Description

The GE Tec 7 Vaporizer comes as part of Datex-Ohmeda's reliable line of anesthesia products. It is ergonomically designed and easy to use. Combining clinical performance and the reliability of GE Healthcare's technology, this vaporizer delivers anesthetic agent efficiently to help reduce costs.

Warranty: 3 Years.

The Tec 7 Vaporizer is designed for use in continuous flow techniques of inhalation anesthesia. Each vaporizer is agent-specific and is clearly labeled with the anesthetic agent that it is designed for.

The vaporizer is temperature, flow, and pressure compensated so that its output remains relatively constant despite cooling due to evaporation, variations in inlet flow, and fluctuating pressures.

The Tec 7 is designed to be used on Selectatec Series Mounted Manifolds. The vaporizer can be installed on other Selectatec Manifolds but the interlock system is designed to function on Selectatec Series Mounted Manifolds only. Mounting a Tec 7 Vaporizer on a Selectatec 7 Compatibility Block is not recommended.

Features

GE Tec 7 Vaporizer Features

  • Provides output consistent with the dial setting throughout the clinical flow range.
  • Easy-to-turn dial to help control agent delivery.
  • Two Filling Options: Easy-fil or Quik-Fil (Sevoflurane only).
    • Simplifies agent filling and helps minimize agent leaks while filling.
  • Clinical Performance:
    • Designed to provide consistent output throughout the clinical flow range from 200 mL/min to 15 L/min.
    • Equipped with a large diameter control dial, which incorporates fine graduations of 0.2% between 0 and 1%, and 0.5% from 1% to 8%.
      • The dial for Sevoflurane is marked in steps of 0.2% up to 1% v/v, and in steps of 1% between 1% and 8%.
    • Easy-turning dials and small graduations on the Tec 7 Vaporizer help you fine tune anesthetic delivery over the range of dial settings and flow rates.
    • The Tec 7 Vaporizer can be mounted on GE Healthcare anesthesia delivery systems equipped with the Selectatec manifold without tools and without taking the anesthesia system out of service.
    • An innovative non-spill system limits movement of liquid agent if the vaporizer is tilted or inverted, helping to protect internal components.

Frequently asked questions

Does the Tec 7 Vaporizer ensure consistent delivery?

Yes, the GE Tec 7 Vaporizer is specifically engineered to ensure highly reliable and consistent anesthetic agent delivery across its operational range. This consistency is guaranteed by its advanced compensation features:

  • Comprehensive Compensation: The unit is robustly temperature, flow, and pressure compensated. This critical design prevents changes in the delivered agent concentration caused by factors like evaporation cooling, changes in inlet flow, or pressure fluctuations.
  • Wide Flow Range: It maintains output consistency across the entire clinical flow range, spanning from 200 mL/min up to 15 L/min.
  • Precision Dosing: The large control dial allows for precise tuning, featuring fine graduations (e.g., 0.2% steps between 0% and 1%) for high accuracy in agent delivery.
Does this vaporizer mount easily?

Yes, the GE Tec 7 Vaporizer is designed for tool-free mounting on compatible anesthesia delivery systems. It is specifically intended for integration onto Selectatec Series Mounted Manifolds on GE Healthcare systems.

A key benefit of this design is that the unit can be installed without the need to take the entire anesthesia system out of service.

Is the Tec 7 Vaporizer agent-specific?

Yes, the GE Tec 7 Vaporizer is agent-specific. This critical safety feature ensures precise and reliable anesthetic delivery by engineering each unit to be compatible with only one agent. The available compatibility options are:

  • Isoflurane (Iso)
  • Sevoflurane (Sevo)

The vaporizer also features agent-specific filling options:

  • Easy-fil: The standard filling mechanism available for both Isoflurane and Sevoflurane models.
  • Quik-Fil: An exclusive, simplified filling option available only for the Sevoflurane variant, which helps to prevent spills and minimize leaks.
Is the Tec 7 Vaporizer highly accurate?

Yes, the GE Tec 7 Vaporizer is engineered for highly precise and consistent anesthetic agent delivery across the clinical flow range of 200 mL/min to 15 L/min. This performance is a top selling point.

This reliability is achieved through robust compensation mechanisms:

  • Precision Compensation: The unit is temperature, flow, and pressure compensated. This ensures the output concentration remains stable despite environmental changes (like cooling due to evaporation) or fluctuating flow rates.
  • Intuitive Control: The easy-to-turn control dial features fine graduations (e.g., 0.2% increments) for precise tuning of the anesthetic concentration delivery.

The specific accuracy tolerances (measured at 5 liters/min O₂ at 21 ± 2 °C) are detailed below:

Vaporizer Type Accuracy Tolerance
5% Vaporizer ± 0.25% of delivered agent or ± 15% of dial setting (whichever is greater)
8% Vaporizer (e.g., Sevoflurane) ± 0.4% of delivered agent or ± 15% of dial setting (whichever is greater)
What is the nominal liquid capacity of this vaporizer?

The nominal liquid capacity of the Certified Refurbished GE Tec 7 Vaporizer varies based on the filling requirement and the specific agent configuration (5% vs. 8%).

Key Capacity Specifications

Capacity Measurement Volume Notes
Total Capacity (Dry Wicks) 300 ml Volume needed to fully charge a completely dry unit.
Retained by Wick System 75 ml Volume of agent held within the internal wick system.

The volume required to fill the unit within the standard operating range (minimum to maximum mark) depends on the vaporizer type:

  • 5% Vaporizer (e.g., Isoflurane): 170 ml
  • 8% Vaporizer (e.g., Sevoflurane): 137 ml

What secure anesthetic agent filling options are available?

Yes, the GE Tec 7 Vaporizer utilizes robust, agent-specific filling systems designed for enhanced safety and simplified replenishment. This helps ensure precise and efficient handling of anesthetic agents during use.

Key filling options include:

  • Easy-fil: Supported for both the Isoflurane and Sevoflurane variants.
  • Quik-Fil: This option is available exclusively for the Sevoflurane variant, designed to provide a fast and secure method for refilling the agent.
Does the vaporizer maintain consistent flow output?

Yes, the GE Tec 7 Vaporizer is specifically engineered to ensure highly consistent output regardless of operational fluctuations, which is crucial for inhalation anesthesia. Its compensation system stabilizes agent delivery by being:

  • Temperature compensated
  • Flow compensated
  • Pressure compensated

This ensures the agent output remains consistent with the dial setting across the broad clinical flow range of 200 mL/min to 15 L/min, despite variations in cooling or inflow rates.
