[0055] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0056] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0057] The main solution of the embodiment of the present application is: determine the drug infusion level corresponding to the drug to be infused according to the pain level of the user to be treated; determine the drug infusion volume range corresponding to the drug to be infused based on the drug infusion level; determine the user's arterial systolic blood pressure according to the diagnostic information of the user to be treated, and determine the analgesic pump output pressure according to the user's arterial systolic blood pressure; generate a drug infusion strategy based on the drug infusion volume range and the analgesic pump output pressure; and deliver the drug to be infused from the first drug storage device to the hepatic artery of the user to be treated according to the drug infusion strategy.

[0058] In this embodiment, for the sake of ease of description, the following description will be made using the analgesic pump as the executing entity.

[0059] The present application provides a solution that can generate a drug infusion strategy based on the drug infusion volume corresponding to the drug to be infused and the output pressure of the analgesic pump, and deliver the drug to be infused to the hepatic artery of the user to be treated through the drug infusion strategy, thereby solving the technical problem in the prior art that the drug administration control of the analgesic pump using a single and fixed control method often cannot meet the treatment needs and has poor safety.

[0060] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a control device for an arterial analgesia pump pumping lidocaine, etc. The following takes the control device for an arterial analgesia pump pumping lidocaine as an example (hereinafter referred to as the device) to illustrate this embodiment and the following embodiments.

[0061] Based on this, the embodiment of the present application provides a control method for an arterial analgesia pump that pumps lidocaine, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the control method of the arterial analgesia pump for pumping lidocaine in the present application.

[0062] In this embodiment, the control method of the arterial analgesia pump pumping lidocaine is applied to the analgesia pump, and the infusion tube of the analgesia pump is respectively connected to the first drug storage device and the microcatheter placed in the hepatic artery during interventional surgery, including steps S10 to S50:

[0063] Step S10: determining a drug infusion level corresponding to the drug to be infused according to the pain level of the user to be treated.

[0064] In this embodiment, the drug to be infused may be lidocaine. Figure 2 , Figure 2 This is a schematic diagram of the structure of the analgesic pump in the control method of the arterial analgesic pump for pumping lidocaine in this application. Figure 2 As shown, in this embodiment, the infusion tube 1 of the analgesic pump is respectively connected to the first drug storage device 2 and the microcatheter placed in the hepatic artery of the user to be treated during interventional surgery.

[0065] Furthermore, if Figure 2As shown, in this solution, a second drug storage device 3 is also provided, in which chemotherapy drugs are stored, and the second drug storage device 3 is connected to the infusion tube 1 of the analgesic pump, and a Y-valve 4 is provided in the infusion tube 1, and one end of the Y-valve 4 is connected to the first drug storage device 2, and the other end is connected to the second drug storage device 3. In addition, in this embodiment, the first drug storage device 2 and the second drug storage device 3 of the analgesic pump are respectively provided with a first pump body 5 and a second pump body 6, and the first pump body 5 and the second pump body 6 are used to control the drug from the corresponding drug storage device to be input into the hepatic artery of the user to be treated.

[0066] It should be understood that the first drug storage device may be a container device for storing drugs to be infused, wherein the drugs to be infused may be drugs with analgesic effects. In the present embodiment, the drugs to be infused may be lidocaine solution.

[0067] It should be noted that the above-mentioned pain level can be an indicator for characterizing the user's pain level. In this embodiment, the greater the user's pain level, the higher the corresponding pain level; correspondingly, the smaller the user's pain level, the lower the corresponding pain level. In this embodiment, the user's pain level can be determined by collecting the potential change amplitude data of the electromyographic signal within a preset range near the user's surgical site, that is, the user's current pain level can be determined based on the collected potential change amplitude data of the electromyographic signal.

[0068] It should be noted that the above-mentioned drug infusion level can be an indicator used in the analgesic pump to characterize the dosage of the analgesic drug infused into the user's hepatic artery. For example, in this embodiment, five drug infusion levels can be set, namely level 1, level 2, level 3, level 4 and level 5, and this embodiment does not limit this. In practical applications, several drug infusion levels can be set in the analgesic pump according to the different pain levels of the user. Generally speaking, the higher the user's pain level, the higher the corresponding drug infusion level in the analgesic pump. Correspondingly, more analgesic drugs need to be infused into the user for pain relief.

[0069] Step S20: determining a drug infusion volume range corresponding to the drug to be infused based on the drug infusion level.

[0070] It should be understood that the above-mentioned drug infusion volume range can be the range corresponding to the infusion measurement when the analgesic pump performs drug infusion, wherein the drug infusion volume in this embodiment can include the continuous infusion volume generated by the analgesic pump at a continuous infusion rate and the single drug infusion volume controlled by the user.

[0071] Furthermore, the method also includes: when detecting a pain relief request triggered by the user to be treated, updating the drug infusion range according to increasing the infusion volume of the target drug; and returning to the step of generating a drug infusion strategy based on the drug infusion range and the analgesia pump output pressure.

[0072] It should be noted that the above-mentioned target drug increase infusion volume can be the amount of liquid medicine that the analgesic pump will increase after the user presses the self-controlled drug administration button. For example, in this embodiment, the target drug increase infusion volume can be set to 0.5ml. In actual applications, when using the analgesic pump to relieve pain for the user, if the user feels that the pain relief effect is not good or the pain is aggravated, the user can press the self-controlled drug administration button in the analgesic pump to trigger the above-mentioned pain relief request. After the analgesic pump detects the pain relief request triggered by the user, the infusion volume of the liquid medicine currently infused to the user can be increased by 0.5ml. Specifically, the drug infusion volume in the drug infusion volume range can be increased by 0.5ml to obtain the drug infusion volume range after the infusion volume is increased, so that the drug infusion strategy generated based on the drug infusion volume range after the infusion volume is increased can be used to infuse drugs to the user according to the drug infusion strategy.

[0073] Step S30: Determine the user's arterial systolic pressure according to the diagnosis information of the user to be treated, and determine the analgesia pump output pressure according to the user's arterial systolic pressure.

[0074] It should be understood that the above-mentioned diagnostic information may be diagnostic information obtained after the user to be treated is examined in the hospital, which may include basic information of the user to be treated (such as the user's name, gender, age, etc.), medical examination information (such as the user's medical history, cause of disease, medical diagnosis results, etc.), etc. This embodiment does not limit this.

[0075] It should be noted that the above-mentioned user's arterial systolic pressure can be the systolic pressure at the hepatic artery of the user to be treated. The above-mentioned analgesic pump output pressure is the output pressure of the pump action in the analgesic pump. In practical applications, the normal value of arterial systolic pressure is usually 90mmHg-140mmHg. In this embodiment, the arterial systolic pressure of the user to be treated can be determined based on the medical examination information of the user to be treated. For example, the user to be treated is a hypertensive patient, and his arterial systolic pressure is 160mmHg. Since the pressure of the existing analgesic pump is usually very small and is only suitable for conventional analgesia, and the analgesic pump in this scheme is to be connected to the user's hepatic artery to relieve pain for the user, a pressure greater than the user's arterial systolic pressure is required to push the painkiller into the user's hepatic artery. Therefore, the output pressure of the analgesic pump can be set to a value exceeding the user's arterial systolic pressure according to the arterial systolic pressure of the user to be treated, so as to successfully push the painkiller into the hepatic artery of the user to be treated to relieve pain for the user.

[0076] Step S40: Generate a drug infusion strategy based on the drug infusion volume range and the analgesia pump output pressure.

[0077] It can be understood that the above-mentioned drug infusion strategy can be a strategy adopted when delivering the drug to be infused to the user.

[0078] Step S50: delivering the drug to be infused from the first drug storage device to the hepatic artery of the user to be treated according to the drug infusion strategy.

[0079] In this embodiment, the first pump body 5 in the analgesic pump can use the analgesic pump output pressure set in the drug infusion strategy to deliver the drug to be infused within the drug infusion volume range from the first drug storage device 2 to the hepatic artery of the user to be treated.

[0080] Furthermore, the step S50 also includes: according to the drug infusion strategy, delivering the drug to be infused from the first drug storage device to the hepatic artery of the user to be treated, and at the same time delivering the chemotherapy drug from the second drug storage device to the hepatic artery of the user to be treated, wherein the second drug storage device is a container for storing the chemotherapy drug.

[0081] It should be understood that in addition to delivering analgesics to the user, the analgesic pump can also deliver chemotherapy drugs stored in the second drug storage device 3 together with the analgesics into the user's hepatic artery through the second pump body 6, so as to provide analgesic treatment to the user while treating the user, thereby reducing the user's pain and increasing the user's comfort.

[0082] The present embodiment provides a method for controlling an arterial analgesia pump that pumps lidocaine, the method discloses determining a drug infusion level corresponding to the drug to be infused according to the pain level of the user to be treated; determining a drug infusion volume range corresponding to the drug to be infused based on the drug infusion level; determining the user's arterial systolic pressure according to the diagnostic information of the user to be treated, and determining the analgesia pump output pressure according to the user's arterial systolic pressure; generating a drug infusion strategy based on the drug infusion volume range and the analgesia pump output pressure; and delivering the drug to be infused from a first drug storage device to the hepatic artery of the user to be treated according to the drug infusion strategy; since the present embodiment generates a drug infusion strategy based on the drug infusion volume corresponding to the drug to be infused and the analgesia pump output pressure, and delivers the drug to be infused to the hepatic artery of the user to be treated through the drug infusion strategy, the technical problem that the drug administration control of the analgesia pump using a single and fixed control method in the prior art often fails to meet treatment needs and has poor safety is solved.

[0083] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , Figure 3 A flow chart of Example 2 of the control method for an arterial analgesia pump for pumping lidocaine is provided in the present application.

[0084] In this embodiment, step S20 includes steps S201 to S203:

[0085] Step S201: obtaining the drug concentration corresponding to the drug to be infused based on the drug infusion level.

[0086] It should be noted that the above-mentioned drug concentration is the concentration of the drug to be infused. In this embodiment, the drug concentrations corresponding to different drug infusion levels are usually different. Therefore, the drug concentration of the drug to be infused can be determined according to the drug infusion level of the drug to be infused. Then, the medical staff can pre-configure the drug to be infused according to the drug concentration and store it in the first drug storage device 2 in the analgesic pump after the configuration is completed.

[0087] Step S202: Determine an upper limit value and a lower limit value of blood drug concentration based on the drug concentration.

[0088] It should be noted that the above-mentioned upper limit of blood drug concentration may be the upper limit of the total concentration of the drug in plasma after absorption; correspondingly, the above-mentioned lower limit of blood drug concentration may be the lower limit of the total concentration of the drug in plasma after absorption. In this embodiment, the upper limit of blood drug concentration and the lower limit of blood drug concentration may be obtained based on the prediction of the drug concentration of the drug to be infused, and the specific prediction method is not limited in this embodiment.

[0089] Step S203: determining a drug infusion volume range corresponding to the drug to be infused based on the blood drug concentration upper limit value and the blood drug concentration lower limit value.

[0090] Specifically, the step S203 includes: determining the apparent distribution volume corresponding to the drug to be infused according to the drug infusion level; determining the first drug infusion amount based on the apparent distribution volume and the lower limit of the blood drug concentration; determining the second drug infusion amount based on the apparent distribution volume and the upper limit of the blood drug concentration; determining the drug infusion amount range corresponding to the drug to be infused according to the first drug infusion amount and the second drug infusion amount.

[0091] It should be noted that the apparent distribution volume corresponding to the above-mentioned drug to be infused can be the distribution degree of the drug to be infused in the user's body under ideal conditions. In this embodiment, different apparent distribution volumes can be set for different drug infusion levels, that is, in this solution, there is a certain mapping relationship between the user's pain level, the drug infusion level of the drug to be infused, and the apparent distribution volume. At this time, a mapping relationship table can be established according to the mapping relationship, so that the apparent distribution volume corresponding to the drug to be infused can be directly queried from the mapping relationship table according to the drug infusion level of the drug to be infused, and the drug infusion amount of the drug to be infused can be calculated according to the apparent distribution volume of the drug to be infused and the blood drug concentration. Among them, the calculation formula for the drug infusion amount is: A=Vd*C, where A is the drug infusion amount, Vd is the apparent distribution volume, and C is the blood drug concentration.

[0092] It should be noted that the first drug infusion amount may be the minimum amount of the drug that needs to be delivered to the user this time; and the second drug infusion amount may be the maximum amount of the drug that can be delivered to the user this time.

[0093] In actual applications, the device can determine the apparent distribution volume corresponding to the drug to be infused by querying a pre-established mapping relationship table, and calculate the first drug infusion amount based on the apparent distribution volume and the lower limit of the blood drug concentration through the drug infusion amount calculation formula. At the same time, the second drug infusion amount is calculated based on the apparent distribution volume and the upper limit of the blood drug concentration through the drug infusion amount calculation formula. Finally, the first drug infusion amount and the second drug infusion amount constitute the drug infusion amount range corresponding to the drug to be infused.

[0094] Furthermore, after step S50, the method further includes: monitoring the current infusion volume of the drug to be infused in real time.

[0095] When the current infusion amount is lower than the first drug infusion amount and the duration exceeds a first preset duration, the drug infusion level is reduced to obtain an updated drug infusion level, and the process returns to the step of determining the drug infusion amount range corresponding to the drug to be infused based on the drug infusion level.

[0096] Alternatively, when the current infusion volume is higher than the second drug infusion volume and the duration exceeds a second preset duration, the drug infusion level is increased to obtain an updated drug infusion level, and the process returns to the step of determining the drug infusion volume range corresponding to the drug to be infused based on the drug infusion level.

[0097] It should be understood that the above-mentioned current infusion volume may be the continuous infusion volume of the drug to be infused at the current moment which is infused to the user at a continuous infusion speed.

[0098] In this embodiment, if the current infusion amount of the drug to be infused is continuously (for a duration exceeding the first preset duration) lower than the first drug infusion amount, it means that the current infusion amount of the drug to be infused cannot meet the ideal infusion amount of the corresponding drug infusion level, and the drug infusion level can be lowered at this time; correspondingly, if the current infusion amount of the drug to be infused is continuously (for a duration exceeding the second preset duration) higher than the second drug infusion amount, it means that the current infusion amount of the drug to be infused exceeds the ideal infusion amount of the corresponding drug infusion level, and the drug infusion level can be lowered at this time, so that the drug infusion level can be adjusted in these two cases, so that the infusion amount of the drug to be infused can be adjusted accordingly according to the adjusted infusion level, so as to maximize the effect of the drug. Among them, the specific values ​​of the first preset duration and the second preset duration in this embodiment can be set according to actual conditions, and this embodiment does not limit this.

[0099] In this embodiment, it is disclosed that the drug concentration corresponding to the drug to be infused is obtained based on the drug infusion level; the upper limit value and the lower limit value of the blood drug concentration are determined based on the drug concentration; and the drug infusion amount range corresponding to the drug to be infused is determined based on the upper limit value and the lower limit value of the blood drug concentration, so that a reasonable and effective drug infusion strategy can be generated according to the drug infusion amount range to treat the user, thereby improving the user's treatment experience.

[0100] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 4 , Figure 4 This is a flow chart of Example 3 of the control method of an arterial analgesia pump for pumping lidocaine in the present application.

[0101] In this embodiment, before step S40, the control method of the arterial analgesia pump pumping lidocaine further includes steps S401 to S403:

[0102] Step S401: obtaining in real time the current pain index data corresponding to the current surgical site of the user to be treated.

[0103] It should be understood that the above-mentioned current surgical site is the site where the user to be treated is currently undergoing surgery.

[0104] It should be noted that the above current pain index data can be the potential change amplitude data of the electromyographic signal corresponding to the muscles around the current surgical site, or other data that can be used to characterize the current pain level of the user, and this embodiment does not limit this. Among them, the range around the current surgical site can be set according to actual conditions. For example, in this embodiment, it can be set to a range of 2 cm outside the surgical site.

[0105] Step S402: determining standard pain index data according to the pain level.

[0106] It can be understood that the above-mentioned standard pain index data can be the pain index data corresponding to when the user is in different pain levels under normal circumstances. In this embodiment, the standard pain index data can be the potential change amplitude data of the electromyographic signal when the user is in different pain levels under normal circumstances, wherein the standard pain index data can also be a data range, which is not limited in this embodiment.

[0107] Step S403: determining a target administration rate corresponding to the drug to be infused based on the current pain index data and the standard pain index data.

[0108] It should be noted that the above-mentioned target drug delivery speed can be the speed at which the analgesic pump delivers the drug to be infused to the user to be treated. In this embodiment, the speed at which the analgesic pump delivers the drug is usually different when the user is at different pain levels, and the user's pain level usually changes in real time when the analgesic pump delivers the drug to the user. Therefore, in this embodiment, the user's current pain index data can be collected in real time, and the user's current pain index data can be compared with the standard pain index data to determine the user's current pain level, so that the target drug delivery speed of the current analgesic pump delivering the drug can be determined as the drug delivery speed corresponding to the pain level.

[0109] Accordingly, the step S40 includes:

[0110] Step S40': generating a drug infusion strategy based on the target drug administration rate, the drug infusion volume range and the analgesia pump output pressure.

[0111] It should be understood that after determining the target drug delivery rate corresponding to the drug to be infused by the analgesic pump, a drug infusion strategy can be generated based on the target drug delivery rate, drug infusion volume range and analgesic pump output pressure, so that subsequent analgesic pumps can deliver the drug to be infused to the user at the target drug delivery rate.

[0112] Furthermore, after step S50, the method also includes: acquiring the current pain level of the user to be treated in real time, and comparing the current pain level with the pain level; if the current pain level is higher than the pain level, increasing the target drug administration rate, obtaining an updated target drug administration rate, and executing the step of generating a drug infusion strategy based on the target drug administration rate, the drug infusion volume range and the analgesic pump output pressure.

[0113] In actual applications, this embodiment can also obtain the user's pain level in real time while the pain pump is delivering drugs to the user, and compare the current pain level with the previous pain level. If the user's current pain level is higher than the previous pain level, it means that the user's pain has not been relieved. At this time, the drug administration speed can be increased to speed up the relief of the user's pain.

[0114] In this embodiment, the real-time acquisition of current pain index data corresponding to the current surgical site of the user to be treated is disclosed; standard pain index data is determined according to the pain level; the target drug administration speed corresponding to the drug to be infused is determined based on the current pain index data and the standard pain index data; and a drug infusion strategy is generated based on the target drug administration speed, the drug infusion volume range and the analgesic pump output pressure, thereby improving the accuracy of the generated drug infusion strategy and further improving the treatment effect on the user.

[0115] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the control method of the arterial analgesia pump for pumping lidocaine in the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0116] The present application also provides a control system for an arterial analgesia pump that pumps lidocaine.
