Abstract
Abstract A device for normally applying compressive pressures with a pair of sleeves against a patient's limbs from a source of pressurized fluid. The device has a first elongated pressure sleeve for enclosing a length of the patient's limb having fluid pressure chambers in the sleeve. The device has an apparatus for intermittently inflating and deflating the pressure chambers, and a device for simulating operation of one of the sleeves when only the other sleeve is in use, with the simulating device being connected to the inflating apparatus.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
92 words
A device for normally applying compressive pressures with a pair of sleeves against a patient's limbs from a source of pressurized fluid, comprising: first and second elongated pressure sleeves for enclosing a length of the patient's limbs having chamber means; means for intermittently inflating and deflating the chamber means; and means for simulating operation of said second sleeve when only said first sleeve is in use or to simulate operation of said first sleeve when only said second sleeve is in use, with the simulating means being connected to the inflating means.
Claim 2
Independent Claim
92 words
A device for normally applying compressive pressures with a pair of sleeves against a patient's limbs from a source of pressurized fluid, comprising: first and second elongated pressure sleeves for enclosing a length of the patient's limbs having chamber means; means for intermittently inflating and deflating the chamber means; and means for simulating operation of said second sleeve when only said first sleeve is in use or to simulate operation of said first sleeve when only said second sleeve is in use, with the simulating means being connected to the inflating means.
Claim 3
Independent Claim
151 words
A device for normally applying compressive pressures with a pair of sleeves against a patient's limbs from a source of pressurized fluid, comprising: first and second elongated pressure sleeves for enclosing a length of the patient's limbs, said sleeve having a plurality of laterally extending separate fluid pressure chambers progressively arranged longitudinally along the sleeve from a lower portion of the limb to an upper portion of the limb proximal the patient's heart relative to said lower portion; conduit means for establishing communication between the fluid source and the sleeve chambers of said sleeves; means for intermittently inflating and deflating said pressure chambers of said sleeves through the conduit means; and means for simulating operation of said second sleeve when only said first sleeve in use or to simulate operation of said first sleeve when only said second sleeve is in use, with the simulating means communicating with the inflating means.
Claim 4
Independent Claim
151 words
A device for normally applying compressive pressures with a pair of sleeves against a patient's limbs from a source of pressurized fluid, comprising: first and second elongated pressure sleeves for enclosing a length of the patient's limbs, said sleeve having a plurality of laterally extending separate fluid pressure chambers progressively arranged longitudinally along the sleeve from a lower portion of the limb to an upper portion of the limb proximal the patient's heart relative to said lower portion; conduit means for establishing communication between the fluid source and the sleeve chambers of said sleeves; means for intermittently inflating and deflating said pressure chambers of said sleeves through the conduit means; and means for simulating operation of said second sleeve when only said first sleeve in use or to simulate operation of said first sleeve when only said second sleeve is in use, with the simulating means communicating with the inflating means.
Claim 5
Dependent Claim
15 words
The device of claim 2 wherein the simulating means is connected to the conduit means.
Claim 6
Dependent Claim
46 words
The device of claim 2 wherein the conduit means comprises a plurality of conduits having lumens, and the simulating means comprises elastic wall means closing a plurality of the conduit lumens with the wall means having slit means to permit passage of fluid therethrough under pressure.
Claim 7
Dependent Claim
63 words
The device of claim 4 wherein the conduits have downstream ends, and in which the simulating means further comprises an elastic wall having a plurality of hollow tubular sections extending from the wall to receive said conduit ends, said wall having a plurality of slits extending through the wall and communicating with the tubular sections to permit passage of fluid under pressure therethrough.
Claim 8
Dependent Claim
127 words
A simulator for either one of a pair of elongated pressure sleeves of the type having a plurality of laterally extending separate fluid pressure chambers progressively arranged longitudinally along the sleeve from the lower portion of a patient's limb to an upper portion of the limb proximal the patient's heart relative to said lower portion, said simulator comprising, an elastic wall, and a plurality of hollow tubular sections extending from the wall, said wall having a plurality of slits extending through the wall and communicating with at least a portion of the tubular sections to permit passage of fluid under pressure through the wall slits said simulater being functional to simulate operation of one of said sleeves when only the other of said sleeves is in use.
Claim 9
Dependent Claim
127 words
A simulator for either one of a pair of elongated pressure sleeves of the type having a plurality of laterally extending separate fluid pressure chambers progressively arranged longitudinally along the sleeve from the lower portion of a patient's limb to an upper portion of the limb proximal the patient's heart relative to said lower portion, said simulator comprising, an elastic wall, and a plurality of hollow tubular sections extending from the wall, said wall having a plurality of slits extending through the wall and communicating with at least a portion of the tubular sections to permit passage of fluid under pressure through the wall slits said simulater being functional to simulate operation of one of said sleeves when only the other of said sleeves is in use.
Claim 10
Dependent Claim
18 words
The simulator of claim 6 wherein the tubular sections are generally aligned with each other along the wall.
