Patent number: 8524973Abstract: The invention provides a wound dressing or therapy compress (100) containing a fill material (108) permanently loaded with an antimicrobial silver. The dressing or compress comprises a flexible upper backing (104) and a lower shell (102) fastened to one another, and each of which comprises a synthetic fabric. The lower shell is fluid-permeable and is adapted to be placed in direct or covered contact with a wound or tissue to be treated. The backing may be either fluid permeable or non-permeable, as desired, to allow for the release or retention of moisture. The shell and backing are joined to one another to form a plurality of fill material enclosures (106) therebetween, each such fill material enclosure containing a zeolite fill material which is permanently loaded with antimicrobial silver. The presence of the silver within the fill material promotes a germ and microbial free environment approximate the shell and within the dressing or compress.Type: GrantFiled: September 17, 2001Date of Patent: September 3, 2013Assignee: Bruder Healthcare CompanyInventors: Mark H.

Patent number: 8512743Abstract: An apparatus for promoting the clotting of blood and controlling bleeding comprises a receptacle for retaining molecular sieve material in particulate form therein. A pad for controlling bleeding comprises a mesh structure and a rigid or semi-rigid support attached to the mesh structure to facilitate the application of pressure to the pad and the wound. A bandage applicable to a bleeding wound comprises a mesh structure and a flexible substrate attached to the mesh structure, the substrate being a cloth or plastic member that may be adhesively attached to cover a wound. In any embodiment, at least a portion of the receptacle or mesh structure is defined by a mesh having openings therein, and at least a portion of the particulate molecular sieve material is in direct contact with blood.Type: GrantFiled: August 29, 2012Date of Patent: August 20, 2013Assignee: Z-Medica, LLCInventors: Jeffrey Horn, Raymond Huey

Patent number: 8500670Abstract: The invention relates to a variable tension chest support for use by patients having undergone thoracic surgery. The chest support may be worn directly on the skin of a patient and comprises a band of stretchable material and one or more grips which are wholly or partially concealed within pockets with which the patient may alter the tension of the chest encircling band. The device allows a patient to modify the level of tension applied to the chest, thus managing the recovery process, while providing a basic level of support at all times the support is in use.Type: GrantFiled: June 20, 2011Date of Patent: August 6, 2013Inventor: Doris Hjorth Hansen

Patent number: 8497408Abstract: High-pressure bleeding wounds (and other bleeding wounds) may be treated by applying direct pressure directly in the bleeding wound, such as by applying a back pressure in a confined space around and in the wound. Certain substances and articles may be inserted into the wound, and the wound may be enclosed with that substance or article (such as a hemostatic substance, which may be polymeric), by swelling on contact with molecules (such as water molecules in the blood) encountered in the wound, generates the desired pressure to stop or at least reduce the bleeding without the detrimental effects of a tourniquet. Clot-inducing substances may be introduced into the wound contemporaneously with direct pressure application directly in the wound. Compressible and non-compressible wounds are treated. Treatment stops bleeding without producing pressure injury or ischemic damage. Medical devices using this technology are provided, including removable, biodegradable, medic-administrable devices.Type: GrantFiled: September 14, 2007Date of Patent: July 30, 2013Assignee: Virginia Commonwealth UniversityInventors: Gary Wnek, Marcus E.

Patent number: 8481803Abstract: A hemostatic device includes a flexible band adapted to be wrapped around a patient's limb at a site on the limb where bleeding is to be stopped, a portion for securing the band in a wrapped state to the limb, a curved plate which is made of a material more rigid than the band and at least a portion of which is curved toward the inner peripheral side thereof, a main balloon which is provided on the inner peripheral side of the curved plate and which inflates when a fluid is introduced therein, and a pressing member which is provided between the curved plate and the main balloon so that at least a portion thereof overlaps with the balloon and which is adapted for pressing against the balloon. The device provides an excellent hemostatic effect and prevents numbness and poor circulation in areas peripheral to the site of attachment.Type: GrantFiled: January 21, 2009Date of Patent: July 9, 2013Assignee: Terumo Kabushiki KaishaInventors: Satoshi Wada, Shigeki Numata, Hiroshi Yagi

Patent number: 8481805Abstract: A method to stop bleeding at a puncture site of an artery on a wrist of a patient comprises wrapping a flexible band of a hemostatic device around the wrist of the patient, wherein the hemostatic device also includes a curved plate, a balloon and a marker used to position the balloon at the puncture site, and wherein the flexible band, the curved plate and the balloon are substantially transparent. The wrapping of the flexible band around the wrist of the patient involves wrapping the flexible band around the wrist of the patient while the balloon is in an uninflated state. The wrapping can also take place while an introducer sheath is in place at the puncture site. The method also involves using the marker to position balloon relative to the puncture site such that the balloon overlies the puncture site, introducing a fluid into the balloon and inflating the balloon, and maintaining inflation of the balloon and compression against the puncture site.Type: GrantFiled: December 21, 2012Date of Patent: July 9, 2013Assignee: Terumo Kabushiki KaishaInventors: Satoshi Wada, Shigeki Numata, Hiroshi Yagi

Patent number: 8469936Abstract: Reduced-pressure medical dressings, systems, and methods involve a dressing with a first barrier layer that desolidifies when exposed to a fluid—typically a liquid—to form a treatment aperture in the first barrier that is used to deliver reduced pressure to a tissue site. The first barrier layer is formed from a desolidifying material. The system includes a drape covering a second surface of a manifold and a portion of the patient's epidermis to provide a substantially sealed space containing a manifold and the first barrier layer. Other systems, dressings, and methods are also disclosed.Type: GrantFiled: June 25, 2010Date of Patent: June 25, 2013Assignee: KCI Licensing, Inc.Inventors: Timothy Mark Robinson, Christopher Brian Locke
