Summary:The present invention relates to a dissolvable microneedle comprising needles made of a water-soluble material assembled on one side of a base, which is a sheet material having liquid-permeable cavities, wherein the needles being assembled to the base such that bottom portion of the needles is directly connected to the base, the connection of the bottom portion of the needle s to the base forming through a structure in which the bottom portion of the needles penetrates into the base (102), occupying some or all cavities of the base. The dissolvable microneedle with the structure according to the present invention is convenient to use as the penetrating structure that connects the needle s to the base can be dissolved quickly and efficiently; therefore, the base can be removed from the top skin without the needles embedded within the skin being pulled out. Hence, there is no clearly visible remainder on the top skin, and the active agent contained in or coated on the needles can also be released more effectively. La presente invención se refiere a una microaguja disoluble que comprende agujas hechas de un material hidrosoluble ensamblado en un lado de una base, que es un material de lámina que tiene cavidades permeables por líquidos, en donde las agujas son ensambladas a la base de tal manera que la porción inferior de las agujas esté directamente conectada a la base, la conexión de la porción inferior de las agujas a la base siendo formada mediante una estructura en donde la porción inferior de las agujas penetra en la base (102), ocupando algunas o todas las cavidades de la base. La microaguja disoluble con la estructura de acuerdo con la presente invención es conveniente para usar ya que la estructura penetrante que conecta las agujas a la base puede disolverse rápida y efectivamente; por lo tanto, la base puede retirarse de la parte superior de la piel sin que las agujas incrustadas dentro de la piel se retiren. Por lo tanto, no hay residuos claramente visibles en la parte superior de la piel, y el agente activo contenido o recubierto en las agujas también se puede liberar más efectivamente.
