CATHETER.

once being bad therein to the aeeompanying drawings. I r
My invention rolatesr to an ijliliJi'OVt-Hl construction of catheter for use in diseases of the bladder.
to use a catheter there are conditions of the bladder under which. the catheter of usual construction-that is, with the ordinary fine perforations as an inlet therciniodoes. not work readily or satisfactorily, or su bserve fully the results expected from it. Examples of such unsatisfactory operation are seen where there is a good deal of mucus present in the bladder, such mucus being apt to surrouml. or lie upon the end of the catheter, clogging or stopping the fine apertures thereof 5 and preventing the ingress of fluids to be drawn off, and again where the bladder is in a flabby condition the walls are apt in close around the eatheier and similar-Ly prevent the ready ingress and (low of liquids, while if much sediment be present it clogs, even sometimes filling in part or completely, the apertures, with again eonseiiuient failure of the catheter to fully pertkn'nr its functions. Such failure is especially apt to happen in nearly if not quite all forms of chronic discases of the bladder, and notably so in cys titis.
The object therefore of I my invention is to furnish a catheter reliable and efficient in operation when the use of a catheter is indicated and that in all conditions and diseases of the bladder, in which danger of clogging or of failure to perform its functions is obviated, whose interior maybe readily cleansed, by which bits of mucus, usually clogging an ordinary catlu'eter, may be readily drawn oft, one that may be used on occasions as alithontriptor to a certain extent and with small obstructions, otf comparatively simple eonstruct-ion, readily used and operated, and durable; to which ends it consists in the teatures more particularly horeimilter described and claimed.
In the drawings is illustrated a catheter embodying my invention, in which drawings Figure 1 is an outer plan View thereof; Fig. 2, a longitudinal section; Fig. 3, an enlarged view of the bulbous headand cleaningloop.
In these figures the reference-nmneral 1 indicates the body of the catheter, the tube through which after insertion fluids are cen- 'eyedl It is of the ordinary plain tubular construction, curved at the entrance end in the It is well known that when it is necessary usual way, said end preferably being unperforated. Instead, however, of being rounded or ovaled at the end, as is usual, it is cut off square at the end, leaving an inlet thereat of the same or about the same size as the body of the tube at such end, as seen at 9 in the figures. For the closure ofthis open on d and the easy insertion of the catheter, as well as for other purposes, some of which are hereinafter referred to, a bulbous or rounded head, 3, is used, preferably solid, and attached to one end of a wire, 5, passing through the body or tube 1 and projecting at its rear or outlet end. For convenience of manipulation, such end is provided with a handle, (3, though the .objeet of such handle, attachable or detaclr able from the wire 5, may be accomplished by forming a simple loop at the end from. the wire itself. If the wire 5 and the wire 10, hereinafter noted, he of ductile metal, they or either of them may be bent, as at 7, the step orledge serving as a stop to limit the amount of in ward movement of the wire and consequent lifting of the head 3 from its seat at the end 2.
This construction, as thus described, forms, it is seen, a very efficient catheter, having an area of opening so large as to greatly obviate danger of clogging, for if mucus should lodge against'the end 2 the working of the head 3 back and forth upon its seat would cut away the obstructing bits of mucus and permit them to pass out through the tube 1, while by the use of the head projected from its seat the wall of the bladder, when the latter is in a flabby condition, may be so kept away from the inlet at end 2 that. the How thereinto is not impeded.
ciency, the bulbous head 3 should be formed with a rim, at, by cutting away part of the To add however to its effibase, and so that the rim 4 sits snugly upon the end 2, as a valve upon its seat, the lower part of the head passing; within the tube 1. Such construction aidsin the erushingot' any small obstructions which may lodge at the top of the end 2, and in the cuttingaway of mucus, &'e., which tend to clog the flow.
To provide tor the ready and thorough cleansing of the interior, a seeond wire, 10, is passed up through the tube 1, its outer end being furnished with a loop or handle, l2.
At its inner or upper end it is formed intoor open end 3, the wire 5, ,mssing therethrongh,
has set-urml to it a eireularloop, l 'l,surronndingthe wire 5, and ot a size to sol-ape the interior wall of the eatlieter-body and to tit around the port on of, the head below the rim t, where it would ordinarily rest when not in use. The reeiproeation of this loop within the tuhe would readily remove, it is easily seen, an 3' adherent matters therefrom. At the rear end ot. the tuhe or body 2 there v should be one or more ledges or threads, 9, for the seeurement of a flexible pipe slipped thertmver, so that the eat'het'er may be transformed into a syringe tor the intn'oduetion instead of the removal of fluids.
Hming thus described my inventiomwhat I claim. is-
.1. A catheter having a Full open inlet end, 5 a head adapted to be seated thereon, and act as a valve, and a wire attached to such head and passing through the hodyot' the (wttheter, substantially as set forth.
2. A eat-heter composed of tube 1 with full inlet end 2, a head, 3. with rim orledge 4, and wire 5, a "acted 1 tie head and passing through the tube 1, substantially as set forth. 3. The ('(nnbinatiou of tube 1 with full the head 23, attached to such wire and seating upon the end 2, the wire 10, and the loop 11,
' si'lrroumling' the wire 5 and partot the head 23, substantially as set forth.
In testimony whereof I at'fix my signature in presenee of two witnesses.
