How to use the microinjection pump to work on the artificial airway?
Jul 11, 2018

The micro-injection pump pumps a small amount of liquid accurately, microscopically, uniformly and continuously into the body. The operation is convenient, timed and quantitative. The concentration and speed of the drug can be adjusted at any time according to the needs of the disease, so that the drug can maintain an effective blood concentration in the body. Pumps to rescue critically ill patients can reduce the workload of nurses, improve work efficiency, and cooperate with doctors in an accurate, safe and effective manner. The injection speed of the micro-injection pump is calculated in milliliters per hour, the maximum is 99.9ml/h, and the minimum is 0.1ml/h. If it is a common drug, 100ml per hour is completely no problem, and some such as vasoactive drugs Be especially careful when using it. Pay attention to the decimal point problem. It is easy to misplace 0.5ml into 5ml, or 5ml can be mishandled into 50ml, which may have serious consequences for the patient.

There are 3 red alarm keys on the micro syringe pump: NEARLY EMPTY, EMPTY and OCCLUSION. It is necessary to understand the meaning of these 3 key alarms and the method of alarm elimination.

(1) NEARLY EMPTY: There is still 1-2ml of liquid in the syringe when the alarm is given, reminding you that it is about to be used up. If it is continuous medication, it will give you the time of chemical treatment. At this time, do not press STOP button to avoid key drugs. Stop entering the affected condition, press the silence button to ensure that the liquid continues to maintain an effective concentration in the blood.

(2) EMPTY: When the alarm prompt is completely used up, press the STOP button to silence.

(3) OCCLUSION: The alarm indicates that the pipeline is blocked. It is necessary to find out the cause in time. One is that the needle is blocked, the blood can be pumped back, the heparin solution can be pushed, and even the venous access can be reconstructed; the second is the blockage of the pipeline, the compression and reflexion, the misplacement of the three-way switch, and the use of multiple micro-injection pumps for all the veins. The cause is to relieve the fault and open the venous access; the third is to take the needle out of the blood vessel, stop the medication immediately, and reconstruct the venous access; the fourth is the failure of the microinjection pump itself, which needs to be repaired.
