Definitions

  • the present invention relates to a protective sheath for a catheter for carrying out intracorporeal measurements.
  • Catheters are basically tubes or tubes with which hollow organs, such as bladder, stomach, intestine, vessels, etc., but also ear and heart can be probed, emptied, filled or rinsed. This happens for diagnostic or therapeutic reasons.
  • catheters with pressure sensors are known, which are used in particular in urology and gastrology.
  • Pressure sensors are to be measured either constrictions, abnormalities or the closing force of so-called sphincter muscles. Until a few years ago, these measurements were made using catheters that could be used multiple times. As the time and effort for cleaning and
  • Reusable catheters consist of a plastic tube, in which several pressure sensors are distributed over the length, and their electrical leads are guided centrally through the tube to the outside.
  • the entire reusable catheter must therefore be cleaned and sterilized after each use. In contrast to the widespread view that this is more expensive because of the associated work or time is not correct.
  • the fact is, however, that the pressure sensors are destroyed during the sterilization process with the highly sensitive catheters with thin traces to the electrical pressure sensors due to incorrect handling. For this reason, the applicant has set itself the task of creating a protective sleeve, for a catheter for performing intracorporeal measurements.

  • Such abnormalities can be any kind of cross-sectional changes. As soon as the collar 115 reaches such a cross-sectional change, in particular cross-sectional constriction, the pressure on the collar is increased and the gel directs this pressure into the area of the pressure sensor window 11 so that the pressure sensor can respond.
  • the inventive protective cover 1 can also be used for gastrological examinations, in which case the dimensions of the protective cover 1 are much larger. In addition, in a gastrological examination not only the length is much greater, but also correspondingly much more Measuring points are used with appropriate pressure sensors. For gastrological use, up to 36 pressure sensors with corresponding pressure sensor windows can be easily attached here. Since the inner lumen 42 can have a considerable diameter, the corresponding number of electrical conductors can accordingly also be accommodated therein without difficulty.
  • FIG. 10 also shows the possibility of attaching contact surfaces which can be attached externally to the protective cover. These contact surfaces serve to detect the leakage of already minimal amounts of urine or rinsing solution from the bladder into the ureter.
  • These contact surfaces 120 can preferably be applied to a self-adhesive carrier film 121 by means of coating. Likewise, the conductor tracks from the contact surface 120 can be attached to the carrier foil 121.
  • These interconnects 122 extend from the contact surfaces 120 to the distal end of the protective sheath, where these interconnects are tapped in order to be able to measure a corresponding passage signal.
  • An insulating and protective cover layer 123 will be applied over the printed conductors 122 and partly over the edge region of the contact surfaces 120.
  • This cover layer 123 may, for example, be a corresponding insulating lacquer.
  • the self-adhesive carrier film with the conductor tracks 122 of the contact surfaces 120 and the cover layer 123 mounted thereon can be left after completion of the protective cover 1 outside on the hose 4 at the desired locations. Normally, one will attach the contact surfaces 120 slightly distanced distally from the pressure sensor window 11, which is furthest away from the proximal end.
  • FIGS. 11 and 12 A particularly preferred embodiment of the protective cover 1 is shown in FIGS. 11 and 12.
  • the essential difference here is that the common wall portion 44 is here designed as a flat surface. This has the advantage that the known inherent rigidity of a rounded surface is reduced in this area. Also, in this embodiment, a corresponding Drucksensor pre 11 attach easier and more defined. The subsequent attachment of a cover film or a shrink tube section over the region of the pressure sensor window 11 is not affected thereby.
  • the thinnest region 48 is easier to make so thin that, if necessary, even a pressure sensor window 11 is unnecessary.
  • this thinnest region 48 thanks to the planar course over a substantial distance, is considerably larger than in the embodiment of the protective cover 1 described above.
  • the inner lumen 42 by an inner cylindrical wall.
  • the cross section of the inner lumen 42 is designed rectangular.
  • This rectangular or square cross-sectional shape has additional advantages.
  • the pressure sensor which can be pushed into the inner lumen 42 with its pressure-sensitive surface can also be designed such that it comes to lie exactly flat under the common wall portion 44 and thus below the thinnest region 48 of the protective cover 1. In such an embodiment, therefore, a mechanism by means of which the pressure sensor after insertion must be rotatable is unnecessary. The orientation of the pressure sensor on the pressure sensor window 11, or on the thinnest portion 48 results automatically with correct introduction of the reusable pressure sensor.
  • the pressure sensor can be marked in color accordingly. Of course, other optical markings for orientation may be appropriate. Also, the rectangular or square cross-section of the reusable pressure sensor with the corresponding lines causes this less prone to buckling. The skilled person will therefore prefer this latter embodiment of the protective cover.

Abstract

L'invention concerne une gaine de protection (1) sous forme d'un tuyau souple (4) présentant une lumière extérieure (40) et une lumière intérieure (42) disposée excentriquement à l'intérieur de la lumière extérieure. La lumière extérieure (40) est limitée vers l'extérieur par une paroi extérieure (41), et la lumière intérieure (42), par une paroi intérieure (43). Les deux parois (41) et (43) se rejoignent de manière à former une partie de paroi commune (44), la partie de paroi commune (44) présentant une zone très mince (48) qui se comporte pratiquement comme une membrane. Éventuellement, des fenêtres de détection de pression (11) peuvent être ménagées dans la zone (48), dans la partie de paroi commune (44). Ces fenêtres de détection de pression (11) sont ensuite refermées par un film mince d'une grande souplesse. Ceci peut être avantageusement réalisé au moyen d'un tuyau souple constitué par un film rétractable. Un cathéter à détection de pression réutilisable peut être introduit dans la lumière intérieure (42), cependant qu'une solution de rinçage peut être introduite dans le patient par la lumière extérieure (40). Grâce à la gaine de protection selon l'invention, des cathéters à détection de pression réutilisables peuvent être utilisés plusieurs fois sans qu'une stérilisation soit requise. La gaine de protection (1) est remplacée après chaque usage.
