Abstract: Injection devices with ergonomic enhancements are disclosed. Generally, the injection devices include large oversized grips, including flanges at the base end of the device for enhanced stability. Push-type and squeeze-type devices are described, as well as manual injectors and auto-injectors. Such injection devices are useful for delivering a fluid (e.g. medication) to a patient.

Abstract: Processes and devices for delivering a fluid by chemical reaction are disclosed. A chemical reaction is initiated in a reaction chamber to produce a gas, and the gas acts upon a piston to deliver the fluid. An exemplary device may include an upper chamber, a lower chamber, a fluid chamber, a piston between the lower chamber and the fluid chamber, and a one-way valve between the upper chamber and the lower chamber.

Abstract: Processes and devices for delivering a fluid by chemical reaction are disclosed. A chemical reaction is initiated in a reaction chamber to produce a gas, and the gas acts upon a piston to deliver the fluid. Preferred devices typically include an upper chamber, a lower chamber, a fluid chamber, a piston between the lower chamber and the fluid chamber, and a barrier between the upper chamber and the lower chamber. When the barrier is broken, reagents in the upper chamber and the lower chamber are mixed together to generate the gas.

Abstract: Chemical engines and processes for their use and construction are described. The chemical engines can provide powerful and compact devices, especially autoinjectors for the rapid, powered injection of viscous medicines. Novel formulations and designs of chemical engines and delivery technologies employing the chemical engines are described.

Abstract: A three contact barrel power connector assembly is provided. The power connector assembly includes both a connector plug and a connector jack. The connector plug includes an inner body and an outer body transmitting electrical current. The connector plug further includes a center body that transmits a data signal or a low power current. The connector jack includes a housing ground, a housing body, outer contacts that couple with the outer body, inner contacts that couple with the inner body, and a center contact that couples with the center body. The power connector assembly further includes insulators operable to prevent unwanted electrical contact between the connector plug and the connector jack. The connector plug is operable to couple with the connector jack independent of the orientation of the connector plug with respect to the connector jack, provide high levels of power, and effectively transmit data signals in addition to power.

Abstract: An AC adapter connector assembly is provided. The connector assembly includes both a connector plug and a socket. The connector plug includes a connector housing having a first body and a second body both extending from the connector housing. The second body is offset and in alignment with the first body. A first pin aperture and a third pin aperture are disposed within the first body while a second pin aperture is disposed within the second body. The socket assembly includes a socket housing having a first aperture and a second aperture offset from the first aperture. A first pin and a third pin are disposed within the first aperture and a second pin is disposed within the second aperture. The connector plug assembly is operable to couple with the socket assembly in a specific orientation and support both a three wire power cord and a two wire power cord.
