Abstract: Provided is an Extraction Device for Collecting Blood Samples, including a Catheter and a Safety System “EDCBSCSS” wherein a catheter is inserted through a cannula, which retracts once the catheter is inside a vein, by means of a spring and safety latch mechanism, retaining the cannula within a housing. The retracted cannula remains immobile within the housing thus avoiding reutilization of the devise and accidental puncture wounds during its disposal. This EDCBSCSS has the advantages (a) among others of assuring that the cutting element has been disabled; (b) possessing a safety system for medical personal so that after the procedure no accidental puncture wounds occur and (c) being easy to handle. The EDCBSCSS is made up of three sequential operational systems, which are puncturing and retracting system which are located within housings and comprise a puncturing cannula; a catheter; a catheter space, a spring and a safety latch.

Abstract: A peripheral intravenous catheter with bellows-type passive safety system IVCBTS, characterized by including: a retractable puncturing cannula (4) on a manual mechanism of a flexible billows tube (3) in order to prevent its reuse, accidental puncture wounds and assure safe disposal. This IVCBTS has the advantages of: (a) a device which has a passive protection system for preventing accidental puncture wounds, (b) being easily handled. The IVCBTS peripheral intravenous catheter with a passive billows safety system presents two embodiments which are the puncturing and catheterization embodiment and the safety embodiment for the safe disposal of the used puncturing cannula (4). The parts which make up the IVCBTS in its two embodiments are: (1) catheter, (2) affixing body, (3) flexible billows tube, (4) puncturing cannula, (5) mounting body, (6) flashback chamber and filter and (7) filter paper.

Abstract: The present invention refers to a system for placing an intravenous catheter, specifically a closed system for placing an intravenous catheter which prevents exposure by medical personnel to the patient's bodily fluids during the placement of the catheter; and with a retractable needle cannula in a manual billows mechanism for preventing its reuse, accidental puncture wounds and assuring safe disposal. This CPIVCSS has the advantages of (a) preventing medical personnel from being exposed to the contaminated bodily fluids or blood during the placing of the catheter in the patient; (b) reducing the possibility of multiple punctures and; (c) having an easily usable safety system.

Abstract: The invention relates to medical equipment for treatment, specifically medical equipment for extracting and draining fluids contained in the bladder of a patient. The Foley catheter according to the invention comprises tubing, with at least two lumens, made of a biocompatible polymer material with a length of between 100 and 400 mm and outer diameters of between 1 and 15 mm. The surface of the tubing has a high-relief texture with a maximum height of 30 micrometers and patterns designed to generate the property of hydrophobicity and to reduce the adhesion of bacteria to said surface. A collecting funnel with at least two channels, made from medical-grade polymer material, is fixed to the distal end of the tip of the tubing, while the tip of the tubing is closed in such a way that it forms a rounded tip. A flexible inflatable balloon is arranged upstream of the tip, for the anchoring of the catheter.

Abstract: The Extraction Device for Collecting Blood Samples, including a Catheter and a Safety System in which a flexible catheter instead of a metallic cannula with sharp edges for extracting blood is presented. This catheter is inserted through a traditional cannula, which retracts once the catheter is inside the vein, by means of a spring and safety latch mechanism, retaining the cannula within a rigid housing. The retracted cannula remains immobile within the rigid housing thus avoiding reutilization of the devise and accidental puncture wounds during its disposal.

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