European Medical Device Nomenclature (EMDN) is the nomenclature of use by manufacturers when registering their medical devices in the EUDAMED database. EMDN is characterised by its alphanumeric structure that is established in a seven-level hierarchical tree.
In Europe, medical material that fulfills the definition of a medical device according to the MDR (Medical Device Regulation) is classified into 4 classes

  • EANEANAE4-- PORTABLE ANAESTHESIA SYSTEM (Diamedica DPA02) + scavenger - PIITM.pdf
  • Portable Anaesthesia System Diamedica DPA02 (Technical Manual)



A portable, stand-alone, mechanical device allowing anesthesia without pressurized gaz for spontaneous or assisted ventilation.

The DPA tank is a thermostabilized and calibrated vaporiser. Its low internal resistance allows ambient air to be used as the carrier gas for volatile agents (draw-over anaesthesia). The DPA tank can also be used with medical gas continuous flow systems, or on anaesthetic respirators.

The DPA02 is used to provide draw-over anesthesia technique. It allows the use of halogene agents (halothane, isoflurane). It can be used with low pressure oxygen source such as oxygen concentrators.

The new DPA02 valve and patient circuit removes the valve from the vicinity of the patient airway and allows the use of standard Y circuit. This valve is more suitable to the spontaneous ventilation than the previous ones.


The configuration chosen my MSF includes

  • 2 adult circuits: EANEANAA411
  • 2 paediatric circuits (children >10 kg): EANEANAA412
  • 2 Jackson Rees modified - T circuit Mapleson F - 0.5 l balloon open tail (T piece system): EANEANAA305

Supplied with the scavenging system EANESCAV1--

Instructions for use

For draw-over inhaling anaesthesia without N2O.

The vaporiser is calibrated either for isoflurane, either for halothane (for the new circuits sent by MSF only Isoflurane is used).

The gaseous mixture must be enriched with oxygen (bottled or from an oxygen concentrator).

Precautions for Use

Halothane and isoflurane must never be mixed.


The use of an antibacterial-antiviral filter is mandatory between each patient.

The patient circuit should be cleaned once a week with water and soap.

The system should be wiped with a detergent-disinfectant solution for surfaces after each procedure.

In case of shortage of filter, the DPA2 valve and the patient circuits should be autoclaved between each patient. At that time, T piece circuit should be considered as single use.

Basic maintenance can be performed by the anaesthetist.

MSF requirements

The DPA is the vaporiser of choice for draw-over anaesthesia in MSF.
