Intended Use

SafeR® (SafeR Syringe and SafeR Sting) is an automatically Retractable Safety Syringe, it is intended to provide a safe, accurate and reliable method for the aspiration of fluids and for the injection of fluids immediately after filling. It is intended to be used for the administration of medications (intramuscular (IM), intradermal (ID) and subcutaneous (SC)). The syringe, once assembled with its needle, incorporates a passive safety mechanism which retracts and contains the contaminated needle after use, aiding in the prevention of possible infections due to needle stick injuries and syringe re-use. Needle retraction is activated by the syringe user with one hand.

Device Story

SafeR system comprises a piston syringe and a separate needle group (SafeR Sting) assembled via threaded connection; intended for fluid aspiration and IM/ID/SC medication injection. Features passive safety mechanism; user-activated one-handed needle retraction into plunger hollow stem post-injection; prevents needlestick injuries and syringe reuse. Used in hospital or home settings by clinicians or patients. Output is the delivered medication dose; device design ensures standard injection techniques. Benefits include reduced risk of accidental needlestick injuries and prevention of reuse.

Clinical Evidence

Bench testing only. Testing included visual inspection, dimensional verification, pH, corrosion resistance, extractables, lubricant amount, needle point/bonding/penetration, volume/dead space, leakage (air/liquid), piston force, and safety feature activation per ISO 7886-1, ISO 7864, ISO 23908, and ISO 80369. Biocompatibility (ISO 10993), sterilization (ISO 11135), and shelf-life testing confirmed performance and safety. Usability evaluation conducted per EN 62366-1.

Technological Characteristics

Piston syringe with retractable needle. Materials: Polypropylene barrel/plunger/hub, lubricated isoprene stopper, stainless steel needle/spring, medical silicone lubricant. Luer lock connection. Sterile, single-use. Complies with ISO 7886-1 (syringe), ISO 7864 (needle), ISO 23908 (sharps protection), ISO 11135 (EO sterilization), and ISO 10993 (biocompatibility).

Indications for Use

Indicated for aspiration and injection of fluids (IM, ID, SC) in patients requiring medication administration. Contraindicated for use with the SafeR Sting blunt fill needle on the human body.

Regulatory Classification

Identification

A piston syringe is a device intended for medical purposes that consists of a calibrated hollow barrel and a movable plunger. At one end of the barrel there is a male connector (nozzle) for fitting the female connector (hub) of a hypodermic single lumen needle. The device is used to inject fluids into, or withdraw fluids from, the body.

# 5. Device Description

SafeR® (SafeR Syringe and SafeR Sting) is an automatically retractable safety syringe, it is intended to provide a safe, accurate and reliable method for the aspiration of fluids or for the injection of fluids immediately after filling.

SafeR® system is composed by a body syringe (SafeR Syringe) and a needle group (SafeR Sting). SafeR Syringe and SafeR Sting are 2 (two) products, packaged and sold separately, but designed to be coupled for use. Before use, the end user needs to assemble the body syringe and needle group through a clockwise rotation. Body syringe and needle group are connected by means of a threaded connection and conical mating surfaces between Screw Connector and Barrel. Geometry of the threaded connection was designed to ensure appropriate coupling only between SafeR Sting screw connector and SafeR Syringe barrel. Once assembled with its needle (SafeR Sting), incorporates a passive safety mechanism which retracts and contains the contaminated needle into a hollow stem of the plunger after use, aiding in the prevention of possible infections due to needle stick injuries and syringe reuse. Needle retraction is activated by the syringe user with one hand.

Its intended condition is sterile, single use, for hospital or home use.
