Presentation of an innovative valve holding chamber prototype aiming at cure newborns during the CPLF congress in Paris

 

 

The 24th French Language Pneumology Congress (CPLF) took place in Paris on January 24th. This annual conference allows to more than 5,000 healthcare professionals to discuss the discoveries and innovations in the treatment of allergy and asthma.

 

 

A medical device noticed by the scientific community

Only 30% of newborns are able to inspire enough to open the inspiratory valve of valve holding chambers.1 Moreover, most of valve holding chamber have a dead volume not allowing to children under 1 year of age to inhale efficiently their treatment.2 Facing these facts, the OptimHal-ProtecSom team has developed NeonatHal®, a valve holding chamber without inspiratory valve. This prototype was introduced by Thierry Porée, the Scientific Director of OptimHal-ProtecSom, to the scientific community during a communication selected on abstract by the CPLF Scientific Committee.

 

 

Already promising results

The results are very clear, NeonatHal® use allows to double the delivery of bronchodilators at their action site. These results pave the way toward new studies aiming at determining until what age NeonatHal® offers a clear clinical benefit for the treatment of asthma.

The OptimHal-ProtecSom Laboratory exposes its work during DDL 2019 (Drug Delivery To The Lungs)

 

The Aerosol Society organized its 30th DDL congress in Edinburgh from December 11 to 13.

It is a must-attend annual forum for scientists, academics, clinicians, regulatory and industry experts involved in the development of inhalation medication. On the program, five thematic sessions each with a combination of conferences by experts in the field of inhalation and by students working to advance respiratory science.

 

During this congress, Thierry Porée, scientific director of the OptimHal-ProtecSom Laboratory, presented at a conference our latest work on the inhalation chamber for CombiHaler® mechanical ventilation circuits. An innovation !

 

 

CombiHaler® is an inhalation chamber for mechanical ventilation. It enables the simultaneous administration of medication by a metered dose inhaler and a vibrating mesh nebulizer.

It is intended to be used in hospitals, intensive care, or home hospitalization.

 

 

Research and results of interest have been presented by the OptimHal-ProtecSom laboratory.

Heating and humidifying a mechanical ventilation circuit is needed to protect the lungs of patients under invasive respiratory assistance. However, heat and humidity reduce the dose of aerosols delivered to the patient. We assessed the impact of heat and humidity on in vitro drugs delivery using pressurized metered dose inhaler and vibrating mesh nebulizer with CombiHaler®

This work has demonstrated the advantage of using an inhalation chamber both with a vibrating mesh nebulizer and with a metered dose inhaler, in comparison with the usually used T-pieces.

It also demonstrated that switching off the heated humidifier located in a mechanical ventilation circuit during drug administration did not increase the delivered dose and that the position of the inhalation chamber in the heated and humidified mechanical ventilation circuit had an important influence on this delivered dose.

 

 

Découvrir l’étude

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 !
