Claim:
Peripheral Intravenous Safety Catheter with Quick, Painless Puncture System (PISCQPPS), characterized as comprising: a catheter connected to the catheter holder that is located in the trigger holder that also holds the trigger guard, made up of two halves; the section consisting of the catheter and the catheter-holder is connected, via the said catheter holder, to the catheter-holder tube; the cannula is located inside the catheter, the catheter holder and the catheter-holder tube; at the tip opposite to the free one, the cannula is attached to the cannula holder, while most of the PISCQPPS is located inside the case; between the case and the cannula holder is the bellows, while a spring is located at the distal end of the cannula holder in order to propel it at high speed when the cannula-holder spring is released; before being activated, the halves of catches have been moved along in such a way that the halves of the front and back slits do not match each other and, when the trigger guard has not been activated, the longitudinal ridges of the catheter-holder tube are pressed up against the corresponding areas of the one of the halves of the guard.
