Infinity Pump

If you are unable to meet your nutritional needs by mouth, a feeding tube provides a way to obtain life-saving nutrients. Your doctor may have prescribed this method of feeding to deliver formula and water into your stomach by way of your feeding tube. The Enteralite Infinity pump is a feeding pump made by Moog.

With the pump feeding method, formula is infused into your feeding tube with an electric/battery-powered pump. For some, this slow, metered infusion of formula may be better-tolerated than bolus or gravity methods.

Enteralite Infinity Pump

The Enteralite Infinity enteral feeding pump is light, portable and easy to use. It fits inside an enteral backpack with ease, so that you can go about your daily activities and still get the nutrition your body needs to stay active.

Supplies:

  • 60 milliliter catheter tip syringe
  • Room-temperature water
  • Feeding bag
  • Feeding Pump
  • IV pole or Backpack
  • Formula

Instructions:

  1. Wash your hands to reduce the risk of bacterial contamination.
  2. Get your supplies together: formula, 60 milliliter catheter tip syringe, room-temperature water, feeding bags, feeding pump and IV pole or enteral backpack (a pack designed to hold your feeding bag so you can feed on-the-go).
  3. Check the skin around your feeding tube. If you notice redness, pain, irritation or leaking around the site, notify your doctor or nurse.
  4. You should be sitting upright for your feeding and for 30 to 60 minutes afterward.
  5. Check the position of your feeding tube. You should have about the width of a dime between your skin and the external bolster. In most cases, the tube should turn freely.
  6. Place the tip of the syringe in the water and pull back on the plunger to draw up 30 to 60 milliliters of water (or the amount advised by your healthcare professional).
  7. If you have a low profile feeding tube, attach the extension tubing.
  8. Open your feeding port and flush the tube by slowly pushing on the syringe’s plunger. Flushing your tube before and after feedings helps to clear out any formula or medication residual to prevent clogging of your tube. Flush the tube every time you use it for feeding or medications or every time you turn the pump on and off.
  9. Hang the feeding bag from the IV pole so that the bag is at least 18 inches above you. If you have an enteral backpack, secure the bag inside and thread the tubing through the holes and out the back of the backpack.
  10. Insert the cassette into the feeding pump. The cassette is the blue loop part of the tubing connected to the feeding bag. The loop wraps around the rotor to push the formula through the tubing and into your body. Close the pump door and turn the pump on. Keep it plugged in if you are near an electrical outlet to keep the pump charged.
  11. Open the bag and pour in the desired amount of formula.
  12. Remove the cover on the tip of the feeding bag’s tubing. Position the tip of the tubing over a receptacle to catch any formula that drips out.
  13. Prime the tubing to release any air. This will prevent the air from going into your body and making you uncomfortable. You can do this manually or with the automatic prime feature of the pump. Manual priming may be faster.
    • To prime the tubing manually, squeeze any air out of the bag and close it. Remove the cassette from the pump. Look for a raised tear-drop etched onto the blue part of the tubing. Gently press the tubing together with your thumb and index finger to allow the formula to free-flow through the tubing until it reaches the tip. Re-insert the cassette into the pump and close the door.
    • To prime the pump using the prime feature, push and hold the prime button until the formula reaches the end of the tubing. Release the prime button.
  14. Attach the tip of the bag’s tubing to your feeding tube or extension tubing.
  15. Set the rate of the pump by pressing the “rate/dose” button until the word “RATE” is displayed on the screen. Push the “+” button until the desired rate is reached.
  16. Set the dose you want to deliver by pressing the “rate/dose” button until the word “DOSE” is displayed on the screen. If you want to set a specific amount, push the “+” button until the desired amount is reached. If you want the pump to simply shut off when the formula is gone, continue to push the “+” button until the “INF” (Infinity) is displayed on the screen.
  17. If you experience any symptoms of feeding intolerance, such as nausea or vomiting, diarrhea or abdominal bloating, contact your healthcare professional.
  18. When you are done feeding, disconnect the bag tubing from your feeding tube.
  19. Flush your feeding tube with water as above with the amount recommended by your healthcare professional.
  20. Close the feeding port and disconnect the extension tubing if applicable.
  21. Refrigerate any leftover formula for use within 24 hours.
  22. Wash and dry all equipment and your hands. Use a new syringe and feeding bag each day.

    Cost
    Where can I purchase
    Will insurance cover ( Medicare)

    Hi Ed,
    Thank you for your question! Medicare will cover the pump and related supplies for beneficiaries in certain instances when medically necessary. Check with your medical supply provider to see if they are contracted with Medicare to provide enteral supplies in your area. You may also be able to purchase the pump through a medical supply provider with a prescription from your doctor. If you don’t yet have a provider I think you can find one through your insurance plan.

    Hi Barbara, thank you for your question! You can obtain the feeding pump from your medical supply provider. If you don’t have a medical supply provider, you may be able to find one through your insurance plan.

    Is there an auto prime feature, where you do not have to hold down the prime button to prime tubing?

  6. Posted September 26, 2016 at 9:51 am PDT

    Hi Alfred, this pump does not have an auto prime feature. You will need to hold down the prime button until the bag and tubing are primed. A faster option is to prime manually. Squeeze the air out of the bag and close it. While holding the bag, use your fingertips to gently squeeze the spot right next to the etched tear drop on the blue tubing. This allows formula to “Free-flow” out down the tubing. When the bag and tubing are primed, you can release the blue tubing from your fingertips. These instructions are also in the operators manual for the pump (see page 8): http://www.infinityfeedingpump.com/pdf/operators-manual-eng-fr.pdf. I hope this helps!

    How do I make the flow slower on the pump? It’s supposed to run for eight hours and three hours before time is up the formula runs out I’m a doing something wrong???

  8. Posted August 9, 2017 at 9:25 am PDT

    Hi Janet, there may be some margin of error but it shouldn’t be that much! Let’s check your calculation. Take the volume of formula that you want to infuse and divide it by the number of hours you want it to run for. For example, to run 1200 ml for 8 hrs: 1200 ml divided by 8 hrs = 150 ml/hr.
