Definitions

  • the present invention belongs to the field of medicine and more specifically to that of accessories for performing intermittent clean bladder self-catheterization.
  • the object of the present invention is a device with a mirror that has an area that allows it to be attached to the urinary catheter and facilitates the vision of the person who has to perform the self-catheterization.
  • the intermittent clean bladder self-catheterization technique is performed by introducing a urinary catheter through the urethra until it reaches the bladder, allowing it to empty, and once the bladder is emptied, the urinary catheter is removed.
  • the urinary catheter is essentially cylindrical and hollow to allow urine to drain, it has 3 differentiated parts, the proximal end or area where the urine exits, the body and the distal end or tip that has holes to allow the urine to escape and is the part which first enters the urethra, until it reaches the bladder.
  • the proximal end of the probe is larger in diameter than the rest of the probe and is where the person performing the self-catheterization technique grasps it.
  • the catheter is inserted through the urethral meatus.
  • An aid in performing this technique is to use a mirror that allows you to see the meatus. It is normally used by women because the urethral meatus is hidden behind the labia majora and minora and is not seen with the naked eye as in the case of men, although sometimes obese men or other circumstances require its use. In order to see the meatus, men must retract the skin of the foreskin and women must open their lips with their non-dominant hand is habitually non-dominant and they need a mirror to see the meatus because apart from the maneuver of opening the lips, the meatus is not usually in view.
  • mirrors that are placed according to the mobility and preferences of the person who is going to do it. It can be on the bed, on the toilet seat or on the thigh of the person who is going to perform the self-catheterization by means of some type of restraint. These mirrors are difficult to position so that the urethral meatus can be seen, since the hands of the person performing the self-catheterization can make it difficult to see.
  • the inventor of the present application has developed a device with a mirror having a part that engages the proximal part of the urinary catheter.
  • the mirror By having the mirror attached to the proximal part of the probe, it allows to see through the distal end of the probe, which, as we have said before, is the first part that is introduced into the urethra and also allows to see the urethral meatus, which is by where the probe is inserted, so that the person performing the self-catheterization technique can visualize it and place the probe in the direction of it. In this way, the problem of the correct placement of other mirrors is solved, since the hands would not get in the way.
  • the present invention is directed to a device in which a mirror is integrated, which has a holding area for coupling to the urinary catheter.
  • Support area which, as its name indicates, supports the mirror. It has 2 faces: anterior, where the mirror is arranged, and posterior.
  • the thickness of the support area is preferably not more than 2-3 millimeters and it is desirable that it does not exceed 9-10 centimeters vertically and 5-6 centimeters horizontally.
  • the support area although it is a single piece, in turn has two differentiated parts: Upper area, essentially in the shape of a circular segment, although it can also be square or rectangular. In this area is where the mirror is arranged almost over its entire surface. Lower area, essentially rectangular in shape, defined as a grip area, the upper side of which is the lower limit of the mirror. This area is useful so that the person who is going to perform the self-catheterization can take it to direct the probe towards the urethral meatus, this is practical for people who have less mobility in their hands, or difficulty in grasping for any reason.
  • the coupling area of the device with the urinary catheter at its proximal end is located in its lower part and centered, it is essentially a perforated area in the grip area, shaped like a circular segment of variable radius depending on the probe to which it is attached. It can also be a different clamping system that is arranged in the grip area, type clamp.
  • b) Mirror which is on the front face of the support area. It can be square, rectangular or circular, the measurements should not exceed 5-6 centimeters in diameter horizontally. The thickness of the device in the part that has the mirror increases due to its presence, but for convenience it is convenient that it does not exceed 4-5 millimeters.
  • the inventor of the present application has verified in various tests carried out that the circular shape of the mirror and an approximate diameter of 5 centimeters favors the technique, since a larger diameter can hinder and a lower diameter makes visibility difficult.

  • This chord is centered on the lower side of the rectangle, thus leaving the coupling zone (1e) in the lower part of the assembly and centered on the vertical axis of the device.
  • the other well differentiated part is the mirror (1 f), circular in this case, 5 centimeters in diameter (L5).

Abstract

L'invention concerne un dispositif (1) à miroir (1f) et accouplement à une sonde vésicale (2c) pour aider à la mise en oeuvre de l'autosondage propre intermittent qui comprend une zone de support (1c) au niveau de laquelle sur sa face avant et essentiellement au niveau de sa partie supérieure est disposé un miroir (1f) de forme essentiellement circulaire, en outre au niveau de la partie inférieure de la zone de support (1c) est présente une zone de préhension (1d) et de manière essentiellement centrée la zone d'accouplement (1e), pour s'accoupler à la sonde vésicale (2c) à son extrémité proximale essentiellement au moyen d'un mécanisme de pression et qui fait qu'elle reste reliée comme s'il s'agissait d'une seule pièce. Grâce à l'intégration d'un miroir (1f), la vision directe sur la pointe du cathéter (2d) et le méat urétral est améliorée, la coordination pour son introduction dans celui-ci sans que les zones ne se touchent est plus facile.
