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
OC subscriptions: included in supply or field order tools (e.g. UniField)
SC subscriptions: included in supply or field tools
OC validations: approved for procurement and use by an OC for international or local orders specifying context and activity in Medical Standard Lists (MSL)

PEAK FLOW METER, manual

Definition

A manual, hand-held instrument designed to measure only the maximum rate of expiratory gas flow from the lungs. It includes a tube for patient exhalation, easy-to-grip, and a calibrated scale that shows the value of the peak flow.

The device helps to discriminate the pulmonary status in routine tests performed in or outside of a clinical setting; it is also intended for periodic self-evaluation of the respiratory status of a patient, and to help in the treatment evaluation of patients suffering from chronic respiratory disorders (e.g., asthma, emphysema).

Specifications

Quality standards

ISO 23747, 2015, edition 2, (confirmed 2020) Anaesthetic and respiratory equipment - Peak expiratory flow meters for the assessment of pulmonary function in spontaneously breathing humans

Technical specifications

  • Plastic tube or device with pointer
  • European scale (litres/minute) written on the peak flow meter
  • Linear graduation from +/- 60 to 840 l/min
  • Accuracy: ± 10 l/min
  • Dimensions: ± 100 x 60 x 240 mm

Supplied with the Article

  • autoclavable plastic mouthpiece
  • optional: single use cardboard mouthpieces with one-way-valve (to prevent the patient from breathing in any of the previous patient's exhaled breath), box of 100 mouthpieces

Instructions for use

Can be used in children as well as in adults.

  • Insert the mouthpiece into the flow meter
  • Check that the pointer is at zero
  • Stand up if possible
  • Hold the flow meter horizontally so that the fingers do not stop the pointer from moving
  • Take a deep breath
  • Place the mouthpiece into the mouth
  • Blow as hard and fast as possible (blowing a long time doesn't help)
  • Repeat this attempt 2 times and write down the highest reading
  • Dispose of the cardboard mouthpiece after use

Keep a sufficient stock of cardboard mouthpieces (see related articles below)

Maintenance

The plastic mouthpiece can be autoclaved.

The peak flow meter is not autoclavable and must be cleaned and disinfected with a detergent/disinfectant solution for surfaces / non-invasive medical equipment. Prepare use-solution in concentration required. Always read the label and product information before use. Do not mix with other products. Make sure to wet the surfaces completely, use a wipe or towel, keep them wet for the whole exposure time.

Shake well to ensure any trapped air is expelled. Rinse and let dry naturally.
