Publication number: 20120054940Abstract: A protective garment comprising a gown and an improved collar mechanism and method of use for securing protective gowns, typically used in health care settings, around the neck of a user without the need to secure with ties, tabs, snaps or other securing devices. The collar mechanism is made pliable when fastened to the garment so as to be deformed without fracture when force is applied but with a sufficient memory when combined with the gown that allows the collar to return to its original position once the force is removed. The collar mechanism may be manufactured efficiently by using a rotary die cutting machine to created nested pairs of pieces of a two-piece embodiment arranged spirally on a stock.Type: ApplicationFiled: November 14, 2011Publication date: March 8, 2012Inventor: Thor R.

Patent number: 7776016Abstract: A safety enclosure which is designed for a hypodermic needle that is located in the shape of an approximate right angle (Huber needle). A safety enclosure has a needle housing within which the Huber needle is mounted. The needle housing is mounted in conjunction with a panel unit. The panel unit is composed of a series of planar panels which are edge connected together defining an enclosed area. The panel unit can be movable from a basically transverse position to an elongated position. When in the transverse position, the panel unit is to be mounted with adhesive tape onto the skin of a patient with the sharp end of the needle being inserted within the body of the patient. When the panel unit is in the elongated position, the needle is withdrawn from the body of the patient and the sharpened end of the needle is covered by the panels thereby preventing undesired needlestick injury to the medical practitioner that is installing and removing the enclosure.Type: GrantFiled: February 26, 2004Date of Patent: August 17, 2010Assignee: C. R. Bard, Inc.Inventors: Thor R. Halseth, John M. Barker

Patent number: 7753887Abstract: A catheter insertion device is provided that includes an insertion needle that is retractable into the device after use to prevent exposure to the contaminated needle. The needle retainer releasably retains the needle in an extended position against the bias of the biasing element. When the catheter is removed from the insertion device, the needle retainer automatically releases the needle, which is propelled rearwardly into the device. A device for inserting a guide wire into a patient is also provided. The device includes an insertion needle that is retractable into the housing of the device after use. A needle retainer releasably retains the needle in an extended position against the bias of the biasing element. After the guide wire is inserted into the patient, the needle retainer allows the needle to be released, so that the needle is retracted into the device.Type: GrantFiled: March 28, 2003Date of Patent: July 13, 2010Assignee: MDC Investment Holdings, Inc.Inventors: Michael J. Botich, John Barker, Thor R. Halseth

Publication number: 20100031419Abstract: A protective garment comprising a gown and an improved collar mechanism and method of use for securing protective gowns, typically used in health care settings, around the neck of a user without the need to secure with ties, tabs, snaps or other securing devices. The collar mechanism is made of a stiff material that is pliable enough to be deformed without fracture when force is applied but with a sufficient memory that allows the collar to return to its original position once the force is removed.Type: ApplicationFiled: October 15, 2009Publication date: February 11, 2010Inventor: Thor R.

Patent number: 7527607Abstract: A safety needle-bearing medical advice (10) is provided. Specifically, a safety device for injecting medicinal fluid into a patient is provided. The device comprises a hollow housing (20), a needle assembly (40) and a plunger (30). The needle assembly (40) releasably retains a needle (43) in an extended position in which the sharpened tip of the needle is exposed for use. At the end of an injection stroke, the plunger (30) engages the needle assembly (40), such that the needle (43) is released and retracted into a cavity (38) within the plunger. The device (10) includes structure for reducing the dead-space volume, which represents the amount a fluid remaining in the device at the end of an injection stroke. In addition, preferably the device (10) includes structure for minimizing the volume of potential air bubbles trapped in the medicinal fluid prior to an injection.Type: GrantFiled: March 6, 2001Date of Patent: May 5, 2009Assignee: MDC Investment Holdings, Inc.Inventors: Michael J. Botich, Thor R. Halseth, John Barker

Patent number: 7524306Abstract: A catheter insertion device is provided for inserting an over-the-needle catheter. The device includes an insertion needle that is retractable into the housing of the device after use to prevent exposure to the contaminated needle. A needle retainer releasably retains the needle in an extended position against the rearward bias of the biasing element. The needle retainer engages the hub of the catheter so that when the catheter is removed from the insertion device, the needle retainer automatically releases the needle. The biasing element then propels the needle rearwardly into the housing of the device. The device further allows the operator to intervene to delay retraction if desired.Type: GrantFiled: December 3, 2003Date of Patent: April 28, 2009Assignee: MDC Investment Holdings, Inc.Inventors: Michael J. Botich, Thor R. Halseth, John Barker

Patent number: 7513887Abstract: A medical device is provided for collecting fluid samples from a patient, such as blood samples. The device includes a needle having a forward sharpened tip that is retracted into the housing of the device after use to prevent exposure to the contaminated needle. The rearward end of the housing is open, forming a socket for receiving a fluid container, such as a vacuum tube, that will receive the fluid sample. A needle retainer releasably retains the needle in the extended position against the rearward bias of a biasing element. After use, the medical professional retracts the needle by pressing an actuation button, allowing the biasing element to displace the needle rearwardly. A guide track guides the needle during retraction, tilting the needle off-axis.Type: GrantFiled: January 15, 2003Date of Patent: April 7, 2009Assignee: MDC Investment Holdings, Inc.Inventors: Thor R. Halseth, Michael J. Botich, Robert T. McWethy

Patent number: 7470258Abstract: A method and apparatus for injecting medicine from a pre-filled container into a patient through an injection needle. After use, the needle is automatically shielded to prevent inadvertent contact with the needle. The device operates by pumping medicine out of the vial and into a transfer chamber. The medicine is then expelled from the transfer chamber into a patient during an injection stroke. At the end of the injection stroke, the needle is released for retraction, and the spring retracts the needle for shielding. The device can include an injector assembly and a vial holder assembly. The injector assembly has a needle retainer for releasably retaining the needle in a projecting position against the bias of a spring. The vial holder assembly is attachable with the injector assembly and is operable to transfer fluid from the vial and into the transfer chamber for an injection.Type: GrantFiled: March 13, 2002Date of Patent: December 30, 2008Assignee: MDC Investment Holdings, Inc.Inventors: John M Barker, Thor R. Halseth, Joseph Kovalski, Robert T. McWethy, Bernardo Challiol
