Definitions

  • the invention relates generally to novel construction for a urinary catheter tube heldon by a catheter hanger with associated device. More specifically, the present invention relates to a catheter hanger holding and protecting catheter and the catheter tube and the device outside of the body .In addition it relates further a urinary catheter tube clamp device that includes a backflow preventive tap valve that is located in the catheter tube between a proximal point catheter tube where it is connected of the catheter and outer opening of the catheter tube where there is the urine passing tap providing improved construction and a safer location relative to the prior art devices.
  • this invention is designed to keep away the catheter bag when patient or catheter wearer is working or participating in a special event.
  • valve While one prior art/types or inventions catheter disclosed a one-way check valve in the drainage lumen, the valve was located proximal to the insertion end of the catheter (US 7331949 B2). The placement and design of the valve were formulated primarily to retain any fluid that may be within the catheter during withdrawal and disposal. In this manner, the valve prevented fluid from flowing out of the withdrawn catheter onto the floor or more importantly onto the medical professional handling the catheter.
  • this valve design is only appropriate for the stated function and several drawbacks which has been corrected in the present innervation . First, because of the size and location of the valve, in the narrowest diameter of the catheter, the passageway becomes very susceptible to blockage. Second, the valve is located within the patient allowing the potential of drained material flow into the patient. Finally, if this valve configuration is used in a double or single lumen design, the catheter cannot be used for irrigation because the valve would block the flow of injected irrigation fluid.
  • Another art of catheter invention provides a novel construction for a catheter that includes backflow prevention in the form of a check valve(US 7331949 B2). Moreover some new catheters design that provides distal valve system and the drained fluid may always remain in the drainage container for several hours allowing the growth of harmful bacteria . There is therefore this new catheter design that provides for a backflow prevention that does not allow the flow of drained material to re-enter the body of the patient while also providing a positively locking assembly that further facilitates the delivery of irrigation to the patient should the need arise. In addition it provides drainage system without the drainage container and compression lock without being susceptible to blockage or narrowing of the tube lumen and keeping away from the potential of drained material for flowing into the patient and remaining for long duration .
  • Tru-flo-equipped catheter can be drained directly into a commode at the convenience of the patient.
  • the valve universally adapts to all Foley and Supra-pubic catheter systems. (Tru-Flo-Catheter-Valve/show/1329359).

  • To reduce commercial flora contacts to the outer distal orifice of the catheter there is an extended catheter tube in this device which drain urine to the distal orifice of the tube before it is discharged .Meanwhile two valves are fixed to the Catheter tube to stop back flow of urine to the bladder and it will reduce propagation of microbes upwards through the tube and connect with commensal bacteria flora through the catheter tube .

In this manner, a second entry port into the drainage lumen at a point upstream from the valve may be provided if desired to allow irrigation through the catheter as has been previously unknown in the art.
  • the only way to facilitate irrigation is through the use of a triple lumen catheter.

  • valve of the present invention is located in a section of the lumen where the cross sectional area is larger, it is less likely to become clogged by for example, crystals that may be suspended in the patient's urine. Accordingly, one of the objects of the present invention is the provision of a novel catheter construction that provides protection against the backflow of drained fluid. Another object of the present invention is the provision of a novel catheter construction that prevents that backflow of drained fluid from reentering the body of the patient being treated. A further object of the present invention is the provision of a catheter construction that can be employed equally with the various types of existing catheter configurations to prevent the backflow of drained fluid while further allowing the use of the distal central lumen for irrigation if necessary.
  • Yet a further object of the present invention is the provision of a catheter construction that prevents the backflow of drained fluid air or susceptibility to invade normal bacterial flora while including a positive interlocking mechanism for the attachment of accessories such as out let object for passing urine and urine collection EPB.

Abstract

Les patients ayant des cathéters urinaires à demeure à long terme ont des difficultés à porter et garder le sac de cathéter lorsqu'ils souhaitent bouger ou se déplacer. Cette gêne et cet inconfort pour les patients qui ne sont pas alités augmentent la dépression et l'anxiété.En outre, un cathéter à demeure prolongé entraîne une dystonie de la vessie et le patient doit avoir l'autorisation d'une période d'apprentissage de la vessie avant de retirer le cathéter.De plus, il y a un risque augmenté d'infection des voies urinaires.Les infections des voies urinaires associées à un cathéter (CAUTI) sont une source importante de morbidité et de mortalité dans les installations de soins à long terme. L'impact financier de l'infection est davantage pris en considération dans la gestion de tels patients, infection qui est causée par des bactéries ascendantes à travers le système de drainage fermé.Pour essayer de réduire cette ascension, on a envisagé un système de clapet à verrouillage intracathéter qui maintient un système fermé durant le changement de sac ou le souhait ultérieur de passer à une miction naturelle. En outre, il aide à détacher les sacs et le tube externe lorsque les patients ont besoin de bouger ou de se déplacer sur une longue distance.Cela permet d'éviter plus d'inconfort aux patients ayant un système drainé existant avec le sac de cathéter. Le concept est introduit pour le confort du patient et les CAUTI ont besoin d'être réexaminées.
