An access needle well-suited for percutaneous implantation in a body lumen, such as the stomach or the jejunum. In one embodiment, the access needle comprises a cannula, a needle, a retractable stopper and a spreader. The cannula is a tubular member having a proximal end, a distal end, a lumen and a pair of side windows providing access to the lumen. The needle is slidably mounted within the cannula lumen and comprises a needle stem and a needle handle, the needle stem having a proximal end, a distal end and a longitudinal lumen, the needle handle extending outwardly from the needle stem proximate to the proximal end thereof. The stopper is coupled to the needle stem for translational movement, the stopper comprising a pair of outwardly-biasing wings removably insertable through the side windows for engaging an interior surface of a patient. The spreader is mounted within the cannula and spreads the wings outwardly as the wings are inserted out the side windows.

An autoinjector device for delivering a dose of medicament including a syringe including a needle wherein, prior to use of the device, the needle is substantially covered by a needle sheath (107). The autoinjector further includes a housing (112) in which said syringe is located, an outer packaging in which said housing is located, where the outer packaging comprising a front packaging (101) part and a rear packaging part. The autoinjector also includes needle sheath removing means (103) associated with said front packaging part (101), wherein, prior to use of the device, said front and rear packaging parts cooperate together to entirely enclose said housing, syringe and needle sheath, and wherein, upon axial separation of said front and rear packaging parts, said needle sheath removing means is capable of causing axial separation of said needle sheath from said needle so as to remove said needle sheath therefrom.

A needle magazine for holding a plurality of injection needles (50) is described. The needle magazine comprises a first opening adapted to receive the device fluid access portion (120) of a medical delivery device. Each needle (50) is selectively moveable from a respective storage position not aligned with said first opening into a needle mounting position aligned with said first opening. The needle magazine further comprises needle positioning means (41). configured to alter the mutual position between a needle selected from said plurality of needles (50) relative to a neighbour needle when said selected needle moves from its storage position to the needle mounting position.

To ensure that there is no misconnection between a needle, such as for example a spinal or epidural needle, and the appropriate medication, the needle hub the needle is formed, by molding or extrusion, to have a given configuration. An adapter is placed between the needle and a conventional fluid store, or medical line. The end of the adapter that connects to the needle assembly is formed to have a configuration that is complementary to that of the hub of the needle assembly, so that the adapter and the needle hub may be readily mated to each other. The other end of the adapter is formed to have another configuration, for example a conventional luer, that is readily connectable to a conventional fluid store, such as a syringe that has a conventional luer. The adapter is formed by inter-fitting two elements to effect an integral locking mechanism to prevent the uncoupling of the fluid store and the adapter, once they are securely coupled. By thus configuring the hub of the needle to have a given configuration that is matable only to the end of an adapter that has a complementary configuration, and further providing an adapter that prevents the removal of the fluid store connected thereto, the potential for mis-connecting the needle to a fluid store that contains a different medicament is greatly reduced, if not totally eliminated.

A safety enclosure which is designed for a hypodermic needle that is located in the shape of an approximate right angle (Huber needle). A safety enclosure has a needle housing within which the Huber needle is mounted. The needle housing is mounted in conjunction with a panel unit. The panel unit is composed of a series of planar panels which are edge connected together defining an enclosed area. The panel unit can be movable from a basically transverse position to an elongated position. When in the transverse position, the panel unit is to be mounted with adhesive tape onto the skin of a patient with the sharp end of the needle being inserted within the body of the patient. When the panel unit is in the elongated position, the needle is withdrawn from the body of the patient and the sharpened end of the needle is covered by the panels thereby preventing undesired needlestick injury to the medical practitioner that is installing and removing the enclosure.
