Definitions
- the present invention refers to a device for introducing a catheter into a blood-vessel and comprising a needle for puncturing the blood-vessel and an introducer-cannula intended to be introduced into the blood-vessel together with the needle and through which the catheter-cannula is intended to 0 be introduced into the blood-vessel after removal of the needle, said introducer-cannula having a front end with a reduced or tapering outer, diameter and which tightly connects to the needle.
- the catheter-over- needle technique
- the catheter is passed on the outside of the needle and this method is used for central venous 5 catheters.
- This method however involves a great risk for • ' .. injuries on the catheterized and neighbouring organs owing to the long needle (16-18 cm.), which besides make the device difficult to handle.
- the catheter is passed through the needle, " catheter-through-steel-needle” technique, at which the needle either may remain or be removed after the introduction of the catheter. Also this methods involves a great risk for injuries and a risk for catheter embolism, by the fact that the catheter easily is damaged by the sharp needle tip.
- a stiff wire is used which is introduced into the blood-vessel
- Desilet's and Hoffmanns technique there is provided a dilatation of the puncture hole by means of a special 0 introducer-cannula, through which the catheter then is introduced. It is however also a complicated method.
- the catheter is introduced into the blood-vessel through the introducer-cannula after the removal of the 0 needle, after which the introducer-cannula is removed from the blood-vessel by displacing it backwards along the catheter.
- the diameter of the catheter is limited by the inside diameter of the introducer-cannula, which is substantially constant except at a rear enlarged section.
- the introduction of the 5 catheter which has substantially the same outer diameter as the inside diameter of the introducer- cannula will be difficult because of the friction against the inner walls of the introducer-cannula along the substantial length thereof. Besides the removal of the introducer-cannula from the blood-vessel can cause problems if the outer diameter of the catheter is not considerably smaller than the inside diameter of the introducer-cannula.
- the device comprises a sleeve, the
- the purpose of the present invention is to provide an 20 introducer-cannula adapted for the introduction of short catheters into peripheral blood-vessels as well as long central venous catheters and which shall fulfil the following demands :
- Fig. 1 is a longitudinal section through an introducer-cannula according to the invention.
- Fig. 2 is a longitudinal section of the whole device including the needle
- Fig 3 is a longitudinal section according to f g. 2 of another embodiment .
- Fig. 4a-c show schematically in a view from above different steps of the introduction of a catheter through an introducer-cannula according to the invention
- Fig. 5-8 show in perspective the front end of different embodiments of the introducer-cannula according to the invention.
- the introducer-cannula 10 is manufactured by a stiff plastic material, for example Teflon(R) and has a reduced front end. Alternatively the whole introducer-cannula 10 tapers towards the front end as is shown in fig. 3,6 and 7.
- the opposite end of the introducer-cannula 10 is shaped as a holder member 11 and is provided with a grip 12 for facilitating the insertion.
- a needle 13 is intended to be received within the introducer- cannula as is shown i fig. 2.
- the reduced front end of the introducer-cannula 10 connects tightly to the needle 13 for facilitating the insertion.
- the needle is provided with a holder member 14 with a grip 15. It would also be possible, as is shown in fig. 3, to give the needle 13 a shape corresponding to the introducer-cannula 10, i.e. a reduced front end or alternatively tapering over its entire length.
- the front tip of the introducer-cannula is provided with a slit 16, which either as is shown in fig. 4 extends all the way to said end or as is shown in fig. 1-4 and 6-7 respectively ends shortly before the end.
- the embodiment shown in fig. 6 is provided with two slits 16 on opposite sides of the introducer-cannula 10.
- a line of weakness 17 connects to the slit 16, for example a groove, perforation or the like, which extends along the entire introducer-cannula 10 including its holder member 11 and along which the introducer-cannula can be splitted at its withdrawal.
- the introducer-cannula 10 has no slit and is instead provided with a line of weakness 17 extending over its entire length.
- the device is used in the following way.
- the blood-vessel either a peripheral or central vein or artery, is punctured by means of the tip of the needle 13 and the whole device comprising needle 13 and introducer-cannula 10 is inserted together into the blood-vessel to the desired position.
- the needle 13 is withdrawn.
- the catheter 18 is then introduced through the introducer-cannula 10, at which the tip of the catheter forces the front end of the introducer-cannula
- the introducer-cannula is easily removed from the catheter by severing it along the line of weakness 17.

Abstract
Une canule d'introduction (10) permettant d'introduire un cathéter dans un vaisseau sanguin est pourvue d'une aiguille (10) sur l'extérieur et est introduite avec cette dernière dans le vaisseau sanguin. La canule d'introduction possède une extrémité antérieure ayant un diamètre conique ou réduit, cette extrémité antérieure étant reliée de manière étanche à l'aiguille. L'extrémité antérieure est pourvue d'une partie expansible, par exemple une partie à fente (16) qui peut être sectionnée par la pointe d'un cathéter (18) ayant un diamètre supérieur à celui de l'extrémité antérieur, pour permettre le passage du cathéter au travers de la canule d'introduction (10) dans le vaisseau sanguin après extraction de l'aiguille (13). En relation à cette partie expansible (16), il est prévu de préférence une ligne d'affaiblissement (17) s'étendant sur la partie restante de la longueur de la canule d'introduction et le long de laquelle la canule d'introduction peut être sectionnée pour facilier son extraction du cathéter (18) lorsque celui-ci a été positionné dans le vaisseau sanguin.
