Abstract
Abstract A patient-lifting stretcher comprises a movable flexible frame formed of two closed longitudinal slideways between which there are movably mounted two parallel support sheets staggered with respect to each other which have one end in common provided with a reversing roller and two separate ends each having a reversing roller. Over these rollers and sheets there slide two cloths whose common end is connected to a fixed point and whose other ends, after passing over the rollers, are each firmly connected with a separate fixed point so that when the stretcher is displaced, one of the cloths moves under the body of the patient while the other, below this one, moves over the mattress or other surface which has until then directly sustained the body.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
112 words
Apparatus for supporting and transferring a patient, comprising: a framework comprising a pair of closed slideway tracks, said tracks being laterally spaced apart and being disposed in parallel generally vertical planes for positioning the tracks in stationary condition on sides of a flat support surface for a patient, the tracks having upper and lower, normally horizontal track portions and having a terminal track portion interconnecting ends of the horizontal track portions; and flexible stretcher means disposed to be guided by said track portions for positioning the flexible stretcher means, along said lower track portion, between the support surface and the patient to transfer the patient onto and from the flexible stretcher means.
Claim 2
Dependent Claim
112 words
Apparatus for supporting and transferring a patient, comprising: a framework comprising a pair of closed slideway tracks, said tracks being laterally spaced apart and being disposed in parallel generally vertical planes for positioning the tracks in stationary condition on sides of a flat support surface for a patient, the tracks having upper and lower, normally horizontal track portions and having a terminal track portion interconnecting ends of the horizontal track portions; and flexible stretcher means disposed to be guided by said track portions for positioning the flexible stretcher means, along said lower track portion, between the support surface and the patient to transfer the patient onto and from the flexible stretcher means.
Claim 3
Dependent Claim
17 words
Apparatus according to claim 1, in which the framework includes cross members interconnecting said upper track portions.
Claim 4
Dependent Claim
70 words
Apparatus according to claim 1, wherein each track has a generally U-shaped cross-sectional configuration the arms of which face laterally, each track including members extending toward one another from said arms; and the flexible stretcher means including roller means comprising pairs of horizontal rollers rolling respectively on said members, and a common vertical shaft supported by the rollers of each pair to support edge portions of the flexible stretcher means.
Claim 5
Dependent Claim
47 words
Apparatus according to claim 3 in which said flexible stretcher means comprises; a first support sheet having an edge portion supported by one of said shafts; and a second support sheet generally coextensive with the first and having an edge portion supported by another of said shafts.
Claim 6
Dependent Claim
28 words
Apparatus according to claim 4, in which said flexible stretcher means includes sheets of cloth, overlying opposite surfaces of each support sheet and longitudinally extending beyond the same.
Claim 7
Dependent Claim
66 words
Apparatus according to claim 5 in which said support sheets are interconnected at one of their ends; the roller means including cloth-reversing roller means supported by the interconnected ends and two additional roller means, each supported by said edge portion of one of said sheets and one being staggered with respect to the other, and said sheets of cloth having longitudinal ends secured to said framework.
Claim 8
Dependent Claim
13 words
Apparatus according to claim 5, in which said support sheets have slippery surfaces.
Claim 9
Dependent Claim
51 words
Apparatus according to claim 1, including a pair of pull chains, one on each slideway track, for moving end portions of the flexible stretcher means along the tracks; and a winch on the framework, disposed to move the chains for the moving of the end portions of the flexible stretcher means.
Claim 10
Dependent Claim
27 words
Apparatus according to claim 1, in which said terminal track portion is curved and is disposed to guide the flexible stretcher means in a correspondingly curved path.
