Abstract

La présente invention comprend un instrument de traitement des hémorroïdes comprenant un boîtier (1), une partie en saillie (2) communiquant avec le boîtier (1), une poche de stockage de médicament (4) isolant un premier composant réfrigérant et une enveloppe étanche (3) en liaison étanche avec le boîtier. La partie en saillie (2) peut être introduite dans le rectum d'un être humain. La poche de stockage de médicament (4) qui peut être facilement déchirée est placée dans une cavité formée par le boîtier (1) et l'enveloppe étanche (3) à proximité de ladite enveloppe étanche (3) et un second composant réfrigérant capable de provoquer une réaction endothermique avec le premier composant réfrigérant est placé dans la cavité intérieure du boîtier (1). Le premier composant réfrigérant est isolé par la poche de stockage de médicament (4) du second composant réfrigérant présent dans le boîtier (1), l'enveloppe étanche (3) est située à l'extérieur de la poche de stockage de médicament (4) et il est possible d'expulser la poche de stockage de médicament (4) rompue sous l'effet de l'expulsion de l'enveloppe étanche de façon à ce que le premier composant réfrigérant soit mélangé au second composant réfrigérant pour provoquer ladite réaction endothermique, ce qui va entraîner la baisse de la température de la paroi du boîtier et de la partie en saillie (2). Une réfrigération préalable au réfrigérateur est inutile et le refroidissement peut se prolonger pendant un certain temps tant que la réaction se poursuit, si bien que cet instrument de traitement des hémorroïdes est pratique à utiliser et reste froid longtemps.
