Frequently Asked Questions

Q: How does the JB-3 work?

A:  The JB-3 uses a plunger to pinch a thin walled latex tube from the leg bag against a small stainless steel bar.  This means that there is no body fluid contact with the JB-3 so there is no corrosion of valves or accidental plugging by mucus from a developing bladder infection.

Q: The bar is stainless steel, but what else is the JB-3 made of?

A: All of the components of the JB-3 have been engineered to reduce weight, while increasing reliability and longevity.  The Pull Ring, Belt Loop, and "C" Bracket are made from the same plastic as bullet-proof windows.  The cable is an ultra-high strength polymer monofilament with low friction properties.  The clamp body and plunger are machined from a polymer with extremely low wear characteristics, low friction properties, and excellent dimensional stability.

Q: Will I have to modify my wheelchair to attach the JB-3?

A: No, the JB-3 only needs to be attached using the provided hook and loop strap around the arm of the chair or some other convenient place on the chair.

Q: What if I don't have any place that is convenient on the chair to attach the JB-3?

A: The JB-3 has been designed to easily slip on to a belt loop or the belt of trousers instead of using the Velcro(R) strap.

Q: How much strength do I need to have to activate the JB-3?

A: Less than 2 pounds of pull will activate the JB-3 enough to drain a 750 ml leg bag in less than 30 seconds. If you can lift a can of soda, you can empty your leg bag in under 30 seconds.

Q:  All the other valves I've seen require batteries.  Does yours?

A: No.  The JB-3 is completely mechanical.

Q: If it's completely mechanical then how can someone like me who is severely handicapped activate it?

A: The JB-3 has been developed from the very beginning with people that have high-level disabilities as its primary user.  Every element of the design has been evaluated and optimized by professional engineers to reduce friction and use the least amount of spring pressure over the smallest possible area to maximize the sealing effectiveness.

Q: How good is the reliability to prevent dripping?

A:  The JB-3 has a patented design that allows the user to modify the pressure of the plunger that pinches the exit hose from the leg bag.  The pressure can be increased to accommodate varying thickness of latex exit tubing or reduce the amount of pulling strength needed to activate the JB-3.  We've tested the JB-3 on a machine that pulled on the pull ring and retracted the plunger back 3/8 of an inch for over 25 thousand times and it still didn't fail.  If you were to use the JB-3 five times a day, that's over 5 thousand days, or over 13 years of use!

Q: Does this mean that I can use my existing latex hose with the JB-3?

A: Yes, the JB-3 was designed to accommodate all commercially available drain tubing.  We provide the thin-walled, black, latex tubing which has been optimized to reduce sealing pressure.  Therefore, the JB-3 can have the lowest possible pull forces to activate and also provide the most reliable seal that prevents leaks.  The adjustment mechanism of the JB-3 allows the user to increase sealing force if other types of tubing are used.  This generally results in an increase to the pull force required to activate the clamp by less than 1 lb.

Q: Is there any maintenance that needs to be done?

A: No.  The device may need to be cleaned if dirt gets into it, but there is no oiling or preventative maintenance required.

Q: I've tried other valves and have been disappointed, what makes yours superior?

A:  The JB-3 is the third generation of a device that we designed over 8 years ago.  The first two models (and countless prototypes) have been used successfully, and without failure, for over 8 years by a number of users.  By designing a completely mechanical device, and engineering each component to be between 8 and 50 times as strong as it needs to be in use, we have practically eliminated any possible failures.  For instance, the ultra-high strength polymer cable has a rated strength of 150 lbs.  We test every cable and pull ring sub-assembly to over 75 lbs. of pull force.  But the clamp requires less than 2 lbs of pull force to activate.  Therefore the cable and pull ring are rated at 37 times the required strength and should last your lifetime.  Every component on the JB-3 has been engineered and tested to the same high level.

Q: If I want to submit my purchase to my insurance company, what HCPCS might I use?

A: Some of our other customers have indicated that the claim might be best submitted using HCPCS code A4335 (Incontinence Supply; miscellaneous).  Other information for this code is That it became active January 01, 1990.  BETOS Classification is a Prosthetic/Orthotic Device.  Special Instructions apply to Medicare Coverage Status.  Please refer to Medicare Carriers Manual Reference Section Number 2130.  This information does not guarantee reimbursement and you should consult your insurance carrier for determining if your purchase is covered or not under your specific plan.
