OptimHal-ProtecSom laboratory was present at the Respiratory Drug Delivery (RDD) to present three new studies.

OptimHal-ProtecSom laboratory participated to the new edition of the “Respiratory Drug Delivery” Congress holding in Estoril’s Convention Center in Lisbon, Portugal, from May 7th to 10. This congress is one of the most important international event dealing with drug delivery system by respiratory route.

Research team of laboratory OptimHal-ProtecSom was here with a rich and varied program: expositions, sessions, workshop…


OptimHal-ProtecSom emphase on the innovation 

OptimHal-ProtecSom laboratory invests every year more than 25% of its income in its research center. This contribution is essential to offer our team the means to imagine and create medical devices for the future which improves the quality of life to the patients and the work of medical staff.  

Every medical device in our laboratory are subject to various scientific studies to validate their efficiency. This year, three studies had been submitted to the “Respiratory Drug Delivery” congress.

DigitHal®, smart valved holding chamber

Throughout the congress, Edouard CURRAN, PhD, R&D project manager at laboratoire OptimHal-ProtecSom, presented a poster about DigitHal® probe. In this study, an instantaneous, accurate and reproducible measurement of the patient’s respiratory flow was performed by the probe during the valved holding chamber use. The impact of the probe on the drug delivery has also been studied and no change in the efficiency of the valved holding chamber was detected.

With these information, DigitHal® probe could be used as a learning tool which improving technique to the patient.


The importance of developing such help devices was exposed a long time during the session 5 of the congress : “ Re-inventing Inhalers for the Digital Age”.

Doctor (PhD) Myriam ECKES, project manager R&D in OptimHal-ProtecSom laboratory, exposes two posters about mechanical ventilation studies.

CombiHaler®, spacer for mechanical ventilation system

The first one deals with the In Vitro performances of CombiHaler® spacer. Dedicated for mechanical ventilation system, CombiHaler® allows the use, without disassembling of the circuit, of a pMDI and a vibrating mesh nebulizer.

The aim of this study was to evaluate the effect of the volume of CombiHaler® spacer on the administration of drugs by mechanical ventilation.


The results shows that the volume has a strong influence when inhalation chamber is placed before the Y piece and less when it’s placed after.

MinimHal®, the spacer with low volume for mechanical ventilation circuit

MinimHal® is an inhalation chamber with small volume for use in mechanical ventilation breathing system.

Its low volume allows a use for paediatric patients and at different locations on the mechanical ventilation circuit.

The aim of this study was to evaluate the in vitro performance of MinimHal® in a mechanical ventilation circuit.
