A steady slow air release valve is provided in each sleeve for slowly releasing air in the corresponding sleeve. A source of compressed air is coupled to both sleeves and pulsatingly supplies air to each sleeve thereby encouraging blood circulation in the encased limbs.
2 Claims, 2 Drawing Figures BLOOD CIRCULATING DEVICE DESCRIPTION OF THE INVENTION The present invention relates to a blood circulating device. More particularly, the invention relates to a blood circulating device for the limbs of a body.
Objects of the invention are to provide a blood circulating device for the limbs of the body, which device is of simple structure, inexpensive to manufacture, easy and convenient in application and removal, which functions efficiently, effectively and reliably to encourage blood circulation in the limbs thereby preventing venous blood stasis to prevent clot formation in the veins of the limbs, specifically the legs.
In order that the invention may be readily carried into effect, it will now be described with reference to the accompanying drawing, wherein:
FIG. 1 is a schematic diagram of an embodiment of the blood circulating device of the invention in use; and
FIG. 2 is a sectional view, taken along the lines II-Il, of FIG. I. 7
In the F1GS., the same components are identified by the same reference numerals.
The blood circulating device of the invention is for the limbs, more specifically the legs 1 and 2 of a body 3 (FIG. 1).
The blood circulating. device of the invention comprises a pair of airtight sleeves 4 and 5, each adapted to encase a corresponding limb 1 and 2, respectively, of the body 3.
Each sleeve, as illustrated in FIG. 2 for the sleeve 4, has an inner wall 6 adjacent the limb 1 and an outer wall 7 spaced from the inner wall.
A zipper such as, for example, zippers 8 and 9, is provided in each sleeve for facilitating application and removal of the sleeve.
A steady slow air release valve 10 is provided in the sleeve 4 and a steady slow air release valve 11 is pro vided in the sleeve 5 for slowly releasing air in the corresponding sleeve. This type of valve may comprise any suitable valve known in the art for accomplishing this result. 1
A source of compressed air 12 is coupled to both sleeves 4 and 5 via flexible tubing 13 and 14 (FIG. I). The source of compressed air 12 pulsatingly supplies air to each sleeve 41 and 5 thereby encouraging blood circulation in the encased limbs. The air is pulsatingly supplied to the space 15, as shown in FIG. 2 for the sleeve 4, between the inner and outer walls 6 and 7. In the sleeve 4, the air is slowly released from the space 15 via the valve 10.
While the invention has been described by means of a specific example and in a specific embodiment, I do not wish to be limited thereto, for obvious modifications will occur to those skilled in the art without departing from the spirit and scope of the invention.
1. A blood circulating device for the limbs of a body,
said device comprising a pair of airtight sleeves each adapted to encase a corresponding limb of a body, each sleeve having an inner wall adjacent the limb and an outer wall spaced from the inner wall;
a pair of steady slow air release valves each in a corresponding one of the sleeves for slowly releasing air in the corresponding sleeve; and
a source of compressed air coupled to both sleeves at points spaced from the air release valves and means for pulsatingly supplying air to each sleeve between the inner. and outer walls thereby encouraging blood circulation in the encased limbs, the air being slowly released from the sleeves via said valves. I
2. A blood circulating device as claimed in claim 1,
further comprising a zipper in each sleeve for facilitating application and removal of the sleeve.
