Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical devices and intelligent infusion control, and more specifically to an intelligent electronic infusion pump and a control method thereof. Background Art
[0002] An electronic infusion pump is a micro-infusion device, which generally includes a pump head, a fluid storage box and an infusion pipeline, as well as an automatic dosing button. Common parameters include the total amount of liquid medicine, the first dose, the continuous dose, the single dose, the lock time and the limit amount. In the existing model, if pain occurs, an additional single dose can be administered through the automatic dosing button. After a single dose, a lock time will be entered. Due to individual differences between different individuals, if the previous single dose is too small, it will lead to insufficient analgesia. Multiple ineffective self-controlled dosing will occur during the lock time. If the single dose is not increased, the state of insufficient analgesia will continue to exist, which is not conducive to pain control. Summary of the invention
[0003] In view of the deficiencies in the prior art, the present invention provides an intelligent electronic infusion pump and a control method thereof, which can automatically increase the next single medication dose to improve analgesia when insufficient analgesia occurs, reduce the occurrence of insufficient analgesia, and meet individualized analgesia needs.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent electronic infusion pump, comprising a pump head, a liquid storage box, an infusion pipeline and an electronic control system; wherein the control system monitors the number T of ineffective self-controlled drug administration by the patient within the lock-in time, and automatically increases the effective self-controlled drug administration amount for the self-controlled drug administration signal that appears again within a certain period of time after the end of the lock-in time, based on the patient's high demand for analgesic drugs reflected by the number of times.
[0005] Preferably, the number of invalid self-controlled drug administration T only counts the invalid number of times in the period from a certain time after the lock time starts, such as 5 minutes, to the end of the lock time. Since the first 5 minutes of a lock time is the onset time of the analgesic drug after self-controlled drug administration, the invalid number of self-controls in this period cannot accurately reflect the state of insufficient analgesia and needs to be eliminated.
[0006] Preferably, the greater the number of ineffective self-controlled drug administration times T within the previous lock-in time, the greater the amount of enhanced self-controlled drug administration that occurs again within the set time after the lock-in time ends.
[0007] Preferably, if the number T of consecutive N locking cycles reaches 1 or more, the basic self-controlled drug administration amount is automatically increased.
[0008] Preferably, if the infusion volume for a certain period of time is lower than a preset value, the basal self-controlled drug administration volume is automatically reduced.
[0009] Preferably, the enhanced self-controlled medication amount and the basal self-controlled medication amount do not exceed a preset maximum value.
[0010] The present invention also includes a lock time timer, an analgesia high demand state timer and an invalid self-control times T counter; The locking time timer is used to time the locking time after effective self-controlled infusion, and the invalid self-control number T counter is used to record the invalid number of times that occur during the locking time. When the invalid number T during this locking time is not 0, the analgesia high demand state timer is started after the locking time timer finishes working. The self-control signal that appears during the high demand state time is combined with the T value to increase the self-controlled medication amount this time. The self-control signal that appears after the high demand state timer finishes working is used to infuse the basic amount of self-controlled medication.
[0011] This aspect also includes an infusion volume monitor. In the existing technical solution, during the operation of the infusion pump, the current total infusion volume is displayed by displaying information about the infused volume or the remaining volume. The infusion volume monitor is used to monitor the total amount infused within the set time. For example, when the total infusion volume within 1 hour is less than 0.2 ml, the basic self-controlled medication volume is automatically reduced.
[0012] The infusion device of the present invention also has a network system, and also includes a central monitoring server, a display screen, a signal receiving device connected to the central monitoring server for communication, and a signal transmitting device provided on the pump head, wherein the signal transmitting device is used to transmit data to the central monitoring server.
[0013] The present invention also provides another technical solution: a method for an intelligent electronic infusion pump, the steps are as follows: Step 1, determine whether there is an automatic control activation signal: if yes, proceed to step 2, if no, continue to step 1; Step 2, perform self-controlled infusion, start the lock time timer, and execute step 3; Step 3, determine whether the lock timer is completed; if yes, go to step 6; if no, go to step 4; Step 4, determine whether there is an automatic control activation signal; if yes, proceed to step 5; if no, continue to step 3; Step 5, invalid self-control times counter T value + 1, and execute step 3; Step 6, determine whether the T value is 0: if yes, go to step 1; if no, go to step 7; Step 7, start the high demand state timer, and execute step 8; Step 8, determine whether the high demand state timer is completed; if yes, go to step 9; if no, go to step 10; Step 9, end the current high demand state and execute step 1; Step 10, determine whether there is an automatic control activation signal; if yes, proceed to step 11; if no, continue to step 8; Step 11, increase the self-controlled medication amount based on the T value, end the high demand state and execute step 2.
[0014] Compared with the prior art, the present invention has the following advantages and effects: it can perform individualized self-controlled drug infusion, automatically identify the inadequate analgesia state reflected by ineffective self-control, and automatically increase the dosage to improve the analgesic effect. When an extremely low infusion state occurs, the basic dosage is automatically reduced to reduce dose-dependent side effects. Compared with the prior art solutions, it can provide better analgesic effects and fewer side effects, achieving precise analgesia. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a flow chart of an intelligent electronic infusion pump control method in an embodiment of the present invention. DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the present invention are clearly and completely described below. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.
[0017] Example 1.
[0018] An intelligent electronic infusion pump comprises a pump head, a liquid storage box, an infusion pipeline and an electronic control system; the control system monitors the number T of invalid self-controlled drug administration by a patient within a lock-in time, and automatically increases the effective self-controlled drug administration amount for the self-controlled drug administration signal that appears again within a certain period of time after the lock-in time ends, based on the patient's high demand for analgesic drugs reflected by the number.
[0019] Preferably, the number of invalid self-controlled drug administration T only counts the invalid number of times in the period from a certain time after the lock time starts, such as 5 minutes, to the end of the lock time. Since the first 5 minutes of a lock time is the onset time of the analgesic drug after self-controlled drug administration, the invalid number of self-controls in this period cannot accurately reflect the state of insufficient analgesia and needs to be eliminated.
[0020] Preferably, the greater the number of ineffective self-controlled drug administration times T within the previous lock-in time, the greater the amount of enhanced self-controlled drug administration that occurs again within the set time after the lock-in time ends.
[0021] Preferably, if the number T of consecutive N locking cycles reaches 1 or more, the basic self-controlled drug administration amount is automatically increased.
[0022] Preferably, if the infusion volume for a certain period of time is lower than a preset value, the basal self-controlled drug administration volume is automatically reduced.
[0023] Preferably, the enhanced self-controlled medication amount and the basal self-controlled medication amount do not exceed a preset maximum value.
[0024] The present invention also includes a lock time timer, an analgesia high demand state timer and an invalid self-control times T counter; The locking time timer is used to time the locking time after effective self-controlled infusion, and the invalid self-control number T counter is used to record the invalid number of times that occur during the locking time. When the invalid number T during this locking time is not 0, the analgesia high demand state timer is started after the locking time timer finishes working. The self-control signal that appears during the high demand state time is combined with the T value to increase the self-controlled medication amount this time. The self-control signal that appears after the high demand state timer finishes working is used to infuse the basic amount of self-controlled medication.
[0025] This aspect also includes an infusion volume monitor. In the existing technical solution, during the operation of the infusion pump, the current total infusion volume is displayed by displaying information about the infused volume or the remaining volume. The infusion volume monitor is used to monitor the total amount infused within the set time. For example, when the total infusion volume within 1 hour is less than 0.2 ml, the basic self-controlled medication volume is automatically reduced.
[0026] The infusion device of the present invention also has a network system, and also includes a central monitoring server, a display screen, a signal receiving device connected to the central monitoring server for communication, and a signal transmitting device provided on the pump head, wherein the signal transmitting device is used to transmit data to the central monitoring server.
[0027] The present invention also provides another technical solution: a method for an intelligent electronic infusion pump, the steps are as follows: Step 1, determine whether there is an automatic control activation signal: if yes, proceed to step 2, if no, continue to step 1; Step 2, perform self-controlled infusion, start the lock time timer, and execute step 3; Step 3, determine whether the lock timer is completed; if yes, go to step 6; if no, go to step 4; Step 4, determine whether there is an automatic control activation signal; if yes, proceed to step 5; if no, continue to step 3; Step 5, invalid self-control times counter T value + 1, and execute step 3; Step 6, determine whether the T value is 0: if yes, go to step 1; if no, go to step 7; Step 7, start the high demand state timer, and execute step 8; Step 8, determine whether the high demand state timer is completed; if yes, go to step 9; if no, go to step 10; Step 9, end the current high demand state and execute step 1; Step 10, determine whether there is an automatic control activation signal; if yes, proceed to step 11; if no, continue to step 8; Step 11, increase the self-controlled medication amount based on the T value, end the high demand state and execute step 2.
[0028] Example 2.
[0029] This embodiment operates the intelligent electronic infusion pump in Embodiment 1: Set the total infusion volume to 100ml, the first volume to 2ml, the continuous volume to 2ml / h, the basic self-controlled drug volume to 1.5ml, the lock time to 15 minutes, and the limit volume to 15ml / h. The number of invalid self-controls within the lock time of 5-15 minutes is calculated into the T value. When the lock time ends when the T value is not 0, the 15 minutes after the end of the lock time is a high demand state. The self-controlled drug administration during this period is infused at the basic self-controlled drug volume * (T+1), and the maximum single drug volume is 4.5ml.
[0030] The operation started at 8:00. Pain occurred at 8:20 and self-controlled medication of 1.5 ml was given. Ineffective self-control occurred at 8:22, 8:24, 8:29, and 8:32. The lock time ended at 8:35. The T value was 2 and the high demand state was entered. Self-controlled medication occurred again at 8:45. The self-controlled medication amount this time was 3 times the basic amount, that is, 4.5 ml. Then, there were two invalid self-controls at 8:48 and 8:55. After 9:00, the high demand state was entered. Self-control appeared at 9:10. The self-controlled medication amount this time was 2 times the basic amount. This time, a single infusion of 3 ml was performed. Then, there were two invalid self-controls at 9:16 and 9:20. After 9:25, the high demand state was entered. Self-control appeared at 9:50. At this time, the high demand state had ended and a single infusion of 1.5 ml was performed.
[0031] Example 3.
[0032] This embodiment operates the intelligent electronic infusion pump in Embodiment 1: Set the total infusion volume to 150ml, the first volume to 2ml, the continuous volume to 2ml / h, the basic self-controlled drug administration volume to 1ml, the lock time to 10 minutes, and the limit volume to 15ml / h. The number of invalid self-controls within the lock time of 5-10 minutes is calculated into the T value. When the lock time ends when the T value is not 0, the 20 minutes after the end of the lock time is a high demand state. The self-controlled drug administration during this period is infused at the basic self-controlled drug administration volume * (T+1). If three consecutive T values reach 1 or above, the basic self-controlled drug administration volume will be automatically increased by 0.5ml. If the cumulative infusion volume for 1 hour is less than 0.2ml, the basic self-controlled drug administration volume will be automatically reduced by 0.5ml. The maximum single drug administration volume is 4ml, and the minimum is 0.5ml.
[0033] The operation started at 8:00. Pain appeared at 8:20 and self-controlled medication of 1 ml was given. Ineffective self-control appeared 3 times at 8:22, 8:24, and 8:29. The lock time ended at 8:30. The T value was 1 this time, and the high demand state was entered. Self-controlled medication appeared again at 8:35. The self-controlled medication amount this time was 2 times the basic amount, that is, 2 ml. Then, ineffective self-control appeared 3 times at 8:41, 8:42, and 8:44. The lock time ended at 8:45. The T value was 3 this time, and the high demand state was entered. Self-control appeared at 8:50. The self-controlled medication amount this time was 4 times the basic amount, that is, 4 ml. Then, ineffective self-control appeared 5 times at 8:51, 8:56, 8:57, 8:58, and 8:59. The lock time ended at 9:00. The T value was 4 this time, and the high demand state was entered. Self-control appeared at 9:05. The self-controlled medication amount this time was 4 times the basic amount, that is, 4 ml. Since T reaches 1 or above for three consecutive times at this time, the basic self-controlled drug administration volume is automatically increased by 0.5ml, that is, the basic self-controlled drug administration volume thereafter is 1.5ml. The high demand state ends at 9:25, and 1.5ml of self-controlled drug administration is performed at 9:30. Two invalid self-controls occur at 9:32 and 9:34. The lock time ends at 9:40, and the T value this time is 0. 1.5ml of self-controlled drug administration occurs again at 9:45. By 13:00, it is monitored that the cumulative infusion volume for nearly 1 hour is less than 0.2ml, and the basic self-controlled drug administration volume is automatically reduced by 0.5ml, that is, the basic self-controlled drug administration volume thereafter is 1ml. Although embodiments of the present invention have been shown and described, for those of ordinary skill in the art, various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and concepts of the present invention, and the scope of the present invention is determined by the attached claims and their equivalents.
