METHOD AND APPARATUS FOR INSERTING AN IV CATHETER |
摘要 |
A method and apparatus for preparing an access site on a patient for insertion of a catheter into one of the patient's veins. The method includes the steps of: providing a tract forming assembly having a leading cutting edge and a dilating body defining a trailing dilating portion, with the cutting edge and dilating body together defining a tract forming unit; advancing the tract forming unit into skin at the access site so that: a) the cutting edge progressively forms a tract through the patient's skin and subcutaneous tissue towards the one vein; and b) the dilating body follows the cutting edge and dilates the tract; and removing the tract forming unit from the dilated tract so that no component resides in the dilated tract to allow a catheter to be directed through the dilated tract and into the one vein.
