DRAINAE' TUBE Z'SheetS-Sheet 1 INVENTOR- 1.5100125 -H. GaLDMAN Jan. 14, 1958 l. H. GOLDMAN DRAINAGE TUBE 2 Shegts-Sheet 2 Filed July 16, 1953 INVENTOR. (8/0025 H. GOLD/YUM 9 Q v i X United States Patent DRAINAGETUBE Isidore H. Goldman, New York; N. Y.. Application July 16, 1953, Serial No. 368,375 a Claims. (Cl.128-'-350)f This invention relates to catheters; This invention has as its mainobject the'alleviation of pain and discomfort caused by' the conventional-type of catheter wherein the retention means wheninflated causes' a compression of the tube thereatresulting in painand discomfort by inability to void at a rate sufficient to relieve the pressure of the waste products.
Catheters currently in use-consistessentially of a flexible elongated tube terminating in a closed poi'nted end adapted'to be inserted into the urinaryorotherbladderor opening of the body and are'provided" nearsaid pointed end' with openings for drainage. Thesecatheters are-further provided with inflatable members adjacent said drainage openings whereby to retain the closedendof the catheter within the bladder and also with independent drainage and inflation ducts'extending to the outer open endofthe device. However, sincethe walls'ofl'the drainage duct also form the inner walls for the inflatableportion, the air or other compressedfluid within theinilatabIe portion tends to collapse the walls of the drainage'du'ct inwardly, seriously impairing the effectiveness of the device.
It is accordingly a principal-object of the present invention to provide an improved catheter of'the type having inflatable retention means wherein collapse of the walls of the drainage-duct is prevented when the retention means are inflated.
It is another object of present invention to provide an drawing. It is to be noted that the drawing is intended to serve the purpose of illustration only, and that it is neither desired nor intended to limit the invention necessary to any or all of the exact details of construction shown except insofar as they may be deemed essential to the invention.
Referring briefly to the drawing,
Figure l is a perspective view of a catheter embodying the features of the present invention and with the retention means shown deflated;
Fig. 2 is a longitudinal sectional view taken along the line 2-2 of Fig. 1;
Fig. 3 is a transverse sectional view taken along the line 3-3 of Fig. 2;
Fig. 4 is a perspective view showing the retention means inflated and the device operative for use;
Fig. 5 is a view similar to Fig. 2 but showing the retention means inflated Within the bladder walls;
"ice
Fig. 6 is aperspective-view ofthe-insert preventing eollapse of the drainage duct, shown alone;
Fig. 7 isaview similar to Fig. 5 of a conventional catheter showing the collapse of thedrainage duct'walls upon inflation of the retention means; and
Fig. 8 is a fragmentary view similar to Fig. 2' but showing' a modified form of-the'invention.
Referring now in detail to the drawing, ltl-represents an elongated flexible tubeof rubber or other suitable material having a closed; pointed end 11 to facilitate insertion intothe urethra or other bodyopening, the outer open end of the tube: ltl being flared'outwardly...as at 12- and terminating in a relatively large cylindrical portion13.
The outer open end of the cylindrical vportion vided with a suitablestopper.14 (Eig.44.).
The tube 10* adjacent the-pointed end11 is provi ed withsuitable drainage openings 15..
The interior of'the tube 101at=one side is reinforced-1a at 16, this reinforced portion extending from near the openings 15 to near theflared portioni1-2 andi being provided with an inflationductli" over substantially: the length thereof.
The tube 10 adjacent the outwardly flaredportion'. 12 is integrally formed with a substantially L-shaped tube 18having an outwardly flared outer open end 19 andcomrnunicating with the inflation duct-17;
The tube 10 near the drainageopenings 15 is providd with anannular slit 20p1'ovidin g an annular outer membrane 21 (Fig. 2). The upper end-ofthe drainage duct 17 communicates with the annular slit 2tlby. meanszofca cut out or opening 22 (Figs. 2 and 3).
A hollow insert 23 of substantially crescent-shaped cross section to facilitate fluid'flowf in the inflationmeans is positioned within the tube lowithin the portion thereof having the annular slit 20, the concave-portion 24iofsthe insert snugly receiving therewithin the correspondingly shaped reinforced portion 16 having the inflation duct-'17 It will be noted that the construction permitsthe membrane 21, when collapsed, to present a smooth exterior to the tube 10' and to thereby facilitate the insertionand removal of the same between the walls 25-- of the bladder.
Reinforcing tubes, I10USh0Wl1; may beprovidedwithin the inflation duct 17 during use.
To inflate the membrane 21 to the positions of Figs. 4 and 5, a hand pump, not shown, or other suitable inflating means may be connected to the flared portion 19 of the tube 18. After inflation of the membrane 21, the tube 18 is doubled up, as shown in Fig. 4, and closed off with a rubber band 26, or other suitable means.
Thus, the catheter will be retained in the proper position within the bladder walls 25 by means of the inflated membrane 21 after the catheter has been inserted to the proper position.
The insert 23 prevents the inward movement of the walls surrounding the drainage duct 27 when the membrane 21 is inflated. Were it not for the insert 23, the walls of the drainage duct 27 would be forced inwardly, as shown in Fig. 7, and preventing the proper drainage of the body liquid passing into the tube through the drainage openings 15.
The insert 23 may be fabricated of any suitable material which will not be affected by the drainage liquid, its only requirement being that it have sutficient rigidity to prevent the collapsing of the drainage duct 27 within the membrane portion 21. This member 23 may be molded or aflixed integrally with the catheter during production or this portion of the catheter may be treated for greater hardness and rigidityduring vulcanization.
By providing the insert 23, it will be apparent that greater pressure may be exerted within the membrane 21, without closing the drainage duct 27, permitting a 13 isprogreater expansion of the membrane and greater control of the internal pressure upon the walls 25. This is particularly important when it is desired to control bleeding from blood vessels Within the walls 25 in post-operative cases.
Also, while in the drawing the invention has been shown in connection with a catheter having one inflation duct 17, it will be readily apparent that several inflation ducts may be provided on opposite sides of the tube, and that the present invention is equally applicable in such cases. Also, while there has been shown an annular membrane 21, it will be apparent that the invention is equally applicable to cases where a plurality of independent membranes 21 are provided for retaining the catheter within the bladder or wound.
Referring now particularly to Fig. 8, there is shown a modified form of the invention wherein the insert 23a of substantially crescent-shaped cross section is now formed from a continuous strip of spring wire.
In other respects the form of the invention shown in Fig. 8 is the same as that shown in Figs. 1 through 7, and like reference numerals identify like parts throughout the several views.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
