total injection dose parameter ZCS1 remaining after the first stage of uniform injection of anesthetic drugs is obtained by the formula ZCS1 = ZCS-YS, and the total injection time parameter PC1 remaining after the first stage of uniform injection of anesthetic drugs is obtained by the formula PC1 = PC-YC. Substitute it into the formula Obtain the uniform injection flow rate YS1 of the remaining drug after the uniform injection of the first stage anesthetic drug, and substitute it into the formula The first-stage dynamic pressure data P1 in the syringe after the first-stage anesthetic drug injection is obtained, and the dynamic pressure data P2, P3, etc. of the second, third, and final stages of the anesthetic drug injection are calculated in the same manner. The dynamic pressure data of each stage are arranged in a graph to serve as a dynamic pressure reference fluctuation line;

[0025] Match the real-time dynamic pressure data P1' with the dynamic pressure fluctuation line. If the match is successful, it indicates that the anesthetic drug is in a uniform injection flow rate state. If the real-time dynamic pressure data P1' is significantly larger than the dynamic pressure fluctuation line, it indicates that the real-time dynamic pressure P1' is too large and needs to be reduced and adjusted. If the real-time dynamic pressure data P1' is significantly smaller than the dynamic pressure fluctuation line, it indicates that the real-time dynamic pressure P1' is too small and needs to be increased and adjusted.

[0026] As a further improvement of the present invention: Based on the control module, the specific analysis is as follows:

[0027] The driving force applied to the syringe is adjusted by receiving the driving force control instruction. When the driving force changes, the dynamic pressure in the syringe is adjusted, and the injection flow rate of the anesthetic drug is controlled by utilizing the change in dynamic pressure.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention monitors the flow rate changes during the injection of anesthetic drugs in the syringe, calculates the dynamic pressure in the syringe, and controls the dynamic pressure to make corresponding adjustments according to the flow rate changes, thereby achieving control of the injection flow rate of the anesthetic drugs, which is beneficial to controlling the stability of the injection flow rate of the anesthetic drugs, thereby reducing the operating burden of medical staff and reducing operational errors; the present invention can automatically adjust and control the injection flow rate of the anesthetic drugs in the syringe according to the changes in the injection flow rate of the anesthetic drugs, thereby maintaining the stability of the injection flow rate, which is beneficial to avoiding the phenomenon of pain in the patient caused by injection flow rate fluctuations, reducing the probability of operational errors, and at the same time, the stable injection flow rate is beneficial to improving the use effect of the anesthetic drugs.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 As shown, the oral anesthesia control system based on dynamic pressure detection includes a database, an early warning module, a control module, an injection point positioning module, an injection flow rate acquisition module and an injection progress monitoring unit;

[0035] The database is used to store the injection point data corresponding to oral treatment, as well as the corresponding anesthetic drug type and injection dosage data information;

[0036] Specifically including: oral orthodontic treatment, dental treatment..., injection points include maxillary anterior teeth, maxillary posterior teeth..., ester local anesthetics: the representative drug is procaine, which has low toxicity, takes effect 1-3 minutes after injection, can last for 30-45 minutes, and the maximum dose can reach 1000mg at a time; amide local anesthetics: including lidocaine, bupivacaine, and ropivacaine; 0.5%-1% concentration of lidocaine is commonly used in clinical practice for local anesthesia, with rapid onset and a duration of action of 60-90 minutes, and the maximum dose can reach 400mg at a time...

[0037] The injection point positioning module is used to identify and scan the inside of the patient's oral cavity according to the specific situation of the patient's oral treatment surgery, and find the corresponding anesthetic injection point for positioning; specifically:

[0038] Set several screening keywords and match the patient's oral treatment type with the screening keywords. If the match is successful, the corresponding reference anesthetic injection point location data is obtained. The patient's oral cavity is scanned by an intelligent image scanning device, and the location that matches the reference anesthetic injection point location is selected as the injection point. If the match fails, the medical staff inputs the location of the anesthetic injection point.

[0039] For example, set several filtering keywords such as tooth extraction, dental implant, orthopedics, etc., and match the patient's oral treatment type with the filtering keywords. If the patient's oral treatment type is tooth extraction, it can be matched with the filtering keyword "tooth extraction" to obtain the corresponding data on the injection points of several anesthetic drugs for oral extraction;

[0040] The patient's oral cavity is scanned by an intelligent image scanning device to obtain the location of the tooth extraction treatment, and the location of the tooth extraction treatment is matched with the corresponding data of several anesthetic injection points. If the match is successful, the corresponding injection point is obtained. If the match fails, the medical staff inputs the location of the anesthetic injection point.

[0041] The injection flow rate acquisition module is used to select the appropriate type of anesthetic drug according to the patient's specific condition and the required anesthetic state, and obtain the total injection dose parameter of the anesthetic drug, homogenize the total injection dose parameter of the anesthetic drug, obtain a number of uniform injection flow rate data of the anesthetic drug, screen the several uniform injection flow rate data, match them with the reference injection flow rate data of the corresponding type of anesthetic drug, select the uniform injection flow rate data that successfully matches to set the injection flow rate, if the match fails, substitute the reference injection flow rate data into the several uniform injection flow rate data for ascending order sorting, select the uniform injection flow rate data sorted one place above the reference injection flow rate data to set the injection flow rate, and transmit it to the injection progress monitoring unit. The specific analysis is as follows:

[0042] Set several screening keywords and match the anesthesia status required for the patient's oral treatment with the screening keywords. If the match is successful, the corresponding anesthetic drug and the required total injection dose parameters are obtained and homogenized to obtain several uniform injection flow rate data. If the match fails, the medical staff inputs the anesthetic drug used and the required total injection dose;

[0043] For example, set several screening keywords such as local anesthesia, partial anesthesia, general anesthesia, etc., and match the anesthesia status required for the patient's oral treatment with the screening keywords. If the anesthesia status required for the patient's oral treatment is local anesthesia, it can be matched with the screening keyword local anesthesia to obtain the corresponding local anesthesia anesthetic type and the required total injection dose parameters. If the match fails, the medical staff will input the anesthetic drug used and the required total injection dose;

[0044] Substitute the total injection dose parameters into the formula The uniform injection flow rate data YS is obtained, ZCS is expressed as the total dose parameter, and PC is expressed as the set total injection time (minutes);

[0045] Reference injection flow rate data is set according to the patient's required anesthesia state and anesthetic drugs, and a number of uniform injection flow rate data are matched with the reference injection flow rate data. If the match is successful, the matched uniform injection flow rate data is set as the injection flow rate. If the match fails, the reference injection flow rate data is substituted into the number of uniform injection flow rate data for ascending order sorting, and the uniform injection flow rate data sorted one place above the reference injection flow rate data is selected as the injection flow rate;

[0046] Substitute the total injection dose parameters into the formula Obtain the reference injection flow rate data CK, substitute the uniform injection flow rate data and the reference injection flow rate data into the comparison formula. If YS = CK, the match is successful, and the uniform injection flow rate data with YS = CK is set as the injection flow rate. If YS ≠ CK, the match fails, and CK is substituted into YS for ascending order sorting, such as YS①, YS②, CK, YS③, then select YS② as the injection flow rate;

[0047] Since the set reference injection flow rate data is mostly the optimal injection flow rate within the patient's tolerance range, if it exceeds the reference injection flow rate data range, it is easy to cause pain to the patient. Therefore, if the match is not successful, the uniform injection flow rate within the reference injection flow rate data range and closest to the reference injection flow rate data is selected as the injection flow rate;

[0048] Based on the uniform injection flow rate, the corresponding uniform injection time is obtained, and the uniform injection flow rate is limited by the uniform injection time. If the uniform injection flow rate exceeds the injection dose required for the uniform injection time, or does not reach the injection dose required for the uniform injection time, it is determined that the injection flow rate has changed, and a corresponding injection flow rate speed-up or speed-down instruction is generated. The uniform injection flow rate is controlled and adjusted according to the corresponding instruction;

[0049] Substituting the total dose parameters into the formula Obtain the uniform injection time data YC, set the reference uniform injection time corresponding to the uniform injection flow rate and substitute it into the formula ZC=YC×YS to obtain the reference injection dose ZC of the uniform injection time corresponding to the uniform injection flow rate, and set the actual injection dose of the uniform injection time corresponding to the uniform injection flow rate as ZC'. If ZC>ZC' or ZC<ZC', there is a phenomenon that the uniform injection time corresponding to the uniform injection flow rate does not reach the required injection dose or exceeds the required injection dose. Determine the change in the injection flow rate based on the calculation results and generate the corresponding adjustment instructions.

[0050] The injection progress monitoring unit is used to continuously calculate the dynamic pressure during the injection process based on the received injection flow rate data, and at the same time monitor the injection flow rate data in real time. If the injection flow rate shows an accelerating trend, the dynamic pressure calculated based on the real-time injection flow rate data is adjusted to decrease, and a corresponding driving force reduction control instruction is generated. If the injection flow rate shows a slowing trend, the dynamic pressure calculated based on the real-time injection flow rate data is adjusted to increase, and a corresponding driving force increase control instruction is generated and transmitted to the control module. Specifically:

[0051] The initial dynamic pressure data in the syringe is calculated by the obtained injection flow rate data, and the dynamic pressure data of each injection stage is predicted as a reference fluctuation diagram. At the same time, the injection flow rate data is monitored in real time, and the real-time dynamic pressure data in the syringe is calculated, and the real-time dynamic pressure data is compared with the reference fluctuation diagram. If the real-time dynamic pressure data is significantly larger than the reference fluctuation diagram data, it is determined that the injection flow rate has changed and is showing an accelerating trend. There is a phenomenon that the uniform injection flow rate exceeds the required injection dose for the uniform injection time. A corresponding injection flow rate acceleration instruction is generated. According to the injection flow rate acceleration instruction, a driving force reduction control instruction is generated to control the driving force received by the syringe to be reduced, thereby reducing the real-time dynamic pressure in the syringe and slowing down the injection flow rate. If the real-time dynamic pressure data is significantly smaller than the reference fluctuation diagram data, it is determined that the injection flow rate has changed and is showing a slowing trend. There is a phenomenon that the uniform injection flow rate does not reach the required injection dose relative to the uniform injection time. A corresponding injection flow rate slowdown instruction is generated. According to the injection flow rate slowdown instruction, a driving force increase control instruction is generated to control the driving force received by the syringe to be increased, thereby increasing the real-time dynamic pressure in the syringe and speeding up the injection flow rate.

[0052] Let the density of the anesthetic drug be p and substitute into the formula Obtain initial dynamic pressure data P;

[0053] Set the real-time injection flow rate data as YS' and substitute it into the formula Get real-time dynamic pressure data P1';

[0054] As attached Figure 2As shown, the total injection dose parameter ZCS1 remaining after the first stage of uniform injection of anesthetic drugs is obtained by the formula ZCS1 = ZCS-YS, and the total injection time parameter PC1 remaining after the first stage of uniform injection of anesthetic drugs is obtained by the formula PC1 = PC-YC. Substitute it into the formula Obtain the uniform injection flow rate YS1 of the remaining drug after the uniform injection of the first stage anesthetic drug, and substitute it into the formula The first-stage dynamic pressure data P1 in the syringe after the first-stage anesthetic drug injection is obtained, and the dynamic pressure data P2, P3, etc. of the second, third, and final stages of the anesthetic drug injection are calculated in the same manner. The dynamic pressure data of each stage are arranged in a graph to serve as a dynamic pressure reference fluctuation line;

[0055] Match the real-time dynamic pressure data P1' with the dynamic pressure fluctuation line. If the match is successful, it indicates that the anesthetic drug is in a uniform injection flow rate state. If the real-time dynamic pressure data P1' is significantly larger than the dynamic pressure fluctuation line, it indicates that the real-time dynamic pressure P1' is too large and needs to be reduced and adjusted. If the real-time dynamic pressure data P1' is significantly smaller than the dynamic pressure fluctuation line, it indicates that the real-time dynamic pressure P1' is too small and needs to be increased and adjusted.

[0056] The control module makes targeted adjustments to the pushing force applied to the syringe according to the control instructions received, and controls the dynamic pressure applied to the syringe by adjusting the pushing force, thereby completing the control and adjustment of the injection progress of the anesthetic drug. Specifically, since the dynamic pressure in the syringe is formed by applying a thrust to the push rod of the syringe, when controlling and adjusting the dynamic pressure in the syringe, it is necessary to adjust the pushing force applied to the syringe. By adjusting the pushing force control instructions received, the pushing force applied to the syringe is adjusted. When the pushing force changes, the dynamic pressure in the syringe is adjusted, and the injection flow rate of the anesthetic drug is controlled by utilizing the change in dynamic pressure.

[0057] The early warning module issues an early warning prompt when the injection flow rate and dynamic pressure of the anesthetic drug change and do not match the predetermined results. Example 2: Based on Example 1, the early warning module is also used to conduct a counseling analysis on the patient. The specific analysis process is: obtaining the patient's age, medical records, body temperature data, blood pressure data and heart rate;

[0058] The temperature data and blood pressure data are parsed to obtain the corresponding temperature values ​​and blood pressure values ​​as well as the corresponding collection time; the temperature values ​​are sorted according to the order of collection time, and the sizes of the two adjacent temperature values ​​are compared. If the temperature value in the front order is smaller than the temperature value in the back order, the difference between the two adjacent temperature values ​​is calculated to obtain the temperature difference, and all the temperature differences are summed up to obtain the total temperature value; the average value and variance corresponding to all temperature values ​​are calculated to obtain the average temperature value and the temperature variance value; the total temperature value, the average temperature value and the temperature variance value are normalized and the values ​​of the three are taken, marked as TZi, TPi and TSi respectively, where i is the patient number; and substituted into the temperature analysis model. Obtain the body temperature variance TQi; μ1, μ2, and μ3 are weight factors corresponding to the total temperature rise, average temperature, and temperature variance, respectively, and their sizes are user-defined, such as 0.35, 0.26, and 0.4, respectively; TYi is the average body temperature of the patient at this moment ten days before the current moment. For example, if the current moment is ten o'clock, obtain the body temperature at ten o'clock ten days before the current moment and take the average value to obtain TYi. The blood pressure data is analyzed to obtain the patient's average blood pressure value of the previous five days and several blood pressure values ​​within three hours before the current moment. The several blood pressure values ​​are averaged to obtain the average blood pressure value. If the average blood pressure value is greater than the patient's average blood pressure value of the previous five days, the largest blood pressure value among the several blood pressure values ​​is obtained and marked as the maximum blood pressure value. The values ​​of the average blood pressure value and the maximum blood pressure value are converted into straight line lengths according to a certain ratio. A circle is constructed with the straight line length of the average blood pressure value as the radius. The center of the circle is selected as the starting point to make a height equal to the straight line length corresponding to the maximum blood pressure value. A cone is constructed with the circle and the height. The volume of the cone is extracted and the volume value is marked as the blood pressure base value and marked as XYi; the patient's current heart rate is marked as XLi; the body anomaly value, blood pressure base value and heart rate are substituted into the initial guidance classification model SDci=TQi×η1+XYi×η2+XLi×η3 to obtain the initial guidance value SDci, where η1, η2, and η3 are the weight coefficients corresponding to the body anomaly value, blood pressure base value and heart rate, respectively, and the values ​​are 0.4, 0.3, and 0.3, respectively.

[0059] Set initial dredging threshold 1 and initial dredging threshold 2, initial dredging threshold 2 is greater than initial dredging threshold 1, compare the initial dredging value with initial dredging threshold 1 and initial dredging threshold 2, if initial dredging threshold 1 < initial dredging value ≤ initial dredging threshold 2, then generate content display instructions and send them to the corresponding display terminal, and the display terminal displays the content of the oral anesthesia process, including the anesthesia process, the effect of anesthetics, and possible risks and countermeasures, so that the patient can have a full understanding and confidence in his or her own surgical process; if initial dredging threshold 2 < initial dredging value, then parse the medical records to obtain the medical treatment time and the total number of medical treatments, sort the medical treatment times according to chronological order, calculate the difference between two adjacent medical treatment times to obtain the medical treatment interval length, calculate the average of all medical treatment interval length values ​​to obtain the average interval value, and divide the total number of medical treatments by the average interval value to obtain the medical treatment value; normalize the age, initial dredging value and medical treatment value, and take the normalized values ​​of the three and substitute them into the dredging model Output the patient's drainage value SDzi, where NLi is the value of the patient's age, JPi is the value of the patient's medical treatment value, η4, η5, and η6 are the weight coefficients corresponding to the initial drainage value, age, and medical treatment value, respectively, with values ​​of 0.55, 0.15, and 0.3;

[0060] When the counseling value is within the range of interval one, the corresponding playback device is controlled to play music; when the counseling value is within the range of interval two, the medical staff's smart terminal sends a counseling instruction. After receiving the counseling instruction through the smart terminal, the medical staff implements the counseling strategy for the patient. The counseling strategy includes positive language and attitude, giving the patient positive psychological hints, such as emphasizing the safety and effectiveness of anesthesia, and the controllability of the surgical process; as well as encouraging the patient and telling some light topics, or sharing some successful surgical cases to relieve the patient's tension.

The oral anesthesia control system based on dynamic pressure detection according to claim 1, characterized in that: The specific process of the injection progress monitoring unit to monitor the injection flow rate in real time is as follows: The initial dynamic pressure data in the syringe is calculated by using the obtained injection flow rate data, and the dynamic pressure data in each injection stage is predicted as a reference fluctuation diagram. At the same time, the injection flow rate data is monitored in real time, and the real-time dynamic pressure data in the syringe is calculated. The real-time dynamic pressure data is compared with the reference fluctuation diagram. If the real-time dynamic pressure data is significantly greater than the reference fluctuation diagram data, it is determined that the injection flow rate has changed and is showing an accelerating trend. A corresponding injection flow rate acceleration instruction is generated. According to the injection flow rate acceleration instruction, a driving force reduction control instruction is generated to control the driving force on the syringe to be reduced, thereby reducing the real-time dynamic pressure in the syringe and slowing down the injection flow rate. If the real-time dynamic pressure data is significantly smaller than the reference fluctuation chart data, it is determined that the injection flow rate has changed and is showing a slowing trend, and a corresponding injection flow rate slowing instruction is generated. Based on the injection flow rate slowing instruction, a driving force increase control instruction is generated to control the increase in the driving force on the syringe, thereby increasing the real-time dynamic pressure in the syringe and speeding up the injection flow rate.

5. The oral anesthesia control system based on dynamic pressure detection according to claim 1, characterized in that: It also includes an early warning module, which is used to issue an early warning prompt when the injection flow rate or dynamic pressure of the anesthetic drug changes and does not match the predetermined result.
