Definitions
- Tubular guiding device for introducing a catheter or tube into a vein or other tubular cavity.
- the invention relates to a tubular guiding device to facilitate the introducing of a catheter or tube in a vein or other tubular cavity.
- the guiding device is e- specially advantageous by introducing a tube or cathe ⁇ ter of the kind described in Danish patent No.146 150 into a vein or a tubular cavity.
- problems may ap- pear by the opening of the vein and that the catheter during the introducing through this opening may conti ⁇ nue its movement through the vein in the desired direc ⁇ tion.
- OMPI Guiding devices for the present purpose are known from a.o. Danish patent application 2044/82, which describes various constructions of guiding devices, the outer di ⁇ ameter of which corresponds to the outer diameter of the catheter to be introduced, but which after the in ⁇ troducing may be dilated in a way that the guiding de ⁇ vice after the introducing may be drawn back over the inserted catheter.
- this may be achieved by per ⁇ forming the guiding device as indicated in the charac ⁇ terizing clause of claim 1. Owing to the small diame- ter of the guiding device in its rolled-up condition and its rigidity in longitudinal direction it may be possible directly to insert the guiding device in ure ⁇ thra without causing any pein, and then to introduce a catheter with a considerably greater diameter.
- the guiding device must be made of a thin and elastic material as f.inst. plastic- foil, but in view of its introducing it must have a certain rigidity in longitudinal direction.
- the guiding device may as indicated in claim 2 also be provided with a number, f.inst. 3-6 longitudinally placed thin metal wires preferably hair ⁇ pin-like with its bending at the distal end of the gui-
- OMP ding device to avoid that the distal ends of the wires during insertion will cut into the wall of the vein.
- metal wires will also make it possible to provide the guiding device with a curvature which may be straightened out during the introducing of the devi- ce. Furthermore, this longitudinal reinforcement will have a certain lever-effect which will cause a conical delating of the guiding of a catheter or tube.
- Fig. 1 is a sideview of the guiding device according to the invention
- Fig. 2 a cross section of the line II-II in Fig. 1
- Fig. 3 a cross section of the guiding device in its rolled-up condition
- Fig. 4 a sideview of the distal end of the guiding de ⁇ vice with inserted metal wire
- Fig. 5 the distal end of the cannula in section
- Fig. 6 a cross section of the line VI-VI in Fig. 5.
- Figures 1-4 illustrate an embodiment of a guiding de ⁇ vice according to the invention consisting of a rather thin-walled tube 1, which f.inst. as shown may be a little conical and possibly at its proximal end provi ⁇ ded with an outside bead 5 to facilitate securing the guiding device during insertion of the catheter or tube, and further provided with an adequate number, in the present case four longitudinal strengthening ribs 2 to obtain necessary rigidity of the guiding device in its longitudinal direction to enable it to be inserted in the cannula.
- its cross section must be diminished, which f.inst. may be obtained by rolling-up as shown in Fig.3.
- the catheter or tube When the catheter or tube is inserted through the guiding device, its cross section would be extended as shown in Fig.2.
- the above-named increasing of the rigidity of the guid- ing device in the longitudinal direction may also be obtained by inserting thin metal wires 3 as shown in Fig, 4.
- these metal wires may be hairpin-like with its bending 4 at the distal end of the guiding device.
- a cannula As shown in Fig. 5 and 6.
- its distal end may be temporarily closed by means of a piston-like plug 7 with a reward direc ⁇ ted and through the cannula placed stick 8 to keep the plug 7 on its place during the insertion and following removing of the plug through the cannula.
- the cannula may be opened at its one side by means of a longitudinal slot 9, which make it possible to remove the cannula trans ⁇ versely from the guiding device 1.
- the use of metal wires 3 has the further advantage that the guiding device may be provided with a curvature in order to facilitate its introducing.
- a substantial ad ⁇ vantage of the invention is that the guiding device fa-

Abstract
Un dispositif tubulaire de guidage pour faciliter l'introduction d'un cathéter ou d'un tube dans une veine ou une autre cavité tubulaire est fabriqué à partir d'un matériau mince et flexible, de façon que sa section transversale puisse être réduite pour permettre l'insertion dans une canule, grâce à quoi le dispositif peut être inséré dans une veine et, après retrait de la canule, le dispositif de guidage peut étendre sa section transversale pour guider l'insertion d'un cathéter. Afin de garantir l'insertion et le fonctionnement ultérieur du dispositif de guidage, celui-ci doit être doté de mécanismes assurant une rigidité suffisante sur sa direction longitudinale.
