    摘要： An injector is disclosed for injecting an injectable substance into at least one of the epidermal tissue and the dermal tissue of a subject. The injector includes an outer housing and a control member disposed within the outer housing. A needle head, which is configured to support a plurality of needles, is operatively coupled to the control member. First means are provided in communication with the control member and are configured to be driven by the control member for converting a movement of the control member into a movement of the needle head along an injection direction and toward an injecting position of the needle head. Second means are configured to move the needle head in a direction having a component that is normal to the injection direction and absent movement of the outer housing relative to the skin of the subject.

    摘要： A pen needle assembly apparatus (60) includes a housing (30), a movable support (40) for supporting a pen needle (18), an ejector (80) for ejecting a used pen needle from the support, and an actuator (56). The support (40) is rotated relative to the housing (30) to index the pen needles to a position where the pen needle can be accessed and coupled to a delivery device (10). The used pen needle (18) is returned to the well (42) in the support and the support rotated toward the ejector (80) where the used pen needle is ejected to a compartment (50) in the housing for disposal. A cover (60) on the housing includes at least one opening (65) for accessing the pen needle when the support is rotated to position a pen needle relative to the opening in the cover.

    摘要： This device is a compressible chamber designed to inject a liquid medication through a plurality of needles. It is a self-contained, rapidly deployed device that replaces a classic syringe. It consists of a shallow chamber that is closed on one end and sealed on the other with a sliding elastomeric seal. A rigid ring slides up into the chamber that has multiple small double-ended needles mounted through the periphery of the ring perpendicularly so as to be able to perforate the seal of the chamber with the proximal end and simultaneously penetrate the subcutaneous tissues with the distal end thus allowing medication to flow from the chamber into the tissues when pressure is applied to the top of the chamber. The needles are also imbedded in, or juxtapose to a ring of compressible dye-containing material that serves to conceal the needles and provide demarcation of the area injected.

    摘要： In accordance with preferred embodiments, a needle with gated stylet is provided that is useful for controlled fluid transfer with a patient's body. Preferably, the needle with gated stylet includes a hollow core needle providing a needle tip and at least two fluid transfer apertures with the stylet removably disposed within the needle. In an alternate embodiment, a needle providing a hollow core, an insertion tip, and a fluid transfer aperture adjacent the insertion tip and communicating with the hollow core, and a stylet disposed within the hollow core, cooperating with the fluid transfer aperture to preclude fluid flow through the fluid transfer aperture when the stylet is in a first position adjacent the insertion tip and promote fluid flow through the transfer aperture when the stylet is in a second position adjacent the insertion tip.
