Definitions

  • the invention relates to a catheter coupling according to the preamble of claim 1.
  • Catheter couplings are known devices which serve to connect a longer, flexible catheter which has been introduced into the human body to another device, for example a syringe or a bacterial filter, after the insertion process.
  • another device for example a syringe or a bacterial filter
  • the end of the catheter protruding from the body is sealed and provided with an attachment through which the medication or the like can be injected.
  • DE-OS 31 02 142 describes a catheter coupling with a coupling! ungsgephaseuse, which has at one end a female LUEP. approach for connecting an injection syringe, usually with the interposition of a bacterial filter, and at its other end has a cavity in which a deformable clamping piece is located, which is penetrated by the end of the catheter .
  • This deformable clamping piece is compressible in the axial direction by means of a union nut, so that it tries to avoid the catheter surrounding it and thus clamps it.
  • Coupling injection syringes, bacterial filters or the like by means of the device described above is complicated and relatively time-consuming, since first the catheter end is fastened in the coupling with a union nut must and then the syringe or the like can be coupled via a LUER lock connection.
  • the vo ing invention is based on the hub to create a coupling that connects the catheter end with the syringe or the bacterial filter in a simple manner and thereby ensures a high degree of safety.
  • a particular advantage of this solution is the dual function of the LUER lock, in which the catheter end is pressed into the clamping piece and the device, for example an injection syringe or bacterial filter, is attached to the coupling piece.
  • the clamping piece is in the form of a sealing tube made of soft rubber or the like, which is pushed over the catheter and then circularly narrowed from the outside.
  • the inner catheter is hermetically sealed and at the same time held in place by the sealing tube.
  • the clamping piece for example in the form of a sealing hose, can be offset and fill the central bore of the male LUER attachment in the upper part and the conical bore of the female LUER attachment in the lower part. This results in an absolute seal on two independent diameters.
  • the clamping piece has a support ring at its lower end.
  • the support ring points a conical introduction at the bottom.
  • the support ring ensures that the sealing tube in the lower part is not squeezed together and allows easy insertion of the catheter even after repeated use.
  • the upper end of the clamping piece is tapered on its outer diameter and thus enables easy overlapping of the male LUER connector, which in turn contains a conical widening on its inner bore.
  • the coupling housing has a male LUER approach at the catheter outlet.
  • the male LUER approach By attaching the male LUER approach to the coupling, it can also be used as an insertion aid for the peridural catheter.
  • the insertion aid designed in this way has a firmer fit on the catheter and is not lost when handling as easily as the previous one, which was completely loose on the catheter.
  • the hole at the catheter outlet is conically shaped for better insertion of the catheter.
  • the clamping piece receptacle can be continuously conical up to the catheter outlet and the support ring can have a step for enclosing the clamping piece and a conical insertion.
  • This configuration means a simpler and cheaper manufacture of the clutch housing.
  • the inner wall of the clutch housing has an acute-angled shoulder in which the clamping piece, which is also formed at an acute angle, lies.
  • the support ring is dispensed with, the function of which is not required for the sealing. This may be desirable if only a single function is desired, and this is sufficient for use with the peridural catheter. In this case, changing the coupling is out of the question in practice, as this would mean removing the bacterial filter.
  • the clamping piece is driven into the conical bore of the coupling by the LUER lock attachment.
  • the present invention is characterized in particular in that it has the advantage over the known pinch rubber seal used in catheter couplings, which is compressed in the longitudinal axis, that significantly lower forces are necessary for the deformation. This enables the use of a coarse thread with only a few threads.
  • threads in the form of standardized LUER lock connections are used in medicine.
  • commercially available LUER lock connection pieces can therefore be used, into which only a suitable clamping piece in the form of an advantageously standardized tube is inserted; however, such a thread cannot be used for a pinch rubber seal.
  • the further DE-OS 31 00 442 shows a valve arrangement for a catheter equipped with a special connection cone (and not freely passing through a clamping piece).
  • DE-AS 27 45 899 deals with the adaptation of two special catheter connectors to one another, but also does not show the pinching of a free-ended catheter in the simple manner taught by the invention.
  • DE-OS 31 00 622 also deals with the opening of a valve disc in a connecting device for connecting catheters, but does not teach the be special type of clamping a free catheter end by means of a conical part already present. The same applies to DE-OS 30 00 903.
  • DE-OS 29 26 352 relates to a connecting device for lines with a locking sleeve for male and female LUER cone parts.
  • a connecting device for lines with a locking sleeve for male and female LUER cone parts there is no special way of pressing in a free catheter end using existing cone parts.
  • DE-OS 29 007 S32 which deals with an additional protective cover for nested cone parts of a connecting device for catheters or the like, but does not show such a clamping piece arrangement as the present invention.
  • US Pat. No. 4,254,773 deals only with a liquid-tight rotary coupling for catheter systems, but the catheter end can be pushed onto a connecting cone in a sealing manner, but is not clamped in by means of a clamp piece.
  • DE-OS 28 26 660 relates to a catheter coupling in which a free-ended catheter is sealed by plugging it onto a mandrel and pressing it in circumferentially by means of a clamping nut.
  • the invention is shown in four imple mentation examples.
  • Figure 1 shows on an enlarged scale a catheter coupling in which, according to the main features of the invention, a male and female LUER connector are connected in a clamping piece with simultaneous clamping of the catheter end.
  • Figure 2 shows a broken-out piece of the coupling with a special design of the housing with a tapered inner bore.
  • Figure 3 shows an embodiment of the invention without a support ring for single use.
  • FIG. 1 shows a catheter coupling with a device attached to the head, such as an injection syringe, infusion syringe or bacterial filter, and a catheter 10 inserted from the bottom (Tapered plug-in attachment) of the device 1, the upper part 9 of the clamping piece 8 being guided in the bore 7 of the LUER attachment 2 and being clamped there.
  • a through hole In the upper part 9 of the clamping piece 8 is a through hole in which the rear end 11 of the catheter 10 is guided.
  • the upper clamping piece end 9 and the catheter end 11 are now compressed airtight via the screw connection elements 5 and 6.
  • This LUER lock connection is a unit standardized in medicine.
  • the clamping piece 8 is conically formed in its upper part 9.
  • the male LUER attachment 2 has an equally conical shape at its lower end. This ensures a trouble-free introduction of the LUER approach via the clamping piece.
  • the clamping piece 8 is firmly pressed or glued with its lower part 13.
  • the support ring 14 is firmly inserted on the inside of the lower part 13 of the clamping piece.
  • the support ring has a bore for the passage of the catheter, which is conical at its lower end 17, so that a safe insertion of the catheter 10 is ensured.
  • the clamping piece 8 is supported in its lower part 13 against the shoulder 16 of the housing 3.
  • the taper formed in the lower part of the bore 19 also serves for the safe insertion of the catheter.
  • the lower end of the coupling housing is designed as a male LUER attachment 18 and can thus also be used as an insertion aid for the peridural catheter.
  • the clamping piece receptacle 20 is designed as a continuous conical bore in the longitudinal axis.
  • the support ring 14 ' abuts the bore and has a shoulder 21 on which the clamping piece 8 is supported in the longitudinal direction.
  • the support ring 14 ' is also conically formed on its underside 22 for the safe insertion of the catheter 10.
  • FIG. 3 shows a section of the clutch housing 3 with a lower inner wall region 15 ', which has an acute-angled shoulder 23.
  • the clamping piece 8 ' which is also conically formed at an acute angle at its lower end, is supported on this.
  • the inner diameter of the clamping piece 8 ' is smaller than the input diameter 19' at the lower end of the clutch housing.
  • FIG. 4 A further simple embodiment of the invention is shown in FIG. 4, in which the introduction of a support ring is also dispensed with.
  • the coupling housing 3 shows a conically tapering bore 15 'adjoining the female LUER approach, in which the clamping piece 8''is inserted.
  • the clamping piece has on its lower part the conical widening 24 through which the catheter 10 is inserted.
  • the catheter in the clamping piece is pressed by axial pressure of the male LUER attachment 2 on its head side, which causes a radially closing deformation of the bore of the clamping piece.
