Definitions

  • the invention relates to a stopcock.
  • the invention is based on considerations with regard to steam-sterilized tracheal ducts and is also described in the following mainly in connection with them, the invention is, however, not restricted to this.
  • a blocking cuff tracheal tube is designed to be inserted into a patient's trachea. The blocking cuff is then inflated until it lies tightly against the inside of the trachea, thereby creating a seal so that, for example, segas can be directed into the lungs.
  • a supply hose is used for inflating and later emptying the blocking sleeve, which has at its end a conically widening connecting piece for attaching an injection syringe, which serves as a pump; the connection piece is the known Luer connection. After the syringe has been withdrawn, the supply hose having been disconnected beforehand, a stopper is placed on the connection piece so that the blocking sleeve remains in the inflated state.
  • the stopper Before the tracheal tube is removed, the stopper, which is held captive, is pulled. If the tube with all the parts belonging to it is made of heat-stable material, it can be steam-sterilized and thereby reused. In steam sterilization, a vacuum is generally first used to remove residual air from cavities, so that the steam reaches all surfaces of the object to be sterilized all the more quickly and effectively. So that the blocking sleeve cannot be destroyed by air residues contained in it when the vacuum is applied, the above-mentioned closure of the supply hose must be open.
  • Closures are already known which contain an automatic valve which is opened when attached to the syringe and closes when the syringe is withdrawn.
  • these one-way valves cannot be opened before sterilization, but must be withdrawn from the supply hose so that the air can escape from the blocking sleeve when the vacuum is applied.
  • the invention is based on the general object of providing a shut-off device which can be used in the known tract tube and can facilitate its use.
  • the invention is not intended to be limited to this application.
  • the tracheal tube for which the invention can be used can in particular be a tracheal tube as described in the applicant's German patent application P 41 15 497.5. By means of this reference, the entire content of the cited patent application is made the content of the present application.
  • the present invention also extends to a tracheal tube with the features mentioned in detail above, in particular also to a tracheal tube according to the patent application mentioned, which has a stopcock according to the invention as a shut-off device.
  • the shut-off valve can be reused several times because its tightness does not affect it due to the heat.
  • e- • detent is provided for the rotation position in the open and locked position
  • the rotary movement can be smooth on the one hand, on the other hand the respective rotary position is secured and thus does not inadvertently change the respective rotary position is, in particular when the shut-off valve is blocked, around the blocking sleeve in the trachea to keep a patient's inserted tube inflated.
  • a material that can be steam-sterilized several times without interference is polyamide.
  • Polysulfone can be steam sterilized far more often.
  • a combination can be advantageous in which the housing in which the plug is rotatably supported is made of polyamide and the plug is made of polysulfone. Both parts are produced in an injection molding process.
  • the polyamide which is easier to deform elastically compared to polysylphone, can also perform sealing tasks so that the shut-off seam can consist of exactly two parts, namely the plug and the housing.
  • seals which consist of heat-stable, solvent-resistant material .
  • the material is preferably resistant to halogenated hydrocarbons, which include numerous solvents used in the medical field, but which also include anesthetics, so that the seals are then sealed against these anesthetic gases.
  • Seals can be arranged in such a way that they bring about a seal with respect to the connections when the shut-off valve is in the blocked position.
  • rings special O-rings on a suitable holder are used for this purpose of the chick, especially on bolt-shaped projections . , so that the assembly is facilitated.
  • acrylonitrile-butadiene rubber (Perbunan) is preferably used as the material for the seals.
  • the plug is advantageously held in the housing by an elastically deformable projection, for example an annular projection of the housing.
  • the housing consists of a relatively easily elastically deformable material (polyamide), this projection and the projections required for the above-mentioned detent can protrude further than in the case of a material which is only slightly deformable, such as polysulfone; in the case of the last-mentioned material, the projections must be correspondingly smaller.
  • FIG. 1 shows a longitudinal section through an exemplary embodiment of a shut-off valve in the locked state
  • FIG. 2 shows a cross section along the line II-II n Figure 1.
  • a housing 1 has two tubular connecting pieces 3 and 5, which form channels of connections 7 and S and, aligned with one another, open into a circular cylindrical interior 10 of the housing 1.
  • Arranged in the interior 10 is an essentially circular cylindrical movable valve part, the so-called plug 12, which can be rotated about its longitudinal axis, and this has a transverse bore 14 which, in the blocking position shown in FIGS. 1 and 2, with the connections 7 and 8 is not connected, however, when the plug 12 has been rotated 90 ° in any direction, the two connections 7 and S connect to one another.
  • the surface of the plug 12 is recessed in a ring shape, a bolt-shaped projection 20 remaining, and an O in each case on this projection 20 - Ring 22 put on.
  • the projection 20 is circular-cylindrical and, in the blocking position of the shut-off valve, runs coaxially to the longitudinal axis of the connections 7 and 8.
  • the two O-rings 22 are under pressure between them inwards (to the axis of rotation of the kukens) supporting surface 26 and the circular cylindrical wall 28, which delimits the cylindrical bore 10, and thus seal the connections 7 and 8 with respect to the interior 10.
  • the O-rings 22 lie outside the contour of the connections 7 and 8 in their area directly adjacent to the plug, ie they are not visible through the connections 7 and 8.
  • a further O-ring 32 is provided, which is arranged in an annular groove 33 of the plug 12, the axis of this annular groove together with the axis of rotation of the plug falls.
  • This further O-ring 32 seals the interior 10 from the surroundings of the shut-off valve.
  • the plug has an annular bead 36 projecting slightly radially outwards, which is bevelled downwards and upwards and, when the plug is inserted into the housing 1, has an annular bead 40, which in the Housing 1 is formed, elastically pushes outwards.
  • This bead 40 is located above the furthest point of the bead 36 when the chicks are fully assembled and thus holds the chick captively but can be dismantled without being destroyed.
  • the plug In order to create a detent for the rotary position of the plug 12 both in the blocking position shown and in the passage position rotated by 90 °, the plug has a total of four detent projections 44 which protrude radially with respect to its axis of the gland, each around 90 ° offset from each other, 1 and engage in corresponding locking recesses on the inside of the upper end region 46 of the housing 1. These locking depressions are not shown because they have only an extremely small depth compared to the drawing.
  • the housing 1 consists of a polyamide, namely the polyamide 610 S3K from Ultramid commercial and experimental products
  • the plug 12 consists of a polysulfone, namely the polysulfone Mindel S 1000 from Amoco Chemicals GmbH, Düsseldorf
  • the O-rings 22 and the further O-ring 32 consist of acrylic nitrile butadiene rubber (Perbunan).
  • the total length of the shut-off valve between the ends of the two connecting pieces 3 and 5, which are provided with conical plug connections (Luer connections), is approximately 40 mm.
  • the diameter of the interior 10 is approximately 6 mm.
  • the distance between the free ends of the wing-shaped projections 16 is approximately 25 mm. The remaining dimensions can be found in the drawing, which is approximately to scale.
  • the housing 1 is injection molded from polysulfone, its flow properties differing from polyamide must be taken into account, as well as the fact that polysulfone is less easily deformable elastically.
  • shut-off valve shown allows them to be steam sterilized 20 times in an autoclave using a vacuum at a temperature of 130 ° C. and lasting 30 minutes without any loss of tightness.
  • polysulfone for the housing, the number of possible sterilizations is greater.
