Application October 21, 1939, Serial No. 300,564
4 Claims.
My invention relates to improvements in catheters.
The primary purpose and object of my invention is for the drainage and the treatment of the bladder and of the urethra tube leading from the bladder to the exterior.
My invention is primarily intended for use in the treatment of males wherein the catheter is inserted longitudinally through the duct of the penis into the bladder cavity.
The invention is comprised primarily of an inner drainage tube and an outer sheath which encompasses the drainage tube and which permits of the draining of the bladder both of its normal secretion and of the treating solution. Heretofore in the treatment of the duct of the penis it has been difficult in the presence of a catheter to insure the treating solutionsencountering the exposed surfaces of the duct of the penis without first removing the bladder catheter.
Through the use of my new and improved device, the bladder cavity may be directly drained or emptied without the contents being permitted to engage the walls of the duct leading from the bladder cavity through the penis to the exterior.
Also through the use of my new and improved device it is possible to separately irrigate the bladder and the urethra with treating solutions both in the forms of liquids, fluids and semifluids through the one device while in place.
My invention is comprised of an inner perforated tube that is. admitted into the bladder cavity through the bladder-urethral orifice and in which the enlarged portion of the catheter is not permitted to enter through the bladderurethral orifice to thereby confine the irrigating solutions to the duct of the penis.
The primary object of the invention is to provide in the single instrument a device that may be used for the draining of the bladder cavity, and for medicating the same, and for draining and medicating the duct of the penis leading from the bladder cavity to the exterior through the penis.
A further object of my invention is to provide a catheter which may be so constructed that it will drain the bladder and treat or medicate the urethra cavity without the necessity of removing the catheter from the urethral orifice, thus preventing any further irritation that may be caused by the same being removed and replaced.
A still further object of my invention consists in providing a catheter that may be used for draining and irrigation, and also for the treatment with medicated materials through the a catheter into the duct running longitudinally of the penis and into the bladder cavity.
And a still further object of my invention consists in so constructing the device that it may be made to aerate and otherwise treat the duct of the penis.
With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the es sential elements of which are set forth in the appended claims, and a preferred formof embodiment of which is hereinafter shown with reference to the drawing which accompanies and forms a part of this specification.
In the drawing:
Fig. I is a sectional side view of the structural detail surrounding the penis and the orifice duct connecting the penis with the bladder cavity In this view my device is shown in place for applying a medicament to the duct of the penis.
Fig. II is a side view partially in section oi the coiled catheter shown removed from use and in readiness for use. i
Fig. III is a sectional end view of the catheter. This view was taken on line 33 of Fig. II, looking in the direction indicated.
Fig. IV is a sectional end view of the catheter illustrated in Fig. II. This view was taken on line 4-4 of Fig. II, looking in the direction indicated.
Fig. V is a sectional end view of the catheter illustrated in Fig. II. This view was taken on line 5-5 of Fig. II, looking in the direction in.- dicated.
Like reference characters refer to like parts throughout the several views.
I have shown my device in Fig. I as being in position and in use for draining the bladder cavity l of the male human being. The outer tube 2 is entered longitudinally of the penis and extends longitudinally thereof through the duct of the penis that communicates the penis with the bladder cavity.
The tube running longitudinally of the penile urethra 3 through the walls in which the sphincter muscle 4 is located, through the prostate 1gi lan 5 and through the bladder urethral ori- The catheter is comprised of an outer tube 2, the outer tube 2 having a plurality of ports I disposed at spaced intervals in the outer wall and communicating the space 8 disposed between the outer tube 2 and the inner tube 9. The inorifice extending through the prostatic urethra to permit the inner end [3 of the inner tube 8 extending into the bladder cavity.
A port I4 is disposed upon the outer insertable end of the inner tube 8 to permit the draining of the bladder cavity and for the irrigating of the bladder cavity.
The discharge end l5 of the inner tube extends beyond the confines of the outer tube and extends through the Wall thereof to permit draining material flowing therefrom into any suitable receptacle, and I provide a head IS on the outer end of the outer tube 2 into which may be threaded any suitable receptacle as a collapsible tube I! which may contain any suitable medicament that is to be used in the treatment of the penile urethra, or an irrigating solution connected to a suitable supply of fluid under pressure as a water bag may be connected thereto.
When the catheter is being used for draining purposes only a threaded plug l8 may be used for closing the outer end l6 of the outer tube 2. While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to' be understood that it is not intended to confine the invention to the embodiment herein shown and described, as it is susceptible'of embodiment in various forms, all coming within the scope of the claims 7 which follow.
' What I claim is:
I. In a device of the class described, the combination of a pair of tubes with the respective tubes being coaxial for the major portion of their length and with the inner tube passing through the end of the outer tube at one of its ends and extending'beyond the outer tube on its outer end, and with the respective tubes being sealed together where the inner tube passes through the outer tube and the outer tube having a plurality of ports extending through the wall of the outer tube'and the inner wall of the outer tube and the outer wall of the inner tube being in spaced relationship with each other, and a groove disposed longitudinally and upon the outside surface of the outer tube, and a female threaded connection being disposed at one end of the outer tube.
2. In a device of the class described, the combination of a pair of tubes, with one of the tubes being an outer tube, and the other one of the tubes being an inner tube, with one end of the inner tube extending beyond the end of the outer tube, and with the outer tube being sealed to the inner tube where the same passes through the end of the outer tube, and the opposite end of the inner tube passing through the wall of the outer tube and being sealed thereto where the same passes through the outer tube, a plurality of ports communicating the inside of the outer tube with the outside of the outer tube, a groove disposed longitudinally of the outer surface of the outer tube and a threaded connection disposed at either or both of the ends of the tubes.
3. In a device of the class described, the combination of a pair of tubes with the said tubes being coaxial for the major portion of their length, with the inner tube extendingbeyond the length of the outer tube at one of its ends, a plurality of ports disposed upon the inner. end of the inner tube', and with the oppositely disposed end of the inner tube passing through'the wall of the outer tube, grooves disposed upon the outside of the outer tube and running longitudinally thereof, ports communicating the base of the groove with the inside of the outer tube and with the inner wall of the outside tube, and the outer wall of the inside tube being spaced apart where the twotubes are coaxial.
4. In a device of the class described, the combination of a pair of tubes, one being an outside tube andthe other being an inside tube, and with the two tubes being coaxial for the major portion of their length and with the walls of the respective tubes being spaced apart, and with the inside tube projecting beyond the confines of the outside tube on its respective ends, and with the projecting end of the inside tube being ported, a plurality of grooves disposed longitudinally of the outside tube and upon the outside of the outer tube, a plurality of spaced ports 'c'ommuni cating the groove with the interior of the outside tube, and means for forming a connection upon the ends of the tubes, and means for attaching a plug or pressure applicator thereto.
