The present disclosure relates to a body arrangement for a drug delivery device, comprising at least one deployable body part arranged to be moved from a compact state into a deployed state, wherein the body part in the deployed state provides an enlarged grip area compared to the compact state.

Disclosed is a Huber needle assembly that may include an upper body connected to a lower body, the assembly being structured to retain a needle for insertion/extraction of the needle into/from an insertion site. The upper body can statically retain the needle while the lower body may slidably receive the needle. The lower body can further include a catch that engages a tip of the needle and/or misaligns the tip of the needle with a needle aperture of the lower body to place the assembly in a safety-lock position, preventing rebound, needle-stick injury, and/or any type of exposure of the needle tip to an environment outside of the lower body. The assembly can further bias the needle in a direction so as to prevent re-emergence of the needle tip after being withdrawn into the lower body.

A device for delivering a fluid into a biological tissue includes hollow microneedles (10) projecting from a surface (12) of a substrate (14), and a guide element (18) spaced from the substrate. The guide element provides a tissue-contact surface (20) that defines a tissue contact plane oblique to the surface (12) of the substrate (14).

The present invention relates to a needle including: a needle hub having a needle with a distal tip; a ring for protecting the needle in one of a storage condition or end-of-use condition of the needle assembly; a foldable element for moving the protective ring; a biasing element for urging the foldable element from its folded configuration to an unfolded configuration; a retainer for maintaining the biasing element in an intermediate stressed state at least in the storage condition of the needle assembly; and a deactivating element for releasing said retainer at least at the end of the injection step. The invention also relates to an injection device including such a needle assembly and a container.

Syringes and methods of preparing a stabilized hydrogen peroxide solution are described. A method includes filling a portion of a syringe with a hydrogen peroxide solution. The portion of the syringe may contact the hydrogen peroxide solution. The portion may be or include cycloolefin polymer (COP) or cycloolefin copolymer (COC). The method also includes storing the hydrogen peroxide solution in the syringe for a period of time. The hydrogen peroxide solution may be characterized by improved stability after the period of time relative to storing the hydrogen peroxide solution in a glass syringe for the period of time.

An apparatus for use with a syringe to provide a safety syringe, the apparatus comprising: a sheath (100; 300; 500; 700; 900; 1100; 1300) deployable for at least partially covering a needle of the syringe; a sheath actuator (102; 302; 502; 702; 902; 1102; 1302) for deploying the sheath; and a ratioed mechanism (104; 304; 504; 704; 904; 1104; 1304) linking the sheath and the sheath actuator and configured such that a magnitude of movement of the sheath is greater than a magnitude of movement of the sheath actuator during deployment of the sheath.

A shieldable needle device (12) with a needle cannula (28), a hub (44) supporting the needle cannula, and a tip guard (24) axially movable along the needle cannula where, upon transition, the tip guard protectively surrounds the distal end (42) of the needle cannula. The needle device includes a pair of wings (60) extending laterally from opposing sides of the tip guard and connected to the hub. The pair of wings are transitionable between a first position and a second position, wherein transition of the pair of wings advances the tip guard from a proximal position to a shielding distal position. The wings include protrusions (66) which cause the longitudinal axis of the needle cannula to become offset from the opening (52) of the tip guard during advancement of the tip guard preventing the needle cannula from being reinserted through the tip guard after the tip guard has been transitioned to the distal position.

A stab-resistant syringe needle with an elastic protective cap and a stab-resistant syringe are provided, which include the elastic protective cap. After the syringe is used to complete injection, the protective cap can be automatically ejected through simple operations to shield a steel needle, so as to achieve a purpose of preventing stab wounds.

A needle guard assembly having a resilient arm extending from a base situated to slide along the shaft of a needle. In one implementation the needle guard has an elongate containment member that rides with the resilient arm and is co-operable with the resilient arm to effectuate a covering of the entire distal tip of the needle upon the needle being retracted into the needle guard.

A Hypodermic Needle Safety Guard intended for sharps prevention and safer hypodermic needle use during all stages of an injection process. The Safety Guard may include two symmetrically positioned multi-featured arms that include spring tension, multiple hinges and needle locks. These arms may connect a proximal Luer body and a distal alignment tip thereby enabling the guard to open, close and lock on a needle when manual pressure is applied. The Guard position during hypodermic needle use tends to prevent sharps injury by adjusting the exposure of the Needle tip.
