摘要： The present invention safety device is a one-piece needle assembly that has a base and a housing pivotally connected to the base. The base has a distal portion to which a needle is fitted. At the base there is formed longitudinally along its distal portion a catch mechanism that may be in the form of an anchor projection. At the back wall of the housing there is extended another catch mechanism that may be configured in the form of two clasping fingers. Also providing in the housing is an integral hook. As the housing and the base are pivoted relative to each other, and as the needle makes contact with the hook, the respective catch mechanisms at the base and the housing also make contact with each other, resulting in the coupling of the catch mechanisms and the coupling of the needle to the hook. As a result, the catch mechanisms are interlocked and the needle is fixedly retained by the hook within the housing. The catch mechanisms may also be configured as a hook and a latch in the form of a rib with an opening whereto the hook is fixedly coupled. The catch mechanisms may further be configured as respective interlockable pairs of loops and bosses. The gauge of the needle may be determined by the color of both the base and the housing, which are molded as a unitary single unit.

摘要： The present invention relates to a safety device (100) for preventing needlestick injury with a needle (20), comprising: a protective cap (130) and a shield (120) capable of pivoting from a storage position where it is interlocked with the protective cap (130), a retracted position where it gives access to the needle (20) and a safety position where it covers the needle (20), wherein a cam surface (127) of the shield and an engaging peg (137) of the protective cap are arranged so that, when the safety device (100) is mounted around the tip (14) of a medical device (10), removing the protective cap (130) from the tip (14) by a distal movement displaces the shield (120) from the storage position to the retracted position. Furthermore, the present invention relates to a medical device (10) comprising a tip (14) provided with a needle (20) comprising a needle point (22), wherein the medical device (10) further comprises a safety device (100).

摘要： A needle assembly includes a needle and a needle shield device. The needle shield device includes an inner shield connectable to at least one a base and a fluid connector connectable to the base, and an outer shield fixedly connected to the opposing end the needle and displaceable relative to the inner shield between a first position, in which the sharpened end of the needle is exposed outside the inner shield, and a second position, in which the sharpened end of the needle is shielded by the inner shield. Interaction between portions of the inner and outer shields during or after proximal displacement of the outer shield from the first position to the second position automatically releases or permits release of the inner shield from connection to the at least one of the base and the fluid connector.

摘要： A safety syringe is provided with a barrel including a casing tube and a hollow, cylindrical tip; a needle assembly releasably secured to the tip; a pivot assembly releasably secured to the barrel; and a locking cover assembly pivotably secured to the pivot assembly. In inoperative position, the locking cover assembly is distal the needle assembly which is exposed. After dispensing, a pivotal movement of the locking cover assembly toward the needle assembly is configured to cover and lock the needle. This can prevent the needle from accidentally pricking a medical employee to contaminate the medical employee with microorganisms or blood on the needle. Further, this can prevent the safety syringe from being used for a second time. Thus, the safety syringe is ready for disposal.

摘要： A medical device for use with a fluid transfer device includes a hub having an open proximal end with a frusto-conically-shaped cavity therein, a distal end and a passageway therethrough. The cavity is part of the passageway. A release element in the passageway of the hub is positioned to block fluid-tight engagement of the frusto-conically-shaped tip with the cavity of the hub. Structure is provided to release at least part of the release element, upon application of a proximally directed force on the hub, to allow the abrupt fluid-tight engagement of the tip and the cavity in the hub.

摘要： An intradermal injection assembly for injecting a medicament into skin could form an intradermal needle with an adapter, an intradermal syringe with an adapter or an adapter for a merger with a syringe with a cannula. The intradermal adapter in these devices has a body having a longitudinal axis, a central portion having a cannula channel and a distal protrusion extending generally parallel to the longitudinal axis. The distal protrusion of the adapter has a first skin contacting surface extending generally parallel to the longitudinal axis. At least a portion of the distal protrusion is generally transparent such that the portion of the cannula that extends distally relative to a demarcation plane can be viewed through the distal protrusion during insertion of the cannula into a patient's skin.
