1, drug preparation: according to the doctor's advice and the patient's condition, as well as the duration of medication, determine the appropriate syringe and prepare appropriate drugs, such as dopamine and adrenaline;

2. Place the syringe: place the syringe filled with medicine on the micropump and fix it;

3. Start: Turn on the power supply and start the injection pump, so that the drug can be pumped into the patient for treatment continuously and stably.

Second, matters needing attention:

1, Do not touch: Do not touch the micropump at will, so as to avoid loosening of the instrument and waste or extravasation of drugs. When patients need to go to the toilet or do activities, they should try to avoid causing too much influence on pipes or micropumps. When the micropump is found to have drug extravasation or give an alarm for unknown reasons, the medical staff should be called in time for treatment;

2. Pay attention to safety: microinjection pump is usually driven by electricity. Whether it is an external power supply or a built-in battery, you should pay attention to safety when using micro-injection pump. Do not place too many sundries near the power supply, especially water cups and kettles, to avoid the danger of electric shock;

3. Smooth pipeline: During operation, ensure smooth pipeline, and do not fold or squeeze the pipeline. The whole infusion line is exposed as much as possible for inspection. If it is found that the infusion pipeline is blocked and the drug flow is not smooth, the medical staff should be called in time for treatment;

4. Close observation: When operating the micropump, observe the patient's condition at any time. If the patient suddenly loses consciousness, abnormal signs and other abnormal situations, he should call the medical staff in time to deal with them.
