Definitions

  • the invention relates to a balloon instrument for natural and artificial body cavities, with a tube shaft and a supply tube, which is connected to a blocking sleeve, which forms a coherent annular space over its entire axial length, which is formed by end sides attached to the tube shaft and an outer peripheral surface ⁇ is limited.
  • a balloon instrument has become known from EP-0513 650 AI.
  • Balloon instruments of the known type are intended to be inserted into the body cavities of a patient and the blocking sleeve provided on the balloon instrument is then inflated until it lies tightly against the inside of the body cavity in order thereby to effect a seal. If a natural or artificial body cavity is to be dilated, the known cuffs are used to widen these spaces. If such a known balloon instrument is used, for example, as a tracheal tube, the blocking cuff is filled with air after the intubation. The blocking cuff then closes the space between the trachea and the breathing tube, so that the inspiration mixture can no longer escape and flows into the lungs.
  • Known cuffs are gas-filled, for example in the form of a ball or a roller, i.e. if these cuffs are used to seal a body cavity, the cuff presses the tracheal mucosa with increased pressure, for example.
  • the gas pressure must be set in the blocking sleeve so that a secure seal is always guaranteed.
  • the known blocking sleeves therefore lie over the entire axial length of the adjacent tissue.
  • a balloon envelope which is attached to a tube shaft with the side facing away from the patient and with a cylindrical part an irregular, uneven outer circumferential surface and an adjoining ziehamonica-shaped part.
  • the cylindrical part of the balloon envelope After being inflated, the cylindrical part of the balloon envelope is held firmly and sealingly in a body opening by the irregularly shaped outer peripheral surface.
  • the part of the balloon envelope which is folded in the form of a ziehamonica acts as a pressure-evacuation reservoir when inflated.
  • the known balloon geometrylelle lies on the adjacent tissue over the entire axial length of the cylindrical part. Protrusions and overhangs of the irregular outer circumferential surface are pressed into the tissue in a wedging manner. This can lead to considerable tissue stress if there is an increased gas pressure in the balloon envelope.
  • the object of the present invention is to improve the function of a blocking cuff of the known type, so that, for example, the tissue immediately adjacent to the blocking cuff is protected as much as possible.
  • the outer circumferential surface has an undulating, contiguous outer contour formed from individual rings spaced apart from one another.
  • the design of the blocking sleeve according to the invention has the essential advantage that it first gas-filled adjoins a fabric in a line and thus reduces the contact points on the fabric.
  • the blocking sleeve according to the invention lies tightly and under pressure on the adjacent tissue sections due to the pronounced profiling of the outer circumferential surface of the continuous annular space.
  • the profiling of the outer peripheral surface could also be achieved, for example, by the profiling being stamped into the material of the outer peripheral surface.
  • the adjacent tissue is no longer subjected to uniform pressure over the entire axial length of a blocking sleeve.
  • the outer contour of the outer circumferential surface of the blocking sleeve also prevents high partial pressure peaks on the adjacent tissue.
  • the axial extent of the annular space of the blocking sleeve is also limited, so that the pressure which arises in the annular space when inflated can act in a targeted manner in the radial direction. It is thus ensured that the wavy structure of the outer peripheral surface is retained regardless of the pressure. Fabric surfaces are therefore gently pressurized. strikes.
  • the blocking collar according to the invention acts like sealing rings connected in series in a sealing system. Cave spaces are not expanded directly over the axial length of a blocking sleeve, but only in sections.
  • the wavy outer circumferential surface of the blocking collar according to the invention is advantageous. If the wave crests and the wave troughs are rounded, the wave crests abut the adjacent body tissue very gently and local mucus can collect in the wave troughs, which can take over a further sealing function in a series connection of wave troughs.
  • the patient-side end of the blocking sleeve on the tube shaft runs outward, is firmly connected to the tube shaft and ends largely without a shoulder.
  • the outward run of the blocking cuff to the end of the tube shaft on the patient side ensures that the tube cuff merges into the tube shaft in a continuous course.
  • This course is supported by the fact that a groove is formed in the tube shaft in the region of the patient end, in which the blocking sleeve ends. This enables gentle insertion and expansion of body openings when the blocking cuff according to the invention is inflated, since the blocking cuff seals against edge areas of the body opening. can nestle.
  • the tube shaft advantageously has a tube armature in the axial direction, preferably a wire spiral armature. If a tube shaft has such a reinforcement, it can be made of a softer elastomer and can nevertheless be aligned in a directionally stable manner. Such a tube shaft is also not kinkable. The lumen in the tube shaft, which is defined by a hollow wire spiral, is therefore always sufficiently open, even in the case of strong curvatures of the tube shaft.
  • the balloon instrument according to the invention is highly flexible and it is also possible to select very soft, tissue-compatible elastomers for the manufacture of such a balloon instrument without this resulting in a deterioration in the function of the balloon instrument.
  • transition reinforcement is provided in the transition area between the supply hose and the tube shaft.
  • This transition reinforcement contributes to an improved safety of the balloon instrument according to the invention by ensuring that the supply hose remains firmly connected to the tube shaft even under heavy mechanical loads. The gas connection to the blocking sleeve is thus also better secured.
  • the transition armouring is preferably a hollow wire spiral which extends over a certain section into the supply hose and is also anchored over a certain section in the tube shaft itself. The desired flexibility remains in the transition area between the feeder via a hollow wire spiral, for example. Preservation hose and tube shaft received.
  • the tube shaft, a tube tip, the feed tube and the blocking sleeve can be made from different elastomer materials. This has the advantage that multiply sterilizable materials can be used, which can be stabilized by appropriate reinforcement if necessary. If, for example, additional reinforcement is provided only in sections, other sections of the balloon instrument according to the invention can be made of a harder elastomer material, which are firmly connected to softer, reinforced material.
  • a further advantage is provided if a control balloon is provided in the area of the free end of the supply hose, to which a shut-off valve connects. If the shut-off valve is made of a material that can be sterilized and thermally stabilized, the entire balloon instrument can be used several times because it can be sterilized after each use without any functional disadvantage.
  • a particular application of the balloon instrument according to the invention is the use as a tracheal tube.
  • the tracheal mucosa can be spared, in which the blocking sleeve according to the invention, viewed in the axial direction, rests only several times in a ring on the tracheal wall.
  • FIG. 1 shows a balloon instrument according to the invention with an irregular, preferably wave-shaped, outer circumferential surface, a tube reinforcement and a transition reinforcement to the feed tube, which has a shut-off valve;
  • FIG. 2 shows a partial section of the balloon instrument according to the invention from FIG. 1 with a wave-shaped blocking sleeve shown in cross section;
  • FIG. 1 shows with the reference numeral 10 a balloon instrument which is composed of a tube shaft 11, a supply tube 12, a blocking sleeve 13 and a tube tip 14.
  • the tube shaft 11 is made of a soft, tissue-compatible elastomer and is provided with a tube reinforcement 15.
  • the tube reinforcement 15 is here, by way of example, a hollow wire spiral which is completely encased in the tube shaft material.
  • the tube tip 14 has no reinforcement and is therefore made of a harder elastomer material.
  • the tube shaft 11 is firmly connected to the tip of the bus 14.
  • a standard connector 16 is provided, through which ventilation tubes can be connected gas-tight to the balloon instrument 10.
  • the supply hose 12 opens in the region of its end into a control balloon 17, to which a shut-off valve 18 connects.
