Abstract

The object of the invention is to provide an ambulatory therapeutic brace that substantially supports the lumbar or stomach area with a pneumatically cushioned and heated air chamber (24). A belt (20) surrounds the waist and contains an air chamber (24) on the back inner surface. A heater (26) is embedded integrally with the chamber and is controlled in intensity by a switch (38) attached to the belt or is integral with a buckle (22). The chamber may be inflated by a manual bulb (28), a compressed air source, or an integral electrically operated pump (46).

Claims

1. A heated lumbar positioned air inflatable physiotherapeutic brace comprising:

(a) a belt completely encircling one'"'"'s waist in a conformal manner with said belt having ends therewith; and

a buckle attached permanently to one end of said belt receiving and removably captivating the other end,

(b) an air chamber integral with said belt on the surface contiguously engaging a persons lumbar area creating resilient yielding homogeneous pressure,

(c) a heater integrally embedded within said air chamber providing an elevated temperature within the brace providing physiologic relief of muscle myositis in the form of stress, strain, or fatigue, said heater further comprises metallic resistance wires embedded into the structure of the air chamber that is in physical contact with one'"'"'s lumbosacral region, the wires having a resistance such that when an electrical current is passed therethrough that the energy is transformed into heat directly dissipated to the wearer'"'"'s body, said resistance wires are separated into a plurality of circuits allowing a step control of the intensity of the heat conducted from the brace to one'"'"'s body, said resistance wires further comprise an alternating current electrical power source and a direct current power source duplicating said resistance wires in such a manner as to provide heating when connected to either source independent of the other, said heater further having control means in the form of a manual switch having contact points for conducting electricity through circuits of said heater providing steps control of resistance for capacity modulation, and,

(d) means to inflate said air chamber to a pressure of sufficient intensity to provide a biomechanical restriction to specific muscles in the lumbar region for the ambulatory management of low back pain, said means to inflate further comprise a hand actuated bulb, having a manual valve, associateably joined to said air chamber and self-sealing disconnect means functioning such that said chamber is inflated by the squeezing of one'"'"'s hand on the bulb increasing pneumatic pressure within the chamber using manual force which causes the bulb to become smaller in volume, driving air into the chamber and removal of the bulb without the loss of pressure characterized by the self-sealing function of the quick disconnect means.
