This invention is a prostate gland massage

The outer end of the shank 4 is provided with
a distinctly elongated, cylindrical head 5. This
head is made of rubber as, also, is the shank and.
is today a considerable demand in the medical
its associated guard and handle. It is a feature
It is well known that material bene?t is ob
tained in numerous gland cases by the gentle
profession and among prostate gland sufferers for
of the invention that the head 5 is materially
an effective, non-irritating and painless means
for the facile treatment of these internal glands.
Prior to my development in this art' there was
not available on the market any simple, practical
device which could be safely and practically em
ployed for prostate gland treatment or massage.
softer than the shank so as to painlessly adapt
Because of peculiar anatomical disposition of
15 these glands and the danger of in?ammation a
device for effective and unharmful treatment
must have incorporated in it certain properties,
capacities and safety features. It must have suf
?cient ?exibility to quite easily bend in conform
20 ance with the body channel leading to the gland
to be treated and yet it must have enough stiff
ness not to fold back and to be pressible onward
until its tip is juxtaposed at the gland. It must
have su?icient ?rmness to afford the desired re
25 sistance pressure at the tip to produce the requi
site massage pressure. And, importantly, it must
be possessed of a high degree of safety against
mechanical break-down.
It is, therefore, an object of the present inven
30 tion to provide a device, for the treatment of the
speci?ed gland, which embodies factors of con
struction for the satisfactory accomplishment
of the treatment with the stated desired mechan
ical safety.
The invention consists in certain advancements
in this art as set forth in the ensuing disclosure
and having, with the above, additional objects
and advantages as hereinafter developed, and
whose construction, combination and details of
40 means, and the manner of operation will be made
manifest in the description of the herewith illus
trative embodiment; it being understood that
modi?cations, variations and adaptations may be
resorted to within the scope, principle and spirit
45 of the invention as it is more directly claimed
Figure 1 illustrates the invention in sectional,
side elevation, and
Figure 2 is a cross-section on line 2—2, Fig. 1.
This embodiment incorporates a handle 2 of
suitable length and of a diameter providing for
its substantial or ?rm grip in the closed adult
hand. At its inner end the handle joins integral
55 ly with a discal guard 3 beyond which extends
its shape to the gland body being treated, the
elongation of the head 5 providing for a length of 10
area for massage stroke without such irritation
as the ridge irritation which would be due to a
change of size from shank to head incidental to
movement of the head at the locale of the gland.
The shank 4 must be of rubber of such quality
and stability that it can be entered into the chan
nel and press the head toward the gland and then
to be stiff enough to apply a desired degree of
pressure of the head on the gland, but at the same
time it must be sufficiently bendable as to pain
lessly adapt itself to the curvature of the channel.
Further, attention must be had for the possibility
of break-down of the rubber shank with the con
sequence that the head of the instrument might
be left in the canal. Therefore, in producing a
device with these requisites the purer the quality
of rubber used the greater will be the ?exibility
and less the danger of break-down, either in the
development of small cracks or entire separation
of broken parts. It is therefore necessary to- re
enforce the shank 4 of such soft rubber so as to
secure the necessary bending reaction to apply
the head to the contiguous gland, after the device
is inserted, with a massaging pressure.
This reenforcement is here acquired by means
of a helical metal spring 6 whose several coils are
spaced apart enough to permit the rubber mass
of the shank to solidly ?ll within and between
the coils as the rubber is cast thereabout. Thus
the spring builds up the shank to the desired 40
stiffness and yet provides plenty of ?exibility, and
provides for a high degree of safety of retraction
in the event that the shank should break into
sections. And still no metal parts or other hard
portions are presented to cause undesired irrita 45
tion of the tender membranes encountered.
For economy the guard 3 and the handle 2 are
made of the same rubber stock as the shank, but
the increased diameter of the handle over the
shank gives to it the needful stiffness to effectu
ally operate the instrument.
Suitable ?uid ducts are shown cored in the
handle and the shank to provide for circulation
of ?uid to the head 5 as may be desired, these 55
ducts being encircled by and isolated from the
spring 6.
The greater diameter of the handle gives to it
a greater, desired degree of ?rmness than the ?ex
ible shank, though of the same stock of rubber,
for economy of manufacture, and, as above stated,
the coiled spring device embedded in the shank
and anchoring in the handle provides a safety
factor for the Withdrawal of parts of the shank
10 in eventv of its segmentation axially.
Attention is directed to U. S. application for
patent, Ser. No. 20,958, filed May 11, 1935, over
which the device of the instant invention is an
coaxial, embedded, helical spring whose coils are
spaced in the embedding rubber mass, whereby
to stiffen the shank and provide a safe retractive'
connection of parts of the shank in event of its
breaking into separable axial sections the shank
having ?uid ducts encircled by and isolated from
the spring.
