Once again, where can I get peristaltic tubing?

[Vincerama2]

Ugh, I know I've asked this question 20 times already, but since the RC search function is basically non-functional, I have to ask it again...

My peristaltic tubing is once again worn out. I did have a few "enteral feed pump sets" but I've run out. It makes more sense to just buy a length of enteral tubing and then never ask again.

So....where in the Bay Area (or online...it's hard to find retailers versus manufacturers with a google search) can I get some? I think I need 1/4" tubing.

Thanks! (again)

Try this next time you need to search.

And we get out son's feeding equipment from the "Children's Home Pharmacy at Stanford (650) 497-8316 although our son doesn't use a feeding pump, this is what they do so I'm sure they'll have some.

I will check with some friends who do use feeding pumps and post back for cheaper solutions.

Sweet, thanks for the search link!

I found some tubing on the USPlastics site, which actually sells to the public. (It was hard filtering out the sites that just show their products, but as manufacturers).

It looks like Cole Parmer may sell to the public: http://www.coleparmer.com/index.asp

The C-Flex tubing is more wear resistant, and less gas permeable. It's expensive, though.

Cole Parmer, McMaster Carr, USplastics, and just about any scientific place will have it in stock. We buy it by the case and have it the next day.

What tubing size do you need? How Long? What Type?

us plastics or bluebook usa

I'm not sure! It's the tubing that comes with "feeding pumps", so I'll measure it at home, but it looks like airline tubing. Got some?

I'd say 2 feet would last me a looong time. For a while I was modding the feed bag things, until I figured out I could just steal the peristaltic tube from the bag and replace the busted piece in my hacked together pumping system!

I'll measure the piece I have at work. I can't see the leak in it, but it's pumping bubbles.

What is your dosing rate and what kind of pump. I will see if I have a tubing size that works. It is expensive to buy online as very few places sell 2 feet. Most sell like 20 feet +.

 

[Vincerama2]

I'm using a "Compat Enteral Feeding pump" Generally I run it at 100 ml/hr.

I'm holding the piece in my hand now..

Using a ruler, I'd say it has an outer diameter of about 3/16" and the wall is about mmm.... less than 1/32" ??

That isn't really a peralistic pump. That is a medical doser. Can't help you with that one. Your going to just keep buying hoses for that guy as it works by stretching the hose. Or get a real peralistic pump.

Good Luck.

 

[Vincerama2]

Hmmm. This thing has the 3 sided roller thing that strokes the tubing...isn't that peristaltic?

Thanks anyway. I'll try the US plastics site and tell you how it works out!

Vince - have you thought about using quick disconnects in your tubing? That way, when the tubing in the rollers wears out, you can just disconnect that part of the tubing and you have less tubing to replace. You could then also use stronger tubing in the roller section without having to spend a fortune on a ton of it.

 

[Vincerama2]

Actually, I only need to replace the small piece at the rollers. The feeding sets only have a section that is lik 5 inches of peristaltic tubing, the rest is sort of airline tubing like. And those connect to the peristaltic tubing with connectors that are fairly easy to remove the peri-tubing from.

I'm just going to guess at the right size and order some! my options are otherwise limited to buying more entire sets, and it's about time I tried to find out which size will fit.

The rollers is what makes the pump a "peristaltic" pump. Many "medical dosing pumps" are peristaltic pumps. check out the link above....

There aren't rollers on a dosing pump, there is a wheel that stretches the tubing. Take a look at a peralistic pump. You will see the difference.

 

[PiNaPLeX]

ok, is it just me or does the Compat Enternal Feeding Pump look like it works alot like this peristaltic pump and these other peristaltic pumps ?? I'm just trying to figure out what the difference is between the socalled "medical doser" that vincerama has, and these other "peristaltic pumps".

 

[Vincerama2]

yes, the Compat Enteral Feeding Pump is similar to the ones in your second link. In fact, the ones in the second link ARE medical dosing pumps!

My pump;
1) Uses "Feed bag sets" which are those IV drip type bags, which you would fill with liquid food for patients. The "feed sets" have a piece of peristaltic tubing in the line, which fits into the doser.
2) the dosing mechanism IS PERISTALTIC. There are 3 rollers that "stroke" the peristaltic tubing and administer the food to the patient
3) It has a battery backup, because you don't want patients to starve if the power goes out
4) It has ALARMS which go off and shut down the pump if the bag is empty OR liquid is "free flowing". This is, of course, to protect the patient
5) You can adjust the dosing rate from 1 to 295 ml/hour.

The pumps in your second link are modified so that the alarms don't go off (I think). Another issue with my pump is that you can't just plug it in and unplug it to make it work. You have to plug it in, press the ON button, then press the RUN button. This means you can't just hook it up to a float valve and control the flow by switching power to the pump. Some simpler peristaltic pumps do that and might be better for dosing if you use a float valve.

The only complaint I have about mine is that I haven't found a good replacement peristaltic tubing source (YET), and I've been buying the feed sets and taking the tubing from them, but each feed set is like $5. (though they last for like 4-6 months). Not a problem really, if I could find them locally in a medical supply place, but I haven't found a place (not really looking that hard) that sells the feed bags (I bought some off eBay that I've been using for the past 2 years, but I've run out now).

I'm going to try some of the tubing sold by US Plastics and see if it works. I'm sure it will mess up the ml/hr settings, but that's not important, since I'm feeding my kalk mixer, not a person!
