[0050] The core idea of ​​the present invention is to provide a control method for an automatic infusion device, an automatic infusion device, an automatic infusion system and a readable storage medium, which can solve the safety problems existing in opening the self-controlled drug administration to patients, allowing patients to replenish the dosage according to their own conditions, and ensuring the safety of infusion to the greatest extent. It should be noted that the control method and readable storage medium of the automatic infusion device provided by the present invention can be applied to the automatic infusion device and automatic infusion system provided by the present invention. It should also be noted that, as can be understood by those skilled in the art, the liquid medicines that can be delivered by the automatic infusion device and the automatic infusion system provided by the present invention include but are not limited to analgesic liquid medicines.

[0051] For ease of understanding, the controlled infusion device provided by the present invention is first described, and then the control method of the automatic infusion device, the automatic infusion system and the readable storage medium provided by the present invention are described one by one.

[0052] To realize the above idea, the present invention provides an automatic infusion device, please refer to Figure 1 , which is a schematic diagram of the block structure of an automatic infusion device provided by one embodiment of the present invention. Figure 1As shown, the automatic infusion device 100 provided by the present invention includes a microprocessor 110, a trigger module 120 and an infusion pump 130, and the trigger module 120 and the infusion pump 130 are both connected to the microprocessor 110 in communication; the trigger module 120 is configured to receive the user's supplementary infusion instruction in real time, and send the supplementary infusion instruction to the microprocessor 110; when the microprocessor 110 does not receive the supplementary infusion instruction, it is configured to obtain the basic infusion parameters according to the preset infusion mode, and send the control instruction to the infusion pump 130 according to the basic infusion parameters; when the microprocessor 110 receives the supplementary infusion instruction, it is configured to perform the following operations: determine the received infusion mode at the current moment; Whether the supplementary infusion instruction is valid; if the supplementary infusion instruction is valid, and the supplementary infusion instruction corresponds to the supplementary infusion parameter, the unit estimated value is obtained by the sum of the basic infusion parameter and the sum of the supplementary infusion parameter within the unit time, and it is judged whether the unit estimated value is less than the preset limit threshold; if the unit estimated value is less than the limit threshold, the microprocessor 110 sends a control instruction to the infusion pump 130 according to the sum of the basic infusion parameter and the supplementary infusion parameter; if the supplementary infusion instruction is invalid or the unit estimated value is not less than (i.e., greater than or equal to) the limit threshold, the control instruction sent by the microprocessor 110 to the infusion pump 130 is consistent with when the supplementary infusion instruction is not received. Therefore, the automatic infusion device 100 provided by the present invention solves the safety problem of opening to patients for self-controlled drug administration, which allows patients to supplement the amount of medicine according to their own situation (for example, patients can supplement the amount of medicine according to their own pain level to solve the pain problem of patients), and can also set the limit threshold and judge whether the supplementary infusion instruction triggered by the user is valid to ensure the safety of infusion to the greatest extent.

[0053] It should be noted that the parameter types of basic infusion parameters, supplementary infusion parameters, unit estimated values, and limit threshold values ​​can be either infusion volume or infusion speed. In order to facilitate control, the data types used by the aforementioned "basic infusion parameters, supplementary infusion parameters, unit estimated values, and limit threshold values" can be consistent with the preset infusion mode. If the infusion mode stores the mapping relationship between the infusion volume and the infusion time at each moment, the data type of "basic infusion parameters, supplementary infusion parameters, unit estimated values, and limit threshold values" can correspond to "basic infusion infusion volume, supplementary infusion volume, unit estimated value, and limit volume threshold value"; if the infusion mode stores the mapping relationship between the infusion speed and the infusion time at each moment, the data type of "basic infusion parameters, supplementary infusion parameters, unit estimated value, and limit threshold value" can correspond to "basic infusion speed, supplementary infusion speed, unit estimated speed, and limit speed threshold value". Correspondingly, the microprocessor sends control instructions to the infusion pump based on the basic infusion parameters and supplementary infusion parameters received, which can be parameters directly calculated based on the basic infusion parameters and supplementary infusion parameters sent to the infusion pump, or data such as rotation speed converted from the basic infusion parameters and supplementary infusion parameters sent to the infusion pump. This application does not limit the specific types of parameter types and control instructions, but is intended to protect the screening, recording and feedback of the effectiveness of supplementary infusion instructions, so as to ensure the patient or user's sense of control over their own pain management under the premise of safety as much as possible, and serve as a data source for the supervisory end 400 to understand and adjust existing setting values, thereby achieving dynamic and safe pain management.

[0054] Specifically, the microprocessor 110 includes a chip with logic operation capability and a circuit corresponding to the chip, and the microprocessor 110 includes one or more signal input terminals and one or more signal output terminals. For example, the microprocessor 110 is a single-chip microcomputer system, which includes a single-chip microcomputer chip of a certain model and a power supply circuit, a crystal oscillator circuit, etc. corresponding to the single-chip microcomputer chip of the model, and the single-chip microcomputer system includes an input terminal / output terminal directly connected to the pin of the single-chip microcomputer chip, and an input terminal / output terminal indirectly connected to the pin of the single-chip microcomputer through a signal adapter (such as a relay). Furthermore, the microprocessor 110 can obtain the total infusion volume of the infusion pump 130 at the current moment (i.e., the sum of the total amount of supplementary infusion parameters and the total amount of basic infusion parameters) according to the built-in sensor of the infusion pump 130, and then calculate the sum of the sum of the supplementary infusion parameters and the sum of the basic infusion parameters of the infusion pump 130 per unit time at the current moment (i.e., the unit estimated value at the current moment) according to the total infusion volume at the current moment and the infusion duration up to the current moment (the time interval between the start time of infusion and the current moment).

[0055] It should be noted that, as can be understood by those skilled in the art, when it is determined that the supplementary infusion instruction received at the current moment is invalid, the infusion pump 130 does not perform supplementary infusion but only performs basic infusion; when it is determined that the sum of the basic infusion parameters and the sum of the supplementary infusion parameters of the infusion pump 130 in unit time before the moment (i.e., the unit estimated value) is greater than or equal to the preset limit threshold, the infusion pump 130 does not perform supplementary infusion but only performs basic infusion (i.e., the control instruction sent by the microprocessor 110 to the infusion pump 130 is consistent with that when the supplementary infusion instruction is not received). It should also be noted that, as can be understood by those skilled in the art, the preset infusion mode can be pre-set by the doctor, and the limit threshold can also be set by the doctor according to the specific situation of the patient, for example, the maximum limit threshold can be set to 125ml / h. It should also be noted that, as those skilled in the art can understand, in some embodiments, the microprocessor 110 can be integrated with the trigger module 120, in other embodiments, the microprocessor 110 can be integrated with the infusion pump 130, and of course, in other embodiments, the microprocessor 110 can also be separately provided, and the present invention does not limit this. In addition, it should also be noted that, as those skilled in the art can understand, the current moment refers to the moment when the microprocessor 110 receives a supplementary infusion instruction each time, that is, the current moment is not a fixed moment, but changes dynamically.

[0056] Please continue to refer to Figure 2 , which is a schematic diagram of the structure of the trigger module 120 provided in one embodiment of the present invention. Figure 2 As shown, in some exemplary embodiments, the trigger module 120 includes a connected button 121 and a timer (not shown in the figure), the timer is configured to calculate the pressing time of the button 121 each time the user presses it, and send the pressing time to the microprocessor 110, and the microprocessor 110 is configured to record the pressing time and send it to the supervisory end 400. Thus, by recording the pressing time of each user and sending it to the supervisory end 400 (see Figure 4), it is convenient for doctors to timely understand the actual needs of patients for supplementary infusion, so as to better realize the precise control of infusion. Specifically, taking the application of the self-controlled infusion device 100 provided by the present invention in the field of analgesia as an example, the longer the user presses the button 121, the higher the patient's pain level is, and conversely, the shorter the user presses the button 121 (still greater than the duration of triggering the button 121), the lower the patient's pain level is. Therefore, by recording the pressing time of the button 121 each time the user presses it, and sending the pressing time to the monitoring end 400, it is convenient for doctors to understand the actual pain level of the patient, so that the doctor can better determine whether it is necessary to change the preset infusion information (including the infusion mode, the limit threshold and the time interval threshold described below, etc.), so as to realize more precise pain control management. For example, when the patient's pain level is high, the doctor can appropriately increase the limit threshold according to a first preset ratio (for example, 110%) based on the limit threshold corresponding to the current moment, but the adjusted limit threshold cannot exceed the maximum limit threshold (for example, 125 ml / h); when the patient's pain level is low, the doctor can appropriately lower the limit threshold according to a second preset ratio (for example, 85%) based on the limit threshold corresponding to the current moment.

[0057] It should be noted that, as can be understood by those skilled in the art, the supervisory terminal 400 can be a hardware device with various operating systems, such as a personal computer, a mobile phone, a tablet computer, etc. The communication connection mode between the supervisory terminal 400 and the microprocessor 110 includes but is not limited to any one of serial communication, Bluetooth communication, 4G communication, 5G communication, WiFi communication, Lora Internet of Things communication, and ZigBee communication.

[0058] Please continue to refer to Figure 2 ,like Figure 2 As shown, in some exemplary embodiments, the trigger module 120 further includes a signal line 122 for communicating with the microprocessor 110. Thus, by using the signal line 122 to realize the communication connection between the trigger module 120 and the microprocessor 110, the cost of the automatic infusion device 100 provided by the present invention can be effectively reduced. It should be noted that, as can be understood by those skilled in the art, in some other embodiments, the trigger module 120 can also communicate with the microprocessor 110 through wireless communication such as Bluetooth, WiFi, etc., and the present invention is not limited to this.

[0059] In some exemplary embodiments, the preset infusion mode includes any one of a continuous infusion mode and a pulse infusion mode, and both the continuous infusion mode and the pulse infusion mode include a mapping relationship between basic infusion parameters and infusion time. Specifically, in the continuous infusion mode, the microprocessor 110 can control the infusion pump 130 to continuously infuse at a first infusion speed until the delivery of the medicine is completed; in the pulse infusion mode, the microprocessor 110 can control the infusion pump 130 to periodically infuse at a second infusion speed until the delivery of the medicine is completed. It should be noted that, as can be understood by those skilled in the art, in some other embodiments, the preset infusion mode can also be any other infusion mode except the continuous infusion mode and the pulse infusion mode, and the present invention is not limited to this.

[0060] In some exemplary embodiments, determining whether the supplemental infusion instruction currently received is valid includes:

[0061] Determine whether the current moment is within the lock time;

[0062] If not, it is determined that the supplementary infusion instruction received at the current moment is valid;

[0063] If so, it is determined that the supplementary infusion instruction received at the current moment is invalid.

[0064] Therefore, by determining whether the current moment is within the lock time, it is possible to accurately determine whether the supplementary infusion instruction received at the current moment is valid, thereby effectively preventing the patient from receiving an excessive amount of medication in a short period of time, and further improving the safety of the patient during the infusion process.

[0065] In some exemplary implementations, determining whether the current moment is within the lock time includes:

[0066] Get the time interval between the current moment and the last time a valid supplementary infusion instruction was received;

[0067] Determining whether the time interval is greater than a preset time interval threshold;

[0068] If not, it is determined that the current time is within the lock time;

[0069] If so, it is determined that the current time is outside the lock time.

[0070] Specifically, the microprocessor 110 automatically records the moment of receiving each supplementary infusion instruction. When the time interval between the moment when the microprocessor 110 currently receives the supplementary infusion instruction (i.e., the current moment) and the last time it receives a valid supplementary infusion instruction is greater than a preset time interval threshold, it is determined that the current moment is outside the lock time, so that the supplementary infusion instruction currently received can be determined to be valid; when the time interval between the moment when the microprocessor 110 currently receives the supplementary infusion instruction (i.e., the current moment) and the last time it receives a valid supplementary infusion instruction is less than or equal to the preset time interval threshold, it is determined that the current moment is within the lock time, so that the supplementary infusion instruction received at the current moment is invalid. It can be seen that by comparing the time interval between the current moment and the last time a valid supplementary infusion instruction was received with the preset time interval threshold to determine whether the current moment is within the lock time, it can effectively prevent patients from infusing excessive drugs in a short period of time, and further improve the safety of patients during the infusion process.

[0071] In some exemplary embodiments, the microprocessor 110 is further configured to record the number of valid supplementary infusion instructions and the number of invalid supplementary infusion instructions received by the microprocessor 110, and send them to the supervisory terminal 400. Therefore, by recording the number of valid supplementary infusion instructions and the number of invalid supplementary infusion instructions received by the microprocessor 110 and sending them to the supervisory terminal 400, it is easier for doctors to timely understand the actual needs of patients for supplementary infusion, so as to better achieve accurate control of infusion. Specifically, taking the application of the automatic infusion device 100 provided by the present invention in the field of analgesia as an example, the more effective supplementary infusion instructions and / or invalid supplementary infusion instructions triggered by the user, the higher the patient's pain level, and conversely, the fewer effective supplementary infusion instructions and / or invalid supplementary infusion instructions triggered by the user, the lower the patient's pain level. Therefore, according to the number of effective supplementary infusion instructions and the number of invalid supplementary infusion instructions received by the microprocessor 110, it can be easier for doctors to understand the patient's actual pain level, so that doctors can more accurately determine whether it is necessary to change the preset infusion information (including infusion mode, limit threshold, time interval threshold, etc.), thereby achieving more accurate pain control management.

[0072] In some exemplary embodiments, the microprocessor 110 is further configured to calculate the user's instruction trigger frequency according to the number of supplementary infusion instructions received within a unit time, and send it to the supervisory end 400. Thus, by calculating the user's instruction trigger frequency and sending it to the supervisory end 400, it can be further facilitated for doctors to understand the patient's actual needs for supplementary infusion, so as to further better achieve precise control of infusion. Specifically, taking the application of the automatic infusion device 100 provided by the present invention in the field of analgesia as an example, the more times the user triggers the supplementary infusion instructions within a unit time (that is, the higher the user's instruction trigger frequency), the higher the patient's pain level, and the fewer times the user triggers the supplementary infusion instructions within a unit time (that is, the lower the user's instruction trigger frequency), the lower the patient's pain level. Therefore, according to the user's instruction trigger frequency, it can effectively help doctors judge the patient's pain level, so that doctors can better determine whether it is necessary to change the preset infusion information (including infusion mode, limit threshold, time interval threshold, etc.) to achieve more accurate pain control management.

[0073] Please continue to refer to Figure 1 ,like Figure 1 As shown, in some exemplary embodiments, the automatic infusion device 100 further includes a human-computer interaction module 140 that is communicatively connected to the microprocessor 110, and the supervisory end 400 inputs the infusion mode and / or the limit threshold and / or the time interval threshold through the human-computer interaction module 140, and sends it to the microprocessor 110. Thus, by setting the human-computer interaction module 140, it is convenient for the supervisory end 400 to set the infusion mode, the limit threshold and / or the time interval threshold, so as to better realize human-computer interaction and facilitate operation. It should be noted that, as can be understood by those skilled in the art, in some embodiments, the human-computer interaction module 140 can be integrated with the infusion pump 130, and in other embodiments, the human-computer interaction module 140 can also be integrated with the microprocessor 110, and the present invention does not limit this. It should also be noted that, as those skilled in the art can understand, the present invention does not limit the specific structure of the human-computer interaction module 140. In some embodiments, the human-computer interaction module 140 can be a touch screen; in other embodiments, the human-computer interaction module 140 can be a multi-function button; in yet other embodiments, the human-computer interaction module 140 can also be a combination structure of a multi-function button + a display screen.

[0074] Please continue to refer to Figure 1 ,like Figure 1As shown, in some exemplary embodiments, the automatic infusion device 100 further includes an alarm module 150 that is communicatively connected to the microprocessor 110, and the alarm module 150 is configured to give an alarm when the unit estimated value is not less than (i.e., greater than or equal to) the limit threshold. Thus, when the microprocessor 110 determines that the sum of the sum of the supplementary infusion parameters and the sum of the basic infusion parameters of the infusion pump 130 within a unit time (i.e., the unit estimated value) is not less than the limit threshold, the microprocessor 110 will send an alarm message to the alarm module 150 to give an alarm through the alarm module 150, thereby prompting the user and / or doctor that the supplementary infusion cannot be performed at this time, so that the doctor can promptly determine whether it is necessary to change the preset infusion information (including the infusion mode, the limit threshold, the time interval threshold, etc.).

[0075] It should be noted that, as can be understood by those skilled in the art, the present invention does not limit the specific alarm form of the alarm module 150. In some embodiments, the alarm module 150 can alarm in the form of sound; in other embodiments, the alarm module 150 can alarm in the form of light; in some other embodiments, the alarm module 150 can alarm in the form of a combination of sound and light. It should also be noted that, as can be understood by those skilled in the art, the present invention does not limit the specific setting position of the alarm module 150. In some embodiments, the alarm module 150 can be integrated with the infusion pump 130; in other embodiments, the alarm module 150 can be integrated with the trigger module 120; in some other embodiments, the alarm module 150 can be integrated with the microprocessor 110.

[0076] In some exemplary embodiments, the difference between the limit threshold and the sum of the basic infusion parameters per unit time is a multiple of the supplemental infusion parameter. Such a setting can maximize the number of times or probability that the supplemental infusion instructions triggered by the patient are recognized as valid triggering instructions, increase the patient's sense of control over the supplemental infusion process within a safe range, and alleviate the patient's anxiety that the supplemental infusion instructions sent by the patient when the pain is severe are judged to be invalid.

[0077] Based on the same inventive concept, the present invention also provides a control method for an automatic infusion device, which is applied to the automatic infusion device 100 provided above. Figure 3 , which is a flow chart of a control method of an automatic infusion device provided by one embodiment of the present invention. Figure 3 As shown, the control method of the automatic infusion device provided by the present invention includes:

[0078] The trigger module 120 is configured to receive a user's supplementary infusion instruction in real time, and send the supplementary infusion instruction to the microprocessor 110;

[0079] When the microprocessor 110 does not receive the supplementary infusion instruction, it is configured to obtain the basic infusion parameters according to the preset infusion mode, and send a control instruction to the infusion pump 130 according to the basic infusion parameters;

[0080] When receiving the supplemental infusion instruction, the microprocessor 110 is configured to perform the following operations:

[0081] Determine whether the supplementary infusion instruction received at the current moment is valid;

[0082] If the supplementary infusion instruction is valid, and the supplementary infusion instruction corresponds to a supplementary infusion parameter, a unit estimated value is obtained by the sum of the basic infusion parameter and the sum of the supplementary infusion parameter within a unit time, and it is determined whether the unit estimated value is less than a preset limit threshold;

[0083] If the unit estimated value is less than the limit threshold, the microprocessor 110 sends a control instruction to the infusion pump 130 according to the sum of the basic infusion parameter and the supplemental infusion parameter;

[0084] If the supplementary infusion instruction is invalid or the unit estimated value is not less than (ie, greater than or equal to) the limit threshold, the control instruction sent by the microprocessor 110 to the infusion pump 130 is consistent with when the supplementary infusion instruction is not received.

[0085] Therefore, the control method of the automatic infusion device provided by the present invention solves the safety problem of allowing patients to self-control drug administration. It allows patients to replenish the dosage of medicine according to their own conditions (for example, patients can replenish the dosage of medicine according to their own pain level to solve the pain problem of patients), and can also ensure the safety of infusion to the greatest extent by setting limit thresholds and judging whether the supplementary infusion instructions triggered by the user are valid.

[0086] It should be noted that, as can be understood by those skilled in the art, when it is determined that the supplementary infusion instruction received at the current moment is invalid, the infusion pump 130 does not perform supplementary infusion but only performs basic infusion; when it is determined that the sum of the sum of the supplementary infusion parameters of the infusion pump 130 per unit time and the sum of the basic infusion parameters (i.e., the unit estimated value) is greater than or equal to the limit threshold, the infusion pump 130 does not perform supplementary infusion but only performs basic infusion.

[0087] In some exemplary embodiments, determining whether the supplemental infusion instruction currently received is valid includes:

[0088] Determine whether the current moment is within the lock time;

[0089] If not, it is determined that the supplementary infusion instruction received at the current moment is valid;

[0090] If so, it is determined that the supplementary infusion instruction received at the current moment is invalid.

[0091] In some exemplary implementations, determining whether the current moment is within the lock time includes:

[0092] Get the time interval between the current moment and the last time a valid supplementary infusion instruction was received;

[0093] Determining whether the time interval is greater than a preset time interval threshold;

[0094] If not, it is determined that the current time is within the lock time;

[0095] If so, it is determined that the current time is outside the lock time.

[0096] In some exemplary embodiments, the control method further includes:

[0097] Record the duration of each time the user presses the button 121 of the trigger module 120 and send it to the supervisory terminal 400; and / or

[0098] Sending the received number of valid supplementary infusion instructions and the number of invalid supplementary infusion instructions to the supervisory terminal 400; and / or

[0099] According to the number of supplementary infusion instructions received within a unit time, the user's instruction triggering frequency is calculated and sent to the monitoring terminal 400.

[0100] In some exemplary embodiments, the control method further includes:

[0101] If the unit estimated value is not less than (ie, greater than or equal to) the limit threshold, the alarm module 150 performs an alarm operation.

[0102] In some exemplary embodiments, the control method further includes:

[0103] The monitoring terminal 400 inputs the infusion mode and / or the limit threshold and / or the time interval threshold through the human-computer interaction module 140 and sends it to the microprocessor 110 .

Since the automatic infusion system provided by the present invention includes the automatic infusion device 100 provided by the present invention, the automatic infusion system provided by the present invention solves the safety problem of self-controlled drug administration for patients, and allows patients to supplement the amount of medicine according to their own conditions (for example, patients can supplement the amount of medicine according to their own pain level to relieve the pain problem of patients), and can also ensure the safety of infusion to the greatest extent by setting a limit threshold and judging whether the supplementary infusion instruction triggered by the user is effective.

[0105] Please continue to refer to Figure 4 ,like Figure 4 As shown, in some exemplary embodiments, the automatic infusion system further includes a monitoring terminal 400 that is communicatively connected to the microprocessor 110, and the monitoring terminal 400 is configured to display at least one of the pressing time of the button 121 pressed each time by the user, the number of valid supplementary infusion instructions, the number of invalid supplementary infusion instructions, and the user's instruction triggering frequency. Thus, by setting the monitoring terminal 400, the problem of information asymmetry between the patient's pain level and the degree of knowledge of the monitoring terminal 400 (e.g., doctor) can be solved, which can help the doctor better understand the patient's pain level, so that the doctor can achieve more accurate pain control management.
