Abstract
A medical corset intended to limit chest expansion of a wearer. The corset consists of two side panels (103, 104) joinable at the front by a slide fastener and at the back by at least two adjustable fasteners (111). The two adjustable fasteners include indicia (114) or markings that allows the length to which they have been set to be visibly determinable. This allows easy determination of whether the corset has become maladjusted. The adjustment is intended to limit the chest expansion of the wearer and the slide fastener allows removing or donning the corset without changing the adjustment.

MEDICAL CORSET
Technical Field
The invention generally relates to medical corsets.
More particularly the invention relates to medical corsets for protecting the wearer
from undue chest expansion.
GLOSSARY
“FVC” Forced Vital Capacity is the amount of air which can be forcibly blown from
the lungs after a full inspiration.
Background Art
Medical corsets are known and are provided to persons who either require protection
or restriction from some body movement or require support which their body is no
longer able to provide. Some of these corsets are intended to protect a patient from
the effects of sternum separation or the separation of joints affected by rib surgery by
preventing expansion of the chest.
US 4508110 provides a rigid orthosis of two shells joined by lacings which are of
preset length and pulled tight once the orthosis is in place to adhere with Velcro
straps. While the spacing of the shells can be controlled there is no indication of the
“correct” adjustment.
US 4838263 shows a thoracic pneumatic vest which can provide thoracic pressure,
normally oscillatory. It is non-expansible and may have a hook and loop fastening at
the front or such fastenings at the sides. Again there is no indication of the correct
adjustment of the vest.
US 8500670 describes a vest for post-surgical use which has an adjustable band
encircling the chest. The band is stretchable and may be fastened by a hook and loop
fastening. Handles are supplied to allow the wearer to temporarily alter the encircling
force. No means of verifying the tension of the band is described.
US 20010034498 describes a harness including an adjustable chest expansion restraint
with front fastening and rear adjustment. The rear adjustment may be temporarily
206648NZ_CompSpec_V2_20200804.docx
tightened by the patient to cater for post-surgical coughs, sneezes etc. The degree of
tightening is not measured.
Such corsets are generally hard to put on and hard to adjust and it is difficult to
monitor patient compliance in wearing them.
Therefore a need exists for a solution to the problem of donning a corset and
preferably monitoring the wearers use of it.
The present invention provides a solution to this and other problems which offers
advantages over the prior art or which will at least provide the public with a useful
choice.
All references, including any patents or patent applications cited in this specification
are hereby incorporated by reference. No admission is made that any reference
constitutes prior art. The discussion of the references states what their authors assert,
and the applicants reserve the right to challenge the accuracy and pertinency of the
cited documents. It will be clearly understood that, although a number of prior art
publications are referred to herein, this reference does not constitute an admission that
any of these documents form part of the common general knowledge in the art in any
country.
Summary Of The Invention
In one exemplification the invention consists in a medical corset dimensioned to
substantially enclose at least a portion of at least the thoracic area of a person, the
medical corset having separable sides each with a rear edge, a top edge, a bottom edge
and a front edge such that each separable side of the medical corset when worn by a
person will cover at least a portion of the back of a person and extend forwards
around the rib cage on each side, coacting parts of a slide fastener or similar device
extending down each of the front edges of the medical corset and being fastenable to
each other; at least two adjustable length fasteners with cooperating parts, the
cooperating parts being mounted adjacent each of the rear edges such that the rear
edges of the medical corset are connectable by the adjustable length fasteners to be
adjustably spaced by the cooperating parts of the fasteners.
206648NZ_CompSpec_V2_20200804.docx
Preferably the adjustable length fasteners having graduations to provide length
indication.
Preferably the corset has a remotely readable data logger sensitive to at least the pulse
of a corset wearer located within the structure of the medical corset.
Preferably the slide fastener is a separable interengaging tooth fastener.
Preferably the adjustably spaced cooperating fasteners are fastened by a hook and
loop material,
Preferably the cooperating adjustable length fasteners may be fixed in length once
adjusted.
Preferably the data logger is additionally sensitive to the degree of expansion of the
chest of the wearer.
In a further exemplification the invention relates to a method of adjusting the fit of a
medical corset as claimed in claim 1 by calculating or measuring the maximum
expanded lung volume of a potential wearer, placing the medical corset on the
potential wearer, fastening the slide fastener and adjusting the cooperating adjustable
length straps to limit the wearers forced vital capacity (FVC) to less than 80% of the
expanded lung volume.
Preferably the lung volume is limited to less than 70% of the expanded lung volume.
These and other features of as well as advantages which characterise the present
invention will be apparent upon reading of the following detailed description and
review of the associated drawings.

Description of the Invention
Referring now to the drawing shows at 101 a person wearing the inventive
corset generally shown at 102 and consisting of two sides 103 and 104 which are
completely separable. Each side may have a supporting strap 106 but these are not
essential. Where provided they may be adjustable in length.
The sides have top edges 107, bottom edges 108, front edges 109 and rear edges ( 110. The front edges carry the cooperating parts of a slide fastener 105 which is
preferably an interlocking tooth fastener of the type in which one side is totally
separable from the other. Other types of slide fastener can be used, bearing in mind
that the aim of the fastener is to allow the wearer to remove the corset 102 without
changing any fitting adjustments and to put it on again without undue difficulty.
Typically the corset is in some tension even when the wearers chest is relaxed in order
to ensure that it does not exceed the maximum chosen lung inflation. This renders
fastenings such as buttons difficult to use and slide fasteners have the advantage that
they can be operated to open and close even under lateral tension.
shows a rear view of the corset when fitted, showing top edges 107, bottom
edges 108, rear edges 110 and several straps 111 which adjust the fit of the corset.
Flaps of material (not shown) may underlie both the slide fastener at the front and the
open area over which the straps 111 extend at the rear for the comfort of the wearer.
The corset may be made of any relatively non-stretching material, for instance nylon
mesh. The material used is preferably permeable, washable and non-shrinking and
may include a wicking component or lining to remove moisture from the skin.
Four straps 111 are shown but the actual number required will vary with the material
of the corset, for instance a semi-rigid corset of two shells might require only a top
and bottom adjustment strap while a corset of very light stretch resistant polyester
fabric might require six or seven. The straps are adjustable in length and the setting of
the adjustment is visibly determinable. This allows easy determination of whether the
corset has become maladjusted.
206648NZ_CompSpec_V2_20200804.docx
The number of straps will also vary with the length of the corset which may be chosen
to suit the wearers need and may vary from a corset covering only the upper ribs to
one covering the whole thorax and the upper part of the abdomen.
shows the adjusting straps of which have co-operating fastening parts
which include a pad 112 securely adhered or sewn to side 104 of the corset and
carrying a non-stretchable strap 113 which may have measurement indicia 114 on it to
assist in adjusting the fit, and in confirming that the fit has been maintained. The
strap and a pad 115 secured to side 103 of the corset may have a cooperating hook and
loop fabric attached to it to allow easy readjustment of the fit.
shows a variation of the adjusting straps in which the co-operating fastening
parts consist of a strap 113 which is overlaid by a known cooperating cam device 115
secured to side 103 of the corset and which can be irreversibly tightened onto strap,
preventing any further adjustment. Other securing devices may be substituted to
prevent adjustment once the correct setting is arrived at. Again the strap may have
indicia or other markings to allow visible determination of the strap adjustment.
shows the wearer side of a monitoring device in the form of a commercially
available data logger 117 secured to a patch 119 in turn secured to side 104 of the
corset in the region of the heart. No material underlies the device which is maintained
in contact with the chest wall by the tension of the medical corset. The data logger
116 is an integral chip device with an inductively rechargeable battery and has
electrodes 117, 118 which allow monitoring of surface currents in the chest wall. It
may also have an accelerometer. This is sufficient to monitor at least the wearers
heart rate, but may also include the wearers respiratory rate, relative lung inflation,
whether the initial tension in the corset is correct (in other words have the straps been
altered), and or whether the corset is in fact being worn. Such a monitoring device is
typically downloaded by Bluetooth to another device (phone, laptop) for monitoring
purposes and the corset may be draped over an inductive charger when not being
worn, for instance at night. The logger may be removed from the corset if necessary
for downloading or replacement.
In operation the medical corset is fitted to a wearer whose maximum lung capacity is
known and the straps of the corset are adjusted to limit the wearers available lung
capacity to a percentage of the forced vital capacity as measured. The length of the
206648NZ_CompSpec_V2_20200804.docx
straps may then be recorded, and if desired locks may be fitted to the straps to prevent
the adjustment being altered. The corset can readily be removed by sliding the front
fastening open and detaching the parts of the slide fastening from each other. It can as
easily be refitted without disturbing the length setting of the straps.
Preferably in the prevention of mesothelioma the available lung capacity is limited to
at or below 70% of the individuals predicted FVC.
It is to be understood that even though numerous characteristics and advantages of the
various embodiments of the present invention have been set forth in the foregoing
description, together with details of the structure and functioning of various
embodiments of the invention, this disclosure is illustrative only, and changes may be
made in detail so long as the functioning of the invention is not adversely affected.
For example the particular elements of the medical corset may vary dependent on the
particular application for which it is used without variation in the spirit and scope of
the present invention. This may include, for example, sculpturing the corset to
provide adequate breast support for female wearers including providing more rigid
shaped portions of the corset in the breast area,
In addition, although the preferred embodiments described herein are directed to
medical corsets for use in a lung function control system, it will be appreciated by
those skilled in the art that variations and modifications are possible within the scope
of the appended claims. For instance the corset could be used to limit stress on the
sternum after heart surgery.
Industrial Applicability
The medical corset of the invention is used in the prevention of injury to a person due
to excessive thoracic inflation. The present invention is therefore industrially
applicable.
