You will need to rinse the foley catheter (double lumen catheter) periodically to remove contaminants and prevent blockage of the catheter. Rinse the catheter carefully using sterile equipment and normal saline or 0.9% NaCl.
Part 1 of 2: Preparing the Rinsing Solution
Step 1. Wash your hands
Use soap and water to wash your hands thoroughly for 15 seconds. If so, dry with a clean paper towel.
- If needed, an alcohol hand sanitizer or an alcohol swab can be used instead of soap and water.
- You should also clean the surface of the work area to be used with a disinfectant spray or alcohol swab. Allow the surface area to dry on its own before use.
Step 2. Clean the top of the copy bottle
Remove the protective plastic covering the saline solution bottle and wipe the clean top of the bottle with an alcohol swab.
- Rub the end of this rubber for at least 15 seconds. The goal is to make this part as clean as possible before use.
- When preparing a saline solution bottle, you should only touch the outside of the bottle. Do not let your fingers touch the top or the inside of the bottle.
Step 3. Attach the needle to the syringe
Turn the sterile needle into the sterile syringe, tightening it as tightly as possible.
- Use only syringes for sterile, unopened catheters. If you want to use clean needles and syringes that have been used before, you must get approval from your doctor.
- Make sure the needle remains protected by the cap when you attach it to the syringe.
- Also make sure that the needles and syringes remain sterile. Do not let the tip of the needle, the base of the needle, or the tip of the syringe come into contact with your skin or other objects.
- If you are using a needle and syringe that is already attached, make sure the needle is securely attached to the syringe by rotating it. A well-fitted needle will not move out of place.
Step 4. Fill the syringe with air
Hold the syringe in one hand while pulling the pump or suction down with the other. Pull on the suction until you have filled 10 ml of air into the syringe.
- Note that the black line on the suction tip should be exactly on the line next to the "10 ml" mark on the syringe.
- Generally, you will need to fill in 10 ml of air. Your doctor may order different amounts, depending on your need or condition.
Step 5. Put the air into the vial of saline solution
Insert the needle into the rubber end of the saline solution vial. Push on the suction and introduce the air in the syringe into the vial.
You should insert the needle into the vial perpendicularly and keep the syringe in a vertical position
Step 6. Take the saline solution into the syringe
Turn the bottle upside down, then pull out the sucker. Continue to pull the suction until the syringe is filled with 10 ml of saline.
- Keep the needle in the rubber tip of the saline solution bottle. Do not unplug and reinsert it.
- As you work, the needle should stay below the level (level) of the liquid in the bottle. Don't let the needle come into contact with the air in the bottle.
- As before, the black line of the suction tip rubber should be on the line next to the "10 ml" mark.
- If your doctor instructs you to use more or less saline, follow your doctor's instructions.
Step 7. Remove air bubbles
Tap on the syringe to remove any air bubbles, then push the trapped air back into the vial by gently pushing on the suction.
- Keep the needle in the bottle as you do this step.
- When checking for air bubbles, you should hold the syringe vertically with the needle up. Tap the syringe tube with your knuckle to remove trapped air. The air bubble will be lifted to the tip of the syringe, near the base of the needle.
- Once all the air bubbles have collected under the base of the needle, you can push the suction of the syringe in. Keep pushing until all the air is back into the bottle.
- If necessary, reinsert the tip of the needle into the saline solution and withdraw the suction again to fill a sufficient amount of saline into the syringe.
Step 8. Set aside the needle
Remove the needle from the saline bottle and attach the cap. Put it first until the needle is ready to use.
- If the needle does not come with a cap, put the needle back in its sterile packaging. The needle must not touch a non-sterile surface.
- Work carefully and make sure you don't get pins when you put the cover on.
Part 2 of 2: Rinsing the Catheter
Step 1. Clean your hands
Wash your hands with soap and warm water, rubbing them together for at least 15 seconds. If so, dry with a clean paper towel.
You should wash your hands again if you have just prepared the syringe
Step 2. Clean the catheter
Rub the location of the connection between the catheter and the drainage tube with an alcohol swab, cleaning the area for 15 to 30 seconds before moving on to the next process.
Let the area dry on its own. Don't try to towel dry and don't try to speed up the drying process by blowing the area with a breather or fan
Step 3. Prepare the area
Place several towels under the connection site that connects the catheter to the drainage tube. Place the basin under the open end of the catheter connection.
This basin will collect urine and other fluids from the catheter as you rinse
Step 4. Remove the catheter from the drainage tube
Gently twist the catheter from the drainage tube to release both.
- Immediately cover the end of the tube with a sterile plug cap to keep it clean. Set this drainage hose aside for a while.
- Position the catheter over the prepared basin. Do not allow the exposed tip of the catheter to touch the basin.
Step 5. Insert the empty syringe into the catheter
Attach an empty, sterile syringe to the open end of the catheter. Pull on the syringe suction to check urine.
- If no urine comes out of the catheter, you can proceed to the next step.
- If there is urine that comes out, use the syringe to remove (remaining) urine that is still in the catheter. Clean the catheter as thoroughly as possible.
Step 6. Replace the empty syringe with a syringe filled with saline
Remove the empty syringe from the catheter and insert the syringe containing the saline solution.
- If the needle is still in the syringe, remove it first before connecting the tip of the syringe to the catheter.
- Make sure you don't touch the tip of the syringe.
- Rotate the syringe to the base of the catheter until they are securely locked.
Step 7. Push the saline solution into the catheter
Gently, pushing the syringe suction, insert the saline solution into the catheter. Work carefully and stop immediately when you see any signs of resistance.
- In general, the "push-pause" approach is the best method to use. Encourage the suction to introduce 2 ml of saline into the catheter, then pause for a few seconds. Push another 2 ml into the catheter, then pause again. Repeat this pattern until all of the saline solution is inserted into the catheter.
- Do not force the saline solution into the catheter. If you notice any resistance, it is better to contact a nurse or doctor for help. The nurse or doctor may use other techniques to flush the catheter. The catheter may also need to be replaced.
Step 8. Remove the syringe
Pinch the tip of the catheter with your finger while removing the syringe from the base of the catheter.
If there is a clamp (clamp) on the catheter, close the clamp after removing the syringe
Step 9. Let the liquid drain
Let the force of gravity drain the remaining urine and saline solution into the basin that has been prepared.
You may need to hold the open end of the catheter over the basin for a few minutes to make sure all the fluid is draining
Step 10. Clean and tidy up
Clean the connection site and attach the drainage tube to the catheter again. Wash your hands after that.
- Use an alcohol swab to clean the area where the syringe and catheter meet. Let the area dry on its own.
- Remove the drain hose cover and rub the end of the hose with another rubbing alcohol. Let this part dry on its own too.
- Insert the tube back into the catheter. Check after 10 to 15 minutes to make sure that urine is flowing out of the catheter properly.
- Dispose of all used needles and syringes in a special puncture-resistant trash can.
- Wash your hands thoroughly with soap and warm water. Dry with paper towels when done.
- Once everything is clean and plugged back in, the process is complete.
