Description

Technical Field

[0001] The invention relates to the field of electronic drug injection pumps, and in particular to a method for using an electronic drug injection pump with bubble adaptive alarm and accumulation detection. Background Art

[0002] During use of existing medical electronic infusion pumps, in order to prevent bubbles from being infused into the patient's body during the infusion process and causing adverse reactions in the patient, a bubble sensor is usually used in the product design to detect bubbles in the infusion line or liquid storage device.

[0003] Generally speaking, a small amount of bubbles injected during clinical medication will not cause harm to the patient, but when the cumulative amount of bubbles injected exceeds a certain amount, it is easy to cause gas embolism, thereby causing harm to the patient. In addition, some clinical drugs are prone to small bubbles, and because of the deviation in the accuracy of the infusion device, it is easy to infuse the drug solution in advance. These situations are easy to cause the infusion pump to inject bubbles into the patient's body, thereby causing the risk of gas embolism to the patient. In addition, a significant difference between the electronic injection pump and the volumetric infusion pump is that it is difficult to completely remove the bubbles in the storage bag after injecting the drug solution into the storage bag when using the electronic injection pump in clinical practice, and the working mode of the electronic injection pump during infusion is different from that of the volumetric infusion pump, which makes it easy for small bubbles to be injected into the patient during the infusion of the electronic injection pump. Finally, patients of different age groups have different levels of acceptance of the amount of bubble input. Although the bubble sensor can achieve a relatively high detection sensitivity, if the bubble alarm is frequently sounded during clinical medication, it will significantly affect the patient's mood and increase the burden of clinical medical staff to deal with such alarms. In severe cases, it may even lead to conflicts between doctors and patients and affect the treatment of patients. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a method for using an electronic injection pump with bubble adaptive alarm and accumulation detection.

[0005] The method for using the electronic drug injection pump with bubble adaptive alarm and accumulation detection in the present invention comprises the following steps:

[0006] S1: Start;

[0007] S2: Set the single bubble alarm priority and cumulative bubble threshold value B;

[0008] S3: Set infusion parameters;

[0009] S4: infusion;

[0010] S5: Determine whether bubbles are detected. If yes, go to S6; if no, go to S7;

[0011] S6: Accumulate the detected bubble volume C, and go to S9:

[0012] S7: Has the bubble alarm been triggered? If yes, go to S8; if no, go to S4;

[0013] S8: Automatically clear bubble alarm;

[0014] S9: Does the cumulative detected bubble volume C reach the cumulative bubble threshold value B? If yes, go to S10; if no, go to S11;

[0015] S10: Triggering the accumulated bubble alarm;

[0016] S11: Is the single bubble alarm a low priority alarm? If yes, go to S4; if no, go to S12;

[0017] S12: stop infusion;

[0018] S13: Determine whether retesting is required? If yes, go to S14; if no, go to S12;

[0019] S14: Determine whether bubbles are detected. If yes, go to S12; if no, go to S15;

[0020] S15: Automatically clear the bubble alarm and go to S4.

[0021] In the above solution, the electronic injection pump adopts a highly sensitive bubble sensor.

[0022] In the above solution, the electronic injection pump can be configured to accumulate bubble volume, and the amount of bubbles detected needs to be accumulated during infusion.

[0023] In the above scheme, the priority in S11 can be set, which can be set to low priority or high priority, and the setting can be memorized and saved.

[0024] The advantages and beneficial effects of the present invention are as follows: the present invention provides a method for using an electronic drug injection pump with bubble adaptive alarm and cumulative detection, which effectively solves the problem of bubble input control risk during clinical use of existing electronic drug injection pumps.

[0025] 1. Accumulated bubble detection: Accumulated bubble detection effectively solves the problem of frequent interruptions of drug administration caused by frequent alarms of small bubbles in clinical practice. This design can truly and effectively control the risk of clinical bubble input;

[0026] 2. Single bubble adaptive detection, continue infusion when low priority, stop infusion when high priority, and automatically eliminate bubble alarm when no bubble is detected again. This design can significantly reduce the workload of clinical handling of small bubble alarms under controllable risks, while reducing the impact of alarms on patients' emotions, ensuring the continuity of infusion and drug administration;

[0027] 3. The amount of cumulative bubble detection can be set. This design can solve the different differences in the acceptable amount of bubble input among different types of patients in clinical practice. It provides convenience for clinical use and can more effectively and differentially control the risk of bubble input.

[0028] 4. Accumulated bubble alarm. This design requires clinical human intervention to eliminate bubbles in the pipeline and liquid storage device, further ensuring the safety of drug administration. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0030] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0031] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0032] like Figure 1 As shown, the present invention is a method for using an electronic injection pump with bubble adaptive alarm and accumulation detection in the present invention, comprising the following steps:

[0033] S1: Start;

[0034] S2: Set the single bubble alarm priority and cumulative bubble threshold value B;

[0035] S3: Set infusion parameters;

[0036] S4: infusion;

[0037] S5: Determine whether bubbles are detected. If yes, go to S6; if no, go to S7;

[0038] S6: Accumulate the detected bubble volume C, and go to S9:

[0039] S7: Has the bubble alarm been triggered? If yes, go to S8; if no, go to S4;

[0040] S8: Automatically clear bubble alarm;

[0041] S9: Does the cumulative detected bubble volume C reach the cumulative bubble threshold value B? If yes, go to S10; if no, go to S11;

[0042] S10: Triggering the accumulated bubble alarm;

[0043] S11: Is the single bubble alarm a low priority alarm? If yes, go to S4; if no, go to S12;

[0044] S12: stop infusion;

[0045] S13: Determine whether retesting is required? If yes, go to S14; if no, go to S12;

[0046] S14: Determine whether bubbles are detected. If yes, go to S12; if no, go to S15;

[0047] S15: Automatically clear the bubble alarm and go to S4.

[0048] The electronic infusion pump adopts a highly sensitive bubble sensor, which can detect small bubbles in the infusion line, such as A μL (eg, 50 μL or other values).

[0049] The electronic infusion pump can be configured with a cumulative bubble volume, such as B (eg, 5 mL or other values), and the detected bubble volume C needs to be accumulated during infusion.

[0050] In the above scheme, the priority in S11 can be set, which can be set to low priority or high priority, and the setting can be memorized and saved.

[0051] The electronic injection pump can be configured to indicate whether to indicate the accumulated amount of bubbles input during the bubble alarm. When the bubble sensor detects bubbles during infusion, the bubble alarm will be triggered.

[0052] When the accumulated bubble volume C is less than the set accumulated bubble volume B, after the product triggers the bubble alarm, if the bubble alarm is set as a low priority alarm, the product needs to continue infusing. If no bubbles are detected during the subsequent infusion, the bubble alarm will automatically be eliminated. If the bubble alarm is set as a high priority alarm, the product needs to stop infusing, and then regularly check whether the bubbles still exist according to the current infusion rate. If they no longer exist (it may be because small bubbles have crossed the bubble sensor during the last infusion, or there is subsequent clinical intervention that caused the bubbles to disappear), the alarm will be automatically eliminated and the infusion will continue, otherwise the bubble alarm will continue; if the product is configured to display the accumulated input bubble volume, the value will be displayed on the bubble alarm interface;

[0053] When the accumulated bubble volume C reaches the set accumulated bubble volume B, the product triggers a high-priority accumulated bubble alarm, stops the infusion, and prohibits continued infusion in the clinic; subsequent infusion is allowed only after the exhaust function on the product is executed or the liquid storage device is removed (generally electronic injection pumps have sensors that can detect this operation).

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
