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.
- FIG. 1 shows the protective cover according to the invention with connected insertion stubs as a whole
- Fig. 2 shows the proximal end of the protective sheath on a large scale
- Fig. 3 shows the distal end with the inlet nozzle on a larger scale.
- Fig. 4 again shows the proximal end of the protective cover with different cutting lines.
- Fig. 5 shows the diametral section along the line DD in Fig. 4 is enlarged, as well as
- Fig. 7 shows the diametrical section along the line F-F.
- Fig. 8 shows a proximal end portion of the protective cover with a cover of the window in the region of a pressure sensor for a unidirectional measurement
- Fig. 9 the same for a multidirectional measurement.
- Fig. 10 shows a resistance measuring probe for attachment to the inventive protective cover.
- Fig. 11 time a particularly preferred embodiment of
- the inventive protective cover is designated overall by 1.
- the protective cover 1 has a proximal end 2 and a distal end 3.
- the entire length of the protective cover 1 is formed from a double-lumen tube 4.
- the tip or the proximal end of the protective cover 2 is usually closed.
- the distal end 3 of the protective cover 1 is with provided an introduction stub 5. Through the introduction nozzle 5, the corresponding reusable catheter 6 can be inserted.
- the catheter 6 usually has a plurality of pressure sensors, as well as the corresponding supply and signal lines. Since the actual catheter is not a direct part of the invention, it will not be discussed further.
- the proximal end 2 of the protective cover 1 is shown enlarged in FIG. It can be seen that the protective cover 1 is sealed by means of a hose closure 7.
- This hose closure 7 may be a pluggable plastic part, which is welded or glued to the hose 4 for safety's sake, or the hose fastener 7 may also have been simply closed by compressing the lumen
- a Spülö Stamm 8 is then available on the hose closure 7.
- a pressure measuring area 10 follows. In this pressure measuring area 10, which is Depending on the application extends over a shorter or longer distance, one or more pressure sensors are arranged.
- pressure sensors can in principle be arranged directly on an outer, common wall portion, which is designed so thin that this wall portion forms a membrane.
- the protective cover 1 must be made of a relatively strong plastic, so that then this outer, common wall portion, even if this is designed very thin and thus indeed forms a membrane, still be too little pressure sensitive. (SET?) In this case, you will provide in the pressure measuring range 10 more pressure sensor window 11. This will be discussed again later.
- an electrical resistance sensor 12 with corresponding conductor tracks 13, be attached. This will also be discussed in more detail later.
- the introduction nozzle 5 placed on the distal end of the protective cover 1.
- the tube 4 by means of a plug-in nipple 50, adapted to the two-lumen tube 4, plug-connected.
- the plug nipple 50 is thus part of the insertion stub 5, which is made entirely of plastic.
- the introduction stub 5 has a single or multi-stage, conically tapered insertion opening 51. Through this insertion opening 51 of the multiple-use measuring catheter is introduced. This conical insertion opening 51 thus facilitates the Introduction of the reusable catheter.
- a feed line 52 opens a lateral junction 53 at the inlet nozzle 5.
- an actuating lever 54 with which the inserted catheter probe relative to the protective cover 1 can be rotated in this to the sensors or align the sensor so that they pass in front of the or the pressure sensor window 11.
- the shape and design of the insertion stub 5 described herein is merely a preferred embodiment, which is based essentially on the known introducer, but of course other embodiments may be used. It is essential, however, that the plug nipple 50 of the protective cover 1 is designed accordingly.
- FIG. 4 the proximal end 2 of the protective cover 1 is shown, and the various sectional planes D, E and F are shown, which are illustrated in detail in FIGS. 5, 6 and 7.
- the cross-section of the protective cover 1 is shown in section along the line DD of FIG.
- the cross-section shown here is in principle the same over the entire length of the protective cover 1, except for the area in which openings are provided.
- the protective cover 1 is a total of a single tube which is provided at the proximal end with a hose closure 7.
- This hose closure may be a glued-in pin, or just a weld or a glued lid.
- the tube 4 has an outer lumen 40 which is formed by an outer, preferably cylindrical wall 41. Within the outer lumen 40, an inner lumen 42 is eccentric. This inner lumen 42 is formed by an inner, preferably cylindrical wall 43.
- inner lumen 42 and “outer lumen 40” result, in principle, in that geometrically, in principle, a circle is inscribed with a smaller circle, the two circles run so that the smaller circle touches the larger circle practically at one point. This design results in the preferred embodiment, a sickle-shaped, outer lumen 40, and a circular cross-section lumen 42nd
- the cylindrical walls 41 and 43 of the two lumens 40 and 42 thus have a common wall portion 44.
- the central longitudinal axis 45 of the outer wall 41 and the centric Longitudinal axis 46 of the inner wall 43 define a plane which the common wall portion 44, along a line 47, which forms the thinnest point in the region of the common wall portion 44. At least in the area near the line 47, the wall thickness of the common wall portion 44 is so thin that a membrane 49 is formed. This area is indicated at 48 in the figure.
- the inner lumen 42 now serves to introduce a reusable probe catheter 6.
- the same lumen can of course also be used to introduce a Guidewires. If the protective cover 1 is in the correct position, the Guidewire can be pulled out and a measuring catheter 6 inserted.
- At least the region 48 of the membrane 49 is so thin that an underlying pressure sensor responds with sufficient accuracy. If this is not the case, 44 can in the area of the common wall portion
- Pressure sensor window 11 may be attached, as shown in the figure
- FIG. 6 shows a section through the tube 4 of the protective sleeve in the region of the pressure sensor window which extends substantially over the region 48 of the thinnest
- the protective cover 1 still the function of a
- a thin film 110 may be laterally welded or glued to the outside of the hose around the pressure sensor window 11 along the location 111. There this welding or gluing is not without problems, is preferably instead of only one piece of film 110 this film 110 sealed by a shrink tube 112.
- a shrink film tube may have a wall thickness of only a few hundredths of a millimeter. Preferably, such a shrink film tube wall thickness is selected in the range between two and ten hundredths of a millimeter.
- Such a shrink tube section 112 is in the shrunken state absolutely tight and under tension on the tube 4, and covers the pressure sensor window 11 absolutely sealed.
- a force F acting on the film 110 or the heat-shrinkable tube 112 now acts virtually unadulterated directly on the underlying pressure sensor.
- a pressure is thus detected which acts practically unidirectionally in the area of the pressure sensor window 11.
- Shrink film tube sections 112 and 113 with the gel 114 therebetween form a sleeve 115, which is shown in FIG. In this case, but you will be the two shrink tubing film sections along the
- the second, outer film tube section 113 need not necessarily be designed as a shrink film, but may be made of such a material, but you will not shrink this outer second film tube section 113 in any case.
- This solution is shown in detail in FIG. In contrast, in FIG. 8, the unidirectional solution described above, as already discussed with reference to FIG. 6, is again shown in a perspective view.
- FIG. 7 again shows the cross-section of the hose 4 cut in the plane according to the lines FF of FIG. 4.
- This cut lies in the scavenging opening area 8 and here in the area of two scavenging openings 9.
- the symmetry plane is denoted by S.
- 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.
