 7/17/17 - Patent Issued for Needle Safety Device (USPTO 9694141)

By a News Reporter-Staff News Editor at Journal of Engineering Sanofi-Aventis Deutschland GMBH (Frankfurt am Main, DE) has been issued patent number 9694141, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Slemmen, John (Merseyside, GB); Ward, Chris (Prestatyn, GB).

This patent was filed on October 4, 2012 and was published online on July 4, 2017.

From the background information supplied by the inventors, news correspondents obtained the following quote: "Medicament delivery devices (e.g., pen injectors, syringes, auto-injectors, etc.) that contain a selected dosage of a medicament are well known devices for administering the medicament to a patient. Safety devices for covering a needle of the delivery device before and after use are also well known. Typically, a needle shield of the safety device is either manually moved or automatically to surround the medical needle. Various attempts have been made to develop an optimally sized and functioning safety device. However, there remains a need for an optimal safety needle assembly."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "In an exemplary embodiment, a needle safety device comprises a needle hub including a plurality of resilient arms having detents, a needle having a distal tip, and a needle shield telescopically coupled to the needle hub. The needle shield includes a plurality of axial slots adapted to engage the detents on the resilient arms and the detents are axially movable in the slots. The needle shield includes a plurality of grooves separated from the slots by separation walls and the grooves are adapted to engage the detents. When the needle shield is in a first position relative to the needle hub, the needle shield covers the distal tip of the needle and the detents are engaged in the slots. When the needle shield is in a second position relative to the needle hub, the distal tip of the needle protrudes through an aperture in the needle shield and the detents are engaged in the slots. When the needle shield is in a third position relative to the needle hub, the needle shield covers the distal tip of the needle and the detents are engaged in the grooves. In the third position, the detents are adapted to abut the separation walls and prevent proximal movement of the needle shield relative to the needle hub.

"In an exemplary embodiment, the needle hub includes recesses adapted to receive the detents when the arms deflect. The detents include proximal ramped surfaces, and the separation walls have distal ramped surfaces adapted to engage the proximal ramped surfaces of the detents. Engagement of the distal ramped surfaces of the separation walls and the proximal ramped surfaces of the detents causes the arms to deflect radially.

"In an exemplary embodiment, the separation walls have proximal abutment surfaces adapted to abut the detents in the third position.

"In an exemplary embodiment, the needle safety device further comprises a spring biasing the needle shield relative to the needle hub toward the first and third positions.

"In an exemplary embodiment, the needle safety device further comprises a collar coupled to the needle hub by breakable webs. The needle shield includes a proximal end portion adapted to engage the webs. When the needle shield is moving from the first position to the second position, the proximal end portion breaks the webs. The proximal end portion includes a latch to engage the collar.

"Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description."
