Медицинский эжекционный отсос

Medical venturi suction unit

Medical ejection suction unit is used to create a vacuum in the absence of a vacuum in the room. It is possible to use an oxygen lines or compressed air lines for the suction.
Suction can be used in medical consoles of intensive care units, physiotherapy and surgery units. The suction in the infectious departments should be connected through a bacterial filter.

The Venturi AV/500 and AV/1000 vacuum generating system units are particularly suitable in all hospital applications in which it is necessary to get values of vacuum up to -850 mbar and where a central facility of vacuum generation for suction is missing, often for technical choice. As it is well known, the physical principle called “Venturi” allows to get depression from a fluid under pressure, which is obtained, in case of these devices, using medical compressed air coming from the centralized distribution plant. Such devices are composed essentially of a brass chrome-plated body, a needle valve with vacuum adjustment knob and a vacuum gauge. The version AV/1000 fits also a quick I/0 button switch and a large gauge, while in the version AV/500 a protective silicone cover on vacuum gauge avoids damages caused by possible impacts during transport or use

The system release the medical air under pressure into the environment, it is therefore equipped with an effective noise silencer providing a comfortable environment for the patient and the stuff. A special single-pass safety valve has been developed for the system in order to avoid the effect of a return of high pressure on the patient.

The adjusting knob allows you to keep the suction parameters at a same level.
Features: high-speed suction switch I / 0, a powerful silencer for suppressing operational noises.
