摘要： A drug formulation chamber for an intravenous administration set is provided. The intravenous administration set includes a container of an IV fluid, a drip chamber, a drug formulation chamber, and an adapter-needle assembly. The drug formulation chamber has a fluid inlet and a fluid outlet for maintaining a flow of IV fluid through the chamber. A portion of the chamber wall is comprised of a material which is permeable to the drug but which prevents convective loss of the IV fluid. A transdermal-type drug delivery device is adhered to the semipermeable/microporous wall portion. Drug is delivered by the delivery device through the wall portion and into the flowing IV fluid. The device delivers drug into the IV fluid at a rate that is independent of the flow rate of IV fluid through the formulation chamber. The rate of drug delivery from the device into the IV fluid is controlled by either the wall portion or a membrane layer in the drug delivery device. A plurality of drug delivery devices may be adhered to the wall portion to deliver a plurality of drugs or to deliver a single drug at a higher dosage rate.

摘要： A dispenser for use in a fluid environment which is capable of delivery of plurality of discrete drug containing layers in any desired delivery pattern or profile. The dispenser comprises a rigid housing containing a plurality of drug layers which may be separated by drug-free layers. An outlet is provided at one end of the housing and a fluid actuated driving means is provided between the other end of the housing and the drug layers. The portion of the housing in proximity to the driving means has a controlled permeability to water whereby, upon immersion in a fluid environment the drug layers are driven towards the outlet. Various delivery patterns are possible by appropriate selection of the comparison and dimensions of the drug and drug-free layers.
摘要翻译： 一种在流体环境中使用的分配器，其能够以任何期望的输送模式或轮廓递送多个离散的含药层。 分配器包括容纳多个药物层的刚性壳体，其可由无药物层分离。 出口设在壳体的一端，并且流体驱动的驱动装置设置在壳体的另一端和药物层之间。 壳体靠近驱动装置的部分对水具有受控的渗透性，因此当浸入流体环境中时，药物层朝着出口被驱动。 可以通过适当选择药物和无药物层的比较和尺寸来实现各种递送模式。
