Do You Really Use An Infusion Pump?
The infusion pump is an instrument that can accurately control the number of infusion droplets or the infusion flow rate, and ensure that the drug can be uniformly speeded, the dose of the drug can enter the patient's body accurately and safely, and it is an intelligent infusion device. Affected by the back pressure of the human body and the operator, the infusion is accurate and reliable, which helps to reduce the intensity of clinical nursing work and improve the accuracy, safety and quality of care of the infusion.
It is used for drug bolus injection for adults, children, neonates, etc., for infusion therapy.
1. Insulin is not suitable for infusion pump injection;
2. It is forbidden to use in blood transfusion.
Turn on the pump → open the pump door, snap the infusion hose into the notch of the air bubble sensor, and clamp the infusion tube with the liquid stop clip → install the drip clamp between the nozzle of the Murphy tube and the liquid surface (the pump is used in drip mode or The drip clip alarm function has been turned on) → set the preset volume, speed, pressure and other parameters → start the quick discharge function to remove air bubbles in the infusion tube → connect or indwelling needle → start infusion
Common faults and solutions
Infusion pump common alarm display:
1. Bubble alarm
Cause of failure: There are air bubbles in the pipeline, and the liquid in the solution bottle or bag is empty.
Treatment method: Open the warehouse door and take out the pump tube, discharge air bubbles, and replace with a new infusion bottle.
2. Battery low voltage alarm
Cause of failure: The battery/battery power is insufficient, and the battery charging is invalid.
Solution: Connect to the AC power supply and replace the battery of the same type.
3. Drop alarm
Causes of failure: The liquid in the infusion bottle or bag is empty, the flow rate regulator is not opened, the small cap is not opened when exhausting, the sensor is placed incorrectly, the sensor is damaged, the drip pot is unstable, there is swing, the drip pot has water mist, and the drip pot liquid level too high.
Treatment method: replace the new infusion, open the flow regulator, open the exhaust cap, place it correctly, clamp the sensor to the drip pot, replace the sensor, fix the infusion pot, keep it stable, shake the drip pot, remove the water mist, and the liquid level in the drip pot Do not exceed 1/2 of the height of the dripping pot, place the infusion bottle upright, and then squeeze part of the liquid back into the bottle to lower the liquid level; keep the opening rate.
4. Pressure, blocking alarm
Cause of failure: The flow rate regulator (screw clamp) is not loosened, the infusion tube is broken or compressed; blood clots obstruct the venous access, and the proximal blood vessel pressure is too large.
Treatment method: Loosen the flow rate regulator (screw clamp), release the discount or pressure of the infusion tube, remove blood clots, loosen the tourniquet, wear clothes with wide cuffs, and avoid measuring blood pressure on the side of the infusion limb.
Analysis of common problems
1. Infusion volume input error
In the process of clinical use, the infusion pump is prone to the problem that the set input volume does not match the actual input volume.
Influencing factors :
#Some nurses did not take out the medicines left in the last infusion process when using the infusion pump, which resulted in the accumulation of too much liquid medicine, which would cause the infusion pump to alarm.
# The infusion pump and the infusion pump tube are not matched with each other, resulting in the pump tube diameter and tube wall elasticity not meeting the standard, which will make the setting of the input volume wrong, making the required infusion time under the same infusion speed different, affecting the infusion The normal effect of the pump is exerted.
#When the infusion pump is set, the input speed and the input liquid volume are reversed, which causes the infusion pump to fail to work as expected.
Countermeasures: The operator needs to correct the working attitude, carefully check the relevant work, and avoid mistakes.
2. The infusion pipeline is blocked
The blood of some patients is in a hypercoagulable state, which will cause the infusion pump to pump the drug slowly, or even block the infusion pump when the needle tip blood coagulates. In clinical application, the blockage of the infusion pump pipeline should be avoided.
The sound of the infusion pump alarm is sharp and ear-piercing, which will disturb the patient's rest. Even when the infusion pump is abnormal, the irregular alarm will be issued, which will greatly affect the patient's rest and even disturb the order of the hospital.
Compared with the traditional gravity infusion method, the infusion pump can reduce the workload of medical staff and improve the effect of infusion quality. However, the infusion pump is prone to problems such as irregular alarms and blockage of the infusion tube during use. Nursing staff should pay attention to the maintenance and management of the infusion pump, observe the infusion channel, install the infusion pump as required, and regularly repair and maintain the corresponding problems. etc., to ensure the safe use of the infusion pump and better play the positive role of the infusion pump.
