Patent Images
1. Apparatus for promoting blood circulation in a body area of a patient comprising:
- an inflatable cuff means adapted to be attached to a part of the patient for applying pressure to such part upon inflation of the cuff means,means for supplying fluid under pressure,conduit means interconnected between said pressure supply and said cuff means for transmitting fluid under pressure from said pressure supply to said cuff means,means for controlling the flow of fluid through said conduit means for controlling the inflation of said cuff means,means for sensing the heartbeat of the patient, andmeans for sensing the blood flow in a part of the patient distal to said cuff means.

Abstract
Apparatus for promoting blood circulation in a body part suffering from a circulation deficiency by inflating and deflating a pressure cuff applied to a patient'"'"'s limb proximal to the affected body part so that the blood is forced into the affected body part. The apparatus is synchronized with the patient'"'"'s heartbeat by way of an EKG pickup and automatically compensates for the blood transit time from the heart to the point of cuff application. The apparatus includes control means responsive to the sensing of the blood flow at a location distal to the cuff for achieving optimum blood circulation in the body part being treated.

8. Apparatus for promoting blood circulation in a body area of a patient comprising:
-
an inflatable cuff means adapted to be attached to a part of the patient for applying pressure to such part upon inflation of the cuff means, means for supplying fluid under pressure, conduit means interconnected between said pressure supply and said cuff means for transmitting fluid under pressure from said pressure supply to said cuff means, and means for controlling the flow of fluid through said conduit means for controlling the inflation of said cuff means, said control means including valve means controlling flow through said conduit means and a valve drive for actuating said valve means between a pair of flow controlling positions, said fluid pressure supply including for supplying fluid under a positive pressure condition and means for supplying fluid under a negative pressure condition, and means for connecting said positive and said negative pressure supply to said valve means, said valve means being operative to connect said positive pressure supply to said cuff means in one of said flow controlling positions thereof to cause inflation of said cuff means and to connect said negative pressure supply to said cuff means in the other flow controlling position thereof to cause deflation of said cuff means. - View Dependent Claims (9, 10)
