Embodiments herein relate to the field of injections, for instance needle-free injections, and more specifically, to methods and apparatus for spring-driven intramuscular and intradermal injections. Provided in some embodiments are needle-free injectors adapted to deliver intradermal injections, as well as vial adaptors that are adapted to function as spacers when used with a needle-free injection device.

Intradermal injection device

A needle-free injection device is described. The injection device includes a user-grippable housing and a syringe assembly movably secured to the housing. The syringe assembly is configured to expel injectable fluid out of a nozzle upon application of pressurized gas to the syringe assembly. The injection device also includes a pressurized gas delivery mechanism disposed within the housing and configured to selectively apply pressurized gas to the syringe assembly. The pressurized gas delivery mechanism is at least partly actuated by pressing the nozzle onto an injection site so that the syringe assembly moves relative to the housing.

Needle-free injection system

A method and apparatus for providing high throughput injections is provided. The invention provides a filling device adapted to deliver injectate from a common reservoir to a plurality of disposable fluid injection assemblies and a reusable propulsion assembly adapted to receive a filled disposable fluid injection assembly and deliver an injection to a patient.

A digital audio player has a removable and interchangeable multi-function module that has at least one operating member. The multi-function interchangeable module interoperates with the body of the digital audio player to provide a plurality of features, which include, but are not limited to, additional memory storage, radio tuner, display, Infrared transceiver and wireless transceiver.

Noninvasive-blood-pressure (NIBP) monitoring apparatus is disclosed which is usable to perform either oscillometric or auscultatory NIBP. The apparatus includes relatively adjustable, noninflatable, pressure-information-providing (PIP) structure usable to apply NIBP-useful pressure to such limb adjacent such vessel. Also included is pressure-changer structure associated with the PIP structure, and operable to adjust the same to a beginning NIBP-useful pressure, and to subsequent NIBP-useful pressures, with such adjustment effecting the availability of pressure information that can be sensed by such sensor structure. The apparatus is preferably constructed for oscillometric NIBP monitoring and includes a reaction band removably fittable on and circumscribingly about the limb of such living subject. The preferred construction is for portable, self-contained, ambulatory usage. Other embodiments include providing an output communicator for sending NIBP-data signals in various outputs including electrical, wireless and optical, and visually perceptible ones.
