ERS: European Respiratory Medicine Event

The European Respiratory Society (ERS), organized its 29th congress from 28 September to 02 October 2019 in Madrid, Spain. Showcasing the excellence of respiratory medicine, it is an essential event for all pneumology professionals and the patient associations concerned. It brings together more than 15,000 doctors, scientists and other specialists in respiratory medicine (research laboratories, etc.).


This event promotes scientific research and provides access to educational resources on diseases such as asthma, the heart of the Optimhal-Protecsom laboratory.




Promising resultats presented by OptimHal-ProtecSom


The Optimhal-Protecsom laboratory actively participated in this knowledge sharing by presenting its latest research on several inhalation chambers for mechanical ventilation circuits, including Combihaler.


Combihaler® is an inhalation chamber for mechanical ventilation systems. It allows for the simultaneous administration of metered-dose drugs and a mesh nebulizer.

In this study, the in vitro performances of several spacers, including CombiHaler®, were evaluated for drug delivery with pressurized metered dose inhaler (pMDI) and vibrating mesh nebulizer, in comparison with T adapters usually used, in an adult mechanical ventilation model.


Results showed that in vitro drug delivery is higher when using a spacer instead of T pieces, with both a pMDI and a vibrating mesh nebulizer.


CombiHaler has similar or higher in vitro performances than other spacers and permits the use of both a pMDI and a vibrating mesh nebulizer without dismantling the breathing circuit : these are new successful results which strengthen our goals and our purpose of continuous improvement. 


Each year, the Optimhal-Protecsom laboratory invests more than 25% of its turnover in research. This is an essential point for designing tomorrow’s medical devices with a constant goal : to improve the quality of life of patients and facilitate the work of caregivers.

Coughing, runny nose, stinging, itching, it’s red… What if it was an allergy to mites? It’s the high season!

In autumn, all the conditions are met to promote the proliferation of dust mites: heated housing, less airy, closed windows and reduced light are all factors that contribute to the concentration of allergenic particles in your indoor environment.


More than 3 in 10 French people suffer from allergy to dust mites and many people ignore it or minimize its consequences.



So, are you one of those allergic people who ignore themselves ? 

Among the 35% of French people who say they are allergic, 1 in 2 people considers that it is not a “real” disease and is thus exposed to a sometimes very serious evolution of their allergic disease. Asthma has an allergic origin for 80% of children and 50% of adults.

Respiratory illness is not to be taken lightly!

The association Asthme & Allergies calls, through an information and awareness campaign, patients and parents of allergic children to mobilize to better and faster detect allergy to dust mites in order to avoid these evolutions to asthma or other severe pathologies.


The Protecsom Laboratory, a specialist in allergen protection and improvement of the quality of life of patients, actively participates in this new awareness campaign of the association Asthma & Allergies, with several other partners and actors in the fight against mite allergy.

A 100% digital campaign !


This awareness campaign is deployed in the media and on social networks.
Discover four videos that feature the different symptoms of mite allergy (Eternity, Difficult Awakening, Runny Nose, etc.) and a page to answer all questions related to mite allergy. (Symptoms, Solutions and Risks).
A game created by the association Asthma & Allergy may also allow you to gain your protection. Be vigilant !



Emma, ​​apprentice at the Laboratoire OptimHal-ProtecSom has received the regional medal of the contest “Un des Meilleurs Apprentis de France”

Emma Blondel obtained, Sunday, June 2, 2019, the departmental and regional gold medal of the contest “Un des Meilleurs Apprentis de France” in the ready-to-wear category.



This competition, organized by the “Société Nationale des Meilleurs Ouvriers de France”, is intended for young people under 21 years in initial training or apprenticeship contract, represents the excellence of know-how in more than 200 trades.


A prestigious award that recognizes the motivation, investment and work quality of Emma, ​​a young apprentice in the Laboratoire OptimHal-ProtecSom. And it’s not over ! With this victory Emma will extend the pleasure by participating in the national contest.


Back on her story and passion for fashion :


How was born your passion for fashion and couture ?

Emma: “Already a little girl, I had fun customizing the clothes of my Barbies. It really was a trigger and that’s how I showed an interest in the fashion business.”


Then Emma decided to choose a training in connection with her passion: A bachelor’s degree “Métiers de la Mode Vêtement” at the Thomas Pesquet high school in Coutances. She is doing her alternating training in the Laboratoire OptimHal-ProtecSom which has provided this young apprentice an environment conducive to the success of its various projects.

Soon the end of your apprenticeship, do you already know which business of fashion will you lead to ?

Emma: “During my second year of training, I participated in my first competition: Fashion in Normandy. I realized the technical part of a garment, research part before its conception (choice of the tissues, range of assembly…). This first contest allowed me to consolidate my professional project : to work in a design office and method, to be the link between production and offices. “

What were your motivations to participate in the contest “Un des Meilleurs Apprentis de France” ?

Emma: “I was supported and encouraged by my professors and colleagues from the  Laboratoire OptimHal-ProtecSom”.

Tell us how the contest “Un des Meilleurs Apprentis de France” was occured !

Emma : “We had the choice between 3 projects : ready-to-wear, fuzzy clothes or tailor. I preferred the ready-to-wear theme in which we had to make a dress, subject to specials requirements. For 3 months, I designed step by step the dress and its technical file.”

You received the gold medal, what does it mean for you ?

Emma : “This medal is very rewarding for my work. I hope this award will help me in my future career.”

Speaking of future, what do you do after your bachelor’s degree ?

Emma : “After graduating, there are many ways to consider the futur : look for work or go to school. I decided to carry on my studies by integrating a “BTS Métier de la Mode” to get more skills that will allow me to integrate a design office and method.


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