Pros & Cons: Kangaroo Joey vs. Zevex Enteralite Infinity

For about 4 1/2 months, we used the Kangaroo Joey feeding pump by Kendall. There were a lot of things we liked about it and a few things we didn't like. When Raya got more mobile, it became necessary to switch to a more compact & mover-friendly pump, the Enteralite Infinity by Zevex. Here are the things we liked & didn't like about both pumps.

Kangaroo Joey

*Fairly easy to program
*Large well-lit screen
*IV pole clamp has a place to wind the cord around it
*The "Prime Pump" button primes the line really quickly
*The adaptor plugs (at the end of the pump bag tubing) stay plugged in to an NG tube better than the ones for the Infinity pump
*The alarm has a volume control that is easy to find
*There are still a couple hours of battery life after the low battery warning starts beeping :)
*Has several different language options
*The backpack we had for it had a flap with a see-through window that allowed access without having to open the backpack
*All of the programming is simple and user-friendly (Especially nice when home health doesn't provide you with an owner's manual.) *Owner's manual can be found by clicking here*
*It has colored lights that show when it's running or not running (easier to tell at a glance when it's running than the Infinity)

*Not suitable for a baby/child that is mobile
*Has to be kept upright or else air will get into the line
*Buttons are easy to push (Ask my 2 year old, she changed the language to Dutch once and turned off the pump without anybody noticing for about 6 hours.)
*It's noisy in comparison to the Infinity (makes more noise while it's running)
*It's bulkier and heavier than the Infinity

Zevex Enteralite Infinity
*Very small & compact
*Can be used in a backpack that's small enough for a crawling baby to wear
*Easy to program
*Can be turned any direction without disrupting the feed
*Can be primed without using the "prime" button
*Pump sets load very easily
*Has one alarm tone to signal the end of a feed and a different alarm to signal a problem with the pump [**NOTE: We've had to exchange our Zevex pump a couple of times for different reasons and the new ones have not had an end-of-feed alarm, which can be bad if you forget to reset the dose before starting an overnight feed. Not that we've ever done that.**] **See update below**
*MUCH quieter-running than the Kangaroo Joey
*Adaptor plugs are made to plug more securely into a G tube extension set than Kangaroo Joey adaptor plugs
*We haven't had as many problems with broken pump sets with the Zevex Infinity pump as we did with the Kangaroo Joey pump

*The "prime" button is SLOWWWWWW
*The adaptor plugs on the pump bags don't work as well with NG tube ports as the ones for the Kangaroo Joey pump do
*The tubes can get kinked easily when being used with the little backpack because of where they enter & exit the pump in relation to the pocket/zipper on the backpack. We never zip the front pocket all the way.
*IV pole clamp doesn't have anywhere to coil & store power cord
*Screen is small & difficult to read from an angle
*Alarms & volume can't be changed**See update below**
*Because the backpack Raya uses is so small, it's a little more difficult for an adult to carry (i.e. strap doesn't fit on my shoulder)
*It's really difficult to plug in the pump to charge it without taking it out of the backpack, unlike Kangaroo Joey
*The cover for the pump set (where you load the pump set into the pump) is on the front of the pump which makes it hard to keep it protected. (a cracked cover was the reason we had to exchange the first pump)
*The caps on the pump bags are made to detach from the bag (instead of being tethered to it) and if they accidentally pop off once, they'll never go back on to stay **Update: The company that makes the Zevex Infinity pump has re-designed the pump set and changed the way that the caps attach to the bag so it's not as much of a problem, however, the new design is more difficult to hang in the backpack than the old one and we're not huge fans of some of the changes.**
*Starts beeping if the pump is on for more than 2 minutes without pushing the "Run/Pause" button which is annoying
**UPDATE 2-11: It was brought to my attention that it IS actually possible to change the volume of the alarms on the Zevex Infinity pump and to turn on/off the end of dose alarm. (Thank you, Sandy!) However, I have to say that there is no way in heck I would have ever figured it out without the user's manual (click here for manual) because who would ever think to push the on/off button while holding down the + button at the same time for 1.5 seconds in order to adjust the alarms and then use the Prime button to scroll through the options. Seriously?!? NOT very user-friendly, especially for people whose home health company doesn't provide a user's manual or mention that it's available online (thank you again, Sandy, for the link!).

Apparently I don't have many pictures of the Infinity pump yet. :)
I loved the Kangaroo Joey pump. There are a lot of things that I miss about it and certain features of the Joey pump that I preferred over the same features on the Infinity pump. That being said, there came a point when the Joey was just not working for us anymore because Raya became too mobile for it. If she moved too far from the backpack, it tipped over and air got into the line so I'd have to pause the feed to reprime it. The Infinity pump is a must for a mobile child, but is not a great combo with NG tubes. The adaptor plugs don't plug into the ports on NG tubes as far as the plugs on the Joey pump bags do, which makes it easier for them to come unplugged. They do plug nice & securely into the G tube extension tubes though.

Conclusion: Kangaroo Joey pump is great for NG tubes and those with limited mobility, Enteralite Infinity pump is great for G tubes and babies/kids on the move.

  1. Thanks for this great list of pros and cons with the two pumps. A couple of things regarding the EnteraLite:

    You say "Alarms & volume can't be changed." See page 26, manual page 19 for instructions on changing the alarm volume.

    You also say "...the new ones have NOT had an end-of-feed alarm..." This alarm is one that can be turned on/off. See page 26, manual page 19 for instructions on changing this setting from "MUTE WHEN DONE" to "BEEP WHEN DONE."

    If your pump remains backlit when it's plugged in and this is bothersome, there are also instructions for turning off that setting.

    Our home care agency provided select pages of the instruction manual to us and I had to look up online how to make these changes, but they do certainly make the pump a little less frustrating.

    Good luck!

  2. Glad to help. I found your blog when searching for the pros and cons of both pumps for our little guy. Ultimately, we're making the same decision, to go with the EnteraLite, even though I find the Joey more user-friendly.

  3. awesome list! thank you. we have a zevex now that we have to give back as our insurance is switching which mail order place handles our Rx's and the new place wants us to have a pump from them and they offered the joey but will give the same zevex if i want. i think we will be sticking with what we have thanks for the whole run down!

  4. This is SO HELPFUL!! Thank you so very much for sharing.

  5. I cannot tell you how much you have helped me!!! I was struggling with things that I assumed were just part of this....I didn't know that we could go mobile...we have a Kangaroo Joey and I have been struggling to tie him down for his MANY feeds. I just got off the phone with our medical supplier and they are ordering him a backpack. Thank you for helping me know what to ask. I have also ordered supplies for keeping his tube in place (which has been another struggle that I didn't know had a solution). I guess I am so clueless to this new world we have just found ourselves in....thank you for sharing your wisdom and experience!!!

Sensory Processing Disorder: How to Make a Weighted Blanket

Lately I've been toying with the idea of making Raya a weighted blanket. She loves heavy things and has a lot of sensory seeking behaviors in regards to proprioception. Translation: she craves sensory input that helps her to gain awareness of where her body is in space, and it takes stronger than average input for her to get the feedback that her body is craving. (or at least that's how I understand it :) She seeks out "heavy work" activities, like carrying heavy things, pushing heavy things around on the floor (chairs, full laundry baskets, etc), and anything that gives heavy resistance to her muscles and joints. Lucky for us, carrying her backpack is a good heavy work activity because the poor kid gets to do that for a few hours a day. :)
The idea behind a weighted blanket and other heavy work activities is that when the child gains greater body awareness through proprioceptive input, the nervous system can be calmed and the need for constant fidgiting, moving, jump…

Adhesives Part 1: Adhesives & Taping Techniques for NG tubes

This series has been a long time in the making. Back when Raya got her NG tube, I had no idea there were so many different adhesives on the market. At the hospital, they had used some kind of fabric tape in a box that had to be cut with scissors and that was the ONLY thing we accidentally left at the hospital. Raya caught her little pinky finger on the tube a couple days after we got home and the only medical tape I had ended up bringing home was Durapore. This tape is VERY sticky, very strong, and definitely not the best option for the tender little cheek of a 2 month old baby. A couple days later, we went to the GI doctor and the nurse saw the tape and told me that Duoderm would be much gentler on her skin and she gave me a couple of 6x6 sheets to try out.
That was the beginning of our trial-and-error process of figuring out which types of adhesives were better for all of the different things we used them for. This will of course NOT be an exhaustive review of every adhesive out the…

Feeding Tube Terminology: G tube words

One of the many things I didn't have a clue about before Raya got her G tube was the fact that there are LOTS of different kinds of G tubes, all with similar but different features & functions. Some of the terminology that was tossed around in the beginning was very confusing. When I met with the surgeon to pick out a button for when Raya's initial tube was ready to be changed, they pulled a bunch of tubes out of a cupboard, put them down on the table in front of me and said, "What kind do you want?" I had NO idea what to pick, all I knew was that anything would be better than what we had at that point.

Here are a few things I wish someone could have explained to me before Raya got a G tube:

1. What the heck does PEG mean?
PEG stands for percutaneous endoscopic gastrostomy. In other words, a gastrostomy tube is placed through the abdominal wall using an endoscope to visually guide the surgeon to the best location to place the tube. The term PEG is used to refer to …
