摘要： Disclosed is an infusion pump for expelling a fluid from a collapsible fluid reservoir to a patient. The pump includes a housing having a chamber therein for receiving the fluid reservoir. A first wall is provided on the housing for contacting the fluid reservoir, and a second wall is movable from a first position distanced from the first wall to form the chamber therebetween, and a second position relatively closer to the first wall. Advancing the movable wall from the first position to the second position expels fluid from the collapsible reservoir at a substantially constant rate by applying increasing force on the fluid reservoir through the dispensation cycle. Preferably, the first and second walls are provided with non-planar complementary surface configurations for contacting the collapsible reservoir. Retraction mechanisms for retracting the movable wall from the second position to the first position, and user readable indicium of the status of the dispensation cycle are also disclosed.

摘要： A fluid delivery device is provided for transdermal delivery of fluid medications to patients. The device comprises a thin envelope which is applied to a patient's skin. The envelope comprises at least one diffusion layer coupled to at least one impermeable layer such that at least one chamber exists therebetween. Other embodiments include internal diffusion layers, and thus possess additional chambers, as well. The impermeable layer comprises a top surface of the device. A valve positioned in the impermeable layer facilitates filling the device with fluid, as well as connection of the device to external fluid sources such as an intravenous bag, pump, or other external fluid delivery system. The diffusion layer may comprise a semi-permeable membrane which controls the rate of fluid flow from the device to the patient's skin.
摘要翻译：提供流体递送装置用于向患者透皮递送流体药物。该装置包括施加到患者皮肤上的薄膜。该包络线包括至少一个与至少一个不可渗透层耦合的扩散层，使得至少一个室存在于其间。其他实施方案也包括内部扩散层，因此也具有另外的室。不透水层包括该装置的顶表面。定位在不渗透层中的阀有助于用流体填充装置，以及将装置连接到诸如静脉内袋，泵或其它外部流体输送系统的外部流体源。扩散层可以包括半透膜，其控制从装置到患者皮肤的流体流速。

摘要： A fluid delivery device for transdermal delivery of a fluid to a patient. The device comprises an envelope that may be applied to a patient's skin. The envelope comprises at least one diffusion layer coupled to at least one impermeable layer such that at least a chamber is defined therebetween. Other embodiments include internal diffusion layers, and thus possess additional chambers, as well. In one arrangement, an adhesive boundary layer permits the device to be removably secured to a patient and inhibits radial migration of fluid beyond the periphery of the device. In another arrangement, preferably, an anti-microbial layer is provided to inhibit the growth of microorganisms.
