The automated catheter assembly of the instant invention has been
designed to simplify the catherization of either the male urinary
bladder or the female urinary bladder. The automated catheter
assembly may utilize substantially any accepted rubber catheter or
its equivalent and includes structure whereby the associated
catheter may be lubricated in a sterile manner as it is placed in
use and inserted into the female urethra or male penis without
contamination of the rubber catheter during insertion. Also, the
automated catheter assembly is provided with a support body having
a bore formed therethrough and the associated rubber catheter is
advanced through the bore while one hand supports the body in
alignment with the female urethra or male penis. Also, the body
includes opposite side shield portions whereby the adjacent
portions of the patient's body are shielded against contact with
the distal end of the catheter and the body and shield may be
readily broken away from the proximal end of the catheter after the
latter has been inserted.
The main object of this invention is to provide a catheter assembly
designed to simplify the catheterization of male and female
patients.
Another object of this invention is to provide a catheter assembly
wherein the catheter may be readily lubricated in a sterile state
immediately prior to insertion of the distal end of the
catheter.
Still another object of this invention, in accordance with the
immediately preceding object, is to provide a catheter assembly
including shield structure for shielding the distal end of the
catheter from contact with parts of the body other than the urethra
of a female and the penis of a male.
Another important object of this invention is to provide an
automated catheter assembly in accordance with the preceding
objects and which may be used in conjunction with a conventional
catheter.
A final object of this invention to be specifically enumerated
herein is to provide a catheter assemblage in accordce with the
preceding objects and which will conform to conventional forms of

Referring now more specifically to the drawings, the numeral 10
generally designates a catheter assembly for utilization in
conjunction with male patients. The catheter assembly includes a
generally cylindrical body 12 having a longitudinal bore 14 formed
therethrough. The rear or proximal end of the body 12 is
diametrically reduced as at 16 and the intermediate portion of the
body includes an upwardly opening well 18 which opens downwardly
into a transversely enlarged intermediate portion 20 of the bore
14. Further, a disk-shaped shield 22 is carried by the forward
distal end of the body 12 and includes a central opening 24 therein
registered with the forward end of the bore 14. The well 18 is
defined by an upstanding cylindrical wall 26 including
circumferentially spaced bulbous portions 28. A cover 30 including
a downwardly opening cylindrical channel 29 is provided and the
channel includes axially spaced sets of circumferentially spaced
enlarged portions 29' into which the bulbous portions 28 are snap
receivable, the outer portions of the cover on opposite sides of
each of the enlarged portions 29' being slotted at 29" and the
cover being constructed of resilient material. A generally
spherical hollow lubricant bladder 32 is seatingly captive within a
downwardly opening partial spherical recess in the cover 30. The
lower end of the bladder 32 is rupturable by means of an upwardly
projecting spike 33 carried by a cross brace 34 below the cover 30
upon down displacement of the cover 30 from the ready position
thereof illustrated in FIGS. 3 and 4 of the drawings, the cover 30
being releasably frictionally retained in the upper ready position
by the bulbous portions 28 being seated in the lower set of
enlarged channel portions 29'.
The left hand side of the body 12 is provided with a longitudinally
extending radial slot 48 and the left side of the shield 22 is also
provided with a radial slot 50. In addition, the right hand side of
the body 12 is provided with similar longitudinally spaced and
extending slots 52 and 54 and the right side of the shield 22 is
provided with a radial slot 56 which opens into the opening 24 but
terminates radially outwardly a spaced distance from the outer
periphery of the disk 22. Further, the upper sections of the right
and left hand side portions of the shield 22 include depending
protective flanges 55 and 57 supported from the rear surfaces
thereof and which overlap the rear extremities of the slots 56 and
50.
The upper marginal edge portion of the disk 22 includes a forwardly
projecting partial cylindrical shield flange 58 and the front
surface of the shield 22 includes a pair of forwardly projecting
integral lugs 60 disposed above and below the outer end portion of
the slot 50. Finally, the lower marginal edge portion of the shield
22 includes a forwardly projecting handle 62 terminating at its
forward end in a downwardly and reversely curving fingergrip
64.
The distal end 66 of a catheter 68 is loosely telescoped into the
rear end of the bore 14 and positioned in the transversely enlarged
intermediate portion 20 of the bore 14 below the tearable membrane
36. The open end of a protective bag 70 in which all but the distal
end of the catheter is received is supported from the diametrically
reduced neck or end 16 of the body 12 by means of a clamp ring 72,
the latter being provided with a longitudinal slot 74 aligned with
the slot 50 and a pair of axially spaced longitudinal radial slots
76 registered with the slot 54.
In operation, the entire catheter assembly 10 is packaged within a
sealed protective envelope (not shown). When it is desired to use
the catheter assembly, the latter is removed from its protective
envelope and the cover 30 is downwardly displaced to rupture the
bladder 32 whereby the lubricant within the bladder will flow down
into the transversely enlarged portion 20 of the bore 14 and
lubricate the distal end of the catheter 68. Then, the assembly 10
is held in one hand (with the associated male organ) by the
fingergrip 64 of the handle 62 the manner illustrated in phantom
lines in FIG. 1 of the drawings and the catheter 68 projecting out
of the rearward end of the body 12 is pushed forward with the other
hand through the envelope or bag 70 until the distal end 66 of the
catheter has been inserted in the bladder, the handle 64 serving as
a "docking" guide to facilitate alignment of the head of the male
organ with the distal end 66 of the catheter 68. Then, the lugs 60
are engaged in both hands and pulled apart in order to split the
shield 22 along the slots 50 and 56 and to also split the body 12
along the slots 48, 52 and 54 as well as the clamp ring 72 along
the slots 74 and 76, see FIG. 10. Thereafter, the two halves of the
assembly 10 are removed from about the catheter 68 and the envelope
70 may be slid from the proximal end of the catheter 68.
In FIGS. 11 through 16 of the drawings there may be seen a modified
form of catheter assembly 10' constructed in accordance with the
present invention, but which is adapted to be used in catheterizing
female patients. Various of the components of the female catheter
assembly 10' are identical, or at least substantially identical, to
corresponding components of the male catheter assembly 10.
Accordingly, the various identical or nearly identical components
of the female catheter 10' are designated by prime reference
numerals corresponding to the numerals applied to the corresponding
components of the male catheter illustrated in FIGS. 1 through
10.
The female catheter assembly 10' differs from the male catheter
assembly 10 in that the female catheter 10' does not include a
shield corresponding to the shield 22 or the equivalent of the
handle 62 supported from the shield 22. Rather, the lower portion
of the body 12' of the female catheter assembly 10' is provided
with a depending support rib 13 from whose lower marginal portion a
horizontal transverse flange 15 is supported. The opposite side
marginal portions of the flange 15 converge forwardly and have
upstanding opposite side shield flanges 17 and 19 supported
therefrom notched at their forward ends as at 21 and 23,
respectively. Also, the flange 19 includes an upwardly projecting
handle 25 intermediate its front and rear ends.
In operation, the female catheter assembly 10' is moved into
position by one hand grasping the handle 25 and thereafter used in
substantially the same manner as the assembly 10, except that the
entire shield comprising the rib 13, flange 15 and the flanges 17
and 19 are broken away from the upper half of the body 12' when the
lower half of the body 12' is separated from the upper half. Also,
the body 12' includes an upstanding transverse flange 27, see FIG.
13, which serves to interconnect the forward ends of the wall
portions 26' corresponding to the wall portions 26.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
shown and described, and accordingly all suitable modifications and
equivalents may be restored to, falling within the scope of the
invention.
