When treating a bleeding wound, application of the hemostatic sponge causes at least a portion of the hemostatic material to come into contact with blood through the release agent and through the substrate.

  • Patent number: 8777982
    Abstract: A device configured to apply a compressive force to a patient's skin at the site of a wound to assist in hemostasis. The device includes a footplate configured to adhere to the patient's skin, a receiving device positioned on the footplate, a plunger positioned within the receiving device and configured to move through both the receiving device and the footplate such that a downward force applied on the plunger toward the patient's skin results in the plunger moving through the receiving device and the footplate until the plunger contacts the patient's skin, and the plurality of motion restricting components interposed between the receiving device and the plunger, the plurality of motion restricting components configured such that as the plunger moves toward the skin movement of the plunger away from the skin is restricted until the restricting components are released.

  • Patent number: 8759602
    Abstract: Devices and methods are disclosed for achieving hemostasis in traumatized patients. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery or military setting. The patient may have received trauma to abdominal viscera, the thoracic cavity or the periphery. The devices utilize fluid impermeable outer surfaces and distributed pressure to achieve tamponade and hemostasis, primarily by exertion of pressure. The devices come in a variety of configurations including sheet, rolled sheet, folded sheet and polygonal solids including extruded shapes. The devices are capable of serving as carriers for thrombogenic or anti-pathogenic agents. The devices are flexible, bendable, and conformable in their wet or dry state so that they exert distributed pressure on the wound. The hemostatic packing devices may be placed and removed by open surgery or laparoscopic access without generating excessive re-bleeding, and may further comprise antimicrobial or thrombogenic regions.

  • Patent number: 8759603
    Abstract: 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.

  • Patent number: 8674165
    Abstract: A pad of elastomeric material having a softness of no more than about durometer 30 Shore 00. The pad may carry adhesive 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.
