Intended Use

The Inviro Snap Safety Syringe is used to inject fluids into, or withdraw fluids from, the body. In addition, the Inviro Snap Safety Syringe is designed to aid in the prevention of needle stick injuries.

Device Story

Inviro Snap Safety Syringe is a retractable needle piston syringe designed to prevent needlestick injuries. After fluid injection or withdrawal, user rotates plunger 180 degrees to couple adapter to plunger; subsequent withdrawal pulls needle into barrel. Lateral pressure on plunger then snaps it off for disposal in sharps container. Device is sterile, gamma-irradiated, and supplied in blister packs. Used by healthcare professionals for standard fluid delivery/aspiration tasks. Benefits include reduced risk of accidental needlestick during post-use handling.

Clinical Evidence

No clinical data. Evidence consists of bench testing including biocompatibility (cytotoxicity, sensitization, hemolysis, systemic toxicity, pyrogenicity), scale accuracy, and mechanical verification (assembly/disassembly forces, cannula bending, leakage tests per ISO 7886-1:1993 and ISO 7864:1993).

Technological Characteristics

Piston syringe with retractable needle mechanism. Materials verified per ISO 10993-1:1997. Sterilized via gamma irradiation. Mechanical operation involves plunger rotation and snap-off feature. Tested for leakage per ISO 7886-1:1993 and cannula separation force per ISO 7864:1993.

Indications for Use

Indicated for injection of fluids into or withdrawal of fluids from the body, while providing a safety feature to aid in the prevention of needle stick injuries.

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.

:

The Inviro Snap Safety Syringe is a retractable type anti-needlestick syringe. The Inviro Snap Safety Syringe is sterilized by gamma irradiation and supplied sterile in blister pack. One hundred blister packs are packaged in a chipboard box. Each Blister pack and chipboard box is labeled with the contents and the appropriate information per the FDA's Quality System Regulation and Labeling requirements.

{1}------------------------------------------------

After use, with the plunger fully compressed, a 180 degree rotation of the plunger couples the Adapter to the end of the plunger. After this coupling occurs withdrawal of the plunger causes the Adapter and the attached needle to be withdrawn into the safety of the barrel. In this position against the flange, lateral pressure on the plunger results in a controlled fracture of the plunger. Both the syringe and plunger are discarded in a Sharps container.

- ய Intended Use:
The Inviro Snap Safety Syringe is used to inject fluids into, or withdraw fluids from, the body. In addition, the Inviro Snap Safety Syringe is designed to aid in the prevention of needle stick injuries.

- Comparison of Required Technological Characteristics: に.
Information was submitted to demonstrate that there are no significant differences in technological characteristics between the Inviro Snap Safety Syringe and the cited predicate device.

- Summary and Conclusion of Nonclinical and Clinical Tests: G.
Prior to testing, First Article Inspections were conducted on all components. In addition, material verification was performed on all components.

The Inviro Snap Safety Syringe assembly was tested per the requirements of the ISO-FDA Modified Matrix, FDA/ODE General Program Memorandum - # G95-1 and ANSI/AAMI/ISO 10993-1:1997 for a External communicating device, Blood path, indirect for a period less than 30 days.

Biocompatibility testing included Cytotoxicity, Intracutaneous Reactivity, Maximization Sensitization Study, In Vitro Hemolysis Study, USP and ISO Systemic Toxicity Studies and USP Prorogen Study. The Inviro Snap Safety Syringe met all of the biocompatibility requirements.

Tests were conducted to determine the accuracy of the scale on the Inviro Snap Safety Syringe. These tests consisted of weighing the syringe, filling the syringe to various increments, weighing the syringe, expelling the fluid and weighing the syringe once again. All weights were recorded. The mean and standard deviation was calculated for all increments. The scale met all accuracy requirements.

{2}------------------------------------------------

Verification Testing consisted of component and interface testing and finished assembly testing. The following tests were performed to verify the compatibility between the interfacing safety syringe components:

- 1. Force to assemble cap In this test, the average force along with the standard deviation is determined to assemble and disassemble the Cap from the Barrel. A good seal between the cap and barrel will reduce the chance that the cap will fall off and expose the needle.
- 2. Force to separate Adapter from Cannula This test was conducted per ISO 7864:1993(E) paragraph 13.1. The average force along with the standard deviation was determined for separating the cannula from the adapter. The ISO Standard requires a minimum of 4,9 lbs of force to separate the cannula from the adaptor.
- 3. Force to Snap off Plunger A torque gauge is used to snap off the plunger from the syringe. This test will verify that the plunger is not too difficult to snap off.
- 4. Cannula Bending Test To verify the cannula can withstand the forces required to penetrate a medicine bottle septum.
- 5. Force required to press out Adapter from Barrel This test determines the force required to push/press out the adaptor from the barrel. This test will assure that the adaptor is not pushed out during an injection.

To verify that the assembled devices met the design requirements, the following tests were performed:

- Freedom from air and liguid leakage past seals Medication leakage can 1. occur around the plunger seal or around the needle holder. This test involves blocking the needle lumen and forcing the plunger handle
- forward. Pressure is increased incrementally and held for several seconds at each increment. The pressure at which leakage occurs and the location of the leak is recorded.
- 2. Pressure Leakage Test - This test was conducted per ISO 7886-1:1993(E) Annex D. In this test series, the system was submerged in liquid and an internal pressure of 43.5 and 400 PSI was applied. Any leakage past the seals was recorded.
- 3. Plunger Action Force - This test was conducted per ISO 7886-1:1993(E) Annex G. This test measures the force to initiate plunger action as well as the maximum and minimum forces required to move the plunger within the Barrel. :

The intended use of the Inviro Snap Safety Syringe is identical to that of the cited predicate device. Verification testing showed that any differences in technological characteristics were insignificant and do not raise new issues of safety or effectiveness.

{3}------------------------------------------------

Conclusion:

.

The Inviro Snap Safety Syringe is substantially equivalent to the Inviro 6 cc Syringe in indications for use and technological characteristics.
