Device Description
The STERIZONE® VP4 Sterilization chamber has a capacity of 4.4 cu. ft. (125 liters). It requires oxygen (94% pure and greater), electricity and the 125-280 Solution™ containing 50% hydrogen peroxide by weight. Both hydrogen peroxide and ozone are used in a multiphase process. The STERIZONE® VP4 Sterilizer is equipped with a factory-programmed control system offering a unique sterilization cycle. Processed medical instruments are ready to use immediately after the cycle ends; no aeration is required. Polypropylene non-woven wrapping material, non-woven polyethylene (Tyvek™) with polyester/LDPE transparent film pouches, and vaporized hydrogen peroxide compatible aluminium containers using disposable polypropylene filters, are used as packaging for medical devices to be sterilized. Plastic and metal trays are also suitable packaging means when combined with polypropylene wraps. A self-contained biological indicator containing spores of G. stearothermophilus, incorporated into a test pack, is recommended to monitor cycle performance. The STERIZONE® VP4 Sterilizer could be installed as a free standing unit or recessed behind the wall. No exhaust gas ventilation duct is required as long as the room is adequately ventilated.

The document describes a sterilizer intended for medical devices, not a device used for therapy on humans.

No

This device is a sterilizer, meaning it cleans and disinfects medical devices, making them ready for use. It is not used to diagnose a patient's condition or disease.

No

The device is a physical sterilizer that uses hydrogen peroxide and ozone to sterilize medical devices. It is a piece of hardware with a control system, not a software-only device.

Based on the provided text, the STERIZONE® VP4 Sterilizer is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use is "terminal sterilization of cleaned, rinsed, and dried metal and non-metal reusable medical devices in health care facilities." This describes a process for making medical devices sterile for use on or in the human body, not for examining specimens from the human body.
  • Device Description: The description details a sterilization chamber, the sterilization process using hydrogen peroxide and ozone, and compatible packaging materials. This aligns with a sterilization device, not an IVD.
  • Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing human specimens (blood, urine, tissue, etc.)
    • Providing information about a patient's health status, diagnosis, or treatment
    • Using reagents or assays for testing
    • Outputting diagnostic results

The STERIZONE® VP4 Sterilizer is a device used to prepare medical instruments for use, which is a crucial step in healthcare but distinct from the function of an IVD.

N/A

Intended Use / Indications for Use

The STERIZONE® VP4 Sterilizer is intended for use in terminal sterilization of cleaned, rinsed, and dried metal and non-metal reusable medical devices in health care facilities.

The single pre-set cycle of the STERIZONE® VP4 Sterilizer uses hydrogen peroxide and ozone. The injection of vaporized hydrogen peroxide is followed by the injection of ozone, which reacts with residual hydrogen peroxide to form hydroxyl radicals.

Sterilization efficacy was demonstrated using a representative sample of one or more device types and packaging, in seven separate validation loads, as described in Table 1. The load to be processed should be maintained between 20℃ to 26℃ (68°F to 78°F). Total load weight shall not exceed 75 lbs. inclusive of the containers/packaging weight but excluding the 25 lbs loading rack.

Process description

The STERIZONE® VP4 Sterilizer offers a single pre-set sterilization cycle designed for the sterilization of general instruments, single channel flexible endoscopes, rigid and semi-rigid channeled devices including single channel and double channel rigid endoscopes.

The STERIZONE® VP4 Sterilizer uses dual sterilants, vaporized hydrogen peroxide (H202) and ozone (O3), in a multiphase process.

Upon loading the medical devices into the sterilization chamber and closure of the door, the chamber is subjected to a vacuum of 1 Torr (referred to as pre-conditioning step). The first cycle phase (Phase 1) is initiated with the Dynamic H2O2 exposure step. During this step, a 50 weight-percent hydrogen peroxide solution (referred to as 125-280 Solution™) is injected at a fixed injection rate in vapor form into the sterilization chamber through a continuous micropulsed injection until a differential pressure set point of 19 Torr is reached (i.e., the actual chamber pressure is 20 Torr, less the initial vacuum of 1 Torr, which is equivalent to a "differential pressure" or "AP" of 19 Torr). The total amount of hydrogen peroxide introduced into the sterilization chamber and thus the duration of the injection varies depending on load composition (e.g. surface area), weight and temperature.

The second step of the cycle phase is the H2O2 Reduction Step. During this step, a set concentration of ozone is injected into the chamber and reacts with residual hydrogen peroxide to form hydroxyl radicals.

During the second cycle phase (Phase 2), the same sequence is repeated, including the Dynamic H2O2 exposure and H2O2 reduction steps. The full Cycle is then completed with an evacuation and ventilation, through a catalytic converter, to the atmosphere, at which point the chamber door can be safely opened.

The cycle process parameters are summarized in Table 1.

Table 1. STERIZONE® VP4 Sterilizer – Cycle process parameters

  • Vaporized hydrogen peroxide injection/exposure time (Dynamic H2O2 exposure step) varies with load composition and conditions. The quantity of vaporized hydrogen peroxide injected is directly related to the time required to reach a pressure differential of 19 Torr in the chamber, for load temperature ranging from 20℃ to 26℃. If the H2O2 injection time is less than 210 seconds, or greater than 600 seconds, the cycle will abort.

Intended Use

The STERIZONE® VP4 Sterilizer is intended for use in terminal sterilization of cleaned, rinsed, and dried metal and non-metal reusable medical devices in health care facilities.

The single pre-set cycle of the STERIZONE® VP4 Sterilizer uses dual sterilants hydrogen peroxide and ozone. The injection of vaporized hydrogen peroxide is followed by the injection of ozone, which reacts with residual hydrogen peroxide to form hydroxyl radicals.

Sterilization efficacy was demonstrated using a representative sample of one or more device types and packaging, in seven separate validation loads, as described in Table 2. The load to be processed should be maintained between 20°C to 26°C (68°F to 78°F). Total load weight shall not exceed 75 lbs, inclusive of the containers/packaging weight but excluding the 25 lbs loading rack.

Description of Device

The STERIZONE® VP4 Sterilization chamber has a capacity of 4.4 cu. ft. (125 liters). It requires oxygen (94% pure and greater), electricity and the 125-280 Solution™ containing 50% hydrogen peroxide by weight. Both hydrogen peroxide and ozone are used in a multiphase process.

The STERIZONE® VP4 Sterilizer is equipped with a factory-programmed control system offering a unique sterilization cycle.

Processed medical instruments are ready to use immediately after the cycle ends; no aeration is required.

Polypropylene non-woven wrapping material, non-woven polyethylene (Tyvek™) with polyester/LDPE transparent film pouches, and vaporized hydrogen peroxide compatible aluminium containers using disposable polypropylene filters, are used as packaging for medical devices to be sterilized. Plastic and metal trays are also suitable packaging means when combined with polypropylene wraps.

A self-contained biological indicator containing spores of G. stearothermophilus, incorporated into a test pack, is recommended to monitor cycle performance.

9

The STERIZONE® VP4 Sterilizer could be installed as a free standing unit or recessed behind the wall.

No exhaust gas ventilation duct is required as long as the room is adequately ventilated.

Effectiveness

The STERIZONE® VP4 Sterilizer performance validation testing was performed using the « overkill » approach to demonstrate the effectiveness of the process. Testing on directly inoculated medical devices was conducted employing half-cycle to demonstrate achievement of a sterility assurance level (SAL) of 106 at the complete cycle.

This process has been demonstrated to be effective for terminal sterilization of packaged reusable medical devices.

Safety

The STERIZONE® VP4 Sterilizer has been designed, constructed and tested to meet the safety and performance requirements of various North American safety codes and standards. The STERIZONE® VP4 Sterilizer complies with the applicable portions of the following standards:

  • Canadian Standard Association (CSA) Standard C22.2 No 61010-1: 2004 .
  • Underwriters Laboratory Standard UL 61010-1: 2004
  • Federal Communication Commission (FCC) Part 18 / EN 55011 ●

Indications for
Use | The STERIZONE® VP4
Sterilizer is intended for
use in terminal
sterilization of cleaned,
rinsed, and dried metal
and non-metal reusable
medical devices in health
care facilities. | The STERRAD® 100NX®
Sterilizer is designed for
sterilization of both metal
and nonmetal medical
devices at low
temperatures. The
STERRAD sterilization
process is a multiphase
sterilization process that
utilizes a combination of
exposure to hydrogen
peroxide vapor and
plasma to safely sterilize
medical instruments and
materials without leaving
toxic residue. | The Amsco V-PRO maX
Low Temperature
Sterilization System, with
VAPROX® HC Steriant, is
a vaporized hydrogen
peroxide sterilizer
intended for use in the
terminal sterilization of
cleaned, rinsed, and dried
reusable metal and non-
metal medical devices
used in health care
facilities. |
