Patent number: 8251956Abstract: A securement device holds a medical article such as a catheter hub in position upon the body of a patient and at least inhibits longitudinal movement of the medical article. The securement device includes a retainer and at least one anchor pad. The retainer includes a metallic insert having barbs or teeth extending into a central channel. The metallic barbs or teeth dig into the retained catheter hub. The metal insert springs open as the hub is inserted in to the device and retains the hub by virtue of its metallic barbs.Type: GrantFiled: October 18, 2007Date of Patent: August 28, 2012Assignee: Venetec International, Inc.Inventors: Steven Bierman, Richard Pluth

Patent number: 7955307Abstract: A method of securing a medical article to the body of a patient is disclosed in which an anchoring device comprising an anchor and a retainer is used. The retainer is attached to an upper surface of the anchor and comprises a base, a cover and a post. The base is disposed on the upper surface of the anchor and the cover is connected to the base so as to move between an open and a closed position. When the cover is in the closed position, it lies above at least part of the base. The post is attached movably to either the base or the cover and is arranged so as to lie at least partially between the cover and the base when the cover is in the closed position. When securing a medical article, the cover is placed in the open position and the medical article placed onto the retainer. The cover may then be closed over the medical article and the anchoring device attached to the patient.Type: GrantFiled: August 10, 2007Date of Patent: June 7, 2011Assignee: Venetec International, Inc.Inventors: Steven Bierman, Wayne T.

Publication number: 20100179481Abstract: A securement device (10) for securing a medical line to a neonate includes first and second anchors (20a), (20b) disposed in opposing relationship to each other. Each anchor (20) comprises an anchor pad (22), a retainer (26), and a connector (24) connecting the anchor pad (22) and retainer (26). The connectors (24) extend in a direction substantially normal to the anchor pads (22) and grip the medical line from opposing directions. The device (10) is particularly adapted for use in connection with neonates and provides a small securement surface to fit onto the small body locations of a neonate. The device (10) is also particularly adapted for applications in which the medical line enters the body in a direction generally normal to the surface of the body, such as umbilical, nasogastric, or endotracheal applications.Type: ApplicationFiled: September 10, 2007Publication date: July 15, 2010Applicant: Venetec International, Inc.Inventors: Steven Bierman, Richard Pluth

Publication number: 20090076457Abstract: An anchoring system for an elongated medical article comprises an anchor pad and a retainer mounted upon the anchor pad. The retainer includes a base, a cover, and a compressible member including a receptacle into which the medical article to be retained is placed. When the cover is closed, the medical article is secured within the receptacle by the pressure of the compressible member and the cover upon the medical article. One or more biasing members act upon the compressible member to increase the frictional forces acting on the retained section of the medical article. The receptacle may form a channel that follows a curved path through the retainer. The retainer may also include guide extensions to support the medical article along a transverse bend toward the skin of the patient.Type: ApplicationFiled: August 10, 2007Publication date: March 19, 2009Applicant: Venetec International, Inc.Inventors: Steven Bierman, Richard Pluth, Wayne Mitchell

Publication number: 20080077118Abstract: A releasable medical device connector comprises a connector fitting with a spin nut which connects to an adaptor. The connector fitting has at least one radially extending member with a variable radius cross section. The spin nut is disposed upon the connector fitting proximal of the radially extending member and is both axially slidable and rotatable upon the elongated body of the connector fitting. A screw thread within a proximal portion of the spin nut is used to secure the tapering portion of the connector fitting to an external thread disposed upon the adaptor. To release the connector, the spin nut is unscrewed from the adaptor and slid so that a distal receptacle of the spin nut engages the radially extending member of the connector fitting. With the spin nut and connector fitting engaged, the medical line can be released from the adaptor by twisting and pulling upon the spin nut.Type: ApplicationFiled: November 30, 2007Publication date: March 27, 2008Applicant: Venetec International, Inc.Inventor: Steven Bierman
