A removal device (121, 221) for removing and disposing of a pen needle (113, 213) connectable to a drug delivery device (111, 211) includes a body (123, 223) having a cavity (141, 241) for receiving the pen needle of the drug delivery device such that a patient end (116, 216) of a needle (115, 215) of the pen needle is covered by the body. An ejector (151, 251) is movably connected to the body (123, 223) for engaging the received pen needle (113, 213) and selectively ejecting the engaged pen needle from the body. The pen needle (113, 213) is securely retained within the removal device (121, 221) without exposing the needle (115, 215) of the pen needle until the pen needle (113, 213) can be properly disposed of, such as in a sharps container, thereby substantially preventing an accidental needle stick.

A safety insulin pen needle includes a needle body, intermediate shield, front shield, tail cover, rear spring, and rotating tube. The rotating tube includes a beveled rail, and the front shield includes a bevel acting part that interacts with the beveled rail. The tail cover includes an elastic leg, which includes a rear protection stopper. The rotating tube includes a first and second rail slot spaced apart along a circumferential direction, which interact with the rear protection stopper. Backward movement of the front shield when the needle is pushed rotates the rotating tube and uses the interaction of the first and second rail slot on the rotating tube and the rear protection stopper on the tail cover to change the relationship between the tail cover and the rotating tube, which provides reliable locking protection of the tail cover after use.

A device for cutting, separation, and discharge of a syringe according to an embodiment of the present disclosure includes a barrel unit, a main body including a driving unit configured to rotate the barrel unit, and a cutting body configured to cut a needle portion of a syringe during rotation of the barrel unit, wherein transfer of the syringe inserted into the barrel unit, cutting of the needle portion, discharge of the needle portion, and discharge of a syringe main body are performed by only one rotation of the barrel unit.

One embodiment is directed to a system for injecting, comprising a syringe body defining an interior medicine chamber; a stopper member configured to be inserted into the interior medicine chamber to contain medicine within the medicine chamber; a plunger member configured to be manually manipulated to insert the stopper member relative to the syringe body; and a needle having proximal and distal ends, the proximal end comprising an anchoring geometry configured to be at least partially inserted into the stopper member such that upon retraction of the stopper member, the needle is pulled proximally along with the stopper to be at least partially contained within the interior medicine chamber.

A syringe with high safety in use having a syringe body adapted to accommodate slidingly a plunger. The syringe body has a protruding end that is adapted to allow the mating of a base end of a needle. The syringe further includes elements for removing the needle and/or a cap interposed between the syringe body and the base end of the needle. The needle removal elements are adapted to be moved in a rotary direction for removal of the needle and/or the cap.

One embodiment is directed to a system for injecting, comprising a syringe body defining an interior medicine chamber; a stopper member configured to be inserted into the interior medicine chamber to contain medicine within the medicine chamber; a plunger member configured to be manually manipulated to insert the stopper member relative to the syringe body; and a needle having proximal and distal ends, the proximal end comprising an anchoring geometry configured to be at least partially inserted into the stopper member such that upon retraction of the stopper member, the needle is pulled proximally along with the stopper to be at least partially contained within the interior medicine chamber.

Provided is a puncture needle that receives lower puncture resistance than conventional techniques. A puncture needle in accordance with an aspect of the present invention includes a needle body (10) that includes a main portion (12) and a distal portion (11) tapering from the main portion (12) and that is rotatable about a central axis (1) of the needle body (10), the needle body (10) including needle parts (15) separated by a boundary along the central axis, each of the needle parts (15) being independently translatable along the central axis (1).

A safe needle separator for a dental syringe includes: a basket having an internal storage space with an open top; a fixing shaft vertically disposed on a bottom inside the basket; and a rotary plate rotatably disposed on an upper end of the fixing shaft and having a holding hole in which a needle head of a dental syringe is inserted and fixed so that when a user holds a dental syringe and turns the rotary plate clockwise with a needle head fixed in the holding hole, the needle head thread-fastened counterclockwise to the dental syringe is separated from the dental syringe and dropped into the storage space.
