    摘要： A method for injecting a substance through a biological body surface includes providing a needle-free transdermal transport device configured to inject the substance through the surface. The substance is injected into the biological body with the transport device while a parameter of the injection is sensed and a servo-controller is used to dynamically adjust at least one injection characteristic based on the sensed parameter. The substance is injected for (i) a first time period during which a first portion of a volume of the substance is injected at a first injection pressure, and (ii) a second time period during which a remainder of the volume of the substance is injected at a second injection pressure. A viscosity of the substance may be determined, and a pressure calculated for injecting the substance based on the viscosity. The substance may be injected with the transport device by using the calculated pressure.

    摘要： A pressure system in a communication loop with an atmospheric pressure data source is set forth. Atmospheric pressure data from the atmospheric pressure data source can be received by a processor to set one or more operating parameters for the pressure system based on environmental data provided in the atmospheric pressure data from an absolute pressure sensor or other atmospheric data source.

    摘要： Systems for managing pressure in a fluid reservoir chamber of a fluid infusion device are provided. For example, a fluid infusion device is provided. The fluid infusion device comprises a housing defining a reservoir chamber for receiving a fluid reservoir. The fluid infusion device also comprises a drive system contained within the housing for dispensing fluid from the fluid reservoir. The fluid infusion device comprises a pressure management system at least partially defined in the reservoir chamber to manage air pressure in the reservoir chamber.
