Abstract
Abstract A portable lumbo-sacral traction apparatus having a U-shaped supporting frame, a suspension belt adapted to be worn around the lower thoracic region of the patient and means releasably securing the suspension belt to the U-shaped frame so that the frame applies upward force to the belt to remove weight from the lower lumbo-sacral and pelvic regions of a patient when a patient is being acted upon by the apparatus.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
153 words
A portable lumbo-sacral traction apparatus comprising: a free-standing integrally formed U-shaped supporting frame; a suspension belt adapted to be worn around the lower thoracic region of a patient rigidly and releasably secured to such frame, said belt including at least one pre-shaped encircling member adapted to extend substantially completely around the lower thoracic region of a patient, means for releasably securing said encircling member about the lower thoracic region of a patient, a cushioning pad contiguous with said encircling member and adapted to at least partially encircle the lower thoracic region of a patient with said encircling member, and means joining said encircling member to said cushioning pad; and means releasably securing said suspension belt to said U-shaped frame whereby the U-shaped frame applies upward tension to the suspension belt to remove weight from the lower lumbo-sacral and pelvic regions of a patient when a patient is being acted upon by the apparatus.
Claim 2
Dependent Claim
153 words
A portable lumbo-sacral traction apparatus comprising: a free-standing integrally formed U-shaped supporting frame; a suspension belt adapted to be worn around the lower thoracic region of a patient rigidly and releasably secured to such frame, said belt including at least one pre-shaped encircling member adapted to extend substantially completely around the lower thoracic region of a patient, means for releasably securing said encircling member about the lower thoracic region of a patient, a cushioning pad contiguous with said encircling member and adapted to at least partially encircle the lower thoracic region of a patient with said encircling member, and means joining said encircling member to said cushioning pad; and means releasably securing said suspension belt to said U-shaped frame whereby the U-shaped frame applies upward tension to the suspension belt to remove weight from the lower lumbo-sacral and pelvic regions of a patient when a patient is being acted upon by the apparatus.
Claim 3
Dependent Claim
41 words
The apparatus as claimed in claim 1 wherein the U-shaped frame has a connecting segment with a link substantially the width of the hips of a patient and upstanding legs of a length less than the length of the connecting segment.
Claim 4
Dependent Claim
42 words
The apparatus as claimed in claim 1 wherein said suspension belt further includes means for securing said cushioning pad at least partially about the lower thoracic region of a patient, and said U-shaped member is substantially uniform in thickness and in width.
Claim 5
Dependent Claim
17 words
The apparatus as claimed in claim 1 wherein said suspension belt pre-shaped encircling member is substantially rigid.
Claim 6
Dependent Claim
23 words
The apparatus as claimed in claim 2 wherein said frame connecting member is substantially flat to enable uniform contact with the supporting surface.
Claim 7
Dependent Claim
64 words
The apparatus as claimed in claim 5 wherein said suspension belt further includes means for securing said cushioning pad at least partially about the lower thoracic region of a patient and the supporting frame and connected suspension belt are movable with respect to each other to enable a patient to walk and move about while the suspension belt is encircling the lower thoracic region.
Claim 8
Dependent Claim
38 words
The apparatus as claimed in claim 2 wherein the frame upstanding legs are adjustable with and releasably securable to said connecting segment to enable an adjustable application of force when a patient is acted upon by the apparatus.
Claim 9
Dependent Claim
38 words
The apparatus as claimed in claim 5 wherein the frame upstanding legs are adjustable with and releasably securable to said connecting segment to enable an adjustable application of tension when a patient is acted upon by the apparatus.
Claim 10
Dependent Claim
17 words
The apparatus as claimed in claim 8 wherein said suspension belt pre-shaped encircling member is substantially rigid.
Claim 11
Dependent Claim
31 words
The apparatus as claimed in claim 9 wherein the supporting frame upstanding legs are arcuately shaped and extend upwardly to uniformly engage the hip, waist, and lower chest regions of patient.
