Abstract: A safety needle device includes a housing, a Huber needle, a cap and a sheath. The Huber needle has a first needle leg disposed in the housing and a second needle leg extending perpendicularly of the first needle leg. The cap is disposed over the second needle leg and is movable relative thereto from a first position with the second needle leg extending through the cap to a second position with a tip of the needle disposed in sealed relation in the cap. The sheath is concentrically disposed on and about the needle in a collapsed state, and secured to and between the housing and the cap. The sheath is extendable from the collapsed state to an extended state in response to movement of the cap from the first position to the second position.

Abstract: A male adaptor is provided with a nose for penetrating into a housing of the female connector. A septum is disposed over the nose of the male adaptor to maintain a seal with the female connector during coupling and uncoupling. Upon coupling, the septum dilates to allow the nose to pass through. The female connector may have a septum that also dilates to allow penetration of the nose of the male adaptor. Alternatively, the septum of the female connector may be retractable under the force of the nose of the male adaptor.

Abstract: The needle of a syringe, wire guide, biopsy needle, Huber needle and the like is drawn into a protective cap and sheath arrangement after use for disposal purposes. The cap is tethered to a housing in which the needle is mounted by the sheath. The sheath is made of a film material that has a high tensile strength and a low percent of elongation, such as polyester. The sheath is initially mounted about the needle in a collapsed accordion-like condition between the cap and housing. When the cap is moved along the needle, the sheath is played out over the needle. The cap houses a spring clip to snap over the bore through which the needle is retracted to prevent re-emergence of the needle. The flexible nature of the sheath allows the sheath to pass about the two legs of the Huber needle.

Abstract: The needle guard is attached to the needle hub by a polyester film strip and the needle passes through longitudinally spaced apart apertures in the strip. The film strip is housed in the needle guard in corrugated manner. When the needle guard is pulled over the needle, the needle moves into the housing of the needle guard and into abutment with the housing while the strip is stretched between the hub and the housing to retain the housing connected to the hub under a biasing force.

Abstract: The needle guard employs a spring clip that has a pair of apertured locks through which the needle passes. The aperture in the foremost lock is defined by cutouts that deflect inwardly upon withdrawal of the needle in order to block a return passage of the needle. The end of the needle is enlarged to abut against the rearmost lock and to further prevent a return passage through the foremost lock. The enlarged end of the needle is trapped between the two locks after being drawn into the needle guard.

Abstract: The positive flow needleless connector has a cannula slideably mounted within a tubular housing. A sleeve-like septum seals the cannula from an outside environment while also sealing an internal chamber of the cannula from a flow path in a male luer housing. Movement of the cannula from an extended position to a retracted position against the force of a spring exposes a second inlet of the cannula to the flow path of the male luer housing to permit flow therebetween. During disconnect, the inlet from the cannula is sealed prior to the cannula returning the extended position. This allows fluid to move from a reservoir between the cannula and septum to move into the passage of the male luer housing.

Abstract: A male adaptor is provided with a nose for penetrating into a housing of the female connector. A septum is disposed over the nose of the male adaptor to maintain a seal with the female connector during coupling and uncoupling. Upon coupling, the septum dilates to allow the nose to pass through. The female connector may have a septum that also dilates to allow penetration of the nose of the male adaptor. Alternatively, the septum of the female connector may be retractable under the force of the nose of the male adaptor.

Abstract: The safety needle employs a manually operable actuator that can be depressed into a housing in order to release a spring-biased slider that carries a hollow needle. Upon release, the slider moves into a position to retract the needle over a blunt cannula so that the blunt cannula protects against cutting by the needle. An actuator guard may also be employed to prevent inadvertent actuation of the actuator.

Abstract: A plastic needle guard is mounted on a hub in which a needle is secured. In order to cover the end of the needle, the needle guard is slid manually off the hub and over the end of the needle to position the needle end within the guard. A washer that is loosely mounted within the guard and through which the needle passes drops off the end of the needle to block any return movement of the needle out of the guard. Other embodiments use lock-type washers to prevent a return movement of the needle.

Abstract: The over-the-needle catheter is provided with a septum seal within the hub of the catheter. The introducer needle passes through the septum seal and into the catheter. Upon removal of the introducer needle, the septum seal reseals so that blood is prevented from flowing from the patient out of the hub. A male luer adaptor is used to form a connection, for example, to an IV bag by pushing the seal onto a tube secured within the hub and communicating with the catheter or, in another embodiment, by pushing a piercing ring through a slit in the septum seal to form a permanent lumen.

Abstract: The suction tube set employs a compressed cellulosic sponge mass as a fluid absorber in the suction line for absorbing an amount of fluid, for example 1.5 cc, without any significant increase in resistance to air flow. The compressed sponge mass is secured in place within a tubular housing of the suction tube set with a gap formed between each end of the sponge mass and an end cap of the housing to avoid blockage of air flow.
