5,146,625 and 5,062,414 in the description of related
technology.
SUMMARY OF THE INVENTION
[0008] The invention is directed to a portable support device for
applying supportive pressure selectively such that a confined area
is not subject to the supportive pressure of the other areas. The
device also assists in reducing gravitational, or other,
compression of the vertebrae in a person's spine.
[0009] Other objects, advantages and novel features of the present
invention will become apparent from the following detailed
description of the invention when considered in conjunction with
the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] The preferred embodiment of the invention provides a
belt-like support device which is designed to be strapped around
the waist or other part of a person's body. The device is easily
adjustable. In one embodiment it is adjustable by adding or
removing panels to add length to the belt. As will be come clear
from the following description, the belt portions may be cut to
shorten the belt length or longer belt portions may be used to
lengthen the belt.
[0018] Panels are depicted in the drawing and they are of similar
size and shape, however, it should be evident that panels of
different lengths, widths and shapes are contemplated. In one
preferred embodiment the device is generally shaped to fit the
human torso and cover an area of the back between the shoulders and
hips. The device includes structure which prevents pressure on a
prescribed back area, such as an area which has been sutured or is
otherwise recovering from injury or surgery. Contact with a sutured
healing area can also cause irritation, lengthen healing time and
prevent contact with air that promotes healing. The supportive
device is also designed to relieve pressure on a person's
vertebrae.
[0019] A person recovering from back surgery must be able to sit or
lie in a back resting position without having pressure against the
surgically recovering portion of the vertebrae. This is important
for people recuperating at home and can be particularly important
for persons who have returned to work and perform desk work such as
secretaries, draftsmen, and the like whose seating arrangements
would otherwise press against the back area where surgery has been
performed. The supportive device or portable belt is adjustable to
adjust the tension without removing or unfastening the belt. This
is very helpful in that it permits frequent adjustment to maintain
an acceptable level of comfort for the user.
[0020] The present invention provides a portable support device
which may be used to provide acceptable support and comfort for a
person while seated or lying down.
[0021] An optional feature is to provide a back support device that
relieves compressive forces on the vertebrae.
[0022] A further additional feature is providing a sleep garment
which protects a portion of a person's back (having stitches, etc.)
from pressures and contact with different objects encountered when
lying prone and turning while asleep.
[0023] Yet another aspect of the invention is that it allows
mobility for persons recovering from, for example, spine surgery
whereby they are able to use mass transit, their own personal
automobile, etc. so as to be able to lean back against a seat or
other support without pressure on, or contact with, portions of the
person's back side.
[0024] The device also provides hot or cold pressure to assist in
recovery from back surgery or to relieve back discomfort.
[0025] As seen in FIG. 1 of the drawing there is shown an
adjustable portable belt device 1 having three generally vertically
extending panels 7, 8, 9. The adjustable portable belt device 1 has
as elastic belt or belt portion 2 and an elastic belt or belt
portion 3. Belts 2 and 3 may be portions of the same monolithic
piece of elastic (as best seen in FIG. 1) or they may be separate
pieces joined together (as best seen in FIGS. 4-7). In the
embodiment of FIG. 4 panels 7, 8, 9 are one piece with separate
belts 2, 3 joined at the ends. In the embodiment of FIG. 7, elastic
belt 2 is removably connected to panel 7, panel 7 is removably
connected to panel 8 and panel 8 is removably connected to panel 9.
In the present drawings, line 24 (see especially FIG. 1) depicts
the belt device length direction and line 25 depicts the belt
device width direction.
[0026] Panel 9 is removably connected to elastic belt 3. In one
preferred embodiment each elastic belt portion 2, 3 is made out of
a typically light-weight but strong elastic fabric 11 with loops 12
(in the drawings the loops are distributed over the surface of
fabric 11) or other similar connectors on one side. Preferably the
elastic fabric 11 is severable by a conventional household scissors
or other similar cutting device so as to permit either, or both,
belt portions 2 and 3 to be cut to a desired length. This will
permit a user to be able to connect the desired number of panels to
belts 2 and 3 then cut excess length from the belt end(s) so that
each time the belt device 1 is used it will be of the correct
relative length without too much excess length.
[0027] One end of belt portion 3 has a belt fastener 6 (FIG. 4).
Fastener 6 is a section of fabric with hooks 13 or other similar
type connectors on one side. Fastener 6 may be removable or
permanently affixed to the belt 2, 3. As is evident from FIGS. 5
and 6 the belt may be wrapped around the desired body area and
joined by fastener 6 which overlaps the end portion 23 of belt
portion 3 and the end 22 of belt portion 2. One end of fastener 6
is attached to one end of belt 3 (as shown in FIGS. 4 and 5) and
the opposite end of fastener 6 is attached to any portion of the
belt 2 from the end 22 up to a panel (7, 8, or 9) so as to firmly
attach the belt to the desired part of the person's body. When the
belt device 1 is wrapped around the body the elastic belts 2, 3 are
stretched as desired by the user to firmly secure the belt and
apply a comfortable amount of tension on the belt 2, 3.
[0028] Belt device 1 has elastic straps 4, 5 for additionally
adjusting the tension in belt device 1. Two elastic straps are
shown, however, fewer or more such straps may be provided. One end
of strap 5 may be fixed to the belt 3 at or near to its connection
with panel 9 or as seen in FIG. 1 at or near panel 8. Elastic strap
5 can be stretched and then joined to underlying belt 3 thereby
adding tension to the belt 3 and thus, to the belt device 1. Hook
type fasteners 113 on one side of strap 5 are used to releasably
join to the loops shown on the substantially on the entire surface
of stretched belt 3 to maintain the belt 3 and belt device 1 in the
position with the additionally applied tension from strap 5.
Further belt device tension may be applied by stretching elastic
strap 4 and then joining it to belt 2 thereby adding the additional
tension in stretched strap 4 to belt 2. Thus, belt device 1 has
tension from belts 2, 3 and additional tension from each of straps
4, 5. In an alternative embodiment straps 4 and 5 may comprise an
elastic member with strap fastener 10 at one end as seen in FIGS. 4
and 5. Strap fastener 10 is like belt fastener 6 in that strap
fastener 10 is a section of fabric with hooks 213 or other similar
type connectors on one side. Fastener 10 may be removable or
permanently affixed to the strap 4, 5. As is evident from FIG. 1
the strap fastener 10 may be joined to overlap one end of strap 5
and a portion of belt 3. One end of strap fastener 10 is attached
at or near one end of belt 3 (as shown in FIG. 6) and the opposite
end of strap fastener 10 is attached to any portion of the belt 3
so as to add tension to belt 3 and adjust belt device 1 as desired
by the user. When using strap fasteners 10 the strap 4, 5 may or
may not have loops 113 as desired.
[0029] It should be evident that while hooks are described on one
surface and loops are described on a connecting surface, replacing
the hooks with loops and the loops with hooks is also
contemplated.
[0030] In a preferred embodiment straps 4 and 5, like belts 2 and 3
comprise an elastic sheet of fabric with hook or loop type
fasteners affixed to one surface. In this manner a strap fastener
10 with hook 213 type fasteners on its underside (as seen in FIG.
7) can be attached to the top side (as seen in FIG. 1) of strap 5
and to the top side (as seen in FIG. 7) of belt 3. The same is true
for strap 4 and belt 2.
[0031] Belt device 1 may include a plurality of panels 7, 8, 9. The
number of panels and their arrangement may vary depending on the
body area to be covered. The panels may be sewn together or
releasably fastened together. In the construction shown in FIG. 1
the center panel 8 is generally air permeable so that air can
promote healing of the affected area. The center panel 8 is made of
one layer of thin mesh-like material 30 (FIG. 4) and a backing
layer 31 with an opening 14. Opening 14 is large enough to surround
a prescribed area of a person's anatomy to protect that area from
pressure. In panel 8 a space is provided between the mesh-like
material 30 and the backing layer 31 area for insertion and removal
of an absorbent pad or dressing (not shown). The absorbent pad or
dressing may reside between the mesh material 30 and the persons
body by being hung on the mesh or provided on the person by being
affixed (taped, etc.) to the person over the sutured incision. The
mesh-like layer 30 loosely supports the absorbent pad or dressing.
The backing layer 31 takes the tension on the belt device through
the panel 8 so that the mesh-like material 30 can loosely fit over
the panel 8, supports any pad or dressing, but will not press
against the underlying prescribed area. In panels 7, 9 a space or
pocket is provided between the mesh-like material 30 and the
backing layer 31 for insertion and removal of a removable pack 32
(FIG. 2) of a hot or cold temperature retaining material for
applying therapeutic thermal treatment. The panels 7 and 9 (FIG. 2)
on either side of the center panel 8 (FIG. 3) have a thickness of
1/2 inch to three inches greater than the thickness of the center
panel 8. All of the panels need not be of the same thickness and
the thickness difference between panel 8 and, for example, panel 7
may reside in a pack 32 in the pocket of the panel 7. One edge of
mesh-like material 30 may be releasably fixed by a pocket fastener
33 (as by a snap, button/hole, hook and loop, etc.) to panel 7, 8,
9 to permit insertion and removal of pack 32 into the pocket 34. It
being understood that the other edges of the mesh-like material 30
are releasably or permanently fixed to the backing 31 along the
periphery of the panels 7, 8, 9. For example, the mesh portion of
center panel 8 may be removable fixed (as by hook and loop
fasteners, buttons, snaps, etc.) to permit removal of the mesh to
gain access to a bandage for cleaning of a wound and application of
a clean bandage. The mesh portion may be fixed to panels 7 and 9 by
being sewn to permanently fix the mesh to the panel.
[0032] The pockets 34 may be filled with an inflatable bag, with
foam rubber as well as provided with a hot/cold gel pack 32. A
suitable gel thermal pack that may be heated or cooled is described
in U.S. Pat. No. 4,756,311. The panels 7, 8, 9 and pockets 34 may
vary in shape, size and number.
[0033] When the belt device 1 is placed on a persons back such that
the center panel 8 overlies the vertebrae the thickness of the
adjacent panels 7, 9 prevents pressure on the center panel area
when the person is seated or lying down. The pressure against the
persons back is against the thicker side panels 7, 9, not the
portion of their back covered by the thinner center panel 8. Thus
the center panel 8 will cover an incision area while at the same
time avoiding pressure being applied to the incision area. The
difference in thickness between the center 8 and adjacent panels 7,
9 is great enough to permit a dressing to cover the sutured area
without pressure.
[0034] As described above, when the adjustable belt device 1 is
firmly affixed to a person's torso the panels 7, 8, 9 support the
back or lumbar region so as to apply decompressive forces to the
vertebrae. Stays or stiffeners 15 maintain the width of the belt
and enhance this effect. Rigid stays 15 may be contoured to provide
better support and comfort to the back or other body portion. As
seen in for example FIG. 2, stay or stiffener 15 is held in place
in a pocket of the belt device 1. Such pockets (shown in each of
FIGS. 1-7) confine the contoured stiffener 15 to the desired
location so as to advantageously apply pressure to the underlying
body area. Stays or stiffeners 15 may be removed from the pockets
to prevent support in an undesirable area. Removal of one or more
stays 15 softens the feel of the belt device for the user and thus
provides a greater range of comfort and support. The stays 15 may
be retained in the pockets with or without a pocket fastener, like
pocket fastener 33.
[0035] As best seen in FIG. 1, belt device 1 is shaped to accept
tensional loading but not compression loading. Belts 2, 3 are
elastic fabric which permits the panels to be stretched apart along
length axis 24 so that the belt device is stretched taut (absorbs
tensional loading) while the panel 8 has opening 14 to allow air
circulation (FIG. 3) and prevent the application of pressure (does
not permit compression) to that area of the person's anatomy.
[0036] Although the present invention has been described and
illustrated in detail, it is to be clearly understood that the same
is by way of illustration and example only, and is not to be taken
by way of limitation. The spirit and scope of the present invention
are to be limited only by the terms of the appended claims.
