Definitions

  • Urinary incontinence is a particularly long-recognized medical problem and relates to the inability of a subject to control voluntarily the elimination and function of the bladder, which problem can result from numerous causes.
  • This invention relates to an involuntary urine control valve apparatus, system and a method for the control of urine, which involuntary urine control valve apparatus is adapted to be inserted a short distance within the distal end of the urethra of a subject.
  • the invention relates to an involuntary urine control valve apparatus adapted to be inserted a short distance within the distal end of the urethra of a subject, and which valve apparatus comprises a urine control valve means, which valve means moves between an open, urine flow position which permits the flow of urine from a subject, and a closed, urine stop position which prevents the flow of urine from a subject, the control of which valve means is controlled by the subject.
  • the urine control valve means includes an outer, generally cylindrical jacket having an external diameter which is adapted to fit slidably and comfortably within the interior of the urethra, having an inlet at the one end and an outlet at the other end, generally with the inlet and outlet aligned within the jacket.
  • the jacket includes about the other end of the jacket a membrane collar-type means, which is adapted to move radially between a fluid-inflatable position, which places the membrane in snug contact with the internal wall of the urethra of a subject in order to stabilize the jacket in position within the urethra, and a collapsed, deflated position to permit the insertion into or withdrawal from the urethra of the jacket.
  • the jacket includes a valve means, typically on the external one end thereof available to the subject, and a connecting passageway so as to supply or remove fluid to the collar membrane means, to provide for the movement of the collar means between said positions by the actions of a subject.
  • the jacket includes an outwardly, radially extending flange from the one end and extending slightly outwardly from the open distal end of the urethra, generally and preferably curved and having a smooth, contoured, external surface so as to retain the jacket at the open distal end of the urethra.
  • the control valve means includes a head means, secured typically disposably at the outlet end of the jacket, with the head means having at least one outlet passageway and typically a central passageway surrounded by a plurality of other spaced-apart passageways to permit the flow of urine outwardly from the subject, and from the interior of the jacket.
  • the control means also includes a tension-biased, magnetically-activated ball valve within the jacket, the ball valve adapted to move between a tension-biased, closed position to prevent the flow of urine from the inlet to the outlet and an open position against a valve seat, actuated by a magnet, to permit the flow of urine from the inlet to the outlet .
  • the valve seat is positioned generally adjacent and about the inlet end of the jacket at the other end, and the ball comprises a metal ball, typically with a thin coating of a biomedically-acceptable polymer, and which is tension-biased, such as by the employment of a spring of suitable tension.
  • the tension-biased ball valve is characterized by sufficient tension in order to close the ball valve against the ball valve seat, and insufficient tension to prevent the opening of the ball valve if the bladder is full and requires urine release, and insufficient tension to prevent the movement of the magnetic ball valve from the ball valve seat to the open position on the ball valve seat unless it is activated by the influence of the magnetic force of an external magnet means.
  • the involuntary urine control apparatus also includes separate external means, such as a finger-operated fluid pump operated by the subject, to inflate the jacket collar membrane means into its inflatable, stabilizing position while the valve means, generally external at the one end of the jacket, also permits the deflation of the collar and membrane means, by the insertion of a small rod or pin into the valve to move the check ball away from the valve pump opening, releasing the fluid, to permit the removal of the jacket as required.
  • the control apparatus also includes a separate, externally operated magnet means employed by the subject, and when placed adjacent the control valve means, permits the magnetic field of the magnet means to activate the magnetically-activated ball valve means and to move it from the closed to the open position as desired by the subject .
  • the urine control valve apparatus would have a generally disposable and removable head containing an outlet passageway for the passage of urine and which also contains a plurality of generally uniformly, longitudinally, slightly inwardly extending guide fingers about the head of the valve.
  • the fingers may be inserted in the one or distal end of the valve jacket, and may be secured therein so that the head and guide fingers may be periodically removed as desired by the subject and replaced.
  • the involuntary urine control apparatus of the invention with inlet and outlet openings for receiving, conducting and discharging fluids, typically urinary fluids from the urethra, is designed to hold its position within the distal end of the urethra of a subject and has a discharge outlet positioned slightly outside of the distal end of the opening of the urethra.
  • the apparatus is held in a selected position a short distance within the end of the urethra by a precisely manufactured valve jacket, which includes a ball valve seat and a fluid control membrane or collar, which on inflation secures the valve jacket to the inner surface of the individual urethra wall, and wherein the valve jacket contains an outwardly extending flange positioned adjacent the distal end of the urethra, thereby stabilizing the urine control valve in the selected position.
  • the control device typically would include identical internal parts for both male and female users, and would comprise a urine control spring-guided ball valve, spring or tension-biased, necessary for a standard magnetic control operation to open and close the valve.
  • the urine control spring guide attached to the head is threadably secured at the large end and secured to the head and spring guide fingers in an exact position in the distal end of the valve jacket for the tension-biased magnetic operation of the ball valve.
  • the tension-biased ball valve maintains the valve closed against any fluid leakage, and any minor pressure from the bladder.
  • the tension-biased ball valve is designed also to relieve any excess pressure around the bladder as a safety function, as well as to be operated by the externally operated magnet.
  • the valve jacket comprises, on its outer end or distal end extending around the circumference, an enlarged diameter, inflatably designed fluid control chamber extending from one to the other end from the external outer end to the membrane or collar apparatus, so that the inflated collar means provides for positively positioning the control apparatus for optimum control by a hand-held permanent magnet by the subject.
  • the elongated chamber is located in the outer surface of the cylindrical valve jacket, and the external diameter of the outer jacket is confined to an exact, precise diameter as by a urethral measuring tool, as hereinafter described.
  • the outer chamber during the insertion into the urethra, has no volume of fluid within the collar or membrane means, as in a deflated position, so that the control apparatus outer chamber may be easily and comfortably inserted by the subject, so that the flange is positioned against the urethra opening.
  • control apparatus When the control apparatus is completely inserted within the urethra up to the flange, it may now be ready for the inflation of the collar or membrane means by slight pressure to fill the membrane collar with fluid, such as a liquid or gas, to make positive, absolute contact with the inside wall of the urethra, which operation is done by the subject, after having the initial fitting of the outer jacket determined by a physician or the subject himself, by means of a urethral diameter measuring tool, as hereinafter described.
  • fluid such as a liquid or gas
  • a fluid is supplied to the outer chamber membrane collar from a small diameter capillary tube, connected to the outer chamber and encapsulated in the outer wall of the jacket, through a check valve to a point that is positioned to connect with, for example, a finger pump on the discharge end of the flange of the jacket.
  • the subject may use a finger pump or ball-type gas or liquid pump connected to the valve of the capillary tube passageway, so that the patient slowly pressurizes and inflates the membrane collar means to seal the other end of the jacket comfortably within the urethral walls, thereby completely stopping any flow or drip of urine past the jacket.
  • the control valve is not in flow position until the subject ascertains the need to urinate.
  • Urination is accomplished by the subject by simply placing a permanent magnet in a predetermined position for the magnetic field of the magnet to move the magnetically-activated, tension-biased ball valve off the ball valve seat, to a position against a ball valve stop within the spaced-apart spring guide fingers hence to permit urine flow, like a normal urinary function, from the inlet to the outlet, and to discharge from the distal end of the valve head.
  • Urine flow is terminated by simply removing the permanent magnet, and the influence of the magnetic field from the magnetically-activated, tension- biased ball valve, so that the tension of the ball valve returns the ball valve to the ball valve seat, to stop urine flow.
  • the manufacture and use of measuring dowel tools are used to measure properly the individual subject's urethra. These tools are comprised of dowels, a temperature control chamber and sterilizing device as hereinafter described.
  • the urine control apparatus, system and method have numerous and significant advantages over prior art devices for the control of body fluids, and particularly urine control valves of the prior art.
  • the control valve of the invention is precisely fitted and held directly to the inside diameter of the urethral wall a short distance from the distal end of the urethral opening; such as, for example, within one-half to one inch of the distal end. Therefore, there are no tubes, balloons or flushing tubes required.
  • the control apparatus permits the subject to control the insertion, operation, withdrawal, dismantling, cleaning and disposal, and also permits the subject to apply antimicrobial cream to the surface of the control apparatus components.
  • a removable valve head with the tension-biased ball valve can easily be removed, cleaned and re- inserted by the patient, and periodically removed and disposed of to employ a new, clean valve head.
  • the control valve is simple in manufacture, operation and components, and comprises only four component parts; an outer jacket, a spring, a ball valve and a valve head for insertion into the jacket.
  • the externally hand-held permanent magnet to operate the ball valve and an external fluidic pump are all controlled by the patient .
  • the control apparatus is also fitted precisely to the inside diameter of the urethra of a subject, and it is fitted with a deflatable and inflatable collar, so designed to be secured to the inside wall of the urethra in a gentle, comfortable manner, so as to handle pressure without movement, such as twice the pressure of the bladder urine, thereby stabilizing the control valve in its position.
  • the control apparatus is so designed that the only surface of the control apparatus to come in contact with the patient's urine when the valve is in the closed, urine stop flow position is the end of the jacket and part of the ball valve.
  • the ball may be coated with an antimicrobial cream for insertion within the control apparatus.
  • the control apparatus is so designed that the apparatus can be removed by the patient at any time, if required.
  • the control apparatus and system is also simple to design, is inexpensive and may be made of light weight, medically and biologically acceptable polymer material.
  • the ball valve typically comprises a metal, for example, a magnetic metal ball, generally stainless steel-coated with a thin coating of an inert plastic material, more particularly a fluorocarbon, such as teflon.
  • control valve would be coated with an antimicrobial cream and can be removed from the patient when needed. There is a minimum or very little chance of any microbial attack, since the only area of urine contact will be a small portion of the ball valve in the other end of the jacket within the urethra. Therefore, properly used and maintained, the control apparatus will remain sterile.
  • the control apparatus is located in a convenient place to be controlled by the patient, that is, typically a maximum of one inch in from the distal end of the urethra, to avoid any contact with the bladder. Generally and preferably, the jacket of the control device is precisely manufactured to the urethral size of the individual .
  • the control device is easily operated by an external, hand-held, permanent magnet which is easily stored in the pocket or handbag for immediate use, and the inflation of the membrane collar means by the control valve is easily accomplished by a simple, finger- operated air pump, and the collar means deflated easily by insertion of a pin or small diameter rod to move the pump ball off the seat in the valve pump at the outer end of the jacket .
  • the procedure for inserting the urine control apparatus is quite simple, and usually includes having the subject wash his or her hands thoroughly with surgical soap, and then wash the genital area, and remove the control valve from a sterile packaging bag, wherein the subject coats the outer surface of the control apparatus and the ball valve with an antimicrobial cream, and then slowly inserts the control apparatus with the membrane or collar means in a deflated condition within the urethra until the flange reaches the outer end of the urethral opening.
  • the subject Upon completion of the insertion by the subject, the subject slowly pressurizes with the finger pump, the valve, pumping fluid through the inner capillary tube passageway into the membrane or collar means to place it in an inflated position, until the jacket feels comfortably and securely in place within the urethra.
  • the subject With each pump operation, the subject holds the large flange at the end of the outer valve jacket and gently tries to remove the control device from the urethra. The subject may then continue pumping when there is a slight tension pulling the control apparatus until the control apparatus feels tightly positioned and stabilized within the urethra.
  • the urine control apparatus requires the precise measurement of the subject's urethra, which may be accomplished by any technique; however, a specially designed measuring tool and procedure has been developed to fit individually the subject's urethra.
  • the urethral measuring tool kit is designed to provide a plurality of dowels, each dowel designed to be inserted into a proper depth within the urethra to determine the size for maximal operation.
  • the measuring tools should be able to measure properly each subject's urethra over the entire length of the urine control valve apparatus, but generally not greater than about one inch from the distal end of the urethra.
  • the dowels of the tool kit should be selected and inserted in a sequence to be slowly enlarged to a proper fit and comfortable feel to the subject before actually forming and inserting the outer jacket.
  • the subject must be able to remove the measuring tool dowel as if it were the uninflated valve jacket, to install it with ease and comfort within the urethra.
  • the measurement will be employed to form the outer jacket which will enclose and seal the ball valve inside the jacket.
  • the urethra is malleable, pliable, flexible and very sensitive to heat and cold, and will tend to stretch or return to its normal size. It is therefore necessary for all tools and instruments to be kept, maintained and used at body temperature.
  • the measuring tools and dowels should be highly polished and have a smooth surface over their entire useful length, and insertion of the measuring tools or dowels should be done with the same tool with which the outer valve jacket will be installed, and the measurement tools should be sterilized during handling periods.
  • the measuring tool kit generally comprises 15 to 20, or more or less as desired, cylindrically shaped dowels, generally up to about an inch long, for example, 0.750 inches, along with diameters ranging from 0.25 inches to .335 inches in diameter and generally are increased in selected increments, such as 0.05 inch diameters and stored in sterile packages at body temperature. Once the exact diameter of the urethra is determined, the subject may then install the properly dimensioned outer valve jacket within the distal end of the urethra.
  • Measuring tools or dowels of the urethra measuring kit generally comprise a smooth, round, biocompatible surface, made of a biomedically-acceptable material, with a slightly diameter-enlarged cylindrical end, a short, generally cylindrical end extending essentially from one end of the dowel, the other end of the dowel being a smooth, curved surface, typically a handle, generally comprising a flange similar to the flange end employed in the outer valve jacket, having an outwardly curved surface, so as to mimic the outer flange of the valve jacket.
  • the urine control valve apparatus has been described in connection with the insertion in the end of the urethra for urine control, it is recognized that the control valve may be used for the control for other bodily fluids by insertion in other bodily fluid flow passages where subject control of bodily fluids is desired.
  • the urinary incontinence control apparatus and invention may be easily employed with both male and female subjects, but will be described for the purposes of illustration only in connection with certain illustrated embodiments; however, it is recognized that those persons skilled in the art may make various modifications, changes, improvements and additions to the illustrated control valve system and method without departing from the spirit and scope of the invention.
