Hypobaric Sealing Membrane

Advanced Technology That's Easy to Live With

Iceross Seal-In^® liners incorporate a hypobaric sealing membrane (HSM) that conforms to the shape of the internal socket wall, providing an airtight seal. The HSM location is critical, and is specifically calculated to ensure the air is expelled quickly (in one or two steps) through a distally positioned expulsion valve*.

The hypobaric condition below the membrane ensures good suspension and rotational control of the prosthesis. The pressure will always be inversely proportional to the suspension force needed, ensuring superior stability, comfort, and control. The socket is released with a push of a button. It couldn't be more simple. It also couldn't be more comfortable, because the liner is made of DermoSil Silicone with Active Skin Care, promoting skin health while moisturizing and soothing the skin.
* Össur recommends the use of the Icelock^® 500 Series expulsion valves

Hypobaric Sealing Membrane (HSM)

• Patented sealing system, made of proprietary silicone blend, is bonded distally to the liner
• Conforms to socket shape, creating firm suspension
• Integrated recess provides even pressure around the seal
• Maintains firm suspension even through limb volume fluctuations
• Rotational stability is enhanced by the seal and distal pad adhesion
• With the HSM, the hypobaric pressure will always be in direct proportion to the suspension force needed, ensuring superior stability, comfort, and control

When fitting an Iceross Seal-In^® Liner

When fitting an Iceross Seal-In Liner a one-way, auto expulsion valve with push-button suction release must be used, because a standard one-way valve without a release mechanism feature to allow air back into the socket will not allow the socket to be removed.

Icelock^® Expulsion Valves

The Icelock expulsion valves are precision engineered, simple to install and designed specifically to be used with the Iceross Seal-In^® liners and the Iceross Seal-In^® X5 liners. They provide auto expulsion and push-button suction release.
