20090204102 | INTRADERMAL SYRINGE AND NEEDLE ASSEMBLY - A method for using a needle assembly for an intradermal injection, and a drug delivery device is provided, which includes a needle cannula and a limiter surrounding the needle cannula and includes a skin engaging surface on the limiter. The limiter is moveable from a first position in which an elongate portion of the needle cannula is exposed for access to a medication vial, to a locked second position in which the limiter is not movable from the second position to the first position. In the second position, the needle tip extends beyond the skin engaging surface a distance of about 3 mm or less. | 08-13-2009 |
20090292257 | Safety Shield System for Prefilled Syringe - A medical device is provided which includes a shield system and a syringe which is coupled to the shield system. The shield system includes a syringe holder and a shield which is slidably coupled to the holder. A spring resiliently urges the shield from a retracted position to an extended position. Stop members are provided on the holder and shield for maintaining the shield in the retracted position. The syringe is slidably coupled to the holder, and extends within the shield. Axial movement of the syringe with respect to the holder causes disengagement of the stop members, allowing the spring to move the shield to the extended position. Detents are provided on the holder for maintaining the shield in the extended position. | 11-26-2009 |
20090299325 | Filling System and Method for Syringes with Short Needles - A filling system for syringes utilizing short needles to be filled from a vial having a thick septum is described. The system may be useful in any situation where the septum or vial stopper of a medication container is thicker than the usable length of the needle on the delivery device. Preferably, the syringe is filled just prior to use. The short needle includes an optional limiter which only permits a certain predetermined length of the needle cannula to protrude beyond the limiter a distance which limits penetration of the needle tip into both the skin and a vial stopper. The system and adapter may be useful for needles having a protrusion distance from approximately 0.5 mm to 3 mm, or any needle with a protrusion length shorter that the thickness of a septum to be accessed. Furthermore, a device is provided with shielding capabilities to shield the needle of the device. | 12-03-2009 |
20100030148 | Intradermal Delivery Device With Crenellated Skin Engaging Surface Geometry - An apparatus for delivering or withdrawing a fluid through at least one layer of the skin is provided. The device may include a body having a top face, a bottom face, a side edge and at least one channel. The bottom face includes a first surface area and a second surface area adjacent to and recessed at a first distance from the first surface area. The bottom face further includes at least one raised protrusion disposed on the second surface area. The protrusion has a height from the first surface greater than the first distance. At least one dermal-access member is provided in the protrusion and is in fluid communication with the channel to deliver or withdraw the fluid. | 02-04-2010 |
20140018734 | Intradermal Delivery Device With Crenellated Skin Engaging Surface Geometry - An apparatus for delivering or withdrawing a fluid through at least one layer of the skin is provided. The device may include a body having a top face, a bottom face, a side edge and at least one channel. The bottom face includes a first surface area and a second surface area adjacent to and recessed at a first distance from the first surface area. The bottom face further includes at least one raised protrusion disposed on the second surface area. The protrusion has a height from the first surface greater than the first distance. At least one dermal-access member is provided in the protrusion and is in fluid communication with the channel to deliver or withdraw the fluid. | 01-16-2014 |
20140074064 | INTRADERMAL DELIVERY DEVICE INCLUDING A NEEDLE ASSEMBLY - A drug delivery device including a needle assembly facilitates making intradermal injections using a variety of drug container types such as a syringe. A hub supports the needle while a limiter surrounds the needle. The limiter includes a skin engaging surface that is adapted to be received against the skin of an animal to be intradermally injected. A forward end of the needle extends beyond the skin engaging surface a selected distance to limit a depth that the needle penetrates into the animal's skin. | 03-13-2014 |
20150100022 | Intradermal Injection Device - An intradermal injection device comprising a unitary body having an open distal end and a proximal end having a skin engaging surface defined thereon, a reservoir defined between the proximal and distal ends for accommodating a drug substance, and a channel defined at the proximal end of the unitary body and extending through, and distally from, the skin engaging surface to the reservoir. A needle cannula having a sharpened proximal end and a distal end may be provided in the channel. The needle cannula is secured in the channel with the distal end being in communication with the reservoir and the proximal end of the needle cannula extending from the skin engaging surface a distance in the range of about 0.5 mm to 3.0 mm such that the skin engaging surface limits penetration of the proximal end of the needle cannula to the dermis layer of the skin of a patient. | 04-09-2015 |
