Publication number: 20210052859Abstract: A safety needle assembly having a first hub attached to a flexible tube and a second hub attached to a needle projecting through the flexible tube. A needle guard is positioned in an interior cavity of the first hub. The needle guard has a proximal wall having an opening and two arms each with an end and wherein the two ends spaced from and biased toward the needle in a ready position. In a particular example, a support is located inside the cavity of the first hub and wherein the two ends of the two arms on the needle guard rest on the support in the ready position.Type: ApplicationFiled: November 9, 2020Publication date: February 25, 2021Applicant: B.

Patent number: 9919136Abstract: A catheter assembly includes a catheter hub having an elastomeric septum that divides the catheter hub into a distal chamber and a proximal chamber. The septum also includes at least one slit that is closed and sealed when the septum is in an at-rest state. A septum activator is proximal the septum. When an external force pushes the activator against the septum, the activator deforms the septum so as to break the seal and create a flow path through the septum. A portion of the septum activator can be collapsible when subjected to the outside force. When the outside force is removed, the collapsible portion springs back to its at-rest shape, helping to pull the activator out of deforming engagement with the septum so that the septum can reseal. The activator can also be spring-biased away from engagement with the septum so that when the outside force is removed, the spring urges the activator out of engagement with the septum. With the activator removed, the septum slit can reseal.Type: GrantFiled: November 21, 2014Date of Patent: March 20, 2018Assignee: B.

Patent number: 9717887Abstract: A catheter assembly includes a catheter hub and an introducer needle. The introducer needle extends through the catheter hub and through a catheter tube so as to assist placement of the catheter tube into a patient's blood vessel. Blood flashback into the catheter tube and/or catheter hub can indicate when the catheter tube is properly positioned within the blood vessel. After proper catheter tube placement is confirmed through blood flashback, the introducer needle is withdrawn. A septum blocks flashback blood from flowing proximally out of the catheter hub. One or more air vents enable air within the hub to vent when flashback blood enters the catheter hub. A porous hydrophobic material covers the one or more air vents. The hydrophobic material allows the air to flow therethrough and through the vents, but repels blood, blocking blood from flowing through the air vents.Type: GrantFiled: November 21, 2014Date of Patent: August 1, 2017Assignee: B.

Publication number: 20160361490Abstract: Safety needle assemblies that include a needle having a sharp distal tip and a needle tip cover mounted on the needle are disclosed. The needle tip cover includes a first portion having a channel receiving the needle and a second portion attached to the first portion. The second portion has a proximal wall, an opening in the proximal wall receiving the needle, a sidewall extending distally from the proximal wall, first and second spring arms extending transversely from opposite edges of the sidewall, and a third spring arm extending distally from the sidewall. The first spring arm and the second spring arm extend at least partially around the first portion. The third spring arm includes a flange extending radially inward and configured to bear against the needle to deflect the third spring arm radially outward against a spring restoring force in a ready to use position.Type: ApplicationFiled: June 12, 2015Publication date: December 15, 2016Applicant: B.

Publication number: 20160008581Abstract: Safety needle assemblies, needle guards, and related methods are disclosed. The guards may be used on different needle applications to cover the tips of the needles. Exemplary needle guards are disclosed in which a curved bore profile is provided so that when the crimp or bulge on the needle retracts into the curved bore profile, the axial movement of the needle causes the needle guard to undergo a rotary movement.Type: ApplicationFiled: July 7, 2015Publication date: January 14, 2016Applicant: B.

Patent number: 6155846Abstract: An electrical contactor assembly (10) has a conductive body (11) with an external thread (12). An electrical contact (14) is electrically coupled via a conductive spring (25) to body (11). A housing (16) is attached to body (11) and has an opening (27) to allow protrusion of an elongate cylindrical conductor (24) of electrical contact (14) having a contact surface (15). An abutment (26) of elongate cylindrical conductor (24) abuts housing (16) for captive location therein and to retain electrical contact (14) in a bore (31) in body (11) against the biasing influence of spring (25). External thread (12) is self-tapping and can be self-drilling.Type: GrantFiled: January 3, 2000Date of Patent: December 5, 2000Assignee: Motorola, Inc.Inventors: Pit Yeow Yeoh, Wei Wei Ong, Chin Chin Ooi, Soo Yong Tan
