Halton Vita Extract is a gas and smoke extraction solution for medical use. It enables the extraction of anaesthetic gases and surgical smoke.
Halton Vita Extract provides a healthier working environment by removing hazardous gases directly from the source. Anaesthetic gases exhaled by the patient can be collected and extracted with the help of a double mask. Surgical smoke can be collected straight from the diathermy device or from the vicinity of the surgical area where the smoke is generated.
The vacuum is generated by one or multiple blower fans of the central unit that is typically located in a ventilation machine room. Vacuum piping is routed throughout the building to individually controlled suction inlets.
The Halton delivery includes all functional system components (central units, suction inlets, control panels, and control valves) as well as design support and the start-up (commissioning) of the system.
Note: The pipework is not included in the delivery.
Fig.1. Halton Vita Extract system
The system can have multiple suction inlets that are connected to the trunk pipework. The medical equipment (patient masks or diathermy devices) can be connected to the suction inlets. The vacuum blowers in the central unit generate a constant vacuum pressure in the pipework. The vacuum extracts the gases out of the medical equipment and forces them out through the exhaust piping. The vacuum airflow for each suction inlet can be adjusted with the control valves that can be operated manually or with an actuator. Dedicated sound attenuators suppress pipe noises for the user’s comfort.
In central unit model ‘secure’, the unit’s blowers and other critical components are duplicated to ensure the system continues running during maintenance or in case there is a component failure. A built-in surveillance function automatically starts using a secondary component if a primary component in the system fails. For maintenance, the blowers and motor drives can be separately disconnected from the power supply. The connecting piping between the two blowers includes one-way valves to prevent vacuum leak through the other blower during maintenance.
