An automatic medication injection device that provides a user with audible notice of injecting progress. The device in one form includes a plurality of sound elements located on drive mechanism portion that inserts within a barrel of a container of medication to advance a sealing plunger of that container. The device also includes at least one actuating element movable axially with the container of medication within the device housing, which at least one actuating is element arranged to engage the plurality of sound elements to generate audible notices as the advancing portion moves past the at least one actuating element when advancing the sealing plunger for an injection.

A puller assembly for removing a shield from around a needle of a syringe. The puller assembly includes a grip component and a cap. The grip component has a tubular body defining an interior hollow which axially receives the shield. The tubular body has a slit that allows it to be forcibly shifted from a first arrangement to a second arrangement to change the size of the interior hollow. The tubular body includes a radial inner face with at least one radial inward projection for directly engaging the shield. The cap is grippable by a user. The grip component is held by the cap when inserted within a cavity of the cap during manufacturing installation, and when so held at least one radial inward projection of the grip component engages the shield for removal of the shield from around the needle when the cap is moved. A method of mounting a puller assembly to a shield around a needle is also disclosed.

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.

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.

Process and device for delivery of fluid by chemical reaction

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.

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.

An assessment device is provided which allows for measurement of a position of interest, e.g., a body part, while a subject is in a functional position, such as may be required for the demands of an activity of interest without also requiring a lengthy setup time, tethered connection to other equipment external to the subject or tedious manual measurements. Moreover, an indicator such as an alarm or other output may be provided for receiving immediate, real time feedback, such as when a functional activity falls outside a tolerance or threshold.
