This invention relates to a device of the nature
of an instrument for inserting readily within a
cavity of the human body an article, such as a
pessary; especially for so applying such an
invention is to provide an applicator device in
the fabrication of which each of the foregoing
desirable requirements will be satis?ed, and
which will avoid certain departures from satis

rim and a body of elastic sheet material, (for
example sheet rubber) ; and more particularly an
applicator or inserter of the type having'a shank
provided near one of its ends with an abutment
to be engaged with the inner circumference of
factory performance which have characterized M
conventional devices of the same general type, '
these inconveniences including, among others:
(a) the need for exertion of an inordinate
amount of strength by the user in holding the
said annular rim of the article at a suitable
pessary stretched properly for accurate emplace- , 10

then be inserted within a body cavity, such as
(b) the existence of undesirable projections
upon the shank of the applicator, intended to aid
in holding the pessary in its stretched position,

In order to be satisfactorily serviceable for

application of ‘Rene M. Hay, Serial No. 679,221

shank of which terminates in a grooved head or
abutment adapted to be engaged with the inner

means whereby the ?exible member may be
connected selectively at various points along
its length with a region of the inserter shank
intermediate its ends, so that the ?exible mem

part of the user, whose attention can be devoted
10 exclusively to the operation of emplacement.
In the accompanying drawing, like characters
of reference have been applied to corresponding
parts throughout the several views which make
up the drawing, in which

By having a su?icient number of beads l8 on
the chain, and by providing in the shank of the 1O
inserter, a hole as M of suitable size and cross
section, it is possible to use one inserter for any
of the usual sizes of diaphragms that are now
available. This constitutes a notable advantage
of the novel inserter herein disclosed.

I have described what I believe to be the best
embodiments of my invention. I do not wish,
however, to be con?ned to the embodiments
shown, but what I desire to cover by Letters Pat
ent is set forth in the appended claims.

I claim:
1. An applicator or inserter device for install
ing in a cavity of the human body a distensible
article, such as a pessary of the type having a
resilient annular rim and a body of elastic sheet

nates generally an inserter device which is formed
at one end with a hook-member l0 and at its
other end with a head or abutment II, grooved
preferably, as at l2, to be engaged with the inner
circumferential region, as at l3, of the annular,
somewhat sti?‘ly resilient rim l4 of a pessary of
the diaphragm type, in the rim of which is en
rolled a coiled wire spring, indicated by the dotted
circle at IS. The hook member ID is used for
withdrawal of the pessary.
A pessary of this general type is disclosed in
co-pending application of Rene M. Hay Serial
No. 432,306, ?led March 1, 1930, for Pessaries and
method of making the same, now Patent No.
2,101,255.
The reference character I‘! designates general
ly a chain of known type, including metal beads
l8 and having at one terminal a hook l9 and at
its other terminal a ball 20, these terminals lim
iting the range of the chain’s adjustive and ac
tuating movements through the ori?ce 2|, which
is of keyhole shape and of suitable size at its
larger end to permit free movement of the ball
chain lengthwise.
In use, the pessary 22 is assembled with the
inserter device by so placing the portion 23 of the
rim M of the diaphragm in the groove l2 on the
inserter head or abutment, and the hook IQ of the
chain is attached to the other end of the dia
to phragm, the hook being so designed as to engage
the rim properly and not to injure the rubber of
member having near one end a hook device for 30
engagement removably with a region of said rim
remote from said abutment; and means whereby
said ?exible member may be connected at various
selected points along its length with an interme
diate region of said applicator shank, and serving 35
when placed under tension and so connected to
distend said article to any desired and suitable
extent for application.
2. An applicator or inserter device for install
ing in a cavity of the human body a distensible 40
article, such as a pessary of the type having a
resilient annular rim and a body of elastic sheet
material; said device comprising an elongated
metal shank having at one end a grooved abut
ment adapted to be engaged removably with the 45
inner circumference of said annular rim; a ?ex
ible metal tension member having near one end a
hook device for engagement removably with a
region of said rim remote from said abutment;
and means whereby said ?exible member may be 50
connected at various selected points along its
length with an intermediate region of said appli
cator shank, and serving when placed under ten—
sion and so connected to distend said article to
any desired and suitable extent for application.
3. An applicator or inserter device for install
ing in a cavity of the human body a distensible
article, such as a pessary, of the type having a
resilient annular rim and a body of elastic sheet
material; said device comprising an elongated 60
shank having at one end a grooved abutment

until one of the beads 18 catches in the slot por

a region of said rim remote from said abutment;
and means whereby a selected link of said chain
may be secured removably to said applicator
shank under tension, and serving when so se~

suitable extent for application.
4. An applicator or inserter device for install
ing in a cavity of the human body a distensible
article, such as a pessary of the type having a
resilient annular rim and a body of elastic sheet 75

material; said device comprising an elongated
metal shank having at one end a grooved abut
ment adapted to be engaged movably with the
inner circumference of said annular rim; a ?ex
ible tension member comprising a metal chain
having near one end a metal hook device for en
gagement removably with a region of said rim
remote from said abutment; and means whereby
any selected link of said chain may be secured
10 removably to said applicator shank under ten
sion, and serving when so secured to distend said
article to any desired and suitable extent for ap
plication, and to hold it upon said applicator
shank; said securing means being releasable by a
simple pulling movement upon the chain to per
mit the tension to be then relaxed, and to permit
disengagement of the abutment and of the hook
respectively from said rim, thus permitting said
20 article to assume the desired self-retaining posi
' 3
tion upon the part of the body upon which it is
thus installed.
5. An applicator or inserter device having the
features claimed in claim 1, in which a bead chain
constitutes said tension member, the chain-hook 5
being attached near one end of the chain and said
chain having constricted portions between the
bead components, and having an enlargement at
its free end; said inserter having in its shank a
keyhole aperture through which to thread said
chain, the aperture being of suitable dimensions
to permit lengthwise adjustive movements of said
chain, limited at one end of its range of adjust
ment by said chain-hook, and at the other end of
said enlargement, said keyhole aperture having its 15
walls disposed for engagement with said chain be
tween any selected beads, and adapted to nip the
chain when so engaged, holding it and the pessary
under tension.
