Title
(EN) BIODEGRADABLE AIR TUBE AND SPIROMETER EMPLOYING SAME
(FR) TUBE D'AIR BIODEGRADABLE ET SPIROMETRE POURVU DE CE TUBE
Abstract
(EN)
Disclosed is an air tube (12) for use in a spirometer (10). This air tube (12) is disposable and is at least partially, preferably completely, biodegradable, so that it can be economically produced and discarded after use by a single spirometer user. Cross-patient contamination and expensive sterilization procedures are thus avoided. In addition, making this air tube biodegradable allows for the use of plentiful and inexpensive materials of construction, such as cardboard, paper, biodegradable polymers and the like, and reduces the environmental burden caused by disposing of this component.
(FR)
L'invention se rapporte à un tube d'air (12) utilisé dans un spiromètre (10). Ce tube d'air (12) est jetable et au moins partiellement, de préférence complètement biodégradable, de façon qu'il puisse être produit et mis au rebut de manière économique après avoir été utilisé par un seul utilisateur. On évite ainsi de contaminer des patients et d'avoir recours à des procédures de stérilisation onéreuses. De plus, la conception biodégradable de ce tube d'air permet d'utiliser de nombreux matériaux bon marché, tels que du carton, du papier, des polymères biodégradables et similaires, et de réduire l'impact sur l'environnement provoqué par la mise au rebut de ce composant.
