A medical device connector includes a fluid transfer tip including a tapered surface for creating a friction fitting between the fluid transfer tip and a hub. A separable collar includes a first and second arcuate segments. The second segment includes an engagement feature for engaging with a corresponding engagement feature of a hub. A moveable disconnection member is arranged such that movement of the disconnection member moves the second segment of the separable collar from a first closed collar configuration position, to a second position, corresponding to an open collar configuration, in which the second segment is moved relative to the fluid transfer tip and the first segment, so as to allow disengagement of the engagement feature from the corresponding engagement feature. Movement of the disconnection member also releases the friction fitting between the fluid transfer tip and the hub.

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 needle tip assembly for a pre-loaded syringe or a pen needle injection device, including a needle with a first puncturing end projecting from a front side of a needle support and a second puncturing end projecting from a rear side of the needle support. A body sized to receive therein the needle support and the needle. The body including a front portion, a rear portion, and an overall axial length that is greater than an axial length of the needle. Prior to the needle tip assembly being in an installed condition on the pre-loaded syringe or pen needle injection device, the front portion covers the first puncturing end and the rear portion covers the second puncturing end. Prior to removal from the pre-loaded syringe or pen needle injection device, the body is at least axially movable to a position where the front portion covers the first puncturing end.

The present disclosure relates to an apparatus and a method. The apparatus comprises a body part and a cover part, wherein the body part and the cover part are configured to at least partially form a fluid channel between a surface of the body part and a surface of the cover part. The surfaces of the body part and the cover part may be facing surfaces. The method comprises manufacturing the apparatus according to the present disclosure.

An injection system includes a body member having a body connection member at a distal end thereof. The system also includes a needle hub assembly coupled to the distal end of the injection system body. The needle hub assembly includes a needle hub coupled to the body connection member, a needle coupled to the needle hub, and a spacer removably coupled to the needle hub. The spacer reduces an exposed length of the needle.

The present disclosure relates to a stopper adapted for use in a drug delivery device. In one implementation, the stopper includes a rigid casing having a shape adapted to fit within a barrel of the drug delivery device; electronics disposed and sealed within the rigid casing; and an elastomeric seal disposed around at least a dispensing end of the rigid casing and a side of the rigid casing. The electronics include a power source and at least one of a transducer or a sensor coupled to the power source. The elastomeric seal comprises a single continuous material.

A pen needle assembly includes an adapter (32, 122, 190, 254, 312) and a needle hub (134, 124, 192, 256, 314) coupled to the adapter. The needle hub is removable from the adapter. The adapter has a distal end for coupling with a pen needle delivery device and a distal end with at least one coupling member for coupling with the needle hub. The needle hub is a distal face forming a skin contact surface and a cannula extending from the distal face. The proximal end of the needle hub includes a coupling member for removably coupling with the coupling member of the adapter.

A valved needle assembly including a needle hub provided to a proximal end side of a hollow needle, and a valve member incorporated therein for blocking communication with the hollow needle. A protrusion protrudes from a distal end side toward a proximal end side inside the needle hub and the valve member blocks the proximal end side of the protrusion inside the needle hub. A central valve part of the valve member having a slit moves toward the protrusion such that the slit is opened and placed in communication by the protrusion. The central valve part includes a distal end tubular part and a proximal end tubular part extending from its outer circumferential portion toward the distal end side and the proximal end side respectively.

A needle and syringe system that provides ultra-low dosage waste and automatic needlestick protection. A syringe assembly is provided that contains a barrel and a plunger. A tubular spacer is disposed in the barrel. A needle head assembly is provided that includes a collar and a needle. A safety slide is positioned between the needle and the collar. The safety slide has a sheathing tube that surrounds part of the needle. The safety slide can move relative the needle. In a first position, the sheathing tube does not extend beyond the sharpened end of the needle. In a second position, the sheathing tube extends beyond the sharpened end of the needle. When advanced, the plunger head moves the tubular spacer. The tubular spacer passes over the base of the needle and presses against the safety slide. The safety slide is moved from the first position to the second position.

A smart drug injection device is disclosed, comprising a main body, a circuit board, a display, a syringe and a transmission mechanism; the main body comprises an accommodating space and a power button; the circuit board comprises a control unit and a storage unit; the transmission mechanism comprises a motor, a screw rod, a propelling block and a movable clamp, with the control unit electrically connected to the storage unit, the power button, the motor and the display, the motor connected to the screw rod, the propelling block movably arranged on the screw rod, the movable clamp disposed at one end of the propelling block and movable between two positions; the syringe is on one side of the main body and comprises a cylinder and a needle holder, one end of the cylinder has a needle and the other end is assembled with the needle holder.
