International Classification:

A61M 5/32

US Classification:

604198

Abstract:

A safety pen needle assembly is provided herein which includes a hub and a needle fixed to the hub. Further, a first shield is provided, along with a second shield which has a biasing element disposed to urge the second shield proximally towards a proximal end of the needle. The assembly further includes a releasable retaining assembly for releasably retaining the second shield in an initial position against the force of the biasing element. A predetermined extent of movement of the first shield causes the retaining assembly to release the second shield, and, wherein, with the second shield being released, the second shield is urged proximally by the biasing element to a second position where the second shield covers the proximal end of the needle. Advantageously, with the subject invention, an assembly is provided which allows for passive activation of a shield on a non-patient end of a pen needle assembly by a patient-end shield.

International Classification:

A61M 5/315

US Classification:

604220

Abstract:

A plunger rod adapted for attachment with a stopper for use with a syringe barrel is disclosed. The plunger rod includes an elongated member having a front end and a back end, the plunger rod extending along a longitudinal axis. The plunger rod includes at least one deflecting arm associated with the front end of the elongated member. The deflecting arm is capable of deflecting radially inward during insertion of the plunger rod into a stopper, and deflecting outward into contact with an inner surface of the stopper after insertion to lock the plunger rod within the stopper.

International Classification:

A61M 5/315

US Classification:

604506, 604227, 604218

Abstract:

A reduced profile syringe assembly is provided that includes an overall profile that is substantially similar to the profile of the syringe barrel. The syringe assembly includes a plunger rod that is significantly disposed within the syringe barrel when filled for use, with the plunger rod adapted to be retracted from the syringe barrel during dispensing of the contents of the syringe barrel.

International Classification:

A61M 5/32

US Classification:

604198

Abstract:

In one aspect, a safety pen needle assembly is provided herein which includes a hub with a needle fixed to the hub, the needle having a distal end, formed for insertion into a patient, and a proximal end. The assembly further includes a shield and a biasing member disposed between the hub and the shield configured to urge the shield distally. A protrusion extends from at least one of the hub and the shield with a channel being formed in at least the other of the hub and the shield. The channel is formed to accommodate the protrusion. The shield is movable from a first position to a second position. In the first position, the shield is spaced from the distal end of the needle such that the distal end of the needle is exposed. In the second position, the shield covers the distal end of the needle. The channel guides the protrusion as the shield moves from the first position to the second position. With this arrangement, a shield may be directed to move in a desired path with stability. In addition, the distal end of the needle may be initially exposed to permit visual confirmation of priming, while allowing the shield to cover a majority of the needle to minimize any needle-related anxiety.

International Classification:

A61M 5/32

US Classification:

604198

Abstract:

A safety pen needle assembly is provided herein which includes a hub; a needle fixed to the hub having a distal end, formed for insertion into a patient, and a proximal end; a shield; a biasing means disposed to urge the shield from a first position to a second position; and, at least one adjustable tab or locking finger on the hub, the tab or finger being adjustable from a first state to a second state. With the tab or finger being in a first state, the tab or finger interferingly engages the shield so as to restrict movement thereof. The tab or finger in the first state retains the shield in its first position with the proximal end of the needle being exposed. With the tab or finger being in the second state, the tab or finger does not interferingly engage with the shield. As such, the shield is permitted to be urged proximally to the second position by the biasing means. In the second position, the shield covers the proximal end of the needle. Advantageously, with the subject invention, a mechanism is provided for shielding a proximal, or non-patient, end of a pen needle, particularly after use.

International Classification:

A61M 5/315

US Classification:

604222

Abstract:

A stopper adapted for attachment with a plunger rod for use within a syringe barrel includes a main body portion defining an open rearward end configured to receive the plunger rod. The main body portion is manufactured from a rigid or semi-rigid polymeric material having an elastic modulus in the range of about 0.01 GPa to about 5 GPa. When fluid pressure is increased inside the syringe barrel during an injection, at least one of the following actions occurs: a) a flexible roof of the main body portion expands in a radial direction toward an inner wall of the syringe barrel; b) a first perimetrical skirt extending around an outer circumference of the main body portion is forced against an inner wall of the syringe barrel; and c) an engagement between the plunger rod and an engagement portion provided along an inner circumference of the main body portion.

US Classification:

604222

Abstract:

A stopper includes a main body portion defining an open rearward end configured to receive the plunger rod, an engagement portion provided along an inner circumference of the main body portion configured to engage at least a top portion of the plunger rod, a closed front end forming a flexible roof, and a first perimetrical skirt extending around an outer circumference of the main body portion toward the closed front end of the main body portion. When fluid pressure is increased inside the syringe barrel during an injection, the flexible roof expands in a radial direction toward an inner wall of the syringe barrel, the first perimetrical skirt is forced against the inner wall of the syringe barrel, and an engagement between the plunger rod and the engagement portion forces the main body portion to expand in the radial direction toward the inner wall of the syringe barrel.
