Peripheral intravenous safety catheter with quick, painless puncture system

摘要

We here present the Peripheral Intravenous Safety Catheter with Quick, Painless Puncture System (PISCQPPS) and a cannula with a retractile needle mounted in a manually operated bellows mechanism in order to prevent re-use, avoid accidental perforation and ensure safe disposal. This PISCQPPS offers the advantages of: (a) reducing or eliminating pain; (b) reducing the possibility of multiple perforation; reducing the need for experience and technical know-how in the matter of injection; (c) being fitted with a safety system; and (d) being easy to use. The Peripheral Intravenous Safety Catheter with Quick, Painless Puncture System consists of two sequential operating systems - namely, a painless insertion system that is located inside a case (9), consisting of (1) a catheter, (2) a catheter holder, (3 and 4) a trigger guard, (5) a trigger-guard holder, (6) a catheter-holder tube, (7) a cannula, (8) a cannula holder, (11) a spring, (12) a filter holder, and (13) a filter; along with a safety system inside whose case (9) the cannula holder (8), the cannula (7) and the bellows (10) all operate at the same time.
