Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
177 words
A patient support apparatus useful during x-raying comprising: a frame for supporting a bed surface having a length and a width and a head end and a foot end wherein said frame has a graduated scale along the length of at least one side thereof; a base for supporting said frame; an x-ray film cartridge shuttle; means located on said frame for supporting said x-ray film cartridge shuttle thereon and permitting movement of said x-ray film cartridge shuttle along the length of said frame; a rod for positioning said x-ray film cartridge shuttle along the length of said frame wherein said rod has a graduated scale along the length thereof and the units of said graduated scale of said rod correspond to the units of said graduated scale of said frame; a first end of said rod having means for engaging said x-ray film cartridge shuttle; and said engaging means comprising: a pin inserted through the diameter of said first end of said rod; and a spring surrounding the diameter of said first end of said rod.
Claim 2
Dependent Claim
177 words
A patient support apparatus useful during x-raying comprising: a frame for supporting a bed surface having a length and a width and a head end and a foot end wherein said frame has a graduated scale along the length of at least one side thereof; a base for supporting said frame; an x-ray film cartridge shuttle; means located on said frame for supporting said x-ray film cartridge shuttle thereon and permitting movement of said x-ray film cartridge shuttle along the length of said frame; a rod for positioning said x-ray film cartridge shuttle along the length of said frame wherein said rod has a graduated scale along the length thereof and the units of said graduated scale of said rod correspond to the units of said graduated scale of said frame; a first end of said rod having means for engaging said x-ray film cartridge shuttle; and said engaging means comprising: a pin inserted through the diameter of said first end of said rod; and a spring surrounding the diameter of said first end of said rod.
Claim 3
Dependent Claim
36 words
The patient support apparatus of claim 1 wherein the first end of said x-ray film cartridge shuttle has an aperture having a shape corresponding to the cross-section of said rod and pin inserted through said rod.
Claim 4
Dependent Claim
164 words
In a patient support apparatus useful during x-raying comprising a frame for supporting a bed surface having a length and a width and a head end and a foot end, a base for supporting said frame; an x-ray film cartridge shuttle; means located on said frame for supporting said x-ray film cartridge shuttle thereon and permitting movement of said x-ray film cartridge shuttle along the length of said frame; and a rod for positioning said x-ray film cartridge shuttle along the length of said frame, the improvement comprising: means defining a graduated scale along the length of at least one side of said frame, and means defining a corresponding graduated scale along the length of said rod such that a technician standing at an end of said frame may precisely position said shuttle to a selected position along said frame, as determined from a selected point on said scale along said frame, by reference to a corresponding point on said scale along said rod.
Claim 5
Dependent Claim
164 words
In a patient support apparatus useful during x-raying comprising a frame for supporting a bed surface having a length and a width and a head end and a foot end, a base for supporting said frame; an x-ray film cartridge shuttle; means located on said frame for supporting said x-ray film cartridge shuttle thereon and permitting movement of said x-ray film cartridge shuttle along the length of said frame; and a rod for positioning said x-ray film cartridge shuttle along the length of said frame, the improvement comprising: means defining a graduated scale along the length of at least one side of said frame, and means defining a corresponding graduated scale along the length of said rod such that a technician standing at an end of said frame may precisely position said shuttle to a selected position along said frame, as determined from a selected point on said scale along said frame, by reference to a corresponding point on said scale along said rod.
Claim 6
Dependent Claim
