BLOOD CIRCULATING DEVICE
Abstract
A blood circulating device for the limbs of a body comprises a
pair of airtight sleeves each adapted to encase a corresponding
limb. 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.

Claims
I claim:
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.
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.
Description
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--II, of FIG.
1.
In the FIGS., 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 provided 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.
A source of compressed air 12 is coupled to both sleeves 4 and 5
via flexible tubing 13 and 14 (FIG. 1). The source of compressed
air 12 pulsatingly supplies air to each sleeve 4 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.
