Abstract

Membranes à couche simple ou à plusieurs couches, telles que des gants et des préservatifs, qui comportent une ou plusieurs couches barrière de désactivation et/ou indicatrices pour indiquer à l'utilisateur la rupture de la membrane ou la présence d'une substance nuisible dans le sang ou dans des fluides corporels. Une membrane peut comprendre une ou plusieurs couches perméables ou semi-perméables destinées à disperser des substances telles que des lubrifiants, des biocides, des spermicides ou des indicateurs vers l'extérieur, et peut également comprendre des couches perméables ou semi-perméables permettant la transmission de fluides corporels ou d'autres fluides ambiants vers l'intérieur de manière à les amener au contact d'une substance indicatrice ou de traitement. Une couche intermédiaire d'une membrane à couches multiples peut comporter une substance destinée à essuyer, nettoyer, stériliser ou traiter d'une quelconque manière une aiguille hypodermique. Une membrane peut comporter un compartiment étanche ou revêtement destiné à piéger des indicateurs ou d'autres agents, tels que des biocides. Un procédé de fabrication de membranes, telles que des gants, permet d'obtenir des gants doubles possédant des couches interne et externe séparées jointes seulement au niveau du poignet. L'ajout de violet de gentiane au latex avant la formation des membranes permet d'obtenir des propriétés biocides, des effets anti-vieillissement prolongeant la durée de stockage et améliorant la résistance à la déchirure, et la réduction des réactions allergiques chez les utilisateurs allergiques au latex.
