Abstract

A device and a method for facilitating subcutaneous introduction of a plastic carrier includes an element having a supporting portion arranged to be supported on a skin of a patient, and a guiding portion extending substantially transversely to the supporting portion and having at least one slot formed so that when the supporting portion is placed on the skin of a patient and oriented on a surface projection line of an artery and a catheter is introduced through the slot of the guiding portion the catheter is guided on an edge formed in the guiding portion by the slot so that a tip of the catheter is introduced exactly into the artery.

Claims

1. A device for facilitating subcutaneous introduction of a catheter in a peripheral artery, comprising an element having a supporting portion arranged to be supported on a skin of a patient, and a guiding portion connected with said supporting portion and extending substantially transversely to said supporting portion and having at least one slot formed so that when said supporting portion is placed on the skin of the patient and oriented on a surface projecting line of an artery and a catheter is introduced through said slot of said guiding portion the catheter is guided on an edge formed in said guiding portion by said slot so that a tip of the catheter is introduced exactly into the artery, said slot having two ends each provided with an orifice having a diameter which is greater than a width of said slot, and one of said orifices being open outwardly at an edge of said element so as to facilitate easy introduction of a catheter and location of said surface projection line of the artery on the skin.
