A needle stick prevention device (10, 110) includes a needle shield (20, 120) for selectively covering a distal end of a needle (41, 141). A needle hub (40, 140) is movably received within the needle shield (20, 120). The needle hub (40, 140) includes a proximal end (42, 142), a distal end (46, 146), a needle (41, 141) fixedly connected to the distal end of the needle hub (40, 140), and a plurality of ribs (54) or a cylinder (150) disposed between the proximal and distal ends. An actuation button movably received in a transverse opening of the needle shield (20, 120) to engage the needle shield (20, 120), the needle hub (40, 140) and a medical device. A spring (58, 158) is disposed between the needle hub (40, 140) and actuation member to automatically retract the needle (41, 141) into the needle shield (20, 120).

A needle set includes a needle guard and a winged needle. The needle guard has upper and lower jaws, each of the upper and lower jaws defining a channel and coming together at a hinge. The upper and lower jaws are separated by slots in sides of the needle guard, which slots divide the sides into upper and lower side walls, respectively. The winged needle can be inserted between the upper and lower jaws, with wings of the winged needle passing through the slots. The hinge has an opening and a tube connected to the winged needle passes through the opening.

An injector may include a container having a wall with an interior surface and a seal assembly with an interior surface, the interior surfaces of the wall and the seal assembly defining a closed sterile reservoir filled with a drug product. The injector may also include a fluid delivery system comprising a clean, unsheathed, rigid container needle having a point disposed only partially through the seal assembly in a storage state, and disposed through the interior surface of the seal assembly into the sterile reservoir in a delivery state. Further, the injection may include an actuator that is adapted to move the container needle from the storage state to the delivery state.

A valve assembly for a drug delivery device includes a valve housing, a cannula having a first end and a second end positioned opposite the first end, a valve boot connected to the valve housing and defining an interior space, a valve sleeve defining a cannula space, with the valve sleeve configured to move from a pre-use position where the first end of the cannula is received within the cannula space to a use position where the first end of the cannula extends outside of the valve sleeve and the cannula space, and a piercing member having a body with a piercing tip. The body of the piercing member has a first end and a second end positioned opposite the first end, with the piercing member engaged with the valve sleeve.

A peripheral intravenous catheter assembly may include a low-drag septum. The septum may include a body having a distal end and a proximal end, which may be sealed. The septum may include a slot disposed within an outer surface of the body and oriented along a longitudinal axis of the body. The slot may include a distal end spaced apart from the distal end of the body, and a proximal end spaced apart from the proximal end of the body. An introducer needle may extend through the slot.

A safety needle assembly includes a housing and a cannula hub connected within a side wall of the housing, a needle connected to the cannula and extending from the cannula hub outward from a proximal end of the housing, and a spring connected with the housing. The assembly includes a barrel connected with the spring and at least partially contained within the housing to least partially cover the cannula hub. The barrel is configured for moving, sliding, traveling, activating, relocating, or transitioning from a first mode in which the barrel is securely retracted and locked at least partially within the housing and the needle extends through an aperture of the barrel and the proximal end of the housing, to a second mode in which the barrel extends from the proximal end and beyond the needle.

A medical infusion device including a chamber characterized by an upper body joined to a lower body via a reversibly collapsible sidewall. The upper body has a first channel fluidly coupled to a needle and a second channel fluidly coupled to an interior of the chamber. The chamber transitions from a collapsed state to the expanded state to retract the needle by introducing fluid into the interior of the chamber through the second channel.

A method of making a needle guard includes providing a mold having a portion defining a volume, the volume being a hollow cylinder with non-uniform walls with a pair of slots therein, the slots being open at one end and closed at the other end, the pair of slots having a major portion of constant width. The walls are thicker at the other end than at the one end. The method includes filling the volume with polymer and releasing a molded part from said mold and cooling a molded part resulting from the filling and releasing such that temperature that the widths of the pair of slots is non-uniform after cooling. The needle guard has upper and lower jaws defining a channel and coming together at a hinge. A winged needle can be inserted between the jaws, with the wings of the winged needle passing through slots between the jaws.

A peripheral intravenous catheter assembly may include a low-drag septum. The septum may include a body having a distal end and a proximal end, which may be sealed. The septum may include a slot disposed within an outer surface of the body and oriented along a longitudinal axis of the body. The slot may include a distal end spaced apart from the distal end of the body, and a proximal end spaced apart from the proximal end of the body. An introducer needle may extend through the slot.

An example agent administration device may comprise a housing. The device may further comprise a sharp assembly including a delivery sharp. The sharp assembly may be reciprocally displaceable along a guide channel of the housing. The device may further comprise an access port in fluid communication with the delivery sharp. The device may further comprise an actuation assembly configured drive the sharp assembly, via urging of a single bias member, from a storage state in which the delivery sharp is within the housing, through a first extended position in which the delivery sharp extends a maximum distance from the housing and to a partially retracted position in which the delivery sharp extends a lesser distance from the housing.
