What is a balanced valve and what are the benefits of this type of design?

A balanced valve design means that the internal forces from pressure are equal. The forces from air pressure that open the valves are equal to the forces from air pressure that close the valves. In engineering school, engineers are taught to draw a “free body diagram” of the part in question and then apply all forces to that “free body.” With this type valve design, the forces from the pressure will be equal in both directions.

When a patient is immobilized for a period of time, fluids can “pool” in the lower legs, creating the potential for serious medical complications. The pressurizing foot cuff simulates the action of walking by sending pressure pulses to an inflatable pad under the arch of the foot. Both impulse length and intervals can be set to prescribed limits based on the patient’s needs.

Humphrey’s customvalve manifold met the target flow rate, spatial requirements, low current consumption and life cycle performance. This enabled the customer to create a lightweight, portable oxygen concentrator, eliminating the need to pull relatively heavy oxygen tanks with limited supply.

Humphrey’s custom valve assembly enabled customer to create a ventilator that met the respiratory care needs of both adults, and infants and young children. No longer will hospitals need to purchase two separate ventilators.
