FLUID INFUSION METHOD AND SYSTEM THEREFOR
First Claim
1. A system for delivering a fluid into the body of a patient, the system comprising:
- a sheet having oppositely-disposed first and second surfaces;
means for securing the sheet to a surface of the body of the patient so that the first surface of the sheet is held in contact with the surface of the body;
a reservoir supported on the sheet and containing the fluid;
a flow sensing device supported on the sheet and fluidically coupled to the reservoir, the flow sensing device generating at least one output signal based on flow of the fluid through the flow sensing device;
means supported on the sheet for initiating and interrupting flow of the fluid from the reservoir and through the flow sensing device;
means supported on the sheet and fluidically coupled to the flow sensing device for introducing into the body through the surface thereof the fluid that flows from the reservoir and through the flow sensing device;
electronic circuitry supported on the sheet and having means for receiving the output signal from the flow sensing device and means for controlling the flow initiating and interrupting means; and
means supported on the sheet for powering the flow sensing device, the flow initiating and interrupting means, and the electronic circuitry.

Abstract
A system and method for delivering a precise amount of fluid, such as a fluid for medical treatment. The system is a compact, fully-integrated, assembly that includes a sheet configured to be secured to a patient so that a surface of the sheet is held in contact with the patient'"'"'s skin. The sheet carries a reservoir containing the fluid, a flow sensing device fluidically coupled to the reservoir, a device for initiating and interrupting flow of the fluid from the reservoir to the flow sensing device, a device for introducing the fluid into the patient'"'"'s body, electronic circuitry for controlling fluid flow based on the output of the flow sensing device, and a power source.
