Abstract: An assembly for use with a syringe having a barrel and a needle includes a sealing element surrounding and positioned over at least a portion of the distal end of the syringe. An adapter at least partially surrounds the sealing element and is positioned over the distal end of the syringe. The adapter has a first skin contacting surface positioned at a distal end thereof. At least a portion of the first skin contacting surface extends generally parallel to at least a terminal end of the needle. The adapter also has a second skin contacting surface positioned proximally relative to the terminal end of the needle and at an angle to the first skin contacting surface. A needle shield at least partially surrounds and is removably positioned over at least one of the adapter, the sealing element and the syringe barrel.

Abstract: An intradermal injection assembly for injecting a medicament into skin could form an intradermal needle with an adapter, an intradermal syringe with an adapter or an adapter for a merger with a syringe with a cannula. The intradermal adapter in these devices has a body having a longitudinal axis, a central portion having a cannula channel and a distal protrusion extending generally parallel to the longitudinal axis. The distal protrusion of the adapter has a first skin contacting surface extending generally parallel to the longitudinal axis. At least a portion of the distal protrusion is generally transparent such that the portion of the cannula that extends distally relative to a demarcation plane can be viewed through the distal protrusion during insertion of the cannula into a patient's skin.

Abstract: An intradermal injection adapter includes a body having a longitudinal axis and a central portion located distally relative to the body along the longitudinal axis. The central portion has a cannula channel therethrough extending generally parallel to the longitudinal axis. A cannula within the cannula channel has a sharpened tip for injection into a patient and a sharpened opposite proximal end for injection into a pen injector. A distal protrusion has a first skin contacting surface extending generally parallel to the longitudinal axis. The first skin contacting surface is spaced from the cannula such that a distal portion of the cannula extends generally parallel to the first skin contacting surface.

Abstract: Devices and methods for intradermal (ID) administration of diagnostic and therapeutic agents, vaccines and other compounds into the dermal layer of the skin are disclosed. The devices and the methods simplify the ID injection process and increase the consistency of the placement of the needle tip in the dermal space close to the skin surface allowing for a shallow cannula placement in the dermis. Furthermore, the devices and methods broaden the number of sites suitable for ID injection and make the ID injection possible with limited training.

Abstract: An adapter device (100, 200) for use in combination with a syringe (20) to form an assembly (10) for delivering an intradermal injection. The adapter device comprises a body (110, 210) which is connectable to the syringe. A second primary skin contacting surface (232) is positioned at a distal end (126, 226) of the body. At least one support element (140, 150, 240) is connected to the body. With the assembly in an assembled condition, the at least one support element supports a needle cannula (24) connected to the syringe. The needle cannula is supported by the at least one support element intermediate a base (26) and a tip (28) of the needle cannula. At least a terminal portion of the needle cannula extends axially in a direction substantially parallel to at least a planar portion of the second primary skin contacting surface.

Abstract: An injector is automatic in that the needle is inserted into the injection site (e.g., a patient's skin) with user or caregiver assistance, the delivery is automatically initiated upon needle insertion, and the needle is retracted automatically after the end of delivery. Preferably the needle is not seen by the user prior to, during or after injection. Prior to and after injection, the needle is hidden in the device so as to avoid any potential injury or health risk to the user or health care provider. The injector includes a housing and a shield arranged to slide relative to the housing and a driver moving during drug delivery. The housing and shield form a cartridge enclosure. The cartridge is shielded and locked after delivery is completed. A needle-locking mechanism can be used in any number of pen-like injectors or safety needles.
