INVENTORS ATTORNEY United States Patent 3,161,197 CATHETER Wayne W. Glas, Wayne Eounty General Hospital, Eloise, Mich, and Charles 3. Trick, 31811 W. Chicago Blvd, Livonia, Mich.

Filed July 2, 1962,- Ser. No. 2%,879 4 (Iiaiins. (Cl. 128-295} The present invention relates to an improved catheter of a type described in copending application S.N. 65,840, now abandoned, filed in the name of one of the coinventors of this invention.

The catheter as described in copending application SN. 65,840, now abandoned, is adapted to be secured to a human penis of a male patient. This catheter comprises a pliable, foldable bag portion with an inlet opening or open end at one side. A tube is attached to the other side of the bag portion for conducting urine from the bag portion to a receptacle. An adhesive wrapping means, which is attached to the open end, is adapted to be wrapped around the human penis to substantially seal a portion of the penis in the bag portion of the catheter.

Although this catheter is a considerable improvement over other catheters found in the art, it has been found that the foldable bag portion may collapse upon being secured to the male patient when the patient moves his legs. The collapse of the pliable bag portion may interfere with the flow of urine being discharged by the patient through the catheter to the receptacle. Further, the opening of the drainage tube within the bag portion may be partially blocked by the sides of the bag portion when they are accidentally folded by the patient or the bed covers.

The obstruction to the flow of urine may result in the bursting of the bag portion or loosening of the adhesive wrapping means to cause the spilling of the urine over the patient and the bedding. Also extreme discomfort may be felt by the patient if the bag portion is filled with urine and is not readily and speedily drained therefrom.

To overcome these disadvantages, the improved catheter embodying this invention comprises a pliable, foldable bag portion having an inlet opening at one end and means for connecting a tube at the other end. The bag portion is larger in cross-section than the human penis to which it is to be attached. A substantially fiat member is placed within the bag portion. This member has one end secured to the connecting means and another end projecting along a portion of the periphery of the bag portion to maintain the bag portion in an unfolded condition when the catheter is secured to the penis by an adhesive wrapping means.

It is, therefore, an object of this invention to provide an improved catheter which is comfortable to the male patient and prevents the leakage of urine from the catheter.

It is a further object of this invention to provide a simple, low cost catheter which can be readily folded for shipping or storage purposes when not in use but will not fold or collapse when in use.

A still further object of this invention is to provide an improved catheter that will prevent any interferences with the draining of urine from the bag portion into a tube which is connected to a disposable receptacle.

Other objects and advantages of this invention will become more apparent from the following description, particularly when considered in connection with the accompanying drawing in which:

FIGURE 1 is a plan view, partially in section, of an improved catheter embodying this invention and shown when in a flattened condition;

FIGURE 2 is a perspective view of a member that it is a component part of the catheter of this invention and which is shown detached from the catheter for greater clarity;

FIGURE 3 is a cross-sectional view taken along line 3-3 of FIGURE 1; and

FIGURE 4 is a plan view of the catheter embodying this invention and shown when in use.

Referring now to the drawings and especially to FIG- URE 1, there is seen a catheter, generally designated as 11, which comprises a bag portion 12. The bag portion 12 is manufactured from a pliable, foldable, impervious material such as polyethylene although rubber or any other impervious, flexible material will be satisfactory.

The bag portion 12, which is supplied in a flattened con dition, is in the shape of a truncated rectangle, having two right angles 13 and 14 at one end of the bag portion 12 and an obtuse angle 15 and an acute angle 16 along the truncated other end. The bag portion 12 has an intake opening at the edge between the right angles 13 and 14 while the remaining edges are sealed except for a substantially smaller outlet opening 17 provided at the acute angle 16. Y

A member 18, which is positioned within the bag portion 12, comprises an apertured portion 19 that is integrally formed with a flat wing shaped segment 21. The apertured portion 19 has a first part 22 provided with a funnel shaped opening 23 which is in communication with its aperture as best seen in FIGURE 2. The periphery of the first part 22 is received within the outlet opening 17 while a second part 24 of the apertured portion 19 extends through the opening 17 to the outside of the bag portion 12.

The bag portion 12 at the acute angle 16 is sealingly attached to the periphery of the first part 22 of the apertured portion 19. A tube 25, which may also be fabricated from polyethylene if desired, has one end sealingly connected to the periphery of the second part 24 of the apertured portion 19. The tube 25 may also partially encompass the part of the bag portion 12 which extends over the first part 22. The other end of the tube'25 (not shown) may be placed in a disposable receptacle to accumulate the urine drained from the bag portion 12 through the apertured portion 19 and its associated tube 25.

In FIGURE 3 is seen an adhesive wrapping means'26 which is utilized to attach the catheter 11 to a human penis. The adhesive wrapping means 26, in this instance, consists of a flexible band 27 having an adhesive coating 28 on one surface. A protective sheet 29, such as paper, covers the adhesive coating 28. A portion of the protective sheet 29 is cut away where the band 27 attaches to the bag portion 12 as best seen in FIGURE 3. This portion of the band 27 extends beyond the bag portion 12 in both a longitudinal and a lateral direction with respect .to the axis of the truncated rectangle.

When the catheter 11 is to be applied to a male patient, the protective sheet 29 is stripped away from the adhesive coating 28. Then, as seen in FIGURE 4, a portion of the human penis, designated as 31 and shown by phantom lines, is inserted through the open end into the bag portion 12. The band 27 is wrapped around the human penis 31 to seal a portion of the penis 31 in the bag portion 12, thereby securing the catheter 11 to the male patient. .The outlet opening 17 is pointed downwardly to provide for effective drainage of the urine.

The flat wing shaped segment 21 of the member 13 projects in an upward and inward direction within the .bag portion 12 while the apertured portion 19 of the member 18 is securely held at the acute angle 16. This prevents the pliable bag portion 12 from collapsing or folding to interfere with the flow of urine. Also the fun- 3 nel shaped opening 23.of -the member 18 facilitates'th draining of the urine from the bag portion 12 to the tube 25 Without resulting in the backing up of the urine to cause discomfort to the male patient.

It can be readily understood that the low cost, flat.

member 18 greatly improves the functioning of the catheter 11. v I

It Will be understood that the invention is not to be limited to theexact construction shown and described, that various modifications and changes may be made without departing from the spirit and scope of this invention as defined in the appended claims.
