Fluid medication delivery device
First Claim
1. A fluid medication delivery device, comprising:
- a fluid impermeable pouch having first and second opposing walls, the first wall and the second wall defining a space therebetween, the space defining a fluid reservoir of the delivery device, the second wall including a plurality of openings therethrough defining a diffusion area of the delivery device;
a coiled wire member covering at least the diffusion area of the delivery device, the coiled wire member comprising a plurality of adjacent wire sections defining a plurality of gaps therebetween, the coiled wire member being configured such that fluid within the fluid reservoir must pass through the plurality of gaps between the adjacent wire sections of the coiled wire member before exiting the delivery device through the plurality of openings in the second wall.

Abstract
A fluid delivery device is provided for transdermal delivery of fluid medications to patients. The device can comprise a thin envelope which is applied to a patient'"'"'s skin. The envelope can comprise at least one diffusion layer coupled to at least one impermeable layer such that at least one chamber can exist therebetween. Other embodiments can include internal diffusion layers, and thus can possess additional chambers, as well. The impermeable layer can comprise a top surface of the device. A valve positioned in the impermeable layer can facilitate 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 can comprise a coiled wire member to control the rate of fluid flow from the device to the patient'"'"'s skin.
