# 4. DEVICE DESCRIPTION

The T-Edge 10 & T-Edge 11 are Table-Top steam sterilizers (autoclave) that use steam as the sterilizing agent. The autoclaves are fully automated device with a computerized control system, which is based on Linux Operating system. that ensures a fully automatic sterilization cycle, control and monitoring of physical parameters and a clear documentation of the sterilization cycle, including the ability of recording the sterilization parameters (with a built-in memory to store history of up-to 999 cycles). A graphical touchscreen is used for monitoring and control purposes.

The T-Edge 10 & T-Edge 11 are Class-B and Class-S devices. They are designed for repeated use of sterilization of medical and surgical goods such as wrapped and unwrapped solid, hollow, and porous loads used in health care facilities.

The T-Edge 10 & T-Edge 11 are validated for use in:

- Sterilizing fabric packs / textiles
- . Sterilizing dental handpieces

The steam for the sterilization process is produced by warming up a controlled amount of demineralized water that is inserted into a pipe heating element and then flows into the chamber as steam. This technique is used as a way of reducing water consumption and saving energy. The autoclave is equipped with a heating element wrapped around the chamber to maintain the required temperatures and steam for the sterilization process. All of these processes are done via the computerized control system of the device.

The T-Edge 10 & T-Edge 11 autoclaves are equipped with a built-in vacuum pump used for fractionated pre-vacuum air removal at the first stage of the cycle, eliminating air pockets from all load types, including porous load and most kinds of tubes (rubber, plastic etc.). This is maximizing efficient steam penetration throughout the entire load, resulting in temperature uniformity and an effective sterilization. After the sterilization stage the vacuum pump is used for post-vacuum drying, performed with the door closed.

The door's locking mechanism is designed to allow closing/opening the door, easily, with one hand.

The chamber door has the following features protecting personnel from hazards:

- . Two door micro-switches that indicate that the door is closed and locked. Without this indication steam is not introduced into the chamber. These micro-switches prevent opening the door while the chamber is pressurized and at the end of cycle until chamber pressure equalizes to room pressure.
- An electrical door locking pin that blocks door opening during operation. .

In addition, the following safety devices are installed in the autoclave to optimize its safe operation:

- A safety thermostat to prevent over-heating of the chamber heating elements. .
- . A safety cut-off switch to prevent over heating of the pipe heating element.
- . A pressure safety valve to prevent over-pressurizing of the chamber.

The T-Edge 10 & T-Edge 11 autoclaves have two optional configurations (available upon request) - a manually filled reservoir of demineralized water or an automatic / direct inlet of demineralized water from the water supply system. The demineralized water overflow outlet is located on the rear cover, demineralized water overflow, and wastewater outlet on the rear cover. Built-in system for checking water quality Automatic water quality checking will alert the user of poor water quality, protecting the autoclave chamber from corrosive minerals found in poor quality water.

The T-Edge 10 & T-Edge 11 feature a built-in memory to record up to 999 sterilization cycles. The T-Edge 10 & T-Edge 11 have a built-in USB port to enable exporting this data to a USB device, to be transferred to a PC.

The built-in USB port also enables the operation of an external, optional barcode printer, by using a dedicated cable - the barcode printer can print labels with a unique cycle ID barcode, operator's name, sterilization and expiry dates. One barcode printer can be connected to the machine. The device also has a built-in network port (LAN) for use with optional Tuttnauer's R.PC.R software.

The chamber is made of a corrosion-resistant 316L stainless steel, and the door is made of corrosion-resistant 304L stainless steel. The outer covers are made of polycarbonate.

### Reason for the 510(k):

The T-Edge 10 & T-Edge 11 are class II device, equivalent to the predicate cleared devices, Elara11 (K143311) and EZ11plus (K111736) but changes made exceeds the limitations for a special 510(k) and thus the device requires a traditional 510(k):

- . The Operating system of T-Edge devices is based on Linux (using Java as the programing language) compared to Windows (using C# as the programing language) in the predicate devices.
- The sterilization time for the Unwrapped delicate cycle in the T-Edge 10 & T-Edge 11 is 10 ● minutes shorter than its equivalent in the EZ11 (20 minutes as compared to 30 minutes).
- The chamber volume of the T-Edge 10 corresponds to the 10" chamber. It differs in 23L . compared to 28.5L. The chamber volume of the T-Edge 11 corresponds to the 11" chamber. It differs slightly in 27.2L compared to 28.5L.
