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.
