Definitions

  • a suprapubic catheterization system features a suprapubic catheter having an advantageously large drainage lumen that consists of a stylet with a thin wall catheter external to it.
  • the stylet is a combination of a trocar or puncturing device that prevents tissue coring and a hollow cannula having side openings thereon that coincide with openings on the external catheter.
  • the openings on the cannula and catheter permit urine to flow through the proximal end thereof, thereby indicating that both trocar and catheter are positioned correctly well inside the bladder.
  • the inner stylet can then be removed and a routine hook-up to the catheter can be accomplished.
  • the catheter tip may be coiled so as to assist in the retention of the catheter intracystically.
  • Irrigation of the bladder can be simply accomplished by inserting a luer fitting syringe into the system for irrigating a blocked catheter or the like.
  • the catheter may also be provided with a slidable locking mechanism for stabilizing the longer internal stylet type of catheter.
  • a preferred collet type device can be slid down the external catheter to a desired and convenient length prior to insertion and is locked in place, and can be made to have an adhesive coating on a side thereof so that the catheter may be affixed on the skin of the abdomen to prevent pull-out after its installation and during drainage.
  • the entire catheterization system can be pre-connected for ease of use and storage, and yet the individual portions thereof can be easily disconnected and separated from each other when used on a patient, for application of irrigation, sampling and medicine installation.
  • Suprapubic catheterization a relatively new and as yet not routinely used technique for draining the bladder, is the insertion into the urinary bladder of a drainage tube by a route through the skin in the lower abdomen above the pubic bone. The procedure is normally carried out by placing a regular transurethral catheter into the bladder and instilling liquid therein until the bladder is sufficiently full that it can be palpated through the skin. This catheter is then removed and the suprapubic catheter is placed into the bladder by one of two means the trocar method or the needle method.
  • a suprapubic catheter avoids further or continued irritation of the urethra following surgery in that area.
  • a transurethral catheter might be used as a splint to keep the urethra from healing shut.
  • the urethra is not operated upon but might become irritated and swollen from operative manipulation. In these cases, the presence of a transurethral catheter prolongs this irritation.
  • the suprapubic system of urinary drainage allows for easy determination of a patients ability to void voluntarily.
  • prior art suprapubic catheters are inserted through a trocar or a large needle, which serves as a guide for insertingthe more narrow catheter tubes.
  • the trocar method has an obvious disadvantage of producing a large wound when insertion is made by the trocar through the bladder, thereby increasing the possibility of urine leakage from the bladder into the peritoneum because of the loose fitting catheter tube.
  • Both the trocar and the needle method of insertion cause an extremely narrow catheter tube to be introduced into the bladder, increasing the likeihood of a plugged or blocked tube, due to the coring of tissue resulting from insertion and/or from obstructions occurring within the bladder.
  • the collection bag at the distal end of the assembly must be removed or disconnected in order to administer medication or to irrigate the bladder.
  • Still another object of the present invention is to provide a complete suprapubic catheter system having all the features outlined above using pre-attached and yet separable drainage connectors and a removable stylet in which the apposition of catheter to stylet distance relationships is maintained by a locking mechanism at the adapter end of the stylet.
  • a suprapubic catheterization system wherein a suprapubic catheter has an internal elongated stylet that is a combination of a trocar which prevents tissue coring during insertion of same into the bladder, and a hollow cannula having at least one side opening on the lower end thereof that may coincide with a side opening on the lower end of the thin walled catheter tube external to it, or the opening may be made on the side of the trocar projecting just below the catheter tip.
  • the openings on the cannula and catheter tube permit urine to enter at the proximal end thereof, thereby indicating that both the trocar and the tip of the catheter tube are positioned correctly well inside the bladder.
  • the internal stylet can then be removed and a routine hook-up of the pre-connected yet separable catheter system can be accomplished, leaving a catheter tube within the patients bladder that has an advantageously large drainage lumen, and an advantageously tight fit between the catheter and the penetrated tissue.
  • the bladder can be irrigated and/or medication can be administered thereto through the external portion of the assembly without interfering with the collection bag by simply unlocking and disconnecting the assembly at the catheter hub and inserting a luer fitting syringe therein for irrigating a blocked catheter or the like.
  • a slidable collet type locking mechanism can be positioned on the outer catheter tube prior to insertion into the bladder for stabilizing this internal stylet type of catheter. The locking mechanism is slid down the external catheter to a desired and convenient length and locked in place,

  • FIG. 2 is a partial view of a catheter hub used in this invention. 7
  • FIG. 3 is a sectional view of the catheter system shown in FIG. 1, but in an assembled position;
  • FIG. 4 is a sectional view of the catheter system of this invention after the puncture has been made in the bladder, the internal stylet has been removed and the drainage tube leading to the collection bag has been connected to the catheter hub;
  • FIG. 5 is a perspective view of the locking mechanism used in this invention.
  • FIG. 6 is a sectional view of the locking and stabilizing mechanism of this invention.
  • FIG. 7 is a sectional view of the catheter system of this invention having a syringe used therein for irrigation purposes;
  • FIG. 8 shows a sectional view of another embodiment of this invention.
  • FIGS. 1, 2 and 3 of the drawing show a complete suprapubic catheter system 10 wherein a catheter tube 1 l is bonded to a catheter hub 12 and has an elongated internal stylet 13 situated therein.
  • the stylet 13 serves as both a trocar or puncturing device and a hollow cannula, and has a plurality of side openings 14 thereon near the end or pointed portion of the stylet 13.
  • the openings 14 on the stylet 13 correspond to, and are in congruous relationship with, a plurality of openings 14a on the catheter tube 1 1, when the stylet is fully inserted in the tube 11 just prior to puncture of same into a patients bladder.
  • the stylet 13 has a sharp tip or point 15 on the closed end thereof to facilitate its insertion into the bladder area. Tissue coring upon insertion is prevented with this trocar type stylet and the openings 14 and 14a thereon advantageously permit the show of urine flow at the proximal end of the assembly, indicating that both the trocar and the catheter tube are positioned well inside the bladder.
  • the stylet 13 should have an external diamer ter slightly less than the internal diameter of the catheter tube 11, so as to permit the stylet 13 to be inserted snugly into the catheter tube 11.
  • the end portion of the tube 11 can advantageously have a coiled configuration to assist in the retention of the catheter intracystically and is tapered so as to facilitate the incision.
  • a rather rigid plastic sleeve 16 can be slipped over the coiled tube 11 to straighten it out and facilitate the insertion of the stylet 13 therethrough.
  • the top of the stylet l3 is'capped with a plastic head 17 or the like that facilitates its handling, and has a cutout therein having a shape similar to an inverted L as at 18, for locking with the protuberance 19 on the catheter hub 12.
  • This key lock at 18 and 19 will hold the stylet 13 in its extended position for the puncturing step and for insertion of the stylet l3 and the tube 11 into the bladder.
  • the stylet 13 can then be unlocked, disconnected and withdrawn.
  • the locking device 20 can advantageously be of a collet-type consisting oftwo parts that are slid over the catheter tube 11 having the internal stylet 13 therein.
  • the male part 21 has at least one small slit on the tapered portion thereof that permits this male part 21 to squeezably fit into the female part 22.
  • This locking device is slid down the external catheter to a desired and convenient length prior to insertion and is locked in place, and can be used as a base for securing the catheter to the body of the patient.
  • Other slidable locking mechanisms can also be used, such as eccentric types, taper types or the like.
  • the catheter is attached to the patients body and a routine connection of the catheter tube to the collection bag is accomplished, as shown in FIG. 4, by attaching a drainage tube 23 to the catheter hub 12 via an inter-connecting cap 24 having an inverted L cutout thereon that key locks with protuberance 19 on the catheter hub 12.
  • the interconnecting cap 24 can be molded with the catheter hub 12 as a single unit joined together by strap 26 and can have a thumb tab 24a to facilitate its removal.
  • the stylet head cap 17, the inter-connecting cap 24 and the catheter hub are preferably of a plastic material, although other materials, such as rubber elastomer or the like, can be used with similar results.
  • the catheter is secured to the body of the patient using the locking device 20 as a base for doing so.
  • the internal stylet type catheter shown herein advantageously permits the catheter tube 11 to have a large drainage lumen.
  • This physical structure is advantageous principally because it lessens the likelihood of blockage occurring therein. Also, blockage which might nevertheless still occur can be removed more easily therefrom compared to a smaller drainage lumen since the same suction force exerts more pressure on the larger cross-sectional area provided by this invention. Additionally, given the same size puncture for an inner catheter (small lumen) as for the external catheter of this invention (large lumen), a tigher fit (liquid seal) is achieved between the catheter and the surrounding tissue thereby decreasing the possibility of urine leakage from the bladder into the peritoneum because of a loose fitting catheter tube.
  • FIGS. 5 and 6 better demonstrate the locking mechanism 20, wherein the tapered male part 21 squeezably fits into the female part 22. At least one slit 27 is provided on the tapered portion of the male part 21 to facilitate and insure a tight fit within the female part 22.
  • at least one side of the locking device has a flat surface that can lay on the body or abdomen of the patient and should have a winged portion 28 thereon for more advantageously securing the device to the patient.
  • the device 20 may also be provided to have adhesive material 29 on the bottom or flat surface thereof, covered with release paper 31 or the like, so that once the device 20 is locked in the desired position the release paper 31 may be peeled therefrom, and the device can be adhesively attached to the patient without requiring any further securing means.
  • the winged portion 28 may be utilized as a hand grip during insertion, and may then be taped on the abdomen of the patient for securing purposes.
  • Medication can be administered to the bladder, and irrigation procedures can be provided therefor by simply unlocking and disconnecting the drainage tube 23 from the catheter hub 12 as shown in FIG. 7, and inserting the luer end of syringe 40, into the tapered opening 32 on the catheter hub 12. After the irrigation steps have been performed, the syringe 40 is removed and the drainage tube 23 once more connected and locked to the catheter hub 12 as previously described herein.
  • FIG. 8 there is another embodiment of this invention shown wherein a catheter hub 41 has a catheter tube 42 extending from the bottom thereof through which an internal stylet, as previously described herein,
  • the removable cover 44 can advantageously have a snap-ring construction or the like, having a thumb tab 48 thereon to facilitate the opening and closing thereof.
  • the bottom of the hub 41 can advantageously be covered with a foam or cushioning material 45 for sitting comfortably on the patients body and can also be provided with a layer of adhesive material 46 for securing the catheter to the patient.
  • the adhesive material 46 may be covered with a sheet of release paper (not shown) for convenience and ease of handling prior to use.
  • the catheter tube used in this invention may be of any plastic material, such as polyethylene, silicone, polyvinyl, teflon or the like and should conform to certain size limitations consistent with the requirements and objects of suprapubic catheterization.
  • the catheter tubing useful in this invention may have an internal diameter ranging from 0.030 inch to 0.125 inch, and an external diameter of from 0.050 inch to 0.145 inch. It is presently preferred that the tubing have an inner diameter of 0.067 inch and an external diameter of 0. 107 inch.
