The over-wrap bag maintains the sterility of the enclosed end of the connector. The other end of the connector is typically attached to a piece of tubing or conduit in communication with another larger bag, which has been rendered sterile collectively with the connector. Sterile fluids pumped into the bag, either though the connector itself, or through some other opening in the larger bag, will not be contaminated.

Abstract: A needle safety and protection device that automatically caps the used tip of a needle the instant the needle is withdrawn from the patient to protect the user against infection risks. A spiral type cut safety shield remains relaxed until the device comes in contact with the patient's skin. The safety shield attaches to the patent's skin through an adhesive component creating a tensile force once the needle is withdrawn, extending the safety disk out of its relaxed position. Under tension, the safety disk creates a cone around the needle, forming a protective shield for the needle, without any assistance by the user. The tip of the needle then engages a portion of the shield, which prevents the tip from being re-inserted into the skin of the patient or the user of the needle.

Abstract: A needle assembly includes an elongate square cross-sectioned needle mount (10), a needle (12), and a sheath (14) mounted on the needle mount (10) for reciprocal axial movement between a forward position whereat the sheath (14) covers the needle (12) and a rearward position whereat the needle (12) is exposed. The sheath (14) is bifurcated at its rearward end to define opposed resilient members (30) which engage a portion (18) situated rearwardly of first ramps (24) when the sheath (14) is in a rearward injecting position. Subsequent to injection occurring, the sheath (14) is axially rotated through 90 degrees relative to the needle mount (10) to disengage the resilient members (30) from the ramps (24). The sheath (14) then automatically slides under the action of a compression spring to the forward position so that the resilient members (30) lockingly engage second ramps (26), rendering the needle (12) safe.

Abstract: A needle device, possibly in the form of a butterfly or IV needle, has a housing with an orthogonal passage to the bore of the housing. A key that has a non-uniform opening with spaces defined by the opposing inner walls of its two extending legs is inserted into the passage. By positioning the key at different placement locations relative to the passage so that the different dimensioned spaces of the opening become aligned with the bore of the housing, the needle assembly can be selectively retained at at least a first position whereby the needle is extended out of the housing, and a second position whereby the needle is permanently retracted within the housing after use.

Abstract: An infusion device has a body, flexible wings and a needle projecting generally at right angles from one end of the body. A guard is pivoted to the one end of the body. On one side, the guard has a channel so that the guard overlies the body in a first position thereof during application of the needle to the patient. The guard is pivotable through about 180° to a position generally parallel to the body and on a side of the needle remote from the body. As the needle is withdrawn from the patient, the guard is pivoted about 90° further to receive the needle between one or more flexible contoured members along the opposite side of the guard. The needle is thus captured and encapsulated within the guard, with audible confirmation, the members precluding the guard from pivoting away from the needle.

Abstract: A needle and hub assembly for an automatic injector and a method for making the needle and hub assembly. The needle and hub assembly comprises a cap or skirt, a forward surface of which is interposed between and reinforced by first and second engaged hub portions. A needle is received in a contiguous channel formed in the two hub portions. The method for making the assembly comprises molding the first hub portion, placing the cap over the first hub portion, inserting the needle into a channel in the first hub portion, and then overmolding or otherwise forming the second hub portion on the exterior of the cap such that it is engaged with the first hub portion. An assembly created by this “two-shot” process can be used to seal a relatively large opening, and supports the needle more effectively than a conventional assembly.

Abstract: In a medical needle device having a shield for reduction of needlestick injuries, a protrusion is formed on an outer peripheral surface of a hub to which a needle is mounted, a height of the protrusion being set so that the protrusion protrudes beyond an inner diameter of a shield tube, and a gate groove is formed at an inner surface of the shield tube to extend from a front end to the vicinity of a rear end, dimensions of the gate groove being such that the protrusion can fit in a front end portion of the gate groove. In a state where the protrusion is exposed from the front end of the shield tube, the hub can rotate with respect to the shield tube. At a rotational position of the protrusion at which it does not face a front end of the gate groove, a position of the hub is limited so as not to move toward a rear end side of the shield tube due to engagement of the protrusion with a front end face of the shield tube.

Abstract: A medical needle device includes a winged shield (4) having a substantially cylindrical shaped shield cylinder (4a) and wings (5, 6) connected to the front end side thereof, a needle base (2) inserted in the shield cylinder (4a), and a needle (1).
