<p>An automatic device to confirm the puncturing of the central vein, with a mechanism for the fast initial introduction of the catheter and catheter anchoring device, with three improvements to be pointed out: 1) it has a bellowed balloon which creates a negative pressure, sucking the blood upon the puncturing of the central vein, automatically confirming the said puncturing. 2) It has an automatic trigger which allows the fast and initial introduction of the catheter, avoiding the outflow of the blood. In case some blood flows out, it is kept within the plastic balloon. For that reason, it does not contaminate the manipulator. 3) The quick anchoring hook is safe and eliminates the suture stitches which are normally done in patient, when using the existing models.</p> |
