Description

The invention relates to a three-lumen catheter device for infusion and blood sampling with a first catheter concentric with egg is surrounded by a second catheter.

A device of the generic type is can be found in EP-PS 00 00 041. The ge there showed device consists of an axially ver running catheter from a second Ka theter is surrounded concentrically, its proxi end before the first catheter lies. This device is used for dialysis purposes for taking and returning blood sets, basically large amounts of blood removed, from there to the cleaning device and get back to the body. they therefore has two catheters, the zen trale, who is simultaneously leading the punk tion channels, the removal and the external the blood return after cleaning leadership serves. During dialysis are constantly Relatively large amounts of blood drawn from the body. When small quantities are withdrawn as a disadvantage that the blood is high Has level of coagulation ability, so that the transport to an analysis station is additionally impossible.

Proceeding from this, the invention has Creation of a catheter device for the task made with the help of the continuous Withdrawal of small amounts of blood with simultaneous Infusion becomes possible.

This object is achieved according to the invention in a catheter according to the preamble through that the infusion over the first catheter and taking blood via the second catheter takes place, within which another, concentric to the second catheter third catheter is arranged, the proxi males end within the outer second kathe ters ends and the space between this and the first catheter supplying an anticoagulant serving solution.

The third catheter is then used due to the spatial arrangement only to that taking blood to prevent coagulation added to the anticoagulant. It will possible, the drawn blood also over larger Transport distance and analysis feed station.

The withdrawal of even small amounts of blood is there with feasible. At the same time, the first catheter introducing an infusion solution whose strength and concentration correspond according to the value determined in the analysis station is controllable. In the specific case, the value of blood sugar is determined and at the same time ent speaking of the result infusion of insulin can be set. The Vorrich invention tion allows the removal comparatively low  blood quantities, so that none for the patient noteworthy weakenings occur more. Wei It is crucial that the anticoagulant supplied completely from the ENT to whom blood is added and not in the Body can spread, which is a delay of Healing process would result. If the the To Guiding the inner catheter used for infusion ending outside is the blood drawn no solution for infusion added, so that the Mes solution can be made completely unaffected. Another advantage is that the removal of blood from a central vessel can, so that occurs in peripheral withdrawals complications and disorders not to be are afraid.

An embodiment of the invention is in the Drawing shown and is in the following nä described here.

It shows schematically Gehal representation of a section in the axial direction tion by the catheter device according to the invention tung.

A first catheter ( 1 ), which is used to supply the infusion solution, is concentrically surrounded by a second catheter ( 2 ). At its proximal end, the second outer catheter ( 2 ) ends before, ie within the first catheter ( 1 ). The second catheter ( 2 ) is used to remove the blood.

It is decisive for the invention that a third catheter ( 3 ) is arranged within the second catheter ( 2 ), the proximal end of which is on the other side ending within that of the outer end of the second catheter ( 2 ). The space between the third catheter ( 3 ) and the first catheter ( 1 ) serves to supply an anticoagulant solution.

The end of the second catheter ( 2 ) protrudes somewhat beyond the end of the third catheter ( 3 ) and is additionally axially rounded at the end. The two catheters ( 2, 3 ) are connected to each other by a screw mechanism ( 4 ) at their attachments ( 5, 6 ). In order to keep the dead space as small as possible, the front part of the extension ( 6 ) of the third catheter ( 3 ) fills the interior of the rear part of the extension ( 5 ) of the outer, second catheter ( 2 ) almost completely up to a jacket-shaped gap out. The first catheter ( 1 ) is used for infusion and protrudes about 15 cm above the end of the other two catheters ( 2, 3 ) so that the infused solution does not mix with the blood which flows between the second and third catheters is sucked in and discharged.

In order to prevent the first catheter ( 1 ) from slipping out, a stopper ( 7 ) in the form of an annular thickening is provided on it. It is fixed with the help of a union nut ( 8 ) on the set piece ( 6 ) of the catheter ( 3 ).

In order not to let the blood drawn coagulate, an anticoagulant solution z. B. heparin pumped into the space between the catheter ( 1 ) and the third catheter ( 3 ) and - after mixing with the blood at the tip of the third catheter ( 3 ) or within the second catheter ( 2 ) and without in the vascular system of To reach patients - the blood-heparin mixture is sucked in between the second ( 2 ) and the third catheter ( 3 ). The quantitative relationship between heparin and blood is determined by the inner diameter of the supply and discharge of the hose in the area of the feed pump or its setting.

Claims (1)

  1. Triple-lumen catheter apparatus for infusion and blood collection is provide with a first catheter (1) concentrically by a second catheter (2) around, characterized in that via the first Kathe ter (1) the infusion and theter via the second Ka (2 ) the blood is withdrawn, with a further third catheter ( 3 ) located concentrically to the second catheter ( 2 ), the proximal end of which extends inside the outer second catheter ( 2 ) and the space between this and the first catheter ( 1 ) serves to supply an anticoagulant solution.
