Compressive Element Over Wound Site Patents (Class 602/53)
  • Patent number: 8664464
    Abstract: The invention provides wound dressings comprising an absorbent (porous) hydrogel composition comprising a foam portion which comprises a flexible plasticized hydrophilic polymer matrix having an internal cellular structure, and a continuous portion which comprises a flexible plasticized hydrophilic polymer matrix having relatively continuous internal structure. The continuous portion of the hydrogel composition includes apertures providing fluid flow communication through the continuous portion between an external surface of the continuous portion and the foam portion whereby the foam portion can take up external water or other fluid into the cellular structure through the apertures of the continuous portion. The continuous portion of the hydrogel composition may be tacky to the skin, allowing its use as a bioadhesive.

  • Patent number: 8664465
    Abstract: A pad of elastomeric material having a softness of no more than about durometer 50 Shore 00. The pad may carry adhesive and/or a housing for adhering the pad to a surface, either directly or indirectly through an envelope which surrounds the pad and carries the adhesive. Such a pad exhibits hemostatic and leak prevention properties against needle puncture holes in the skin or the wall of a hollow medical device. Particularly, hemostasis may be prevented with low pressure application of the pad to the skin. The pad may be previously applied to the skin of the patient or a wall of a medical device such as tubing or a solution bag, and the needle may then penetrate both the pad and the skin or medical device wall, to make a resealable puncture with leakage reduction and hemostasis when the needle is withdrawn.

  • Patent number: 8641690
    Abstract: An apparatus for treatment of external hemorrhaging has a panel for applying pressure to an absorbent pad and a wound on a body part. The panel has a central portion located between first and second arms which extend outwardly and in transversely opposed directions from the central portion. The apparatus includes a strap which is attached to the first arm at or near a first strap end, and is releasably attachable to the second arm at an attachment region of the strap spaced apart from the first strap end. When the panel is strapped to the body part, the tension in the strap pulls on and elastically deforms the first and second arms of the panel inwardly toward the body part, and applies localized pressure to the pad and wound.

    Abstract: 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.

    Abstract: A hemostatic device for promoting the dotting of blood includes a gauze substrate, a clay material disposed on the gauze substrate, and also a polyol such as glycerol or the like disposed on the gauze substrate to bind the clay material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood emanating from the wound to cause the clotting. A bandage that can be applied to a bleeding wound to promote the clotting of blood includes a flexible substrate and a gauze substrate mounted thereon. The gauze substrate includes a clay material and a polyol. A hemostatic sponge also includes a gauze substrate and a dispersion of hemostatic material and a polyol on a first surface of the substrate.

  • Patent number: 8313474
    Abstract: An aqueous solution of polyacrylic acid is placed in a mold, frozen, and freeze-dried to form a sponge-like polyacrylic acid structure. The sponge-like polyacrylic acid structure is compressed by the application of heat and pressure to reduce the thickness and increase the density of the sponge-like polyacrylic acid structure to form a densified polyacrylic acid structure. The densified polyacrylic acid structure is preconditioned by heating to form a wound dressing. The wound dressing can be applied to control severe, life-threatening bleeding from a wound at a wound site of a person.

  • Patent number: 8298199
    Abstract: A pressure bandage includes a banding portion having opposite first and second sides. A chamber is formed in the first side of the banding portion. The second side of the banding portion includes a hole in communication with the chamber. A bladder is received in the chamber and receives a fluid. The bladder includes an infiltratable surface permeable to the fluid. The infiltratable surface of the bladder and the first side of the banding portion face the same direction. The fluid received in the bladder is permeable out of the bladder via the infiltratable surface. A control member is engaged with the hole of the banding portion and imparts a pressure to the bladder. The hole can be a screw hole, and the control member includes a knob threadedly engaged with the screw hole such that the knob is rotatable to adjust the pressure imparted to the bladder.

  • Patent number: 8267880
    Abstract: The invention relates to an elastic adhesive unidirectional bandage and to a method for the production and the use thereof. The inventive bandage is embodied in the form of a segment, exhibits elastic and adhesive properties and is designed, in particular for supporting joints and preventing and maximally reducing injuries in certain body regions. The bandage segment is held in position during a long time by means of the adhesive properties thereof and supports natural movements by the elasticity thereof without constrictions and folds. Even, when the bandage is carried for a long time, it does not provoke a foreign body feeling. The bandage segment is easily applicable and optimally anatomically adaptable by the specific design of the elastic areas (for example, only the partial areas of the segment are elastic) and by corresponding shape thereof.
