Intended Use

The Model EPV is intended to provide sterilization of medical and dental instruments and to sterilize liquids for non-clinical applications.

Device Story

Table-top steam sterilizer; utilizes vacuum pump, water reservoir, heat source, and sealed chamber. Operates via microprocessor-controlled cycles: unwrapped instruments, wrapped instruments, liquids, Bowie-Dick test, and user-definable cycle. Vacuum pump removes air pockets from porous loads/packs to improve steam penetration; provides post-sterilization vacuum drying. Used in clinics/labs by healthcare personnel. Output consists of sterilized instruments/liquids. Benefits include improved sterilization efficiency and drying compared to non-vacuum models.

Clinical Evidence

Bench testing only. Validation performed using half-cycle and total kill endpoint analysis. Testing conducted under in-use, worst-case, and simulated use conditions. Device successfully rendered all recommended loads sterile.

Technological Characteristics

Stainless steel pressure chamber, door, and locking device. Conforms to ASME code for pressure vessels. Microprocessor-controlled. Includes vacuum pump. Complies with UL 544, CSA, TUV, and Japanese safety standards. Software-based cycle control.

Indications for Use

Indicated for sterilization of solid metal instruments, solid metal hinged instruments, and other materials capable of withstanding required sterilization temperatures and pressures. Intended for use in ophthalmic, dental, and medical clinics, first aid rooms, and small laboratories.

Regulatory Classification

Identification

**Contact Name:** Robert R. Basile, V.P.

**Date Prepared:** June 13, 1997

**Common Name:** Pre-Vacuum autoclave, table-top steam sterilizer

**Trade Name:** Tuttnauer Model EPV Pre-vacuum Autoclave

**Classification Name:**

Steam Sterilizer
Class II Device - 21 C.F.R. § 880.6880

**Substantial Equivalence:**

The Tuttnauer Model EPV series Pre-vacuum autoclave is claimed to be substantially equivalent in safety and effectiveness to the Tuttnauer Model E series autoclave that is currently approved and legally marketed under 510(k) number K920478. The Model EPV series is an improvement of the basic E Model through incorporation of a vacuum pump and minor modification of the software driver to narrow the sterilization temperature control range.

**General Description:**

The Tuttnauer Model EPV series autoclave is a table-top steam sterilizer that includes as its main components a vacuum pump, water reservoir, heat source and sealed chamber. As with the predicate device, the EPV has three pre-programmed sterilization cycles, one user definable cycle and a Bowie-Dick test cycle. The three pre-programmed cycles are for unwrapped instruments (134°C at 3 minutes), wrapped instruments (134°C at 7 minutes) and liquids (121°C at 30 minutes).

The Model EPV autoclave is produced in two sizes, the 2340EPV with a chamber size of 9" x 18.5" and the 2540EPV with a chamber size of 10" x 18.7".

## Design and Materials:

The pressure chamber, door and locking device are constructed from stainless steel. The pressure chamber, and components are designed, tested and stamped for conformance to ASME code.

A microprocessor controls the cycle parameters. The software provides the microprocessor with the necessary information to control the device within its desired parameters. The software has been validated to ensure compliance with all applicable requirements.

## Intended Use:

The Model EPV is intended to provide sterilization of medical and dental instruments and to sterilize liquids for non-clinical applications.

## Technology Considerations:

With the exception of the addition of a vacuum pump, the Model EPV series exhibits the same technological characteristics as the Model E, its predicate device. All of the components that may be found in the Model E are present in the Model EPV.

The addition of a pre-vacuum cycle to the sterilization program increases the efficiency of the device through removal of air pockets from packs and porous loads, allowing better steam penetration into the packs. The addition of a vacuum pump also provides better drying of sterilized material at the end of the cycle by creating a vacuum in the chamber to increase evaporation.

The software driver for the EPV has been modified in relation to the code for the Model E to take into account the addition of a pre-sterilization vacuum stage and post-sterilization vacuum drying. The software has also been modified to narrow the chamber temperature control specifications in line with European requirements.

## Safety and Effectiveness:

Evaluations have been completed to validate the safety and effectiveness of these devices. Testing was completed using half-cycle and total kill endpoint analysis. The sterilizers were also tested under in-use, worst-case and simulated use conditions. The EPV rendered all recommended loads sterile on half-cycle and all other testing was completed successfully.

The Tuttnauer Model EPV complies with domestic and international safety standards including Underwriter’s Laboratories UL 544, Canadian Standards Association (CSA) medical device standards, European TUV standards and Japanese safety standards. The pressure chamber complies with ASME standards for pressure vessels and Canadian CRN requirements.

510(k) Number: K962282

Device Name: Tuttnauer Models 2340 and 2540 “EPV” Series Table-top Pre-Vacuum Autoclave

Indications For Use: Tuttnauer electronic controlled pre-vacuum autoclaves are intended to be used for sterilization of solid metal instruments, solid metal hinged instruments and other materials that will withstand temperatures and pressure required for sterilization.

The sterilizers have 5 cycles: unwrapped instruments (134°C at 3 minutes and 29 psi); wrapped instruments (134°C at 7 minutes and 29 psi); liquids (121°C at 30 minutes and 16 psi); Bowie Dick test program (134°C at 3.5 minutes and 29 psi); and a free program with adjustable sterilization times and temperatures. With the exception of the free program, all of these cycles are pre-programmed, requiring no user input. The free program allows the user to select their own sterilization parameters, however, the operations manual warns that sterilization has not been validated for user selected settings, and cautions the user that they must validate sterilization.

These autoclaves are intended for use in ophthalmic, dental and medical clinics, first aid rooms, and small laboratories in conformity with 21 C.F.R. § 880.6880.
