How To Use Infusion Pump Correctly？

Introduction

Infusion pump is mainly used to accurately control the amount and speed of liquid infusion per unit time, and by controlling the volume of liquid infused per unit time, the purpose of making the drug speed uniform, the dosage accurate and safe injection into the patient's body can be achieved.

It consists of 5 parts: microcomputer system, pump device, detection device, alarm device and input and display device.

Basic operation: 5 processes are completed, including placing the infusion pump securely, fixing the infusion pump tube in the infusion pump pipeline groove, setting the parameters of the infusion pump, performing venous puncture and infusion.

Working principle

The peristaltic row continuously squeezes the infusion tube filled with liquid in a wavy manner, pushing the liquid in the tube to flow downward. The faster the conveyor drives, the more liquid is squeezed out, and vice versa. Therefore, the flow rate of the infusion pump can be accurately controlled.

The infusion speed is not affected by the liquid level and the patient's body position changes, and ultra-low speed to high-speed infusion is completed.

Operation steps

1. Preparation of materials: check the doctor's order, prepare the medicine, select the infusion pump tube; check the function of the infusion pump.

2. Patient preparation: briefly explain to the patient the purpose of the infusion pump application, the importance of infusion volume and infusion speed; tell the nurse to deal with it in time when the infusion pump alarm sounds; do not move the infusion pump at will.

3. Environmental preparation, quiet, clean, comfortable, and in line with infusion requirements.

4. Personal preparation, wash hands, and wear a mask.

5. Turn on the power, open the pump door, and correctly install the hose part of the infusion pump tube into the slot.

6. Close the pump door, and then check whether there is gas in the infusion pump tube.

7. Clip the drop number monitoring sensor on the drip pot and fix it with a fixing bracket.

8. Press the switch key, and the instrument will self-check.

9. Use the number keys to set the infusion speed and the reserved infusion volume.

10. Perform venous puncture and start infusion.

11. Press the stop key to stop the infusion of liquid; turn off the flow rate regulator of the infusion pump tube; press the door lock, open the pump door, and remove the infusion pump tube from bottom to top; press the switch key to turn off the infusion pump.

12. Keep the pump body clean and wipe it with a slightly damp clean soft cloth; clean up the supplies and keep records.

Troubleshooting

Bubble alarm

Common causes of failure: Bubbles in the pipeline, the liquid in the solution bottle or bag is empty

Handling method: Open the door to remove the pump tube, discharge the bubbles, and replace the new one

Battery low voltage alarm

Common causes of failure: Insufficient battery/accumulator power, invalid battery charging

Handling method: Connect AC power supply and replace the same type of battery

Drop count alarm

Common 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 swinging, there is water mist in the drip pot, and the liquid level in the drip pot is too high

Handling method: Replace the new infusion, open the flow rate regulator, open the exhaust cap, place it correctly, clamp the sensor on the drip pot, replace the sensor, fix the infusion pot, keep it stable, shake the drip pot, remove the water mist, the liquid level in the drip pot cannot exceed 1/2 of the height of the drip pot , put the infusion bottle upright, and then squeeze some of the liquid back into the bottle to lower the liquid level

Maintain the opening rate

Common causes of failure: The liquid in the infusion bottle or bag is empty

Handling method: Replace the infusion or stop the infusion according to the doctor's advice

Pressure, blockage alarm

Common causes of failure: The flow rate regulator (screw clamp) is not loosened, the infusion tube is bent or compressed

Blood clots block the venous access, and the proximal blood vessel pressure is too high

Handling method: Loosen the flow rate regulator (screw clamp), remove the infusion tube from being bent or compressed, remove the blood clots, loosen the tourniquet, wear clothes with wide cuffs, and avoid measuring blood pressure on the infusion limb side

Precautions

Selection of infusion pump tube

1. It is recommended to use consumables that match the infusion pump, and the infusion pump tube should be used as required and replaced daily.

2. Select the infusion pump tube according to the properties of the infused liquid and drug, such as the light-proof infusion pump tube.

3. When the infusion rate is < 0.5m1/h, a special infusion pump tube with anti-backflow function must be selected to prevent blood from blocking the pipeline.

Installation method of infusion pump tube

1. First install the infusion pump tube into the groove on the side of the handle panel.

2. Press the stop clamp handle to install the pump tube into the groove and then release it.

3. Install the pump tube into the groove in the middle of the air sensor through the peristaltic extrusion groove.

4. Close the pump door and open the pump tube flow adjustment clamp.

How to change the infusion rate

1. Press the [Start/Stop] key to display the stop power.

2. Press the Clear/Confirm key. When the horizontal line below the infusion speed flashes, press up and down to adjust the infusion speed.

3. Press the [Start/Stop] key to restart the infusion and display that the infusion is in progress.

Safe use

1. Operate only after professional training and reading the instructions.

2. When using AC power, ensure safe grounding and keep the AC interface dry and clean. Ensure that the battery is fully charged to ensure that the infusion pump can operate normally in the event of AC power failure or during patient transfer.

3. The infusion tube in the pump door must be kept vertical.

4. During the infusion process, check the dripping speed regularly.

Rapid infusion - pay attention to observe the liquid leakage at the puncture site.

Slow infusion - pay attention to observe whether there is blood return or pipeline blockage.

Maintenance

Cleaning and disinfection

1. Wipe the infusion pump housing with a slightly damp clean soft cloth.

2. Clean the drip rate sensor with anhydrous ethanol.

3. Disinfect regularly to prevent cross infection, wipe the instrument with disinfectants such as 5% chlorhexidine, 2. 25% glutaraldehyde or 75% alcohol.

Daily management

1. Check the infusion pump once a week to test the performance of the infusion pump, flow, capacity and blockage pressure.

2. Avoid liquid from penetrating into the pump; when the infusion pump is not in use, store it in a cool and dry place to avoid severe vibration, direct sunlight or ultraviolet radiation.

3. Manage by a dedicated person, establish a usage registration, regular inspection, maintenance and repair system.

Maintenance

1. Before using for the first time, or when not in use for a long time, when using again, connect the infusion pump to the AC power supply to charge the built-in battery for at least 12 hours.

2. When not in use for a long time, the internal battery should be charged and discharged at least once a month; if the working time of the battery is shortened after charging, it should be replaced with a new battery in time; if the infusion pump fails, report it in time.
