[0048] The bottle warming device 100 simplifies the existing designs by using a microwave or previously heated or cooled water instead of building electric heaters into the bottle warmer.

Abstract

L'invention concerne un dispositif de chauffage et de refroidissement de biberon utilisant un liquide chauffé, tel que de l'eau, pour chauffer un liquide dans le biberon. Dans un autre mode de réalisation, le dispositif de chauffage de biberon utilise de l'eau chauffée pour réchauffer du lait dans le biberon. Le dispositif de chauffage de biberon réchauffe le biberon à une vitesse qui n'est pas trop rapide pour dégrader le lait maternel, mais qui est suffisamment rapide pour être commode pour des soignants. Le dispositif est facile à nettoyer et à utiliser de telle sorte que les soignants ont confiance que le biberon chauffé est correctement aseptisé. Le dispositif est également très simple et bon marché du fait qu'aucun élément de chauffage direct n'est intégré dans le dispositif.
