Abstract
Abstract A method for reducing the risk of incurring venous thrombosis in operative and post-operative patients. Vibration and/or massage is imparted to the legs of a patient during and after surgery. The vibration and/or massage aids muscular activity in the legs, which in turn stimulates the blood vessels reducing the probability of formation of a blood clot therein.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
87 words
A method of reducing the risk of incurring venous thrombosis in the legs of operative, bedridden and post-operative patients, comprising the steps of: A. supporting the legs of the patient so as to allow the legs to receive external stimuli during surgery; B. anesthetizing the patient for the purpose of performing surgery; and C. applying external stimulation to at least one leg of said patient while so anesthetized during surgery, so as to aid muscular activity in said leg, thereby reducing the risk of incurring venous thrombosis.
Claim 2
Independent Claim
87 words
A method of reducing the risk of incurring venous thrombosis in the legs of operative, bedridden and post-operative patients, comprising the steps of: A. supporting the legs of the patient so as to allow the legs to receive external stimuli during surgery; B. anesthetizing the patient for the purpose of performing surgery; and C. applying external stimulation to at least one leg of said patient while so anesthetized during surgery, so as to aid muscular activity in said leg, thereby reducing the risk of incurring venous thrombosis.
Claim 3
Dependent Claim
15 words
The method of claim 1, wherein said external stimulation comprises applying vibration to said leg.
Claim 4
Dependent Claim
15 words
The method of claim 1, wherein said external stimulation comprises applying massage to said leg.
Claim 5
Dependent Claim
21 words
The method of claim 1, further comprising the step of: C. elevating at least one leg of said patient during surgery.
Claim 6
Dependent Claim
20 words
The method of claim 1, wherein said stimulation is additionally applied to the leg of said patient during post-operative care.
Claim 7
Independent Claim
142 words
A method practiced during surgery which will reduce the risk of incurring venous thrombosis in the legs of operative patients, comprising the steps of: A. supporting upon an operating table, at least one flexible leg supporting member containing a fluiD; B. supporting at least one leg of said operative patient upon said flexible leg supporting member; C. during surgery of said patient, inducing perturbations in the fluid of said flexible leg supporting member; D. during surgery of said patient, transmitting the perturbations from the fluid through said flexible leg supporting member, to the supported leg of said patient which is supported by said flexible leg supporting member; and E. during surgery of said patient, stimulating the leg of the patient supported by said flexible leg supporting member by means of said perturbations in order to reduce the risk of incurring venous thrombosis.
Claim 8
Independent Claim
142 words
A method practiced during surgery which will reduce the risk of incurring venous thrombosis in the legs of operative patients, comprising the steps of: A. supporting upon an operating table, at least one flexible leg supporting member containing a fluiD; B. supporting at least one leg of said operative patient upon said flexible leg supporting member; C. during surgery of said patient, inducing perturbations in the fluid of said flexible leg supporting member; D. during surgery of said patient, transmitting the perturbations from the fluid through said flexible leg supporting member, to the supported leg of said patient which is supported by said flexible leg supporting member; and E. during surgery of said patient, stimulating the leg of the patient supported by said flexible leg supporting member by means of said perturbations in order to reduce the risk of incurring venous thrombosis.
Claim 9
Dependent Claim
11 words
The method of claim 6, wherein said perturbations are vibratory perturbations.
Claim 10
Dependent Claim
15 words
The method of claim 6, wherein both legs of said patient are supported and stimulated.
Claim 11
Dependent Claim
24 words
The method of claim 6, wherein said stimulating perturbations provide massage to the leg being supported by said flexible leg supporting member during surgery.
Claim 12
Independent Claim
160 words
A method practiced during surgery which will induce stimulation to the legs of operative patients, thereby reducing the risk of incurring venous thrombosis, said method comprising the steps of: A. supporting upon an operating table, at least one flexible leg supporting member comprising stimulation generating means for generating vibratory stimulation, and stimulation generating means for generating massaging stimulation, the generated stimulation being imparted to at least one leg of an operative patient which is supported upon said flexible leg supporting member; B. supporting at least one leg of said operative patient upon said flexible leg supporting member during surgery; C. during surgery of said patient, activating at least one of said stimulation generating means in order to generate stimulation for the leg supported by said flexible leg supporting member; and D. during surgery of said patient, imparting the generated stimulation to the leg supported by said flexible leg supporting member in order to reduce the risk of incurring venous thrombosis.
Claim 13
Independent Claim
160 words
A method practiced during surgery which will induce stimulation to the legs of operative patients, thereby reducing the risk of incurring venous thrombosis, said method comprising the steps of: A. supporting upon an operating table, at least one flexible leg supporting member comprising stimulation generating means for generating vibratory stimulation, and stimulation generating means for generating massaging stimulation, the generated stimulation being imparted to at least one leg of an operative patient which is supported upon said flexible leg supporting member; B. supporting at least one leg of said operative patient upon said flexible leg supporting member during surgery; C. during surgery of said patient, activating at least one of said stimulation generating means in order to generate stimulation for the leg supported by said flexible leg supporting member; and D. during surgery of said patient, imparting the generated stimulation to the leg supported by said flexible leg supporting member in order to reduce the risk of incurring venous thrombosis.
Claim 14
Dependent Claim
19 words
The method of claim 10, wherein both of said stimulation generating means are activated during surgery of said patient.
Claim 15
Dependent Claim
18 words
The method of claim 10, wherein both legs of the operative patient are supported and stimulated during surgery.
