A fluid transfer device such as a syringe may include a fluid chamber in communication with a male connector tip. The male connector tip is tapered to form a friction fit when inserted in a corresponding female hub. A disconnecting member, e.g., in the form of a lever member has a front surface moveable along the male connector tip between a first position proximal to the fluid chamber and a second position spaced from the first position towards a distal end of the male connector tip so as to release the friction fit. A catch is arranged to catch the female hub after it has been released from the friction fit by the lever member moving towards the second position. The catch may be released when the lever member pivots back towards the first position under the resilient bias of a spring tongue.

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.

The invention discloses a plastic injection syringe recovery and treatment device, which includes a work box and a work chamber located in the work box. A feed port is provided through the upper end wall of the work box, and the front and back wall of the work chamber are rotated. A first rotating shaft is located on the lower side of the feeding port, a first squeeze barrel is fixed on the first rotating shaft, and the front and rear cavity walls of the working cavity are provided with a frontal shaft located on the right side of the first rotating shaft. There are two rotating shafts, and a second squeeze barrel is fixed on the second rotating shaft. The present invention can recycle the used plastic syringes, and the residual gas and water in the used syringes are firstly squeezed by a squeezing device. Squeeze out and compress the plastic syringe to reduce its volume, and then crush the syringe through the crushing device to heat and melt the crushed syringe. During the heating process, it also sterilizes the metal needle. Function, after heating and melting, the molten plastic liquid is separated from the metal needle, and the classification and recovery are completed.

An apparatus for removing a needle from a needle holder, including a grasping unit for selectively grasping the needle; a receiving unit for receiving the needle holder, displaceably disposed relative to the grasping unit; a biasing member biasing the receiving unit in a first direction; and separating means for separating the entire needle from the needle holder. Preferably, the needle is heated to melt, soften, or otherwise weaken a material and/or adhesive connecting the needle with the needle holder. Preferably the heating is electrical heating, including completing an electrical circuit through the needle and passing current through the needle, and/or passing current through a heating element.

A pen needle (101) for use with a drug delivery device (100) includes a hub body (113) having internal threads (216) to receive the drug delivery device (100). A post (121) is connected to the hub body (113). A needle (103) is rigidly fixed to the post (121). The post (121) is separable from the hub body (113) such that the needle (103) is removed with the post (121). The fluid path is not disturbed by such removal because the entire needle (103) is removed with the post (121). Removal of only the post (121) and needle (103) reduces the volume of waste required for disposal, thereby increasing the effective capacity of a sharps container.
