Patent number: 10279108Abstract: The safety needle assembly comprises a housing including a proximal end and a distal end and defining an interior space. A barrel is rotatably received within the interior space of the housing. A needle hub is received within the proximal end of the housing. A needle, including a sharp distal tip, extends distally from the needle hub, through the barrel, and through the distal end of the housing. A safety shield defining a lumen is received within the interior space of the housing. The safety shield extends distally from the housing through the distal end of the housing. The needle extends through the lumen of the safety shield with the sharp distal tip exposed from the safety shield. A biasing member is received within the barrel and extends between the needle hub and the safety shield.Type: GrantFiled: February 6, 2015Date of Patent: May 7, 2019Assignee: B.

Patent number: 10173002Abstract: Needle devices are described. The needle devices can have a catheter hub, a needle hub, a housing located between the catheter hub and the needle hub. The housing can have an engagement mechanism to removably attach the housing to the catheter hub. The housing can further include a release element to release the engagement mechanism from the catheter hub to disengage the housing from the catheter hub. A flow regulator can be positioned inside the catheter hub. The flow regulator can include a stem and a sleeve.Type: GrantFiled: June 8, 2015Date of Patent: January 8, 2019Assignee: B.

Patent number: 9986943Abstract: Blood collection assemblies with safety features are disclosed. The assemblies have a housing for receiving a vacutainer, which has a septum that penetrates a sharp needle tip. The disclosed assemblies further have a shield for covering the other end of the needle following use to prevent accidental contact with the distal needle tip. The shield is spring loaded so that the spring force moves the shield over the needle. The shield can be secured or held in an initial position and allowed to move to cover the needle upon actuation or activation of an activator unit.Type: GrantFiled: June 20, 2014Date of Patent: June 5, 2018Assignee: B. Braun Melsungen AGInventors: Mohd Zairizal Bin Zakaria, Hwa Loon Chan, Teng Sun Teoh, Ai-Mei Tan

Publication number: 20170202498Abstract: A safety needle blood sampling device (100) is provided with a needle (108) having a multi-sampling Luer adaptor (MSLA) mounted over an end thereof. A housing (110) sized and shaped to receive a blood sampling vial is provided so that when a vacutainer is inserted, the MSLA is compressed to puncture the septum with one of the ends of the needle. A protective shield (104) is provided to cover the needle. A helical spring (106) is provided to move the protective shield over the needle in a used position. An activator (112) is further provided that is sized and shaped to activate the shield upon insertion of the vacutainer.Type: ApplicationFiled: May 27, 2015Publication date: July 20, 2017Applicant: B.

Publication number: 20160354580Abstract: A catheter assembly with a catheter, an outer casing positioned over the proximal end and at least part of the hub body of the catheter hub. The outer casing being pliable and has an interior cavity and a septum at a proximal end thereof. A needle hub removably coupled to a proximal end of the catheter hub with the outer casing wedged between the catheter hub and the needle hub. The needle hub has a proximal interior cavity and a shroud with a distal opening. A needle projects distally from the needle hub through the septum of the outer casing and has a needle tip extending out a distal opening of a catheter tube in a ready to use position.Type: ApplicationFiled: June 1, 2016Publication date: December 8, 2016Inventors: Hui Kuun Teoh, Mohd Zairizal Bin Zakaria, Aik Aun Tan, Chee Mun Phang, Mohamad Yasin Bin Abdulla

Publication number: 20160310704Abstract: Needle devices are disclosed in which a needle having a wall defining a needle lumen has a notch (120) formed through the wall. A transparent or semi-opaque window cover (130) made from a biocompatible material is provided over the notch. Blood flow through the needle lumen can be viewed through the notch with the window cover. The needle with the notch and window cover may be used with a variety of needle applications, including as catheter assemblies, indwelling assemblies, and most if not all over-the-needle type devices.Type: ApplicationFiled: December 3, 2014Publication date: October 27, 2016Applicant: B.
