Method and Device for Enhanced Blood Flow

Abstract

A non-invasive method and device for promoting a localized change in a flow of blood through a blood vessel in a limb segment of a body by a series of electrically stimulated contractions of muscle tissue in the limb segment, the method including the steps of: (a) providing a device including: (i) first, second and third electrodes, each adapted to operatively contact the limb segment; (ii) a signal generator, operatively connected to the electrodes, adapted to produce a series of electrical impulses to the limb segment via the electrodes, and (iii) a control unit adapted to control the signal generator to produce the series of electrical impulses; (b) positioning the electrodes on the limb segment, wherein the first electrode is positioned on a lower end of the lower leg, the second electrode is positioned on the lower leg, and the third electrode is positioned on an upper end of the lower leg, whereby the first and third electrodes are disposed on opposite ends of the lower leg, and the second electrode and one of the first and third electrodes are disposed on a same end of the lower leg; (c) effecting a sequence of muscular contractions of the lower leg, by operations including: (i) applying a first electrical impulse between the electrodes on the same end of the lower leg to induce a first muscular contraction of a first portion of the tissue; and (ii) applying at least a second electrical impulse between the first and third electrodes to induce a longitudinal muscular contraction of a second portion of the muscular tissue; and (d) repeating operations (i) and (ii), to repeatedly induce the contractions, to effect the increased flow of blood.

Problems solved by technology

The efficacy of this personnel-intensive art varies with the experience and technique of the individual massage therapist, and therefore cannot be prescribed in an adequately standardized form.

More importantly, the improvement in blood circulation is also of an extremely limited magnitude.

Any increase in blood circulation is so modest that it is often undetectable using conventional flow-measuring equipment.

Hence, EMS methods, like therapeutic massage, hot-water treatments, etc. are incapable of providing a major increase in the localized flow of blood.

Moreover, because the excitation is random, EMS methods are fundamentally incapable of providing a decrease in the localized flow of blood.

These treatments are of further disadvantage in that they require various device elements to be contacted with the skin.

These elements generally cause discomfort to the patient, and require changing and cleaning after each use in order to ensure good sanitary conditions.
