Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
81 words
A method of pressurizing a multi-chambered sleeve which is wrapped about a patient's limb, the method comprising the steps of: pressurizing an accumulator housing with fluid; providing a port assembly in said housing having an inlet arranged in communication with a conduit arrangement for pressurizing said multi-chambered sleeve; sequentially opening and closing said port assembly inlet arrangement; sequentially ducting pressurized fluid through said port assembly to said conduit arrangement for communications with said sleeve to pressurize the chambers of said sleeve.
Claim 2
Independent Claim
81 words
A method of pressurizing a multi-chambered sleeve which is wrapped about a patient's limb, the method comprising the steps of: pressurizing an accumulator housing with fluid; providing a port assembly in said housing having an inlet arranged in communication with a conduit arrangement for pressurizing said multi-chambered sleeve; sequentially opening and closing said port assembly inlet arrangement; sequentially ducting pressurized fluid through said port assembly to said conduit arrangement for communications with said sleeve to pressurize the chambers of said sleeve.
Claim 3
Dependent Claim
26 words
A method of pressurizing a multi-chambered sleeve as recited in claim 1, including: rotating a pump within said accumulator; and discharging said pump in said accumulator.
Claim 4
Dependent Claim
34 words
A method of pressurizing a multi-chambered sleeve as recited in claim 2, including: moving a stopper with respect to each of said conduits of said port assembly to permit the opening and closing thereof.
Claim 5
Dependent Claim
43 words
A method of pressurizing a multi-chambered sleeve as recited in claim 3, including: rotating a plurality of cam elements within said accumulator; and following said cam elements with cam followers to permit the moving of said stoppers which open and close said conduits.
Claim 6
Dependent Claim
31 words
A method of pressurizing a multi-chambered sleeve, as recited in claim 4, including: detecting the position of said stoppers; regulating the rotation of said cam elements responsive to said stopper detection.
Claim 7
Dependent Claim
28 words
A method of pressurizing a multi-chambered sleeve as recited in claim 5, including: dumping the pressurized fluid of said accumulator when the pressure therein reaches a predetermined limit.
Claim 8
Independent Claim
51 words
A method of pressurizing a multi-chambered pressurizable sleeve which is wrappable about a patient's limb, comprising the steps of: pressurizing an accumulator housing with fluid under pressure by means within said housing; sequentially discharging portions of that fluid under pressure through a conduit means to said chambers of said multi-chambered sleeve.
Claim 9
Independent Claim
51 words
A method of pressurizing a multi-chambered pressurizable sleeve which is wrappable about a patient's limb, comprising the steps of: pressurizing an accumulator housing with fluid under pressure by means within said housing; sequentially discharging portions of that fluid under pressure through a conduit means to said chambers of said multi-chambered sleeve.
Claim 10
Dependent Claim
54 words
A method of pressurizing a pressurizable sleeve as recited in claim 7, including: rotating a pump within said accumulator housing to bring fluid from outside of said housing; discharging said pump in said accumulator housing; housing a port assembly within said accumulator housing to effectuate the discharge of pressurized fluid from said accumulator housing.
Claim 11
Dependent Claim
34 words
A method of pressurizing a pressurizable sleeve as recited in claim 8, including: timing the opening of conduits in said port assembly as to sequentially the portions of pressurized fluid from said housing accumulator.
Claim 12
Dependent Claim
38 words
A method of pressurizing a pressurizable sleeve as recited in claim 9, including: closing said conduits in said port assembly in a timed sequential manner so as to stop the discharge of pressurized fluid from said accumulator housing.
Claim 13
Dependent Claim
27 words
A method of pressurizing a pressurizable sleeve as recited in claim 10, including: governing the opening and closing of said port assembly conduits by a detector means.
Claim 14
Dependent Claim
35 words
A method of pressurizing a pressurizable sleeve as recited in claim 11, including: dumping the pressurized fluid from said accumulator housing by a dump valve if the pressure within said accumulator exceeds a pre-set limit.
