CLOSED PERIPHERAL INTRAVENOUS CATHETER WITH SAFETY SYSTEM CPIVCSS

摘要

The invention relates to a system for inserting an intravenous catheter, in particular to a system for inserting a closed intravenous catheter that avoids the exposure of medical personnel to the bodily fluids of the patient during the insertion of the catheter, with a retractable needle cannula in a bellows-type manual mechanism in order to prevent the reuse thereof, accidental puncture events and the safe disposal thereof. Said CPIVCSS has the advantages of: (a) avoiding the exposure of medical personnel to contaminated fluids or blood during the insertion of the catheter in the patient; (b) reducing the possibility of multiple punctures; and (c) having a safety system which is easy to operate. The Closed Peripheral Intravenous Catheter with Safety System is made up of two systems, which are the puncture and safety system, made up of: (2) the puncture cannula, (10) a mounting body, (11) a holding body, (9) a bellows-type flexible tube, (8) a viewing chamber and filter, and (13) filter paper; and the closed peripheral intravenous catheter, made up of: (3) the catheter hub or connector, (1) the catheter tube, (12) the hub seal, (4) the attachment flanges, (5) the flow tube, (6) the flow-closing lock, and (7) the multi-puncture connector.
