Total Claims: 12
Claim 1
Independent Claim
196 words
An end-to-end inflatable lumbar traction harness for encircling and semi-suspending a patient in a variety of orthopedic positions comfortably while the gravitational pull on the patient's own body releases pressure on the spine for immediate back pain relief wherein the improvement comprises: (a) a bag shaped as the quarter section of a ring with a circular cross-section; (b) said bag enclosing an airtight bladder, which completely fills the bag from end-to-end when inflated; (c) said bag having affixed to it a stop valve to adjust the air pressure around the patient for personalized comfort while in suspension and to let air out of the bladder for lowering the patient into different body positions or into increased or decreased traction; (d) said bag, when inflated having a smooth, curved inside surface that can be moved along the spine by the patient while in traction to position the harness for maximum pain relief; (e) said bag having means for pinpointing the traction force and for assisting in opening the spinal segments, said means comprising an isolating seam; and (f) said bag having hook and loop type fasteners on the inside surface for the attachment of the above means.
