Pre-Vent II Series® Pressure Redistributing Bariatric Foam Mattress System

Prevention by Suspension™

Pre-Vent II Series® Pressure Redistribution Mattress Systems

The Pre-Vent II Elite® bariatric therapeutic pressure redistributing foam mattress is the culmination of extensive research and testing. Blue Chip Medical’s exclusive Sphere™, Reflect™ SCT™, and Multi-Flex™ designs react to bodyweight displacement across the entire surface. This prevents and relieves pressure sores by keeping the body in a constant state of suspension; Prevention by Suspension™.

Pre-Vent II Series® Pressure Redistribution Mattress Systems

Our unique shapes together with our Med-Flex™ PPF™ foams, react instinctively to a compression set, allowing for a fully automatic, totally zoned surface. Other manufacturers’ surfaces are zone specific and must always take into consideration a patient’s weight, size (build), and shape. Blue Chip’s Sphere™ and Reflect™ designs act independently as its own self-adjusting, pressure-redistribution zone. Every component of the Pre-Vent II Series® medical foam mattress undergoes a strict protocol to ensure clinical efficacy, infection control standards, and durability for the life of the mattress.

certiPUR certified foam

All foams are Latex Free and CertiPUR-US® Certified to be made without: ozone depleters, PBDEs, TDCPP or TCEP (“Tris”) flame retardants, mercury, lead and other heavy metals, formaldehyde, phthalates regulated by the Consumer Product Safety Commission. CertiPUR-US® foams have Low VOC (Volatile Organic Compound) emissions for indoor air quality (less than 0.5 parts per million).

Pre-Vent II Series® Pressure Redistribution Mattress Systems Vyvex-ll 
Vyvex-ll™ is Nylon Butyl-backed top cover with a low moisture vapor transmission rate (MVTR). Vyvex-ll™ is fluid proof and offer low-shear, low-friction protection and are anti-microbial, fire retardant, stain-resistant and washable. This cover features Blue Chip’s exclusive Barrier Lok™ infection control system.


Med-Flex™ PPF™ (Pressurized Polymer Foaming) Manufacturing Process
PPF™ is the most modern manufacturing process used today. This process uses an enclosed controlled environment rather than a traditional open-line pour. PPF™ allows for the precision control of atmospheric pressures during manufacturing adding to the purity of the foam’s cell structure. This method greatly reduces the sag factor (deflection), thereby enhancing the product’s life and extending the uncompromising pressure-redistributing qualities of our foam mattress systems. PPF™ technology enables Blue Chip to warranty the longevity of our Pre-Vent II Series® mattresses to outlast all other conventional mattress systems.

Pre-Vent II Series® Pressure Redistribution Mattress Systems

Multi-Flex(R) PPF®
Multi-Flex™ PPF™
Multi-Flex™ PPF™ foam provides support for proper immersion and pressure redistribution by utilizing our exclusive compression technology to absorb the patient’s weight, providing ultimate comfort and pressure redistribution throughout the core of the mattress. This design used in conjunction with our Reflect™ SCT™ (Surface Cut Technology) creates the ultimate environment for the prevention and treatment of pressure ulcers.
The Sphere® The Sphere™
The patent-pending anatomically inspired sphere shape offers the most unique design the therapeutic support surface industry has ever seen. The Sphere™ design is clinically effective in redistributes the interface pressures which create pressure sores. Compressing the sphere down expands the surface area into a flat pressure-redistribution surface to evenly distribute and support the patient’s weight across the entire mattress surface. Each Sphere™ acts independently as its own self-adjusting pressure-redistribution zone. As the body moves across the mattress, the spheres’ touch points help stimulate blood flow. The Sphere™ design permits air circulation, reducing heat build-up which provides a much cooler, more comfortable support surface.
Reflect® SCT™ (Surface Cut Technology)
Reflect™ SCT(Surface Cut Technology)
Reflect™ SCT™ foam enables Blue Chip to produce a single piece of polyurethane foam with varying features and properties. We can alter the surface pattern, size, space, position, level and depth of cut. This engineering advancement produces a pressure-redistribution surface that gives unlimited comfort zones never thought possible in a single piece of foam. SCT™ allows the Reflect™ design to be stronger and more supportive with a greater surface area than conventional foam convolution. This design absorbs and distributes the impact-weight of the body to provide greater comfort, maximum support and to redistribute pressure around bony prominences.

Heel Wrap(R) PPF® Foam Heel Wrap(R) PPF® Foam
Heel Wrap™ PPF™ Foam
Exclusive Heel Wrap™ PPF™ foam is incorporated in the top layer of every Pre-Vent II Series® mattress system for maximum prevention of heel ulcers. For years, heel pillows have been buried beneath the top surface of the mattress. Blue Chip’s Heel Wrap™ PPF™ foam was brought to the surface to replace the fiber/foam pillow with individual, self-adjusting, pressure-redistribution zones. Heel Wrap™ PPF™ foam provides a cradle of comfort and support in the sensitive heel area with a softer foam that is more durable than conventional fiber/foam heel pillows.

Barrier Lok(TM) Infection Control System

Barrier Lok™ Infection Control System
Blue Chip’s exclusive Barrier Lok™ feature virtually seals and protects the inner foam core of the mattress by preventing the leaching of fluids from penetrating the perimeter seam of the mattress. The Barrier Lok™ ensures that infection control
standards are maintained, thereby providing investment protection on all Pre-Vent II Series® mattress systems.
Dual-Protection Slip Layer Dual-Protection Slip Layer
Our silk film slip layer eliminates friction between the inner foam core and the top cover. This allows both surfaces to move independently against one another extending the life of the mattress. In addition, the special silk film offers added protection against the leaching of fluids to the inner foam core.
Anti-Microbial Protection
All PPF™ foams and Vyvex™ mattress coverings are anti-microbial and effectively protect against bacterial growth. The anti-microbial additive used is proven to be effective against a wide spectrum of micro-organisms, including (MRSA), mold, mildew, staining and odors caused by fungal organisms. CA16 additive for additional protection is available upon request.

Secure Guard(R)
Secure Guard™
Eliminates mattress movement during patient transfers and nursing care. This Multi-purpose accessory allows the mattress to be secured to the bed frame while doubling as a flat sheet hold-down device. Secure Guard™ is an option on all Prevent models.
SRS® - Safety Rail System & PSB® SRS™ – Safety Rail System & PSB™ – Perimeter Safety Bolster
The PSB™ Perimeter Safety Bolster is Standard on all Prevent II Series® Mattress Systems. The SRS™ Safety Rail System can be added to any model to reduce the risk of patient falls. Both systems comply with the new FDA patient entrapment guidelines. Both Systems are made with the same Med-Flex™ PPF™ foam used in the Prevent II Series® Mattresses. SRS™ is a raised side rail system.
