  • Publication number: 20210145451
    Abstract: A hemostatic device is comprised of a covering member that includes a main body to which an inflatable member is connected, a first arm portion extending away from the main body, and a second arm portion extending away from the main body while forming an obtuse angle with a longitudinal direction of the first arm portion. The first arm portion includes an enlarged portion protruding in a width direction of the first arm portion at an end portion of the first arm portion. The second arm portion is longer than the first arm portion and is configured to be secured to the enlarged portion and to be secured to the second arm portion by passing between fingers of the patient in a state in which the second arm portion is wrapped around a limb of a patient.

  • Publication number: 20210145452
    Abstract: A hemostatic device includes a covering member having a main body connected to an inflatable member, a first arm portion extending from the main body, and a second arm portion extending from the main body in a direction different from a longitudinal direction of extent of the first arm portion. The first arm portion is configured to be secured to the second arm portion by virtue of a part of the first arm portion passing between fingers of a patient while the second arm portion is wrapped around a limb of the patient. The second arm portion has a belt portion for wrapping around the patient's limb and a support portion connecting the main body and the belt portion and located on a straight line connecting the first arm portion and the inflatable member. The belt portion is securable to the support portion while wrapped around the patient's limb.

  • Patent number: 10980546
    Abstract: A hemostatic device including a band that is wrapped around a limb of a living body at a site of the living body where bleeding is to be stopped and an inflatable portion which is inflated by injection of gas to cause the inflatable portion to press the site where bleeding is to be stopped. The hemostatic device includes an injection part that injects gas into the interior of the inflatable portion. The injection part includes a hole penetrating the injection part and communicating the housing space with outside environment. The hemostatic device includes a first support plate and a second support plate positioned adjacent one another along the longitudinal direction of the band. The second support plate is movably connected to the first support plate. The inflatable portion is on the first support plate and the injection part is on the second support plate.
