Description
A WRAP AND A WRAPPING METHOD
Technical Field
The invention relates to a wrap and a wrapping method, and in particular, a wrap and
a wrapping method which can be used to wrap medical procedure trays.
Background Art
Any reference herein to prior art is not intended to imply that such prior art forms or
formed a part of the common general knowledge in Australia or any other country.
Presently, medical procedure trays (otherwise known as MPTs) are used in various
procedures in hospitals, clinics, and even for home nurse care when sterile
equipment is required for a medical procedure.
MPT’s are typically characterised into two distinct technical clinical procedure levels:
standard ANTT (aseptic non-touch technique) and surgical ANTT.
Standard ANTT procedures are technically simple procedures with a typically short
term duration (approximately less than 20 minutes). Such procedures can typically
include: IV (intravenous) Therapy, simple wound dressings, urinary catherisation and
cannulation. MPT’s for these procedures generally rely on “manually” outer wrapping
of the trays.
Surgical ANTT procedures are technically more complex procedures, and involve
extended periods of time. Such procedures often include complex or large wound
dressings, PICC/CVC (periphery inserted central catheter/central venous catheter)
insertion and surgery. MPT’s for these procedures generally have a higher level of
automated wrapping and packaging.
Typically, both levels of ANTT are required to be performed utilising a “sterile field”
which in most cases is the outer wrapping of the MPT’s.
For these procedures, and in order to satisfy health and safety guidelines, medical
staff have to go through great lengths to ensure that the equipment included in MPT’s
is delivered onto the sterile field in a manner that maintains sterility of all the
components.
However, for all ANTT procedures (as examples detailed above) this has been an
ongoing issue around the world for many years.
All MPT’s manufactured for standard ANTT procedures utilising a sterile field outer
wrapping are by necessity manually packed. Furthermore, the various types and
styles of manually wrapping the outer sterile fields have required exposed flaps or
tabs to be left protruding or accessible for the medical staff to unfold the outer wrap
easily and quickly.
The flaps or tabs have been a great cause of concern as they can contaminate the
sterile field by the simple action of grabbing the tabs with non-gloved hand/fingers or
by the delivering of the MPT (from the outer pouch/pack) onto a non-sterile surface
where the exposed flap or tab can touch the surface.
Summary of Invention
In one form, there is provided herein a method for wrapping a tray, the method
including the steps of: placing the tray on a wrap; folding the wrap such that the wrap
forms a triangular portion, the triangular portion encasing the tray therein; folding a
first corner of the triangular portion towards the tray; folding a second corner of the
triangular portion towards the first corner such that folding of the first corner and the
second corner form a pocket; and, folding a third corner of the triangular portion into
the pocket such that the tray is wrapped therein.
In one example, folding the first corner and the second corner towards the tray
includes: folding the first corner at a first parallel line to a height of the triangle,
forming a first folded edge; and, folding the second corner at a second parallel line to
the height of the triangle, forming a second folded edge.
In yet a further example, the method further includes, forming the pocket by folding,
at a first side edge of the tray, the first folded edge towards the tray; and, folding, at a
second side edge of the tray, the second folded edge towards the tray.
According to a further form, the wrap has a quadrilateral shape, and folding the wrap
to form the triangular portion provides a base triangular portion and an overlaying
triangular portion, the tray being encased between the base triangular portion and the
overlaying triangular portion.
In yet another example, a height of the base triangular portion is greater than a
height of the overlaying triangular portion.
According to yet another example, the height of the base triangular portion is greater
than the height of the overlaying triangular portion by 1 to 6cm for a 50cm x 50cm
wrap.
In yet a further form, the method includes placing the tray on the wrap, where a half-
way line of the tray is substantially aligned with a height line of the triangular portion,
and the method further includes folding the first corner towards the tray such that the
first corner extends past the half-way line of the tray.
According to another example, the method includes folding a second corner of the
triangular portion towards the first corner such that the second corner extends past
the half-way line of the tray.
In yet a further example, there is provided herein a wrap, the wrap being configured
to wrap a tray, such as an MPT tray or the like, in accordance with the methods
described herein.
It will be appreciated that any of the features described herein can be used in any
combination.
Brief Description of Drawings
A specific embodiment of the invention will now be described below with reference to
the accompanying drawings in which:
Figure 1 is a top view of an example of a wrap for wrapping a tray; and,
Figures 2 to 7 are top views of example steps for wrapping the tray of Figure 1.
Description of Embodiments
There is provided herein a wrap and a method for wrapping. In one particular
example, the wrap and the method for wrapping can be used to wrap trays, and
particularly, MPTs.
Figure 1 shows an example of a tray 10 placed on a wrap 20. In this particular
example, the wrap 20 is quadrilateral in shape, and in particular, square in shape.
The wrap typically has a sterile side 25 and an outer side 30 (shown in Figure 2).
Typically, the outer side 30 is placed down on a table or the like, for wrapping the tray
10, which is placed on the sterile side 25.
As shown in Figure 2, the wrap 20 can be folded such that the wrap 20 forms a
triangular portion 35, where the triangular portion 35 can encase the tray 10 therein.
In the example shown in Figure 2, a base corner 40 is picked up and folded towards
a top corner 42. Thus, the wrap is typically moved along a bottom edge of the tray,
and folded upward towards the top corner 42.
Thus, for example, the tray 10 can have a half-way line 45, which is typically the line
from top to bottom of the tray 10, and is typically at half-way of the width of the tray
. The tray 10 can be positioned in the wrap 20 such that the half-way line 45 of the
tray 10 is substantially aligned with a height line 55 of the triangular portion 35. The
height line 55 is typically a line from the base 60 of the triangular portion 35 to the top
corner 42.
As shown in the example of Figure 2, folding the wrap to form the triangular portion
can provide a base triangular portion 32 and an overlaying triangular portion 34,
the tray 10 being encased between the base triangular portion 32 and the overlaying
triangular portion 34.
Typically, a height of the base triangular portion is greater than a height of the
overlaying triangular portion. Thus for example, for a 50cm x 50cm wrap, the height
of the base triangular portion can be greater than the height of the overlaying
triangular portion by 1 to 6cm for a 50cm x 50cm wrap. Accordingly, the heights and
widths of the triangular portions can be different to allow for only one leading edge of
a corner to be prominent. In the examples herein, the corner 42, for example is a
leading corner. It will be appreciated that this can allow for the reduction of initial
tabs or edges by 50%, for the early folding process. When secondary folding is
undertaken, only one leading edge is needed to secure the fold (such as the corner
42, as discussed below), which can thus minimise exposed leading edges or tabs.
In the example shown in Figure 3, a first corner 50 of the triangular portion 35 is
folded towards the tray 10, such that the first corner 50 extends past the half-way line
45. Typically, the first corner 50 extends at least ¾ of the width of the tray. Thus, for
example, in a 50cm x 50cm wrap, the distance between the first corner 50 and the
half-way line 45 may be around 2cm to 3cm. In the example shown in Figure 3, the
first corner 50 is the corner on the left hand side of the wrap. Thus, in performing this
step, a user may hold down the wrap 20 with their right hand, and using their left
hand pick up the wrap at A, and fold to the right until the corner A exceeds the half-
way line 45.
Figure 4 shows an example of where the wrapping method described herein further
includes folding second corner 52 of the triangular portion 35 towards the first corner
50 such that the second corner 52 exceeds past the half-way line 45 of the tray 10.
Thus, in the example as shown in Figure 4, a user may hold down the corner A with
their left hand, and using their right hand, pick up the corner B and fold towards the
left until corner B exceeds past the half-way line 45 of the tray 10. Notably, corner A
is kept flat against the tray 10.
Folding of the first corner 50 at a first parallel line 60 to the height line 55 of the
triangular portion 35 can form a first fold edge 62. Similarly, folding and the second
corner 52 can at a second parallel line 65, which is parallel to the height line 55, form
a second folded edge 68.
Figure 5 shows an example of the folding method described herein further including
folding of the first folded edge 62 towards the tray 10, where the fold occurs at a first
side edge 72 of the tray. Similarly, Figure 6 shows an example of folding of the
second folded edge 68 towards the tray 10, where the fold occurs at a second side
edge 74 of the tray 10.
Accordingly, in performing the steps shown in Figures 5 and 6, a user may hold down
corner B with their right hand, and using their left hand, pick up the wrap at S1 along
the left edge of the tray to fold until S1 covers the corner B. Corner B is typically kept
flat. Then, the user can hold the wrap at S1 down with their left hand, and using their
right hand, pick up the wrap at S2, and along the right edge of the tray, fold until the
wrap covers S1.
Thus, the folding of the first corner 50 and the second corner 55, either independently
or together with the folding of the first and second edges 62, 68 can create or form a
pocket 80.
In this particular example, the top of the tray 10 is typically about half way up S1 and
S2 such that the pocket 80 is folded in half and the corner 42 is folded into the base
of S1 and S2, thus enclosing the entire wrapped tray. The corner C (also noted
herein as the corner 42) is thus formed inside the base folding.
As shown in Figure 7, a third corner of the triangular portion 35 (which in this
example is the corner 42) is folded into the pocket 80 such that the tray 10 is
wrapped therein. Typically in this step, the tray is flipped up and the corner C is
folded down into the wrap
It will be appreciated once the tray 10 has been wrapped, the wrapped tray can
undergo terminated sterilisation, or other sterilisation procedures. Thus, for example,
once the tray is completely wrapped, the wrapped tray can be placed into an outer
pouch (either a paper/plastic “peel pouch” which is heat sealed at the bottom or
alternatively, a full plastic “tera pouch” which is heat sealed. The completely sealed
pack is then thermally sterilised (Gamma, Eto – Ethelyne Oxide gas or other
internationally recognised sterilisation method) thus the packs are then typically
ready for use as a sterile MPT.
It will also be appreciated that the wrap and wrapping method described herein can
be applied to various shaped and sized trays and accordingly wraps.
Thus, for example, various shapes of trays can be provided, including and not limited
to square, rectangular, kidney shape and round. Typically, the shape of the wrapping
field is square and the dimensions of the wrap are typically determined by the sizing
of the trays.
It will further be appreciated that the wrapping which can be used is typically a
plastic film (such as, for example, polyethylene). However, it will also be appreciated
that many other types of material may also be possible, including but not limited to
paper, non-woven, woven, layered fibre, a composite material, and the like. Typically,
the type of wrapping may be chosen based on the purpose of the tray.
The examples of the wrap and wrapping method described herein can provide
numerous advantages, including, and not limited to:
providing a range of MPTs which are sterilised by a standard method, where the
method can provide a consistent way of wrapping MPTs which can provide
consistent sterilisation
a wrapping method which can eliminate the need to touch (by medical staff) the inner
sterile side of the MPT wrapping, or the need for the MPT wrapping to touch a non-
sterile surface
providing a wrapping method where any portion of the sterile side of the wrap does
not need to be touched during actual unfolding of the wrap
can reduce the incidence of HAI (Hospital Acquired Infections) associated with
ineffective delivery of MPT’s, which are meant to have high levels of sterility
Whilst there has been described herein a particular embodiment of a wrap and
wrapping method, the described embodiments are considered in all respects only as
illustrative and modifications can be made without departing from the spirit and scope
thereof.
