Sub-Atmospheric Technology
The industry is growing and technology is advancing. At McKinney Prosthetics your needs are our focus by being educated in the latest technology with certifications as well as pioneering technology for the future!

As one of the first few people to develop elevated vacuum suspension, Ray McKinney has now become an expert in the industry regarding elevated vacuum. The science of Sub-Atmospheric Socket Technology manages the volume relationship between the prosthetic socket and the residual limb. Vacuum technology - greater than 15 in Hg - helps maintain consistent volume in the limb all day long.

Volume loss in the residual limb is a common side effect for prosthetic-wearing amputees that can lead to inconsistent fit, frequent prosthetic adjustments, tissue breakdown creating ulcers and abrasions, and premature wear on the prosthetic interface.

Our specialized knowledge and experience utilize vacuum technology to manage these common problems by:
• Equalizing pressures within the socket.
• Vaporizing perspiration within the socket.
• Maintaining a balanced volume in the residual limb, which minimizes movement of the limb within the socket.
• Enhancing connection between limb and the prosthesis for improved proprioception.
• Reducing friction between the limb and the liner and between the liner and the socket, which prevents tissue breakdown and extends the life of the prosthetic interface.

McKinney Prosthetics utilizes a proprietary vacuum pump designed specifically to have the benefits of being quiet, light weight, long battery life (3 weeks), cosmetic, and low profile. Our system can be fit into any shape of prosthesis for added convenience.

We have developed specialized socket styles for both above and below knee amputees that allows almost any limb to utilize the Sub-Atmospheric technology.
