Description
BACKGROUND OF THE INVENTION
A relatively frequent complication following the birth of a baby is
an edema in the treatment of which ice packs are commonly used. Ice
packs are also used to prevent an edemitous condition from arising.
Ice packs, as the treatment is now practiced, are separate from the
perineal pads that are then worn. As the ice packs are too
expensive to be regarded as disposable and as their application
entails extra work on the part of the nurses and results in a bulky
arrangement that in practice prevents the patient from being
ambulatory, there is a need for a perineal pad of simple, low cost
construction ensuring sterility, ease of application, and patient
comfort when the use of a cold pack is indicated.
THE PRESENT INVENTION
A principal objective of the present invention is, accordingly, the
provision of perineal pads that meet the requirement of production
and use, an objective attained with a pad for use with a separate
thermal pack in providing thermal treatment of the urogential
region of the perineum, the pad comprising a flexible member with
an absorbent member carried thereby, and means for attaching the
pack to the flexible member in a position to underlie that portion
of the absorbent member that is to be in engagement with the
urogential region of the perineum.
Another objective of the invention is to ensure sterility of the
pad while it is being prepared for use, an objective attained by
providing that the pad comprises an elongated gauze sleeve open at
one end and a sterile absorbent member within the central portion
of the sleeve, one surface of the central portion to be disposed in
engagement with the urogential region of the perineum. The ends of
the sleeve are of a length providing forward and rearward attaching
portions by which the pad may be attached to a patient with said
one surface thus positioned. The forward attaching portion is the
open end of the sleeve. The pad, prior to use, is folded
transversely upon itself with respect to said one surface with a
fold line between the ends of the absorbent member but spaced from
the forward end thereof to define, at least when the pad is thus
folded, the bottom of a pocket between the sleeve and the other
surface of the absorbent member accessible through the open end of
the sleeve. The free end of the rearward attaching portion is
folded over said one surface and is dimensioned so that its free
end extends to the forward end of the absorbent member thus
enabling the folded pad to be handled without said one surface
losing its sterility while a thermal pack is being entered into the
pocket through the forward attaching portion.
Another objective of the invention is to provide a pad in which the
forward attaching portion is divided along its side to provide
separable flaps, one foldable against the free end of the rearward
attaching portion and the other foldable against said other pad
surface while the thermal pack is being inserted.
A further objective of the invention is to provide a perineal pad
which, when the pack is attached thereto for use maintains the
absorbent member concave, lengthwise considered, with respect to
its surface that is to be in engagement with the urogenital region,
an objective attained by providing, in the case of a non-frozen
pack, a concave backing therefor and in the case of a frozen pack,
providing the frozen pack with a concave surface.
Another objective of the invention is to provide a perineal pad in
which the absorbent member includes a portion extending rearwardly
of that part that is to engage the urogenital region and there
being of increased thickness.
Yet another objective of the invention is to provide a perineal pad
in which the absorbent member includes marginal portions to overlie
the sides of the thermal pack.

THE PREFERRED EMBODIMENT OF THE INVENTION
The perineal pad illustrated by the drawings comprises an elongated
flexible member 15, preferably a gauze sheet, with its margins
folded to overlap centrally of the outer surface of the pad and
secured together in a suitable manner, preferably by an adhesive to
provide a sleeve. An absorbent member generally indicated at 16 is
encased in the flexible sleeve member 15 between the ends thereof
so that said ends provide forward and rearward attaching portions
indicated, respectively, at 15A and 15B by which the pad may be
detachably secured to a belt. The absorbent member 16 is shown, see
FIG. 6 as comprising a bat-like fibre body 17, an outer layer 18
that is preferably moisture resistant and that has its margins
overlapping and adhesively secured to the margins of an absorbent
layer 19 on the surface of the body 17 that is to engage the
urogenital region of the perineum and hereinafter referred to as
the inner surface of the pad.
In accordance with the invention, the absorbent member 16 includes
a posterior portion 16A of increased thickness, conveniently a
doubled-over end. The forward attaching portion 15A of the flexible
sleeve member is divided into inner and outer flaps, see FIGS. 5
and 9, to enable a thermal pack generally indicated at 20, to be
inserted between the absorbent member 16 and the outer face of the
flexible sleeve member 15. The thermal pack 20 is discussed herein
as an ice pack.
The pad is shown in FIGS. 1 and 2 folded transversely at the
junction of the absorbent member 16 and its thicker portion 16A
enabling the attaching portion 15B to overlie the otherwise exposed
inner surface of the absorbent member. The attaching portion 15A is
folded over the attaching portion 15B. In practice, the thus folded
pad would be within a protective envelope until its use was wanted.
The pad, when removed from its envelope may be readied for use
without loss of sterility of the inner face thereof by holding it
in its unfolded state with the attaching portion 15B overlying said
inner face. The outer flap of the attaching portion 15A is then
folded downwardly against the other face of the pad facilitating
the entry of the pack 20 between the flaps of the forward attaching
portion 15A and into the pocket defined by the outer face of the
absorbent member 16, the outer face of the sleeve member 15 and the
fold line established by the folded over portion 16A of the
absorbent member. With the pack 20 in place, the pad is then
unfolded and its end portion attached to the belt.
It will be noted that the absorbent member 16 is shown with its
margins 16C folded to define pocket sides receiving between them
the sides or edges of the pack 20. This construction is preferred
when the presence of an ice pack would otherwise be uncomfortably
cold to the patient.
The pack is shown as a bag having a neck 20A with lengthwise folds
20B extending lengthwise of its sides enabling the bag to expand as
it is filled. After the bag is filled, the neck 20A is then folded
over and securely closed by means of a wrap-around 21 of the type
including a bendable non-resilient wire 21A secured to one face of
the neck 20A near its mouth enabling the folded over portion to be
quickly and easily secured. The bag is formed of thin waterproof
plastic stock to be so inexpensive that it may be discarded after a
single use.
In use, the packs may be filled with crushed ice or they may be
water filled and then frozen. It is preferred, however, that the
inner surface of the absorbent member 16 be concave. It is
preferred that the bags are filled with water and then placed on a
convex form 22, see FIG. 10, in a freezer, not shown, thus to
provide the frozen bags with the desired concave form. When the
contents of the bags are not frozen as when they are filled with
crushed ice, an appropriately shaped backer 23 is inserted between
the pack and the outer surface of the flexible sleeve member 15,
see FIG. 11.
