Description
BACKGROUND OF THE INVENTION
This invention relates to self-adhesive surgical apparel and, in
particular, to self-adhesive disposable surgical drapes and towels,
and, more particularly to means for conveniently securing the same
to a patient.
Surgical drapes and towels are used to cover a patient and
operating table during surgery in order to provide a sterile field
and to prevent contamination of the region of the patient on which
the operation is to be performed. In order to serve this function,
drapes and towels must be impervious to penetration by liquids and
microorganisms. In addition, they should not be subject to slipping
or moving about relative to the operative site on the patient after
having been placed on the patient in the arrangement desired by the
surgeon. Otherwise, bacteria from the patient's own body could be
transferred to (and contaminate) the site of the incision by the
underside of the drape or towel. Also, such undesired slipping
could interfere with and delay an operative procedure.
The prior art development of attachment means for surgical drapes
and towels has taken two main approaches. The first of these
approaches, which has long been used in the surgical art, is the
use of clips to fasten drapes or towels together. The use of
surgical clips as attachment means for surgical drapes and towels
has the disadvantage that the clips may not only damage the drapes
and towels, thereby destroying the sterile field, but may also
injure the patient.
To overcome the disadvantages which follow from the use of clips as
attachment means, a second approach to the attachment of surgical
drapes and towels to a patient has been taken. This approach
involves the use of pressure-sensitive adhesive on the undersides
of disposable surgical drapes and towels, that is, the sides in
contact with or closest to the patient's body when in use. The use
of pressure-sensitive adhesive as an attachment means substantially
eliminates the possibility of damage both to drapes and towels and
to the patient. However, the prior art use of pressure-sensitive
adhesive on the undersides of surgical drapes and towels has itself
caused a further difficulty.
Thus, releasable cover sheets are generally placed over the
adhesive to prevent undesired adhesion thereof prior to use of the
drape or towel, and the surgeon or nurse must remove these cover
sheets prior to attaching the drape or towel to a patient. The
location of the adhesive on the underside of the drape or towel,
combined with the necessity for removal of the releasable cover
sheet prior to use thereof, results in either lack of accurate
placement or difficulty of attachment of the drape or towel, as
will be described in more detail below.
Self-adhesive surgical drapes of the prior art may be arranged over
and secured to a patient by one of two procedures. On the one hand,
the cover sheets may be removed and the prior art self-adhesive
drape may be attached to the patient prior to the unfolding
thereof. If such a procedure is followed, then inaccurate or
incomplete draping may result when the drape is unfolded. No
adjustment of the position of the drape is possible subsequent to
unfolding, because attachment has already been effected.
On the other hand, the cover sheets may be removed and the
self-adhesive prior art drape may be attached to the patient after
the drape has been unfolded and properly positioned on the patient.
Such a procedure allows correct positioning of the unfolded drape,
but makes attachment inconvenient and difficult, particularly
without endangering the sterile field which has just been created
by the draping procedure. Thus, to remove the cover sheets of the
prior art self-adhesive drape after unfolding the same, the surgeon
must grope under the drape to find the adhesive and must then
remove the cover sheets therefrom. This is difficult to do without
disturbing the drape or distrupting the sterile field. Such a
procedure is inconvenient and risks contamination.
Prior art self-adhesive towels are attached by similar procedures
and suffer from similar difficulties, although not to the same
degree as prior art self-adhesive drapes.
SUMMARY OF THE INVENTION
There is provided by my invention pressure-sensitive adhesive
securing means for surgical drapes and towels whereby they may be
unfolded and arranged over a patient prior to attaching said towels
or drapes thereto, without incurring the inconvenience and risk of
contamination necessitated by the pressure-sensitive adhesive
attachment means of the prior art. The present invention comprises
a surgical drape or towel, preferably of the disposable type, which
has at least one foldable flap integral with an edge thereof, this
flap having pressure-sensitive adhesive on at least part of one
surface thereof and a releasable cover sheet overlying said
adhesive. The flap is so disposed on the unused drape or towel as
to present the covered adhesive away from the body of the patient
while positioning the drape or towel, whereby the releasable cover
sheet can be readily removed from the adhesive without disturbing
the drape or towels; and the flap is foldable whereby to present
the uncovered adhesive toward the body of the patient for
attachment of the drape or towel thereto, again without disturbing
the arrangement thereof or risking contamination of the sterile
field. The edge with which said flap is integral can be an external
edge, as the edge of a surgical towel, or an internal edge, as the
edge of a fenestration opening of a surgical drape.
In using the self-adhesive surgical drape or towel of my invention,
it is arranged over a patient with the flap positioned so that the
covered adhesive is presented away from the patient. The releasable
cover sheet is then removed, and the flap is folded so that the
uncovered adhesive is presented toward the patient for attachment
of the drape thereto.
The disposable self-adhesive drapes and towels of my invention may
be of any conventional construction and may be made of materials
conventionally employed therefor. For example, they may be
constructed of such liquid--and bacteria--impervious material as
plastic film and treated nonwoven fabrics. Suitable films include
polypropylene, polyethylene and polyvinyl chloride films. A
preferred material of construction is adhesive-bonded, wet-laid
nonwoven fabric formed from nylon and cellulosic fibers and treated
to impart water repellency thereto. Of course, where desired,
absorbent materials may also be employed.
Any conventional pressure-sensitive adhesive may be used in the
practice of my invention, as for example, known polyacrylate or
polymethacrylate pressure-sensitive adhesives formulated for
contact with the skin without adverse side effects for the
anticipated duration of use.
The releasable cover sheet used in my invention may be of any
conventional material commonly used as release paper, for example,
silicone-coated or wax coated paper.
In one embodiment of the drape of my invention, the
pressure-sensitive adhesive is located on the upper surface of the
flap, which is folded under the drape to present the uncovered
adhesive toward the body of the patient for attachment of the drape
thereto, after proper placement of the drape over the patient and
removal of the releasable cover sheet from the adhesive.
In a second and preferred embodiment of a drape in accordance with
my invention, the adhesive is located on the lower surface of the
flap, which is folded up to present the covered adhesive away from
the body of the patient, for removal of the releasable cover sheet
therefrom after proper placement of the drape, and is then unfolded
to present the uncovered adhesive toward the body of the patient
for attachment of the drape thereto.
The same embodiments are possible with towels. That is, the
adhesive may be located on either the upper surface or the lower
surface of the towel on a flap integral with an edge of the towel.
In either embodiment, the towel is first placed in position, the
flap of the towel being positioned so that the covered adhesive is
presented away from the body of the patient, the releasable cover
sheet is removed, and the flap is then folded so that the uncovered
adhesive is presented toward the body of the patient for attachment
of the towel thereto (or to a previously positioned drape or
towel).
My invention will be more clearly understood by referring to the
attached drawings, which show illustrative embodiments thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring specifically to FIGS. 1-4, there is illustrated a
surgical drape 1 having a fenestration opening 2 of generally
rectangular configuration. Integral with a pair of opposed edges of
the fenestration opening are flaps 3 which normally extend into the
opening. Flaps 3 are of generally trapezoidal configuration, as
illustrated, for ease of folding in use, but may be of any desired
configuration, such as a generally rectangular configuration. On at
least part of upper surfaces 4 of flaps 3 there is
pressure-sensitive adhesive 5 covered with releasable cover sheets
6. Flaps 3 are foldable along fold lines 7 so that they may be
folded under the drape to present the uncovered pressure-sensitive
adhesive 5 to the body of patient 8 after placement of the drape on
the patient and removal of the releasable cover sheets. As shown in
FIG. 4, when flaps 3 are so folded, fenestration opening 2 is
enlarged to the full size intended for use.
The removal of cover sheets 6 is shown in the enlarged view of FIG.
2. FIG. 3 shows the adhesive-coated flaps, with the release paper
removed, preparatory to folding the same under the drape. FIG. 4
shows the flaps of FIG. 3, folded under the drape to present the
same toward the body of the patient for attachment of the drape
thereto.
In FIGS. 5-7, the same reference numerals are used as for the
embodiment illustrated in FIGS. 1-4 to designate the same parts. As
shown, surgical drape 1 of this embodiment has a fenestration
opening 2 of generally rectangular configuration, and four flaps 3,
each flap being integral with one of the four edges of the opening,
and extending into the opening. Flaps 3 may be of generally
trapezoidal configuration, as illustrated herein, or may be of
generally rectangular configuration, but preferably do not overlap.
In this embodiment of the invention, the four flaps about the
fenestration opening provide enhanced attachment of the drape to
the body of the patient in the area of the fenestration. As in the
embodiment of FIGS. 1-4, there is pressure-sensitive adhesive 5 on
at least part of the upper surfaces 4 of flaps 3. In storage, the
pressure-sensitive adhesive is covered by releasable cover sheets
6. The flaps are foldable along lines 7 so that they may be folded
under the drape after removal of the releasable cover sheets from
the adhesive, so as to present the same toward the body of the
patient for attachment of the drape thereto. In FIG. 7 the flaps
have been folded under the drape to present the uncovered
pressure-sensitive adhesive toward the body of the patient for
attachment of the drape thereto.
In FIGS. 8-10, there is illustrated the fenestration area of the
presently preferred embodiment of a surgical drape in accordance
with the present invention. As shown, surgical drape 10 has a
fenestration opening 11 of generally rectangular configuration, and
a pair of rectangular flaps 12, each integral with one of a pair of
opposed edges of said opening. On at least part of the upper
surfaces 13 of flaps 12, as best seen in FIG. 9, there is
pressure-sensitive adhesive 14 covered with releasable cover sheets
15. The flaps are foldable along lines 16. Normally the flaps are
folded back on top of the drape to present the covered adhesive
away from the body of the patient. In using this preferred
embodiment of my invention, the flaps are unfolded, after removal
of the cover sheets, to present uncovered pressure-sensitive
adhesive 14 to the body of the patient for attachment of the drape
thereto. As shown in FIG. 10 this unfolding of the flaps decreases
the area of the fenestration opening to the size intended for
use.
Referring to FIGS. 11 and 12, there is illustrated a surgical towel
20 of generally rectangular configuration embodying the present
invention, towel 20 having a foldable flap 21 at one end thereof.
On at least part of upper surface 22 of the flap there is
pressure-sensitive adhesive 23 covered with releasable cover sheet
24. The towel of this embodiment of the invention is folded along
lines 25 and 26 so as to present covered adhesive 23 away from the
body of the patient. In use, the towel is positioned on a patient,
cover sheet 24 is removed from the adhesive, and towel 20 is folded
along line 25 so as to present the uncovered adhesive 23 of flap 21
towards the body of the patient for attachment of the towel thereto
or to a previously positioned towel or drape.
In FIGS. 13 and 14, there is illustrated the presently preferred
embodiment of a towel in accordance with my invention, a surgical
towel 30 of generally rectangular configuration having a foldable
flap 31 at one end thereof. On at least a part of lower surface 32
of the flap (as seen in FIG. 14) there is pressure-sensitive
adhesive 33 covered with releasable cover sheet 34 (FIG. 13).
Normally, the flap is folded along line 35 so as to present the
covered adhesive away from the patient. In use, the towel is
positioned on a patient, the cover sheet is removed from the
adhesive, and the flap is unfolded so as to present the uncovered
pressure-sensitive adhesive toward the body of the patient for
securing of the towel.
While several specific embodiments of the invention have been
described with particularity, they are provided for purpose of
illustration, and many variations and modifications may be made
without departing from the spirit and scope of the invention. Thus,
for example, while the drapes, towels and flaps of the invention
have been illustrated as being generally rectangular in
configuration, other configurations could be employed. Similarly,
it is not necessary that pairs of tabs be employed around the
fenestration, the use of one or three flaps, for example, being
within the scope of the invention.
