    • A transdermal patch that can easily deliver a controlled volume of a fluidic drug compound to the skin is provided. More particularly, the patch contains a microneedle assembly that is configured to be placed in fluid communication with a drug delivery assembly. The microneedle assembly contains a support and a plurality of microneedles that extend outwardly from the support. The microneedles are formed with one or more channels of a certain dimension such that passive capillary flow drives the flow of the drug compound. The drug delivery system contains a reservoir for the drug compound that is in fluid communication with -a rate control membrane that helps control the flow rate of the drug compound by modulating its pressure downstream from the reservoir. A release member is also positioned adjacent to the microneedle and drug delivery assemblies. Prior to use, the release member acts as a barrier to the flow of the drug compound and thus inhibits premature leakage. In this manner, the patch can initially be provided in an "inactive" configuration in which the drug compound is securely retained. When it is desired to release the drug compound, the patch can simply be activated by at least partially separating the release member from the drug delivery and microneedle assemblies.
    • 提供了可以容易地将受控体积的流体药物化合物递送至皮肤的透皮贴剂。 更具体地,补片包含配置成与药物输送组件流体连通的微针组件。 微针组件包含支撑件和从支撑件向外延伸的多个微针。 微针形成有一个或多个具有一定尺寸的通道,使得被动毛细管流驱动药物化合物的流动。 药物递送系统包含与速率控制膜流体连通的药物化合物的储存器,其通过调节其从储存器下游的压力来帮助控制药物化合物的流速。 释放构件也邻近微针和药物输送组件定位。 在使用之前,释放构件作为药物化合物流动的屏障,从而抑制过早的渗漏。 以这种方式,补片最初可以以其中药物化合物被牢固地保持的“无活性”构型提供。 当需要释放药物化合物时,可以通过至少部分地将释放构件与药物递送和微针组件分离来简单地活化贴剂。

    • A controller, which may be used in a transdermal drug delivery apparatus, includes a housing, a pushing mechanism mounted for moving relative to the housing, a force provider positioned between the housing and the pushing mechanism for moving the pushing mechanism relative to the housing, and a latching mechanism for selectively restricting and allowing relative movement between the housing and the pushing mechanism. The pushing mechanism may be configured for pushing against a reservoir of the transdermal drug delivery apparatus. The latching mechanism may include flexible arms extending between the opposite ends of the latching mechanism, and the latching mechanism may be configured so that the arms release the pushing mechanism in response to the opposite ends being forced toward one another.
    • 可用于透皮药物输送装置的控制器包括壳体,安装成相对于壳体移动的推动机构,位于壳体和推动机构之间的力提供件,用于相对于壳体移动推动机构, 以及用于选择性地限制和允许壳体和推动机构之间的相对运动的闭锁机构。 推动机构可以被配置为推动透皮药物递送装置的储存器。 闩锁机构可以包括在闩锁机构的相对端部之间延伸的柔性臂,并且闩锁机构可以被构造成使得臂相对于相对的端部被迫朝向彼此而释放推动机构。
