Abstract
Las cápsulas de suministro, que incluyen un agente benéfico y un mecanismo activador en departamentos separados por una división movible, están diseñadas através de una manera pulsátil, através de un orificio. Se logra el suministro pulsátil mediante un par de miembros de guía, dentro de la cápsula, uno de los cuales está asegurado a la propia cápsula y el otro a la división movible. Los miembros de guía, que pueden ser una flecha y un manguito, una flecha y un anillo, o alguna combinación similar de elementos, guían el movimiento de la división a lo largo del eje de la cápsula. El movimiento puede ser lineal o de rotación a la manera del tipo de tornillo, dependiendo de si la flecha está roscada o no. Se forma una serie de limitadores o retenes en los miembros de guía, y uno o más fiadores o miembros acopladores de retén, está formado en el otro miembro. Los fiadores comprueban el movimiento de la división y permiten que dicho movimiento ocurra por pulsos, a medida que aumenta la presión por encima de un nivel de umbral. El número y la separación de los retenes establece el número y la frecuencia de los pulsos, y la función pulsante opera independientemente del contacto sellador entre la división y la pared interna de la cápsula.The delivery capsules, which include a beneficial agent and an activating mechanism in departments separated by a movable partition, are designed through a pulsating way, through a hole. Pulsed delivery is accomplished by a pair of guide members, within the capsule, one of which is secured to the capsule itself and the other to the movable partition. The guide members, which may be an arrow and a sleeve, an arrow and a ring, or some similar combination of elements, guide the movement of the partition along the axis of the capsule. The movement can be linear or rotational in the manner of the screw type, depending on whether the arrow is threaded or not. A series of limiters or retainers is formed on the guide members, and one or more detent or catch coupler members is formed on the other member. The catches check the movement of the division and allow the movement to occur by pulses, as the pressure rises above a threshold level. The number and spacing of the retainers sets the number and frequency of the pulses, and the pulsing function operates independently of the sealing contact between the partition and the inner wall of the capsule.
