Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
227 words
A gravity traction vest for secure attachment to a patient, the patient having a torso with a rib cage having a plurality of ribs including a lowest rib, said vest adapted to be secured to the patient and attached to a support structure whereby the patient is suspended from the support structure with the head of the patient in an upward direction, said vest comprising: (a) a torso surrounding member having upper and lower edges and inner and outer surfaces for encircling the torso and rib cage of the patient; (b) support means cooperatively connected to said member and adapted to be attached to the support structure for suspending said member from the support structure and applying a uniform force on said member in said upward direction; (c) attachment means for securing said member to the patient; and (d) a flexible cushion insert means extending along at least a portion of said lower edge of said inner surface of said member and protruding inwardly toward the patient for engagement below the lowest rib, wherein when said vest is attached about the patient's rib cage, substantially said entire insert means is positioned below the lowest rib and said insert means is urged inwardly toward the patient to a position wherein said insert means will restrain movement of said member caused by said force applied by said support means.
Claim 2
Dependent Claim
227 words
A gravity traction vest for secure attachment to a patient, the patient having a torso with a rib cage having a plurality of ribs including a lowest rib, said vest adapted to be secured to the patient and attached to a support structure whereby the patient is suspended from the support structure with the head of the patient in an upward direction, said vest comprising: (a) a torso surrounding member having upper and lower edges and inner and outer surfaces for encircling the torso and rib cage of the patient; (b) support means cooperatively connected to said member and adapted to be attached to the support structure for suspending said member from the support structure and applying a uniform force on said member in said upward direction; (c) attachment means for securing said member to the patient; and (d) a flexible cushion insert means extending along at least a portion of said lower edge of said inner surface of said member and protruding inwardly toward the patient for engagement below the lowest rib, wherein when said vest is attached about the patient's rib cage, substantially said entire insert means is positioned below the lowest rib and said insert means is urged inwardly toward the patient to a position wherein said insert means will restrain movement of said member caused by said force applied by said support means.
Claim 3
Dependent Claim
80 words
The vest of claim 1 wherein the vest attachment means includes a plurality of cinctures extending about the torso surrounding member when said vest is secured to the patient, and wherein said insert means protrudes from the inner surface of the vest immediately opposite the lowermost of said cinctures, wherein, when said lowermost cincture is tightened with the vest positioned along the patient's torso so that said insert means is immediately below the bottom surface of the patient's lowermost rib.
Claim 4
Dependent Claim
56 words
The vest of claim 2 wherein the torso surrounding member includes a back portion, a pair of lateral portions, and a pair of overlappable front portions, and wherein the cushion insert means extends along the lower edge of the inner surface of each of the lateral portions of said torso surrounding member and protrudes inwardly therefrom.
