Dundas Co.,Inc. - **Product Code:** [CBN](/submissions/AN/subpart-f%E2%80%94therapeutic-devices/CBN.md) - **Decision Date:** Apr 14, 2008 - **Decision:** SESE - **Submission Type:** Traditional - **Regulation:** 21 CFR 868.5430 - **Device Class:** Class 2 - **Review Panel:** Anesthesiology - **Attributes:** Pediatric ## Indications for Use The Passive Waste Gas Scavenger is intended to be used for the scavenging of waste anesthetic gases from anesthesia machines used during the provision of general anesthesia to adults and children. The Passive Waste Gas Scavenger is designed for use with non-recirculating waste gas disposal systems and is intended for prescription use only. ## Device Story Passive Waste Gas Scavenger connects to anesthesia machine ventilation system via horizontal hose terminal; transfers waste gases to non-recirculating exhaust system using ventilator outlet pressure. Device incorporates pressure relief valves to manage excess positive/negative pressure; prevents pressure exceeding 3.0 cm H2O under normal flow (75 L/min). Positive pressure relief limits inlet pressure to ≤ 9 cm H2O during blockages; negative pressure relief prevents inlet pressure falling below -2.5 mm H2O if exhaust becomes active. Reusable device; no patient contact. Used in clinical settings where general anesthesia is administered. ## Clinical Evidence Bench testing only. Performance testing compared subject device to predicates, confirming similar pressure relief functionality and flow characteristics under normal and fault conditions. ## Technological Characteristics Reusable passive gas scavenging apparatus. Materials include hose terminals (30mm/27mm/19mm). Operates via ventilator-supplied pressure. Incorporates positive and negative pressure relief valves. Complies with ASTM 1343-02 for scavenging systems. No electrical energy source; purely mechanical operation. ## Regulatory Identification A gas-scavenging apparatus is a device intended to collect excess anesthetic, analgesic, or trace gases or vapors from a patient's breathing system, ventilator, or extracorporeal pump-oxygenator, and to conduct these gases out of the area by means of an exhaust system. ## Predicate Devices - Ohio Waste Gas Scavenging Interface ([K842003](/device/K842003.md)) - NAD Scavenging Relief Valve ([K790333](/device/K790333.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The device meets the criteria for an active waste gas scavenger in the event the environment changes during use and negative pressure enters the evacuation system. #### Submitter: G. Dundas Company, Inc. 24301 Roberts Drive Black Diamond, WA 98010 253-631-8008 (phone) 360-886-1350 (fax) # Contact: Mario Sorci #### Date: 2 January, 2008 #### Device Name: Passive Waste Gas Scavenger # Classification Name: Apparatus, Gas Scavenging #### Product Code: CBN #### Regulation Number: 868.5430 ### Predicate Devices: {1}------------------------------------------------ # K842003 Ohio Waste Gas Scavenging Interface Applicant: Ohio Medical Products . . - . . . . . : . . # K790333 NAD Scavenging Relief Valve Applicant: Drager Medical, Inc. . : : {2}------------------------------------------------ #### Device Description: The Passive Waste Gas Scavenger is intended to be used for the scavenging of waste anesthetic gases from anesthesia machines used during the provision of general anesthesia to adults and children. The Passive Waste Gas Scavenger is designed for use with non-recirculating waste gas disposal systems and is intended for prescription use only. This scavenging approach relies on the pressure of the waste gas to transfer the gas from the scavenger to the exhaust system. The scavenger body incorporates one 30mm/27mm/19mm horizontal hose terminal to connect the scavenger to the anesthesia machine. The vertically oriented 30mm/19mm hose terminal is intended to connect the scavenger to the exhaust system. The G. Dundas Passive Scavenger incorporates the same safety systems as predicate devices, providing relief of excess positive pressure and excess negative pressure to the patient through the use of pressure relief valves, in compliance with ASTM 1343-02 -Anesthetic Equipment -- Scavenging Systems for Anesthetic Gases. Although there is no standard for passive waste gas scavenging systems, the G. Dundas Passive Scavenger is designed to fail safe under active waste disposal conditions. The G. Dundas Passive Scavenger and the predicate devices were tested and found to have similar performance. Testing procedures and data can be found in Section 7 of this application. #### 3.a. Regulation CBN, Product Code 868.5430 3.b. Principle of Operation: The 14600 Passive Waste Gas Scavenger is intended to be used for the scavenging of waste anesthetic gases from anesthesia machines used during the provision of general anesthesía. It is designed for use with non-recirculating waste gas disposal systems. This scavenging approach relies on the pressure of the waste gas to transfer the scavenger to the exhaust system. The 14600 is not designed for patient contact and is a reusable device. The inlet port is attached to the ventilation system of the anesthesia machine. During operation, waste gases from the patient are transfer into the scavenger by the outlet pressure supplied by the ventilator. The gases will then travel through the scavenger into a non-recirculating exhaust system. Under normal operating conditions (75 L/min flow through the inlet), the pressure shall not exceed 3.0 cm H2O. The 14600 is designed with fault tolerances to handle changes in conditions of both the ventilator and the exhaust system. If pressure increases due to exit port occlusion or a blockage in the exhaust system, the positive pressure relief valve will open, limiting the inlet pressure to less than or equal to 9 cm H₂O. If conditions allow the exhaust system to become an active take away system, the negative relief valve will open, not allowing the inlet pressure to go below -2.5 mm H2O. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the seal of the Department of Health & Human Services - USA.
