Quick Overview

Freedom Flow™ II is the perfect solution for independence during your private moments.

Freedom Flow-II, is a new wireless Leg Bag Emptier which opens and closes the urine bag with the push of a wireless button using new high-tech Flexinol™ which is a dynamic alloy wire that changes length when a voltage is applied to it.  This creates a very powerful, reliable valve with no moving parts that stays shut naturally.

Freedom Flow pinches the tubing that comes with your leg bag, meaning it is always external and year and never touches the equipment.  You can follow your normal routine or replacement of your leg bag keeping everything clean and odor free.  Pushing the wireless button causes it to release its firm pinch grasp on your leg bags latex tubing, allowing it to drain rapidly, approximately 10 times faster than mechanical valves used through the 80s and 90s.

The rechargeable batteries last approximately 1 week. Since it does not depend on power wheelchair batteries it can be used with a manual chair or a power chair or scooter or any other mobility device.

Our clients, the quadrapeligic community love the independence this device brings to them.

No wires, bulky batteries, washers or screws! Just a small valve and wireless push-button installed in 2 minutes! Urine will never touch your device.

In the late 1980’s Dr Behrokh Khoshnevis, a distinguished professor at University of Southern 
California, developed Freedom Flow, the wired leg bag emptier. He invented this device to help a friend who was injured during a sport activity.

Freedom Flow was serving the paraplegic community for several years; its only problem was the 
wire that connected the push button to the valve. This wire was getting tangled in the wheelchair and it was inconvenient during transfer from one wheelchair to another. This problem encouraged the development of Freedom Flow.

Dr. Mohammad Fatehi, a Bell Labs and Booz Allen Hamilton scientist, brought the wireless Freedom Flow to life. This advancement gave a lot more flexibility to Freedom Flow. Now Freedom Flow-II, the wireless leg bag emptier, is on the market.  Professionals love the ease of use and installation.  End-users appreciate odor free reliability without tangles.

Note about Latex Tubing Selection

You must use the correct rubber tubing attached to the Bottom of your leg bag for Freedom Flow to operate correctly. Soft yellow-brown latex tubing (oxygen tubing, drainage tubing), with inside diameter of ¼" is readily available at pharmacies, laboratory equipment suppliers, is required to work with Freedom Flow. Freedom Flow slides onto this tube and will clamp it shut. When activated, Freedom Flow will open to allow urine to drain. It will then re-clamp the tube.

Frequently Asked Questions

Although the Freedom Flow™ II is the simplest leg bag emptier on the market, we know everyone has questions. If you don't see the answer to your question below, feel free to contact us!

Is there a warranty

Yes! We are committed to replacing your Freedom Flow™ II if there are any workmanship defects for 1 year from the date of purchase. Any problems arising due to misuse, attempt at repair, dropping, contact with water or extreme wear are not covered by this warranty. 

Is the Freedom Flow™ II covered through insurance?

Bear with us on this one. We are currently working to get the Freedom Flow™ II covered by insurance, but as you can imagine, it's a process. Don't worry, everyone will be updated when the process is complete!

Is there a possibility that the remote shares a frequency with another electronic item?

The chances of the Freedom Flow™ II remote being powered by another electronic frequency other than it's own is highly unlikely. The odds are about 17,000,000 to 1. Let's just say, we have been doing this for over a decade and it hasn't happened yet. 

Do I have to strap the unit onto my ankle?

While it is recommended to strap the unit onto your ankle, you have the freedom to attach it anywhere that is comfortable for you. Some other options would be attaching it to the side of the wheelchair or using a piece of adhesive Velcro® to stick the unit directly onto the leg bag. 

How big is the device?

The Freedom Flow™ II main unit is 3.5" x 1.5"x 1.5". 

Does the device require maintenance?

No, the unit should not come in contact with any bodily fluids and therefore does not need to be cleaned regularly. If desired, you can take a damp cloth to the device, but do not submerge it in water. The Freedom Flow™ II should last for many years with no trouble!

Is it difficult to press the button if I have limited finger mobility?

The button is an "easy-press" button that requires low force. We specifically chose this button, compared to a "toggle switch", which is often more difficult to use. 

You also do not have to hold the button down to empty the entire bag all at once. Instead, you can open the valve multiple times (as many as you need to) to empty the bag at your own pace. A 1000mL urinary leg bag empties in about 15 seconds with the Freedom Flow™ II. 



Where you go, we go! The Freedom Flow™ II is all about giving back independence to those with limited mobility, so we love when pwhen you are mostlyeople put our name out there! Below are some places that the Freedom Flow™ II is mentioned. 

The video below shows exactly how this leg bag emptier works, you can see that two flat plates come together and trap the tube to stop any fluid escaping, as soon as you press the button the two plates move apart letting the fluid flow freely.  You can also see that there is a button on the bag opener, this enables you to open the two plates in order to pull the tube through.

"I love my Freedom Flow™ and it works great! It gives people like me great independence and freedom!"     -Anonymous

I have been using an electric leg bag emptier since the early 90s.  The first one I got was from a family run business here in the UK.  Unfortunately they had a tendency to leak which is obviously not  nice.  Around 1995 I came across another company who were selling a different type of electric leg bag emptier.  This one was a lot more reliable and I had hardly any problems with leakages.  However, the design was not very good in my opinion.  Because these bag emptiers needed to run off the 12 V supply, they obviously needed to have some kind of wires attached to the emptier.  The RD Equipment leg bag emptier had two very flimsy spade end terminals attached to the emptier.  In my opinion this is a flawed design because it didn't take much to break these terminals.  Once they were brokenly off there was nothing to attach the wires to, you literally had to solder the wires onto the outer body which both difficult and very crude.  To be perfectly honest, anything that is wired into a wheelchair is going to break occasionally.  I have lost count of the times the wires have broken over the years, there's nothing worse than finding that your bag opener doesn't work after all your carers have left for the day.

I have just purchased a brand-new Permobil electric wheelchair and I really didn't relish having to get somebody to wire my leg bag emptier into the chair again.  So I had a look around on the Internet on some of the forums and somebody on the CareCure spinal injury support forum recommended the Freedom Flow Wireless leg bag emptier.  They have got various YouTube videos showing how these leg bag emptiers work so it was easy to see how good they seem.  So I have bought one and have now been using it for the last few days.

Freedom-flow-leg-bag-emptierThe Freedom Flow leg bag emptier works in a completely different way to the two other leg bag emptiers I've had before.  For starters it is completely wireless, it doesn't rely on any wiring and you don't have to wire it into your wheelchair batteries, or have to have any type of battery hanging off the back of your wheelchair.  Rather than using a valve, the Freedom Flow uses an electrical function which pinches a tube together as you can see in the video at the bottom. When you activate it using a wireless control box, the pinched tube is released letting fluid flow.   The valve type emptiers would often leak, this would result in me having to get somebody to take it apart and clean the valve out properly.  This cannot happen with the Freedom Flow because it doesn't use a valve, fluid just flows from your bag  straight down a rubber tube, there is nothing to get restricted or clogged up.   Cleaning the Freedom Flow is simplicity itself, there is no need to take the chair into the bathroom and run a bag full of water and disinfectant through the opener, all you need to do is clean the tube, takes a minute.

I have opted to attach the leg bag emptier to my leg in a different way to what they suggest.  They suggest that you Velcro the leg bag emptier to your leg bag, I'm not sure that this is really a good idea since most of us change our leg bags every day.  Therefore I have opted to use the Velcro straps that come with my leg bags, using two of them I have strapped the leg bag to the inside of my ankle as you can see from the picture to the left will stop

I have made a video which shows the basic operation.  My bag was almost full, probably containing between 700 and 750 mL of fluid at the time.   I have not been using this bag opener for that long, however so far I am extremely impressed.  The only thing that you will have to remember is to charge it at least once a week, obviously depending on how many times a day you empty your bag.
